Detailed Description
Referring to fig. 1 to 2, a specific structure of a preferred embodiment of the present invention is shown, which includes a die steel body 10 and a tungsten steel punch 20.
The front end surface of the die steel body 10 is concavely provided with a welding groove 101 with a forward opening, in this embodiment, the die steel body 10 is die steel, but may be other steel materials. One end of the tungsten steel punch 20 is a welding part 21, the other end of the tungsten steel punch 20 is a punch part 22, the welding part 21 is inserted into the welding groove 101 to be positioned and welded and fixed with the die steel body 10, and the punch part 22 extends out of the welding groove 101. Through inserting welding portion 21 in welding groove 101, weld portion 21 and die steel main part 10 welded fastening again, compare traditional plane welding, die steel main part 10 and tungsten steel drift 20's welded structure intensity is stronger, and fixes a position in advance through welding groove 101, welds more convenient.
In the embodiment, the welding groove 101 is located in the center of the front end surface of the die steel main body 10, and the opening of the welding groove 101 gradually decreases toward the inner end, so that during soldering, the tin can conveniently flow into the welding groove 101 from the opening of the welding groove 101, and the welding part 21 can be completely welded with the die steel main body 10; meanwhile, the tin at the opening of the welding groove 101 is more than the tin at the inner end of the welding groove 101, the opening of the welding groove 101 is close to the punch part 22, when the punch part 22 punches, the stress at the opening of the welding groove 101 is large, and the welding structural strength between the opening of the welding groove 101 and the tungsten steel punch 20 is effectively enhanced through large-area tin solder at the opening of the welding groove 101.
And the tungsten steel punch 20 has a diameter smaller than that of the die steel body, and the tungsten steel punch 20 has a length shorter than that of the die steel body. In this way, the die steel body 10 is used as the main material component of the whole punch, while the tungsten steel punch 20 uses only a small amount of material, thereby effectively reducing the cost. By adopting two materials to manufacture the punch, namely the die steel main body 10 and the tungsten steel punch 20, and welding the two materials, the defect that the whole die steel punch is not durable is overcome, and the defect that the whole tungsten steel punch is high in cost is overcome.
In this embodiment, the die steel body 10 is a solid steel material having a cylindrical structure, and the tungsten steel punch 20 is also cylindrical. It should be noted that, in other applications, the die steel body and the tungsten steel punch may have other shapes, which is not limited by the attached drawings. Furthermore, the rear end of the die steel main body 10 is radially expanded to extend out to form an annular mounting portion 11 for being mounted with the punching die connecting component, and the annular mounting portion 11 is provided with a positioning notch 102 for being connected with the punching die connecting component, so that the mounting mode can refer to the utility model patent of the punching position adjusting device applied in 2017, 4, 28, and the patent number is 2017204674214.
The utility model discloses a welding drift, its manufacture process as follows: taking a tungsten steel punch 20, inserting one end (namely a welding part) of the tungsten steel punch 20 into the welding groove 101 for positioning, soldering the welding part 21 inserted into the welding groove 101, welding the welding part 21 into the welding groove 101, wherein in the soldering process, tin flows into the inner end of the welding groove 101 along the opening of the welding groove 101 to realize full welding, so that the tungsten steel punch 20 and the die steel body 10 are combined into a whole.
The utility model discloses a design focus lies in: firstly, through the concave welding groove that is equipped with on the preceding terminal surface of mould steel main part, during the weld part of tungsten steel drift inserted the welding groove, with weld part and mould steel main part welded fastening again, compare traditional plane welding, the welded structure intensity of mould steel main part and tungsten steel drift is stronger, and fixes a position in advance through the welding groove, welds more convenient. Secondly, the welding groove is designed to be of a structure that the opening gradually reduces towards the inner end, so that tin can conveniently flow into the welding groove from the opening of the welding groove during tin soldering, and the soldering part can be comprehensively soldered with the die steel main body; meanwhile, the tin at the opening of the welding groove is more than that at the inner end of the welding groove, and because the opening of the welding groove is close to the punch part, when the punch part punches, the stress at the opening of the welding groove is larger, and the welding structural strength between the opening of the welding groove and the tungsten steel punch is effectively enhanced through large-area tin soldering at the opening of the welding groove.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
