Abstract
The utility model discloses a kind of high strength wolfram steel car pin, comprise the cutting head of being made by wolfram steel, the grip shank of being made by stainless steel, cutting head and grip shank are welded and fixed, cutting head comprises cutting head body, with the integrated connecting portion of cutting head body, connecting portion is tapered, the end of its large end face and grip shank is welded and fixed, by the bottom in cutting head body, extend to form the portion of being welded to connect, increase the bonding area of itself and grip shank, improve weld strength, and by pad toward moving down, make car pin when work, the bosom that pad is not cutting, when therefore even welding comes off, it can not jump out yet, only come off, reduced potential safety hazard.
Description
Technical field
The utility model relates to a kind of high strength wolfram steel car pin.
Background technology
Traditional welding, in working face head, weld, so pad is in working position, during due to Tool in Cutting, the power of bearing is all pointed out in welding, so weld there will be phenomenon of rupture, during cutter High Rotation Speed, cutting head very easily jumps out, cause danger, in addition because pad is total in working face, so cannot guarantee that working face all has cutting power, affects result of use.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of high strength wolfram steel car pin is provided, and has increased bonding area, improves weld strength, solves potential safety hazard.
For achieving the above object, the technical solution of the utility model is a kind of high strength wolfram steel car pin of design, comprise the cutting head of being made by wolfram steel, the grip shank of being made by stainless steel, described cutting head and described grip shank are welded and fixed, described cutting head comprise cutting head body, with the described integrated connecting portion of cutting head body, described connecting portion is tapered, and the end of its large end face and described grip shank is welded and fixed.
As preferably, on the solder side of described connecting portion, offer locating hole, formation locating dowel protruding upward on the solder side of described grip shank, described locating hole matches with described locating dowel.
As preferably, described locating hole is positioned at the center of described connecting portion, and described locating dowel is positioned at the center of described grip shank.
Advantage of the present utility model and beneficial effect are: by the bottom in cutting head body, extend to form the portion of being welded to connect, increase the bonding area of itself and grip shank, improve weld strength, and toward moving down, make car pin when work, the bosom that pad is not cutting pad, when therefore even welding comes off, it can not jump out yet, and only comes off, and has reduced potential safety hazard.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of cutting head;
Fig. 3 is the schematic diagram of grip shank.
In figure: 1, cutting head body; 2, grip shank; 3, connecting portion; 4, locating hole; 5, locating dowel.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1-Figure 3, a kind of high strength wolfram steel car pin, comprise the cutting head of being made by wolfram steel, the grip shank 2 of being made by stainless steel, described cutting head and described grip shank 2 are welded and fixed, described cutting head comprises cutting head body 1, with the described integrated connecting portion 3 of cutting head body 1, described connecting portion 3 is tapered, the end of its large end face and described grip shank 2 is welded and fixed, by the bottom in cutting head body 1, extend to form the portion of being welded to connect 3, increase the bonding area of itself and grip shank 2, improve weld strength, and by pad toward moving down, make car pin when work, the bosom that pad is not cutting, when therefore even welding comes off, it can not jump out yet, only come off, reduced potential safety hazard.
As shown in FIG. 2 and 3, on the solder side of described connecting portion 3, offer locating hole 4, formation locating dowel 5 protruding upward on the solder side of described grip shank 2, described locating hole 4 matches with described locating dowel 5, described locating hole 4 is positioned at the center of described connecting portion 3, and described locating dowel 5 is positioned at the center of described grip shank 2.During due to cutting head before and grip shank 2 welding, it is all plane-welding, owing to not locating, concentricity after welding is poor, and its weld strength is also unstable, very easily occurs obscission, by increase locating hole 4 on connecting portion 3, in grip shank 2, increase locating dowel 5, by coordinating of locating hole 4 and locating dowel 5, the concentricity while improving welding, improve the quality of products, and increased safety coefficient.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
