Problems solved by technology

[0004] However, in this manufacturing method, at least four forgings are required. Since the molds for each forging are different, multiple machines are required to process one type of automobile gasket, and there are many processing procedures, resulting in manpower and machine costs. increase; and, when it is forging for the second time, it is still necessary to punch out the inner diameter part, and there is still a phenomenon of material waste
Therefore, the production cost of this manufacturing method is still high

Embodiment 1

[0036] A kind of manufacturing method of the gasket that material is 40Cr steel, comprises the following steps:

[0037] a. Obtain a ring-shaped workpiece 1: Clamp the steel pipe on the lathe spindle, cut the steel pipe to the required length with a turning tool, and obtain a ring-shaped workpiece 1 to be processed; after cutting, there are burrs 2 remaining at both ends of the workpiece 1 ;

[0038] Thereafter, the ring-shaped workpiece 1 to be processed is deburred 2, specifically, the end of the workpiece 1 is internally chamfered with a lathe.

[0039] As a solution of the deburring 2, only one side of the workpiece 1 is chamfered and deburred during the deburring process.

[0040] As another solution for deburring, both sides of the workpiece 1 are chamfered and deburred during the deburring process.

[0041] b. After the workpiece 1 is deburred, perform annealing treatment: perform annealing treatment on the annular workpiece 1; first heat the annular workpiece 1 sever...

Embodiment 2

[0055] A kind of manufacturing method of the gasket that material is 40Cr steel, comprises the following steps:

[0056] a. Obtain a ring-shaped workpiece 1: Clamp the steel pipe on the lathe spindle, cut the steel pipe to the required length with a turning tool, and obtain a ring-shaped workpiece 1 to be processed; after cutting, there are burrs 2 remaining at both ends of the workpiece 1 ;

[0057] Thereafter, the ring-shaped workpiece 1 to be processed is deburred, specifically, the two ends of the workpiece 1 are chamfered with a lathe.

[0058] b. After the workpiece 1 is deburred, perform annealing treatment: perform annealing treatment on the annular workpiece 1; first heat the annular workpiece 1 several times, and heat each time to the set temperature within the set time and The set temperature reached after each heating is gradually increased; then the workpiece 1 after several times of heating is cooled several times, and each cooling is cooled to the set temperatu...

Embodiment 3

[0071] A kind of manufacturing method of the gasket that material is 40Cr steel, comprises the following steps:

[0072] a. Obtain a ring-shaped workpiece 1: Clamp the steel pipe on the lathe spindle, cut the steel pipe to the required length with a turning tool, and obtain a ring-shaped workpiece 1 to be processed; after cutting, there are burrs 2 remaining at both ends of the workpiece 1 ;

[0073] Thereafter, the ring-shaped workpiece 1 to be processed is deburred, specifically, the two ends of the workpiece 1 are chamfered with a lathe.

[0074] b. After the workpiece 1 is deburred, perform annealing treatment: perform annealing treatment on the annular workpiece 1; first heat the annular workpiece 1 several times, and heat each time to the set temperature within the set time and The set temperature reached after each heating is gradually increased; then the workpiece 1 after several times of heating is cooled several times, and each cooling is cooled to the set temperatu...

Abstract

The invention provides a gasket manufacturing method and belongs to the technical field. According to the method, the problem that the cost of a gasket manufactured through an existing gasket manufacturing method is higher is solved. The gasket manufacturing method comprises the following steps of a, acquiring an annular workpiece, namely cutting needed length from a tubular raw material to obtain the to-be-machined annular workpiece; b, performing annealing, namely annealing the annular workpiece; c, performing cold extrusion, namely performing cold extrusion on the workpiece at one time to form a gasket in a needed shape; d, performing thermal treatment, namely performing thermal treatment on the gasket which is formed by extrusion. According to the gasket manufacturing method provided by the invention, a tube material is directly cut and is subjected to one-time cold extrusion forming, the process is simpler, and the raw material is not wasted, so that the production cost of an automobile gasket is lower.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a manufacturing method, in particular to a gasket manufacturing method. Background technique [0002] In the manufacturing process of automobile gaskets, the traditional method is to use a punching machine to complete the finished material on a steel plate. Although the processing procedure is relatively simple in this processing method, there are many other materials, resulting in a serious waste of materials. [0003] In view of this problem, the Chinese Invention Patent Application Publication (publication number: CN1453097A, publication date: 2003.11.5) discloses a manufacturing method of a gasket, which includes the following steps: 1. Calculate the weight of the finished product according to the size requirements; 2. Cut materials of equal weight from steel bars (bars); 3. Carry out the first forging, press the above materials into appropriate sizes; 4. Carry out the second...
