Description

Technical Field

[0001] The utility model relates to the technical field of tube shrinking machines, in particular to a tube shrinking machine which is convenient for taking and placing steel tubes. Background Art

[0002] The tube shrinking machine is a hydraulic fully automatic tube end processing machine that expands and shrinks the end face of the tube fitting under normal conditions and is controlled by an integrated control touch display screen. By replacing the mold, the tube fitting can be expanded, shrunk, bulged, and upset. The tube shrinking machine usually includes an oil tank, a bed, a slide, a main oil cylinder, a mold core rod, a limit oil cylinder, a clamping oil cylinder, a clamping mold and an axial positioning oil cylinder, an axial positioning angle iron and other main parts. In order to improve the tube shrinking efficiency, the tube is shrunk at both ends of the tube fitting. Generally, the utilization rate of the double-head tube shrinking machine is higher. After searching, the patent with the announcement number CN116174595A discloses a double-head tube shrinking machine. By providing a first fixed block, a movable block and a feeding mechanism, the feeding mechanism will be processed. The pipe fittings are transported to the clamping block, and then the first cylinder and the second cylinder are started to push the movable blocks to move closer to each other. The tube shrinking molds on the two movable blocks swallow the two ends of the pipe fittings into the inside respectively, and then the tube shrinking molds are started to shrink the pipe fittings, thereby completing the purpose of shrinking both ends of the pipe fittings at the same time, saving the tube shrinking time. At the same time, the feeding mechanism is used to feed the pipe fittings, eliminating the manual feeding steps, which not only improves the feeding speed but also reduces the operating risks of the staff. However, the unloading process still requires manual grabbing. For this reason, a tube shrinking machine that is convenient for automatic and precise picking and placing of steel pipes, as well as for preparing and unloading materials while shrinking the pipes, is designed to improve the tube shrinking efficiency and the picking and placing safety.
