Description

Technical Field

[0001] The invention relates to the technical field of automobile welding, in particular to a punching die with a flipping function for an automobile gearbox. Background Art

[0002] Punching dies are equipment used to process materials into parts during processing. They are called cold stamping dies. At room temperature, a die head installed on a press machine is used to apply pressure to the material in the die to produce a hole-like structure, thereby obtaining the desired parts. The surface of the automobile gearbox case at different positions has multiple hole-like structures for installing shafts, which are formed by punching.

[0003] Since the gearbox case structure is relatively complex, there are multiple surfaces at different positions that need to be punched. The punching die of the prior art needs to manually adjust the position of the workpiece in the die for multiple times during the punching process to perform punching processing at various positions of the automobile gearbox. The workpiece is clamped and fixed on the workbench by the die chuck. Since the chuck for clamping the workpiece is a fixed structure and cannot be moved, when adjusting the punching position of the workpiece, it is necessary to manually use external tools to loosen the clamping chucks on both sides of the bottom of the workpiece, take out the workpiece and adjust it to a suitable position, and then tighten the clamping chucks with external tools. As a result, every time the processing position needs to be changed, the operator needs to perform the above operation once, which is too complicated to operate, reduces the processing efficiency, and is time-consuming and labor-intensive. Summary of the invention

[0007] The locking mechanism consists of a locking knob, a T-shaped slider, a locking gear, a matching rack, a limiting rod, and a limiting rack. A T-shaped slot is provided at the bottom of the inner expansion box, a T-shaped slider is provided in the T-shaped slot, a matching rack is welded on the top of the T-shaped slider, a locking gear is provided on the upper side of the T-shaped slot, a mounting hole is provided at the front end of the inner expansion box, the front end of the locking gear extends through the mounting hole to the outside of the inner expansion box and is welded with a locking knob, a matching hole is provided at the front end of the chassis, the locking knob extends through the matching hole to the outside of the chassis, the locking gear is meshed with the T-shaped slider through the matching rack, a limiting rod is welded at the bottom of the T-shaped slider, a limiting rack is welded on the left side wall of the limiting rod, and the limiting rack is used in conjunction with the protruding part of the adjusting gear.

[0008] The beneficial effects of the present invention are as follows: the present invention adds a lifting mechanism, a locking mechanism, and an angle adjustment mechanism. Through the cooperation between the locking mechanism, the lifting mechanism, and the angle adjustment mechanism, before work, the adjusting dial is manually rotated, and the adjusting dial drives the adjusting gear to rotate through the connecting shaft. At this time, the adjusting gear drives the telescopic rod to slide up and down through the adjusting rack matched with it, thereby driving the bottom template at the upper end of the telescopic rod to move up and down. When a certain height is reached, the locking knob is manually rotated, and the locking knob rotates to drive the locking gear on the rear side to rotate. The locking gear drives the T-shaped slider to slide left and right in the T-shaped slide groove provided at the bottom of the inner expansion box through the matching rack meshed with it, thereby making the limit rod at the bottom of the T-shaped slider slide.

At this time, the adjusting gear is locked by the cooperation of the adjusting rack and the limit rack, thereby forming a fixed height of the bottom template. At the same time, the power supply of the small oil cylinder is turned on, and two small The oil cylinder forms a clamping effect on the workpiece on the upper side of the bottom template, and then the punching process can be started. When the punching position needs to be adjusted, the locking knob is turned to make the limit rod move away from the adjusting gear. At this time, the adjusting gear loses its limiting effect, and the adjusting dial can be rotated. The adjusting dial is manually turned to make the bottom template drop. At this time, the workpiece loses the support and fixation of the bottom template, and the small motor switch is turned on. The small motor drives the rotating shaft to rotate, so that the small oil cylinder rotates, thereby causing the workpiece clamped by the small oil cylinder to flip over. When it flips to a suitable angle, the small motor switch is turned off, and the bottom template is raised again to support and fix the workpiece so that processing can continue. Through this design, when punching a workpiece that requires multi-sided processing, there is no need to manually loosen and clamp the chuck repeatedly through external tools to adjust the angle of the workpiece in the punching die, thereby effectively saving the output of manpower and material resources, and when clamping molds of different heights, the height can be adjusted by adjusting the lifting of the bottom template, thereby effectively improving the practicality of the present invention.
