Description

Technical Field

[0001] This utility model relates to a straightening machine, and more particularly to a straightening device for the straightening machine. Background Technology

[0002] Straightening machines typically straighten workpieces by pressing them with straightening rollers. The straightening rollers are driven by a device to adjust the clamping force and position. For example, Chinese Patent CN 216027229 U discloses a roller gap height adjustment mechanism for a pipe straightening machine. Its drive unit uses a lifting assembly to drive the upper straightening roller seat and the upper straightening roller to move synchronously up and down, adjusting the roller gap height between the upper and lower straightening rollers, thereby adjusting the actual straightening force to the rated straightening force. This mechanism mainly uses a motor and ball screw to adjust the position and pressure of the straightening rollers. However, the high cost of motors and ball screws results in a high overall cost for the straightening equipment. Utility Model Content

Detailed Implementation

[0014] The present invention will now be further described with reference to the accompanying drawings.

[0015] like Figures 1 to 6As shown, a straightening device for a straightening machine includes a straightening base 11, a straightening slider 13, a straightening roller 12, a straightening cylinder 14, a locking cylinder 17, and a locking block 18. The straightening base 11 has a guide hole 111 along its length, which is a through hole. The top of the straightening base 11 has a locking hole 113, which communicates with and is perpendicular to the guide hole 111. The straightening slider 13 is slidably inserted into the guide hole 111. The side of the straightening slider 13 has a locking groove 131. Both ends of the straightening slider 13 are connected to the piston rods of the straightening roller 12 and the locking cylinder 17, respectively. The ends of the straightening roller 12 and the straightening slider 13 are rotatably connected, allowing the straightening roller 12 to rotate freely. The straightening roller 12 is located at one end of the straightening base 11. The straightening cylinder 14 is fixed to the other end of the straightening base 11. The locking cylinder 17 is fixed on the top of the straightening base 11 and located above the locking hole 113. The piston rod of the locking cylinder 17 is connected to the locking block 18. The locking block 18 is movably inserted into the locking hole 113 and is opposite to the locking groove 131. When it is necessary to lock the position of the straightening slider 13 so that the position of the straightening roller 12 remains unchanged for final straightening, the locking cylinder 17 drives the locking block 18 to insert into the locking groove 131, so that the position of the straightening slider 13 remains unchanged, and thus the position of the straightening roller 12 remains unchanged.

[0016] During initial straightening, the workpiece is straightened by the pressure of the cylinder. After repeated straightening, when the straightness of the workpiece is high, a larger pressure is required. Since the position of the straightening roller cannot be changed, the position of the straightening roller 12 is locked by the locking block 18, so that the pressure adjustment cylinder 14 is ineffective.

[0017] The use of a straightening cylinder 14 allows the straightening roller 12 to have greater freedom during the initial straightening of the workpiece, and requires less pressure, making the initial straightening of the workpiece easier. Because the initial deformation of the workpiece is large, the required straightening pressure is small. At this time, by repeatedly rolling with a small straightening pressure, the straightness of the workpiece after final straightening is high. At the same time, it solves the problem that the straightening machine requires a large straightening pressure, reduces the requirements for the overall strength of the straightening machine, reduces equipment costs, and does not affect the straightening efficiency.

[0018] When performing the final straightening, since the deformation angle of the workpiece is very small, a large pressure is required. Therefore, the position of the straightening roller 12 is limited by the locking block 18 and the locking groove 131, eliminating the need for the cylinder to provide the final straightening pressure. This reduces the requirements for the cylinder and allows the use of a smaller cylinder, thus reducing the cost of the cylinder.

[0019] The straightening achieved by using the straightening cylinder 14 to provide constant pressure is the same as the gradual straightening achieved by the motor and ball screw, and the time required is also basically solved, but it can greatly reduce the cost of the equipment and the cost of use.

[0020] To limit the position of the straightening roller 12 and prevent it from rotating axially, the guide hole 111 is a square hole and the straightening slider 13 is a square block. The square hole and the square straightening slider 13 prevent the straightening roller from rotating axially, and also solve the problems of easy mode and low pressure bearing capacity caused by the groove structure set along the length direction of the straightening slider 13 by pin engagement.

[0021] To facilitate the insertion of the locking block 18 into the locking groove 131, the locking groove 131 is a V-shaped groove, and the end of the locking block 18 is tapered and matches the locking groove 131.

[0022] To facilitate observation of the position of the straightening roller 12, the straightening machine's pressing device also includes a scale mark 132, which is set on the pressing slider 13 and is positioned opposite to the end of the pressing base 11.

[0023] To facilitate adjustment of the position of the straightening roller 12 according to different workpieces—for example, workpieces of different diameters require different positions when locking the straightening roller 12, meaning the distance between the straightening rollers 12 on both sides of the workpiece must match the outer diameter of the workpiece—the straightening roller 12 position needs to be adjusted. Therefore, the straightening machine's straightening device also includes a connecting slider 15 and a straightening connecting rod 16. The connecting slider 15 is movably inserted into the guide hole 111. One end of the connecting slider 15 is connected to the straightening cylinder 14, and the other end is connected to one end of the straightening connecting rod 16. The other end of the straightening connecting rod 16 is connected to the straightening slider 13, thus adjusting the position of the straightening roller 12. Furthermore, the straightening connecting rod 16 has a connecting screw 161 and a connecting block 163 at both ends, and a connecting screw hole 151 at one end of the connecting slider 15. The connecting screw 161 and the connecting screw hole 151 are connected by threads to adjust the distance between the connecting slider 15 and the straightening slider 13. The diameter of the connecting block 163 at the end of the straightening connecting rod 16 is larger than the diameter of the straightening connecting rod 16, forming a T-shaped structure. The connecting block 163 is movably inserted into the rotating groove 135 at the end of the straightening slider 13. The rotating groove 135 is a T-shaped groove.

[0024] To facilitate direct adjustment of the straightening connecting rod 16, the straightening base 11 is provided with an adjustment groove 122 communicating with the guide hole 111. The adjustment groove 122 is also positioned opposite to the straightening connecting rod 16. The straightening connecting rod 16 is provided with a tool groove 162, which can be engaged with an open-end wrench to achieve rotation of the straightening connecting rod 16. The tool groove 162 is positioned opposite to the adjustment groove 122. The adjustment groove 122 allows the straightening connecting rod 16 to be adjusted without disassembling the straightening cylinder 14, improving efficiency.

[0025] To facilitate the fixing of the locking cylinder 17, the straightening device of the straightening machine also includes a locking connecting seat 19. The locking connecting seat 19 is fixed to the top of the straightening base 11 and connected to the locking cylinder 17. The locking connecting seat 19 has a through hole inside to facilitate the installation and movement of the locking block 18. Furthermore, to facilitate the observation of the state of the locking block 18, the locking connecting seat 19 is also provided with several locking observation slots 191 for observing the locking block 18.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
