Embodiment Construction

[0023] based on the following Figure 1 to Figure 4 , specifically explain the preferred embodiment of the present invention.

[0024] Such as figure 1 As shown, the present invention provides a U-shaped groove forming die, which is arranged on a numerical control bending machine, and the U-shaped groove forming die includes:

[0025] Upper mold 1, which has a U-shaped outer profile;

[0026] Two lower mold assemblies, the lower mold assembly includes a base 3 and a lower mold 2, the top of the lower mold 2 has a right angle groove 201, the inner side of the lower mold 2 is located below the upper mold 1, the The bottom and side contours of the lower mold 2 are semicircular body 202, the top contour of the base 3 matches the semicircular body 202 outer contour of the lower mold 2, and the base 3 is used to accommodate the lower mold 2, The lower mold 2 can be relatively rotated on the base 3;

[0027] Back-moving spring 5, one end of which is fixed on the base 3, and the o...

Abstract

According to a U-shaped groove forming mold and method, the width of a U-shaped groove can be adjusted differently according to requirements through an adjusting gasket, and a material can be conveniently and rapidly returned through a spring, so a large amount of labor is saved, and the cost is reduced; and one-time forming is achieved without additionally arranging other equipment, so the consistency of the height of a product can be guaranteed, and the productivity is greatly improved.

Description

technical field [0001] The invention relates to a U-shaped groove forming mold and a forming method. Background technique [0002] In electronics, automobiles, motors, electrical appliances, instruments, meters, home appliances, communications and military products, 60% to 80% of the parts are formed by stamping and bending. Among them, bending is the most typical and important forming tool for sheet metal parts. The high precision of parts bent and formed by molds is unmatched by other processing and manufacturing methods. Mold largely determines product quality, benefit and development capability. [0003] The two sides of the boom of the marine crane are reinforced by U-shaped grooves. There are about ten types of U-shaped grooves used, which are large and small. Different molds are used to manufacture U-shaped grooves of different specifications, which is time-consuming and labor-intensive. Costs are high. Contents of the invention [0004] The purpose of the presen...
