Description

Technical Field

[0001] The present invention relates to the technical field of machining, and particularly relates to a chip removal, shredding and lifting device. Background Art

[0002] There are two forms of the circulation mode of cutting fluid: single-machine circulation filtration and centralized filtration. Single-machine circulation filtration means that the filtration systems of each machine tool are independent. This independent circulation filtration mode is generally applicable to working conditions with a small number of machine tools or the use of different cutting fluids. For large mechanical processing plants using wet machining, the centralized filtration method is more suitable. The centralized filtration system is the trend of modern wet machining filtration. Compared with the single-machine circulation filtration mode, the centralized filtration has the following advantages: small floor area and convenient management; fewer points for adding cutting fluid, which can reduce the number of cutting fluid management personnel; waste cutting fluid can be centrally treated with less environmental pollution; the discharged iron chips are concentrated, which is convenient for transportation and treatment; the usage situation of cutting fluid can be centrally monitored; the filtration accuracy is easy to control; and it is easy to achieve automatic control.

[0003] The centralized filtration and cooling system adopts the way of large circulation, large flow rate and large stroke liquid reflux. The heat of the cutting fluid dissipates quickly, the temperature of the liquid supply system is low, and an internal circulation is provided during the shutdown period, so that the large-flow cutting fluid can flow continuously, effectively inhibiting the growth of bacteria. At the same time, it is also easy to automatically control the performance indicators of the cutting fluid to ensure the quality of the cutting fluid. In addition, centralized liquid supply is also convenient for centralized treatment of sewage, protecting the ecological environment and meeting the environmental protection requirements.

[0004] The lifting device is one of the important components in the centralized filtration device of the coolant; the function of the lifting device is to transport the chips and sewage together into the centralized pipeline. The chips and sewage enter the centralized filtration device from the centralized pipeline, and the centralized filtration device processes the chips and sewage and then supplies the clean coolant back to the machine tool. The lifting device mainly consists of a lifting pump and a liquid level control system. Usually, the prerequisite for the lifting device to function smoothly is that the chips entering the lifting device are short broken chips. If long cluster chips directly enter the lifting device, it will cause damage to the lifting pump and blockage of the pipeline, rendering the lifting device ineffective and thus unable to complete the centralized filtration of the coolant.

[0005] When long cluster chips are generated during the machining of parts by the machine tool, generally a chain plate chip conveyor is used to separately lift the long cluster chips and transport them to a shredder, and the shredded chips fall back into the lifting device again. However, at this time, the chain plate chip conveyor cannot transport the sewage generated by the machine tool into the lifting device either, and the sewage of the machine tool cannot be treated, so centralized filtration cannot be achieved. The machining method of the machine tool is the main factor determining the shape of the chips. However, changing the machining method of the machine tool will increase the manufacturing cost. Therefore, without changing the machining method of the machine tool, how to transport the long cluster chips and sewage to the centralized pipeline at the same time for subsequent centralized filtration has become a problem to be solved.

[0036] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0037] As Figures 1 to 9 shown, the present invention discloses a chip removal, shredding and lifting device, which includes a chain plate chip removal mechanism, a shredding mechanism 14, a lifting mechanism and an electric control mechanism 17;

[0038] The chain plate chip removal mechanism includes a housing 2, a chip removal chain plate 3 and a driving motor 1 6. The chip removal chain plate 3 is arranged inside the housing 2. The output end of the driving motor 1 6 passes through the housing 2 and is in transmission connection with the chip removal chain plate 3. An inlet 7 is provided on the housing 2. The inlet 7 is used to be placed below the machine tool 1 and communicated with the sewage outlet of the machine tool 1. The sewage and long chip clusters generated by the machine tool 1 during processing of parts fall on the chip removal chain plate 3 through the inlet 7. The long chip clusters are conveyed to the shredding mechanism 14 under the action of the chip removal chain plate 3. The sewage enters the housing 2 through the chain plate gaps and flows to the lifting mechanism;

[0039] The shredding mechanism 14 is located at the chip outlet of the chain plate chip removal mechanism. The shredding mechanism 14 is in the form of a single-shaft shredder. The shredding mechanism 14 is located in the space formed by the housing 2 and the water tank 13, and the shredding mechanism 14 is located between the chain plate chip removal mechanism and the lifting pump 16, making the overall structure more compact and occupying less space. The shredding mechanism 14 includes a second driving motor 1401, a shredding rotating shaft 1402 and cutting knives 1403. The output end of the second driving motor 1401 is connected to a speed reducer, and the speed reducer is installed on a fixed bracket 15 outside the housing 2. The speed reducer is drivingly connected to the shredding rotating shaft 1402. The shredding rotating shaft 1402 is arranged along the width direction of the housing 2. Both ends of the shredding rotating shaft 1402 are rotatably connected to the housing 2 through bearings. The cutting knives 1403 are provided on the shredding rotating shaft 1402. The second driving motor 1401 drives the shredding rotating shaft 1402 and the cutting knives 1403 to rotate, shredding the long mass chips falling from the chip outlet into short chips, and the short chips fall into the water tank 13 for the lifting pump 16 to transport to the centralized pipeline. The shredding mechanism 14 is equipped with an overload protection device to ensure the service life of the shredding mechanism 14;

[0040] The lifting mechanism includes a water tank 13 and a lifting pump 16. The third driving motor 20 is installed on the water tank 13. The output end of the third driving motor 20 is drivingly connected to the lifting pump 16 to drive the lifting pump 16 to work. The lifting pump 16 is arranged in the water tank 13. The water tank 13 is communicated with the housing 2, so that the waste liquid generated by the machine tool 1 during machining flows into the water tank 13. The lifting pump 16 lifts the short chips and the waste liquid together to the centralized pipeline for subsequent centralized filtration treatment to realize the recycling of the cutting fluid and reduce the processing cost;

[0041] The electric control mechanism 17 is respectively communicatively connected to the first driving motor 6, the second driving motor 1401 and the lifting pump 16. The electric control mechanism 17 controls the driving motor and the lifting pump 16 to work as required to ensure the stable operation of the entire device and improve the convenience of use. When the machine tool is started, a start signal is sent to the electric control mechanism 17. The electric control mechanism 17 controls the operation of the chain plate chip removal mechanism and the shredding mechanism 14. When the water level in the water tank 13 reaches the set liquid level height, the lifting pump 16 starts to transport the waste liquid and chips. After the electric control mechanism 17 controls the second driving motor 1401 to rotate forward for 1 minute and then reverse for 1 minute, the long mass chips can be shredded faster, and the forward and reverse rotation time can be set as needed.

[0042] In this embodiment, the water tank 13 and the housing 2 are of an integral structure, which increases the structural strength of the lifting device, reduces the number of parts and the processing cost.

[0043] Optionally, the water tank 13 and the housing 2 can also be welded together or installed together through fasteners.

[0044] Furthermore, a detachable cover plate 21 is provided on the housing 2 at the chip outlet of the chain plate chip removal mechanism. The cover plate 21 can be opened to directly replace the cutting tool 1403, which facilitates the maintenance of the shredding mechanism 14 and improves the convenience of use.

[0045] The chain plate chip removal mechanism includes a horizontal section and a lifting section. The inlet 7 is arranged in the horizontal section, and the horizontal section is inserted into the bottom of the machine tool 1. The chips and waste liquid generated by the machine tool 1 fall into the housing 2 through the inlet 7. The lifting section raises the chips and then drops them into the shredding mechanism 14 for shredding. An upper cover plate 8 and a lower cover plate 9 are provided on the housing 2 of the lifting section. The upper cover plate 8 is installed on the housing 2 by screws and plays a fixing role. Vertical plates are welded on both sides of the upper cover plate 8 to prevent chips from entering the chain track of the chip removal chain plate 3 and ensure the normal operation of the chip removal chain plate 3. The lower cover plate 9 is welded on the vertical plate. The distance between the lower cover plate 9 and the chip removal chain plate 3 can be set according to requirements and then welded. A lifting channel is formed between the lower cover plate 9 and the chip removal chain plate 3. An inlet 10 is provided at the end of the lifting channel. The lower cover plate 9 is butted against the upper cover plate 8 at the inlet 10, making the inlet 10 in a flared shape, so that long lumpy chips can gradually enter the lifting section from the horizontal section through the inlet 10. The lower cover plate 9 cooperates with the chip removal chain plate 3 to reduce the chip conveying height, making the shape of the long lumpy chips entering the lifting channel smaller, effectively avoiding the jamming, overload or damage of the shredding mechanism 14 caused by oversize long lumpy chips, ensuring the service life of the shredding mechanism 14 and ensuring the normal operation of the entire lifting device.

[0046] Furthermore, a plurality of cutting tools 1403 are provided. The plurality of cutting tools 1403 are circumferentially spaced along the shredding rotating shaft 1402, which improves the shredding effect on long lumpy chips. The cutting tools 1403 are installed on the shredding rotating shaft 1402 by bolts or screws, which facilitates disassembly, installation and replacement and improves the service life of the lifting device.

[0047] The shredding mechanism 14 further includes a box body with an opening at the upper end. The shredding rotating shaft 1402 and the cutting knife 1403 are arranged inside the box body. The box body includes a side plate 1404 and a support plate 1407 which are connected. The support plate 1407 is located at the bottom of the box body. Both ends of the support plate 1407 are installed on the housing 2 through bolts, which is convenient for disassembly, installation and maintenance. The side plate 1404 is installed on the housing 2 through bolts. A lining plate 1405 and a screen 1406 are arranged inside the side plate 1404. The lining plate 1405 is located between the side plate 1404 and the screen 1406. The lining plate 1405 is installed on the side plate 1404 through bolts, which is convenient for disassembly, installation and maintenance and reduces the maintenance cost. The support plate 1407 is internally provided with a screen 1406. The shredded short debris and the waste liquid contained in the debris fall into the water tank 13 below through the screen 1406, so as to facilitate the lifting pump 16 for lifting and conveying. The unshredded long lumps of debris remain on the screen 1406. The shearing force between the cutting knife 1403 and the lining plate 1405, and between the cutting knife 1403 and the screen 1406 tears the long debris into short debris, and the length of the debris is screened by the screen 1406 to avoid blocking the lifting pump 16 and ensure the service life of the lifting pump 16.

[0048] Two support plates 1407 are respectively arranged on both sides of the water tank 13. The two support plates 1407 on each side form a V shape, which improves the structural strength and facilitates the downward dropping of the debris. The reinforcing plate 1408 is inserted on the support plate 1407 to increase the strength of the support plate 1407 and improve the torsional strength of the housing 2.

[0049] Preferably, the chip discharging chain plate 3 includes an upper layer chain plate and a lower layer chain plate. Concave portions 4 and convex portions 5 are arranged on the lower layer chain plate. The concave portion 4 is adjacent to the shredding mechanism 14, and the convex portion 5 is adjacent to the spray head 1302, which further reduces the accumulation of debris on the chip discharging chain plate 3 and ensures the normal operation of the chip discharging chain plate 3.

[0050] The chip discharging and shredding and lifting device further includes a scraping tooth 11. The scraping tooth 11 is located between the concave portion 4 and the shredding mechanism 14, which can effectively reduce the reverse belt of chips by the chip discharging chain plate 3 and ensure the normal operation of the chip discharging chain plate 3.

[0051] The bottom plate of the housing 2 is connected to the bottom plate of the water tank 13 through a transition plate 12. The inclination angle δ of the transition plate 12 is 0° to 90°, preferably 30°. The height of the bottom plate of the housing 2 is greater than the height of the bottom plate of the water tank 13, which is convenient for the waste liquid generated by the machine tool 1 to automatically flow into the water tank 13 under the action of gravity, so as to realize that the lifting pump 16 lifts the waste liquid to the centralized pipeline. The inclined transition plate 12 can improve the flow effect of the waste liquid.

[0052] Further, a plurality of inclined plates 19 are provided at the corners of the bottom of the water tank 13, which is beneficial for the chips to fall towards the suction port at the bottom of the lifting pump 16, avoiding the accumulation of chips at the corners of the water tank 13.

[0053] The chip discharging, shredding and lifting device further includes a liquid supplementing mechanism to ensure an appropriate chip-liquid ratio to meet the conveying requirements of the lifting pump 16. The liquid supplementing can start simultaneously with the start of the lifting pump 16, and the stop of the liquid supplementing can be controlled by setting the liquid supplementing duration. The liquid supplementing mechanism includes a first liquid supplementing pipeline 1301 and a second liquid supplementing pipeline 1303. The first liquid supplementing pipeline 1301 is located in the water tank 13 and is arranged along the width direction of the water tank 13. The first liquid supplementing pipeline 1301 is close to the bottom of the water tank 13. A plurality of spray heads 1302 are provided on the first liquid supplementing pipeline 1301, and the spray heads 1302 face the transition plate 12. While supplementing the liquid, the chips accumulated at the bottom of the water tank 13 can be washed to the suction port at the bottom of the lifting pump 16, effectively reducing the precipitation of chips inside the water tank 13. The second liquid supplementing pipeline 1303 is arranged on the water tank 13 and is communicated with the water tank 13 to directly supplement the liquid to the water tank 13.

[0054] The chip discharging, shredding and lifting device further includes a liquid level control mechanism 18 and a liquid level detection switch. The liquid level detection switch is used to detect the liquid level height in the water tank 13. The liquid level detection switch is communicatively connected with the liquid level control mechanism 18, and the liquid level control mechanism 18 is communicatively connected with the electric control mechanism 17. The liquid level control mechanism 18 can effectively control the liquid level height in the water tank 13 to ensure an effective liquid level for the conveying of the lifting pump 16 and prevent the overflow of the liquid level that is too high from the water tank 13: when the liquid level detection switch detects that the liquid level in the water tank 13 drops to the set liquid level, it controls the liquid supplementing switch to automatically supplement the liquid to the water tank 13 through the second liquid supplementing pipeline 1303 to meet the chip-liquid ratio of the lifting pump 16 and ensure the liquid level height for the normal operation of the lifting pump 16, so that the lifting pump 16 has enough running time to convey the chip-liquid to the centralized pipeline; when the liquid level detection switch detects that the liquid level in the water tank 13 drops to the set lowest point, the liquid level detection switch sends a signal to the liquid level control mechanism 18, and the liquid level control mechanism 18 sends a signal to the electric control mechanism 17, and the electric control mechanism 17 controls the lifting pump 16 to stop operating, preventing the lifting pump 16 from idling, avoiding the damage of the sealing parts due to overheating caused by the dry grinding during idling of the lifting pump 16, and finally resulting in the abnormal operation of the lifting pump 16.

[0055] Further, the electric control mechanism 17 is communicatively connected with the machine tool 1. The electric control mechanism 17 includes a display screen, and the display screen can real-time display the operation status of the lifting device and form a linkage with the working state of the machine tool 1. For example, when the machine tool stops operating, the machine tool transmits a stop signal to the electric control mechanism 17, and the electric control mechanism 17 controls the lifting pump 16 to stop operating, meeting the intelligent design requirements of modern factories.

[0056] The lifting device of the present invention has a compact structure, ingenious design, small floor area, and is easy to install. It can be directly installed at the bottom of the machine tool 1, effectively tear long curly chips into short chips, and simultaneously transport the chips and sewage to the centralized pipeline for centralized filtration, so as to improve the recycling of cutting fluid, solve the problems of long curly chips blocking the pipeline and damaging the sewage lift pump 16, and finally solve the problem that long curly chips cannot be centrally filtered.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
