When spacing pinion rack 43 and spacing tooth's socket 21 meshing cooperation, can fix spacingly to die holder 2 on the horizontal direction, reduced the possibility of rocking.

Referring to fig. 3, a pressing assembly 44 and a positioning assembly 45 are connected to the top limit plate 312, the pressing assembly 44 is used for adjusting the height of the locking mechanism 4, and the positioning assembly 45 is used for locking and positioning the pressing assembly 44 when the pressing assembly 44 reaches a required height. Both hold-down assembly 44 and positioning assembly 45 are located above top stop plate 312.

Referring to fig. 3, the pressing assembly 44 includes a pressing rod 441 and a rebounding pressure spring 442, and the pressing rod 441 sequentially passes through the positioning assembly 45 and the connecting top plate 41 in a sliding manner, and finally passes through the limiting top plate 312 in a sliding manner. The top end of the lower pressing rod 441 is fixedly connected with a lower pressing cap 443 pressed on the limiting top plate 312, and the lower pressing cap 443 is clamped above the positioning assembly 45. The rebound compression spring 442 is sleeved on the lower compression rod 441 at a position between the connecting top plate 41 and the limiting top plate 312.

The sliding fit between the sliding block 51 and the sliding groove 52 horizontally limits the vertical sliding of the connecting side plate 42, and the dovetail-shaped sliding block 51 reduces the possibility that the sliding block 51 falls off from the sliding groove 52.

The implementation principle of the tool clamp for the stamping die in the embodiment of the application is as follows: when the die holder 2 needs to be installed, the die holder 2 is placed in an inner cavity formed by the two limiting assemblies 31. Then, the lower pressing cap 443 is pressed downwards, the lower pressing cap 443 acts on the connecting top plate 41, and the connecting top plate 41 drives the connecting side plate 42 and the limit toothed plate 43 to move downwards, so that the limit toothed plate 43 is engaged with the limit toothed slot 21 on the die holder 2. After the meshing, fix a position the locking by locating component 45 to pushing down subassembly 44, realized the fixed locking of die holder 2 from vertical direction and horizontal direction, reduced the not hard up condition of punching press in-process mould, improved the machining precision.

When the die holder 2 needs to be disassembled, after the limitation of the positioning assembly 45 to the pressing-down assembly 44 is removed, the rebound compression spring 442 generates upward elastic force in the process of recovering deformation, the connecting top plate 41 is pushed to automatically move upwards, and the connecting top plate 41 drives the connecting side plate 42 and the limiting toothed plate 43. The fixed locking of the die holder 2 is released, the worker can directly take off the die holder 2, the complex process of disassembling the bolt in the related technology is avoided, and the convenience of the disassembling or assembling process is improved.
