Technical Field
[0001] This utility model relates to the field of pre-bending and coiling pipe processing technology, specifically to an integrated pre-bending and coiling pipe processing device. Background Technology
[0002] A pipe rolling machine is a device that rolls flat materials into steel pipes. There are three common rolling methods. One is a three-roller pipe rolling machine, convenient for single-piece production. Two rollers are separate driving rollers, with the steel plate on top, and a third roller on top, the driven roller. When it presses down, it bends the steel plate into the corresponding arc shape, and when it rotates, it presses the plate into a pipe. Another type is equipment used for continuous steel pipe production. For small diameter pipes, the rolled plate is flattened and then directly pressed into a pipe using different rollers. The production line has a high-frequency welding machine for automatic welding, a cutter to smooth the weld joint, and a flying knife to cut the pipe. The products are various water pipes and straight seam welded pipes used in our industry. The third type uses rolled plates to produce large-diameter pipes, except that its weld seam is spiral-formed. Products include urban drainage pipes and oil pipeline pipes.
[0003] Existing tube rolling processing equipment requires manual insertion of the sheet metal into the equipment for pre-bending. The sheet metal is then pre-bent by three sets of pressure rollers on the equipment. When the sheet metal is manually inserted into the equipment, the pressure applied by the three sets of pressure rollers can easily cause the uninserted end to curl up, which is dangerous and can easily lead to production accidents. Therefore, we propose an integrated pre-bending tube rolling processing equipment to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide an integrated pre-bending and rolling tube processing device to solve the problem mentioned in the background art that when the plate is manually fed into the device, the three sets of pressure rollers on the rolling tube processing device can easily cause the un-felled end to curl up, which is dangerous and prone to production accidents.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated pre-bending and rolling pipe processing device, comprising a rolling machine body,
[0006] The tube winding machine body is rotatably mounted with a first pressure roller and two sets of second pressure rollers.

[0009] Preferably, the upper end of the push plate is inverted L-shaped, and the lower side of the push plate is flush with the upper side of the two sets of second pressure rollers.
[0010] Preferably, a first bevel gear is rotatably mounted inside the left end of the guide plate, and a second bevel gear is rotatably mounted inside the left end of the guide plate. The first bevel gear meshes with the second bevel gear. The rear side of the first screw at the left end of the tube winding machine body is fixedly connected to the second bevel gear. A slot is provided inside the left end of the bidirectional screw and the right end of the first bevel gear. A rotating shaft is movably inserted inside the left end of the guide plate, and two sets of locking blocks are provided at the right end of the rotating shaft.

As the push plate slides, it pushes the plate towards the inner wall of the first pressure roller and the second pressure roller, improving the convenience of feeding the plate and eliminating the need for manual feeding.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-6 One embodiment of this utility model is an integrated pre-bending and rolling pipe processing device, comprising a rolling machine body 1.
[0025] The tube winding machine body 1 is rotatably installed with a first pressure roller 2 and two sets of second pressure rollers 3. The two sets of second pressure rollers 3 are located below the first pressure roller 2. A guide plate 4 is fixedly installed on the front side of the tube winding machine body 1. Two sets of clamping plates 7 are provided on the upper rear side of the guide plate 4. An adjustment component is provided in the rear end of the guide plate 4, and a feeding component is provided in the front end of the guide plate 4. The device drives the two sets of clamping plates 7 to slide closer together through the adjustment component. The two sets of clamping plates 7 slide closer together to limit the plate material placed on the guide plate 4. Then, the feeding component moves to push the plate material placed on the guide plate 4 backward into the tube winding machine body 1, so that the first pressure roller 2 and the two sets of second pressure rollers 3 can pre-bend the plate material into a tube.
[0026] Furthermore, the adjustment assembly includes two sets of sliding grooves 5, which are symmetrically installed on the left and right sides inside the rear end of the guide plate 4. Slider 6 is slidably installed in each of the two sets of sliding grooves 5. The upper ends of the two sets of slider 6 are fixedly connected to the lower ends of the two sets of clamping plates 7. A bidirectional screw 8 is rotatably installed in the rear end of the guide plate 4. The left and right ends of the bidirectional screw 8 are threaded into the two sets of slider 6. This structure drives the two sets of slider 6 to slide closer in the two sets of sliding grooves 5 through the bidirectional screw 8, and the two sets of slider 6 drive the two sets of clamping plates 7 to slide closer, so that the two sets of clamping plates 7 can limit the feeding of materials of different specifications.
[0027] Furthermore, the feeding assembly includes two sets of first screws 9, which are rotatably installed inside the left and right ends of the guide plate 4. Synchronous pulleys 10 are fixedly installed at the rear ends of the two sets of first screws 9, and synchronous belts 11 are sleeved on the two sets of synchronous pulleys 10. A push plate 12 is slidably installed inside the front end of the guide plate 4. The lower sides of the left and right ends of the push plate 12 are connected to the two sets of first screws 9. This structure drives the push plate 12 to slide backward by rotating the two sets of first screws 9, the two sets of synchronous pulleys 10 and the synchronous belts 11, thereby pushing the plate placed on the guide plate 4 backward, so as to put the plate into the tube rolling machine body 1, which facilitates the rapid and stable feeding of the plate.
[0028] Furthermore, the upper end of the push plate 12 is inverted L-shaped, and the lower side of the push plate 12 is flush with the upper side of the two sets of second pressure rollers 3. This structure, based on the shape of the push plate 12, prevents the other end of the plate from warping when the push plate 12 pushes the plate into the tube rolling machine body 1.
[0029] Furthermore, a first bevel gear 13 is rotatably mounted inside the left end of the guide plate 4, and a second bevel gear 14 is rotatably mounted inside the left end of the guide plate 4. The first bevel gear 13 and the second bevel gear 14 mesh with each other. The rear side of the first screw 9 at the left end of the tube winding machine body 1 is fixedly connected to the second bevel gear 14. The left end of the bidirectional screw 8 and the right end of the first bevel gear 13 are both provided with slots 15. A rotating shaft 16 is movably inserted inside the left end of the guide plate 4. Two sets of locking blocks 17 are provided at the right end of the rotating shaft 16. When this structure pushes or the two sets of locking blocks 17 on the right end are movably inserted into the slots 15 at the left end of the bidirectional screw 8 or the right end of the first bevel gear 13, rotating the rotating shaft 16 can drive the bidirectional screw 8 or drive the two sets of first screws 9 to rotate through the first bevel gear 13 and the second bevel gear 14, which can respectively limit the plate and feed it into the tube winding machine body 1.
[0030] Furthermore, both sets of locking blocks 17 and the slots 15 inside the left end of the bidirectional screw 8 and the right end of the first bevel gear 13 are cross-shaped. The two sets of locking blocks 17 are adapted to the slots 15 inside the left end of the bidirectional screw 8 and the right end of the first bevel gear 13. Based on the shape of the two sets of locking blocks 17 and the slots 15 inside the left end of the bidirectional screw 8 and the right end of the first bevel gear 13, this structure allows the two sets of locking blocks 17 to be inserted into the slots 15 inside the left end of the bidirectional screw 8 and the right end of the first bevel gear 13, respectively, so that the bidirectional screw 8 and the first bevel gear 13 can be rotated.
[0031] Furthermore, limiting plates 18 are fixedly installed on opposite sides of both sets of sliders 6, and rollers 19 are rotatably installed on the lower side of opposite end of clamping plate 7 and on the upper side of the two sets of limiting plates 18. The four sets of rollers 19 are arranged in parallel vertically. After the plate is limited between the two sets of clamping plates 7, when the plate slides into the tube rolling machine body 1, the friction with the surface of the guide plate 4 is reduced by the four sets of rollers 19, which makes it easier to put the plate into the tube rolling machine body 1.
[0032] Furthermore, the first screws 9 on the left and right ends of the guide plate 4 have the same rotation direction of their surface threads, and the two sets of first screws 9 are arranged in parallel. According to the direction of the surface threads of the two sets of first screws 9, the two sets of synchronous pulleys 10 drive the two sets of first screws 9 to rotate through the synchronous belt 11. The rotation direction of the two sets of first screws 9 can make the push plate 12 slide backward synchronously.
[0033] Working principle: When pre-bending the sheet material, such as... Figure 2 and Figure 6As shown, pushing the rotating shaft 16 inserts the locking block 17 into the slot 15 at the left end of the bidirectional screw 8. Then, rotating the rotating shaft 16 drives the bidirectional screw 8 to rotate. The rotation of the bidirectional screw 8 causes the two sets of sliders 6, two sets of clamping plates 7, and two sets of limiting plates 18 to slide closer. The two sets of clamping plates 7 move closer to limit the left and right sides of the plate placed on the guide plate 4. Then, pulling the rotating shaft 16 causes the locking block 17 to slide into the slot 15 on the right side of the first bevel gear 13. Rotating the rotating shaft 16 drives the first bevel gear 13 to rotate. The rotation of the first bevel gear 13 drives the second bevel gear 14 to rotate. Figure 4 As shown, when the second bevel gear 14 rotates, it drives the two sets of first screws 9 to rotate through the two sets of synchronous pulleys 10 and synchronous belts 11. The rotation of the two sets of first screws 9 drives the push plate 12 to slide backward. While the push plate 12 slides backward, it pushes the plate placed on the guide plate 4 backward. The plate is pushed into the tube rolling machine body 1 by the force. When the plate slides between the two sets of clamping plates 7 and the two sets of limiting plates 18, the smoothness of the plate sliding is increased by the four sets of rollers 19. The plate is pre-bent by the first pressure roller 2 and the two sets of second pressure rollers 3. The above is the entire working principle of this utility model.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
