Technical Field
The utility model relates to a blade of processing stainless steel, more specifically says that it relates to an indexable profile blade of processing stainless steel.
Background
In the prior art, the cutter for machining the profile of the stainless steel shell of the mobile phone is a whole hard alloy cutter in the traditional machining process. Due to the outer diameter of the profile between 15 and 35mm, the monolithic cemented carbide has several disadvantages: 1. one edge is broken, so that the machined part has line marks, and the whole cutter is scrapped; 2. only the blade part participates in cutting, the handle part only plays a supporting role, and the cost is wasted due to the integral use of hard alloy. Therefore, there is a problem that the overall life of the tool is short.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art existence, the utility model aims to provide an indexable profile blade of processing stainless steel has extension cutter life's effect.
In order to achieve the technical purpose, the utility model provides a following technical scheme: the indexable contour insert for machining stainless steel comprises a square cutter body, wherein cutting edges are arranged on four sides of the cutter body respectively and are in a concave shape, each cutting edge comprises two first cutting lines with the length of 3.25mm, a second cutting line with the length of 7.5mm is arranged between the two first cutting lines, the edge of each first cutting line is chamfered, and a center hole matched with a cutter bar is arranged in the middle of the cutter body in a penetrating mode along the thickness direction.
Through adopting above-mentioned technical scheme, pass through the centre bore with the blade and fix on the cutter arbor, make one of them cutting edge be in operating position, the cutter arbor rotation drives the blade rotation, the blade is close to the work piece after, to work piece outer wall milling process, long-term work back, this cutting edge wearing and tearing are serious back, pull down the blade and rotate 90, make another cutting edge be in operating condition, the cutter can normally work, can not lead to whole sword to scrap, whole blade all scrap the back, directly trade new blade can, the life of cutter has been prolonged. Meanwhile, the blade and the cutter bar are detachably connected, and the cutter bar is not made of hard alloy, so that the production cost of the cutter is reduced.
Preferably, the included angle between two adjacent cutting edges is 90 degrees, the inner diameter of the central hole is 4.2mm, and the upper end of the central hole is provided with a 60-degree relief opening.
By adopting the technical scheme, the integral rigidity of the blade is ensured, the blade is convenient to mount, and the structural rationality is improved.
Preferably, the relief angle of the insert is 11 °.
Through adopting above-mentioned technical scheme, with the help of the improvement of the whole rigidity of blade, can increase the relief angle of blade, improved the sharpness of cutting edge.
Preferably, two ends of the groove bottom of the cutting edge are respectively provided with 90-degree arc surfaces with the radius of 0.8 mm.
By adopting the technical scheme, the groove shape of the cutting edge has no sharp corner, the stress is not concentrated when the cutting edge works, the cutting edge is not easy to break, the abrasion of the cutting edge is reduced, and the service life of the blade is further prolonged. Meanwhile, the arc groove type also facilitates the chips to leave, and the chips are prevented from being accumulated at the groove bottom to aggravate the abrasion of the cutting edge.
Preferably, the cutting edge of the cutter is passivated, and the radius of the cutting edge of the cutter is 0.02-0.05 mm.
By adopting the technical scheme, when the passivated cutting edge is contacted with a workpiece, the contact area is large, the stress of the cutting edge is not concentrated, the cutting edge is not easy to break, and the service life of the cutter is further prolonged.
To sum up, the utility model discloses following effect has been gained:
1. by means of the cooperation of the four cutting edges, the service life of the cutter is prolonged.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
Example (b): an indexable contour insert for machining stainless steel is shown in fig. 1 and 2 and comprises a square cutter body 1, wherein cutting edges 2 are respectively arranged on four sides of the cutter body 1, the cutting edges 2 are arranged in a concave shape, each cutting edge 2 comprises two first cutting lines 21 with the length of 3.25mm, a second cutting line 22 with the length of 7.5mm is arranged between the two first cutting lines 21, the edges of the first cutting lines 21 are rounded, and a center hole 3 matched with a cutter bar penetrates through the middle of the cutter body 1 in the thickness direction.
Fix the blade on the cutter arbor through centre bore 3, make one of them cutting edge 2 be in operating position, the cutter arbor rotation drives the blade rotation, the blade is close to the work piece after, to work piece outer wall milling process, long-term work back, this cutting edge 2 wearing and tearing are serious after, pull down the blade and rotate 90, make another cutting edge 2 be in operating condition, the cutter can normally work, can not lead to whole sword to scrap, whole blade all scrap the back, directly trade new blade can, the life of cutter has been prolonged.
