DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Figures 1 to 9 It is apparent that the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0042] An electronic stylus body processing and forming equipment, referring to Figure 1 , comprising a rectangular machine table 1, a forming seat 2 arranged on the machine table 1, and a shaft sleeve 3 rotatably arranged on the forming seat 2. The forming seat 2 is also rectangular, and the forming seat 2 is distributed along the length direction of the machine table 1, and the top of the forming seat 2 is open. The shaft sleeve 3 is long strip-shaped, and the shaft sleeve 3 is distributed along the length direction of the forming seat 2, and the shaft sleeve 3 is arranged in the forming seat 2, and both ends of the shaft sleeve 3 extend out of the forming seat 2. A shaft sleeve cavity is arranged in the shaft sleeve 3, and the shaft sleeve cavity is arranged along the axial direction of the shaft sleeve 3, and the shaft sleeve cavity penetrates through both ends of the shaft sleeve 3.

[0043] Referring to Figure 1 and Figure 2 , the shaft sleeve 3 is provided with a forming die 4 and a die clamping assembly 5 for clamping or loosening the forming die 4. The forming die 4 is columnar, and the forming die 4 is distributed along the axial direction of the shaft sleeve 3, and the cross section of the forming die 4 is cross-shaped, and the forming die 4 is made of CR12# steel material, wherein the CR12# steel material has excellent wear resistance, is suitable for long time high load use, and is beneficial to bearing larger cutting pressure.

[0044] In this embodiment, referring to Figure 3 and Figure 4A long tubular aluminum extrusion profile is used to make the pen body, and one end of the aluminum extrusion profile is used as the pen tip. The pen tip is aligned and inserted into a forming mold 4, and the forming mold 4 is driven to rotate and cut the pen tip, so that the pen tip is formed.

[0045] Reference Figure 2 and Figure 4 A forming hole 6 is formed at one end of the forming die 4. The shape of the forming hole 6 and the pen tip end are adapted to each other, that is, the forming hole 6 gradually shrinks along the length direction of the forming die 4. Therefore, by aligning the pen tip end of the aluminum extruded profile and inserting it into the forming hole 6, and driving the forming die 4 to rotate, the pen tip end can be cut and formed. In addition, a guide groove 7 is also formed on the forming die 4. The guide groove 7 is used to guide the aluminum extruded profile into the forming hole 6. The guide groove 7 and the forming hole 6 are located at the same end of the forming die 4. The guide groove 7 surrounds the forming hole 6 and is connected to the forming hole 6, thereby effectively reducing position deviation during the insertion process.

[0046] Specifically, refer to Figure 2 and Figure 5 The forming mold 4 is assembled by splicing multiple mold parts 41. For comprehensive consideration of the mold accuracy and formability, in this embodiment, the forming mold 4 is assembled by splicing four mold parts 41. The four mold parts 41 are consistent and closely distributed along the circumferential direction of the sleeve 3.

[0047] During molding, the molding die 4 is clamped by the die clamping assembly 5 to prevent the mold split 41 from shifting, and the shaft sleeve 3 is driven to rotate. The shaft sleeve 3 drives the die clamping assembly 5 and the molding die 4 to rotate, and the aluminum extruded profile is driven to align the pen tip and extend it into the molding die 4, and the molding die 4 is driven to rotate and cut the pen tip end. The pen tip end is cut to form the pen tip end.

[0048] Specifically, refer to Figure 1 and Figure 6 The clamping assembly 5 includes a mold mounting seat 51 arranged at one end of the sleeve 3, a chuck sleeve 52 arranged in the sleeve cavity, and an elastic chuck 53 slidably arranged on the chuck sleeve 52.

[0049] Reference Figure 6 and Figure 7 One end of the mold mounting seat 51 extends into the shaft sleeve cavity, and the mold mounting seat 51 is connected to the shaft sleeve 3 by bolts. The mold mounting seat 51 is provided with a mounting groove 61. The shape of the mounting groove 61 is adapted to the forming mold 4. That is, the mounting groove 61 is cross-shaped and distributed along the axial direction of the shaft sleeve 3. The mounting groove 61 passes through the mold mounting seat 51 and is connected to the shaft sleeve cavity. The forming mold 4 is located in the mounting groove 61, and the forming hole 6 faces outward.

[0050] Reference Figure 6 andFigure 7 The chuck sleeve 52 is cylindrical and distributed along the axial direction of the sleeve 3, and the chuck sleeve 52 is connected to the sleeve 3, so that when the sleeve 3 rotates, the sleeve 3 drives the chuck sleeve 52 to rotate. A chuck slide 54 is slidably arranged in the chuck sleeve 52. The chuck slide 54 is cylindrical and distributed along the axial direction of the chuck sleeve 52. The chuck slide 54 slides and cooperates with the chuck sleeve 52 along the axial direction of the sleeve 3. A protruding shaft 55 is provided on the side wall of the chuck slide 54. The chuck sleeve 52 is provided with an elongated sliding groove 56 corresponding to the protruding shaft 55. The sliding groove 56 is distributed along the axial direction of the sleeve 3. The protruding shaft 55 extends into the sliding groove 56, and the protruding shaft 55 and the sliding groove 56 slide and cooperate along the driving and clamping direction. In addition, it should be noted that in this embodiment, the axial direction of the sleeve 3 is the driving and clamping direction. When the chuck slide 54 slides along the driving clamping direction, the cam 55 slides along the length direction of the slide groove 56. The cam 55 and the slide groove 56 limit the sliding position and distance of the chuck slide 54. When the chuck sleeve 52 rotates, the chuck sleeve 52 drives the cam 55 to rotate, thereby causing the cam 55 to drive the chuck slide 54 to rotate.

[0051] Reference Figure 6 and Figure 7 Two protruding shafts 55 are provided, and the two protruding shafts 55 are evenly spaced along the circumference of the chuck slide 54. Two sliding grooves 56 are provided corresponding to the number of protruding shafts 55. The two protruding shafts 55 slide and cooperate with the two sliding grooves 56 in a one-to-one correspondence. Therefore, the two protruding shafts 55 and the two sliding grooves 56 make the sliding and rotation process of the chuck slide 54 more stable.

[0052] Reference Figure 6 and Figure 7 The elastic chuck 53 includes a chuck bottom 531 and a chuck head 532 connected to one end of the chuck bottom 531 , wherein the chuck head 532 extends into the mold mounting seat 51 located at one end of the sleeve 3 , so that the chuck head 532 is connected to the mounting groove 61 , and one end of the forming mold 4 extends into the chuck head 532 .

[0053] Reference Figure 6 and Figure 7The clamping head part 532 comprises at least two clamping pieces 5321. In this embodiment, four clamping pieces 5321 are arranged along the circumferential direction of the clamping head sleeve 52. Elastic gaps 8 are formed between adjacent two clamping pieces 5321, which are used to provide space for opening or tightening the clamping head part 532. In addition, a tapered guide block 5322 is arranged on each clamping piece 5321, which is located on the outer side of the clamping piece 5321, and the taper surface gradually expands from the clamping bottom part 531 to the clamping head part 532. The clamping head slide 54 is also provided with a bottom groove 62, which is matched with the clamping bottom part 531, and the bottom groove 62 is distributed along the axial direction of the shaft sleeve 3. The bottom groove 62 penetrates the clamping head slide 54, and the clamping bottom part 531 extends into the bottom groove 62. In combination with the tapered guide block 5322, the clamping head slide 54 is limited in the axial direction of the shaft sleeve 3. Figure 8 The end of the clamping head slide 54 close to the clamping head part 532 is provided with an outwardly flared extrusion edge 9. The mold mounting seat 51 is also provided with a necking edge 12, which abuts with the large head end of the tapered guide block 5322, thereby limiting the elastic clamping head 53.

[0054] When the clamping head slide 54 slides in the driving clamping direction, the convex shaft 55 slides along the length direction of the sliding groove 56, limiting the sliding position and distance of the clamping head slide 54, so that the necking edge 12 abuts with the large head end of the tapered guide block 5322, and the extrusion edge 9 abuts with the guide block 5322. The extrusion edge 9 and the guide block 5322 cooperate to extrude the clamping piece 5321, so that the four clamping heads are tightened in the direction of the central axis of the shaft sleeve 3, i.e. the elastic gap 8 is compressed, thereby clamping the forming mold 4.

[0055] Referring to Figure 6 In combination with Figure 8 The mold clamping assembly 5 further comprises a sliding rod 57 slidingly arranged in the shaft sleeve 3 and an elastic member 58 arranged at one end of the sliding rod 57. The sliding rod 57 is a circular rod, which is distributed along the axial direction of the shaft sleeve 3. One end of the sliding rod 57 faces the clamping head slide 54, and the other end of the sliding rod 57 extends out of the shaft sleeve 3. The sliding rod 57 is integrally formed with a sliding block 59, which surrounds the outer wall of the sliding rod 57. The shaft sleeve 3 is provided with a sliding groove 60 corresponding to the sliding block 59, which is matched with the sliding block 59 in the driving clamping direction, so that the sliding rod 57 and the shaft sleeve 3 are matched with each other in sliding manner, and the sliding rod 57 is prevented from falling off the shaft sleeve 3. The elastic member 58 is a spring, one end of the sliding rod 57 facing the clamping head slide 54 is connected with one end of the elastic member 58, and the other end of the elastic member 58 extends into the bottom groove 62 and abuts with the clamping bottom part 531. The elastic member 58 is used to provide elastic force to keep the necking edge 12 abutting with the large head end of the guide block 5322 and assist the clamping head slide 54 to reset.

[0056] When clamping the forming mold 4, the driving slide 57 moves in the driving clamping direction, driving the slider 59 to slide along the sliding groove 60. At the same time, the slide 57 pushes the chuck slide 54 to slide. At this time, the elastic member 58 contracts, the closing edge 12 abuts against the tapered large end of the guide block 5322, and the extrusion edge 9 abuts against the guide block 5322. The extrusion edge 9 and the guide block 5322 cooperate to squeeze the clip 5321, so that all four chucks are tightened toward the central axis of the sleeve 3, thereby clamping the forming mold 4. When releasing the forming mold 4, the driving slide 57 returns to its original position, the elastic member 58 is released, and the chuck slide 54 returns to its original position. The elastic force of the elastic chuck 53 restores the elastic gap 8 to its original size, thereby releasing the forming mold 4.

[0057] Reference Figure 1 and Figure 9 The machine 1 is also provided with a driving tensioning assembly 10 for driving the slide bar 57 to move along the driving clamping direction. The driving tensioning assembly 10 includes a driving seat 101 provided on the machine 1 and a driving member 102 provided on the driving seat 101.

[0058] Reference Figure 1 and Figure 9 The end of the slide rod 57 extending from the shaft sleeve 3 is sleeved with a drive wheel 103. The sidewall of the drive wheel 103 is provided with a circle of wheel grooves 104, which are distributed along its own circumferential direction. The drive member 102 is a cylinder, and the drive member 102 is distributed along the drive clamping direction. The drive end of the drive member 102 is provided with a drive block 105, which extends into the wheel groove 104. The drive member 102 causes the drive block 105 to move in the drive clamping direction. At this time, the drive block 105 drives the drive wheel 103 to move, thereby driving the slide rod 57 in the drive clamping direction.

[0059] When clamping the forming mold 4, the driving member 102 moves the driving block 105 in the driving and clamping direction. The driving block 105 drives the driving wheel 103 to move, thereby driving the slide bar 57 in the driving and clamping direction, causing all four chucks to tighten toward the central axis of the sleeve 3, thereby clamping the forming mold 4. When releasing the forming mold 4, the driving member 102 resets the driving block 105, which in turn resets the driving wheel 103. The elastic member 58 is released and drives the chuck slide 54 to reset, and the elastic gap 8 returns to its original size, thereby releasing the forming mold 4.

[0060] During molding, the driving member 102 moves the driving block 105 in the driving clamping direction, which drives the driving wheel 103 to move, thereby driving the slide bar 57 in the driving clamping direction and driving the slider 59 to slide along the sliding groove 60. At the same time, the slide bar 57 pushes the chuck slide 54 to slide in the driving clamping direction. At this time, the elastic member 58 contracts, the closing edge 12 abuts against the tapered large end of the guide block 5322, and the extrusion edge 9 abuts against the guide block 5322. The extrusion edge 9 and the guide block 5322 cooperate to squeeze the clip 5321, so that all four chucks are tightened toward the central axis of the sleeve 3, thereby clamping the molding die 4. Then, the sleeve 3 is driven to rotate, which drives the mold mounting base 51, the chuck sleeve 52, the chuck slide 54, and the elastic chuck 53 to rotate, thereby driving the molding die 4 to rotate, preventing the mold split 41 from shifting during rotation. The aluminum extruded profile is driven to align the pen tip and extend it into the forming mold 4, and the forming mold 4 is driven to rotate and cut the pen tip, so that the pen tip is cut and formed.

[0061] Continue to refer to Figure 1 and Figure 9 The machine 1 is also provided with a rotating assembly 11 for driving the shaft sleeve 3 to rotate. The rotating assembly 11 includes a driving box 111 provided on the machine 1 and a first transmission wheel 112 rotatably provided in the driving box 111.

[0062] Continue to refer to Figure 1 and Figure 9 A second transmission wheel 113 is mounted on the end of the sleeve 3 facing away from the mold mounting base 51. A transmission belt 114 is disposed between the first transmission wheel 112 and the second transmission wheel 113. The transmission belt 114 is wrapped around the first and second transmission wheels 112, 113. The transmission method of the first and second transmission wheels 112, 113, and the transmission belt 114 is a well-established technique in the prior art and will not be described in detail. A motor 115 is mounted on the drive box 111 to drive the first transmission wheel 112. The output shaft of the motor 115 is connected to the axle of the first transmission wheel 112.

[0063] Thus, the first transmission wheel 112 is driven to rotate by the motor 115 , the first transmission wheel 112 causes the transmission belt 114 to rotate, the transmission belt 114 drives the second transmission wheel 113 to rotate, and the second transmission wheel 113 drives the shaft sleeve 3 to rotate.

[0064] The implementation principle of the present application is: during molding, the driving block 105 is moved along the driving clamping direction through the driving member 102, and the driving block 105 drives the driving wheel 103 to move, thereby driving the slide rod 57 to move along the driving clamping direction, and driving the slider 59 to slide along the sliding groove 60. At the same time, the slide rod 57 pushes the chuck slide 54 to slide along the driving clamping direction. At this time, the elastic member 58 is contracted, and the closing edge 12 and the tapered large head end of the guide block 5322 abut against each other, and the extrusion edge 9 abuts against the guide block 5322. The extrusion edge 9 and the guide block 5322 cooperate with the extrusion clip 5321 to tighten the four chucks toward the center axis of the sleeve 3, thereby clamping the molding mold 4. The motor 115 drives the first transmission wheel 112 to rotate. The first transmission wheel 112 rotates the transmission belt 114, which drives the second transmission wheel 113 to rotate. The second transmission wheel 113 drives the shaft sleeve 3 to rotate. The rotation of the shaft sleeve 3 drives the mold mounting base 51, the chuck sleeve 52, the chuck slide 54, and the elastic chuck 53 to rotate, thereby driving the forming mold 4 to rotate, preventing the mold body 41 from shifting during rotation. By driving the aluminum extruded profile to align the pen tip and extend it into the forming mold 4, and driving the forming mold 4 to rotate and cut the pen tip, the pen tip is cut and formed, thereby quickly forming the pen body.

[0065] Therefore, further processing is carried out based on the original aluminum extrusion profile, and the improved pen body is obtained by cutting using this application, which is conducive to maximizing the use of existing aluminum profiles, improving resource utilization, reducing process flow, and saving costs.

[0066] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
