CN203380421U - Cutter for cutting curve sheet - Google Patents

Abstract

The utility model discloses a cutter for cutting a curve sheet. The cutter comprises an upper cutter piece and a lower cutter piece. Blades of the two cutter pieces are arranged oppositely, the edges of the blades of the two cutter pieces are mutually meshed to cut a sheet workpiece into the curve of the curve sheet. The cutter has the advantage that a product with a required shape is obtained by conducting cutting through the cutter to form the curve sheet and conducting further cutting on the curve sheet. The utilization rate of the curve sheet is improved by about 10% compared with that of the existing linear sheet.

Description

A kind of cutter for the shearing curve thin plate

Technical field

The utility model relates to a kind of cutter, relates in particular to a kind of cutter for the shearing curve thin plate.

Background technology

The edge of a knife of shearing at present the thin plate cutter is shaped as linear pattern, and sheet material is cut into to straight plate on request, for example shears the motor stator period of the day from 11 p.m. to 1 a.m, need on straight steel plate, according to stator profile, further cut out (referring to Fig. 1), but this method is not high to the utilization rate of sheet material.

The utility model content

The utility model purpose: the purpose of this utility model is to provide a kind of cutter for the shearing curve thin plate, and it is higher that it shears the curve thin plate utilization rate formed.

Technical scheme: a kind of cutter for the shearing curve thin plate described in the utility model, comprise upper slitter part and lower cutter part, in opposite directions, and the knife edge of two cutter parts is for mutually coincideing, sheet workpiece can being cut into to the curve of curve thin plate for two cutter part blades.

Wherein, the radius of curvature of described cutter part knife edge curve is identical with the motor stator radius.The material of described cutter is chromium 12.

The course of work: sheet material is placed between upper and lower cutter part, and the cutter part motion down of upper slitter part, be cut into two blocks of sheet materials that curve shape is identical by a sheet material.

Beneficial effect: compared with prior art, its advantage is for by this cutter, shearing the forming curves thin plate for the utility model, and on the curve thin plate, further cutting obtains the product of required form, and this curve thin plate improves 10% left and right than the utilization rate of existing linear pattern thin plate.

The accompanying drawing explanation

Fig. 1 is the schematic diagram at linear pattern thin plate cutting motor stator;

Fig. 2 is structural representation of the present utility model;

Fig. 3 utilizes the utility model cutter to shear the curve thin plate schematic diagram obtained;

The schematic diagram of Fig. 4 and Fig. 5 cutting motor stator on the curve thin plate.

The specific embodiment:

As shown in Figure 2-5, cutter of the present utility model comprises upper and lower two cutter parts, wherein upper slitter part 1 is placed in lower cutter part 2 edge one sides, two cutter part blades in opposite directions and knife edge be recessed bent curve-like, upper and lower cutter part blade can coincide mutually, cutter part concave surface under the convex surface correspondence of upper slitter part, cutter part convex surface under upper slitter part concave surface correspondence, the radius of curvature of knife edge curve is identical with the motor stator radius, and this cutter adopts chromium 12 to make simultaneously.During use, sheet material is placed between upper and lower cutter part, upper slitter part 1 cutter part 2 motions down, be cut into two blocks of sheet materials that curve shape is identical by a sheet material.Relatively drawn by Fig. 1 and Fig. 5, utilize curve sheet cutting stator, the gap between adjacent stators is less than the gap utilized between linear pattern thin plate cutting stator.

Claims (3)

1. the cutter for the shearing curve thin plate is characterized in that: comprise upper slitter part (1) and lower cutter part (2), in opposite directions, and the knife edge of two cutter parts is for mutually coincideing, sheet workpiece can being cut into to the curve of curve thin plate for two cutter part blades.

2. a kind of cutter for the shearing curve thin plate according to claim 1, it is characterized in that: the radius of curvature of described cutter part knife edge curve is identical with the motor stator radius.

3. a kind of cutter for the shearing curve thin plate according to claim 1, it is characterized in that: the material of described cutter is chromium 12.
