[0002] The uncoiling, blanking and shearing of steel coils in the automotive industry usually uses blanking dies for blanking production to obtain arc-shaped sheets. However, this blanking operation method not only has high mold costs, but also has a relatively low utilization rate of steel. Low, which brings a lot of waste to production

Embodiment Construction
[0025] The shearing mechanism also includes a manual tool gap adjustment device 8 adapted to shearing of sheets of different thicknesses, so as to adapt to the shearing of sheets of different thicknesses, which improves the versatility of the modification device. The shearing mechanism also includes a pressing device 15, the pressing device 15 includes a pressing plate 23, a spring 22 and a bolt 21, the lower end of the bolt 21 is welded to the pressing plate 23, the spring 22 is sleeved on the bolt 21, and is installed with the upper tool After the support 6 produced the pre-tightening force, the upper end was fixed with a nut, and the position of the clamping plate 23 and the pre-tightening force of the spring 22 could be adjusted by the nut on the upper end of the bolt 21. When the upper arc cutter 14 went down, the clamping plate 23 preceded the The upper arc cutter 14 contacts the sheet material, and presses the sheet material and the plane 7 at the lower tool support plac...

The invention discloses an arc-shaped cutter shearing machine which comprises an entry-side transmission mechanism, a shearing mechanism and an exit-side transmission mechanism, wherein the three mechanisms are sequentially arranged and installed on an installation soleplate, i.e. the shearing mechanism is positioned at the middle position of the entry-side transmission mechanism and the exit-side transmission mechanism; the entry-side transmission mechanism comprises a belt transmission mechanism and a roller device, wherein the belt transmission mechanism and the roller device are positioned on the installation soleplate; the exit-side transmission mechanism comprises a belt transmission mechanism and a roller device; and the shearing mechanism comprises an upper circular-arc cutter anda lower circular-arc cutter, wherein the upper circular-arc cutter is installed on an upper cutter installation bracket, the lower circular-arc cutter is installed on a lower cutter installation bracket, and the upper circular-arc cutter and the lower circular-arc cutter are formed into a whole through dampers arranged at both ends of the upper cutter installation bracket and the lower cutter installation bracket. Through the arc-shaped cutter shearing machine with the special structure, the mould cost is lowered, and meanwhile, the utilization ratio of materials is improved.
Description
technical field [0001] The invention relates to an arc-shaped knife-shearing machine, in particular to an arc-shaped knife-shearing machine for automobile steel plates or metal strips. Background technique [0002] The uncoiling, blanking and shearing of steel coils in the automotive industry usually uses blanking dies for blanking production to obtain arc-shaped sheets. However, this blanking operation method not only has high mold costs, but also has a relatively low utilization rate of steel. Low, to bring a lot of waste to production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an arc-shaped knife and scissors machine aiming at the problems existing in the prior art, the purpose of which is to increase the utilization rate of materials while reducing the mold cost. [0004] The technical solution of the present invention is that this arc-shaped knife-scissor includes three mechanisms: an entry-side trans...
