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

A method for processing and manufacturing a rectangular seal. First draw a drawing of the rectangular seal according to the shape and size required by the product, and then design a rectangular sealing ring mold according to the drawing. The height of the mold design must not be greater than the width of the nylon column of the slitting equipment. Produce a rectangular seal that meets the drawings, then superimpose the thickness of the rectangular seal to a certain height and put it into the rectangular seal ring mold, heat vulcanize the whole to obtain a rectangular seal, and finally use the gas to push the rectangular seal into the nylon that is set on the slitting equipment On the column, the rectangular sealing ring is cut by a slitting device to obtain a rectangular sealing member; the advantage of the present invention is that the manufacturing efficiency of the rectangular sealing member is high, and the precision 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 is June 5, 2013, the patent name is a preparation method of an ultra-low temperature resistant U-shaped sealing ring, which discloses a method for preparing an ultra-low temperature resistant U-shaped sealing ring through slitting and step-by-step hot pressing. The method of preparation of the sealing ring. However, there is no report ...
