In the description of the present invention, it is to be understood that the terms "opening," "upper," "lower," "thickness," "top," "middle," "length," "inner," "peripheral," and the like are used in an orientation or positional relationship that is merely for convenience in describing and simplifying the description, and do not indicate or imply that the referenced component or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the present invention.

As shown in fig. 1-2, an automobile plate blanking device comprises: the device comprises a rack 1, a driving mechanism 2, an upper die 3 and a lower die 4, wherein the driving mechanism 2 and the lower die 4 are both fixedly installed on the rack 1, the upper die 3 is arranged between the driving mechanism 2 and the lower die 4, and the driving mechanism 2 drives the upper die 3 to move up and down, wherein the driving mechanism 2 is, for example, but not limited to, an air cylinder or a hydraulic cylinder; this device still includes: the connecting rod 5, the first piston rod 6, the second piston rod 7 and the cylinder body 8, the cylinder body 8 is embedded in the lower die 4, and the side surface and the upper end surface of the lower die 4 are respectively provided with a first sliding chute and a second sliding chute; the first piston rod 6 is connected with the lower die 4 in a sliding mode through a first sliding groove, one end of the first piston rod 6 is connected with one port of the cylinder body 8, and the other end of the first piston rod 6 is arranged outside the sliding groove; the second piston rod 7 is connected with the lower die 4 in a sliding mode through a second sliding groove, and one end of the second piston rod 7 is connected with the other end port of the cylinder body 8; one end of the connecting rod 5 is hinged with the upper die 3, and the other end of the connecting rod is hinged with the part of the first piston rod 6, which is positioned outside the first sliding chute; the first piston rod 6, the cylinder 8 and the second piston rod 7 form a sealed cavity inside the cylinder 8. And, the cylinder 8 is filled with hydraulic oil.

Specifically, when blanking is performed, a plate should be placed on the lower die 4, then the driving mechanism 2 is started, and the driving mechanism 2 drives the upper die 3 to move downwards to perform stamping and blanking. In the process that the upper die 3 moves downwards, the connecting rod 5 drives the first piston rod 6 to move outwards towards the first sliding groove, vacuum is formed in the cylinder body 8 at the moment, and the second piston rod 7 moves downwards and retracts into the second sliding groove under the atmospheric pressure. After the punching is finished, in the lifting process of the upper die 3, the connecting rod 5 drives the first piston rod 6 to slide in the first sliding groove, hydraulic oil in the cylinder body 8 is pushed by the first piston rod 6 to surge upwards to jack the second piston rod 7, and the second piston rod 7 jacks the semi-finished plate to separate the semi-finished plate from the lower die 4, so that the blanking of the plate is finished. That is, the blanking device for automobile plates of the invention can take out the blanked semi-finished plates without an additional power source or a driving device by the lifting action of the upper die 3 after stamping and by the principle of hydraulic power, thereby improving the working efficiency.

It should be noted that the hydraulic oil in the present embodiment may be replaced with air. Similarly, when the connecting rod 5 drives the first piston rod 6 to move outwards of the first chute, vacuum is formed in the cylinder 8, and the second piston rod 7 moves downwards and retracts into the second chute under atmospheric pressure; the connecting rod 5 drives the first piston rod 6 to slide towards the first sliding groove, the first piston rod 6 upwards extrudes air in the sealing cavity, and the second piston rod 7 is jacked up.

In addition, the blanking device for the automobile plates further comprises a positioning laser lamp, and the positioning laser lamp is fixedly arranged on the rack 1. One end of the second piston rod 7 close to the upper die 3 is fixedly connected with a second elastic piece, so that the impact of the second piston rod 7 on the semi-finished plate is reduced. The connecting rod 5 is arched or arc-shaped, so that the connecting rod 5 is prevented from interfering with the lower die 4 in the movement process. An oil filling channel is formed in the lower die 4, an oil filling hole is formed in the cylinder body 8, a bolt is arranged in the oil filling channel and is in threaded connection with the oil filling hole, when too little hydraulic oil exists in the cylinder body 8, the bolt can be unscrewed by using a screwdriver, and then the hydraulic oil is filled into the oil filling channel and the oil filling hole to supplement the hydraulic oil.
