Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled steel strips, in particular to a cold-rolled steel strip stripping mechanism. Background Art

[0002] Cold-rolled steel strip is made of hot-rolled coil and is rolled at room temperature below the recrystallization temperature. It includes plates and coils. Many domestic steel mills such as Baosteel, Wuhan Iron and Steel, Anshan Iron and Steel, etc. can produce it. Among them, the ones delivered in sheets are called steel plates, also called box plates or flat plates; the ones delivered in long lengths in coils are called steel strips, also called coils. The mother coils in the production of cold-rolled steel strips are generally relatively wide. In order to facilitate subsequent cutting, processing and use, the mother coils can be divided into several narrower strips by stripping. These strips can be cut and processed in a targeted manner, which can greatly improve production efficiency and product quality. Stripping can also reduce waste generation and improve resource utilization.

[0003] When cold-rolled steel strips are slit, a slitting machine is required. The existing slitting machine has a slow cutting efficiency. When the machine operates continuously, it is in constant contact and friction with the steel strip, which will increase the temperature and cause residual stress in the steel sheet after cutting. The residual stress will cause the cut edge to warp or twist, deform, or even crack, affecting the quality of the steel strip. Utility Model Content

[0004] The main purpose of the utility model is to provide a cold-rolled steel strip slitting mechanism which can quickly slit the steel strip by setting a cutter head; to avoid the steel strip from warping and curling after cutting by setting a first clamping rod and a second clamping rod; and to greatly reduce the temperature of the steel strip after slitting by setting a metal cooling layer to avoid affecting the performance of the steel strip.

[0005] In order to solve the above technical problems, the utility model discloses a cold-rolled steel strip slitting mechanism, comprising: a frame, a mounting platform is provided in the middle of the frame, mounting panels are provided on both sides of the top of the frame, and a driving motor is provided on the mounting platform; a first working roller is arranged on the mounting panels on both sides, a corresponding second working roller is arranged on the lower side of the first working roller, and knife heads with uniform intervals are arranged on the first working roller and the second working roller, a collecting rod is provided on the front side of the first working roller, a fixing rod is provided on the rear side of the first working roller, a first clamping rod is provided on the rear side of the fixing rod, a second clamping rod is provided at the bottom of the first clamping rod, and anti-slip wear patterns are provided on the outer side of the second clamping rod; a cross bar is arranged on the front side of the mounting panel, and two groups of cross bars are provided with sliding rods with uniform intervals; a metal cooling layer is provided on the outer sides of the first clamping rod, the second clamping rod and the sliding rod.

[0006] According to one embodiment of the utility model, the driving motor drives the second working roller to rotate.

[0007] According to one embodiment of the utility model, the number of the above-mentioned cutter heads is 4 groups.

[0008] According to an embodiment of the utility model, a fixed anti-slip platform is provided at the bottom of the frame.
