Description

Technical Field

[0001] This utility model belongs to the field of straightening machine technology, and specifically relates to an adjustment device for a straightening machine. Background Technology

[0002] A straightening machine is a device used to correct the shape of metal materials (such as bars, tubes, and profiles). It applies external force to the material, causing it to bend in the opposite direction, thus correcting existing shape defects such as bending or twisting. It typically includes a frame, straightening rollers, a transmission system, and an adjustment device. The adjustment device, used to adjust the position of the straightening rollers, can be hydraulic or mechanical. Mechanical straightening devices usually adjust the gap between the rollers using a screw and nut. Figure 1 The structure shown is that of an existing mechanical pressing device, including a straightening roller 1, a telescopic adjusting cylinder 2 with a nut, an adjusting seat 3, an adjusting screw seat 4, and an adjusting screw 5. The adjusting screw seat 4 is connected to the upper end of the adjusting seat 3. The telescopic adjusting cylinder 2 with a nut is located inside the adjusting seat 3 and is engaged with the adjusting screw 4 via a guide key 9 to form a circumferential linkage and axial sliding engagement. The adjusting screw 5 passes through the adjusting screw seat 4 and is threadedly engaged with the telescopic adjusting cylinder 2 with a nut. The telescopic adjusting cylinder 2 with a nut is fixedly connected to the straightening roller 1. The adjusting seat 3 is fixed to the frame 6. Rotating the adjusting screw 5 drives the telescopic adjusting cylinder 2 with a nut to slide axially. The inventors have discovered that the above-mentioned existing structure has the following problems: During operation, the telescopic adjusting cylinder 2 with a nut is locked in its axial position only by the adjusting screw 5. Due to the gap between the screw and the nut, the telescopic adjusting cylinder 2 with a nut is in a slack state, which causes vibration during operation. This leads to an increasing gap between the telescopic adjusting cylinder 2 with a nut and the adjusting seat 3, ultimately resulting in a significantly shortened lifespan for these two parts. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an adjustment device for a straightening machine.

[0004] The technical solution adopted by this utility model is as follows: An adjustment device for a straightening machine includes a straightening roller, a telescopic adjusting cylinder with a nut, an adjusting seat, and an adjusting screw. The telescopic adjusting cylinder with a nut is located inside the adjusting seat, and the two form a circumferential linkage and axial sliding fit relationship. The adjusting screw is threadedly engaged with the telescopic adjusting cylinder with a nut. The telescopic adjusting cylinder with a nut is fixedly connected to the straightening roller, and the adjusting seat is fixed on the machine frame. A locking disc is sleeved on the outer periphery of the telescopic adjusting cylinder with a nut. The locking disc can tighten / loosen the outer periphery of the telescopic adjusting cylinder with a nut, and the locking disc is fixedly connected to the machine frame.

[0005] The locking disc is a ring-shaped component with a clamping gap on one side. The locking disc is connected to a locking rod for adjusting the size of the clamping gap.

[0006] The locking disc has a through hole and a screw hole on both sides of the clamping gap, and a groove is cut on the side of the through hole away from the clamping gap to form a first abutting step. The screw hole has a thread. The front end of the locking rod has a threaded rod and the rear end of the threaded rod has a second abutting step. The threaded rod passes through the through hole and is threadedly connected to the screw hole. The first abutting step and the second abutting step abut against each other.

[0007] The locking disc has a groove on its inner circumference.

[0008] The groove is located on the opposite side of the clamping gap.

[0009] The locking disc is detachably and fixedly connected to the frame via threaded fasteners.

[0010] The adjusting seat has a flange ring on its outer periphery, and the flange ring has a plurality of first connecting holes. The locking plate has a plurality of second connecting holes. The frame, flange ring, and locking plate are stacked in sequence, and threaded fasteners fix the frame, flange ring, and locking plate together.

[0011] The first connecting hole is an oblong hole, and the second connecting hole is a screw hole.

[0012] The inner wall of the adjusting seat is provided with a keyway arranged along the axial direction, and the outer wall of the telescopic adjusting cylinder with nut is limited to the inner wall of the adjusting seat by a guide key.

[0013] The beneficial effects of this utility model are as follows: By setting a locking disc on the outer periphery of the telescopic adjusting cylinder with nut, when the position of the straightening roller needs to be adjusted, the telescopic adjusting cylinder with nut is loosened, allowing it to move under the drive of the adjusting screw. When the position of the straightening roller does not need to be adjusted, the telescopic adjusting cylinder with nut is locked and its position is locked, preventing vibration of the telescopic adjusting cylinder with nut during operation and improving the service life of the telescopic adjusting cylinder with nut and the adjusting seat.

Detailed Implementation

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0021] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0022] The directional and positional terms used in this utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0023] An adjustment device for a straightening machine, such as Figure 2 The system includes a straightening roller 1, a telescopic adjusting cylinder 2 with a nut, an adjusting seat 3, an adjusting screw seat 4, and an adjusting screw 5. The adjusting screw seat 4 is connected to the upper end of the adjusting seat 3. The telescopic adjusting cylinder 2 with a nut is located inside the adjusting seat 3, and the two form a circumferential linkage and axial sliding fit relationship. The adjusting screw 5 passes through the adjusting screw seat 4 and is threadedly engaged with the telescopic adjusting cylinder 2 with a nut. The telescopic adjusting cylinder 2 with a nut is fixedly connected to the straightening roller 1, and the adjusting seat 3 is fixed to the frame 6. A handwheel is connected to the upper end of the adjusting screw 5. Rotating the adjusting screw 5 drives the telescopic adjusting cylinder 2 with a nut to slide axially within the adjusting seat 3, thereby adjusting the axial position of the straightening roller 1 connected to the lower end of the telescopic adjusting cylinder 2 with a nut.

[0024] A locking disc 7 is fitted around the outer periphery of the telescopic adjusting cylinder 2 with a nut. The locking disc 7 can tighten / loosen the outer periphery of the telescopic adjusting cylinder 2 with a nut, and the locking disc 7 is fixedly connected to the frame 6. When adjustment is needed, the locking disc 7 is released, allowing the telescopic adjusting cylinder 2 with a nut to slide axially. When adjustment is not needed, the locking disc 7 is tightened to lock the relative position of the telescopic adjusting cylinder with a nut to the frame 6, preventing vibration of the telescopic adjusting cylinder with a nut during operation and improving the service life of the telescopic adjusting cylinder with a nut and the adjusting seat.

[0025] Furthermore, such as Figure 3 As shown, the locking disc 7 is an annular component with a clamping gap 701 on one side. The locking disc 7 is connected to a locking rod 705 for adjusting the size of the clamping gap 701. The locking disc 7 can be manually driven or automatically driven by a motor, hydraulic system, or other means.

[0026] Figure 3 The diagram shows a specific structure for manual operation. The locking disc 7 has a through hole 702 and a threaded hole 703 on each side of the clamping gap 701. A groove is cut into the side of the through hole 702 away from the clamping gap 701 to form a first abutting step 704. The threaded hole 703 has a threaded thread. The locking rod 705 has a threaded rod portion 706 at its front end and a second abutting step 707 at its rear end. The threaded rod portion 706 passes through the through hole 702 and is threadedly connected to the threaded hole 703. The first abutting step 704 and the second abutting step 707 abut against each other. By rotating the locking rod 705, the clamping gap 701 can be adjusted, thereby causing the locking disc 7 to tighten / loosen the telescopic adjusting cylinder 2 with a nut.

[0027] Furthermore, the locking disc 7 has a groove 708 on its inner circumference. The overall radial thickness of the locking disc 7 is relatively large, and the groove 708 makes the radial thickness of the locking disc 7 at the location of the groove 708 smaller, providing more elasticity.

[0028] Furthermore, the groove 708 is located on the opposite side of the clamping gap 701.

[0029] Furthermore, the locking disc 7 is detachably and fixedly connected to the frame 6 via threaded fasteners 8. Specifically, the adjusting seat 3 has a flange ring 301 on its outer periphery, the flange ring 301 has several first connecting holes 302, and the locking disc 7 has several corresponding second connecting holes 709. The frame 6, flange ring 301, and locking disc 7 are stacked sequentially, and the threaded fasteners 8 fix the frame 6, flange ring 301, and locking disc 7 together. That is, the threaded fasteners 8 can simultaneously fix the adjusting seat 3 and the locking disc 7 to the frame 6.

[0030] Furthermore, the first connecting hole 302 is an oblong hole, and the second connecting hole 709 is a threaded hole. With the first connecting hole 302 set as an oblong hole, when the threaded fastener 8 is not tightly fitted with the frame 6, flange ring 301, and locking disc 7, it can move within a small range within the oblong hole, allowing the angle of the adjusting seat 3 relative to the frame 6 to be adjusted within a small range. This, in turn, allows the telescopic adjusting cylinder 2 with a nut, which forms a circumferential linkage with the adjusting seat 3, to be adjusted within a small range, thereby achieving the angle adjustment of the straightening roller 1. After the angle adjustment is completed, tightening the threaded fastener 8 to tightly fit the frame 6, flange ring 301, and locking disc 7 completes the angle fixation.

[0031] The inner wall of the adjusting seat 3 is provided with a keyway 303 arranged along the axial direction, and the outer wall of the telescopic adjusting cylinder 2 with nut is limited to the inner wall of the adjusting seat 3 by a guide key 9.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
