Description

Technical Field

[0001] This utility model relates to the field of stamping guidance and positioning technology, specifically a guiding and positioning device for stamping dies. Background Technology

[0002] Modern stamping dies all involve the upper die set with the upper die plate closing with the lower die set. The stamping die uses the upper die plate to stamp and form the sheet metal. During the stamping process, the shearing force of the sheet metal reaction will cause the upper or lower die set to be subjected to lateral displacement. For stamping dies with high precision requirements, this lateral displacement must be avoided. Therefore, the guiding and positioning of high-precision stamping dies has become a major issue that needs to be considered.

[0003] According to announcement number CN 214442395 U, a stamping die device relates to the field of dies. It includes a die body and a housing that is slidably connected to the die body. The housing has a placement cavity for placing the die body and an opening for inserting the die body. The opening and the placement cavity are interconnected. The housing is provided with a shielding component for shielding the opening.

[0004] The device is equipped with a baffle to cover the opening. During installation, rotating the baffle opens the opening, allowing the mold body to enter the placement cavity. After the mold body enters the placement cavity, rotating the baffle and connecting it to the cover via an elastic rope ensures the baffle fits snugly against the cover, thus covering the opening and reducing the probability of impurities entering the placement cavity through the opening. However, this device does not provide positioning and guidance for the lower mold base, which can cause instability in the lower mold base during stamping. Utility Model Content

[0005] The purpose of this invention is to provide a guiding and positioning device for stamping dies to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guiding and positioning device for stamping dies, comprising a base, a support rod fixedly connected to the top of the base, a fixed seat fixedly connected to the top of the support rod, a hydraulic cylinder fixedly connected to the top of the fixed seat, an upper die seat fixedly connected to the output end of the hydraulic cylinder, a box fixedly connected to the top of the base, a positioning mechanism provided inside the box, a moving mechanism provided at the top of the inner wall of the box, and a lower die seat provided at the top of the moving mechanism;

[0007] The positioning mechanism includes guide rods, which are fixedly connected to the left and right sides of the inner wall of the box near the bottom. A first hinge frame is symmetrically slidably connected to the surface of the guide rod. A T-shaped plate is fixedly connected to the bottom of the first hinge frame.

[0010] Preferably, the second hinge frame has a threaded hole on its front side that matches the first screw, and the surface of the first screw is threaded into the threaded hole. The left and right sides of the front side of the second hinge frame have holes that match the first limiting rod, and the second hinge frame is slidably connected to the surface of the first limiting rod through the holes. The first limiting rod limits the second hinge frame so that the second hinge frame can only move back and forth as the first screw rotates.

[0011] Preferably, the moving mechanism includes a fixed frame, which is fixedly connected to the top of the inner wall of the box. A second screw is rotatably connected to the back of the fixed frame. A second limiting rod is fixedly connected to the front and rear sides of the fixed frame near the top. A moving block is threadedly connected to the surface of the second screw. A moving plate is fixedly connected to the top of the moving block. A second motor is fixedly connected to the front of the box near the top.

[0012] Preferably, the bottom of the fixing frame is fixedly connected to the top of the fixing plate, and the front of the movable block near the top has a hole that matches the second limiting rod. The movable block is slidably connected to the surface of the second limiting rod through the hole. The second limiting rod limits the movable block so that the movable block can only move back and forth with the rotation of the second screw. The top of the box has a groove that matches the movable block, and the movable block passes through and is slidably connected to the groove.

[0013] Preferably, the top of the movable plate is attached to the bottom of the lower mold base, the front of the fixing frame has a hole that matches the second screw, and the surface of the second screw passes through and is rotatably connected in the hole, and the output end of the second motor is fixedly connected to the front end of the second screw.

[0014] Compared with the prior art, the present invention provides a guiding and positioning device for stamping dies, which has the following advantages:

[0015] The stamping die uses a guide positioning device. Through the positioning mechanism, the lower die base is placed on the moving plate. Then, the first motor is started to rotate the first screw. The rotation of the first screw will drive the second hinge frame to move forward, thereby driving the two hinge rods to move forward. The two first hinge frames move towards each other through the cooperation of the hinge rods, thereby driving the two T-plates to move towards each other, so that the positioning rods are inserted into the holes on the left and right sides of the lower die base. This ensures that the upper die base and the lower die base always maintain an accurate relative position during the die closing and opening process.

[0016] The stamping die uses a guide positioning device. Through a moving mechanism, the lower die base is placed on a moving plate. Then, the second motor is started to rotate the second screw. The rotation of the second screw will drive the moving block to move back and forth, thereby moving the moving plate back and forth to adjust the position of the lower die base, so that the positioning rod can be accurately inserted into the holes on the left and right sides of the lower die base.

[0029] The top left and right sides of the box body 7 have grooves that match the T-shaped plate 83, and the surface of the T-shaped plate 83 is slidably connected to the grooves.

The first limiting rod 89 limits the second hinge frame 86 so that the second hinge frame 86 can only move back and forth as the first screw 88 rotates. Example 2

[0032] Please see Figure 5 Furthermore, based on Embodiment 1, a moving mechanism 9 is obtained.

[0033] The moving mechanism 9 includes a fixed frame 91, which is fixedly connected to the top of the inner wall of the housing 7.
