Description

Technical Field

[0001] The utility model relates to the technical field of tapered roller production, in particular to a tapered roller cold heading and cutting material ejection mechanism. Background Art

[0002] Tapered roller bearings feature tapered raceways on both the inner and outer rings. They are available in single-row, double-row, and four-row varieties. Due to their compact structure, strong load-bearing capacity, and separable inner and outer rings, tapered roller bearings are widely used in automotive transmissions and are also employed in industries such as rolling mills, mining, metallurgy, and plastics machinery. The production of tapered rollers requires the use of a cold heading machine, which applies a certain amount of pressure to the metal blank at room temperature, causing it to plastically deform within the die cavity and form it into the specified shape and size.

[0003] However, the existing cold heading machines lack a limiting structure that can be easily adjusted when feeding. When the size of the blank production needs to be adjusted, workers need to replace the blank fixed-length barrel, which is time-consuming and labor-intensive and will reduce work efficiency. For this reason, a tapered roller cold heading cutting and pushing mechanism is proposed. Utility Model Content

[0022] 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 embodiments described are only part of the embodiments, not all of the embodiments. Based on the embodiments, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection.

[0023] Example 1:

[0024] See also Figure 1-3 A tapered roller cold heading cutting and feeding mechanism comprises a cold heading machine 1, an operating slot is provided in the middle of the cold heading machine 1, a forming die 2 is installed on the left side of the cold heading machine 1, a stamping module 3 is installed on the right side of the cold heading machine 1, a first motor 4 is fixedly installed inside the operating slot, a swing arm 5 is fixedly installed on the output end of the first motor 4, a cutting and fixing cylinder 6 is installed on the outside of the swing arm 5, a side plate 12 is fixedly installed on the rear part of the operating slot, a compression rod 8 is slidably installed on the right surface of the cutting and fixing cylinder 6, a first spring 9 is wound around the outside of the compression rod 8, a circular plate 10 is fixedly installed on both ends of the compression rod 8, a limiting frame 7 is fixedly installed on the outside of the side plate 12, a sliding frame 13 is slidably installed on the upper surface of the side plate 12, a baffle 19 is fixedly installed on the front of the sliding frame 13, and a movable bead 20 is movably provided on the left surface of the baffle 19. A feed port 11 is provided on the surface of the forming die 2.

[0025] Specifically, the wire enters the cutting and lengthening cylinder 6 from the feed port 11, and is squeezed against the circular plate 10 when entering the cutting and lengthening cylinder 6, which then stretches the spring and adjusts the baffle 19 to a suitable position. The baffle 19 can limit the right movement of the compression rod 8, thereby limiting the length of the wire entering.

[0026] Preferably, the outer side of the rocking arm 5 is slidably connected to the inner wall of the limit frame 7, the two ends of the first spring 9 are connected to the outer side of the cutting and length cylinder 6 and the outer side of the circular plate 10 on the right, and the feed port 11 is arranged corresponding to the cutting and length cylinder 6.

[0027] Specifically, the swing arm 5 is close to the surface of the forming mold 2. When the first motor 4 drives the swing arm 5 to swing, the cutter set in the cutting length cylinder 6 will cut the end of the wire material, and then move in a circle and move accordingly to the center point of the forming mold 2.

[0028] Preferably, a limit rod 14 is slidably installed on the surface of the sliding frame 13, a pressure plate 15 is fixedly installed on the outside of the limit rod 14, a second spring 16 is wound around the outside of the limit rod 14, a limit hole 17 is opened on the upper surface of the side plate 12, and both ends of the second spring 16 are connected to the pressure plate 15 and the lower surface of the sliding frame 13.

[0029] Specifically, when the limiting rod 14 is pulled upward, the limiting rod 14 will move with the pressing plate 15 , thereby squeezing the second spring 16 , and the limiting rod 14 will leave the limiting hole 17 , thereby moving the sliding frame 13 .

[0030] Preferably, a limiting groove 18 is slidably mounted on the inner wall of the side plate 12 , and the lower outer side of the sliding frame 13 is slidably connected to the inner wall of the limiting groove 18 .

[0031] Working principle: The wire material will enter the cutting and fixed length cylinder 6 through the feed port 11. After entering the cutting and fixed length cylinder 6, the wire material will be squeezed onto the circular plate 10, causing the compression rod 8 to move outward. The compression rod 8 will stretch the first spring 9, and then the circular plate 10 at the other end of the compression rod 8 will be tightly attached to the movable bead 20. The movable bead 20 can reduce the friction of the movement of the circular plate 10. Then the first motor 4 drives the swing arm 5 to rotate, and the cutter set in the cutting and fixed length cylinder 6 will cut the wire material, and then move in a circle, and move correspondingly to the center point of the forming mold 2. After that, the stretched first spring 9 will recover, and push the cut end of the wire material into the forming mold with the compression rod 8. In the mold 2, the stamping module 3 then punches the line material in and out to form it. After pulling the limit rod 14 upward, the limit rod 14 will move the pressure plate 15 upward, and the pressure plate 15 will squeeze the second spring 16. Then the sliding frame 13 can be moved, and the sliding frame 13 will move along the side plate 12 and the limit groove 18. The sliding frame 13 will move with the baffle 19. After moving and adjusting the position, the limit rod 14 is released, and the limit rod 14 will be installed in the limit hole 17, which can limit the baffle 19, thereby achieving the purpose of conveniently adjusting the length of the feed, and producing tapered rollers of different lengths, which can effectively improve work efficiency.

[0032] Example 2:

[0033] See also Figure 1-3 A mounting plate 21 is fixedly installed on the left outer surface of the cold heading machine 1, a mounting sleeve 22 is fixedly installed on the surface of the mounting plate 21, a cleaning cylinder 23 is rotatably installed on the inner wall of the mounting sleeve 22, a first gear 24 is fixedly installed on the outer side of the cleaning cylinder 23, and a cleaning brush 25 is provided on the inner wall of the cleaning cylinder 23.

[0034] Preferably, a second motor 26 is mounted on the surface of the mounting plate 21 , a second gear 27 is fixedly mounted on the output end of the second motor 26 , the surface of the second gear 27 is rotatably connected to the surface of the mounting plate 21 , and the first gear 24 is meshed with the second gear 27 .

[0035] Working principle: When the wire material enters the feed port 11, it will first pass through the cleaning cylinder 23. At this time, the second motor 26 is started to rotate the second gear 27, and the second gear 27 will drive the first gear 24 to rotate. Then the first gear 24 will rotate with the cleaning cylinder 23, and the cleaning brush 25 in the cleaning cylinder 23 will also rotate, so that the surface of the wire material can be cleaned, thereby ensuring that the surface of the wire material is clean and preventing debris from affecting subsequent processing.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit thereof, the scope of which is defined by the appended claims and their equivalents.
