Model suitable for triangular profiled bar manufacturing

Abstract

The invention relates to a model suitable for triangular profiled bar manufacturing. The model suitable for triangular profiled bar manufacturing comprises a mounting mold frame, three roller formingstructures and two cover plates, wherein a Y-shaped through hole is formed in the mounting mold frame, the three roller forming structures are correspondingly mounted in channels of the Y-shaped through hole correspondingly, each roller forming structure comprises a U-shaped base, a bearing fixedly installed on the U-shaped base and a roller rotationally arranged on the bearing, screw holes are formed in the positions, corresponding to all the channels of the Y-shaped through hole, of the side wall of the mounting mold frame, screw rods penetrate through the screw holes and abut against the backs of the U-shaped bases, the rollers of the three roller forming structures are in contact with one another and form a triangular gap in the middle, circular through holes are formed in the positions, corresponding to the triangular gap, of the two cover plates, and strip-shaped grooves are formed in the two cover plates corresponding to the rollers. Based on the scheme, by means of the arrangement, metal passing through the model can be machined into a product with the triangular section, meanwhile, the friction between a mold and a machined material can be reduced, the drawing force is small, the machining work efficiency is improved, meanwhile, the overall structure is stabler, and the finished product effect is better.

Description

technical field [0001] The invention belongs to the field of roller mold drawing equipment, in particular to models suitable for making triangular profiled materials. Background technique [0002] Roller die drawing is a drawing process using a drawing die consisting of four driven rollers. Roller die drawing changes the sliding friction between the metal wire and the wall of the fixed die hole into rolling friction. Compared with traditional fixed die drawing, the force of roller die drawing is smaller, which reduces energy consumption and speeds up processing efficiency. The commonly used structure of the existing roll mold is the cross mold shown in the joint production device for rolling and drawing of special-shaped bar products disclosed in the application number CN201820092159.4, which is composed of a pair of vertical rollers and a pair of horizontal rollers. The drawn material passes through The gap between the four driven rollers is processed into the required cro...

Problems solved by technology

However, this kind of roller mold is suitable for processing rectangular materials with different specifications. When it is necessary to process heterogeneous materials such as triangles and other non-vertical planes, this kind of roller mold needs multiple adjustments to process and form the corresponding cross-sectional shape, which greatly affects the processing efficiency. And it will also affect the finish and appearance of the product
