Technical Field

[0001] The utility model relates to the technical field of steel ball lifting, in particular to a lifting device for conveying steel balls. Background Art

[0002] During the steel ball processing process, the steel ball blank needs to be roughly forged, and the steel ball after rough forging is then rolled to the fine electro-hydraulic hammer for fine forging. The existing steel balls are transported to the fine electro-hydraulic hammer through a conveyor track after rough forging. After that, the on-site workers use clamps to clamp the steel balls into the lower die of the fine electro-hydraulic hammer. Due to the large clamping height and large steel ball output, when the workers clamp the steel balls one by one, the workers' labor is large, the work intensity is high, and the temperature of the steel balls themselves is high, which poses a safety hazard during clamping.

[0003] The prior art patent publication number is CN220092912U, and its name is a lifting device for conveying steel balls during forging. The above patent sets this lifting device between the steel ball conveying track and the forging machine. During the forging process, the steel balls are directly conveyed to the lower die of the forging machine, eliminating the need for manual operation, reducing the workload and physical exertion of workers. It is also simple to operate, convenient to process, and has a low production cost.

[0004] In addition, the above patent sets an elastic material stop between the discharge end of the steel ball conveying track and the feed end of the supporting part, and uses the elastic material stop to control the on and off of the steel ball conveying between the steel ball conveying track and the supporting part. However, the steel ball conveying track is generally set at an angle, and when the steel ball rolls on it, the rolling speed is often fast, which will generate a large impact force on the material stop plate in the elastic stop. In the long run, it will cause the material stop plate to bend and deform, which will seriously affect the use effect of the material stop plate. Utility Model Content

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0022] Reference Figure 1-3As shown, a lifting device for conveying steel balls comprises a base 1, a steel ball conveying track 2 obliquely arranged on one side above the base 1, a material guide track 11 obliquely arranged on the other side above the base 1, and a support frame 10 fixed between the material guide track 11 and the base 1, there is a height difference between the discharge end of the material guide track 11 and the feed end of the steel ball conveying track 2, and a material loading plate 6 is slidably arranged between the steel ball conveying track 2 and the support frame 10, the top surface of the material loading plate 6 is provided with an obliquely arranged guide groove, one side of the material loading plate 6 is in contact with the surface of the support frame 10, and the other side of the material loading plate 6 is clamped with an L-shaped material blocking plate 3, and a spring telescopic rod 4 is installed between the bottom surface of the material blocking plate 3 and the base 1;

[0023] A driving frame 5 fixedly connected to the top surface of the base 1 is vertically provided on the side of the loading plate 6. A nut seat 7 fixedly connected to the side wall of the loading plate 6 is slidably provided between the inner walls on both sides of the driving frame 5. A first motor 9 is installed on the top of the driving frame 5. A screw rod 8 is threaded through the middle part of the nut seat 7. The top end of the screw rod 8 rotates out of the driving frame 5 and is fixedly connected to the output end of the first motor 9.

[0024] When the steel ball is rolled and transported by the steel ball conveyor track 2, the steel ball is pre-blocked by the material blocking plate 3 when it rolls to the discharge end position of the steel ball conveyor track 2. Then the first motor 9 is turned on, and the output shaft of the first motor 9 drives the screw rod 8 to rotate, so that the nut seat 7 carries the material carrying plate 6 down under the threaded structure, and then the material carrying plate 6 squeezes the material blocking plate 3 during the downward movement, so that the material blocking plate 3 automatically moves downward under pressure and compresses the spring telescopic rod 4 until the material blocking plate 3 releases the resistance effect on the steel ball, and the steel ball can further roll onto the material carrying plate 6;

[0025] Subsequently, the output shaft of the first motor 9 is reversed, causing the carrier plate 6 to return and move upward with the steel ball, until the carrier plate 6 moves to a position corresponding to the guide track 11. The steel ball then rolls further onto the guide track 11 and is automatically loaded into the lower die of the forging machine by the guide track 11.

[0026] During the upward movement of the loading plate 6, the pressure on the baffle plate 3 is reduced, and then the baffle plate 3 is quickly reset under the elastic force of the spring telescopic rod 4, and its vertical plate blocks the discharge end of the base 1, which can once again block the steel balls and control the on and off of the steel ball transportation between the base 1 and the loading plate 6.

[0027] However, the base 1 is arranged obliquely, and when the steel ball rolls on it, it often rolls at a high speed, which will form a large impact force on the baffle plate 3. In the long run, it will cause the baffle plate 3 to bend and deform, seriously affecting the use effect of the baffle plate 3;

[0028] For this purpose, refer to Figure 1-3As shown, it is worth noting that it also includes a deceleration mechanism provided on the discharge end of the steel ball conveying track 2 for controlling the rolling speed of the steel balls on the steel ball conveying track 2;

[0029] The deceleration mechanism includes a sponge plate 12 detachably arranged on the inner wall of the bottom end of the steel ball conveying track 2 and an intermittent magnetic attraction component arranged below the steel ball conveying track 2;

[0030] By setting the deceleration mechanism, when the steel ball is rolled and transported by the steel ball conveying track 2 to the discharge end position, the steel ball rolls on the surface of the sponge board 12, and the intermittent magnetic attraction component can intermittently form a downward magnetic attraction on the steel ball from this section, thereby increasing the contact between the steel ball and the surface of the sponge board 12, thereby utilizing the sponge board 12 to frictionally decelerate the steel ball, thereby reducing the impact force of the steel ball on the spring telescopic rod 4.

[0031] Further, refer to Figure 3 As shown, it is worth noting that the intermittent magnetic attraction component includes a mounting plate 13 arranged below the discharge end of the steel ball conveying track 2 and a movable plate 15 slidably arranged between the mounting plate 13 and the steel ball conveying track 2, a magnet 16 is installed on the top surface of the movable plate 15, an extrusion assembly is provided between the movable plate 15 and the mounting plate 13, and support rods 14 are passed through the four corners of the movable plate 15, and the two ends of the support rod 14 are fixedly connected to the steel ball conveying track 2 and the mounting plate 13 respectively. A return spring 18 is sleeved on the rod body of the support rod 14 located between the movable plate 15 and the mounting plate 13, and the two ends of the return spring 18 are fixedly connected to the movable plate 15 and the mounting plate 13 respectively;

[0032] The extrusion assembly includes two support rod plates 21 symmetrically mounted on the top surface of the mounting plate 13 and a drive rod 19 that is laterally rotatably arranged between the two support rod plates 21. The middle portion of the drive rod 19 is tightly sleeved with a cam 20 that abuts against the bottom surface of the movable plate 15.

[0033] The extrusion assembly further includes a second motor 22 mounted on the top surface of the mounting plate 13 , and a transmission belt 23 is connected between the output shaft of the second motor 22 and one end of the drive rod 19 ;

[0034] When the steel ball is rolled and transported on the base 1, the second motor 22 is turned on, and the output shaft of the second motor 22 is driven by the transmission belt 23 to drive the driving rod 19, so that the cam 20 rotates continuously and intermittently squeezes the bottom end of the movable plate 15. During this period, when the cam 20 squeezes the movable plate 15, the movable plate 15 is forced to carry the magnet 16 and slide along the rod of the support rod 14 and stretch the reset spring 18 to deform, so that the magnet 16 approaches the bottom surface of the steel ball conveying track 2. When the steel ball rolls to the surface of the sponge board 12, a downward magnetic force is formed on the steel ball, and then the sponge board 12 is used to frictionally decelerate the steel ball;

[0035] On the contrary, when the cam 20 rotates to reduce the pressure on the movable plate 15, the movable plate 15 can quickly return to the original position and slide down with the magnet 16 under the elastic force of the return spring 18, so that the cam 20 is away from the steel ball conveying track 2, reducing the magnetic attraction force on the steel balls, so as to prevent the steel balls from being over-cooled on the sponge plate 12 and unable to roll from the base 1 to the material loading plate 6.

[0036] When the steel ball is attracted by the magnet 16, it tends to roll on the sponge board 12 under pressure. Over time, an indentation is inevitably formed on the sponge board 12, causing the physical properties of the sponge board 12 to change, thereby affecting the service life of the sponge board 12 and the friction deceleration effect.

[0037] For this purpose, refer to Figure 2 As shown, it is worth noting that a groove is provided on the inner wall of the bottom end of the discharge end of the steel ball conveying track 2, which is adapted to the sponge board 12. Locking screws 17 are passed through the four corners of the sponge board 12, and a threaded hole is provided on the inner wall of the bottom end of the groove to adapt to the locking screws 17.

[0038] By setting the locking screws 17, when the steel ball rolls on the sponge board 12 under pressure for a long time, causing indentations to appear on the sponge board 12, the locking screws 17 at the four corners of the sponge board 12 can be loosened manually in turn, so that the locking screws 17 exit the corresponding threaded holes under the threaded structure, thereby facilitating the removal and replacement of the sponge board 12.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention.
