Description

Technical Field

[0001] This invention belongs to the field of multi-stage centrifugal pump manufacturing technology, specifically relating to a stamping forming equipment and method for automated processing of combined pump covers. Background Technology

[0002] The pump cover plays a crucial role in multistage centrifugal pumps, primarily in terms of its compressive strength and inlet water filtration function. Firstly, as an important component of the pump body, the pump cover must possess excellent compressive strength to withstand the high-pressure conditions generated during multistage centrifugal pump operation. Under high pressure, the pump cover needs to maintain structural integrity, preventing deformation or cracking, and ensuring the sealing performance and operational stability of the entire pump body. Secondly, the pump cover typically features inlet water filter holes or filtration devices. This design effectively intercepts larger impurities and particles in the water, preventing them from entering the pump body and causing wear or blockage of critical components such as the impeller and guide vanes. A well-designed inlet water filter hole not only ensures smooth water flow but also extends the pump's service life. Furthermore, the combination of the pump cover's compressive strength and filtration function allows multistage centrifugal pumps to adapt to various complex operating conditions, ensuring both high hydraulic performance and improved equipment reliability.

[0003] For large-scale multistage centrifugal pumps, our company has designed a combined pump cover, which adds an axial pressure-resistant member to the outside of the pump cover component and a radial pressure-resistant member to the inside of the pump cover component.

[0004] The existing automated stamping equipment for pump cover processing has shortcomings. First, it cannot meet the automated stamping and assembly requirements of the above-mentioned combined pump cover. Second, it cannot simultaneously perform stamping processing of filter holes and flange connection holes, as well as grinding processing of the filter hole edges, while stamping and assembling the above-mentioned combined pump cover.

[0005] In view of this, the inventors hope to optimize and improve the existing stamping equipment for automated processing of pump covers. Summary of the Invention

[0026] The present invention also provides a stamping forming method for automated processing of combined pump covers, which is based on the above-mentioned stamping forming equipment for automated processing of combined pump covers, and includes the following steps:

[0027] 1) The loading and unloading robot places the radial compression blank on the positioning tube seat of the rotating loading assembly and fixes the blank by suction cup; the grooving assembly performs milling operation on the outer side of the compression ring of the radial compression blank. After each grooving is formed, the radial compression blank is rotated by a rotary driver at a certain angle to perform the next milling operation; this is repeated until all grooving is completed.

[0028] 2) The loading and unloading robot places the pump cover blank on the outside of the radial pressure-resistant blank. The stamping assembly drives the stamping block to advance horizontally, which together with the slot of the radial pressure-resistant blank encloses the inner concave forming area. The inner concave part is stamped and formed on the outside of the cylinder of the pump cover blank.

This process is repeated until all inner concave parts are processed.

[0029] 3) The loading and unloading robot places the axial pressure-resistant blank on the outside of the pump cover blank, so that the pressure-resistant tube of the axial pressure-resistant blank is inserted into the corresponding concave outer area of ​​the pump cover blank; multiple punches of the first punching assembly are pushed horizontally, penetrating both the radial pressure-resistant blank and the pump cover blank, punching out the first filter hole and the second filter hole respectively; after punching is completed, the snap-fit ​​protrusion of the grinding drive assembly is embedded in the snap-fit ​​groove of the punch, and the drive motor drives the punch to rotate at high speed through worm gear-worm wheel transmission, using the grinding layer on its surface to grind and deburr the inner wall of the filter hole;

[0030] 4) The vertical punch of the second punching assembly moves down, simultaneously punching out the first flange hole of the radial pressure-resistant member, the second flange hole of the pump cover member, and the third flange hole of the axial pressure-resistant member;

[0031] 5) The suction cup of the rotating loading component is released from adsorption, and the loading and unloading robot takes out the processed combined pump cover.

[0032] The beneficial effects of this invention are:

[0033] 1. Meets the requirements for automated stamping and assembly of modular pump covers: It can automatically stamp and assemble modular pump covers composed of radial pressure-resistant components, pump cover components, and axial pressure-resistant components, solving the problem that existing equipment cannot meet this requirement.

[0034] 2. Multifunctional integrated processing: While stamping and assembling the combined pump cover, the filter holes and flange connection holes can be stamped and the edges of the filter holes can be ground, which improves production efficiency, reduces equipment investment and processing steps, and lowers production costs.

[0035] 3.

Detailed Implementation

[0063] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0064] like Figure 1 As shown, this embodiment provides a combined pump cover automated processing stamping forming equipment, including a rotating material loading assembly 1, a grooving assembly 2, a stamping assembly 3, a first punching assembly 4, a grinding drive assembly 5, and a second punching assembly 6. The rotating material loading assembly 1 is located below the stamping forming station and is used to adsorb and lock the radial pressure-resistant blank 81a. The grooving assembly 2 is located on the left side of the stamping forming station and is used to perform a milling operation on the radial pressure-resistant blank 81a to form a groove 813. The stamping assembly 3 is located on the rear side of the stamping forming station and is used to perform a stamping operation on the pump cover blank 82a sleeved on the outside of the radial pressure-resistant blank 81a to form an inner concave portion 823. The first punching assembly 4 is located at the stamping forming station. On the left side of the stamping station, the radial pressure-resistant blank 81a and the pump cover blank 82a are punched simultaneously to form the first filter hole 814 and the second filter hole 824, respectively. The grinding drive assembly 5 is arranged opposite to the first punching assembly 4 and is used to drive the punch rod of the first punching assembly 4 to rotate, and use the punch rod to grind the inner walls of the first filter hole 814 and the second filter hole 824. The second punching assembly 6 is arranged above the stamping station and is used to punch the radial pressure-resistant blank 81a, the pump cover blank 82a, and the axial pressure-resistant blank 83a sleeved on the outside of the pump cover blank 82a, respectively to form the first flange hole 815, the second flange hole 825, and the third flange hole 834.

[0065] like Figures 3-8 As shown, the combined pump cover 8 is composed of radial pressure-resistant member 81, pump cover member 82, and axial pressure-resistant member 83 from the inside out.

[0066] The radial pressure resisting blank 81a consists of a first flange 811 and a pressure resisting ring 812 located at the edge of its inner hole. The radial pressure resisting component 81 has multiple slots 813 and first filter holes 814 offset from the slots 813 around the circumference of the pressure resisting ring 812. The radial pressure resisting component 81 has multiple first flange holes 815 around the circumference of the first flange 811. The radial pressure resisting component 81 can be made of high-strength alloy steel, such as 42CrMo alloy steel. This steel has high strength and toughness, can withstand large radial pressure, meets the radial pressure resistance requirements of multi-stage centrifugal pumps, and has good machinability, making it easy to perform grooving, punching and other processing operations.

[0067] The pump cover blank 82a consists of a second flange 821 and a cylindrical tube 822 located at the edge of its inner hole. The pump cover component 82 has multiple recesses 823 circumferentially around the cylindrical tube 822, and second filter holes 824 offset from the recesses 823. The pump cover component 82 has multiple second flange holes 825 circumferentially around the second flange 821. The pump cover component 82 is made of stainless steel, which has good corrosion resistance, preventing corrosion when the pump cover comes into contact with water or other media, thus ensuring the service life of the pump cover. Furthermore, the smooth surface of the stainless steel facilitates smooth water flow, reduces water flow resistance, and improves the hydraulic performance of the pump.

[0068] The axial compression-resistant blank 83a consists of a third flange 831, a compression-resistant tube column 832, and a protective cover plate 833. A ring of compression-resistant tube columns 832 is connected between the inner edge of the third flange 831 and the protective cover plate 833. The axial compression-resistant component 83 has multiple third flange holes 834 circumferentially opened on the third flange 831. The axial compression-resistant component 83 is made of Fe10W alloy, which can significantly resist high-pressure deformation and extend the service life of the component.

[0069] The combined pump cover 8 enables the pump cover to withstand the high-pressure conditions generated during the operation of multi-stage centrifugal pumps. It maintains structural integrity under high pressure, preventing deformation or cracking, ensuring the sealing performance and operational stability of the entire pump body, adapting to various complex operating conditions, and improving equipment reliability. It is equipped with a combined inlet filter hole, which effectively intercepts larger impurities and particles in the water, preventing them from entering the pump body and causing wear or blockage of critical components such as the impeller and guide vanes.

An upper pressure ring 106, which is slidably restricted within the lower pressure ring 105, is installed on the lower side of the turntable 103 near its edge. The positioning tube seat 104 has several rows of horizontal clearance holes 107 circumferentially arranged. The turntable 103 has a through hole inside the positioning tube seat 104, and several vertical clearance punches 108 are formed on the outer periphery of the turntable 103 around the positioning tube seat 104. Several suction cups 109 are embedded in the area between the positioning tube seat 104 and the vertical clearance punches 108 on the turntable 103. The stamping waste suction pump 110 has two suction pipes, one of which passes through the lower pressure ring 105, and the other suction pipe passes through the frame base plate 101 and communicates with the inner cavity of the positioning tube seat 104.

[0071] The design principle of the rotating material loading assembly 1 is as follows:

[0072] Frame base plate 101: Serves as the supporting foundation for the entire assembly and is used to install other components.

[0073] Rotary drive 102: Its moving ring supports the turntable 103. By driving the turntable 103 to rotate, it drives the radial pressure-resistant blank 81a on the positioning tube seat 104 to rotate, so as to realize processing operations at different angles.

[0074] Turntable 103: A positioning tube seat 104 is installed on the upper side for placing the radial pressure-resistant blank 81a; an upper pressure ring 106 is installed near the edge on the lower side, which slides and is restricted in the lower pressure ring 105, serving a positioning and stabilizing function; the positioning tube seat 104 has a row of horizontal clearance punches 107 circumferentially, and the turntable 103 has a through hole inside the positioning tube seat 104, and several vertical clearance punches 108 are opened on the periphery to facilitate the discharge of waste materials and the passage of parts during punching and other operations; several suction cups 109 are embedded in the area between the positioning tube seat 104 and the vertical clearance punches 108 for adsorbing and locking the radial pressure-resistant blank 81a.

[0075] The lower pressure ring 105 and the upper pressure ring 106 cooperate with each other to position and stabilize the turntable 103, ensuring the accuracy of the turntable 103 during rotation.

[0076] Waste suction pump 110 for punching: It is equipped with two suction pipes, one of which passes through the lower pressure ring 105 and the other passes through the frame base plate 101 and communicates with the inner cavity of the positioning pipe seat 104. It is used to suction waste generated by punching and other operations to keep the working area clean.

The first horizontal guide rod 203, which penetrates the left side plate 201 of the frame, is fixed to the back side of the slide rail of the vertical linear guide rail pair 204. The milling device 205 is installed on the outside of the slider of the vertical linear guide rail pair 204.

[0078] The design principle of slotted component 2 is as follows:

[0079] Left side panel 201 of the frame: serves as a supporting structure for mounting other components.

[0080] First horizontal push rod 202: Supports the slide rail of the vertical linear guide pair 204 and pushes the slide rail to move horizontally.

[0082] Vertical linear guide rail pair 204: A milling device 205 is installed on the outside of its slider. The horizontal movement of the guide rail drives the slider and the milling device 205 to move horizontally. At the same time, the slider can move vertically on the guide rail, so as to adjust the position of the milling device 205 in the horizontal and vertical directions, so as to perform milling operation on the outside of the pressure ring 812 of the radial pressure blank 81a.

[0083] Milling device 205: Driven by vertical linear guide pair 204, it mills grooves on radial compression blank 81a. After each groove 813 is formed, rotary drive 102 drives radial compression blank 81a to rotate a certain angle to perform the next milling operation until all grooves 813 are processed.

[0084] like Figure 13 As shown, the stamping assembly 3 includes a frame rear side plate 301, a second horizontal push rod 302, a second horizontal guide rod 303, a movable carrier plate 304, and a stamping block 305.

The stamping block 305 can, together with the slot 813 of the radial pressure resisting member 81, form an inner concave forming area for forming the inner concave part 823.

[0085] The design principle of stamping component 3 is as follows:

[0086] Rear panel 301 of the frame: serves as a supporting structure for mounting other components.

[0087] Second horizontal push rod 302: Supports movable carrier plate 304 and pushes movable carrier plate 304 to move horizontally.

[0088] The second horizontal guide rod 303 passes through the rear side plate 301 of the frame and is fixed to the inside of the movable carrier plate 304. It plays a guiding role and ensures the stability of the horizontal movement of the movable carrier plate 304.

[0089] Movable carrier plate 304: A stamping block 305 is installed on the outside, which is driven to move horizontally by the second horizontal push rod 302.

[0090] Stamping block 305: Together with the slot 813 of the radial pressure-resistant member 81, it forms an inner concave forming area for forming the inner concave part 823. The inner concave part 823 is stamped on the outside of the tube 822 of the pump cover blank 82a. After each inner concave part 823 is formed, the rotary driver 102 drives the pump cover blank 82a to rotate a certain angle to perform the next stamping operation until all inner concave parts 823 are processed.

[0106] The design principle of the second punching component 6 is as follows:

[0107] Frame top plate 601: As a supporting structure, its inner wall is fixed with the slide rail of the horizontal linear guide pair 602, and it has loading and unloading windows 605 to facilitate loading and unloading operations.

[0108] Horizontal linear guide pair 602: A vertical push rod 603 is installed on the outside of its slider. The slider can move horizontally on the slide rail, driving the vertical push rod 603 to move horizontally.

When the vertical punch moves down, it simultaneously punches out the first flange hole 815 of the radial pressure resisting member 81, the second flange hole 825 of the pump cover member 82, and the third flange hole 834 of the axial pressure resisting member 83.

[0111] like Figure 2 As shown, it also includes a controller 7 and a loading / unloading robot.

[0112] This embodiment also provides a stamping method for automated processing of a combined pump cover, including the following steps:

[0113] 1) The loading and unloading robot places the radial compression-resistant blank 81a on the positioning tube seat 104 of the rotating loading assembly 1, and fixes the blank by suction cup 109; the grooving assembly 2 performs a milling operation on the outer side of the compression ring 812 of the radial compression-resistant blank 81a. After each grooving 813 is formed, the rotary driver 102 drives the radial compression-resistant blank (the rotary driver 102 drives the turntable 103 to rotate, and the turntable 103 is attracted and locked to the radial compression-resistant blank 81a by suction cup 109) to rotate a certain angle, and the next milling operation can be performed; repeat until all grooving 813 are processed.

[0114] 2) The loading and unloading robot places the pump cover blank 82a on the outside of the radial pressure-resistant blank 81a. The stamping assembly 3 drives the stamping block 305 to advance horizontally, which together with the slot 813 of the radial pressure-resistant blank 81a encloses the concave forming area. The concave part 823 is stamped on the outside of the tube 822 of the pump cover blank 82a. After each concave part 823 is formed, the pump cover blank 82a is driven by the rotary driver 102 to rotate by a certain angle (at this time, the radial pressure-resistant blank 81a and the pump cover blank 82a are mutually limited in the circumference and can rotate synchronously) so that the next stamping operation can be performed. This process is repeated until all the concave parts 823 are processed.

[0115] 3) The loading and unloading robot places the axial pressure-resistant blank 83a onto the outside of the pump cover blank 82a, so that the pressure-resistant tube 832 of the axial pressure-resistant blank 83a is engaged in the outer area of ​​the corresponding concave portion 823 of the pump cover blank 82a; multiple punching rods of the first punching assembly 4 are horizontally advanced, simultaneously penetrating the radial pressure-resistant blank 81a and the pump cover blank 82a, punching out the first filter hole 814 and the second filter hole 824 respectively; by pre-engaging the axial pressure-resistant blank 83a on the outside of the pump cover blank 82a, deformation of the concave portion of the second filter hole 824 during the punching process can be avoided. After punching is completed, the engaging protrusion 508 of the grinding drive assembly 5 is embedded into the engaging groove 407 of the punching rod, and the drive motor 502 drives the punching rod to rotate at high speed through worm gear transmission, using the grinding layer 408 on its surface to grind and deburr the inner wall of the filter hole;

[0116] 4) The vertical punch of the second punching assembly 6 moves down and simultaneously punches out the first flange hole 815 of the radial pressure resisting member 81, the second flange hole 825 of the pump cover member 82 and the third flange hole 834 of the axial pressure resisting member 83.

[0117] 5) The suction cup of the rotating loading component 1 is released from adsorption, and the loading and unloading robot takes out the processed combined pump cover 8.
