Machining device for seal ring annular seats of pressure steam sterilizers

Abstract

The invention discloses a machining device for seal ring annular seats of pressure steam sterilizers and relates to medical pressure steam sterilizers. The machining device comprises a male die and a male die. The female die comprises a female die base, an annular outer female die body and a circular inner female die body, an annular molding groove is formed between the inner female die body and the outer female die body, an annular chute is arranged below the molding groove, the upper portion of the chute is communicated with the lower portion of the molding groove, an annular sliding block is placed in the chute, a hold-down ring matched with the molding groove is arranged on the upper side of the sliding block, and a compression spring is disposed between the lower side of the sliding block and the female die base. The male die comprises a circular pressurization base, a male die plate, an inner material pressing disk and an outer material pressing disk, wherein the outer material pressing disk is arranged on the outer side of the male die plate in a vertical sliding mode, a compression spring is disposed between the inner material pressing disk and the pressurization base, a connecting bolt capable of sliding vertically is arranged on the pressurization base, and the lower end of the connecting bolt is connected with the inner material pressing disk. The machining device has the advantages that the machining speed is high, the efficiency is high, the yield is up to 100%, the cost is low, and the normal production speed is not affected. Stainless steel annular plates can be cut by laser, the cutting time is short, and the efficiency is high.

Description

technical field [0001] The invention relates to a medical pressure steam sterilizer, in detail, it is a processing device for a pressure steam sterilizer seal ring seat with high processing speed, high efficiency, high yield and low processing cost. Background technique [0002] We know that pressure steam sterilizer is the most common sterilizer used by medical institutions to sterilize medical devices, dressings, glassware, solution culture medium, etc. When the pressure steam sterilizer is working, the sterilization chamber is filled with high-temperature and high-pressure steam, and a sealing ring is used to seal the sterilization chamber and the sealing door. The corresponding place is provided with a sealing ring seat (usually welded into one body), and a sealing ring is arranged in the sealing ring seat. The processing of the existing sealing ring seat is: cut a ring on the thicker stainless steel plate with wire cutting, and process the annular sealing ring on t...

AI Technical Summary

Problems solved by technology

In this processing method, the thickness of the stainless steel plate used generally needs to be 16mm-20mm according to the size of the sealing ring. The utilization rate of stainless steel is low and the cost is high; wire cutting a stainless steel ring requires 6-8 hours of processing time, which is long. High energy consumption and low efficiency; when using a lathe to process the ring-shaped sealing ring on the stainless steel ring to be embedded in the groove, it is necessary to use a lathe chuck to fix the stainless steel ring, and when the chuck is released after processing, the ring seat of the processed sealing ring is easy to Deformation and high scrap rate further increase the manufacturing cost and affect the normal production of the sterilizer due to low efficiency
