Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, and in particular to an automatic four-corner forming machine. Background Technology

[0002] In the fields of packaging and electronics, the corner forming of product linings or packaging boxes is a key process to ensure the structural stability and appearance quality of products. Its forming accuracy, efficiency and surface integrity directly affect the overall quality of products. Therefore, the demand for corner forming equipment is becoming increasingly urgent.

[0003] In existing technologies, corner forming mostly relies on manual bending or semi-automatic equipment. Manual operation is not only labor-intensive and inefficient, but also makes it difficult to ensure the consistency and precision of corner forming, easily resulting in problems such as angle deviation and uneven edges. Semi-automatic equipment is often complex in structure and has poor versatility, only adapting to workpieces of specific specifications. Furthermore, due to the lack of precise guidance and buffer design, scratches are easily generated on the workpiece surface during the forming process. At the same time, the start-stop control of the equipment is cumbersome and the operation safety is insufficient, failing to meet the needs of efficient and high-quality production. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic four-corner forming machine, which has the effects of high-efficiency forming, stable quality and convenient operation.

[0005] The above-mentioned utility model objective is achieved through the following technical solution:

[0006] An automatic four-corner forming machine includes a base and a first bracket fixed on the base.

[0007] A first cylinder is vertically installed at the center of the crossbeam of the first support; the output end of the first cylinder is connected to a first mold, and four second cylinders are arranged above the first mold, with the output ends of the second cylinders connected to the second molds.

[0008] A positioning platform is installed at the center of the base, and a set of execution components is set at each of the four corners of the positioning platform;

[0009] The first cylinder, the second cylinder, and the cylinder in the actuation assembly are all connected to solenoid valves, and the solenoid valves are all electrically connected to a PLC controller.

[0010] The above technical solution enables the overall automated integrated control of the four-corner automatic forming machine. By using a PLC controller to coordinate the actions of each cylinder, the forming process can be completed without manual operation, thereby improving the automation level and forming efficiency of the equipment.

[0011] As a further technical solution of this utility model: each set of the execution components includes a third cylinder, a fourth cylinder, a fifth cylinder, a sixth cylinder, and a seventh cylinder;

[0012] The third cylinder and the fourth cylinder are inclinedly arranged on both sides of the positioning table corner to shape the inclined side of the molded part.

[0013] The fifth cylinder is located on the opposite side of the corner of the positioning table and close to the edge of the positioning table, and is used to shape the opposite side of the molded part.

[0014] The sixth and seventh cylinders are positioned directly opposite the positioning platform corner and outside the fifth cylinder.

[0015] The above technical solution enables multi-directional collaborative shaping of the four corners of the molded part. Cylinders at different positions are used to handle the oblique edge, the opposite side, and the outer auxiliary shaping respectively, ensuring the integrity and structural consistency of the four corners.

[0016] As a further technical solution of this utility model: the sixth cylinder is vertically mounted on the second bracket, and the second bracket is fixed to the base and located outside the positioning platform;

[0017] The output end of the sixth cylinder is fixedly connected to a lifting mounting base, and the lifting mounting base is fixedly connected to the seventh cylinder;

[0018] The seventh cylinder is arranged horizontally, and its output end is connected to a pressing mold.

[0019] The above technical solution enables the height of the seventh cylinder and the pressing mold to be adjustable and the horizontal pressure to be applied precisely. The sixth cylinder drives the lifting mounting seat to adjust the height, which, together with the horizontal movement of the seventh cylinder, can adapt to the forming requirements of workpieces of different thicknesses or specifications and improve the versatility of the equipment.

[0020] As a further technical solution of this utility model: the working surface of the pressing mold is adapted to the shape of the workpiece to be processed on the opposite side of the corner of the positioning table.

[0021] The above technical solution achieves a tight fit between the pressing mold and the workpiece, avoiding uneven local force or scratches on the workpiece surface caused by shape mismatch during the pressing process, and ensuring the surface quality and dimensional accuracy of the molded part.

[0022] As a further technical solution of this utility model, it also includes a start pedal, which is connected to the PLC controller.

[0023] The above technical solution enables convenient start-stop control of the equipment. Operators can trigger the PLC controller to execute the molding program by starting the pedal, which simplifies the operation process and facilitates quick interruption of operations in emergency situations, thereby improving operational safety.

[0024] In summary, this utility model has at least one of the following beneficial technical effects:

[0035] Example 1:

[0036] Reference Figure 1 and Figure 2 This utility model discloses an automatic four-corner forming machine with overall dimensions of 800cm in length, 600cm in width, and 1370cm in height. It is a small, specialized automatic four-corner forming machine used for forming. It includes a base 1 made of machined aluminum plate, on which a first support 2 is mounted. The first support 2 has a gantry-type structure, with both ends fixedly mounted on the base 1. Its crossbeam spans above the base 1, providing stable support for the upper structure of the machine.

[0037] A first cylinder 3 is vertically installed at the center of the crossbeam of the first support 2. The piston rod output end of the first cylinder 3 is connected to the first mold 4. Four second cylinders 5 are arranged above the first mold 4. The piston rod output end of the second cylinder 5 is connected to the second mold 6.

[0038] A positioning platform 7 is installed at the center of the base 1. An actuator 8 is set at each of the four corners of the positioning platform 7. Each actuator 8 includes a third cylinder 81, a fourth cylinder 82, a fifth cylinder 83, a sixth cylinder 84, and a seventh cylinder 85. The third cylinder 81 and the fourth cylinder 82 are obliquely positioned on either side of the corner of the positioning platform 7 to shape the oblique edge of the molded part. The fifth cylinder 83 is positioned directly opposite the corner of the positioning platform 7 and near its edge to shape the opposite side of the molded part. The sixth cylinder 84 and the seventh cylinder 85 are positioned directly opposite the corner of the positioning platform 7 and outside the fifth cylinder 83. Six cylinders 84 are vertically mounted on the second bracket 11, which is fixed to the base 1 and located outside the positioning table 7. The piston rod output end of the sixth cylinder 84 is fixedly connected to the lifting mounting seat 12. The lifting mounting seat 12 is guided vertically by sliding cooperation with the second bracket 11 through a linear guide pair to counteract the lateral torque of the horizontal movement of the seventh cylinder 85. The lifting mounting seat 12 is fixedly connected to the seventh cylinder 85, which is arranged horizontally. The piston rod output end of the seventh cylinder 85 is connected to the pressing mold 13. The working surface of the pressing mold 13 is adapted to the shape of the workpiece to be processed on the opposite side of the corner of the positioning table 7.

[0039] This automatic four-corner forming machine also includes a start pedal 14, which is connected to a PLC controller 10.

[0040] Reference Figure 3 The 220V AC power supply is connected to a 24V switching power supply to provide 24V DC power to the PLC controller 10, the start pedal 14 circuit, and the solenoid valve 9. The signal terminal of the start pedal 14 is connected to the digital input port of the PLC controller 10 to trigger the forming program. The digital output ports of the PLC controller 10 are connected to the coil terminals of the solenoid valves 9, where solenoid valve 9a controls the first cylinder 3, solenoid valve 9b controls the second cylinder 5, and solenoid valves 9c, 9d, 9e, 9f, and 9g control the third cylinder 81, fourth cylinder 82, fifth cylinder 83, sixth cylinder 84, and seventh cylinder 85 in the execution assembly 8, respectively. Through electrical connection, the PLC controller 10 can output switching signals according to a preset timing sequence to drive the solenoid valves 9 to switch, thereby controlling the extension and retraction of the corresponding cylinders, realizing automated and high-precision control of the four corner forming of the workpiece.

[0041] The working process of this utility model is as follows:

[0042] Turn on the equipment power supply (AC 220V) and connect the compressed air source (0.6-0.8MPa) to ensure that the power supply and air source for solenoid valve 9, PLC controller 10 and each cylinder are stable.

[0043] Positioning stage: The workpiece to be processed is placed on the positioning table 7 to achieve the initial positioning of the workpiece and ensure that the four corners of the workpiece correspond to the working positions of the execution component 8.

[0044] First pressing: The operator presses the start pedal 14, which sends a trigger signal to the PLC controller 10. The PLC controller 10 controls the first cylinder 3 to move through the solenoid valve 9. The piston rod of the first cylinder 3 drives the first mold 4 to move downward, pressing the workpiece body onto the positioning table 7, thus achieving overall fixation and initial bending of the workpiece.

[0045] Four-corner fine adjustment: While the first mold 4 is pressing, the PLC controller 10 synchronously controls the four second cylinders 5 to move. The piston rod of the second cylinder 5 pushes the second mold 6 to move towards the four corners of the workpiece. Through precise pressure compensation, the force on the four corners is evenly distributed, avoiding forming deviations caused by insufficient local pressure.

[0046] Bevel forming: PLC controller 10 triggers the third cylinder 81 and the fourth cylinder 82 according to the preset timing. The piston rods of the two cylinders extend synchronously. Since the third cylinder 81 and the fourth cylinder 82 are inclined on both sides of the corner of the positioning table 7, their thrust acts on the workpiece in an oblique direction, bending the beveled edges of the four corners to the preset angle.

[0047] Side compaction: After the bevel is formed, the piston rod of the fifth cylinder 83 is lifted vertically upward. Because the fifth cylinder 83 is close to the edge of the positioning table 7 and faces the corner of the positioning table 7, its thrust is directly applied to the opposite side of the workpiece, compacting the side and maintaining a right angle shape.

[0048] Composite pressing: PLC controller 10 controls the operation of the sixth cylinder 84. The piston rod of the sixth cylinder 84 drives the lifting mounting seat 12 to move vertically along the linear guide pair, adjusting the height of the seventh cylinder 85 to match the thickness of the workpiece. Then, the piston rod of the seventh cylinder 85 advances horizontally, driving the pressing mold 13 to move outward of the workpiece. Since the working surface of the pressing mold 13 matches the shape of the workpiece, it can closely fit the outer side of the workpiece and apply pressure to complete the pressing of the outer part.

[0049] Shape retention and shaping: PLC controller 10 maintains the pressing state of each cylinder for 3 seconds to fully cure the glue at the joint of the workpiece and ensure the stability of the shape after molding.

[0050] Reset: After the molding is completed, the PLC controller 10 controls the piston rods of all cylinders to retract through the solenoid valve 9. The cylinders of the first mold 4, the second mold 6, the pressing mold 13 and each execution component 8 return to their initial positions, waiting for the next processing cycle.

[0051] The implementation principle of this utility model is as follows: The PLC controller 10 coordinates the action sequence of each cylinder to achieve automated, high-precision four-corner forming; after receiving the trigger signal from the start pedal 14, the PLC controller 10 controls the extension and retraction of the first cylinder 3, the second cylinder 5, and each cylinder in the execution assembly 8 via the solenoid valve 9. The first cylinder 3 drives the first mold 4 to achieve initial workpiece positioning and bending; the four second cylinders 5 are assisted by the second mold 6 to adjust the edge posture; the positioning table 7 ensures the initial position accuracy of the workpiece; in the execution assembly 8, the third cylinder 81 and the fourth cylinder 82 utilize the inclined arrangement characteristics to... The workpiece is shaped by applying pressure to the four corners of the workpiece from both sides. The fifth cylinder 83 is close to the edge of the positioning table 7 and bends the opposite side to ensure right angle accuracy. The sixth cylinder 84 drives the seventh cylinder 85 to adjust its height through the lifting mounting seat 12 to adapt to workpieces of different thicknesses. The seventh cylinder 85 drives the matching pressing mold 13 to apply horizontal pressure to ensure the fit of the outer part and avoid scratches. Each cylinder works in coordination through a preset program of the PLC controller 10, reducing manual intervention and solving the problems of low efficiency, unstable quality and complicated operation of the existing technology. It achieves the effect of simple structure, good forming effect, fast speed and stable operation.

[0052] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
