Embodiment 1

[0042] In the present embodiment, using the method of the present invention, the rectangular rubber cylinder 2 with a wall thickness of 1.9 mm and external dimensions of 213 mm in length, 64 mm in width and 45 mm in height is cut and processed into 8 rubber rectangular rings with a height of 5 mm. The steps are as follows:

[0043] 1) Process the rectangular rubber cylinder 2;

[0044] 2) Turn the rectangular rubber tube 2 over so that the inner wall becomes the outer wall;

[0045] 3) Put the inverted rectangular rubber tube 2 on the circular nylon inner liner 3 with an outer diameter of 188mm;

[0046] 4) Clamp the nylon lining 3 onto the lathe;

[0047] 5) start the lathe to make the nylon lining 3 with the rectangular rubber tube 2 rotate at a speed of 2500 rev / min;

[0048] 6) The moving blade 4 cuts the rectangular rubber tube 2 into 8 rectangular rubber circles.

[0049] Thereby the size of processing is wall thickness: 1.9mm, external dimension is: length 213mm, wid...

Embodiment 2

[0051] The difference between embodiment 2 and embodiment 1 is that the outer diameter of the circular nylon lining 3 in embodiment 2 is 185.2mm, and the stretching amount of the circumferential direction of the rectangular rubber tube 2 is 5% at this moment; The cutting equipment is a cutting machine.

Embodiment 3

[0053] The difference between Example 3 and Example 1 is that the outer diameter of the circular nylon lining 3 in Example 3 is 194 mm, and the stretching amount of the rectangular rubber tube 2 in the circumferential direction is 10%.

Abstract

The invention belongs to the field of cutting machining methods for rubber rings and discloses a cutting machining method for rectangular rubber rings, which comprises the following steps of 1) machining a rectangular rubber barrel; 2) turning the rectangular rubber barrel, and turning the inner wall into the outer wall; 3) sleeving the turned rectangular rubber barrel on a round nylon lining; 4) clamping the nylon lining on a fixture of rectangular ring cutting equipment; 5) starting the cutting equipment to enable the nylon lining where the rectangular rubber barrel is sleeved to rotate in high speed; and 6) moving blades on the cutting equipment to cut the rectangular rubber barrel into a plurality of rectangular rubber rings. The cutting machining method turns the rectangular rubber barrel and sleeves the rectangular rubber barrel on the nylon lining to be cut and machined, thereby effectively removing four corners of the rectangular rubber barrel, resolving the problems that the nylon lining is untight in combining, cutting faces incline, and size fluctuation is large, and obviously improving machining accuracy of sizes of the rectangular rubber rings.

Description

technical field [0001] The invention relates to a cutting and processing method of a rubber ring, more specifically to a flipping cutting and processing method of a rectangular rubber ring. Background technique [0002] Rubber rings are widely used in various fields of modern industry. They can play the role of waterproof, shockproof and sealing. The traditional rubber rings mainly have the following methods: 1. Stamping type. Manual stamping and cutting on the raw materials, this is the most primitive way, its work efficiency is extremely low, the waste of raw materials is quite serious, and the waste cannot be recycled and reused, and more than 200 rubber rings can be cut per hour; 2. Lathe processing , which is to place the tubular rubber tube on the lathe for processing. This method must require high-level skilled workers to assist in the completion, but this single-tube processing method is still inefficient, the product tolerance is large, and the straight-line distanc...
