Description

Technical Field

[0001] This utility model relates to the field of cold heading technology for steel balls, and specifically to a cold heading device for steel balls. Background Technology

[0002] A cold heading machine is a type of mechanical equipment used for metal forming. It is mainly used for cold heading of steel. It can process metal with little or no heating, thus saving energy and maintaining good material properties. However, cold heading machines have drawbacks such as uneven and unreliable cutting after processing steel. They are prone to producing burrs and pad marks that embed into the surface of the steel ball, resulting in inconsistent sizes and specifications of the finished products. These defective products are usually picked out manually by workers.

[0003] Among them, Chinese patent with announcement number CN221908311U discloses a cold heading device for steel balls with sorting function. It discharges steel balls from the cold heading machine body into the sorting bin through a guide channel. The steel balls roll along the inclined surface of the sorting plate and are sorted by adapting the width of the sorting groove to the diameter of the steel balls. For different types of steel balls, the screw rod can be driven to rotate, which drives the slider to move along the side cavity, so that the adjusting plate moves along the side groove, thereby making the adjusting groove and the sorting groove staggered, changing the width of the groove, and thus adapting to the sorting needs of steel balls with different diameters.

[0004] Although the above scheme can change the width of the trough opening to sort steel balls of different diameters by staggering the adjustment trough and the sorting trough, the steel balls are easily stuck in the horizontally set sorting trough because they are rolled and screened on the sorting plate by gravity. This can lead to material jamming and affect the subsequent sorting of steel balls.

[0005] Therefore, this utility model provides a cold heading equipment for steel balls to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a cold heading equipment for steel balls, which solves the problem that steel balls are easily stuck in the horizontally set sorting troughs due to the rolling screening of steel balls on the sorting plate by gravity, thus causing material jamming and affecting the subsequent steel ball sorting.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A cold heading device for steel balls includes a cold heading machine and a feeding plate. A base plate is provided on one side of the cold heading machine, and a screening box is provided above the base plate. A fixed plate is fixedly connected inside the screening box, and sieve plates arranged at equal intervals are fixedly connected on the fixed plate. An adjusting plate matching the sieve plates is provided below the sieve plates, and a screening space is formed by adjacent sieve plates and the adjusting plate. The end of the feeding plate away from the cold heading machine is located above the screening space. A moving component is provided on the screening box for moving the adjusting plate to change the size of the screening space. A vibration component is provided on the base plate for lateral vibration of the screening box.

[0009] Preferably, each of the screening plates is fixedly connected with a baffle.

[0010] Preferably, the moving component includes an adjusting bolt rotatably connected to the screening box, a moving block threaded onto the adjusting bolt, and one end of the adjusting plate fixedly connected to the moving block.

[0011] Preferably, a guide rod is fixedly connected inside the screening box, a guide block is slidably connected to the guide rod, and the middle section of the adjusting plate is fixedly connected to the guide block.

[0012] Preferably, a guide plate is fixedly connected inside the screening box, and a first collection box and a second collection box are placed on the cold heading machine. The first collection box is located at the discharge end of the guide plate, and the second collection box is located at the discharge end of the screening plate.

[0013] Preferably, the vibration assembly includes a motor mounted on a base plate, a first bevel gear mounted on the output shaft of the motor, a drive shaft rotatably connected to the base plate, a second bevel gear and an eccentric circular plate fixedly connected to the drive shaft, the second bevel gear meshing with the first bevel gear, a linkage frame fixedly connected to the bottom surface of the screening box, and the eccentric circular plate contacting the inner wall of the linkage frame.

[0014] Preferably, two guide rails are fixedly connected to the base plate, and two rollers are installed on the bottom surface of the screening box, with the rollers located inside the guide rails.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By setting equally spaced screening plates and matching adjustment plates in the screening box, a screening channel is formed by the space between adjacent screening plates and adjustment plates. When steel balls enter the screening box from the feed plate, they will roll along the inclined screening plates and be automatically screened. Since the width of the screening space can be adjusted by moving components, the equipment can adapt to the screening needs of steel balls of different diameters, improving the accuracy and efficiency of sorting, while avoiding the problem of steel balls getting stuck in the sorting trough in traditional solutions.

[0017] 2. By setting up a vibration component, which utilizes a motor, bevel gear transmission system, and eccentric circular plate, the lateral vibration of the screening box is achieved. This helps to move the steel balls smoothly to the screening space for screening, which not only increases the automation level of the entire system, but also ensures the continuity and stability of the screening process and reduces the need for manual intervention.

[0023] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0024] A cold heading equipment for steel balls includes a cold heading machine 1 and a feeding plate 2. The cold heading machine 1 is an existing structure, which has a cold heading structure for cold heading steel bars into steel balls, and can discharge the formed steel balls by rolling through the feeding plate 2.

[0025] A base plate 3 is provided on one side of the cold heading machine 1. A screening box 4 is provided above the base plate 3. A fixed plate 5 is fixedly connected inside the screening box 4. Screening plates 6 are fixedly connected at equal intervals on the fixed plate 5. There is space between adjacent screening plates 6. An adjusting plate 10 matching the screening plate 6 is provided below the screening plate 6. The screening space is formed by the adjacent screening plates 6 and the adjusting plate 10. The end of the feeding plate 2 away from the cold heading machine 1 is located above the screening space. A baffle 7 is fixedly connected to each screening plate 6.

[0026] After the steel balls enter the screening box 4 through the feed plate 2, the steel balls will roll into the screening space for rolling screening because the screening plate 6 is designed to be inclined. The baffle 7 can prevent the steel balls from rolling on the surface of the screening plate 6. Unqualified steel balls will fall from the screening space, while qualified steel balls will roll out of the screening space, thus completing the screening of steel balls.

[0027] The screening box 4 is equipped with a moving component for moving the adjusting plate 10 to change the size of the screening space. The moving component includes an adjusting bolt 8 rotatably connected to the screening box 4, a moving block 9 threadedly connected to the adjusting bolt 8, and one end of the adjusting plate 10 fixedly connected to the moving block 9.

[0028] By rotating the adjusting bolt 8, the moving block 9 can move on the adjusting bolt 8, thereby causing the moving block 9 to drive multiple adjusting plates 10 to move synchronously, thus completing the synchronous adjustment of multiple screening spaces.

[0029] In this embodiment, a guide rod 11 is fixedly connected inside the screening box 4, and a guide block 12 is slidably connected on the guide rod 11. The middle section of the adjusting plate 10 is fixedly connected to the guide block 12. When the adjusting plate 10 moves, it will drive the guide block 12 to slide on the guide rod 11, ensuring the stability of the movement of the adjusting plate 10 and improving the load-bearing capacity of the adjusting plate 10.

[0030] The screening box 4 is fixedly connected with a guide plate 13. The cold heading machine 1 is equipped with a first collection box 14 and a second collection box 15. The first collection box 14 is located at the discharge end of the guide plate 13, and the second collection box 15 is located at the discharge end of the screening plate 6. The steel balls that fall on the guide plate 13 will be collected in the first collection box 14, while the steel balls that roll out in the screening space will fall into the second collection box 15 for collection.

[0031] In this embodiment, a vibration assembly for transverse vibration of the screening box 4 is provided on the base plate 3. The vibration assembly includes a motor 18 mounted on the base plate 3. A first bevel gear 19 is mounted on the output shaft of the motor 18. A drive shaft 20 is rotatably connected to the base plate 3. A second bevel gear 21 and an eccentric circular plate 22 are fixedly connected to the drive shaft 20. The second bevel gear 21 meshes with the first bevel gear 19. A linkage frame 23 is fixedly connected to the bottom surface of the screening box 4. The eccentric circular plate 22 is in contact with the inner wall of the linkage frame 23.

[0032] The output shaft of motor 18 drives the first bevel gear 19 to rotate, and under the action of the second bevel gear 21, it drives the drive shaft 20 to rotate synchronously. This causes the drive shaft 20 to drive the eccentric circular plate 22 to rotate within the linkage frame 23, thereby pushing the linkage frame 23 to move back and forth in the lateral direction, which in turn causes the screening box 4 to oscillate laterally, moving the steel balls to the screening space for screening.

[0033] Two guide rails 16 are fixedly connected to the base plate 3, and two rollers 17 are installed on the bottom surface of the screening box 4. The rollers 17 are located inside the guide rails 16. When the screening box 4 moves back and forth, it can drive the rollers 17 to roll inside the guide rails 16, thus providing auxiliary support for the screening box 4.
