Technical Field

[0001] The utility model relates to the technical field of cold bending forming machines, in particular to a straightening machine adjusting mechanism for a cold bending forming machine. Background Technique

[0002] A cold bending forming machine is a machine for the plastic processing technology that continuously transversely bends metal strip materials such as coils and strips through a series of sequentially arranged forming rolls to form profiles with specific cross-sections; during the processing of a cold bending forming machine, profiles with defects such as side bending and warping may occur. At this time, sufficient pressure needs to be applied in the opposite direction by a straightening machine to cause permanent plastic deformation.

[0003] Before using a cold bending forming machine, it is necessary to adjust the gap between the fixed forming roll and the movable forming roll according to the thickness of the material. The patent with the publication number CN213763506U discloses a straightening machine adjusting mechanism for a cold bending forming machine, which drives the adjusting cylinder to move up and down by setting two rotatable screws, so as to adjust the position of the upper rotating roll. However, when using this device, it is necessary to rotate the two screws simultaneously, and it is necessary to ensure that the two screws rotate completely synchronously to realize the up and down adjustment of the two adjusting cylinders, which has relatively high requirements for the operation of the operator and is not convenient to adjust; secondly, the roll body of this mechanism is the same as that of the existing forming machine, which is not convenient for quick installation and disassembly, and it is not convenient to replace the roll body with different grooves for different forming requirements. Therefore, further improvement is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a straightening machine adjusting mechanism for a cold bending forming machine.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a straightening machine adjusting mechanism for a cold bending forming machine, including a base, one side of the upper surface of the base is fixed with a column, and the inside of the column is hollow-designed.

[0007] Further, bumps are fixed on the surfaces of the bottom shaft and the top shaft, and strip-shaped grooves for engaging the bumps are formed on the inner side wall of the forming roller.

[0008] Further, the adjusting assembly includes a lead screw located inside the column. The lead screw is rotatably connected to the top wall of the column through a bearing. A slider is rotatably connected to the surface of the lead screw. Connecting rods are fixed on both sides of the slider. Vertical strip-shaped openings are formed on both sides of the top of the column near the connecting rods. The two connecting rods respectively pass through the two strip-shaped openings and are fixedly connected to the inner wall of the sliding sleeve.

The surface of the sliding sleeve 4 is rotatably connected to a top shaft 5 through a bearing. Forming rollers 6 are fixedly sleeved on the surfaces of the bottom shaft 3 and the top shaft 5. An adjusting assembly 10 for driving the sliding sleeve 4 to move up and down is provided inside the column 2. On the upper surface of the base 1 and on the side far from the column 2, a moving assembly 11 is provided, and a support assembly 12 for supporting the bottom shaft 3 and the top shaft 5 is installed at the top of the moving assembly 11.

[0022] On the surfaces of the bottom shaft 3 and the top shaft 5 near one end of the column 2, baffles 7 are fixedly provided. External threads are provided on the surfaces of the bottom shaft 3 and the top shaft 5 far from one end of the column 2, and an internal thread sleeve 8 is rotatably connected to the external thread surface. The forming roller 6 is located between the baffle 7 and the internal thread sleeve 8.

[0023] After slipping the forming roller 6 onto the surface of the bottom shaft 3 or the top shaft 5, an internal thread sleeve 8 can be screwed onto the surfaces of the bottom shaft 3 and the top shaft 5, and the forming roller 6 is fixed by squeezing through the internal thread sleeve 8 and the baffle 7.

[0024] Protrusions 9 are fixed on the surfaces of both the bottom shaft 3 and the top shaft 5, and a strip-shaped groove 61 for engaging the protrusion 9 is provided on the inner side wall of the forming roller 6.

[0025] After the protrusion 9 is engaged in the strip-shaped groove 61, the forming roller 6 can rotate following its corresponding bottom shaft 3 or top shaft 5.

[0026] The adjusting assembly 10 includes a lead screw 101 located inside the column 2. The lead screw 101 is rotatably connected to the top wall of the column 2 through a bearing. A slider 102 is rotatably connected to the surface of the lead screw 101. Connecting rods 103 are fixed on both sides of the slider 102. Vertical strip-shaped openings 21 are provided on both sides of the top of the column 2 near the connecting rods 103. The two connecting rods 103 respectively pass through the two strip-shaped openings 21 and are fixedly connected to the inner wall of the sliding sleeve 4. The top end of the lead screw 101 extends outside the column 2 and is fixedly connected to a knob 104.

[0027] When the lead screw 101 is rotated forward or backward, the lead screw 101 will drive the slider 102 and the connecting rods 103 to move up and down along the strip-shaped opening 21, thereby driving the sliding sleeve 4 to move up and down to adjust the position of the top shaft 5.

[0028] The moving assembly 11 includes a T-shaped guide rail 111 fixed on the upper surface of the base 1. A sliding seat 112 is slidably connected to the surface of the T-shaped guide rail 111. The top wall of the sliding seat 112 penetrates and is threadedly connected with a first locking bolt 113.

[0029] The sliding seat 112 can move along the T-shaped guide rail 111, and the sliding seat 112 can be fixed by tightening the first locking bolt 113.

[0030] The supporting assembly 12 includes a vertical plate 121 fixed on the upper surface of the sliding seat 112. A first support seat 122 is fixed on the surface of the vertical plate 121 and facing one side of the bottom shaft 3. A second support seat 123 is slidably sleeved on the top surface of the vertical plate 121. Axial grooves are provided on one side of the first support seat 122 and the second support seat 123 close to the column 2. A second locking bolt 124 penetrates and is threadedly connected to the side of the second support seat 123 away from the axial groove.

[0031] When it is necessary to adjust the top shaft 5, the sliding seat 112 can be moved first to drive the vertical plate 121 away from the bottom shaft 3 and the top shaft 5. After the position of the top shaft 5 is adjusted, the second support seat 123 can be slid up and down so that the height of the second support seat 123 corresponds to the height of the top shaft 5. Tightening the second locking bolt 124 can fix the second support seat 123. The axial grooves on the first support seat 122 and the second support seat 123 are respectively used for engaging the bottom shaft 3 and the top shaft 5.

[0032] Working principle: When it is necessary to adjust the position of the top shaft 5 or replace the forming rollers 6 on the surfaces of the bottom shaft 3 and the top shaft 5, first move the slide seat 112 to make the vertical plate 121 away from the bottom shaft 3 and the top shaft 5. At this time, the internal thread sleeves 8 on the bottom shaft 3 and the top shaft 5 can be unscrewed, and then the forming roller 6 can be taken away from the surfaces of the bottom shaft 3 and the top shaft 5 and replaced. When it is necessary to adjust the height of the top shaft 5, the screw rod 101 can be driven to rotate by turning the knob 104. The screw rod 101 drives the sliding sleeve 4 to slide up and down to change the height of the top shaft 5. Then, adjust the height of the second support seat 123 to be equal to that of the top shaft 5, and then tighten the second locking bolt 124 to fix the second support seat 123. After the adjustment, move the slide seat 112 closer to the bottom shaft 3 and the top shaft 5 until the bottom shaft 3 and the top shaft 5 are respectively clamped into the shaft grooves on the first support seat 122 and the second support seat 123, and finally tighten the first locking bolt 113 to fix the slide seat 112.
