Abstract
Description
Technical Field
[0001] This application relates to the field of metal material recycling technology, and in particular to an apparatus for automatically compressing metal cutting chips. Background Technology
[0002] During the processing of metal materials, the continuous relative movement between the workpiece and the cutting tool causes the shearing force on the cutting layer material to exceed its bearing capacity, resulting in shearing and separation from the base material to produce cutting chips.
[0003] In related technologies, the metal material undergoes continuous shearing deformation along the slip surface, the grains are elongated and fibrous, forming a continuous banded structure, and the high temperature generated by friction causes the cutting material to soften and extend further. As the cutting process proceeds, the metal cutting chips are carried out of the cutting area by the cutting fluid or airflow.
[0004] The existing metal cutting chips have the following problems: the centrifugal force generated by the rotation of the workpiece causes the filamentous cutting chips to be thrown to the outside of the workpiece, and after repeated collisions with the tool or workpiece surface, they become entangled. The metal cutting chips eventually become a metal ball. The spherical metal cutting chips are bulky and take up too much space, making them inconvenient for further recycling. Summary of the Invention
[0005] To facilitate further recycling of metal cutting chips, this application provides an apparatus for automatically compressing metal cutting chips.
[0006] The device for automatically compressing metal cutting chips provided in this application adopts the following technical solution:
[0007] An automatic device for compressing metal cutting chips includes: a housing, a feeding mechanism, and a pressing mechanism. The feeding mechanism and the pressing mechanism are both disposed inside the housing. The pressing mechanism includes a cylinder, a first pressing plate, and a second pressing plate. The side of the first pressing plate is fixedly connected to one end of the piston rod of the cylinder. The second pressing plate is arranged in the same direction as the first pressing plate. The cylinder drives the piston rod to move to the feeding outlet of the feeding mechanism, thereby causing the first pressing plate to cooperate with the second pressing plate to compress the metal cutting chips into blocks.
[0008] By adopting the above scheme, the first pressure plate cylinder, in conjunction with the second pressure plate, compresses the metal cutting chips, so that the metal cutting chips are squeezed from loose clumps into high-density, small-volume blocks, reducing subsequent processing costs and facilitating further recycling.
[0009] Preferably, the pressing mechanism further includes a flapper and a second motor. The flapper is horizontally disposed between the first pressing plate and the second pressing plate, and the second motor can drive the flapper to rotate horizontally.
[0010] By adopting the above scheme, the flip plate is responsible for supporting the metal cutting chips to complete the compression process. After the flip plate rotates horizontally, the blocky metal cutting chips fall to the next process.
[0011] Preferably, the chassis is provided with a material trough and a material channel. The material trough is opened on the upper surface of the chassis and is funnel-shaped. One end of the bottom of the material trough is connected to the top of the material channel. The material channel is inclined from top to bottom towards the outside of the chassis. The material channel is located directly below the pressing mechanism. The side wall of the chassis is provided with a discharge port, and the material channel is connected to the discharge port.
[0012] By adopting the above scheme, the inclined trough wall accelerates the flow of metal cutting chips under the action of gravity, reduces the formation of dead material zone, and after the metal cutting chips fall from the pressing mechanism, they slide directly down the material channel and leave the machine box from the discharge port.
[0013] Preferably, the feeding mechanism includes a chain, a first motor, and a screw conveyor. The first motor is located at the bottom of the housing, and the screw conveyor is located at the bottom of the trough. The motor is rotatably connected to the outer shaft of the screw conveyor via the chain.
[0014] By adopting the above scheme, the first motor drives the screw conveyor through the chain. During the rotation of the screw conveyor, the screw conveyor uses its own blades to grab the metal cutting chips falling from the trough and feed them horizontally into the pressing mechanism, which indirectly improves the processing efficiency.
[0015] Preferably, the chassis is further provided with an oil tank, an oil pump and an oil pipe. The oil tank is located directly below the material channel. The material channel has a leakage hole that penetrates the upper and lower surfaces of the material channel. A baffle is provided above the oil tank. The oil pump is located on the baffle. The oil pump is connected to the outside of the chassis through the oil pipe.
[0016] By adopting the above scheme, the cutting fluid is removed while the metal cutting chips are squeezed out. The cutting fluid flows from the surface or side of the feed channel into the oil tank and is pumped out to the outside of the machine for centralized collection and treatment by the action of the oil pump.
[0017] Preferably, the side wall of the chassis is provided with an access door, and the access door is hinged to the side wall of the chassis.
[0018] By adopting the above solution, workers can directly observe and repair the inside of the chassis by opening the inspection door, which is simple and convenient.
[0019] Preferably, an exhaust fan is built into the upper side wall of the chassis, and a hollow structure is provided on the lower side wall of the chassis.
[0020] By adopting the above solution, the high-speed rotation of the exhaust fan blades generates airflow, which causes air exchange between the inside and outside of the chassis, reducing the temperature inside the chassis and reducing the occurrence of overheating in various mechanisms.
[0021] Preferably, the bottom of the chassis is also provided with several metal support feet.
[0022] By adopting the above solution, the impact of vibrations generated by each mechanism during operation on the device is reduced, the device's impact resistance is improved, and the metal support feet provide good load-bearing performance for the chassis.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By compressing metal cutting chips from loose clumps into high-density, small-volume blocks, subsequent processing costs are reduced and further recycling is facilitated.
[0025] 2. Improved the cutting fluid removal rate and collection efficiency of metal cutting chips;
[0026] 3. The device is highly integrated, with all mechanisms arranged in an orderly manner and interconnected, which improves the stability and processing efficiency of the device. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0032] This application discloses an apparatus for automatically compressing metal cutting chips. (Refer to...) Figure 1An automatic compression device for metal cutting chips includes a housing 3, a feeding mechanism 1, and a pressing mechanism 2. The feeding mechanism 1 and the pressing mechanism 2 are both located inside the housing 3. The feeding mechanism 1 is responsible for conveying the metal cutting chip raw material, and the pressing mechanism 2 is connected to the feeding mechanism 1 and is responsible for pressing the metal cutting chip.
[0033] Furthermore, an inspection door 31 is provided on the side wall of the chassis 3. The inspection door 31 is hinged to the side wall of the chassis 3. Workers can directly observe, repair and clean the inside of the chassis 3 by opening the inspection door 31, which is simple and convenient and indirectly improves the safety of the device.
[0034] On the other hand, an exhaust fan 33 is built into the upper side wall of the chassis 3. The fan blades of the exhaust fan 33 generate airflow by rotating at high speed, which causes air exchange between the inside and outside of the chassis 3, reduces the temperature inside the chassis 3, and reduces the occurrence of overheating of various mechanisms. Similarly, the hollow structure 34 opened at the lower side wall of the chassis 3 also plays the same role.
[0035] Meanwhile, in this embodiment, the chassis 3 is rectangular, and a metal support foot 32 is installed at each of the four corners of the bottom of the chassis 3. The metal support foot 32 can effectively reduce the impact of vibration generated by each mechanism during operation on the device and improve the device's impact resistance. In addition, the metal support foot also provides good load-bearing performance for the chassis 3.
[0036] On the other hand, refer to Figure 2 The pressing mechanism 2 includes a cylinder 21, a first pressing plate 22, and a second pressing plate 23. The cylinder 21 is fixed to the inner wall of the housing 3. The piston rod 211 of the cylinder 21 is horizontally oriented towards the front side of the housing 3. The first pressing plate 22 is vertically fixed to the end of the piston rod 211 of the cylinder 21. The second pressing plate 23 is fixed to the top inner wall of the housing 3 and is arranged in the same direction as the first pressing plate 22.
[0037] Furthermore, the cylinder 21 drives the piston rod 211 to move to the feeding outlet of the feeding mechanism 1, which in turn drives the first pressure plate 22 to push a clump of metal cutting chips toward the second pressure plate 23. The first pressure plate 22 and the second pressure plate 23 apply pressure to the clump of metal cutting chips, causing the metal cutting chips to shrink and deform inward, reducing the volume and internal voids of the metal cutting chips.
[0038] Specifically, the metal cutting chips are compressed from loose clumps into high-density blocks, which not only efficiently removes residual cutting fluid from the metal cutting chips, but also reduces the contact area with air, thereby lowering the oxidation rate of the metal cutting chips.
[0039] Furthermore, when transporting the same mass of metal cutting chips, a smaller volume can hold more material, reducing logistics and transportation costs and facilitating the further recycling of metal cutting chips.
[0040] On the other hand, the pressing mechanism 2 also includes a flap 24 and a second motor 25. The second motor 25 is located on the rear inner wall of the housing 3. The flap 24 is horizontally arranged between the first pressing plate 22 and the second pressing plate 23 and is fixed to the end of the output shaft of the second motor 25. The flap 24 is located below the discharge position of the feeding mechanism 1 and is horizontally arranged in the initial state to support the metal cutting chips during the pressing process.
[0041] Furthermore, the second motor 25 can drive the flap 24 to rotate. After the metal cutting chips are squeezed out, the piston rod 211 of the cylinder 21 drives the first pressure plate 22 to reset. The second motor 25 drives the flap 24 to rotate horizontally by 90°. Without the support of the flap 24, the blocky metal cutting chips fall to the next process.
[0042] On the other hand, the chassis 3 is provided with a material trough 35 and a material channel 36. The material trough 35 is located on the upper surface of the chassis 3 and is funnel-shaped. Therefore, the inclined sidewall of the material trough 35 accelerates the flow of metal cutting chips by gravity, reducing the occurrence of material accumulation and dead material zones.
[0043] Meanwhile, one end of the bottom of the material trough 35 is connected to the top of the material channel 36. The material channel 36 is inclined from top to bottom towards the outside of the machine housing 3. The material channel 36 is located directly below the flip plate 24. The side wall of the machine housing 3 has a discharge port. The material channel 36 and the discharge port are connected to each other. The block-shaped metal cutting chips fall from the pressing mechanism 2 onto the upper surface of the material channel 36, then slide down along the inclined material channel 36, and leave the machine housing 3 from the discharge port, and are collected and recycled.
[0044] On the other hand, the feeding mechanism 1 includes a chain 12, a first motor 11 and a screw conveyor 13. The first motor 11 is located at the bottom of the housing 3, and the screw conveyor 13 is horizontally located at the bottom of the trough 35. The first motor 11 is rotatably connected to the outer shaft of the screw conveyor 13 through the chain 12.
[0045] Specifically, the working principle of the screw conveyor 13 is based on the mechanical thrust generated by the rotation of the screw blades, which works in conjunction with the weight of the material itself and the frictional resistance to realize the transportation of the material along the screw axis.
[0046] Therefore, when the first motor 11 drives the screw conveyor 13 to rotate via the chain 12, the screw conveyor uses its spiral blades to grab the metal cutting chips falling from the trough 35 and feeds them into the pressing mechanism 2 in the horizontal direction, which indirectly improves the processing efficiency. The large spacing between the spiral blades can also effectively reduce the occurrence of metal cutting chip jamming.
[0047] On the other side, refer to Figure 3The chassis 3 is also equipped with an oil tank 37, an oil pump 38 and an oil pipe 39. The oil tank 37 is located directly below the material channel 36. The material channel 36 is provided with a drain hole 361, which penetrates the upper and lower surfaces of the material channel 36. Therefore, the cutting fluid is removed while the metal cutting chips are squeezed, and the cutting fluid can flow directly into the oil tank 37 along the surface or side of the material channel 36.
[0048] Meanwhile, a baffle is installed above the oil tank 37, and the oil pump 38 is installed on the baffle. The oil pump 38 is connected to the outside of the oil tank 37 and the casing 3 through the oil pipe 39. The working principle of the oil pump 38 is to change the pump chamber volume through mechanical movement to realize the suction, pressurization and transportation of oil.
[0049] Specifically, when the plunger of the oil pump 38 reciprocates in the pump chamber and moves outward, the volume of the pump chamber increases to form a negative pressure. The oil pipe 39 draws in the cutting fluid flowing into the oil tank 37. When the plunger compresses inward, the volume decreases, and the oil is pressurized and discharged along the oil pipe 39 to the outside of the machine casing 3, where it is collected and processed.
[0050] The implementation principle of the automatic compression device for metal cutting chips in this application embodiment is as follows: with the cooperation of the feeding mechanism 1 and the pressing mechanism 2, the metal cutting chips achieve a batch and efficient compression process, compressing the loose and lumpy metal cutting chips into a high-density, small-volume block metal cutting chip aggregate, while removing the residual cutting fluid in the metal cutting chips, reducing the subsequent transportation and anti-fouling costs, and facilitating further recycling.
[0051] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
