Description

Technical Field

[0001] The utility model relates to the technical field of cutting fluid recovery, in particular to a cutting fluid recovery device for metal cutting processing. Background Art

[0002] Metal cutting is a process that uses cutting tools to process metal parts into specified shapes and sizes. In order to ensure the temperature of the cutting tools and parts and the cutting effect, cutting fluid is usually sprayed during cutting. The used cutting fluid can be recycled by centrifugally separating the waste chips.

[0003] At present, the patent with announcement number CN204339455U discloses a cutting fluid recovery device, including a shell, a liquid outlet pipe is provided in the shell, a centrifugal roller is pivoted in the shell, the side of the centrifugal roller is a sieve-like dense hole, one end of the centrifugal roller is connected to the rotating shaft, the rotating shaft is connected to the motor, the other end of the centrifugal roller is connected to the main pipe through a sealing ring, the main pipe is connected to the feed pipe and the outlet pipe in a branched manner, and a backwash water pipe is also provided in the shell, and the backwash water pipe is provided with a water spray head aimed at the centrifugal roller. Cutting fluid with metal fragments is sprayed into the centrifugal drum under pressure, the motor drives the rotating shaft to rotate, the rotating shaft drives the centrifugal drum to rotate, the centrifugal force generated by the rotation throws the cutting fluid out from the sieve-like dense holes on the side of the centrifugal roller, the cutting fluid enters the shell cavity, and flows out through the liquid outlet pipe, and the metal fragments in the centrifugal roller flow to the outlet under the impact of the water spray head. The feed pipe and the outlet pipe enter the centrifugal roller from the same main pipe, with a simple structure and easy operation. The cutting fluid is separated by centrifugation, which greatly improves the separation rate. The design of the recoil water pipe spray head promotes the rapid sliding of metal fragments. The device has low cost, good recovery quality and high efficiency.

[0004] However, the current cutting fluid recovery device still has the following problems during use:

[0005] When in use, the above-mentioned device separates the cutting fluid and waste chips by rotation through centrifugation. However, when processing workpieces made of materials such as iron, the cutting waste chips are small and thus difficult to be filtered by the holes provided on the centrifugal barrel. That is, the small waste chips will flow out with the cutting fluid. At this time, as the number of cycles increases, the amount of fine waste chips contained in the cutting fluid increases, which will affect the normal use of the cutting fluid and block the cutting fluid delivery pipeline. Utility Model Content

Through the above structure, it is convenient to simultaneously brush and clean the inner surface of the recycling outer cylinder as the recycling inner cylinder rotates, avoiding the separated cutting fluid from adhering to the inner surface of the recycling outer cylinder.

[0009] Further, a pulley group is fixedly arranged at the output end of the second motor, and the pulley group is composed of two pulleys externally fitted with a belt. Through the above structure, it is convenient to achieve a linkage effect under the action of the pulley group.

[0010] Further, the adsorption magnetic roller is made of a magnet material that can collect metal scraps, and the adsorption magnetic roller is rotatably connected to the processing box through a rotating shaft. Through the above structure, it is convenient to adsorb and collect the iron metal scraps in the cutting fluid as the adsorption magnetic roller rotates.

Detailed Implementation Modes

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Please refer to Figures 1-6, the present utility model provides a technical solution: a cutting fluid recovery device for metal cutting processing, including a recovery outer cylinder 1, inside which a recovery inner cylinder 2 is snap-fitted through a rotating disk, and a first motor 3 is arranged at the lower end of the recovery outer cylinder 1, and the output end of the first motor 3 is fixedly connected to the rotating disk inside the recovery outer cylinder 1 through a rotating shaft; a treatment box 4 is fixedly arranged at the lower end of the recovery outer cylinder 1, and a liquid inlet pipe 5 penetrates through the lower end of the recovery outer cylinder 1 and is installed through the upper end of the treatment box 4; a set of cleaning brushes that are closely attached to the inner surface of the recovery outer cylinder 1 are arranged on the outer surface of the recovery inner cylinder 2.

[0025] When it is necessary to recover and process the cutting fluid of iron material (materials such as iron, cobalt, nickel, etc. that can be adsorbed by a magnet) workpieces, the cutting fluid containing waste chips that has been collected is poured into the recovery inner cylinder 2, and then the first motor 3 starts to work. Because the output end of the first motor 3 is snap-fitted and connected to the recovery inner cylinder 2 through a snap-fitting structure, at this time, the recovery inner cylinder 2 starts to rotate. As the recovery inner cylinder 2 rotates, the cutting fluid inside the recovery inner cylinder 2 starts to rotate centrifugally, that is, the cutting fluid and larger waste chips can be separated through the dense through holes opened on the recovery inner cylinder 2. And as the recovery inner cylinder 2 rotates, the bristles arranged outside the recovery inner cylinder 2 start to brush and clean the inner surface of the recovery outer cylinder 1, avoiding the cutting fluid containing smaller waste chips from adhering to the inner wall of the recovery outer cylinder 1. Then the filtered cutting fluid enters the inside of the recovery outer cylinder 1 and enters the treatment box 4 through the liquid inlet pipe 5 arranged at the lower end of the recovery outer cylinder 1;

[0026] A second motor 6 is fixedly arranged on the side of the treatment box 4, and an adsorption magnetic roller 8 is rotatably arranged at the output end of the second motor 6. An outlet pipe 9 is arranged at the lower end position of the treatment box 4, and a blanking plate 11 is fixedly installed on the treatment box 4; the output end of the second motor 6 is fixedly provided with a pulley group 7 through a rotating shaft, and the pulley group 7 is composed of two rotating wheels with a belt attached to the outside; the adsorption magnetic roller 8 is made of a magnet material that can collect metal waste chips, and the adsorption magnetic roller 8 is rotationally connected to the treatment box 4 through a rotating shaft.

[0027] As the cutting fluid enters the treatment box 4, the second motor 6 starts to work. Because the output end of the second motor 6 is fixedly provided with an adsorption magnetic roller 8 through a rotating shaft, at this time, the adsorption magnetic roller 8 starts to rotate counterclockwise. At this time, the cutting fluid flowing out of the liquid inlet pipe 5 first starts to contact the adsorption magnetic roller 8, and the fine waste chips inside the cutting fluid start to be adsorbed by the adsorption magnetic roller 8, that is, the purpose of fully cleaning the waste chips in the cutting fluid is achieved. As the adsorption magnetic roller 8 rotates, the blanking plate 11 that is closely attached to the adsorption magnetic roller 8 starts to scrape and clean the waste chips attached to the surface of the blanking plate 11, that is, the waste chips enter the collection box 10 through the blanking plate 11 for collection, and the adsorbed cutting fluid is discharged through the outlet pipe 9 arranged at the lower end of the treatment box 4.

[0028] A collection box 10 is fixedly arranged on the processing box 4, and two discharge pipes 13 are symmetrically arranged at the lower end of the collection box 10; a cleaning device 12 is arranged on the collection box 10, and the cleaning device 12 includes a reciprocating screw 121 and a reciprocating scraper 122. The reciprocating screw 121 is coaxially connected with the pulley group 7, and the reciprocating scraper 122 is attached to the inside of the collection box 10; the reciprocating screw 121 forms a rotating mechanism with the collection box 10 through a bearing installed on the collection box 10, and the reciprocating screw 121 is connected with the reciprocating scraper 122 through a threaded hole formed in the reciprocating scraper 122.

[0029] When it is necessary to clean the waste chips entering the collection box 10, since the pulley group 7 is installed at the output end of the second motor 6 and the pulley group 7 is connected with the reciprocating screw 121, the reciprocating screw 121 starts to rotate at this time. Also, since the reciprocating screw 121 is connected with the reciprocating scraper 122 through an externally arranged threaded structure, the reciprocating scraper 122 starts to move left and right reciprocally at this time, and the waste chips collected in the collection box 10 can be pushed to the side position of the collection box 10, and then discharged through the two discharge pipes 13.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
