[0002] A large amount of cutting chip waste slag will be generated during the cold processing of machine tools.

Detailed implementation manners

[0028] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below with reference to the drawings.

[0029] As Figure 1 、 Figure 2 shown, a new type of cutting chip cake press includes a machine body 1 and a feeding unit, an extrusion unit, a power unit and a recycling bin 2 arranged on the machine body 1. The feeding unit includes a first feed hopper 3 with an upper end as a feeding port and a second feed hopper 4. The upper end of the second feed hopper 4 is docked with the lower end of the first feed hopper 3, and their inner cavities are communicated. A pushing mechanism is arranged at the upper part of the first feed hopper 3, and a feeding mechanism is arranged at the bottom of the second feed hopper 4. The extrusion unit includes a cake pressing die 5 and an extrusion mechanism at one end thereof. The other end of the cake pressing die 5 is provided with a discharge port, and a material blocking mechanism is arranged at the discharge port. The recycling bin 2 is arranged at the bottoms of the second feed hopper 4 and the cake pressing die 5 for collecting cutting oil or cutting fluid extruded during the pressing process. The pushing mechanism, the feeding mechanism, the extrusion mechanism and the material blocking mechanism are all connected to the power unit. Among them, the upper feeding port of the first feed hopper can be manually fed or can be matched and docked with the chip conveyor around the processing machine tool, and the cutting chips are directly input into the first feed hopper to realize automatic feeding. The pushing mechanism is used to push the cutting chips from the first feed hopper into the second feed hopper, and the mechanized feeding has high safety performance; then it is pushed into the cake pressing die by the feeding mechanism, and the extrusion mechanism is started to extrude the cutting chips into a cake shape. The extruded cutting oil or cutting fluid enters the recycling bin for recycling, which is convenient for recycling; finally, the material blocking mechanism is opened, and the cake-shaped cutting chips are pushed out by the extrusion mechanism, which is convenient for storing and transporting the slag cakes.

[0030] During the specific production, as Figure 1As shown, a sheet metal three-dimensional housing 6 is provided outside the feeding unit, the extrusion unit, and the power unit. A control box 7 is provided at one end of the housing 6. The pusher mechanism, the feeding mechanism, the extrusion mechanism, the material blocking mechanism, and the power unit are all controlled by a controller (not shown in the figure) in the control box 7. Legs 31 are provided at the bottom of the machine body 1, and adjustable legs can be used to facilitate the overall leveling of the equipment. At the same time, a power supply is also provided in the control box 7, and a touch screen 30 is provided on the front side wall of the housing 6. The pusher mechanism, the feeding mechanism, the extrusion mechanism, the material blocking mechanism, and the power unit can all be controlled through the touch screen 30.

[0031] In a specific embodiment of the present invention, as Figure 1 , 2 shown, the first feeding hopper 3 is in the shape of a quadrangular pyramid with a large top and a small bottom. The pusher mechanism includes a pusher hydraulic cylinder 8 and a push plate 9. The cylinder body of the pusher hydraulic cylinder 8 is inclined and arranged on one inner wall of the first feeding hopper 3. The push plate 9 is fixed to the end of the piston rod of the pusher hydraulic cylinder 8. The width of the push plate 9 matches the outlet of the first feeding hopper 3. The pusher hydraulic cylinder 8 is connected to the power unit. During specific design, a guard plate 29 is installed outside the cylinder body of the pusher hydraulic cylinder 8 to prevent cutting chips from being hooked on the cylinder body of the pusher hydraulic cylinder 8 and affecting its service life. At the same time, the slope of the side surface of the first feeding hopper 3 where the pusher hydraulic cylinder 8 is installed is smaller than the other three sides, which can provide a feeding space and also provide enough stroke for the pusher hydraulic cylinder 8.

[0032] As a preferred structure, the bottom of the second feeding hopper 4 is a semi-cylindrical cavity. The feeding mechanism is a spiral feeding rod 10. The spiral feeding rod 10 is arranged in the lower semi-cylindrical cavity of the second feeding hopper 4 to facilitate smoother feeding of cutting chips. A driving mechanism for driving the spiral feeding rod 10 to rotate is provided at one end of the bottom of the second feeding hopper 4, and an outlet communicating with the briquetting die 5 is provided at the other end of the bottom of the second feeding hopper 4. The driving mechanism drives the spiral feeding rod 10 to rotate, and the cutting chips entering from above can be sequentially pushed into the briquetting die 5 along with the spiral feeding rod 10.

[0033] In Figure 2 the shown embodiment, the driving mechanism adopts a chain transmission mechanism, including a chain (not shown in the figure), a driving sprocket 11, and a driven sprocket 12. The driving sprocket 11 is driven by the power unit, and the driven sprocket 12 is arranged outside the second feeding hopper 4 and is coaxially fixed with the spiral feeding rod 10. The hydraulic motor 26 of the power unit can drive the driving sprocket 11 to rotate, and then drive the driven sprocket 12 to rotate through the chain, thereby driving the spiral feeding rod 10 to rotate.

[0034] In a specific embodiment of the present invention, as Figure 2As shown, the extrusion mechanism includes an extrusion hydraulic cylinder 13 and a pusher rod 14. The pusher rod 14 is connected to the end of the piston rod of the extrusion hydraulic cylinder 13, and the pusher rod 14 has a small clearance fit with the inner cavity of the cake pressing die 5. A support frame 15 is vertically provided at the discharge port of the cake pressing die 5. The material blocking mechanism is arranged on the support frame 15. A liquid leakage plate 16 is provided at the bottom of the support frame 15. The recycling box 2 is arranged below the liquid leakage plate 16. The extrusion hydraulic cylinder 13 is connected to the power unit. During assembly, the end of the cylinder body of the extrusion hydraulic cylinder 13 is fixedly connected to the end of the cake pressing die 5 through a flange. The pusher rod 14 extrudes the cutting chips entering the inner cavity under the drive of the extrusion hydraulic cylinder 13. When the extrusion hydraulic cylinder reaches its full stroke, the pusher rod is just horizontal with the discharge port. The cutting oil or cutting fluid extruded during the extrusion process will leak into the lower recycling box through the gap between the two and through the liquid leakage plate.

[0035] In Figure 2 the illustrated embodiment, the material blocking mechanism includes an opening hydraulic cylinder 17 and a material blocking door plate 18. The opening hydraulic cylinder 17 is arranged on the top of the support frame 15. The material blocking door plate 18 is connected to the end of the piston rod of the opening hydraulic cylinder 17. The periphery of the material blocking door plate 18 is in sealing fit with the inner wall of the support frame 15. A liquid drainage groove is provided at the inner edge of the material blocking door plate 18 for guiding the extruded cutting oil or cutting fluid into the lower recycling box 2. The opening hydraulic cylinder 17 is connected to the power unit. As Figure 6 , 7 shown, during the extrusion of the cutting chips in the cake pressing die, the material blocking door plate 18 is in a closed state. When the slag cake in the cake pressing die is extruded and formed, the opening hydraulic cylinder 17 is started to lift the material blocking door plate 18, and at the same time, the extrusion hydraulic cylinder 13 is further advanced to push out the slag cake.

[0036] In a specific embodiment of the present invention, as Figures 3 - 5 shown, the cake pressing die 5 includes a rectangular parallelepiped-shaped bin body 19. A hollow area 20 that penetrates left and right is provided at the front of the bin body 19. A cylindrical inner cavity is provided inside the rear part of the bin body 19. A forming inner sleeve 21 is provided on the inner wall of the inner cavity. The pusher rod 14 is in sliding fit with the inner wall of the forming inner sleeve 21 (the fit clearance is 0.05 mm). A material passing hole 22 that penetrates the inner cavity and the first feed hopper 3 is provided on the rear side of the cake pressing die 5. A through hole 23 corresponding to the material passing hole is provided on the forming inner sleeve 21. A plurality of small holes (not shown in the figure) are provided on the side wall of the forming inner sleeve 21. The cutting oil or cutting fluid extruded during the extrusion of the cutting chips will be discharged through the small holes, and at the same time, it is also convenient for exhaust.

[0037] During specific production, the pusher rod 14 and the forming inner sleeve 21 are both subjected to heat treatment processes to improve wear resistance, pressure resistance and toughness. The spiral feed rod 10 is subjected to high-frequency heat treatment and is integrally processed from steel, and its right-handed thread blades are thickened.

[0038] Further optimize the above solution. A pressure sensor (not shown in the figure) is provided in the rear inner cavity of the bin body 19. The pressure sensor can be linked with the drive mechanism and the opening hydraulic cylinder 17. During application, materials are fed into the bin body from the side. The pressure sensor controls the feeding volume ratio of the inner cavity. When the inner cavity exceeds the set pressure, the pressure sensor sends signals to the drive mechanism and the extrusion hydraulic cylinder. The drive mechanism stops feeding, and the extrusion hydraulic cylinder starts to carry out high-density pressing on the cutting chips. When the inner cavity pressure reaches the maximum, the pressure sensor sends signals to the extrusion hydraulic cylinder and the opening hydraulic cylinder. The opening hydraulic cylinder starts to drive the baffle door panel to rise, and then the extrusion hydraulic cylinder continues to move forward to push out the slag cake. The density of the extruded slag cake can reach 80 - 95%, which is convenient for storage and transportation.

[0039] In a specific embodiment of the present utility model, as Figure 2 shown, the power unit includes a plunger pump 24, a control valve group 25, and a hydraulic motor 26. The plunger pump 24 is respectively connected to the hydraulic motor 26, the pusher hydraulic cylinder 8, the extrusion hydraulic cylinder 13, and the opening hydraulic cylinder 17 through the control valve group 25, and provides power sources for the hydraulic motor 26, the pusher hydraulic cylinder 8, the extrusion hydraulic cylinder 13, and the opening hydraulic cylinder 17 respectively. The output shaft of the hydraulic motor 26 is coaxially fixed with the driving sprocket 11 of the drive mechanism and can drive the driving sprocket 11 to rotate. During specific manufacturing, the oil inlet of the plunger pump 24 is connected to the fuel tank 28, and the oil return pipelines of the pusher hydraulic cylinder 8, the extrusion hydraulic cylinder 13, and the opening hydraulic cylinder 17 are all connected to the fuel tank 28. Among them, the hydraulic motor 26 is controlled by a variable-frequency motor and drives the spiral feeding rod 10 to achieve feeding through chain drive. The maximum bearing pressure designed for the extrusion hydraulic cylinder 13 is 31.5 MPa, and the actual use pressure is 25 MPA. The pressure of the extrusion hydraulic cylinder 13 is controlled by the control valve group 25, which increases the thrust of the extrusion hydraulic cylinder 13. The thickness of the slag cake can reach 40 - 50 mm, greatly improving the working efficiency. The above power unit is all controlled by a controller, which is more intelligent. Compared with traditional motor drive, it has less noise and is more energy-saving.

[0040] Further optimize the above solution. As Figure 2 shown, a liquid level gauge (not shown in the figure) is provided inside the recycling box 2, and a circulation pump 27 that can be linked with the liquid level gauge is provided at the top. The circulation pump 27 transports the cutting oil or cutting fluid in the recycling box 2 to the machine tool for standby through a delivery pipeline (not shown in the figure). When the liquid level in the recycling box 2 reaches the set requirement, the liquid level gauge sends a start signal to the circulation pump 27, and the circulation pump 27 can automatically drain the cutting oil or cutting fluid, which can be recycled for cutting processing, saving the consumption of cutting oil or cutting fluid and reducing production costs.

[0041] When applying the present utility model, the automatic operation mode or the manual operation mode can be selected on the touch screen, and the specific operation process is as follows:

[0042] Put the cutting waste into the first feed hopper 3 and let it fall into the second feed hopper 4. Start the hydraulic motor 26 to drive the spiral feed rod 10 to push the cutting waste in the second feed hopper 4 into the forming inner sleeve 21 of the briquetting die 5; at the same time, start the pusher hydraulic cylinder 8 to drive the push plate 9 to push the cutting waste downward and continue to push it into the second feed hopper 4.

[0043] When the pressure sensor detects that the pressure in the inner cavity of the briquetting die 5 reaches the set pressure, the spiral feed rod 10 rotates reversely for 0.1 second, and the pusher hydraulic cylinder 8 resets.

[0044] Start the extrusion hydraulic cylinder 13 to drive the pusher rod 14 to extrude the cutting waste in the forming inner sleeve 21. When the pressure in the inner cavity reaches the set value, the pressure sensor sends a return signal, and the extrusion hydraulic cylinder 13 drives the pusher rod 14 to reset and wait for the next feeding.

[0045] Repeat the above steps until the pressure in the inner cavity of the briquetting die 5 reaches the set value of 20 MPA, the cutting waste is pressed into a briquette, and the extrusion hydraulic cylinder 13 is depressurized.

[0046] Start the door opening hydraulic cylinder 17 to drive the baffle door plate 18 to lift the baffle door plate 18 to open the door; start the extrusion hydraulic cylinder 13 again to push the slag cake out of the briquetting die 5.

[0047] Then, the door opening hydraulic cylinder 17 resets, drives the baffle door plate 18 to descend to close the door; the extrusion hydraulic cylinder 13 resets and waits for feeding.

[0048] When there is no pressure transmission signal after the equipment runs three times, it is default that there is no material in the feed hopper, and the equipment runs standby (the rotational speed of the frequency conversion motor is 300 revolutions per minute).

[0049] In addition, during the extrusion process of the cutting waste, the cutting oil or cutting fluid in the cutting waste will enter the lower recycling tank. When the liquid level gauge detects the liquid level of the cutting oil or cutting fluid, the circulation pump is automatically started to pump the cutting oil or cutting fluid to the pipeline and transport it to the cold processing machine tool, realizing the recycling of the cutting oil or cutting fluid in the cold processing.

[0050] To sum up, the present utility model has a compact structure, good safety performance, and high working efficiency. It can be docked with the chip conveyor around the machine tool, enabling the cutting waste generated during the reinforcement process to directly enter the first feed hopper, realizing automatic feeding. Then, the cutting waste is sequentially fed into the forming inner sleeve through the spiral feed rod, and after being extruded and formed in the forming inner sleeve by the pusher rod, a high-density slag cake is obtained, achieving the purpose of recycling the cutting waste metal chips of the machine tool, which is more environmentally friendly; the compressed cutting waste can reduce the occupied space, facilitate transportation, and reduce the transportation cost of urban renewable resources.

[0051] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
