Description

Technical Field

[0001] The present application relates to the field of rotor processing technology, and in particular to a winding compression shaping device. Background Art

[0002] The rotor refers to a rotating body supported by bearings. It is mostly the main rotating component in power machinery and working machinery. There are wires wrapped around the rotor. When the rotor is used in a narrow space, it needs to be flattened.

[0003] In the related art, the flattening process of the rotor requires first tightening the clamps of the windings at the core body, and then flattening the rotor; it is usually performed on two sets of hydraulic molds, both sets of hydraulic molds include an upper mold base and a lower mold base, the bottom wall of the upper mold base is connected to the upper mold, the lower mold base is connected to the lower mold base, and the lower mold base has an installation groove; the upper mold bases of the two sets of hydraulic molds are both groove-shaped, and the groove of the upper mold base that tightens the clamps of the windings is smaller than the groove of the upper mold base that flattens the rotor; the operator first places the rotor in the lower mold base of the first set of molds, tightens the clamps of the windings at the rotor core, and then takes the rotor out of the lower mold base of the first set of molds and places it in the lower mold base of the second set of molds for flattening, thereby completing the compression and shaping of the rotor windings.

[0004] With respect to the above-mentioned related technologies, the processing of rotors is usually batch processing. When operators process multiple rotors, they need to transfer multiple rotors between two sets of molds multiple times, resulting in low work processing efficiency when flattening batches of rotors. Summary of the Invention

[0005] In order to improve the working efficiency of rotor flattening, the present application provides a winding compression and shaping device.

[0006] The present application provides a winding compression shaping device that adopts the following technical solution:

[0007] A winding compression and shaping device includes an upper die base and a lower die base, a guide column is provided between the upper die base and the lower die base, and the top wall of the upper die base is provided with a driving machine that drives the upper die base to move along the length direction of the guide column; the bottom wall of the upper die base is connected to the core upper die, and the top wall of the lower die base is connected to the core lower die for cooperating with the core upper die; the bottom wall of the upper die base is also connected to the winding upper die, and the top wall of the lower die base is also connected to the winding lower die that cooperates with the winding upper die; a first positioning groove is provided on the core lower die, and a second positioning groove is provided on the winding mounting seat.

[0008] By adopting the above technical solution, when flattening the rotor, the rotor is first placed in the first positioning groove of the lower mold of the core body. The driving motor is started to drive the upper mold base to move downward along the guide column, so that the upper mold of the core body is pressed downward, and the clamping claws of the windings on the core body are pressed tightly. After the core body is shaped, the upper mold base is reset upward, and the rotor that has been processed at the core body is placed in the second positioning groove of the lower mold of the windings; at the same time, a new unprocessed rotor is placed in the lower mold of the core body; the upper mold base is started downward again, and different parts of the two rotors can be pressed separately. When processing subsequent rotors, the above steps are repeated, and the processing of the two rotors in different steps can be completed in one downward stroke of the upper mold base, thereby improving the work efficiency of the rotor flattening process.

[0009] Preferably, there is a distance between the core lower mold and the winding lower mold and the lower mold base, and the height of the core lower mold is higher than the winding lower mold; a lifting plate is provided in the first positioning groove, and a discharge groove is provided on the inner side wall of the first positioning groove, a lifting rod is inserted into the discharge groove, and the lifting rod is rotatably connected to the lifting plate, and a driving member for driving the lifting rod to move upward is provided on the lower mold base; a stopper is also provided on the side wall of the lifting plate, and a clearance groove for inserting the stopper is also provided on the inner side wall of the first positioning groove;

[0010] A material guide plate is arranged between the core lower mold and the winding lower mold. The material guide plate is arranged at an angle, the upper end of the material guide plate is located above the makeshift groove, and the lower end of the material guide plate is located on one side of the second positioning groove; the upper mold base is provided with a makeshift opening for making way for the material guide plate.

[0011] By adopting the above technical solution, after the rotor is processed in the first positioning groove, the driving part can be started to drive the lifting rod and the support rod to move upward, driving the lifting plate to move upward, and the lifting plate supports the rotor to discharge the material from the first positioning groove; during the upward movement of the lifting plate, the stop block is driven to move upward synchronously, and after the stop block moves to contact with the upper end of the guide plate, the stop block stops moving. As the lifting rod moves further upward, the lifting plate will rotate and tilt. After the lifting plate tilts, the rotor will slide onto the guide plate under the action of gravity, and further slide into the second positioning groove on the guide plate, reducing the situation where the operator has to move the rotor from the first positioning groove to the second positioning groove.

[0012] Preferably, a discharge plate is provided in the second positioning groove, and a driving cylinder is provided on the lower die base, and the driving shaft of the driving cylinder passes through the winding lower die and is connected to the discharge plate; the driving cylinder can drive the discharge plate to move up to dock with the lower end of the guide plate.

[0013] By adopting this technical solution, the drive cylinder can drive the discharge plate upward to connect with the lower end of the guide plate. When the rotor slides down from the guide plate, it will first slide onto the discharge plate, thereby arranging the rotor in a horizontal position. The discharge plate then moves downward to drive the rotor into the second positioning groove for processing, improving the accuracy of the rotor's second positioning groove. At the same time, the discharge plate can eject the rotor from the second positioning groove, making it easier for the operator to remove the processed rotor.

[0014] Preferably, a plurality of mounting grooves are provided on the top wall of the discharge plate, rollers are rotatably connected in the mounting grooves, and the side walls of the rollers partially protrude from the mounting grooves.

[0015] By adopting the above technical solution, when the rotor moves to the discharge plate, it will contact the roller. The roller can convert the moving friction between the rotor and the discharge plate into rolling friction, reducing the resistance of the rotor sliding on the discharge plate, allowing the rotor to slide into place at one time, reducing the operator's adjustment of the rotor position.

[0016] Preferably, a mounting plate for connecting the roller is provided in the mounting groove, and a first spring is provided between the mounting plate and the bottom wall of the mounting groove; the first spring pushes the mounting plate to drive the roller to protrude from the mounting groove.

[0017] By adopting the above technical solution, when the winding mold presses down on the rotor, it will drive the roller to make the mounting plate compress the first spring, thereby inserting the roller into the mounting groove, making the discharge plate stick to the bottom wall of the second positioning groove, and reducing the pressure exerted by the roller on the bottom wall of the discharge plate.

[0018] Preferably, the top wall of the winding lower mold is provided with a baffle for shielding the rotor.

[0019] By adopting the above technical solution, after the rotor slides onto the discharge plate, the baffle can block the sliding of the rotor, thereby reducing the rotor from sliding excessively on the discharge plate and causing misalignment with the winding line lower mold.

[0020] Preferably, the baffle is rotatably connected to the top wall of the lower winding mold, and a second spring is provided between the baffle and the outer side wall of the lower winding mold, and the second spring pushes the baffle to rotate and be perpendicular to the top wall of the lower winding mold.

[0021] By adopting the above technical solution, when the discharge plate lifts the processed rotor out of the second positioning groove, the operator can remove the rotor from the winding lower mold. When the rotor collides with the baffle, the baffle can be pushed to rotate and make way. After the rotor is removed, the baffle can be reset under the elastic force of the second spring, reducing the interference of the baffle on the operator's removal of the rotor.

[0022] Preferably, a pull rope is further provided on the side wall of the baffle close to the second spring, and the end of the pull rope away from the baffle is connected to the outer side wall of the winding lower mold.

[0023] By adopting the above technical solution, the pull rope can limit the rotation of the baffle, so that the baffle stops rotating until it is perpendicular to the top wall of the winding mold, thereby reducing the situation where the second spring pushes the baffle to rotate excessively.

[0024] Preferably, a sliding groove is further provided on the inner side wall of the first positioning groove, a support rod is inserted into the sliding groove, and the support rod is connected to the driving machine; a counterweight block is embedded in the lifting plate close to the support rod, and the counterweight block drives the lifting plate to rotate and stick to the end wall of the support rod.

[0025] By adopting the above technical solution, after the rotor detaches from the lifting plate, the driving part drives the lifting rod to move downward to make the lifting plate move downward. After the lifting plate moves downward to drive the stop block to detach from the guide plate, the gravity of the counterweight block can drive the lifting plate to rotate until it is in contact with the support rod, thereby realizing the reset of the lifting plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The winding compression shaping equipment can realize the processing of two rotors in different steps in one downward stroke of the upper die seat, reducing the need for operators to transfer multiple rotors between two sets of dies multiple times when processing multiple rotors, thereby improving the work efficiency of rotor flattening processing.

[0028] 2. The rotational connection between the lifting plate and the lifting rod, as well as the cooperation between the stop block and the guide plate, reduce the situation where the operator moves the wheel from the first positioning groove to the second positioning groove.

[0029] 3. The setting of the counterweight block and the support rod can make the lifting plate automatically rotate and reset after the rotor is separated from the lifting plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] The embodiment of the present application discloses a winding compression shaping device. Figure 1 The winding compression shaping equipment includes an upper die base 1 and a lower die base 2. The lower die base 2 is fixed to the workbench by bolts. A guide column 21 is arranged between the upper die base 1 and the lower die base 2. The guide column 21 is set to four and fixedly connected to the lower die base 2. The guide column 21 passes through the upper die base 1, and the upper die base 1 can slide along the length direction of the guide column 21; a driving machine 11 is arranged above the upper die base 1. The driving machine 11 can be a hydraulic press, and the driving rod of the hydraulic press is connected to the upper die base 1.

[0036] Reference Figure 1 and Figure 2 The bottom wall of the upper mold base 1 is fixedly connected to the core upper mold 12 by bolts, and the top wall of the lower mold base 2 is fixedly connected to the core lower mold 3 by bolts, and the core lower mold 3 is provided with a first positioning groove 31; the bottom wall of the upper mold base 1 is also fixedly connected to the winding upper mold 13 by bolts, and the top wall of the lower mold base 2 is also fixedly connected to the winding lower mold 4 by bolts, and the winding lower mold 4 is provided with a second positioning groove 41; the core lower mold 3 and the winding lower mold 4 are both connected to the lower mold base 2 through a support frame, the height of the core lower mold 3 is higher than the winding lower mold 4, and the height of the core upper mold 12 on the upper mold base 1 is also higher than the height of the winding upper mold 13.

[0037] When flattening a rotor, the rotor is first placed in the first positioning groove 31 of the core lower mold 3. The drive motor 11 is started to drive the upper mold base 1 downward along the guide column 21, causing the core upper mold 12 to press down and tighten the clamping claws of the several windings on the core. After the core is shaped, the upper mold base 1 is moved upward and reset, and the rotor that has been processed at the core is placed in the second positioning groove 41 of the winding lower mold 4. At the same time, a new unprocessed rotor is placed in the core lower mold 3. The upper mold base 1 is started downward again, and different parts of the two rotors can be pressed separately. When the rotor is needed after processing, the above steps are repeated, and the two rotors can be processed in different steps in one downward stroke of the upper mold base 1, which improves the efficiency of the rotor flattening process.

[0038] Reference Figure 1 and Figure 2 A lifting plate 32 is provided in the first positioning groove 31, and the lifting plate 32 is adapted to the inner wall of the first positioning groove 31. The inner side walls on both sides of the first positioning groove 31 are provided with discharge grooves 311, and the two discharge grooves 311 are located in a direction perpendicular to the axis connecting the first positioning groove 31 and the second positioning groove 41; lifting rods 33 are inserted into the two discharge grooves 311, and the two sides of the lifting plate 32 are rotatably connected to the two lifting rods 33 respectively; a driving part 23 is provided on the lower mold base 2, and the driving part 23 is a cylinder. The lower ends of the two lifting rods 33 pass through the core lower mold 3 and are connected to the driving shaft of the driving part 23.

[0039] Reference Figure 1 and Figure 2 A clearance groove 312 is provided on the inner side wall of the first positioning groove 31 close to the winding lower mold 4, and a stopper 321 is fixedly connected to the side wall of the lifting plate 32 close to the clearance groove 312; a guide plate 22 is provided between the core lower mold 3 and the winding lower mold 4, and the guide plate 22 is fixed to the lower mold base 2 through a bracket. The guide plate 22 is tilted, and the upper end of the guide plate 22 is located above the clearance groove 312, and the lower end of the guide plate 22 is located above the second positioning groove 41; the upper mold base 1 is provided with a clearance opening for making way for the guide plate 22.

[0040] Reference Figure 1 and Figure 2 A sliding groove 313 is provided on the inner side wall of the first positioning groove 31 away from the winding lower mold 4, and a support rod 34 is inserted into the sliding groove 313. The lower end of the support rod 34 passes through the core lower mold 3 and is connected to the driving shaft of the driving member 23; a counterweight block 322 is embedded in the side wall of the lifting plate 32 close to the support rod 34, and the counterweight block 322 can drive the lifting plate 32 to rotate and stick to the end wall of the support rod 34.

[0041] After the rotor is processed in the first positioning groove 31, the driving part 23 can be started to drive the lifting rod 33 and the support rod 34 to move upward, driving the lifting plate 32 to move upward, and the lifting plate 32 supports the rotor to discharge the material from the first positioning groove 31; during the upward movement of the lifting plate 32, the stop block 321 is driven to move upward synchronously, and after the stop block 321 moves to contact the upper end of the guide plate 22, the stop block 321 stops moving. As the lifting rod 33 moves further upward, the lifting plate 32 will rotate and tilt. After the lifting plate 32 tilts, the rotor will slide onto the guide plate 22 under the action of gravity, and further slide into the second positioning groove 41 on the guide plate 22, reducing the situation where the operator moves the rotor from the first positioning groove 31 to the second positioning groove 41. After the rotor is detached from the lifting plate 32, the driving part 23 drives the lifting rod 33 to move downward, causing the lifting plate 32 to move downward. After the lifting plate 32 moves downward and drives the stop block 321 to detach from the guide plate 22, the gravity of the counterweight block 322 can drive the lifting plate 32 to rotate until it is in contact with the support rod 34, thereby realizing the reset of the lifting plate 32.

[0042] Reference Figure 1 A discharge plate 42 is provided in the second positioning groove 41 , and a driving cylinder 24 is provided below the winding lower mold 4 . The driving cylinder 24 is a pneumatic cylinder, and the driving shaft of the driving cylinder 24 passes through the winding lower mold 4 and is connected to the discharge plate 42 .

[0043] The driving cylinder 24 can drive the discharge plate 42 to move upward to connect with the lower end of the guide plate 22. When the rotor slides down from the guide plate 22, it will first slide onto the discharge plate 42, so that the rotor is in a horizontal position. The discharge plate 42 then moves downward to drive the rotor to be inserted into the second positioning groove 41 for processing, thereby improving the accuracy of the rotor in the second positioning groove 41.

[0044] Reference Figure 3 A plurality of mounting grooves 421 are provided on the top wall of the discharge plate 42, and a mounting plate 422 is provided in the mounting groove 421. A first spring 424 is provided between the mounting plate 422 and the bottom wall of the mounting groove 421, and a roller 423 is rotatably connected to the mounting plate 422. The first spring 424 pushes the mounting plate 422 to make part of the side wall of the roller 423 protrude from the mounting groove 421.

[0045] When the rotor moves to the discharge plate 42, it will contact the roller 423. The roller 423 can convert the active friction between the rotor and the discharge plate 42 into rolling friction, reducing the resistance of the rotor sliding on the discharge plate 42, allowing the rotor to slide into place at one time, reducing the operator's adjustment of the rotor position; when the winding upper mold 13 presses down on the rotor, it will drive the roller 423 to make the mounting plate 422 compress the first spring 424, so that the roller 423 is inserted into the mounting groove 421, reducing the pressure of the roller 423 on the bottom wall of the discharge plate 42.

[0046] Reference Figure 1 and Figure 3The top wall of the winding lower mold 4 is rotatably connected with a baffle 43, and the baffle 43 is located on the side of the winding lower mold 4 away from the core lower mold 3. A second spring 431 is provided between the baffle 43 and the outer wall of the winding lower mold 4, and one end of the second spring 431 is fixedly connected to the side wall of the baffle 43, and the other end of the second spring 431 is fixedly connected to the mounting platform on the outer wall of the winding lower mold 4; a pull rope 432 is also provided between the baffle 43 and the outer wall of the winding lower mold 4, and one end of the pull rope 432 is fixedly connected to the side wall of the baffle 43, and the other end of the pull rope 432 is fixedly connected to the mounting platform on the outer wall of the winding lower mold 4.

[0047] The second spring 431 pushes the baffle 43 to rotate, and the pull rope 432 limits the baffle 43's rotation, stopping it until it is perpendicular to the top wall of the winding lower mold 4. After the rotor slides onto the discharge plate 42, the baffle 43 blocks the rotor's movement, preventing it from sliding excessively on the discharge plate 42 and becoming misaligned with the winding lower mold 4. Furthermore, when the discharge plate 42 lifts the finished rotor from the second positioning slot 41, the operator can remove the rotor from the winding lower mold 4. If the rotor collides with the baffle 43, the baffle 43 is pushed to rotate out of the way. After the rotor is removed, the baffle 43 returns to its original position under the force of the second spring 431, minimizing interference from the baffle 43 with the operator's removal of the rotor.

[0048] The implementation principle of a winding compression shaping device in the embodiment of the present application is as follows:

[0049] When flattening the rotor, first place the rotor in the first positioning groove 31 of the core lower mold 3, start the drive motor 11 to drive the upper mold base 1 to move downward along the guide column 21, and press the core upper mold 12 downward to tighten the clamping claws of the windings on the core. After shaping the core, the upper mold base 1 is moved upward and reset, and the rotor that has been processed at the core is placed inside the second positioning groove 41 of the winding lower mold 4; at the same time, a new unprocessed rotor is placed in the core lower mold 3; start the upper mold base 1 downward again, and then the two rotors can be pressed at different parts respectively. When the rotor is needed after processing, repeat the above steps, and the two rotors can be processed in different steps in one downward stroke of the upper mold base 1; this reduces the need for operators to transfer multiple rotors between the two sets of molds when processing multiple rotors, thereby improving the work efficiency of the rotor flattening process.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
