Description

Technical Field

[0001] The invention relates to the technical field of steel bar straightening, and in particular to an auxiliary die for steel bar straightening. Background Art

[0002] In the field of metal processing and manufacturing, steel bars are a common raw material widely used in many industries such as construction, machinery, and automobiles. However, during the production and transportation process, steel bars often bend or twist for various reasons, which not only affects its aesthetics, but more importantly, may reduce the structural strength and service life of the material. Therefore, straightening steel bars has become one of the important steps to improve product quality.

[0003] Traditional steel bar straightening methods mainly include mechanical pressure method, heat treatment method, etc. Among them, the mechanical pressure method changes the shape of the steel by applying external force. Although it is highly efficient, it is easy to cause internal stress concentration; while the heat treatment method softens the steel by heating and then cools it to achieve the purpose of straightening. Although this method can effectively eliminate internal stress, it consumes a lot of energy and has a long cycle. In addition, these traditional methods have poor adaptability to steel bars of different specifications and sizes, and it is difficult to meet diverse needs.

[0004] Existing steel bar straightening devices, such as Chinese patent application CN202420856261.2, disclose a straightening mechanism for stainless steel bar processing, including a bottom plate, a vertical plate 1, a vertical plate 2 and a positioning block are slidably installed on the top of the bottom plate, multiple sets of straightening rollers 2 are rotatably installed on the inner side of the vertical plate 1, multiple sets of straightening rollers 1 are rotatably installed on the inner side of the vertical plate 2, racks are fixedly installed on one end of the inner side of the vertical plate 1 and the vertical plate 2, a rotating rod is rotatably installed inside the positioning block, a rotating handle 2 is fixedly installed on one end of the rotating rod, a gear is fixedly installed on the other end of the rotating rod, and the gear is meshed with the rack. Although it can straighten the steel bar, it only straightens the steel bar by mechanically applying external force, which easily causes internal stress concentration.

[0005] Therefore, a kind of auxiliary die for steel bar straightening is needed to solve the above problems. Summary of the invention

[0006] In order to solve the above problem, that is, to solve the problem that straightening a steel bar by mechanically applying an external force easily leads to internal stress concentration, the present invention provides an auxiliary die for straightening a steel bar.

[0008] Preferably, the straightening mechanism also includes a processing piece arranged in the straightening cylinder, the processing piece includes an annular mounting groove opened on the inner wall of the straightening hole, the inner wall of the mounting groove is fixedly connected with an annular electromagnetic slide rail, two electromagnetic sliders are symmetrically slidably connected in the electromagnetic slide rail, the two electromagnetic sliders are commonly fixedly connected with a processing ring, the inner ring surface of the processing ring is fixedly connected with a processing iron brush, and the processing iron brush can contact the outer circumferential surface of the steel rod.

[0009] Specifically, during use, when the steel rod is straightened, after the heating element heats part of the steel rod, the heated part enters the installation groove during the movement of the straightening cylinder, and the electromagnetic slide rail is started, so that the two electromagnetic sliders in the electromagnetic slide rail slide in the electromagnetic slide rail, and the two electromagnetic sliders drive the processing ring to rotate, and the processing ring drives the processing iron brush to scrape the surface of the steel rod, thereby processing the oxide layer on the surface of the steel rod.

[0010] By setting the processing part, after the steel rod is heated by the heating part, the oxide layer on the surface of the steel rod can be processed by rotating the processing iron brush, thereby reducing the oxide layer on the surface of the steel rod and improving the quality of the steel rod. In addition, by setting the heating part, the oxide layer on the surface of the steel rod can be more easily separated from the steel rod body, which facilitates the processing of the oxide layer by the processing part.

[0011] Furthermore, the electromagnetic slide rail and the electromagnetic slider are prior art and will not be described in detail.

[0012] Preferably, a post-processing part is provided in the straightening cylinder, and the post-processing part is arranged on the side of the processing part away from the heating part.

The through holes are located on the side of the sliding plate close to the heating part.

[0013] Specifically, when in use, after the processing piece processes the oxide layer on the surface of the steel rod, the processed iron filings adhere to the surface of the steel rod, and the sliding plate slides, and the sliding plate moves away from the heating piece, so that a negative pressure is generated in the cavity on the side of the sliding plate close to the heating piece, thereby causing the through hole to absorb air and suck the iron filings processed by the processing piece into the cavity.

[0014] Through the setting of the post-processing part, negative pressure can be generated in the cavity through the sliding of the sliding plate, so that the through hole can be ventilated, so that the iron filings after the oxide layer is processed by the processing part are sucked into the cavity, avoiding the iron filings from adhering to the steel rod and affecting the quality of the straightened steel rod.

[0015] Preferably, the post-processing component also includes a one-way air intake valve arranged in each of the through holes, the bottom surface of the straightening cylinder is fixedly connected to a collecting box, the bottom wall of the cavity is connected to a discharge hole, the discharge hole is connected to the collecting box, a one-way exhaust valve is arranged in the discharge hole, and a filter is arranged on the side of the collecting box.

[0016] Specifically, during use, when the sliding plate moves away from the heating element, external air enters the through hole through the one-way air inlet valve, bringing the iron filings into the cavity; when the sliding plate is reset in the direction close to the heating element, the sliding plate presses the gas in the cavity into the collection box through the one-way exhaust valve, bringing the iron filings in the cavity into the collection box.

[0017] By setting up the collecting box, the iron filings in the cavity can be reset through the sliding plate, and enter the collecting box through the discharge hole with the flow of air and the gravity of the iron filings themselves, thereby preventing the iron filings from accumulating and remaining in the cavity.

[0020] Specifically, during use, when the sliding plate moves away from the heating element, the sliding plate compresses the first spring, and the sliding plate presses the gas in the cavity into the connecting groove. The gas enters the cooling pipe through the connecting groove and is blown onto the outer circumferential surface of the steel rod through the air holes on the cooling pipe, thereby cooling the steel rod to a certain extent.

[0021] By setting the cooling part, the gas in the cavity can be pressed out by the sliding of the sliding plate, so that the gas hangs on the surface of the straightened steel rod, and the surface of the steel rod is cooled to a certain extent, which is convenient for the subsequent use of the steel rod.

[0023] Specifically, during use, when the straightening cylinder moves, the straightening cylinder drives the sliding rod and the abutment rod to move. When the abutment rod abuts against the abutment block, the abutment rod is blocked by the abutment block, and the abutment rod drives the sliding rod to move in the direction away from the heating element. The sliding rod drives the sliding plate to move through the magnetic force, thereby allowing the post-processing element to inhale air. When the sliding plate compresses the first spring to the limit, the sliding plate cannot continue to move, and the abutment rod deflects under the blocking action of the abutment block and accumulates force in the torsion spring. When the abutment rod is detached from the abutment block, the abutment rod is reset under the action of the torsion spring, and then continues to abut against the subsequent abutment block.

[0024] By setting the moving part, the abutment rod can be driven to move during the movement of the straightening cylinder, thereby moving the sliding plate, so that the post-processing part and the cooling part can perform post-processing and cooling work.

DETAILED DESCRIPTION

[0052] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0053] like Figure 1 , 2 As shown in Figures 3 and 4, an embodiment of the present invention discloses an auxiliary mold for straightening a steel rod, comprising a base 1, wherein clamping mechanisms 2 are arranged at both ends of the base 1, wherein the clamping mechanism 2 comprises a fixed clamping member 21 arranged at one end of the base 1, and a sliding clamping member 22 is slidably arranged at the other end of the base 1, wherein the sliding clamping member 22 and the fixed clamping member 21 clamp the two ends of the steel rod respectively, and a straightening mechanism 3 is arranged between the fixed clamping member 21 and the sliding clamping member 22, wherein the straightening mechanism 3 is slidably connected to the base 1, and wherein the straightening mechanism 3 comprises a cylindrical straightening cylinder 31, wherein a straightening hole 32 is penetrated by the straightening cylinder 31, and wherein the steel rod penetrates the straightening hole 32, and wherein a heating member 33 is arranged at one end of the straightening cylinder 31 close to the sliding clamping member 22, and wherein the steel rod penetrates the heating member 33.

[0054] Specifically, in the initial state, the straightening cylinder 31 is located on a side close to the fixed clamp 21, and the straightening cylinder 31 is in contact with the fixed clamp 21; when in use, one end of the steel rod is inserted into the fixed clamp 21, so that the fixed clamp 21 fixes one end of the steel rod, and at the same time the steel rod is inserted into the straightening hole 32 and passes through the heating element 33, and then the sliding clamp 22 is slid so that the sliding clamp 22 contacts the other end of the steel rod and applies a force to the steel rod in the direction of the fixed clamp 21, and then the heating element 33 is started, and the straightening cylinder 31 is slid so that the straightening cylinder 31 moves in a direction close to the sliding clamp 22, so that the heating element 33 first heats the steel rod, and then during the movement of the straightening cylinder 31, the inner wall of the straightening hole 32 straightens the portion of the steel rod heated by the heating element 33, and accordingly the heating element 33 continuously heats the portion of the steel rod, and the straightening hole 32 continuously straightens the heated portion.

[0055] Through the setting of the clamping mechanism 2, the fixed clamping member 21 can fix one end of the steel rod, and the sliding clamping member 22 can fix the other end of the steel rod. The fixed clamping member 21 cooperates with the sliding clamping member 22 to clamp and fix the steel rod, and through the sliding setting of the sliding clamping member 22 and the base 1, the sliding clamping member 22 can slide on the base 1 to clamp steel rods with different curvatures, thereby improving the applicability of the device; through the setting of the heating member 33, it is possible to cooperate with the movement of the straightening cylinder 31, and first heat part of the steel rod before straightening, and through the setting of the straightening hole 32, the heated steel rod part can be straightened, which can reduce stress concentration and improve the quality of the straightened steel rod compared to simple mechanical external force straightening.

[0056] like Figure 3 , 6 As shown in Figures 9 and 10, the straightening mechanism 3 also includes a processing piece 34 arranged in the straightening cylinder 31, and the processing piece 34 includes an annular mounting groove 341 opened on the inner wall of the straightening hole 32, and the inner wall of the mounting groove 341 is fixedly connected with an annular electromagnetic slide rail 342, and two electromagnetic sliders 343 are symmetrically slidably connected in the electromagnetic slide rail 342, and the two electromagnetic sliders 343 are commonly fixedly connected with a processing ring 344, and the inner ring surface of the processing ring 344 is fixedly connected with a processing iron brush 345, and the processing iron brush 345 can contact with the outer circumferential surface of the steel rod.

[0057] Specifically, during use, when the steel rod is straightened, after the heating element 33 heats part of the steel rod, the heated part enters the mounting groove 341 during the movement of the straightening cylinder 31, and the electromagnetic slide rail 342 is started, so that the two electromagnetic sliders 343 in the electromagnetic slide rail 342 slide in the electromagnetic slide rail 342, and the two electromagnetic sliders 343 drive the processing ring 344 to rotate, and the processing ring 344 drives the processing iron brush 345 to scrape the surface of the steel rod, so as to process the oxide layer on the surface of the steel rod.

[0058] By setting the processing part 34, after the steel rod is heated by the heating part 33, the oxide layer on the surface of the steel rod can be processed by rotating the processing iron brush 345, thereby reducing the oxide layer on the surface of the steel rod and improving the quality of the steel rod. In addition, by setting the heating part 33, the oxide layer on the surface of the steel rod can be more easily separated from the steel rod body, which facilitates the processing of the oxide layer by the processing part 34.

[0059] Furthermore, the electromagnetic slide rail 342 and the electromagnetic slider 343 are prior art and will not be described in detail.

[0060] like Figure 3 , 6As shown in Figure 10, a post-processing component 35 is provided in the straightening cylinder 31. The post-processing component 35 is arranged on the side of the processing component 34 away from the heating component 33. The post-processing component 35 includes an annular cavity 351 opened in the straightening cylinder 31. A sliding plate 352 is slidably connected in the cavity 351. Twelve through holes 353 are evenly opened on the inner wall of the cavity 351 along the circumferential direction. The through holes 353 are located on the side of the sliding plate 352 close to the heating component 33.

[0061] Specifically, when in use, after the processing member 34 processes the oxide layer on the surface of the steel rod, the processed iron filings adhere to the surface of the steel rod, and the sliding plate 352 slides, and the sliding plate 352 moves in the direction away from the heating member 33, so that the cavity 351 on the side of the sliding plate 352 close to the heating member 33 generates a negative pressure, so that the through hole 353 inhales air, and the iron filings processed by the processing member 34 are sucked into the cavity 351.

[0062] By setting the post-processing part 35, negative pressure can be generated in the cavity 351 through the sliding of the sliding plate 352, so that the through hole 353 can be ventilated, so that the iron filings after the oxide layer is processed by the processing part 34 are sucked into the cavity 351, avoiding the iron filings from adhering to the steel rod and affecting the quality of the straightened steel rod.

[0063] like Figure 6 As shown, the post-processing component 35 also includes a one-way air intake valve 354 arranged in each of the through holes 353, the bottom surface of the straightening cylinder 31 is fixedly connected with a collecting box 355, the bottom wall of the cavity 351 is connected with a discharge hole 356, the discharge hole 356 is connected with the collecting box 355, a one-way exhaust valve 357 is arranged in the discharge hole 356, and a filter screen 358 is arranged on the side of the collecting box 355.

[0064] Specifically, during use, when the sliding plate 352 moves in a direction away from the heating element 33, external air enters the through hole 353 through the one-way air inlet valve 354, bringing the iron filings into the cavity 351; when the sliding plate 352 is reset in a direction close to the heating element 33, the sliding plate 352 presses the gas in the cavity 351 to enter the collection box 355 through the one-way exhaust valve 357, bringing the iron filings in the cavity 351 into the collection box 355.

[0065] By setting the collecting box 355, the iron filings in the cavity 351 can be reset through the sliding plate 352, and enter the collecting box 355 through the discharge hole 356 with the flow of air and the gravity of the iron filings themselves, thereby preventing the iron filings from accumulating and remaining in the cavity 351.

[0066] Furthermore, the one-way intake valve 354 and the one-way exhaust valve 357 are prior art and will not be described in detail.

[0067] like Figure 3 , 6 As shown, the cavity 351 is connected to a cooling member 36, and the cooling member 36 includes a first spring 361 arranged between the sliding plate 352 and the inner wall of the cavity 351. A side of the straightening cylinder 31 away from the heating member 33 is fixedly connected with an annular cooling pipe 362, and the inner ring surface of the cooling pipe 362 is evenly provided with twenty air holes 363 along the circumferential direction. A side wall of the cavity 351 away from the heating member 33 is connected to a connecting groove 364, and the connecting groove 364 is connected to the cooling pipe 362.

[0068] Specifically, during use, when the sliding plate 352 moves in a direction away from the heating element 33, the sliding plate 352 compresses the first spring 361, and the sliding plate 352 presses the gas in the cavity 351 into the connecting groove 364. The gas enters the cooling pipe 362 through the connecting groove 364, and is blown onto the outer circumferential surface of the steel rod through the air holes 363 on the cooling pipe 362, thereby cooling the steel rod to a certain extent.

[0069] By setting the cooling member 36, the gas in the cavity 351 can be pressed out by the sliding of the sliding plate 352, so that the gas hangs on the surface of the straightened steel rod, and the surface of the steel rod is cooled to a certain extent, which is convenient for the subsequent use of the steel rod.

[0070] like Figure 4 , 7 As shown in Figures 8, 9 and 11, a movable member 37 is provided on the straightening cylinder 31 and the base 1, and the movable member 37 includes two sliding rods 371 symmetrically and slidingly arranged on the outer circumference of the straightening cylinder 31, and the sliding rods 371 are magnetically attracted to the sliding plate 352. Each of the sliding rods 371 is rotatably connected with an abutment rod 372, and a torsion spring 373 is provided at the rotational connection between the abutment rod 372 and the sliding rod 371, and a plurality of abutment blocks 374 are fixedly connected to the base 1 at equal intervals along the length direction, and the bottom end of the abutment rod 372 can abut against the abutment block 374.

[0071] Specifically, during use, when the straightening cylinder 31 moves, the straightening cylinder 31 drives the sliding rod 371 and the abutting rod 372 to move. When the abutting rod 372 abuts against the abutting block 374, the abutting rod 372 is blocked by the abutting block 374, and the abutting rod 372 drives the sliding rod 371 to move in the direction away from the heating element 33. The sliding rod 371 drives the sliding plate 352 to move through the magnetic force, so that the post-processing element 35 can inhale. When the sliding plate 352 compresses the first spring 361 to the limit, the sliding plate 352 cannot continue to move. The abutting rod 372 is deflected under the blocking action of the abutting block 374 and accumulates force for the torsion spring 373. When the abutting rod 372 is detached from the abutting block 374, the abutting rod 372 is reset under the action of the torsion spring 373, and then continues to abut against the subsequent abutting block 374.

[0072] By setting the moving member 37, the abutment rod 372 can be driven to move during the movement of the straightening cylinder 31, so that the sliding plate 352 moves, and the post-processing member 35 and the cooling member 36 perform post-processing and cooling work.

[0074] Specifically, during use, when the moving rod 371 moves, the moving rod 371 drives the telescopic end of the telescopic rod 375 to move.

[0075] By disposing the telescopic rod 375 , the sliding rod 371 can be installed, which facilitates the sliding of the sliding rod 371 .

[0077] Specifically, when in use, when the straightening cylinder 31 needs to be moved, the motor 381 is started, and the output end of the motor 381 drives the lead screw 382 to rotate. The rotation of the lead screw 382 causes the threaded block 383 to move, and the threaded block 383 drives the straightening cylinder 31 to move.

[0078] By setting the moving part 38, the straightening cylinder 31 can be driven to move by the rotation of the motor 381, so as to straighten the steel rod.

[0079] like Figure 3 , 4 As shown, the fixed clamping member 21 includes a fixed cylinder fixedly connected to the base 1 , and a clamping hole opening toward the sliding clamping member 22 is formed in the fixed cylinder.

[0080] By setting the clamping hole, the end of the steel rod can be inserted into the clamping hole to abut and fix the end of the steel rod.
