Abstract
The utility model relates to an arc surface bending tool which comprises an arc surface roller and a cutter handle. The arc surface bending tool is characterized in that the arc surface roller is arranged on the lower portion of the cutter handle, and the arc surface roller is directly connected to the cutter handle in a sleeved mode. The arc surface roller is in interference fit with the cutter handle, and an inner hole of the arc surface roller and the lower end of the cutter handle are rectangular. In practical use, a proper arc surface roller is selected according to the arc surface radian needing processing, and the arc surface roller is directly connected to the cutter handle in the sleeved mode. Only the arc surface roller needs to be replaced when the arc surface radian needs to be changed. The arc surface bending tool is simple in structure and convenient to use.
Description
Technical field
The utility model relates to the production and processing field of tool, specifically a kind of cambered surface bending tool.
Background technology
Punching press refers to that depended on pressure machine and mould apply external force to sheet material, band, tubing and section bar etc., makes it to produce plastic deformation or separation, thereby obtains the forming and machining method of the workpiece (stamping parts) of required form and size.Punching press and forging belong to plastic working (or claiming pressure processing) together, are collectively referred to as forging and stamping.The blank of punching press is mainly hot rolling and cold rolling steel plate and steel band.In global steel, have 60～70%, sheet material, wherein finished product is made in the punching press of most of process.The vehicle body of automobile, chassis, fuel tank, radiator fin, the drum of boiler, the housing of container, the iron core silicon-steel sheet of motor, electrical equipment etc. is all punch process.In the products such as instrument and meter, household electrical appliance, bicycle, office machinery, household utensil, a large amount of stamping parts are also arranged.Stamping parts is compared with foundry goods, forging, has thin, even, light, strong characteristics.Punching press can be made additive method and is difficult to the workpiece with reinforcement, rib, fluctuating or flange of manufacturing, to improve its rigidity.Owing to adopting precision die, workpiece accuracy can reach micron order, and repeatable accuracy is high, specification is consistent, and nest, boss etc. can punching press portal.Cold-stamped part is generally no longer through machining, or only needs a small amount of machining.Heat-punch member precision and surface state be lower than cold-stamped part, but still be better than foundry goods, forging, and the machining amount is few.
Punching press cutter head shape matching commonly used is single, for the processing work that needs on a small quantity the cambered surface bending, is generally by the customization cutter head, for different cambered surfaces, often needs different cutter heads.Lack at present a kind of simple in structure, convenient and practical, and the cambered surface bending tool that can replace.
Summary of the invention
The utility model, for above technical problem, provides a kind of simple in structure, convenient and practical, and the cambered surface bending tool that can replace.
The utility model is achieved through the following technical solutions.
A kind of cambered surface bending tool, comprise cambered surface roller, handle of a knife, it is characterized in that the cambered surface roller is arranged on the handle of a knife bottom, and the cambered surface roller directly is socketed on handle of a knife, and cambered surface roller and handle of a knife adopt interference fit.Cambered surface roller endoporus and handle of a knife lower end are rectangle.
In actual the use, the cambered surface radian of processing, select suitable cambered surface roller as required, and the cambered surface roller shell is connected on handle of a knife and gets final product.When needs change the cambered surface radian, only the cambered surface roller need to be replaced and got final product.
The utility model is simple in structure, easy to use.
The accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model cross-sectional view, wherein:
1-cambered surface roller, the 2-handle of a knife.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of cambered surface bending tool, comprise cambered surface roller 1, handle of a knife 2, it is characterized in that cambered surface roller 1 is arranged on handle of a knife 2 bottoms, and cambered surface roller 1 directly is socketed on handle of a knife 2, and cambered surface roller 1 adopts interference fit with handle of a knife 2.Cambered surface roller 1 endoporus and handle of a knife 2 lower ends are rectangle.
In actual the use, the cambered surface radian of processing, select suitable cambered surface roller 1 as required, and cambered surface roller 1 is socketed on handle of a knife 2 and gets final product.When needs change the cambered surface radian, only cambered surface roller 1 need to be replaced and got final product.
The utility model is simple in structure, easy to use.
