An inner tube core remover for hydraulic tube production

Abstract

The invention relates to the technical field of steel pipe forming equipment, and discloses an inner pipe core remover for hydraulic pipe production, including a frame. The inner tube core remover for hydraulic tube production is installed through the negative pressure chamber that continues to be opened in the middle of the inner hole of the clamping die and is installed in conjunction with the air extraction motor and electromagnetic valve, and works intermittently and alternately between the air extraction motor and the electromagnetic valve. The air pressure in the negative pressure chamber is constantly changing, so that the expansion and contraction of the rubber hose is in a beating state, so that the high-pressure medium between the rubber core and the rubber hose can be pumped to a deeper level, and the filling efficiency of the high-pressure medium is promoted. Under the action of the hydraulic pump filling the high-pressure medium, the deformation bag expands, pushes the telescopic sleeve to move up, and drives the skateboard to move up, so that the rubber hose pushed by the skateboard has an upward bulge effect, and the negative pressure generated by the suction motor works. Under the joint action of filling high-pressure media, it is easier to generate gaps, and the resulting gaps are larger, further increasing the degree of negative pressure expansion.

Description

technical field [0001] The invention relates to the technical field of steel pipe forming equipment, in particular to an inner pipe core remover for hydraulic pipe production. Background technique [0002] In recent years, with the continuous development of industries such as automobiles, petroleum, coal mines, chemicals, and machinery, the application of steel wire braided rubber hoses has become increasingly widespread. At present, the production methods of steel wire braided hoses mainly include coreless method, hard core method and soft core method. , The coreless method often has dimensional instability and poor adhesion between the rubber material and the steel wire layer, so it is gradually eliminated. In the manufacturing process of the cored method, the rubber core needs to be pulled out, and a core remover is needed to solve it. [0003] In the existing inner tube core stripping machine for hydraulic tube production, firstly, the hydraulic tube to be cored off is f...
