Continuous bending machining machine for steel structure sectional materials

Abstract

The invention relates to the technical field of steel machining, and specifically relates to a continuous bending machining machine for steel structure sectional materials. The continuous bending machining machine comprises a base, two pressing rollers used for pressing T-shaped steel are arranged on the upper side of the base, and a V-shaped plate used for removing sundries on the surface of the T-shaped steel is arranged on the feeding sides of the pressing rollers. Two horizontally-arranged inserting rods are symmetrically installed on the inner surface of the V-shaped plate, the end, away from the V-shaped plate, of each inserting rod is sleeved with a sleeve, the end, away from the corresponding inserting rod, of each sleeve is fixedly connected with a protruding block, and the position, provided with an internal threads, of each sleeve is in threaded connection with an external thread disc. A pin hole communicating with an inner hexagonal hole is formed in the face, away from the corresponding inserting rod, of each outer threaded disc, a pressing rod is inserted in each pin hole, and each pressing rod is sleeved with a reset spring. Compared with the prior art, the continuous bending machining machine has the following beneficial effects that dirt left on the upper surface of the horizontal section of the T-shaped steel is conveniently and rapidly removed, and the situation that due to the fact that the dirt is accumulated at the positions of the pressing rollers, the service life of the pressing rollers is influenced is prevented.

Description

technical field [0001] The invention relates to a continuous bending machine for steel structure profiles, which belongs to the technical field of steel processing. Background technique [0002] Steel structures are generally made of profiles, among which T-shaped steel is a type of profile. T-shaped steel is named because its cross-section is the same as the English letter "T". There are two types of T-shaped steel: one is directly cut with H-shaped steel. Divided into T-shaped steel, it is an ideal material to replace double-angle steel welding. It has the advantages of strong bending resistance, simple construction, cost saving and light structure weight. The other is hot-rolled one-time forming T-shaped steel, which is mainly used in machinery and small hardware filling steel, etc. When the T-shaped steel is used for special parts, it needs to be bent to make the T-shaped steel form a certain arc. [0003] During the bending process of T-shaped steel, the position of T...

Problems solved by technology

[0003] During the bending process of T-shaped steel, the position of T-shaped steel is often guided and restricted by the joint action of pressure roller and supporting roller, but the residual dirt on the horizontal section of T-shaped steel is easy to accumulate on the pressure roller, causing the pressure roller to Unbalanced and damaged, affecting the service life of the pressure roller
