Description

Automatic cutting and injection device for decorative strips

Technical field

The invention relates to an oil injection device in the field of automobile parts production research, in particular to an automatic cutting and injection fuel injection device.

Background technique

The automobile outer water cut bright semi-finished product is produced by the rolling process. Before the car is assembled with the outer water of the automobile, the punching machine needs to punch out the notch and carry out the end flanging. The existing operation process is that the operator cuts the semi-finished product from the outer water. The semi-finished product is taken out in the trolley, and the mold is inserted into the mold. Under the pressure of the punching machine, the die is punched out to cut out the shape of the product, and then the end is turned over. The punching and flanging process module is subjected to high force and high surface requirement, resulting in the mold flanging block. Easy to wear, in order to reduce friction, manual injection lubrication is used to improve mold life and reduce mold failure rate. However, at the same time, manual fuel injection will lead to loss of working hours, lowering of the beat, and greater safety risks. The randomness of the fuel injection quantity will also affect the punching quality. If the fuel injection amount is too large, the surface of the product will be dirty, such as the fuel injection amount. Too small, it will not fully lubricate. When the operator performs the punching operation, there is a safety risk by manually punching the fuel injection operation.

As a further improvement of the above technical solution, the mixing valve is provided with a gas pressure regulating nut and a hydraulic pressure adjusting nut.

As a further improvement of the above technical solution, the mounting seat comprises a horizontal seat and a vertical seat fixed at one end of the upper end surface of the horizontal seat, the fuel injection tank is mounted with a lower end surface of the horizontal seat, and the oil pump and the air pump are installed at a level An upper end surface of the seat, at least two mounting grooves are arranged on the vertical seat.

As a further improvement of the above technical solution, the control system is a PLC system.

The invention has the beneficial effects that the invention combines the oil and gas mixture of the mixing valve, and the oil and gas are uniformly mixed by controlling the oil pressure and the air pressure, thereby ensuring that the oil product is sprayed out of the surface of the product in the form of a mist, and the pressure and the fuel injection are controlled by the air pump and the oil pump. Quantity, the mixing valve can manually adjust the gas volume and the amount of oil, while writing the anti-dwelling linkage and injection jet sequence and time in the control system. The operation is very easy, simple, and versatile, and all products produced on the press are applicable.

Detailed ways

The concept, the specific structure and the technical effects of the present invention will be clearly and completely described in conjunction with the embodiments and the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments, based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts belong to The scope of protection of the present invention. In addition, all the coupling/joining relationships mentioned in the text are not directly connected to the components, but rather may constitute a better coupling structure by adding or reducing the coupling accessories according to the specific implementation.

Referring to Figures 1 to 2, An automatic cutting and cutting fuel injection device comprises a mounting seat 2, a mixing valve 3 and an inductor mounted in a punching die, wherein the mounting seat 2 is provided with a control system, a fuel injection tank 1, an oil pump and a gas pump The intake port of the mixing valve 3 is communicated with the air pump through the first pipe, the oil inlet of the mixing valve 3 is communicated with the oil pump through the second pipe, and the oil outlet pipe 4 is disposed on the mixing outlet of the mixing valve 3, The outlet end of the oil delivery pipe 4 projects into the die cutting die, and the control system and the inductor are connected by wires. The mixing valve 3 is provided with a gas pressure adjusting nut and a hydraulic pressure adjusting nut, and the air pressure and the oil pressure are adjusted by the air pressure adjusting nut and the oil pressure adjusting nut, so that the two are mixed to achieve an optimum effect. The mounting base 2 includes a horizontal seat and a vertical seat fixed to one side of the upper end surface of the horizontal seat, the fuel injection tank 1 is mounted with a lower end surface of the horizontal seat, and the oil pump and the air pump are installed on the upper end surface of the horizontal seat. At least two mounting slots 5 are arranged on the vertical seat. The vertical seat is fixed to the side of the punch by the bolt passing through the mounting groove 5. The control system is a PLC system.

The operator starts the punching machine, takes out the semi-finished product of the automobile outside water, removes it from the trolley, inserts it into the mold, touches the in-position sensor in the mold, transmits the stamping signal to the punching machine, presses the punching press to close the mold, and the product is punched in the die. The size required for the product is reached, and the second and third steps are repeated in the above operation, and when the fourth punching process is performed, after the product touches the inductor in the mold, the oil pump starts to start, and the oil pump stores the punch in the can. The oil is pumped out to the mixing valve 3 under the action of air pressure, and the mixing valve 3 mixes the oil and gas according to the demand ratio and ejects. Finally, the punched products are placed in the product, and transferred to another operator for inspection and packaging.

In the above manner, the following effects are achieved:

1. The existing process method relies entirely on manual control operation. Each time the fourth process is punched, manual injection is required. Not only is the labor intensity high, but also the leakage process is easy to occur. After the process transformation, the product is inserted into place. After the automatic injection of oil, the labor intensity of the operator is reduced, and the fuel injection is prevented.

2. The existing fuel injection process is manual injection, and the fuel injection quantity is not easy to control. After the process transformation, the fuel injection can control the oil quantity through the gas volume, the injection time and the injection pressure, and the punching quality is more stable.

3. The existing process is manual injection, and the injection method is dripping, which can not guarantee uniformity. After spraying, it is necessary to manually wipe the residual oil content of the product. After the process modification, the oil and gas can be mixed and sprayed, the oil droplets are fine and uniform, and the product is oil-free. Residue, eliminating the oil rubbing process and improving product production efficiency.
