Description

Technical Field

[0001] The utility model relates to the technical field of gasket production, in particular to a gasket production device. Background Art

[0002] Engine high-strength gasket is a high-strength, high-performance gasket, usually made of high-strength metal materials such as steel, stainless steel, titanium alloy, nickel-based alloy, etc. It has good elasticity and corrosion resistance, and can withstand static loads, dynamic loads or vibration loads. During the production process of this gasket, the material needs to be placed in a stamping die, and then the die is pressed on the material using mechanical or hydraulic force to form the required gasket shape. In the existing patent application with application number CN201921551990.2, a gasket stamping device is proposed, in which the punch is driven downward by a hydraulic cylinder, and the stamping forming of the gasket is completed with the cooperation of the lower cutter head, the punching groove and the waste hole, thereby reducing the processing steps and improving the work efficiency. The stamped gasket is driven to rise with the cooperation of the reset spring and the ejector ring, and the push plate is pushed out by the pneumatic cylinder, and the gasket is pushed into the feed chute and falls into the collection box for collection. The generated waste falls into the waste box through the waste hole, which is convenient for centralized processing, reduces the labor intensity and increases the safety. However, in the process of gasket stamping, a large noise will be generated. Due to the lack of noise reduction structure, the noise generated is easy to damage the hearing of the surrounding staff, so it needs to be improved. Utility Model Content
