Description

(5) Cut-off Circular Automat

.one

The invention relates to metalworking and can be used in the engineering industry when cutting blanks.

A cutting circular saw is known, containing a circular saw with a drive placed on a frame and a stop interacting with a control switch for controlling the workpiece clamp — designed to set the required length of the workpiece 1.

However, the design of the abutment mechanism in contact with the end surface of the workpiece does not allow marking during and after the cutting process, since handling is required for marking — manual or on a special machine, which reduces productivity and increases labor intensity.

The purpose of the invention is to increase productivity by combining cutting and marking operations.

The goal is achieved by the fact that the emphasis is provided with a percussion actuator and is made in the form of a rod, one end of which is provided with a marker, and the other is installed with the possibility of periodic contact with the moving element of the actuator.

Claims (1)

Cutting circular saw, 5 has a circular saw 1 with a drive 2, a hydraulic clamp and a moving mechanism Sne are shown), as well as an emphasis 3. The stop 3 is made in the form of a marker (.fig.2 in contact with the end face of the workpiece k. at the end of the rod 5 installed in the sleeve 6 with the possibility of axial relocation. The sleeve 6 is attached through the clamping strips 7 and 8 and the shaft 9.9 to the bracket 10. The sleeve 6 has a plate 11 on which the limit switch 12 is mounted with the mechanism 13 on. At the other end of the rod 5 set emphasis H, con clocked with a movable element 1S actuator / for example, of a percussion action, and a strap 16 interacting with a switching device of the circuit breaker 1 The actuator 15 consists of a pneumatic cylinder 17, on the rod 18 of which the slider 19 is fixed, the grippers 20 of the spring 21, the striker 22, and also on the guide tube 23. The guide tube stand 23 has longitudinal grooves 2 for the grippers 20, each carrying 2 rollers 25 each. Along the edges of the grooves 2 and 3C there are plates 2b with a slope interacting with the rollers 25 of the grips 20. the top of rack 23 are placed dinners 27 and pushes 28. At the bottom of the rack 23, a bracket 29 is installed with a rocking 30, having a shock surface 31, “contacting with the stop 1 of the rod 5. The rack 23 is fixed on the U-shaped bracket 32 placed in the plate 3 with movement in the direction of the longitudinal axis of the rod 5. The bracket 32 is provided with a steering wheel 3, which through the shaft 35, the gears Zb interact with the rails 37. The bracket 32 is fixed on the plate 33 by two wedges 38, moved by screws 39. The plate 33 is strengthened by adjustable struts 0. The stop-marker 3 is, Example, head 1 with numbers and letters and can be of any design, including cassette type with a set of brands. Circular saw works as follows. After installation of the workpiece in the machine, the stop of the marking machine with the sleeve and the rod is set to the required size of the segment and fixed by fastening the sleeve with the clamping strips. After that, the bracket moves before contact with the end of the rod and is fixed. The machine enters into operation, the Zag. Feed is fed by an O4 feed mechanism (not shown) to a hydraulic clamp (not shown), clamps the workpiece 1 and after 1-2 seconds the pneumatic cylinder 17 is activated. The grippers 20 are driven by the rod 18 of the pneumatic cylinder 17 and lift striker 22. At the end of the stroke, the end face of the striker 22 presses the pushers 28, cocking the spring 27. When a certain height is reached, the rollers 25 of the grippers 20 roll over the plates 26 with a slant and part the gripper 20, stretch the spring 21 and the ends of the grippers 20 release the hammer 22 . Peak 22, having received a push from pushers 28, falls and through the rocking chair 30, the stop l4, the rod 5, the impact is transmitted to the stop-marking machine 3. The working part of the support-marking machine 3 goes deeper into the end of the workpiece. After that, the pneumatic cylinder 17 returns the grippers 20 down to the initial position, and the saw blade 1 is brought to the workpiece k and cuts it off. After cutting the workpiece k, the cycle is repeated. Thus, the proposed constructive implementation of the stop of the cutting circular saw blade allows to increase productivity. Claims Circular saw machine, containing a circular saw blade placed on the frame and interacting with the workpiece clamp control switch, designed to set the required length of the blank, distinguished by the fact that, in order to increase productivity by combining cutting and marking operations, the emphasis is provided with a drive percussion action and is made in the form of a rod, one end of which is provided with a marker, and the other is installed with the possibility of periodic contact with the movable one. drive element.
