[0002] Automobile covering parts refer to the spatially shaped surface or internal parts made of metal sheets that cover the engine, chassis, cab and body. Since automobile covering parts are generally formed in one step, stamping is an efficient and fast processing technology that can achieve fast and accurate processing of sheet materials. Secondly, the stamping process is lower in cost than other metal material processing technologies and can also achieve higher efficiency in the production process, so stamping is often used to stamp sheet materials.

[0003] In the prior art, when the stacked sheets are fed into the stamping machine one by one, since automobile covering parts are generally made of metal, when the cutting edges are not straight or there are gaps, small metal debris will appear. The metal debris stays in the mold, which can easily cause crushing during subsequent sheet stamping, reducing the product qualification rate. Therefore, we propose an anti-crushing device for automobile covering parts stamping to solve the above problem. Utility Model Content

Sliding holes are provided on the tops of the two sliding sleeves 7. The inner walls of the two sliding holes are slidingly connected to the outer walls of the two piston rods 8 respectively. The two piston rods 8 compress the air through the up and down movement of the two sliding sleeves 7. A flat-top piston 9 is fixedly connected to the bottom of the piston rod 8. The outer wall of the flat-top piston 9 is slidingly connected to the inner wall of the sliding sleeve 7, and the flat-top piston 9 moves up and down in the sliding sleeve 7.

[0024] An air inlet pipe 10 and an air outlet pipe 11 are fixedly connected to each other on the outer wall of the sliding sleeve 7. A one-way valve 12 is fixedly installed on the outer walls of the air inlet pipe 10 and the air outlet pipe 11. One-way air inlet and outlet are achieved through the one-way valve 12. Two grooves 13 are provided on the inner wall of the machine frame 2. A rectangular plate 18 with a hollow structure is fixedly connected to the inner wall of the groove 13. A plurality of air nozzles 19 are fixedly connected to the outer wall of the rectangular plate 18.

[0025] A winding mechanism is provided inside the groove 13, and the winding mechanism includes two circular sleeves 14. The inner walls of the two grooves 13 are fixedly connected to the outer walls of the two circular sleeves 14 respectively.
