The invention relates to a stamping device with deburring and stacking functions, and belongs to the technical field of stamping devices. Comprising a base, a feeding mechanism is arranged on the side edge of the base, a stamping machine body is installed on the base, a stamping mechanism for stamping and cutting coil stock on the feeding mechanism is installed on the stamping machine body, and a conveying mechanism is arranged on the bottom side of the stamping mechanism and used for conveying stamped sheets to a stacking mechanism; the stamping machine body comprises a movable mold plate, a fixed mold plate and a connecting rod, the stamping mechanism comprises an upper pressing mold and a lower pressing mold, the feeding mechanism comprises a feeding support and a material collecting support, the conveying mechanism comprises a first conveying belt, a grinding wheel assembly and a second conveying belt, the stacking mechanism comprises an inner ring component, a first telescopic motor, an arc-shaped plate and a lifting head, and a discharging mechanism is further arranged. According to the stamping piece stacking device, the stamping pieces are subjected to stamping piece cutting, deburring, stacking, discharging and other operations, the stamping pieces stacked in a staggered mode can be effectively smoothed, and the technical effects of efficient machining and orderly stacking of the stamping pieces are achieved.

The invention relates to the technical field of burr cleaning, in particular to a high-pressure jet system which comprises a high-pressure pump, a liquid supply pipeline, a nozzle, a pulse pressurizing mechanism and a controller, and one end of the liquid supply pipeline communicates with the output end of the high-pressure pump; the nozzle communicates with the end, away from the high-pressure pump, of the liquid supply pipeline. The pulse pressurizing mechanism is arranged on the liquid supply pipeline; and the controller is electrically connected with the high-pressure pump and the pulse pressurization mechanism and used for controlling the movement frequency of the pulse pressurization mechanism to be matched with the pressure pulsation frequency of the high-pressure pump so that a medium sprayed out of the nozzle can be in a pulse pressurization state. Pulse pressurization can be obtained with small energy consumption, and the impact damage capacity to hard burrs is improved.

The utility model discloses a graphite plate deburring tool, related to stamping die technical field, including work table, work table includes lower die holder and sets up the upper die holder in the upper of lower die holder, and is provided with the installation site of installing graphite plate in lower die holder, and the upper die holder includes fixed plate, drive mechanism and stamping mechanism, and the stamping mechanism includes stamping base and punch, and the stamping base is connected with drive mechanism, and the punch is connected with the side of the stamping base to lower die holder, and the punch has the stamping inner ring assembly close to the center of punch, and the stamping outer ring assembly is set up in the outer periphery of stamping inner ring assembly, and the graphite plate is pressed down by drive mechanism drive stamping mechanism to graphite plate, so that the stamping outer ring assembly of punch can stamp the outer ring of graphite plate to remove the outer ring burr of graphite plate, and make the stamping inner ring assembly stamp the through -hole of graphite plate to remove the burr of through -hole.

The invention relates to the technical field of semiconductor equipment cleaning, in particular to a cleaning method for a polymer deposited on an aluminum-based silicon carbide shower head. According to the cleaning method, sediments on the inner wall of the gas uniformizing opening are efficiently removed through silicon carbide sand blasting, a protection water column is formed during grinding through a water grinding jig to prevent secondary pollution of particles, and adhesive microparticles are thoroughly removed through gap nitrogen purging. Compared with a traditional method, the method has the advantages that the sediment removal time is greatly shortened to 0.2-0.5 h from 4-6 h, the number of microparticles (particles with the particle size larger than or equal to 0.2 micrometer) on the surface of the cleaned shower head is remarkably superior to the standard limit value, and therefore the cleaning efficiency and reliability are greatly improved while the ultrahigh cleanliness is guaranteed.
