Description

Technical Field

[0001] This invention relates to the field of welding machine heat dissipation technology, specifically a friction welding machine heat dissipation cooler. Background Art

[0002] Friction welding machines are devices that generate heat energy during rotation and then apply appropriate pressure to complete the welding process. Based on the energy input method, friction welding machines are divided into two types: continuous drive and inertial drive. The former consists of a clamp, transmission mechanism, pressurizing mechanism, braking device, and control device; the latter consists of a clamp, transmission mechanism, flywheel, pressurizing mechanism, and control device.

[0003] Friction welding machines rely on the high heat generated by friction to melt and reassemble the weldment, thus achieving welding. This requires a relatively high temperature. Once the welding temperature is reached, the welding is considered complete and needs to be cooled. Traditionally, this is done by natural cooling or air drying. These methods are cumbersome, and prolonged exposure can affect the integrity of the weldment. Furthermore, manual cooling is inefficient and cannot be performed immediately after welding. Summary of the Invention

[0004] This invention provides a heat dissipation cooler for a friction welding machine, which solves the problems mentioned in the background art.

[0005] To achieve the above object, the present invention provides the following technical solutions: A friction welding machine heat dissipation cooler includes a welding machine housing and further includes: Mounting legs are installed at the bottom of the welding machine housing, and a mounting shell is installed on one side of the welding machine housing. A cooling mechanism is installed on the mounting shell, including multiple induction cylinders fixedly installed through the mounting shell. A piston column is slidably installed through the top wall of the induction cylinder. A sealing block is fixedly connected to one end of the piston column and is slidably installed inside the induction cylinder. A mounting head is fixedly connected to the top of the piston column. Transmission rods are hinged to both sides of the mounting head. Gas transmission pipes are fixedly connected to the mounting shells on both sides of the induction cylinders. A limiting cylinder is fixedly connected to one side of the gas transmission pipe. A valve assembly is installed inside the limiting cylinder. A limiting component is installed on the inner wall of the limiting cylinder. Cooling heads and heat dissipation heads are respectively installed on both sides of the induction cylinders inside the mounting shell. The cooling cylinders and heat dissipation heads are fixedly connected to the gas transmission pipes. A sensing component is installed on the gas transmission pipe on one side of the heat dissipation head. A temperature sensing component is installed inside the heat dissipation head. A cooling component is installed at the bottom of the welding machine housing. A telescopic pipe is installed between the cooling component and the gas transmission pipe. The valve assembly improves welding efficiency while accurately dissipating heat according to the welding temperature inside the mounting shell.

[0006] As a preferred embodiment of the present invention, the valve assembly includes a closing plate slidably disposed within a limiting cylinder, a valve rod fixedly connected to one side of the closing plate, a valve port being opened on the valve rod, one end of the valve rod passing through an air transmission pipe, and the end being hingedly connected to a transmission rod.

[0007] As a preferred embodiment of the present invention, the limiting component includes protrusions fixedly disposed on both sides of the inner wall of the limiting cylinder, a telescopic cylinder fixedly connected to the valve stem sidewall on one side of the protrusions, an arc-shaped block fixedly disposed at the end of the telescopic cylinder, and a reset component sleeved on one end of the telescopic cylinder.

[0008] As a preferred embodiment of the present invention, the sensing component includes a piston block slidably disposed in the air transmission tube, a detection column fixedly connected to the top of the piston block, one end of the detection column slidably penetrating the top wall of the air transmission tube, a limiting block fixedly connected to the top of the detection column, and an elastic element sleeved on one end of the detection column.

[0009] As a preferred embodiment of the present invention, the temperature sensing component includes a sealing plate that is slidably disposed on both sides of the heat sink head, a positioning block is fixedly connected to the top of the sealing plate, and a thermal expansion member is fixedly connected between the positioning blocks.

[0010] As a preferred embodiment of the present invention, the cooling assembly includes a radiator and a cooler fixedly installed on both sides of the bottom of the welding machine box. The air inlet end of the radiator and the air outlet end of the cooler are both fixedly connected to air guide pipes. The air guide pipes are fixedly connected to telescopic pipes. The telescopic pipe on one side of the probe column is fixedly connected to the air guide pipe on one side of the radiator.

[0011] As a preferred embodiment of the present invention, a friction welding machine is installed inside the welding machine housing, and a mounting block is fixedly connected to the side wall of the welding machine housing on one side of the friction welding machine, with the mounting block and the mounting shell being rotatably connected.

[0012] This invention has the following advantages: In actual use, the workpiece to be welded is placed in the friction welding chamber, and then welding is performed. The mounting shell is then manually rotated to contact the welding machine housing to achieve a seal. As the welding process continues, the temperature inside the mounting shell rises. When the temperature reaches its maximum, it indicates that the weld is complete. At this point, due to the accumulation of hot air inside the mounting shell, the internal pressure increases, which in turn causes the sealing block to move upwards. The sealing block then causes the mounting head above the piston column to move upwards. At this point, the operator can turn off the welding machine, preventing further heat generation. Under the action of the transmission rod, the mounting head moves the valve stem, and the valve port on the valve stem moves. Connected to the air transmission pipe, the cooler and radiator cool the welding position of the welded parts through the cooling head and heat dissipation head, respectively. As the temperature gradually decreases, the thermal expansion component in the heat dissipation head expands and contracts, driving the sealing plate to move laterally through the positioning block. When the temperature reaches the standard temperature, the sealing plate seals the heat dissipation head. At this time, a negative pressure is generated in the air transmission pipe, and the probe column below the limit block moves down, indicating that the heat dissipation is complete. Only then can the next round of welding operations be carried out. This welding method can efficiently realize the heat dissipation and cooling process in the welding operation, improve welding efficiency, and significantly improve welding quality. At the same time, it can automatically adjust the welding cooling process and is easy to operate. Attached Figure Description

At this time, a negative pressure is generated in the air transmission pipe 12. The detection column 29 below the limit block 17 moves downward, indicating that the heat dissipation is complete. In this case, the operator can change the welding part. Example 2

The reset component 26 can be a spring or an elastic metal sheet with telescopic properties.

[0031] The sensing component 36 includes a piston block 28 slidably disposed in the air transmission tube 12, a detection column 29 fixedly connected to the top of the piston block 28, one end of the detection column 29 slidably penetrating the top wall of the air transmission tube 12, a limiting block 17 fixedly connected to the top of the detection column 29, and an elastic element 16 sleeved on one end of the detection column 29.
