Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a bending and punching mechanism for wrench production. Background Art

[0002] When producing wrenches, the bending and punching processes are usually completed by manually controlled mechanical equipment.

[0003] However, in the prior art, the processing device used for bending the wrench can generally only bend the wrench to a fixed angle. However, for different production requirements, such a processing device has limitations and cannot flexibly adjust the bending angle of the wrench. For this reason, we propose a bending and punching mechanism for wrench production. Utility Model Content

[0004] The utility model provides a bending and punching mechanism for producing a wrench, which solves the above-mentioned technical problems.

[0005] The utility model solves the above-mentioned technical problems with the following solution: a bending and punching mechanism for producing wrenches, comprising a workbench, an inverted L-shaped fixing frame fixedly installed on the edge of the upper end surface of the workbench, a punching device installed on the fixing frame through a lifting control mechanism, a fixing mechanism installed on the upper end surface of the workbench, a first electric push rod fixedly installed laterally on the upper end surface of the workbench, an extrusion block fixedly installed on the free end of the first electric push rod, the extrusion block slidingly cooperates with the upper end surface of the workbench, a baffle plate vertically rotatably installed on the upper end surface of the workbench, a fixing plate fixedly installed on the upper end surface of the workbench on the side of the baffle plate facing away from the extrusion block, a slotted plate fixedly installed laterally on the outer side wall of the baffle plate, and the slotted plate is connected to the fixing plate through an adjusting mechanism.

[0006] Preferably, the lifting control mechanism comprises a second electric push rod vertically fixedly mounted on the upper end surface of the fixing frame, and the free end of the second electric push rod movably penetrates the fixing frame and is fixedly connected to the punching device.

[0007] Preferably, the fixing mechanism includes a through groove transversely opened on the upper end surface of the workbench, and two clamps are symmetrically arranged on the upper end surface of the workbench. The two clamps are respectively slidably connected to the inner side walls of the through groove, and the clamps extend to the bottom of the through groove. A third electric push rod is transversely fixedly installed on the lower end surface of the workbench, and the free end of the third electric push rod is fixedly connected to the corresponding clamp on the same side.

[0008] Preferably, the adjustment mechanism comprises a screw with a transverse thread penetrating the fixed plate, a connecting block is rotatably mounted on the end of the screw, and a connecting shaft rotatably mounted on the connecting block and penetrating the slotted plate.

[0009] Preferably, a support column is fixedly installed at the corner of the lower end surface of the workbench.

[0010] The beneficial effects of the utility model are:

[0011] 1. The baffle is set to limit the support of the wrench, provide a force point for the wrench, and cooperate with the movable extrusion block to realize the bending processing of the wrench. At the same time, the baffle is rotated and installed, and the rotating screw can adjust the inclination angle of the baffle, which can change the bending angle of the wrench to meet different production needs and is more practical;

[0012] 2. The third electric push rod is set to drive the clamping plate to move.
