The content of the invention
Technical problem solved by the invention is to provide a kind of flushing device of combination one of processing screw, to solve tradition Old-fashioned one rushes high replacement cost, delay production time, the problem of high cost.
For solve above-mentioned technical problem, the present invention using it is a kind of processing screw the flushing device of combination one, including one punching and Thimble a, it is characterised in that punching and thimble are Detachable connection structure;It is described one punching include hot-work die outer steel shell with Little wolfram steel one is rushed;The thimble includes white steel thimble and wolfram steel thimble;The inner surface and little wolfram steel of the hot-work die outer steel shell The outer surface gap of one punching coordinates, and hot-work die outer steel shell and the punching of little wolfram steel one are column type;The white steel thimble and wolfram steel Thimble is elongate cylinder build, the diameter of white steel thimble and the equal diameters of wolfram steel thimble maximum cylinder.
Further, into column type, end surface forms a groove, other end rat to the hot-work die outer steel shell One column type alignment pin, the circular hole that the inside of hot-work die outer steel shell offers forms accommodating chamber, and alignment pin prolongs into accommodating chamber Stretch certain length.
Further, the outer surface of the punching of little wolfram steel one coordinates with the internal surface gaps of hot-work die outer steel shell, little tungsten More than the perforate depth of hot die steel inside the shell, little wolfram steel one is rushed the length of the punching of steel one and receiving cavity gap coordinates, little wolfram steel One end of one punching is provided with the forming cavity of processing screw wire rod, in the punching of little wolfram steel one insertion hot-work steel shell circular hole and solid when using It is fixed, screw raw material wire rod can be processed into required screw product.
Further, the outer surface of the punching of little wolfram steel one is also provided with locating slot, and alignment pin is used cooperatively with locating slot, can be prevented Little wolfram steel one is punched in impact process and is carried over outside accommodating chamber.
Further, the thimble includes white steel thimble and wolfram steel thimble, and the diameter of white steel thimble is maximum with wolfram steel thimble The equal diameters of cylinder, the end of wolfram steel thimble is slender type impact portion, between the forming cavity in impact portion and the punching of little wolfram steel one Gap coordinates, the end of the white steel thimble and maximum cylinder of wolfram steel thimble is relative connects together when using.
Further, a punching and thimble are used cooperatively, and wire rod is processed into screw, thimble ejection shaping spiral shell by a punching Nail.
Compared with prior art, the flushing device simple structure of combination one, easy to use, the Jiang Yichong of present invention processing screw Separable two parts are divided into thimble, a punching abrasion in production process need to only change above little wolfram steel one and rush part, a punching Thimble abrasion also need to only change above wolfram steel thimble part, greatly save production cost, improve production efficiency.
【Description of the drawings】
Fig. 1 is the dimensional structure diagram of the flushing device of combination one of processing screw of the present invention.
【Specific embodiment】
Refer to shown in Fig. 1, a kind of flushing device of combination one of processing screw, including a punching and thimble, it is characterised in that it is described One punching and thimble are Detachable connection structure;One punching includes hot-work die outer steel shell 1 and the punching of little wolfram steel one 2;The top Pin includes white steel thimble 3 and wolfram steel thimble 4;Between the inner surface of the hot-work die outer steel shell 1 and the outer surface of the punching of little wolfram steel one 2 Gap coordinates, and hot-work die outer steel shell 1 and the punching of little wolfram steel one 2 are column type;The white steel thimble 3 and wolfram steel thimble 4 are carefully Long cylinder build, the diameter of white steel thimble 3 and the equal diameters of the maximum cylinder of wolfram steel thimble 4.
Refer to shown in Fig. 1,1 one-tenth column type of hot-work die outer steel shell, end surface forms a groove, another end surfaces are convex A column type alignment pin is played, the circular hole that the inside of hot-work die outer steel shell offers forms accommodating chamber, and alignment pin is into accommodating chamber Extend certain length.The outer surface of the punching of little wolfram steel one 2 coordinates with the internal surface gaps of hot-work die outer steel shell 1, the punching of little wolfram steel one 2 Length more than the perforate depth in hot-work die outer steel shell 1, the punching of little wolfram steel one 2 coordinates with cavity gap is accommodated, the punching of little wolfram steel one 2 One end be provided with the forming cavity of processing screw wire rod, when using, the punching of little wolfram steel one 2 is inserted in the circular hole of hot-work steel shell 1 and fixation, Screw raw material wire rod can be processed into required screw product.The outer surface of the punching of little wolfram steel one 2 is also provided with locating slot, alignment pin with Locating slot is used cooperatively, and the punching of little wolfram steel one 2 can be prevented to be carried over outside accommodating chamber in impact process.Thimble includes white steel thimble 3 With wolfram steel thimble 4, the diameter of white steel thimble 3 and the equal diameters of the maximum cylinder of wolfram steel thimble 4, the end of wolfram steel thimble 4 is Slender type impact portion, impact portion coordinates with the shaping cavity gap in the punching of little wolfram steel one 2, the end of white steel thimble 3 and tungsten when using The maximum cylinder of steel thimble 4 is relative to connect together.One punching and thimble are used cooperatively, and wire rod is processed into screw, thimble by a punching Ejection forming screw.
