Embodiment Construction

[0006] refer to figure 1 , which includes an upper die 1 and a lower die 2, the cutout 3 of the upper die is in the shape of an arc, the lower die 2 is fixed on the worktable of the punch press, and the upper die 1 is connected to the drive push rod of the punch press.

[0007] Working principle: This invention is mainly aimed at the trapezoidal groove processing of channel steel tie rods, changing the traditional processing method of gas cutting, and implementing one-time stamping forming; the one-time forming mold of channel steel tie rod punching machine is mainly composed of upper and lower molds, and the lower mold is fixed on the workbench of the punching machine , the upper die is connected to the drive push rod of the punch press; the cutout part of the upper die is designed in an arc shape instead of a plane. After a part of the workpiece is cut, it is all lowered into the shear, which can greatly reduce the tonnage requirements of the punching machine.

Abstract

The invention relates to the technical field of U-steel pull rod manufacturing, in particular to a one-time forming die for U-steel pull rod manufacturing. The one-time forming die comprises an upper die and a lower die, wherein the notch part of the upper die is in an arc shape; the lower die is fixed to a worktable of a punching machine; the upper die is connected to a transmission push rod of the punching machine. The one-time forming die has the characteristics of being low in cost of manufactured products, convenient to use, free of any dangerousness, high in production efficiency and the like. The products manufactured by the one-time forming die in a punching mode are prefect in shape and stable in quality. In addition, as a certain improvement of the upper die of the punching die, the notch part of the upper die is made to be in the arc shape, so that the upper die and the lower die carry out linear cutting instead of planar cutting in the punching process, and the requirement for the tonnage of the punching machine matched with the die is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of manufacturing channel-shaped tie rods, in particular to a primary molding die for manufacturing channel-shaped tie rods. Background technique [0002] At present, when traditionally processing and manufacturing channel steel tie rods, the processing technology is to use oxygen and acetylene to cut and gas cut to obtain the corresponding shape. The disadvantages of this process are that there are many procedures and the appearance of the processed products is not beautiful; the processing cost is high, the labor force of the workers is large, and the production efficiency is low; there are also high requirements for the technical proficiency of the operators; there are certain risks in the processing process. . Contents of the invention [0003] The object of the present invention is to provide a one-time molding die for channel steel tie rod manufacturing, which has the characteristics of low cost, con...
