Abstract
The utility model discloses a plunger chip which comprises a plunger part and a plunger chip part, wherein a stamping ring is sleeved on the periphery of the plunger chip part, and end faces of the stamping ring are parallel and level to end faces of the plunger chip part. According to the plunger chip, the stamping ring is sleeved on the periphery of the plunger chip part, the stamping ring can be made of hard alloy steel such as tungsten alloy and is high in hardness and good in abrasive resistance, so that the plunger chip can work continuously, added maintenance time caused by replacement of damaged plunger chips is reduced, and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of die member, especially a kind of drift.
Background technology
Drift also is formpiston or red needle, and it is divided into A type drift, T-shaped drift, special-shaped plunger chip etc. according to profile, and drift generally is mounted in the metal parts in the diel, is applied to contact with the direct of material, makes material generation deformation, cuts material.Because producing amount of heat with friction of workpiece, drift needs heat-resistant antifriction during the drift stamped workpieces, needs the ability punching press of greater impact power or thrusts workpiece because of drift again, and therefore, drift also needs good impact flexibility.The drift that is applied at present on the punch press is integrative-structure, if a certain position of drift is damaged when punching press, therefore so whole drift is just scrapped, and needs the expensive metal materials such as nickel, tungsten, molybdenum because make drift, causes the workpiece processing cost to improve.
The utility model content
Problem to be solved in the utility model just provides a kind of drift that can reduce use cost.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of drift, comprise jumper bar section and punch, and described punch periphery cover has the punching press ring, and the end face of described punching press ring is concordant with the end face of described punch.
Further, described punching press ring is connected with described punch interference fit.
Further, described jumper bar section and described punch adopt 45 steel to make.
Further, described punching press ring adopts tungsten alloy to make.
Further, be provided with heat dissipation channel in the described punch.
Further, described jumper bar section is provided with projection, and described punch is provided with groove, and described projection is inserted described groove, and screw passes projection and with groove jumper bar section is connected with punch.
The beneficial effects of the utility model: during drift work, so long as utilize the edge roundness of nose of punch to thrust workpiece, thereby this position is also the most fragile, the utility model puts the punching press ring in the punch periphery, and the punching press ring can adopt hard alloy steel to make, such as tungsten alloy, hardness is high, wearability good, so that but the drift continuous operation has reduced because changing and damaged the maintenance time that drift increases, improved operating efficiency; Jumper bar section and punch can adopt 45 comparatively cheap steel of price, reduce use cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is explained and illustrated:
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two;
The specific embodiment
The utility model provides a kind of drift, comprises jumper bar section and punch, and described punch periphery cover has the punching press ring, and the end face of described punching press ring is concordant with the end face of described punch.The punching press ring can adopt hard alloy steel to make, and such as tungsten alloy, hardness is high, wearability good, but so that drift continuous operation.
Be explained and illustrated below in conjunction with the accompanying drawing of the present embodiment technical scheme to the utility model embodiment, but following embodiment is preferred embodiment of the present utility model only, is not whole.Based on the embodiment in the embodiment, those skilled in the art belong to protection domain of the present utility model at lower other embodiment that obtains of the prerequisite of not making creative work.
Embodiment one:
With reference to Fig. 1, a kind of drift comprises jumper bar section 1 and punch 2, and described punch 2 periphery covers have punching press ring 3, and the end face of described punching press ring 3 is concordant with the end face of described punch 2.During manufacturing, punching press ring 3 is connected with described punch 2 interference fit, and connected mode can be: hot jacket, cold cover or machinery are pressed into etc.Jumper bar section 1 and described punch 2 adopt 45 steel to make, and reduce cost, and punching press ring 3 adopt tungsten alloy to make, and such as YG6 or YG6X, has good wearability and high rigidity, improve service life.
In the present embodiment, be provided with heat dissipation channel 4 in punch 2, heat dissipation channel 4 can pass into air or pass into the cooling gas/liquid, to the drift cooling, avoids drift to change because heating causes material property in use.
Embodiment two:
With reference to Fig. 2, punch 2 in the present embodiment is roughly the same with embodiment, and different is: jumper bar section 1 is provided with projection 11, and punch 2 is provided with groove 21, projection 11 is inserted in the grooves 21, and utilizes screw 5 to pass projection 11 to be connected with groove jumper bar section 1 is connected with punch 2.The present embodiment has changed the integrative-structure of original drift, becomes dismountable Split type structure, only bears axial force during owing to drift work, adopts further Cost reduction of Split type structure, and drift is changed also convenient.
By above-described embodiment, the purpose of this utility model is by in full force and effect having reached.The personage who is familiar with this skill should be understood that the utility model includes but not limited to the content of describing in accompanying drawing and the top specific embodiment.Any modification that does not depart from function and structure principle of the present utility model all will be included in the scope of claims.
Claims (6)
1. a drift comprises jumper bar section and punch, it is characterized in that: described punch periphery cover has the punching press ring, and the end face of described punching press ring is concordant with the end face of described punch.
