Description

Technical Field

[0001] The present invention relates to the technical field of forging and pressing forming, and particularly relates to a forging and pressing forming device for a titanium alloy mobile phone frame with a microporous structure. Background Art

[0002] In the field of metal processing, forging and pressing forming is an important plastic processing technology. This technology applies pressure to cause plastic deformation of a metal blank under the action of a mold, thereby obtaining the required shape and size.

[0003] In recent years, with the rapid development of smart phones, the requirements for mobile phone frame materials have become increasingly high. Titanium alloy, with its excellent properties such as high strength, light weight, and corrosion resistance, has gradually become an ideal choice for high-end smart phone frames. The forging and pressing forming process of titanium alloy mobile phone frames can fully utilize the performance advantages of titanium alloy materials.

[0004] In the existing forging and pressing forming technology of titanium alloy mobile phone frames, a split forging method is usually adopted, and the titanium alloy blank is limited by opening hole grooves, etc. However, during the forging process, the titanium alloy blank will undergo plastic deformation under the action of huge pressure, and a simple limiting structure cannot avoid irregular displacement and deformation of the blank in all directions during compression. This will not only affect the dimensional accuracy and surface quality of the final product, but may also cause problems such as stress concentration and internal defects of the blank after forging and pressing forming. Summary of the Invention

[0023] The clamping group 232 includes a rectangular plate 2321 slidably arranged on the upper surface of the supporting table 2 through a telescopic plate. A rectangular groove is opened on the side wall of the rectangular plate 2321 close to the mounting plate 2311 and corresponding to the positions of the three U-shaped grooves 22. A pushing block 2322 with a roller mounted on the end face is arranged inside the rectangular groove through a spring.

[0024] The forging group 11 includes a supporting bracket 111 slidably arranged on the side wall of the forging press body 1. A hydraulic push rod 112 is fixedly arranged inside the supporting bracket 111 through a square plate. The telescopic section of the hydraulic push rod 112 slidably penetrates through the supporting bracket 111 and a forging member for forging the titanium alloy blank is fixedly arranged on the lower end face of the telescopic section. A wedge-shaped top plate 113 is fixedly arranged at the front end of the forging member through a connecting plate.

[0025] The driving group 24 includes two threaded rods 241 arranged in the vertical direction and the upper ends of which are threadedly connected to the supporting frame 111. The lower end surface of the threaded rod 241 rotates through the supporting platform 2 and the forging machine body 1 and is fixedly connected to the output shaft of the external driving motor. The upper end surface of the supporting platform 2 and the outer wall of the threaded rod 241 are fixedly connected with a gear 242. The toothed part of the gear 242 is meshed with an L-shaped rack 243 that slides on the surface of the supporting platform 2 and is slidably connected to the rectangular plate 2321 through a spring.

[0026] The driving group 24 also includes an active bevel gear 244 disposed inside the return groove and fixedly connected to the outer wall of the threaded rod 241. The front and rear ends of the active bevel gear 244 are symmetrically provided with driven bevel gears 245 that are always meshed with it and rotatably connected to the return groove through the shaft.

[0027] The linkage group 25 includes three synchronous pulleys 251 arranged inside the return groove, among which the leftmost synchronous pulley 251 is fixedly set on the outer wall of the shaft of the corresponding driven bevel gear 245, and the end faces of the other two synchronous pulleys 251 are provided with avoidance grooves and are rotatably set between two adjacent U-shaped grooves 22 respectively. The three synchronous pulleys 251 are connected by transmission through a synchronous belt 252.

[0028] Rollers are fixedly provided in the middle and on the end faces of the right synchronous pulley 251 in the up and down directions, a waist plate 2511 is hingedly provided on the outer wall of the upper roller, and the other end of the waist plate 2511 is hingedly provided to the outer wall of any mounting plate 2311, and two waist plates 2512 are hingedly provided on the outer wall of the lower roller, and the two waist plates 2512 are hingedly provided to the outer walls of the remaining mounting plates 2311.

[0029] The support group 26 includes a T-shaped support block 261 which is slidably arranged inside the U-shaped groove 22 through a spring and whose upper end face is in contact with the titanium alloy blank. A clamping block 262 which is inclined downward is fixedly arranged on the front side wall of the T-shaped support block 261. A matching groove is provided on the end face of the clamping block 262. A V-shaped frame 263 which matches the matching groove is installed at the position of the clamping block 262 inside the rectangular slide groove 21 through a torsion spring. The end of the V-shaped frame 263 away from the clamping block 262 is arranged as a telescopic structure, and a wedge block 264 which is arranged inside the support platform 2 and slides through the rectangular slide groove 21 is installed on one side of the telescopic structure.

[0030] During the specific work, the placement and alignment of the titanium alloy billet: First, three preheated titanium alloy blanks are placed on the U-shaped groove 22 of the supporting table 2 by an external conveying device (the width of the titanium alloy blank is slightly narrower than the width of the U-shaped groove 22, and the purpose is to reserve space for the later deformation of the titanium alloy blank. Since the length of the titanium alloy blank is longer than the length of the U-shaped groove 22 in the initial state, the titanium alloy blank will not fall when placed above the U-shaped groove 22). After the three titanium alloy blanks are placed, the driving motor connected to the two threaded rods 241 is controlled to work and drive the two threaded rods 241 to rotate. During the rotation of the two threaded rods 241, the supporting bracket 111 slidably connected to the forging press body 1 is gradually driven to slide downward.

[0031] During this process, the two threaded rods 241 continue to rotate, and the gears 242 fixedly connected to their outer walls respectively engage with the corresponding L-shaped racks 243 and drive the two L-shaped racks 243 to approach each other. During the approaching process of the two L-shaped racks 243, they synchronously drive the rectangular plates 2321 connected to them to move, and three pushing blocks 2322 provided on the two rectangular plates 2321 complete the pressing work on the titanium alloy blank in the front-rear direction (as the two L-shaped racks 243 continue to approach synchronously, since the pushing blocks 2322 are slidably arranged in the rectangular groove through springs, and at the same time, since the rectangular plates 2321 and the L-shaped racks 243 are slidably connected through springs, after the front and rear pushing blocks 2322 complete the limiting work on the titanium alloy blank, the front and rear rectangular plates 2321 will stop moving under the block of the titanium alloy blank and fit against the outer wall of the titanium alloy blank). The limiting work on the titanium alloy blank in the front-rear direction is completed through the single downward movement of the supporting bracket 111, avoiding the position deviation of the titanium alloy blank in the front-rear direction before forging, thereby causing deviation in the size of the U-shaped half-frame after forging.

[0032] Meanwhile, during the rotation of the two threaded rods 241, the driving bevel gears 244 fixedly connected to their outer walls are driven to rotate. During the rotation of the driving bevel gears 244, the front and rear driven bevel gears 245 are respectively engaged to rotate. When the two driven bevel gears 245 rotate, they respectively drive three synchronous belt wheels 251 on the same side to rotate through the synchronous belt 252. When the synchronous belt wheels 251 in the middle and on the right side rotate, the waist-shaped plates 1 2511 and the waist-shaped plates 2 2512 hinged to their outer walls will respectively pull the mounting plates 2311 located on both sides of the U-shaped groove 22 to approach synchronously (the synchronous belt wheels 251 in the middle and on the right side are arranged between two adjacent U-shaped grooves 22. The mounting plates 2311 slidably arranged on the upper end surface of the supporting table 2 are divided into two left and right adjustment groups by the synchronous belt wheels 251 in the middle and on the right side. Each adjustment group includes three mounting plates 2311. The waist-shaped plates 1 2511 hinged on the synchronous belt wheels 251 in the middle and on the right side are respectively hinged to the mounting plates 2311 near the middle in the two adjustment groups, while the waist-shaped plates 2 2512 hinged on the synchronous belt wheels 251 in the middle and on the right side are respectively hinged to the left and right mounting plates 2311 in the two adjustment groups to ensure that when the synchronous belt 252 drives the three synchronous belt wheels 251 to rotate, it always drives the mounting plates 2311 on both sides of the U-shaped groove 22 to approach or move away synchronously). By the synchronous approach of the mounting plates 2311 on both sides of the U-shaped groove 22, the limiting work in the left and right directions of the titanium alloy blank is completed to ensure that before the forging work of the titanium alloy blank, the distances between its two sides and the U-shaped groove 22 are the same, guarantee the uniformity of the deformation of the titanium alloy blank during the forging work in the later stage, and avoid the problem of asymmetry of the U-shaped half-frame after forging caused by inconsistent distances on both sides.

[0033] As the threaded rod 241 continues to work, the supporting bracket 111 gradually moves downward and first adheres to the supporting table 2. A number of telescopic rods (not shown in the specification drawings) are installed on the forging press body 1, and the purpose is to avoid direct rigid contact between the supporting bracket 111 and the supporting table 2. The force exerted by the supporting bracket 111 on the supporting table 2 during the downward movement is dispersed by a number of telescopic rods, so as to reduce the vibration caused by the pressure during the contact between the supporting table 2 and the supporting bracket 111.

[0034] It should be noted that when the titanium alloy blank is placed above the U-shaped groove 22 and is ready for forging and forming, the T-shaped bearing block 261 inside the U-shaped groove 22 will fit with the lower surface of the titanium alloy blank under the action of the spring. The provided T-shaped bearing block 261 provides effective support for the titanium alloy blank to prevent the blank from being affected by gravity due to being suspended below after preheating, thereby causing unnecessary deformation.

[0035] Forging work of the titanium alloy blank: After the titanium alloy billet is limited in multiple directions, the hydraulic push rod 112 is controlled to drive the forging part (not shown in the drawings of the specification) to extend, and the forging part is gradually pressed downward after contacting the upper surface of the titanium alloy billet, so that the titanium alloy billet gradually enters the U-shaped groove 22 and is shaped (during the downward movement of the forging part, the wedge-shaped top plate 113 connected to its front end will enter the rectangular slide groove 21 of the support platform 2, and the cooperation between the wedge-shaped top plate 113 and the rectangular slide groove 21 ensures that the forging part is always in the same vertical direction as the three U-shaped grooves 22 during the downward movement, thereby improving the stability of the forging work of the titanium alloy billet and avoiding the problem of dimensional deviation of the U-shaped half frame after forging due to the misalignment of the forging part and the U-shaped groove 22). During the deformation process, the lower end face of the titanium alloy billet is always in close contact with the upper surface of the T-shaped bearing block 261, and due to the continuous downward pressure of the forging part, the T-shaped bearing block 261 also slides synchronously along the inside of the U-shaped groove 22.

[0036] At the same time, when the titanium alloy billet is deformed and enters the U-shaped groove 22, due to the force on the middle part of the titanium alloy billet, its front and rear ends will synchronously tilt up to adapt to the deformation of the titanium alloy billet. When the two ends of the titanium alloy billet are gradually tilted up, the resistance of the rectangular plates 2321 on the front and rear sides gradually disappears, and then the rectangular plates 2321 on the front and rear sides are slowly reset by the tension of the spring, thereby ensuring that the push block 2322 is always close to the titanium alloy billet under the action of the spring force, and the friction between it and the titanium alloy billet is reduced by the roller shaft 2323 set on the end face of the push block 2322. At the same time, the rectangular plates 2321 on both sides and the push block 2322 are synchronously approached under the action of the spring reset force, which also avoids the vibration of the titanium alloy billet during forging.

[0037] It should be noted that when the forging part is gradually pressed downward to allow the titanium alloy billet to enter the U-shaped groove 22, the alignment plates 2312 located on the left and right sides of the titanium alloy billet always maintain close contact with the outer wall of the billet. The two alignment plates 2312 constrain the billet from the left and right directions, further preventing the billet from vibrating and displacing in different directions when subjected to forging pressure. At the same time, in conjunction with the work of the front and rear push blocks 2322, the titanium alloy billet can maintain a stable posture during the deformation process, ensuring that the metal flows along a predetermined path, thereby improving the accuracy and quality of forging.

[0038] As the forging gradually presses down to the bottom of the U-shaped groove 22, the excess heat generated during the forging process is discharged through the heat dissipation holes. During the sliding of the wedge-shaped top plate 113 along the rectangular chute 21, as its inclined section gradually fits with the wedge-shaped block 264, the wedge-shaped block 264 slides inside the support table 2 and pushes the V-shaped frame 263 to rotate. When the V-shaped frame 263 rotates around its center, its telescopic part gradually contacts the support table 2 and retracts, and the other end gradually moves and cooperates to be clamped into the mating groove of the clamping block 262, thus completing the locking work of the T-shaped bearing block 261 and the V-shaped frame 263. (In the initial state, the side of the V-shaped frame 263 close to the T-shaped bearing block 261 is parallel to the T-shaped bearing block 261. At this time, the T-shaped bearing block 261 is not blocked when sliding in the up and down direction. When the wedge-shaped block 264 is pushed by the wedge-shaped top plate 113, the wedge-shaped block 264 retracts along the support table 2 and pushes the V-shaped frame 263 to rotate. During the rotation of the V-shaped frame 263, the end close to the T-shaped bearing block 261 rotates and is clamped into the mating groove). Through the locking work of the V-shaped frame 263, the stable progress of the pressure holding work after the forging of the titanium alloy blank is ensured, and the T-shaped bearing block 261 is prevented from rebounding after being pressed, thereby avoiding damage to the lower surface of the U-shaped half-frame.

[0039] Unloading work of the U-shaped half-frame: After the pressure holding work of the U-shaped half-frame is completed, first control the hydraulic push rod 112 to drive the forging to retract. At this time, the wedge-shaped top plate 113 gradually disengages from the wedge-shaped block 264 during the retraction process. The wedge-shaped block 264 gradually resets due to the weakening of the pushing force and disengages from the V-shaped frame 263 during the reset process. When the force of the V-shaped frame 263 from the push of the wedge-shaped block 264 gradually decreases, the V-shaped frame 263 will gradually rotate and reset under the action of the torsion spring force and move away from the clamping block 262. Due to the disappearance of the pressing force above the clamping block 262, the T-shaped bearing block 261 gradually resets under the action of the spring force and pushes the U-shaped half-frame upward during the reset process, resulting in the upper and lower side walls of the U-shaped half-frame still being in close contact with the T-shaped bearing block 261 and the forging. The close contact between the T-shaped bearing block 261 and the forging improves the stability and coherence of the upward movement of the U-shaped half-frame during the unloading process.

[0040] At the same time, during the retraction of the hydraulic push rod 112, the drive motor drives the two threaded rods 241 to rotate in reverse. During the rotation of the two threaded rods 241, they respectively drive the corresponding synchronous pulleys 251 to rotate through the driving bevel gears 244 and the driven bevel gears 245, and then the mounting plates 2311 and the rectangular plates 2321 on both sides of the U-shaped groove 22 move away synchronously, thus completing the unloading work of the U-shaped half-frame.

[0041] It is worth emphasizing that the forging and forming equipment for the titanium alloy mobile phone frame with a microporous structure has the following advantages: Advantage 1: As the two L-shaped racks 243 continuously approach synchronously, after the front and rear thrust blocks 2322 complete the limiting work on the titanium alloy blank, the rectangular plates 2321 on both the front and rear sides will stop moving under the obstruction of the titanium alloy blank and fit against the outer wall of the titanium alloy blank. The single downward movement of the support bracket 111 completes the limiting work on the front and rear directions of the titanium alloy blank, preventing the titanium alloy blank from shifting in the front and rear directions before forging, thus avoiding deviations in the dimensions of the U-shaped half-frame after forging.

[0042] Advantage 2: When the two driven bevel gears 245 rotate, they respectively drive the three synchronous belt pulleys 251 on the same side through the synchronous belt 252. When the synchronous belt pulleys 251 in the middle and on the right side rotate, the waist-shaped plate one 2511 and the waist-shaped plate two 2512 hinged to their outer walls will respectively pull the mounting plates 2311 on both sides of the U-shaped groove 22 to approach synchronously. By setting the synchronous approach of the mounting plates 2311 on both sides of the U-shaped groove 22, the limiting work on the left and right directions of the titanium alloy blank is completed, ensuring that the distances between the two sides of the titanium alloy blank and the U-shaped groove 22 are the same before forging, guaranteeing the uniformity of the deformation of the titanium alloy blank during forging, and avoiding the problem of asymmetry of the U-shaped half-frame after forging caused by inconsistent distances on both sides.

[0043] Advantage 3: When the titanium alloy blank is placed above the U-shaped groove 22 and ready for forging and forming, the T-shaped bearing block 261 inside the U-shaped groove 22 will fit against the lower surface of the titanium alloy blank under the action of the spring. The provided T-shaped bearing block 261 provides effective support for the titanium alloy blank, preventing the blank from being affected by gravity due to being suspended below after preheating, and thus avoiding unnecessary deformation.

[0044] Advantage 4: When the forging gradually presses down and the titanium alloy blank enters the U-shaped groove 22, the alignment plates 2312 on both the left and right sides of the titanium alloy blank always keep in close contact with the outer wall of the blank. The two alignment plates 2312 constrain the blank from the left and right directions, effectively preventing the blank from vibrating and displacing in different directions under the action of the forging force. At the same time, cooperating with the work of the front and rear thrust blocks 2322, the titanium alloy blank can maintain a stable posture during the deformation process, ensuring that the metal flow proceeds along the predetermined path, thereby improving the precision and quality of forging and forming.

[0045] Advantage Five: During the retraction process, the wedge-shaped top plate 113 gradually disengages from the wedge-shaped block 264. Due to the weakening of the thrust force, the wedge-shaped block 264 gradually resets and disengages from the V-shaped frame 263 during the reset process. When the force from the wedge-shaped block 264 pushing against the V-shaped frame 263 gradually decreases, the V-shaped frame 263 will gradually rotate and reset under the action of the torsion spring force and move away from the clamping block 262. Due to the disappearance of the pressing force above the clamping block 262, the T-shaped bearing block 261 gradually resets under the action of the spring force and pushes the U-shaped half-frame upward during the reset process, causing the upper and lower side walls of the U-shaped half-frame to still be in close contact with the T-shaped bearing block 261 and the forging. The close contact between the T-shaped bearing block 261 and the forging improves the stability and continuity of the upward movement of the U-shaped half-frame during the blanking process.
