Description

Technical Field

[0001] The invention relates to the field of slitting machines, and in particular to an anti-shake locking structure of a stainless steel coil slitting machine. Background Art

[0002] In the production process of stainless steel pipes, the rolled stainless steel strips need to be unwound first, and then the wider steel strips are cut into multiple thin steel strips through a slitting machine, and then the thin steel strips are bent and welded into steel pipes. In the process of slitting the steel strips, the edges on both sides of the wide steel strips will be cut off as edge materials and rolled up. The slitting machine is equipped with upper and lower slitting rollers, and the steel strip passes between the upper and lower slitting rollers. The height of the lower slitting roller is generally fixed, while the height of the upper slitting roller can be adjusted by the lifting seat at its end and the thread of the vertical screw rod. The upper and lower ends of the screw rod are rotatably connected to the base and top seat of the slitting machine respectively, and the base and top seat are connected by bolts.

[0003] However, after the slitting machine has been used for a period of time, the gaps between the components gradually increase due to wear, causing shaking between the screw rod and the base and top seat, thereby causing the upper slitting roller to shake, resulting in uneven cuts on the left and right edges of the steel strip after slitting, which is not conducive to subsequent welding. Summary of the invention

[0011] Beneficial Effects

[0012] Compared with the prior art, the anti-shake locking structure of the stainless steel coil slitting machine of the present invention has the following advantages:

[0013] 1. When the slitting machine has been used for a period of time and there is shaking between the screw, base and top seat, by twisting the locking nut relative to the screw, the top surface of the locking nut is in close contact with the bottom surface of the top seat. The reaction force of the locking nut can be used to fix the base, top seat and screw, thereby reducing the shaking of the three, allowing the upper slitting roller to rotate smoothly and ensuring that the left and right sides of the steel strip are smooth after being slitting.

[0014] 2. When the locking nut is twisted with a wrench, the inner wall of the arc-shaped portion of the wrench cooperates with the outer wall of the locking nut, and the clamping portion of the wrench cooperates with the inner groove of the locking nut, which can reduce the probability of the wrench slipping off the locking nut during operation and improve work efficiency.

[0020] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0021] Example

[0022] The specific embodiments of the present invention are as follows Figures 1 to 3 As shown, an anti-shake locking structure of a stainless steel coil slitting machine includes a base 11 and a top seat of the slitting machine, which are connected by multiple bolts 7. A vertically arranged screw rod 3 is rotatably connected between the base 11 and the top seat, and the screw rod 3 is threadedly connected to a lifting seat at the end of an upper slitting roller 2 on the slitting machine. A locking nut 4 is threadedly connected to the screw rod 3, and the top surface of the locking nut 4 is in close contact with the bottom surface of the top seat.

[0023] In this embodiment, the locking nut 4 is cylindrical, and its outer wall is provided with an inner groove 41. The anti-shake locking structure also includes a wrench 6, which includes a long rod 61, an arc portion 62 and a clamping portion 63 connected in sequence, and the clamping portion 63 protrudes from the inner wall of one end of the arc portion 62. When the locking nut 4 needs to be screwed, the wrench 6 is first moved to the bottom of the locking nut 4, and then the wrench 6 is moved upward so that the inner wall of the arc portion 62 of the wrench 6 is matched with the outer wall of the locking nut 4, and the clamping portion 63 of the wrench 6 is clamped with the inner groove 41 of the locking nut 4. At this time, the locking nut 4 can be rotated relative to the screw 3 by pulling the long rod 61. After tightening the locking nut 4, the reaction force of the locking nut 4 can be used to fix the base 11, the top seat and the screw 3, thereby reducing the shaking of the three, allowing the upper slitting roller 2 to rotate smoothly, and ensuring that the left and right sides of the steel strip are flat after being slid.

[0024] The lifting seat includes a first lifting seat 21 and a second lifting seat 22 which are respectively rotatably connected to the two ends of the slitting roller 2, and the first lifting seat 21 and the second lifting seat 22 are respectively threadedly connected to different screw rods 3. The top seat includes a first top seat 12 and a second top seat 13, which are respectively located directly above the first lifting seat 21 and the second lifting seat 22, and the first top seat 12 and the second top seat 13 are connected to the base 11 through bolts 7. The screw rod 3 of the first lifting seat 21 is rotatably connected to the first top seat 12, and the top surface of the locking nut 4 on the screw rod 3 is in close contact with the bottom surface of the first top seat 12. The screw rod 3 of the second lifting seat 22 is rotatably connected to the second top seat 13, and the top surface of the locking nut 4 on the screw rod 3 is in close contact with the bottom surface of the second top seat 13.

[0025] Vertical slide rails 14 are disposed on both left and right sides of the base 11 , and both the first lifting seat 21 and the second lifting seat 22 are slidably matched with the corresponding vertical slide rails 14 up and down.

[0026] The screw rods 3 of the first top seat 12 and the second top seat 13 are linked by a synchronous rotation drive mechanism 5. In this embodiment, the synchronous rotation drive mechanism 5 includes a first motor 55 and a horizontally arranged synchronous shaft 51, which are linked to each other. The first motor 55 is installed on the second top seat 13. Both ends of the synchronous shaft 51 are rotatably connected to the first top seat 12 and the second top seat 13, respectively. Both ends of the synchronous shaft 51 are connected to a first bevel gear 52, and the upper end of the screw rod 3 is connected to a second bevel gear 53, and the first bevel gear 52 is meshed with the second bevel gear 53. The first bevel gear 52 and the second bevel gear 53 form a staggered axis bevel gear transmission mechanism.

[0027] When the first motor 55 is started, the synchronous shaft 51 is driven to rotate, and the synchronous shaft 51 can drive different screw rods 3 to rotate synchronously through the first bevel gear 52 and the second bevel gear 53. Since the first motor 55 is arranged on the second top seat 13, and the second motor linked with the upper slitting roller 2 is arranged on the second lifting seat 22, two screw rods 3 are threadedly connected to the second lifting seat 22, and the two screw rods 3 are both rotatably connected to the second top seat 13.

[0028] The present invention has been described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
