Description

Technical Field

[0001] This invention relates to the field of gear processing technology, and more particularly to a thermosetting equipment and method for gear processing in gear pumps. Background Technology

[0002] Existing thermosetting equipment for gear pump gear processing typically consists of a fixed frame, an integrated mold, a heating module, a pressurizing mechanism, and a cooling system. The working process generally involves: injecting thermosetting material into a mold cavity of fixed dimensions; heating the entire mold via the heating module to induce a cross-linking reaction and solidify the material; simultaneously, the pressurizing mechanism maintains cavity pressure to prevent bubbling; finally, the formed gear is cooled using water or air cooling; and once the temperature drops to a set value, the mold is manually or mechanically separated to complete demolding. The molds in this type of equipment are mostly of an integral structure with fixed cavity dimensions, relying primarily on a single heating curve and constant pressure to achieve thermosetting processing.

[0003] However, during the existing mold cavity heating and pressurization process, the mold is prone to gaps due to uneven stress or differences in thermal expansion coefficients, which causes thermosetting materials to overflow and form flash, affecting gear accuracy. Secondly, the use of direct blowing of room temperature medium or rapid cooling can easily cause excessive temperature difference between the inside and outside of the gear, generating internal stress, causing tooth surface cracking or deformation, and affecting product qualification rate. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantage of difficulty in demolding the gear processing thermoforming. To this end, we propose a gear processing thermosetting equipment and method for gear pumps.

[0005] To achieve the above objectives, this application adopts the following technical solution: a thermosetting equipment for gear processing in a gear pump, comprising a main frame, a guide column connected to the top of the main frame, a mounting panel mounted on the top of the guide column, a drive motor connected to the top of the mounting panel, a drive screw connected to the output end of the drive motor, a transmission gear connected to the top of the drive screw, a transmission belt sleeved on the outer surface of the transmission gear, and an upper cover provided on the outer surface of the drive screw; a thermosetting processing assembly is placed on the upper surface of the main frame, the thermosetting processing assembly including a combination plate. The combined plate has guide posts inserted through it. The upper surface of the combined plate has through holes, mold cavities, and slots. The drive screw is embedded in the through holes. The edge of the mold cavity has a sealing groove. The bottom end of the combined plate is connected to a fitting block. Multiple sets of combined plates are provided. The fitting block on the bottom surface of the upper set of combined plates is embedded in the sealing groove on the surface of the lower set of combined plates. The side of the combined plate is connected to a traction rope. The side of the upper cover is connected to a lifting belt. The other end of the lifting belt is connected to the combined plate. The top of the combined plate is provided with a pressure plate. The combined plate is located between the pressure plate and the main frame of the equipment.

[0006] Preferably, there are four drive screws, and each of the four drive screws is connected to a transmission gear at its top end. The outer surface of the transmission gear is covered with a transmission belt. The output end of the drive motor is connected to one of the drive screws, and the other three drive screws are driven to rotate synchronously through the transmission belt and the transmission gear.

[0007] Preferably, the outer surface of the drive screw is threadedly connected to the upper cover, and the rotation of the drive screw drives the upper cover to move vertically.

[0008] Preferably, a stabilizing component is embedded inside the upper cover. The stabilizing component includes an insertion frame that is embedded inside the upper cover. A drive rod is connected to the side of the upper cover, and a motor is provided at the bottom end of the drive rod, which drives the drive rod to rotate.

[0009] Preferably, a transmission frame is sleeved on the outer surface of the drive rod, the transmission frame and the drive rod are vertically threaded together, one end of the transmission frame is connected to the insertion frame, and the transmission frame drives the insertion frame to move vertically.

[0010] Preferably, the combination plates are made of metal, and each set of the combination plates is stacked together, with the drive screw penetrating the interior of the combination plate and extending to the upper surface of the main frame of the equipment.

[0011] Preferably, a traction rope connects the combined panels to each other, and the traction rope connects multiple sets of combined panels together.

[0012] A thermosetting method for gear machining in a gear pump includes the following steps:

[0013] S1: Select the corresponding number of combination plates according to the specifications of the gears to be processed, stack them on the main frame of the equipment through the guide column, so that the interlocking block on the bottom surface of the upper combination plate is embedded in the sealing groove of the lower group, connect the adjacent combination plates with the traction rope, and then cover the top combination plate.

[0014] S2: Start the drive motor to drive the drive screw to rotate. Through the transmission gears and belts, multiple sets of drive screws rotate, driving the upper cover to descend along the guide column. Press the pressure plate to make the combined plate fit tightly to form a closed thermosetting chamber.

[0015] S3: Start the motor of the stabilizing component, drive the rod to rotate, and descend through the transmission frame to insert the frame into the slot of the combination plate to prevent thermal expansion. Inject thermosetting material into the chamber and maintain pressure to complete the thermosetting process.

[0016] S4: After thermosetting, the motor drives in reverse, the upper cover rises, and is separated into fins by the combination plate of the lifting belt and traction rope. The air is laterally guided to cool, and after absorbing heat through the gap of the combination plate, it is blown toward the gear and cooled to a stable state.

[0017] S5: Continue lifting the cover plate and detaching it from the main frame of the equipment. The gears slide off due to gravity and demold. The combined plate is then reset for the next processing.

[0018] Preferably, during the process of injecting thermosetting material into the cavity and maintaining a preset pressure holding time to complete the thermosetting molding, the thermosetting temperature is controlled in segments, the preset pressure holding time is maintained, and during the pressure holding process, the inserted frame continuously applies a lateral constraint force to the composite plate.

[0019] Preferably, the lateral cold air is introduced and blown toward the formed gear after absorbing residual heat through the gap between the combined plates.

[0020] The technical effects and advantages of this invention are as follows:

[0021] In this invention, by increasing or decreasing the number of combination plates or replacing combination plates with different mold cavity specifications, the gear pump gear processing requirements with different numbers of teeth and tooth widths can be quickly adapted, completely solving the limitation of traditional equipment with one mold per specification, greatly improving the equipment's versatility, shortening the mold change cycle, and reducing mold costs. At the same time, relying on the precise fitting of the interlocking blocks and sealing grooves between the combination plates to eliminate the fitting gaps, and with the lateral rigid constraint of the stabilizing components on the thermal expansion of the combination plates, the cavity size deviation is effectively avoided, and the overflow of thermosetting materials and the generation of flash are prevented. Furthermore, the fin-like structure formed by the separation of the combination plates enables the gradient cooling of cold air after the residual heat is absorbed, avoiding the internal stress and tooth surface cracking caused by sudden cooling. Combined with the synchronous transmission of the drive screw and the smooth demolding achieved by the traction rope and lifting belt, the equipment's ability to adapt to multiple specifications is ensured, the gear forming accuracy is significantly improved, surface defects are reduced, and the product qualification rate and production efficiency are greatly improved.

[0034] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0035] Reference Figures 1-10As shown, the present invention provides a technical solution: a thermosetting equipment for gear processing of a gear pump, comprising a main frame 11, a guide column 12 connected to the top of the main frame 11, a mounting panel 13 mounted on the top of the guide column 12, a drive motor 15 connected to the top of the mounting panel 13, a drive screw 18 connected to the output end of the drive motor 15, a transmission gear 16 connected to the top of the drive screw 18, a transmission belt 17 sleeved on the outer surface of the transmission gear 16, and an upper cover 14 provided on the outer surface of the drive screw 18, the outer surface of the drive screw 18 being threadedly connected to the upper cover 14, the drive screw 18 rotating to drive the upper cover 14 to move vertically; a thermosetting processing assembly 2 is placed on the upper surface of the main frame 11, the thermosetting processing assembly 2 comprising a combination plate 21, the combination plate 21 being made of metal, each set of combination plates 21 being stacked together, and the drive screw 18 penetrating through the inner part of the combination plate 21. The assembly extends to the upper surface of the main frame 11. A guide post 12 is inserted into the assembly plate 21. The upper surface of the assembly plate 21 has a through hole 24, a mold cavity 25, and a slot 27. The drive screw 18 is embedded in the through hole 24. A sealing groove 26 is provided on the edge of the mold cavity 25. A fitting block 29 is connected to the bottom end of the assembly plate 21. Multiple sets of assembly plates 21 are provided. The fitting block 29 on the bottom surface of the previous set of assembly plates 21 is embedded into the sealing groove 26 on the surface of the next set of assembly plates 21. A traction rope 23 is connected to the side of the assembly plate 21. A traction rope 23 is connected between the assembly plates 21. The traction rope 23 connects multiple sets of assembly plates 21 together. A lifting belt 22 is connected to the side of the upper cover 14. The other end of the lifting belt 22 is connected to the assembly plate 21. A pressure plate 28 is provided at the top of the assembly plate 21. The assembly plate 21 is located between the pressure plate 28 and the main frame 11.

[0036] By cooperating with the four sets of guide columns 12 and the drive screw 18, and with the synchronous transmission of the transmission gear 16 and the transmission belt 17, the upper cover 14 is ensured to remain horizontal during vertical movement, avoiding tilting of the combined plate 21 due to uneven force, thus ensuring the fitting accuracy of multiple sets of combined plates 21 after stacking. Secondly, the combined plate 21, through the interlocking of the interlocking block 29 and the sealing groove 26, can form an annular sealing structure during thermosetting, effectively preventing the thermosetting material in the mold cavity 25 from overflowing from the gap of the combined plate 21 due to pressure, reducing material waste and avoiding flash after gear forming. Adjusting the overall depth of the mold cavity 25 by increasing or decreasing the number of combined plates 21, and replacing them with different sizes of mold cavity 25, can adapt to the gear processing requirements of gear pumps with different numbers of teeth and tooth widths, improving the versatility of the equipment.

[0037] A stabilizing component 3 is embedded inside the upper cover 14. The stabilizing component 3 includes an insertion frame 31, which is embedded inside the upper cover 14. A drive rod 33 is connected to the side of the upper cover 14. A motor is provided at the bottom of the drive rod 33. The motor drives the drive rod 33 to rotate. A transmission frame 32 is sleeved on the outer surface of the drive rod 33. The transmission frame 32 and the drive rod 33 are vertically threaded together. One end of the transmission frame 32 is connected to the insertion frame 31. The transmission frame 32 drives the insertion frame 31 to move vertically.

[0038] By fitting the insertion frame 31 into the slot 27 of the combination plate 21, a lateral constraint can be formed on the combination plate 21 during the thermosetting process, effectively limiting the thermal expansion deformation of the combination plate 21 caused by temperature rise. Especially for the metal combination plate 21, which is prone to slight outward expansion at high temperatures, the insertion frame 31 can maintain the stability of the outer dimensions of the combination plate 21 through rigid support, and prevent the tooth profile of the mold cavity 25 from shifting due to the deformation of the combination plate 21, ensuring that the tooth pitch and tooth thickness accuracy of the gear after forming meet the requirements of gear pump transmission.

[0039] A thermosetting method for gear machining in a gear pump includes the following steps:

[0040] S1: Select the corresponding number of combination plates 21 according to the specifications of the gear to be processed, stack them on the main frame of the equipment through the guide column 12, so that the interlocking block 29 on the bottom surface of the upper combination plate 21 is embedded in the lower sealing groove 26, connect the adjacent combination plates 21 with the traction rope 23, and then cover the top combination plate 28 on the top combination plate 21.

[0041] S2: Start the drive motor 15, drive the drive screw 18 to rotate, and use the transmission gear 16 and transmission belt 17 to make multiple sets of drive screws 18 rotate, drive the upper cover 14 to descend along the guide column 12, press the pressure plate 28 to make the combined plate 21 tightly fit together to form a closed thermosetting chamber.

[0042] S3: Start the motor of the stabilizing component 3, drive the rod 33 to rotate, and descend through the transmission frame 32 with the insertion frame 31 to embed into the slot 27 of the combination plate 21 to prevent thermal expansion, inject thermosetting material into the chamber and maintain pressure to complete thermosetting;

[0043] S4: After thermosetting, the motor drives in reverse, the upper cover 14 rises, and through the lifting belt 22 and the traction rope 23, it separates into fins with the combination plate 21, and guides the cold air laterally. After absorbing heat through the gap of the combination plate 21, it blows the air toward the gear and cools it to a stable temperature.

[0044] S5: Continue lifting the cover 14 and the combined plate 21 to detach from the main frame 11 of the equipment. The gear slides down due to gravity and demolds. The combined plate 21 is reset and ready for the next processing.

[0045] During the process of injecting thermosetting material into the cavity and maintaining a preset holding time to complete the thermosetting molding, the thermosetting temperature is controlled in segments, the preset holding time is maintained, and during the holding time, the insert frame 31 continuously applies a lateral constraint force to the assembly plate 21, and cold air is introduced laterally. The cold air absorbs residual heat through the gap of the assembly plate 21 and is then blown toward the molded gear.

[0046] Working principle: In the gear processing, gear processing material is injected into a thermosetting equipment. After thermosetting, demolding is performed to complete the gear processing. The specific operation is as follows: First, during preparation, different numbers of combination plates 21 are added according to the different specifications of the gear. When the number of combination plates 21 increases, the depth of the mold cavity 25 inside the combination plate 21 will be relatively deeper. At this time, the mold cavity 25 can store more injection molding material. By changing different types of upper cover 14, gears of different lengths can be produced. Then, the combination plates 21 are added... During the process, the combined plates 21 are stacked sequentially and passed through the guide posts 12 to fix their positions. After stacking, each group of combined plates 21 is connected by a traction rope 23. After connecting the combined plates 21, a pressure plate 28 is placed over the upper surface of the combined plates 21, and the chamber is closed by the descent of the upper cover 14. Inside the closed chamber, the drive motor 15 drives the drive screw 18 to rotate. When the drive screw 18 rotates, the transmission gear at the top of the drive screw 18... 16 drive screws rotate synchronously. Through the transmission of gear 16 and belt 17, the rotation of one drive screw 18 drives the other three drive screws 18 to rotate synchronously. The rotation of the drive screws 18 causes the upper cover 14 to descend. When the upper cover 14 descends, it presses against the upper surface of the pressure plate 28. The pressure plate 28 transmits the force to the combined plate 21, making the combined plates 21 fit more tightly together and eliminating gaps. After this operation, the combined plate 21 is positioned between the main frame 11 and the pressure plate 28. To improve the position of the combined plate 21... To improve the fit between the panels and prevent the thermosetting material from overflowing through gaps, the system is equipped with interlocking blocks 29 and sealing grooves 26. Each composite plate 21 has a sealing groove 26 on its upper surface and an interlocking block 29 connected to its bottom surface. When the composite plates 21 are fitted together, the interlocking block 29 is embedded into the sealing groove 26. This increased fit between the composite plates 21 and, since the sealing groove 26 and the interlocking block 29 are arranged around the mold cavity 25, the thermosetting material inside the mold cavity 25 can also be prevented from overflowing, resulting in better molding performance.When the upper cover 14 is pressed onto the upper surface of the pressure plate 28, an insertion frame 31 is embedded inside the upper cover 14. After the insertion frame 31 is embedded inside the upper cover 14, as the pressure continues to decrease, the insertion frame 31 is inserted into the slot 27 opened on the surface of the composite plate 21. The insertion frame 31 is embedded into the slot 27, which increases the constraint on the composite plate 21 and plays a role in stabilizing the composite plate 21. During injection molding, the temperature inside the composite plate 21 rises, causing the composite plate 21 to expand outward. In order to suppress a large degree of expansion, the insertion frame 31 is embedded into the insertion frame. The internal structure of the insert frame 31 restricts the shape of the assembly plate 21, preventing displacement or tilting of the assembly plate 21 during injection molding due to pressure transmission, ensuring that the entire mold cavity 25 maintains a regular shape. It also plays a crucial role in the subsequent thermosetting stage: as the internal temperature of the assembly plate 21 rises, its metal material tends to expand outwards due to thermal expansion. The insert frame 31, embedded in the slot 27, acts as a rigid support, directly limiting the excessive expansion of the assembly plate 21 and preventing dimensional deviations in the mold cavity 25 caused by deformation of the assembly plate 21. This, in turn, avoids overflow or deviations in tooth profile accuracy during the thermosetting process. Furthermore, the engagement of the insert frame 31 and the slot 27 helps to disperse the pressing force applied by the upper cover 14, allowing the pressure to be transmitted more evenly to each assembly plate 21, further improving the overall sealing and structural stability of the mold cavity 25, and providing reliable shape assurance for thermosetting molding. After thermosetting and pressure molding, the drive motor 15 drives the drive screw 18 to rotate. When the drive screw 18 starts rotating, it causes the upper cover 14 to rise. As the upper cover 14 rises, it drives the combined plate 21 to rise via the lifting belt 22. When the first combined plate 21 rises, it supports the pressure plate 28 and rises. Simultaneously, the first combined plate 21, via the traction rope 23, drives the second combined plate 21 to rise, and the second combined plate 21, via the traction rope 23, drives the third combined plate 21 to rise, and so on. As the upper cover 14 rises, each... The combined plates 21 separate, forming a fin-like structure. Lateral ventilation then begins, introducing air through a cooling system. The air passes through the gaps between the combined plates 21 and is blown onto the molded gear until it is completely cooled and demolded. Directly blowing air during cooling would cause the thermoset gear to cool too quickly, leading to deformation. The molding of thermoset gears relies on a resin cross-linking reaction; after the reaction, the material structure solidifies and is fixed, unlike the reversible melting and cooling properties of thermoplastic materials. If the gear is demolded and cooled immediately after thermosetting at 160-180℃, the sudden cooling will cause a drastic temperature difference inside the gear. The surface layer will instantly drop to room temperature while the core remains hot, triggering severe internal stress. This can lead to tooth surface cracking, tooth shape deformation such as tooth thickness deviation, or a decrease in mechanical properties, completely failing to meet the transmission accuracy requirements of the gear pump.To address this issue, during air cooling, air is blown into the surface of the thermoset gear through the combination plate 21. As the air passes through the gaps in the combination plate 21, it heats up before being blown onto the gear surface to cool it. This reduces the impact of temperature differences and eliminates the heat generated by the combination plate 21 itself. The benefits are: in the air cooling process, as the cold air passes through the gaps in the combination plate 21, it first absorbs the residual heat from the previous thermosetting process and heats up before acting on the surface of the thermoset gear. By reducing the temperature difference, the temperature difference between the gear and the airflow is minimized, precisely matching the optimal cooling rate of the thermoset material and completely avoiding [the problem]. The instantaneous temperature difference caused by direct blowing of cold air at room temperature effectively eliminates the risk of micro-cracks and minor deformation of the gear teeth. Simultaneously, it removes residual heat from the composite plate 21, lowering its temperature and preventing prolonged cooling cycles caused by reverse heat transfer from the composite plate 21 to the gear. It also mitigates material fatigue caused by repeated high temperatures in the composite plate 21. Furthermore, the uniform gaps formed after the composite plate 21 is unfolded allow the heated cold air to create an airflow field around the gear, ensuring consistent temperature rise in each gap. This solves the problem of localized overheating caused by traditional unidirectional air cooling and replaces the traditional water-cooling module for handling residual heat from the composite plate 21. During the demolding process, the gear must be thermoset and cooled to a stable structural state. After thermosetting and air cooling, the gear has formed a rigid cross-linked structure with no risk of plastic deformation. The drive motor 15 then lifts the upper cover 14, which, along with the traction rope 23, simultaneously pulls the top composite plate 21 upwards along the guide column 12. As the top-layer assembly plate 21 rises until it is completely detached from the upper surface of the main frame 11, the pre-treated demolding structure on the inner side of the assembly plate 21 plays a crucial role in preventing the gears from sticking to the inner wall of the assembly plate 21. Furthermore, as the assembly plate 21 unfolds, the gears are no longer constrained by the mold cavity 25 and naturally slide down into the collection device below under their own gravity. After the gears have completed demolding, the drive motor 15 continues to drive all the assembly plates 21 to reset and stack, preparing for the next thermosetting process.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
