Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of cold rolling reversible rolling mill equipment in the metallurgical industry, and in particular relates to a tool for processing broken thin-gauge strip steel of a reversible cold rolling mill. Background Art
[0002] Thin-gauge products are high-end products rolled by reversible cold rolling mills. The thickness of finished products is generally less than 0.3mm. They are characterized by high hardness, poor plasticity, and high deformation resistance. Once a strip breaks, it is extremely difficult to handle and rethread the broken strip. Since the strip is thin and easy to be shrouded, the normal threading method cannot move the strip head forward and requires tools to pull it to complete the threading operation. The surface of the broken strip has a lot of residual oil and cannot be glued.
[0003] In the prior art, a vise is usually used as a simple tool for processing broken strips. However, it is difficult to clamp the strip during use, and there is a risk of breaking the strip during the clamping process. Therefore, a reversible cold rolling mill thin-gauge strip breaking processing tool is needed that can solve the technical problem of clamping the strip while ensuring that the strip is not easily broken. Utility Model Content
[0004] The present application aims to at least to some extent solve the technical problem that the clamp is not easy to clamp the ultra-thin strip and the ultra-thin strip is broken when the strip is broken. To this end, the present application provides a reversible cold rolling mill thin-gauge strip breaking processing tool.

[0006] Through the above structure, the first rod is hingedly connected to the second rod, and the two ends form a lever with the hinge point as the fulcrum, so that the broken strip can be clamped to facilitate re-winding. An arc-shaped bite portion is set between the clamping end and the hinge point, so as to reserve sufficient biting space for the broken strip, so that the clamping end can have sufficient fitting area, making the clamping more secure. During the clamping process, the unclamped part is the gravity falling part, and the arc-shaped bite portion can reduce the ratio of the unclamped part, thereby avoiding the phenomenon that the clamped part and the unclamped part are broken due to excessive gravity generated by the unclamped part. By setting the clamping end in parallel in the clamping state, it can be ensured that the strip at the clamping end can have a larger fitting surface, avoiding the strip breakage caused by excessive local pressure during the clamping process.

The canine-tooth-shaped protrusions on the first rod and the canine-tooth-shaped protrusions on the second rod are staggered. Through the mutual engagement of the canine-tooth-shaped protrusions, the friction force can be increased to prevent the strip from slipping from the clamping end.
[0010] In some embodiments, the horizontal length of the bite portion is about 12 cm, and the horizontal length of the bite portion can be between 10 cm and 15 cm. The specific length can be adjusted by the staff according to the width of the steel strip.
[0011] In some embodiments, the length of the handle end is about 1.5m. By extending the length of the handle end, the broken strip processing operator can have a certain safety distance from the strip and equipment, which is usually set to 1.5m. The implementer can increase or decrease the setting according to the effective safety distance between the operator and the strip.
[0012] In some embodiments, the clamping end, the engaging portion and the handle end are integrally formed, thereby ensuring the strength of the tool.
[0013] In some embodiments, the handle end is a structural member made of high-strength material, thereby ensuring the strength of the handle and preventing the handle from being bent and damaged, thereby causing.
[0014] In some embodiments, the handle end is a hollow structure to reduce weight and facilitate operation by staff.
[0015] In some embodiments, the handle end is provided with an anti-slip sleeve, which can increase the friction between the staff and the handle end, thereby making it more convenient to use.

[0027] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0028] See also Figure 1 , the embodiment of the present application provides a reversible cold rolling mill thin-gauge strip processing tool, the embodiment of the present application provides a reversible cold rolling mill thin-gauge strip processing tool comprising: a clamp-shaped body formed by a first rod 1 and a second rod 2 hingedly connected in the middle, the strip can be clamped by the clamp-shaped body, the clamp-shaped body has a clamping end 3 and a handle end 4 at both ends of the hinge point, the clamping end 3 is used to clamp the strip, the clamping end 3 on the first rod 1 and the clamping end 3 on the second rod 2 form two chucks, by adjusting the spacing of the handle ends 4, the spacing of the clamping ends 3 is continuously reduced until it is consistent with the thickness of the strip, thereby completing the clamping, the handle end 4, the length of the handle end 4 is much larger than the length of the clamping end 3; the bite portion 5, the bite portion 5 is located between the clamping end 3 and the hinge point, the bite portion 5 is in the shape of an arc, and the first rod 1 and the second rod 2 are both provided with the bite portion 5; the clamping end 3, the first rod 1 and the second rod 2 are both provided with a clamping end 3, and the clamping ends 3 are parallel to each other in the clamping state, and the clamping state is when the spacing between the two clamping ends 3 is between 0.3mm and 0.5mm, and the spacing between the clamping ends 3 is related to the thickness of the strip steel, and is currently usually 0.5mm. At this time, the clamping end 3 is in the clamping state, and the designer can adjust it according to the thickness of the clamped ultra-thin strip steel, wherein being parallel to each other means being roughly parallel, and during the manufacturing or design process, the two clamping ends 3 are provided with a certain deflection angle in the clamping state, such as an angle within ten percent, which has no significant impact on the present application.
[0029] Through the above structure, the first rod 1 is hingedly connected to the second rod 2, and the two ends form a lever with the hinge point as the fulcrum, so that the broken strip can be clamped to facilitate re-winding. An arc-shaped bite portion 5 is set between the clamping end 3 and the hinge point, so as to reserve sufficient biting space for the broken strip, so that the clamping end 3 can have a sufficient fitting area, making the clamping more secure. During the clamping process, the unclamped part is the gravity falling part, and the arc-shaped bite portion 5 can reduce the ratio of the unclamped part, thereby avoiding the phenomenon that the clamped part and the unclamped part are broken due to excessive gravity generated by the unclamped part.

The canine-tooth-shaped protrusions 6 on the first rod 1 and the canine-tooth-shaped protrusions 6 on the second rod 2 are staggered. Through the mutual engagement of the canine-tooth-shaped protrusions 6, the friction force can be increased to prevent the strip from slipping from the clamping end 3.
[0033] In some embodiments, see Figure 1 The horizontal length of the bite portion 5 is about 12 cm, and the horizontal length of the bite portion 5 can be between 10 cm and 15 cm. The specific length can be adjusted by the staff according to the width of the strip.
