Description

Technical Field

[0001] This invention relates to the field of stamping technology, specifically to a stamping equipment for precision aluminum alloy forgings. Background Technology

[0002] Precision aluminum alloy forgings are complex-shaped, high-precision aluminum alloy forgings produced on forging equipment. Traditional aluminum alloy forging stamping processes typically employ a single-station stamping method, where all processes, including blank placement, stamping, and workpiece removal, are completed sequentially on a fixed die base. This process eliminates the need for cutting and machining. Generally, the raw material for precision aluminum alloy forgings is aluminum alloy sheet.

[0003] In practice, general stamping equipment can only use die stamping. However, in addition to using upper and lower dies for stamping, sometimes it is also necessary to emboss aluminum alloy forgings. In this case, using die stamping is obviously too costly, as a large amount of cost will be spent on die manufacturing. Generally, only one embossing head is used to emboss the aluminum alloy material. However, this equipment is usually two different machines from the die forging stamping equipment. The die forging stamping equipment does not have the function of fixing the workpiece, which increases the equipment footprint. Furthermore, since aluminum alloy sheets in practice are composed of different surfaces such as stepped or curved surfaces, the applicability of existing die forging stamping equipment is limited, and it cannot simultaneously meet the different stamping requirements of different aluminum alloy parts. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping equipment for precision aluminum alloy forgings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0012] As a further improvement of the present invention: the double-headed abutment part includes two sets of third electric telescopic frames fixedly connected to the sliding arm. The moving end of the third electric telescopic frame is fixedly connected to a linkage frame slidably connected to the support. The support is fixedly connected to four sets of rectangular sleeves arranged symmetrically. The rectangular sleeves are slidably connected to cross frames. The cross frames are hinged to the linkage frames through hinge plates. The two sets of cross frames are hinged to a set of guide frames. The guide frames are fixedly connected to cross rods. The sliding arm is fixedly connected to two sets of fourth electric telescopic frames. The moving end of the fourth electric telescopic frame is fixedly connected to a hollow sleeve slidably connected to the cross rods. The guide frames are fixedly connected to a second motor.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In operation, the hydraulic pressure structure connects to the upper mold body, placing the lower mold body on the support plane formed by the base and platform blocks. The lower mold body is then fixed to the mold connecting frame via bolts. The hydraulic pressure structure then moves the upper mold body, pressing it against the lower mold body to stamp the aluminum alloy sheet within the lower mold body. When surface embossing of the sheet-like aluminum alloy part is required, the first electric telescopic rod in each set of lower support structures drives the platform blocks to move, causing two sets of platform blocks within the same base to abut against each other. These abutting platform blocks form a support platform for the sheet-like aluminum alloy part. The first electric telescopic frame then extends, causing the V-shaped bracket to rise and apply pressure to the inclined plane. At this time, the V-shaped bracket presses against the platform blocks, causing them to squeeze together tightly, ensuring the stability of the support platform formed by the platform blocks. The aluminum alloy part is then placed on the platform blocks, and the machine moves symmetrically. The position of the rotating abutment and the double-headed abutment is adjusted, and the rotating abutment and the double-headed abutment apply pressure to the plate-shaped aluminum alloy part to limit its position. Then, the upper mold body is replaced with a stamping head (not shown in the figure). The hydraulic pressure structure performs the embossing operation on the aluminum alloy by driving the stamping head to apply pressure to the plate-shaped aluminum alloy part. If the aluminum alloy part has an arc surface structure, the first electric telescopic rod in each group of lower support structures drives the platform block to move into the seat body, and the first electric telescopic frame extends, causing the V-shaped bracket to rise. At this time, each group of V-shaped brackets moves to the same height, and the V-shaped brackets lift the aluminum alloy part. The symmetrical movement mechanism adjusts the position of the rotating abutment and the double-headed abutment, and the rotating abutment and the double-headed abutment apply pressure to the aluminum alloy part to limit its position. Then, the upper mold body is replaced with a stamping head, and the hydraulic pressure structure performs the embossing operation on the aluminum alloy by driving the stamping head to apply pressure to the aluminum alloy part. This invention achieves die forging and stamping of aluminum alloy parts through the cooperation of the lower support structure, the top pressure structure, and the hydraulic pressure structure. When it is necessary to stamp patterns on the surface of aluminum alloy parts, no additional equipment is required. This equipment can be used to complete the embossing of aluminum alloy parts, achieving multiple uses in one machine, saving space, and improving the applicability of this invention.

[0027] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0028] Example 1, see Figures 1 to 8 As shown, a precision aluminum alloy forging stamping equipment includes an outer frame 1, with sealing plates 2 installed at both ends of the outer frame 1. A controller is fixedly connected to the outer frame 1. The equipment also includes:

[0029] Multiple sets of lower support structures 3 are installed inside the outer frame 1. Each lower support structure 3 includes a seat 4 movably installed inside the outer frame 1. Two sets of mold connecting frames 57 are symmetrically arranged and fixedly installed at the top of the seat 4. A through groove is opened in the middle of the mold connecting frame 57. The two sets of lower support structures 3 abut against each other. Two sets of first electric telescopic rods 5 are symmetrically installed inside the seat 4. The moving end of the first electric telescopic rod 5 is fixedly connected to a platform block 6 that is slidably connected to the seat 4. An inclined surface 7 is provided at the bottom of the platform block 6. A first electric telescopic frame 8 is fixedly installed in the middle of the seat 4. A V-shaped bracket 9 is fixedly connected to the moving end of the first electric telescopic frame 8. The V-shaped bracket 9 is movably connected to the inclined surface 7 and is slidably installed inside the seat 4.

[0030] A top-pressing structure 10 connected to the outer frame 1 includes a symmetrical moving mechanism 11 installed on the outer wall of the outer frame 1. The symmetrical moving mechanism 11 is connected to two sets of symmetrically arranged rotating abutment parts 12. The rotating abutment parts 12 are connected to double-headed abutment parts 13 connected to the symmetrical moving mechanism 11.

[0031] A hydraulic pressure structure 14 connected to the outer frame 1 is used to connect and move the upper mold body 45 or the stamping head.

[0032] In use, the hydraulic pressure structure 14 connects to the upper mold body 45, placing the lower mold body 56 on the support plane formed by the base 4 and the platform block 6. The lower mold body 56 is then fixed to the mold connecting frame 57 by bolt fastening. The hydraulic pressure structure 14 then moves the upper mold body 45, pressing it against the lower mold body 56 to perform stamping operations on the aluminum alloy sheet in the lower mold body 56. When surface embossing of the plate-shaped aluminum alloy part is required, the lower support structures 3 in each group... The first electric telescopic rod 5 drives the platform block 6 to move, causing two sets of platform blocks 6 within the same body 4 to abut each other. This abutting platform block 6 forms a support platform for the plate-shaped aluminum alloy component. Then, the first electric telescopic frame 8 extends, causing the V-shaped bracket 9 to rise and apply pressure to the inclined surface 7. At this time, the V-shaped bracket 9 applies pressure to the platform block 6, causing the platform blocks 6 to press against each other, ensuring a tight abutment and guaranteeing the stability of the support platform formed by the platform blocks 6. Finally, the aluminum alloy component is placed on the platform block 6 and moved symmetrically. The moving mechanism 11 adjusts the position of the rotating abutment part 12 and the double-headed abutment part 13. The rotating abutment part 12 and the double-headed abutment part 13 apply pressure to the plate-shaped aluminum alloy part to limit its position. Then, the upper mold body 45 is replaced with a stamping head (not shown in the figure). The hydraulic pressure structure 14 performs embossing on the aluminum alloy by driving the stamping head to apply pressure to the plate-shaped aluminum alloy part. If the aluminum alloy part has an arc surface structure, the first electric telescopic rod 5 in each set of lower support structures 3 drives the platform block 6 to move into the seat body. In step 4, the first electric telescopic frame 8 extends, causing the V-shaped bracket 9 to rise. At this time, all sets of V-shaped brackets 9 move to the same height, supporting the aluminum alloy part. The symmetrical moving mechanism 11 adjusts the position of the rotating abutment part 12 and the double-headed abutment part 13, applying pressure to the aluminum alloy part to limit its movement. Then, the upper mold body 45 is replaced with a stamping head. The hydraulic pressure structure 14 performs embossing on the aluminum alloy part by driving the stamping head to apply pressure. This invention achieves die forging and stamping of aluminum alloy parts through the cooperation of the lower support structure 3, the top pressure structure 10, and the hydraulic pressure structure 14. When it is necessary to stamp patterns on the surface of aluminum alloy parts, no additional equipment is required; this equipment can be used to complete the embossing of aluminum alloy parts, achieving multiple uses in one machine, saving space, and improving the applicability of this invention.

[0033] In one embodiment, the symmetrical moving mechanism 11 includes a track 15 fixedly connected to the outer frame 1. A first dual-axis motor 16 is fixedly installed in the middle of the track 15. A first screw 17 is fixedly connected to the output end of the first dual-axis motor 16. The first screw 17 is threadedly connected to a sliding arm 18 that is slidably connected to the track 15. The rotating abutment part 12 and the double-headed abutment part 13 are both connected to the sliding arm 18. The first dual-axis motor 16 drives the first screw 17 to rotate. The two sets of first screws 17 respectively drive the two sets of sliding arms 18 to move along the track 15, thereby adjusting the distance between the two sets of sliding arms 18, and further adjusting the relative positions between the two sets of rotating abutment parts 12 and the two sets of double-headed abutment parts 13. This facilitates the adjustment of the limiting pressure position of the aluminum alloy part and provides space for the hydraulic pressure structure 14 to move towards the aluminum alloy part, avoiding motion interference between the rotating abutment part 12 and the double-headed abutment part 13 and the hydraulic pressure structure 14.

[0034] In one embodiment, the rotating abutment part 12 includes a bracket 19 fixedly connected to the sliding arm 18. The bracket 19 is fixedly connected to a second electric telescopic frame 20. The moving end of the second electric telescopic frame 20 is fixedly connected to a rotating limiting frame 21. A first motor 22 is fixedly installed on one side of the rotating limiting frame 21. The output shaft of the first motor 22 is fixedly connected to a double concave frame 23 rotatably connected to the rotating limiting frame 21. Arc-shaped blocks 24 and flat blocks 25 are respectively combined and connected at both ends of the double concave frame 23. The connection method between the double concave frame 23 and the arc-shaped blocks 24 and flat blocks 25 can be selected as snap-fit ​​or bolt connection. A slotted wheel 51 is fixedly installed on the other side of the rotating limiting frame 21. Two sets of slots 53 are symmetrically opened on the slotted wheel 51. A fifth electric telescopic frame 52 is fixedly connected to the rotating limiting frame 21. The moving end of the fifth electric telescopic frame 52 is fixedly connected to a pin block 54 movably connected to the slot 53. The pin block 54 is slidably connected to the rotating limiting frame 21. When the aluminum alloy part has an arc-shaped structure, the first motor 22 drives the double concave frame 23 to rotate, causing the arc-shaped block 24 mounted on the double concave frame 23 to approach the double concave frame 23. The position of the rotating abutment part 12 is adjusted by moving the bracket 19 via the sliding arm 18. Under the drive of the second electric telescopic frame 20 on the rotation limit frame 21, the first motor 22 drives the double concave frame 23 to move towards the aluminum alloy part, causing the arc-shaped block 24 to press down and fix the arc-shaped aluminum alloy part. When the aluminum alloy part has a plate-shaped structure, the first motor 22 drives the double concave frame 23 to rotate, causing the flat block 25 mounted on the double concave frame 23 to approach the double concave frame 23. The position of the rotating abutment part 12 is adjusted by moving the bracket 19 through the sliding arm 18. Under the drive of the second electric telescopic frame 20 to the rotating limit frame 21, the first motor 22 drives the double concave frame 23 to move towards the aluminum alloy part. The flat block 25 presses down to fix the plate-shaped aluminum alloy part. The platform block 6 supports the plate-shaped aluminum alloy part to limit its movement. This makes the rotating abutment part 12 suitable for limiting aluminum alloy parts with different structures. The fifth electric telescopic frame 52 limits the rotation of the slot wheel 51 by inserting the drive pin block 54 into the slot 53 to limit the rotation of the rotating limit frame 21.

[0035] In one embodiment, the double-headed abutment part 13 includes two sets of third electric telescopic frames 26 fixedly connected to the sliding arm 18. The moving end of each third electric telescopic frame 26 is fixedly connected to a linkage frame 27 slidably connected to the support 19. The support 19 is fixedly connected to four symmetrically arranged rectangular sleeves 28. Each rectangular sleeve 28 is slidably connected to a crossbeam 29. The crossbeam 29 is hinged to the linkage frame 27 via a hinge plate 30. Both sets of crossbeams 29 are hinged to a guide frame 31. The guide frame 31 is fixedly connected to a crossbar 32. The sliding arm 18 is fixedly connected to two sets of fourth electric telescopic frames 33. The movement of the fourth electric telescopic frames 33... A hollow sleeve 34 is fixedly connected to the end of the guide frame 31 and slidably connected to the crossbar 32. A second motor 35 is fixedly connected to the guide frame 31. A second screw 36 is fixedly connected to the output shaft of the second motor 35. A hanger 37 is threadedly connected to the second screw 36 and slidably connected to the guide frame 31. A second dual-output shaft motor 38 is fixedly connected to the hanger 37. A straight groove frame 55 is fixedly connected to the output end of the second dual-output shaft motor 38. A first pressure frame 39 is slidably connected to the straight groove frame 55. The first pressure frame 39 is slidably connected to the hanger 37. A second pressure frame 40 is fixedly connected to the hanger 37. The first pressure frame 39 is slidably connected to the second pressure frame 40.When the aluminum alloy part has an arc-shaped structure, the fourth electric telescopic frame 33 drives the hollow sleeve 34 to move, causing the hollow sleeve 34 to move the crossbar 32. The crossbar 32 drives the guide frame 31 to rotate, and the hanger 37 rotates with the guide frame 31, so that the first pressure frame 39 and the second pressure frame 40 point to the central axis of the arc-shaped aluminum alloy part. Under the drive of the second screw 36 by the second motor 35, the hanger 37 drives the second double-output shaft motor 38 to move, so that the first pressure frame 39 and the second pressure frame 40 both abut against the outer wall of the arc-shaped aluminum alloy part. When the aluminum alloy part has a plate-shaped structure, the fourth electric telescopic frame 33 drives the hollow sleeve 34 to move, causing the hollow sleeve 34 to move the crossbar 32. The crossbar 32 drives the guide frame 31 to rotate, and the hanger 37 rotates with the guide frame 31, adjusting the orientation of the first pressure frame 39 and the second pressure frame 40. The third electric telescopic frame 26 drives the linkage frame 27 to move, and the linkage frame 27 drives the hinge plate 30 to move. This causes the hinge plate 30 to drive the crossbeam 29 to move. Under the drive of the crossbeam 29 on the guide frame 31, the guide frame 31 moves to adjust the distance between the guide frames 31. Under the drive of the second motor 35 on the second screw 36, the hanger 37 presses down on the plate-shaped aluminum alloy part, so that the first pressure frame 39 and the second pressure frame 40 abut against the upper end surface of the plate-shaped aluminum alloy part, so that the double-headed abutment part 13 can limit and press the plate-shaped aluminum alloy parts of different widths. When the second dual-output shaft motor 38 drives the straight groove frame 55 to rotate, the straight groove frame 55 drives the first pressure frame 39 to move longitudinally, so that the first pressure frame 39 and the second pressure frame 40 are misaligned, so that the first pressure frame 39 and the second pressure frame 40 press against the top end surface of the plate-shaped aluminum alloy part at different heights, so that the double-headed abutment part 13 can easily press the stepped plane, and so that the double-headed abutment part 13 can easily fix and press aluminum alloy parts of different structures.

[0036] In one embodiment, the hydraulic pressure structure 14 includes a fixed arm 41 fixedly connected to the outer frame 1. A hydraulic cylinder 42 is fixedly connected to the fixed arm 41. A pressure sensor 43, communicatively connected to a controller, is fixedly connected to the moving end of the hydraulic cylinder 42. A mating sleeve 44 is fixedly connected to the pressure sensor 43. A linear displacement sensor 50 is connected to the mating sleeve 44 and the fixed arm 41. Multiple sets of locking elements 46 are threaded onto the mating sleeve 44, which restrict the movement of the upper mold body 45 or the stamping head. The hydraulic cylinder 42 moves the mating sleeve 44 via the pressure sensor 43, and the mating sleeve 44 moves the upper mold body 45 or the stamping head. During this process, the linear displacement sensor 50 continuously detects the movement distance of the mating sleeve 44.

[0037] In one embodiment, the locking member 46 includes a threaded rod 47 threadedly connected to the mating sleeve 44. The threaded rod 47 is fixedly connected to a rod body 48 and an anti-slip block 49. When it is necessary to replace the upper die body 45 or the stamping head, the threaded rod 47 is unscrewed from the mating sleeve 44 by rotating the anti-slip block 49, thereby releasing the rod body 48 from its restriction on the upper die body 45 or the stamping head, facilitating the replacement of the upper die body 45 or the stamping head.

[0038] Example 2, based on Example 1, see [link / reference] Figure 1 and Figure 2 The sealing plate 2 is connected to the outer frame 1 by multiple sets of screws. Openings are provided at both ends of the outer frame 1 where it contacts the sealing plate 2. The two sets of sealing plates 2 respectively abut against the seat bodies 4 arranged at both ends of the same row of seat bodies 4. By disassembling the sealing plate 2, the obstruction of the openings is removed, allowing the lower support structure 3 to be disassembled from the openings, thus facilitating disassembly and maintenance of the lower support structure 3.
