[0004] In the production of workpieces, when the uncoiled strips are formed, the continuous strips need to be cut to a fixed length, so the quantitative shearing process and device for continuous strips are an important machine tool. In the existing quantitative shearing process and device for continuous strips, the shearing blades are moved up and down to perform shearing. Since the cutting points of the shearing blades are all fixed lines, the shearing is concentrated on the upper and lower cutting edges. , resulting in curling of the incision

Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0025] A process for quantitative shearing of continuous strips,
[0026] In the first embodiment of the present invention, when the moving speed of the continuous strip is 55m / min, the cutting edge angle of the shearing blade is 1.7°, and the two shearing blades are paired with each other at a shearing angle of 85°.
[0027] In this embodiment, one of the cutting blades is used to perform two pairs of cutting blades according to a cutting angle of 85°, that is, th...

Abstract
The invention discloses a quantitative shearing process method and device for a continuous belt material. The method comprises the following steps: when the motion speed of the continuous belt material is 55-60 m / min, the shearing edge angle of each shearing edge is 1.7-2.1 degrees, and the shearing operation is carried out by two shearing edges according to the shearing angle of 85-90 degrees. The device comprises a shearing seat (5) which is provided with an edge used for penetrating through a plate and is hinged to a machine tool frame, a shearing device which is arranged on the shearing seat (5) and can act on the plate in a timed manner, a drive device which is arranged on the machine tool frame and used for driving the shearing seat (5) to swing, and a switch device used for receiving a swing speed signal of the shearing seat (5) and controlling the time interval of action of the shearing device on the plate. The belt material is shorn during swinging of the shearing seat (5) in a continuous traveling process of the belt material, so that the shearing device has the moving speed corresponding to the continuous traveling speed of the belt material in a shearing process, the quality of a shear hole is improved, and turned edges are no longer generated.
Description
[0001] 1. Technical field [0002] The invention relates to a quantitative shearing process method and device, in particular to a quantitative shearing process method and device for continuous strips. [0003] 2. Background technology [0004] In the production of workpieces, when the uncoiled strips are formed, the continuous strips need to be cut to a fixed length, so the quantitative shearing process and device for continuous strips are an important machine tool. In the existing quantitative shearing process and device for continuous strips, the shearing blades are moved up and down to perform shearing. Since the cutting points of the shearing blades are all fixed lines, the shearing is concentrated on the upper and lower cutting edges. , resulting in curling of the incision. [0005] 3. Contents of the invention [0006] In order to overcome the above-mentioned technical disadvantages, the object of the present invention is to provide a quantitative shearing process and d...
