[0002] Phenolic resin is one of the commonly used materials for producing clutch discs and brake pads in the prior art. Phenolic resin can provide excellent adhesiveness, firmly bonding abrasive or friction materials to the surface of the clutch disc. It maintains stability at high temperatures and will not fail, ensuring consistent performance. It has hardness and wear resistance, which helps to improve the durability and lifespan of the clutch disc.
[0003] In the prior art, high-pressure extrusion molding is often used in the production of phenolic resin wear-resistant clutch facing pieces to form the clutch facing pieces. However, in such extrusion molding equipment in the prior art, after the extrusion is completed, the forming components inside the forming groove need to be taken out, then the next batch of workpieces are put in, and then the extrusion work is carried out again, and so on. During the time of taking out this component and putting in the component that needs to be extrusion molded, the production work cannot continue, so it is easy to delay the production efficiency. Therefore, an extrusion molding device for a modified thermosetting phenolic resin wear-resistant clutch facing piece is needed to improve this problem. Summary of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: a modified thermosetting phenolic resin wear-resistant clutch facing extrusion molding device, including a workbench 1. On one side of the upper end of the workbench 1, an extrusion mechanism is provided. The extrusion mechanism includes a fixed rod 2, a top plate 3, a movable plate 4, and a hydraulic cylinder 5. On both sides of the upper end of the workbench 1, fixed rods 2 are fixedly arranged. On the upper end of the fixed rod 2, a top plate 3 is fixedly arranged. In the middle of the surface of the fixed rod 2, a movable plate 4 is movably sleeved. In the middle of the inner side of the top plate 3, a hydraulic cylinder 5 is fixedly arranged. A fixed connection is provided between the movable end of the hydraulic cylinder 5 and the movable plate 4. Inside the workbench 1, a feeding mechanism for multi-station feeding is provided.
[0022] The feeding mechanism includes a first chute 6, a second chute 7, a first slide plate 8, a second slide plate 9, a connecting column 10, a first station 11, and a second station 12. A first chute 6 is opened on the outer surface of the workbench 1. A second chute 7 is opened on the outer surface of the workbench 1 below the first chute 6. Inside the first chute 6, a first slide plate 8 is movably engaged. Inside the second chute 7, a second slide plate 9 is movably engaged. Inside the second slide plate 9, a connecting column 10 is movably inserted. On the upper end of the first slide plate 8, a first station 11 is fixedly arranged. On the upper end of the connecting column 10, a second station 12 is fixedly arranged; through the feeding mechanism, double-station feeding can be facilitated. One station is used for processing, and the other station can be used for discharging and feeding. In this way, the feeding time can be saved, and thus the processing efficiency can be improved;
[0023] At the four corners of the upper surface of the first station 11 and the second station 12, telescopic rods 13 are fixedly arranged. The movable end of the telescopic rod 13 is fixedly provided with an extrusion plate 14. By moving the movable plate 4 downward to squeeze the extrusion plate 14, the extrusion plate 14 is moved downward, so that the parts can be squeezed in cooperation with the first station 11 or the second station 12; to produce clutch plates;
[0024] A spring 15 is sleeved on the outer surface of the telescopic rod 13. Through the spring 15, it is convenient to automatically push the telescopic rod 13 and the extrusion plate 14 to move upward and reset;
[0025] A guide rail 16 is fixedly arranged at the lower end inside the workbench 1. The lower end of the connecting column 10 is movably provided with a roller 17 through a rotating shaft. The outer surface of the roller 17 is mutually attached to the outer surface of the guide rail 16. When the second slide plate 9 and the second working station 12 move left and right, the connecting column 10 and the second working station 12 can be automatically controlled to move up and down through the guide rail 16, so that the second working station 12 and the first working station 11 can be staggered, facilitating the staggered movement of the second working station 12 and the first working station 11. The roller 17 can avoid unnecessary frictional losses;
[0026] One side of the surface of the workbench 1 is movably provided with a first pulley 18 through a rotating shaft. A connecting belt 19 is sleeved between the first pulleys 18. A motor 20 is fixedly arranged on the surface of the workbench 1 on one side of the first pulley 18. The output shaft end of the motor 20 is fixedly provided with a second pulley 21 in the middle of the surface of the first pulley 18 through a coupling. A transmission belt 22 is sleeved between the second pulleys 21. The first slide plate 8 is fixedly connected to the outer surface of the upper end of the connecting belt 19, and the second slide plate 9 is fixedly connected to the outer surface of the lower end of the connecting belt 19. The motor 20, the second pulley 21, and the transmission belt 22 drive the first pulley 18 to rotate, so as to drive the connecting belt 19 to move. When the connecting belt 19 moves, it can drive the first slide plate 8 and the second slide plate 9 to move relatively inside the first chute 6 and the second chute 7, so as to drive the first working station 11 and the second working station 12 to move relatively.
[0027] Working principle: When using this device, the device is provided with two working stations. Initially, the first working station 11 is located at the lower end of the movable plate 4. At this time, when the hydraulic cylinder 5 extends, it can push the movable plate 4 downward, and then the extrusion plate 14 can be squeezed through the movable plate 4. In this way, the extrusion plate 14 can be used to extrude and form the clutch parts at the upper end of the first working station 11;
[0028] At this time, the staff can use the time when the upper end of the first working station 11 extrudes and processes parts to place the clutch parts to be processed into the second working station 12; after the parts at the first working station 11 are processed; the motor 20, the second pulley 21, and the transmission belt 22 drive the first pulley 18 to rotate, so as to drive the connecting belt 19 to move. When the connecting belt 19 moves, it can drive the first sliding plate 8 and the second sliding plate 9 to move relatively inside the first sliding groove 6 and the second sliding groove 7, so as to drive the first working station 11 and the second working station 12 to move relatively; that is to say, it can drive the first working station 11 to move away from the extrusion mechanism, and then drive the second working station 12 to move closer to the extrusion mechanism, so that the positions of the first working station 11 and the second working station 12 are exchanged. With such two working stations, the clutch facings can be extruded and formed alternately using the two working stations. When one clutch facing is being extruded and formed, the staff can use this processing time to unload and load materials for the other working station, which can save the loading time and thus improve the processing efficiency;
[0029] Moreover, when the second sliding plate 9 and the second working station 12 of this device move, the connecting column 10 and the second working station 12 can be automatically controlled to move up and down through the guide rail 16, so that the second working station 12 and the first working station 11 can be staggered to facilitate the staggered movement of the second working station 12 and the first working station 11, and unnecessary frictional losses can be avoided through the roller 17.
