[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] like Figure 1~Figure 2As shown, this embodiment proposes a thread rolling machine for screw processing, including: a frame 1; two thread rolling piles 2, the two thread rolling piles 2 are slidably arranged at one end of the frame 1, and a thread rolling space 201 is formed between the two thread rolling piles 2, and the thread rolling space 201 is used for thread rolling; a storage plate 3 is arranged on the frame 1, and is used for placing screws to be processed; an ejection block 4 is slidably arranged relative to the thread rolling pile 2, and the ejection block 4 is used to eject the screws to be processed into the thread rolling space 201.

[0045] In this embodiment, the frame 1 is the basic frame of the thread rolling machine, supporting all components, ensuring stability and structural strength, and facilitating installation, adjustment and maintenance. The thread rolling pile 2 is the core component of the thread rolling machine. The thread rolling pile 2 has a tooth groove. Two tooth piles are arranged at one end of the frame 1. Through the sliding structure design, the spacing between the two thread rolling piles 2 is adjustable to adapt to screw specifications of different sizes. The thread rolling space 201 is formed between the two tooth piles. The tooth groove is used to contact the screw to be processed. By rotating the thread rolling pile 2, the screw to be processed forms a thread path. The storage plate 3 is located on the frame 1, which is used to carry the screws to be processed and ensure that the screws enter the thread rolling space 201 in an orderly manner, which is convenient for continuous operation and improves efficiency. The ejection block 4 is slidably arranged relative to the two thread rolling piles 2. Its function is to quickly and accurately eject the screws to be processed on the storage plate 3 into the thread rolling space 201, reduce manual operation, and improve the safety performance of the thread rolling machine.

[0046] The working process of the thread rolling machine is as follows: first, the operator slides the ejection block 4 to the left, so that the ejection block 4 is away from the thread rolling space 201, and the ejection block 4 accumulates force. Then the screw to be processed is placed on the storage plate 3, and then the distance between the two thread rolling piles 2 is adjusted according to the needs. The distance between the two thread rolling piles 2 is the diameter of the screw after processing, and then the ejection block 4 is released, and the ejection block 4 slides to the right, and the screw to be processed is ejected from the storage plate 3 into the thread rolling space 201. Then the operator uses an external drive, such as a motor, to rotate the two thread rolling piles 2 to roll the screw to be processed. During the thread rolling process, there is no need to adjust the position of the screw to be processed by manpower, which has high safety. When one screw is processed, the next screw to be processed can be moved to the thread rolling space 201 using the same steps, which has high continuous productivity. After the thread rolling is completed, the operator uses an appropriate tool to remove the processed screw from between the two thread rolling piles 2.

[0047] like Figure 1~Figure 2 As shown, optionally, it also includes: an ejection rod 5 is slidably set at one end of the storage plate 3 away from the tooth-rolling pile 2, and the ejection block 4 is set at one end of the ejection rod 5 close to the tooth-rolling pile 2, and the ejection rod 5 is used to drive the ejection block 4 to move.

[0048] In this embodiment, the linkage mechanism of the ejection rod 5 and the ejection block 4 is introduced to optimize the automatic pushing process of the screw to be processed. The ejection rod 5 is slidably installed at one end of the storage plate 3 away from the thread rolling pile 2. The function of the ejection rod 5 is to drive the ejection block 4 to move, so that the ejection block 4 moves along the width direction of the storage plate 3, and the screw to be processed is ejected into the thread rolling space 201. The specific working process is as follows: the operator can pull the ejection rod 5 to the left, at which time the ejection rod 5 drives the ejection block 4 to move to the left, and then the operator places the screw to be processed on the storage plate 3. After the operator adjusts the distance between the two thread rolling piles 2, the operator releases the ejection rod 5, and the ejection rod 5 moves to the right, driving the ejection block 4 to move to the right, so that the ejection block 4 ejects the screw to be processed from the storage plate 3 into the thread rolling space 201. Through the cooperation of the ejection rod 5 and the ejection block 4, the automatic and precise pushing of the screw to be processed is realized, which reduces manual intervention, not only improves the work efficiency, but also enhances the pushing accuracy of the screw to be processed. The process from placing the screws to be processed to thread rolling is simplified, making the entire production process smoother, suitable for high-speed continuous operation and suitable for mass production environments.

[0049] like Figure 1~Figure 2 As shown, optionally, it also includes: an elastic member 6 is sleeved on the ejection rod 5, and two ends of the elastic member 6 act on the storage plate 3 and the ejection block 4 respectively, and the elastic member 6 is used to provide a force for the ejection rod 5 to approach the tooth-rolling pile 2.

[0050] In this embodiment, the elastic member 6 can be a spring. The setting of the elastic member 6 adds the functions of dynamic buffering and automatic resilience to the ejection rod 5 and the ejection block 4. The elastic member 6 is set on the ejection rod 5, and its two ends are respectively connected to the storage plate 3 and the ejection block 4. The specific working process is as follows: the operator pulls the ejection rod 5 to the left, driving the ejection block 4 to move to the left. At this time, the elastic member 6 is subjected to a pulling force to the left, and the elastic member 6 is compressed. When the operator releases the elastic rod, the elastic member 6 loses the pulling force, and the elastic member 6 resets, so that the elastic rod and the elastic block move to the right, so that the elastic block ejects the screw to be processed into the thread rolling space 201, reducing manual operation. The setting of the elastic member 6 enables the ejection rod 5 to automatically reset and maintain a continuous working cycle.

[0051] like Figure 1~Figure 3 As shown, optionally, it also includes: a rack 7 is arranged at one end of the ejection rod 5 away from the thread rolling pile 2; and a toothless gear 8 is rotatably arranged on the storage plate 3 and meshed with the rack 7.

[0052] In this embodiment, the operator can drive the toothless gear 8 to rotate through an external drive, such as a motor, to drive the rack 7 to move to the left, so that the ejection rod 5 moves to the left, compresses the elastic member 6, and moves the ejection block 4 to the left. When the tooth pressure of the toothless gear 8 is disengaged from the rack 7, the elastic member 6 loses its limiting force. At this time, the elastic member 6 cancels compression and resets, and the ejection rod 5 slides to the right, driving the ejection block 4 to slide to the right, so that the ejection block 4 ejects the screw to be processed into the thread rolling space 201. The operator can adjust the ejection stroke and ejection force of the ejection rod 5 by setting the tooth ratio of the toothless gear 8 and the rack 7 to adapt to screws with different processing requirements.

[0053] like Figure 1~Figure 4 and Figure 6 As shown, optionally, the storage plate 3 has a through slot 301 , the through slot 301 points to the thread rolling space 201 , and the screw rod of the screw to be processed passes through the through slot 301 .

[0054] In this embodiment, a through slot 301 is provided on the storage plate 3, and the through slot 301 can carry the nut of the screw to be processed. When the ejection block 4 moves to the right, the ejection block 4 contacts the nut of the screw to be processed, and ejects the screw to be processed in the through slot 301 into the thread rolling space 201. The setting of the through slot 301 not only serves to limit the screw to be processed, but also allows the screw to be processed to be ejected smoothly into the thread rolling space 201.

[0055] like Figure 1~Figure 4 and Figure 6 As shown, optionally, it also includes: there are two pairs of clamps 9, the two pairs of clamps 9 are slidably set on the storage plate 3, the two pairs of clamps 9 have a sliding groove 901, and the two pairs of clamps 9 form a sliding space 902 after sliding, and the nuts of the screws to be processed slide along the sliding space 902.

[0056] In this embodiment, when the operator places the screw to be processed in the through slot 301, the bottom of the nut of the screw to be processed contacts the upper part of the through slot 301, and then the operator slides the two clamping plates 9, and the inner walls of the two slide slots 901 on the two clamping plates 9 contact the peripheral side of the nut of the screw to be processed. When the ejection block 4 moves to the right, the ejection rod 5 contacts the nut of the screw to be processed, and ejects the screw to be processed from the sliding space 902 to the thread rolling space 201. The setting of the clamping plates 9 and the slide slots 901 makes the sliding of the screw to be processed smoother, and at the same time reduces the deviation from the sliding track when the screw to be processed slides.

[0057] like Figure 1 to Figure 6As shown, optionally, it also includes: there are two slide rails 10, the two slide rails 10 are slidably set on the frame 1, and are located between the storage plate 3 and the thread rolling pile 2. A sliding channel 1001 is formed between the two slide rails 10, and the two ends of the sliding channel 1001 are respectively connected to the through groove 301 and the thread rolling space 201. After the two slide rails 10 slide, they are used to carry the nuts of the screws to be processed.

[0058] In this embodiment, before thread rolling, the operator first slides the two slide rails 10 and adjusts the distance between the two slide rails 10. The distance between the two slide rails 10 should be the same as the distance between the two thread rolling piles 2. After the ejection block 4 contacts the nut of the screw to be processed, the screw to be processed moves from the storage plate 3 to between the two slide rails 10. The two slide rails 10 contact the lower end of the nut of the screw to be processed respectively. The screw to be processed moves from the sliding channel 1001 formed between the two slide rails 10 to the thread rolling space 201. The setting of the slide rail 10 can guide the screw to be processed into the thread rolling space 201.

[0059] like Figure 1 to Figure 6 As shown, optionally, it also includes: a material barrel 11 is arranged above the storage plate 3 and is connected to the through groove 301, and the material barrel 11 is used to transport the screws to be processed.

[0060] In this embodiment, the operator can vertically place the screw to be processed into the barrel 11. It should be noted that at this time, the axis of the screw to be processed is parallel to the axis of the barrel 11.

[0061] like Figure 1 to Figure 6 As shown, optionally, it also includes: a driving member 12 is lifted and set on the frame 1, located between the two tooth-rolling piles 2; a cleaning roller 13 is set on the driving member 12, the cleaning roller 13 is used to clean the two tooth-rolling piles 2, and the driving member 12 is used to drive the cleaning roller 13 to rotate.

[0062] In this embodiment, when the operator wants to clean the two tooth-rolling piles 2, the two tooth-rolling piles 2 are first slid, and the distance between the two tooth-rolling piles 2 is adjusted so that the distance between the two tooth-rolling piles 2 can accommodate a cleaning roller 13. It should be noted that the axis of the cleaning roller 13 is parallel to the axis of the two tooth-rolling piles 2. Then the driving member 12 is lowered, and the cleaning roller 13 is lowered so that the cleaning roller 13 is located between the two tooth-rolling piles 2. Then the driving member 12 is operated to rotate the cleaning roller 13, and the cleaning roller 13 cleans the two tooth-rolling piles 2.

[0063] like Figure 1 to Figure 6 As shown, optionally, the cleaning roller 13 has a plurality of axially distributed water outlets 1301 ; further comprising: a water spraying member 14 is clamped in the cleaning roller 13 , the water spraying member 14 has a plurality of axially distributed water spraying nozzles 1401 , and the water spraying nozzles 1401 correspond one-to-one to the water outlets 1301 .

[0064] In this embodiment, when cleaning, the operator can introduce water into the water spray part 14. After the water flows into the water spray part 14, it flows from the water spray nozzle 1401 to the water spray port, and then flows to the tooth-rolling pile 2, thereby improving the cleaning effect and making the tooth-rolling pile 2 clean more thoroughly.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
