High-strength bolt cold heading equipment and cold heading process

Abstract

The invention discloses high-strength bolt cold heading equipment and a cold heading process. The high-strength bolt cold heading equipment comprises a fixing frame, a cold heading machine is fixedlyconnected to the top of the fixing frame, a discharging plate is fixedly connected to the right side of the top of the fixing frame and located on the right side of the cold heading machine, a first supporting frame is fixedly connected to the left side of the bottom of the fixing frame, and the right side of the bottom of the fixing frame is fixedly connected with a second supporting frame. Through cooperative use of the fixing frame, the cold heading machine, the discharging plate, the first supporting frame, the second supporting frame, the bottom plate, a box body, a motor, a rotating rod,a stirring rod, a bracket, a filtering plate, an oil pump, a first connecting pipe, a second connecting pipe, a spray head and an oil discharging pipe, bolts can be effectively cleaned after cold heading, the cleaning effect is improved, and good working conditions are provided for subsequent processing; and meanwhile, the bolts produced through the process can reduce the phenomena of delayed fracture and fatigue fracture,fracture is not prone to occurring in the using process, the connection is reliable, and the service life of the bolts is prolonged.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to high-strength bolt cold heading equipment and a cold heading process. Background technique [0002] A bolt is a mechanical part, a cylindrical threaded fastener with a nut, a type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten and connect two For parts with holes, this connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, the bolt connection is a detachable connection. According to the force of the connection, it is divided into ordinary and For reaming holes, according to the shape of the head, it is divided into hexagonal head, round head, square head, countersunk head, etc. Among them, the hexagonal head is the most commonly used, and the countersunk head is generally used in places where connections are required. Bolts In daily life and industrial ...

Problems solved by technology

[0003] The purpose of the present invention is to provide a high-strength bolt cold heading equipment and cold heading process, which has the advantages of improving bolt strength and convenient cleaning, and solves the problem that the current processing method generally adopts turning method to form, and its strength is often difficult to guarantee. When the tensile strength exceeds a certain value, it is easy to cause delayed fracture and fatigue fracture in places where the gaps are concentrated, such as the transition between the rod and the head or the root of the thread, which will seriously affect the quality of the project. In severe cases, it will cause safety problems due to insufficient connection strength. The problem of accidents
