Detailed ways

The structure of the utility model consists of:

The feeding tray 1 installed on the ground, the feeding conveyor 2 fixed on the middle template 8, the feeding cylinder 3 fixed on the feeding conveyor 2, the push rod 4 fixed on the feeding cylinder 3, The positive and negative detection switch 5 connected to the feeding conveyor 2 and the reverse product receiving chute 7, the positioning cylinder 6 fixed to the middle template 8, the middle mold finger support 10 fixed to the middle template 8, and the The feeding finger 9 and the discharging finger 12 on the middle mold finger bracket 10 are fixedly connected to the female mold 11 on the middle mold plate 8, and the middle mold cylinder 13 fixedly connected to the middle mold finger bracket 10 is fixedly connected to the middle mold plate 8 on the mold detection switch 14.

The action process of the utility model:

Manually put the product into the feeding tray 1, control the rotation of the motor on the feeding tray 1 through PLC, and bring the product to the feeding conveyor 2, and control the rotation of the motor on the feeding conveyor 2 through PLC to drive the product to the positive and negative detection The switch 5 is detected by the positive and negative detection switch 5, and the products in the positive position are pushed to the position positioned by the positioning cylinder 6 by the push rod 4 installed on the feeding cylinder 3, and the products in the reverse position are detected by the positive and negative detection switch 5. The feeding conveyor 2 is collected to the reverse product receiving tank 7. The product positioned by the positioning cylinder 6 clamps the product through the PLC control feeding finger 9. At the same time, the finished product floating on the female mold 11 is clamped through the PLC control discharge finger 12, and the feeding finger 9 is clamped by the middle mold cylinder. Send it to the female mold 11. At this time, when the machine tool is at 360°, the upper slider is at the highest position, the crankshaft clutch is separated, and the upper slider does not move. The middle mold detection switch 14 detects that the feeding finger 9 is placed on the female mold. Products, if the position of the product is correct, the PLC will send a signal to the machine tool, the crankshaft clutch equipped with the upper slider on the machine tool will be sucked in by the PLC, the crankshaft will drive the upper slider to move downward, and the upper slider will drive the upper punch to move downward. The finished product is pressed into the female mold, and driven to punch down on the adjusted down-press adjusting screw, at this time, the upper sliding body is at the lowest position, and it is pressed into shape. With the upward movement of the upper sliding body, the demoulding begins, and the lower punch is driven to reset by the lower punch cylinder and the demoulding pull rod, and the product is taken out of the female mold. If it is detected by the middle mold detection switch 14 that the position of the product placed on the female mold by the feeding finger is incorrect, at the same time the signal is sent to the machine tool through the PLC, the crankshaft clutch is separated, and the touch screen middle mold position fault alarms at the same time, and enters the next step after the manual fault is eliminated. One station. At the same time, the feeding turntable 1 drives the products placed on the turntable to be sent to the positioning cylinder 6 through the feeding conveyor 2 and the feeding cylinder 3 for positioning, then clamped by the feeding finger 9 and sent to the female mold 11 through the middle mold cylinder 13. At 360°, the upper sliding body is at the highest position, and the upper and lower die punches are driven by the mechanism to enter a new round of pressing, which goes round and round.
