Description

Technical Field

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

[0002] In modern industrial production, hydraulic cylinders are widely used. As various industries have increasingly higher requirements for the processing size and appearance of telescopic steel tubes of hydraulic cylinders, tube shrinking is a common and important process in the field of steel tube processing. However, traditional tube shrinking machines have many inconveniences in the process of taking and placing steel tubes. Manual placement of steel tubes is not only time-consuming and labor-intensive, but also prone to position deviations. It is also difficult to ensure the accuracy of the position of the steel tubes, thereby affecting the stability and quality of the tube shrinkage. At the same time, after the tube shrinkage is completed, it is also difficult to remove the steel tube. It is necessary to open the fixing device and then perform laborious manual operation, which is labor-intensive and inefficient. In addition, the processed steel tubes need to be collected and manually placed for transportation, which is not convenient enough. Utility Model Content
