[0035] In order to better explain the present invention and facilitate understanding, the technical scheme and effects of the present invention are described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0036] like Figures 1 to 7 As shown, this embodiment provides a light alloy profile extrusion sawing device, including a sawing device, a rail assembly 1 fixedly arranged on the ground, a walking drag chain assembly 2 arranged on the ground side by side with the rail assembly 1, and an air circuit assembly 3 arranged between the rail assembly 1 and the walking drag chain assembly 2; the sawing device is slidably installed on the rail assembly 1, and the sawing device can be supported by setting the rail assembly 1, and the sawing device can be longitudinally moved on the rail assembly 1; the walking drag chain assembly 2 is connected to the sawing device, and is equipped with a cable and an air pipe for traction and protection of the sawing device, and the air circuit assembly 3 is connected to the sawing device to provide a clean and stable air source for the device.

[0037] like Figures 2 to 3 As shown, the sawing device includes a frame assembly 4, a feeding assembly, a servo reducer drive assembly 5, a boat pressing assembly 6, a feeding reducer assembly 8, a chip dust collection assembly 11 and a feeding drag chain assembly 12.

[0038] Specifically, wheel sets matching the rail assembly 1 are provided on both sides of the frame assembly 4, and the wheel sets drive the sawing device carried by them to move along the rail assembly 1; a support frame is fixedly installed above the two wheel sets, which plays the role of carrying various components of the sawing device; the servo reducer drive assembly 5 is arranged on the side ridges of the support frame in the running direction of the frame assembly 4, and is connected with the wheel set of the frame assembly 4, and drives the entire sawing device to reciprocate on the rail assembly 1 through a gear rack transmission, thereby providing source power for the sawing device;

[0039] The ship-holding assembly 6 is arranged on a support frame above one side wheel group, including a lifting track arranged at one end of the support frame and a ship-holding member slidably connected to the lifting track. The ship-holding member is driven by a hydraulic cylinder to vertically lift and lower along the lifting track to adjust the lifting height for profiles of different sizes. Due to the different sizes of light alloy profiles, the heights of the lead-out rollers 13 of different light alloy profiles are also different, and the extended lengths of the hydraulic cylinders are also different. During sawing, the ship-holding assembly 6 can be vertically lifted and lowered on the sawing device and press down the rollers 131 of the corresponding lead-out rollers 13, so that the sawing device will not scrape against the rollers 131 of the lead-out rollers 13 when it reciprocates on the rail assembly 1.

[0040] like Figure 4 As shown, the feed assembly includes a sawing moving frame 7 arranged on the support frame of the frame assembly 4, and a saw head assembly 9 and a micro-lubrication assembly 10 installed on the sawing moving frame 7; the sawing moving frame 7 is used to carry the saw head assembly 9 and the micro-lubrication assembly 10. The saw head assembly 9 includes a saw blade with a protective cover, the rotating shaft passes through the center of the protective cover, and is connected to the motor through a belt. The motor drives the saw blade through the belt to interrupt the continuous extrusion of the light alloy profile. The lower end of the saw blade is provided with a chip collecting groove. The micro-lubrication assembly 10 is arranged on one side of the motor. By connecting the oil pipe on the micro-lubrication assembly 10 to the saw blade protective cover, a nozzle is installed at the end of the oil pipe so that the sprayed oil is in a mist form, so as to better cool and lubricate the saw blade during sawing.

[0041] like Figure 3 As shown, the feed reducer assembly 8 is arranged on the support frame of the frame assembly 4, and is mechanically connected to the bottom of the feed assembly to provide source power for the reciprocating motion of the feed assembly.

[0042] like Figure 5 and Figure 6 As shown, in this embodiment, the chip dust collection assembly 11 is arranged on a support frame close to the side of the saw head assembly 9, and includes a cyclone separator 15, a secondary dust collector 16 and an explosion-proof centrifugal fan 14. The cyclone separator 15 is connected to the secondary dust collector 16 through the explosion-proof centrifugal fan 14, and the explosion-proof centrifugal fan 14 transports the gas separated by the cyclone separator 15 to the secondary dust collector 16 for further purification.

[0043] The cyclone separator 15 includes an explosion relief valve 17 separately arranged on the side plate of the cyclone separator 15, a pressure differential transmitter 21 arranged on the other side plate, and an air duct 20; when the temperature in the cyclone separator 15 is too high or an abnormality occurs, the explosion relief valve 17 can quickly isolate and release the heat of the cyclone separator 15 without causing damage to other components, effectively avoiding the deterioration of the abnormal situation and ensuring the safety of the production workshop and equipment; a chip collecting box 19 with a built-in filter is provided at the bottom of the cyclone separator 15; the chip collecting box 19 has an explosion-proof type with a thermal resistor temperature The sensor 18 can measure the temperature of the chip collecting box 19. When the temperature is too high, that is, exceeds the set maximum temperature, the flameproof temperature sensor 18 with thermal resistance will give an alarm, and the staff can clean the chips through the chip discharge channel at the bottom of the chip collecting box 19 in time to prevent the chips from spontaneously igniting. The differential pressure transmitter 21 can monitor the pressure difference between the two cavities above and below the filter. The filter is prone to blockage when collecting chips. When the pressure difference between the two cavities exceeds the set pressure difference, the pressure transmitter 21 will send a signal, and the staff can know in time that the filter is blocked and needs to be cleaned.

[0044] In addition, an air bag assembly 22 is provided above the differential pressure transmitter 21. The air bag assembly 22 includes an air bag body and a pressure gauge installed on the air bag body for measuring and displaying pressure values. The air bag body is connected to the cyclone separator 15 through multiple sets of pipelines. A pulse valve is provided on the pipeline. The air bag body stores gas. When there are chips on the filter screen, the filter screen can be cleaned at irregular intervals through the control of the pulse valve on the air bag assembly 22 to ensure the ventilation volume.

[0045] In this example, the lower end of the air duct 20 is connected to the chip collecting groove at the lower part of the saw head assembly 9 of the feed assembly, so that the chips cut by the saw blade are sucked into the cyclone separator 15.

[0046] The air circuit assembly 3 in this embodiment provides an air source for the minimal lubrication assembly 10 and the air bag assembly 22 .

[0047] like Figure 3 As shown, the feed chain assembly 12 is arranged side by side with the feed assembly on the support frame of the frame assembly 4, the moving end of the feed chain assembly 12 is connected to the sawing moving frame 7 on the feed assembly, and the fixed end is connected to the frame assembly 4, the feed chain assembly 12 has built-in cables and air pipes, when the feed reducer assembly 8 drives the feed assembly to move horizontally, the saw head assembly 9, the electrical and gas equipment of the minimal lubrication assembly 10, and the cables and air pipes also need to move accordingly, and the feed chain assembly 12 needs to be protected on the equipment, so as to provide traction and protection for the feed assembly.

[0048] A working process of the utility model:

[0049] The light alloy material is extruded by an extruder to form a light alloy profile. The light alloy profile that has not been cooled by a quenching device is transported out by a lead-out roller 13. The lead-out roller 13 is arranged side by side with the rail assembly 1. At this time, the light alloy profile is in a high temperature state. When the profile material seam reaches this device, the servo reducer drive assembly 5 is started to drive the sawing device to move quickly on the rail assembly 1. During the process of driving the sawing device to move quickly, the ship pressing assembly 6 on the sawing device presses down and tilts the roller 131 of the lead-out roller 13 through which the sawing device passes under the action of the hydraulic cylinder to avoid collision between the sawing device and the roller 131 of the lead-out roller 13. When the speed of the sawing device reaches synchronization with the extrusion speed of the light alloy profile, At this moment, the sawing device and the position of the profile seam are relatively still. The feed assembly starts to move horizontally through the power drive of the feed reducer assembly 8 and the meshing drive of the spur gear rack, so that the saw head assembly 9 extends to saw off the extruded continuous light alloy profile near the joint; when the saw head assembly 9 is sawing, the minimal lubrication assembly 10 starts to work to cool and lubricate the saw blade of the saw head assembly 9. When sawing, the air duct 20 of the chip dust collection assembly 11 sucks the chips cut by the saw blade into the cyclone separator 15. The cyclone separator 15 separates the chip solids into the chip collection box 19, and the separated gas is transported to the secondary dust collector 16 through the explosion-proof centrifugal fan 14 for purification again.

[0050] The micro-lubrication assembly 10 needs to be regularly added with cooling lubricating oil, and the saw blade needs to be sharpened after sawing for a period of time, otherwise the cutting quality and the service life of the saw blade will be affected.
