Abstract
The utility model relates to a mechanical treatment device, in particular to a punching die for a sheet metal component. The punching die for the sheet metal component comprises an upper die and a lower die, wherein the upper die comprises an upper die plate and a punch pin at the bottom of the upper die plate; the lower die comprises a lower die plate and a female die at the upper part of the lower die plate; a groove is formed in the female mould and is communicated with a passage used for discharging scraps generated during punching; the tops of the female die are arranged on two sides of the groove; sheet metal component fixing devices are arranged at the tops of the female die; each sheet metal component fixing device comprises an upper pressure plate and a lower pressure plate; the lower pressure plates are fixed with the tops of the female die; the upper pressure plates move towards or far away from the lower pressure plates under the action of cylinders connected to the tops of the upper pressure plates; the cylinders are connected with the female die through brackets. Both sides of the sheet metal component can be fixed accurately by the sheet metal component fixing devices, so that the accuracy of punching is remarkably improved. As the structure of the punch pin is designed reasonably, the service life of the punching die is remarkably prolonged.
Description
Technical field
The utility model relates to a kind of machinery processing apparatus, specifically relates to a kind of sheet metal component punching die.
Background technology
In the punching processing process of sheet metal component, the structure of punching die exists varied, but generally without sheet metal component fixture, only adopt the parts such as bolt that sheet metal component is fixed on to die top, when the shortcoming of this fixed form maximum is punching, sheet metal component is easily offset, and machining accuracy is lower.Meanwhile, existing punch structure is generally comparatively fragile, and service life is shorter.
Utility model content
For the technical problem existing in prior art, the purpose of this utility model is to provide a kind of sheet metal component punching die.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of sheet metal component punching die, comprise upper die and lower die, described patrix comprises cope match-plate pattern and is placed in the drift of cope match-plate pattern bottom, described counterdie comprises lower bolster and is placed in the die on lower bolster top, in described die, offer groove, described groove is connected with the passage that forms fragment discharge for discharging punching; The both sides that described die top is placed in groove are provided with sheet metal component fixture, described sheet metal component fixture comprises top board and lower platen, described lower platen and die top are fixed, described top board is by the cylinder action being connected with its top, make its pushing the back down one side near or away from, described cylinder is connected with die by support; Described drift comprises the first cone, the first cylinder, the second cylinder, three cylindrical body, the second cone, the 4th cylinder, Three-cone, the 5th cylinder, the 6th cylinder and the 7th cylinder that is global formation adjacent one another are;
Described the first cone, the first cylinder, the second cylinder, three cylindrical body, the second cone, the 4th cylinder, Three-cone, the 5th cylinder, the 6th cylinder and the 7th cylindrical Length Ratio are 1:1.5:0.3:0.5:1:1:1:1.5:0.3:0.5.
Sheet metal component punching die of the present utility model, its beneficial effect shows:
By sheet metal component fixture is set, is that the both sides of sheet metal component all obtain accurate fixing, and then significantly promotes the precision of punching processing.By the structure of appropriate design drift, is significantly improved its service life.
Accompanying drawing explanation
