Description

Technical Field

[0001] This utility model relates to the field of composite friction material processing technology, specifically a composite friction material curing device. Background Technology

[0002] Composite friction materials are widely used in braking, transmission, and other systems of various machines, and their performance directly affects the operational stability and safety of the equipment. To ensure that composite friction materials possess good mechanical and frictional properties, they typically require curing under high temperature and high pressure to ensure that the internal components of the material are fully cross-linked and formed. Therefore, the curing equipment must provide a stable high temperature and high pressure environment to guarantee the curing effect.

[0003] However, the material handling process of some existing composite friction material equipment is cumbersome, and it requires waiting for natural cooling or complicated operations before material can be handled, which greatly reduces production efficiency and makes it difficult to meet the needs of mass production for convenient and efficient material handling.

[0004] To address these issues, a composite friction material curing device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a composite friction material curing device that has the advantages of convenient and safe material handling operation, while improving material handling efficiency, thus solving the problem of low material handling efficiency in some existing composite friction material curing devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite friction material curing device, comprising an outer chamber, a curing chamber installed inside the outer chamber, a cover on the top of the curing chamber, a handle frame installed on the outer chamber, and a limit buckle installed on the handle frame; an adjusting component installed inside the curing chamber, a placement frame installed on the adjusting component, the adjusting component comprising a top plate, an elastic element, and a bottom plate, the top plate for supporting the placement frame, and a limit ring installed on the top plate; an mounting frame installed on the cover, a latch installed on the mounting frame, a three-way valve installed on the mounting frame, and a positioning frame installed at the bottom of the cover; the latch and the limit buckle cooperate to achieve a closed fit between the cover and the outer chamber, and the positioning frame and the limit ring cooperate to achieve compression and positioning of the adjusting component.

[0007] Preferably, the outer chamber is equipped with a water-cooling component and a heating component. The water-cooling component is used to cool the medium injected into the outer chamber, and the heating component is used to heat the medium injected into the outer chamber.

[0008] In the design, the water-cooling and heating components installed on the outer chamber respectively realize the cooling and heating operations of the medium injected into the outer chamber. It has the advantages of adjusting the ambient temperature inside the outer chamber as needed and adapting to the temperature requirements of the composite friction material curing stage, as well as the heating curing and cooling material unloading stages.

[0009] Preferably, the lower surface of the top plate is connected to the bottom plate via an elastic member, which provides a restoring elastic force to the top plate.

[0010] In the design, the lower surface of the top plate of the adjustment component is connected to the bottom plate through a spring member, and the spring member provides a reset spring force for the top plate. It has the advantage of automatically moving the top plate and the upper placement rack upward after the cover is opened, thereby reducing the manual adjustment steps when picking up materials.

[0011] Preferably, the buckle and the limiting buckle can be engaged to lock and fix the cover to the outer compartment.

[0012] In the design, the buckles on the mounting bracket can engage with the limit buckles on the outer compartment handle bracket to lock and fix the cover to the outer compartment. This has the advantages of enhancing the sealing performance of the cover and the outer compartment after they are closed and preventing pressure leakage or temperature loss during the curing process.

[0013] Preferably, the mounting bracket has a through hole in the middle of its top, and the three-way valve passes through the mounting bracket and the cover to control the pressurization and depressurization operations during the curing process.

[0014] In the design, a through hole is opened in the middle of the top of the mounting frame, and a three-way valve runs through the mounting frame and the cover to control the pressurization and depressurization operations during the curing process. It has the advantages of adjusting the pressure in the curing chamber as needed and accurately matching the high-pressure curing process requirements of composite friction materials.

[0015] Preferably, the bottom of the positioning frame can be inserted into the limiting ring for limiting and compressing the adjustment component.

[0016] In the design, the bottom of the positioning frame can be inserted into the limiting ring on the top plate of the adjustment component to achieve the limiting and compression of the adjustment component. It has the advantages of accurately positioning the adjustment component when the cover is closed and preventing the adjustment component from shifting during the curing process and affecting the material forming.

[0017] Preferably, the bottom of the curing chamber does not contact the bottom of the inner wall of the outer chamber, and the outer chamber is filled with a medium for transferring temperature.

[0018] In the design, the bottom of the curing chamber does not contact the bottom of the inner wall of the outer chamber, and the outer chamber is filled with a medium for transferring temperature. This allows the temperature of the outer chamber heated by the heating components to be evenly transferred to the curing chamber through the medium, which has the advantage of ensuring the curing temperature of the composite friction material.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model includes an outer chamber, a curing chamber, and a cover, as well as a handle and limit buckle installed on the outer chamber, an adjustment component and a placement rack installed inside the curing chamber, and an installation rack, a latch, a three-way valve, and a positioning rack installed on the cover. The adjustment assembly includes a top plate, an elastic element, and a bottom plate, with a limit ring on the top plate, achieving the effect of convenient and safe material handling while improving material handling efficiency.

[0020] Before material removal, the pressure can be directly controlled by the three-way valve, without complicated operation; after pressure removal, the cover can be quickly opened by the cooperation of the latch and the limit buckle, avoiding the cumbersome opening and closing steps in traditional material removal; after the cover is opened, the elastic part of the adjustment component can drive the top plate of the support and placement rack to move up, without the need for operators to manually enter the curing chamber to grab the material, which reduces the difficulty of operation and avoids the safety hazards caused by contact with high temperature areas. Meanwhile, the cooperation between the positioning frame and the limiting ring ensures that the position of the adjustment component is stable when the cover is closed, and the top plate moves up smoothly after the cover is opened. The placement frame can be taken out from the curing chamber together with the cured material, further reducing the material handling steps. The synergistic effect of the above structures effectively solves the problem of cumbersome and inefficient material handling process in some existing composite friction material curing equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: a composite friction material curing device, including an outer chamber 1, which is a hollow cavity structure with an open top. A curing chamber 2 is installed inside the outer chamber 1. The curing chamber 2 is also a cavity structure with an open top, and the bottom of the curing chamber 2 does not contact the bottom of the inner wall of the outer chamber 1. A medium for transferring temperature is injected into the outer chamber 1. The medium is heat-conducting oil, and the injection amount is preferably such that the temperature can be transferred evenly. The top of the curing chamber 2 is provided with a cover 3, which can completely cover the top opening of the curing chamber 2. Two handles 13 are symmetrically installed on the outer side wall of the outer chamber 1. Each handle 13 is equipped with a limit buckle 131 at both ends away from the outer chamber 1. The limit buckle 131 is a metal component with a buckle groove, which is used to connect and position with the cover 3. The outer wall of the outer chamber 1 is also equipped with a water-cooling component 11 and a heating component 12. The water-cooling component 11 is a coil-type water-cooling structure, with the coil extending into the outer chamber 1 and located below the curing chamber 2. It includes a temperature gauge, a circulation pump, a cooling chamber, heat dissipation fins located outside the cooling chamber, and a cooling fan installed at the location of the heat dissipation fins. The water-cooling component 11 is used to rapidly cool the medium injected into the outer chamber 1. The heating component 12 is an electric heating tube structure, with the electric heating tube extending into the outer chamber 1 and located below the liquid surface of the medium. It is used to heat the medium injected into the outer chamber 1. The heating temperature can be adjusted according to the curing requirements of the composite friction material.

[0025] A groove is cut into the upper part of the outer wall of the curing chamber 2, which is in contact with the outer chamber 1, and a high-temperature resistant sealing ring is embedded therein; an adjustment component 21 is installed inside the curing chamber 2, which is used to realize the rapid removal of the composite friction material after curing; a placement rack 22 is provided inside the curing chamber 2 and above the adjustment component 21, which is a grid-shaped metal rack used to support the composite friction material blank to be cured. Adjustment component 21 includes top plate 211, elastic element 212 and bottom plate 213. Top plate 211 is a circular metal plate with a diameter that matches the inner diameter of curing chamber 2. The upper surface of top plate 211 has a ring array integrally formed limiting ring 2111. The limiting ring 2111 is a ring metal protrusion. The limiting ring 2111 works with cover 3 to limit the adjustment component 21. Multiple elastic elements 212 are evenly distributed on the lower surface of the top plate 211. The elastic elements 212 are cylindrical compression springs. The end of each elastic element 212 away from the top plate 211 is fixedly connected to the upper surface of the bottom plate 213. The bottom plate 213 is also a circular metal plate with the same diameter as the top plate 211. The edge of the bottom plate 213 slides against the inner wall of the curing chamber 2. The elastic elements 212 are used to provide a reset force for the top plate 211. The elastic force should be large enough to support the total weight of the top plate 211, the placement rack 22, and the blank. The bottom plate 213 is used to install the elastic elements 212 in conjunction with the top plate 211 and to adjust the stable placement of the component 21 in the curing chamber 2. The bottom plate 213 can be placed directly on the annular protrusion at the lower part of the inner wall of the curing chamber 2 to avoid excessive downward movement.

[0026] A high-temperature resistant sealing ring is provided at the connection between the bottom of the cover 3 and the curing chamber 2. An installation frame 31 is fixedly installed in the center of the upper surface of the cover 3. The installation frame 31 is an "X" shaped metal frame. A buckle 311 is installed on the installation frame 31. The buckle 311 is a component with a movable buckle tongue. The buckle 311 corresponds one-to-one with the limiting buckle 131 on the outer chamber 1. The buckle tongue of the buckle 311 can be fastened into the buckle groove of the limiting buckle 131 to achieve the locking and fixing of the cover 3 and the outer chamber 1. A circular through hole is provided in the middle of the top of the mounting frame 31. A three-way valve 32 is sealed and installed in the through hole. One end of the three-way valve 32 passes through the mounting frame 31 and the cover 3 and extends into the curing chamber 2. The other two ends are connected to an external pressurizing device and a pressure relief pipe, respectively. The external pressurizing device is an air compressor. The three-way valve 32 is used to control the pressurization operation before curing and the pressure relief operation after curing. The pressurization pressure can be adjusted according to the curing requirements of the composite friction material. The bottom of the cover 3 is vertically fixed with positioning frames 33 in a circular array. The positioning frames 33 are cylindrical metal rods whose length is adapted to the distance from the cover 3 to the limiting ring 2111 after the cover is closed. The positioning frames 33 are used to cooperate with the limiting ring 2111 and are inserted into the limiting ring 2111 when the cover 3 is closed, thereby limiting and supporting the adjustment component 21 and preventing the top plate 211 from shifting during the curing process.

[0027] When using this utility model, heat transfer oil medium is injected into the outer chamber 1 until the preset injection amount is reached, and the composite friction material blank to be cured is laid flat on the placement rack 22 of the curing chamber 2. Then, the curing chamber 2 with the adjustment component 21 and the placement rack 22 assembled is placed into the outer chamber 1 to ensure that the distance between the outer wall of the curing chamber 2 and the inner wall of the outer chamber 1 is uniform. Then, cover the top of the curing chamber 2 with the cover 3, align the positioning frame 33 at the bottom of the cover 3 with the limiting ring 2111 on the top plate 211 and insert it. Then, fasten the buckle 311 on the mounting frame 31 with the limiting buckle 131 on the handle frame 13 of the outer chamber 1. The cover 3 is locked by the buckle 311. At this time, the cover 3 will apply downward pressure to the top plate 211, compress the elastic element 212, so that the top plate 211 and the placement frame 22 placed on the top plate 211 move down to the preset position inside the curing chamber 2.

[0028] Then, the heating component 12 on the outer chamber 1 is activated to heat the medium. The temperature of the medium is monitored in real time by a temperature sensor preset on the heating component 12. After the temperature rises to the preset curing temperature and stabilizes, the pressurization passage of the three-way valve 32 is opened, and the external air compressor pressurizes the curing chamber 2. The pressure is controlled by a pressure gauge preset on the external air compressor until the pressure reaches the preset curing pressure. This temperature and pressure state is maintained until the preset curing time, so that the composite friction material is fully cured in a high temperature and high pressure environment.

[0029] After curing is complete, first turn off the heating component 12. If it is necessary to speed up the cooling process, the water cooling component 11 can be activated to cool the medium. When the medium temperature drops to the preset material dispensing temperature, turn off the water cooling component 11. Then, open the pressure relief passage of the three-way valve 32 to depressurize the curing chamber 2. After the pressure gauge shows zero pressure, the pressure gauge is installed on the pressure relief pipe. Loosen the latch 311 and the limit latch 131 and move the cover 3 upward. At this time, the elastic element 212 in the adjusting component 21 loses the pressure restriction of the cover 3, automatically resets and pushes the top plate 211 upward, causing the placement rack 22 on the top plate 211 and the cured composite friction material to move upward together until the elastic element 212 returns to its initial state. At this time, the top of the placement rack 22 will be higher than the top opening of the curing chamber 2. The operator can directly hold the edge of the placement rack 22 and quickly take out the cured composite friction material together with the placement rack 22 from the curing chamber 2 to complete the material removal operation.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
