Description

Technical Field

[0001] The utility model relates to a metal cutting and filtering device. Background Art

[0002] When performing metal cutting, it is necessary to spray coolant at the contact point between the tool and the workpiece.

[0003] The functions of coolant are:

[0004] 1. Extend tool life

[0005] During metal cutting, friction between the tool and the workpiece generates frictional heat. Without coolant to dissipate the heat, this can lead to increased tool wear, thermal deformation, and even breakage. Adding coolant can effectively lower tool temperature, reduce wear and thermal deformation, and thus extend tool life.

[0006] 2. Extend material life

[0007] In addition to reducing tool temperature, coolant can also reduce thermal deformation of the material, prevent cracks and deformation, and thus extend the service life of the material during cutting.

[0008] 3. Improve processing quality

[0009] During cutting, cutting fluid can act as a lubricant, reduce the friction coefficient of the workpiece surface, reduce cutting force and cutting temperature, thereby reducing surface roughness, improving precision, and improving processing quality.

[0010] The coolant is circulated and in the prior art, the coolant that has been sprayed is recovered by a circulating pump, filtered by a filtering device, and then delivered to the nozzle for circulated spraying.

[0011] In actual operation, since the position of the filter screen of the filtration device is fixed, metal particles are easily stuck in the mesh of the filter screen, resulting in reduced filter efficiency. The filter screen needs to be disassembled for maintenance, which leads to frequent maintenance and delays in production.

[0012] Based on the above problems, we designed a metal cutting filtering device that can be quickly cleaned. Utility Model Content

[0013] The technical problem to be solved by the utility model is to provide a metal cutting filter device which can be quickly cleaned.

[0014] In order to solve the above problems, the present invention adopts the following technical solutions:

[0015] A metal cutting filter device includes a filter device, a liquid inlet pipe and a liquid outlet pipe. One end of the liquid inlet pipe is connected to the filter device, and the other end is connected to the coolant circulation pump of the machine tool.

The filter device is equipped with a sliding cleaning device.

[0016] Preferably, the filtering device includes an outer shell, a first connecting end is provided at the axis center of one end of the outer shell, a second connecting end is provided on the outer wall of the outer shell, close to the first connecting end, the liquid inlet pipe is connected to the first connecting end, the liquid outlet pipe is connected to the second connecting end, the end of the outer shell away from the first connecting end is provided with an opening, the sliding cleaning device is installed through the opening, the interior of the outer shell is threadedly connected with an inner tube corresponding to the first connecting end, the inner tube is communicated with the first connecting end, the end of the inner tube away from the first connecting end is provided with a filter cover, and the sliding cleaning device cooperates with the filter cover.

[0021] The beneficial effects of the utility model are:

[0022] This device filters the coolant through a filter cover, and the intercepted particles are located inside the filter cover. When the coolant injection volume is insufficient, the filter holes are clogged. At this time, the filter mesh can be unblocked by sliding the cleaning tube to restore the coolant delivery efficiency.

[0030] In addition, in the description of the present invention, “a plurality of” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] In this utility model, unless otherwise specified or limited, the terms "disposed," "socketed," "connected," "through," and "inserted" should be understood in a broad sense. For example, they can refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0032] See Figure 1 The metal cutting processing filter device shown includes a filter device 1, a liquid inlet pipe 2 and a liquid outlet pipe 3. One end of the liquid inlet pipe 2 is connected to the filter device 1, and the other end is connected to the coolant circulation pump of the machine tool. One end of the liquid outlet pipe 3 is connected to the filter device 1, and the other end is connected to the coolant nozzle of the machine tool. The filter device 1 is equipped with a sliding cleaning device 4.

[0033] In the above technical solution, the coolant that has been preliminarily filtered and pumped by the circulation pump is transported to the filter device 1 after cooling, filtered by the filter device 1, and then transported to the nozzle through the liquid outlet pipe 3 for spraying to cool the workpiece.

[0034] The sliding cleaning device 4 can slide along the filter device 1 to clean the filter device 1 while sliding, thereby ensuring that the filter device 1 has sufficient coolant passing capacity.

[0035] See Figure 2 As shown, the filtering device 1 includes a shell 101, a first connecting end 102 is provided at the axis center of one end of the shell 101, a second connecting end 103 is provided on the outer wall of the shell 101, close to the first connecting end 102, the liquid inlet pipe 2 is connected to the first connecting end 102, the liquid outlet pipe 3 is connected to the second connecting end 103, the end of the shell 101 away from the first connecting end 102 is provided with an opening (not shown), the sliding cleaning device 4 is installed through the opening, the interior of the shell 101 is threadedly connected to an inner tube 104 corresponding to the first connecting end 102, the inner tube 104 is communicated with the first connecting end 102, the end of the inner tube 104 away from the first connecting end 102 is provided with a filter cover 105, and the sliding cleaning device 4 cooperates with the filter cover 105.

[0036] The cooling fluid pumped by the circulation pump enters the inner tube 104 through the first connection end 102 , passes through the filter cover 105 , and is input into the outer shell 101 , and then is delivered to the nozzle from the second connection end 103 .

[0037] During the above-mentioned processing, particulate matter is intercepted in the filter cover 105. Some particulate matter will be stuck in the filter holes of the filter cover 105 due to angle problems. The filter cover 105 is cleaned by the reciprocating movement of the sliding cleaning device 4 to ensure that the filter cover 105 has sufficient passing capacity.

[0038] See Figure 2 As shown, the sliding cleaning device 4 includes an end cover 401 closed at the opening, a sliding rod 402 is provided at the axis of the end cover 401, a sealing ring 403 is provided on the inner wall of the end cover 401 to form a seal with the sliding rod 402, an operating handle 404 is provided at one end of the sliding rod 402, and the other end is inserted into the outer shell 101, and a cleaning tube 405 is provided at the end of the sliding rod 402 inserted into the outer shell 101, and bristles 406 are implanted on the inner wall of the cleaning tube 405. When the sliding rod 402 slides, the bristles 406 act on the surface of the filter cover 105.

[0039] In the above technical solution, the reciprocating movement of the slide rod 402 enables the bristles 405 to clean the surface of the filter cover 105 and dredge the filter holes of the filter cover 105, thereby ensuring that the filter cover 105 has sufficient passing efficiency.

[0040] See Figure 2 As shown, a first sealing ring 4441 is provided at the end of the cleaning tube 405 away from the filter cover 105. When the cleaning tube 405 moves to the left to the extreme position, the first sealing ring 4441 contacts the inner wall of the end cover 401 and forms a seal therewith.

[0041] In the above technical solution, when the cleaning tube 405 slides to the left to the extreme position, the first sealing ring 4441 can play a sealing role to prevent liquid leakage at the position where the sliding rod 402 passes through the end cover 401.

[0042] See Figure 2 As shown, a web 441 is provided on the outer wall of the cleaning tube 405, and a second sealing ring 442 is provided on the outer wall of the web 441. The second sealing ring 441 forms a seal with the inner wall of the outer shell 101. When the cleaning tube 405 moves to the right to the extreme position, the web 441 is located on the left side of the second connecting end 103.

[0043] In the above technical solution, the cooperation between the web 441 and the second sealing ring 442 can prevent the coolant from entering the left side of the web 441, thereby reducing the possibility of coolant leakage.

[0044] See Figure 2 As shown, a magnet block 499 is embedded in the inner wall of the cleaning tube 405 .

[0045] The magnet block 499 can magnetically capture magnetically adsorbable particles to provide a further cleaning effect.
