Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of punch die, especially relates to a blanking mechanism of punch die cooperation. BACKGROUND

[0002] The punch die is a kind of processing equipment for exerting pressure on metal plate, which can make metal plate produce plastic deformation, so as to obtain the workpiece of required shape and size.In the conventional die production line, the blanking and feeding process are generally completed by suction cup mechanism capable of moving X, Y and Z axes.Therefore, when blanking and feeding, it is necessary to wait for the completion of blanking before feeding, which leads to low production efficiency.

[0009] Based on the above technical solution, the utility model realizes the following beneficial effects:

[0010] 1, since steel belt passes through punch die, therefore, when receiving reel rolls steel belt, it can feed the metal material to be pressed (i.e.a certain part on steel belt) into punch die, and take out stamping product from punch die, realize that no carrying mechanism can realize blanking and feeding, simultaneously, it can realize blanking and feeding simultaneously, thereby improve production efficiency;

[0011] 2、In the blanking, because the stamping product needs to keep the local part not to be stamped to separate from the steel strip (that is, the stamping product has a local part adhered to the steel strip), the take-up reel can pull the take-up steel strip to take out the stamping product from the stamping die, therefore, when the steel strip takes out the stamping product from the stamping die and is located below the impact head, the crane module lifts the counterweight, then the crane module releases the counterweight, the counterweight pushes the impact head to impact the stamping product from the steel strip by gravity, thereby completing the material removal;

[0012] 3、Because the counterweight is connected with the impact head through the spring, when the impact head impacts the stamping product by gravity, the spring can buffer the impact force of the impact head and the stamping product in the instant of contact, and because the counterweight pushes the impact head to impact by its own gravity, the impact head and the counterweight can move upward freely, thereby buffering the reaction force generated in the instant of contact between the impact head and the stamping product, so that when the impact head impacts the stamping product, the impact head can avoid releasing all the impact force on the stamping product in the instant, thereby protecting the stamping product.

[0016] In some embodiments, a lead screw module is arranged above the support frames, and a fixed pressing plate is driven by the lead screw module, and the fixed pressing plate is used to close the support frames to clamp and fix the steel strip;

[0017] Based on the above technical scheme, when the impact head impacts the stamping product by gravity, the fixed pressing plate is driven by the lead screw module to close the support frames to clamp and fix the steel strip, so as to completely slow down the stress load of the material supply reel and the take-up reel, and make the stamping product more stably separated from the steel strip.

[0018] In some embodiments, the material supply reel is provided with a material supply brake module, the stamping die includes an upper die module and a lower die module which can be closed to each other, the steel strip passes between the upper die module and the lower die module, the steel strip is a flexible steel strip, and the take-up reel is provided with a power module;

[0020] 1. When the steel belt is punched by the stamping die, the power module is used to drive the material collecting winding disc to loosen, so that the steel belt is bent and droops to the lower die set by its own gravity, thereby realizing that the metal material to be pressed (i.e. a part on the steel belt) is placed in the cavity of the lower die set;

[0021] 2. When the stamping product is taken out from the stamping die by the steel belt, the brake module is used to control the speed of the material feeding winding disc, and the power module is used to drive the material collecting winding disc to straighten the steel belt, so that the steel belt and the stamping product are separated from the lower die set and the upper die set, thereby realizing that the stamping product can be separated from the lower die set and the upper die set without setting the ejector pin system in the lower die set and the upper die set.

[0039] The power module 31 drives the material collecting and winding disc 3 to rotate, and the material collecting and winding disc 3 winds the steel band 2, at this time, the steel band 2 is pulled out from the material feeding and winding disc 1, so that a part of the steel band 2 moves to between the upper die set 61 and the lower die set 62. After that, the power module 31 is used to drive the material collecting and winding disc 3 to loosen, so that the steel band 2 is bent and droops to be attached to the lower die set 62 by its own gravity, so as to realize that the metal material to be pressed (i.e. a part of the steel band 2) is placed in the cavity of the lower die set 62. After that, the upper die set 61 and the lower die set 62 are closed to stamp the part of the steel band 2 to the stamping product 21, and then the upper die set 61 and the lower die set 62 are opened to reset. After that, the brake module is used to control the speed of the material feeding and winding disc 1, the power module 31 drives the material collecting and winding disc 3 to rotate again, and the material collecting and winding disc 3 winds the steel band 2 again, at this time, the steel band 2 is straightened and separated from the lower die set 62 and the upper die set 61, and then the movement of the steel band 2 drives the stamping product 21 to move out from between the upper die set 61 and the lower die set 62 to below the impact head 43, and another part of the steel band 2 is synchronously moved to between the upper die set 61 and the lower die set 62 to wait for stamping. After that, the motor 45 drives the winding disc 44 to release the lifting wire 47, at this time, the counterweight 41 pushes the impact head 43 to impact the stamping product 21 by gravity, so that the stamping product 21 is separated from the steel band 2 and falls into the collecting box 53; then the motor 45 drives the winding disc 44 to wind the lifting wire 47, and the lifting wire 47 pulls the counterweight 41 and the impact head 43 to rise and reset.
