Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a punching processing device for a motor stator and rotor. Background Art

[0002] The punching processing device for the motor stator and rotor is a device used to punch sheet materials into motor stator and rotor punchings. Its structure generally includes a feeding mechanism, a punching mechanism, a mold, a discharging mechanism, and some auxiliary devices. The stamping equipment currently used for the motor stator and rotor punchings generally has two upper and lower molds. The upper and lower molds clamp and fix the punchings, and then increase the extrusion force. The set shape between the two molds enables the punching to complete the stamping process. However, in actual use, personnel are generally required to remove the punchings before and after processing and place new punchings to achieve material replacement. The equipment is shut down for a long time and the work efficiency is low. In addition, after the upper and lower molds are separated, the space between the two is the processing area. When switching, the personnel's hands are between the two molds. If the upper mold descends and accidentally touches or squeezes the staff, it will cause a major safety accident and pose a high safety hazard. Utility Model Content

On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0021] The following describes a punching processing device for a motor stator and rotor according to an embodiment of the present utility model in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, a punching processing device for a motor stator and rotor according to an embodiment of the utility model may include a support base 1, an L-shaped support frame 11, a hydraulic telescopic rod 12 and a punching assembly 2, the punching assembly 2 includes an upper mold 21 and two lower molds 22, a travel groove 13 is provided at the top of the support base 1, a support block 3 is slidably connected to the inner wall of the travel groove 13, and two processing grooves 31 are provided at the top of the support block 3.

[0023] The upper mold 21 is installed at the bottom of the hydraulic telescopic rod 12 , the lower mold 22 is slidably connected to the inside of the corresponding processing groove 31 , and the two lower molds 22 are alternately transferred to the bottom of the upper mold 21 .

[0024] It should be noted that the upper mold 21 described in this embodiment is perpendicular to the axis of the lower mold 22 thereunder, and the processing groove 31 is also perpendicular to the axis of the upper mold 21 .

[0025] Among them, the inner walls of the two processing grooves 31 are both installed with a central rod 32, and the lower mold 22 is slidably connected to the side wall of the corresponding central rod 32.

[0026] It should be noted that the center rod 32 described in this embodiment is consistent with the inner diameter of the lower mold 22 , and the processing groove 31 is consistent with the outer diameter of the lower mold 22 .

[0027] An annular groove 311 is formed at the bottom of the processing groove 31 , and a return spring 33 is provided in the processing groove 31 . The return spring 33 is connected to the bottom of the lower mold 22 at the top, and to the inner wall of the annular groove 311 at the bottom.

[0028] It should be noted that the internal axis of the return spring 33 described in this embodiment is consistent with the axis of the center rod 32.

[0029] Among them, two limiting grooves 312 are opened at the bottom of the processing groove 31 , and the inner walls of the two limiting grooves 312 are slidably connected with T-shaped limiting rods 34 , and the top of the T-shaped limiting rod 34 is installed at the bottom end of the lower mold 22 .

[0030] It should be noted that the bottom wide body of the T-shaped limiting rod 34 described in this embodiment is limited inside the limiting groove 312, and the T-shaped limiting rod 34 is vertically arranged.

[0031] Specifically, the support base 1 supports each component of the device, the L-shaped support frame 11 supports the hydraulic telescopic rod 12, and the hydraulic telescopic rod 12 controls the lifting of the upper mold 21 to facilitate the replacement of the punching material. The support base 1 accommodates and gives way to the support block 3 through the travel groove 13, and the support block 3 accommodates the two lower molds 22 through the two processing grooves 31. The support block 3 moves back and forth inside the L-shaped support frame 11, so that the two processing grooves 31 can drive the lower mold 22 to exchange with the bottom of the upper mold 21, so that the upper mold 21 can The middle rod 32 is inserted into the corresponding hole in the upper mold 21, and the annular groove 311 and the processing groove 31 accommodate the return spring 33. The return spring 33 supports the bottom of the lower mold 22, so that the lower mold 22 can automatically lift up when it is not under the pressure of the hydraulic telescopic rod 12 and the upper mold 21, so as to facilitate the removal of the punching sheet. The lower mold 22 carries the punching sheet raw material, and the middle rod 32 and the processing groove 31 together guide and limit the lower mold 22, so that the lower mold The lower die 22 is limited in position by the T-shaped limit rod 34 so that the T-shaped limit rod 34 cannot escape from the inner part of the limit groove 312. The T-shaped limit rod 34 drives the lower die 22 to limit so that the lower die 22 cannot escape from the processing groove 31 after reaching the upper limit. Moreover, after the lower die 22 reaches the upper limit, the height of the lower die 22 is lower than the middle rod 32, so that the punching sheet material can still be limited by the middle rod 32, preventing the punching sheet from shaking, facilitating positioning, taking and replacing, and passing through one of the processing grooves 31. When the hydraulic telescopic rod 12 and the upper die 21 are aligned for stamping, the punching sheet material is replaced in the processing groove 31 in the non-station area. The two areas work separately and do not interfere with each other. In addition, there is no need to replace the punching sheet in the stamping processing area, which reduces the risk of injury to personnel caused by the hydraulic telescopic rod 12 and the upper die 21, thereby improving operation safety. At the same time, by controlling the sliding of the support block 3, the two processing grooves 31 directly switch the working positions, so that the hydraulic telescopic rod 12 and the upper die 21 can process the next punching sheet more quickly, thereby improving work efficiency.

[0032] In one embodiment of the present invention, Figure 1-Figure 3 As shown, a connecting plate 36 is installed on one side of the support block 3, and the connecting plate 36 is slidably connected to the inner wall of the support base 1. A driving motor 4 is installed on one side of the support base 1, and a transmission screw 41 is installed on the output end of the driving motor 4, and the transmission screw 41 is threadedly connected to the inner wall of the connecting plate 36.

[0033] It should be noted that the connecting plate 36 described in this embodiment corresponds vertically to one side of the support block 3 , and the transmission screw 41 corresponds parallel to the support block 3 .

[0034] Specifically, the driving motor 4 drives the transmission screw 41 to rotate. When the transmission screw 41 rotates, it can drive the connecting plate 36 to complete the lateral movement, so that the connecting plate 36 can drive the support block 3 to complete the sliding, and the support block 3 drives the two processing grooves 31 to complete the work station switching, thereby realizing rapid material change.

[0035] In one embodiment of the present invention, Figure 2-Figure 3 As shown, a plurality of spherical rolling bodies 361 are provided at the upper and lower ends of the connecting plate 36, and the spherical rolling bodies 361 are slidably connected to the inner wall of the support base 1. A plurality of moving wheels 35 are installed at the bottom of the support block 3, and the plurality of moving wheels 35 are slidably connected to the inner wall of the bottom side of the travel groove 13.

[0036] It should be noted that the moving wheel 35 described in this embodiment weighs the support block 3 , while the connecting plate 36 does not bear the weight of the support block 3 .

[0037] Specifically, when the connecting plate 36 slides inside the support base 1, the connecting plate 36 drives several spherical rolling bodies 361 to slide, and the several spherical rolling bodies 361 are located between the connecting plate 36 and the inner wall of the support base 1, thereby reducing the sliding friction resistance and friction loss between the connecting plate 36 and the support base 1. The support base 1 supports the support block 3 through several action wheels 35 to facilitate the lateral movement of the support block 3.

[0038] In one embodiment of the present invention, Figure 1-Figure 2 As shown, an inspection slot 14 is provided on one side of the support base 1 , a cover plate 141 is installed at the opening of the inspection slot 14 , a transmission screw 41 is located inside the inspection slot 14 , and two tool storage slots 15 are provided on the top of the support base 1 .

[0039] It should be noted that the cover plate 141 described in this embodiment is flipped downward to open the inspection slot 14 .

[0040] Specifically, the cover 141 makes way for the connection area between the transmission screw 41 and the connecting plate 36. By opening the cover 141, the space of the inspection slot 14 is opened, which facilitates the inspection of the connecting plate 36 and the transmission screw 41. The two tool storage slots 15 can hold accessories or tools used during operation for timely access.

[0041] In one embodiment of the present invention, Figure 1-Figure 4 As shown, several anti-interference infrared sensors 5 are installed at the bottom of the L-shaped support frame 11, and several anti-interference infrared sensors 5 are surrounded by the axis of the hydraulic telescopic rod 12. An audible and visual alarm 51 controlled by the anti-interference infrared sensor 5 is installed at the top of the support base 1, and a protective baffle 37 is installed at the top of the support block 3. The protective baffle 37 is located between the two processing grooves 31.

[0042] It should be noted that the plurality of anti-interference infrared sensors 5 described in this embodiment are distributed in a circular array, and the anti-interference infrared sensors 5 transmit signals to the equipment control center and the sound and light alarm 51 via wired signals.

[0043] Specifically, the range covered by the anti-interference infrared sensor 5 is larger than the outer ring size of the upper mold 21. The anti-interference infrared sensor 5 irradiates infrared light on the top of the support block 3. Through a stable sensing distance, the anti-interference infrared sensor 5 can detect whether there are any obstacles downward. When external objects or personnel accidentally reach the space between the upper mold 21 and the support block 3, the anti-interference infrared sensor 5 senses it in time, and the anti-interference infrared sensor 5 releases a control signal to the sound and light alarm 51 and the equipment control system, so that the sound and light alarm 51 issues an alarm in time to remind personnel to leave the working area to avoid injury. At the same time, the equipment automatically suspends operation. In addition, the protective baffle 37 separates the two processing grooves 31 into a space to prevent personnel from reaching the working area below the upper mold 21, further improving safety.

[0044] In summary, in the punching processing device for the stator and rotor of the motor of the embodiment of the utility model, when the device is in use, one of the processing grooves 31 is vertically aligned with the bottom of the upper mold 21, and the hydraulic telescopic rod 12 controls the upper mold 21 to descend, and the upper mold 21 and the lower mold 22 complete the punching processing of the punch. At the same time, the other processing groove 31 is in the non-processing area, and the punched sheet after processing in the processing groove 31 is taken out, and then a new punched sheet is placed to complete the replacement. The transmission screw 41 drives the support block 3 to slide again through the connecting plate 36, and the support block 3 drives the two processing grooves 31 and the two lower molds 22 to switch work, so that the hydraulic telescopic rod 12 and the upper mold 21 can process the next punched sheet more quickly, thereby improving work efficiency. The protective baffle 37 separates the two processing grooves 31 into a space, blocking personnel from reaching the working area below the upper mold 21, thereby further improving work safety.
