Example Embodiment

[0013] Example

[0014] In this embodiment, a press for bending a zigzag rebar is as follows figure 1 As shown, the polygonal rebar is used for concrete embedded parts, and includes a first processing mold and a second processing mold. The first processing mold includes a first upper mold and a first lower mold, and the first The upper mold is arranged opposite to the first lower mold; the first upper mold includes a first upper mold body, and the first upper mold body is provided with a first U-shaped punch with an inner card shape and a straight rounded belt. The upper end of the first punch is parallel to the lower end, and the outer side of the first punch is provided with a first upper die arc groove with the same diameter as the round steel to be bent; the first lower die includes a first lower die The body, the first lower die body is provided with a first U-shaped support frame that matches the first punch, and both open ends of the first U-shaped support frame are provid...

Abstract

The invention relates to a press machine device for bending a deformed steel bar in a shape of a Chinese character 'ji'. The device comprises a first machining die and a second machining die, the first machining die comprises a first upper die and a first lower die, and the second machining die comprises a second upper die and a second lower die. The press machine device uses a press machine to press the deformed steel bar into a shape of the Chinese character 'ji', and is good in molding, high in accuracy, wide in applicable scope, simple in operation and high in work efficiency.

Description

technical field [0001] The invention relates to a hook mould, in particular to a mold for a press machine bent rebar steel several-shaped concrete embedded part. Background technique [0002] At present, there are often many accessories of various shapes and round steel hooks on steel structural members, which are convenient for safe construction. [0003] The conventional bending method of the existing screw-shaped concrete embedded parts is to bend by pyrotechnics. First, the rebar to be bent is heated red with fire and then bent. This method has high cost, low efficiency, and large error in shape and size. At the same time, existing presses usually form steel plates, but there is still a blank for forming rebars, because rebars are in line contact with planes, and point contacts with arcuate surfaces, and are easily deformed after being pressed. Contents of the invention [0004] The present invention aims at the deficiencies of the above-mentioned problems, and propos...
