Example 1
The precise composite punching die for hardware machining is shown in fig. 1-3, and comprises a base 1, guide cylinders 2 are connected to four corners of the top of the base 1, a female die seat 3 is connected between the guide cylinders 2 in a sliding mode, four first springs 4 are connected between the female die seat 3 and the guide cylinders 2, guide columns 5 are connected to four corners of the top of the female die seat 3, a male die seat 6 is arranged between the guide columns 5 in a sliding mode, the male die seat 6 and the female die seat 3 are matched to punch hardware, an adapter seat is connected to the top of the male die seat 6 and is used for being connected with a hydraulic cylinder or a telescopic end of a cylinder, and an ejection mechanism 7 for ejecting the punched hardware is arranged on the base 1.
As shown in fig. 1, fig. 2 and fig. 4, the ejector mechanism 7 comprises a pushing cylinder 71, the pushing cylinder 71 is mounted on the rear side of the base 1 through bolts, telescopic rods of the pushing cylinder 71 are arranged towards the upper direction, mounting brackets 72 are connected to the left side and the right side of the base 1, rotating plates 73 are connected to the mounting brackets 72, the rotating plates 73 are embedded into the die holders 3, rotating groove plates 74 are connected to the front side and the rear side of the rotating plates 73, two torsion springs 75 are connected between the rotating plates 73 and the adjacent mounting brackets 72, first connecting rods 76 are connected to the tops of the telescopic rods of the pushing cylinder 71, and the first connecting rods 76 are connected with the corresponding rotating groove plates 74 in a sliding and rotating mode.
It should be noted that, when the hardware is punched, the auxiliary operation can be realized by using the device, firstly, the hardware to be punched is placed on the die holder 3, then the adapter is connected with the cylinder or the telescopic end of the hydraulic cylinder, then the cylinder or the hydraulic cylinder is started to enable the male die holder 6 to move downwards along the guide post 5, so that the male die holder 6 can be meshed with the die holder 3, and thus the hardware punching operation is completed, in the punching process, the first spring 4 can effectively buffer the extrusion force received by the die holder 3, after the punching operation is completed, the male die holder 6 is controlled to reset, at this time, the pushing cylinder 71 is started, the telescopic rod of the pushing cylinder 71 is retracted downwards to drive the first connecting rod 76 to move downwards, so that the rotary groove plate 74 is rotated downwards, and then the rotary plate 73 is turned upwards, the torsion spring 75 is deformed under the force, the upward movement of the hardware which is completed is pushed to be separated from the die holder 3, so that an operator can conveniently and quickly take out the hardware, and then the first connecting rod 76 is pushed by the cylinder 71 to drive the reset, and the torsion spring 73 is driven to reset under the action of the rotary plate 75.
