Abstract
The utility model relates to a stamping die with an elastic punch-cum-blanking die, which belongs to the field of dies. The utility model provides the stamping die with the elastic punch-cum-blanking die to solve the technical problems in the prior cold stamping die that workpieces are assembled and disassembled inconveniently, and the workpieces are bent easily and damaged during stamping as the cold stamping die adopts the rigid punch-cum-blanking die. An elastic cavity die and a lower return spring are arranged on a die holder; an elastic terrace die and an upper return spring are arranged on a punch holder. As the cavity die is elastic, when a punch slipper reaches an upper dead center, the elastic cavity die leaves the die holder. Therefore, the workpieces are assembled and disassembled conveniently. The cavity die moves downwards under the action of the elastic terrace die. Accordingly, the external wall of a pipe fitting is in contact with the die holder, thereby preventing the pipe fitting from being bent and deformed due to the gap between the pipe fitting and the die holder.
Description
Technical field
The utility model relates to a kind of punching press apparatus for shaping of metal parts, is specifically related to a kind of diel of small-sized tubular part.
Background technology
Present cold punching pressing mold generally adopts the moulding of rigid convex die, and existing punch-die mould all is that die is fixed on the die block, and the position of being close to die block on die is provided with the moulding locating hole.Though this mould can satisfy the station requirement of simple products, yet have the following disadvantages in the use: (1) is because die is to be fixed on the die block by screw or alignment pin, spacing between moulding locating hole and the die block is less, then the loading and unloading of inconvenient workpiece; (2) because the spacing between moulding locating hole and the die block is certain, this is just relatively harsh to the dimensional requirement of workpiece, promptly all need the necessary unanimity of wall thickness of the pipe fitting of machine-shaping, require the requirement of wall thickness greater than diel when the wall thickness of needs processing pipe fitting, then workpiece can not be put into the moulding locating hole, the pipe fitting that is different wall need be with different moulds, require the requirement of wall thickness less than diel when the wall thickness of needs processing pipe fitting, there is the gap between the outer wall of pipe fitting and the die block, in the process of punching press, bend easily, cause the damage of workpiece.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and the diel that a kind of workpiece loading and unloading is convenient, can be applicable to the small-sized tubular part of different wall is provided.
The purpose of this utility model is achieved through the following technical solutions:
Have the diel of elasticity punch-die in the utility model, include upper bolster, be fixed on punch retainer on the upper bolster, be fixed on punch and die shoe on the punch retainer, be fixed on the die block on the die shoe.Wherein be provided with the elasticity die on die block, following back-moving spring one end is connected with die block, and the other end is nested in the die lower end and is connected with it, and die is provided with the moulding reference column.Also be provided with the elasticity punch on punch retainer, upper reset spring one end is connected with punch retainer, and the other end is nested in elasticity punch upper end and is connected with it.
The coefficient of elasticity of used upper reset spring is greater than the coefficient of elasticity of following back-moving spring in the utility model.
Because the die in the utility model is the elasticity die, then when slider of punch during at top dead-centre, the elasticity die leaves die block, then workpiece loading and unloading is more convenient, effect lower cavity die at the elasticity punch moves downward, realize that the pipe fitting outer wall contacts with die block, avoided the problem that occurs bending and deformation at punching course owing to the pipe fitting that exists the gap to cause between pipe fitting and the die block, diel is applicable to the pipe fitting of different wall.
Description of drawings
Fig. 1 is when slider of punch structural representation of the present utility model during at top dead-centre.
Fig. 2 is when slider of punch structural representation of the present utility model during at bottom dead centre.
The specific embodiment
The diel that has the elasticity punch-die of the present utility model, include upper bolster 7, be fixed on punch retainer 1 on the upper bolster 7 by screw or alignment pin, be fixed on the punch 3 on the punch retainer 1, and die shoe 8, be fixed on die block 4 on the die shoe 8 by screw or alignment pin.Upper bolster 7 is provided with ball bearing guide bushing 9, and die shoe 8 is provided with ball guide pillar 10, and guide pillar 10 and guide pin bushing 9 are slidingly matched.On die block 4, be provided with elasticity die 5, following back-moving spring 11 1 ends and die block 4 welding, the other end be nested in die 5 lower ends and with its welding, level is provided with moulding reference column 6 on the die 5, on punch retainer 1, also be provided with elasticity punch 2, upper reset spring 12 1 ends are connected with punch retainer 1, and the other end is nested in elasticity punch 2 upper ends and is connected with it.
The coefficient of elasticity of multiple upper spring 12 is greater than the coefficient of elasticity of following back-moving spring 11 in the utility model.
Operation principle of the present utility model is as follows:
Flattening process with the copper pipe pressure line terminal is an example, its operation principle is as follows: when slider of punch during at top dead-centre, die 5 leaves die block 4, copper pipe is inserted on the moulding reference column 6, when slider of punch continues when descending, punch 2 at first contacts die 5, and the effect lower cavity die 5 at punch 2 moves downward simultaneously, straight punch 2 is realized the action that compresses of copper pipe to contacting with die block 4.At reaction lower punch 2 retractions of die block 4, punch 3 continues to move down, and contacts with copper pipe, finishes towards the punching course of fabrication hole, flattening during to bottom dead centre then.
Claims (2)
1. diel that has the elasticity punch-die, include upper bolster (7), be fixed on the punch retainer (1) on the upper bolster (7), be fixed on punch (3) and die shoe (8) on the punch retainer (1), be fixed on the die block (4) on the die shoe (8), it is characterized in that: on die block (4), be provided with elasticity die (5), following back-moving spring (11) one ends are connected with die block (4), the other end is nested in die (5) lower end and is connected with it, die (5) is provided with moulding reference column (6), on punch retainer (1), also be provided with elasticity punch (2), upper reset spring (12) one ends are connected with punch retainer (1), and the other end is nested in elasticity punch (2) upper end and is connected with it.
2. the diel that has the elasticity punch-die according to claim 1 is characterized in that: the coefficient of elasticity of upper reset spring (12) is greater than the coefficient of elasticity of following back-moving spring (11).
