Description

Technical Field

[0001] The present invention relates to the technology in the field of steel processing, and in particular to a bending and forming production line for DTS brackets of new energy shelves. Background Art

[0002] Steel is a material with a certain shape, size and performance made from steel ingots, steel billets or steel through pressure processing; most steel processing is carried out through pressure processing to cause plastic deformation of the processed steel (billets, ingots, etc.); according to different steel processing temperatures, it can be divided into cold processing and hot processing.

[0003] For example, a cold rolling device for forming DTS brackets usually gradually bends the steel through multiple groups of cold rolling wheel sets, and then transports the bent steel to a stamping device, and uses the stamping device to punch out a special-shaped structure on the bent steel to complete the manufacture of the DTS bracket; in this manufacturing process, during the stamping process, the bending angle of the steel will change due to the influence of the punching force, resulting in a deviation in the bending angle of the steel and limited production yield.

[0033] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0034] 1. By sequentially arranging the first cold rolling wheel set to the tenth cold rolling wheel set from left to right, and arranging a stamping device on the left side of the first cold rolling wheel set; during operation, first, the stamping device punches a special-shaped structure on the steel, and then the steel is bent and formed into a DTS bracket through the first cold rolling wheel set to the tenth cold rolling wheel set; compared with the prior art, punching the special-shaped structure first and then bending and forming can reduce the problem that the bending angle of the steel does not meet the design requirements due to the acting force of the stamping device on the steel, thereby improving the production yield of the DTS bracket.

[0035] 2. Each cold rolling wheel is installed on the base through a right-hand screw and a left-hand screw, and the right-hand screw and the left-hand screw are connected through a connection structure; when adjusting the position of the wheel body, the right-hand screw can be rotated forward, and the left-hand screw is driven to rotate backward through the second bevel gear, the first bevel gear, and the third bevel gear. The forward rotation of the right-hand screw and the backward rotation of the left-hand screw drive the displacement of the wheel body to adjust the specific position of the wheel body; compared with the prior art, the displacement of the wheel body can be determined by recording the number of turns of the right-hand screw, so as to adjust the bending action parts of the wheel bodies of multiple cold rolling wheel sets to the same straight line, which is time-saving, labor-saving and has high adjustment accuracy.

[0036] Meanwhile, when the wheel body is operating, the rotation limit screw displaces, causing the limit teeth at the bottom of the limit block to abut against the threads of the forward rotation screw and the reverse rotation screw, thereby fixing the wheel body to the forward rotation screw and the reverse rotation screw. By providing power to the forward rotation screw through the drive unit, the wheel body can be driven to rotate to bend the steel. Compared with the prior art, while the position of the wheel body can be precisely adjusted through the structure of the forward rotation screw and the reverse rotation screw, the forward rotation screw and the reverse rotation screw are used to drive the rotation of the wheel body, simplifying the overall structure of the DTS bracket bending and forming production line, reducing the manufacturing cost, and facilitating subsequent maintenance and repair.

[0037] 3. The power unit only provides a power source for the cold rolling wheels of the second cold rolling wheel group and the ninth cold rolling wheel group, which can reduce the power consumption of the power unit and save energy. At the same time, the remaining multiple cold rolling wheel groups operate without power, which can make the bending force of the steel more balanced and is conducive to improving the yield of the DTS bracket bending and forming.

[0054] Please refer to Figure 1 As shown, the cold rolling wheel set 30 has multiple channels, and the multiple channels of the cold rolling wheel set 30 are sequentially arranged at intervals from left to right. Among the multiple channels of the cold rolling wheel set 30, the driving unit 40 is connected to the cold rolling wheel set in the second channel on the left and the cold rolling wheel set in the second channel on the right, and the stamping device 20 is arranged at a left-right interval with the cold rolling wheel set in the first channel on the left; specifically, the multiple channels of the cold rolling wheel set 30 include the first cold rolling wheel set 301, the second cold rolling wheel set 302, the third cold rolling wheel set 303, the fourth cold rolling wheel set 304, the fifth cold rolling wheel set 305, the sixth cold rolling wheel set 306, the seventh cold rolling wheel set 307, the eighth cold rolling wheel set 308, the ninth cold rolling wheel set 309, and the tenth cold rolling wheel set 310, which are sequentially arranged at intervals from left to right; the stamping device 20 is located on the left side of the first cold rolling wheel set 301, and the driving unit 40 is connected to the second cold rolling wheel set 302 and the ninth cold rolling wheel set 309.

[0055] During operation, the steel is conveyed from the left side to the right side of the production line; first, the stamping device 20 performs stamping and forming on the steel to form a special-shaped structure, and then the first cold rolling wheel set 301 to the tenth cold rolling wheel set 310 perform bending operations on the steel to obtain the DTS bracket body; compared with the prior art, the steel is first formed into a special-shaped structure and then bent, which can avoid the force generated by the stamping device 20 from causing the bending angle of the DTS bracket body to not meet the design requirements, thereby improving the bending production yield of the DTS bracket body; moreover, the driving unit 40 is connected to the second cold rolling wheel set 302 and the ninth cold rolling wheel set 309, making the third cold rolling wheel set 303 to the eighth cold rolling wheel set 308 perform non-powered cold rolling operations.

[0060] Please refer to Figure 6 As shown, specifically, the first bending concave part 321 is a planar groove, and the surface of the first upper cold rolling wheel 3011 is a circular surface. The steel material stamped with a special-shaped structure passes through the first upper cold rolling wheel 3011 and the first lower cold rolling wheel 3012, and the special-shaped structure is placed in the first bending concave part 321, so as to adjust the distance between the top of the special-shaped structure and the steel material; compared with the prior art, after the steel material is stamped into a special-shaped structure, the surfaces of the steel material are leveled by the first upper cold rolling wheel 3011 and the first lower cold rolling wheel 3012, and the distance between the special-shaped structure and the steel material is adjusted by the first bending concave part 321, so as to be conducive to ensuring that after the final formed DTS bracket body, the special-shaped structure meets the design requirements and there is no need to trim the special-shaped structure again, thus improving the production efficiency.

[0062] Please refer to Figure 7 As shown, the fourth bending convex portion 326 is a V-shaped protrusion with two inclined surfaces, and the inclination angle A5 between the two inclined surfaces of the fourth bending convex portion 326 is 150 degrees; the fourth bending concave portion 327 is a V-shaped groove with two inclined surfaces, and the inclination angle A6 between the two inclined surfaces of the fourth bending concave portion 327 is 150 degrees. The fifth bending convex portion 328 is a V-shaped protrusion with two inclined surfaces, and the inclination angle A7 between the two inclined surfaces of the fifth bending convex portion 328 is 140 degrees; the fifth bending concave portion 329 is a V-shaped groove with two inclined surfaces, and the inclination angle A8 between the two inclined surfaces of the fifth bending concave portion 329 is 140 degrees. The sixth bending convex portion 3210 is a V-shaped protrusion with two inclined surfaces, and the inclination angle A9 between the two inclined surfaces of the sixth bending convex portion 3210 is 130 degrees; the sixth bending concave portion 3211 is a V-shaped groove with two inclined surfaces, and the inclination angle A10 between the two inclined surfaces of the sixth bending concave portion 3211 is 130 degrees.

[0063] Please refer to Figure 8 As shown, the seventh bending convex portion 3212 is a V-shaped protrusion with two inclined surfaces, and the inclination angle A11 between the two inclined surfaces of the seventh bending convex portion 3212 is 120 degrees; the seventh bending concave portion 3213 is a V-shaped groove with two inclined surfaces, and the inclination angle A12 between the two inclined surfaces of the seventh bending concave portion 3213 is 120 degrees. The eighth bending convex portion 3214 is a V-shaped protrusion with two inclined surfaces, and the inclination angle A13 between the two inclined surfaces of the eighth bending convex portion 3214 is 110 degrees; the eighth bending concave portion 3215 is a V-shaped groove with two inclined surfaces, and the inclination angle A14 between the two inclined surfaces of the eighth bending concave portion 3215 is 110 degrees.

[0064] Please refer to Figure 9As shown, the tenth bending convex part 3218 is a V-shaped protrusion with two inclined surfaces. The inclined angle A17 between the two inclined surfaces of the tenth bending convex part 3218 is 86 degrees; the tenth bending concave part 3219 is a V-shaped groove with two inclined surfaces, and the inclined angle A18 between the two inclined surfaces of the tenth bending concave part 3219 is 86 degrees. Specifically, starting from the second cold rolling wheel set 302 bending the steel to 170 degrees, then between the third cold rolling wheel set 303 and the ninth cold rolling wheel set 309, each time passing through a cold rolling wheel set, the steel is bent and reduced by 10 degrees; finally, through the tenth cold rolling wheel set 310, the steel is bent to 86 degrees, reserving 4 degrees for the springback of the steel, so that the DTS bracket 50 body is finally bent at 90 degrees.

[0065] During actual production, the width of the steel used for DTS brackets of different sizes also changes, which leads to changes in the bending positions of the DTS brackets. This bending position refers to a specific position of the steel from left to right. When dealing with different bending positions, it is necessary to correspondingly change the positions of the cold rolling wheel sets so that the cold rolling wheel sets can bend the steel at different positions; however, the existing method for adjusting the positions of the cold rolling wheel sets is usually that the operator pushes the cold rolling wheel to displace relative to the rotating shaft, thereby changing the position of the cold rolling wheel; this adjustment method makes it difficult to align the bending acting parts 32 of multiple cold rolling wheel sets on the same straight line. Once the bending acting parts 32 of multiple cold rolling wheel sets are not on the same straight line, problems such as skewness in the bending forming of the DTS bracket, non-compliance of the bending angle and surface flatness requirements will occur, resulting in a low production yield of the DTS bracket; therefore, in the embodiments of the present application, the structure of each cold rolling wheel is also improved to solve the above problems.

[0066] Specifically, please refer to Figures 1 to 5 As shown, each cold rolling wheel includes a wheel body 31, a right-handed screw 33 connected to the wheel body 31, and a left-handed screw 34; on one side of the wheel body 31, there is a right-handed internal thread hole 311 for one end of the right-handed screw 33 to be screwed in, and on the other side, there is a left-handed internal thread hole 312 for one end of the left-handed screw 34 to be screwed in. The other ends of the right-handed screw 33 and the left-handed screw 34 are respectively rotatably installed on the base 10; the driving unit 40 is connected to the right-handed screw 33. When the driving unit 40 drives the right-handed screw 33 to rotate, the right-handed screw 33 drives the wheel body 31 and the left-handed screw 34 to rotate synchronously in the rotation direction of the right-handed screw 33; when the right-handed screw 33 rotates forward, the right-handed screw 33 drives the left-handed screw 34 to rotate in reverse to drive the wheel body 31 to displace; or, when the right-handed screw 33 rotates in reverse, the right-handed screw 33 drives the left-handed screw 34 to rotate forward to drive the wheel body 31 to displace.

[0067] Continuing, in the embodiment of the present application, there is also a connection structure 35 for connecting the forward rotation screw 33 and the reverse rotation screw 34. The connection structure 35 includes a horizontal shaft 351 connecting the forward rotation screw 33 and the reverse rotation screw 34, a vertical shaft 352 vertically connected to the middle of the horizontal shaft 351, a first bevel gear 353 fixedly installed on the vertical shaft 352, a second bevel gear 354 fixedly installed on the forward rotation screw 33 and meshing with the first bevel gear 353, and a third bevel gear 355 fixedly installed on the reverse rotation screw 34 and meshing with the first bevel gear 353.

[0068] Specifically, one end of the forward rotation screw 33 is provided with a first mounting post 331 for mounting the second bevel gear 354, and one end of the reverse rotation screw 34 is provided with a second mounting post 341 for mounting the third bevel gear 355; a first mounting shaft hole 332 is recessed on the side surface of the first mounting post 331 opposite to the second mounting post 341, and a second mounting shaft hole 342 is recessed on the side surface of the second mounting post 341 opposite to the first mounting post 331; the diameter of the horizontal shaft 351 is smaller than the diameters of the first mounting shaft hole 332 and the second mounting shaft hole 342. One end of the horizontal shaft 351 is inserted into the first mounting shaft hole 332, and the other end is inserted into the second mounting shaft hole 342; by inserting one end of the horizontal shaft 351 into the forward rotation screw 33 and the other end into the reverse rotation screw 34, the connection strength of the forward rotation screw 33 and the reverse rotation screw 34 can be improved, and the coaxiality of the forward rotation screw 33 and the reverse rotation screw 34 can be ensured, providing a reliable support for the rotation of the cold rolling wheel.

[0069] Moreover, a limiting screw 314 is rotatably installed on the side surface of the wheel body 31. The bottom of the limiting screw 314 is pivotally connected to a limiting block 315, and the bottom of the limiting block 315 is provided with limiting teeth 3151 adapted to the forward rotation screw 33 and the reverse rotation screw 34.

[0070] Continuing, the wheel body 31 further includes a first installation chamber 313 for providing clearance for the connection structure 35. The first installation chamber 313 is located between the forward rotation internal thread hole 311 and the reverse rotation internal thread hole 312. One end of the first installation chamber 313 communicates with the forward rotation internal thread hole 311, and the other end communicates with the reverse rotation internal thread hole 312.

[0071] When adjusting the position of the adjusting wheel body 31, the positive rotation screw 33 can be rotated forward. Through the second bevel gear 354, the first bevel gear 353, and the third bevel gear 355, the reverse rotation screw 34 is driven to rotate in reverse. The forward rotation of the positive rotation screw 33 and the reverse rotation of the reverse rotation screw 34 drive the displacement of the wheel body 31 to realize the specific position adjustment of the adjusting wheel body 31. Of course, rotating the positive rotation screw 33 in reverse can also adjust the position of the adjusting wheel body 31, and the position of the adjusting wheel body 31 can also be adjusted by rotating the reverse rotation screw 34 forward or in reverse. During the operation of the cold rolling wheel, the rotation limit screw 314 is displaced, so that the limit teeth 3151 at the bottom of the limit block 315 abut against the threads of the positive rotation screw 33 and the reverse rotation screw 34, thereby fixing the wheel body 31 to the positive rotation screw 33 and the reverse rotation screw 34. By providing power to the positive rotation screw 33 through the driving unit 40, the cold rolling wheel can be driven to rotate to bend the steel.

[0072] The driving unit 40 includes a first motor 41, a first reduction gear 42, and a second reduction gear 43. The first motor 41 is respectively connected to the first reduction gear 42 and the second reduction gear 43. The first reduction gear 42 is connected to the positive rotation screw 33 of the second cold rolling wheel group 302, and the second reduction gear 43 is connected to the positive rotation screw 33 of the ninth cold rolling wheel group 309. In the embodiment of the present application, the first motor 41 includes a first output end 411 and a second output end 412. The first reduction gear 42 has at least two transmission shafts. One transmission shaft is connected to the first output end 411 through a first transmission rod 421, and the other transmission shaft is connected to the positive rotation screw 33 of the second cold rolling wheel group 302. The second reduction gear 43 has at least two transmission shafts. One transmission shaft is connected to the second output end 412 through a second transmission rod 431, and the other transmission shaft is connected to the positive rotation screw 33 of the ninth cold rolling wheel group 309.

[0073] The base 10 is provided with two fixed plates 11 arranged at intervals front and back. The two fixed plates 11 are provided with bearings (not shown in the figure) for the positive rotation screw 33 and the reverse rotation screw 34 to rotatably insert. The other end of the positive rotation screw 33 is provided with a third mounting post 333 for inserting into the inner ring of the bearing, and the other end of the reverse rotation screw 34 is provided with a fourth mounting post 343 for inserting into the inner ring of the bearing.

[0074] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
