Problems solved by technology

[0003] The conventional bending method of the existing round steel hook is to bend by pyrotechnics. First, the round steel 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, the existing presses usually form steel plates, but there is still a blank for forming round steel, because the contact between round steel and the plane is line contact, and the horizontal contact with the arc surface is point contact, and it is easy to deform after being pressed.

Abstract

The invention relates to a press machine device for bending a U-shaped round steel fillet hook. The device comprises an upper die and a lower die, the upper die comprises an upper die body, and an inner clamped shape and a U-shaped puncher pin with a straight fillet belt are arranged on the upper die body. The lower die comprises a lower die body, a U-shaped support frame matched with the puncher pin is arranged on the lower die body, and a lower die rotation shaft is arranged on two opening ends of the U-shaped support frame. The press machine device for bending the U-shaped round steel fillet hook is used in a press machine to bend round steel through the die to achieve purposes of being 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 mold for forming a hook, in particular to a mold for bending a U-shaped round steel hook for a press. 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 round steel hook is to bend by pyrotechnics. First, the round steel 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, the existing presses usually form steel plates, but there is still a blank for forming round steel, because the contact between round steel and flat surface is line contact, and the horizontal contact with circular arc surface is point contact, which is easy to deform after being pressed. Contents of the invention [0004] The present invention aims at the deficiencies of ...
