Abstract
The utility model relates to an efficient stamping die. The efficient stamping die comprises an upper die and a lower die which are vertically distributed, wherein the bottom of the upper die is provided with a plurality of guide columns which are distributed in a square shape, and the lower die is provided with corresponding casing pipes which are distributed in the square shape; both sides of the upper die are provided with mounting pieces, the middle of the bottom end of the upper die is provided with a square terrace die, and the middle of the lower die is provided with a cavity die; when the upper die moves close to the lower die, the guide columns are inserted into the casing pipes, and the terrace die is inserted into the cavity die; both ends of every guide column are provided with buffering pieces, and springs sleeve the buffering pieces; a plurality of balls are arranged between every guide column and a corresponding guide sleeve, one part of every ball is embedded inside the guide sleeve, and the other part of the ball is embedded inside the guide column. The efficient stamping die changes the sliding friction between the guide columns and the guide sleeves into rolling friction, thereby efficiency reducing friction and further reducing wearing of the guide columns and the guide sleeves; meanwhile, when the ends of the guide columns are under impact, the buffering pieces can buffer the impact force born by the guide columns to reduce the damage of the impact force to the guide columns and further prolong the service life of the guide columns.
Description
Technical field
The utility model relates to mould applications, relates in particular to a kind of efficient diel.
Background technology
Diel, is in Cold Press Working, material (metal or nonmetal) is processed into a kind of special process equipment of part (or semi-finished product), is called cold punching die (being commonly called as cold-punching mould).Punching press is at room temperature, utilizes the mould being arranged on forcing press to exert pressure to material, makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.
Between guide pillar in diel of the prior art and guide pin bushing, be sliding friction, the friction ratio that this mode produces is larger, easily causes the wearing and tearing between guide pillar and guide pin bushing; Simultaneously, in mould use procedure, the end of guide-post of die-set is subject to larger axial impact force conventionally, after being impacted of long period, easily makes guide-post of die-set generation deformation.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of efficient diel is provided.
The utility model is to be achieved through the following technical solutions:
A kind of efficient diel, has and goes to upper and lower the upper die and lower die of arranging, wherein, patrix bottom is provided with multiple guide pillars that are square and arrange, described counterdie is provided with the sleeve pipe that is square accordingly and arranges, and described patrix both sides are provided with installed part, and the middle part of patrix bottom is provided with the punch being square, counterdie middle part is provided with die, patrix to counterdie near time, guide pillar inserts in sleeve pipe, punch inserts in die, the both ends of described guide pillar are provided with bolster, on described bolster, are socketed with spring; Between described guide pillar and guide pin bushing, be provided with several balls, a part for described ball is embedded in guide pin bushing, and another part is embedded in guide pillar.
As optimal technical scheme of the present utility model, the quantity of described guide pillar is four, all has chamfering in the end of each guide pillar.
As optimal technical scheme of the present utility model, the material of described punch and die is grey black cast iron.
As optimal technical scheme of the present utility model, described bolster is that working of plastics is made.
Compared with prior art, the beneficial effects of the utility model are: the sliding friction between guide pillar and guide pin bushing is become rolling friction by the utility model, effectively reduces friction, reduce the wearing and tearing of guide pillar and guide pin bushing; While being subject to impacting in guide-post of die-set end, the impulsive force that bolster buffering guide-post of die-set is subject to, reduces the damage of impulsive force to guide-post of die-set, extends the service life of guide-post of die-set simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-patrix; 2-counterdie; 3-installed part; 4-guide pillar; 5-bolster; 6-spring; 7-guide pin bushing; 8-ball.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
The efficient diel of described one, have and go to upper and lower patrix 1 and the counterdie 2 of arranging, wherein, patrix 1 bottom is provided with multiple guide pillars 4 that are square and arrange, described counterdie 2 is provided with the sleeve pipe that is square accordingly and arranges, described patrix 1 both sides are provided with installed part 3, the middle part of patrix 1 bottom is provided with the punch being square, counterdie 2 middle parts are provided with die, patrix 1 to counterdie 2 near time, guide pillar 4 inserts in sleeve pipe, punch inserts in die, the both ends of described guide pillar 4 are provided with bolster 5, on described bolster 5, are socketed with spring 6; Between described guide pillar 4 and guide pin bushing 7, be provided with several balls 8, a part for described ball 8 is embedded in guide pin bushing 2, and another part is embedded in guide pillar 4.The sliding friction between guide pillar 4 and guide pin bushing 7 is become rolling friction by the utility model, effectively reduces friction, reduces the wearing and tearing of guide pillar 4 and guide pin bushing 7; While being subject to impacting in guide-post of die-set 4 ends, the impulsive force that bolster buffering guide-post of die-set is subject to, reduces the damage of impulsive force to guide-post of die-set, extends the service life of guide-post of die-set simultaneously.
The quantity of described guide pillar 4 is four, all has chamfering in the end of each guide pillar 4; The material of described punch and die is grey black cast iron, and described bolster 5 is made for working of plastics.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
