Abstract
Description
Technical Field
[0001] This utility model relates to a device for processing waste materials from die castings and removing splines from die castings, and more particularly to the structure of the device for removing splines from die castings. Background Technology
[0002] In the manufacturing of magnesium alloy steering wheel die-casting parts, cast iron splines, as inserts, need to be pre-formed in a mold before die-casting to obtain the finished product. Due to production processes and technical limitations, a significant number of scrapped steering wheel die-casting parts are generated. To save on raw material costs, these scrapped parts and splines need to be recycled for reuse. Because there is no dedicated workbench, the current method for recycling scrapped parts typically involves manually cutting them with a saw to remove the splines.
[0003] However, this manual sawing method is labor-intensive, time-consuming, and inefficient. Manually cutting each scrapped steering wheel die-cast part takes 5-8 minutes, resulting in high labor costs. Furthermore, manual sawing lacks precision, easily causing overcutting, deformation, and burrs on the cut surface, affecting the reusability of the splines. Additionally, manual sawing generates dust and flying debris, posing safety hazards and occupational health risks to workers.
[0004] The purpose of this invention is to solve the problems of low efficiency, poor accuracy, and easy injury to workers when processing scrapped steering wheel die-cast parts using existing methods. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a device for removing splines from die-cast parts, comprising a vertical saw 1, a positioning device 2, a rotating device 3, and a clamping device 4. The vertical saw 1 has an operating table 11 and a saw blade 12 on its right side, and a kerf 111 extending in the left-right direction to accommodate the saw blade 12 is provided on the left side of the operating table 11. The saw blade 12 is vertically oriented and can move in the left-right direction along the kerf 111. The positioning device 2 includes a slide rail 21, a slider 22, and a translational hydraulic cylinder 23.
[0006] The slide rail 21 is horizontally mounted on the operating table 11, located to the right of the cut 111, and extends in the left-right direction. The left end of the slide rail 21 extends to near the right end of the cut 111. The slider 22 is slidably mounted on the slide rail 21. The translation cylinder 23 is mounted on the operating table 11 and extends in the left-right direction. One end is located at the right end of the slide rail 21, and the other end is connected to the slider 22. It is used to drive the slider 22 to slide in the left-right direction along the slide rail 21. The rotating device 3 is mounted on the slider 22 and is used to drive the clamping device 4 to rotate. The clamping device 4 is mounted on the rotating device 3 and is used to clamp the die-casting part.
[0007] In use, the steering wheel die-casting is fixed on the clamping device. The translation cylinder 23 extends and pushes the slider 22 to move to the left side of the slide rail 21, close to the saw blade 12. The vertical saw 1 controls the saw blade 12 to move to the right, cutting one side of the steering wheel die-casting. The vertical saw 1 controls the saw blade 12 to move to the right, and the rotating device 3 controls the clamping device 4 to rotate 180 degrees so that the other side of the steering wheel die-casting faces the saw blade 12. Then, the vertical saw 1 controls the saw blade 12 to move to the right, cutting the other side of the steering wheel die-casting, and the spline in the steering wheel die-casting can be removed.
[0008] This invention utilizes a vertical sawing machine 1 with an operating table 11, a positioning device 2 on the operating table 11, a rotating device 3 mounted on a slider 22, and a clamping device 4 mounted on the device to fix the steering wheel die-casting. When a scrapped steering wheel die-casting is needed, it is fixed to the clamping device, and a translation cylinder 23 extends to push the slider 22 along the slide rail 21 to the left end of the slide rail 21. This allows the vertical sawing machine 1 to precisely cut the steering wheel die-casting. The rotating device 3 controls the rotation of the steering wheel die-casting, thereby cutting both sides of the steering wheel die-casting and quickly removing the splines from it. This invention eliminates the need for manual operation during the sawing process of the steering wheel die-casting, preventing injury to workers. This invention solves the problems of low efficiency, poor precision, and the risk of worker injury associated with existing methods for processing scrapped steering wheel die-castings.
[0009] Preferably, the rotating device 3 includes a housing 31, a rotating motor 32, and a rotating rod 33. The housing 31 is fixedly mounted on the slider 22. The rotating motor is located on the right side inside the housing 31, with the rotating shaft of the rotating motor 32 facing upwards. A drive gear 321 is provided at the upper end of the rotating shaft. The rotating rod 33 is rotatably mounted on the left side inside the housing 31, with its lower end rotatably connected to the bottom plate of the housing 31 and its upper end extending above the housing 31. A driven gear 331 that meshes with the drive gear 321 is provided on the rotating shaft. A clamping device 4 is located at the upper end of the rotating rod 33.
[0010] The rotating device 3 includes a housing 31, a rotating motor 32, and a rotating rod 33. The rotating rod 33 is rotatably mounted inside the housing 31, with its upper end extending above the housing 31. The rotating motor 32 drives the rotating rod 33 to rotate, which in turn drives the holding device mounted on the upper end of the rotating rod 33 to rotate, thereby allowing the saw blade 12 to saw the steering wheel die-casting from different angles.
[0011] Preferably, the clamping device 4 includes a mounting plate 41 and two clamping cylinders 43. The mounting plate 41 is horizontally disposed on the top of the rotating rod 33, and mounting rods 42 are disposed opposite each other on both sides of the mounting plate 41. One end of the mounting rod 42 is fixedly connected to the mounting plate 41, and the other end extends in a direction away from the mounting plate 41. The two clamping cylinders 43 are respectively disposed on the two mounting rods 42. One end of the clamping cylinder 43 is fixedly disposed on the end of the mounting rod 42 away from the mounting plate 41 by a mounting block 431, and the other end of the clamping cylinder 43 extends in a direction towards the mounting plate 41, and the other end is provided with an electric gripper 44.
[0012] The clamping device 4 includes a mounting plate 41 and two clamping cylinders 43. Mounting rods 42 are set on both sides of the mounting plate 41, and the two clamping cylinders 43 are set on the mounting rods 42. Electric grippers 44 are set at the ends of the clamping cylinders 43. The electric grippers 44 can clamp and fix the steering wheel die casting. After the steering wheel die casting is cut by the saw blade 12, the two clamping cylinders 43 can retract to separate the steering wheel die casting into two parts, thereby quickly removing the spline.
[0013] Preferably, a limiting block 24 is provided at the left end of the slide rail 21. By providing the limiting block 24 at the left end of the slide rail 21, the position of the scrapped steering wheel die-cast part can be more precise, thereby improving the sawing accuracy.
[0014] Preferably, the mounting plate 41 is provided with a limiting ring 45 for accommodating splines. By providing a limiting ring 45 for accommodating splines on the mounting plate 41, when sawing the die-cast steering wheel part that is about to be scrapped, the splines on the die-cast steering wheel part can be inserted into the limiting ring 45, which can fix the scrapped die-cast steering wheel part in a more precise and secure position, thereby improving the sawing accuracy.
[0015] Preferably, it also includes a controller 13, which is connected to the vertical saw 1, the translation cylinder 23, the rotary motor 32, the clamping cylinder 43 and the electric gripper 44 respectively, to control the automatic operation of the equipment. Attached Figure Description

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the equipment for removing splines from die-cast parts includes a vertical saw 1, a positioning device 2, a rotating device 3, a clamping device 4, and a controller 13.
[0025] The vertical saw 1 has an operating table 11 and a saw blade 12 on the right side, and a kerf 111 extending in the left and right direction to accommodate the saw blade 12 on the left side of the operating table 11. The saw blade 12 is vertically arranged and can move in the left and right direction along the kerf 111 to saw the steering wheel die-casting fixed on the clamping device 4.
[0026] The vertical saw 1 is existing technology, and its detailed structure and working principle will not be described in detail here.
[0027] The positioning device 2 includes a slide rail 21, a slider 22, and a translation cylinder 23.
[0028] The slide rail 21 is horizontally set on the operating table 11, located on the right side of the cut 111, and extends in the left and right direction. The left end of the slide rail 21 extends to near the right end of the cut 111, and a limit block 24 is provided on the left end of the slide rail 21.
[0029] By setting a limiting block 24 at the left end of the slide rail 21, the position of the scrapped steering wheel die casting can be more precise when the positioning device 2 moves the steering wheel die casting, thereby improving the sawing accuracy.
[0030] The slider 22 is slidably mounted on the slide rail 21.
[0031] The translation cylinder 23 is mounted on the operating table 11 and extends in the left and right direction. The cylinder body of the translation cylinder 23 is located at the right end of the slide rail 21 and is fixedly connected to the operating table 11. The piston rod of the translation cylinder 23 is connected to the slider 22. The extension and retraction of the piston rod of the translation cylinder 23 can drive the slider 22 to slide in the left and right direction along the slide rail 21.
[0032] like Figure 1 and Figure 4 As shown, the rotating device 3 is mounted on the slider 22 and is used to drive the clamping device 4 to rotate. The rotating device 3 includes a housing 31, a rotating motor 32, and a rotating rod 33. The housing 31 is fixedly mounted on the slider 22.
[0033] The rotating motor 32 is located on the right side inside the housing 31. The rotating shaft of the rotating motor 32 faces upward. The upper end of the rotating shaft is provided with a drive gear 321. The rotating rod 33 is rotatably located on the left side inside the housing 31. The lower end is rotatably connected to the bottom plate of the housing 31, and the upper end extends to the top of the housing 31. The rotating shaft is provided with a driven gear 331 that meshes with the drive gear 321. The clamping device 4 is located at the upper end of the rotating rod 33.
[0034] The rotating device 3 includes a housing 31, a rotating motor 32, and a rotating rod 33. The rotating rod 33 is rotatably mounted inside the housing 31, with its upper end extending above the housing 31. The rotating motor 32 drives the rotating rod 33 to rotate, which in turn drives the holding device mounted on the upper end of the rotating rod 33 to rotate, thereby allowing the saw blade 12 to saw the steering wheel die-casting from different angles.
[0035] like Figure 2 and Figure 5 As shown, the clamping device 4 is mounted on the rotating device 3 and is used to clamp the die-cast part. The clamping device 4 includes a mounting plate 41 and two clamping cylinders 43.
[0036] Mounting plate 41 is horizontally positioned on top of rotating rod 33, and mounting rods 42 are positioned opposite each other on both sides of mounting plate 41.
[0037] One end of the mounting rod 42 is fixedly connected to the mounting plate 41, and the other end extends away from the mounting plate 41.
[0038] Two clamping cylinders 43 are respectively mounted on two mounting rods 42. One end of the clamping cylinder 43 is fixedly mounted on the end of the mounting rod 42 away from the mounting plate 41 by a mounting block 431. The other end of the clamping cylinder 43 extends toward the mounting plate 41 and is equipped with an electric gripper 44.
[0039] The clamping device 4 includes a mounting plate 41 and two clamping cylinders 43. Mounting rods 42 are respectively set on both sides of the mounting plate 41, and the two clamping cylinders 43 are set on the mounting rods 42. Electric grippers 44 are set at the ends of the clamping cylinders 43. The electric grippers 44 can clamp and fix the steering wheel die casting. After the steering wheel die casting is cut by the saw blade 12, the two clamping cylinders 43 can retract to separate the steering wheel die casting into two parts, thereby quickly removing the spline.
[0040] The mounting plate 41 is provided with a limiting ring 45 for accommodating splines. By providing a limiting ring 45 for accommodating splines on the mounting plate 41, when sawing a die-cast steering wheel that is about to be scrapped, the splines on the die-cast steering wheel can be inserted into the limiting ring 45, which can fix the scrapped die-cast steering wheel more accurately and firmly, thereby improving the sawing accuracy.
[0041] The controller 13 is connected to the vertical saw 1, the translation cylinder 23, the rotary motor 32, the clamping cylinder 43, and the electric gripper 44 respectively, and controls the automatic operation of the equipment.
[0042] like Figure 6 As shown, in use, the lower end of the spline on the steering wheel die-casting 5 is inserted into the fixing ring. The controller 13 controls the electric gripper of the clamping device to clamp and fix the steering wheel die-casting 5. The controller also controls the translation cylinder 23 to extend and push the slider 22 along the slide rail 21 to the left end of the slide rail 21, bringing the steering wheel die-casting 5 closer to the saw blade 12. The vertical saw 1 controls the saw blade 12 to move to the right, cutting one side of the steering wheel die-casting 5. The vertical saw 1 then controls the saw blade 12 to move to the right, and the rotating device 3 controls the clamping device 4 to rotate 180 degrees, so that the other side of the steering wheel die-casting 5 faces the saw blade 12. The vertical saw 1 continues to control the saw blade 12 to move to the right, cutting the other side of the steering wheel die-casting 5. The piston rods of the two clamping cylinders 43 are then controlled to retract, separating the cut steering wheel die-casting 5, allowing the spline in the steering wheel die-casting 5 to be removed.
[0043] This invention utilizes a vertical sawing machine 1 with an operating table 11, a positioning device 2 on the operating table 11, a rotating device 3 mounted on a slider 22, and a clamping device 4 mounted on the device to fix the steering wheel die-casting. When a steering wheel die-casting is to be scrapped, it is fixed to the clamping device, and a translation cylinder 23 extends to push the slider 22 along the slide rail 21 to the left end of the slide rail 21. This allows the vertical sawing machine 1 to precisely cut the steering wheel die-casting. The rotating device 3 controls the rotation of the steering wheel die-casting, thereby cutting both sides of the steering wheel die-casting and quickly removing the splines from the steering wheel die-casting. This invention eliminates the need for manual operation during the sawing process of steering wheel die-casting, preventing injury to workers.
[0044] It should be noted that the above embodiments are illustrative of the present invention and not intended to limit the present invention.
