Description

technical field [0001] The invention relates to a vacuum automatic rubber gasket cutting machine, which belongs to the technical field of machinery. Background technique [0002] At present, due to technical problems, the existing cutting machine molding equipment can only produce a single part, and each part needs to trim the waste edge, and the multi-cavity part size is caused by the pressure difference of the vulcanization equipment plate surface and the cooling shrinkage after vulcanization. Poor, the uniformity of product quality cannot be guaranteed, the sealing quality of rectangular seals has declined due to mold aging problems, and low efficiency and many other problems lack professional production automation equipment. Due to the low production efficiency of the existing rectangular seals and rubber gaskets, because each piece has to be trimmed, and due to the problem of the surface area of ​​the vulcanization equipment, the single-mode output is not high, the prod...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing related equipment cannot realize automatic loading and unloading of the processed parts, and the processed parts are completely manually loaded and unloaded

Since the processed product is a rubber product with a certain length, elasticity, softness, and bending characteristics, the manual installation process is complicated and difficult to install smoothly. Sometimes auxiliary tools are required for installation, resulting in low production efficiency.

[0005] 2. The clamping of the workpiece in the existing related equipment is based on the friction between the interference size of the tooling and the workpiece. This process is backward

Once the workpiece slips during the processing process, it will inevitably cause the workpiece to be scrapped, resulting in unnecessary losses

[0006] 3. The processed parts of the existing related equipment on the market are all removed from the tooling one by one by hand after cutting. Due to the interference fit of the tooling, it is time-consuming and laborious to remove the processed parts

[0007] 4. The existing related equipment on the market is manually fed and processed, which cannot guarantee the uniformity of the quality of the processed parts, and the conditions for product quality to be affected by human factors are increasing.

[0008] 5. The knives used in the existing related equipment on the market are usually ground from white steel knives or tool steel. Since the thinnest such knives on the market are 3mm, they will still have a certain thickness even after grinding. The auxiliary cutting edge rubs against the product, resulting in rough processing surface of the product, it is difficult to have a high finish, and the processing surface is not smooth enough

At the same time, the tool will squeeze the surface to be processed, resulting in increased frictional resistance, causing the product to stop, friction and heat generation for a long time will make the tool anneal and shorten the service life of the tool

The product stops and the friction between the tooling generates heat, causing the product and the tooling to burn out
