During the stamping operation, there will be a problem that magnetic powder adheres to the punch. If it is not cleaned for a long time, the quality of the formed magnetic block will be affected, and the die will be damaged. To solve this technical problem, currently, manual maintenance and cleaning of the punch are carried out regularly. This manual maintenance and cleaning method increases production costs and reduces production efficiency. Summary of the Utility Model

[0027] Refer to Figures 1 to 2 To further describe the embodiments of the present utility model.

[0028] The specific structure of this embodiment: It includes a first power unit, a connecting seat, a second power unit, an arm and an output unit.

[0029] Among them, the first power unit includes a motor and a lead screw. The bottom of the connecting seat is connected to the nut of the lead screw. One side of the second power unit is connected to the connecting seat. The second power unit is a cylinder, and the output end of the cylinder is connected to the arm, so as to be able to control the arm to move up and down.

[0030] The output unit includes a base and guide rods. The base is sleeved on the guide rods and can move up and down along the guide rods. There are two guide rods, and they are arranged on both sides of the base. The guide rods are connected to the ends of the arm. A first spring is provided between one side end face of the base and one end face of the arm. The two ends of the first spring are respectively connected to the base and the arm. When the base is forced to press down on the first spring, the first spring will be compressed. When the base is no longer forced to press, it will be reset by the first spring.

[0031] A scraper is installed on one side edge of the top surface of the base. A material receiving box is provided near the scraper. One side of the material receiving box is fixed on the side wall of the base. The cutting edge of the scraper is higher than the edge of the material receiving box, which is convenient for the scraper to scrape the powder material on the sticky material part (i.e., the punch, hereinafter referred to as the punch) and fall into the material receiving box. A brush body is installed at one end of the arm near the output unit, which is used to clean the punch after the output unit has scraped the powder material.

[0032] A cavity is formed downward on the top surface of the pedestal. A heaving member is movably connected in the cavity. A second spring is provided between the bottom of the heaving member and the bottom of the cavity, and both ends of the second spring are respectively connected to the bottom of the heaving member and the bottom of the cavity.

[0033] The two side walls of the upper part of the heaving member contract inward to form symmetric opening workstations. A workstation hole is formed in the lower part of the heaving member. Rollers are movably connected to the opening workstations. The two rollers are bearings. The two sides of the upper part of the heaving member are connected to the rollers through shaft rods, and the rollers can rotate relative to the shaft rods.

[0034] An activity opening is formed on the pedestal. The activity opening communicates with the cavity. The length of the activity opening is set according to the lifting distance of the heaving member. There is a thread inside the workstation hole. A pin rod is threadedly connected to the workstation hole. One end of the pin rod extends out of the activity opening, and a locking cap is connected to this end. The diameter of the locking cap is greater than the width of the activity opening. By rotating the locking cap to connect with the workstation hole, the locking cap and the outer end face of the pedestal are squeezed to lock the heaving member at a specified height. When adjusting the heaving member to a specified height, if the second spring is squeezed downward, the second spring will be compressed. When the height of the heaving member needs to be increased, the locking cap is loosened, and the heaving member will be lifted by the second spring.

[0035] During use, the motor drives the control connecting seat to move towards the processing die, so that the arm drives the scraper to perform a feeding action. The scraper will contact the punch. When the arm feeds, the scraper will scrape off the powder on the punch. After the powder falls, it will enter the material receiving box below it. Before this dynamic process, according to the height of the punch, the heaving member is adjusted to the corresponding height, so that the scraper can remove the powder adhering to the punch. If there is no powder on the punch, the scraper will not touch the punch.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any normal changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
