Description

Technical Field

[0001] The utility model belongs to the technical field of band saw blade processing, in particular to a vertical band saw blade gear milling machine. Background Art

[0002] A band saw blade milling machine is a device specifically designed to manufacture or repair band saw blades. This machine produces or reprocesses the blade by cutting teeth of specific shapes and specifications. A band saw blade milling machine uses one or more rotating cutter heads with carbide inserts to precisely cut the desired tooth profile at high speeds. These tooth profiles can be customized to suit different application requirements, such as varying the angle and shape of the teeth for cutting different materials, such as wood and metal.

[0003] Horizontal band saw blade gear milling machines are currently widely used in the industry. These machines use a vertical clamping system for the workpiece (band saw blade) (with the high-speed steel wire on the teeth facing upward). The back of the band saw blade is positioned on a horizontal shim, and multiple blades are stacked and fed into a hydraulic clamping vise. The machine head, equipped with a milling cutter, is mounted on a slide that rests on a horizontal guide rail. The machine head is fed horizontally via a servo motor and ball screw. After machining is complete, the cutter is lifted vertically and retracted horizontally. The hydraulic vise is released, and the feed mechanism pulls the band saw blade to the new machining position. A hydraulic triangular iron flattening device flattens the stacked band saw blades, clamping the hydraulic vise. The feed vise returns to its origin, and the tool and machine head begin a new machining cycle. A deburring plate, used to eliminate milling burrs, is mounted vertically within the hydraulic vise and is typically pushed by a servo push rod mechanism mounted in the lower chamber of the horizontal workbench.

[0004] However, during use, it was discovered that this horizontal feed method resulted in a large amount of iron chips accumulating near the jaws. When the band saw blades were loosened and flattened, the chips entered between adjacent blades, creating gaps between the blades after they were clamped. This, in turn, caused burrs to form after the blades were milled. Furthermore, the existing deburring plates were structurally limited and were relatively short. During automated cycle processing, frequent machine downtime due to deburring plates running out wasted processing time and reduced production capacity. Utility Model Content

[0005] The purpose of the present utility model is to provide a vertical band saw blade gear milling machine in response to the above-mentioned technical problems. This gear milling machine moves the cutting tool from bottom to top when milling the band saw blade, and the band saw blade is placed horizontally and stacked vertically. Iron chips are not easy to enter between adjacent band saw blades. In addition, the width of the band saw blade clamping can be adjusted to adapt to the processing of band saw blades of different widths.

[0006] In view of this, the utility model provides a vertical band saw blade gear milling machine, comprising:

[0007] a base, wherein a clamp base is provided on the base;

[0008] The main clamping tongs are arranged on the clamp base and are used to clamp or release the band saw blade;

[0009] The column mechanism is arranged on the base;

[0010] The milling head box is arranged on the column mechanism, and the milling head box can perform vertical feed motion on the column mechanism. The milling head box is provided with a milling cutter, and the milling head box can drive the milling cutter to rotate and perform milling processing on the band saw blade;

[0011] The translation mechanism is used to drive the milling head box horizontally towards or away from the band saw blade.

[0012] In this technical solution, multiple band saw blades are stacked and passed through the clamping main pliers, which clamp the band saw blades. Then the milling head box moves on the column mechanism to a position below the lowest band saw blade, and the translation mechanism drives the column mechanism and the milling head box to approach the band saw blade, and the milling head box column mechanism is stopped in a suitable position and locked according to the depth of milling on the band saw blade as required. Then the milling head box drives the milling cutter to rotate, and the milling head box is fed vertically upward on the column mechanism to perform vertical milling on all the band saw blades. After milling is completed, the milling head box is reset downward on the column mechanism, and the clamping main pliers releases the band saw blades. After the band saw blade is transported forward a certain distance, the clamping main pliers clamps it again, and the milling head box is fed and reset to complete the second milling. This is repeated to completely mill all the band saw blades.

[0013] In the above technical solution, it further includes a pulling mechanism, a feeding guide mechanism, and a discharging guide mechanism. The pulling mechanism is located in the discharging direction of the clamping main pliers, and is used to pull the milled band saw blade a certain distance in the discharging direction. The feeding guide mechanism is located in the feeding direction of the clamping main pliers, and is used to guide the feeding of the band saw blade; the discharging guide mechanism is located in the discharging direction of the clamping main pliers, and is used to guide the discharging of the band saw blade.

[0014] In the above technical solution, it further includes a horizontal pressing mechanism, which is installed on the milling head box. The horizontal pressing mechanism can move horizontally relative to the milling head box so that the front end of the band saw blade can be pressed before the main clamp is clamped to clamp the band saw blade.

[0015] In the above technical solution, further, it also includes a width adjustment mechanism, which is used to adjust the horizontal position of the clamping main clamp on the clamp base.

[0016] In the above technical solution, further, it also includes a burr plate and a plate clamping mechanism. The burr plate passes through the clamping main clamp and partially protrudes from the clamping main clamp. The plate clamping mechanism is used to push the burr plate toward the milling cutter.

[0017] In the above technical solution, further, it also includes an angle adjustment mechanism, which is arranged between the base and the column mechanism, and the angle adjustment mechanism can adjust the angle between the milling cutter and the band saw blade.

[0018] In the above technical solution, further, it also includes an oil pan, which is arranged under the base and is used to recover the cutting fluid used in the milling process.

[0019] The beneficial effects of the utility model are:

[0020] 1. By stacking multiple band saw blades horizontally and designing the milling cutter's path to feed vertically from bottom to top, it is not easy for iron chips to enter between adjacent band saw blades, reducing the generation of burrs after band saw blade milling.

[0021] 2. By setting up the coordination of the pulling mechanism, the feeding guide mechanism and the discharging guide mechanism, automatic feeding can be realized, which reduces the labor intensity of workers and improves the processing efficiency.

[0022] 3. By setting up a horizontal pressing mechanism, after multiple band saw blades are fed into the clamping main pliers, the horizontal pressing mechanism can first press the front ends of the multiple band saw blades into alignment, and then clamp these band saw blades through the clamping main pliers, ensuring the accuracy of band saw blade processing.

[0023] 4. By setting up a width adjustment mechanism, the position of the clamping main pliers on the clamp base can be adjusted, so that when the rear end of the band saw blades of different widths contacts the clamping main pliers, the front end of the band saw blade can be ensured to be located at the processing position of the milling cutter, thereby improving the applicability of the gear milling machine.

[0024] 5. By setting up the plate clamping mechanism and the burr plate, a longer burr plate can be used during milling, and the burr plate can be pushed forward a distance through the plate clamping mechanism before each milling, which can reduce the frequency of stopping to replace the burr plate.

[0025] 6. By setting up an angle adjustment mechanism, the horizontal angle between the milling cutter and the band saw blade can be adjusted, so that teeth of different angles can be milled on the band saw blade as needed, thereby improving the applicability of the gear milling machine.

[0026] 7. An oil pan is set under the base to recycle the used cutting fluid, so that the cutting fluid can be recycled and the cost of use is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

The clamping lifting mechanism drives the upper clamping pliers to descend and cooperate with the lower clamping pliers to clamp the band saw blade. The clamping lifting mechanism drives the upper clamping pliers to rise to release the band saw blade.

[0044] Angle adjustment mechanism 13: Please refer to Figure 3 and Figure 4The angle adjustment mechanism 13 is located between the base 1 and the column mechanism 4. The angle adjustment mechanism 13 includes a rotary base 1301, a column base 1302, a rotary shaft, a screw rod 1303, a bracket, a scale 1304, a guide rail, a bearing, etc. The column mechanism 4 is arranged on the column base 1302, and the milling head box 5 is installed on the column mechanism 4. The worker manually rotates the screw rod 1303 to make the column base 1302 rotate a certain angle relative to the rotary base 1301. The column mechanism 4 and the milling head box 5 also rotate a certain angle with the column base 1302, thereby adjusting the angle between the milling cutter and the band saw blade.

[0045] Column mechanism 4: please refer to Figure 3 The column mechanism 4 is arranged on the base 1. The column mechanism 4 includes a column box, a Z-axis servo motor, a feed hydraulic cylinder, a guide rail, etc. The column box can move horizontally on the column base 1302, and the milling head box 5 is installed on the guide rail and can perform vertical feed movement along the guide rail. The translation mechanism 6 includes a Y-axis servo motor, a bottom cylinder, and a locking cylinder. The Y-axis servo motor is mainly used to drive the column box and the milling head box 5 to move horizontally to the specified position, so as to determine the milling depth. When the column box moves to the appropriate position, the locking cylinder clamps the column box at the current position. The bottom cylinder is used to reset the column box horizontally. The feed hydraulic cylinder cooperates with the Z-axis servo motor to provide feed power to the milling head box 5 and control the feed speed.

[0046] Milling head box 5: The milling head box 5 includes a spindle motor 15, a spindle, a milling cutter, a cutter holder, and a transmission mechanism. The milling head box 5 is the core part of the gear milling machine. The spindle motor 15 drives the spindle to rotate through a coupling and a transmission mechanism, thereby rotating the milling cutter to perform milling.

[0047] Horizontal pressing mechanism: The horizontal pressing mechanism is installed on the milling head box 5 and is located above the milling cutter; the horizontal pressing mechanism includes a pressure plate, a wedge, and a pressing hydraulic cylinder. The pressing hydraulic cylinder pushes the wedge downward to make the pressure plate extend out of the milling head box 5 in the horizontal direction. Before clamping the main clamp 3 to clamp the band saw blade, the front end of the stacked band saw blades is flattened by the pressure plate extending out of the milling head box 5, and then the pressing hydraulic cylinder pulls the wedge upward to retract the pressure plate into the milling head box 5.

[0048] Feed guide mechanism 7: The feed guide mechanism 7 is installed on the clamp base 2 and is located in the feed direction of the clamping main clamp 3. The feed guide mechanism 7 includes a bracket, a guide wheel, a roller shaft, etc. The feed guide mechanism 7 is mainly used to guide the feeding of the band saw blade to be milled.

[0049] Discharge guiding mechanism 8: The discharge guiding mechanism 8 is installed on the clamp base 2 and is located in the discharge direction of the clamping main clamp 3. The discharge guiding mechanism 8 includes a bracket, a guide wheel, a roller shaft, etc. The discharge guiding mechanism 8 is mainly used to guide the discharge of the milling band saw blade.

[0050] Pulling mechanism 9: The pulling mechanism 9 is installed on the clamp base 2 and is located in the discharge direction of the clamping main clamp 3. The pulling mechanism 9 includes a mounting seat, an upper pulling clamp, a lower pulling clamp, a pulling lifting mechanism, a horizontal drive mechanism, etc. The upper pulling clamp, the lower pulling clamp, and the pulling lifting mechanism are all arranged on the mounting seat. The lower pulling clamp is flush with the upper surface of the lower clamping clamp. The pulling lifting mechanism can drive the upper pulling clamp to move vertically, and the horizontal drive mechanism can drive the mounting seat to move vertically at the discharge of the band saw blade. When the milling cutter completes milling of a position of the band saw blade, the main clamp 3 is clamped to release the band saw blade, and the upper and lower pulling clamps cooperate to clamp the band saw blade. Then the horizontal drive mechanism drives the mounting seat to move a certain distance in the discharge direction of the band saw blade, so that the band saw blade will be pulled forward for a certain distance, so that the unmilled part is relative to the milling cutter position. At this time, the upper and lower pulling clamps release the band saw blade, and the main clamp 3 is clamped to clamp the band saw blade for the next milling process.

[0051] Width adjustment mechanism 10: Please refer to Figure 6 The width adjustment mechanism 10 is located at the inner lower position of the positioning clamp. The width adjustment mechanism 10 includes a dovetail plate, a backing plate, an adjustment mechanism, a locking mechanism, a dial indicator, etc. A dovetail groove is provided on the positioning clamp. The dovetail plate is slidably connected in the dovetail groove. The backing plate is provided at the front end of the dovetail plate. The backing plate can be extended into the front side of the positioning clamp and contact the rear end of the band saw blade. The adjustment mechanism is provided on the positioning clamp and the dovetail plate. The adjustment mechanism can adjust the horizontal position of the dovetail plate on the positioning clamp by converting rotational motion into linear motion, and then adjust the distance between the rear end of the band saw blade and the positioning clamp to achieve adaptation to band saw blades of different widths. The dial indicator is used for fine-tuning.

[0052] Burr plate 11: The burr plate 11 passes through the clamping main clamp 3 and partially protrudes from the clamping main clamp 3. The burr plate 11 is located above the topmost band saw blade in the stacked band saw blades. The principle of using the burr plate 11 is: when multiple saw blades are stacked and milled, burrs will form on the last milled band saw blade, which needs to be taken out separately and repaired manually. In order to improve processing efficiency, a layer of burr plate 11 is generally laid behind the last milled band saw blade. The burr plate 11 is consumed during the milling process of the band saw blade, thereby reducing and eliminating burrs on the band saw blade;

[0053] Plate clamping mechanism 12: The plate clamping mechanism 12 is installed on the clamp base 2. The plate clamping mechanism 12 includes a mounting plate, a screw 1303, a stepper motor, a reducer, a nut bracket, a guide rod, etc. The stepper motor drives the screw 1303 through the reducer to push the nut bracket to move forward on the guide rod. The burr plate 11 is arranged on the nut bracket, and thus moves forward under the push of the nut bracket; the burr plate 11 needs to be pushed forward once before each milling process, and different specifications of milling cutters require corresponding burr plates 11 of different widths, and the width of the burr plate 11 should be slightly longer than the maximum diameter of the milling cutter.

[0054] Oil pan 14: The oil pan 14 is located at the bottom of the machine tool and is used to recover and concentrate the cutting fluid used in the milling process so that the cutting fluid can be recycled.

[0055] The operating steps of the gear milling machine in this embodiment are as follows:

[0056] 1. Prepare for startup, lubricate the rails, and ensure that there is sufficient hydraulic oil and cutting fluid in the hydraulic oil tank.

[0058] 3. Test cutting: Place the parts to be processed into the pulling mechanism 9 and the clamping main clamp 3, test two cuts and test them, and fine-tune the setting parameters or mechanical positions according to the test results until the processed parts meet the requirements.

[0059] 4. Normal processing steps:

[0060] a) Pulling: The upper and lower pulling clamps of the pulling mechanism 9 cooperate to clamp the workpiece and pull it forward for a processing length, while the burr plate 11 is sent forward for a distance;

[0061] b) Clamping: Driven by the Y-axis servo motor, the column box and the milling head box 5 move forward to the specified position and are clamped by the cylinder. The pressure plate on the milling head box 5 extends under the action of the pressing hydraulic cylinder to press the band saw blade flat (horizontally); the upper clamp moves downward under the action of the clamping lifting mechanism to clamp the band saw blade; then the pressing hydraulic cylinder is released, and the pressure plate retreats; at the same time, the upper and lower material pulling clamps are released, and the upper material pulling clamp moves to the initial position;

[0062] c) Milling: The spindle motor 15 is started, the milling cutter rotates, and the milling head box 5 is fed from bottom to top to perform milling processing under the push of the feed hydraulic cylinder. The feed speed is controlled by the Z-axis servo motor;

[0063] d) The column box retracts: the locking cylinder that clamps the column box is released, and the column box is pulled back to the starting position under the action of the bottom cylinder, and the milling head box 5 descends; at the same time, the upper clamp is released;

[0064] e) Repeat steps a) to d) until all the teeth of the band saw blade are milled.

[0065] 5. Clean the site and place the finished materials in the designated location.
