Opening and closing angle die

Abstract

The invention discloses an opening and closing angle die which is characterized by comprising an opening and closing angle upper die, an opening and closing angle lower die, pressure blocks and a cushion block, wherein the opening and closing angle upper die comprises an assembling plate and an angle form support plate; four assembling holes are formed in the four corners of the top of the assembling plate; the bottom of the angle form support plate is welded on the bottom surface of the assembling plate; three groups of pressure blocks with different angles are mounted on the front side faceof the angle form support plate; an angle groove is formed in the top of the opening and closing angle lower die; and the cushion block is mounted on the right side face of the top end of the angle groove. The opening and closing angle die is optimized and upgraded to reduce the possibility of halt production due to oil cylinder damage, is small in size, simple in structure, low in production cost, high in processing efficiency and remarkably improved in production efficiency.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to an opening and closing angle mold. Background technique [0002] In the process of making angle steel, it is necessary to use the opening and closing angle mold to process the angle steel. At present, the same kind of mold has the following defects: [0003] 1. When the mold is working, the oil cylinder is used to tighten the workpiece. Since the piston rod bears the force other than the axial direction, the oil cylinder is easily damaged, causing customers to often fail to work normally; [0004] 2. Due to the large size and complex structure, it is difficult to replace the mold and the production cost is high; [0005] 3. Some customers use a few plates of a simple machine as the lower mold, and the upper mold is welded with ordinary sheet metal, resulting in low precision and serious deformation of the processed workpiece, which often fails to meet the technical requir...
