Abstract

A crimping fixture device for crimping dies includes a crimping seat, a jaw seat, and two clamping modules. The crimping seat has a first part, a second part, and a holding space. The first part forms a receiving accommodation. One side of the jaw seat forms another receiving accommodation. The two clamping modules are received in the two receiving accommodations, respectively. Each clamping module has a clamping plate, a ball, and a screw rod. The clamping plate forms a slotted hole. Each receiving accommodation forms a non-circle stepped hole. Each ball is clamped between the receiving accommodation and the clamping plate by the screw. The ball is protruded in the holding space to abut against a fixing hole of the crimping die. The positions of the ball in the slotted hole and the stepped hole can be adjusted so as to adapt to the crimping dies of different sizes.

Description

Mold clamping and fixing device

The invention relates to a device for clamping and fixing a die, in particular to a clamping and fixing device which can replace dies of different sizes to crimp different terminals.

Generally, the crimping pliers that can replace the die usually use the "die fixing screw" to pass through the screw hole on the head of the crimping pliers and pass through the fixing hole of the die, so that the die is fixed on the crimping pliers. front end.

If you want to crimp different types of terminals, you need to match different dies. When replacing the die in the prior art, it is usually necessary to remove the entire "die fixing screw" to remove the die. However, for different dies, the positions of the fixing holes are not the same. Some fixing holes are in the middle of the side, and some positions deviate from the middle by some distance. For example, the dies of network terminals and the dies of coaxial cable terminals have different models.

The positions of the screw holes in the crimping pliers head of the prior art are fixed, and the types of dies that can be applied are also limited. In addition, when changing the die, it is usually very time-consuming.

Therefore, how to improve the fixing effect and replacement efficiency of the clamping and fixing device of the die through improving the structural design, so as to overcome the above-mentioned defects, has become a subject to be solved in this technical field.

The technical problem to be solved by the present invention is to provide a The clamping and fixing device of the die can be adapted to the dies of different sizes, and the dies can be replaced quickly.

In order to solve the above technical problems, one of the technical solutions adopted by the present invention is to provide a die clamping and fixing device, which includes a crimping seat, a die base and two clamping components. The crimping seat has a first end, a second end and a holding space between the first end and the second end, and the first end forms an accommodating area. The die base is movably arranged on the second end along a clamping direction, and another accommodating area is formed on one side of the die base. Two clamping components are respectively arranged in the two accommodating areas, each of the clamping components has a clamping piece, a spherical member, and a screw, each of the clamping pieces has a screw through hole, and A non-circular slotted hole. Each accommodating area forms a recess, a screw hole, and a non-circular stepped hole. The stepped hole communicates with the holding space from the bottom of the recessed portion, one clamping piece is arranged in each recessed portion, and each screw passes through the screw through hole to lock one clamping piece in the accommodating space. Each of the spherical pieces is clamped between the slotted hole of the clamping piece and the stepped hole of the accommodating area, and protrudes into the holding space to abut against a mouth mold fixing holes. The position of the spherical member can be adjusted in the slot hole and the stepped hole to adapt to different sizes of dies, so that the clamping and fixing device is suitable for clamping and fixing dies of different sizes in the crimping seat.

One of the beneficial effects of the present invention is that the clamping and fixing device of the die provided by the present invention can adopt the same clamping assembly and the structural modeling of the accommodating area, and the spherical part of the clamping assembly is clamped by the clamping piece It is in the accommodation area and protrudes into the holding space to abut against the fixing hole of the die.
