Description

Technical Field

[0001] The utility model relates to the technical field of thread rolling machines, in particular to a thread rolling machine for processing bolts. Background Art

[0002] The thread rolling machine is a multifunctional cold extrusion forming machine tool, which is mainly used for rolling threads, straight lines, diagonal lines, etc. on workpieces in a cold state, as well as rolling straight teeth, helical teeth and helical spline gears. This machine squeezes the workpiece through two threaded rollers to make the outer surface of the part plastically deformed to form threads;

[0003] Existing thread rolling machines often rely on manual feeding when rolling the workpiece through two thread rollers. However, manual feeding is inefficient and it is difficult to ensure the continuity and efficiency of the thread rolling operation. Especially in mass production, manual feeding will become a bottleneck restricting the production speed. At the same time, manual feeding is likely to lead to inaccurate feeding position, which in turn affects the quality and precision of the thread rolling. Each feeding requires workers to rely on experience and feel, and it is difficult to ensure the consistency of each feeding, which increases the scrap rate and rework rate. In addition, when the workpiece is rolled by manual feeding, the worker needs to frequently contact the machine and the workpiece during the operation. Accidents may occur if they are not careful, posing a threat to the safety of the workers. Utility Model Content

[0023] like Figure 2As shown, a cylinder 12 is fixedly installed on one side of one of the material boxes 7, and the cylinder 12 is connected to an external pump station through a pipeline. A discharge pipe 11 is fixedly installed on one side of the other material box 7. First side plates 13 are fixedly installed on both sides of the two material boxes 7, and a first connecting plate 14 is fixedly connected between the two first side plates 13 on the same side. An adjusting screw 15 is threadedly connected to the center position of the first connecting plate 14. With the arrangement of the first connecting plate 14 and the adjusting screw 15, the horizontal displacement adjustment of the mounting frame 10 can be facilitated. The material boxes 7 located above and below the first side plate 13 are also fixedly installed with second side plates 20, and two slide grooves 21 are provided in the second side plate 20.

[0024] like Figure 2-Figure 6 As shown, the mounting frame 10 includes two U-shaped plates 17, two second connecting plates 18 are fixedly installed on one side of the two U-shaped plates 17, and the first shaft seats 19 are fixedly installed on the opposite sides of the two second connecting plates 18, and the pulley 25 is rotatably installed between the two first shaft seats 19 through a fixed axis. A third connecting plate 22 is fixedly connected between the two U-shaped plates 17, and a second shaft seat 23 is fixedly installed on one side of the third connecting plate 22. One side of the adjusting screw 15 is rotatably installed in the second shaft seat 23, and one side of the second connecting plate 18 is also fixedly installed on one side of the clamping plate 9, and a through groove 16 is opened in the clamping plate 9.

One side of the second bottom plate 24 extends through the through groove 16 to the other side of the clamping plate 9. The horizontal movement of the clamping plate 9 is realized through the mounting frame 10 composed of the third connecting plate 22, the second connecting plate 18, the first shaft seat 19, the second side plate 20, the third connecting plate 22 and other components, and then the distance between the two clamping plates 9 can be adjusted according to the diameter of the workpiece. The two pulleys 25 are connected with a belt 26 for transmission. With the help of the belt 26 between the two pulleys 25, it is convenient for the two clamping plates 9 to limit the clamping of the workpiece, and ensure that the workpiece can fall smoothly by gravity.

[0025] It should be noted that the utility model is a thread rolling machine for bolt processing. Before thread rolling the workpiece, the workpiece can be placed in turn between the two clamping plates 9 in the two material boxes 7 from the upper channels of the two material boxes 7, and the outer sides of the belts 26 in the two clamping plates 9 are in contact with the outer surface of the workpiece, thereby ensuring that the workpiece automatically falls down in the later stage and improving the position accuracy of the workpiece push-out, thereby ensuring that the workpiece can smoothly enter between the two thread rolling mechanisms 4, and then, the external controller automatically pushes the workpiece placed on the two second bottom plates 24 to one side according to the thread rolling progress of the single workpiece, so that the workpiece enters between the two thread rolling mechanisms 4 through the discharge pipe 11, and then the two thread rolling mechanisms 4 are squeezed toward the workpiece through the output end of the hydraulic box 3, and the corresponding thread rolling mechanisms 4 are driven to operate by means of the two output ends in the main box 2, so that the outer surface of the workpiece can be thread rolled, and then, the output end of the cylinder 12 is retracted, so that the workpiece at the lowest position in the material box 7 can fall onto the two second bottom plates 24, waiting for the next push-out by the cylinder 12;

[0026] When it is necessary to adjust the distance between the two clamping plates 9, i.e., the two belts 26, according to workpieces of different diameters, it is only necessary to rotate the handwheels on one side of the two adjusting screws 15 by the same process, so that one side of the adjusting screw 15 rotates in the second shaft seat 23, and the adjusting screw 15 also rotates in the screw hole in the first connecting plate 14, so that the third connecting plate 22 can be pushed and pulled. As a result, the third connecting plate 22 synchronously drives the two U-shaped plates 17 to move, so that the two sides of the two U-shaped plates 17 can move horizontally between the corresponding two second side plates 20 through the pins, and the U-shaped plate 17 drives the clamping plate 9 to move through the two second connecting plates 18. At the same time, the second connecting plate 18 also drives the pulley 25 to move synchronously through the first shaft seat 19 on one side, so as to adjust the position of the belt 26 horizontally.
