[0002] DC micro motor brush holders are used on the commutator or slip ring of a motor as sliding contacts for conducting current. Their main function is to conduct electricity while rubbing metal together. They are widely used in various AC and DC generators, synchronous motors, battery-powered DC motors, crane motor slip rings, various types of welding machines, etc. As the use of DC micro motors becomes more and more widespread, the production of DC micro motor brush holders is becoming more and more mechanized.

[0003] In the production of DC micro motor brush holders, the brush plate is typically placed on a conveying mechanism and stamped using different types of dies. During the stamping process, after repeated use, the die surface often retains a large amount of dust and debris, and the die surface temperature is high. This results in poor overall stability of the die, affecting the overall quality of the DC micro motor brush holder. Brush holders stamped at high temperatures are of poor quality. Therefore, this application provides a multi-station progressive stamping DC micro motor brush holder production device to meet the requirements. Summary of the Invention

[0016] This utility model embodiment provides a technical solution: Please see Figure 1-6 A multi-station progressive stamping DC micro motor brush holder production apparatus includes a conveying mechanism for conveying a material plate 9, and a progressive stamping die 4 mounted on the conveying mechanism for progressively stamping the material plate 9 to form a DC micro motor brush holder. The progressive stamping die 4 consists of an upper die 401, a lower die 403, and a guide post 402 located between the upper die 401 and the lower die 403. A sliding stabilizing mechanism 5 is mounted on the outside of the progressive stamping die 4. The sliding stabilizing mechanism 5 is mounted on the conveying mechanism, and a drive unit is mounted on the sliding stabilizing mechanism 5. The drive unit is used to drive the progressive stamping die 4 to run smoothly to achieve DC-DC... Micro motor brush holder production; the sliding stabilization mechanism 5 includes a vertical plate assembly and a support plate 501. The vertical plate assembly is provided in at least two sets, and both sets of vertical plate assemblies are vertically erected on the conveying mechanism. Each set of vertical plate assemblies consists of a left vertical plate 502 located on the left side of the progressive stamping die 4 and a right vertical plate 503 located on the right side of the progressive stamping die 4. The support plate 501 is horizontally placed on the vertical plate assembly. The top view of the support plate 501 is rectangular, and the side view of the left vertical plate 502 and the right vertical plate 503 is rectangular. This utility model provides stable support for the support plate 501 by setting four vertical plates, namely two sets of left vertical plates 502 and two sets of right vertical plates 503.

[0017] Furthermore, the sliding stabilization mechanism 5 also includes two sets of sliding parts. Each set of sliding parts consists of a connecting shaft 505 and a pulley 504 sleeved on the outer wall of the connecting shaft 505. Sliding holes 5031 are provided on the side walls of the left vertical plate 502 and the right vertical plate 503 along their height direction. The outer wall of the pulley 504 is attached to the cavity of the sliding hole 5031. The pulley 504 can roll up and down along the extension direction of the cavity of the sliding hole 5031 to drive the upper die 401 to perform stable stamping on the lower die 403. Through the cooperation of the pulley 504 and the connecting shaft 505, the upper die 401 is limited and protected on both sides, so that the upper die 401 is stably placed between the left vertical plate 502 and the right vertical plate 503, avoiding wear on both sides of the die body when the upper die 401 moves up and down, extending the service life of the upper die 401, and improving the robustness and durability of the progressive stamping die 4.

[0018] Furthermore, the conveying mechanism is provided with at least two sets, and each set of conveying mechanism is equipped with a progressive stamping die 4, a sliding stabilizing mechanism 5 and a drive unit. The conveying mechanism is a belt conveyor composed of a conveyor table 1, a transmission belt 2 and a drive motor 3. A control box 10 is installed on the back of the conveyor table 1, and a controller for controlling the operation of the drive motor 3 and the drive unit is installed in the control box 10. The belt conveyor is a stepper type conveyor, and the drive motor 3 is a stepper motor.

[0019] Furthermore, the drive unit consists of a cylinder protection box 6 mounted on the support plate 501 and a pressing cylinder 7 vertically placed inside the cylinder protection box 6. The bottom end of the piston rod 701 of the pressing cylinder 7 passes vertically through the support plate 501 and is fixedly connected to the top of the upper mold 401. The pressing cylinder 7 is used to drive the upper mold 401 to press the lower mold 403 downward. The top of the cylinder protection box 6 is provided with heat dissipation holes 601 at intervals, so that when the pressing cylinder 7 is used for a long time, the heat dissipation holes 601 can be used to disperse the heat accumulated on the surface of the pressing cylinder 7 during use. The cylinder protection box 6 can effectively protect the pressing cylinder 7, blocking the corrosion caused by external dust and moisture to the pressing cylinder 7, thereby extending the service life of the pressing cylinder 7. The pressing cylinder 7 adopts a commonly used specification in the market, such as an SMC type standard cylinder or a one-way cylinder, which is also applicable to this embodiment. The structure and principle of the pressing cylinder 7 are well known technologies in the market, so they will not be described in detail here.

[0020] Furthermore, a support portion 11 is installed on the front of the upright plate assembly, and a dust removal mechanism 8 is installed on the front of the support portion 11. The dust removal mechanism 8 is used to dissipate heat and remove dust from the progressive die 4 in use. The support portion 11 consists of a transparent plate 1101 and a through hole 1103 formed in the transparent plate 1101. The transparent plate 1101 is detachably connected to the front of the upright plate assembly by fasteners 1102. The transparent plate 1101 can serve as a support plate while allowing a direct view of the progressive die 4 in use, thus facilitating the maintenance of the progressive die 4. The fasteners 1102 are, but are not limited to, screws, bolts, or bolts.

[0021] Furthermore, the dust removal mechanism 8 consists of a dust collection box 801, a conduit 802 that communicates with the interior of the dust collection box 801 and is installed on the back of the dust collection box 801, and a suction head 803 located on the back of the support part 11 and communicating with the conduit 802. The suction head 803 is located on the front of the progressive die 4 and is used to suck up the dust and debris generated when the progressive die 4 is in use. The dust removal mechanism 8 can dissipate heat and suck up dust on the progressive die 4, greatly reducing the dust on the surface of the progressive die 4, and also blowing away the high temperature heat of the progressive die 4 and performing heat dissipation treatment on the progressive die 4.

[0022] In use, the two sets of conveyor tables 1 are combined into one, and the drive motor 3 simultaneously drives the transmission belts 2 on the two sets of conveyor tables 1 to realize the step-by-step transmission of the DC micro motor brush holder material plate 9. This allows the material plate 9 to be step-by-step transmitted to the progressive stamping die 4 for progressive stamping. The belt conveyor transports the material plate 9 into the progressive stamping die 4, which has multiple working cavities. The control box 10 is used to start the pressing cylinder 7 and the dust removal mechanism 8. When the pressing cylinder 7 is running, it drives the upper die 401 to press towards the lower die 403. The material plate 9 is stamped by the progressive stamping die 4 in multiple working cavities to form the DC micro motor brush holder. After the material plate 9 has passed through the progressive stamping die 4, the resulting DC micro motor brush holder falls onto the transmission belt 2, and then the conveying mechanism transports the DC micro motor brush holder to the subsequent production process. When the progressive die 4 is performing progressive stamping, the dust removal mechanism 8 can be activated to suck the dust and debris inside the progressive die 4 into the dust collection box 801, so as to prevent the dust and debris generated during progressive stamping from affecting the progressive die 4 to perform progressive stamping of the material plate 9 again. The dust removal mechanism 8 is a vacuum cleaner installed in the dust collection box 801. When the vacuum cleaner is activated, it generates suction, and the suction head 803 sucks in the dust and debris and quickly enters the dust collection box 801 through the conduit 802. The vacuum cleaner is a device that uses an air pump to create a partial vacuum, generate suction, and pick up dust and debris from the floor or other locations. The structural principle of the vacuum cleaner is a well-known technology in the market, so it will not be described in detail here.

[0023] In summary, this utility model features convenient use, high production efficiency, and high quality of DC micro motor brush holders. Through the cooperation of the sliding stabilization mechanism 5 and the pressing cylinder 7, the overall stability of the upper die 401 during its vertical movement is improved, ensuring that the upper die 401 remains balanced and stable throughout use. This results in a smoother and flatter surface on the stamping edge of the DC micro motor brush holder obtained by the upper die 401 when stamping the lower die 403, greatly improving the production quality of the DC micro motor brush holder. Furthermore, it also improves the surface quality of the brush holders produced by the upper die 401 on both sides. The limit protection ensures that the upper die 401 is stably placed between the left vertical plate 502 and the right vertical plate 503, preventing wear on both sides of the die body when the upper die 401 moves up and down, extending the service life of the upper die 401, and improving the sturdiness and durability of the progressive stamping die 4. At the same time, the dust removal mechanism 8 can dissipate heat and remove dust from the progressive stamping die 4, solving the technical problems in the prior art of poor stability of the stamping die during use, affecting the overall quality of the DC micro motor brush holder, and poor quality of the DC micro motor brush holder stamped by the stamping die at high temperature.
