Problems solved by technology
This means that when the mold is working, all cutting edges participate in the cutting almost at the same time. In addition, the width of the cavity is very narrow, and the wire cannot be threaded during wire cutting. Cutting with 0° rake angle, so the cutting force is very large

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings. The protection scope of the present invention is not limited to the following:
[0017] Such as figure 1 with figure 2 As shown, a large rake angle staggered shearing mold includes a base 1, a static mold 2 and a movable mold 3. The static mold 2 is installed in the base 1, and a guide rail 8 is installed on the outer surface of the base 1. , The movable mold 3 is installed in the guide rail 8, the upper end of the movable mold 3 is connected with an oil cylinder, and the movable mold 3 moves horizontally along the guide rail 8 under the push of the oil cylinder, and the movable mold 3 and the static mold 2 both have a cavity 5. The workpiece 4 passes through the cavity 5 of the movable mold 3 and the static mold 2 at the same time. When the movable mold 3 is misaligned with the static mold, the workpiece 4 is cut. The upper surface of the cavity 5 of the movable mold 3 is ...

The invention discloses a large rake angle staggering shearing die. The large rake angle staggering shearing die comprises a base (1), a static die (2) and a moving die (3), wherein the static die (2) is installed in the substrate (1), a guide rail (8) is installed on the outer side face of the base (1), the moving die (3) is installed in the guide rail (8), the upper end of the moving die (3) is connected with an oil cylinder, the moving die (3) horizontally moves along the guide rail (8) under the pushing of the oil cylinder, the moving die (3) and the static die (2) are each provided with a cavity (5), a workpiece (4) penetrates through the cavities (5) of the moving die (3) and the static die (2), an inclined moving die front cutter face (7) is formed in the upper surface of the cavity (5) of the moving die (3), and the moving die (3) is provided with a large rake angle. The large rake angle staggering shearing die has the advantages of cutting the workpiece lightly, reducing cutting force, workpiece deformation and die vibration and deformation, and prolonging the service life of the die.
Description
Technical field [0001] The invention is a staggered shearing die used in a cold-formed forming production line, belonging to the technical field of moulds used for a cold-formed forming rolling mill, in particular a staggered shearing die with a large rake angle. Background technique [0002] The strip profile rolled by a cold-formed rolling mill must be cut according to different lengths during production according to the requirements of use. The cutting method can basically be divided into two types, namely cutting with waste and cutting without waste. The non-scrap cutting method adopts the dislocation phase shear, that is, the cavities of the movable mold and the static mold are processed into a pattern consistent with the cross section of the workpiece by the method of wire cutting, and the workpiece passes through the cavity and the movable mold is in the cylinder. Drive down translation, dislocation of the cavity of the movable mold and the cavity of the static mold, ther...
