[0002] When using workpieces as raw materials to process screws, threaded rods and other workpieces, it is generally necessary to straighten the workpieces. For workpieces with a diameter less than 20mm, manual straightening can be done using a straightening sleeve, but for workpieces with a diameter between 25mm and 40mm, a workpiece straightening machine is required for straightening.

[0003] The Chinese utility model patent with publication date of December 16, 2015 and publication number CN204867201U proposes a workpiece straightening machine, which includes a straightening device seat, an upper straightening wheel group, a lower straightening wheel group, and a lifting device. The upper straightening wheel group and the lower straightening wheel group are respectively provided with a plurality of upper straightening wheels and lower straightening wheels, the lower straightening wheels correspond to the upper straightening wheels and are staggered with each other, the wires are passed through the lower straightening wheels and the upper straightening wheels, and V-shaped grooves are opened on the circumference of the lower straightening wheels and the upper straightening wheels.

[0004] When the workpiece is straightened, the workpiece is placed between the lower straightening wheel and the upper straightening wheel, and the bent workpiece is straightened through the V-shaped grooves of the lower straightening wheel and the upper straightening wheel. However, the workpiece straightening machine can only flatten the workpiece from the upper and lower directions, and cannot straighten the workpiece from other directions, so it is difficult to ensure the straightening quality of the workpiece.

[0007] By adopting the above technical solution, when straightening the workpiece, the spacing between the first support parts is adjusted by the first moving part, and then the workpiece is placed on the roller of the first support part, and the workpiece is supported by the support mechanism. The roller rotates under the action of the roller driving mechanism, and the workpiece rotates with the roller. Then, the position of the gantry bracket is adjusted to align the punch with the workpiece straightening position, and the punch is started to punch and straighten the workpiece. During the straightening process, since the workpiece can rotate with the roller, the punch can apply pressure to the workpiece from all directions, thereby achieving the effect of straightening and improving the surface quality of the workpiece. In addition, during the straightening process, when the workpiece is subjected to a large pressure from the punch, the support mechanism can help disperse the pressure, thereby reducing damage to the workpiece and extending the service life of the workpiece.

[0019] By adopting the above technical solution, when the second pressure head needs to rise, the second cylinder drives the inclined block to move forward, and the inclined block squeezes the second pressure head through the inclined surface at the top, so that the second pressure head rises. When the second pressure head needs to be lowered, it only needs to drive the inclined block backward through the second cylinder.

In addition, in order to increase the friction between the rollers 212 and the workpiece, the outer edge of the rollers 212 can be provided with a rubber ring or the like.

[0044] The first support portion 210 also includes a roller spring box 215, a first pressure head 216 and a first support plate 217. The roller spring box 215 is arranged between the roller 212 and the first substrate 211 and connected to the two. The first pressure head 216 is arranged on the first substrate 211. The first pressure head 216 is a plate-like structure, and the height of the first pressure head 216 is less than the height of the roller 212, so that when the workpiece is placed on the roller 212, the workpiece will not directly contact the first pressure head 216. A card slot is arranged on the top of the first pressure head 216, and the card slot is used to match the workpiece. The first support plate 217 is connected to the bottom of the first substrate 211.

[0045] It should be noted that during the straightening process, the workpiece will be subjected to a large pressure from the punch 410, and this pressure acts on the roller 212 through the workpiece.

[0048] When the workpiece is subjected to a greater pressure from the punch, the first pressure head 216 acts on the first linear rail guide portion 223 through the workpiece and the first substrate 211, and the first spring 2181 can absorb and mitigate the energy caused by vibration or impact, thereby reducing the support burden of the first linear rail guide portion 223 and maintaining the structural stability of the first linear rail guide portion 223.

[0049] The rotating mechanism also includes a pressure wheel portion 230, which includes a first vertical plate 231, a first cylinder 232, a connecting rod 233 and a pressure wheel 234.

[0052] Specifically, a through hole is provided on the first vertical plate 231, and a longitudinally extending strip hole is provided on the second vertical plate 235. The first vertical plate 231 and the second vertical plate 235 are connected by bolts and nuts passing through the through holes and the strip holes. The height of the second vertical plate 235 is adjusted by adjusting the tightness of the bolts and nuts, so that the pressure wheel 234 can clamp workpieces of different diameters, thereby firmly fixing the workpiece and preventing the workpiece from displacement or sliding during the straightening process.

[0053] The support assembly 300 is connected to the frame 100, and the support assembly 300 is used to support the workpiece. The support assembly 300 includes at least two groups of support mechanisms arranged at intervals in the length direction of the frame 100, and the two groups of support mechanisms are located between the two groups of rotating mechanisms; the support mechanism includes a second support portion 310 and a second movable portion 320 connected to the bottom of the second support portion 310, and the second support portion 310 is slidably connected to the frame 100 through the second movable portion 320.

[0056] The second support portion 310 includes a second ram 311, a second substrate 312, a sleeve 313 and a driving portion, wherein the sleeve 313 is connected to the second substrate 312, the second ram 311 is slidably connected to the sleeve 313, the driving portion is arranged on one side of the sleeve 313 and is connected to the second ram 311, the second ram 311 can rise or fall under the action of the driving portion, and a slot is arranged on the top of the second ram 311. The second support portion 310 is mainly used to carry the workpiece, and can also disperse the pressure on the workpiece to reduce damage to the workpiece. In addition, the second ram 311 is in an upright state, and the slot on its top is used to match the workpiece.

[0057] Specifically, the driving part includes an inclined block 314 and a second cylinder 315. The second cylinder 315 is connected to the second base plate 312. The side of the sleeve 313 has an opening, and the opening faces the second cylinder 315. The inclined block 314 is inserted into the hollow part through the opening. The top surface of the inclined block 314 has an inclined surface, and the inclined surface is inclined from the end away from the opening to the direction close to the second cylinder 315. The bottom surface of the second pressure head 311 is against the inclined surface of the inclined block 314, and the two are matched with each other. The inclined block 314 is connected to the second cylinder 315, and the inclined block 314 can move under the action of the second cylinder 315 to raise or lower the second pressure head 311.

[0058] The driving part composed of the inclined block 314 and the second cylinder 315 has a simple structure, high transmission efficiency and low energy loss. It is understandable that when the workpiece is subjected to a large pressure from the punch, the pressure acts directly on the second pressure head 311, and the second pressure head 311 then transmits the pressure to the inclined block 314. Since the second pressure head 311 and the inclined block 314 are in direct contact, a hard contact is formed, thereby providing a more stable support, reducing the vibration and deformation of the mechanical system. Compared with transmission methods such as screws and gears, it is not easy to be damaged and has a simple maintenance method.

[0059] The second support portion 310 also includes a second floating spring box 316. The first floating spring box 316 includes a second spring 3161 and a second spring guide 3162.

The second spring 3161 extends from the bottom of the second spring guide 3162 and passes through the second substrate 312 to be connected to the second linear rail guide portion 323.

[0060] When the workpiece is subjected to greater pressure from the punch, the second pressure head 311 acts on the second linear rail guide portion 323 through the workpiece and the second substrate 312, and the second spring 3161 can absorb and mitigate the energy caused by vibration or impact, thereby reducing the support burden of the second linear rail guide portion 323 and maintaining the structural stability of the second linear rail guide portion 323.

[0061] The impact assembly 400 includes a punch 410 and a gantry bracket 420. The gantry bracket 420 is slidably connected to the frame 100 so that the gantry bracket 420 can move along the length direction of the frame 100. The punch 410 is connected to the gantry bracket 420, and the impact surface of the punch 410 faces the frame 100 so that the punch 410 can impact the workpiece on the support assembly 300 when it falls.

[0062] It should be noted that the gantry support 420 is slidably connected to the frame 100, so that the gantry support 420 and the punch 410 can be moved according to the straightening position of the workpiece. Specifically, the gantry support 420 and the frame 100 can be connected by a gear rack structure. That is, a rack is installed on the inner side or outer side of the frame 100, and a motor and a matching gear are installed at the bottom between the gantry, the gear is meshed with the rack, and the gear is driven to rotate by the motor, thereby driving the gantry support 420 to move.

[0063] On the other hand, an embodiment of the present invention further provides a method for straightening threaded steel, comprising the following steps: S1, providing a rotating mechanism, and placing a workpiece on the rotating mechanism, so that the workpiece rotates on the rotating mechanism. Specifically, the rotating mechanism in the method can be the rotating mechanism in any of the above-mentioned embodiments. S2, providing a supporting mechanism, and moving the supporting mechanism to below the position of the workpiece to be straightened, and making the supporting mechanism abut against the surface of the workpiece, wherein the supporting mechanism in the method can be the supporting mechanism in any of the above-mentioned embodiments. S3, providing an impact assembly, aligning the punch of the impact assembly with the straightening position of the workpiece, and applying pressure to the workpiece under the protection of the shock absorbing mechanism. The impact assembly in the method can be the impact assembly 400 in any of the above-mentioned embodiments, and the shock absorbing mechanism can be the roller spring box 215, the first floating spring box 218, and the second floating spring box 316 in the above-mentioned embodiments.

[0064] By adopting the above technical solution, the rotating mechanism can drive the workpiece to rotate, and the supporting mechanism can provide stable support for the workpiece, so that when the punch applies pressure to the workpiece, since the workpiece can rotate with the rotating mechanism, the punch can apply pressure to the workpiece from all directions, thereby achieving the effect of straightening and improving the surface quality of the workpiece. In addition, the shock absorbing mechanism can also absorb the energy caused by the impact of the rotating mechanism and the supporting mechanism, thereby reducing the supporting burden of the rotating mechanism and the supporting mechanism and maintaining structural stability.

[0065] It should be noted that the straightening machine of the embodiment of the present application can also be used for straightening operations of workpieces such as metal pipes, bars, and wires.

[0066] The implementation principle of the straightening machine in this embodiment is: When straightening workpieces such as wires, pipes or bars, the spacing between the two rotating mechanisms is adjusted according to the length of the workpiece, and the workpiece is placed between the two rollers 212, the first cylinder 232 is started, the pressing wheel 234 is pressed against the surface of the workpiece, and the roller driving mechanism 214 is started, and the roller 212 drives the workpiece to rotate under the action of the synchronous wheel 213. The position of the support mechanism is adjusted to move the second pressing head 311 of the second supporting part 310 below the position of the workpiece to be straightened, and then the position of the gantry bracket 420 is adjusted to move the punch 410 above the position of the workpiece to be straightened, and the punch 410 is started to continuously apply pressure to the surface of the workpiece.

[0067] When straightening a workpiece, a pipe or a bar, the punch 410 acts on the workpiece, and the workpiece is subjected to a large pressure from the punch 410. The pressure acts on the roller 212 through the workpiece, and the roller spring box 215 at the bottom of the roller 212 can absorb and reduce the energy caused by vibration or impact, thereby protecting the roller 212 from damage. In addition, when straightening a workpiece, a pipe or a bar, the second cylinder 315 pushes the inclined block 314 to move, and the inclined block 314 pushes the second pressing head 311 through the inclined surface at the top thereof, so that the second pressing head 311 rises, and then the second pressing head 311 can be pressed against the surface of the workpiece.

[0068] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
