Description

Elastic tripper in automobile terminal high-speed precise punching die
Technical field
The present invention relates to a kind of device for discharging of diel, the elastic tripper particularly in a kind of automobile terminal high-speed precise punching die.
Background technology
Along with the fast development of auto industry and IT industry, automobile terminal is not only high to appearance requirement and volume requirement is also little, simultaneously to the quality of terminal also in raising, therefore to diel manufacturing technology difficulty and Structural Design Requirement many.Automobile terminal belongs to miniature precision stamping parts and terminal product dimensional accuracy, positioning requirements is higher, terminal material uses punching performance and forming stability good material to be brass or phosphor bronze, be divided into the material strip of different in width through coiled strip, material strip is shaped through multiple working procedures such as high-speed precise punching die punching, stamping and blanking, impression, continuous bend, shapings.Therefore rational shaping order and stable carrier Layout Design and reliable mould structure are the prerequisites guaranteeing terminal Forming Quality.
Device for discharging is very important part in stamping continuous die, it not only plays discharging effect, also play correcting punch, flatten the effect of material, the device for discharging of current use is by arranging waste material nibs in one end of blanking punch, and discharging that one end and unloading block of being provided with the blanking punch of waste material nibs have been set-located, but when the product of production different model, waste material nibs is also different, then need blanking punch and the unloading block of changing different model simultaneously, make the quantity of the number needs of unloading block and blanking punch as many, add production cost, and often dismantle blanking punch and unloading block, increase production process and waste time and energy, reduce operating efficiency and production efficiency.
Summary of the invention
For the problem as many causing the high and frequent dismounting blanking punch of production cost and unloading block to cause production efficiency lower because of unloading block number needs and blanking punch occurred during production different model product in prior art, the invention provides the elastic tripper in a kind of automobile terminal high-speed precise punching die, this device can realize the requirement that a unloading block meets the part production of two different model waste material discharging nibs, reduce production cost and save operation, enhancing productivity.
For achieving the above object, the present invention is by the following technical solutions:
Elastic tripper in a kind of automobile terminal high-speed precise punching die, it comprises patrix and punch retainer, patrix is provided with elasticity unloading block, punch retainer is provided with blanking punch, described blanking punch comprises the first operative end surface and the second operative end surface, first operative end surface is provided with the waste material discharging nibs of relatively large number, and the second operative end surface is provided with the waste material discharging nibs compared with ting model; Described elasticity unloading block and the first operative end surface match, and elasticity unloading block is through being arranged on patrix and being connected with patrix through the plug plug screw of elastic component.
For meeting the requirement of elasticity discharging elasticity height, the operative end surface of described elasticity unloading block is higher than blanking punch first operative end surface 1 ~ 1.5mm.
For convenience of and quick position install with change blanking punch, described punch retainer is provided with pressing plate, elasticity unloading block is fixed by plug-in mounting mode, as long as pull down elasticity unloading block, can facilitate and take out blanking punch rapidly.
Described elastic component is Rectangular Spring, by regulating the precompression of Rectangular Spring, realizes the balance adjustment of pressure-plate-force.
The end of described first operative end surface is provided with step, ensures elasticity discharging height by step dimension.
Compared with prior art, the present invention has following advantage: 1. need not dismantle elasticity unloading block by spinning upside down the different operating end face of blanking punch, realize the requirement that a unloading block meets the part production of two different model waste material discharging nibs, structure is simple, easy to use; 2. effectively reduce the production quantity of elasticity unloading block, thus reduce production cost; 3. save operation and time saving and energy saving, enhance productivity simultaneously.
Accompanying drawing explanation
Fig. 1 is modular construction schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, elastic tripper in present embodiment in automobile terminal high-speed precise punching die, it comprises patrix 1 and punch retainer 3, patrix is provided with elasticity unloading block 5, punch retainer is provided with blanking punch 8, and described blanking punch 8 comprises the first operative end surface and the second operative end surface, and the first operative end surface is provided with the waste material discharging nibs of relatively large number, and being provided with step in the end of the first operative end surface, the second operative end surface is provided with the waste material discharging nibs compared with ting model; Described elasticity unloading block and the first operative end surface match, and elasticity unloading block is through being arranged on patrix and being connected with patrix through the plug plug screw 7 of elastic component 6.
For ensureing elasticity discharging elasticity height, the operative end surface of described elasticity unloading block is higher than arbitrary numerical value in blanking punch first operative end surface 1mm, 1.2mm, 1.5mm or 1 ~ 1.5mm.
As preferably of the present invention, for convenience of and quick position install with change blanking punch, described punch retainer is provided with pressing plate, elasticity unloading block is fixed by plug-in mounting mode, as long as pull down elasticity unloading block, can facilitate and take out blanking punch rapidly.
As present invention further optimization, elastic component is Rectangular Spring, by regulating the precompression of Rectangular Spring, realizes the balance adjustment of pressure-plate-force.
As of the present invention further preferred, the end of the first operative end surface is provided with step, ensures elasticity discharging height by step dimension.
The course of work of the present invention is as follows:
When using the first operative end surface of blanking punch, first the first operative end surface of blanking punch inserted in punch retainer, then elasticity unloading block is penetrated blanking punch, elasticity unloading block and blanking punch are all fixed with different pressing plates; When using the second operative end surface of blanking punch, blanking punch is disassembled upset, then the second operative end surface of blanking punch is inserted in punch retainer, then elasticity unloading block is penetrated blanking punch, elasticity unloading block and blanking punch are all fixed with different pressing plates, elasticity unloading block need not be dismantled by spinning upside down the different operating end face of blanking punch, realize the requirement that a unloading block meets the part production of two different model waste material discharging nibs, structure is simple, easy to use, decreases processing quantity and the production cost of elasticity stripper simultaneously.
