Description

Technical Field

[0001] The present invention relates to the technical field of steel ball blanking devices, and specifically provides an automatic steel ball production blanking device. Background Art

[0002] Due to its good hardness, wear resistance, and low friction brought by the spherical structure, steel balls are often used in bearings, ball mills, or other equipment for transmission and connection. Its production process includes raw material preparation, blank cutting, steel ball forming, and subsequent processing. Therefore, it is necessary to move the steel balls to different processing areas through a transmission and blanking device. For a large height difference in the blanking distance, a spiral blanking barrel is usually used for falling.

[0003] During the falling process of the steel ball blanks, they will rotate and fall inside the spiral blanking barrel, which can effectively reduce the discharging speed at the discharging port, thereby reducing the generated kinetic energy and indirectly protecting the steel balls. However, during the falling process of the steel balls, the speed is still constantly increasing, so a large amount of kinetic energy will still be generated.

[0004] Moreover, for steel balls with a larger mass, the blanking time is shorter, but the larger the mass of the steel ball, the greater the generated kinetic energy and the greater the impact on the steel ball itself. Similarly, for steel balls with a smaller mass, although a smaller kinetic energy can be ensured to protect the steel balls, the overall blanking time is longer, affecting the blanking rate of the steel balls. The existing spiral blanking barrel is difficult to adjust the blanking for steel balls of different masses. Summary of the Invention

[0010] Preferably, the positioning shaft is fixedly assembled on the surface of the ball guide plate. One end of the positioning shaft is provided with an integrally formed non-circular extension rod. A clamping groove matching the shape of the extension rod is opened at the other end of the positioning shaft. The positioning shaft is driven to rotate by an external power.

The speed at which the steel balls fall to the discharge port is determined by the height between the critical point on the lowest-positioned ball guide plate and the discharge port. Compared with the spiral blanking barrel, the height difference is smaller, so the production kinetic energy is also smaller. And for steel balls with a larger mass, a smaller rotation angle is required to reduce the height drop and thus slow down their falling speed, control the kinetic energy generated by their falling, and a plurality of blanking boxes are provided to balance the blanking efficiency. For steel balls with a smaller mass, the rotation angle needs to be adjusted larger to increase the height drop and improve the falling speed, ensuring that the kinetic energy is within a reasonable range, but being able to increase the falling speed of the steel balls, thereby ensuring the overall blanking efficiency.

Detailed implementation manners

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] As Figure 1 - Figure 2 shown, an automatic blanking device for steel ball production includes a plurality of rotatable guide ball plates 1 arranged obliquely. The shape of the guide ball plate 1 can be set to be linear or arc-shaped in cross-section. A plurality of guide ball plates 1 are installed inside the blanking box 2. A feed port is provided at the corresponding position at the top of the blanking box 2, and a discharge port is provided at the corresponding position at the bottom. The plurality of guide ball plates 1 are longitudinally arrayed and installed inside the blanking box 2. Taking two adjacent guide ball plates 1 as a group from top to bottom, the two guide ball plates 1 in the same group are horizontally symmetrically installed, but their height positions are different. It should be noted that the projections of the two guide ball plates 1 in the same group overlap partially in the vertical direction, and the position of one end of the two guide ball plates 1 in the same group close to the symmetry line is higher than the end far from the symmetry line.

[0036] The steel balls enter from the feed port of the blanking box 2 and fall onto the guide ball plate 1 at the topmost position. At this time, the steel balls will move towards the lower side due to the inclination direction of the guide ball plate 1. When reaching the critical point position, the guide ball plate 1 rotates in the opposite direction of the inclination. The steel balls will still move due to their own gravity until they fall onto the lower guide ball plate 1, and thus gradually fall and be transferred to achieve the blanking process until they fall onto the last guide ball plate 1. The falling speed of the steel balls to the discharge port is determined by the height between the critical point on the guide ball plate 1 at this position and the discharge port. In contrast, in the spiral blanking barrel, the discharge speed of the steel balls from the discharge port position is determined by the entire height difference of the spiral blanking barrel. Therefore, for steel balls of the same mass, the kinetic energy generated in this embodiment is smaller, and the damage to the steel balls themselves is smaller.

[0037] Since kinetic energy is jointly determined by mass and speed, it should be noted that for steel balls of different masses, the rotation angle of the guide ball plate 1 is different. The angle is controlled by setting an adjustment component. The rotation angle of the steel balls with a larger mass needs to be smaller to reduce the height drop and thus slow down their falling speed and control the kinetic energy generated during their fall. To ensure the efficiency of the entire blanking process, a plurality of blanking boxes 2 need to be set. The rotation angle of the steel balls with a smaller mass needs to be adjusted larger to increase the height drop and increase the falling speed to ensure that the kinetic energy is within a reasonable range, but it can increase the falling speed of the steel balls, thereby ensuring the efficiency of the entire blanking process.

[0038] Two different embodiments are proposed for the adjustment component in this application:

[0039] Embodiment 1

[0040] As shown in Figure 2 - Figure 3 , inside the blanking box 2, there are multiple protruding installation platforms. A replaceable spring seat 5 is assembled on the installation platform. The spring seat 5 is fixed by means of snap connection or threaded connection. The ball guide plate 1 includes a falling area and an assembly area for steel balls. A positioning shaft 4 is installed in the assembly area, and the positioning shaft 4 is fixed on the inner wall of the blanking box 2. The ball guide plate 1 can rotate around the positioning shaft 4. The falling area and the assembly area are respectively located on both sides of the positioning shaft 4. A guide rail 6 is provided in the assembly area of the ball guide plate 1. A rotatable slider 7 adapted to the guide rail 6 is installed on the surface of the spring seat 5. A guiding component can also be installed on the spring seat 5 to prevent the spring on the spring seat 5 from bending. A locking component is installed on the ball guide plate 1 to fix the inclination angle of the ball guide plate 1.

[0041] When the steel balls fall on the falling area of the ball guide plate 1, they roll down to the unlocking position of the locking component due to their own gravity. This unlocking position is the critical area. For steel balls of different masses, spring seats 5 with different elastic coefficients need to be replaced. The greater the mass, the greater the elastic coefficient of the required spring seat 5. Therefore, an operation window 3 needs to be opened on the surface of the blanking box 2 to facilitate the replacement of the spring seat 5. Since the masses of the steel balls in the same batch are the same, the spring seat 5 only needs to be replaced when the entire production line changes to produce steel balls of different masses.

[0042] The main purpose of the locking component is to prevent the adjacent high-position ball guide plate 1 from rotating and squeezing the low-position ball guide plate 1, so that the steel balls are in the position between the two ball guide plates 1, resulting in the situation that the steel balls are stuck in this position and difficult to fall.

[0043] As shown in Figure 3 - Figure 4 , the locking component includes an installation groove 8 and a guiding groove 9 opened along the inclination direction of the ball guide plate 1. The installation groove 8 is opened on the surface of the positioning shaft 4, and a clamping rod 11 is assembled inside through an installation spring 10. A part of the clamping rod 11 is located inside the installation groove 8. When the installation spring 10 is compressed, the clamping rod 11 can be completely compressed into the installation groove 8. One end of the clamping rod 11 extends into the guiding groove 9. The guiding groove 9 is opened on the surface of the ball guide plate 1, and an inverted L-shaped moving rod 12 is assembled inside. The installation groove 8 communicates with the outside through the guiding groove 9. When the steel balls move and impact the moving rod 12, the clamping rod 11 will be indirectly pushed to move until it is located inside the installation groove 8.

[0044] The end of the clamping rod 11 located inside the guide groove 9 is set to an arc surface matching the surface of the positioning shaft 4, and the end of the moving rod 12 in contact with the clamping rod 11 is set to adapt to the end of the clamping rod 11. The movable distance of the moving rod 12 is the length of the clamping rod 11 protruding from the mounting groove 8, that is, when the moving rod 12 squeezes the clamping rod 11 to move, the edge of the moving rod 12 just fits with the surface of the positioning shaft 4, and the moving rod 12 will not affect the rotation of the ball guide plate 1. It should be noted that when the locking assembly is unlocked, the gravity of the steel ball will cause the ball guide plate 1 to rotate until the steel ball is separated from the ball guide plate 1, and the spring seat 5 pulls the ball guide plate 1 to the initial state, and the installation spring 10 will also squeeze the clamping rod 11 back to the initial state until the next repeat of the above-mentioned stroke.

[0045] Figure 5 - Figure 7 Another embodiment is disclosed for the locking assembly.

[0046] Since a certain impact is required to make the moving rod 12 move during the unlocking process, the steel ball will still be damaged to a certain extent during the process. Therefore, the directions of the mounting groove 8 and the guide groove 9 in this embodiment are set to be perpendicular to the inclination direction of the ball guide plate 1, and the direction is set vertically upward. The corresponding moving rod 12 is set to an inverted U shape, and an anti-slip and guide component can be set on the moving rod 12 to ensure that the moving direction of the moving rod 12 is perpendicular to the inclination direction of the ball guide plate 1. In addition, it is necessary to set an extrusion plate 13 with an inclination less than that of the ball guide plate 1 on the ball guide plate 1, and install rollers 14 on the lower surface of the extrusion plate 13. The number of rollers 14 can be changed according to actual needs. The wheels of the rollers 14 are against the inside of the ball guide plate 1, and one end of the extrusion plate 13 is rotatably installed on one end of the moving rod 12.

[0047] When the steel ball falls onto the ball guide plate 1, it rolls due to its own gravity until it is located on the extrusion plate 13 and continues to roll on the extrusion plate 13. When it rolls to the critical area, the steel ball's own gravity will pull the end of the extrusion plate 13 downward, thereby unlocking the locking assembly. This process does not require unlocking by impact, thereby protecting the steel ball. Similarly, after unlocking, the ball guide plate 1 rotates to the opposite direction of the tilt until the steel ball leaves the ball guide plate 1 at this height, and the spring seat 5 and the mounting spring 10 will pull the ball guide plate 1 and the extrusion plate 13 back to their initial states.

[0048] Embodiment 2

[0049] like Figure 8 , Figure 10 and Figure 13 As shown, in this embodiment, the positioning shaft 4 is located at the center of the ball guide plate 1. Figure 10 This is a schematic diagram of the unloading device in the unloading state. Figure 13 This is a schematic diagram of the continuous unloading state of the unloading device.

[0050] like Figure 8 ,Figure 10 - Figure 12 As shown, movable extension plates 17 are assembled at both ends of the ball guiding plate 1. A rotatable round shaft 18 is installed at the right end of the extension plate 17 on the right side. A sliding groove 19 is formed on the inner right side of the blanking box 2. The round shaft 18 is stuck inside the sliding groove 19 and moves, ensuring that when the ball guiding plate 1 rotates, the extension plate 17 will be positioned by the sliding groove 19, and thus will be relatively elongated. The extension plate 17 on the right side is located above the ball guiding plate 1, and the extension plate 17 on the left side is located below the ball guiding plate 1. To ensure the normal movement of the extension plate 17, horizontal grooves 29 are formed on the lower surface of the extension plate 17 on the right side of the ball guiding plate 1 and the lower left surface of the ball guiding plate 1. Guide blocks 20 adapted to the shape of the horizontal grooves 29 are installed on the surfaces of the extension plate 17 on the left side and the ball guiding plate 1. The cross-sections of the guide blocks 20 and the horizontal grooves 29 are both T-shaped.

[0051] A fixed plate 21 is integrally formed on the ball guiding plate 1. A moving plate 23 is integrally formed on the extension plate 17 on the left side. A connecting spring 24 is arranged between the moving plate 23 and the fixed plate 21. A guiding rod 22 for guiding is installed on the surface of the fixed plate 21. The guiding rod 22 movably penetrates the moving plate 23 to prevent the connecting spring 24 from being bent. A round rod 25 is assembled on the surface of the moving plate 23. The length of the round rod 25 needs to be greater than the widths of the extension plate 17 and the ball guiding plate 1. A fan-shaped guiding plate 26 is installed inside the blanking box 2. The round rod 25 abuts against the surface of the guiding plate 26. The guiding plate 26 is located at the side position of the extension plate 17 and the ball guiding plate 1 to prevent the guiding plate 26 from affecting the movement of the ball guiding plate 1 and the extension plate 17 during the rotation process.

[0052] In this embodiment, both ends of the positioning shaft 4 need to extend to the outside of the blanking box 2. An extension rod 15 with a non-circular cross-section is integrally formed at one end of the positioning shaft 4. A clamping groove 16 adapted to the shape of the extension rod 15 is formed at the other end of the positioning shaft 4. When multiple blanking boxes 2 operate simultaneously, the corresponding extension rods 15 can be stuck inside the clamping grooves 16, and an external drive is carried out by using the same motor to control the rotation angle of the ball guiding plate 1 (for the state after rotation, refer to Figure 13 and Figure 14 ), and the extended length of the rotation of the extension plate 17 on the left side depends on the diameter of the guiding plate 26.

[0053] As Figure 8 and Figure 9 shown, the guiding plates 26 in the same axial direction are set as a group. Installation holes 27 are formed on the surface of the blanking box 2. The guiding plates 26 can pass through the inside of the installation holes 27. Installation plates 28 are assembled at both ends of the same group of guiding plates 26. The installation plates 28 are assembled inside the installation holes 27. Therefore, when the guiding plates 26 need to be replaced for steel balls of different masses, compared with the spring seat 5 that needs to be replaced in the first embodiment (refer to Figure 2 ), the replacement method is simpler, and it is more convenient and accurate to control the rotation angle of the ball guiding plate 1 by the motor.

[0054] During the working process of this embodiment, the steel ball lands on the topmost ball guide plate 1. At this time, the motor controls the rotation of the ball guide plate 1, the sliding groove 19 pulls the extension plate 17, and at the same time, the guide plate 26 squeezes the round rod 25, and the connecting spring 24 is stretched until the ball guide plate 1 rotates to Figure 13 the working state where the steel ball will roll on the surfaces of the ball guide plate 1 and the extension plate 17 due to gravity until it reaches the lowest point. At this time, it is necessary to use the motor to control the ball guide plate 1 to slightly rotate back, and the connecting spring 24 rebounds to pull the extension plate 17, so that the round rod 25 abuts against the surface of the guide plate 26. At this time, the extension plate 17 will not abut against the lower extension plate 17, and there is a gap between adjacent extension plates 17 at the same vertical position to ensure that the steel ball can fall in a zigzag shape from top to bottom.

[0055] In this application, in order to ensure that the process of the steel ball moving from the upper ball guide plate 1 to the lower ball guide plate 1 is more stable and smooth, it is necessary to ensure that the end of the upper extension plate 17 abuts against the surface of the lower extension plate 17, so as to avoid the direct free-fall phenomenon of the steel ball and reduce the damage to the steel ball.
