Description

Technical Field

[0001] This utility model relates to the field of milling cutter processing technology, specifically to a bar cutting device for milling cutter processing. Background Technology

[0002] A milling cutter is a tool specifically designed for milling operations. It can be used on a milling machine to perform machining operations such as grooves, planes, and steps on workpieces. When using a milling cutter, tungsten carbide rods must first be cut to the required length according to product requirements.

[0003] Among the existing technologies, the patented announcement number CN222095498U discloses a bar cutting device for tungsten carbide milling cutters, which includes: a processing table with a through groove in the middle of the processing table; an L-shaped plate on the transverse moving assembly; an electric cylinder installed on the top inner wall of the L-shaped plate; a connecting box connected to the output end of the electric cylinder; a cutting machine at the bottom of the connecting box; a water spraying mechanism on the inner wall of one end of the L-shaped plate; a metal frame inside the collection box; a filter screen on the metal frame; a cleaning brush on the top of the filter screen; and a driving mechanism for moving the cleaning brush on the collection box.

[0004] In existing technologies, the device is prone to rotation during the cutting of bar stock, and the bar stock is sometimes not in a horizontal position during the fixing process, making continuous cutting impossible. Each cutting operation requires manual fixing. To address this, we propose a bar stock cutting device for milling cutter processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a bar cutting device for milling cutter processing. The bar is not easy to rotate during the cutting process, ensuring that the bar is in a horizontal state after being fixed. The bar can be cut continuously without the need for manual fixing after each cut, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bar cutting device for milling, comprising a mounting table, a moving and anti-rotation component, a movable component, and a bar fixing component;

[0007] Mounting platform: Four support legs are fixedly connected to the four corners of the lower end, and the upper end of the mounting platform is equipped with a moving and anti-rotation component, a movable component and a bar fixing component;

[0008] The moving and anti-rotation assembly includes a dovetail-shaped slide, a mounting frame, a conveyor wheel, a motor, mounting blocks, and a threaded rod. The upper front side of the mounting platform has corresponding dovetail-shaped slides on the left and right sides. The lower left and right sides of the mounting frame are slidably connected to the dovetail-shaped slides. Two mounting blocks are fixedly connected to the upper front part of the mounting platform, and a threaded rod is rotatably connected between the mounting blocks. A motor is fixedly connected to the upper front side of the mounting platform, and the output shaft of the motor is fixedly connected to the threaded rod. The threaded rod is threadedly connected to the lower middle part of the mounting frame. A conveyor wheel is rotatably connected to the lower inner side of the mounting frame. A motor is fixedly connected to the left end of the mounting frame, and the output shaft of the motor is fixedly connected to the conveyor wheel.

[0009] Its core structure includes an installation platform as the basic support platform, which is fixed by four support legs; the moving and anti-rotation components are slidably connected to the installation frame through dovetail grooves, and the installation frame is moved by the second motor driving the second threaded rod. When the bar is short, it is fixed by a fixing device, and then the bar moves by the movement of the installation frame at the same time. When the bar is long, the first motor drives the conveyor wheel to rotate to push the bar; the moving components and the bar fixing components are used to adjust the cutting position and clamp the bar, respectively. The bar is pushed to the cutting station by the conveyor wheel, and the installation frame achieves precise movement through the second threaded rod to ensure accurate bar positioning.

[0010] Furthermore, the moving and anti-rotation assembly also includes a dual-axis motor, a threaded rod, a mounting plate, a sliding clamp, an arc-shaped rubber plate, an L-shaped mounting plate, a spring, and an anti-rotation pin. Two sliding clamps are slidably connected to the left and right ends of the inner side of the mounting frame. An arc-shaped rubber plate is fixedly connected to the inner side of each sliding clamp. Two mounting plates are slidably connected to the left and right ends of the mounting frame. The lower end of each mounting plate is fixedly connected to the sliding clamp. A dual-axis motor is fixedly connected to the middle of the upper end of the mounting frame. A threaded rod is fixedly connected to the output shaft of the dual-axis motor. The threads of the two threaded rods are opposite. The threaded rod is threadedly connected to the upper end of the mounting plate. An L-shaped mounting plate is snapped into the upper left side of the mounting frame. The inner side of the L-shaped mounting plate is slidably connected to the upper end of the anti-rotation pin. A spring is sleeved on the outer side of the anti-rotation pin. Both ends of the spring are fixedly connected to the L-shaped mounting plate and the anti-rotation pin, respectively. The lower outer side of the anti-rotation pin is slidably connected to the mounting frame.

[0011] The moving and anti-rotation assembly further includes a dual-axis motor driving a reverse threaded rod, which causes the sliding clamping block to move the arc-shaped rubber plate to clamp the bar stock. The arc-shaped rubber plate prevents the bar stock from rotating. At the same time, when the bar stock is short, a shallow machining groove is preset on the surface of the bar stock. After cutting, the groove is located in the scrap area. The anti-rotation pin is inserted into the end face of the bar stock under the action of a spring to prevent rotation. The dual-axis motor synchronously drives the threaded rods on both sides to retract, causing the sliding clamping block to clamp the bar stock. The anti-rotation pin presses down to fix the axial direction of the bar stock and prevents the bar stock from rotating.

[0012] Furthermore, the active component includes a mounting plate, a damping rod, a threaded rod three, a threaded cylinder, a gear one, a gear two, a motor three, a hydraulic press mounting bracket, and a hydraulic press. Two hydraulic press mounting brackets are fixedly connected to the upper right side of the mounting platform, one at the front and one at the back. A hydraulic press is mounted on the upper end of each hydraulic press mounting bracket. Two mounting plates are fixedly connected to the upper middle part of the mounting platform, one at the front and one at the back. Two damping rods are fixedly connected to the upper left and right sides of each mounting plate. A threaded cylinder is rotatably connected to the upper middle part of the mounting plate. A threaded rod three is threadedly connected to the inner side of the threaded cylinder. Gear one is fixedly connected to the lower outer end of the threaded cylinder. A motor three is fixedly connected to the lower rear side of the mounting platform. Gear two is fixedly connected to the output shaft of the motor three, and gear two meshes with two gears one.

[0013] The active component drives the three motors, which in turn drive the two gears to mesh with the first gear, causing the threaded cylinder to rotate and the threaded rod to rise and fall. This adjusts the height of the bottom support of the mounting and fixing device, ensuring that the bar is horizontal when it is fixed. The damping rod enhances stability. The three motors drive the two threaded cylinders through the gear set to achieve synchronous lifting and lowering. The hydraulic press clamps and fixes the bar from above, preventing it from tilting during cutting.

[0014] Furthermore, the bar stock fixing assembly includes a mounting base, a sliding block, a bidirectional threaded rod, a replaceable clamping block, and an electromagnetic device. Each hydraulic press has a mounting base fixedly connected to its lower end. The upper end of each threaded rod is rotatably connected to the middle of a mounting base. The upper end of the damping rod is fixedly connected to the left and right ends of the mounting base. A bidirectional threaded rod is rotatably connected to the inner side of the mounting base. Two sliding blocks are slidably connected to the inner side of the mounting base. The sliding blocks are threadedly connected to the bidirectional threaded rod. The lower end of the replaceable clamping block is slidably connected to the upper end of the mounting base. The left and right ends of the replaceable clamping block are rotatably connected to the sliding blocks. An electromagnetic device is embedded in the inner side of the replaceable clamping block.

[0015] The bidirectional threaded rod drives the sliding block to move and fix the replaceable clamping block, which facilitates the replacement of the device. The replaceable clamping block is suitable for bars of different diameters. The electromagnetic device is energized to attract the metal bars and further strengthens the fixation of the bars to prevent them from rotating or moving.

[0016] Furthermore, it also includes a self-locking electric telescopic rod, a rotating wheel mounting frame, a rotating wheel, a motor, a mounting bracket, a telescopic rod, and an arc-shaped plate. The self-locking electric telescopic rod is fixedly connected to the upper rear side of the mounting platform. The rotating wheel mounting frame is snapped into the upper end of the self-locking electric telescopic rod. Multiple rotating wheels are rotatably connected to the inner side of the rotating wheel mounting frame. The motor is fixedly connected to the left end of the rotating wheel mounting frame. The output shaft of the motor is fixedly connected to the rotating wheel. A mounting bracket is fixedly connected between the mounting frame on the upper right side of the mounting platform and the hydraulic press mounting frame. A telescopic rod is fixedly connected to the upper end of the mounting bracket. The lower end of the telescopic rod is hinged to the middle of the upper end of the arc-shaped plate. A level detection device is provided on the inner side of the arc-shaped plate.

[0017] A self-locking electric telescopic rod is added to adjust the height of the rotating wheel mounting frame. The motor drives the rotating wheel to assist in conveying the processed bar stock. The telescopic rod and the arc plate on the mounting frame are calibrated for the position of the bar stock through a level detection device. The arc plate fits against the bar stock to detect and correct the levelness of the bar stock.

[0018] Furthermore, it also includes a cutting device, which is installed between the two hydraulic press mounting frames on the upper right side of the mounting platform. The cutting device, installed between the two hydraulic press mounting frames, cuts the fixed bar stock.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This bar cutting device for milling has the following advantages:

[0020] 1. This bar cutting device for milling cutters starts by activating a dual-axis motor to drive two threaded rods with opposite threads to rotate. This causes the sliding clamps on both sides and the arc-shaped rubber plate to move inward synchronously, clamping the middle of the bar to prevent rotation. Simultaneously, anti-rotation pins can be used for shorter bars. The anti-rotation pins are inserted into a shallow groove on the end face of the bar under the action of a spring to prevent axial rotation. Activating motor three drives gear two to rotate, which in turn drives the two meshing gears one and the threaded cylinder to rotate synchronously, causing threaded rod three to rise and fall. This adjusts the height of the mounting base to ensure that the bar is in a horizontal and stable state, making it less likely to rotate during the bar cutting process and ensuring that the bar is in a horizontal state after being fixed.

[0021] 2. This bar cutting device for milling cutters enables continuous cutting of bar stock without the need for manual fixing after each cut. When using this cutting device, first place the bar stock to be processed on the conveyor wheel inside the mounting frame. Select the conveying mode according to the length of the bar stock: for longer bar stock, start motor one to drive the conveyor wheel to rotate and convey the bar stock forward; for shorter bar stock, drive threaded rod two to rotate through motor two, which drives the mounting frame to move along the dovetail groove as a whole, thereby pushing the bar stock forward. No manual fixing is required after each cut. Attached Figure Description

[0040] The working principle of the bar cutting device for milling cutter processing provided by this utility model is as follows: When using this cutting device, the bar to be processed is first placed on the conveyor wheel 33 inside the mounting frame 32. The conveying mode is selected according to the length of the bar: For longer bars, the motor 34 is started to drive the conveyor wheel 33 to rotate, conveying the bar forward; for shorter bars, the motor 36 drives the threaded rod 315 to rotate, driving the mounting frame 32 to move along the dovetail groove 31 as a whole, thereby pushing the bar forward. After the bar is conveyed to the cutting station, the dual-axis motor 37 is started to drive the two reverse-threaded rods 38 to rotate, driving the sliding clamps 310 on both sides and the arc-shaped rubber plate 311 to move inward synchronously, clamping the middle of the bar to prevent it from rotating.

Insert the bar stock into the shallow groove pre-set on the end face to prevent axial rotation. Then, start the motor 3 47 to drive the gear 2 46 to rotate, which drives the two meshing gears 1 45 and the threaded cylinder 44 to rotate synchronously, causing the threaded rod 3 43 to rise and fall, thereby adjusting the height of the mounting base 51 to ensure that the bar stock is in a horizontal and stable state. Pressure is applied from above by the hydraulic press 49. At the same time, the rotation of the bidirectional threaded rod 53 drives the two sliding blocks 52 to move towards each other, driving the replaceable clamping block 54 to clamp the bar stock. The electromagnetic device 55 is activated to attract and reinforce the bar stock. The cutting device 13 cuts the fixed bar stock. After the cutting is completed, the height of the rotating wheel mounting frame 7 can be adjusted by the self-locking electric telescopic rod 6. The motor 4 9 drives the rotating wheel 8 to assist in conveying the processed bar stock. The arc plate 12 and its internal level detection device can be used to detect and assist in calibrating the position and level of the bar stock.
