A hydraulic press with a protective structure

Abstract

This utility model discloses a hydraulic press with a protective structure, belonging to the technical field of hydraulic presses. It includes a base, with a hydraulic press lifting mechanism fixedly installed at the top of the base. An upper pressure plate is provided at the bottom of the lifting mechanism, and a lower pressure plate is provided at the bottom of the base, with the upper and lower pressure plates corresponding to each other. Mounting strips are provided on both sides of the upper pressure plate. In this hydraulic press with a protective structure, rotating the guard plate closes on both sides of the upper pressure plate, and moving the fixed bracket engages with the corresponding fixed block surface, causing the guard and guard plate to wrap around the upper pressure plate. Controlling the lifting mechanism of the hydraulic press causes the upper pressure plate to move downwards towards the lower pressure plate. The upper pressure plate then moves the guard and guard plate downwards to contact the base, lifting the guard and guard plate upwards, causing the pressing slide rod to slide upwards inside the mounting plate. The compression return spring deforms and rebounds, ensuring that the guard and guard plate are tightly attached to the base and wrap around the surface of the lower pressure plate, thereby protecting the processing area of ​​the hydraulic press.

Description

Technical Field

[0001] This utility model belongs to the field of hydraulic press technology, specifically a hydraulic press with a protective structure. Background Technology

[0002] A hydraulic press is a forming and processing equipment that uses hydraulic oil as the working medium and relies on a hydraulic pump to drive and control pressure. It converts mechanical energy into hydraulic energy through the pump, causing the hydraulic oil to push the cylinder / piston in a closed pipeline to generate huge thrust, completing processes such as pressing, punching, stretching, and extrusion of materials such as metal, plastic, rubber, wood, and powder. In existing hydraulic presses, the working position is generally directly exposed to the environment. When the workpiece is subjected to heavy pressure, scraps of the workpiece can easily fly out of the working position of the hydraulic press, causing injury to the workers. Therefore, improvements are needed. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a hydraulic press with a protective structure, which solves the problem that when existing hydraulic presses are in operation, the working position of the hydraulic press is generally directly exposed to the environment, and when the workpiece is subjected to heavy pressure, the scrap of the workpiece is easily thrown out of the working position of the hydraulic press, causing injury to the workers.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic press with a protective structure, comprising a base, a hydraulic press lifting mechanism fixedly installed at the top of the base, an upper pressure plate at the bottom of the hydraulic press lifting mechanism, and a lower pressure plate at the bottom of the base, with the upper and lower pressure plates corresponding to each other. Mounting strips are provided on both sides of the upper pressure plate, and a mounting plate is fixedly installed on the bottom of the mounting strip on the side away from the upper pressure plate. Three pressing slide rods are slidably connected through the surface of the mounting plate, and protective covers are fixedly connected to both ends of the three pressing slide rods, with the protective covers sliding against the surface of the mounting plate. A return spring is sleeved on the surface of the pressing slide rods at the bottom of the mounting plate. Protective plates are rotatably installed on both sides of the protective covers via pins. A fixing block is fixedly installed on the side of the protective plate away from the protective cover. A fixing bracket is provided between the two protective plates on the same side of the upper pressure plate, and the fixing bracket is sleeved on the surface of the fixing block.

[0005] As a further embodiment of this utility model: the mounting strip is symmetrically provided with positioning slots on the side near the upper pressure plate, and positioning protrusions are symmetrically fixedly installed on both sides of the upper pressure plate, and the positioning protrusions and positioning slots are correspondingly inserted into each other.

[0006] As a further embodiment of this utility model: a fixing bracket is fixedly installed at the center of the top of the mounting strip, and L-shaped slots are symmetrically provided on both sides of the top of the fixing bracket.

[0007] As a further embodiment of this utility model: mounting brackets are fixedly installed on both sides of the top of the upper pressure plate, and the positions of the mounting brackets and the fixed brackets correspond to each other. Mounting slide rods are symmetrically fixedly installed on both sides inside the mounting brackets.

[0008] As a further embodiment of this utility model: a movable slider is slidably connected through the surfaces of two mounting slide rods on the same side of the mounting bracket, and a fixed spring is sleeved on the surface of the mounting slide rod located on the side of the movable slider.

[0009] As a further embodiment of this utility model: a fixed locking post is fixedly installed on one side of the movable slider outside the mounting frame, and the fixed locking post and the L-shaped slot are correspondingly engaged with each other.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This hydraulic press with a protective structure, by setting up a clamping slide rod, a protective cover, a return spring, and a protective plate, after the mounting strip is fixed to both sides of the upper pressure plate, the protective plate is rotated to close on both sides of the upper pressure plate, and the moving fixed bracket is locked onto the surface of the corresponding fixed block, so that the protective cover and protective plate wrap around the upper pressure plate. The lifting mechanism of the hydraulic press is controlled to lift and move the upper pressure plate down to approach the lower pressure plate. The upper pressure plate moves the protective cover and protective plate down to contact the base, and pushes the protective cover and protective plate up, so that the clamping slide rod slides up inside the mounting plate, compressing the return spring to deform and rebound, ensuring that the protective cover and protective plate are tightly attached to the base and wrapped around the surface of the lower pressure plate, thereby shielding and protecting the processing position of the hydraulic press.

[0012] 2. This hydraulic press with a protective structure, by setting a fixed frame, a movable slider, a fixed spring, and a fixed locking pin, lifts the mounting strip and locks it on both sides of the upper pressure plate, so that the positioning slot engages with the surface of the positioning protrusion. At the same time, the fixed locking pin pushes the movable slider to slide and compress the movable slider on the surface of the mounting slide rod until the fixed frame engages with one side of the mounting frame, so that the fixed locking pin aligns and engages with the inside of the L-shaped locking slot. Under the rebound action of the fixed spring, the fixed locking pin is locked in the inside of the L-shaped locking slot, thus facilitating the removal, cleaning, or installation and fixing of the protective cover from both sides of the upper pressure plate.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a hydraulic press with a protective structure, including a base 1, a hydraulic press lifting mechanism 2 fixedly installed at the top of the base 1, an upper pressure plate 3 at the bottom of the hydraulic press lifting mechanism 2, and a lower pressure plate 4 at the bottom of the base 1, with the upper pressure plate 3 and the lower pressure plate 4 corresponding to each other. Mounting strips 5 are provided on both sides of the upper pressure plate 3, and symmetrical positioning slots 13 are provided on the side of the mounting strips 5 closest to the upper pressure plate 3. Positioning protrusions 14 are symmetrically fixedly installed on both sides of the upper pressure plate 3, and the positioning protrusions 14 and positioning slots 13 are correspondingly inserted into each other. By providing positioning protrusions 14, the mounting strips 5 are lifted and secured to both sides of the upper pressure plate 3, so that the positioning slots 13 are secured to the surface of the corresponding positioning protrusions 14, ensuring that the mounting strips 5 are fixed to both sides of the upper pressure plate 3 without displacement or misalignment.

[0020] Mounting plate 6 is fixedly installed on the bottom of mounting strip 5 on the side away from upper pressure plate 3. Three pressing slide rods 7 are slidably connected through the surface of mounting plate 6. Protective covers 8 are fixedly connected to both ends of the three pressing slide rods 7, and the protective covers 8 slide close to the surface of mounting plate 6. A return spring 9 is sleeved on the surface of the pressing slide rods 7 at the bottom of mounting plate 6. Because of the return spring 9, the protective cover 8 is pressed against the surface of base 1 under the squeezing and rebounding action of the return spring 9, ensuring that the upper pressure plate 3 will not be obstructed when it moves down to the lower pressure plate 4 for processing.

[0021] The protective cover 8 has protective plates 10 mounted on both sides by means of pins. A fixing block 11 is fixedly mounted on the side of the protective plate 10 away from the protective cover 8. A fixing bracket 12 is provided between the two protective plates 10 on the same side of the upper pressure plate 3. The fixing bracket 12 is sleeved on the surface of the fixing block 11. With the fixing bracket 12, when the two protective plates 10 are closed by rotation, the two fixing blocks 11 are pressed together. The fixing bracket 12 is moved to cover the surface of the fixing block 11, thereby closing and fixing the two protective plates 10 on both sides of the upper pressure plate 3, and shielding and protecting the processing position where the upper pressure plate 3 and the lower pressure plate 4 are pressed together.

[0022] Mounting brackets 17 are fixedly installed on both sides of the top of the upper pressure plate 3, and the mounting brackets 17 correspond to the positions of the fixed brackets 15. Mounting slide rods 18 are symmetrically fixedly installed on both sides inside the mounting brackets 17. The surfaces of the two mounting slide rods 18 on the same side of the mounting bracket 17 are slidably connected to movable sliders 19. A fixing spring 20 is sleeved on the surface of the mounting slide rod 18 located on the side of the movable slider 19. Because of the fixing spring 20, the movable slider 19 is pushed to slide on the surface of the mounting slide rod 18, compressing the fixing spring 20 to deform it until the movable slider 19 drives the fixing pin 21 to align with the L-shaped slot 16. After the movable slider 19 is released, the fixed spring 20 pushes the movable slider 19 back to its original position, so that the fixing pin 21 is inserted into the L-shaped slot 16, fixing the mounting strip 5 to both sides of the upper pressure plate 3.

[0023] A fixing bracket 15 is fixedly installed at the center of the top of the mounting strip 5. The fixing bracket 15 has symmetrical L-shaped slots 16 on both sides of its top. A fixing pin 21 is fixedly installed on the side of the movable slider 19 outside the mounting bracket 17. The fixing pin 21 and the L-shaped slot 16 are correspondingly engaged. The fixing bracket 15 lifts the mounting strip 5 to be pressed against both sides of the upper pressure plate 3, causing the fixing pin 21 to engage with the corresponding L-shaped slot 16, thus securing the fixing bracket 15 to one side of the mounting bracket 17 and fixing the mounting strip 5 in place.

[0024] The working principle of this utility model is as follows:

[0025] Lift the mounting strip 5 and move it to both sides of the upper pressure plate 3, so that the positioning slot 13 is engaged with the corresponding positioning protrusion 14. At the same time, push and squeeze the two fixing pins 21 closer together, causing the moving slider 19 to slide on the surface of the mounting slide rod 18 and compress the fixing spring 20 until the fixing frame 15 moves up and aligns with the mounting frame 17. After the fixing pins 21 are engaged in the L-shaped slot 16, release the fixing pins 21. Under the rebound action of the fixing spring 20, push the moving slider 19 back to its original position, so that the fixing pins 21 are engaged in the L-shaped slot 16. Thus, the mounting strip 5 is installed and fixed on both sides of the upper pressure plate 3. Rotate the guard plate 10 on the same side of the upper pressure plate 3 to make it close, and move the fixing frame. 12 are fitted onto the surface of the corresponding fixing block 11, so that the guard plate 10 is tightly wrapped around the surface of the upper pressure plate 3, and the processing position between the upper pressure plate 3 and the lower pressure plate 4 is shielded and protected. When the hydraulic press lifting mechanism 2 is controlled to extend and retract to drive the upper pressure plate 3 to approach the lower pressure plate 4 for processing, the guard 8 and the guard plate 10 are first pressed against the base 1, and the guard 8 is pushed up to slide on the surface of the mounting plate 6, so that the return spring 9 is squeezed and deformed at the bottom of the mounting plate 6 until the upper pressure plate 3 and the lower pressure plate 4 are pressed together. After the processing is completed, the upper pressure plate 3 moves up away from the lower pressure plate 4 until the guard 8 and the guard plate 10 are away from the base 1. Under the rebound action of the return spring 9, the guard 8 drives the guard plate 10 to return to the surface of the upper pressure plate 3.
