Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-precision steel ball production technology, specifically a screening device for high-precision steel ball production and processing. Background Technology
[0002] Steel balls are important basic components, especially precision industrial steel balls, which play a significant role in national economic development. For example, bearing steel balls are essential basic components in industry. Alloy steel balls are spherical iron alloy wear-resistant bodies made by forging, spinning, rolling, and casting, with carbon, chromium, manganese, molybdenum, and other main added metal elements. They are the most important components in today's crushing industry, mining, cement, and other industries. Steel balls are often used in precision industries. Due to the high requirements for their size and assembly, sorting machinery is needed to screen them after processing.
[0003] As shown in the authorization announcement number CN216965252U, a steel ball screening device includes a fixed frame, a rotating tube, a guide plate, and a screening mechanism. The fixed frame is a stainless steel rectangular frame, and a placement groove is provided on the upper part of the fixed frame. The rotating tube is installed inside the placement groove. One end of the rotating tube is connected to a ring gear, and the ring gear is connected to a first drive motor through a drive wheel. A first conveying frame is provided at one end of the rotating tube, and one end of the first conveying frame is connected to the guide plate. The discharge of the guide plate is connected to the screening mechanism. The screening mechanism includes a receiving box, a conveying trough, a discharge pipe, and a collection box. The conveying trough is fixedly installed on the upper part of the receiving box by a column, and the lower part of the conveying trough is connected to the inner cavity of the receiving box through the discharge pipe. This device is used to solve the problems of existing steel ball screening processes being not only time-consuming and labor-intensive but also having low work efficiency.
[0004] In the implementation of the above scheme, materials are fed through feeding ports of different specifications. However, since the bottom of the steel ball is arc-shaped, when the steel ball moves to the smaller feeding port, its bottom may get stuck on the top of the feeding port, which can easily cause blockage of the steel ball during the screening process, reducing the screening efficiency and screening effect of the steel ball.
[0005] Based on this, the applicant proposes a screening device for high-precision steel ball production and processing. Utility Model Content
[0006] The purpose of this invention is to address the problems of easy clogging, low screening efficiency, and poor screening effect in existing steel ball screening processes. It provides a high-precision steel ball production and processing screening device with a reasonable structural design, capable of fully agitating the steel balls, performing multi-stage screening of high-precision steel balls, reducing the risk of clogging, and achieving high screening efficiency and good screening effect.
[0007] The technical solution adopted by this utility model to solve the technical problem is as follows:
[0008] A screening device for high-precision steel ball production and processing includes a base plate and a screening box. The base plate has a vertical plate and a receiving box. A top plate is mounted on the vertical plate, and a feeding structure is located on the top plate. High-precision steel balls to be screened are poured into the feeding structure, which diverts the balls, dispersing them into the uppermost screening box. This prevents a large number of high-precision steel balls from accumulating and effectively improves the screening efficiency. One end of the screening box is mounted on the vertical plate, and the other end extends out of the vertical plate. A discharge pipe is located at the bottom of the screening box, and a feed pipe is also located at the end of the screening box extending out of the vertical plate. The discharged high-precision steel balls are discharged from the screening box through the discharge pipe, facilitating the screening of the high-precision steel balls. The steel balls are collected. High-precision steel balls that are not fully screened fall from the sieve plate to the bottom of the screening box and then through the discharge pipe into the adjacent screening box below for further screening. After being screened by multiple screening boxes, the final high-precision steel balls fall into the receiving box. The high-precision steel balls screened in each screening box are discharged from the corresponding discharge pipe, thus classifying and collecting the high-precision steel balls. This achieves the sorting process of high-precision steel balls, improving the sorting efficiency and quality. The upright plate is equipped with a toggle structure corresponding to each screening box. This toggle structure allows for sufficient agitation of the high-precision steel balls on the sieve plate within the screening box, ensuring thorough screening and improving the screening efficiency and quality.
[0009] Preferably, the feeding structure includes a feeding box, which is installed on a top plate. A feeding hopper is provided at the top of the feeding box, and a baffle is provided inside the feeding box. The baffle is designed as an arc shape. High-precision steel balls that need to be screened are poured into the feeding hopper. Gravity causes the high-precision steel balls to fall onto the baffle inside the feeding box. The high-precision steel balls bounce on the baffle, which diverts the high-precision steel balls. The diverted high-precision steel balls fall into the uppermost screening box, which avoids a large number of high-precision steel balls from gathering together and can effectively improve the screening efficiency of high-precision steel balls.
[0010] Preferably, the screening box is equipped with a sieve plate, and there are 2-5 screening boxes. The mesh size of the sieve plate in the screening box increases from top to bottom. Multiple screening boxes are arranged vertically between the vertical plates. Multiple screening boxes can perform multiple screening processes on high-precision steel balls, thereby improving the screening effect of high-precision steel balls.
[0011] Preferably, the inner wall of the screening box near the feeding pipe is provided with a slot, and a partition is vertically inserted into the slot. The partition can block the high-precision steel balls in the screening box, preventing the insufficiently screened high-precision steel balls from being discharged from the feeding pipe. This facilitates the actuation structure to fully actuate the high-precision steel balls on the screen plate in the screening box, thus performing sufficient screening and improving the screening efficiency and effect. After the high-precision steel balls are screened, the partition can be pulled out from the slot, allowing the screened high-precision steel balls on the screen plate to be quickly discharged from the feeding pipe. This allows for the classified collection of the screened high-precision steel balls, improving the feeding efficiency of the high-precision steel balls.
[0012] Preferably, a guide plate is provided at the bottom of the screening box. The guide plate is designed with a wave-shaped structure, and the discharge pipe is connected to the lowest point of the guide plate. High-precision steel balls roll back and forth on the screen plate to screen them. High-precision steel balls with a diameter smaller than the inner diameter of the screen holes fall from the screen holes on the screen plate, roll through the guide plate, and enter the discharge pipe. The guide plate can prevent high-precision steel balls from remaining in the screening box, thereby fully screening the high-precision steel balls and improving the screening efficiency and effect.
[0013] Preferably, the actuating structure includes a hydraulic cylinder and a push plate. The hydraulic cylinder is mounted on the vertical plate and has a piston rod. The push plate is connected to the piston rod, and an actuating rod is located at the bottom of the push plate, extending its bottom above the sieve plate inside the screening box. The hydraulic cylinder pushes the piston rod to move back and forth, and the push plate moves back and forth inside the screening box under the action of the piston rod. The push plate drives the actuating rod to move back and forth above the sieve plate inside the screening box, actuating the high-precision steel balls on the sieve plate, causing the high-precision steel balls to roll back and forth on the sieve plate, thus screening the high-precision steel balls and improving the screening efficiency and effect.
[0014] Beneficial effects:
[0015] 1. A baffle is installed in the feeding box, and the baffle is set as an arc structure. The high-precision steel balls that need to be screened are poured into the feeding box. Gravity causes the high-precision steel balls to fall onto the baffle in the feeding box. The high-precision steel balls bounce on the baffle and are diverted. The diverted high-precision steel balls fall into the screening box at the top, which avoids a large number of high-precision steel balls from gathering together and can effectively improve the screening efficiency of high-precision steel balls.
[0016] 2. The partition can block the high-precision steel balls in the screening box, preventing insufficiently screened high-precision steel balls from being discharged from the feed pipe. It also facilitates the agitation structure to fully agitate the high-precision steel balls on the screen plate in the screening box, thus ensuring thorough screening and improving the screening efficiency and effect. After the high-precision steel balls are screened, the partition can be pulled out from the slot to quickly discharge the screened high-precision steel balls from the feed pipe, allowing for classified collection and improving the feeding efficiency of the high-precision steel balls.
[0017] 3. The hydraulic cylinder pushes the piston rod to move back and forth. Under the action of the piston rod, the push plate moves back and forth in the screening box. The push plate drives the actuating rod to move back and forth above the screen plate in the screening box, actuating the high-precision steel balls on the screen plate, causing the high-precision steel balls to roll back and forth on the screen plate, thus screening the high-precision steel balls and improving the screening efficiency and effect.

[0025] The present invention will now be described in more detail with reference to the accompanying drawings.

A discharge pipe 12 is provided at the bottom of the screening box 2, and a discharge pipe 11 is provided at the end of the screening box 2 that extends out of the vertical plate 3. A toggle structure corresponding to the screening box 2 is provided on the vertical plate 3.
[0028] The feeding structure includes a feeding box 6, which is set on the top plate 5. A feeding hopper 7 is set on the top of the feeding box 6, and a baffle 8 is set inside the feeding box 6, with the baffle 8 being set as an arc-shaped structure.
[0029] The screening box 2 is equipped with a screen plate 9. There are 3 screening boxes 2, and the mesh size of the screen plates 9 in the screening box 2 increases from top to bottom. A slot 14 is provided on the inner wall of the end of the screening box 2 near the feed pipe 11, and a partition 10 is vertically inserted into the slot 14. A guide plate 13 is provided at the bottom of the screening box 2. The guide plate 13 is set with a wave-shaped structure, and the feed pipe 12 is connected to the lowest point of the guide plate 13.
[0030] Preferably, the actuating structure includes a hydraulic cylinder 15 and a push plate 16. The hydraulic cylinder 15 is mounted on the vertical plate 3, and a piston rod 17 is mounted on the hydraulic cylinder 15. The push plate 16 is connected to the piston rod 17, and an actuating rod 18 is mounted at the bottom of the push plate 16, extending the bottom of the actuating rod 18 above the sieve plate 9 inside the screening box 2.
[0031] Example 2:
[0032] This embodiment is a further description based on Embodiment 1, as shown in the appendix. Figure 5-6 As shown: A screening device for the production and processing of high-precision steel balls is provided with a shock-absorbing pad 19 on the top of the push plate 16. The top of the shock-absorbing pad 19 is set as an arc structure and the shock-absorbing pad 19 is made of rubber material. The high-precision steel balls screened in the upper screening box 2 fall into the lower screening box 2 through the discharge pipe 12. The shock-absorbing pad 19 can prevent the high-precision steel balls falling from the discharge pipe 12 from bouncing on the push plate 16. The high-precision steel balls falling on the shock-absorbing pad 19 roll along the surface of the shock-absorbing pad 19 into the screening box 2, preventing the high-precision steel balls from rolling out of the screening box 2 and reducing the waste of high-precision steel balls.
[0033] Working principle: Insert the partition 10 into the slot 14 on the inner wall of the screening box 2. Pour the high-precision steel balls to be screened into the feed hopper 7. Gravity causes the high-precision steel balls to fall onto the baffle 8 in the feed box 6. The high-precision steel balls bounce on the baffle 8, diverting the high-precision steel balls. The diverted high-precision steel balls fall into the uppermost screening box 2. Start the hydraulic cylinder 15. The hydraulic cylinder 15 pushes the piston rod 17 to move back and forth. The push plate 16 moves back and forth in the screening box 2 under the action of the piston rod 17. The push plate 16 drives the actuating rod 18 to move back and forth above the screen plate 9 in the screening box 2, actuating the high-precision steel balls on the screen plate 9, causing the high-precision steel balls to move on the screen plate. The screen plate 9 rolls back and forth to screen the high-precision steel balls. The high-precision steel balls with a diameter smaller than the inner diameter of the screen holes of the screen plate 9 fall from the screen holes on the screen plate 9, roll through the guide plate 13 into the discharge pipe 12, and fall from the discharge pipe 12 into the screening box 2 below for further screening. After the high-precision steel balls are screened by multiple screening boxes 2, the high-precision steel balls screened by the bottom screening box 2 fall into the receiving box 4 on the bottom plate 1. The partition plate 10 is pulled out from the slot 14 on the inner wall of the screening box 2. The high-precision steel balls screened on the screen plate 9 in the screening box 2 are discharged from the screening box 2 through the discharge pipe 11. The high-precision steel balls are classified and collected to complete the screening of high-precision steel balls.
