One-time forming bolt preparation component and forming method thereof

Abstract

The invention discloses a one-step molded bolt preparation assembly and a one-step molded bolt molding method, and belongs to the technical field of preparation of high-quality steel in metal materials in novel materials. The one-step molded bolt preparation assembly comprises a pair of stamping dies in a preset shape and size, a pair of clamping hydraulic cylinders and a ring cutter driving device; grooves matched with a bolt head, a screw and a gasket are formed in the stamping dies; the clamping hydraulic cylinders each comprises a hydraulic cylinder fixed end and a hydraulic cylinder movable end which are arranged in a slide fit mode, and the hydraulic cylinder movable ends are each connected with a fixture matched with the screw; a ring cutter head of which the radius is consistent with the diameter of the screw is detachably connected to the tail end of the ring cutter driving device; and the ring cutter driving device is used for driving the ring cutter head to do linear reciprocating motion. According to the one-step molded bolt preparation assembly, a billet is stamped into a stamping part integrating the bolt head, the screw and the gasket through equipment such as the hot stamping dies, the gasket is cut down from the stamping part through the ring cutter, and finally the screw portion is cut with a thread cutter head to form a thread texture. According to the one-step molded bolt preparation assembly and the one-step molded bolt molding method, the cost and the material consumption can be reduced, and the problem that the gasket and the screw are not closely matched is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, belongs to the technical field of high-quality steel preparation in metal materials among new materials, and specifically refers to a one-time forming bolt preparation component and a forming method thereof. Background technique [0002] Such as Figure 5 As shown, a group of bolts in the prior art includes a bolt head 2, a screw rod 3 and a gasket 4; wherein the bolt head 2 and the screw rod 3 are fixedly connected as a whole, and the gasket 4 is an annular gasket, and the gasket The inner hole of 4 is compatible with screw rod 3, and the outer diameter of gasket 4 is slightly larger than the diameter of bolt head 2. In the prior art, two parts, the integrated part consisting of the bolt head 2 and the screw rod 3 and the gasket 4, are generally manufactured separately. Such a manufacturing method not only has high cost and high material consumption, but also has the problem that t...
