A support bag 210 with multiple powder leakage holes 211 is fixed on 201; another pair of electric push rods 201 are fixed with a support net 220, the other end of which is hinged to the two side walls of the inclined slide table 200; the support net 220 is composed of multiple air-bag type expansion tubes connected in an interlaced manner, with the gaps between the interlaced air-bag type expansion tubes at the end away from the support bag 210 being dense, and the gaps between the interlaced tubes at the end closer to the support bag 210 being loose; its function is to prevent the damaged part of the workpiece 120 from scratching other intact workpieces 120;

[0027] Two dual-purpose air pumps 230 are installed on the side wall of the fixed platform 100, and the dual-purpose air pumps 230 are connected to the support net 220 through the connecting pipe 231.

[0028] The inclined slide 200 has a protrusion 2001 at the corresponding position of the support bag 210. Its function is to lift the workpiece 120, adjust the position of the workpiece 120 on the support bag 210, and play a guiding role.

[0029] The inclined slide 200 has multiple collection holes 202 on its surface corresponding to the support bag 210 and the support net 220; and a wide groove 203 is opened at the corresponding position of the loose area of ​​the staggered gap of the support net 220; the function is to collect dust.

[0030] A collection frame 204 is slidably connected inside the inclined slide 200, and the length of the collection frame 204 is longer than half of the inclined slide 200; its function is to collect dust and damaged parts of the workpiece 120, and to prevent the intact workpiece 120 from being covered by dust and scratched.

[0031] The grinding assembly includes an electric slider 130, a rotating rod 131, a fixed base 132, and a grinding mold 133. The electric slider 130 is symmetrically slidably connected in the guide groove 101. A rotating rod 131 is installed on the electric slider 130. A rotating motor is installed on one of the rotating rods 131. A fixed base 132 is fixed between the two rotating rods 131. The grinding mold 133 is detachably mounted on both sides of the fixed base 132.

[0032] The material feeding assembly includes an electric push rod 140, a push plate 141, and a powder guiding tube 142; the electric push rod 140 is installed on the top of the side wall of the fixed platform 100, and the push plate 141 is fixed to the output end of the electric push rod 140; one end of the powder guiding tube 142 passes through the push plate 141, and the other end is connected to the material discharging device.

[0033] A hydraulic rod 111 is installed on the bottom surface of the fixed platform 100 at the corresponding position of the stamping machine 110. A support platform 112 is installed on the hydraulic rod 111 to support the fixed seat 132.

[0034] The support bag 210 is made of conductive silicone rubber. An electrostatic generator 240 is installed on the support bag 210 to adsorb excess dust on the workpiece 120. The support bag 210 has an inner cavity 212, in which multiple top blocks 213 are fixed and located away from the end of the press 110. The purpose of the top blocks 213 is to make the workpiece 120 roll so that excess dust in the holes and on the surface of the workpiece 120 can be adsorbed by electrostatics.

[0035] Specific implementation: First, the grinding assembly moves to the position corresponding to the feeding assembly, and the feeding device connected to the electric push rod 140 and the powder guide pipe 142 is activated, causing the powder to fall into the grinding mold 133 and be spread evenly; after spreading, the electric push rod 140 retracts, the feeding device connected to the powder guide pipe 142 stops feeding, the grinding assembly moves back to the initial position, the hydraulic lever 111 is activated to drive the support platform 112 to move upward and support the fixed seat 132, and then the press 110 is activated to press down, so that the powder is dry-pressed and formed, and then lifted. The stamping press 110, the unloading assembly moves again to the position corresponding to the unloading assembly, and the rotating motor on one of the rotating rods 131 rotates, driving the fixed seat 132 to rotate. When the workpiece 120 falls onto the support bag 210 and the electrostatic generator 240 is activated, the support bag 210 will bend and deform due to the gravity of the workpiece 120. Under the action of bending, the top block 213 pushes up the surface of the support bag 210 at the corresponding position, so that the workpiece 120 has resistance when sliding. On a pair of electric push rods 201 The lifting mechanism raises one end of the support bag 210 while the other end lowers, pushing the workpiece 120 to contact and roll against the raised top block 213. Excess dust inside and on the surface of the rolling workpiece 120 is attracted by static electricity. After the workpiece 120 rolls onto the support net 220, the static generator 240 is turned off, and the electric push rod 201 connected to the support net 220 descends, causing the dust on the workpiece 120 to fall through the collection hole 202 into the collection frame 204 for collection. The workpiece 120 then passes through the inclined slide 2... 00 Slide to the collection process; when the workpiece 120 is hit and the damaged part falls and rolls onto the support net 220, the dual-purpose air pump 230 causes the airbag-type expansion tube to expand or contract, so that the damaged part falls into the collection frame 204 through the gap. When the damaged part is too large, the electric push rod 201 lifts it up and makes the damaged part roll into the gap loose area. Then, the airbag-type expansion tube in the gap loose area expands or contracts, so that the damaged part falls into the collection frame 204 through the wide groove 203.

[0036] Beneficial effects: Through the coordinated lifting and lowering of two pairs of electric push rods 201, the support bag 210 can effectively wrap the workpiece 120, and the top block 213 can make the workpiece 120 roll. The rolling of the workpiece 120 can help the dust adhering to its internal holes or surface to be attracted by the electrostatic generator 240. The support net 220, which is formed by multiple airbag-type expansion tubes connected in an interlaced manner, can expand or contract, so that the damaged parts of the workpiece 120 can fall into the collection frame 204 through the gaps, preventing the intact workpiece 120 from being scratched by the damaged parts.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
