The electrical appliance part comprises an electrical junction box, an I/O module, a sensor, an air cylinder, a valve island, circuit butt joint and air path quick plug. And connecting the electric circuits in different forms according to different standards of customer sites. The electrical butt joint is the butt joint of a die side electrical part and a press side electrical part, a common form is the matching butt joint of a male plug and a female plug of an aviation plug, the press side plug provides a power supply as a female head, and the die side plug receives the power supply as a male head; the power supply and the signal transmission can be realized by induction butt joint without contact and corresponding positions of a pair of couplers, which are not common and use passive couplers. The sensors are mainly used for detecting the in-place of the workpiece, the number of the sensors of the jacking mechanism is 4 generally, the number of the sensors of the jacking mechanism is 2, the number of the sensors of the tire membrane is 2, the sensors are generally arranged diagonally so as to avoid damage to a press and a mold caused by inclination of the workpiece, and a 3-wire PNP type M12 connector type is generally selected and matched with an M12 prefabricated cable to transmit sensor signals to the press; the sensors of the conveying mechanism are generally arranged on a belt conveyor, and 2 sensors are respectively arranged on a feeding belt conveyor, a profile inner belt conveyor and a discharging belt conveyor, but because the workpiece is special in shape, the inductive sensors cannot normally realize the logic control of feeding and discharging detection, so the feeding and discharging detection sensors are mostly selected from photoelectric sensors, when the workpiece passes through, the light emitted by the photoelectric sensors is blocked, the workpiece cannot receive a reflection signal, namely the workpiece is considered to be a workpiece, and until the workpiece passes through, the photoelectric sensors receive the reflection signal, namely the workpiece is considered to be completely passed through, so that only one workpiece is arranged in a die when the press is pressed at each time. There are generally 2 ways in which the sensor signals are transmitted to the press, one being an I/O module and the other being an electrical junction box. The I/O module typically takes the form of a communication link, with the sensor being connected to the input point of the I/O module by a pre-formed cable, and the sensor signal being transmitted to the press via the communication link of the I/O module. The electric junction box adopts a mode that the signal points correspond to wiring, the signals of the sensor are connected into the terminals in the junction box, and the wires connected out of the terminals are connected to the corresponding pins of the circuit butt plug so as to finish the corresponding connection of the sensor and the press. Except for a few old-fashioned presses, the mould jacking mechanism, the front baffle mechanism and the overturning required by most of the existing presses are provided with air cylinders, different series of air cylinders are selected to complete corresponding functions according to the size and the function of each mechanism, and the cylinder diameter and the air cylinder stroke are generally given after the mould design and the site communication are confirmed. The cylinder action is controlled by a valve plate, and a two-position five-way valve and a manual electromagnetic dual-control type are common. If the sensor adopts an I/O module to transmit signals, the valve island is selected for cylinder action control, the valve island and the valve island adopt the same communication protocol, and the valve island are connected with the press through a communication prefabricated cable. If the sensor adopts the electric junction box to transmit signals in a terminal wiring mode, the common valve plate is selected for cylinder action control, and the control line of the electromagnetic valve is also connected to the corresponding terminal in the electric junction box, so that the press can control the cylinder action. The speed of the cylinder action is controlled by a speed regulating valve, and each branch gas circuit is provided with a speed regulating valve to regulate the speed of the cylinder switch action so as to enable the cylinder switch action to reach an ideal state. The air supply of mould side gas circuit is that the press side provides, connects through the quick connector of gas circuit, and the press side is for inserting female head of self-locking-type gas circuit soon, can not leak gas when not connecting, and the mould side is for inserting the public head of gas circuit soon that corresponds.

Generally, a plurality of sets of dies are used on the same press on site, so that electrical parts of the dies on the same press need to be interchangeable, and the brands and the models are kept consistent as much as possible, so that later maintenance is facilitated. Meanwhile, the press has a code identification function for each die, and the die codes in the press can be identified by butting the die with the press circuit, so that the loss caused by wrong dies on a workpiece is prevented.

As shown in figure 1, the equipment is an automatic feeding and discharging type conveying mechanism and is arranged at the position of a lower tire mold of a stamping die for use. The jacking mechanism and the front material blocking mechanism 6 are lifted in the initial condition, workers place belt-covered parts on a belt conveyor which is self-matched in a factory, and after the parts are placed, the parts are conveyed by pressing a starting switch. After the parts are conveyed to the designated position of the jacking mechanism through the feeding belt mechanism 1, the parts impact a collision rod 36 of the front material blocking mechanism 6, the other end of the collision rod 36 blocks a sensor, the sensor detects the presence of materials, and the belt conveyor stops conveying; the front stock stop 6 descends, the lifting mechanism descends, and the part falls into the tire membrane. After the parts are blanked in place, the sensor sends a signal, the press descends and closes the die, the top end of the spring type side blocking upright post is pressed down, and the parts are covered with edges. After the edge covering is finished, the press is lifted upwards, the lifting mechanism is lifted to the position after the press is lifted, the sensor is lifted to the position to detect the workpiece, the lifting belt conveyor and the discharging belt conveyor start to convey, and the workpiece is discharged from a die. The parts are conveyed to a factory self-matched discharging mechanism through a lifting mechanism belt conveyor and a discharging belt conveyor, the presence of materials is detected, and the whole process is completed.
