Problems solved by technology

[0002] The grid steel frame for tunnel support uses 8-shaped steel bars as the skeleton steel bars of the steel frame. Generally, the steel bar bending machine is used for manual processing. During the processing, the steel bars need to be bent repeatedly. It is difficult to determine the bending size, and the product qualification rate is low. Low output, large material loss, insufficient safety and reliability

Embodiment Construction

[0035] The following non-limiting examples illustrate the invention.

[0036] Such as Figures 1 to 10 As shown, an 8-shaped steel bar processing equipment is composed of 8-shaped forming equipment and bow-back forming equipment. Formed inner mold 5, limit anti-floating clamps 6, 9, sliding forming outer formwork A7, sliding forming outer formwork B8 and sliding inner mold base plate 10; Figures 1 to 6 As shown, the workbench 1 is located at the bottom as a support, and the limit plate 3 is fixed on it. The sliding inner mold base plate 10 is placed between the workbench 1 and the limit plate 3, and the limit plate 3 limits the sliding inner mold base. The seat plate 10 can only slide on the surface of the workbench 1, and the workbench 1 is also fixed with a sliding forming outer formwork B8, and the sliding inner mold base plate 10 is fixed with a telescopic clamping plate 4 and a sliding 8-shaped inner mold 5. One end of the hydraulic arm 2 is fixed on the worktable 1 an...

Abstract

The invention discloses a device and method for machining a reinforcing steel bar shaped like the Arabic number 8 and belongs to the technical field of tunnels. The device is composed of an 8 shape forming device and an arch back forming device. The 8 shape forming device is composed of a work platen, a hydraulic arm, a limiting board, a telescopic clamping board, an inner sliding 8 shape shaping die, a limiting suspension resistant clamping board, an outer sliding forming template A, an outer sliding forming template B and an 8 shape forming inner sliding die base board. The arch back forming device is mainly composed of a door frame, a hydraulic arm, a movable downward-pressing beam, an ejection head and a stamping table. The method comprises the steps that the inner sliding 8 shape shaping die is sleeved with a machined rectangular reinforcing steel bar and an 8 shape is formed through the outer sliding forming template A and the outer sliding forming template B. The machined reinforcing steel bar shaped like the Arabic number 8 is horizontally placed on the stamping table of the arch back forming device and stamped through the movable downward-pressing beam and the ejection head so that an arch back can be formed. The device for machining the reinforcing steel bar shaped like the Arabic number 8 has the advantages of being high in pass percent, high in production efficiency, good in machining quality and good in safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of tunnels. Background technique [0002] The grid steel frame for tunnel support uses 8-shaped steel bars as the skeleton steel bars of the steel frame. Generally, the steel bar bending machine is used for manual processing. During the processing, the steel bars need to be bent repeatedly. It is difficult to determine the bending size, and the product qualification rate is low. The output is low, the material loss is large, and the safety and reliability are insufficient. Contents of the invention [0003] The object of the present invention is to provide a new type 8-shaped steel bar processing equipment and its processing method, which have the characteristics of high pass rate, high production efficiency, good processing quality, and good safety and reliability. [0004] The object of the invention is achieved through the following technical solutions: [0005] A figure 8 steel bar processing equipme...
