Description

Technical Field

[0001] This application relates to the field of feeding devices, and in particular to a device for manufacturing motor cores from multiple types of steel sheets. Background Technology

[0002] Currently, most motor cores on the market are made of steel sheets, which are mostly rolled into discs. During the feeding process, the steel sheets need to be unrolled and fed at the same time.

[0003] For example, Chinese utility model patent CN206298190U discloses a steel sheet feeding device, including a frame and a material tray rotating device, a guide plate and a paper tape collecting device disposed on the frame. The material tray rotating device is configured to carry the steel sheet tray and rotate the steel sheet tray to release the steel sheet when there is a shortage of material. The guide plate includes a raw material inlet end and a raw material outlet end. The released steel sheet enters the guide plate from the raw material inlet end and exits from the raw material outlet end. The paper tape collecting device is configured to rotate and collect the paper tape separated from the steel sheet.

[0004] When using the above-mentioned steel sheet feeding device, the steel sheet unwound from the tray has a certain curvature during the feeding process. After being processed along the guide plate from the raw material output end, it affects the flatness of the workpiece and needs to be improved. Summary of the Invention

[0005] In order to make the processed workpiece flat, this application provides a multi-type steel sheet manufacturing equipment for motor cores.

[0006] The technical solution provided in this application for a multi-model steel sheet manufacturing equipment for motor cores is as follows:

[0007] A multi-type steel sheet manufacturing equipment for motor cores includes a steel sheet unwinding device, a feeding rack, and a correction device mounted on the feeding rack. The steel sheet unwinding device is used to wind up the steel sheets. A plurality of upper pressure rollers and a plurality of lower pressure rollers are rotatably connected to the feeding rack. The upper pressure rollers and the lower pressure rollers are arranged correspondingly. A gap is provided between the upper pressure rollers and the lower pressure rollers for the steel sheets to pass through.

[0008] By adopting the above technical solution, in actual use, after the steel sheet unwinding equipment passes through several gaps, the upper and lower pressure rollers press the steel sheet to eliminate the curvature of the part of the steel sheet passing through the gaps, so that the processed parts are flat, which is conducive to improving the quality of subsequent processed parts.

[0009] Preferably, the device further includes a detection frame and an induction controller mounted on the detection frame. The detection frame is located between the steel sheet unwinding device and the straightening device. The steel sheet is fed through the detection frame, the straightening device, and the correction device in sequence. The induction controller is used to detect the steel sheet on the detection frame and control the operation of the steel sheet unwinding device. When the induction controller detects that there is no steel sheet on the detection frame, the induction controller controls the steel sheet unwinding device to stop operating.

[0010] By adopting the above technical solution, in actual use, the steel sheet wound on the steel sheet unwinding equipment passes through the detection frame, gap one, and correction device before entering the processing equipment. When the tail end of the steel sheet passes the detection frame, the sensor controller detects that no steel sheet has passed through the detection frame and controls the steel sheet unwinding equipment to stop operating. When the operator winds a new steel sheet onto the steel sheet unwinding equipment and passes it through the detection frame, the sensor controller detects that a steel sheet has passed through the detection frame again and controls the steel sheet unwinding equipment to start operating and unwind the steel sheet. By setting up a detection frame and sensor controller to monitor the steel sheet, it is beneficial to reduce energy waste caused by equipment idling.

[0011] Preferably, the feeding rack is provided with a discharge port and a transition frame, the transition frame is used to support the steel sheet, the transition frame extends to provide a channel through which the steel sheet passes, the channel bends toward the discharge port, and the degree of bending of the channel is less than the critical value of elastic deformation of the steel sheet.

[0012] By adopting the above technical solution, and by setting the channel to be curved, after all the steel sheets on the steel sheet unwinding equipment are unwound, the amount of steel sheets remaining in the channel is increased, allowing sufficient time for feeding the steel sheets on the steel sheet unwinding equipment. This allows for simultaneous processing and feeding of the steel sheets, which helps to improve processing efficiency.

[0013] Preferably, the induction controller is slidably connected to the detection frame, and the sliding direction of the induction controller is perpendicular to the distribution direction of the steel sheet unwinding device and the detection frame.

[0014] By adopting the above technical solution, in the actual material feeding process, when the steel sheet type is different and the length of the steel sheet in the vertical steel sheet unwinding equipment and detection frame distribution direction is different, by adjusting the position of the induction controller, the projection of the induction controller in the vertical direction is consistently located on the steel sheet, which can be applied to the detection of the allowance of different types of steel.

[0015] Preferably, the steel sheet unwinding device includes a frame, a positioning shaft rotatably connected to the frame, and a sliding seat slidably connected to the frame. The positioning shaft is used to position the steel sheet tray, and the sliding seat is used to place a replacement steel sheet tray. The sliding seat slides closer to or further away from the positioning shaft. The positioning shaft is provided with a positioning component, which is used to position the steel sheet tray.

[0016] By adopting the above technical solution, in actual use, after the steel sheets on the steel sheet tray on the positioning shaft are unwound, the steel sheet tray is removed from the positioning shaft, and the sliding seat moves towards the positioning shaft, allowing the positioning shaft to pass through and position the steel sheet tray on the sliding seat. The rotation of the positioning shaft drives the steel sheet tray to unwind the steel sheets. Replacing the steel sheet tray support improves replacement efficiency.

[0017] Preferably, a plurality of abutting rods are rotatably connected to the sliding seat, and the abutting rods are used to abut against the opposite sides of the replacement tray to position the replacement tray.

[0018] By adopting the above technical solution, after the replacement tray has finished winding the steel sheet, the clamping rod rotates towards the replacement tray to clamp the steel sheet wound on the replacement tray, which helps to improve the stability of the replacement tray on the sliding seat.

[0019] Preferably, the positioning assembly includes a limiting rod rotatably connected to the positioning shaft, a positioning pin slidably connected to the positioning shaft, and a driving structure disposed on the positioning shaft. The limiting rod is used to rotatably abut against the side of the steel sheet tray near the sliding seat, the positioning pin slides into or out of the steel sheet tray, and the driving structure drives the limiting rod and the positioning pin to move.

[0020] By adopting the above technical solution, after the steel sheet tray is installed on the positioning shaft, the limiting rod rotates and abuts against the steel sheet tray. The limiting rod and the frame abut against opposite sides of the steel sheet tray, making it less likely for the steel sheet tray to move along the length of the positioning shaft during rotation and unwinding, thus improving the positioning stability of the steel sheet tray. The positioning pin, which engages the steel sheet tray, further facilitates its positioning.

[0021] Preferably, the driving structure includes a driving block slidably connected to the positioning shaft, a rack disposed on the driving block, and a driving gear coaxially disposed on the limiting rod. The positioning pin is provided with a guide surface one, which is inclined towards the driving block and away from the axis of the positioning shaft. The driving block slides into or out of the moving path of the positioning pin, and the driving block abuts against the guide surface one. The positioning shaft is provided with an elastic element one and an elastic element two. The elastic element one pulls the positioning pin so that the positioning pin tends to move into the positioning shaft. The elastic element two abuts against the driving block so that the driving block tends to move closer to the positioning pin. The elastic force of the elastic element two is greater than the elastic force of the elastic element one.

[0022] By adopting the above technical solution, when positioning the positioning shaft and the steel sheet tray, the elastic element two abuts against the drive block, causing the drive block to abut against the guide surface one. This allows the positioning pin to move along the inclined direction of the guide surface, extending out of the positioning shaft and engaging with the steel sheet tray for positioning. Simultaneously, as the drive block moves closer to the positioning pin, the rack moves, driving the drive gear to move, causing the limiting rod to rotate towards the steel sheet tray and abut against it. When it is necessary to replace the steel sheet tray, the drive block is moved away from the positioning pin, disengaging from the guide surface. Under the action of the elastic element one, the positioning pin moves and extends into the positioning shaft. The rack and drive gear mesh, causing the limiting rod to rotate away from the steel sheet tray, causing the projection of the limiting rod on the axial direction of the steel sheet tray to disengage from the tray, allowing the steel sheet tray to be removed from the positioning shaft. This facilitates the removal of the steel sheet tray.

[0023] Preferably, a pressure rod is slidably connected to the frame, the pressure rod is located above the steel sheet tray, and an elastic element three is provided on the frame. The elastic element three abuts against the pressure rod, so that the pressure rod tends to move closer to the positioning shaft.

[0024] By adopting the above technical solution, as the material is fed, the number of steel sheets wound on the steel sheet tray gradually decreases, and the pressure bar keeps pressing the steel sheets tightly under the action of the elastic element three, so that the steel sheets wound on the steel sheet tray are not easy to unravel.

[0025] Preferably, the pressure rod is provided with an abutment block, the driving block is annular, one end of the driving block away from the positioning pin extends into the frame, the driving block is provided with a second guide surface, the second guide surface is located on the moving path of the abutment block, the second guide surface is inclined in the direction close to the positioning axis towards the positioning pin, and the second guide surface is used to abut the abutment block.

[0026] By adopting the above technical solution, during actual processing, as the number of steel sheets in the steel sheet tray gradually decreases, the pressure block gradually moves closer to the positioning shaft. The pressure block drives the abutment block to move closer to the drive block, abutting the guide surface two. The pressure rod continues to move closer to the positioning shaft until it abuts the steel sheet tray. At this point, the drive block moves away from the positioning pin, disengaging from the positioning pin, contacting the steel sheet tray, and positioning itself. When all the steel sheets in the steel sheet tray are unwound, the positioning shaft and the steel sheet tray automatically release their positioning, which helps improve the assembly and disassembly efficiency of the steel sheet tray.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By pressing the steel sheet with the upper and lower pressure rollers, the curvature of the steel sheet passing through the gap is eliminated, making the processed part flat, which is beneficial to improving the quality of the parts processed in subsequent processes;

[0029] 2. Monitoring the steel sheets by setting up a detection frame and an induction controller helps reduce energy waste caused by equipment idling;

[0030] 3. By adjusting the position of the induction controller, the vertical projection of the induction controller is consistently located on the steel sheet, which can be applied to the detection of the allowance of different types of steel. Attached Figure Description

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] This application discloses an equipment for manufacturing motor cores using various types of steel sheets. (Refer to...) Figure 1 and Figure 2 A multi-model steel sheet manufacturing equipment for motor cores includes a steel sheet unwinding device 1, a detection frame 2, an induction controller 3, a feeding frame 4, and a correction device 5. The steel sheet unwinding device 1, the detection frame 2, and the feeding frame 4 are arranged in a straight line. The detection frame 2 is located between the steel sheet unwinding device 1 and the feeding frame 4. The induction controller 3 includes a controller 31 and a sensor 32. The controller 31 is fixed on the steel sheet unwinding device 1 to control its operation. The sensor 32 is slidably connected to the detection frame 2. The sliding direction of the sensor 32 is horizontal and perpendicular to the distribution direction of the steel sheet unwinding device 1 and the detection frame 2. The correction device 5 is fixed on the detection frame 2. The steel sheet passing through the steel sheet unwinding device 1 passes through the detection frame 2 and the correction device 5 in sequence. The steel sheet is located below the sensor 32. The sensor 32 is used to detect whether there is a steel sheet passing through the detection frame 2 and sends a signal. The controller 31 receives the signal sent by the sensor 32 and controls the operation of the steel sheet unwinding device 1. In this embodiment, the sensor 32 is driven to move by a lead screw structure.

[0039] During the feeding process, the steel sheet passes under the sensor 32. When the sensor 32 detects that a steel sheet has passed the detection frame 2, the sensor 32 activates an operation signal. The controller 31 receives the operation signal sent by the sensor 32 and controls the steel sheet unwinding device 1 to operate. When the tail end of the steel sheet passes under the sensor 32, there is no steel sheet on the steel sheet unwinding device 1. After the sensor 32 detects that no steel sheet has passed the detection frame 2, the sensor 32 sends a stop signal. The controller 31 receives the stop signal sent by the sensor 32 and controls the steel sheet unwinding device 1 to stop operating and load a new steel sheet. In this embodiment, the sensor 32 is a laser sensor 32.

[0040] Reference Figure 1 and Figure 3 The feeding rack 4 is rotatably connected to several upper pressure rollers 41 and several lower pressure rollers 42. The upper pressure rollers 41 are evenly distributed at equal intervals along a straight line on the feeding rack 4. The upper pressure rollers 41 and lower pressure rollers 42 are both located on the side of the correction device 5 near the detection rack 2. The positions and numbers of the upper pressure rollers 41 and lower pressure rollers 42 correspond one-to-one. The upper pressure roller 41 is located below the corresponding lower pressure roller 42. The rotation axis of the upper pressure roller 41 is parallel to the rotation axis of the lower pressure roller 42. The rotation axis of the upper pressure roller 41 is perpendicular to the distribution direction of the detection rack 2 and the feeding rack 4. The rotation axis of the upper pressure roller 41 is horizontal. A gap 43 is formed between the upper pressure roller 41 and the corresponding lower pressure roller 42. Several gaps 43 are located on the same straight line. The gaps 43 allow steel sheets to pass through. The upper pressure rollers 41 and lower pressure rollers 42 press against the steel sheets passing through the gaps 43 to flatten the steel sheets.

[0041] Reference Figure 1 and Figure 3 A transition frame 44 is fixed on the feeding rack 4. The transition frame 44 includes two arc-shaped plates 441. The vertical projections of the two arc-shaped plates 441 are located on the feeding rack 4. The arc-shaped plates 441 are located on the side of the correction device 5 away from the upper pressure roller 41, and the arc center of the arc-shaped plates 441 is located on the side closer to the correction device 5. The two arc-shaped plates 441 are spaced apart and spliced ​​together to form a channel 442. The channel 442 is arc-shaped and allows the steel sheet to pass through. The degree of curvature of the channel 442 is less than the elastic deformation critical value of the steel sheet. In this embodiment, the elastic deformation critical value of the steel sheet refers to the maximum degree of curvature to which the steel sheet can return to flatness after bending.

[0042] Reference Figure 3 The feeding rack 4 is fixed with an upper pouring plate 45 and a lower pouring plate 46. The upper guide plate and the lower pouring plate 46 are spliced ​​together to form a discharge port 47. The discharge port 47 is located above the correction device 5 and the arc plate 441. The arc plate 441 bends towards the discharge port 47 so that the steel plate passes through the channel 442 and is fed from the discharge port 47.

[0043] In actual use, by bending the channel 442, the amount of steel sheet in the channel 442 is increased, so that the feeding can continue even when the steel sheet unwinding device 1 stops operating.

[0044] Reference Figure 1 and Figure 4 The steel sheet uncoiling device 1 includes a frame 11, a positioning shaft 12, a sliding seat 13, a steel sheet tray 14, and a replacement tray 15. The positioning shaft 12 is rotatably connected to the frame 11. The projection of the positioning shaft 12, parallel to the distribution direction of the inspection frame 2 and the loading frame 4, is located on the inspection frame 2. The rotation axis of the positioning shaft 12 is horizontal and perpendicular to the distribution direction of the inspection frame 2 and the loading frame 4. The steel sheet tray 14 passes through the positioning shaft 12, and a positioning component 6 is provided on the positioning shaft 12. The steel sheet tray 14 is fixed to the positioning shaft 12 through the positioning component 6. A drive motor 111 is fixed on the frame 11, and the drive motor 111 drives the positioning shaft 12 to rotate. A controller 31 is fixed on the frame 11 and is connected to the drive motor 111 through wires. The controller 31 controls the operation of the drive motor 111, thereby controlling the operation of the positioning shaft 12.

[0045] Reference Figure 4 The sliding seat 13 is slidably connected to the frame 11. The sliding direction of the sliding seat 13 is parallel to the rotation axis of the positioning shaft 12. The sliding seat 13 slides closer to or away from the positioning shaft 12. The sliding seat 13 is provided with a mounting groove 131. The mounting groove 131 passes through the sliding seat 13 in a direction parallel to the sliding direction of the sliding seat 13. The mounting groove 131 is gradually tapered downwards. The mounting groove 131 is used for the replacement tray 15 to be inserted and positioned.

[0046] Reference Figure 4 The steel sheet tray 14 and the replacement tray 15 have the same structure and purpose, both used for winding steel sheets. When the replacement tray 15 is inserted into the mounting groove 131, the mounting groove 131 presses against the steel sheet wound on the replacement tray 15 to fix the replacement tray 15. A clamping rod 132 is rotatably connected to the sliding seat 13. The clamping rod 132 is located on opposite sides of the mounting groove 131. The distribution direction of the clamping rod 132 is perpendicular to the axis of the replacement tray 15. The rotation axis of the clamping rod 132 is parallel to the axis of the replacement tray 15. The clamping rod 132 rotates towards the mounting groove 131 to press against the steel sheet wound on the replacement tray 15, thereby improving the positioning stability of the replacement tray 15 after installation.

[0047] During the actual material feeding process, after the steel sheets in the steel sheet tray 14 installed on the positioning shaft 12 are fed, the positioning component 6 releases the positioning between the positioning shaft 12 and the steel sheet tray 14, moves the steel sheet tray 14 away from the positioning shaft 12, and moves the sliding seat 13 closer to the positioning shaft 12 so that the positioning shaft 12 passes through the replacement tray 15 with the steel sheet wound on it. Then, the positioning component 6 positions and fixes the replacement tray 15 on the positioning shaft 12.

[0048] Reference Figure 4 and Figure 5 A pressure rod 16 slides and moves up and down on the frame 11. The pressure rod 16 is located above the positioning shaft 12. The pressure rod 16 slides closer to or away from the positioning shaft 12. An elastic element 161 is fixed on the frame 11. The elastic element 161 is located on the side of the pressure rod 16 away from the positioning shaft 12. The opposite ends of the elastic element 161 are fixedly connected to the frame 11 and the pressure rod 16, respectively. The elastic element 161 presses against the pressure rod 16, causing the pressure rod 16 to tend to move closer to the positioning shaft 12. During the feeding process, the elastic element 161 presses against the pressure rod 16, causing the pressure rod 16 to press against the steel sheet wound on the steel sheet tray 14, assisting in the positioning of the steel sheet. As feeding proceeds, the remaining amount of steel sheet gradually decreases, causing the pressure rod 16 to gradually move closer to the positioning shaft 12 under the action of the elastic element 161. In this embodiment, the elastic element 161 is a spring.

[0049] Reference Figure 4 and Figure 5 The positioning component 6 includes a limiting rod 61, a positioning pin 62, and a driving structure 63. The driving structure 63 includes a driving block 631, a rack 632, and a driving gear 633. The limiting rod 61 is rotatably connected to the positioning shaft 12, and the positioning pin 62 slides on the positioning shaft 12. The limiting rod 61 is located on the side of the positioning pin 62 near the sliding seat 13. The limiting rod 61 protrudes from the positioning shaft 12, and the rotation axis of the limiting rod 61 is perpendicular to the rotation axis of the positioning shaft 12. The limiting rod 61 rotates and fits against the side of the steel sheet tray 14 near the sliding seat 13 to limit the steel sheet tray 14. The sliding direction of the positioning pin 62 is perpendicular to the axis of the positioning shaft 12. The positioning pin 62 slides into or out of the positioning shaft 12. A positioning groove 141 is provided on the steel sheet tray 14, which allows the corresponding positioning pin 62 to be engaged and positioned. An elastic element 621 is fixed on the positioning shaft 12. The elastic element 621 pulls the end face of the positioning pin 62 near the rotating shaft of the positioning shaft 12, so that the positioning pin 62 has a tendency to move and extend into the positioning shaft 12. The opposite ends of the elastic element 621 are fixedly connected to the positioning shaft 12 and the positioning pin 62, respectively. In this embodiment, the elastic element 621 is a spring.

[0050] Reference Figure 4 and Figure 5The drive gear 633 is coaxially fixed on the limiting rod 61. The drive block 631 and the rack 632 are slidably connected to the positioning shaft 12. The drive block 631 is located on the side of the positioning pin 62 away from the sliding seat 13. The drive block 631 is cylindrical, and its axis is coaxial with the axis of the positioning shaft 12. A guide surface 622 is machined on the side of the positioning pin 62 near the drive block 631. The guide surface 622 is inclined and tilted away from the axis of the positioning shaft 12 in the direction closer to the drive block 631. The drive block 631 moves closer to or away from the positioning pin 62, thus positioning the drive block 631. An elastic element 121 is fixed on shaft 12. Elastic element 121 is located on the side of drive block 631 away from sliding seat 13. The opposite ends of elastic element 121 are fixedly connected to positioning shaft 12 and drive block 631, respectively. Elastic element 121 abuts against drive block 631, causing drive block 631 to tend towards positioning pin 62. The elasticity of elastic element 121 is greater than that of elastic element 621. Drive block 631 abuts against the guide surface 622 of positioning pin 62, causing positioning pin 62 to move away from the axis of positioning shaft 12, extending out of positioning shaft 12 and engaging into steel sheet tray 14. In this embodiment, elastic element 121 is a spring.

[0051] Reference Figure 4 and Figure 5 The rack 632 is located on the side of the drive block 631 near the sliding seat 13. The rack 632 is fixedly connected to the drive block 631. The rack 632 meshes with the drive gear 633. When the drive block 631 moves closer to the positioning pin 62, the drive block 631 drives the rack 632 to rotate towards the steel sheet tray 14 to fit the steel sheet box.

[0052] When the material tray needs to be replaced, the drive block 631 is moved away from the sliding seat 13, so that the drive block 631 moves away from the guide surface 622. After the drive block 631 moves away from the guide surface 622, the positioning pin 62 moves under the action of the elastic element 621 and extends into the positioning shaft 12. The movement of the drive block 631 drives the rack 632 to move. Through the meshing between the rack 632 and the drive gear 633, the limit rod 61 rotates away from the steel sheet material tray 14 and disengages from the steel sheet material tray 14. Then the steel sheet material tray 14 is moved to disengage from the positioning assembly 6.

[0053] The sliding seat 13 moves, carrying the replacement tray 15 with the steel sheet wound around it, closer to the positioning shaft 12. After the positioning shaft 12 and the limiting rod 61 pass through the replacement tray 15, the replacement drive block 631 is released, and the position of the replacement tray 15 is adjusted so that the positioning pin 62 moves and is locked into the positioning groove 141 under the action of the elastic element 121, the drive block 631 and the guide surface 622. When the positioning pin 62 is locked into the positioning groove 141, the limiting rod 61 rotates and abuts against the replacement tray 15 to limit the replacement tray 15, so that feeding can continue and the feeding can be convenient.

[0054] A sliding groove 112 is provided on the frame 11. The pressure rod 16 and the elastic element 161 are both located in the sliding groove. A guide surface 6311 is machined on the drive block 631. The guide surface 6311 is an annular surface and is arranged around the outer periphery of the drive block 631. The guide surface 6311 is inclined towards the positioning pin 62 along the axis near the positioning shaft 12. The guide surface 6311 is located in the sliding groove 112. An abutment block 162 is fixed on the side of the pressure rod 16 near the positioning shaft 12. The guide surface 6311 is located on the moving path of the abutment block 162. The abutment block 162 is used to abut against the guide surface 6311. The abutment block 162 drives the drive block 631 to move away from the positioning pin 62 through the guide surface 6311. The elasticity of the elastic element 161 is greater than that of the elastic element 162.

[0055] During the feeding process, the remaining amount of steel sheet gradually decreases. Under the action of the elastic element 161, the pressure rod 16 moves towards the positioning shaft 12, which in turn drives the abutment block 162 to move towards the guide surface 6311. When the abutment block 162 presses against the guide surface 6311, the pressure rod 16 continues to move, causing the drive block 631 to move away from the positioning pin 62 along the inclined direction of the guide surface 6311 until the pressure rod 16 abuts against the steel sheet tray 14. At this point, the drive block 631 disengages from the positioning pin 62, causing the positioning pin 62 and the limit rod 61 to disengage from the steel sheet tray 14, making it easier to replace the steel sheet tray 14.

[0056] The implementation principle of a multi-model steel sheet manufacturing motor core equipment in this application embodiment is as follows: In the actual material feeding process, after the steel sheet is unwound from the steel sheet tray 14, it passes through the detection frame 2 below the sensor 32, passes through each gap 43 to be leveled, and then passes through the correction device 5 and enters the discharge port 47 along the channel 442 to complete the feeding, so that the steel sheet passing through the discharge port 47 is flat, and the workpiece processed using the steel sheet is flat.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
