In the existing technology, the reinforcing ribs of automobile inner side panels are mostly formed in one piece using a stamping process. The existing stamping forming equipment for reinforcing ribs all require manual removal of the stamped workpiece. However, manual material removal increases the risk factor for operators, increases their workload, and reduces their work efficiency. Based on this, this utility model designs a high-strength stamping die for reinforcing ribs of automobile inner side panels to solve the above problems. Utility Model Content

[0023] A lower mold 5 is fixedly installed between the inner surfaces of the base 1. A forming cavity 6 with openings at both ends and the top surface is fixedly opened inside the lower mold 5. Two symmetrically arranged material placement grooves 7 are opened on the top of the lower mold 5. Two symmetrically arranged sliding holes 8 are opened inside the lower mold 5 and communicate with the forming cavity 6. A discharge push plate 9 is slidably connected inside the lower mold 5 through the two sliding holes 8. The shape of the discharge push plate 9 is adapted to the shape of the forming cavity 6.

[0024] The material placement groove 7 is located above the molding cavity 6. The top surface of the unloading push plate 9 is lower than the material placement groove 7. The back of the lower mold 5 and the positions corresponding to the two material placement grooves 7 are fixedly installed with baffle plates 17.

[0025] Guide rods 10 are fixedly installed on both sides of the lower mold 5. The inner wall of the unloading push plate 9 is slidably connected to the two guide rods 10. The two guide rods 10 are fitted with anti-compression springs 11 on their circumferential sides. Two symmetrically arranged traction components are installed on the surface of the unloading push plate 9. One end of each traction component is fixedly connected to the driven table 4. The back of the base 1 is fixedly installed with a discharge nozzle 12.

[0026] The traction assembly includes a traction rope 13, a connecting seat a14, and a connecting seat b15. The back of the connecting seat a14 is fixedly connected to the lower mold 5, and the bottom surface of the connecting seat b15 is fixedly connected to the top seat 2. Guide wheels 16 are rotatably connected to the inner walls of both the connecting seat a14 and the connecting seat b15. One end of the traction rope 13 is fixedly connected to the unloading push plate 9, and the other end of the traction rope 13 is fixedly connected to the driven table 4. The circumferential side of the traction rope 13 is in contact with the two guide wheels 16. A wire-hauling groove that mates with the traction rope 13 is fixedly opened on the surface of the guide wheel 16. A wire-passing hole that mates with the traction rope 13 is opened on the top surface of the top seat 2 at the positions corresponding to the two traction ropes 13. The diameter of the wire-passing hole is 1.2 times the diameter of the traction rope 13.

[0027] It also includes a support plate 18, the surface of which is fixedly connected to the corresponding upright, and a control panel 19 is fixedly installed on the end face of the support plate 18.

[0028] Working Principle: This device is mainly suitable for the stamping and forming of reinforcing ribs on the inner side panels of automobiles. The shape of the forming cavity 6 is the same as the shape of the inner side panel reinforcing rib. In the initial state, the stamping push rod 3 is fully retracted, and the distance between the unloading push plate 9 and the discharge nozzle 12 is at its minimum. Before stamping, the blank to be stamped is placed into the feeding groove 7. When the blank is placed, the baffle plate 17 effectively limits the position of the blank. During stamping, the stamping push rod 3 drives the driven table 4 to move downward. When the driven table 4 moves downward, the distance between the unloading push plate 9 and the discharge nozzle 12 gradually increases. When the bottom surface of the lower die 5 is in contact with the top surface of the blank, the distance between the unloading push plate 9 and the discharge nozzle 12 is at its minimum. In the large state, the end face of the unloading push plate 9 and the sliding hole 8 remain in contact. After contact, it does not affect the forming operation of the blank in the forming cavity 6. When the driven table 4 continues to move downward, the blank is formed in the forming cavity 6 under the action of the upper mold 20. After the forming is completed, the driven table 4 gradually resets upward. During the reset process of the driven table 4, the unloading push plate 9 gradually approaches the discharge nozzle 12 under the action of the anti-compression spring 11. During the movement of the unloading push plate 9 towards the discharge nozzle 12, the unloading push plate 9 then pushes the formed workpiece out of the forming cavity 6. The pushed workpiece flows out through the discharge nozzle 12 to the workpiece collection device.
