The present utility model is a limiting mechanism for a bending die, which is characterized in that a guide piece and a limit piece are provided, the guide piece is There is a guide block and a mounting plate vertically arranged with the guide block, and the mounting plate is provided with a pin for fixing with the mold; the limit piece is provided with a limit block, and the limit block is provided with a U-shaped through-hole along the direction of its central axis. The U-shaped through slot is clamped in the guide block and the limit block moves back and forth along the guide block. There are fastening screws that make the limit block tightly fit with the mold.

The technical problem to be solved by the present invention can be further realized by the following technical solutions, the length of the guide block is much smaller than the length of the U-shaped through groove.

The technical problem to be solved by the present invention can be further realized by the following technical solutions, wherein the length of the guide block is a quarter of the length of the U-shaped through groove.

The technical problem to be solved by the present invention can be further realized by the following technical solutions, the thickness of the guide block is greater than that of the limit block.

The technical problem to be solved by the present utility model can be further achieved by the following technical solutions. The pins are provided with two pins, both of which are internally threaded pins, and the two internally threaded pins are arranged vertically and are on the same vertical plane as the guide block. superior.

The technical problem to be solved by the present utility model can be further realized by the following technical solutions, the mounting plate is evenly provided with four inner hexagonal cylinder head screws for fixing, and the two inner threaded pins are located in the four inner hexagonal cylinder head screws. between the head screws.

The technical problem to be solved by the present invention can be further achieved by the following technical solutions, wherein the fastening screw is a hexagon socket head screw.

Compared with the prior art, the utility model is provided with a guide piece and a limit piece, the limit block of the limit piece is clamped on the guide block of the guide piece, and the limit block can only move forward and backward under the guidance of the guide block, not There will be rotation, the movement range of the limit block determines the width of the bending sheet, and the guide block is fixed through the mounting plate, which is precisely connected to the mold part through a pin with an internal thread and four socket head cap screws. Assembled together, its structure is convenient and fast to use, and it is suitable for various punching and blanking parts to be bent and used, and at the same time, it is convenient for replacement and maintenance.

Detailed ways

The specific technical solutions of the present utility model are further described below with reference to the accompanying drawings, so as to facilitate those skilled in the art to further understand the present utility model, but not to limit the rights thereof.

Referring to Figures 1-4, a limit mechanism for a bending die is provided with a guide and a limit, the guide is provided with a guide block 2 and a mounting plate 1 arranged perpendicular to the guide block 2, the mounting plate 1 is provided with pins 7 for fixing with the mold. The pins 7 are provided with two pins, both of which are internally threaded pins, and the two internally threaded pins are arranged vertically and are on the same vertical plane as the guide block 2 .

The mounting plate 1 is evenly provided with four socket head cap screws 6 for fixing the mounting plate 1 and the mold together, and two internally threaded pins 2 are located between the four socket head cap screws 6 .

The limiter is provided with a limit block 5, and the limit block 5 is provided with a U-shaped through groove 4 along the direction of its central axis. In the block 2, the limit block 5 is moved back and forth along the guide block 2. The other end face of the limit block 5 opposite to the open end of the through slot 4 is set as the reference surface, and the U-shaped through slot 4 is also provided with a limiter. The block 5 is a fastening screw 3 that is tightly fitted with the mold. The tightening screw 3 is a hexagonal socket head screw, and a washer can be added during use, so that the limit block 5 is pressed against the working surface of the mold. The length of the guide block 2 is a quarter of the length of the U-shaped through groove 4 . The thickness of the guide block 2 is greater than that of the limit block 5, which facilitates the limit block 5 to move back and forth along the guide block 2 without falling off and easy to locate.

When in use, according to the width of the bending plate, loosen the fastening screw 3 and adjust the position of the limit block 5. The limit block 5 can only move forward and backward under the guidance of the guide block 2 . The range of movement determines the width of the bent sheet. The position of the guide block 2 is ensured by the pins on the mounting plate 1. The mounting plate 1 is precisely assembled with the mold parts by means of pins 7 and four socket head cap screws 6, so that the sheet material will not rotate during use.
