Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner two-component production equipment, specifically to a punch press oil supply device for air conditioner two-component production. Background Technology

[0002] In the manufacturing of air conditioning components, punch presses are one of the key pieces of equipment used to process air conditioning components. During the production and processing of air conditioning components by punch presses, the punch press dies need to be continuously and quantitatively supplied with oil to ensure the normal operation and processing accuracy of the dies and extend the service life of the dies.

[0003] Currently, existing punch press oil supply devices typically use pneumatic pumps for oil supply. However, in actual production, due to the high operating frequency of punch presses, pneumatic pumps need to operate frequently to meet the demand for continuous and quantitative oil supply to the mold. This high-frequency operating state leads to accelerated wear of the internal components of the pneumatic pump, which in turn makes the pneumatic pump prone to failure and requires frequent repair or replacement. This not only affects production efficiency and increases maintenance costs, but also affects the processing quality of the mold due to untimely oil supply. Utility Model Content

[0004] The purpose of this utility model is to provide a punch press oil supply device for the production of two air conditioning components, so as to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An oil supply device for a punch press used in the production of two air conditioning components includes a left oil tank and a right oil tank. Two solenoid valves are provided between the left and right oil tanks. The left and right ports of the two solenoid valves are respectively connected to the interior of the left and right oil tanks through pipes. The two solenoid valves are closed when the left oil tank is being filled. The top of the left oil tank is provided with an exhaust port and an oil filling port. The top of the right oil tank is provided with an oil outlet and a straight air inlet. Two connecting parts connected to the interior are provided on the left side of the left oil tank. Air pipe connectors are threaded to the outer side of the two connecting parts. An air pipe body is provided between the two air pipe connectors. Two liquid level detection switches are tied to the outer side of the air pipe body.

[0007] The beneficial effects of this utility model are as follows: the continuous oil supply is ensured by the cooperation of two oil tanks. When the oil level in the left oil tank is lower than the liquid level detection switch below, the two connecting solenoid valves are closed, and the left oil tank simultaneously performs the venting and refilling operations. After the left oil tank is full, the two connecting solenoid valves are opened again, and the oil flows from the left oil tank to the right oil tank by gravity to maintain a continuous oil supply at the outlet. During the refilling of the left oil tank, the right oil tank independently maintains the oil supply operation, thereby achieving the effect of continuous operation during the oil supply process.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, a tee pipe is threaded onto the outer side of the exhaust port.

[0010] The beneficial effect of adopting the above-mentioned further solution is that it divides the originally single exhaust path into two paths, which are connected to different functional components respectively, thereby improving the stability of the entire device during use.

[0011] Furthermore, a manual venting ball valve is threadedly connected to the left side of the three-way pipe, an automatic venting solenoid valve is threadedly connected to the right side of the three-way pipe, and a refueling solenoid valve is threadedly connected to the outer side of the refueling port.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by using both manual and automatic venting methods, air resistance can be avoided during the refueling process of the left oil tank, thereby reducing the refueling speed.

[0013] Furthermore, the oil outlet directly supplies oil to the mold through the oil outlet pipe.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the right oil tank can directly supply oil to the mold through the oil outlet pipe connected to the oil outlet, which is more convenient.

[0015] Furthermore, both the bottom of the left and right oil tanks are connected to cleaning ball valves.

[0016] The beneficial effect of adopting the above-mentioned further solution is that when it is necessary to clean the left and right oil tanks, the waste liquid generated during the cleaning process can be discharged through the cleaning ball valve. Attached Figure Description

Detailed Implementation

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1, as Figures 1-3 As shown, a punch press oil supply device for the production of two air conditioning components includes a left oil tank 1 and a right oil tank 2. Two solenoid valves 3 are provided between the left oil tank 1 and the right oil tank 2. The left and right ports of the two solenoid valves 3 are respectively connected to the interior of the left oil tank 1 and the right oil tank 2 through pipes. The two solenoid valves 3 are closed when the left oil tank 1 is filled with oil. The top of the left oil tank 1 is provided with an exhaust port 4 and an oil filling port 5. The top of the right oil tank 2 is provided with an oil outlet 6 and a straight air inlet 7. The left side of the left oil tank 1 is provided with two connecting parts 15 that are connected to the interior. The outer side of each of the two connecting parts 15 is threaded with an air pipe connector 16. An air pipe body 17 is provided between the two air pipe connectors 16. Two liquid level detection switches 8 are tied to the outer side of the air pipe body 17.

[0024] When the lower liquid level detection switch 8 detects that the oil level in the left oil tank 1 has dropped below the lower liquid level detection switch 8, it transmits a signal to the control terminal (this is the operation set in the mold quantitative oil supply device, so it will not be described in detail). This controls the two connected solenoid valves 3 to close. At this time, oil is injected into the left oil tank 1 through the filling port 5, and the gas in the left oil tank 1 is discharged through the exhaust port 4 to ensure stability during the filling process. When the upper liquid level detection switch 8 detects that the oil level has reached the upper position, it transmits a signal to stop the filling and open the two connected solenoid valves 3. Thus, the oil in the left oil tank 1 flows into the right oil tank 2 under the action of the pipeline and the two connected solenoid valves 3, replenishing the oil in the right oil tank 2 and ensuring the stability of the right oil tank 2 in the process of supplying oil to the mold. The machine can be shut down during the replenishment process. The air inlet 7 is for compressed air, and the oil is forced out of the right oil tank 2 by the pressure of the compressed air.

[0025] Example 2 is a further improvement based on Example 1, and its specific details are as follows: A three-way pipe 9 is threadedly connected to the outer side of the exhaust port 4.

[0026] With this setup, auxiliary equipment can be connected via the three-way pipe 9, ensuring that the exhaust port 4 can stably exhaust air during use.

[0027] Example 3 is a further improvement based on Example 1, and it is as follows: The left side of the three-way pipe 9 is threaded with a manual exhaust ball valve 10, the right side of the three-way pipe 9 is threaded with an automatic exhaust solenoid valve 11, and the outer side of the oil filling port 5 is threaded with an oil filling solenoid valve 12.

[0028] With this configuration, the vent 4 is controlled by either a manual vent ball valve 10 or an automatic vent solenoid valve 11. This avoids damage caused by a single control valve, which could prevent venting and affect the refueling process. Therefore, a manual vent ball valve 10 or an automatic vent solenoid valve 11 is used for control. If one valve fails, the other valve can be used to vent the vent. The refueling solenoid valve 12 controls the flow of oil into the left oil tank 1.

[0029] Example 4 is a further improvement based on Example 1. Specifically, the oil outlet 6 directly supplies oil to the mold through the oil outlet pipe, which is not shown in the figure.

[0030] This setup allows for direct connection between the mold's oil supply pipe and the oil outlet 6, enabling direct oil supply.

[0031] Example 5 is a further improvement based on Example 1, and its specific details are as follows: The bottom of both the left oil tank 1 and the right oil tank 2 are connected to a cleaning ball valve 14.

[0032] With this configuration, the cleaning ball valve 14 can prevent oil leakage from the oil tank when it is closed, and the waste liquid can be discharged by opening the cleaning ball valve 14 when cleaning the oil tank.

[0033] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
