Abstract

The invention relates to the field of machining, in particular to a notching press for a U-shaped workepiece. The notching press is provided with an upper die and a lower die which are arranged longitudinally, wherein the bottom of the upper die is connected with a plurality of positioning rods and provided with a cylindrical punch; the lower die is provided with a plurality of spring sleeves matched with the positioning rods; the middle of the lower die is provided with a U-shaped female die; and two sides of the bottom of the U-shaped female die are provided with annular runners. The notching press for the U-shaped workpiece is reasonable in structural design; the notching machining accuracy is improved by the design of the positioning rods and the spring sleeves; and by the design of the annular runners, echoes generated by stamping can be effectively lowered, and production noises can be obviously lowered.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a U-shaped workpiece notching machine. Background technique [0002] The U-shaped workpiece is mainly punched and formed by a notching machine. The existing notching machine has defects such as low processing precision and high noise. Contents of the invention [0003] Aiming at the technical problems in the prior art, the invention provides a U-shaped workpiece notching machine which can solve the problems of machining accuracy and production noise. [0004] In order to achieve the above purpose, the technical scheme adopted is as follows: [0005] The U-shaped workpiece notching machine is characterized in that it has an upper die and a lower die arranged longitudinally, wherein, [0006] The bottom of the upper die is connected with several positioning rods, and the bottom of the upper die is provided with a cylindrical punch; [0007] The lower mold is provided with...
