Description

Technical Field

[0001] The utility model belongs to the field of aluminum processing, and particularly relates to a device for blowing aluminum chips from aluminum and aluminum alloy ingots for a milling machine. Background Art

[0002] An aluminum ingot milling machine is a special processing machine used for milling the plane before aluminum ingot rolling. This equipment can realize automatic conveying and automatic flipping of aluminum ingots, and can automatically complete the eight-sided milling processing of various specifications of aluminum ingots. It also has an aluminum chip collection and crushing device, and is a highly automated and efficient aluminum ingot milling processing system.

[0003] The main machine of this milling machine is composed of a gantry, a vertical milling head with a square ram, three side milling heads, a movable workbench, a bed body, a workbench feed, a centering and clamping mechanism, etc. The auxiliary part is composed of an input roller table, a flipping roller table, an output roller table, an aluminum chip collection system, etc.

[0004] During the working process of the aluminum ingot milling machine, it can mill a large plane, two side inclined planes and one side vertical plane at a time. First, the two side milling inclined planes are milled first when milling the ingot, then the large plane, and finally the side vertical plane. When milling the side vertical plane, aluminum chips will splash onto the large plane of the aluminum ingot, and at this time, manual cleaning of the aluminum chips is required.

[0005] The existing cleaning methods are manual wiping or cleaning with a wide mop. The above methods not only increase the labor intensity of workers, but also cause scratches on the ingot surface of the large surface of the aluminum ingot. There are two large surfaces of the slab ingot. After milling one large surface, the movable workbench of the milling machine needs to return to the origin, and it is transported to the ingot flipping machine by the roller table for flipping and swapping the ingot surface to mill the other large surface. The thickness of the aluminum ingot is 630 millimeters, and the minimum thickness of the produced finished product is 0.01 millimeters. Therefore, a very small scratch will be continuously magnified during the subsequent process of processing and rolling. If the scratch is serious, it will cause quality accidents or the raw material will be directly scrapped. Summary of the Invention

[0006] In order to solve the problem that scratches will be left on the aluminum ingot during aluminum chip cleaning, the utility model provides a device for blowing aluminum chips from aluminum and aluminum alloy ingots for a milling machine, which is provided with a gas source, a plurality of air supply pipes, duckbill nozzles and a control module, and uses air flow to complete blowing and cleaning to avoid leaving scratches on the aluminum ingot.

[0007] To achieve the above object, the present utility model provides a device for blowing aluminum chips from aluminum and aluminum alloy ingots used in a milling machine, which includes an aluminum ingot milling machine, a first bracket, and a second bracket. The first bracket is arranged above the aluminum ingot milling machine, and the second bracket is arranged opposite to the aluminum ingot milling machine and is parallel to the aluminum ingot milling machine. There is an aluminum ingot on the aluminum ingot milling machine. The device further includes an air source, a plurality of air supply pipes, a plurality of duckbill nozzles, and a control module. The control module includes a PLC controller, a plurality of relays, and a plurality of solenoid valves. The air source is communicated with the plurality of air supply pipes, and the air supply pipes are connected to the duckbill nozzles through solenoid valves. The solenoid valves are connected to the relays, and the solenoid valves are connected to the power supply through the normally open contacts of the relays.

The probes of the photoelectric switches are perpendicular to the aluminum ingot, the probes of the photoelectric switches are arranged close to the duckbill nozzles, and the photoelectric switches are fixed to the air supply pipes;

[0010] The output ends of the photoelectric switches are connected to the input end of the PLC controller.

[0011] To achieve automatic blowing and cleaning, photoelectric switches are set to detect whether the position of the aluminum ingot is at the position of the duckbill nozzles.

[0012] Further, the detection mechanisms include an infrared laser rangefinder. The infrared laser rangefinder is arranged on the second bracket, the beam emitted by the infrared laser rangefinder acts on the side of the aluminum ingot, and there is an intersection point between the extension line of the output beam of the infrared laser rangefinder and the action point of the photoelectric switch;

[0015] Further, the plurality of air supply pipes are arranged obliquely, and the included angle between the air supply pipes and the space plane is an acute angle.

[0016] The oblique arrangement of the air supply pipes facilitates the airflow to act on the surface of the aluminum ingot.

[0017] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0018] This utility model uses a blowing method to clean aluminum chips. It is provided with an air source, multiple air supply pipes, multiple duckbill nozzles, and a control module.

Detailed Embodiment

[0022] The following further describes this utility model in conjunction with the drawings and detailed embodiments:

[0023] Embodiment 1

[0024] As Figures 1-2 shown, a device for blowing aluminum chips from aluminum and aluminum alloy ingots for a milling machine includes an aluminum ingot milling machine, a first bracket 8, and a second bracket 9. The first bracket 8 is arranged above the aluminum ingot milling machine, the second bracket 9 is arranged opposite to the aluminum ingot milling machine, the second bracket 9 is parallel to the aluminum ingot milling machine, there is an aluminum ingot on the aluminum ingot milling machine, and it further includes an air source, multiple air supply pipes 1, multiple duckbill nozzles 2, and a control module. The control module includes a PLC controller 3, multiple relays 4, and multiple solenoid valves 5. The air source is connected to the multiple air supply pipes 1. The air supply pipe 1 is connected to the duckbill nozzle 2 through the solenoid valve 5. The solenoid valve 5 is connected to the relay 4. The solenoid valve 5 is connected to the power supply through the normally open contact of the relay 4. The coil of the relay 4 is connected to the output end of the PLC controller 3;

[0025] A detection mechanism is arranged on the first bracket 8 and the second bracket 9. The detection mechanism is connected to the PLC controller 3.

[0026] The detection mechanism includes multiple photoelectric switches 6. The probe of the photoelectric switch 6 is perpendicular to the aluminum ingot. The probe of the photoelectric switch 6 is arranged close to the duckbill nozzle 2. The photoelectric switch 6 is fixed to the air supply pipe 1;

[0027] The output end of the photoelectric switch 6 is connected to the input end of the PLC controller 3.

[0028] The detection mechanism includes an infrared laser rangefinder 7, which is arranged on the second bracket 9. The probe direction of the infrared laser rangefinder 7 is parallel to the aluminum ingot milling machine. The light beam emitted by the infrared laser rangefinder 7 acts on the side of the aluminum ingot, and there is an intersection point between the output light beam of the infrared laser rangefinder 7 and the extension line of the action point of the photoelectric switch 6.

[0029] The output end of the infrared laser rangefinder 7 is connected to the input end of the PLC controller 3.

[0030] A plurality of the air supply pipes 1 are arranged equidistantly in a straight line. The air supply pipes 1 are fixedly welded to the first bracket 8. The first bracket 8 is of a circular tubular structure, with a hollow interior. The first bracket 8 is internally communicated with a plurality of the air supply pipes 1.

[0031] A plurality of the air supply pipes 1 are arranged obliquely, and the included angle between the air supply pipes 1 and the space plane is an acute angle.

[0032] The air source provides a pressure of 0.5 Mpa. The PLC controller 3 is a Siemens S7-300. The relay 4 is an RXM2LB2P72 20V12 type relay. The solenoid valve 5 adopts a Best-Mr.0200 solenoid valve 220V12. The photoelectric switch 6 is an E3JK-RR11 photoelectric switch. The infrared laser rangefinder 7 is a DT500-A111 SICK infrared laser rangefinder.

[0033] During operation, the aluminum ingot moves to the position of the photoelectric switch 6 through the aluminum ingot milling machine. Some of the photoelectric switches 6 detect the aluminum ingot. The photoelectric switches 6 that detect the aluminum ingot send electrical signals to the PLC controller 3. At the same time, when the aluminum ingot moves, the infrared laser rangefinder 7 detects the length of the aluminum ingot (the signals output when the aluminum ingot is not detected and when it is detected are different).

The gas in the air source is ejected from the duckbill nozzles 2 through the air supply pipes 1. The gas blows the aluminum chips on the aluminum ingot.

[0036] The photoelectric switches 6 outside the width range of the aluminum ingot cannot detect the aluminum ingot, and the corresponding relay 4, solenoid valve 5, air supply pipe 1 and duckbill nozzle 2 do not work.

[0037] When the infrared laser rangefinder 7 fails to detect the aluminum ingot, the output signal of the infrared laser rangefinder 7 changes. After receiving the output signal of the infrared laser rangefinder 7, the PLC controller 3 controls the coil of the relay 4 to power off, and then the solenoid valve 5 powers off and its valve port closes. The injection work ends.
