[0002] Stainless steel sheets often need to be bent to form the required shape. In the existing technology, the bending dies do not have positioning devices. The bending position is controlled by bending equipment or manual labor. When the size of the stainless steel workpiece to be bent changes, the control of the stainless steel raw material may be deviated, affecting the accuracy of the bending position and leading to an increase in the defect rate of finished products.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 4 It is known that a stainless steel bending die with positioning includes a concave die 1 and a convex die 2. The concave die 1 has a step 3 on its side, and a first limiting plate 4 is slidably connected on the step 3. A second limiting plate 5 is telescopically arranged on the outside of the first limiting plate 4. The first limiting plate 4 and the second limiting plate 5 position the stainless steel workpiece.

[0018] In practical use, this utility model Adjust the positions of the first limiting plate 4 and the second limiting plate 5 according to the workpiece size and bending position. During processing, place the stainless steel workpiece on the die 1, with the side of the stainless steel workpiece attached to the first limiting plate 4 and the inner end of the stainless steel workpiece attached to the second limiting plate 5. Then, press down the punch 2 to bend the stainless steel workpiece.

[0019] In this mold, a slide groove 6 is provided below the step 3. Two first lead screws 7 are rotatably arranged in the slide groove 6. A connecting plate 8 that moves in the slide groove 6 is provided at the bottom of the first limiting plate 4. The connecting plate 8 is threadedly connected to the first lead screw 7. A worm wheel 9 is fixed at the outer end of the first lead screw 7. A worm 10 that meshes with the worm wheel 9 is rotatably arranged on the outer side of the die 1. A first handwheel 11 is provided at the end of the worm 10.

[0020] Rotating the first handwheel 11 causes the worm gear 10 to drive the two worm wheels 9 to rotate synchronously. The worm wheels 9 are fixedly connected to the first lead screw 7, causing the two first lead screws 7 to rotate synchronously. This causes the connecting plate 8, which is threadedly connected to the first lead screw 7, to drive the first limit plate 4 to move along the direction of the first lead screw 7, thereby adjusting the position of the first limit plate 4.

[0021] Since the second limiting plate 5 is located outside the first limiting plate 4, the movement of the first limiting plate 4 will cause the second limiting plate 5 to move laterally, but will not affect its front and rear positions.

[0022] Multiple first connecting blocks 12 and second connecting blocks 13 extend from the outer side of the first limiting plate 4. The end of the second limiting plate 5 is provided with a guide rod 14 that passes through the first connecting block 12. A second lead screw 15 that is threadedly connected to the guide rod 14 is rotatably provided inside the second connecting block 13. Through holes are opened on the inner sides of the first connecting block 12 and the second connecting block 13. Multiple limiting grooves 16 are evenly distributed on the outer side of the through hole of the first connecting block 12. A limiting strip 17 that cooperates with the limiting groove 16 is provided on the outer side of the guide rod 14, forming a structure in which the guide rod 14 moves within the first connecting block 12 without rotating. A threaded hole is provided inside the guide rod 14. The end of the second lead screw 15 is inserted into the threaded hole. A second handwheel 18 is provided at the end of the second lead screw 15.

[0023] The front and rear position adjustment of the second limiting plate 5 is achieved through the following steps: rotating the second handwheel 18 drives the second lead screw 15 to rotate. The second lead screw 15 is threadedly connected to the guide rod 14, while the guide rod 14 cannot rotate within the first connecting block 12. Therefore, under the action of the rotation of the second lead screw 15, the guide rod 14 will extend and retract within the first connecting block 12, driving the second limiting plate 5 to move back and forth, thereby adjusting its position and completing the positioning of the stainless steel workpiece.

[0024] The limiting strip 17 extending outward from the guide rod 14 cooperates with the limiting groove 16 in the first connecting block 12 to complete the structure that the guide rod 14 can move within the first connecting block 12 but cannot rotate.

[0025] Compared with the prior art, this utility model has the following advantages: by integrating the positioning mechanism into the bending die, the bending position of the stainless steel workpiece can be accurately positioned, reducing operational risks, improving product bending accuracy, and thus ensuring product stability and consistency.
