Description

Technical Field

[0001] This utility model relates to the technical field of toothed bar production equipment, and in particular to a toothed bar wire output machine. Background Technology

[0002] A thread rolling mill is a specialized device that uses rolling wheels to cold roll metal bars, causing plastic deformation on the surface of the bar to form threads. Its working principle is to use two rolling wheels rotating in opposite directions to extrude the blank through relative feed motion, and roll threads that meet the specifications on the surface of the blank.

[0003] In actual processing, especially when dealing with extra-long threaded rods, some equipment does not have a production line connected to the feed or discharge point. The processed threaded rods can only fall directly into the collection basket. Extra-long threaded rods are long, and without necessary support, they are prone to slight falling due to their own weight, which may cause the thread size parameters to deviate from the original specifications.

[0004] Therefore, a toothed bar wire output machine was designed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a threaded rod extrusion machine. It solves the problem that when processing extra-long threaded rods, some equipment is not connected to the production line at the feeding or discharging point, causing the threaded rods to fall directly into the collection basket. Furthermore, the lack of support during the feeding and discharging stages causes the extra-long threaded rods to fall slightly due to their own weight, which may lead to the thread size parameters deviating from the set standard.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A toothed bar feeder includes a toothed bar feeder body. An installation platform one and an installation platform two are fixedly arranged on the outer wall of the toothed bar feeder body. A support part is provided on the inner wall of the installation platform one, and the support part is used to provide auxiliary support for the feeding process of the toothed bar.

[0007] Preferably, an electric push rod 2 is fixedly installed on the inner wall of the second mounting platform, and an installation block is fixedly installed at the end of the output shaft of the electric push rod 2.

[0008] Preferably, the top of the second mounting platform is fixedly mounted with two limiting strips by bolts. The two limiting strips are located on both sides of the mounting block and are used to limit the movement trajectory of the mounting block.

[0009] Preferably, the top of the installation platform is provided with a sliding groove, and the support part includes a shell, which passes through the sliding groove and is slidably connected to the sliding groove.

[0010] Preferably, a drive rod is slidably installed inside the housing. The drive rod has a cross-shaped design, and the two ends of the drive rod in the horizontal direction are rounded. An electric push rod is fixedly installed at the bottom of the drive rod, and the bottom of the electric push rod is fixedly connected to the mounting block.

[0011] Preferably, two round rods are fixedly installed inside the housing, and the two round rods are located on both sides of the drive rod and are symmetrically distributed.

[0012] Preferably, two connecting rods are rotatably mounted on the outer walls of the two round rods respectively, and the side of the two connecting rods that are close to each other is designed with an arc shape. The bottom outer walls of the two connecting rods are elastically connected by springs.

[0013] Preferably, when the drive rod approaches and contacts the two connecting rods, it can drive the two connecting rods to rotate along the hinge point with the round rod.

[0014] Preferably, a second roller is mounted on the top of the drive rod via a ball joint, and a first roller is mounted on the top of each of the two connecting rods via a ball joint.

[0015] Preferably, the mounting portions of the two connecting rods and the round rod are designed in a circular shape to facilitate the rotation of the connecting rods.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves support for threaded rods of different thicknesses by setting up a support part. The central axis of the drive rod is aligned with the center of the thread rolling wheel by the second electric push rod to ensure symmetrical distribution of support force. The spacing of the first roller is adjusted by the first electric push rod to adapt to the thickness of the threaded rod. Combined with the dynamic following characteristics of the ball joint connection, it can effectively counteract the radial force during the processing of the thread rolling wheel and reduce the deviation of the thread pitch accuracy.

Example

[0024] Please see Figure 1-5A toothed bar feeder includes a toothed bar feeder body 1. A mounting platform 11 and a mounting platform 2 12 are fixedly mounted on the outer wall of the toothed bar feeder body 1. A support part 2 is provided on the inner wall of the mounting platform 11 to assist in the feeding process of the toothed bar. An electric push rod 2 4 is fixedly mounted on the inner wall of the mounting platform 2 12, and a mounting block 41 is fixedly mounted on the end of the output shaft of the electric push rod 2 4. Two limiting strips 121 are bolted to the top of the mounting platform 2 12, located on both sides of the mounting block 41, to limit the movement trajectory of the mounting block 41. A sliding groove 111 is formed on the top of the mounting platform 11. The support part 2 includes a housing 20, which passes through and is slidably connected to the sliding groove 111. A drive rod 22 is slidably mounted inside the housing 20. The drive rod 22 has a cross-shaped design and drives... The two ends of the rod 22 in the horizontal direction are rounded. An electric push rod 3 is fixedly installed at the bottom of the drive rod 22, and the bottom of the electric push rod 3 is fixedly connected to the mounting block 41. Two round rods 23 are fixedly installed inside the outer shell 20. The two round rods 23 are located on both sides of the drive rod 22 and are symmetrically distributed. Two connecting rods 21 are rotatably installed on the outer walls of the two round rods 23 respectively. The side of the two connecting rods 21 that is close to each other is designed with an arc shape. The bottom outer walls of the two connecting rods 21 are elastically connected by springs 24. When the drive rod 22 approaches and contacts the two connecting rods 21, it can drive the two connecting rods 21 to rotate along the hinge with the round rods 23. A roller 221 is installed on the top of the drive rod 22 by a ball joint. A roller 211 is installed on the top of the two connecting rods 21 by a ball joint. The mounting parts of the two connecting rods 21 and the round rods 23 are designed with a circular shape to facilitate the rotation of the connecting rods 21.

[0025] On the mounting platform 2 12 of the main body 1 of the toothed wire feeder, the electric push rod 2 4 is closely connected to the mounting block 41, and the two limit bars 121 are respectively located on both sides of the mounting block 41. When the electric push rod 2 4 drives the mounting block 41 to move, the limit bars 121 act like precise tracks, effectively limiting the movement trajectory of the mounting block 41. The sliding groove 111 on the inner wall of the mounting platform 11 is slidably connected to the outer shell 20 of the support part 2. The constraint of the sliding groove 111 ensures the linearity and stability of the movement of the outer shell 20. During the processing, the outer shell 20 can always move accurately along the sliding groove 111, thereby providing stable and reliable support for the toothed rack. In the support part 2, the central axis of the drive rod 22 is positioned in the middle of the two thread rolling wheels, so that the supporting force of the two rollers 211 on the toothed rack is symmetrically distributed; when the thread rolling wheels process the toothed rack, the radial force generated can be effectively offset by the symmetrical support structure, making the toothed rack more stable during the processing. When processing toothed rods of different thicknesses, activating the electric push rod 3 causes its output shaft to drive the roller 221 to move vertically within the housing 20. Since the drive rod 22 is in contact with the two connecting rods 21, the movement of the roller 221 causes the drive rod 22 to move synchronously, thereby driving the two connecting rods 21 to rotate along the round rod 23. When the drive rod 22 moves downwards, the distance between the two rollers 211 increases, easily accommodating thicker toothed rods; when the drive rod 22 moves upwards, the distance between the two rollers 211 decreases, perfectly fitting thinner toothed rods. This flexible distance adjustment method allows one machine to meet the processing needs of toothed rods of various specifications, greatly improving the versatility and utilization of the equipment. By setting a spring 24 to elastically connect the two connecting rods 21, when the drive rod 22 moves downward, the elastic force of the spring 24 causes the bottoms of the two connecting rods 21 to move closer to each other, thereby causing the two rollers 211 to open outward. When the drive rod 22 moves upward, the two ends of the connecting rod 21 contact the corresponding connecting rod 21, causing the spring 24 to be stretched, thereby driving the two connecting rods 21 to rotate in opposite directions, causing the two rollers 211 to move closer to each other. The drive rod 22 adopts a cross-shaped design, and the two ends in the horizontal direction are rounded to reduce friction when it comes into contact with the two connecting rods 21. The mounting points of the two connecting rods 21 and the round rod 23 are designed in a circular shape, which reduces the friction when the connecting rods 21 rotate. Driven by the drive rod 22, the connecting rods 21 can easily rotate along the hinge with the round rod 23. By combining the two connecting rods 21 to form a set of connecting rods, the weight of the connecting rods 21 is reduced. By reducing the weight of the connecting rods 21, the driving force required by the connecting rods during the movement is reduced, thereby reducing the energy consumption of the drive device. The lightweight connecting rods generate less heat under the same operating conditions, resulting in a stronger heat dissipation effect.

[0026] The gap between the top of the outer casing 20 and the slot where it slides to connect with the connecting rod 21 and the drive rod 22 is particularly small. Debris generated during conventional processing cannot enter the outer casing 20. Even if some small debris enters the interior of the outer casing 20, it will not affect the device inside the outer casing 20. The outer casing 20 can be cleaned by removing the cover plate. If debris enters the mounting platform 22 and the two limit strips 121 through the sliding groove 111, the bolts on the limit strips 121 can be loosened, the limit strips 121 can be removed, cleaned, and then reinstalled.

[0027] Workflow As needed, the support part 2 can be added to the feed and discharge points of the toothed bar extruder body 1, or it can be added to both points, such as... Figure 1As shown, the support part 2 is installed at the feed point of the toothed bar wire feeder body 1. Then, according to the thickness of the toothed bar to be processed, the distance between the two thread rolling wheels in the toothed bar wire feeder body 1 is adjusted to ensure that the distance between the thread rolling wheels matches the requirements of the toothed bar thread processing. Start the electric push rod 4. The output shaft of the electric push rod 4 drives the mounting block 41 to slide smoothly within the two limit bars 121. The mounting block 41 simultaneously drives the drive rod 22 and the outer casing 20 to move within the sliding groove 111 until the central axis of the drive rod 22 is accurately positioned in the middle of the two thread rolling wheels. Then, according to the actual thickness of the threaded rod, start the electric push rod 3. The output shaft of the electric push rod 3 drives the roller 221 to move vertically within the outer casing 20. Since the drive rod 22 is in contact with the two connecting rods 21, the roller 221... The movement of 21 will cause the drive rod 22 to move synchronously, thereby driving the two connecting rods 21 to rotate along the round rod 23. When the drive rod 22 moves down, the elastic force of the spring 24 causes the bottom of the two connecting rods 21 to move closer to each other, thereby causing the two rollers 211 to open outward and the distance between the two rollers 211 to increase, which can accommodate thicker toothed rods. When the drive rod 22 moves up, the distance between the two rollers 211 decreases, which can accommodate thinner toothed rods. By changing the vertical height of the drive rod 22, it is possible to adapt to toothed rods of different thicknesses. The toothed rod to be processed is accurately placed at the center of the two rollers 211; then the toothed rod feeder body 1 is started, the thread rolling wheel begins to rotate and process the toothed rod. During processing, the two rollers 211 of the support part 2 are symmetrically distributed on both sides of the toothed rod to form a clamping support. Since the central axis of the drive rod 22 is positioned between the two thread rolling wheels through the electric push rod 4, the supporting force of the two rollers 211 on the toothed rod is symmetrically distributed, which can effectively counteract the radial force generated by the thread rolling wheel during processing and reduce the radial swing amplitude of the toothed rod. This reduces the problem of thread pitch accuracy deviation caused by toothed rod wobbling.

Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
