Automatic forming method and device for rubber sealing ring blank

Abstract

The invention relates to the technical field of rubber sealing ring blank forming, in particular to an automatic rubber sealing ring blank forming method and device.A cutting blade is fixedly connected to the surface of a blank forming assembly, a second equipment body is fixedly connected to a sliding table module, and a second supporting rod is fixedly connected to the surface of the second equipment body; the inner side surface of the second supporting rod is fixedly connected with a blank box, and the tail end of the long blank strip is fixedly connected with a blank thread shaft. The device has the advantages that the automation degree is high, blank strips conveyed from the blank spool pass through the guide wheels and the guide grooves and are automatically pressed into rings through the combined action of the blank forming assembly and the cutting blade, feeding is conducted in a continuous blank strip introduction mode, automatic forming of the blank rings is achieved through the action of the automation assembly, and the production efficiency is improved. Except that the blank long strip of the blank bobbin is used up and the blank bobbin is replaced, the other processes are all completed by the machine, and the automation rate is high.

Description

technical field [0001] The invention relates to the technical field of rubber sealing ring blank forming, in particular to an automatic forming method and a device for a rubber sealing ring blank. Background technique [0002] The production of rubber sealing rings mostly adopts the molding vulcanization process. After placing the produced rubber blank ring in the mold cavity, the product is molded and vulcanized according to the process parameters. In the prior art, the molding methods and advantages and disadvantages of the rubber blank ring are mainly: [0003] 1. The whole circle forming process of the blank: cutting machine cutting process, this process is to compound the rubber blank into a thin sheet, place it on the working table of the cutting machine, and plan the cutting path for the cutting machine. The advantages of this process are: the molding speed is fast, and the degree of flexibility of the billet molding is high. The disadvantage is: in order to avoid was...

AI Technical Summary

Problems solved by technology

[0003] 1. Billet full circle forming process 1: cutting machine cutting process. This process is to make rubber blanks into thin sheets after compounding, and place them on the working table of the cutting machine. By planning the cutting path for the cutting machine, cut out all the parts on the sheet. For rubber blanks that require size, the advantages of this process are: fast forming speed and high degree of flexibility in blank forming. The disadvantage is: in order to avoid wasting the remaining leftovers, it is usually re-formed into thin sheets and then re-cut. This will inevitably cause some rubber materials to be repeatedly compounded, so as to affect the performance of the apron;

[0004] 2. Billet full-circle forming process 2: Extrude into a tube and then cut into a ring. This process is to place the rubber billet on the rubber extruder after compounding. The billet is extruded from the die of the extruder into a tube. The extruded rubber tube is cut into rings by a high-speed rotating cutter. The advantages of this process are: fast forming speed and stable forming. The disadvantage is that the degree of flexibility is relatively low. If you need to form rubber rings of different sizes, It is necessary to stop the machine to replace the corresponding die;

[0006] The advantage of this process is: a high degree of flexibility, and it can be overlapped at will according to the required size of the apron. The disadvantages are:

[0007] (1) The process is mainly manual operation, and the molding efficiency is not high;

[0008] The quality stability of the billet ring fluctuates greatly, which may easily cause the thickness of the flash after vulcanization of the rubber ring to be unstable, and then lead to the fluctuation of the size of the rubber ring after molding and vulcanization, and there is a certain degree of quality hidden danger
