Description

Technical Field

[0001] The utility model relates to a press, in particular to a hydraulic press for safely pressing oil seals. Background Art

[0002] In the prior art, a hydraulic press in the assembly workshop for producing hydraulic pumps is used for pressing oil seals. In this process, workers need to place the oil seal parts inside the hydraulic press and then start the hydraulic press for pressing. There are relatively large potential safety hazards in the process of the hydraulic press; in addition, due to the size limitation of the hydraulic press, it is only applicable to the processing of parts within a certain size range, and the applicable range is relatively small. Summary of the Utility Model

[0003] In order to solve the problems of the prior art, the utility model provides a hydraulic press for safely pressing oil seals, which can greatly improve the safety of the oil seal pressing process of the hydraulic press, is simple and convenient to operate, has a low transformation cost, and can be applicable to the processing of various different models of products.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A hydraulic press for safely pressing oil seals includes a frame base. A controller and a hydraulic system are arranged inside the frame base. Four corners above the frame base are connected to a top bracket through hydraulic rods. A high-pressure pump is arranged at the center of the top bracket, and transparent baffles are arranged around it. The high-pressure pump and the hydraulic rods are respectively communicated with the hydraulic system through oil circuits. A replaceable base module is arranged on the frame base below the pressing head of the high-pressure pump, and the base module is fixed in a fixed groove of the frame base through a locking mechanism.

[0006] A safety baffle is arranged in front of the frame base. The safety baffle is hinged to the front edge of the frame base. A U-shaped notch is arranged at the center of the safety baffle for accommodating the base module after being laid down. A safety button is arranged on the frame base inside the safety baffle. The safety button is electrically connected to the controller and is used to control the opening and closing of the circuit of the whole hydraulic press.

[0007] A safety light curtain is arranged between the front edge of the top bracket and the front edge of the frame base. The safety light curtain is electrically connected to the controller and is used to control the opening and closing of the circuit of the whole hydraulic press.

[0008] The locking mechanism includes an upper surrounding ring and a lower surrounding ring. One ends of the upper surrounding ring and the lower surrounding ring are hinged together and fixed on the frame base, and the other ends are fixed through a locking nut. Rubber layers are arranged on the inner side surfaces of the upper surrounding ring and the lower surrounding ring.

[0009] The beneficial effects brought by the technical solution provided by the utility model are:

[0010] 1. The utility model replaces the original column bracket with a hydraulic rod, enabling the processing height of the entire hydraulic press to be adjusted, thereby improving the limitation of the processing dimensions of the components of the hydraulic press.

[0011] 2. The replaceable base module can replace different modules according to the components of different sizes to be processed, so as to match the product for fixed pressing.

[0012] 3. The design of the safety baffle serves the purpose of a safety switch. Only when the side of the safety baffle is laid down and the safety button is pressed can the entire electric control system be powered on, avoiding the insecurity caused by directly installing the workpiece to be processed in the live state.

[0013] 4. The safety light curtain further realizes the control of the power-on switch, and its priority is lower than that of the safety button. Its function is that during the processing, if an object invades the processing range of the hydraulic press, it will be sensed by the sensor of the safety light curtain, triggering the circuit and directly cutting off the power, improving safety.

[0014] 5. The locking mechanism can ensure the firm fixation of the base module, facilitating the pressing process. BRIEF DESCRIPTION OF THE DRAWINGS
