Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel shot processing, in particular to a multi-stage processing type stainless steel shot processing device. Background Art

[0002] Stainless steel shots are generally heated by stainless steel bars, cut into corresponding sizes, and then punched into spherical shapes by stamping and shaping equipment. After being processed into spherical shapes, they are sent to the tempering furnace for heat treatment. After heat treatment, they are sent to the grinding equipment to grind the rough surfaces to form stainless steel shots with smooth surfaces. Finally, the stainless steel shots are sent to the polishing equipment for polishing. Stainless steel shots are often used in bearing processing, etc. Therefore, after the processing of stainless steel shots, they need to be screened by size and tested for surface accuracy to complete the processing and production.

[0003] A patent with publication number CN116810616B discloses a multi-stage processing stainless steel ball processing device, which places the tempered stainless steel balls between the lifting grinding disc and the reversing chassis and presses them, and then the lifting grinding disc and the reversing chassis make circular motions in opposite directions, so as to quickly grind the stainless steel balls between the lifting grinding disc and the reversing chassis, effectively shorten the grinding time, and ensure the surface quality of the ground stainless steel balls;

[0004] In the above scheme, when the lifting grinding disc and the reversing chassis make circular motions in opposite directions and grind the stainless steel balls, the rotating plate can drive the steering rotating special-shaped ring to make circular motions in the opposite direction to the rotation of the reversing chassis, and provide a horizontal or inclined horizontal rotational force to the stainless steel balls being ground between the lifting grinding disc and the reversing chassis, so that the steel balls roll in an unfixed direction, so that the surface of the stainless steel balls can be completely ground, thereby ensuring the surface quality of the stainless steel balls after grinding.

[0005] There are still some problems in practical application. When grinding stainless steel shots, they are usually transported to a tray one by one, and limiting annular stripes are set on the tray to separate the position of each stainless steel shot. Then the grinding disc is driven to move downward to press down the stainless steel shots on the tray, and at the same time, the grinding disc is driven to rotate to grind the stainless steel shots. However, this grinding process is not a cyclic grinding process, which requires the grinding stainless steel shots to be collected centrally, and then the next batch of stainless steel shots are added for grinding. Not only is the grinding efficiency slow, but the operation is also cumbersome and inconvenient.

[0006] To this end, the present invention provides a multi-stage processing type stainless steel shot processing equipment. Summary of the invention

The material receiving rack is configured as a foldable material receiving rack, which can be used to seal the discharge port.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. A multi-stage processing stainless steel shot processing equipment described in the present invention. The semi-finished stainless steel shot after being returned to the furnace is conveyed into the inner cavity of the feed port, and falls into the grinding cavity through the feed port, and then the rotating disk is driven to rotate, and the semi-circular limit groove is used to drive the semi-finished stainless steel shot to rotate synchronously, so that the semi-finished stainless steel shot generates friction with the grinding sheet and the grinding sand sheet during the movement, and when the semi-circular limit groove drives the semi-finished stainless steel shot to move, the semi-finished stainless steel shot will rotate irregularly, so that the entire surface can be quickly and effectively polished, thereby solving the problem that the existing multi-stage processing stainless steel shot processing equipment usually polishes the stainless steel shot one by one, and this polishing process is not a cyclic polishing process, resulting in the need to collect the polished stainless steel shot in a centralized manner, and then polish it, which not only has a slow polishing efficiency, but also affects the processing efficiency of the stainless steel shot.

[0020] 2. A multi-stage processing stainless steel shot processing equipment described in the present invention. After the semi-finished stainless steel shot is polished, the stainless steel shot will fall into the inner cavity of the protective shell through the connecting groove, and then the stainless steel shot will be driven to rotate in the inner cavity of the protective shell. At the same time, when the stainless steel shot rotates to the installation groove, the stainless steel shot contacts the sponge pad, and the sponge pad applies the polishing agent on the surface of the stainless steel shot. At the same time, as the stainless steel shot is continuously driven to rotate in the inner cavity of the protective shell, the stainless steel shot is polished with polishing sandpaper, thereby solving the problem that the stainless steel shot processing equipment needs to collect the polished stainless steel shot after the semi-finished stainless steel shot is polished. After the stainless steel shot is polished, the collected stainless steel shot is put into the polishing machine, and the polishing agent is added to drive the stainless steel shot to rotate and polish it. Although this polishing efficiency is fast, the stainless steel shots collide with each other in the polishing machine to produce scratches or collision marks, which affects the quality of the stainless steel shot and also causes the waste of polishing agent.

[0031] Specifically, in the prior art, when grinding stainless steel shots, the stainless steel shots are usually delivered to a tray one by one, and a limiting annular stripe is also set on the tray to separate the position of each stainless steel shot, and then the grinding disc is driven to move downward to press down the stainless steel shot on the tray, and at the same time, the grinding disc is driven to rotate to grind the stainless steel shot. However, this grinding process is not a cyclic grinding process, which requires the grinding stainless steel shots to be collected and then replenished with the next batch of stainless steel shots for grinding. Not only is the operation cumbersome and inconvenient, but the grinding efficiency is also low.

[0032] The present invention transports the semi-finished stainless steel shot after recycling into the inner cavity of the feed port 29, and makes the semi-finished stainless steel shot fall into the grinding cavity 28 through the feed port 29, and then drives the rotating column 23 to rotate, and makes the rotating column 23 drive the rotating disk 24 to rotate, and the rotating disk 24 is evenly provided with a plurality of semicircular limiting grooves 27 on the outside, and then during the rotation of the rotating disk 24, the semi-circular limiting grooves 27 are used to drive the semi-finished stainless steel shot to rotate synchronously, so that the semi-finished stainless steel shot can generate friction with the grinding sheet and the grinding sand sheet 30 during the movement, so that the semi-finished stainless steel shot is polished smooth during the movement, and the semi-finished stainless steel shot is driven to rotate by the semi-circular limiting grooves 27. After one circle, the polished semi-finished stainless steel shot will be discharged into the inner cavity of the protective shell 1 through the connecting groove 26, and then the polished stainless steel shot will be driven to rotate clockwise in the inner cavity of the protective shell 1, so that the polished stainless steel shot is polished in the inner cavity of the protective shell 1, thereby solving the problem that the existing multi-stage processing stainless steel shot processing equipment usually polishes the stainless steel shot one by one when polishing the stainless steel shot, and this polishing process is not a cyclic polishing process, which leads to the need to collect the polished stainless steel shot in a centralized manner and then polish it, which not only has slow polishing efficiency but also affects the processing efficiency of the stainless steel shot.

An insert block 25 is fixedly connected to the output shaft end of the servo motor 13, and the insert block 25 is inserted into the inner cavity of the rotating column 23.

[0034] like Figure 2 and Figure 4 As shown, a guide rack 15 is installed on one end surface of the grinding cylinder 7 outside the feed port 29, and the inner cavity of the guide rack 15 is connected to the feed port 29, and the guide rack 15 is arranged in an S shape for conveying semi-finished stainless steel shots.

[0035] Specifically, the semi-finished stainless steel pills are conveyed into the inner cavity of the guide rack 15 by using an external conveyor belt or a hoist, and then the semi-finished stainless steel pills are conveyed by using the S-shaped guide rack 15, so that the semi-finished stainless steel pills slide in an S shape to speed up and quickly slide into the inner cavity of the feed port 29, and the excess semi-finished stainless steel pills are stored side by side in the inner cavity of the guide rack 15, and enter the inner cavity of the feed port 29 one by one, thereby achieving the effect of automatic unloading, and then the servo motor 13 is started to drive the plug block 25 to rotate, and the plug block 25 drives the rotating column 23 to rotate, and then the rotating column 23 drives the rotating disk 24 to rotate, and at the same time the rotating disk 24 moves the semi-finished stainless steel pills for grinding, thereby improving the processing efficiency of the semi-finished stainless steel pills.

[0036] like Figures 2 to 4 As shown, polishing sandpaper 31 is arranged on the outside of the grinding cylinder 7, polishing sandpaper 31 is arranged on the inner wall of the protective shell 1, and the polishing sandpaper 31 can be replaced according to demand.

[0037] like Figure 2 and Figure 4 As shown, a mounting groove 19 is opened at the upper end of the protective shell 1, and a threaded hole 20 is opened at the bottom of the inner cavity of the mounting groove 19, the mounting groove 19 is connected with the inner cavity of the protective shell 1, a mounting plate 2 is installed in the inner cavity of the mounting groove 19, and a sponge pad 18 is installed on the lower end surface of the mounting plate 2, and the sponge pad 18 is inserted in the inner cavity of the mounting groove 19.

[0039] Specifically, after the semi-finished stainless steel shot is polished, the stainless steel shot will fall into the inner cavity of the protective shell 1 through the connecting groove 26, and then the stainless steel shot will be driven to rotate in the inner cavity of the protective shell 1. At the same time, when the stainless steel shot rotates to the mounting groove 19, the stainless steel shot will contact the sponge pad 18, and the polishing agent is stored in the inner cavity of the storage box 16, and the polishing agent will flow into the sponge pad 18 through the through hole 32 for storage. After the stainless steel shot contacts the sponge pad 18, the sponge pad 18 applies the polishing agent to the surface of the stainless steel shot. At the same time, as the stainless steel shot is continuously driven to rotate in the inner cavity of the protective shell 1, the stainless steel shot is polished and polished using the polishing sandpaper 31. Moreover, the stainless steel shot rotates irregularly in the inner cavity of the protective shell 1, so that the surface of the entire stainless steel shot can be effectively polished, and the efficiency of the surface polishing of the stainless steel shot is improved, thereby solving the problem that the stainless steel shot processing equipment needs to collect the polished stainless steel shots after the semi-finished stainless steel shots are polished. After the stainless steel shots are polished, the collected stainless steel shots are put into the polishing machine, and polishing agent is added to drive the stainless steel shots to rotate and polish them. Although this polishing efficiency is fast, the stainless steel shots rotate and collide with each other in the polishing machine to produce scratches or collision marks, which affects the quality of the stainless steel shots and also causes the waste of polishing agent.

During the rotation of the ring gear 4, it will drive the fixed block 3 to rotate synchronously, and at the same time, the fixed block 3 drives the pushing column 21 to rotate in the inner cavity of the protective shell 1, and the pushing column 21 uses the rotating shaft 22 to drive the limiting pulley 34 to slide in the inner cavity of the T-shaped slide groove 35, and then the pushing column 21 pushes the stainless steel shot in the inner cavity of the protective shell 1 to roll, and then the stainless steel shot is polished during the rolling process, thereby improving the efficiency of the stainless steel shot processing and production.

[0046] The working principle is to convey the semi-finished stainless steel pills after the remelting into the inner cavity of the feed port 29, and make the semi-finished stainless steel pills fall into the grinding cavity 28 through the feed port 29, and then drive the rotating column 23 to rotate, and make the rotating column 23 drive the rotating disk 24 to rotate, and the rotating disk 24 is evenly provided with a plurality of semicircular limiting grooves 27 on the outside, and then during the rotation of the rotating disk 24, the semi-circular limiting grooves 27 are used to drive the semi-finished stainless steel pills to rotate synchronously, so that the semi-finished stainless steel pills can generate friction with the grinding sheet and the grinding sand sheet 30 during the movement, so that the semi-finished stainless steel pills can be polished and smooth during the movement, and after the semi-circular limiting grooves 27 drive the semi-finished stainless steel pills to rotate one circle, the polished semi-finished stainless steel pills will be discharged into the inner cavity of the protective shell 1 through the connecting groove 26, and then the polished stainless steel pills are driven to rotate clockwise in the inner cavity of the protective shell 1, so that the polished stainless steel pills are polished in the inner cavity of the protective shell 1;

[0047] After the semi-finished stainless steel shot is polished, the stainless steel shot will fall into the inner cavity of the protective shell 1 through the connecting groove 26, and then the stainless steel shot will be driven to rotate in the inner cavity of the protective shell 1. At the same time, when the stainless steel shot rotates to the mounting groove 19, the stainless steel shot will contact the sponge pad 18, and the polishing agent is stored in the inner cavity of the storage box 16, and the polishing agent will flow into the sponge pad 18 through the through hole 32 for storage. After the stainless steel shot contacts the sponge pad 18, the sponge pad 18 applies the polishing agent on the surface of the stainless steel shot. At the same time, as the stainless steel shot is continuously driven to rotate in the inner cavity of the protective shell 1, the stainless steel shot is polished and polished by the polishing sandpaper 31. The stainless steel shot rotates irregularly in the inner cavity of the protective shell 1, so that the surface of the entire stainless steel shot can be effectively polished, thereby improving the efficiency of the surface polishing of the stainless steel shot.

[0048] After the polishing of the stainless steel shot is completed, the discharge port 11 is opened by pulling the receiving rack 10, and then when the pushing column 21 moves the stainless steel shot to the discharge port 11, the stainless steel shot will fall into the inner cavity of the discharge port 11 and slide into the receiving rack 10, and then a collection box is placed at the outlet of the receiving rack 10 to collect the discharged stainless steel shot, thereby completing the processing and production of the stainless steel shot and improving the convenience of collecting the stainless steel shot.
