Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, and in particular to a stamping forming device for motor housings. Background Technology

[0002] As a key component in the motor structure, the manufacturing precision of the motor housing plays a decisive role in the overall performance and durability of the motor. Currently, the motor housing is usually manufactured by stamping it out using a stamping die. The upper module of the stamping die moves downward and, with the cooperation of the lower module, stamps the metal plate. After the action of multiple stamping dies, the metal plate gradually forms the motor housing.

[0003] The existing stamping forming equipment adopts a multi-station continuous punch press to complete the one-time forming of the motor housing. After the coil is uncoiled and leveled, it is fed into multiple stations in sequence by a servo feeding system. The stamping is carried out continuously in the order of blanking, multiple stretching, bottom hole punching, side window punching, flanging, shaping, and cutting. The shape and hole positions of the housing are gradually formed station by station. The mold has a built-in floating guide and pressure mechanism to ensure that the housing wall is coaxial and the ends are flat. The mold cavity is equipped with micro-lubrication and vacuum recovery to achieve clean production. The overall layout is compact and the process is concentrated. There is no need for transfer. The motor housing is fully automated from coil input to finished product output, which is suitable for mass production and high-precision motor housing manufacturing.

[0004] However, most motor housing stamping lines currently adopt a rigid layout with one machine and one material frame. The feeding mechanism is fixedly installed on the feeding side of a single multi-station punch press. The material frame, sheet divider, centering table, and feeding arm all correspond one-to-one with the main machine. When a company needs to expand production and add a second stamping line, it can only purchase a complete feeding station. The original equipment cannot be easily modified to achieve dual-machine sharing, which leads to repeated investment in hardware. The material frame, sheet divider, and control system all need to be repurchased, occupying additional space and funds. Moreover, the operation is decentralized. The staff must move the motor housing patches back and forth between two independent feeding machines. The replenishment path is long, the labor intensity is high, and it is easy for the cycle to be misaligned when one side is short of material while the other side is still waiting.

[0005] Therefore, a motor housing stamping forming device is proposed to solve the above problems. Summary of the Invention

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0033] In practical use, it has been found that current motor housing stamping lines generally adopt a rigid layout of one machine and one material frame. The feeding mechanism is fixedly installed on the feeding side of a single multi-station punch press. The material frame, sheet divider, centering table, and feeding arm are all one-to-one with the main machine. When a company needs to expand production and add a second stamping line, it can only purchase a complete feeding station. The original equipment cannot be easily modified to achieve dual-machine sharing, which leads to repeated investment in hardware. The material frame, sheet divider, and control system all need to be purchased again, occupying additional space and funds. Moreover, the operation is decentralized. The staff must carry the motor housing patches back and forth between two independent feeding machines. The replenishment path is long, the labor intensity is high, and it is easy to have a misalignment of the cycle when one side is short of material and the other side is still waiting. In order to solve the above problems, the following structure was invented.

[0034] like Figures 1-12The motor housing stamping forming device shown includes a stamping machine 1 and a servo feeding mechanism 2 installed on the stamping machine 1. The servo feeding mechanism 2 is used to use a vacuum suction cup to send single iron sheets in the upper storage frame 6 into the first station in sequence, and to use a pneumatic gripper to take out the semi-finished products that have completed stretching, punching and other processes from the second, third and fourth stations in sequence and put them into the next empty station. It realizes the bidirectional action of feeding new sheets and moving old parts at the same time. It is a mature technology in the prior art and will not be described in detail here. A transverse mover 3 is fixedly connected to the ground next to the stamping machine 1. The transverse mover 3 is mainly composed of a hydraulic telescopic cylinder and a transverse moving end. Under the action of the hydraulic telescopic cylinder, it can pull the moving end to move, thereby driving the base 4, the lower storage frame 5 and the upper storage frame 6 to move. By changing the position of the two lower storage frames 5 and the upper storage frame 6 below the servo feeding mechanism 2, the frame can be changed quickly without stopping the machine.

[0035] The moving end of the transverse mover 3 is fixedly connected to a pair of bases 4. The top of the base 4 is fixedly connected to a lower storage frame 5. The lower storage frame 5 is provided with an upper storage frame 6. The upper storage frame 6 and the lower storage frame 5 are both provided with sliding grooves 7 through the outer walls. The upper storage frame 6 is fixedly connected to both outer walls. The lifting frame 8 is fixedly connected to both outer walls. The lifting block 9 is slidably connected to the inner side of the lifting frame 8. The side wall of the lifting block 9 is slidably connected to a U-shaped feeding plate 10 through the transverse. The lower storage frame 5 is fixedly connected to the front side with an L-shaped plate 11. The upper electric telescopic cylinder 12 is fixedly connected to the front side of the L-shaped plate 11. A guide mechanism for limiting the position of the feeding plate 10 is also provided. The lifting frame 8 is provided with a lifting mechanism for driving the lifting block 9 to move up and down. The lower storage frame 5 is provided with a rectangular groove 13 through the bottom front side. The lower plate 14 is slidably connected to the inner side of the rectangular groove 13. The top end of the lower plate 14 is provided with an upper circular groove 15.

[0036] An L-shaped cavity is provided through the interior of the base 4. A side bracket 16 is fixedly connected to the bottom of the lower plate 14 relative to the position inside the L-shaped cavity. A lower electric telescopic cylinder 17 is fixedly connected to the outer wall of the base 4. The output end of the lower electric telescopic cylinder 17 is fixedly connected to the side wall of the side bracket 16.

[0037] The lifting mechanism includes a drive motor 18, a commutator 19 fixedly connected to the bottom of the lifting frame 8, a lead screw 20 fixedly connected to the output end of the top of the commutator 19, the top end of the lead screw 20 being rotatably connected to the top of the inner end of the lifting frame 8, the drive motor 18 being fixedly connected to the outer wall of the commutator 19, and the output end of the drive motor 18 being fixedly connected to the output end of the side wall of the commutator 19. The commutator 19 is mainly composed of two bevel gears, which enable the horizontally arranged drive motor 18 to drive the vertically arranged lead screw 20 to rotate. The lead screw 20 is threadedly connected to the inner side wall of the lifting block 9.

[0038] The top of the lower storage frame 5 is provided with a pair of sliding grooves 21 that are connected to the sliding groove 7 through the groove. The sliding grooves 21 are located on the side away from the L-shaped plate 11. The top of the side wall of the sliding groove 7 on the lower storage frame 5 is provided with a side opening 38, which is located on the side of the sliding groove 7 away from the sliding grooves 21.

[0039] The guiding mechanism includes guide rods 22, which are provided in two pairs. U-shaped rods 23 are fixedly connected to the side walls of the feeding plate 10, and the guide rods 22 are fixedly connected to the side walls of the U-shaped rods 23. L-shaped support frames 24 are fixedly connected to both sides of the outer wall of the base 4. Fixed plates 25 are fixedly connected to the top of the support frames 24. A middle groove 26 is opened on the side of the fixed plate 25 near the upper storage frame 6, and the middle groove 26 is located below the upper storage frame 6. The side walls of the middle groove 26 are inclined. The side ends of the guide rods 22 are inserted into the inner side of the middle groove 26. Side blocks 27 are fixedly connected to the upper and lower sides of the middle groove 26. The distance between the side blocks 27 is adapted to the height of the U-shaped rods 23. The height of the middle groove 26 is adapted to the diameter of the guide rods 22. The side ends of the guide rods 22 are set as smooth arc surfaces. The output end of the upper electric telescopic cylinder 12 is fixedly connected to a side plate 32. The side wall of the upper storage frame 6 is longitudinally slidably connected to the side wall of the side plate 32.

[0040] A pair of guide springs 28 are fixedly connected between the inner side of the lifting block 9 and the inner side of the feeding plate 10. The feeding plate 10 is inserted into the inner side of the slide 7.

[0041] The lower storage frame 5 has L-shaped grooves 29 on both sides of its outer wall, and inclined grooves 30 are formed between the two ends of the L-shaped grooves 29. The bottom of the inclined grooves 30 has a recessed groove 31, and the connection between the groove 31 and the inclined groove 30 is inclined. The side wall of the lifting frame 8 has a round hole, and a round rod 33 is slidably connected to the inside of the round hole. The round rod 33 is inserted into the inside of the L-shaped groove 29. The side end of the round rod 33 is set as a smooth arc surface. A return spring 34 is fixedly connected between the inside of the round hole and the side wall of the round rod 33.

[0042] During the stamping process of the motor housing, the raw material for stamping the motor housing is first placed in the lower storage frame 5 and the upper storage frame 6 (since the lower storage frame 5 and the upper storage frame 6 are connected vertically, it can be put directly from the top of the upper storage frame 6). Before that, if a stamping machine 1 is to be fed, the drive motor 18 needs to be started to drive the lead screw 20 to rotate, which in turn drives the threaded lifting block 9 to slide upward in the lifting frame 8. At this time, the guide rod 22 is on the side wall of the fixed plate 25 and is squeezed by the fixed plate 25. Therefore, the feeding plate 10 is in the state of extending out of the slide groove 7, and the guide spring 28 is in the stretched state. At the same time, during the downward movement of the feeding plate 10, the guide rod 22 will be driven to move on the side wall of the fixed plate 25. When passing through the middle groove 26, it will pass over the side block 27. Since the gap between the side blocks 27 is smaller than the gap between the guide rods 22,

[0043] Therefore, the guide rod 22 will not fall into the middle groove 26, but will pass directly over the side block 27. Then, the feeding plate 10 moves to the bottom of the lower storage box 5, where the motor housing raw material can be placed. During the feeding process, the drive motor 18 can be controlled to start and drive the lead screw 20 to rotate, driving the lifting block 9 to move upward in the lifting box 8, and driving the feeding plate 10 to move the motor housing raw material upward. This works in conjunction with the servo feeding mechanism 2 to achieve intermittent feeding. When the motor housing raw material in one of the upper storage boxes 6 and the lower storage box 5 is used up, the transverse mover 3 can be controlled to start and move the other set of upper storage boxes 6 and lower storage boxes 5 to below the servo feeding mechanism 2, thus achieving alternating feeding. During the feeding process, the operator can replenish the empty upper storage boxes 6 and lower storage boxes 5.

[0044] When feeding material to both stamping presses 1, before unloading, first control the drive motor 18 to start, driving the lifting block 9 to the bottom position of the upper storage frame 6. At this time, the lifting block 9 is located between the side opening 38 and the sliding groove 21, and drives the guide rod 22 to move between the side blocks 27. Then, control the upper electric telescopic cylinder 12 to start and push the side plate 32 to move, while simultaneously moving the upper storage frame 6 and the lifting frame 8, so that the upper storage frame 6 moves towards the L-shaped plate 11. During this process, the lifting frame 8 will move... The round rod 33 moves at the lateral end of the L-shaped groove 29, and then moves to the corner of the L-shaped groove 29. During this process, the guide rod 22 moves out from the side block 27 and from the fixed plate 25, thereby relieving the pressure on the guide rod 22. Then, under the elastic force of the guide spring 28, the feeding plate 10 is pushed to reset, so that the feeding plate 10 slides into the side opening 38 and drives the U-shaped rod 23 and the guide rod 22 to move. Then, the upper electric telescopic cylinder 12 can be controlled to push the upper storage frame 6 back to align with the lower storage frame 5.

[0045] During this process, the guide rod 22 will be inserted into the middle groove 26, and the U-shaped rod 23 will be positioned between the side blocks 27. Simultaneously, the round rod 33 will slide and reset within the L-shaped groove 29. Then, the motor housing raw material can be placed from the top of the upper storage frame 6. At this time, the feeding plate 10 is located within the sliding groove 7, thus not obstructing the motor housing raw material from falling into the lower storage frame 5. After the material is unloaded, the upper electric telescopic cylinder 12 can be controlled to continue driving the side plate 32 to move, pushing the upper storage frame 6 away from the L-shaped plate 11. The guide rod 22 slides in the middle groove 26 and the round rod 33 slides at the lateral end of the L-shaped groove 29. At the same time, the upper storage frame 6 and the lower storage frame 5 are separated. During this process, the motor housing raw material in the upper storage frame 6 will move, and the feeding plate 10 will move in the sliding groove 21. Then, when half of the motor housing raw material in the upper storage frame 6 is about to be moved out of the lower storage frame 5, the guide rod 22 moves to the inclined surface of the middle groove 26. Under the pressure of the inclined surface, the U-shaped rod 23 will gradually move.

[0046] Simultaneously, the feeding plate 10 is inserted into the bottom of the motor housing raw material in the upper storage frame 6, and the guide spring 28 is stretched. Then, the guide rod 22 moves out of the middle groove 26 and moves to the side wall of the fixed plate 25. At the same time, the round rod 33 also moves to the bottom of the inclined groove 30 and is located in front of the groove 31, thereby relieving the pressure on the round rod 33. Then, the elastic force of the return spring 34 lowers the side end of the round rod 33 and pushes it into the groove 31. Then, the upper electric telescopic cylinder 12 can be controlled to start pulling back the side block 27, while simultaneously driving the upper storage frame 6 to move. Reset. At this time, since the round rod 33 is inserted into the groove 31, and there is a step between the groove 31 and the lateral end of the L-shaped groove 29, it is restricted. Therefore, the round rod 33 can only slide in the groove 31. Under the pressure of the inclined surface of the inclined groove 30, it will gradually squeeze the round rod 33 to slide the lifting frame 8 upward, thereby driving the upper storage frame 6 to slide upward on the side plate 32. At the same time, the guide rod 22 slides obliquely upward on the side wall of the fixed plate 25 according to the trajectory of the inclined groove 30, so it will not slide into the middle groove 26.

[0047] Then, the round rod 33 slides into the inclined surface of the groove 31 and compresses the return spring 34 until the upper storage frame 6 and the lower storage frame 5 are completely aligned, but a gap is left between them to avoid obstructing the reset of the feeding plate 10. At this time, the round rod 33 moves to the top of the inclined groove 30 (located next to the longitudinal end of the L-shaped groove 29 in the inclined groove 30), thereby separating the motor housing raw materials previously stored in the upper storage frame 6 and the lower storage frame 5 from the middle by using lateral force. The feeding plate 10 limits the motor housing raw materials inside the upper storage frame 6 below the upper storage frame 6. Then, during the feeding process, the feeding plate 10 can lift the motor housings in the upper storage frame 6 in a row, so that the top of the upper storage frame 6 is discharged, and at the same time, the bottom of the lower storage frame 5 is discharged, forming a two-way feeding. Without the need for an additional power source or lifting mechanism, two stamping machines 1 can be fed in parallel in the same material frame, taking into account the difference in cycle time, with no change in site occupation and low expansion and transformation costs. Then, during feeding, the drive motor 18 can be controlled. The machine is started, driving the feeding plate 10 to move intermittently upwards, realizing intermittent material discharge from the top of the upper storage frame 6. During this process, the lower electric telescopic cylinder 17 is started, driving the side support 16 and the lower plate 14 to move (when discharging, the lowest motor housing material will fall into the upper circular groove 15), thus pushing out the lowest motor housing material. At the same time, due to the restriction of the top of the lower plate 14, the other motor housing materials in the lower storage frame 5 will not fall. Then the lower plate 14 drives the motor housing material to move out of the lower storage frame 5, which can then control the servo feeding mechanism 2 on the other stamping machine 1 to start picking up the material (it should be noted that since the feeding position of the lower storage frame 5 is at the bottom, when installing the other stamping machine 1, only one upward driving claw needs to be added). Then the lower plate 14 is reset, and the motor housing material in the lower storage frame 5 falls into the upper circular groove 15 under its own gravity. This process is repeated to realize the automatic feeding of the two stamping machines 1. After the feeding is completed, the above operation is repeated to replenish the material.

[0048] In summary, through the design of the above structure, the upper storage frame 6 and the lower storage frame 5 are designed vertically. Under the operation of the guide mechanism and the lifting mechanism, not only can the material be pushed directly from the bottom to the top to automatically feed a single stamping machine 1, but the material can also be divided from the middle. The lower storage frame 5 discharges material from the bottom through the lower plate 14, and the upper storage frame 6 discharges material from the top through the feeding plate 10, thereby realizing the automatic feeding of material to the two motor housing stamping machines 1.

[0049] Based on the above embodiments, it was found during use that the above structure can only realize automatic feeding of two stamping machines 1, which is relatively limited. For production workshops with large spaces, it is necessary to consider adding another stamping machine 1. Therefore, it cannot meet the user's needs. In order to solve the above problems, the above structure has been further improved.

[0050] A lower circular groove 35 is provided at the other end of the top of the lower plate 14. A sealing plate 36 is installed inside the lower circular groove 35 by bolts. A pair of through grooves 37 are provided at the top of the rectangular groove 13 relative to the bolts on the sealing plate 36.

[0051] When automatic feeding of the three stamping presses 1 is required, the bolts on the sealing plate 36 can be removed, and then the sealing plate 36 can be removed for use. Thus, when the lower electric telescopic cylinder 17 drives the lower plate 14 to run, the upper circular groove 15 moves the motor housing raw material out of the lower storage frame 5, and the lower circular groove 35 moves into the lower storage frame 5. Under its own weight, the motor housing raw material in the lower storage frame 5 falls into the lower circular groove 35. Then, the lower electric telescopic cylinder 17 drives the lower plate 14 to move in the opposite direction, which can push out the motor housing raw material in the lower circular groove 35. This process is repeated to achieve automatic feeding of the three stamping presses 1. (It should be noted that when feeding the three stamping presses 1, since the discharge speed of the lower storage frame 5 is twice that of the upper storage frame 6, in order to ensure that the three stamping presses 1 are fed at the same time, during the replenishment process, it is only necessary to replenish to half of the upper storage frame 6.)

[0052] In summary, the above structural design enables double-sided material discharge from the bottom of the lower storage frame 5, thereby achieving automatic material feeding for the three stamping machines 1, further improving the flexibility of the device and meeting the diverse needs of users.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0054] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
