Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hydraulic press technology, and specifically relates to an auxiliary feeding mechanism for a hydraulic press. Background Technology
[0002] A hydraulic press is a machine that uses Pascal's principle and a liquid as the medium. Hydraulic presses include valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses. Hydraulic presses usually require a feeding mechanism for auxiliary feeding during use.
[0003] A search of publication number CN 218966252 U reveals an auxiliary feeding mechanism for a hydraulic press. Its key technical feature is that, through the use of a sliding frame, slotting, and scraper, it can quickly assist in cleaning the top of the base after the hydraulic press has been used, pushing residual waste to both sides to avoid the safety hazards caused by manual cleaning by operators. The separate feeding mechanism replaces the traditional feeding method, resulting in a simpler and easier-to-operate structure that is more rational and efficient. It also adds safety protection mechanisms to improve the safety of feeding.
[0004] The aforementioned method, which uses a lead screw motor to drive the feeding process instead of manual feeding, avoids the dangers of manual operation. However, some drawbacks remain. For clamping fixtures used with workpieces of different shapes and sizes, manual bolt fixation of the workpiece surface is still required during clamping, resulting in poor adaptability to workpieces of different sizes and reduced feeding speed and efficiency. Therefore, we propose a novel hydraulic press-assisted feeding mechanism to solve these problems. Utility Model Content

To achieve the above objectives, it solves the problem that existing methods still rely on manual bolt fixing when clamping workpieces of different shapes and sizes, resulting in poor adaptability to workpieces of different sizes and reduced feeding speed and efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic press auxiliary feeding mechanism, including a mounting frame, a top plate fixedly connected to the top of the mounting frame by bolts, a hydraulic press embedded in the top plate, a positioning mechanism provided directly below the hydraulic press, clamping mechanisms provided at both ends of the positioning mechanism, and a bottom plate fixedly connected to both sides of the bottom of the mounting frame by bolts;
[0007] The clamping mechanism includes a forward and reverse motor, a first pulley, a second pulley, a belt, a support plate, a first threaded rod, a second threaded rod, engagement holes, and clamping blocks. The output end of the forward and reverse motor is rotatably connected to a rotating shaft via an electric spindle, and the output end of the rotating shaft is provided with a first pulley. A second pulley is provided directly above the first pulley. The first pulley and the second pulley are connected by a belt. Support plates are provided on both sides of the second pulley. One side of the support plate is rotatably connected to one side wall of the second pulley via a first threaded rod, and the other side of the support plate is rotatably connected to the other side wall of the second pulley via a second threaded rod. Clamping blocks are slidably fitted onto the outer walls of the first threaded rod and the second threaded rod, and engagement holes are provided on the bottom surfaces of the two clamping blocks.
[0008] Furthermore, the positioning mechanism includes a shaft, pin holes, a fixing sleeve, a mounting plate, and a mold table. The two side walls of the mounting frame are provided with evenly distributed pin holes. A shaft is inserted into the two pin holes facing each other. The two ends of the shaft are fixedly mounted on the outer wall of the mounting frame by the fixing sleeve. The two ends of the shaft are connected to the mounting plate through the shaft, and the inner wall of the mounting plate abuts against the outer wall of the mounting frame. A mold table is fixedly connected to the top of the two mounting plates.
[0009] Furthermore, the two side surfaces of the mold platform are in contact with the clamping block, and the two side walls of the mold platform are fixedly connected to the support plate.
[0010] Furthermore, the first threaded rod and the second threaded rod have opposite external threads on their outer walls, and the two meshing holes mesh and rotate with the first threaded rod and the second threaded rod.

[0012] Furthermore, the hydraulic press is a single-column hydraulic press.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention utilizes a bottom stirring rod, a forward and reverse motor, a first pulley, a second pulley, a belt, a support plate, a first threaded rod, a second threaded rod, a meshing hole, and a clamping block. The forward and reverse motor drives the first pulley, which in turn drives the second pulley via the belt, achieving mechanical transmission. Simultaneously, the rotation of the second pulley causes the first and second threaded rods in the middle of their side walls to rotate relative to each other. Furthermore, the outer walls of the first and second threaded rods have opposite thread structures, enabling relative sliding clamping of the outer clamping block. This automated clamping replaces manual bolt fixing and can be adaptively adjusted according to the size of the workpiece, significantly improving work efficiency. Attached Figure Description
