Problems solved by technology
The cutting operation of the steel strip is completed by the steel strip cutting device, but the performance of the previous steel strip cutting device is not good, and the operation is inconvenient. It needs to be cut many times to barely achieve the effect of the cutting surface. Occasionally, the rolling mill will be broken during the process. When this happens, it must be stopped to deal with it, and the raw materials more than ten meters before and after the fracture will be scrapped, which will seriously affect the production efficiency, waste raw materials and increase production costs.

Embodiment Construction
[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] Such as Figure 1~6 As shown, a steel strip cutting device includes a handle 1, a main body bracket 2, a camshaft 3, a moving tool 4, a fixed tool 5, a tool fixing bolt 6, an integral fixing bolt 7, a second spring washer 8, and a handle fixing bolt 9 , lock nut 11, disc-shaped shrapnel 12, first spring washer 13, cam 14, baffle plate 15 and pressure plate 16, one side of the main body bracket 2 is provided with a steel strip inlet groove 10, the width of the steel strip inlet groove 10 Slightly greater than the steel strip thickness, its length is slightly less than the length of the movable cutter 4 or the fixed cutter 5. The fixed cutter 5 is arranged on the top of the steel strip inlet groove 10, and the movable cutter 4 is arranged on the bottom of the steel strip inlet groove 10, and is positioned at the same side of the main bod...

The invention discloses a novel steel strip cutting device. The novel steel strip cutting device comprises a handle, a body support, a cam shaft, a movable cutter, a fixed cutter and a cam. A steel strip inlet groove is formed in the body support. The fixed cutter and the movable cutter are arranged on the upper side and the lower side of the steel strip inlet groove respectively. The movable cutter is installed on the body support. The cam is located in an eccentric hole. The handle is arranged at one end of the cam shaft and rotated to drive the cam shaft to rotate. Baffles are arranged on the left side and the right side of the movable cutter respectively. The cam shaft rotates to drive the movable cutter to reciprocate in the vertical direction. Shearing force is formed by relative movement between the movable cutter and the fixed cutter. By means of the novel steel strip cutting device, the steel strip shearing effect can be improved, a steel belt can be even, straight and free of bending and warping, the steel strip connecting effect is effectively improved, steel strip disconnecting is avoided, the production efficiency in a production site is improved, and the safety coefficient in the production site is increased; meanwhile, each cutter can be repeatedly used for four periods, and the service life of the novel steel strip cutting device is effectively prolonged.
Description
technical field [0001] The invention belongs to the field of flux cored wire production, in particular to a steel strip cutting device. Background technique [0002] In the current production of flux-cored welding wire, raw material steel strips are rolled and wide-shaped when they enter the workshop. This wide-shaped coiled steel strip is cut into multiple narrow steel strips through the strip cutting process, and then A plurality of narrow steel strips are connected end to end to form one and then sent to the next process for use. The end-to-end connection of narrow steel strips is done by the steel strip butt welding machine, but before using the steel strip butt welding machine, it must be ensured that the end faces of the two steel strips to be butted are a straight line, flat, straight, not bent and not Otherwise, the steel strips connected together will be broken during use, which not only affects the production progress, but also poses a major safety hazard. [000...
