Embodiment 1

[0021] Draw a drawing of the rectangular seal according to the dimensions of the desired product (see figure 1 ), design a rectangular ring mold according to the drawings, and the height of the mold shall not be greater than that of the cutting equipment (please refer to Figure 4 ) in the width of the nylon column. Vulcanize the rectangular seal 1 that meets the drawings through the existing technology (please refer to figure 2 ), and then superimpose the thickness of the rectangular seal 1 to a certain height and put it into the rectangular sealing ring mold, and the whole heat vulcanization obtains the rectangular sealing ring (please refer to image 3 ), the rectangular sealing ring is put on the slit nylon column by gas propulsion, and finally by adjusting the equipment process parameters, the slitting equipment is used to slit the rectangular sealing ring to obtain a rectangular seal with an accuracy of ±0.05 tolerance accuracy.

[0022] It should be noted that the th...

Abstract

The invention provides a rectangular sealing part manufacturing method. The method includes the first step of drawing a drawing of a rectangular sealing part according to the required shape and dimensions of the part, the second step of designing a rectangular sealing ring mould according to the drawing, wherein the designed height of the mould is not allowed to be larger than the width of a nylon column of a slitter machine, the third step of conducting vulcanization to form the rectangular sealing parts according with the drawing, then overlaying the rectangular sealing parts to reach a certain thickness and placing the overlaid rectangular sealing parts into the rectangular sealing ring mould for integral vulcanization to obtain a rectangular sealing ring, and the fourth step of propelling the rectangular sealing ring through gas to enable the rectangular sealing ring to be arranged on the nylon column of the slitter machine in a sleeved mode, and slitting rectangular sealing ring through the slitter machine to obtain the rectangular sealing parts. The rectangular sealing part manufacturing method has the advantages that the manufacturing efficiency of the rectangular sealing parts is high, and the accuracy of the rectangular sealing parts can be effectively controlled.

Description

technical field [0001] The invention relates to a rectangular sealing element, in particular to a method for processing the rectangular sealing element. Background technique [0002] In the prior art, the rectangular seal adopts a single-cavity thermal vulcanization method to realize product shaping. In fixed equipment, the vulcanization temperature is between 160-200 degrees, and the material is vulcanized and shaped by a certain pressure and time, and the size is fixed, and the product is directly formed. , The single cavity production efficiency is low in the process. [0003] Chinese patent document CN201310220080.7, the application date was June 5, 2013, the patent name is a preparation method of ultra-low temperature resistant U-shaped sealing ring, which discloses a method for preparing ultra-low temperature resistant U-shaped sealing rings by slitting and step-by-step hot pressing. The method of preparation of the sealing ring. However, there is no report about the...
