If "first" and "second" are described, they are only used to distinguish technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0032] In the description of the present application, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present application in combination with the specific content of the technical solution.

[0033] Refer to Figures 1 to 10 , the embodiment of the present application provides a tooling structure for rolling two-way straightness correction, which can quickly switch the straightness correction of different types of products on the same operation platform. Specifically, the tooling structure for rolling two-way straightness correction of the present application includes a mounting base 110, a mounting frame 120, a correction die 130, a first straightness correction fixture 300, and a second straightness correction fixture 200. The mounting frame 120 is rotatably arranged on the mounting base 110, and a limiting structure for restricting the rotation of the mounting frame 120 is arranged between the mounting frame 120 and the mounting base 110. The correction die 130 is arranged on the mounting frame 120. The correction die 130 has an avoidance hole penetrating through both ends. The first straightness correction fixture 300 is detachably installed at one end of the avoidance hole, and the first straightness correction fixture 300 is used for straightness correction of flat arch-shaped products 400. The second straightness correction fixture 200 is detachably installed at the other end of the avoidance hole, and the second straightness correction fixture 200 is used for straightness correction of U-shaped right-angle products 500.

[0034] Among them, the first straightness correction fixture 300 has a correction groove 301 similar to the outer shape of the flat arch-shaped product 400, so that the flat arch-shaped product 400 passing through the correction groove 301 can be effectively corrected.

[0035] In the embodiment of the present application, as Figures 7 to 11As shown in the figure, a rotating shaft 170 is provided in the middle of the top surface of the mounting base 110. The mounting bracket 120 is inserted into the rotating shaft 170 so that the mounting bracket 120 can rotate. A number of rolling balls 160 are arranged in a circumferential array around the rotating shaft 170. The rolling balls 160 are close to the edge of the mounting base 110. The rolling balls 160 are located between the mounting bracket 120 and the mounting base 110, and a groove for positioning the rolling balls 160 is provided on the top surface of the mounting base 110. The rotation center of the mounting bracket 120 is positioned by the rotating shaft 170. By adding the rolling balls 160, the contact area between the mounting bracket 120 and the mounting base 110 is reduced, making it easier to rotate the mounting bracket 120. Among them, the rolling balls 160 also play a role in supporting the mounting bracket 120. The setting of the groove can ensure that the rolling balls 160 roll at the specified position and will not roll away from the mounting base 110, ensuring the safety of rotation.

[0036] In some embodiments, two insertable and removable positioning pins 150 are provided at the bottom of the mounting bracket 120. That is, through holes for the positioning pins 150 to pass through are provided at the bottom of the mounting bracket 120. The positioning pins 150 are inserted into the through holes. The positioning pins 150 are symmetrically arranged with the rotating shaft 170 as the center. Corresponding positioning holes for the positioning pins 150 to be inserted are provided on the mounting base 110. The number of the positioning holes is the same as that of the positioning pins 150. The positioning pins 150 and the positioning holes form a limiting structure. When it is necessary to rotate the mounting bracket 120, the two positioning pins 150 are pulled out of the positioning holes, and the mounting bracket 120 can be freely rotated. After the mounting bracket 120 rotates 180°, the positioning pins 150 are inserted into the positioning holes again to restrict the rotation of the mounting bracket 120, and then the straightness correction operation switching of different rolling products can be carried out.

[0037] Specifically, when performing the straightness correction of the flat arch bending product 400, the second straightness correction fixture 200 on the correction mold 130 is removed to avoid affecting the straightness correction of the flat arch bending product 400. Then, the restriction of the limiting structure is released, the positioning pins 150 are pulled out of the mounting bracket 120, and the mounting bracket 120 is rotated so that the required first straightness correction fixture 300 is rotated to the side of the operation platform for the operator to work. Then, after fixing the mounting bracket 120 through the positioning pins 150 and the positioning holes, the straightness correction of the flat arch bending product 400 can be started through the first straightness correction fixture 300. When performing the straightness correction, the flat arch bending product 400 passes through the first straightness correction fixture 300 and then is discharged through the avoidance hole. The avoidance hole can support a part of the product during the straightness correction.

[0038] When straightness correction of U-shaped right-angle products 500 is required, the first straightness correction fixture 300 on the correction die 130 is removed to avoid affecting the straightness correction of U-shaped right-angle products 500. Then, the cooperation between the positioning pin 150 and the positioning hole is released, and the mounting bracket 120 is rotated so that the required second straightness correction fixture 200 rotates to the side of the operation platform for the operator to work. After fixing the mounting bracket 120 through the cooperation between the positioning pin 150 and the positioning hole, straightness correction of U-shaped right-angle products 500 can be started through the second straightness correction fixture 200. When performing straightness correction, the U-shaped right-angle products 500 pass through the second straightness correction fixture 200 and then are discharged through the avoidance hole.

[0039] This application integrates the straightness correction fixtures for U-shaped right-angle products 500 and planar arch-bending products 400 into the same straightness correction tooling. The straightness correction tooling can rotate, and the correction fixtures can be disassembled. When one correction fixture is in use, the other correction fixture can be removed and the required correction fixture can be rotated to the working side without replacing the entire correction tooling. The straightness correction production switching of products is convenient. It only needs to remove the correction fixture that is not needed, then rotate the required correction fixture to the correct position, and fix it through the limiting structure to complete the switching. The entire tooling structure is simple and the operation is also convenient, which can effectively improve production efficiency.

[0040] In some embodiments, the cross-sectional shape of one end of the avoidance hole is the same as the cross-sectional shape of the first straightness correction fixture 300. After the first straightness correction fixture 300 is inserted into the avoidance hole, it is locked by a locking member. By setting the cross-sectional shape of the end of the avoidance hole to be the same as the cross-sectional shape of the first straightness correction fixture 300, it can be avoided that the first straightness correction fixture 300 rotates during use. Of course, the locking member can also prevent the first straightness correction fixture 300 from rotating. The quick disassembly and locking of the first straightness correction fixture 300 are realized through the cooperation of the hole and the locking member.

[0041] Specifically, the locking member is threadedly connected to the correction die 130, and the locking member can enter the avoidance hole to press against the first straightness correction fixture 300. The movement of the first straightness correction fixture 300 relative to the correction die 130 is restricted by the pressing method. Among them, the locking member is a screw, and the outer surface of the correction die 130 has a threaded hole 133 adapted to the screw, and the threaded hole 133 communicates with the avoidance hole. The cross-section of the first straightness correction fixture 300 is preferably a polygon, and among them, the polygon is one of a triangle, a rectangle or other polygons, so that the first straightness correction fixture 300 cannot rotate automatically after being inserted into the avoidance hole.

[0042] In some other embodiments, the end of the correction die 130 has a connection structure, and the second straightness correction fixture 200 is threadedly connected to the connection structure so that the second straightness correction fixture 200 can be quickly disassembled.

[0043] Specifically, the second straightness correction fixture 200 includes a first correction wheel 220 and two second correction wheels 210, and the docking structure includes a first connecting member 131 and a second connecting member 132. The first connecting member 131 is provided in two pieces, and the two first connecting members 131 are arranged at an interval. The second correction wheel 210 is threadedly connected to the first connecting member 131. Specifically, the second correction wheel 210 has a first connecting stud, and the first connecting stud passes through the first connecting member 131 and is locked by a nut; the first correction wheel 220 is threadedly connected to the second connecting member 132. Specifically, the first correction wheel 220 has second connecting studs on both sides, and the second connecting member 132 is provided in two pieces. The first correction wheel 220 is located between the two second connecting members 132, and the second connecting stud passes through the second connecting member 132 and is locked by a nut. In addition, the first correction wheel 220 is located below the second correction wheel 210, and part of the first correction wheel 220 is located between the two second correction wheels 210, so that a correction groove 301 for straightness correction of the U-shaped right-angle product 500 is formed between the second correction wheel 210 and the first correction wheel 220. The straightness correction of the U-shaped right-angle product 500 is achieved through the correction groove 301.

[0044] In some other embodiments, the first connecting member 131 and the second connecting member 132 are both provided with a waisted groove 1311 so that the distance between the first correction wheel 220 and the second correction wheel 210 is adjustable, thereby facilitating the straightness correction of U-shaped right-angle products 500 of different sizes.

[0045] In some other embodiments, the mounting frame 120 is a rectangular frame structure, that is, a receiving cavity is provided in the mounting frame 120, and the correction mold 130 is slidably provided in the receiving cavity. Specifically, the two sides of the correction mold 130 are in contact with the cavity wall of the receiving cavity, and a slide groove 121 is provided on the cavity wall. The two sides of the correction mold 130 have connecting protrusions extending to the slide groove 121, and the correction mold 130 is restricted from leaving the receiving cavity by the cooperation of the connecting protrusions and the slide groove 121. Since the slide groove 121 is designed along the vertical direction, the correction mold 130 can slide in the vertical direction. Further, the mounting frame 120 is threadedly connected with an adjusting rod 140, and the adjusting rod 140 enters the receiving cavity and rotates to connect the correction mold 130. Specifically, the adjusting rod 140 has a rotatable T-shaped block, and the correction mold 130 has a mounting groove 134 for installing the T-shaped block. The correction mold 130 is driven to rise and fall by rotating the adjusting rod 140, so that the height of the correction mold 130 is adjustable to meet the height requirements of different operators.

[0046] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
