Description

Technical Field

[0001] This utility model relates to the field of clutch face plate production, and in particular to a hot pressing molding machine for clutch face plate production. Background Technology

[0002] The clutch face plate is one of the main components of a clutch. It is a composite material whose primary function is friction, while also requiring structural performance. During the processing of the clutch face plate, it needs to be hot-pressed using a hot pressing device. This hot-pressing process is a crucial step in the clutch face plate manufacturing process, directly affecting its appearance and performance.

[0003] Existing technology (patent document with publication number "CN222904934U") discloses a clutch face hot pressing device, including: a machine body and a limiting rod, a bracket fixedly connected to the top of the machine body, and a top plate fixedly connected to the top of the bracket. This clutch face hot pressing device uses connecting rods on both sides of the hot pressing plate and push blocks on the top of the connecting plate to eject the processed clutch face from the machine body, facilitating material removal by workers.

[0004] Based on the above search and combined with existing technology, it was found that the existing hot pressing forming machine for clutch face plate production uses the cooperation of limit rods and protrusions to limit the heating plate, which can prevent the hot plate from falling suddenly and causing danger. However, this setting requires that the moving blocks on both sides be moved to release the limit when the heating plate needs to be driven down. This means that the limit must be released before each hot pressing operation can be carried out. The moving blocks need to be pushed by external force (electric drive or manual push), and additional drive components are required. At the same time, pushing the moving plate also requires linkage with the hydraulic rod, that is, the limit must be released before the hydraulic rod can be started. A corresponding control system is also required. This will undoubtedly greatly increase the equipment cost. At the same time, the increase in components (especially electrical components) will also lead to an increased equipment failure rate, which is not conducive to the stable operation of the equipment. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The core of this utility model lies in improving the existing anti-detachment protection structure to solve the problems of complex structure, high equipment cost, and increased failure rate in the prior art. At the same time, the detachable linkage block (41) and the abutment end (51) facilitate later maintenance and make it more convenient to use.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A hot press forming machine for producing clutch face plates includes a base, a bottom mold structure fixed on the base, a bracket fixed on the bottom mold structure, a top plate fixed on the top of the bracket, a hot press top mold structure slidably connected to the bracket, and a hydraulic cylinder fixed on the top plate. The piston rod of the hydraulic cylinder extends downward and its lower end is fixed to the top of the hot press top mold structure. An ejection mechanism is installed on both the bottom mold structure and the hot press top mold structure. A limit ear plate is fixed to the side wall of the hot press top mold structure.

[0010] A limiting plate is slidably connected to the bottom of the top plate. The limiting plate slides horizontally along the length of the hot press mold structure. The limiting plate is elastically connected to the top plate through an elastic element.

[0011] The lower end of the limiting plate is integrally formed with a limiting base plate. The limiting base plate extends towards the side of the hot press mold structure. The limiting base plate is adapted to the limiting ear plate on the side wall of the hot press mold structure. A linkage block is also fixed on the side of the limiting plate near the ejection mechanism. The linkage block is a wedge block with inclined surfaces on both the top and bottom that protrudes towards the side of the hot press mold structure.

[0012] A linkage rod is also fixed on the piston rod of the hydraulic cylinder. The linkage rod is located at the upper end of the hot press mold structure. A wedge is formed at the end of the linkage rod. When the wedge moves up and down, it abuts against the linkage block and drives the limiting plate to slide away from the outside of the hot press mold structure.

[0013] By sliding the limiting plate onto the bottom of the top plate and using an elastic element to elastically connect the limiting plate to the bottom of the top plate, and fixing a linkage rod on the piston rod of the hydraulic cylinder, a good safety protection effect is achieved. Compared with the complex structure in the prior art, the design structure of this application is simpler, the equipment cost is lower, and the limiting and releasing effects are achieved through mechanical linkage, making it safer, more reliable, less prone to damage, and also reducing subsequent maintenance costs.

[0014] Furthermore, a groove is provided at the bottom of the top plate, and a slider is integrally formed on the top of the limiting plate, which is slidably connected to the groove.

[0015] Furthermore, the elastic element includes a side plate and a compression spring. The side plate is fixed to the bottom of the top plate. The side plate is located on the side of the limiting plate away from the hot press mold structure and is parallel to the limiting plate. The two ends of the compression spring are fixed to the ends of the limiting plate and the side plate respectively.

[0016] Furthermore, there is a gap one between the bottom of the linkage rod and the limiting ear plate of the hot pressing mold structure, and the linkage block is located within the gap one. When the limiting ear plate of the hot pressing mold structure is above the limiting base plate, there is a gap two between the top of the limiting base plate and the bottom of the limiting ear plate. The height of gap two is greater than the vertical height of the inclined surface of the linkage block.

[0017] Preferably, the middle part of the linkage rod has a fixed ring that is fixedly sleeved on the piston rod of the hydraulic cylinder, both ends of the linkage rod have protrusions, both ends of the linkage rod are fixed with abutting ends by bolts, the wedge part is formed at the end away from the abutting end of the linkage rod, and the end of the abutting end close to the linkage rod has a clamping plate that engages with the protrusions.

[0018] The abutting end is provided with a clearance groove for the support to move through, and the clearance groove extends vertically through the abutting end.

[0019] Furthermore, a stud is fixed on the side of the linkage block away from the hot press mold structure. The stud moves horizontally through the limiting plate, and a nut is screwed onto the stud. The linkage block is fixed to the limiting plate by the stud and the nut.

[0020] 3. Beneficial Effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] (1) This solution slides the limiting plate on the bottom of the top plate and uses an elastic element to make the limiting plate elastically connected to the bottom of the top plate. The linkage rod is fixedly installed on the piston rod of the hydraulic cylinder, thereby achieving a good safety protection effect. At the same time, compared with the complex structure in the prior art, the design structure of this application is simpler, the equipment cost is lower, and the limiting and releasing effects are achieved through mechanical linkage, which is safer, more reliable, less prone to damage, and also reduces subsequent maintenance costs.

[0023] (2) This solution allows the abutting end to be detachably installed on the linkage rod, and the linkage block to be detachably fixed on the limit plate, so that both the abutting end and the linkage block can be replaced, making it easier to maintain when the abutting end or the linkage block is severely worn, and making it more convenient to use.

[0030] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0031] Example 1: Please refer to Figures 1-4 A hot press forming machine for producing clutch face plates includes a base 1, a bottom mold structure 11 fixed on the base 1, a bracket 12 fixed on the bottom mold structure 11, a top plate 14 fixed on the top of the bracket 12, a hot press top mold structure 13 slidably connected to the bracket 12, and a hydraulic cylinder 2 fixed on the top plate 14. The piston rod of the hydraulic cylinder 2 extends downward and its lower end is fixed to the top of the hot press top mold structure 13. An ejection mechanism 3 is installed on both the bottom mold structure 11 and the hot press top mold structure 13. A limit ear plate is fixed to the side wall of the hot press top mold structure 13. The aforementioned structures are all prior art, including existing structures in the prior art (for example, the ejection mechanism 3 includes a connecting rod, a lever, a rotating block, a tension spring, a push rod, a connecting plate, and a push block; the hot press top mold structure 13 includes a hot press plate, a heating plate, etc.). The connection relationship, arrangement, and working principle are all consistent with the prior art, and will not be elaborated here.

[0032] A limiting plate 4 is slidably connected to the bottom of the top plate 14. The limiting plate 4 slides horizontally along the length direction of the hot press mold structure 13. The limiting plate 4 is elastically connected to the top plate 14 through an elastic element.

[0033] The lower end of the limiting plate 4 is integrally formed with a limiting base plate 42. The limiting base plate 42 extends towards the side close to the hot pressing mold structure 13. The limiting base plate 42 is adapted to the limiting ear plate on the side wall of the hot pressing mold structure 13. The limiting plate 4 is also fixed with a linkage block 41 on the side close to the ejection mechanism 3. The linkage block 41 is a wedge block with inclined surfaces on both the top and bottom protruding towards the side of the hot pressing mold structure 13.

[0034] A linkage rod 5 is also fixed on the piston rod of the hydraulic cylinder 2. The linkage rod 5 is located at the upper end of the hot press mold structure 13. A wedge block 511 is formed at the end of the linkage rod 5. When the wedge block 511 moves up and down, it abuts against the linkage block 41 and drives the limiting plate 4 to slide away from the hot press mold structure 13.

[0035] By sliding the limiting plate 4 on the bottom of the top plate 14 and elastically connecting the limiting plate 4 to the bottom of the top plate 14 through the elastic element, and fixing the linkage rod 5 on the piston rod of the hydraulic cylinder 2, the linkage block 41 can be abutted by the wedge part 511 at the end of the linkage rod 5, and drive the limiting plate 4 to slide along the top plate 14 away from the limiting ear plate, thereby releasing the limiting effect of the limiting bottom plate 42 at the bottom of the limiting plate 4 on the limiting ear plate. Then the wedge part 511 contacts the limiting bottom plate 42 and pushes the limiting bottom plate 42 outward again, so that the linkage rod 5 can also move downward, so that the hot pressing mold structure 13 can move downward smoothly, and complete the hot pressing forming operation of the clutch face plate.

[0036] After the hot pressing molding operation is completed, the piston rod of the hydraulic cylinder 2 drives the linkage rod 5 and the hot pressing top mold structure 13 to rise synchronously, so that the wedge part 511 contacts the limiting base plate 42 and the connecting block 41 in turn, pushing the limiting plate 4 outward twice to ensure the smooth rise of the linkage rod 5 and the hot pressing top mold structure 13. When the height of the limiting ear plate on the side wall of the hot pressing top mold structure 13 is higher than the height above the limiting base plate 42, and the lower inclined side wall of the wedge part 511 is also higher than the upper inclined surface of the connecting block 41, the limiting plate 4 is reset under the elastic action of the elastic element, so that the limiting plate 4 is reset. When the base plate 42 moves to below the limiting ear plate, the limiting base plate 42 can limit the limiting ear plate. If the hot press mold structure 13 suddenly falls when the piston rod of the hydraulic cylinder 2 is not in the same position, it will be limited and stopped by the limiting base plate 42, thus achieving a good safety protection effect. At the same time, compared with the complex structure in the prior art, the design structure of this application is simpler, the equipment cost is lower, and the limiting and releasing effects are achieved through mechanical linkage, which is not easy to be damaged, reduces the overall failure rate, is safer and more reliable, and also reduces subsequent maintenance costs.

[0037] Furthermore, a groove 141 is provided at the bottom of the top plate 14, and a slider 43 is integrally formed on the top of the limiting plate 4, which is slidably connected in the groove 141.

[0038] Furthermore, the elastic element includes a side plate 6 and a compression spring 7. The side plate 6 is fixed to the bottom of the top plate 14. The side plate 6 is located on the side of the limiting plate 4 away from the hot press mold structure 13 and is parallel to the limiting plate 4. The two ends of the compression spring 7 are fixed to the ends of the limiting plate 4 and the side plate 6 respectively, realizing the elastic connection of the limiting plate 4. This makes it easy to use the elastic force of the compression spring 7 to drive the limiting plate 4 to reset, thereby driving the linkage block 41 and the limiting bottom plate 42 to reset.

[0039] To ensure proper coordination between the linkage block 41, linkage rod 5, limiting ear plate, and limiting base plate 42, and to avoid mutual interference, there is a gap 1 between the bottom of the linkage rod 5 and the limiting ear plate of the hot press mold structure 13. The linkage block 41 is located within this gap 1. When the limiting ear plate of the hot press mold structure 13 is above the limiting base plate 42, there is a gap 2 between the top of the limiting base plate 42 and the bottom of the limiting ear plate. The height of gap 2 is greater than the vertical height of the inclined surface of the linkage block 41. This provides sufficient space for the movement of the limiting ear plate when the wedge portion 511 at the end of the linkage rod 5 abuts against the linkage block 41, preventing the limiting ear plate from contacting the limiting base plate 42 in this state and ensuring the smooth movement of the limiting ear plate.

[0040] Example 2: Please refer to Figure 4 A hot press forming machine for producing clutch face plates, which differs from Example 1 in that:

[0041] The linkage rod 5 has a fixed ring 512 integrally formed in the middle and fixedly sleeved on the piston rod of the hydraulic cylinder 2. Both ends of the linkage rod 5 have protrusions 513 integrally formed. Both ends of the linkage rod 5 are fixed with abutting ends 51 by bolts. The wedge part 511 is formed at the end away from the abutting end 51 and the end of the abutting end 51 close to the linkage rod 5 has a clamping plate 514 integrally formed to engage with the protrusions 513.

[0042] The abutting end 51 is provided with a clearance groove 515 for the bracket 12 to move through, and the clearance groove 515 vertically passes through the abutting end 51;

[0043] In addition, a stud 411 is fixed on the side of the linkage block 41 away from the hot press mold structure 13. The stud 411 moves horizontally through the limiting plate 4, and a nut is screwed onto the stud 411. The linkage block 41 is fixed to the limiting plate 4 by the stud 411 and the nut.

[0044] By detachably mounting the abutting end 51 onto the linkage rod 5 and detachably fixing the connecting block 41 onto the limiting plate 4, both the abutting end 51 and the connecting block 41 can be replaced, making it easier to maintain the abutting end 51 or the connecting block 41 when they are severely worn, and making it more convenient to use.

[0045] The above description is merely a preferred embodiment of this utility model; it encompasses all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
