Long rectangular table hydraulic punching machine

Abstract

The invention discloses a long rectangular table hydraulic punching machine. The long rectangular table hydraulic punching machine comprises a stander, oil cylinders, slide plates, slide plate supporting plates, a row of upper mold carriers, a lower mold, a lower mold carrier and a worktable, wherein a punching needle is respectively, correspondently and detachably installed below each upper mold carrier, a pressure plate is arranged below the row of punching needles, the lower die is arranged below the pressure plate, the row of punching needles is divided into a plurality of groups, each group is provided with 4 to 6 punching needles, each group of punching needles is respectively and sequentially arranged in a staircase shape from high to low, and the height difference between every two adjacent punching needles is 6cm to 10cm. The long rectangular table hydraulic punching machine is provided with a row of punching needles, the punching needles are divided into a plurality of groups, each group of punching needles is sequentially arranged from high to low in a staircase shape, thus a row of holes can be sequentially punched in several times in one-step pressing process of the oil cylinders, the pressure of each oil cylinder can be reduced, the bending deformation of materials and parts can be avoided, all holes can be punched in one step, the repetition in fixation and punching is not needed, and the precision and efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a hydraulic punching machine with a long rectangular platform. Background technique [0002] Existing punching equipment can punch single or multiple holes. When there are many holes in a row, stamping at the same time will cause a large deformation of the material, and the distance between the holes cannot meet the size requirements, and the punched holes after deformation are not smooth enough, which will lead to more burrs. Use also is to produce very big wear and tear to punching machine at the same time, has shortened service life. If only a single or a small number of holes are punched together, it will lead to low efficiency, and every time the position is fixed, an accuracy error will occur, which will affect the accuracy of the entire workpiece. Contents of the invention [0003] The object of the present invention is to provide a hydraulic punchin...

Problems solved by technology

When there are many holes in a row, stamping at the same time will cause a large deformation of the material, and at the same time, the distance between the holes cannot meet the size requirements, and the punched holes after deformation are not smooth enough, which will lead to more burrs. At the same time, it also causes a lot of wear and tear on the punching machine, shortening the service life

If only a single or a small number of holes are punched together, it will lead to low efficiency, and every time the position is fixed, there will be an accuracy error, which will affect the accuracy of the entire workpiece
