Description

Technical Field

[0001] The present application relates to the technical field of steel processing, and in particular to a milling device for steel processing. Background Art

[0002] In the steel processing process, milling is a commonly used processing method. Milling refers to the use of a rotating multi-edged tool to cut the workpiece. It is a highly efficient processing method. During the milling process, the tool cuts the workpiece and needs to rotate at high speed to grind the cut surface of the workpiece flat. The tool and the workpiece will generate a lot of heat due to friction. In order to prevent the tool and workpiece from being damaged by milling, generally during the milling process, coolant is continuously sprayed on the tool and workpiece to cool them down. Therefore, after a milling process, a lot of waste chips and waste liquid will accumulate on the workbench, which not only affects the cleanliness of the working environment, but also makes it difficult for the operator to clean up.

[0003] A Chinese patent with announcement number CN217194184U discloses a milling processing device for ultra-high strength corrosion-resistant steel structural parts, including a support frame, a milling head is rotatably connected to the inner wall of the support frame, a cooling hose is provided on the inner wall of the support frame, a stabilizing clamp is provided on the inner wall of the support frame, a controller is fixedly connected to one side of the support frame, a collecting device is provided on the inner wall of the support frame, the collecting device includes a rotating rod and a collecting box, the collecting box is clamped to the inner wall of the support frame, the rotating rod is rotatably connected to the inner wall of the support frame, a clamping block is fixedly connected to the side of the collection box, and the clamping block is clamped to the inner wall of the support frame.

[0004] The above-mentioned steel structure milling processing device only collects the waste chips and waste water generated during the milling process by opening a chip drop groove, so that the waste chips and waste water can fall freely into the collection box through the chip drop groove. The waste chips and waste liquid on the workbench table need to be manually scraped and pushed into the chip drop groove and fall into the collection box by the operator, which not only increases the workload of the operator and reduces the work efficiency; at the same time, the sharp waste chips and the waste liquid may contain ingredients that corrode the skin, which can easily cause the operator to be injured during the cleaning process, making it difficult to ensure the safety of the operator during the work. Utility Model Content

[0005] In order to improve the collection efficiency of waste chips and waste liquid in milling operations, the present application provides a milling device for steel processing.

[0006] The present application provides a milling device for steel processing that adopts the following technical solution:

[0007] A milling device for processing steel comprises a workbench, a circle of baffles is provided on the top of the workbench near the periphery, a support frame is provided on the workbench, a milling cutter is rotatably provided in the support frame, and a driving mechanism is provided on the support frame corresponding to the movement of the milling cutter, a liquid outlet pipe for spraying coolant to the milling cutter is provided on one side of the milling cutter, and a fixing part for fixing the workpiece is also provided on the workbench, a cavity is provided under the table top of the workbench, a collection box for collecting waste chips and waste liquid is provided in the cavity, a chip trough is provided vertically on the table top of the workbench, the chip trough is connected to the collection box, and a chip pushing component is also provided on the table top of the workbench for pushing waste chips and waste liquid on the table top to the chip trough.

[0008] By adopting the above technical solution, the operator first fixes the workpiece on the work surface through the fixing parts, and then drives the milling cutter to rotate and work, and moves the milling cutter to the vicinity of the end face of the workpiece through the driving mechanism to perform milling operations on the workpiece. During the milling operation between the milling cutter and the workpiece, the nozzle of the liquid outlet pipe is always aligned with the milling cutter, and the tool and workpiece being milled are continuously sprayed with coolant to cool down. After the milling operation is completed, due to the enclosure of the baffle, most of the waste chips and waste liquid remain on the work surface, and some of the waste chips and waste liquid fall into the collection box through the chip chute. The waste chips and waste liquid on the table that do not fall into the collection box are eventually pushed to the chip chute by the chip pushing assembly and all fall into the collection box. The collection of waste chips and waste liquid does not require the operator to manually clean the work surface, thereby reducing the possibility of the operator being injured during the cleaning process and improving the collection efficiency of waste chips and waste liquid during milling operations.

[0009] Optionally, the chip pusher assembly includes a mounting plate slidably set on the workbench, a chip pusher plate connected to the mounting plate, and a driving member that drives the mounting plate to slide. The mounting plate is set on the side of the workbench away from the chip drop groove, and the inner walls of the two baffles perpendicular to the length direction of the mounting plate are provided with limiting grooves along the sliding direction of the mounting plate. A slider is slidably set in each of the limiting grooves, and the sliders are correspondingly set at both ends of the mounting plate.

[0010] By adopting the above technical solution, the mounting plate is guided and limited by the limiting groove, so that the mounting plate slides on the work surface and drives the chip pusher plate to slide back and forth along the length direction perpendicular to the chip groove. When the mounting plate drives the chip pusher plate to slide in the direction close to the chip groove, the chip pusher plate will push and scrape the waste chip mixture that falls onto the work surface to the chip groove, and the waste chip mixture will all fall into the collection box through the chip groove, thereby improving the recovery rate of the waste chip and coolant mixture.

[0011] Optionally, the driving component includes a screw rod that passes through the mounting plate on the workbench through threaded rotation, and a driving motor that drives the screw rod to rotate, and the axial direction of the screw rod is arranged parallel to the length direction of the limiting groove.

[0012] By adopting the above technical solution, the drive motor is driven to work, and the output shaft of the drive motor rotates to drive the screw rod to rotate. Since the mounting plate and the screw rod are matched through threaded rotation and are limited by the guide of the limiting groove, when the screw rod rotates, the mounting plate slides back and forth along the guide of the limiting groove.

[0013] Optionally, the mounting plate is arranged at an angle, and when the mounting plate is in an initial state, the top side wall of the mounting plate contacts the inner side wall of the baffle.

[0014] By adopting the above technical solution, the mounting plate is initially tilted. When waste chips generated during the milling process fall onto the mounting plate, they slide to the side of the mounting plate away from the inner sidewall of the baffle as the mounting plate tilts. As the mounting plate slides, the waste chips are pushed to the chip chute, where they fall into the collection box. This reduces the possibility of waste and chip mixtures accumulating at the edge of the workbench.

[0015] Optionally, a brush is provided on one side of the chip pusher plate close to the chip drop groove, and the brush is arranged to contact the table surface of the workbench.

[0016] By adopting the above technical solution, when the mounting plate slides toward the chip trough, the brush first pushes and sweeps the larger waste chips and most of the coolant toward the chip trough, while the chip pusher plate pushes and scrapes the remaining small waste chips and coolant toward the chip trough. The coordinated use of the brush and the chip pusher plate helps to push the waste chip mixture that falls into the chip guide trough to the chip trough as much as possible and into the collection box, thereby improving the recovery rate of the waste chip and coolant mixture.

[0017] Optionally, the fixing part includes a plurality of limit blocks and two plug-in rods arranged at the bottom of each limit block. A plurality of groups of plug-in holes are vertically opened on the table top of the workbench. Each of the plug-in holes is connected to the collection box. Each group of the plug-in holes corresponds to the two plug-in rods at the bottom of each limit block, and the plug-in rods are plugged into and matched with the plug-in holes.

[0018] By employing this technical solution, the insertion rods and the insertion holes engage, allowing the plurality of stoppers to surround the workpiece and secure it. During the milling process, the waste mixture promptly falls through the insertion holes into a collection box below the workbench, reducing the likelihood of waste mixture accumulating around the workpiece during milling and minimizing its impact on the milling process.

[0019] Optionally, a filter frame is detachably provided in the horizontal direction inside the collection box, and a pull ring is provided on the top of the filter frame for the operator to carry the filter frame.

[0020] By adopting the above technical solution, the setting of the filter frame helps to automatically separate the waste chips and waste liquid from the waste chip mixture falling from the chip drop trough, and the setting of the pull ring makes it easy for the operator to take the waste chips out of the collection box, which is convenient for subsequent classification and recycling.

[0021] Optionally, a plurality of universal positioning wheels are provided at the bottom of the collection box, and a handle for pushing the collection box to move is also provided on the collection box.

[0022] By adopting the above technical solution, the setting of the universal positioning wheel makes it easy for the operator to pull out and push the collection box easily through the handle, and the universal positioning wheel also has a locking function, making it easy for the operator to recycle the waste mixture collected in the collection box in time.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The operator first fixes the workpiece on the work surface through the fixing parts, and then drives the milling cutter to rotate and work, and moves the milling cutter to the vicinity of the end face of the workpiece through the driving mechanism to perform milling operations on the workpiece. During the milling operation between the milling cutter and the workpiece, the nozzle of the liquid outlet pipe is always aimed at the milling cutter, and the tool and workpiece being milled are continuously sprayed with coolant to cool down. After the milling operation is completed, due to the enclosure of the baffle, most of the waste chips and waste liquid remain on the work surface, and some of the waste chips and waste liquid fall into the collection box through the chip chute. The waste chips and waste liquid on the table that do not fall into the collection box are eventually pushed to the chip chute by the chip pushing assembly and all fall into the collection box. The collection of waste chips and waste liquid does not require the operator to manually clean the work surface, thereby reducing the possibility of the operator being injured during the cleaning process and improving the collection efficiency of waste chips and waste liquid in milling operations;

[0025] 2. The mounting plate is guided and limited by the limiting groove, so that the mounting plate slides on the work surface and drives the chip pusher to slide back and forth in the length direction perpendicular to the chip chute. When the mounting plate drives the chip pusher to slide in the direction close to the chip chute, the chip pusher pushes and scrapes the waste chip mixture that falls on the work surface to the chip chute. The waste chip mixture falls into the collection box through the chip chute, thereby improving the recovery rate of the waste chip and coolant mixture.

[0026] 3. Drive the drive motor to work, and the output shaft of the drive motor rotates to drive the screw to rotate. Since the mounting plate and the screw are matched through threaded rotation and are limited by the guide of the limiting groove, when the screw rotates, the mounting plate slides back and forth along the guide of the limiting groove.
