Description

Technical Field

[0001] This utility model relates to machine tool processing equipment, and more particularly to a cutting fluid separation device for machine tool processing waste. Background Technology

[0002] Cutting fluid plays an indispensable role in machine tool processing. Through multiple functions such as lubrication, cooling, cleaning and rust prevention, it improves processing efficiency and workpiece quality, and also extends tool life. It is an indispensable auxiliary material in modern machining.

[0003] During the cutting process of workpiece forming, cutting fluid needs to be continuously sprayed onto the cutting tools and workpieces to maintain their normal quality. Existing machine tools are usually equipped with coolant recovery devices to reuse the discharged cutting fluid and filter the cut workpiece chips to ensure timely recycling of the cutting fluid. However, during processing, the filtering components on the machine tool can only perform simple solid-liquid separation. The chips cleaned out of the machine tool usually contain a large amount of liquid. This cutting fluid mixed in the chips will affect the subsequent transfer and storage of the chips. At the same time, the large amount of cutting fluid cleaned out of the equipment with the workpiece chips will undoubtedly cause a lot of waste of cutting fluid and increase processing costs.

Detailed Implementation

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0023] A cutting fluid separation device for machine tool processing waste, such as Figure 1-5 As shown, the device includes a base 1, a hopper 2, a separation chamber 3, a drain outlet 31, a receiving plate 32, a feed pipe 4, a motor 5, a separation cylinder 51, and a drain pipe 7. A cylindrical hopper 2 is fixed on the base 1. The lower part of the hopper 2 is funnel-shaped with a drain outlet at the bottom. The separation chamber 3 is located on the hopper 2. The lower part of the separation chamber 3 receives the material from the hopper 2. The upper part of the separation chamber 3 has a feed pipe 4, and several drain outlets 31 are evenly spaced on its lower wall. The motor 5 is located at the top of the separation chamber 3. The motor 5 is connected to the drain pipe 7. The separation chamber 3 is in a concentric position. The output shaft of the motor 5 is fed downwards into the separation chamber 3. A separation cylinder 51 is fixed on the output shaft of the motor 5. The separation cylinder 51 is at the same height as the drain port 31. The separation cylinder 51 is a hollow tube, and its size is similar to the lower inner diameter of the separation chamber 3. Its cylinder wall is perforated, and the holes in the cylinder wall are small, making it difficult for chips to pass through the cylinder wall of the separation cylinder 51. The motor 5 drives the separation cylinder 51 to rotate inside the separation chamber 3. The overall relative height of the separation cylinder 51 is... The upper and lower openings of the discharge port 31 are the same size. The lower part of the output shaft of the motor 5 is a square shaft. A receiving plate 32 is connected to the lower outer side of the separation chamber 3. The receiving plate 32 is arranged in a ring on the separation chamber 3, and its outer side is connected to the upper wall of the silo 2. The receiving plate 32 separates the outer space of the separation chamber 3 from the inner space of the silo 2. One side of the top surface of the receiving plate 32 is conical, and its inner ring height is higher than its outer ring height. The top side is at the same height as the bottom point of the discharge port 31. The lower opening of the separation cylinder 51 is provided with The discharge mechanism intermittently opens and closes at the bottom of the separation cylinder 51, working with the separation cylinder 51 to achieve solid-liquid separation and discharge of the chips. The upper part of the separation chamber 3 is equipped with a feed pipe 4, the lower end of which is located above the separation cylinder 51. That is to say, when the feed pipe 4 feeds, the material will pass through the inside of the separation cylinder 51. The feed pipe 4 is connected to the internal space of the separation chamber 3 and is used to connect to an external feeding device to discharge the chips that need to be separated into the separation chamber 3.

[0024] Among them, such as Figure 4-5As shown, the discharge mechanism includes: a bottom cover 6, a bushing 60, a fixed seat 61, and a hydraulic cylinder 62. The fixed seat 61 is concentrically fixed at the lower part of the hopper 2. The lower outer edge of the fixed seat 61 forms an annular discharge gap with the inner wall of the hopper 2. The hydraulic cylinder 62 is fixed inside the fixed seat 61. A rotary joint is installed at the upper end of the hydraulic rod of the hydraulic cylinder 62. The top of the rotary joint is connected to the bottom cover 6. The bottom cover 6 is located concentrically below the separating cylinder 51. The top of the bottom cover 6 has a protrusion with the same size and shape as the lower opening of the separating cylinder 51, and a bushing 60 with a shape matching the square shaft at the lower end of the motor 5 output shaft is provided at the protrusion. When the hydraulic cylinder 62... When 62 is fully extended, the bottom cover 6 completely seals the lower end of the separation cylinder 51, and the square shaft is embedded in the bushing 60. The bottom cover 6 rotates with the separation cylinder 51. Under the action of the rotary joint, the hydraulic rod of the hydraulic cylinder 62 will not rotate with the bottom cover 6. The upper part of the separation chamber 2 is provided with a drain pipe 7 to extract the separated liquid. The drain pipe 7 consists of two symmetrically arranged arc-shaped pipes and a three-way connector connecting the two arc-shaped pipes. The other end of the three-way connector needs to be connected to an external liquid extraction device. The separated cutting fluid is extracted from the separation device through the connected liquid extraction device. One end of each of the two arc-shaped pipes is inserted into the hopper 2, and the pipe openings at the insertion ends are close to the outer edge of the upper side of the receiving plate 32.

[0025] Initially, the hydraulic rod of hydraulic cylinder 62 is in the extended state, and the bottom cover 6 closes the lower opening of the separator 51. The stroke of the hydraulic rod of hydraulic cylinder 62 should be set such that when the hydraulic rod retracts, the bushing 60 and the square shaft of the output shaft of motor 5 are in a sliding connection state. When it is necessary to separate the liquid in the chips, firstly, the material containing a large amount of cutting fluid is introduced into the separator 51 through the feed pipe 4 by connecting to the external feeding equipment. The bottom cover 6 will catch the material. After a certain amount of chips are introduced, the feeding is stopped, and then motor 5 is started. Motor 5 rotates, driving the separator 51 and the bottom cover 6 to rotate at high speed. Under the action of centrifugal force, the cutting fluid in the chips in the separator 51 is expelled from the hollowed-out cylinder of the separator 51. The material is thrown out of the wall and falls onto the receiving plate through the discharge port 31. Under the guiding effect of the conical receiving plate, the liquid will gather at the outer ring of the receiving plate 32. The separated liquid will come into contact with the drain pipe 7. At this time, the liquid is pumped away through the drain pipe 7 connected to the liquid pumping device. After the separation is completed, the hydraulic cylinder 62 is controlled to retract the hydraulic rod, and the bottom cover 6 slides down but is still rotating. The material on the bottom cover 6 will be thrown into the hopper 2 under high speed rotation and discharged from the discharge port at the bottom of the hopper 2 under the action of gravity. After completing part of the chip separation work, the above separation action is repeated for continuous processing. The liquid entrained in the chips is efficiently separated by the separation device, and the separated liquid is reused by the liquid pumping device.

[0026] In one specific embodiment: as shown in Figure and Figure 3As shown, it also includes a filter 8 and a liquid outlet pipe 81. One end of the tee connector of the liquid outlet pipe 7 is equipped with a filter 8 that can filter out small impurities in the separated liquid. The filter 8 is connected to the liquid outlet pipe 7. The lower part of the filter 8 is connected to and connected to the liquid outlet pipe 81 that connects to the external liquid extraction equipment. A filtration device is installed on the pipeline of the liquid outlet pipe 7. When the liquid in the chips is separated, some small particles of chips will be mixed in, which will cause the cutting fluid to be contaminated. In the subsequent multiple reuse stages, it is easy to cause chip deposition and affect the function of the cutting fluid. The filter 8 purifies the cutting fluid extracted after separation to ensure the functionality of the cutting fluid.

[0027] In one specific embodiment, a shock-absorbing seat 9 is also included. The base 1 is equipped with a shock-absorbing seat 9 to reduce the outward transmission of vibration during the operation of the device. The shock-absorbing seat 9 consists of a base plate and several shock-absorbing springs evenly spaced on the base plate. Through the shock-absorbing springs on the shock-absorbing seat 9, the vibration generated by the rotation of the motor 5 during separation is effectively prevented from being effectively weakened by the rigid support and fed back and transmitted to other parts inside the equipment, causing accelerated wear. The use of the shock-absorbing seat 9 can reduce this wear and extend the overall service life of the equipment.

[0028] In one specific embodiment: such as Figure 3 As shown, it also includes an arc-shaped liquid collection frame 10 and an annular groove 101. An annular groove 101 is opened on the receiving plate 32 where it is in contact with the inner wall of the hopper 2. The annular groove 10 is symmetrically arranged in the annular groove 101 to collect and temporarily store a certain volume of liquid. The arc-shaped liquid collection frame 10 is used to collect the cutting liquid in a concentrated manner, so as to avoid the liquid after separation not being discharged from the receiving plate 32 in time and flowing back into the separation chamber 3 through the discharge port 31, which would cause the liquid to flow out from the discharge port of the hopper 2 and mix into the cuttings after the separation work is completed. At the same time, the liquid collection component makes it easier for the liquid discharge pipe 7 to discharge the liquid.

[0029] In one specific embodiment, the system also includes fixing rods 11 and elastic bands. The fixing rods 11 are symmetrically arranged at the bottom of the bottom cover 6, located away from the center of the bottom cover 6 and close to the inner wall of the hopper 2. As the bottom cover 6 rotates, elastic bands 111 are provided on the outer sides of each fixing rod 11. Before being subjected to external force, the elastic bands 111 wrap around the fixing rods 11. When the bottom cover 6 rotates, the elastic bands 111 are subjected to centrifugal force, causing their ends to be thrown outwards, and the entire elastic band 111 unfolds outwards. The unfolded elastic band 111 then contacts the interior of the hopper 2. As the bottom cover 6 rotates, it comes into circumferential contact with the inner wall of the hopper 2. When separation is complete, the bottom cover 6 moves downward with the hydraulic cylinder, and the upper part of the bottom cover 6 forms a discharge gap with the separation cylinder 51. The material falls from the separation cylinder 51 and is thrown out on the bottom cover 6. Some of the thrown material will stick to the inner wall of the hopper 2 near the discharge gap. At this time, the continuously rotating elastic band 111 will brush off the material sticking to the inner wall of the hopper 2, and the resulting knocking vibration can shake out the material stuck and retained in the area that the elastic band cannot reach in the hopper, ensuring that the chips can be discharged normally without manual cleaning.

[0030] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
