In order to solve the problems of the technologies described above, remedy the deficiency that exists in the prior art, the composite die that the utility model provides a kind of moulding to hold concurrently punching comprises cope match-plate pattern, lower bolster and is arranged on the up stripper on the material, it is characterized in that:
Said cope match-plate pattern is provided with moulding drift, pierce punch, and the position of corresponding moulding drift is provided with molding concave die on the said lower bolster, and moulding drift inside is provided with a through hole, and said pierce punch is arranged in the above-mentioned through hole; Said moulding drift, pierce punch include jumper bar and are arranged on the cutter head of jumper bar lower end, the cutter head end face of pierce punch and the cutter head end face of moulding drift, and the inwall of moulding drift through hole is close in the cutter head side of pierce punch; Be provided with in the die mouth of said molding concave die and take off plate in the moulding, take off in the said moulding that the position of corresponding said pierce punch is provided with punching concave die on the plate.
Further technical scheme also comprises:
Said through hole is stepped, comprises lower through-hole that the pierce punch cutter head is set and the top through hole that the pierce punch jumper bar is set, and said lower through-hole is less than the top through hole; The jumper bar of said pierce punch is stepped; Comprise two sections; The diameter of its epimere is greater than the diameter of hypomere; The jumper bar epimere sidewall of pierce punch is close to the sidewall of said through hole, and the jumper bar hypomere of pierce punch and the gap between the said through hole are provided with back-moving spring, and said back-moving spring is against respectively on the jumper bar and through-hole wall of pierce punch at two ends up and down.
The jumper bar top of said pierce punch is provided with set screw, is used to control the range and the springback process of said back-moving spring.
Take off the plate bottom in the said moulding and be provided with elasticity reset device.
Said punching concave die bottom is provided with material-dropping hole.
The beneficial effect of the utility model is:
Novel structure is once accomplished the moulding of workpiece and punching, has improved production efficiency greatly, has saved the man power and material, and can satisfy the requirements of making of high-precision workpiece punching press.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the local structure for amplifying sketch map of the utility model.
The specific embodiment
For technical scheme and the technical purpose of illustrating the utility model, the utility model is done further introduction below in conjunction with the accompanying drawing and the specific embodiment.
As shown in the figure; The composite die that punching is held concurrently in a kind of moulding; Comprise cope match-plate pattern, lower bolster and be arranged on the up stripper 3 on the material, cope match-plate pattern is provided with moulding drift 1, pierce punch 2, and the position of corresponding moulding drift 1 is provided with molding concave die on the said lower bolster; Moulding drift 1 inside is provided with a through hole, and said pierce punch 2 is arranged in the above-mentioned through hole; Said moulding drift 1, pierce punch 2 include jumper bar and are arranged on the cutter head of jumper bar lower end, the cutter head end face of pierce punch 2 and the cutter head end face of moulding drift 1, and the inwall of moulding drift 1 through hole is close in the cutter head side of pierce punch 2; Be provided with in the die mouth of said molding concave die and take off plate 4 in the moulding, the position of taking off corresponding said pierce punch 2 on the plate 4 in the said moulding is provided with punching concave die 5, takes off plate 4 bottoms in the moulding and is provided with elasticity reset device, and punching concave die 5 bottoms are provided with material-dropping hole.
Said through hole is stepped, comprises lower through-hole that pierce punch 2 cutter heads are set and the top through hole that pierce punch 2 jumper bars are set, and said lower through-hole diameter is less than the top through hole; The jumper bar of said pierce punch 2 is stepped; Comprise two sections; The diameter of its epimere is greater than the diameter of hypomere; The jumper bar epimere sidewall of pierce punch 2 is close to the sidewall of said through hole, and the jumper bar hypomere of pierce punch 2 and the gap between the said through hole are provided with back-moving spring 6, and said back-moving spring is against respectively on the jumper bar outer wall and through-hole wall of pierce punch 2 at two ends about in the of 6.The jumper bar top of said pierce punch 2 is provided with set screw, is used to control the range and the resilience of back-moving spring 6, guarantees the stability of equipment.
