Abstract
A twin-peak-blade cutter for a rolling line is composed of a cutter (1), a rolling part (2), a discharge plate (3) and a concave die (4). The rolling part (2) passes the discharge plate (3) and the concave die (4). The twin-peak-blade cutter is characterized in that the cutter (1) is W-shaped, and two points of two cutter peaks contact the rolling part (2) at the same time. The twin-peak-blade cutter for the rolling line is simple in structure, service life is prolonged, the cut section of the rolling part has no burrs and unevenness, blades of the cutter are simple in shape and convenient to sharpen, and sharpness of the blades is guaranteed.
Description
Technical field
The utility model relates to vehicle bumper beam manufacture field, particularly relates to a kind of for the bimodal sword cutting knife on rolling-line.
Background technology
The pilot beam that vehicle uses, material is B5L00A, and expecting thick is 1.6mm, and it is one and passes through rolling formation, and the roll-in workpiece completing by preseting length cut-out.As shown in Figure 1, when rolling production line start is produced, machine for rolling parts 2 passes through on stripper 3 and die 4 in cutting knife design on conventional roll line ball, and when machine for rolling parts reaches preseting length by length, rolling-line is shut down, and cutting knife 1 moves downwards, cuts off machine for rolling parts 2.Due to traditional cutting knife shape, stressed more complicated, cutting edge wearing and tearing during cut-out, fracture the sound of sth. throbbing or bursting lip reflex happen occasionally, and the workpiece section convex-concave cutting out is more serious, and burr is also larger.
Summary of the invention
For above-mentioned defect, it is a kind of for the bimodal sword cutting knife on rolling-line that the purpose of this utility model is to provide, and uses Cr12MoV material to make, and cutoff edge becomes W shape, and through Quenching Treatment, by two, cutter peak point touch roll casting die.
The technical solution of the utility model is achieved in the following ways: a kind of for the bimodal sword cutting knife on rolling-line, by cutting knife, machine for rolling parts, stripper, die, formed, machine for rolling parts passes through on stripper and die, it is characterized in that: described cutting knife becomes W shape, by two, cutter peak point while touch roll casting die.
Described bimodal sword cutting knife material is Cr12MoV, and hardness is HRC58-62.
The utility model, simple in structure, cutting blade abrasion vibration is little, while just contacting with machine for rolling parts, cutting knife section is 2 contacts, the oblique sword principle of similar scissors when separated, progressively separated, cutting blade abrasion is also little like this, vibration has also alleviated, and has reduced the vibration of other related components on rolling-line and impact; Machine for rolling parts section is without burr and rough and uneven in surface situation; Owing to being two some contacts, impulsive force is disperseed in addition, reduced subsiding of cutting plane.Cutoff edge mouth-shaped is simple, reconditioning convenient, has guaranteed the sharpness of cutting edge, and the workpiece burr cutting out is little, has cut follow-up polishing operation, improves service life.
Accompanying drawing explanation
Fig. 1 is existing rolling-line upper cutter work cut-away illustration.
Fig. 2 is the utility model schematic diagram.
Fig. 3 is the utility model cut-away illustration of working on rolling-line.
In figure: 1 cutting knife, 2 machine for rolling parts, 3 strippers, 4 dies.
the specific embodiment
By Fig. 2,3, known, a kind ofly for the bimodal sword cutting knife on rolling-line, cutting knife 1, machine for rolling parts 2, stripper 3, die 4, consist of, cutting knife 1 is made by Cr12MoV material, and the bimodal sword of 1 one-tenth W shape of cutting knife is HRC58-62 through Quenching Treatment hardness; When rolling production line start is produced, machine for rolling parts 2 passes through on stripper 3 and die 4, and when machine for rolling parts 2 reaches preseting length by length, rolling-line is shut down, and cutting knife 1 moves downwards, cuts off machine for rolling parts 2.Cutting knife 1 passes through two, cutter peak point touch roll casting die when work, and the oblique sword principle of similar scissors when separated is progressively separated, and cutting knife 1 wearing and tearing are also little like this, and vibration has also alleviated, and has reduced the vibration of other related components on rolling-line and impact; Machine for rolling parts section is without burr and rough and uneven in surface situation, and cutoff edge mouth-shaped is simple, reconditioning convenient, has guaranteed the sharpness of cutting edge.
Claims (2)
1. one kind for the bimodal sword cutting knife on rolling-line, by cutting knife (1), machine for rolling parts (2), stripper (3), die (4), formed, machine for rolling parts (2) passes through on stripper (3) and die (4), it is characterized in that: described cutting knife (1) becomes W shape, by two, cutter peak point while touch roll casting die (2).
2. according to claim 1 a kind of for the bimodal sword cutting knife on rolling-line, it is characterized in that: described cutting knife (1) material is Cr12MoV, and hardness is HRC58-62.
