Abstract

The utility model discloses a molding cutter which comprises a body, wherein the lower half portion of the body horizontally extends leftwards to form a lower convex column, the upper half portion of the body horizontally extends leftwards to form an upper convex column, a curved surface is arranged between the upper convex column and the lower convex column, and a groove is formed between the curved surface and the upper surface of the lower convex column. The molding cutter is characterized in that the end face of the lower convex column extends leftwards to form a third convex column. Due to the third convex column, a groove can be produced on the lower end face of a door frame body, and therefore by means of a T-shaped strip with a T-shaped cross section, a door frame decorative plate is fixed in the groove of the door frame body. Ropes and nails are not necessary, attractiveness is achieved, and operation is convenient. In addition, due to the fact that an included angle between the groove of the molding cutter and the upper surface of the lower convex column is circular arc transition, correspondingly generated edges of the door frame are circular arc transition, wherein the edges are positioned between front ends and the lower surfaces of the convex columns, and the phenomena of contraction and concentration of nearby paint cannot occur.

Description

A kind of forming cutter

Technical field

The utility model relates to a kind of forming cutter, relates to particularly a carpenter and uses forming cutter, uses forming cutter in particular for the door-plate frame with a carpenter of core integrated structure.

Background technology

Wooden gate often adopts the mode of the door core decorative panel combination of peripheral doorframe and centre to make up for attractive in appearance.Referring to Fig. 3, the structure of existing forming cutter 5 ' comprises a body 50, and the Lower Half of this body 50 is horizontal-extending projection 51 once left, and the end face 511 of this time projection 51 is flat; The first half of this body 50 is projection 52 on the horizontal-extending one left, and front end 521 of projection 52 extends longer distance than the front end 511 of lower projection 51 left with respect to body 50 on this.Be provided with a curvilinear plane 53 between upper projection 52 and the lower projection 51, form a groove 54 between the upper surface of this curvilinear plane 53 and lower projection 51.Referring to Fig. 1 and Fig. 2, the doorframe structure 1 ' that this forming cutter 5 ' processes is as follows: it comprises a body 10, and the middle part of this body 10 is extended to the right and established a projection 11, and the front end face 111 of this projection 11 is a plane, upper surface is a curvilinear plane 112, and lower surface also is a plane.The top body of this projection 11 has a upper surface 12, and there is a lower surface 13 below.During use, one end of door core decorative panel 3 is resisted against position between projection 11 lower surfaces and the lower surface 13, and then be posted by between a lower surface of core decorative panel 3 and the lower surface 13 with a soft rope 2, with nail 4 rope is fixed between the lower surface 13 afterwards, then the end of this core decorative panel 3 is fixed between projection 11 and the rope 4, finishes assembling.

There is following shortcoming in this kind assembling mode: because need to be by the fixing rope of nail, the end of nail is exposed, and is not attractive in appearance, and lower surface 13 is little with the space between the door core decorative panel 3, fixedly nail inconvenience on operating.

The utility model content

The purpose of this utility model is to provide a kind of forming cutter, to solve the above-mentioned problems in the prior art.

The technical scheme that the utility model provides is as follows:

A kind of forming cutter, comprise a body, the Lower Half of this body is horizontal-extending projection once left, the first half of this body is projection on the horizontal-extending one left, upward be provided with a curvilinear plane between projection and the lower projection, form a groove between the upper surface of this curvilinear plane and lower projection, it is characterized in that: the end face of described lower projection extends left establishes one the 3rd projection.

In preferred embodiment of the present utility model, the end face of this time projection is flat.

In preferred embodiment of the present utility model, the front end of upper projection extends longer distance than the front end of lower projection left with respect to body.

In preferred embodiment of the present utility model, the front end of the front end of upper projection and the 3rd projection is concordant on the same vertical curve or not on same vertical curve.

In preferred embodiment of the present utility model, the angle between groove and the lower projection upper surface is smooth transition.

In preferred embodiment of the present utility model, described smooth transition is arc transition.In the prior art, because front end face 111 and the edge between the lower surface 113 of projection 11 are the right angle, near paint can produce contraction, is bonded at herein, affects outward appearance.And the applicant is made as after the arc transition herein, finds that the paint shrinkage phenomenon disappears.

In preferred embodiment of the present utility model, the radius of circular arc is 0.5-3mm.

Seen from the above description, the utility model provides a kind of forming cutter, it comprises a body, the Lower Half of this body is horizontal-extending projection once left, the first half of this body is projection on the horizontal-extending one left, is provided with a curvilinear plane between projection and the lower projection on this, forms a groove between the upper surface of this curvilinear plane and lower projection, wherein, the end face of described lower projection extends left and establishes one the 3rd projection.Because the 3rd projection, its lower surface at the doorframe body can produce a groove, by this, can be T-shaped of T shape by a cross section, doorframe trim is fixed in the groove of this doorframe body.Need not rope and nail, attractive in appearance, and easy to operate.In addition, because the groove of forming cutter and the angle between the lower projection upper surface are arc transition, this is so that front end face and the edge between the lower surface of the projection of the corresponding doorframe that produces are arc transition, and near paint can not produce the phenomenon of shrinking and concentrating in together.
