Description

Technical Field

[0001] This invention relates to the field of hydraulic shaping technology, specifically to a dual-cylinder hydraulic shaping device. Background Technology

[0002] Hydraulic forming equipment is an industrial device that uses hydrostatic pressure to shape, straighten, or press-fit materials such as metals and plastics. Its working principle is based on Pascal's law; the high pressure generated by the hydraulic system drives the actuator to apply precise force to the workpiece, thereby achieving the forming process. Depending on their structural form, hydraulic forming equipment can be divided into single-cylinder, double-cylinder, and multi-cylinder types. Among them, the double-cylinder structure is particularly outstanding in workpiece processing due to its symmetry and stability.

[0003] However, in existing dual-cylinder hydraulic forming equipment, the feeding process generally relies on manual operation. Operators must manually move the materials to be processed and place them in the designated position on the lower mold, which presents several problems. First, manual feeding is inefficient, becoming a bottleneck restricting the improvement of the overall production line's cycle time and failing to meet the demands of modern high-speed production. Second, repetitive physical handling not only increases the labor intensity of workers and easily leads to fatigue, but also poses significant safety hazards due to the potential risks in the equipment's mold closing and pressurized forming processes, requiring direct manual intervention.

[0004] Therefore, how to provide a dual-cylinder hydraulic shaping device that overcomes the shortcomings of existing technologies is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0058] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0059] Please refer to Figures 1-9 The dual-cylinder hydraulic shaping device disclosed in this invention will now be described. This invention consists of seven parts, as follows: Figure 1 , Figure 2 , Figure 3 As shown, the assembly includes a base 1, a pneumatic-hydraulic booster cylinder 3, a material support frame 6, a guide rail assembly 7, a drive assembly 8, a feeding assembly 9, and a release assembly 10. The base 1 is fixedly installed on the ground, and a lower template 2 is installed on the top of the base 1. The pneumatic-hydraulic booster cylinder 3 is located above the base 1, and a top plate 4 is installed at the output end of the pneumatic-hydraulic booster cylinder 3. An upper template 5 is installed at the bottom of the top plate 4. The material support frame 6 is fixedly installed on the ground, the guide rail assembly 7 is installed on the top of the base 1, the drive assembly 8 is located between the base 1 and the top plate 4, the feeding assembly 9 is installed on the drive assembly 8, and the release assembly 10 is installed on the side wall of the lower template 2.

[0060] In this embodiment, the bottom of the base 1 is provided with height-adjustable support legs. The base 1 is fixedly installed on the ground and leveled by the support legs. This application is a hydraulic shaping device with a dual-cylinder structure, therefore there are two pneumatic-hydraulic booster cylinders 3. As is common knowledge in the art, a mounting plate or gantry frame or other mounting structure is usually provided above the pneumatic-hydraulic booster cylinders 3 for installation. The pneumatic-hydraulic booster cylinders 3 are fixedly installed on the mounting structure, and the user can adjust them according to the site requirements. Therefore, the upper mounting structure is not shown in this application. The material support rack 6 is used to place the material to be processed; the guide rail assembly 7 is used to support the material to be processed; the feeding assembly 9 is used to drive the material to the lower template 2; the drive assembly 8 is used to provide power to the feeding assembly 9; the detachment assembly 10 is used to detach the feeding assembly 9 from the material when the feeding assembly 9 delivers the material to the position of the lower template 2.

[0061] In this application, the pneumatic-hydraulic booster cylinder 3 is activated, driving the top plate 4 to move the upper mold plate 5 downwards. During this process, the drive assembly 8 converts the linear motion of the top plate 4 into horizontal linear motion, and transports the material above the lower mold plate 2 through the feeding assembly 9, guide rail assembly 7, and release assembly 10. During the closing process of the upper mold plate 5 and the lower mold plate 2, the required forming pressure is applied to the material, causing it to deform in the sealed cavity and achieve precision forming. After forming is completed, the upper mold plate 5 rises, and the drive assembly 8 can drive the feeding assembly 9 back to the material support 6, ready to feed the next material. The processed material is removed by equipment or manual labor in subsequent processes.

[0062] By setting up the drive assembly 8 and the feeding assembly 9, the vertical movement of the upper mold plate 5 driven by the pneumatic-hydraulic booster cylinder 3 is converted into the horizontal feeding movement of the feeding assembly 9. This eliminates the need for an additional motor or power source, achieving material conveying and positioning, replacing inefficient and cumbersome manual feeding, improving production efficiency, and perfectly matching the equipment's own working rhythm. The guide rail assembly 7 provides a smooth and unobstructed transmission path for the material, effectively preventing jamming or damage. The release assembly 10 implements a dynamic unhooking mechanism, allowing the material to be released at the appropriate position, avoiding interference during mold closing.

[0063] like Figure 3 , Figure 4 , Figure 8 As shown, the material support frame 6 includes a material support half frame 61, a feed inlet 62 and a discharge outlet 63. The material support half frames 61 are arranged in pairs, and the two material support half frames 61 are symmetrically arranged with respect to the lower template 2. The feed inlet 62 is opened on the top of the material support half frame 61, and the discharge outlet 63 is opened on the side wall of the material support half frame 61 near the base 1.

[0064] Structure of material rack 6 Figure 3 , Figure 8As shown, the material support frame 6 consists of two material support halves 61. Each material support half 61 has a mounting bracket at its bottom for stable connection with the ground. There is a certain gap between the two material support halves 61. This gap should be greater than the length of the lower template 2. This design is to leave enough space for the feeding component 9 and the driving component 8. The material in this application will be greater than the length of the lower template 2. After forming, the material will enter the cutting process to remove the excess material.

[0065] The shape of the discharge port 63 is as follows Figure 4 As shown, preferably, the height of the discharge port 63 is approximately 1.3 times the thickness of a single material. The design of the discharge port 63 ensures that after the bottom material is removed, the material above will fall accurately, ready for the next material removal.

[0066] like Figure 5 , Figure 6 As shown, the guide rail assembly 7 includes a fixed guide rail 71, a guide rail seat 72, a floating guide rail 73, and a guide rail spring 74, which are symmetrically arranged about the lower template 2. The fixed guide rail 71 is installed on the top of the base 1, the guide rail seat 72 is installed on the top of the base 1, the floating guide rail 73 is slidably connected to the top of the guide rail seat 72, one end of the guide rail spring 74 is connected to the top of the guide rail seat 72, and the other end of the guide rail spring 74 is connected to the bottom of the floating guide rail 73.

[0067] The structure and placement of the floating guide rail 73 are as follows: Figure 5 As shown, the fixed guide rail 71 and the floating guide rail 73 provide support and guidance for the material. The length of the floating guide rail 73 is slightly greater than the width of the lower template 2, and together with the fixed guide rail 71, they form a guide channel, ensuring that the material can accurately reach the predetermined position of the lower template 2. When the upper template 5 is pressed down, the floating guide rail 73 can descend with the material without interfering with the movement of the upper template 5, ensuring that the material can be precisely formed.

[0068] It is worth noting that, to avoid interference as the material travels along the fixed guide rail 71 and floating guide rail 73 to the top of the lower template 2, the material should not contact the edge or sidewall of the lower template 2 during the feeding process. Therefore, regardless of whether there is material on top of the floating guide rail 73, the top surface height of the floating guide rail 73 should be slightly higher than the height of the lower template 2. The top surface height of the fixed guide rail 71 can be flush with or slightly higher than the top surface height of the floating guide rail 73, and the bottom surface height of the discharge port 63 can be flush with or slightly higher than the top surface height of the fixed guide rail 71. When the dimensional accuracy of the material is high, having the top surface heights of the fixed guide rail 71, the floating guide rail 73, and the bottom surface height of the discharge port 63 flush will not affect the material conveying. When the dimensional accuracy of the material is low, the height difference forms a stepped structure, which can help the material pass smoothly.

[0069] like Figure 5 , Figure 6 As shown, the drive assembly 8 includes a linear guide rail 81, a first rack 83, a second rack 84, a bearing seat 85, a first gear 87, and a second gear 88, all symmetrically arranged about the lower template 2. The linear guide rail 81 is mounted on the top of the base 1, and a slide table 82 is slidably connected to the top of the linear guide rail 81. The first rack 83 is vertically arranged and mounted on the side wall of the top plate 4. The second rack 84 is horizontally arranged and mounted on the top of the slide table 82. The bearing seat 85 is mounted on the side wall of the base 1, and a shaft 86 is rotatably connected inside the bearing seat 85. The first gear 87 is mounted on one end of the shaft 86 and meshes with the first rack 83. The second gear 88 is mounted on the other end of the shaft 86 and meshes with the second rack 84.

[0070] In this embodiment, the first rack 83 is mounted on the side wall of the top plate 4. During installation, care must be taken to ensure that the first rack 83 avoids the base 1 during descent. The linear guide rail 81 and the slide table 82 make the movement of the second rack 84 smoother. The first gear 87 and the second gear 88 are respectively located at both ends of the shaft 86 and are on the same axis.

[0071] By configuring the first rack 83, the second rack 84, the bearing housing 85, the first gear 87, and the second gear 88, the linear motion of the top plate 4 is converted into horizontal linear motion. The power transmission path is clear, and the mechanical structure is simple and reliable. The drive assembly 8 is integrated into the equipment, eliminating the need for a complex independent control system. This not only saves installation space and reduces manufacturing costs and maintenance difficulty but also improves the integration and reliability of the entire system.

[0072] It is worth noting that during the process from the descent of the upper mold plate 5 until it cooperates with the lower mold plate 2 to complete the mold closing, the second rack 84 should drive the feeding assembly 9 to transport the material in the material holder 6 through the guide rail assembly 7 to the preset position above the lower mold plate 2. This requires adjusting the relationship between the stroke of the upper mold plate 5 and the second rack 84. Since the angular velocities of the first gear 87 and the second gear 88 are the same, adjusting the diameters of the first gear 87 and the second gear 88 can make their linear velocities change proportionally, thereby adjusting the relationship between the stroke of the upper mold plate 5 and the second rack 84. This allows the second rack 84 to drive the feeding assembly 9 to transport the material to the preset position above the lower mold plate 2 when the upper mold plate 5 descends; and the second rack 84 to drive the feeding assembly 9 back to the starting position and prepare to pick up the material again when the upper mold plate 5 rises.

[0073] like Figure 4 , Figure 7As shown, the feeding assembly 9 includes a moving block 91, a movable pull block 94, and a feeding spring 96. The moving block 91 is mounted on the side wall of the second rack 84. A receiving groove 92 is formed on the top of the moving block 91, and a sliding groove 93 is formed on the inner side wall of the receiving groove 92. A sliding column 95 is formed on the outer side wall of the movable pull block 94. The movable pull block 94 is slidably connected to the receiving groove 92 through the sliding groove 93. One end of the feeding spring 96 is connected to the bottom wall of the receiving groove 92, and the other end of the feeding spring 96 is connected to the bottom of the movable pull block 94. Preferably, the top of the movable pull block 94 has a driving inclined surface 941 that gradually slopes downward in the direction away from the lower template 2.

[0074] It is worth noting that the height of the moving block 91 should be lower than the top surface height of the lower template 2. Its height setting is to avoid interference with the upper template 5 during the descent of the upper template 5.

[0075] The structure of the receiving groove 92, the sliding groove 93 and the movable pull block 94 is as follows Figure 7 As shown, the movable pull block 94 can extend and retract within the receiving groove 92. When the movable pull block 94 extends, its height is higher than the bottom surface of the lowest material in the material support frame 6 but lower than the top surface of the lowest material, allowing it to pull the lowest material. The movable pull block 94 at the top of the moving block 91 and the discharge port 63 of the material support frame 6 form a dynamic pushing path. With the support and guidance of the fixed guide rail 71 and the floating guide rail 73, the material is automatically conveyed from the feed port 62 to the lower template 2 under the drive of the drive component 8.

[0076] The setting position of the drive ramp 941 is as follows Figure 7 As shown. In use, after one mold closing is completed, the top plate 4 rises, and the second rack 84 drives the moving block 91 back to the starting position. During this process, when the driving inclined surface 941 at the top of the movable pull block 94 contacts the lowest material in the material support frame 6, the movable pull block 94 will move downward into the receiving groove 92 and compress the feeding spring 96. After the movable pull block 94 has completely passed under the material, the feeding spring 96 will return to its original deformation and push the movable pull block 94 out of the receiving groove 92, ready to start the next pushing procedure.

[0077] like Figure 1 , Figure 5 , Figure 9 As shown, the loosening assembly 10 includes a rotating wheel 101 and a guide block 102. The rotating wheels 101 are arranged in pairs and rotatably connected to the side wall of the movable pull block 94. The guide block 102 is disposed on the side wall of the lower template 2. When the movable pull block 94 moves to the position of the guide block 102, the guide block 102 can drive the movable pull block 94 into the receiving groove 92. Figure 9As shown, the guide block 102 includes a fixing part 1021 and a guide part 1022. The fixing part 1021 is disposed on the side wall of the lower template 2. The guide parts 1022 are arranged in pairs and disposed on the side wall of the fixing part 1021. A guide slope 1023 is formed at the end of the guide part 1022.

[0078] The shape and position of the rotating wheel 101 and the guide block 102 are as follows: Figure 9 As shown. The guide section 1022 has a trapezoidal structure. When the guide slope 1023 contacts the rotating wheel 101, it can drive the movable pull block 94 to retract into the receiving groove 92. As the movable pull block 94 continues to move, the rotating wheel 101 will move to the bottom of the guide section 1022. The bottom surface of the guide section 1022 is a plane, which can keep the movable pull block 94 in a stable retracted state during this stage.

[0079] By setting the position of the guide block 102, the release position of the material can be controlled, ensuring accurate material positioning during mold closing. Since there is a cutting process after material shaping, the area of ​​the material can be slightly larger than the area of ​​the lower mold plate 2, so the release position of the material does not need to be too precise.

[0080] During the feeding process, the movable pull block 94 should place the material above the floating guide rail 73. At this time, the material should be fixed in position and wait for the upper mold plate 5 to descend and close the mold. This requires the material to be released automatically at the end of the feeding stroke. The guide slope 1023 of the guide block 102 and the roller 101 on the side wall of the movable pull block 94 form a dynamic disengagement mechanism. When the movable pull block 94 moves to the side of the lower mold plate 2, the guide block 102 drives the movable pull block 94 to retract into the receiving groove 92, avoiding interference between the movable pull block 94 and the upper mold plate 5 during mold closing. This process does not require sensor or electronic control intervention; the purely mechanical operation ensures the accuracy and consistency of the action.

[0081] It is worth noting that during the mold closing process of the upper mold plate 5 and the lower mold plate 2, the second rack 84 will continue to drive the moving block 91 to move. Since the second rack 84 and the moving block 91 are rigidly connected, in order to avoid interference, the length of the second rack 84 should allow the moving block 91 to continue to move a certain distance during the mold closing process, and the length of the guide part 1022 should be related to this distance to ensure that within this distance, the guide part 1022 can always drive the movable pull block 94 to retract into the receiving groove 92.

[0082] The usage process of this invention embodiment is as follows:

[0083] First, the material to be processed is placed in the material rack 6. The pneumatic-hydraulic booster cylinder 3 starts the top plate 4 to descend. The first rack 83 on the side wall of the top plate 4 will drive the second rack 84 and the slide table 82 to move along the linear guide rail 81 through the first gear 87 and the second gear 88. As the second rack 84 moves, the movable pull block 94 on the moving block 91 will pull the material in the material rack 6 from the discharge port 63 to the lower template 2 along the fixed guide rail 71 and the floating guide rail 73. After the material is completely separated from the material rack 6, the material above will fall to the bottom of the material rack 6.

[0084] Secondly, when the movable pull block 94 moves to the position of the guide block 102, the guide slope 1023 contacts the rotating wheel 101, causing the movable pull block 94 to retract into the receiving groove 92 and release the material. At this time, the material will remain stationary on the top of the floating guide rail 73 above the lower mold plate 2. The upper mold plate 5 continues to descend. After the upper mold plate 5 contacts the material, it will press the material onto the top surface of the lower mold plate 2 and begin to close the mold. At this time, the floating guide rail 73 descends along with the material.

[0085] Secondly, as the upper mold plate 5 continues to descend after mold closing, the second rack 84 will continue to drive the moving block 91 to move. As the moving block 91 continues to move, the rotating wheel 101 will move to the bottom of the guide part 1022 and move along the bottom of the guide part 1022, keeping the movable pull block 94 in the retracted state until the mold closing is completed.

[0086] Finally, after one mold closing is completed, the top plate 4 rises, and the second rack 84 drives the moving block 91 back to the starting position. During this process, when the driving inclined surface 941 at the top of the movable pull block 94 contacts the lowest material in the material support frame 6, the movable pull block 94 will move downward into the receiving groove 92 and compress the feeding spring 96. After the movable pull block 94 has completely passed under the material, the feeding spring 96 will return to its original deformation and push the movable pull block 94 out of the receiving groove 92.

[0087] Repeating the above steps allows for the continuous completion of the shaping process from material loading to mold closing.

[0088] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
