Middle hinge gasket bending mold for preventing workpiece wear

Abstract

The invention discloses a middle hinge gasket bending mold for preventing workpiece wear. The middle hinge gasket bending mold comprises a lower mold base, a lower cushion plate, a concave mold, an ejector block, a spring, a mold handle, an upper mold base, an upper cushion plate, a convex mold fixed base and a convex mold; the upper mold base and the lower mold base are connected through a guide component; the concave mold is mounted above the lower mold base through a fastening piece; the lower cushion plate is arranged between the concave mold and the lower mold base; the middle part of the concave mold is coated with the ejector block; the lower end of the ejector block is fixedly connected with the spring; the lower end part of the spring penetrates through the lower cushion plate to be fixedly connected to the lower mold base; the upper mold base fixedly connects the mold handle, the upper cushion plate and the convex mold fixed base in sequence through fastening pieces from top to bottom; the convex mold coats the middle part of the convex mold fixed base; the upper end surface of the concave mold is additionally connected with two positioning columns; the middle part of the upper end surface of the concave mold is V-shaped; and a wear resisting protection layer is arranged on the V-shaped surface. The middle hinge gasket bending mold for preventing workpiece wear effectively prevents the scratch of workpieces in the machining process to improve the finished product quality of the workpieces.

Description

technical field [0001] The invention relates to a mold structure used for processing hinge gaskets, in particular to a bending mold which can effectively prevent wear of workpieces in the bending process. Background technique [0002] The bending process is a stamping process that bends the blank into a certain angle and a certain shape of the workpiece through a mold and a press according to the shape of the part. attached figure 1 The middle hinge gasket is shown. This part is a typical V-shaped part. The shape and structure of the workpiece are relatively simple and symmetrical. It is usually mass-produced. This part mainly has two processing procedures: punching and bending. In the bending process, it is necessary to ensure that the surface of the bent part is clean and free of scratches, which is usually an important precision requirement item for the bent part. However, during the working process of the bending die in the prior art, due to friction between the workpie...

In the bending process, it is necessary to ensure that the surface of the bent part is clean and free of scratches, which is usually an important precision requirement item for the bent part. However, during the working process of the bending die in the prior art, due to friction between the workpiece and the surface of the die, or More or less, it will damage the surface of the curved parts, reduce the quality of the workpiece, and affect the shape and dimensional accuracy of the workpiece
