Description

Technical Field

[0001] The present invention belongs to the technical field of machine tool protection, and particularly relates to a flexible bellows protective cover and a manufacturing method thereof. Background Art

[0002] The bellows protective cover is a kind of machine tool protective cover. The bellows protective cover includes an outer protective member made of three-proof cloth or rubber material, and a skeleton (a plate made of PVC or other materials) for supporting and stabilizing is installed in each group of outer protective members.

[0003] At a certain temperature (100°), by means of a special solvent (specific glue), the special solvent is dissolved at high temperature, and the internal skeleton and the external outer protective member are firmly bonded / welded together to form a bellows protective cover; or

[0004] The high-frequency welding and heat-sealing process is adopted to firmly weld the internal skeleton and the external outer protective member together. The instantaneous temperature of high-frequency welding can reach several hundred degrees. Utilizing the ultra-high temperature, the fabric and the skeleton are instantaneously dissolved and fused together;

[0005] The special solvent (glue) is expensive and the process is complex, resulting in a long production time and high production cost. Moreover, when using the high-frequency welding and heat-sealing process, the high temperature will cause thermal deformation of the outer protective member (three-proof cloth or rubber material) and the skeleton (a plate made of PVC or other materials). Although it looks relatively strong in the short term, it is easy to come apart after being used for a period of time.

[0006] In view of this, how to solve the defects existing in the above technical solutions has become one of the problems to be urgently solved in the technical field of machine tool protection. Summary of the Invention
