Technical Field
[0001] This utility model relates to the field of aluminum plate processing technology, specifically to a curved aluminum single-panel processing and correction device. Background Technology
[0002] Curved aluminum panel processing and correction equipment is a special equipment used to reprocess and correct flat aluminum materials or irregularly shaped aluminum panels that have defects such as springback, twisting, and edge wavy into single-curved or double-curved aluminum panels that meet the design curvature requirements through pressing. This type of equipment has wide applications in metal curtain walls, architectural decoration and other fields.
[0003] However, the current common processing method relies on prefabricated upper and lower molds, which are used to press and shape or correct the aluminum plate in one go. Although this traditional method is more efficient when mass-producing products with a single curvature, it is necessary to replace other corresponding molds when facing the production needs of multiple varieties, small batches or frequent changes in curvature. The mold replacement process is cumbersome, time-consuming, inconvenient, and costly. Therefore, in view of the above problems, a curved aluminum single panel processing and correction equipment is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a curved aluminum panel processing and correction device to solve the problems of inconvenience in changing molds and high cost when the existing curved aluminum panel processing and correction devices are used to process and correct aluminum panels with different curvatures.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A curved aluminum single-panel processing and correction device includes a main frame. The main frame includes a pair of symmetrically arranged bases. Several guide posts are fixedly connected between the corners of the facing surfaces of the upper and lower bases. An electric push rod is fixedly connected to the upper end face of the upper base. The drive rod of the electric push rod passes through the upper base and is fixedly connected to a top plate. The top plate is slidably connected to each guide post. A pair of symmetrically arranged contour shaping modules are installed on the lower end face of the top plate and the upper end face of the lower base. The contour shaping module includes a housing. An electrically controlled valve pipe is fixedly connected to the left side of each housing in a communicating manner. The housing is located away from the base. The frame has several interfaces arranged at equal intervals on its side. On the side of the housing away from the base, several shaping units are installed at equal intervals. Each shaping unit includes a base shell fixedly connected to the outer end face of the housing. The inner side of the base shell has an interface connected to the first interface. The inner side of the base shell has a guide cavity connected to the second interface. On the side of the guide cavity away from the second interface, there is a guide opening at the end of the base shell. An extension column is slidably connected to the inner side of the guide opening. A piston block is fixedly connected to the side of the extension column near the second interface. A stop block is fixedly connected to the other end of the extension column. An infusion unit is installed on the left side of the frame body.
[0006] Preferably, the infusion unit includes a liquid tank fixed to the left side of the lower base, a bidirectional liquid pump installed on the upper side of the liquid tank, an infusion pipe fixedly connected to the left side of the bidirectional liquid pump in a communicating manner, the lower end of the infusion pipe being fixedly connected to the liquid tank in a communicating manner, a diversion pipe fixedly connected to the right side of the bidirectional liquid pump in a communicating manner, both ends of the right side of the diversion pipe being fixedly connected to the left end of the electrically controlled valve pipe, and the diversion pipe and the electrically controlled valve pipe being in a communicating manner, and a control box installed on the front side of the liquid tank.
[0007] Preferably, the lower end face of the lower housing is fixedly connected to the upper end face of the lower base, and the upper end face of the upper housing is fixedly connected to the lower end face of the top plate. A pair of rubber buffer compensation pads are provided between the upper and lower contour shaping modules, and the back sides of the upper and lower rubber buffer compensation pads are both pasted on the surface of each abutment block.
[0008] Preferably, a hydraulic gauge is installed at each of the front holes of the housing, the diameter of the piston block is the same as the inner diameter of the guide cavity, and the outer curved surface of the piston block is slidably connected to the inner curved surface of the guide cavity.
[0009] Preferably, the outer side of the guide port is provided with several notches arranged at equal angles, and the electrically controlled valve tube consists of a pipe and an electrically controlled valve installed on the pipe. The electrically controlled valve, the bidirectional liquid pump and the electric push rod of the electrically controlled valve tube are all electrically connected to the control box.
[0010] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the contour shaping module, rubber buffer compensation pad, and infusion unit are designed to allow the infusion unit to synchronously deliver hydraulic oil to each shaping unit of the upper and lower contour shaping module. This causes the piston, extension column, and abutment to extend along the mold core curve, forming a discrete support array consistent with the target curvature. The rubber buffer compensation pad then adheres to this array and automatically fills the height difference between adjacent abutments, converting the concentrated force into a continuous and uniformly distributed load. This prevents indentations or springback in the aluminum plate. During the pressure holding stage, the hydraulic system is closed, and the contour shaping module maintains the predetermined curved surface. After the mold core is removed, the flat or defective aluminum plate can be directly subjected to high-precision correction and pressing. This invention enables the curved aluminum plate processing and correction equipment to conveniently process or correct curved aluminum plates of different curvatures at a lower cost. It solves the problem that existing curved aluminum plate processing and correction equipment suffers from inconvenient mold replacement and high costs when processing and correcting aluminum plates of different curvatures.

[0019] Please see Figure 1-7 This utility model provides a technical solution: A curved aluminum single-panel processing and correction device includes a main frame 1. The main frame 1 includes a pair of symmetrically arranged bases 11. Several guide posts 12 are fixedly connected between the corners of the facing surfaces of the upper and lower bases 11. An electric push rod 13 is fixedly connected to the upper end face of the upper base 11. The drive rod of the electric push rod 13 passes through the upper base 11 and is fixedly connected to a top plate 14. The top plate 14 is slidably connected to each guide post 12. A pair of symmetrically arranged contour shaping modules 2 are installed on the lower end face of the top plate 14 and the upper end face of the lower base 11. The contour shaping module 2 includes a housing 21. Electrically controlled valve pipes 22 are fixedly connected to the left side of the housing 21 and are arranged in a continuous manner. Several equally spaced valves are provided on the side of the housing 21 away from the bases 11. The first interface 23, the side of the housing 21 away from the base 11 is equipped with several shaping units 24 arranged at equal intervals. The shaping unit 24 includes a base shell 241 fixedly connected to the outer end face of the housing 21. The inner side of the base shell 241 is provided with an interface 242 that communicates with the first interface 23. The inner side of the base shell 241 is provided with a guide cavity 243 that communicates with the interface 242. The side of the guide cavity 243 away from the interface 242 is provided with a guide opening 244 at the end of the base shell 241. The inner side of the guide opening 244 is slidably connected with an extension column 246. The side of the extension column 246 near the interface 242 is fixedly connected with a piston block 245. The other end of the extension column 246 is fixedly connected with a stop block 25. The infusion part 4 is installed on the left side of the frame body.
[0020] The infusion unit 4 includes a liquid tank 41 fixed to the left side of the lower base 11. A bidirectional pump 42 is installed on the upper side of the liquid tank 41. An infusion tube 43 is fixedly connected to the left side of the bidirectional pump 42 and is in communication with it. The lower end of the infusion tube 43 is fixedly connected to the liquid tank 41 and is in communication with it. A diversion tube 44 is fixedly connected to the right side of the bidirectional pump 42 and is in communication with it. Both ends of the right side of the diversion tube 44 are fixedly connected to the left end of the solenoid valve tube 22, and the diversion tube 44 and the solenoid valve tube 22 are in communication with each other. Hydraulic oil can be supplied to the contour shaping module 2 through the infusion unit 4. A control box 5 is installed on the front side of the liquid tank 41. The lower end face of the lower seat 21 is fixedly connected to the upper end face of the lower base 11, and the upper end face of the upper seat 21 is fixedly connected to the lower end face of the top plate 14. A pair of rubber buffer compensation pads 3 are provided between the upper and lower contour shaping modules 2. The back sides of the upper and lower rubber buffer compensation pads 3 are attached to the surface of each abutment 25. The rubber buffer compensation pads 3 can automatically... The height difference between adjacent abutment blocks 25 is filled in to convert the concentrated force into a continuous, uniformly distributed load, preventing indentations or springback in the aluminum plate. Hydraulic gauges 26 are installed at the front holes of the housing 21, allowing for the monitoring of hydraulic pressure within the housing 21 and each guide cavity 243. The diameter of the piston block 245 is the same as the inner diameter of the guide cavity 243, and the outer curved surface of the piston block 245 slides against the inner curved surface of the guide cavity 243. This design prevents hydraulic oil from flowing out of the piston block 245 and into the guide cavity 243. Leakage in the direction of port 244; several notches are provided on the outer side of the guide port 244 at equal angles. This arrangement ensures that the displacement of the piston block 245 is not affected by the air pressure in the guide cavity 243. The electric control valve pipe 22 consists of a pipe and an electric control valve installed on the pipe. The electric control valve, the bidirectional liquid pump 42, and the electric push rod 13 of the electric control valve pipe 22 are all electrically connected to the control box 5. This arrangement allows the control box 5 to control the operation of the electric control valve pipe 22, the bidirectional liquid pump 42, and the electric push rod 13.
[0021] Workflow: The operation of the curved aluminum panel processing and correction equipment is as follows. Note 1: All electrical appliances used in this application are externally powered and centrally controlled through control box 5. When it is necessary to process and correct flat aluminum materials or irregularly shaped aluminum plates with defects such as springback, twisting, and edge wavy lines into curved aluminum panels with the target curvature, a mold core completely corresponding to the target curvature can be prepared in advance. This mold core can be manufactured within hours using mature 3D printing technology, combining the advantages of low cost, fast delivery, and high strength, fully meeting the requirements. The equipment in this application has requirements for the precision and durability of the mold core; subsequently, the prepared mold core is placed between the upper and lower rubber buffer compensation pads 3. The operator first commands the electric push rod 13 to extend through the control box 5, driving the top plate 14 and the upper contour shaping module 2 to move down as a whole, so that the upper rubber buffer compensation pad 3 is close to the mold core; then, the control box 5 sends a signal to open the electric control valve pipe 22 and starts the bidirectional liquid pump 42 to put it in the right-side liquid delivery mode. In this mode, the bidirectional liquid pump 42 draws hydraulic oil from the liquid tank 41 through the delivery pipe 43, and then through the distribution... The flow pipe 44 and the electrically controlled valve pipe 22 simultaneously deliver hydraulic oil to the housing 21 of the upper and lower contour shaping modules 2. Through the diversion effect of several interfaces 23, the housing 21 further distributes the hydraulic oil to the guide cavities 243 of each shaping unit 24. As the volume of hydraulic oil in the guide cavities 243 continues to increase, the piston block 245, the extension column 246, and the abutment block 25 are simultaneously pushed towards the mold core, thereby pushing the rubber buffer compensation pad 3 to adhere to the surface of the mold core until the upper and lower rubber buffer compensation pads 3 are in complete and tight contact with the corresponding curved surfaces of the mold core. At this time, the staff can judge whether each abutment block 25 has fully pressed the mold core by monitoring the hydraulic pressure value in the housing 21. After confirming that it is in place, the control box 5 immediately closes the electric control valve pipe 22 and stops the bidirectional hydraulic pump 42. Since the hydraulic pressure in the guide cavity 243 and housing 21 is closed, the extension length of each shaping unit 24 can be kept constant, so that the upper and lower abutment blocks 25 form a height distribution array that perfectly matches the curvature of the mold core. Then, control the electric push rod 13 to retract, drive the upper contour shaping module 2 to move upward, and the mold core can be taken out.During formal processing or correction, simply place the flat aluminum material or irregularly shaped aluminum plate with defects such as springback, twisting, or edge wavy between the upper and lower rubber buffer compensation pads 3, and then drive the upper contour shaping module 2 downward again. Under the coordinated pressure of the upper and lower contour shaping modules 2, the aluminum plate can be processed and corrected into a curved aluminum single plate with the required curvature in one go. Throughout the pressing process, the rubber buffer compensation pads 3 can not only compensate for the height difference between adjacent abutment blocks 25, but also convert concentrated loads into uniformly distributed loads transferred to the aluminum plate, significantly reducing the pressure per unit area and effectively avoiding "point pressure". The resulting orange peel, indentations, or coating peeling issues can be addressed when processing or correcting curved aluminum panels with different curvatures. Simply open the electronically controlled valve 22, and the hydraulic oil will be pumped back into the liquid tank 41 via the bidirectional hydraulic pump 42. Repeating this process allows for the processing or correction of curved aluminum panels with varying curvature requirements. This enables the curved aluminum panel processing and correction equipment to conveniently process or correct curved aluminum panels of different curvatures at a lower cost, solving the problems of inconvenient mold replacement and high costs associated with existing curved aluminum panel processing and correction equipment when dealing with aluminum panels of different curvatures.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
