The invention discloses metal part stamping forming equipment, and relates to the technical field of metal part stamping. The punching device comprises a punching assembly, two fixing assemblies distributed up and down are arranged on the punching assembly, four buffering assemblies distributed in a rectangular shape are arranged on the punching assembly, a grinding assembly for grinding a round hole or a round groove in the metal accessory is arranged on the punching assembly, and the grinding assembly comprises a moving column and a rectangular cylinder. A round pipe, a rotary disc and an end disc are arranged below the rectangular barrel, a plurality of second grinding tools and a plurality of third grinding tools which are annularly distributed are arranged on the outer side of the rotary disc and the outer side of the end disc, and a first grinding tool is arranged on the end disc. And the effect of automatically polishing the round hole or the round groove generated by stamping after the stamping of the metal part is finished is achieved, and the production efficiency of the metal part is improved.

The invention discloses a high-pressure-bearing anti-deformation automobile rear longitudinal beam and a machining method thereof, and relates to the technical field of automobiles, the high-pressure-bearing anti-deformation automobile rear longitudinal beam comprises a rear longitudinal beam body, and the two ends of the rear longitudinal beam body are fixedly connected with a third mounting plate and an energy absorption box assembly correspondingly; a first supporting piece, a second supporting piece and a third supporting piece are fixedly installed in the rear longitudinal beam body in sequence, a reinforcing assembly is fixedly installed on the surface of the rear longitudinal beam body and comprises a connecting groove, a connecting steel bar is arranged in the connecting groove, and the connecting steel bar is connected with the reinforcing assembly. A reinforcing block and a reinforcing rib are fixedly installed at the two ends of the connecting steel bar respectively, the reinforcing block is fixedly installed on the inner bent face of the rear longitudinal beam body, and the reinforcing rib is fixedly installed on the outer bent face of the rear longitudinal beam body. According to the high-pressure-bearing anti-deformation automobile rear longitudinal beam, the pressure bearing capacity of the rear longitudinal beam is enhanced through the reinforcing assembly and the supporting piece, and the anti-collision capacity and the anti-deformation capacity of the rear longitudinal beam can be enhanced through the energy absorption box assembly.

The invention relates to the technical field of preparation of wire and cable protection materials, in particular to a preparation method of a wire and cable protection material, which is characterized in that the upper and lower surfaces of a high molecular weight polyethylene material are stab-pressed in a staggered manner through a first stab-pressing assembly and a second stab-pressing assembly, and effective stab-pressing connection of fibers between adjacent layers is realized. According to the innovative process, the stab-resistant and cutting-resistant performance of the material is remarkably improved, so that a final product can bear higher external force impact and cutting, and the performance is excellent in practical application. In the secondary compaction step, the stabbed and pressed material is further compacted through a rear-end compaction assembly, and tight connection and an integrated structure of fibers between adjacent layers are ensured. The overall strength of the material is enhanced, and the durability and stability of the material are improved, so that the product can keep excellent performance in different environments. In the trimming detection step, the trimming detection mechanism precisely trims the edge of the material, and it is ensured that the appearance of the product is neat and the size is accurate.
