Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to a heavy hydraulic press with a buffer device. Background Art

[0002] Heavy hydraulic presses have a wide range of applications. They are indispensable in machinery manufacturing, aerospace, automotive industry, building materials and other industries. For example, in the aerospace field, heavy hydraulic presses can be used to manufacture aircraft parts such as wings and fuselages. In the building materials industry, heavy hydraulic presses can be used to produce cement products, bricks, etc.

[0003] When an existing hydraulic press is used to squeeze a brittle object, the brittle material may be directly broken during the extrusion deformation process. After the object is broken, the hydraulic rod and the extrusion head below will move downward rapidly under the action of the force and hit the base below, generating a large impact force. The impact force cannot be effectively buffered, and the large impact force may cause damage to the base or the extrusion head.

[0004] An existing patent (publication number: CN220864828U) discloses a heavy-duty hydraulic press with a buffer device. When a brittle object breaks, the buffer plate moves downward rapidly under the action of the huge force of the upper extrusion plate, and the movable plate also moves downward rapidly. At this time, the high-viscosity silicone oil will block the fast-moving movable plate and absorb the force generated by the extrusion plate, so that the extrusion plate will not quickly hit the hydraulic platform below, thereby achieving buffering and protection for the extrusion plate.

[0005] In response to the above problems, existing patents have provided solutions, but they are not convenient for positioning the material, which may cause the workpiece to move or shift during the processing process, resulting in inaccurate processing dimensions of the workpiece, affecting the product quality of the workpiece and reducing the quality of the workpiece. In addition, since there is no positioning structure, the position of the workpiece needs to be constantly adjusted, which increases the processing time, affects the processing qualification rate of the workpiece, and reduces the practicality of the device.

[0006] To this end, a heavy hydraulic machine with a buffer device is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a heavy-duty hydraulic press with a buffer device, which can solve the problem that the existing heavy-duty hydraulic press with a buffer device is not convenient for positioning materials, which may cause the workpiece to move or offset during the processing, resulting in inaccurate processing dimensions of the workpiece, affecting the product quality of the workpiece, and reducing the quality of the workpiece. In addition, due to the lack of a positioning structure, the position of the workpiece needs to be continuously adjusted, which increases the processing time, affects the processing qualification rate of the workpiece, and reduces the practicality of the device.

[0008] The top of the hydraulic cylinder is connected with the hydraulic cylinder to move upwards, and the bottom of the hydraulic cylinder is connected with the hydraulic cylinder to move upwards, and the hydraulic cylinder is connected with the hydraulic cylinder to move upwards.

[0009] The fixing assembly includes a processing table, and sliders are movably connected to both sides of the top of the processing table. The tops of the two sliders extend to the top of the processing table and are fixedly connected to a splint, and the opposite sides of the two sliders are fixedly connected to a plurality of first springs.

[0010] Preferably, positioning rods are fixedly connected to the four corners of the bottom of the support plate, and a moving block is fixedly connected to the side of the positioning rod away from the support plate. The surface of the moving block is movably connected to a liquid storage cylinder, and the surface of the liquid storage cylinder is sleeved with a second spring.

[0011] Preferably, a moving groove is provided inside the liquid storage cylinder for use with the moving block, and the interior of the moving groove is filled with high-viscosity silicone oil. A moving hole is provided on the top of the liquid storage cylinder for use with the positioning rod, and the moving hole is connected to the moving groove.

[0012] Preferably, a fixing groove for use with the support plate is provided on the top of the fixing block, and a side of the liquid storage cylinder away from the support plate is fixedly connected to the bottom of the inner wall of the fixing groove.

[0013] Preferably, a slide groove for use with the slider is provided on the top of the processing table, and the sides of the two springs away from the slider are fixedly connected to the two sides of the inner wall of the slide groove respectively.

[0014] Preferably, rubber pads are fixedly connected to opposite sides of the two clamping plates, and the surfaces of the rubber pads are provided with anti-slip grooves.

[0015] Preferably, a pressure gauge is fixedly connected to the front side of the discharge pipe close to the hydraulic cylinder, and a leak-proof interlayer is provided inside the inner wall of the hydraulic cylinder.

[0016] Preferably, both sides of the top of the inner wall of the fixed bracket are fixedly connected to the connecting bracket, and the interior of the connecting bracket is rotatably connected to the ventilation fan.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The present application provides a buffer assembly to buffer the excess impact force when the hydraulic press is pressed down, thereby protecting the base and the pressing block, avoiding damage to the base and the pressing block, ensuring the normal use of the hydraulic press, and improving the convenience of use of the device;

[0019] 2. The present application sets up a fixing component, and by moving the clamping plate, drives the slider to move and compresses the first spring, the fixing effect of the fixing component can be released. Under the action of the first spring, the slider returns to its original position under the restriction of the slide groove, driving the clamping plate to move to the opposite side and contact the surface of the workpiece, so that workpieces of a certain specification can be fixed, ensuring that the clamping plate can move with the change of the shape of the workpiece to maintain a certain clamping effect, avoiding the shaking of the workpiece during the processing, and improving the flexibility of the use of the fixing component.

Thus, the hydraulic press can run smoothly, and then under the action of the pressure gauge 19, the situation inside the hydraulic cylinder 5 can be observed, ensuring that the hydraulic press can be used normally. Under the action of the leak-proof interlayer 20, when there is a problem with the hydraulic cylinder 5, the hydraulic oil is prevented from splashing around and polluting the working environment, ensuring the cleanliness of the working environment. Through the coordinated use of the support plate 202 and the fixed groove 16, the support plate 202 moves smoothly under the restriction of the fixed groove 16, and is connected to the moving groove 14 through the moving hole 15, so that the positioning rod 203 drives the moving block 2 04 moves smoothly under the restriction of the moving groove 14, and then under the action of the high-viscosity silicone oil inside the moving groove 14, it can buffer the impact force of the downward pressure, so that the processing table 301 can be buffered, ensuring the normal use of the hydraulic press, and under the action of the second spring 206, it generates a reaction force, which can drive the support plate 202 to return to its original position, thereby achieving buffering and protection of the pressing block 8 and the base 1, and then under the action of the ventilation fan 22, the temperature of the surface of the hydraulic cylinder 5 can be reduced, further ensuring the stable operation of the hydraulic press.
