Description
Technical Field
[0001] This invention relates to the field of engine technology, specifically to a wire rod processing mold production equipment and its usage method. Background Technology
[0002] The engine stator is the stationary component of the engine. It consists of a frame, iron core, windings, copper rings, and a base screw. The frame is the structural component that fixes the iron core. The iron core and windings are the essential electromagnetic parts of the stator for generating a rotating magnetic field and ensuring the path of magnetic flux and current. The windings are composed of many wire bars arranged in a certain pattern. The wire bars are usually embedded in slots in the iron core in two layers and connected to form a circuit in a certain wiring method. After the current is collected through the copper ring leads, the electrical power is output. Due to electrical and thermal reasons, the wire rod needs to be attached to the slot of the iron core along its entire length with minimal gaps. Since the engine rotor needs to rotate, the cavity accommodating the rotor is also cylindrical. To reduce the heat generated by eddy currents on the wire rod during installation, it is spirally extended along the inner wall of the cavity to the other side and connected to the power source. The general processing method is to open a slot of appropriate shape on the inner wall of the cavity and then insert the wire rod into the slot to complete the installation. However, since the wire rod and the slot spirally extend to the other side on the inner wall of the cavity, and there needs to be an angle difference between the two openings of the wire rod, the spiral processing angle of the wire rod is required to be high. Generally, hot pressing is used to shape the straight wire rod. This method requires high precision of the hot pressing mold, especially when preparing wire rods with different rotation angles and sizes, which requires the use of different high-precision hot pressing molds.
[0003] Therefore, a new technical solution is needed to address the above problems. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a wire rod processing mold production equipment and its usage method.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a wire rod processing mold production equipment and its method of use, comprising a three-axis milling machine and a milling cutter, wherein the milling cutter is mounted on the spindle of the three-axis milling machine, and a milling cutter support frame including an upper connecting part and a lower connecting part is provided on the spindle support frame of the three-axis milling machine, wherein the upper connecting part is fixedly connected to the support frame of the spindle of the three-axis milling machine, and the lower connecting part is connected to the secondary cutting edge position at the end of the milling cutter, and the upper connecting part and the lower connecting part slide relative to each other along the extension direction of the milling cutter and are fixed by bolts, wherein two clamping devices are detachably connected to the processing table of the three-axis milling machine, wherein the clamping devices include clamping elements, and the clamping elements on the two clamping devices face each other and rotate along the same horizontal line.
[0006] By adopting the above technical solution, a three-axis milling machine is first used to drive the milling cutter to move on a horizontal plane, then the end of the milling cutter is supported by a milling cutter support frame, and then the clamping device is used to drive the workpiece to rotate along a horizontal line as an axis, thereby machining a spiral curved surface on the side wall where the workpiece intersects with the horizontal plane and increasing the machining accuracy.
[0007] The invention is further configured such that: the clamping device includes a servo motor, a fixed frame, and a gearbox; the servo motor is fixedly connected to the fixed frame and powered by the gearbox on the fixed frame; a rotating shaft powered by the gearbox is rotatably connected to the fixed frame; the clamping member includes a support plate fixedly connected to the other end of the rotating shaft; a plurality of vertically extending pressing grooves are provided at the end away from the rotating shaft; a plurality of pressure plates are slidably connected to the pressing grooves; and the upper and lower pressure plates are connected by locking bolts.
[0008] By adopting the above technical solution, two plates to be processed into a mold are joined together and placed on the two lower pressure plates. The locking bolts are rotated and the upper pressure plate is driven to press against the upper surface of the plates, thereby clamping the plates using the pressure plate components. The fixing frame is fixed on the worktable of the three-axis milling machine. Then, the servo motor is started, and the servo motor drives the rotating shaft to rotate through the gearbox. The rotating shaft drives the support plate to rotate, and the support plate drives the two plates to rotate through the pressure plate. The servo motor is electrically connected to the three-axis milling machine and is controlled by the program of the three-axis milling machine.
[0009] The invention is further configured such that: the upper connecting part includes a "7"-shaped upper connecting block, one end of which points horizontally towards the support frame of the main shaft, and the other end points vertically downward; a downwardly extending sliding groove is provided on the side wall of a lower section of the upper connecting block, and an upper through groove passes through the inner wall of the sliding groove; the lower connecting part includes a "7"-shaped lower connecting block, one end of which points horizontally towards the milling cutter on the main shaft, and the other end points vertically upward; the vertical section of the lower connecting block is slidably connected to the inner wall of the sliding groove; and a lower through groove communicating with the upper through groove passes through the side wall of the vertical section of the lower connecting block; the upper connecting block and the lower connecting block are detachably connected and controlled by bolts passing through the through groove and the lower through groove; and a connecting sleeve that engages with the secondary cutting edge at the end of the milling cutter is rotatably connected to the upper end of the lower section of the lower connecting block.
[0010] By adopting the above technical solution, the structure of the upper section of the lower connecting block slidingly connected to the inner wall of the sliding groove is utilized. The lower connecting block is manually pushed up and down to control the height of the lower section of the connecting sleeve, and the connecting sleeve is placed on the lower end surface of the milling cutter to complete the engagement between the lower end of the milling cutter and the inner wall of the connecting sleeve. Then, bolts are passed through the lower through groove and the upper through groove and tightened to complete the fixed connection between the lower connecting block and the upper connecting block. The connecting sleeve is rotatably connected to the surface of the lower connecting block, so that when the milling cutter rotates, it not only provides support at the lower end of the milling cutter but also does not hinder the rotation of the milling cutter, thereby increasing the cutting effect.
[0011] The invention is further configured as follows: Step 1, loosen the bolts connecting the upper and lower connecting blocks and slide the lower connecting block downwards to the lowest point; Step 2, place the assembled lower and upper molds on the clamping device, rotate the locking bolts to clamp the lower and upper molds, start the servo motor and control the rotation shaft, support plate and pressure plate to rotate around the rotation shaft axis through the gearbox, thereby controlling the upper ends of the lower and upper molds to be parallel to the horizontal plane; Step 3, install a normal-sized milling cutter on the spindle of a three-axis milling machine, start the three-axis milling machine and drive the normal-sized milling cutter to rotate, and then drive the milling cutter to move linearly downwards through the three-axis milling machine to mill through holes in the lower and upper molds; Step 4, stop the rotation of the spindle of the three-axis milling machine and move it to a position above the lower and upper molds, then replace the milling cutter with a vertical cutting milling cutter, adjust the height of the spindle and the milling cutter and make the vertical cutting milling cutter penetrate into the holes in the lower and upper molds and protrude from the other side, then move the lower connecting block and make the connecting sleeve on the lower connecting block... Step 5: Engage the end mill with the lower end of the end mill, and then tighten the bolts connecting the lower and upper connecting blocks; Step 6: While keeping the end mill from contacting the lower and upper dies, start the spindle of the three-axis milling machine and drive the end mill to rotate. Use the main cutting edge of the end mill to cut the lower and upper dies. The servo motor is electrically connected to the three-axis milling machine, and the program on the three-axis milling machine controls the rotation angle of the lower and upper dies to machine the mold cavity; Step 7: Loosen the bolts connecting the lower and upper connecting blocks, separate the engagement between the connecting sleeve and the lower end of the end mill, start the three-axis milling machine and drive the end mill to move out of the mold cavity, and then machine the space on the lower and upper dies that accommodates the second and first wires; Step 8: Fix the lower die on the two side support plates and align the positions of the second and third wires. Use bolts to fix the side support plates and the lower die, connect the upper die to the upper connecting piece, and open a threaded hole at the upper end of the side support plate.
[0012] By adopting the above technical solution, a through hole is first made in the assembled plate using a normal-sized milling cutter. Then, the end mill is replaced and passed through the through hole in the plate. The milling cutter support is adjusted so that the connecting sleeve is fitted onto the lower end of the end mill from below the plate. The three-axis milling machine is started and the plate is cut using the side wall of the end mill. At the same time, the servo motor is also controlled by the program on the three-axis milling machine. By combining the rotation of the plate and the movement of the end mill on the horizontal plane, a curved surface is formed on the inner wall of the plate. The one-time processing method not only meets the curvature requirements of adapting to the inclination of the wire rod, but also increases the fit between the two molds, further increasing the mold accuracy and reducing production costs.
[0013] The present invention is further configured such that: the mold includes an upper mold, a lower mold, and two side support plates, the upper mold and the lower mold are located between the two side support plates, and the lower mold is connected to the side support plates and forms a mold cavity with the upper mold, and the mold cavity extends and is inclined along the line connecting the two side support plates; a heating tube is provided between the two side support plates, the heating tube includes a plurality of resistance heaters and eddy current heaters, the plurality of resistance heaters are evenly arranged on the upper mold and the lower mold near the mold cavity, the eddy current heater surrounds the mold cavity and the resistance heaters on the outer ring, and the eddy current heater includes a second wire located on the lower mold and a first wire located on the upper mold.
[0014] By adopting the above technical solution and utilizing the separate structure of the side support plate, lower mold, and upper mold, during processing, the inner wall of the mold cavity between the upper and lower molds, which have curved surfaces, is processed first. Then, the side support plate and lower mold, which are difficult to process, are connected as one unit, and the upper connecting piece is connected as one unit. This not only reduces the processing difficulty but also ensures the surface accuracy of the mold and increases product quality. The mold is then heated by heat transfer using a resistance heater on the mold. Furthermore, the detachable connection between the side support plate and lower mold, and the detachable connection between the upper mold and upper connecting piece, allows for the replacement of the lower and upper molds, further reducing production costs.
[0015] The present invention is further configured such that the cutting edge length of the end mill is greater than the depth of the holes in the lower die and the upper die.
[0016] By adopting the above technical solution, the side edge of the end mill is used to process the sheet metal, thereby forming the upper and lower molds.
[0017] The present invention is further configured such that step five involves gradually reducing the feed rate while repeating the cycle multiple times.
[0018] By adopting the above technical solution and utilizing the principles of machining, the machining accuracy of the upper and lower mold surfaces is further increased through rough machining followed by fine machining, while also enhancing the surface finish of the curved surfaces.
[0019] In summary, the present invention has the following beneficial effects: The hot pressing mold is disassembled into a side support plate, a lower mold, and an upper mold. A milling cutter is then used to cut holes in the sheet-like lower and upper molds. The mold cavity is then machined using the side edge of an end mill that passes through the holes. A three-axis milling machine is used to control the movement of the milling cutter on the horizontal plane, and a clamping device is used to rotate the sheet metal of the lower and upper molds along the horizontal line to machine the curved surface of the mold cavity. This not only reduces the production cost of high-precision molds, but also allows for the production of wire rods of different specifications by changing the lower and upper molds, further reducing production costs.
[0020] Heating is achieved by using a resistance heater for heat conduction, and then by using an eddy current heater to directly heat the wire rod inside the mold cavity, thereby further increasing the heating effect of the wire rod.
[0021] By utilizing the detachable connection between the lower mold and the side support plate, and the detachable connection between the upper connector and the upper mold, the production cost of the mold can be further reduced according to the different specifications of the wire rod.

[0026] like Figures 1 to 10As shown, in step one, loosen the bolts connecting the upper connecting block 29 and the lower connecting block 30 and slide the lower connecting block 30 downwards to the lowest point; in step two, place the assembled lower mold 12 and upper mold 19 on the clamping device 23, and rotate the locking bolt 27 to clamp the lower mold 12 and upper mold 19, start the servo motor 35 and control the rotating shaft 37, support plate 25 and pressure plate 26 to rotate around the axis of the rotating shaft 37 through the gearbox, thereby controlling the upper ends of the lower mold 12 and upper mold 19 to be parallel to the horizontal plane; in step three, install a normal-sized milling cutter on the spindle of the three-axis milling machine 22, start the three-axis milling machine 22 and drive the normal-sized milling cutter to rotate, and then drive the milling cutter to move linearly downwards through the three-axis milling machine 22 to mill through the lower mold 12 and upper mold 19. Step 4: Stop the rotation of the spindle of the three-axis milling machine 22 and move it to a position above the lower die 12 and the upper die 19. Then change the milling cutter to a vertical cutting milling cutter, adjust the height of the spindle and the milling cutter and make the vertical cutting milling cutter penetrate into the holes of the lower die 12 and the upper die 19 and protrude from the other side. Then move the lower connecting block 30 and make the connecting sleeve 31 on the lower connecting block 30 engage with the lower end of the vertical cutting cutter.

Step 5: Start the spindle of the three-axis milling machine 22 and drive the vertical cutting cutter to rotate while keeping the vertical cutting cutter out of contact with the lower die 12 and the upper die 19. Use the main cutting edge of the vertical cutting cutter to cut the lower die 12 and the upper die 19.

The program-controlled servo motor 35 on the three-axis milling machine 22 drives the lower mold 12 and the upper mold 19 to rotate and machine the mold cavity 15; Step six, loosen the bolts connecting the lower connecting block 30 and the upper connecting block 29, and separate the connecting sleeve 31 from the lower end of the milling cutter. Then start the three-axis milling machine 22 and drive the end mill to move out of the mold cavity 15. Then machine the space on the lower mold 12 and the upper mold 19 that accommodates the second wire 16 and the first wire 17; Step seven, fix the lower mold 12 on the two side support plates 11 and align the positions of the second wire 16 and the third wire 18. Use bolts to fix the side support plates 11 and the lower mold 12. Connect the upper mold 19 to the upper connecting piece 13 and open a threaded hole at the upper end of the side support plate 11. 21; The mold includes an upper mold 19, a lower mold 12, and two side support plates 11.

[0027] The lower mold 12 and upper mold 19, which are in the shape of sheet metal to be processed, are assembled together and placed on the lower pressure plate 26. Then, the locking bolt 27 is rotated, which moves the upper pressure plate 26 downward and presses the assembled sheet metal together. The thickness of the sheet metal is the same as the width of the wire rod. Then, a milling cutter is installed on the spindle of the three-axis milling machine 22, and a through hole is made in the assembled sheet metal using the milling cutter to increase the flatness of the hole sidewall. At the same time, the diameter of the hole is made larger than the diameter of the milling cutter. Then, the spindle rotation is stopped, and the upper end mill is replaced. The bolts connecting the lower connecting block 30 and the upper connecting block 29 are loosened. The lower connecting block 30 is manually pushed upward and the connecting sleeve 31 is placed on the outer side of the lower end of the end mill. Then, the bolts are tightened to fix the lower connecting block 30 and the upper connecting block 29. The connecting sleeve 31 is rotatably connected to the lower connecting block 30.

The second wire 16 and the first wire 17... The technical conductive wires on conductor 17 are recessed inward and electrically connected to the protrusions, thereby forming an eddy current heater. The heat resistance temperature of the insulating material is greater than the maximum temperature during mold heating. Several resistance heaters are provided along the direction of the mold cavity 15 in the lower mold 12 and the upper mold 19. These resistance heaters are metal objects with high resistance, and their exposed positions do not contact the lower mold 12 and the upper mold 19. The wire rod to be shaped is placed in the space between the lower mold 12 and the side support plate 11. Then, the upper connector 13 and the upper mold 19 are placed downward from the side support plate 11, with the upper mold 19 positioned directly above and corresponding to the lower mold 12. At the same time, the wire rod is clamped, causing the wire rod to undergo elastic deformation and adapt to the shape of the mold cavity 15. Finally, the locking screw 14 is screwed into the threaded hole 21 from the through hole 20 at the upper end of the upper connector 13.The upper mold 19, side support plate 11, and lower mold 12 are then connected. The eddy current heater and resistance heater are then energized and heated, and the shape of the wire rod is changed using thermoforming.
