Description

Technical Field

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

[0002] Steel balls are often used in bearings, ball mills, or other equipment used for transmission and connection due to their good hardness, wear resistance, and low friction brought by their spherical structure. The production process includes raw material preparation, blank cutting, steel ball forming, and subsequent processing. Therefore, it is necessary to use transmission and unloading equipment to move the steel balls to different processing areas. For unloading distances with large height differences, spiral unloading barrels are usually used for dropping.

[0003] During the falling process, the steel ball embryo will rotate and fall inside the spiral discharge barrel, which can effectively reduce the discharge speed of the discharge port, thereby reducing the generated kinetic energy and indirectly protecting the steel ball. However, during the falling process, the speed of the steel ball is still increasing, so it still generates a lot of kinetic energy.

[0004] Moreover, for steel balls with larger mass, the unloading time is shorter, but the larger the mass of the steel ball, the greater the kinetic energy generated, and the greater the impact on the steel ball itself. Similarly, for steel balls with smaller mass, although smaller kinetic energy can be guaranteed to achieve protection of the steel ball, the overall unloading time is longer, which affects the unloading rate of the steel ball. The existing spiral unloading barrel is difficult to adjust the unloading for steel balls of different mass. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

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

[0035] like Figure 1-Figure 2 As shown, an automatic unloading device for steel ball production includes a plurality of tilted and rotatable ball guide plates 1, the shape of the ball guide plates 1 can be set to have a straight or arc-shaped cross-section, and the plurality of ball guide plates 1 are installed inside a unloading box 2, a feed port is set at a corresponding position on the top of the unloading box 2, and a discharge port is set at a corresponding position on the bottom, and the plurality of ball guide plates 1 are installed in a longitudinal array inside the unloading box 2, with two adjacent ball guide plates 1 forming a group from top to bottom, and the two ball guide plates 1 in the same group are installed horizontally symmetrically but at different heights. It should be noted that the projections of the two ball guide plates 1 in the same group in the vertical direction partially overlap, and the position of the end of the two ball guide plates 1 in the same group close to the symmetry line is higher than the end away from the symmetry line.

[0036] The steel ball enters from the feed port of the discharge box 2 and falls onto the ball guide plate 1 at the top position. At this time, the steel ball will move toward the lower side due to the tilt direction of the ball guide plate 1. When it reaches the critical point, the ball guide plate 1 rotates in the opposite direction of the tilt. The steel ball will still move due to its own gravity until it falls on the ball guide plate 1 below, and thus gradually falls and transfers to realize the discharge process until it falls on the last ball guide plate 1. The speed at which the steel ball falls to the discharge port is determined by the height between the critical point on the ball guide plate 1 at that position and the discharge port. Compared with the spiral discharge barrel, the discharge speed of the steel ball from the discharge port position is determined by the entire height difference of the spiral discharge barrel. Therefore, for steel balls of the same mass, the kinetic energy generated by this embodiment is smaller, and the damage to the steel ball itself is smaller.

[0037] Since kinetic energy is determined by mass and speed, it should be noted that the rotation angle of the ball guide plate 1 is different for steel balls of different masses. The angle is controlled by setting an adjustment component. The rotation angle of steel balls with larger mass needs to be smaller, reducing the height difference to slow down their falling speed and control the kinetic energy generated by their falling. In order to ensure the efficiency of the entire unloading, multiple unloading boxes 2 need to be set up, and the rotation angle of steel balls with smaller mass needs to be increased, increasing the height difference to increase the falling speed, ensuring that the kinetic energy is within a reasonable range, but can increase the falling speed of the steel balls, thereby ensuring the efficiency of the entire unloading.

[0038] This application proposes two different embodiments for the adjustment component:

[0039] Example 1

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

[0041] When the steel ball falls on the falling area of ​​the ball guide plate 1, it rolls to the unlocking position of the locking assembly due to its own gravity. The unlocking position is the critical area. For steel balls of different masses, spring seats 5 with different elastic coefficients need to be replaced. The larger the mass, the larger the elastic coefficient of the spring seat 5 required. 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 mass of the steel balls in the same batch is 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 assembly 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 ball is located between the two ball guide plates 1, causing the steel ball to be stuck in this position and difficult to fall.

[0043] like Figure 3-Figure 4 The locking assembly includes a mounting groove 8 and a guide groove 9 opened along the inclined direction of the ball guide plate 1. The mounting groove 8 is opened on the surface of the positioning shaft 4, and a card rod 11 is assembled inside through an installation spring 10. A part of the card rod 11 is located inside the mounting groove 8. When the installation spring 10 is compressed, the card rod 11 can be completely compressed to the inside of the mounting groove 8. One end of the card rod 11 extends to the inside of the guide groove 9. The guide 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 mounting groove 8 is connected to the outside through the guide groove 9. When the steel ball moves and hits the moving rod 12, it will indirectly push the card rod 11 to move until it is located inside the mounting groove 8.

[0044] The end of the card rod 11 located inside the guide groove 9 is set to an arc surface that matches the surface of the positioning shaft 4, and the end of the moving rod 12 that contacts the card rod 11 is set to adapt to the end of the card rod 11. The movable distance of the moving rod 12 is the length of the card rod 11 protruding from the mounting groove 8, that is, when the moving rod 12 squeezes the card 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 detaches from the ball guide plate 1, and the spring seat 5 pulls the ball guide plate 1 to its initial state. The installation spring 10 will also squeeze the card rod 11 back to its initial state until the next repeat of the above 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 direction of the mounting groove 8 and the guide groove 9 in this embodiment is 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 through 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. 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 state.

[0048] Example 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 state of the unloading device. Figure 13 This is a schematic diagram of the continuous unloading state of the unloading device.

[0050] like Figure 8 、 Figure 10-12 As shown, movable extension plates 17 are assembled at both ends of the ball guide plate 1, and a rotatable circular shaft 18 is installed at the right end of the extension plate 17 on the right side, and a slide groove 19 is provided on the right inner side of the discharge box 2. The circular shaft 18 is stuck in the inner side of the slide groove 19 and moves to ensure that when the ball guide plate 1 rotates, the extension plate 17 will be positioned by the slide groove 19, so that it will be relatively stretched. The right extension plate 17 is located above the ball guide plate 1, and the left extension plate 17 is located below the ball guide plate 1. To ensure the normal movement of the extension plate 17, a transverse groove 29 is provided on the lower surface of the extension plate 17 on the right side of the ball guide plate 1 and the left lower surface of the ball guide plate 1. The surfaces of the left extension plate 17 and the ball guide plate 1 are installed with guide blocks 20 that are adapted to the shape of the transverse groove 29. The cross-sections of the guide block 20 and the transverse groove 29 are both T-shaped.

[0051] An integrally formed fixed plate 21 is provided on the ball guide plate 1, and an integrally formed movable plate 23 is provided on the left extension plate 17. A connecting spring 24 is provided between the movable plate 23 and the fixed plate 21. A guide rod 22 for guiding is installed on the surface of the fixed plate 21. The guide rod 22 is movable through the movable plate 23 to prevent the connecting spring 24 from bending. A round rod 25 is assembled on the surface of the movable plate 23. The length of the round rod 25 needs to be greater than the width of the extension plate 17 and the ball guide plate 1. A fan-shaped guide plate 26 is installed inside the discharge box 2, and the round rod 25 is against the surface of the guide plate 26. The guide plate 26 is located on the side of the extension plate 17 and the ball guide plate 1 to prevent the guide plate 26 from affecting the movement of the ball guide plate 1 and the extension plate 17 during rotation.

[0052] In this embodiment, both ends of the positioning shaft 4 need to extend to the outside of the material box 2. An integrally formed extension rod 15 with a non-circular cross-section is provided at one end of the positioning shaft 4. A card slot 16 that matches the shape of the extension rod 15 is provided at the other end of the positioning shaft 4. When multiple material boxes 2 are operated simultaneously, the corresponding extension rod 15 can be clamped inside the card slot 16, and the same motor is used for external drive to control the rotation angle of the ball guide plate 1 (refer to the state after rotation). Figure 13 and Figure 14 ), the length of the extension plate 17 on the left side that is extended by rotation depends on the diameter of the guide plate 26.

[0053] like Figure 8 and Figure 9 As shown, the guide plates 26 of the same axial direction are set as a group, and the surface of the blanking box 2 is provided with a mounting hole 27. The guide plates 26 can pass through the interior of the mounting hole 27. The two ends of the same group of guide plates 26 are equipped with mounting plates 28. The mounting plates 28 are assembled inside the mounting holes 27. Therefore, when the guide plates 26 need to be replaced for steel balls of different masses, the spring seat 5 that needs to be replaced in the first embodiment (see Figure 2 ), the replacement method will be simpler, and the angle of rotation of the ball guide plate 1 controlled by the motor will be more convenient and accurate.

[0054] During the working process of this embodiment, the steel ball falls on the top ball guide plate 1. At this time, the motor controls the ball guide plate 1 to rotate, the chute 19 pulls the extension plate 17, and 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 When in working state, the steel ball will roll on the surface of the ball guide plate 1 and the extension plate 17 due to gravity until it falls to the lowest point. At this time, it is necessary to use the motor to control the ball guide plate 1 to rotate slightly, and the connecting spring 24 rebounds to pull the extension plate 17, so that the round rod 25 rests on the surface of the guide plate 26. At this time, the extension plate 17 will not rest on the extension plate 17 below. There is a gap between adjacent extension plates 17 at the same vertical position, ensuring that the steel ball can fall from top to bottom in a broken line.

[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 next ball guide plate 1 is more stable and smooth, it is necessary to ensure that the end of the upper extension plate 17 is against the surface of the lower extension plate 17, thereby avoiding the steel ball from directly falling freely and reducing damage to the steel ball.
