Abstract
A female die for preventing waste from stacking comprises a female die arranged in the body of a bottom die and a female die bottom board on the bottom of the bottom die, wherein the female die has a cap-shaped inner cavity, and is provided with a punching hole on the top portion thereof. And an outlet is arranged on the female die bottom board. The female die preventing waste from stacking is characterized in that a suction port is arranged on the top portion of the female die. And one group of suction ports can be arranged on the top portion of the female die for smoothly discharging waste. Waste can be discharged smoothly without stacking as the female die is provided with the suction ports, and the method of using negative pressure and compressed air is used for discharging waste. The female die for preventing waste from stacking can be simply operated, has the characteristics of simple production process, long service life and low maintenance cost, can effectively discharge waste, and prevent waste from staking in the opening of the female die.
Description
Technical field
The utility model relates to mould in a kind of stamping technology, particularly relates to the cold punching die structure in a kind of vehicle cladding element punching technical field, and more particularly, the utility model relates to the anti-waste material packed structures of a kind of die.
Background technology
At present, the automobile body covering piece mould is to require the mould the highest, that difficulty of processing is maximum during body of a motor car is made, and also is the cold punching technology equipment that develops rapidly in China's electronic product manufacturing.The automobile body covering piece punching die generally uses die case, is convenient to maintain and replace like this.The punching concave die cover generally is installed in counterdie.In actual punching production process, scheduling of production all is more than hundreds of even thousands of parts, piercing punch and die in punching course, wear and tear generally all compare serious, so otherwise periodic replacement.Modern punching production all is automation pile line operation, and the waste material of trimming and piercing die mould is got rid of all strict requirement.The structure of the general die that uses, it comprises the die base plate that intrinsic die of counterdie and bottom are set.Described die has inner chamber to be hat, and the top is punching, and the inner chamber outlet is drawn waste material with negative pressure.Because die does not have air inlet, have only negative pressure to draw waste material, be easy to cause punched scrap to be deposited in the punching of die mouth.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the existing die, and the die that provides a kind of anti-waste material to pile up makes the waste material in the punching of die mouth realize smooth and easy discharge.
To achieve these goals, the utility model solves the technical scheme that its technical problem adopts and is: the die that a kind of anti-waste material is piled up, it comprises the die base plate that intrinsic die of counterdie and bottom are set.Described die has inner chamber to be hat, and the top is punching.The die base plate has discharging opening.It is characterized in that: air admission hole is set at the die top.
In order to make waste material realize smooth and easy discharge, the air admission hole that described die top is provided with can be one group.
Good effect of the present utility model: because the structure of air inlet is offered in employing on die case, use negative pressure and compressed-air actuated method to discharge waste material, the effect of discharging waste material than no air inlet structure is good, makes to get rid of the smooth and easy nothing accumulation of waste material.Make the utility model easy and simple to handle, characteristics such as have that manufacturing process is simple, long service life, maintenance cost are low can effectively be discharged waste material, prevent that waste material is deposited in the die mouth.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 analyses and observe organigram for the utility model.
Among the figure: 1. descend mould body, 2. die, 3. die base plate, 4. punching, 5. discharging opening, 6. air admission hole.
The specific embodiment
As shown in Figure 1, the die that a kind of anti-waste material is piled up, it comprises the interior die 2 of mould body 1 and the die base plate 3 of bottom is set down.Described die 2 has inner chamber to be hat, and the top is punching 4.Die base plate 3 has discharging opening 5.At die 2 tops air admission hole 6 is set.
In order to make waste material realize smooth and easy discharge, the air admission hole 6 that described die 2 tops are provided with can be one group.
When punched scrap was cumulative in matrix cavity, vavuum pump was drawn air and is made the certain vacuum of generation in the matrix cavity, and this has just produced negative pressure; Because air admission hole and atmosphere communicate, certain pressure has been given birth in the sell of one's property, and beginning compressed air has just produced air-flow like this in the matrix cavity, makes and gets rid of very smooth and easy that waste material becomes.Compare with no air inlet structure die, under powerful air-flow, discharge is very effective.
Adopt above-mentioned technical scheme, make the utility model easy and simple to handle, have simple, the use of manufacturing process The characteristics such as the life-span is long, maintenance cost is low can effectively be discharged waste material, prevent that waste from stacking is in the die mouth. This can satisfy the difficult problem that waste material is got rid of in the modern punching production process to a great extent, effectively improves Production efficiency.
