Clamping device for clamping machine

The present invention relates to a clamping device design, and more particularly to a clamping device for a mold clamping machine.

Referring to FIG. 1 , the conventional mold clamping machine 1 includes a machine table 11 , a feeding device 12 for outputting a whole row of blanks 2 , and a clamping device disposed on the machine table 11 for clamping the blank 2 . And a first mold 14 and a second mold 15 which are respectively disposed on the machine 11 and corresponding to each other; wherein the clamping device 13 has a seat 131 disposed on the mold forming machine 1 A connecting seat 132 that slides on the base 131, and a clamp 133 disposed on the connecting base 132 and moving in synchronization with the connecting base 132.

Continuing the foregoing, at the time of manufacture, the blank 2 is first transported to a position by the feeding device 12, and the clamp 133 is disposed at a position corresponding to the position between the first mold 14 and the second mold 15 so that the The jig 133 can sandwich the blank 2 to the position of the preliminary press working, that is, between the first and second molds 14, 15 to increase the smoothness of the forging press processing.

However, the conventional clamp 133 is fixed to the connecting seat 132, and the feeding operation of the blank 2 is performed by sliding on the connecting seat 132; however, since the closing process of the first and second molds 14, 15 is easy to cause When the jig 133 is pressed and deflected, and the jig 133 shown in FIG. 2 is displaced toward the first mold 14, since the jig 133 is rigidly disposed, the jig 133 is easily deformed. Even if a fracture occurs, the service life of the jig 133 is greatly reduced, and improvement is needed.

Therefore, the object of the present invention is to provide a clamping device for a mold clamping machine which has a skewable margin characteristic, thereby preventing the deformation or breakage of the clamp during the feeding process, thereby effectively Extend its service life.

Therefore, the clamping device of the novel molding machine includes a seat body disposed on the mold forming machine, a connecting seat that can slide on the seat body, and a set on the connecting seat and The connecting seat synchronously generates a moving clamp; wherein the connecting seat protrudes from a positioning rod, and the positioning rod is provided with one end of the clamping rod, such that a distance is generated between the clamping piece and the connecting seat, and a spacing is provided in the spacing Retrieving the member, and the two ends of the returning member are respectively mounted on the wall surface of the clamp and the connecting seat; so that the recovery member has elastic recovery characteristics, if the clamp is in the process of feeding the blank material, the mold is The closing process causes the clamp to be deflected and deflected, and the returning member can provide a deformation margin for the deflection of the clamp, which not only can effectively prevent the clamp from being broken by being squeezed, but also can greatly extend the service life of the clamp.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention.

Referring to FIG. 3 and FIG. 4, the new mold clamping machine 3 includes a machine table 31, a feeding device 32 for outputting the blanks 4 in a row, and a set on the machine table 31 for sandwiching the blanks 4 The clamping device 33 and the first mold 34 and the second mold 35 respectively disposed on the machine table 31 and corresponding to each other.

Continuing the foregoing, the clamping device 33 has a seat body 331 disposed on the mold clamping machine 3, a connecting seat 332 slidable on the base body 331, and a base 332 disposed on the connecting base 332. A movable clamp 333 is synchronously generated with the connecting base 332, and the connecting rod 332 protrudes from a positioning rod 334, and the positioning rod 334 can be pivoted at one end of the clamp 333, so that the clamp 333 and the connecting base 332 are disposed. A spacing member is formed, and a returning member 335 is disposed in the spacing. The two ends of the restoring member 335 are respectively connected to the wall surface of the clamp 333 and the connecting base 332. In this embodiment, the clamp 333 and the connecting base 332 are disposed. A sliding rod 336 can also be disposed in the distance between the two, and the sliding rod 336 can be disposed through the returning member 335, and the sliding rod 336 can be displaced by the clamp 333, and the sliding rod is provided below. 336 is illustrated as an example.

The connector 332 can be further divided into a base 3321 that can slide on the base 331 , a movable seat 3322 disposed on the base 3321 , and a movable seat 3322 . a locking member 3323 on the base 3321, and a plurality of fixing holes A are formed in the base 3321. The clamp 333 is fixed on the movable seat 3322, so that the movable seat 3322 is received by the locking member. 3323 is fixed to the fixing hole A, and the following is taken as an example in which the connecting seat 332 has the base 3321, the movable seat 3322, and the locking member 3323.

Referring to FIG. 3 to FIG. 6, when the feeding device 32 conveys the blank 4 to a position, the clamp 333 is disposed on the clamp 333 corresponding to the clamping device 33 between the first die 34 and the second die 35. After the blank 4, the second mold 35 is moved and closed in the direction of the first mold 34 to clamp and position the blank 4, so that the clamp 333 holding the other end of the blank 4 is indirectly received by the second mold. 35 is interlocked to cause deflection in the direction of the first mold 34. At this time, the return member 335 has the characteristic of elastic recovery and the sliding rod 336 can be displaced by the clamp 333 thereon, so the return member 335 And the sliding rod 336 is contracted toward the clamp 333, and is returned to the original shape after the clamp 333 releases the blank 4, thereby absorbing and buffering the force of the clamp 333 to provide deflection of the clamp 333. The deformation margin can not only effectively prevent the clamp 333 from being broken by being squeezed, but also greatly prolong the service life of the clamp 333.

As shown in FIG. 7 , the clamp 333 is fixed on the movable seat 3322 , and the movable seat 3322 is fixed on the fixing hole A of the base 3321 by using the locking member 3323 , so that the movable seat 3322 can be The positions of the first and second molds 34, 35 are adjusted to the position, and the characteristics of the base 3321 can be slid on the seat 331 to increase the fluency of gripping and transporting the blank 4.

In summary, the clamping device of the novel molding machine utilizes the elastic recovery characteristic of the recovery member, so that when the second mold is closed toward the first mold, the positioning is clamped and conveyed by the clamp. In the case of the billet, the recovery member can provide a deformation margin for the deflection of the jig, which not only can effectively prevent the jig from being broken by being squeezed, but also can greatly prolong the service life of the jig.

However, the above description is only for the purpose of illustrating the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the new specification. All should remain within the scope of this new patent.
