Description

All of them are designed size data input and processed by the milling cutter on the surface of the workpiece in the longitudinal and transverse directions; and the milling cutter will generate a large amount of cutting chips when processing the workpiece. Although there are also debris collection devices on existing milling machines, the collection effect is not satisfactory. Some small debris will be retained on the machine tool. On the one hand, small debris is prone to rust, which will cause the rust degree of mechanical parts where the debris is retained to increase. On the other hand, the accumulation of debris mixed with the lubricating oil on the machine tool will be integrated into hard bumps, which will cause movement obstruction in the running position, which will accelerate the shortening of the service life of the milling machine and cannot meet the continuous processing needs.

[0015] The present invention also includes a method for using a gantry milling machine with a chip cleaning mechanism, and the specific steps of use are as follows: S1. Send the required raw materials to the production line, and carry out necessary inspection and quality control. Then, send the preheated steel to the cold drawing machine. Cold drawing is to draw the steel through multiple sets of dies of the cold drawing machine continuously to achieve the required size and shape. During the cold drawing process, the steel will undergo multiple drawing and cooling to improve the strength and hardness of the material. Fix the standard workpieces of rails, I-shaped steels, and mouth-shaped steels in the clamping frame position. According to the size of the workpiece to be processed, the adjustment signal is input into the main machine to control the gantry mechanism to drive the milling cutter body to perform milling and forming work on the workpiece to be processed; S2. The cutting chips generated by the milling cutter body when cutting the workpiece randomly fall to the top of the processing table. During the operation of the milling cutter body, the blower fan synchronously works at the air gathering cavity to generate accelerated airflow, which generates an upward buoyancy at the top opening of the slide groove to prevent it from falling into the slide groove, thus preventing most of the cutting chips from falling into the slide groove; S3. The accelerated airflow in the gas gathering cavity will also generate a tendency accelerated airflow through the guide air holes not blocked by the clamping frame, pushing part of the cutting chips to the residue collection mechanism for centralized collection; S4. Due to the obstruction of the main table to the accelerated airflow, the accelerated airflow forms a longitudinal guide and a lateral reverse rebound, so that its airflow and the accelerated airflow continuously transported from the processing table direction collide at the position of the residue collection mechanism, forming an airflow disturbance at the top of the collection bucket frame, causing the cutting chips to "settle to" the collection bucket frame position.

[0016] Technical effects and advantages of the present invention: The present invention cooperates with the blower fan by slotting and opening the processing table. When the blower fan works, the diffuser hole generates a longitudinal accelerated airflow, and the guide hole generates an accelerated airflow tending to the residue collection mechanism, so that the cutting chips and thread-shaped cutting chips suspended on the top of the processing table are pushed to the residue collection mechanism for centralized collection. The generated accelerated airflow can not only take the cutting chips away from the processing table, but also effectively prevent the formation of rust spots, effectively reduce the occurrence of accelerated rust of the milling machine due to the formation of rust spots, thereby extending the service life of the milling machine. The smooth discharge of cutting chips can effectively solve the problem of the formation of hard convex points caused by the cutting chips entering the sliding groove, and avoid the situation that the clamping frame cannot move smoothly at the processing table position due to the formation of hard convex points. The present invention sets the platform higher than the processing platform, and the main platform blocks the accelerated airflow so that the accelerated airflow forms longitudinal guidance and lateral reverse rebound, so that the airflow and the accelerated airflow continuously transported from the processing platform direction continuously move horizontally to the platform higher than the residue collection mechanism, and block it horizontally. The airflow blocking forms a folded airflow, which is similar to the air conditioner blowing horizontally to the wall and then turning the wind direction back. The turned wind flow and the accelerated wind flow that continues to blow are in opposite directions to form a counter-attack, forming an airflow disturbance at the top of the collection bucket frame, and prompting the cutting chips to "settle" to the collection bucket frame position; the accelerated airflow generated by the diffuser holes and the guide air holes can accelerate the air flow at the processing platform position, so that the temperature of the workpiece part increased due to milling is taken away by the accelerated airflow, thereby cooling the periphery of the milling machine during operation; The present invention uses a gantry mechanism in coordination with a milling cutter body and adds a second pressure sensor and a first pressure sensor, which can respectively perform fault-tolerant processing due to abnormal data entry in the horizontal and vertical positions, thereby avoiding excessive processing due to errors in accidentally entered data, thereby causing damage to the gantry mechanism or the milling cutter body, or motor burning caused by it, and further ensuring the service life of the milling machine.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention provides Figure 1-13A gantry milling machine with a chip purification mechanism is shown, comprising a processing table 1 and a workpiece 2 arranged on the top of the processing table 1, a frame 3 with a height greater than that of the processing table 1 is fixedly provided on both sides of the processing table 1, a plurality of blowers 4 are evenly fixedly provided on the top of one side of the frame 3, a residue collection mechanism 5 is provided between the frame 3 and the processing table 1 on the other side, and a movable clamping frame 6 for fixing and supporting the workpiece 2 is also provided on the top of the processing table 1, a gantry frame mechanism 7 is fixedly provided between the tops of the two frames 3, and a milling cutter body 8 is movably provided on the gantry frame mechanism 7; Furthermore, in order to further improve the purpose of discharging the cutting chips generated at the position of the processing table 1, the processing table 1 includes a table plate body 101, and the table plate body 101 is transversely provided with a plurality of non-through gas gathering cavities 102, and the gas gathering cavities 102 are arranged corresponding to the air outlets of the blower fans 4 arranged at the position of the stand 3, and a plurality of sliding grooves 103 are evenly arranged longitudinally on the top of the table plate body 101 for adjusting the relative position of the clamping frame 6 on the processing table 1, and air diffusion holes 104 are arranged between the air gathering cavities 102 and the sliding grooves 103 for connecting the spaces between the air gathering cavities 102 and the sliding grooves 103, and guide air holes 105 are arranged between the air gathering cavities 102 and the top surface of the table plate body 101, and the guide air holes 105 are arranged in an inclined hole shape for guiding the accelerated airflow blown out of the air diffusion holes 104; Furthermore, in order to ensure the normal position of the processing table 1 for processing the workpiece 2 and to accelerate the airflow supply, an air inlet 302 is provided on the top of the platform 3 away from the residue collection mechanism 5. The air inlet 302 is arranged in alignment with the blower fan 4. A connecting port 303 is provided at the connection between the side wall of the platform 3 and the air gathering cavity 102. The air inlet 302 and the connecting port 303 are combined to form a connected air duct.

[0033] Specifically, a workpiece 2 of a certain specification, such as a rail, a section steel, or a mouth steel, is fixed on the position of the clamping frame 6, and the workpiece 2 is milled by the milling cutter body 8. The chips generated by the cutting randomly fall to the top position of the processing table 1 (because different positions will produce chips of different thicknesses). Some of the chips are in the shape of curled threads, and because their size is larger than the width of the top opening of the slide groove 103, they cannot fall into the slide groove 103, while the micro-chips fall into the slide groove 103. During the operation of the milling cutter body 8, the blower fan 4 works synchronously to blow accelerated airflow into the corresponding air gathering cavity 102 position through the air duct formed by the air inlet 302 and the connecting port 303. The accelerated airflow is respectively generated by the diffuser holes 104 that are not blocked by the clamping frame 6 to generate longitudinal accelerated airflow, and an upward buoyancy is generated at the top opening of the slide groove 103, which is opposite to the self-weight force of the chips falling from this position. Because the weight of the cutting chips is relatively low, the upward high-speed airflow prevents them from falling into the slide groove 103, which can effectively prevent most of the cutting debris from falling into the slide groove 103 under milling, and the accelerated airflow in the gas gathering cavity 102 will also generate an accelerated airflow inclined to the residue collection mechanism 5 through the guide air hole 105 not blocked by the clamping frame 6, and generate an inclined airflow on the top of the processing table 1, wherein part of the cutting chips will be pushed to the residue collection mechanism 5 for centralized collection along with the lateral accelerated airflow, and part of the cutting chips that are not directly blown to the position of the residue collection mechanism 5 will not fall into the slide groove 103, but will gradually approach the position of the residue collection mechanism 5 along with the uninterrupted lateral accelerated airflow until they are stored, so that the cutting chips generated can be discharged from the processing table 1 at any time during the milling process; Among them, the accelerated airflow generated by the blower fan 4 arranged on the frame 3 can not only take the cutting chips away from the processing table 1, but also avoid the formation of rust spots due to oxidation caused by the accumulation of cutting chips in the air. The curled shape of the cutting chips will increase the contact area with the air, thereby causing rust. Since the rust (the main body of the milling machine is made of steel) is loose and porous, water molecules and oxygen molecules can continue to penetrate into it until it is completely corroded; if the rust is not handled in time, the rust will absorb more water, so that the iron inside will continue to undergo oxidation reaction, accelerating the rust of iron products. Corrosion rate; therefore, discharging the cutting chips generated by milling away from the processing table 1 can effectively prevent the formation of rust spots, effectively reduce the occurrence of accelerated rust of the milling machine due to the formation of rust spots, thereby extending the service life of the milling machine. In addition, due to the formation of rust spots, mixed lubricating oil and incompletely corroded cutting chips are prone to form hard protrusions. The smooth discharge of cutting chips by the milling machine can effectively solve the problem of the formation of hard protrusions caused by the cutting chips entering the sliding groove 103, and avoid the situation where the clamping frame 6 cannot move smoothly on the processing table 1 due to its formation.

[0034] Furthermore, the stands 3 on both sides include a main platform 301, and a plurality of fixing blocks 304 are fixedly provided on both sides of the bottom of the main platform 301. Through holes are provided on the fixing blocks 304, and the stand 3 is fixed to the ground using bolts and gaskets to fix the position of the entire milling machine. The blower fan 4 is connected to the main platform 301 by bolts, and the accelerated airflow generated by the blower fan 4 is blown into the corresponding air gathering cavity 102 through a continuous air duct formed between the air inlet 302 and the connecting port 303. The accelerated airflow in the air gathering cavity 102 is respectively generated as a longitudinal airflow by the diffuser holes 104 and formed as a deflected airflow through the guidance of the guide air holes 105; The deflected airflow generated at the guide air hole 105 disturbs the longitudinal airflow generated by the diffuse air hole 104, forming an airflow deflected toward the residue collection mechanism 5, and taking away the cutting chips on the top of the processing table 1; The residue collection mechanism 5 includes a collecting bucket frame 501 for collecting cutting chips, wherein the height of the collecting bucket frame 501 is lower than the height of the platform 3, the longitudinal cross section of the collecting bucket frame 501 is set to be funnel-shaped, and a transmission motor 502 is fixedly provided on the outer side of the collecting bucket frame 501; A conveyor belt 503 is provided inside the collecting bucket frame 501. The output shaft of the transmission motor 502 cooperates with the bearing to drive the conveyor belt 503. An air suction type elevator 504 is tilted and fixed at one end of the collecting bucket frame 501 to absorb the cutting chips transported by the conveyor belt 503 and discharge them from the discharge port. The frame 3 is fixed to the ground through the through holes on the fixing block 304 by bolts and gaskets to fix the position of the whole milling machine. The main table 301 is higher than the height of the processing table 1, which can block the lateral moving cutting chips, so that the cutting chips fall to the collecting bucket frame 501, and are transported by the conveyor belt 503 driven by the transmission motor 502 to transport the collected cutting chips to the feeding port at the bottom end of the air suction elevator 504. Then, as the air suction elevator 504 lifts them, they are discharged from the outlet in a centralized manner. The user can set a collection box / trolley at the outlet of the air suction elevator 504 to collect them in a centralized manner for reuse. During this period, the accelerated airflow is blocked by the main table 301, so that the accelerated airflow forms a longitudinal guide and a lateral reverse rebound, so that the airflow and the accelerated airflow continuously transported from the processing table 1 are collided at the position of the residue collection mechanism 5, and an airflow disturbance is formed on the top of the collection bucket frame 501, which makes the cutting chips "settled" to the position of the collection bucket frame 501; in addition, the accelerated airflow generated by the diffuser holes 104 and the guide air holes 105 can accelerate the air flow at the processing table 1, so that the temperature of the workpiece 2 increased due to milling is taken away by the accelerated airflow, thereby cooling the surrounding area of ​​the milling machine during operation; The clamping frame 6 includes a placing frame 601, and two movable limit blocks 602 are arranged on the top of the placing frame 601.
