Abstract

An adjustment device of a thread rolling machine includes a power source and a push member actuated by the power source. The thread rolling machine has a rolling die set adapted to receive blanks sequentially and a blank pushing plate adapted to forward the blanks to the rolling die set. Thus, the push member can carry out the movement of the blank pushing plate and keep the blank pushing plate distant from the rolling die set to thereby confirm whether each blank forwarded by the blank pushing plate is positioned at the correct place within the rolling die set, to simplify an adjustment operation executed before threading the blanks, and to ensure that the finished products meet the requirements.

Description

Pusher adjustment device for thread rolling machine

The present invention relates to an adjusting device, in particular to a material pushing adjusting device of a thread rolling machine.

As shown in FIG. 1 , the conventional thread rolling machine 1 includes a machine 11, a feeding device 12 disposed on the machine 11 and for placing a plurality of blanks 2, a thread rolling plate assembly 13 disposed on the machine 11 and receiving the blanks 2, and a push plate 14 for pushing the blanks 2 in sequence to the position of the thread rolling plate assembly 13; wherein the thread rolling plate assembly 13 has a fixed thread plate 131, a movable thread plate 132 corresponding to the fixed thread plate 131, and a thread rolling channel 133 formed between the fixed thread plate 131 and the movable thread plate 132.

As mentioned above, when the thread rolling machine 1 is used, the blanks 2 are first output in order through the feeding device 12. When the blanks 2 move to the position corresponding to the push plate 14, the push plate 14 moves back and forth to push the blanks 2 into the thread rolling channel 133 in order. At this time, the movable tooth plate 132 slides along the fixed tooth plate 131 to form the thread of the blanks 2. In this way, the thread rolling operation of the blanks 2 can be completed.

However, after actual use, it is found that before rolling the threads of blanks 2 of different specifications, it is necessary to first adjust whether the position of the blanks 2 pushed by the push plate 14 is correct, and repeatedly perform rolling tests to ensure that the push plate 14 accurately pushes the blanks 2 to the correct position. However, the above adjustment and correction operation is likely to cause waste of the blanks 2. In addition, when the push plate 14 pushes the blanks 2 to the rolling plate assembly 13 in sequence, the movable tooth plate 132 has not yet slid to push the blanks 2 before being taken away, the push plate 14 will not retreat backwards, and the weight and force of the push plate 14 mentioned above also make it impossible for the operator to push it backwards by manpower, resulting in the operator being unable to confirm whether the blanks 2 are pushed into the thread rolling channel 133 due to the obstruction of the push plate 14, resulting in the adjustment and correction operation being time-consuming and labor-intensive, and the work efficiency is poor. Furthermore, if the thread rolling plate assembly 13 fails to take away the blanks 2 smoothly, it is difficult for the operator to take out the blanks 2, resulting in difficulty in subsequent operations, which really needs to be improved.

Therefore, the purpose of the present invention is to provide a pusher adjustment device for a thread rolling machine, which can actively move the pusher plate away from the thread rolling plate assembly to facilitate the operator to quickly adjust and confirm the position of the blank, effectively simplify the pre-adjustment and correction work, and ensure the quality of the finished product.

Therefore, the present invention discloses a material pushing and adjusting device for a thread rolling machine, which comprises a machine platform, a material feeding device disposed on the machine platform and capable of accommodating a plurality of blanks, a thread rolling plate group disposed on the machine platform and receiving the blanks, and a material pushing plate for sequentially pushing the blanks to the positions of the thread rolling plate group, and the material pushing and adjusting device comprises a power source and a push member driven by the power source, so that the push member drives the material pushing plate to be displaced in a direction opposite to the thread rolling plate group, so that the material pushing plate is withdrawn from the original material pushing position, so that the operator can confirm whether the positions of the blanks are accurately pushed into the thread rolling plate group, which not only effectively simplifies the adjustment and correction operation and improves the work efficiency, but also ensures that the finished products formed by subsequent thread rolling meet the requirements.

The above-mentioned other technical contents, features and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiments with reference to the drawings.

Referring to FIG. 2 and FIG. 3, a first preferred embodiment of the pusher adjustment device 3 of the thread rolling machine 4 of the present invention comprises a machine table 41, a feeding device 42 disposed on the machine table 41 and for placing a plurality of blanks 5, a thread rolling plate assembly 43 disposed on the machine table 41 and capable of receiving the blanks 5, and a pusher plate 44 disposed between the feeding device 42 and the thread rolling plate assembly 43, so that the pusher plate 44 can push the blanks 5 arranged in the feed device 42. The output blanks 5 are pushed to the positions corresponding to the rubbing plate set 43 in sequence, wherein the push plate 44 is provided with a top pull portion 45, and the rubbing plate set 43 has a fixed tooth plate 431, a movable tooth plate 432 corresponding to the fixed tooth plate 431, and a rubbing channel 433 formed between the fixed tooth plate 431 and the movable tooth plate 432, and the movable tooth plate 432 can slide along the fixed tooth plate 431.

Continuing with the above, the push adjustment device 3 is arranged on the machine 41 in this embodiment, and the push adjustment device 3 includes a power source 31 arranged on the machine 41, and a push member 32 driven by the power source 31, and the setting position of the push member 32 is relatively set to the setting position of the push latch portion 45, so that the push member 32 pushes the push latch portion 45, thereby linking the push plate 44 to move in the opposite direction of the thread rolling plate assembly 43. In addition, the push latch portion 45 can be arranged on the push plate 44 according to actual conditions, or it can be integrally formed with the push plate 44.

Referring to FIG. 2, FIG. 4-1 and FIG. 4-2, before the rolling operation of the blanks 5 is performed, the rolling plate assembly 43 and the push plate 44 must be adjusted and calibrated to ensure that the distance between the fixed tooth plate 431 and the movable tooth plate 432 in the rolling channel 433 is appropriate, and to ensure that the push plate 44 can push the blanks 5 into the rolling channel 433. Therefore, firstly, a plurality of blanks 5 to be rolled are placed in the feeding device 42, and then the feeding device 42 outputs the blanks 5 in order to the push plate 44, and then the push plate 44 pushes one of the blanks 5 into the rolling channel 433, and the push plate 44 continues to abut against the blank 5, and at the same time, the movable tooth plate 432 is pressed against the blank 5. The force source 31 drives the pushing member 32 to push the pushing portion 45, so that the pushing plate 44 is linked by the pushing portion 45 and displaced in the direction opposite to the thread rolling plate assembly 43, that is, the pushing plate 44 will produce an actuating displacement away from the thread rolling plate assembly 43, so that the pushing plate 44 can be withdrawn, so that the operator can confirm whether the blank 5 is pushed to the correct position, and at the same time confirm whether the distance of the thread rolling channel 433 needs to be adjusted. In this way, the adjustment and correction operation of the thread rolling plate assembly 43 and the pushing plate 44 can be completed quickly, and the thread rolling operation can be performed according to the blanks 5 of different specifications. It not only effectively simplifies the adjustment and correction operation before thread rolling and improves work efficiency, but also ensures that the finished products produced subsequently meet the requirements.

Continuing with the above, after the operator confirms that the blank 5 is at the correct thread rolling position, the power source 31 stops driving the push member 32, so that the push member 32 returns to its original position and no longer pushes the push stopper 45. At the same time, the push plate 44 resumes reciprocating movement to facilitate the continuous pushing of the blanks 5 into the thread rolling channel 433. At the same time, the movable tooth plate 432 slides so that the blanks 5 can be moved between the movable tooth plate 432 and the The fixed tooth plate 431 rolls to form screw threads on the blanks 5, so that the thread rolling operation of the blanks 5 can be completed. Of course, if the blanks 5 are not smoothly taken away by the thread rolling plate assembly 43, the push plate 44 can be pushed outward through the cooperation of the power source 31 and the push member 32, so that the operator can take out the blanks 5 that have not been taken away and perform subsequent inspection and maintenance operations, which greatly improves the convenience of use.

5-1 and 5-2, the second preferred embodiment of the present invention still includes the components described in the first embodiment, and its purpose and function are the same as those of the first embodiment, which will not be described in detail here. The special features of this embodiment are: the push-pull portion 45 is arranged on the machine 41, and the push-pull adjustment device 3 is arranged on the push-pull plate 44, so that the push-pull member 32 is driven by the power source 31 to push the push-pull portion 45 forward, and then the push-pull plate 44 is taken away from the rolling plate assembly 43, which is more conducive to quickly confirming and adjusting the position where the blanks 5 are pushed, effectively simplifying the adjustment and correction work before rolling, and ensuring that the finished products formed by subsequent rolling meet the requirements.

To summarize the above, the pusher adjustment device of the thread rolling machine of the present invention drives the pusher to push the pusher part by the power source, so that the pusher plate produces an actuation displacement away from the thread rolling plate assembly, so that the operator can confirm whether the blank is positioned in the correct position, and at the same time, the blank that is not taken away by the thread rolling plate assembly can be taken out. This not only effectively simplifies the adjustment and correction work before the formal thread rolling, so as to cope with the production of blanks of different specifications, but also improves work efficiency and ensures that the finished products meet the requirements.

However, the above is only to illustrate the preferred embodiment of the present invention, and should not be used to limit the scope of implementation of the present invention. In other words, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention specification should still fall within the scope of the patent of the present invention.
