Description

Technical Field

[0001] The utility model relates to the technical field of tower punching machines, in particular to a tower punching machine with a clamping and conveying function. Background Art

[0002] The turret punching machine, also known as the CNC turret punching machine, integrates mechanical, electrical, hydraulic and pneumatic functions. It is a pressure processing equipment that uses the turret punching machine mold to perform punching and shallow drawing on the plate. The turret CNC punching machine is a precision stamping equipment that uses automated control technology and has the characteristics of high efficiency and high precision. The existing turret punching machine is composed of multiple parts such as the control system, stamping system and clamping system. During the working process, the cylinder drives the clamping piece to clamp the workpiece, and then the processing graphics are input into the CNC system through the input device. After processing and calculation, the stamping system works and the turret tool is turned. The turret is one of the core components of the stamping system. The control system can drive the turret to rotate and replace different tools. The control system controls the stamping system and the clamping system to cooperate with each other to perform stamping work. The positions of the two chucks of the traditional turret punch are fixed, and the distance between the two chucks cannot be changed according to the size of the workpiece. When fixing the workpiece, the workpiece is mostly clamped by the deflection of the clamping piece, and the clamping effect is poor. The clamping piece only fixes one side of the clamped workpiece, and the clamping area is small. The workpiece will tilt downward under the action of gravity, affecting the stamping accuracy. For this reason, we propose a turret punch with clamping and conveying function. Utility Model Content

While clamping the workpiece, it can also form a lifting effect on the workpiece, making the workpiece more stable and improving the stamping accuracy.

[0026] The working principle of a tower punch machine with a clamping and conveying function provided by the present invention is as follows: when using the tower punch machine to punch a workpiece, the processing graphics are input into the CNC system through the input device. After processing and calculation, the workpiece is started to be fixed, and the distance between the two chucks is changed according to the size of the workpiece. The single-chip microcomputer 5 controls the motor 482 to operate, and the output shaft of the motor 482 drives the bidirectional screw rod 481 to rotate. When the bidirectional screw rod 481 rotates forward, the two mounting seats 41 move inward synchronously, and the two chucks also move inward synchronously. When the bidirectional screw rod 481 reverses, the two mounting seats 41 move outward synchronously, and the two chucks also move outward synchronously, and one side of the workpiece is placed on the upper front side of the mounting seat 41.

The clamping method of moving up and down improves the clamping effect of the workpiece. At the same time, as the limit frame 44 moves forward, the rack plate 464 also moves forward synchronously. Because the rack plates 464 are meshed and connected with the longitudinally adjacent gear 2 463, and the gear 1 461 is meshed and connected with the longitudinally adjacent gear 2 463, as the rack plate 464 moves forward, the gear 2 463 rotates synchronously, driving the gear 1 461 to rotate accordingly, and the two lifting plates 462 deflect inward synchronously. When the workpiece is clamped, the lifting plates 462 also deflect into place, forming a lifting effect on the lower end of the workpiece. At this time, the workpiece is fixed, and the single-chip microcomputer 5 controls the operation of the two-axis module 491. The two-axis module 491 moves with the workpiece, and the punch 492 presses down the tool on the turret tool holder 493, cooperating with the movement of the two-axis module 491 to realize the stamping of the workpiece.

[0027] It is worth noting that the single-chip microcomputer 5 disclosed in the above embodiment is an S7-200 single-chip microcomputer, the cylinder 47 is an SC32X100S cylinder, the motor 482 is a 1FT7034-5AK70-1CB1 motor, and the two-axis module 491 is an OMDDHO2 two-axis module.
