Description

Technical Field

[0001] The invention relates to the technical field of sheet stacking and stamping, and in particular to a stamping and stacking die and a stamping process for compressor accessories. Background Art

[0002] The compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It sucks low-temperature, low-pressure refrigerant gas from the suction pipe, compresses it through the operation of the motor to drive the piston, and then discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. The motor stator in the motor is the stationary part of the motor. The stator is generally composed of three parts: the stator core, the stator winding, and the frame. The production process of the stator core is mostly to use a high-speed punch to stamp the rolled silicon steel sheets and stack the stamped sheets to complete the production of the stator core.

[0003] Chinese patent publication number CN115990637B discloses "high-speed punching machine and processing technology for motor stator processing", including a punching machine carrier frame, which includes a carrier platform and a support frame body, a mold carrier frame for carrying a stamping lower mold is installed on the carrier platform, and also includes a stamping power box, an intermittent feeding mechanism and a limit assembly that can be adjustably installed on the support frame body, a stamping mechanism is installed inside the stamping power box, and the stamping mechanism includes a driving assembly and multiple groups of continuous pressing stamping assemblies. The high-speed punching machine for processing the motor stator can greatly reduce the stamping time interval of the silicon steel sheet and improve the production efficiency of the motor stator through the linkage cooperation between the components during the processing of stamping and laminating the motor stator, and at the same time, when stamping the silicon steel sheet, it can greatly ensure the quality of the stamping sheet after stamping, and greatly improve the quality of the motor stator after lamination, and has strong applicability.

[0004] In this scheme, during the stamping and lamination process of the motor stator, the silicon steel sheets required for the production of the motor stator can be pressed and then stamped by the cooperation of the driving component and multiple groups of continuous pressing and stamping components. Not only does it not require the cooperation of other auxiliary equipment, but it can also stamp the silicon steel sheets at high speed. At the same time, when the silicon steel sheets are pressed for stamping, the quality of the stamped sheets is higher, and the quality of the motor stator after lamination is higher. In the process of stamping and laminating the silicon steel sheets, the driving component, the intermittent adjustment component and the feeding component are linked to each other, and the silicon steel sheets can be continuously intermittently pressed. The feeding operation is carried out, but for the process of stacking and stamping silicon steel sheets, the rivet point fixing method is still one of the mainstream processes. However, the silicon steel sheet rivet point fixing method is used. When this method is used for fixing, the weight borne by each rivet point is limited. For large motors, such connection strength may not be sufficient. In operation, it is preferred to lift it from below to prevent the silicon steel sheet from separating. This leads to certain limitations in the handling of silicon steel sheets. Therefore, a stamping and stacking mold and a stamping process for compressor accessories are proposed to solve the above-mentioned problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a stamping and laminating die and stamping process for compressor accessories, which solves the problem that the weight borne by each rivet point is limited and such connection strength may not be sufficient for large motors.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A stamping and laminating die and stamping process for compressor accessories, comprising a body, wherein a laminating die assembly platform is connected inside the body;

[0008] A glue coating mechanism is provided above the stacking die set platform for coating the steel strip with glue;

[0009] A slicing mechanism is provided above the stacking die set table for slicing the steel strip;

[0010] A stacking mechanism is provided above the stacking die assembly platform for stacking steel sheets.

[0011] Preferably, the glue coating mechanism includes a glue coating roller, and the top of the stacking module platform is rotatably connected to the glue coating roller through a support plate, and the two groups of glue coating rollers are arranged up and down and contact each other. When the steel belt passes through the position between the glue coating rollers, a clamping space will be formed between the glue coating rollers, so that when the steel belt moves, the glue coating rollers will be driven to rotate together through friction. The top of the inner wall of the fuselage is connected to a liquid storage tank, and the liquid storage tank is connected to an infusion tube, and the infusion tube is connected to the inside of the two groups of glue coating rollers through a double-way tube. By arranging the infusion tube below the liquid storage tank and below the double-way tube, it is convenient to inject the inside of the glue coating roller. It is worth mentioning that the steel strip in this scheme uses stainless steel as raw material, because the silicon steel used conventionally contains aluminum, especially excessive (more than 0.5%) silicon steel sheets are too brittle and difficult to process, which can easily lead to self-rivet buckle chipping and high maintenance frequency. By using stainless steel as the overlapping material, compared with silicon steel sheets, stainless steel has stronger tensile properties, which can effectively avoid the occurrence of self-rivet buckle chipping, and the stainless steel material itself has good corrosion resistance and high hardness, which greatly improves the durability of the overlapping parts and effectively reduces the later maintenance costs.

[0012] Preferably, the glue coating roller is composed of a supporting frame, a water seepage sleeve, and a dividing groove. The water seepage sleeve is arranged on the outer wall of the supporting frame. The glue inside the glue coating roller seeps out from the inside of the glue coating roller through the water seepage sleeve due to the squeezing of the glue coating roller and the steel belt, and is evenly coated on the front and back sides of the steel belt. The inner wall of the supporting frame is provided with a dividing groove. The dividing groove provided on the inner wall of the supporting frame of the glue coating roller divides the inside of the glue coating roller into multiple areas, so that the glue can be evenly distributed inside the glue coating roller, avoiding the problem of uneven glue coating caused by the glue always being at the bottom of the inner wall of the glue coating roller.

[0013] Preferably, the slicing mechanism includes a first hydraulic cylinder, which is connected to the top of the inner wall of the fuselage, and the bottom of the first hydraulic cylinder is connected to a first pressure plate, and the bottom of the first pressure plate is connected to a cutting ring. When the steel belt moves over the top of the slip ring, the first hydraulic cylinder drives the first pressure plate to press down, and the cutting ring makes limited contact with the steel belt to slice it during the continuous descent of the first pressure plate to form an annular steel sheet. A first riveting groove is provided at the bottom of the first pressure plate between the cutting rings to form a riveted depression on the steel sheet.

[0014] Preferably, an annular groove is provided on the top of the stacking module platform below the first pressure plate, a slip ring is slidably connected to the inner wall of the annular groove, a riveted top block is connected to the bottom of the annular groove, and the riveted top block passes through the slip ring and is slidably connected, the position of the riveted top block corresponds one to one with the first riveted groove, during the pressing down process of the first pressure plate, the slip ring will sink to expose the riveted top block, and then after the first pressure plate is stamped down, the riveted top block cooperates with the first riveted groove, so that the corresponding positions on the upper and lower surfaces of the steel sheet are printed with depressions and protrusions for riveting.

[0015] Preferably, the top of the stacking module platform is provided with sliding grooves on both sides of the annular groove, the bottom of the sliding groove is connected to the bottom of the annular groove, the bottom two sides of the annular groove are slidably connected with arc-shaped gaskets, and the arc-shaped gaskets extend to the inside of the slide groove, the top of the arc-shaped gasket is connected with a magnetic push block, and the magnetic push block is slidably connected to the inner wall of the slide groove, the two sides of the inner wall of the slide groove are respectively connected with limited blocks, the magnetic push block corresponds to the position of the limit block and the inner wall of the limit groove is slidably connected to the limit block, the side of the inner wall of the slide groove corresponding to the magnetic push block is connected with a magnetic block, and the magnetic block and the side corresponding to the magnetic push block are of the same polarity, when the first pressure plate rises and leaves the steel sheet, the steel sheet is clamped on the riveted top block due to its bottom depression, and the first pressure plate will not be lifted, and the During the subsequent continuous rising process of a pressure plate, as the pressure block leaves the magnetic push block, the magnetic push block, which loses the external force, will generate a certain repulsive force because the magnetic block and the side corresponding to the magnetic push block are of the same pole, pushing the magnetic push block away, so that the arc-shaped gasket connected under the magnetic push block is reinserted under the slip ring, so that the slip ring is lifted and reset again. Pressure blocks are respectively connected to the positions corresponding to the magnetic push blocks on both sides of the first pressure plate. The first pressure plate will continue to descend and drive the pressure block. When the inclined surface of the pressure block contacts and squeezes the magnetic push block, the magnetic push block is relatively limited by the connection relationship between the limit groove and the limit block, so that when the magnetic push block slides, it drives the arc-shaped gasket to be pulled out from under the slip ring. In the subsequent process of pressing down the first pressure plate, since the slip ring lacks the arc-shaped gasket, the slip ring will sink and expose the riveted top block.

[0016] Preferably, the stacking mechanism includes a second hydraulic cylinder, which is connected to the top of the inner wall of the fuselage, the bottom of the second hydraulic cylinder is connected to a second pressure plate, and the bottom of the second pressure plate is provided with a second riveting groove, the stacking die set is provided with a cylindrical groove at a position below the second pressure plate, the bottom of the inner wall of the cylindrical groove is connected to a third hydraulic cylinder, the top of the third hydraulic cylinder is connected to a sliding plate, and the sliding plate is slidably connected to the inner wall of the cylindrical groove, and each time the intermittent feeding device drives the annular steel sheet to move, the third hydraulic cylinder will drive The upper sliding plate drops a certain distance so that the annular steel sheet has enough space to sink, so that each subsequent stacking of the annular steel sheets will be in the cylindrical groove, avoiding the stacking of the annular steel sheets during stamping. A riveted bump is connected to the top of the sliding plate. When the annular steel sheet is pushed to the position on the sliding plate, the annular steel sheet will sink. Since a riveted bump is provided above the sliding plate, the riveted bump will be embedded in the depression at the bottom of the annular steel sheet. A discharge port is provided on the front of the cylindrical groove, and the discharge port extends to the outside of the stacking die set. The discharge port is used to discharge the stamped stacked parts.

[0017] Preferably, an air cavity is provided on the back side of the inner wall of the cylindrical groove, and a push plate is slidably connected to the inner wall of the air cavity, through which the stamped and stacked parts that have been stacked are pushed from the cylindrical groove into the discharge port and discharged through the inclined surface of the discharge port to complete the processing, an air inlet hole is provided on the top of the air cavity, a piston rod is connected to the top of the inner wall of the fuselage, and the inside of the piston rod is connected to the air inlet hole through an air pipe, the inside of the piston rod is connected to a spring, a pressure rod is connected to the bottom of the piston rod, and a push rod is connected to the outer wall of the telescopic end of the second hydraulic cylinder corresponding to the position of the pressure rod, when the stacking thickness of the annular steel sheet reaches the required requirement, after the second hydraulic cylinder drives the second pressure plate to complete the last stamping, the second hydraulic cylinder lifts the second pressure plate to increase the drive to drive the push rod to rise and contact the pressure rod, thereby squeezing the piston rod, so that the piston rod is squeezed and injected into the air cavity from the air pipe through the air inlet hole, and the injected gas will squeeze the push plate.

[0018] Preferably, the top of the stacking module platform is connected to a limit plate at the right side of the gluing mechanism, and the steel belt passing between the glue coating rollers will pass under the limit plate. The limit plate set at an angle will smooth the steel belt and scrape off excess glue. The top of the stacking module platform is connected to guide plates on both sides between the limit plate and the slicing mechanism, and the steel belt is guided into the slicing mechanism via the guide plates. A discharge hole is provided at the top of the stacking module platform between the gluing mechanism and the slicing mechanism. When the intermittent feeding device drives the steel belt to move to the discharge hole, the steel sheet will be driven to move together because it is still in the steel belt cutting position, and the circular waste in the center of the circular steel sheet will fall into the discharge hole and be discharged.

[0019] The following steps are involved:

[0020] Step 1: Use the intermittent feeding device set outside the machine body, feed the steel strip into the gluing mechanism inside the machine body with the same feeding distance each time and the moving distance should meet the size of the cut steel sheet;

[0021] The second step is that the steel belt passes through the position between the two groups of glue rollers in the glue coating mechanism. Since the outer wall of the glue coating roller is provided with a water seepage sleeve, when the steel belt passes through the glue coating roller, a clamping space will be formed between the glue coating rollers, so that when the steel belt moves, the friction force will drive the glue coating roller to rotate together. The glue inside the glue coating roller is squeezed by the glue coating roller and the steel belt, and seeps out from the inside of the glue coating roller through the water seepage sleeve through the support frame, and is evenly coated on the front and back sides of the steel belt. The dividing grooves provided on the inner wall of the glue coating roller support frame divide the inside of the glue coating roller into multiple areas, so that the glue can be evenly distributed inside the glue coating roller, avoiding the problem of uneven glue coating caused by the glue always being at the bottom of the inner wall of the glue coating roller. In addition, this method of applying glue in advance can increase the firmness of the connection between the steel sheets when the steel sheets are subsequently stacked by riveting. The dual fixing method of riveting and glue can effectively avoid the separation of the steel sheets caused by insufficient strength of the connection between the steel sheets when carrying some heavy steel sheet stamping and stacking parts.

[0022] Step 2: The steel strip passing through the glue coating rollers will pass under the limit plate. The limit plate, which is set obliquely, will smooth the steel strip and scrape off the excess adhesive. The steel strip will then be guided by the guide plate into the position of the slicing mechanism.

[0023] Step 3: When the steel belt moves over the top of the slip ring, the first hydraulic cylinder drives the first pressure plate to press down. During the continuous descent of the first pressure plate, the cutting ring contacts the steel belt to slice the steel belt to form an annular steel sheet. At this time, the first pressure plate will continue to descend to drive the pressure block. When the inclined surface of the pressure block contacts and squeezes the magnetic push block, the magnetic push block is relatively limited by the connection relationship between the limit groove and the limit block, so that the magnetic push block drives the arc-shaped gasket to be pulled out from under the slip ring when sliding. In the subsequent process of pressing down the first pressure plate, since the slip ring lacks the arc-shaped gasket, the slip ring will sink to expose the riveted top block, and then after being stamped down by the first pressure plate, the riveted top block cooperates with the first riveted groove, so that the upper and lower surfaces of the steel sheet are printed with depressions and protrusions for riveting.

[0024] Step 4: After the depressions and protrusions are printed at the riveted positions on the upper and lower surfaces of the steel sheet, the first hydraulic cylinder drives the first pressure plate to lift. When the first pressure plate rises and leaves the steel sheet, the steel sheet is stuck on the riveted top block due to the depression at the bottom thereof, and the first pressure plate will not lift it. In the subsequent continuous rising process of the first pressure plate, the pressure block leaves the magnetic push block, and the magnetic push block loses the external force. Since the magnetic block and the side corresponding to the magnetic push block are of the same pole, a certain repulsive force will be generated, pushing the magnetic push block away, so that the arc-shaped gasket connected under the magnetic push block is reinserted under the slip ring, so that the slip ring is lifted and reset again, and the steel sheet above the riveted top block is squeezed out. At this time, the intermittent feeding equipment drives the steel belt to move to the discharge hole. Since the steel sheet is still in the steel belt cutting position, it will be driven to move together, and the circular waste in the center of the annular steel sheet will fall into the discharge hole for discharge.

[0025] Step 5. When the intermittent feeding equipment pushes the annular steel sheet in the steel belt to the position on the sliding plate in the overlapping mechanism, the annular steel sheet will sink. Since a riveting protrusion is arranged above the sliding plate, the riveting protrusion will be embedded in the depression at the bottom of the annular steel sheet. Before each intermittent feeding equipment drives the annular steel sheet to move, the third hydraulic cylinder will drive the upper sliding plate to drop a certain distance, so that the annular steel sheet has enough sinking space, so that each subsequent stacking of annular steel sheets is in the cylindrical groove, so as to avoid the stacked annular steel sheets from shifting during stamping, and the second hydraulic cylinder above drives the second pressure plate to stamp the stacked annular steel sheets, so that the protrusions and depressions above and below the annular steel sheets are riveted to each other to complete the splicing, so that each time the steel sheets are stacked, stamping and riveting are performed. After stamping, the second hydraulic cylinder drives the second pressure plate to lift, and the third hydraulic cylinder drives the upper sliding plate to drop. Since the surface of the steel sheet is coated with adhesive in advance, the strength of the connection is greatly improved, so that the radial and axial load-bearing capacity of the steel sheet stamping and overlapping parts are greatly improved;

[0026] Step six, when the overlapping thickness of the annular steel sheets reaches the required requirement, after the second hydraulic cylinder drives the second pressure plate to complete the last stamping, the second hydraulic cylinder lifts the second pressure plate to increase the drive push rod to rise and contact the pressure rod, and squeezes the piston rod, so that the piston rod is squeezed from the air pipe through the air inlet hole into the air cavity, and the injected gas will squeeze the push plate, and the stamped and overlapped parts that have been overlapped will be pushed from the cylindrical groove into the discharge port through the push plate, and discharged through the inclined surface of the discharge port. The processing has been completed. After the stamped and overlapped parts are discharged, the second hydraulic cylinder moves to the position originally prepared for stamping. After the pressure rod loses the push rod extrusion, the piston rod is reset under the action of the internal spring tension, and the air in the air cavity is extracted to reset the push plate, and the third hydraulic cylinder will also drive the sliding plate to reset in preparation for subsequent stamping and lamination, so as to achieve the purpose of continuous and efficient processing.

[0027] Compared with the prior art, the present invention provides a stamping and laminating die and stamping process for compressor accessories, which has the following beneficial effects:

[0028] 1. The stamping and laminating die and stamping process of the compressor parts, through the setting of the gluing mechanism, by applying the adhesive in advance, when the steel sheets are subsequently laminated by riveting, the firmness of the connection between the steel sheets can be increased, so that the radial and axial bearing capacity of the steel sheet stamping and laminating parts are greatly improved. The dual fixing method of riveting and gluing can effectively avoid the separation of the steel sheets caused by insufficient strength of the connection between the steel sheets when carrying some heavy steel sheet stamping and laminating parts. In addition, the steel strip in this scheme uses stainless steel as the raw material. Because the silicon steel used conventionally contains aluminum, especially the excessive (more than 0.5%) silicon steel sheet is too brittle and difficult to process, which easily leads to self-rivet buckle chipping and high maintenance frequency. By using stainless steel material as the laminating material, compared with silicon steel sheet, stainless steel material has stronger tensile performance, which can effectively avoid the self-rivet buckle chipping, and the stainless steel material itself has good corrosion resistance and high hardness, which greatly improves the durability of the laminating parts and effectively reduces the later maintenance cost.

[0029] 2. The stamping and laminating die and stamping process of the compressor parts adopt a two-stage stamping method through a slicing mechanism. One stage is stamping and slicing, and the second stage is stamping and printing riveting patterns, so as to facilitate slicing of the steel strip and stamping of riveting depressions and protrusions in one action, which can effectively improve the processing efficiency.

[0030] 3. The stamping and stacking die and stamping process of the compressor accessories use a stacking mechanism to stack and stamp the cut and printed annular steel sheets with rivet patterns, and the stacking and stamping is performed in a way of stacking one sheet at a time, ensuring the tightness of the riveting between each steel sheet in turn to improve the efficiency of the stacking and stamping, and to ensure the overall quality of the stamped stacked parts. The completed stamped stacked parts are discharged through a power-driven push plate that is lifted after stamping, and a complete set of processing procedures is formed in sequence, which greatly shortens the processing time and improves efficiency.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a stamping and laminating die and stamping process for compressor parts include a body 1, a laminating die set 21 is connected inside the body 1, a gluing mechanism 24 is arranged above the laminating die set 21 for gluing steel strips, a slicing mechanism 25 is arranged above the laminating die set 21 for slicing steel strips, a laminating mechanism 27 is arranged above the laminating die set 21 for laminating steel sheets, the gluing mechanism 24 includes a gluing roller 244, and the laminating die set 21 includes a laminating roller 245. The top of the platform 21 is rotatably connected to a glue coating roller 244 through a support plate 243. The two sets of glue coating rollers 244 are arranged up and down and contact each other. When the steel belt passes through the position between the glue coating rollers 244, a clamping space is formed between the glue coating rollers 244, so that when the steel belt moves, the glue coating rollers 244 are driven to rotate together through friction. The top of the inner wall of the fuselage 1 is connected to a liquid storage tank 241, and the liquid storage tank 241 is connected to an infusion tube 242, and the infusion tube 242 is connected to the double-channel pipe 2 45 is connected to the inside of the two groups of glue rollers 244, and the glue rollers 244 are conveniently injected with glue by arranging a liquid infusion pipe 242 and a double-way pipe 245 below the liquid storage tank 241. The glue rollers 244 are composed of a support frame 2441, a water seepage sleeve 2442, and a dividing groove 2443. The water seepage sleeve 2442 is sleeved on the outer wall of the support frame 2441. The glue inside the glue rollers 244 is squeezed by the glue rollers 244 and the steel belt, and then flows out from the support frame 2441. The glue seeps out from the inside of the glue coating roller 244 through the water seepage sleeve 2442 and is evenly coated on the front and back sides of the steel belt. The inner wall of the supporting frame 2441 is provided with a dividing groove 2443. The dividing groove 2443 provided on the inner wall of the supporting frame 2441 of the glue coating roller 244 divides the inside of the glue coating roller 244 into multiple areas, so that the glue can be evenly distributed inside the glue coating roller 244, avoiding the problem of uneven glue coating caused by the glue always being at the bottom of the inner wall of the glue coating roller 244.

[0046] It is worth mentioning that the steel strip in this scheme uses stainless steel as raw material, because the silicon steel used conventionally contains aluminum, especially excessive (more than 0.5%) silicon steel sheets are too brittle and difficult to process, which can easily lead to self-rivet buckle chipping and high maintenance frequency. By using stainless steel as the overlapping material, compared with silicon steel sheets, stainless steel has stronger tensile properties, which can effectively avoid the occurrence of self-rivet buckle chipping, and the stainless steel material itself has good corrosion resistance and high hardness, which greatly improves the durability of the overlapping parts and effectively reduces the subsequent maintenance costs.

[0047] In this embodiment, an infusion tube 242 and a two-way tube 245 are arranged below the liquid storage tank 241 to facilitate the injection of glue into the glue coating roller 244. When the steel belt passes through the position between the glue coating rollers 244, a clamping space is formed between the glue coating rollers 244, so that when the steel belt moves, the glue coating roller 244 is driven to rotate together through friction. The glue inside the glue coating roller 244 is squeezed by the glue coating roller 244 and the steel belt, and seeps out from the inside of the glue coating roller 244 through the water seepage sleeve 2442 from the support frame 2441 and is evenly coated on the front and back sides of the steel belt. The dividing groove 2443 opened on the inner wall of the support frame 2441 of the glue coating roller 244 divides the inside of the glue coating roller 244 into multiple areas, so that the glue can be evenly distributed inside the glue coating roller 244, avoiding the problem of uneven glue coating caused by the glue always being at the bottom of the inner wall of the glue coating roller 244. Example 2

[0048] like Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8As shown, the slicing mechanism 25 includes a first hydraulic cylinder 251, which is connected to the top of the inner wall of the fuselage 1, and a first pressure plate 252 is connected to the bottom of the first hydraulic cylinder 251, and a cutting ring 2521 is connected to the bottom of the first pressure plate 252. When the steel belt moves over the top of the slip ring 254, the first hydraulic cylinder 251 drives the first pressure plate 252 to press down, and the cutting ring 2521 makes limited contact with the steel belt to slice the steel belt during the continuous descent of the first pressure plate 252 to form an annular steel sheet. A first riveting groove 2522 is provided at the bottom of the first pressure plate 252 between the cutting rings 2521, which is used to form a riveted depression on the top of the steel sheet. An annular groove 253 is provided at the top of the stacking die set 21 below the first pressure plate 252. The inner wall of 253 is slidably connected with a slip ring 254, and the bottom of the annular groove 253 is connected with a riveted top block 255, and the riveted top block 255 penetrates the slip ring 254 and is slidably connected. The position of the riveted top block 255 corresponds to the first riveted groove 2522. During the downward pressing process of the first pressure plate 252, the slip ring 254 will sink to expose the riveted top block 255, and then after the first pressure plate 252 is stamped, the riveted top block 255 cooperates with the first riveted groove 2522, so that the corresponding positions on the upper and lower surfaces of the steel sheet are printed with concave and convex for riveting. The top of the stacking module platform 21 is located on both sides of the annular groove 253 and is respectively provided with sliding grooves 256. The bottom of the sliding groove 256 is connected to the bottom of the annular groove 253, and the bottom of the annular groove 253 is slidably connected with arc-shaped gaskets on both sides. 2561, and the arc-shaped gasket 2561 extends to the inside of the slide 256, the top of the arc-shaped gasket 2561 is connected with a magnetic push block 2562, and the magnetic push block 2562 is slidably connected to the inner wall of the slide 256, and the two sides of the inner wall of the slide 256 are respectively connected to the limit blocks 25622, and the magnetic push block 2562 is provided with a limit groove 25621 at the position corresponding to the limit block 25622, and the inner wall of the limit groove 25621 is slidably connected to the limit block 25622, and the inner wall of the limit groove 25621 is connected to the limit block 25622, and the side of the inner wall of the slide 256 corresponding to the magnetic push block 2562 is connected with a magnetic block 2563, and the side corresponding to the magnetic block 2563 and the magnetic push block 2562 is the same pole, when the first pressure plate 252 rises and leaves the steel sheet, the steel sheet is stuck on the riveted top block 25 due to the depression at its bottom 5, the first pressure plate 252 will not be lifted. In the subsequent continuous rising process of the first pressure plate 252, since the pressure block 2523 leaves the magnetic push block 2562, the magnetic push block 2562 without external force will generate a certain repulsive force because the magnetic block 2563 and the side corresponding to the magnetic push block 2562 are of the same pole, and the magnetic push block 2562 will be pushed away. The arc-shaped gasket 2561 connected below the magnetic push block 2562 is reinserted under the slip ring 254, so that the slip ring 254 is lifted and reset again. The positions corresponding to the magnetic push blocks 2562 on both sides of the first pressure plate 252 are respectively connected with pressure blocks 2523. The first pressure plate 252 will continue to descend to drive the pressure block 2523. When the inclined surface of the pressure block 2523 contacts and squeezes the magnetic push block 2562,The magnetic push block 2562 is relatively limited by the connection between the limit groove 25621 and the limit block 25622, so that when the magnetic push block 2562 slides, the arc-shaped gasket 2561 is pulled out from under the slip ring 254. In the subsequent process of the first pressure plate 252 pressing down, the slip ring 254 will sink and expose the riveted top block 255 because the slip ring 254 lacks the arc-shaped gasket 2561.

[0049] In this embodiment, when the steel belt moves over the top of the slip ring 254, the first hydraulic cylinder 251 drives the first pressure plate 252 to press down. During the continuous descending process of the first pressure plate 252, the cutting ring 2521 contacts the steel belt to slice the steel belt to form an annular steel sheet. At this time, the first pressure plate 252 will continue to descend to drive the pressing block 2523. When the inclined surface of the pressing block 2523 contacts and squeezes the magnetic push block 2562, the magnetic push block 2562 is pressed by the connection relationship between the limiting groove 25621 and the limiting block 25622. The push block 2562 is relatively limited, so that when the magnetic push block 2562 slides, it drives the arc gasket 2561 to be pulled out from under the slip ring 254. In the subsequent process of the first pressure plate 252 pressing down, since the slip ring 254 lacks the arc gasket 2561, the slip ring 254 will sink to expose the riveted top block 255, and then after being stamped down by the first pressure plate 252, the riveted top block 255 cooperates with the first riveted groove 2522, so that the upper and lower surfaces of the steel sheet are printed with depressions and protrusions for riveting. Example 3

[0050] like Figure 2 , Figure 3 , Fig. 9 , Fig.10As shown in the figure, the stacking mechanism 27 includes a second hydraulic cylinder 271, which is connected to the top of the inner wall of the fuselage 1, and the bottom of the second hydraulic cylinder 271 is connected to a second pressure plate 272, and the bottom of the second pressure plate 272 is provided with a second riveting groove 2721, and the stacking die set 21 is provided with a cylindrical groove 273 below the second pressure plate 272, and the bottom of the inner wall of the cylindrical groove 273 is connected to a third hydraulic cylinder 274, and the top of the third hydraulic cylinder 274 is connected to a sliding plate 275, and the sliding plate 275 is slidably connected to the inner wall of the cylindrical groove 273. Before the intermittent feeding device drives the annular steel sheet to move, the third hydraulic cylinder 274 will drive the upper sliding plate 275 to drop a certain distance, so that the annular steel sheet has enough sinking space, so that each subsequent stacking of the annular steel sheet When the annular steel sheets are in the cylindrical groove 273, they are prevented from being offset when the superimposed annular steel sheets are stamped. The top of the sliding plate 275 is connected with a rivet protrusion 2751. When the annular steel sheet is pushed to the position on the sliding plate 275, the annular steel sheet will sink. Since the rivet protrusion 2751 is arranged above the sliding plate 275, the rivet protrusion 2751 will be embedded in the depression at the bottom of the annular steel sheet. A discharge port 276 is provided on the front of the cylindrical groove 273, and the discharge port 276 extends to the outside of the stacking die set 21. The discharge port 276 is used to discharge the stamped stacked parts. An air cavity 2761 is provided on the back of the inner wall of the cylindrical groove 273. The inner wall of the air cavity 2761 is slidably connected with a push plate 2762. The stamped stacked parts completed by the stacking are pushed from the cylindrical groove 273 into the discharge port 2762 through the push plate 2762. 76, discharged through the inclined surface of the discharge port 276, the processing has been completed, the top of the air cavity 2761 is provided with an air inlet 2763, the top of the inner wall of the fuselage 1 is connected with a piston rod 2765, and the inside of the piston rod 2765 is connected with the air inlet 2763 through the air pipe 2764, the inside of the piston rod 2765 is connected with a spring, the bottom of the piston rod 2765 is connected with a pressure rod 2767, and the outer wall of the telescopic end of the second hydraulic cylinder 271 is connected with a push rod 2766 corresponding to the position of the pressure rod 2767. When the overlapping thickness of the annular steel sheet reaches the required requirement, after the second hydraulic cylinder 271 drives the second pressure plate 272 to complete the last stamping, the second hydraulic cylinder 271 lifts the second pressure plate 272 to increase the drive push rod 2766 to rise and contact the pressure rod 2767, and the piston rod 27 65 is squeezed, so that the piston rod 2765 is squeezed and injected into the air cavity 2761 from the air pipe 2764 through the air inlet 2763, and the injected gas will squeeze the push plate 2762. The top of the stacking module platform 21 is connected to the limit plate 22 at the right side of the glue coating mechanism 24. The steel belt passing through between the glue coating rollers 244 will pass from the bottom of the limit plate 22. The limit plate 22 set obliquely will smooth the steel belt and scrape off the excess adhesive. The top of the stacking module platform 21 is connected to the positions on both sides between the limit plate 22 and the slicing mechanism 25. The steel belt is then guided into the position of the slicing mechanism 25 through the guide plate 23. The top of the stacking module platform 21 is opened at the position between the glue coating mechanism 24 and the slicing mechanism 25. A discharge hole 26 is provided.When the intermittent feeding device drives the steel strip to move to the discharge hole 26, the steel sheet will be driven to move together because it is still inside the steel strip cutting position, and the circular waste in the center of the annular steel sheet will fall into the discharge hole 26 for discharge.

[0051] In this embodiment, when the intermittent feeding device pushes the annular steel sheet in the steel belt to the position on the slide plate 275 in the overlapping mechanism 27, the annular steel sheet will sink. Since a riveted protrusion 2751 is arranged above the slide plate 275, the riveted protrusion 2751 will be embedded in the depression at the bottom of the annular steel sheet, and each time the intermittent feeding device drives the annular steel sheet to move, the third hydraulic cylinder 274 will drive the upper slide plate 275 to drop a certain distance, so that the annular steel sheet has enough sinking space, so that each subsequent stacking of annular steel sheets is in the cylindrical groove 273, avoiding the overlapping of the annular steel sheets during stamping. The shaped steel sheets are offset, and the second hydraulic cylinder 271 above drives the second pressure plate 272 to punch the stacked annular steel sheets, so that the upper and lower protrusions and depressions of the annular steel sheets are riveted to each other to complete the splicing. In this way, each time the steel sheets are stacked, they are punched and riveted. After punching, the second hydraulic cylinder 271 drives the second pressure plate 272 to lift, and the third hydraulic cylinder 274 drives the upper sliding plate 275 to descend. Moreover, since the surface of the steel sheets is coated with glue in advance, the strength of the connection is greatly improved, so that the radial and axial bearing capacity of the steel sheet stamping stacking parts are greatly improved. Example 4

[0052] like Figure 1-Figure 12 As shown, the following steps are included:

[0053] Step 1: The steel strip is fed into the gluing mechanism 24 in the body 1 through an intermittent feeding device arranged outside the body 1, with the feeding distance being the same each time and the moving distance being sufficient to meet the size of the steel sheet to be cut;

[0054] Step 2: The steel belt passes through the position between the two groups of glue rollers 244 in the glue coating mechanism 24. Since the outer wall of the glue coating roller 244 is provided with a water seepage sleeve 2442, when the steel belt passes through the glue coating roller 244, a clamping space is formed between the glue coating rollers 244, so that when the steel belt moves, the glue coating roller 244 is driven to rotate together by friction. The glue inside the glue coating roller 244 is squeezed by the glue coating roller 244 and the steel belt, and seeps out from the inside of the glue coating roller 244 through the water seepage sleeve 2442 from the support frame 2441 and is evenly coated on the front and back sides of the steel belt, and the inner wall of the support frame 2441 of the glue coating roller 244 is opened. The dividing groove 2443 divides the inside of the glue roller 244 into multiple areas, so that the glue is evenly distributed inside the glue roller 244, avoiding the problem of uneven glue coating caused by the glue always being at the bottom of the inner wall of the glue roller 244. In addition, by applying the glue in advance, the firmness of the connection between the steel sheets can be increased when the steel sheets are subsequently stacked by riveting. The dual fixing method of riveting and glue can effectively avoid the separation of the steel sheets due to insufficient strength of the connection between the steel sheets when carrying some heavy steel sheet stamping stacked parts.

[0055] Step 2: The steel strip passing through the glue coating rollers 244 will pass under the limit plate 22. The limit plate 22, which is set obliquely, will smooth the steel strip and scrape off the excess adhesive. The steel strip will then be guided by the guide plate 23 to enter the position of the slicing mechanism 25.

[0056] Step 3: When the steel belt moves over the top of the slip ring 254, the first hydraulic cylinder 251 drives the first pressure plate 252 to press down. During the continuous descent of the first pressure plate 252, the cutting ring 2521 contacts the steel belt to slice the steel belt to form an annular steel sheet. At this time, the first pressure plate 252 will continue to descend to drive the pressing block 2523. When the inclined surface of the pressing block 2523 contacts and squeezes the magnetic push block 2562, the magnetic push block 2562 is pressed by the connection relationship between the limit groove 25621 and the limit block 25622. The block 2562 is relatively limited, so that when the magnetic push block 2562 slides, the arc-shaped gasket 2561 is pulled out from under the slip ring 254. In the subsequent process of the first pressure plate 252 pressing down, since the slip ring 254 lacks the arc-shaped gasket 2561, the slip ring 254 will sink to expose the riveted top block 255, and then after the first pressure plate 252 is stamped down, the riveted top block 255 cooperates with the first riveted groove 2522, so that the upper and lower surfaces of the steel sheet are printed with concave and convex for riveting;

[0057] Step 4: After the depressions and protrusions are printed at the riveted positions on the upper and lower surfaces of the steel sheet, the first hydraulic cylinder 251 drives the first pressure plate 252 to lift. When the first pressure plate 252 rises and leaves the steel sheet, the steel sheet is stuck on the riveted top block 255 due to the depression at the bottom thereof, and the first pressure plate 252 is not lifted. During the subsequent continuous rising process of the first pressure plate 252, the pressure block 2523 leaves the magnetic push block 2562, and the magnetic push block 2562 loses the external force. Due to the magnetic block 2563 and the magnetic push block 2562, the magnetic block 2563 and the magnetic push block 2562 are in contact with each other. The corresponding side is of the same pole, which will generate a certain repulsive force, pushing the magnetic push block 2562 away, so that the arc-shaped gasket 2561 connected below the magnetic push block 2562 is reinserted under the slip ring 254, so that the slip ring 254 is lifted and reset again, and the steel sheet above the riveted top block 255 is squeezed out. At this time, the intermittent feeding device drives the steel belt to move to the discharge hole 26. Since the steel sheet is still inside the steel belt cutting position, it will be driven to move together, and the circular waste in the center of the annular steel sheet will fall into the discharge hole 26 for discharge;

[0058] Step 5. When the intermittent feeding device pushes the annular steel sheet in the steel belt to the position on the slide plate 275 in the overlapping mechanism 27, the annular steel sheet will sink. Since a riveted protrusion 2751 is arranged above the slide plate 275, the riveted protrusion 2751 will be embedded in the depression at the bottom of the annular steel sheet. Before each intermittent feeding device drives the annular steel sheet to move, the third hydraulic cylinder 274 will drive the upper slide plate 275 to drop a certain distance, so that the annular steel sheet has enough sinking space, so that each subsequent stacking of annular steel sheets is in the cylindrical groove 273, avoiding the overlapping of annular steel sheets during stamping. The steel sheets are offset, and the second hydraulic cylinder 271 above drives the second pressure plate 272 to punch the stacked annular steel sheets, so that the protrusions and depressions on the upper and lower annular steel sheets are riveted to each other to complete the splicing, so that each time the steel sheets are stacked, they are punched and riveted. After punching, the second hydraulic cylinder 271 drives the second pressure plate 272 to lift, and the third hydraulic cylinder 274 drives the upper sliding plate 275 to descend. In addition, since the surface of the steel sheets is coated with adhesive in advance, the strength of the connection is greatly improved, so that the radial and axial load-bearing capacity of the steel sheet stamping stack is greatly improved;

[0059] Step 6: When the thickness of the annular steel sheet stacking reaches the required requirement, after the second hydraulic cylinder 271 drives the second pressure plate 272 to complete the last stamping, the second hydraulic cylinder 271 lifts the second pressure plate 272 to increase the push rod 2766 to rise and contact the pressure rod 2767, and squeezes the piston rod 2765, so that the piston rod 2765 is squeezed from the air pipe 2764 through the air inlet 2763 into the air cavity 2761, and the injected gas squeezes the push plate 2762, and the stamping stacking completed by the push plate 2762 The parts are pushed from the cylindrical groove 273 into the discharge port 276 and discharged through the inclined surface of the discharge port 276. The processing is completed. After the stamped and overlapped parts are discharged, the second hydraulic cylinder 271 moves to the position originally prepared for stamping. After the pressure rod 2767 loses the squeezing of the push rod 2766, the piston rod 2765 is reset under the action of the internal spring tension, and the air in the air cavity 2761 is extracted to reset the push plate 2762. The third hydraulic cylinder 274 will also drive the sliding plate 275 to reset in preparation for subsequent stamping and overlapping, so as to achieve the purpose of continuous and efficient processing.

5. A stamping process for compressor parts, applied to the stamping and laminating die of any compressor part according to any one of claims 1 to 4, characterized in that: The following steps are involved: Step 1: The steel strip is fed into the gluing mechanism (24) in the machine body (1) through an intermittent feeding device provided outside the machine body (1), with the feeding distance being the same each time and the moving distance being sufficient to meet the size of the steel sheet to be cut; Step 2: The steel belt passes through the position between the two groups of glue coating rollers (244) in the glue coating mechanism (24). Since the outer wall of the glue coating roller (244) is provided with a water seepage sleeve (2442), when the steel belt passes through the glue coating roller (244), a clamping space is formed between the glue coating rollers (244), so that when the steel belt moves, the glue coating rollers (244) are driven to rotate together by friction. The glue inside the glue coating roller (244) is squeezed by the glue coating roller (244) and the steel belt, and seeps out from the inside of the glue coating roller (244) through the water seepage sleeve (2442) and is evenly coated on the front and back sides of the steel belt, and the glue coating roller (244) support skeleton The dividing grooves (2443) formed on the inner wall of the (2441) divide the inside of the glue coating roller (244) into a plurality of areas, so that the glue can be evenly distributed inside the glue coating roller (244), thereby preventing the glue from always being at the bottom of the inner wall of the glue coating roller (244) and causing the glue to be unevenly applied. In addition, by applying the glue in advance, the firmness of the connection between the steel sheets can be increased when the steel sheets are subsequently stacked by riveting. The dual fixing method of riveting and gluing can effectively prevent the separation of the steel sheets due to insufficient strength of the connection between the steel sheets when transporting some heavy steel sheet stamping stacked parts. Step 2: the steel strip passing between the glue coating rollers (244) will pass under the limit plate (22), the limit plate (22) being inclined will smooth the steel strip and scrape off the excess glue, and the steel strip will then be guided by the guide plate (23) to enter the position of the slicing mechanism (25); Step 3: When the steel belt moves over the top of the slip ring (254), the first hydraulic cylinder (251) drives the first pressure plate (252) to press down. As the first pressure plate (252) continues to descend, the cutting ring (2521) contacts the steel belt to slice it, forming an annular steel sheet. At this time, the first pressure plate (252) will continue to descend and drive the pressing block (2523). When the inclined surface of the pressing block (2523) contacts and squeezes the magnetic push block (2562), the magnetic push block is pressed by the connection relationship between the limit groove (25621) and the limit block (25622). (2562) is relatively limited, so that when the magnetic push block (2562) slides, it drives the arc-shaped gasket (2561) to be pulled out from under the slip ring (254). In the subsequent process of pressing down the first pressure plate (252), since the slip ring (254) lacks the arc-shaped gasket (2561), the slip ring (254) will sink to expose the riveted top block (255), and then after being stamped by the first pressure plate (252), the riveted top block (255) cooperates with the first riveted groove (2522), so that the upper and lower surfaces of the steel sheet are printed with depressions and protrusions for riveting; Step 4: After the depressions and protrusions are printed at the riveted positions on the upper and lower surfaces of the steel sheet, the first hydraulic cylinder (251) drives the first pressure plate (252) to lift up. When the first pressure plate (252) rises and leaves the steel sheet, the steel sheet is stuck on the riveted top block (255) due to the depression at the bottom thereof, and the first pressure plate (252) is not lifted up. In the subsequent continuous rising process of the first pressure plate (252), the pressure block (2523) leaves the magnetic push block (2562), and the magnetic push block (2562) loses the external force. Due to the magnetic block (2563) and the magnetic push block (256 2) The corresponding side is of the same polarity, which will generate a certain repulsive force, pushing the magnetic push block (2562) away, so that the arc-shaped gasket (2561) connected below the magnetic push block (2562) is reinserted under the slip ring (254), so that the slip ring (254) is lifted and reset again, and the steel sheet above the riveted top block (255) is squeezed out. At this time, the intermittent feeding device drives the steel belt to move to the discharge hole (26). Since the steel sheet is still inside the steel belt cutting position, it will be driven to move together, and the circular waste in the center of the annular steel sheet will fall into the discharge hole (26) for discharge; Step 5. When the intermittent feeding device pushes the annular steel sheet in the steel belt to the position on the sliding plate (275) in the overlapping mechanism (27), the annular steel sheet will sink. Since a riveted protrusion (2751) is arranged above the sliding plate (275), the riveted protrusion (2751) will be embedded in the depression at the bottom of the annular steel sheet. Before each intermittent feeding device drives the annular steel sheet to move, the third hydraulic cylinder (274) will drive the upper sliding plate (275) to drop a certain distance, so that the annular steel sheet has enough sinking space, so that each subsequent stacking of the annular steel sheets is in the cylindrical groove (273), avoiding stacking during stamping. The annular steel sheets are offset, and the second hydraulic cylinder (271) above drives the second pressure plate (272) to punch the stacked annular steel sheets, so that the protrusions and depressions on the upper and lower annular steel sheets are riveted to each other to complete the splicing. In this way, after each stacking of steel sheets, punching and riveting are performed. After punching, the second hydraulic cylinder (271) drives the second pressure plate (272) to rise, and the third hydraulic cylinder (274) drives the upper sliding plate (275) to fall. In addition, since the surface of the steel sheets is coated with adhesive in advance, the strength of the connection is greatly improved, so that the radial and axial load-bearing capacity of the steel sheet stamping stack is greatly improved. Step 6: When the stacked thickness of the annular steel sheets reaches the required requirement, after the second hydraulic cylinder (271) drives the second pressure plate (272) to complete the last stamping, the second hydraulic cylinder (271) lifts the second pressure plate (272) to increase the drive push rod (2766) to rise and contact the pressure rod (2767), and squeezes the piston rod (2765), so that the piston rod (2765) is squeezed from the air pipe (2764) through the air inlet (2763) and injected into the air cavity (2761). The injected gas squeezes the push plate (2762), and the stacked stamping is pushed through the push plate (2762). The stacked parts are pushed from the cylindrical groove (273) into the discharge port (276) and discharged through the inclined surface of the discharge port (276). The processing is completed. After the stamped stacked parts are discharged, the second hydraulic cylinder (271) moves to the position initially prepared for stamping. After the pressure rod (2767) loses the squeezing of the push rod (2766), the piston rod (2765) is reset under the action of the internal spring tension, and the air in the air cavity (2761) is extracted to reset the push plate (2762). The third hydraulic cylinder (274) also drives the sliding plate (275) to reset in preparation for subsequent stamping and stacking, thereby achieving the purpose of continuous and efficient processing.
