The traditional process arrangement of the shearing line of the thick plate production line always adopts the steps of head and tail shearing, bilateral shearing of a steel plate and bilateral shearing of the length of the steel plate to be fixed-length shearing, and the thick plate product is sheared into a finished steel plate meeting the size required by a customer in the mode. The deckle edge product need not cut the both sides, often can cut the production at the scale and cut the bottleneck in the shear line shearing process, and the crop is cut the head and is cut the appearance and can be emptied the phenomenon, and concrete shearing method is as follows:
the deckle edge steel sheet leans on the limit in inspection rack export, guarantees steel sheet limit portion location. And after positioning, the steel plate enters a head-cutting shear area, stops at the induction grating of the head-cutting shear, and waits for a shear model to issue a head-tail shearing and segmented shearing plan of the steel plate. And after the shearing plan is generated, the steel plate enters a shearing head shearing body area, and head and tail fillet shearing, head and tail shearing and segmentation are carried out according to the shearing plan. And (4) finishing the segmented steel plate, wherein the steel plate is directly sheared to the fixed-length shearing area through the two sides, and the fixed-length shearing of the front steel plate is finished before waiting on the inlet roller way. And after the front steel plate is sized, stopping at the position of the sizing shear induction grating, and waiting for a sample shearing plan and a sizing plan of the lower steel plate under the shearing model. And after receiving the sample shearing plan and the fixed-length plan, the steel plate enters the position of the edge-approaching device to carry out fixed-length edge-approaching shearing. After the side approach is completed, the steel plate enters the fixed-length shear to perform head rectangular cutting so as to ensure the right angle of the head of the steel plate, and then the test sample shear and the fixed-length shear are performed so as to complete the shear of the fixed-length contract. And conveying the sized steel plate to a spray printing machine for spraying and engraving a finished product. The specific material flow and process arrangement is as follows:
the prior art has the following problems:
this kind of mode of shearing efficiency is comparatively low, and when the scale was cut in the preceding piece steel sheet and was carried out the scale, back piece segmentation steel sheet can only wait for at the scale entry roll table of cutting, and the process synchronism is not enough. Especially when many times chi is cuted and deckle edge steel sheet is cuted, the segmentation ability that the crop was cut is greater than the scale ability that the scale was cut far away, often because the scale speed is not enough for the scale, causes the crop to cut the jam, and the line productivity is extravagant.
