The utility model discloses an extrusion processing can process and sell up catching groove or dovetail.
Description
Technical field
The utility model relates to machining field, particularly relates to a kind of without sword squeezing knife tool.
Background technology
The T-shaped cutter of prior art is all the cutter of band cutting edge, and CNC adds can only be processed into straight-line groove man-hour.Along with the development of mobile phone technique, in high-end handsets, plate or bonnet mostly adopt metal, need post forming, and on middle plate or bonnet, process back-off groove or dovetail groove so that post forming with CNC, the T-shaped cutter of prior art cannot be accomplished.In view of this, then the utility model is proposed, to improve the shortcoming that can not process back-off groove or dovetail groove in prior art.
Utility model content
For above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of without sword squeezing knife tool, and this adopts extrusion process can process back-off groove or dovetail groove without sword squeezing knife tool.
In order to solve the problems of the technologies described above, the utility model provides a kind of without sword squeezing knife tool, it comprises shank section and is arranged at the press section of described shank section head, described press section is cylindric, the diameter of described press section is greater than the diameter of described shank section, and described press section is vertical with described shank section.
Further improvement of the utility model is, described press section side is provided with extruding chamfering.
Further improvement of the utility model is, described extruding chamfering is 30 to 60 degree.
Further improvement of the utility model is, described extruding chamfering is 30 degree.
Further improvement of the utility model is, described shank section and described press section are structure as a whole.
Further improvement of the utility model is, described shank section and described press section adopt welding manner to fix.
Further improvement of the utility model is, described shank section and described press section adopt removably to fix.
Further improvement of the utility model is, described press section adopts wolfram steel to make.
Further improvement of the utility model is, described press section ti coat on diamond.
Compared with prior art, shank section head of the present utility model is provided with press section, and described press section is cylindric, and the diameter of described press section is greater than the diameter of described shank section, and described press section is vertical with described shank section; Described press section side is provided with extruding chamfering.The utility model adopts extrusion process can process back-off groove or dovetail groove.
Accompanying drawing explanation
Fig. 1 is back-off groove in middle plate or bonnet or dovetail groove schematic diagram;
Fig. 2 is embodiment one structural representation of the present utility model;
Fig. 3 is embodiment two structural representation of the present utility model.
In figure, each component names is as follows:
1-shank section;

Detailed description of the invention
To illustrate below in conjunction with accompanying drawing and detailed description of the invention further illustrates the utility model.
Fig. 1 is back-off groove in middle plate or bonnet or dovetail groove schematic diagram, as shown in Figure 1.
Embodiment one:
As shown in Figure 2, a kind of without sword squeezing knife tool, it comprises shank section 1 and is arranged at the press section 2 of described shank section 1 head, and described press section 2 is cylindric, the diameter of described press section 2 is greater than the diameter of described shank section 1, and described press section 2 is vertical with described shank section 1.
Particularly, as shown in Figure 2, described shank section 1 adopts integrative-structure with described press section 2; Or described shank section 1 adopts welding manner to fix with described press section 2; Or described shank section 1 adopts removably to fix with described press section 2.Described press section 2 adopts wolfram steel to make, and in its outer surface titanizing.
Embodiment two:
As shown in Figure 3, a kind of without sword squeezing knife tool, it comprises shank section 1 and is arranged at the press section 2 of described shank section 1 head, and described press section 2 is cylindric, the diameter of described press section 2 is greater than the diameter of described shank section 1, and described press section 2 is vertical with described shank section 1.
Particularly, as shown in Figure 3, described press section 2 side is provided with extruding chamfering 21.Described extruding chamfering 21 is 30 to 60 degree, is preferably 30 degree.Described shank section 1 adopts integrative-structure with described press section 2; Or described shank section 1 adopts welding manner to fix with described press section 2; Or described shank section 1 adopts removably to fix with described press section 2.Described press section 2 adopts wolfram steel to make, and in its outer surface titanizing.
Along with the development of mobile phone technique, in high-end handsets, plate or bonnet mostly adopt metal, need post forming, process back-off groove or dovetail groove so that post forming with CNC on middle plate or bonnet.CNC is equipped with the T-shaped cutter of prior art and of the present utility model without sword squeezing knife tool simultaneously, first on middle plate or bonnet, processes straight-line groove with the T-shaped cutter of prior art, then squeeze out back-off groove or dovetail groove with of the present utility model without sword squeezing knife tool.
The utility model has the advantage of, shank section head of the present utility model is provided with press section, and described press section is cylindric, and the diameter of described press section is greater than the diameter of described shank section, and described press section is vertical with described shank section; Described press section side is provided with extruding chamfering.The utility model adopts extrusion process can process back-off groove or dovetail groove.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
