Description

Technical Field

[0001] The invention relates to the technical field of metal cutting and chip breaking, and in particular to a low-consumables and high-pressure chip breaking filtering circulation system and a filtering circulation method thereof. Background Art

[0002] Metal cutting is a material removal and forming method in metal forming process. The tool removes excess metal from the workpiece to be processed, and under the premise of controlling productivity and cost, the workpiece is made to obtain geometric accuracy, dimensional accuracy and surface quality that meet the design and process requirements. To achieve this process, there must be relative movement between the workpiece and the tool, that is, cutting movement, which is provided by the metal cutting machine. In the process of metal cutting, waste chip rings will be generated. If not removed in time, it is easy to cause damage to the workpiece surface and even damage the cutting machine. Therefore, it is necessary to set up a chip breaking system on the cutting machine.

[0003] The patent with publication number CN110653659A discloses an adjustable high-pressure coolant automatic chip breaking device. This solution makes the waste chips bear force on both sides, with a large bending angle, and the chip breaking completely avoids the situation that improper impact aggravates bending and winding, and there will be no unloading of force. The use of two coolants with different water qualities improves the work efficiency, not only strengthens the strength of the coolant that collides with the iron chips, but also avoids the waste of coolant. Combined with the existing technology, the current high-pressure chip breaking system still has the following defects:

[0004] 1) The position of the high-pressure nozzle cannot be adjusted according to the size of the workpiece being processed. In the actual working process, chip breaking failure is prone to occur, the reliability is poor, and the angle of the high-pressure nozzle is not convenient to adjust, resulting in the spray direction of the high-pressure cooling water being easily offset and low accuracy, resulting in unsatisfactory chip breaking effect;

[0005] 2) The high-pressure nozzle generally moves in conjunction with the machine tool cutting tool or drill bit. This method is not convenient for disassembling the chip breaking system. Once the chip breaking system is damaged, it is not easy to repair, which increases the labor intensity of the workers. In addition, the used coolant is not easy to recycle, resulting in a waste of coolant and low practicality. Summary of the invention

[0047] See also Fig.10 The present invention also discloses a low-consumable high-pressure chip breaking and filtering circulation method, which specifically comprises the following steps:

[0048] S1. Injecting coolant: injecting a certain amount of coolant into the collection frame 71 using an external pipe;

[0049] S2, coarse adjustment of chip breaking position: a command is issued through the control panel 12, which is a command to control the motor 43 to start working, including controlling the motor 43 to rotate clockwise or counterclockwise. After receiving the signal, the central processing unit 13 controls the motor 43 to start working, driving the screw rod 44 to rotate, and then driving the first movable block 45 to move, further driving the support plate 61 to move, thereby driving the chip breaking mechanism 6 to move, and adjusting the chip breaking mechanism 6 to a suitable position;

[0050] S3, fine adjustment of chip breaking position: a command is issued through the control panel 12, which is a command to control the hydraulic cylinder 63 to start working, including controlling the hydraulic cylinder 63 to extend or retract. After receiving the signal, the central processing unit 13 controls the hydraulic cylinder 63 to start working, pushing the high-pressure nozzle 1 below to move up and down, adjusting the high-pressure nozzle 1 to a suitable height, and then manually rotating the rotating block 657 to drive the threaded rod 655 to rotate and move up and down relative to the positioning plate 652, and then driving the high-pressure nozzle 1 to rotate through the concave frame 656 and the first fixed sleeve 653, adjusting the liquid outlet angle of the high-pressure nozzle 1, and completing the fine adjustment of the chip breaking position;

[0051] S4, chip breaking: a command is issued through the control panel 12, which is a command to control the high-pressure pump 8 to start working. After receiving the signal, the central processing unit 13 controls the high-pressure pump 8 to start working, extracts the coolant in the collection frame 71 and delivers it to the high-pressure nozzle 1 through the Y-shaped delivery hose 10, and then the coolant is pressurized and sprayed on the waste chip strips produced by the lathe to perform chip breaking;

[0052] S5. Recycling of coolant: the broken waste chips mixed with the used coolant pass through the support plate 61 and fall directly into the collection frame 71 at the bottom. After being filtered by the filter frame 73, the coolant falls under the filter frame 73 and can be recycled. The waste chips are intercepted by the filter frame 73 and retained in the filter frame 73. When it is necessary to clean the waste chips in the filter frame 73, the rotating plate 722 is rotated to drive the limit rod 721 to rotate, so that the rotating plate 722 loses the limit on the filter frame 73, and the filter frame 73 can be pulled out of the collection frame 71 for cleaning.

[0053] In the present invention, the liquid level of the coolant injected in step S1 should be lower than the bottom of the filter frame 73 .

A filtering circulation method of a low-consumables and high-pressure chip-breaking filtering circulation system as claimed in claim 5, characterized in that: The specific steps include: S1, injecting coolant: injecting a certain amount of coolant into the collecting frame (71) using an external pipeline; S2, coarse adjustment of the chip breaking position: a command is issued through the control panel (12), the command being a command for controlling the motor (43) to start working, including controlling the motor (43) to rotate clockwise or counterclockwise. After receiving the signal, the central processing unit (13) controls the motor (43) to start working, driving the screw rod (44) to rotate, thereby driving the first movable block (45) to move, further driving the support plate (61) to move, thereby driving the chip breaking mechanism (6) to move, and adjusting the chip breaking mechanism (6) to a suitable position; S3, fine adjustment of the chip breaking position: a command is issued through the control panel (12), the command is a command to control the hydraulic cylinder (63) to start working, including controlling the hydraulic cylinder (63) to extend or retract, and after receiving the signal, the central processing unit (13) controls the hydraulic cylinder (63) to start working, pushing the high-pressure nozzle (1) below to move up and down, adjusting the high-pressure nozzle (1) to a suitable height, and then manually turning the rotating block (657) to drive the threaded rod (655) to rotate and move up and down relative to the positioning plate (652), and then driving the high-pressure nozzle (1) to rotate through the concave frame (656) and the first fixed sleeve (653), adjusting the liquid outlet angle of the high-pressure nozzle (1), and completing the fine adjustment of the chip breaking position; S4, chip breaking: a command is issued through the control panel (12), which is a command to control the high-pressure pump (8) to start working. After receiving the signal, the central processing unit (13) controls the high-pressure pump (8) to start working, extracts the coolant in the collection frame (71) and delivers it to the high-pressure nozzle (1) through the Y-shaped delivery hose (10), and then the coolant is pressurized and sprayed on the waste chip strip discharged from the machine to perform chip breaking; S5, recycling of coolant: the waste chips after being punched out are mixed with the used coolant and pass through the support plate (61) and directly fall into the collecting frame (71) at the bottom. After being filtered by the filter frame (73), the coolant falls below the filter frame (73) and can be recycled. The waste chips are intercepted by the filter frame (73) and retained in the filter frame (73).

7. The filtering circulation method according to claim 6, characterized in that: The liquid level of the coolant injected in step S1 should be lower than the bottom of the filter frame (73).
