High-frequency preheating angle steel angle opening and closing machine

Abstract

The invention discloses a high-frequency preheating angle steel angle opening and closing machine. The high-frequency preheating angle steel angle opening and closing machine is characterized in that one side of the upper plane of a rack is provided with an angle steel supporting block; a pressing oil cylinder is longitudinally arranged above the angle steel supporting block in a supporting way through a support; an auxiliary hydraulic pressure station is arranged at the outer side of the support; a punching oil cylinder is horizontally arranged at the other side of the upper plane of the rack; a main hydraulic pressure station is arranged at one side of the rack, and the main hydraulic pressure station is connected with the punching oil cylinder through a high-pressure oil pipe. Through the arrangement, when the high-frequency preheating angle steel angle opening and closing machine disclosed by the invention is used for opening and closing an angle, a piece of angle steel is firstly heated by utilizing a heating block, then angle opening and closing punching can be carried out on the angle steel, the angle steel is enabled not easy to crack, the machining is once completed, and the machining production quality is ensured.

Description

technical field [0001] The invention relates to a processing equipment for electric poles and towers, in particular to a high-frequency preheating angle steel opening and closing angle machine for angle steel opening and closing angles. Background technique [0002] The poles and towers used on the transmission line are produced and processed with angle steel. In the prior art, when the angle steel is opened and closed, the direct cold stamping process is easy to cause the angle steel to crack or the processing is not in place, the quality effect is poor, and the use requirements cannot be met. Contents of the invention [0003] The object of the present invention is to provide a high-frequency preheating angle opening and closing angle machine for angle iron processing. [0004] In order to achieve the above object, the present invention is provided with an angle steel support block on one side of the upper plane of the frame, and a compression oil cylinder is longitudina...
