Description

Technical Field

[0001] This invention relates to the field of shaping technology, and more specifically to an automated device for shaping the appearance of hemispherical platinum crucibles. Background Technology

[0002] After being repeatedly rolled by a roller press, the metal sheet is formed into thin sheets with a length and width of 300*270mm and a thickness of 0.1mm. The formed sheet is then stamped into a hemispherical thin-walled part using a spherical die. Since the product thickness is only 0.1mm, it has been verified through experiments that it cannot be stretched (the thin-walled part will break after stretching), so only the stamping process can be used. However, when the flat sheet is extruded into a hemispherical shape, many irregular wrinkles will be generated on the spherical surface. These wrinkles cannot be eliminated during the stamping process. Therefore, the traditional method mainly relies on manual tapping of the spherical surface with a plastic rod to try to smooth out the wrinkles, but the hands cannot withstand prolonged tapping. Mechanical equipment is also used for shaping, but existing equipment can only process products of a single diameter, making it impractical, and the use of only a single tapping rod results in low shaping efficiency. Therefore, an automated device for shaping the appearance of hemispherical platinum crucibles is designed. Summary of the Invention

[0003] The purpose of this invention is to provide an automated device for shaping the appearance of hemispherical platinum crucibles, thereby solving the above-mentioned technical problems.

The swing assembly includes a first swing arm and a second swing arm that are set at an angle to each other and rotate synchronously; Two striking components are respectively mounted on the first swing arm and the second swing arm. The first swing arm and the second swing arm drive the striking components to swing back and forth within a set angle, so that the striking components strike the surface of the hemispherical crucible.

[0013] As a further aspect of the present invention: the striking assembly includes a striking cylinder and a striking rod mounted on the piston rod of the striking cylinder, thereby realizing the reciprocating extension and retraction motion of the striking rod.

[0014] As a further aspect of the present invention, the installation position of the striking cylinder can be adjusted up and down to accommodate hemispherical crucibles of different diameters.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-2 As shown, the present invention is an automated device for shaping the appearance of a hemispherical platinum crucible, including a frame 1, on which a rotating assembly 2 is rotatably mounted. The rotating assembly 2 includes a mold support plate 25 and a rotation drive device. The mold support plate 25 is used to support the hemispherical crucible, and the rotation drive device drives the mold support plate 25 to rotate intermittently. A swing assembly 3 is installed on the frame 1 and on one side of the rotating assembly 2. It includes a first swing arm and a second swing arm that are set at an angle to each other and rotate synchronously. A striking assembly 4 is provided on both the first swing arm and the second swing arm. The first swing arm and the second swing arm drive the striking assembly 4 to swing back and forth within a set angle, so that the striking assembly 4 strikes the surface of the hemispherical crucible.

[0026] In this embodiment, the specific workflow is as follows: A hemispherical platinum crucible is inverted onto a mold support plate 25. The crucible surface is shaped by simulating hand tapping. The angle between the two sets of tapping components 4 is adjusted by the first and second swing arms, and then the tapping components 4 tap the wrinkled areas on the surface of the hemispherical platinum crucible. During the tapping process, the mold support plate 25 is rotated by a rotary drive device, which in turn causes the hemispherical platinum crucible to rotate intermittently, achieving comprehensive tapping of the hemispherical platinum crucible. This process repairs the wrinkles on the surface of the hemispherical platinum crucible. This structure replaces manual operation, reduces labor, achieves automated processing, and improves work efficiency.

[0027] It should be noted that during the striking process, the striking surface of the striking component 4 should always face the center of the hemispherical platinum crucible, so that the striking surface remains tangent to the surface of the hemispherical platinum crucible when it is in contact with it. This ensures that the striking force of the striking component 4 can be applied perpendicularly to the surface of the hemispherical platinum crucible, avoiding the generation of component forces that could tear the hemispherical platinum crucible and cause damage. At the same time, the striking time is reduced by more than half by using two swing arms at an angle to each other to strike synchronously.

[0028] In this embodiment, refer to Figure 1-3As shown: A rotating assembly 2 is arranged below the hemispherical platinum crucible. The rotating assembly 2 includes a bearing mounting plate 24, a connecting plate 23 fixedly mounted on the bottom of the bearing mounting plate 24, a motor mounting plate 22 fixedly mounted on the bottom of the connecting plate 23, and a rotary motor 21 fixedly mounted on the bottom of the motor mounting plate 22. The output shaft of the rotary motor 21 is connected to a rotating shaft 26 via a coupling 27. The rotating shaft 26 passes through the bearing mounting plate 24 and is fixedly connected to a mold support plate 25. A bearing is provided at the connection between the rotating shaft 26 and the bearing mounting plate 24. By starting the rotary motor 21, the mold support plate 25 is driven to rotate, thereby driving the hemispherical platinum crucible to rotate, achieving full coverage hammering. In this embodiment, the rotating component 2 can also drive the mold support plate 25 to rotate by means of gear and rack transmission.

[0029] In this embodiment, refer to Figure 5 As shown, the bearing mounting plate 24 is driven to slide horizontally by the transfer mechanism 6, and the mold support plate 25 is transferred between the loading station and the striking station by the horizontal sliding of the bearing mounting plate 24. The transfer mechanism 6 includes two linear guide rails 63 symmetrically mounted on the surface of the frame 1. The bearing mounting plate 24 slides on the linear guide rails 63. A push cylinder parallel to the linear guide rails 63 is fixedly mounted at the bottom of the surface of the frame 1. The piston rod of the push cylinder is fixedly connected to a connecting plate 23, thereby pushing the connecting plate 23 through the push cylinder, causing the bearing mounting plate 24 to slide on the linear guide rails 63, completing the conversion between the loading station and the striking station. Figure 1 For example, when the bearing mounting plate 24 moves to the leftmost position, the loading and unloading of materials is achieved; when it moves to the rightmost position, the material is tapped using the tapping component 4. The entire process is automated.

[0030] See Figure 5 As shown, the frame 1 has a groove 11, which is used for the movement of part of the rotating component 2 to avoid interference problems.

[0031] See Figure 4 As shown, the transfer mechanism 6 also includes a buffer support 62 and a hydraulic buffer 61 mounted thereon; the hydraulic buffer 61 buffers the bearing mounting plate 24 that is being transported.

[0032] In this embodiment, refer to Figure 4As shown, the swing assembly 3 includes a servo motor assembly 35 fixedly mounted on the frame 1. The servo motor assembly 35 consists of a servo motor, a reducer, a coupling, and a transmission shaft. Both the first and second swing arms include a main swing arm 31 and a secondary swing arm 32 arranged in parallel. Both the main swing arm 31 and the secondary swing arm 32 are sleeved on the transmission shaft. The main swing arm 31 is connected to the secondary swing arm 32 via two parallel swing arm connecting rods 33. The swing arm connecting rods 33 are perpendicular to the main swing arm 31 and the secondary swing arm 32. One end of the swing arm connecting rod 33 is fixed to the secondary swing arm 32, and the other end... The secondary swing arms 32 are connected; two secondary swing arms 32 are located in the middle of the drive shaft, while two main swing arms 31 are located at the ends of the drive shaft. A bolt is installed at the end of the drive shaft to lock the two main swing arms 31. At this time, the secondary swing arms 32 can also be limited and fixed by the action of the swing arm connecting rod 33. Then, the servo motor is started, which drives the drive shaft to rotate, and at the same time, drives the main swing arms 31 and secondary swing arms 32 to rotate. The rotation of the servo motor drives the swing arms to rotate accordingly, so that the striking rod 43 can strike along the arc surface of the product, and in order to improve production efficiency.

[0033] The swing assembly 3 also includes a swing arm adjusting ring 34, which has two symmetrical swing arm grooves 36, as shown in the appendix. Figure 4 As shown, the two swing arm grooves 36 are offset on the two sides of the swing arm adjusting ring 34; the swing arm grooves 36 are equipped with locking bolts. When adjusting the included angle of the two auxiliary swing arms 32, the bolts at the end of the drive shaft are first loosened, and then the first and second swing arms are manually rotated. The two auxiliary swing arms 32 slide on the surface of the swing arm grooves 36. After the included angle is adjusted, the auxiliary swing arms 32 are locked by locking bolts, and the bolts at the end of the drive shaft are locked.

[0034] By integrating the swing arm adjusting ring 34, the first swing arm, and the second swing arm into a single unit, the stability of the swing arms is enhanced, their coordination is improved, and their linkage is made more efficient, making operation more convenient. The angle between the two swing arms can be adjusted according to the actual folding conditions using the arc-shaped swing arm adjusting ring 34 located at the rear of the swing arms.

[0035] A proximity switch 8 is provided on one side of the swing component 3 for resetting the origin and limiting the swing component 3, so as to prevent collision accidents when the servo swing angle is set incorrectly.

[0036] In this embodiment, the striking assembly 4 includes a cylinder mounting plate 42 fixedly installed at the end of the swing arm connecting rod 33 and perpendicular to it. A striking cylinder 41 is arranged parallel to the cylinder mounting plate 42, and a striking rod 43 is provided on the piston rod of the striking cylinder 41. This enables the striking rod 43 to reciprocate and extend, cyclically striking the surface of the hemispherical crucible. The installation position of the striking cylinder 41 can be adjusted vertically to accommodate hemispherical crucibles of different diameters. Adjusting the vertical position of the striking cylinder 41 causes the cylinder to be adjusted upwards for larger diameter crucibles and downwards for smaller diameter crucibles.

[0037] In this embodiment, a positioning component 7 is provided on the frame 1 corresponding to the swing component 3. The positioning component 7 includes a rotary cylinder support frame 74 fixed on the frame 1. A rotary cylinder 75 is fixedly installed on the rotary cylinder support frame 74. A rotary cylinder swing arm 76 is installed on the rotary cylinder 75 for moving the pen-shaped cylinder 78 directly above the mold support plate 25. The piston rod of the pen-shaped cylinder 78 extends downward and is connected to a pressure ring 77 through a bearing to press the top of the hemispherical crucible during impact and allow it to rotate with the mold support plate 25. This mechanism uses a pen-shaped cylinder 78 with a pressure ring 77 to press the product from the top to prevent the product from moving. Since the product is constantly rotating with the mold, a bearing is installed on the pressure ring 77 so that the pressure block can rotate with the product during the pressing process.

[0038] The positioning assembly 7 also includes a push cylinder mounting plate 71 fixedly mounted on the frame 1. A push cylinder 72 is fixedly mounted on the top of the push cylinder mounting plate 71, and a positioning block 73 is fixedly mounted on the piston rod of the push cylinder 72. The push cylinder 72 drives the positioning block 73 to insert into or disengage from the bearing mounting plate 24 to position the bearing mounting plate 24 at the striking station. The striking process will generate large vibrations, and the positioning assembly 7 can prevent the mold from shifting.

[0039] In this embodiment, product stretching mechanisms 5 are symmetrically installed on both sides of the linear guide rail 63 on the frame 1. The product stretching mechanism 5 includes a stretching cylinder mounting plate 53. A vertically arranged stretching cylinder 54 is fixedly installed on the stretching cylinder mounting plate 53. A dual-axis cylinder mounting plate 55 is fixedly installed on the piston rod of the stretching cylinder 54. A horizontally arranged dual-axis cylinder 52 is fixedly installed on the dual-axis cylinder mounting plate 55. An arc-shaped clamping block 51 is fixedly installed on the piston rod of the dual-axis cylinder 52. The dual-axis cylinder 52 drives the arc-shaped clamping block 51 to press against the side wall of the hemispherical crucible in the middle. Then, the stretching cylinder 54 drives the dual-axis cylinder 52 to move downward, so that the crucible is in contact with the mold support plate 25.

[0040] The working process in this embodiment is as follows: Taking a hemispherical platinum crucible with an R75 thickness of 0.1mm as an example, the location and size of the wrinkles in the product are not fixed, so it can only be tapped to cover the entire surface (Note: after the crucible is stamped, there will be some areas on the top without any wrinkles, so the top does not need to be tapped). After the equipment is started, all mechanisms and cylinders are in their initial positions, such as Figure 1 As shown in the diagram; first, the product is placed upside down on the mold support plate 25. After the equipment is started, the dual-axis cylinders 52 on both sides drive the arc-shaped clamping blocks 51 to clamp the product. Then, the lower tension cylinder 54 descends, allowing the crucible to fit more closely with the mold support plate 25. Next, the dual-axis cylinders 52 on both sides loosen, and the entire transfer mechanism 6 prepares to move to the striking position. The lower cylinder pulls the transfer mechanism to the striking position. After the cylinder moves into place, the side push cylinder 72 pushes out. Insert the positioning block 73 into the positioning groove on the bearing mounting plate 24. Meanwhile, the upper rotary cylinder 75 drives the rotary cylinder swing arm 76 to rotate directly above the product. Then, the pen-shaped cylinder 78 on the rotary cylinder swing arm 76 descends, causing the pressure ring 77 to press against the product. Next, the two striking cylinders 41 on the main swing arm 31 start working. During the striking process, the servo motor controlling the two swing arms first controls the swing arms to move to the left. After each swing cycle, the lower rotary motor 21 controls the mold support plate 25 to rotate at a certain angle. Then, the swing arms swing in the opposite direction, repeating the swinging and striking operations in sequence. Finally, after the crucible surface is struck, all the cylinders return to their initial positions. At this time, the lower cylinder pulls the transfer mechanism 6 to move to the material picking position. Finally, the employee removes the product and places a new product, repeating the above operations in sequence.

[0041] Example 2 Based on Embodiment 1, the included angle between the first and second swing arms is 90 degrees. The rotation angle of the mold support plate 25 needs to be stable each time, neither too large nor too small. If the angle is too large, the impact will not be in place; if the angle is too small, the overall time will be too long. Therefore, the angle of intermittent rotation of the mold support plate 25 each time is 3 degrees. By using two swing arms to strike simultaneously, with the two swing arms forming an included angle of approximately 90 degrees, the motor controlling the rotation only needs to rotate 90 degrees in one direction each time. After each 90-degree rotation of the motor, the rotary motor of the transfer mechanism 6 below controls the mold support plate 25 to rotate 3 degrees. Then, the servo motor behind controls the swing arms to rotate 90 degrees in the opposite direction, and so on, to strike the spherical surface of the crucible, reducing the striking time by more than half.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
