Description
Technical field
The utility model relates to a kind of punching die.
Background technology
The structure of general diel is: patrix installs pierce punch, and counterdie installs punching concave die, and after punching, the waste material of product is directly discharged from counterdie, and because different product structures is different, many products cannot use conventional structure to produce.Chinese patent application CN201410131304.1 discloses a kind of diel, comprises upper bolster; Die block, die block is located on the lower surface of upper bolster; Die, die is located on the lower surface of die block; Holding pad, holding pad is located at the below of die; Die shoe, die shoe is located at the below of holding pad; Punch, punch is located on holding pad, and punch is positioned at the top of die shoe and is positioned at the below of die; Actuator, actuator is located on the upper surface of holding pad; With locking pushing block, locking pushing block is located at the upper surface of holding pad and is connected with actuator.This die upper, punch under the shortcoming of diel be: during punching, waste material, cannot normal discharge in patrix, needs to use special discharge apparatus to carry out discharge, uses inconvenience and cost is high.
Summary of the invention
In order to overcome existing die upper, punch under diel there is punching time discharge need to use the shortcoming of special discharge apparatus, the utility model provide a kind of can the punching die of automatic discharge.
A kind of punching die, comprise upper bolster, die shoe and patrix driving mechanism, upper bolster is fixed with punching concave die, and die shoe is fixed with piercing punch, and punching concave die is mated with piercing punch; It is characterized in that: piercing punch axially offers the discharging channel of waste discharge material, punching concave die is connected with corresponding die holder by respective pusher with piercing punch, upper pusher is primarily of the upper scraping wings of annular and upper spring composition, upper spring connects upper scraping wings and upper bolster, and upper scraping wings is socketed in the hole of punching concave die; Upper bolster is fixed with waste material stretching convex die, waste material stretching convex die is inserted and is gone up in scraping wings and aim at discharging channel.
Further, lower pusher is primarily of lower scraping wings and lower spring composition, lower scraping wings offers the through hole allowing piercing punch to run through, lower scraping wings is supported by lower spring, lower spring is set on guide rod, guide rod be fixed on die shoe, the other end through lower scraping wings and with lower scraping wings matched in clearance, guide rod top is provided with locating part.
In use, first die sinking, is enclosed within workpiece on piercing punch the utility model, now, lower scraping wings holding workpiece.Mould matched moulds, after upper scraping wings touches workpiece, upper and lower scraping wings is stressed, and upper spring and lower spring are compressed, until workpiece touches punching concave die and piercing punch simultaneously.It is descending that stamping machine makes upper bolster continue, and punching concave die and piercing punch acting in conjunction complete punching.Then, upper bolster continue descending, waste material stretching convex die touches waste material, and press down waste material make it distortion, enter in discharging channel, waste material relies on own wt to drop after entering discharging channel, realizes discharge.
The utility model has the advantage of: can die upper male mould under when realize the automatic discharge of punched scrap, without the need to being equipped with special discharge apparatus, thering is no unnecessary station, reducing costs.

Fig. 2 is the schematic diagram of workpiece when simultaneously touching punching concave die and piercing punch.
Fig. 3 is the schematic diagram of punching when completing.
Fig. 4 is the schematic diagram that waste material stretching convex die stretching waste material enters discharging channel.
Detailed description of the invention
As Figure 1-4, a kind of punching die, comprises upper bolster 1, and die shoe 2 and patrix driving mechanism, upper bolster 1 is fixed with punching concave die 3, and die shoe 2 is fixed with piercing punch 4, and punching concave die 3 is mated with piercing punch 4; Piercing punch 4 axially offers the discharging channel 41 of waste discharge material, punching concave die 3 is connected with corresponding die holder by respective pusher with piercing punch 4, upper pusher forms primarily of the upper scraping wings 51 of annular and upper spring 52, upper spring 52 connects upper scraping wings 51 and upper bolster 1, and upper scraping wings 51 is socketed in the hole of punching concave die 3; Upper bolster 1 is fixed with waste material stretching convex die 6, waste material stretching convex die 6 is inserted and is gone up in scraping wings 51 and aim at discharging channel 41.
Lower pusher forms primarily of lower scraping wings 71 and lower spring 72, lower scraping wings 71 offers the through hole allowing piercing punch 4 to run through, lower scraping wings 71 is supported by lower spring 72, lower spring 72 is set on guide rod, guide rod be fixed on die shoe 2, the other end through lower scraping wings 71 and with lower scraping wings 71 matched in clearance, guide rod top is provided with locating part.
In use, first die sinking, is enclosed within piercing punch 4 the utility model by workpiece, now, lower scraping wings 71 holding workpiece A.Mould matched moulds, after upper scraping wings 51 touches workpiece A, upper and lower scraping wings 71 is stressed, and upper spring 52 and lower spring 72 are compressed, until workpiece A touches punching concave die 3 and piercing punch 4 simultaneously.It is descending that stamping machine makes upper bolster 1 continue, and punching concave die 3 and piercing punch 4 acting in conjunction complete punching.Then, upper bolster 1 continues descending, and waste material stretching convex die 6 touches waste material, and presses down waste material and make it distortion, enter in discharging channel 41, and waste material enters after discharging channel 41 and relies on own wt to drop, and realizes discharge.
The utility model has the advantage of: can die upper male mould under when realize the automatic discharge of punched scrap; without the need to being equipped with special discharge apparatus; there is no unnecessary station; the content of falling described in this description embodiment is only enumerating the way of realization that utility model is conceived; protection domain of the present utility model should not be regarded as being only limitted to the concrete form that embodiment is stated, protection domain of the present utility model also and conceive the equivalent technologies means that can expect according to the utility model in those skilled in the art.
