[0002]制罐的组合机是将罐身和罐盖进行冲压组合的设备,组合机在环形区域内涉及多个冲压组合单元,冲压组合机构的润滑油统一供给,由于冲压组合机构持续作业致使润滑油温度升高,在超出45摄氏度后将影响传动运行的可靠性和机构传动件的使用寿命,目前,以自然散热的方式为主,将润滑油输入管道连接散热管,这种降温方式在冬季基本可以维持运行温度,但是在夏季,润滑油温度持续运行情况下高达60摄氏度左右
[0007]Based on the requirements, this solution allows for two options: either cold water can be directly introduced into the cooling medium inlet pipe, or cold water can first enter the water tank, then cool the oil pump in the tank before entering the cooling medium inlet pipe. When the cold water source is directly connected to the cooling medium inlet pipe, the cold water cools the lubricating oil within the plate heat exchanger. The lubricating oil, after being discharged from the lubricating oil outlet pipe of the combined unit, enters the plate heat exchanger. The cooled lubricating oil then passes through the oil pump and enters the combined unit from the lubricating oil inlet pipe. In this method, the lubricating oil entering the combined unit is cooled only by the plate heat exchanger. In summer, the cold water source can be first connected to the water tank, where the oil pump is cooled before entering the plate heat exchanger. In this way, the lubricating oil cooled by the plate heat exchanger can be further water-cooled within the water tank, ensuring that the lubricating oil entering the combined unit is close to the temperature of the cold water source, resulting in stronger temperature control.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of can-making equipment technology, and in particular to a lubricating oil supply system for a combined machine. Background Technology
[0002] The can-making assembly machine is a device that stamps and assembles the can body and can lid. The assembly machine involves multiple stamping assembly units within a circular area. The lubricating oil for the stamping assembly mechanism is supplied uniformly. Due to the continuous operation of the stamping assembly mechanism, the temperature of the lubricating oil rises. When it exceeds 45 degrees Celsius, it will affect the reliability of the transmission operation and the service life of the transmission components. Currently, natural heat dissipation is the main method, with the lubricating oil input pipe connected to the heat dissipation pipe. This cooling method can basically maintain the operating temperature in winter, but in summer, the lubricating oil temperature can reach about 60 degrees Celsius under continuous operation. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention proposes a method for effectively cooling the lubricating oil in combined machines.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a lubricating oil supply system for a combined machine, the combined machine including a lubricating oil inlet pipe and a lubricating oil outlet pipe, characterized in that the lubricating oil supply system includes a plate heat exchanger, a water tank and an oil pump, the plate heat exchanger including a hot medium inlet pipe, a hot medium outlet pipe, a cold medium inlet pipe and a cold medium outlet pipe, the inlet of the water tank being connected to a water source, the outlet of the water tank being connected to the cold medium inlet pipe, the cold medium outlet pipe being connected to a drain pipe, the hot medium inlet pipe being connected to the lubricating oil outlet pipe, the hot medium outlet pipe being connected to the inlet of the oil pump, and the lubricating oil inlet pipe being connected to the outlet of the oil pump.
[0005] Furthermore, the oil pump is located below the liquid level in the water tank.
[0006] Furthermore, a bypass pipe is connected between the cold medium inlet pipe and the water source, and a valve is respectively installed on the bypass pipe and the outlet pipe of the water tank.
[0007] Based on the requirements, this solution allows for two options: either cold water can be directly introduced into the cooling medium inlet pipe, or cold water can first enter the water tank, then cool the oil pump in the tank before entering the cooling medium inlet pipe. When the cold water source is directly connected to the cooling medium inlet pipe, the cold water cools the lubricating oil within the plate heat exchanger. The lubricating oil, after being discharged from the lubricating oil outlet pipe of the combined unit, enters the plate heat exchanger. The cooled lubricating oil then passes through the oil pump and enters the combined unit from the lubricating oil inlet pipe. In this method, the lubricating oil entering the combined unit is cooled only by the plate heat exchanger. In summer, the cold water source can be first connected to the water tank, where the oil pump is cooled before entering the plate heat exchanger. In this way, the lubricating oil cooled by the plate heat exchanger can be further water-cooled within the water tank, ensuring that the lubricating oil entering the combined unit is close to the temperature of the cold water source, resulting in stronger temperature control.

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0011] like Figure 1 As shown, the combined machine includes a lubricating oil inlet pipe and a lubricating oil outlet pipe. The lubricating oil supply system includes a plate heat exchanger 1, a water tank 2, and an oil pump 3. The plate heat exchanger 1 includes a hot medium inlet pipe 11, a hot medium outlet pipe 12, a cold medium inlet pipe 13, and a cold medium outlet pipe 14. The inlet of the water tank 2 is connected to a water source, the outlet of the water tank 2 is connected to the cold medium inlet pipe 13, the cold medium outlet pipe 14 is connected to a drain pipe, the hot medium inlet pipe 11 is connected to the lubricating oil outlet pipe, the hot medium outlet pipe 12 is connected to the inlet of the oil pump 3, and the lubricating oil inlet pipe is connected to the outlet of the oil pump 3.
[0012] The oil pump 3 is located below the liquid level in the water tank 2. A bypass pipe 4 is connected between the cold medium inlet pipe 13 and the water source. A valve is installed on the bypass pipe 4 and the outlet pipe of the water tank 2.
[0013] Based on the requirements, this solution can be configured to allow cold water to directly enter the cold medium inlet pipe 13, or to allow cold water to first enter the water tank 2, then cool the oil pump 3 in the water tank 2 before entering the cold medium inlet pipe 13. When the cold water source is directly connected to the cold medium inlet pipe 13, the cold water cools the lubricating oil in the plate heat exchanger 1. The lubricating oil, after being discharged from the lubricating oil outlet pipe of the combined machine, enters the plate heat exchanger 1. The cooled lubricating oil then passes through the oil pump 3 and enters the combined machine from the lubricating oil inlet pipe. In this method of lubricating oil cooling, the lubricating oil entering the combined machine is only cooled by the plate heat exchanger 1. In summer, the cold water source can be first connected to the water tank 2, where the oil pump 3 is cooled before entering the plate heat exchanger 1. In this way, the lubricating oil cooled by the plate heat exchanger 1 can be further water-cooled in the water tank 2, thus ensuring that the lubricating oil entering the combined machine is close to the temperature of the cold water source, resulting in stronger temperature control.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
