Description

Technical Field

[0001] The utility model relates to the technical field of single-column hydraulic presses, in particular to a self-adaptive pressure-regulating single-column hydraulic press. Background Art

[0002] Single-column hydraulic presses are mainly used for processes such as stretching, forming and pressing of metal products, as well as the correction of shaft parts and the press-fitting of sleeve parts. In order to improve the yield rate of hydraulic processing, the existing single-column hydraulic presses adopt an adaptive pressure-adjustable design, which can effectively avoid defective products caused by excessive or insufficient pressure in processing processes such as stretching, forming and pressing.

[0003] In actual applications, in the auxiliary pressing of sleeve-type workpieces, although the existing equipment can avoid the quality impact of deformation damage to the workpiece caused by large pressure through internal pressure detection, in the auxiliary pressing of sleeve bearings, the pressing distance of the sleeve bearings will vary with the different types of workpieces.

[0031] The working principle and use process of this utility model: When the device is actually used:

[0032] When the equipment is working, the shaft sleeve that needs to be assisted in the installation of the bearing is placed on the hydraulic lower die 4 and is directly opposite to the position below the hydraulic upper die 11. Then the infrared distance measuring module 29 measures the distance of the shaft sleeve placed on the hydraulic lower die 4 through the distance measuring through slot 27 opened on the hydraulic upper die 11. Combined with the known distance to the hydraulic lower die 4, the height data of the shaft sleeve itself can be obtained and the data is fed back to the control panel 5 in real time. After completing the distance measurement, the bearing is placed in the shaft sleeve installation position, and then the hydraulic cylinder 3 is started through the control panel 5, so that the hydraulic head 10 drives the hydraulic upper die 11 to press down. When the hydraulic upper die 11 contacts the bearing and generates downward pressure, the bottom end of the hydraulic lower die 4 is also slightly pressed down and contacts the pressure sensor 18. At this time, the pressure sensor 18 can detect the working pressure in real time. When the detected pressure value reaches the yield strength pressure value of the bearing and sleeve constituent material, the control end will directly send an instruction through the control panel 5 to control the hydraulic cylinder 3 to stop output, so as to avoid damage to the bearing sleeve caused by excessive pressure.

[0033] Compared with traditional hydraulic equipment with built-in pressure detection, this utility model reduces the equipment cost by placing the pressure detection equipment externally and separating it from the hydraulic equipment, and also facilitates the inspection and maintenance of the pressure detection equipment. At the same time, the equipment also has the adaptive adjustment function of the hydraulic output working distance, which greatly improves the working efficiency of the equipment itself.
