Abstract

The utility model discloses an electrothermal cutter. The utility model comprises cutter handle parts, wherein, the front ends of the cutter handle parts are provided with cuneate blade parts; the longitudinal centers of the cutter handle parts are provided with slots through which the cutter handle parts form current circuits. The utility model is characterized in that the bottom of each slot is provided with a hole which is communicated with the two sides of each slot; the periphery of each hole and the edges of the two sides of each cuneate blade part form two necks whose cross section area is smaller than the cross section area of each cutter handle part. Because the two sides of each blade part are provided with two necks whose cross section area is smaller than the cross section area of each cutter handle part, the resistance of the necks is larger than the resistance of each cutter handle part. The two separated cutter handle parts are communicated with current, when the current flows the necks whose cross section area is smaller than the cross section area of each cutter handle part, because the resistance of necks becomes large, the blade parts generate heat. The part temperature of the blade parts can reach a red heat state from an incandescence state. Because only the blade parts are heated, the utility model has the advantages of small electric energy consumption, short heating time, a large amount of electrical energy saving, and time saving.

Description

Electric cutter

Technical field

The utility model relates to cutting tool, is specifically related to a kind of electric cutter that is used for the braid Polymer Processing.

Background technology

In the prior art, when fabric that weaving machinery wove reaches specified quantity, as chemical fabric, the plastics thick film, artificial leather, fabrics such as woven cloth, need braid is cut off, cutter on the weaving machinery can also seal the cut-out mouth fusing of braid when the cutting woven article simultaneously, therefore, this cutter also need the energising heating in use, existing cutter are when heating, be that handle of a knife portion and blade part with cutter all heats, because the volume of handle of a knife portion and blade part is all bigger, need consume the fusion temperature that a large amount of electric energy just can reach fabric during heating, heat time heating time is long.

The utility model content

The purpose of this utility model is, a kind of electric cutter that overcomes above-mentioned defective in the prior art is provided, and the heat time heating time of this electric cutter is short, and power consumption is low.

The technical scheme that the utility model provides is as follows: construct a kind of electric cutter, comprise handle of a knife portion, the front end of handle of a knife portion is the wedge shape blade part, handle of a knife portion has longitudinally shank portion is divided into identical two-part groove, the bottom of described groove is the hole that and the two sides of described groove are passed through connection mutually, and the both sides of the edge of the periphery in hole and described wedge shape blade part constitute two cross-sectional areas less than the long-pending neck of described handle of a knife cross section.

In above-mentioned electric cutter, two outsides of described wedge shape blade part also symmetry have deep-slotted chip breaker, and two peripheral peripheries with the hole of deep-slotted chip breaker constitute two necks that cross-sectional area is littler.

The utlity model has following advantage: because there are two cross-sectional areas the blade part both sides less than the long-pending neck of handle of a knife cross section, the resistance of neck will be greater than the resistance of handle of a knife portion, after separated two handle of a knife portion turn-on current, electric current is at the cross-sectional area of flowing through during less than the long-pending neck of handle of a knife cross section, because it is big that the resistance of neck becomes, this section blade part can generate heat, the temperature of blade part can reach by red to incandescent state, because the part that is heated only occurs in blade part, the electric energy that is consumed is also little, heat time heating time is short, can save a large amount of electric energy and time.

Description of drawings

Fig. 1 is the vertical view of the utility model electric cutter embodiment one;

Fig. 2 is the vertical view of the utility model electric cutter embodiment two.

The specific embodiment

Embodiment one: with reference to Fig. 1, provide a kind of electric cutter, comprise handle of a knife portion, the front end of handle of a knife portion is a wedge shape blade part 3, and electric cutter adopts high rigidity, oxidation resistant alloy sheet to make.Have the groove 11 that shank portion is divided into identical two

parts

1,6 longitudinally in handle of a knife portion, make handle of a knife portion constitute a current loop, the bottom of groove 11 is holes 5 that and the two sides of groove 11 are passed through connection mutually, and the both sides of the edge of the periphery in hole 5 and wedge shape blade part constitute two cross-sectional areas less than the long-pending

neck

4,7 of handle of a knife cross section; Change the size in the aperture in hole 5, can change the size of neck area affects 4,7, in separated two handle of a

knife portions

1,6 turn-on current, electric current at the cross-sectional area of flowing through less than the long-pending neck of handle of a

knife cross section

4,7 o'clock, because it is big that the resistance of

neck

4,7 becomes, this section blade part can generate heat, and the temperature of blade part can reach by red to incandescent state, because the part that is heated only occurs in blade part, the electric energy that is consumed is little.

Embodiment two, with reference to Fig. 2, the electric cutter that the utility model provides can also further improve on the basis of embodiment one, can offer 8, two deep-slotted chip breakers of identical deep-slotted chip breaker, 8 peripheral peripheries in two outside symmetries of wedge shape blade part and can constitute two

necks

9,10 that cross-sectional area is littler with hole 5.This structure is more convenient for cutting different fabrics, heats faster.

With reference to Fig. 1, also be provided with the fixing hole 2 that is used to install in the separated handle of a knife of two of the above-mentioned electric cutter portion.The blade part structure of above-mentioned electric cutter can be made difform blade according to different split requirements.

Claims

1, electric cutter, comprise handle of a knife portion, the front end of handle of a knife portion is the wedge shape blade part, handle of a knife portion has longitudinally and makes handle of a knife portion constitute the groove of current loop, it is characterized in that, the bottom of described groove is the hole that and the two sides of described groove are passed through connection mutually, and the both sides of the edge of the periphery in hole and described wedge shape blade part constitute two cross-sectional areas less than the long-pending neck of described handle of a knife cross section.

According to the described electric cutter of claim 1, it is characterized in that 2, two outsides of described wedge shape blade part also symmetry have identical deep-slotted chip breaker, two peripheral peripheries with the hole of deep-slotted chip breaker constitute two necks that cross-sectional area is littler.

3, according to claim 1 or 2 described electric cutters, it is characterized in that, also be provided with fixing hole in the handle of a knife portion that described two separations have.
