Abstract

The utility model relates to a punch die, which mainly and structurally comprises an upper die, a lower die and a punch head, wherein the lower die consists of a lower template, a lower base plate and a lower die holder which are overlapped in sequence from top to bottom; a female die with two cutting edges is embedded into the lower template; and the cutting edges on the female die are arranged symmetrically. In the production process, one cutting edge of the female die is used for continuously grinding the punch head; when the cutting edge is worn, only the female die is required to be rotated by 180 degrees, and a new cutting edge can be used for continuously grinding the punch head, so that the equipment maintaining time is greatly reduced; and when both of the two cutting edges on the female die are worn, working personnel needs to stop a machine and take the female die and the punch head down for grinding. Due to the adoption of the punch die, the grinding time of the female die is greatly saved, the maintenance period of equipment is prolonged, and the production efficiency of the equipment is improved.

Description

A kind of punching machine mold

Technical field

The utility model relates to a kind of five metals process equipment, particularly a kind of punching machine mold.

Background technology

Punch press is when the processing Hardware fitting, and is just sharp inadequately in the product back punching head of punch press production some owing to rubbing between drift and the mould, drift need be taken out and grind.Existing punch press is provided with an abradant cutting edge on the counterdie of being everlasting, can grind drift automatically in process of production, uses after a period of time to pull down drift again and cutting edge grinds after drift and cutting edge all wear and tear.The set-up mode of this punching machine mold of prior art can prolong the maintenance period of equipment, but its maintenance period can't adapt to now fast, continue the requirement of production.Still need frequent shutdown to pull down drift in process of production and cutting edge grinds.

The technical disadvantages that prior art exists is frequently to grind drift and cutting edge, reduces production efficiency of equipment greatly;

In sum: be badly in need of at present a kind ofly improving production efficiency of equipment, prolong the energy-conservation diel in plant maintenance cycle.

The utility model content

Technical problem to be solved in the utility model is the shortcoming that the mould of present employed punch die lathe exists, and redesigns a kind of punching machine mold.

The utility model is achieved through the following technical solutions above-mentioned purpose:

Technical disadvantages at the structure of existing punching machine mold exists designs a kind of punching machine mold, and its primary structure comprises upper die and lower die and drift.Described counterdie is made up of lower bolster, lower bolster and die shoe; Described lower bolster, lower bolster and die shoe are by stacked successively under last; Be nested with a die that has two cutting edges on the described lower bolster; Cutting edge on the described die is symmetrical arranged.The cutting edge of this mould die in process of production continues drift is ground, and only die need be carried out 180 degree rotations when wearing and tearing appear in this cutting edge, and a new cutting edge can continue drift is ground.Significantly reduce the time of plant maintenance.When two cutting edges on the die all wore and tore, the staff just need shut down die and drift taken off and grind.

The nested mode of described lower bolster and die is that lower bolster is provided with a groove, and die is placed in the groove, and a cutting edge of described die is oppositely arranged with the drift that is placed in patrix.

Described patrix is made up of upper bolster, backing plate and cope match-plate pattern, and upper bolster, backing plate and cope match-plate pattern are stacked successively from top to bottom; Described drift is fixed on the cope match-plate pattern.

The utility model has been saved the die milling time greatly, has also prolonged the maintenance period of equipment simultaneously, has improved efficiency of equipment.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment one;

Fig. 2 is the structural representation of the die of the utility model embodiment one.

The specific embodiment

Embodiment one: as shown in Figure 1, primary structure of the present utility model comprises patrix 1, counterdie 2 and drift 3.Described counterdie 2 is made up of lower bolster 21, lower bolster 22 and die shoe 23; Described lower bolster 21, lower bolster 22 and die shoe 23 are by stacked successively under last.As shown in Figure 2, be nested with a die 4 that has two cutting edges 41 on the described lower bolster 23; Cutting edge 41 on the described die 4 is symmetrical arranged.

As shown in Figure 1, described lower bolster 23 is that lower bolster 23 is provided with a groove 24 with the nested mode of die 4, and die 4 is placed in the groove 24, and a cutting edge 41 of described die 4 is oppositely arranged with the drift 3 that is placed in patrix 1.

As shown in Figure 1, described patrix 1 is made up of upper bolster 11, backing plate 12 and cope match-plate pattern 13, and upper bolster 11, backing plate 12 and cope match-plate pattern 13 are stacked successively from top to bottom; Described drift 3 is fixed on the cope match-plate pattern 13.

As shown in Figure 1, 2, the cutting edge 41 of this mould die 4 in process of production continues drift 3 is ground, and only die 4 need be carried out 180 degree rotations when wearing and tearing appear in this cutting edge 41, and a new cutting edge 41 can continue drift 3 is ground.Significantly reduce the time of plant maintenance.When two cutting edges 41 on the die 4 all wore and tore, the staff just need shut down die 4 and drift 3 taken off and grind.The utility model has been saved die 4 milling times greatly, has also prolonged the maintenance period of equipment simultaneously, has improved efficiency of equipment.

Claims
