Description

Technical Field

[0001] The present invention relates to the field of stamping technology, in particular to an automatic processing device for a hollow core of a coupler. Background Art

[0002] A coupler core is a key structure used to optimize electromagnetic wave or optical signal transmission. Its core function is to reduce signal loss by minimizing dielectric material interference, while also improving power handling and thermal stability. Coupler cores typically require a surface projection machined into them. This projection serves as a mounting base for external optical components (such as lenses and reflectors). Mechanical positioning ensures optical axis alignment and reduces optical loss due to assembly deviations.

[0003] Chinese patent CN111389988B discloses a metal tube rolling and bulging device, which includes a base, a rolling and bulging mechanism, a drive and feed mechanism, and a positioning and clamping mechanism. The rolling and bulging mechanism is mounted on the drive and feed mechanism, which in turn are mounted on the base. The tube is then horizontally mounted on the positioning and clamping mechanism.

[0004] The above patents and prior art have the following problems:

[0005] When processing the boss of the current hollow core, the height of each position of the boss protrusion cannot be well in the same plane, and the flatness of the upper and lower surfaces of the boss cannot be uniform, which causes the installed hollow core to deviate when the boss assists in the installation of the hollow core, thereby affecting the assembly of the coupler.

[0027] Beneficial effects of the present invention:

[0028] The arc connection part of the hollow boss is formed by the preliminary die closing and stamping of the first-level sleeve die, the arc section and the convex section one, and then the flatness of the hollow non-convex part is improved through the support rolling of the rolling roller one and the rolling roller two and the movement and straightening of the second-level sleeve die. The double stamping of the first-level sleeve die and the second-level sleeve die makes the hollow boss forming quality high and avoids the metal rebound in the late stage of one-time forming. The combined support rotation and flattening of the rolling head and the impact support plate one and the impact support plate two makes the surface raised height of the boss consistent, and the impact support plate one and the impact support plate two are intermittently used to hit the inner walls of the upper and lower sides of the boss and contact the flat end, so that the upper and lower sides of the boss tend to be flat, and then by processing the hollow boss part and the non-boss part, the hollow forming quality is improved, thereby improving the installation accuracy of the hollow core.

[0029] The rotary drive source is started, and the rotary drive source drives the upper and lower push sources and the linkage disk to rotate, and the linkage disk will rotate synchronously through the external back plate and the central shaft during rotation, and the central shaft will drive the bottom disc and the rotating disc to rotate synchronously through the clip, so that the bottom disc rotates relative to the fixed frame through the cooperation of the inner ring groove and the sliding piece, and then the central shaft will drive the rolling rollers 1 and 2 to rotate and roll on the inner wall of the hollow core during rotation, and cooperate with the secondary sleeve mold constrained on the outside of the hollow core, so as to improve the coaxiality of the upper and lower positions of the vertical part of the hollow core, and under the repeated rolling of the rolling rollers 1 and 2, reduce the stress concentration of the secondary sleeve mold on the movement and straightening of the hollow core, and reduce the subsequent rebound of the hollow core.

[0030] When the central axis rotates inside the hollow core, the central rolling head and the bumper plates 1 and 2 coplanar with the rolling head will rotate and move the inside of the hollow core boss to make it flat, so that the raised heights of the hollow core bosses are in the same plane, and the connecting parts and raised parts of the hollow core are rotated and rolled, thereby improving the flatness of the upper and lower parts of the hollow core bosses.

[0031] When the outer plate and the first and second impact plates rotate, the upper and lower driving sources are started intermittently, so that the upper and lower driving sources drive the linkage plate and the auxiliary rod to move upward through the moving rod, so that the auxiliary rod will drive the back plate and the movable sleeve plate to move upward along the central axis when the back plate moves upward, so that the first impact plate at its bottom will contact the inner wall of the hollow boss, so that the first impact plate will hit the inner wall of the hollow core and make it contact with the flat end part of the side of the secondary sleeve mold above, and when the impact plate moves upward, it will drive the transmission wheel to rotate through the active bar, so that the driven bar will move downward close to the inner wall of the hollow boss through the transmission of the transmission wheel, so that the second impact plate at the bottom of the driven bar will hit the inner wall of the hollow core and make it contact with the flat end part of the side of the secondary sleeve mold below The flat ends of the sides of the secondary sleeve die are partially in contact, so that the impact support plates 1 and 2 move outward synchronously, so that the impact support plates 1 and 2 symmetrically beat the upper and lower sides of the inner wall of the hollow boss, and then the impact support plates 1 and 2 beat, thereby reducing the stress concentration caused by the flat end squeezing the curved part of the boss, and the symmetrical beating of the impact support plates 1 and 2 can improve the flatness of the contact surface between the hollow core and the flat end, and then the impact support plates 1 and 2 are combined with the rolling head to support and rotate the interior of the boss for leveling, and intermittently make the impact support plates 1 and 2 symmetrically beat the upper and lower inner walls of the boss, so that the flatness of the upper and lower sides of the hollow boss is improved, and the heights of the raised parts of the boss at various positions are kept consistent.

[0071] Operation process:

[0072] Hereinafter, the primary sleeve mold 202, the closed driving source 1044, and the secondary sleeve mold 205 corresponding to the upper portion of the eccentric rod 1043 are referred to as the upper primary sleeve mold 202 and the upper closed driving source 1044 or the upper secondary sleeve mold 205, and the primary sleeve mold 202, the closed driving source 1044, and the secondary sleeve mold 205 corresponding to the lower portion of the eccentric rod 1043 are referred to as the lower primary sleeve mold 202 and the lower closed driving source 1044 or the lower secondary sleeve mold 205, and the upper and lower closed connecting portions 301 and the protruding portions 302 constitute a boss.

[0073] The bottom of the hollow core to be processed is manually sleeved on the outside of the positioning round block 1011, so that the output shaft of the closed driving source 1044 below is inserted into the clamping cavity 1 20211 through the clamping block 1045, so that the closed driving source 1044 pushes the connecting block 1 2021, so that the two primary sleeve dies 202 inside the connecting block 1 2021 are closed. Figure 15Step a in the above process causes the bottom of the hollow core to be clamped and closed by the two first-level sleeve molds 202 below. At this time, the two first-level sleeve molds 202 above are also pushed and closed by the upper closing driving source 1044, so that the top of the hollow core is restricted inside the upper closed first-level sleeve mold 202. At this time, the inner diameter of the upper first-level sleeve mold 202 after closing is slightly larger than the diameter of the hollow core, so that the upper first-level sleeve mold 202 can slide downward along the hollow core, and the height of the hollow core is greater than the total height of the rolling rollers 2032 of the upper and lower first-level sleeve molds 202 after closing and docking. Then, the downward driving source 1044 is pushed and closed. 103 and the displacement driving source 1041 are started synchronously, so that the rolling roller 1 2032, the rolling roller 2 2036 and the rolling head 2041 that are retracted to the inner side of the arc groove 2011 and gathered together enter the interior of the hollow core. At this time, there is a gap between the rolling head 2041 and the inner wall of the hollow core, and then the downward driving source 103 pushes the fixed frame 1031 and the bottom disc 10311 to move downward, so that the bottom disc 10311 closes and covers the top opening of the closed first-level sleeve mold 202 above, so that the hollow core and the top of the first-level sleeve mold 202 above are covered by the bottom disc 10311. Figure 2 ;

[0074] Then, the downward driving source 103 drives the bottom disc 10311 and the hollow core, and the displacement driving source 1041 drives the closed first-stage sleeve mold 202 to move synchronously, so that the upper and lower first-stage sleeve molds 202 are gradually closed, that is, the convex sections 2023 on the opposite surfaces of the upper and lower first-stage sleeve molds 202 are relatively closed, so that the hollow core becomes convex toward the outer shape under the action of the punching pressure, and gradually the top of the hollow core is constrained by the bottom disc 10311 and the first-stage sleeve mold 202 and driven downward, so that the middle of the hollow core is The upper portion moves toward the space between the upper and lower sleeve dies 202, that is, moves toward the arc segment 2022, so that the middle portion of the hollow core is gradually punched and bent to expand the tube outward. Then, when the upper and lower raised segments 2023 are closed, under the action of the extrusion force of the downward driving source 103, the hollow core that is squeezed and expanded outward is formed in the cavity formed by the upper and lower arc segments 2022 and the raised segment 2023, so that the middle portion of the hollow core is preliminarily punched and expanded to form a boss with a surface curvature. Figure 4 ;

[0075] Then the downward driving source 103 is moved upward, and the closed driving source 1044 is pulled back outward, so that the constraint on the outer side of the initially formed hollow core is released, and the moving block 1042 is raised to a preset height along the eccentric rod 1043, so that the closed driving source 1044 pulls the first-level sleeve die 202 to reset, so that the initially formed hollow core is still sleeved on the top of the positioning round block 1011, and then the downward driving source 103 is moved downward, so that the rolling roller 1 2032, the rolling roller 2036 and the rolling head 2041 at the bottom of the downward driving source 103 continue to move downward to the hollow core. The inner part is finally located at the middle of the boss, and the expansion and contraction rotation source 10313 is started, so that the expansion and contraction rotation source 10313 rotates through the active member 10317 installed on the output shaft at the bottom thereof, and the active member 10317 rotates through the transmission member 10316 and the driven member 10315, so that the driven member 10315 rotates, and the driven member 10315 drives the rotating disk 201 to rotate, so that the arc groove 2011 on the surface of the rotating disk 201 drives the clip 2031 and the central axis 203 during the rotation. The inner portion thereof moves outward along its arc, thereby causing the clip 2031 and the central axis 203 located at the surface of the moving groove 10318 at the bottom of the arc groove 2011 to move outward along the moving groove 10318. During the movement of the clip 2031 and the central axis 203, the back plate 2033 at the bottom thereof also moves outward along the auxiliary rod 10333, wherein the auxiliary rod 10333 is parallel to the moving groove 10318 at its top, thereby causing the clip 2031 and the central axis 203 to move outward, causing the surfaces of the rolling roller 1 2032 and the rolling roller 2 2036 to contact the air. The inner wall of the core fits, and the rolling head 2041 is inserted into the interior of the hollow core boss. The upper and lower support plates 1 2034 and 2035 of the rolling head 2041 are flush with the upper and lower surfaces of the rolling head 2041, respectively, so that the rolling rollers 1 2032 and 2036 perform internal contact constraints on the hollow core, and then the rolling rollers 1 2032 and 2036 support the interior of the hollow core through contact constraints and the positioning round block 1011 is sleeved on the interior of the hollow core, thereby reducing the eccentric movement of the hollow core during subsequent stamping;

[0076] Then, the first-level sleeve mold 202 is replaced with the second-level sleeve mold 205, and the second-level sleeve mold 205 is inserted into the interior of the clamping block 1045 through the clamping cavity 2052 outside the connecting block 2051, so that the lower closing driving source 1044 pushes the lower second-level sleeve mold 205 to close on the surface of the hollow core, and at this time, the upper closing driving source 1044 pushes the clamping block 1045 and the connecting block 2051 to move, so that the second-level sleeve mold 205 inside the connecting block 2051 is closed above the hollow core, thereby making the upper and lower sides of the hollow core active. The dynamic closure is provided with a secondary sleeve die 205, i.e., the internal diameter of the secondary sleeve die 205 after closing is slightly larger than the diameter of the hollow core, because the height of the secondary sleeve die 205 is lower than that of the primary sleeve die 202, and by adjusting the positions of the output shafts of the displacement driving source 1041 and the bottom driving source 1012, the upper and lower secondary sleeve dies 205 are adjusted to correspond to the upper and lower positions of the hollow core bosses, so that the flat end 2053 and the second raised section 2054 of the secondary sleeve die 205 do not contact the boss initially formed on the surface of the hollow core and the bottom disc 10311;

[0077] Then, the displacement driving source 1041 and the bottom driving source 1012 are synchronously activated, so that the upper and lower closed secondary sleeve molds 205 move toward the boss portion of the hollow core. Then, during the movement of the secondary sleeve mold 205 and under the internal support and restriction of the first rolling roller 2032 and the second rolling roller 2036, the surface of the hollow core is straightened by the movement of the secondary sleeve mold 205, thereby improving the subsequent installation accuracy of the hollow core.

[0078] During the opposite movement of the upper and lower closed secondary sleeve molds 205, the flat ends 2053 and the raised section 2054 on the opposite surfaces of the upper and lower closed secondary sleeve molds 205 are in closed contact with the connection part 301 of the raised arc on the surface of the boss, so that when the raised section 2054 is closed, the flat end 2053 pushes the connection part 301 of the arc originally formed along the arc section 2022 on the hollow surface to be squeezed flat. The connection part 301 of the arc is formed between the vertical part 3 and the raised part 302 of the hollow core, so that the flat end 2053 squeezes the connection part 301 of the raised arc of the hollow core into contact with the collision support plate 1 2034 and the collision support plate 2 2035, and then, under the support of the collision support plate 1 2034 and the collision support plate 2 2035, the boss is not easy to collapse excessively during the squeezing into the inside of the boss, thereby ensuring the flatness of the upper and lower parts of the hollow boss.

[0079] Embodiment 2: This embodiment differs from the first embodiment in that:

[0080] like Figure 7-10 and Figure 13As shown, a support member 2012 is movably provided on the top of the bottom disc 10311. The support member 2012 is preferably a universal ball. The support member 2012 is fixedly connected to the surface of the rotating disc 201. The output shaft of the up and down driving source 1033 movably passes through the rotating disc 201 and the bottom disc 10311 and is fixedly connected to the linkage disc 10332.

[0081] The outer ring of the linkage disk 10332 is provided with several groups of auxiliary rods 10333, and two auxiliary rods 10333 form a group. The surface of one group of auxiliary rods 10333 is movably sleeved with a back plate 2033, and the top of the back plate 2033 is fixedly connected with a movable sleeve plate 20331. The movable sleeve plate 20331 is movably set on the surface of the central axis 203, and the movable sleeve plate 20331 is movably set between the clip 2031 and the rolling roller 2032.

[0082] like Figure 14 As shown, the bottom of the back plate 2033 is fixedly connected to a collision support plate 2034, and the collision support plate 2034 is movably sleeved on the surface of the central axis 203. The bottom of the collision support plate 2034 is fixedly connected to an active strip 20341 and a limiting rod 20342;

[0083] The bottom of the limiting rod 20342 is fixedly connected to a round block, which is used to limit the collision support plate 2035 from separating from the limiting rod 20342. Of course, in order to make the collision support plate 2035 supported, a spring can be set on the surface of the central axis 203, so that the rolling roller 2036 supports the collision support plate 2035 through the spring, and the central axis 203 at the top of the corresponding collision support plate 1 2034 should also be set with a spring of the same specification, so that the rolling roller 1 2032 is movably connected to the collision support plate 1 2034 through the spring, and the distance between the rolling roller 1 2032 and the collision support plate 1 2034 is the same as the distance between the rolling roller 2 2036 and the collision support plate 2035, and then under the influence of the spring support, the collision support plate 1 2034 and the collision support plate 2035 have the same distance of movement up and down. The surface of the limiting rod 20342 is movably provided with a collision support plate 2035, and the top of the collision support plate 2035 is fixedly connected with a driven bar 20352.

[0084] like Figure 14 As shown, an extension plate 204 is provided between the first and second collision support plates 2034 and 2035. A protruding plate 2042 is fixedly connected to the side of the extension plate 204 opposite to the rolling head 2041. A transmission wheel 2043 is rotatably provided on the surface of the protruding plate 2042. The active bar 20341 is meshed and connected with the driven bar 20352 through the transmission wheel 2043. The transmission wheel 2043 is preferably a transmission gear, and the active bar 20341 and the driven bar 20352 are preferably racks.

[0085] The active strip 20341 is provided with a second opening 20351 on the surface of the second collision support plate 2035, and the driven strip 20352 is provided with a first opening 20343 on the surface of the first collision support plate 2034. The rolling head 2041 is preferably a semicircular block or roller with chamfered sides.

[0086] The rest of the structure is the same as that of the first embodiment.

[0087] Operation process:

[0088] The rotation drive source 1032 is started, and the rotation drive source 1032 drives the upper and lower push sources 1033 and the linkage disk 10332 to rotate, and the linkage disk 10332 rotates synchronously through the external back plate 2033 and the central shaft 203, and the central shaft 203 rotates synchronously with the bottom disc 10311 and the rotating disc 201 through the clip 2031, so that the bottom disc 10311 cooperates with the inner ring groove 10319 and the sliding piece 103111 to make the bottom disc 10311 rotates relative to the fixed frame 1031, and the central axis 203 rotates, which drives the first rolling roller 2032 and the second rolling roller 2036 to rotate and roll on the inner wall of the hollow core, cooperating with the secondary sleeve die 205 constrained on the outer side of the hollow core, thereby improving the coaxiality of the upper and lower positions of the vertical portion 3 of the hollow core. Under the repeated rolling of the first rolling roller 2032 and the second rolling roller 2036, the stress concentration of the secondary sleeve die 205 on the movement and straightening of the hollow core is reduced, thereby reducing the subsequent rebound of the hollow core.

[0089] When the central shaft 203 is located inside the hollow core and rotates, the rolling head 2041 in the middle and the first and second collision support plates 2034 and 2035 coplanar with the rolling head 2041 rotate and move the interior of the hollow core boss to smooth it, so that the raised heights of the hollow core boss are in the same plane, and the connecting portion 301 and the raised portion 302 of the hollow core are rotated and rolled, thereby improving the smoothness of the upper and lower surfaces of the hollow core boss.

[0090] During the rotation of the extension plate 204 and the collision support plate 1 2034 and the collision support plate 2 2035, the upper and lower driving sources 1033 are intermittently started, so that the upper and lower driving sources 1033 drive the linkage plate 10332 and the auxiliary rod 10333 to move upward through the moving rod 10331, so that the auxiliary rod 10333 moves upward and drives the back plate 2033 and the movable sleeve plate 20331 to move upward along the central axis 203, so that the collision support at the bottom of the back plate 2033 moves upward. The first plate 2034 contacts the inner wall of the hollow boss, so that the first support plate 2034 hits the inner wall of the hollow core and contacts the flat end 2053 of the side of the secondary sleeve mold 205 above. When the first support plate 2034 moves upward, it drives the transmission wheel 2043 to rotate through the active bar 20341, so that the driven bar 20352 moves downward and approaches the inner wall of the hollow boss through the transmission of the transmission wheel 2043, so that the second support plate 2034 at the bottom of the driven bar 20352 035 hits the inner wall of the hollow core so that it contacts the flat end 2053 of the side of the secondary sleeve die 205 below, thereby causing the first and second collision support plates 2034 and 2035 to move outward synchronously, so that the first and second collision support plates 2034 and 2035 symmetrically hit the upper and lower sides of the inner wall of the hollow core boss, thereby reducing the stress concentration caused by the flat end 2053 squeezing the curved part of the boss through the collision of the first and second collision support plates 2034 and 2035, and The symmetrical beating of the first and second impact support plates 2035 can improve the flatness of the contact surface between the hollow core and the flat end 2053, and then the interior of the boss is supported and rotated to be flattened by the combination of the first and second impact support plates 2034 and 2035 and the rolling head 2041, and the upper and lower inner walls of the boss are symmetrically beat by the first and second impact support plates 2034 and 2035 intermittently, thereby improving the flatness of the upper and lower sides of the boss of the hollow core and making the height of the boss protrusion 302 at each position consistent;

[0091] When the secondary sleeve die 205 completes the processing of the hollow core, the rolling head 2041 is retracted and then lifted, so that the secondary sleeve die 205 is closed and opened, so that the hollow core can be easily taken out from the top of the positioning round block 1011;

[0092] In summary, the arc connecting portion 301 of the hollow boss is formed by the preliminary die-closing stamping of the first sleeve die 202, the arc segment 2022 and the convex segment 1 2023, and then the straightening by the support rolling of the rolling roller 1 2032 and the rolling roller 2 2036 and the movement straightening of the second sleeve die 205 improves the straightness of the hollow non-boss portion. The double stamping of the first sleeve die 202 and the second sleeve die 205 makes the hollow boss forming quality high, avoiding the metal deformation in the later stage of the primary forming. Rebound, and then cooperate with the combined support of the rolling head 2041, the impact support plate 1 2034 and the impact support plate 2035 to rotate smoothly, so that the surface protrusion height of the boss convex part 302 is consistent, and cooperate with the intermittent impact support plate 1 2034 and the impact support plate 2035 to hit the inner walls of the upper and lower sides of the boss and contact with the flat end 2053, so that the upper and lower sides of the boss tend to be smooth, and then by processing the hollow boss part and the non-boss part, the hollow core molding quality is improved, thereby improving the installation accuracy of the hollow core.
