Description

Technical Field

[0001] The utility model belongs to the technical field of die positioning devices, and particularly relates to a stamping die positioning device. Background Technique

[0002] A stamping die is an indispensable tool in the cold stamping process of metal or non-metal sheets. By applying pressure on a stamping machine, the material is separated or plastically deformed to obtain the required parts or semi-finished products. Most stamping dies are composed of an upper die base and a lower die base. The upper die base is connected to the stamping equipment, and the lower die base is fixed below. Therefore, it is necessary to position and fix the lower die base. However, in actual production, the stamping dies used are diverse, and their external dimensions are also different. Common devices can only clamp and position specific stamping dies, restricting their usage scenarios.

[0003] Secondly, most common stamping die positioning devices perform clamping and positioning through a fully manual method, resulting in high labor consumption. Moreover, to achieve firm fixation, it is rather laborious to release the positioning of the stamping die by the positioning device, causing certain inconvenience in its use.

[0004] In summary, there are some problems with the common stamping die positioning devices that use manual methods for fixation and are only suitable for specific specifications of stamping dies. Therefore, it is desired to propose a new structure to solve the above technical problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a stamping die positioning device to solve the problems mentioned in the above background technique.

The screw holes at the front and rear ends have opposite helix directions and are screwed with the external threads at both ends. The external threads on the outer side surface of the screw rod are screwed with the screw holes, so that the rotation of the screw rod can drive the movable clamping mechanism to move back and forth.

[0009] As a preferred embodiment, a cylinder seat is provided on one side of the movable slider close to the center of the device body. A clamping cylinder is provided on one side of the cylinder seat close to the center of the device body. A connecting stud is provided at one end of the clamping cylinder close to the center of the device body. Starting the clamping cylinder can push the clamping seat to move, so that the clamping angle block is engaged with the corner of the lower die seat to clamp and position it.

[0010] As a preferred embodiment, a connecting column is provided on one side of the clamping seat away from the center of the device body. A connecting threaded hole is opened on the side surface of one end of the connecting column away from the center of the device body;

[0011] The connecting threaded hole is in threaded fit connection with the connecting stud. A clamping angle block is provided on one side of the connecting column close to the center of the device body. A mold table is provided below the sliding seat. Screwing the connecting stud into the connecting threaded hole can fix the connection between the movable clamping mechanism and the clamping seat.

[0012] As a preferred embodiment, an upper clamping threaded hole is opened on the upper surface of the clamping angle block, and an upper clamping stud is provided inside the upper clamping threaded hole.

[0013] As a preferred embodiment, the upper clamping stud is in threaded fit connection with the upper clamping threaded hole. An upper clamping plate is provided below the upper clamping stud. Rotating the upper clamping stud can make it rotate inside the upper clamping threaded hole, so that the upper clamping plate performs secondary positioning on the upper surface of the lower die seat, and the positioning effect can be improved.

[0014] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By adding the device body, the movable clamping mechanism, the clamping seat, the belt pulley and the belt, starting the rotating motor to drive the screw rod to rotate, the right end belt pulley transmits the rotation to the left end screw rod through the connection of the belt, so that the left and right screw rods drive the two movable clamping mechanisms to move back and forth respectively, and adjust to the corner of the lower die seat. Starting the clamping cylinder drives the clamping seat to move, so that the clamping angle block is engaged with the corner of the lower die seat, thereby facilitating the clamping and positioning of the die seat. By adding the clamping seat, rotating the upper clamping stud can make it rotate inside the upper clamping threaded hole, so that the upper clamping plate performs secondary positioning on the upper surface of the lower die seat, and the positioning effect can be improved.
