[0001] The present application relates to the field of cold rolling forming equipment, and in particular to a thread rolling machine for fastener processing. Background Art
[0002] Fasteners are a type of mechanical parts that are used for fastening and are widely used, including bolts, studs and other common connection parts in daily life. Among the various processes of manufacturing fasteners, the step of machining the thread surface on the surface of the fastener is particularly important, and the main machine used to machine the thread surface on the surface of the fastener is the thread rolling machine.
[0003] Reference Figure 1 The fasteners currently processed are pipe fittings, and the diameters of the two ends of the pipes are different, thus forming a large head end and a section to be processed on the pipe fittings, and the diameter of the large head end is larger than the diameter of the large head end. The outer wall of the large head end is a polygon. Common thread rolling machines are provided with a feeding trough. Before processing the pipe-shaped fasteners, the staff manually places the pipe fittings into the feeding trough, and then performs thread rolling on the pipe fittings.
[0004] Regarding the above-mentioned related technologies, the inventor believes that since the pipe fittings have an asymmetric structure, workers are required to place a large number of pipe fittings one by one and manually, which not only makes the workers easily fatigued, but also reduces the efficiency of thread rolling for a large number of pipe fittings, which is not conducive to thread rolling for a large number of pipe fittings. Summary of the invention

[0009] The mounting cylinder is provided with a through hole communicating with the upper end of the material guide trough, and the discharging push plate is provided with a material storage hole;
[0010] The thread rolling machine also includes a second mounting plate and a loading slide block which reciprocates on the second mounting plate, and the loading slide block is provided with a loading groove which can be opposite to the material storage hole.
[0011] By adopting the above technical scheme, before thread rolling a large number of pipe fittings, a large number of pipe fittings are first placed in the installation cylinder, and then the motor is started to rotate the turntable. A large number of pipe fittings on the turntable can be discharged into the material guide trough through the through holes one by one, and the pipe fittings automatically slide down in the material guide trough by their own gravity. Then the pipe fittings slide horizontally into the discharge trough through the lower end of the material guide trough and make the section to be processed face the direction of the thread rolling wheel.

[0047] Reference Figure 3 A vertical plate 311 is fixedly mounted on the first mounting plate 31, and a discharge push plate 38 is passed through the vertical plate 311. A temporary storage cylinder 371 is fixedly connected to the lower end of the discharge chute 37. The temporary storage cylinder 371 is perpendicular to the first mounting plate 31 and fixed to the vertical plate 311, and the lower end of the temporary storage cylinder 371 is suspended above the discharge push plate 38. After the pipe fittings 1 pass through the discharge chute 37 and slide into the temporary storage cylinder 371, multiple pipe fittings 1 to be processed can be temporarily stored, which is beneficial to the subsequent loading work.

[0050] Reference Figure 5 The upper surface of the feeding slider 43 is arranged lower than the upper surface of the first mounting plate 31, and a feeding groove is provided on the upper surface of the feeding slider 43 along the length direction of the guide rail 42. The end of the feeding groove close to the thread rolling machine is connected to the side wall of the feeding slider 43, and the port of the feeding groove is arranged opposite to the limit plate 6. The bottom of the feeding groove is an arc surface, which is conducive to aligning the pipe 1 in the feeding groove with the gap between the two thread rolling wheels 5.

The diameter of the spring 46 is smaller than the diameter of the connecting sleeve 45, so that the connecting sleeve 45 can push the spring 46. A first limiting rod 411 is vertically fixed on the upper plate surface of the second mounting plate 41. A connecting plate 431 is fixedly connected to the side wall of the feeding slider 43, and a second limiting rod 432 is horizontally fixedly connected to the connecting plate 431. When the sliding push rod 44 pushes the pipe 1 to be located between the two thread rolling wheels 5, the second limiting rod 432 abuts against the first limiting rod 411, thereby facilitating accurate processing of the pipe 1.

The distance between the third limiting rod 451 and the second limiting rod 432 is smaller than the length of the sliding push rod 44, so as to ensure that the sliding push rod 44 can always be inserted into the feeding push block.
[0053] In normal use, the second electric push rod 47 drives the connecting sleeve 45 and the spring 46 to first push the feeding slide 43 toward the thread rolling wheel 5, and then the second electric push rod 47 continues to push the pipe 1 in the feeding trough to between the two thread rolling wheels 5 until the second limit rod 432 and the first limit rod 411 abut against each other and stop. After the thread rolling of the pipe 1 is completed, the second electric push rod 47 pulls the sliding push rod 44, so that the third limit rod 451 drives the connecting plate 431 and completes the reset of the feeding slide 43.
[0054] Reference Figure 1 The limiting plate 6 is vertically located between the two thread rolling wheels 5, and the thickness of the limiting plate 6 is smaller than the diameter of the section to be processed 12. A right-angled limiting notch is formed on the side of the limiting plate 6 facing the loading slider 43, and the depth of the limiting notch is consistent with the length of the section to be processed 12. When the pipe 1 is thread-rolled, after the pipe 1 is pushed between the two thread rolling wheels 5, the section to be processed 12 can be located in the notch and limited by the notch, so that the thread rolling wheel 5 can accurately thread the section to be processed 12.
[0055] Reference Figure 1 , the notch of the discharge trough 7 is tilted upward, and the upper end of the discharge trough 7 is located between the two thread rolling wheels 5, and the lower end of the discharge trough 7 is located below the second mounting plate 41.
