Description

Technical Field

[0001] This utility model relates to the field of cutting fluid cleaning technology, specifically a cutting fluid cleaning device for machine tools. Background Technology

[0002] Machine tools are the core equipment for cutting metal workpieces. During the machining process, the sprayed cutting fluid serves as a key process medium, playing a dual role in cooling and ensuring machining quality. Metal chips and waste cutting fluid are both important recyclable resources. In order to achieve sustainable production and efficient resource utilization, it is necessary to implement systematic separation and recycling of metal chips and waste cutting fluid.

[0003] For example, the patent with authorization announcement number CN223057292U describes a metal cutting machine tool that can add cutting fluid. By setting up a recycling mechanism, the metal chips and cutting fluid are separated by a filter plate, and the metal chips are collected in a slag collection box, which facilitates the recycling and reuse of metal chips and cutting fluid and improves resource utilization.

[0004] The existing technology has the following problems:

[0005] In existing technology, metal debris is attracted to the filter plate by an electromagnet, and then transferred by an electric guide rail driven by a connecting plate. When the debris is transferred to the top of the slag collection box, the electromagnet is de-energized to release the debris for collection. However, if this recycling operation needs to be carried out without stopping the equipment, the metal debris being transferred will be continuously exposed to the impact of the circulating cutting fluid. This results in the cutting fluid being heavily adhered to the surface of the debris, significantly reducing the solid-liquid separation efficiency. After long-term operation, a large amount of mixed liquid will accumulate in the slag collection box, which not only increases the burden of subsequent processing, but also directly affects the purity of the recycled metal debris and the convenience of operation.

[0006] Based on this, a cutting fluid cleaning device for machine tools is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0007] The purpose of this invention is to provide a cutting fluid cleaning device for machine tools to solve the problems in the background art.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model applies pressure during the metal scrap transfer process using a second spiral roller. Through continuous mechanical extrusion, the residual cutting fluid on the surface of the scrap is forced out. The extruded cutting fluid flows through a filter plate into a collection chamber for initial collection. A drive pump then pumps the cutting fluid in the collection chamber to a recovery cylinder through a water pipe, achieving effective recovery of the cutting fluid. At the same time, the metal scraps after being extruded and dehydrated are discharged and collected through a feeding seat, ensuring the separation efficiency of metal scraps and cutting fluid, reducing the residual liquid content of the scraps, and improving the recovery quality and purity.

[0020] 2. This utility model uses a first rotating motor to drive the pulley to rotate, which in turn drives the transmission ring to rotate, thereby driving the filter screen to rotate continuously. The water spray seat sprays high-pressure water into the rotating filter screen to impact the filter holes, effectively removing metal debris that clogs the holes, realizing the self-cleaning function of the filter screen, and ensuring its filtration efficiency remains stable.

The pulley 203 is driven to rotate by the first rotating motor 204, and the pulley 203 drives the transmission ring 202 to rotate through the belt. The transmission ring 202 drives the filter screen 201 to rotate, and water is sprayed onto the filter screen 201 through the water spray seat 205. The high-pressure water jet impacts the filter holes of the filter screen 201 to prevent metal debris from clogging the filter screen 201, thus playing an anti-clogging role.

[0030] In one embodiment, such as Figure 4 and Figure 5 As shown, a transfer seat 206 is provided above the filter screen 201, and a scraper 210 is provided on the side of the transfer seat 206. The scraper 210 rubs against the surface of the transmission ring 202. The transfer seat 206 is fixedly connected to the inner wall of the machine tool 101. A first spiral roller 207 is rotatably provided inside the transfer seat 206. During the rotation of the filter screen 201, the scraper 210 rubs against the surface of the filter screen 201, guiding the metal debris to move into the transfer seat 206, providing power for collecting the metal debris.

[0031] In one embodiment, such as Figure 4 and Figure 5As shown, a second rotating motor 209 is installed on the side of the transfer seat 206. The output end of the second rotating motor 209 is fixedly connected to the first spiral roller 207. The lower end of the transfer seat 206 is provided with a feeding port 208. The second rotating motor 209 provides power and drives the first spiral roller 207 to rotate.

[0032] In one embodiment, such as Figure 4 and Figure 5 As shown, a separation seat 401 is provided below the transfer seat 206, and a feeding seat 402 is provided at the upper end of the separation seat 401. The feeding seat 402 is connected to the feeding port 208. A second spiral roller 403 is rotatably provided inside the separation seat 401. Metal scraps move to the inside of the separation seat 401 through the feeding port 208 and the feeding seat 402, and are transferred by the rotation of the second spiral roller 403.

[0033] In one embodiment, such as Figure 4 and Figure 5 As shown, a third rotary motor 404 is installed on the side of the separation seat 401. The output end of the third rotary motor 404 is fixedly connected to the second spiral roller 403. The lower end of the separation seat 401 is connected to the feeding seat 405. The third rotary motor 404 provides power for the rotation of the second spiral roller 403. During the transfer process, the metal scraps are drained, further separating the metal scraps from the cutting fluid and improving the recycling efficiency. The separated metal scraps are discharged and collected through the feeding seat 405 for easy recycling by the staff.

[0034] In one embodiment, such as Figure 4 and Figure 5 As shown, the surface of the separation seat 401 is provided with a filter plate 406, and a collection chamber 407 is provided outside the filter plate 406. The collection chamber 407 is connected to one end of a water pumping pipe 408, and the other end of the water pumping pipe 408 is connected to a recovery cylinder 301. A drive pump is installed on the water pumping pipe 408. During the transfer of metal scrap, the second spiral roller 403 exerts a certain squeezing effect on the metal scrap. The metal scrap is subjected to pressure and drips out the cutting fluid remaining on the surface. The cutting fluid flows through the filter plate 406 to the inside of the collection chamber 407 for recovery. Through the cooperation of the water pumping pipe 408 and the drive pump, the dripped cutting fluid is transported to the inside of the recovery cylinder 301 for recovery, thereby improving the recovery quality.

[0035] The above embodiment discloses a cutting fluid cleaning device for a machine tool. The machine tool cuts a workpiece using a chuck and punch. During the cutting process, a nozzle sprays cutting fluid onto the cutting position. Metal chips generated during processing flow with the cutting fluid to a filter screen 201 for centralized filtration. The metal chips separate on the filter screen 201, and the separated cutting fluid moves to a recovery cylinder 301. It is then recovered via a recovery pipeline connected to a feed valve 302, completing the cutting fluid cleaning operation. A first rotating motor 204 drives a pulley 203 to rotate, which in turn drives a transmission ring 202 via a belt. The transmission ring 202 drives the filter screen 201 to rotate, spraying water onto the filter screen 201 through a water spray base 205. High-pressure water impacts the filter holes of the filter screen 201, preventing metal chips from clogging it and providing an anti-clogging function. During the rotation of the filter screen 201, a scraper 210 rubs against the surface of the filter screen 201, guiding the metal chips to a transfer base 206 for collection. The first spiral roller 207 is driven to rotate by the second rotating motor 209. The first spiral roller 207 moves the metal scrap inside the transfer seat 206 to the feed port 208, thus transferring the metal scrap.

The third rotating motor 404 provides power for the rotation of the second spiral roller 403. During the transfer process, the metal scrap is drained. During the transfer process, the second spiral roller 403 exerts a certain squeezing effect on the metal scrap, and the metal scrap is pressured to drain the residual cutting fluid on the surface. The cutting fluid flows through the filter plate 406 to the collection chamber 407 for recycling. The drained cutting fluid is transported to the recovery cylinder 301 for recycling through the cooperation of the water pipe 408 and the drive pump. The separated metal scrap is discharged and collected through the discharge seat 405 for easy recycling by the staff.
