Description

Technical Field

[0001] This utility model relates to the field of hydraulic machinery technology, specifically a hydraulic press that facilitates material feeding. Background Technology

[0002] A hydraulic press is a mechanical device that uses liquid pressure to form and process materials. It is widely used in pressing, stamping, bending, stretching, and other forming processes of materials such as metals, plastics, and rubber. With the increasing level of industrial automation, the market demand for efficient, safe, and easy-to-operate hydraulic presses is growing. Therefore, developing hydraulic presses that facilitate material feeding has become one of the industry's development trends.

[0003] Patent publication number CN208428728U discloses an automatic feeding hydraulic press, including a base. A feeding box is fixedly connected to the top of the base. Inside the feeding box, a fixed plate and a first sliding rod are fixedly connected sequentially from left to right. A second sliding rod is fixedly connected between one side of the fixed plate and one side of the feeding box. A first push plate is sleeved on the outer surface of the second sliding rod. Through the above mechanical structure and actuators such as an electric telescopic rod, the workpiece can be accurately placed on the pressure block for processing. However, since the clamps and pressure block of this hydraulic press are fixed, some materials may undergo lateral expansion deformation under pressure during the pressing process. If this deformation exceeds expectations, the fixed clamps responsible for holding the workpiece may bear additional pressure or torsional torque, causing damage to the clamps. In this case, the maintenance cost of the equipment increases, and its service life is also reduced. Therefore, we propose a hydraulic press with convenient feeding to overcome the above defects. To solve the above problems, a hydraulic press with convenient feeding is proposed. Summary of the Invention

[0004] To overcome the aforementioned problems in the prior art, a hydraulic press that facilitates material feeding is proposed.

[0005] The technical solution of this utility model is as follows: A hydraulic press for easy feeding includes a hydraulic press body and a mounting frame. The mounting frame is installed on both sides of the hydraulic press body and is fixedly connected to the hydraulic press body. A support plate is fixedly provided at the pressing point of the hydraulic press body. It also includes: two rollers, symmetrically and rotatably mounted on both sides of the mounting frame, with the support plate extending outwards and close to the rollers on both sides; a motor, fixedly mounted on the upper part of one of the support columns of the mounting frame, with the output shaft of the motor connected to the corresponding roller shaft; and two conveyor belts, wound around the rollers at both locations. The conveyor belts pass through the pressing point of the hydraulic press body, and the support plate of the hydraulic press body is supported by the conveyor belts. The lower part includes: connecting plates, which are provided in multiple sets and circumferentially fixed to the side wall of the conveyor belt. Each set of connecting plates consists of two plates, which are symmetrically arranged on the outer surfaces of the two conveyor belts; clamping plates, which are slidably mounted on the connecting plates through guide rods. The clamping plates are arc plates, and the two clamping plates in the same set cooperate with each other to clamp hydraulically operated objects; a first spring, which is located between the clamping plates and the connecting plates. The clamping plates and the spring work together to elastically clamp the objects placed on the support plate. The clamped objects are then transported to the hydraulic press body by a motor-driven conveyor belt for hydraulic processing. When the objects expand and deform during the hydraulic process, the clamping plates compress the springs to elastically adapt to the expansion and deformation of the objects, thus avoiding damage to the clamping plates.

[0006] Furthermore, the guide rod end of the clamping plate is fixedly connected to a support plate that is inclined in the discharge direction. The mounting frame is symmetrically fixed with two extrusion rods near the discharge direction of the conveyor belt. The extrusion rods can extrude each set of support plates conveyed to the discharge point, so that when the support plate passes the extrusion rods, it overcomes the elastic force of the first spring and drives the clamping plate to open outward a certain distance, so that the clamping plate automatically releases the hydraulically wound object when it is in the discharge position, thereby realizing automatic discharge of the object.

[0007] Furthermore, a base plate is fixed to the bottom of the discharge side of the mounting frame, and a collection guide plate is provided on the base plate. A buffer is provided between the collection guide plate and the base plate. The collection guide plate, in conjunction with the buffer, can elastically receive the object released from the clamping plate and fall, so that the hydraulically processed object can be safely guided and collected.

[0008] Furthermore, the guide plate of the collecting guide plate is inclined in a stepped shape, and a buffer pad is also provided on the guide surface of the collecting guide plate. The collecting guide plate can slowly guide the hydraulically processed object out, avoiding damage caused by collision when the object is discharged quickly.

[0009] Furthermore, the buffer includes a sleeve, a sliding rod, and a second spring. The sleeve is fixedly connected to the base plate, the sliding rod is slidably mounted on the sleeve, and the sliding rod is fixedly connected to the bottom surface of the collecting guide plate. The second spring is disposed between the sleeve and the sliding rod, and provides elastic cushioning when an object falls onto the collecting guide plate.

[0010] Furthermore, a feeding hopper is fixedly connected to the hydraulic press body near the material feeding side of the conveyor belt. The feeding hopper is located directly above a set of clamping plates in the initial state. The top of the feeding hopper is a circular discharge port, and the bottom of the feeding hopper is a cylindrical guide cylinder. The cylindrical guide cylinder of the feeding hopper is aligned with a set of clamping plates in the initial state of the first spring. The feeding hopper can correctly place the object to be hydraulically fed onto the support plate between the two conveyor belts and clamp it by the clamping plates at both locations. Finally, the conveyor belt feeds the object.

[0011] The beneficial effects are: 1. The clamping plate can automatically adjust according to the degree of expansion and deformation of the object, avoiding damage caused by the deformation of the object. At the same time, during the material discharge process, the collecting guide plate and the buffer work together to reduce the impact force when the object lands and reduce the loss of the object.

[0012] 2. This utility model can automatically feed materials via a motor-driven conveyor belt. The clamping plate, in conjunction with springs, elastically holds the objects, ensuring their stability and accuracy during transportation. When discharging, the squeezing rod automatically triggers the clamping plate to release the objects, achieving automatic discharge and improving production efficiency.

[0013] 3. The design of this utility model can also ensure that the workpiece to be processed can be accurately placed on the support plate and clamped by the clamping plate, thus preventing the risk of displacement or falling before the workpiece enters the hydraulic press.

Detailed Implementation

[0020] Please refer to Figures 1-5 A hydraulic press for easy feeding includes a hydraulic press body 1 and a mounting frame 2. The mounting frame 2 is installed on both sides of the hydraulic press body 1 and is fixedly connected to the hydraulic press body 1. A support plate 101 is fixedly provided at the pressing point of the hydraulic press body 1. It also includes: two rollers 3, which are symmetrically and rotatably installed on both sides of the mounting frame 2. The support plate 101 extends outward and is close to the rollers 3 on both sides; a motor 31, which is fixedly installed on the upper part of one of the support columns of the mounting frame 2, and the output shaft of the motor 31 is connected to the corresponding roller 3 shaft; two conveyor belts 4, which are provided and wound around the rollers 3 at both points. The conveyor belts 4 pass through the pressing point of the hydraulic press body 1, and the support plate 101 of the hydraulic press body 1 is supported on the lower part of the conveyor belts 4; and a connecting plate. 5. Multiple sets of connecting plates 5 are circumferentially and uniformly fixed to the side wall of the conveyor belt 4. Each set of connecting plates 5 consists of two plates, which are symmetrically arranged on the outer surfaces of the two conveyor belts 4. Clamping plates 6 are slidably installed on the connecting plates 5 through guide rods. Clamping plates 6 are arc plates. The two clamping plates 6 in the same set cooperate with each other to clamp the hydraulically operated object. A first spring 7 is set between the clamping plates 6 and the connecting plates 5. The clamping plates 6 cooperate with the spring to elastically clamp the object placed on the support plate 101. Then, the motor 31 drives the conveyor belt 4 to transport the clamped object to the hydraulic press body 1 for hydraulic processing. When the object expands and deforms during the hydraulic process, the clamping plates 6 can elastically adapt to the expansion and deformation of the object after compressing the spring, so as to avoid damaging the clamping plates 6.

[0021] In this embodiment, the end of the guide rod of the clamping plate 6 is fixedly connected to a spreading plate 8 that is inclined in the discharge direction. The mounting frame 2 is symmetrically fixed with two extrusion rods 9 near the discharge direction of the conveyor belt 4. The extrusion rods 9 can extrude each set of spreading plates 8 that are conveyed to the discharge point. When the spreading plate 8 passes the extrusion rods 9, it overcomes the elastic force of the first spring 7 and drives the clamping plate 6 to spread outward a certain distance. This allows the clamping plate 6 to automatically release the hydraulically wound object when it is in the discharge position, thus realizing automatic discharge of the object.

[0022] In this embodiment, a base plate 10 is fixedly connected to the bottom of the discharge side of the mounting frame 2. A collection guide plate 14 is provided on the base plate 10. A buffer is provided between the collection guide plate 14 and the base plate 10. The collection guide plate 14, in conjunction with the buffer, can elastically receive objects released and falling from the clamping plate 6, so that the hydraulically processed objects can be safely guided and collected. The guide plate of the collection guide plate 14 is inclined in a stepped shape. A buffer pad is also provided on the guide surface of the collection guide plate 14. The collection guide plate 14 can slowly guide the hydraulically processed objects out, avoiding damage caused by collision when the objects are discharged quickly. The buffer includes a sleeve 11, a sliding rod 12 and a second spring 13. The sleeve 11 is fixedly connected to the base plate 10. The sliding rod 12 is slidably installed on the sleeve 11. The sliding rod 12 is fixedly connected to the bottom surface of the collection guide plate 14. The second spring 13 is provided between the sleeve 11 and the sliding rod 12. The second spring 13 provides elastic buffering when objects fall onto the collection guide plate 14.

[0023] In this embodiment, a hopper 15 is fixedly connected to the hydraulic press body 1 near the material feeding side of the conveyor belt 4. The hopper 15 is located directly above a set of clamping plates 6 in the initial state. The top of the hopper 15 is a circular discharge port, and the lower part of the hopper 15 is a cylindrical guide tube. The cylindrical guide tube of the hopper 15 is aligned with a set of clamping plates 6 in the initial state of the first spring 7. The object to be hydraulically fed can be correctly placed on the support plate 101 between the two conveyor belts 4 through the hopper 15 and clamped by the clamping plates 6 at both locations. Finally, the conveyor belt 4 feeds the object.

[0024] First, the object to be processed is placed onto the support plate 101 between the conveyor belts 4 via the hopper 15. Guided precisely by the hopper 15, the object falls accurately above a set of clamping plates 6 in their initial state and is held by the symmetrically arranged clamping plates 6 on both sides. When the object contacts the clamping plates 6, the first spring 7 provides elastic force, allowing the clamping plates 6 to tightly hold the object, ensuring its stability during transport and preventing damage due to excessive clamping force. Then, the motor 31 drives the roller 3 to rotate, moving the two conveyor belts 4 wound around it. As the conveyor belts 4 move, the object held by the clamping plates 6 is smoothly sent to the pressing area of ​​the hydraulic press body 1 for hydraulic processing. During this process, if the object expands or deforms due to hydraulic pressure, the clamping plates 6 can adapt to this change after compressing the first spring 7, avoiding excessive external force on the object and protecting it. The object remains undamaged. After hydraulic processing, the object continues to move towards the discharge direction along the conveyor belt 4. When it reaches the discharge position, the symmetrically arranged extrusion rods 9 on the mounting frame 2 will extrude the expansion plate 8 on the clamping plate 6. Since the expansion plate 8 is inclined towards the discharge direction, when it is subjected to the action of the extrusion rods 9, it will overcome the elastic force of the first spring 7, forcing the clamping plate 6 to expand outward a certain distance, thereby automatically releasing the processed object. Finally, the released object will fall onto the collection guide plate 14 on the discharge side of the mounting frame 2. When the collection guide plate receives the object, the spring between the sleeve 11 and the sliding rod 12 provides buffer, thereby elastically receiving the falling object and slowing down its falling speed. Furthermore, the collection guide plate 14 is inclined in a stepped shape and has a buffer pad on its guide surface, further ensuring that the object is guided and collected slowly and safely, preventing unnecessary collision damage caused by rapid discharge.
