The bottom inner wall of the fixing groove is set as a hollow structure. A first connecting hole is provided on the outer wall of the side of the workbench close to the bottom. The inner wall of the first connecting hole is slidably connected to the connection pads distributed at equal distances. A movable frame is provided on the top outer wall of several connection pads. A second connecting hole is provided on one side of the top outer wall of the workbench, and the movable frame is slidably connected to the inner wall of the second connecting hole.

The raw material cutting device for screw processing and its processing technology disclosed in the present invention have the effects of stable cutting process, strong feeding and discharging automation, and high cutting efficiency.

[0004] However, in actual application, the device still has some areas that need to be improved. Specifically, the device described in the above document transports raw materials through inlet rollers. During the transportation of raw materials, due to the influence of various factors, such as collisions during transportation, the gravity of the raw materials themselves, etc., the raw materials may be slightly bent.

Once the raw material gets stuck at the inlet roller, it will not only lead to the interruption of the entire cutting process and reduce production efficiency, but may also cause damage to the inlet roller and cutting components, increasing the maintenance cost of the equipment. More seriously, this jamming phenomenon will directly affect the production quality of the screws, making the cut screw raw materials inaccurate in size and irregular in shape, thereby increasing the defective rate of cutting.

[0038] 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 described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] like Figures 1 to 9 As shown, the present invention provides a raw material cutting device for screw processing, comprising a main body 1, an introduction roller 2, a sleeve 3 and a cutting assembly 10, and further comprising:

[0040] a straightening mechanism 4, which is arranged on one side of the main body 1;

[0041] The straightening mechanism 4 includes a mounting shell 401 fixedly connected to one side of the main body 1, a gear ring 402 is rotatably connected to the interior of the mounting shell 401, a gear 1 403 meshing with the gear ring 402 is rotatably connected to the interior of the mounting shell 401, and there are four gears 1 403, and four mounting rods 404 are provided on one side of the four gears 1 403, and a connecting block 1 408 located inside the mounting rod 404 is fixedly installed on one side of the four gears 1 403, and four straightening plates 405 are fixedly sleeved on one end of the four mounting rods 404 close to the center of the mounting shell 401, and a motor 1 406 is fixedly installed on one side of the outer surface of the mounting shell 401, and the output end of the motor 1 406 extends to the interior of the mounting shell 401 and is fixedly installed with a gear 2 407 meshing with the gear ring 402;

[0042] The above solution is adopted: the operator inserts the screw material to be cut into the interior of the mounting housing 401 and enters between the four straightening plates 405. At this time, the motor 1 406 can be driven to rotate the gear 2 407. Since the gear 2 407 and the gear 1 403 are respectively engaged with the gear ring 402, the rotating gear 2 407 drives the gear ring 402 to rotate, and the gear ring 402 drives the gear 1 403 to rotate. The gear 1 403 drives the connecting block 1 408 to slide inside the mounting rod 404, and pushes the mounting rod 404 and the straightening plates 405 to move toward the surface of the material. The four straightening plates 405 simultaneously squeeze the material, thereby straightening the bent material.

[0043] After the correction is completed, the introduction roller 2 can be driven to rotate, and the introduction roller 2 will drive the raw material through the pad 3 into the interior of the cutting assembly 10. When the raw material moves to the designated cutting position, the cutting assembly 10 can be driven, and the cutting assembly 10 can cut the raw material.

[0044] like Figure 3 、 Figure 6 and Figure 7 As shown, it also includes:

[0045] The cleaning assembly 5 is arranged on one side of the main body 1. The cleaning assembly 5 includes two bidirectional hydraulic cylinders 501 arranged on one side of the main body 1. The output ends of the two bidirectional hydraulic cylinders 501 are fixedly installed with cleaning brushes 502.

[0046] The above solution is adopted: through the design of the cleaning component 5, during the process of the inlet roller 2 conveying the raw material, the bidirectional hydraulic cylinder 501 can be driven so that its output shaft pulls the two cleaning brushes 502 toward the surface of the raw material and contacts the surface of the raw material, so that the cleaning brushes 502 can clean the rust on the surface of the raw material, thereby ensuring the quality of subsequent processing.

[0047] like Figure 3、 Figure 4 and Figure 6 As shown, it also includes:

[0048] The drive assembly 6 is provided on one side of the main body 1 and includes a worm 602 fixedly connected to the square housing 601 and fixedly mounted on one side of the gear 2 407. The worm 602 is located inside the square housing 601 and is rotatably connected to the worm wheel 603 inside the square housing 601.

[0049] The swing mechanism 7 is arranged at the bottom end of the worm gear 603 and can drive the cleaning assembly 5 to move back and forth.

[0050] Adopting the above scheme: through the design of the driving component 6, during the rotation of gear 1 403, the worm 602 will be driven to rotate, because the worm 602 is engaged with the worm wheel 603, and the rotating worm 602 will drive the worm wheel 603 to rotate, and the worm wheel 603 enables the swing mechanism 7 to drive the cleaning component 5 to move back and forth. Through the movement of the cleaning component 5, the cleaning effect of the cleaning component 5 can be improved.

[0051] like Figure 6 and Figure 7 As shown, the swing mechanism 7 includes a rotating disk 701 fixedly connected to the bottom end of the worm gear 603, a sliding ring 702 is provided at the bottom end of the rotating disk 701, and the sliding ring 702 is connected to the cleaning brush 502, and a connecting ring 2 703 located inside the sliding ring 702 is fixedly installed at the bottom end of the rotating disk 701.

[0052] The above solution is adopted: through the design of the swing mechanism 7, during the rotation of the worm gear 603, the rotating disk 701 will be driven to rotate, and the rotating disk 701 will drive the connecting ring 2 703 to slide inside the sliding ring 702. During the sliding process, the sliding ring 702 will be driven to move back and forth, and the sliding ring 702 will drive the cleaning brush 502 to move back and forth on the surface of the raw material. Finally, the worm 602 is linked to the gear 1 403 to make the worm gear 603 drive the cleaning brush 502 to move back and forth on the surface of the raw material, thereby increasing the cleaning effect of the cleaning brush 502 on rust and improving the quality of subsequent processing.

[0053] like Figure 2 、 Figure 3 and Figure 6 As shown, it also includes:

[0054] The limiting assembly 8 includes a limiting rod 801 fixedly connected to one side of the main body 1. The surface of the limiting rod 801 is slidably connected to the limiting slider 802, and one side of the limiting slider 802 is connected to the surface of the bidirectional hydraulic cylinder 501;

[0055] The distance between the limiting slider 802 and the sleeve 3 is smaller than the distance between the limiting slider 802 and the main body 1 .

[0056] The above-mentioned scheme is adopted: through the design of the limiting component 8, when the cleaning brush 502 moves, the limiting slider 802 will be driven to slide on the surface of the limiting rod 801, and then the limiting rod 801 can limit the limiting slider 802 and the cleaning brush 502, thereby ensuring that the cleaning brush 502 can move smoothly, and without affecting the operation of the equipment, the distance between the limiting slider 802 and the sleeve pad 3 is smaller than the distance between the limiting slider 802 and the main body 1; this design is mainly to shorten the distance between the straightening mechanism 4 and the driving component 6; after the distance between the two is reduced, the length of the support component 9 can be reduced. After the length of the support component 9 is reduced, the twisting damage to the support component 9 can be reduced, thereby improving the service life of the support component 9.

[0057] like Figure 2 and Figure 6 As shown, it also includes:

[0058] The support assembly 9 is arranged on one side of the mounting shell 401. The support assembly 9 includes a support rod 901 fixedly connected to one side of the mounting shell 401. The internal rotation of the support rod 901 is connected to a rotating ring 902 located on the surface of the worm 602. The support rod 901 is located on the surface of the worm 602, and the worm 602 can rotate inside the support rod 901.

[0059] The above solution is adopted: through the design of the support component 9, when the gear 2 407 drives the worm 602 to rotate, the worm 602 will drive the rotating ring 902 to rotate inside the support rod 901. Since the surface of the rotating ring 902 fits the inner wall of the support rod 901, the rotating ring 902 cooperates with the support rod 901, thereby supporting and limiting the worm 602.

[0060] like Figure 6 and Figure 7 As shown, two limiting rings 11 are fixedly mounted on the surface of the worm gear 603 , and opposite sides of the two limiting rings 11 are in contact with the surface of the square housing 601 .

[0061] The above solution is adopted: through the design of the limiting ring 11, since the opposite sides of the two limiting rings 11 are in contact with the surface of the square shell 601, the two limiting rings 11 cooperate with each other to support the worm gear 603 and the rotating disk 701.

[0062] like Figure 4 As shown, the mounting rod 404 and the straightening plate 405 are fixed by bolts, and the straightening plate 405 is designed to be arc-shaped; hard cotton pads are attached to both ends of the inner surface of the straightening plate 405, and the metal gasket partially covers the inner surface of the straightening plate 405. An electromagnetic device is also provided on the straightening plate, which is used to start and absorb the screw when the straightening plate applies pressure to the screw.

[0063] The above scheme is adopted: through the design of the mounting rod 404 and the straightening plate 405, since the mounting rod 404 and the straightening plate 405 are fixed by bolts, the stability thereof can be increased, and the straightening plate 405 adapted thereto can be replaced according to the size of the raw material, thereby improving the diversity of the equipment, and the arc-shaped design of the straightening plate 405 can fully fit with the raw material, ensuring that the straightening plate 405 can correct the raw material, and then the hard gasket provided acts as a consumable, and the hard cotton pad is formed by squeezing multiple layers of cotton pads. As a consumable, it can extend the life of the straightening plate, while reducing the rigid contact with the screws and protecting the integrity of the screws. On the other hand, an electromagnetic device is provided. When the straightening plate is working, the electromagnetic device is activated, and suction is applied to the screws, which can not only further strengthen the fixation, but also reduce the splashing of waste chips from the screws, while reducing the work of cleaning.

[0064] like Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown, there are two cleaning brushes 502, and the bristles on the opposite sides of the cleaning brushes 502 are both designed with nylon, and the two cleaning brushes 502 are both designed in an arc shape. The bristles of the cleaning brushes 502 are arranged in a wave structure along the radial direction of the cleaning brush 502, and are symmetrical from the two ends to the middle, and the height of the wave crest increases successively. A baffle is provided on one side of the four connecting blocks 408, and one side of the baffle is in contact with the surface of the mounting rod 404.

[0065] The above solution is adopted: through the design of the cleaning brush 502, since the bristles on the opposite side of the cleaning brush 502 are all nylon, the movement of the raw materials will not be blocked during the contact with the raw materials, and the cleaning brush 502 is designed to be arc-shaped, so there will be no dead angle, thereby increasing its cleaning effect, and the bristles of the cleaning brush 502 are arranged in a wave structure along the radial direction of the cleaning brush 502, and are symmetrical from the two ends to the middle; through the wave structure design, the height of the wave crest can be increased, which is conducive to increasing the squeezing force of the wave crest on the raw materials, and the cleaning force of the raw materials will be greater. , in this way, the cleaning effect of the raw materials will be better; when subjected to great pressure, the trough can accommodate the material squeezed by the crest, so that the raw materials will not be unable to move after being squeezed; from both ends to the middle, the height of the crest increases successively; the advantage of this design is that the height of the bristles in the middle position can be appropriately increased, which can effectively improve the service life of the cleaning brush; through the design of the connecting block 408, since a baffle is provided on one side of the connecting block 408, the baffle can limit the connecting block 408, ensuring that the mounting rod 404 can move stably.

[0066] The working principle and use process of the present invention:

[0067] First, the operator can insert the screw material to be cut between the four straightening plates 405, and then drive the motor 1 406 to rotate the gear 2 407. During the rotation of the gear 2 407, the worm 602 will be driven to rotate, and the worm 602 will drive the worm wheel 603, the rotating disk 701 and the connecting ring 2 703 to rotate, and the connecting ring 2 703 will slide inside the sliding ring 702 and push the sliding ring 702 to move back and forth. The sliding ring 702 will drive the cleaning brush 502, the two-way hydraulic cylinder 501 and the limiting slider 802 to slide on the surface of the limiting rod 801, and then the gear 2 407 will drive the gear ring 402, the gear 1 403 and the connecting block 1 408 to rotate, and the connecting block 1 408 will slide inside the mounting rod 404 and push the mounting rod 404 and the straightening plate 405 to move toward the surface of the material, and the four straightening plates 405 will squeeze the material at the same time, thereby straightening the bent material;

[0068] After straightening is completed, the inlet roller 2 can be driven, and the inlet roller 2 will transport the raw material to the cutting station. In the process of the inlet roller 2 transporting the raw material, the bidirectional hydraulic cylinder 501 can be driven so that its output shaft pulls the sliding cleaning brush 502 toward the surface of the raw material. Then the bristles on the opposite side of the cleaning brush 502 will contact the surface of the raw material, thereby cleaning the rust on the surface of the raw material, and using the cleaning brush 502 to move back and forth to increase the cleaning effect. After cleaning is completed, the raw material will be transported to the inside of the sleeve pad 3 and the cutting assembly 10. When the raw material moves to the position to be cut, the cutting assembly 10 can be driven to cut the raw material, and finally the operation process is completed.

[0069] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0070] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
