Description

Technical Field

[0001] This invention relates to the field of composite sandwich panel equipment technology, specifically to a bending processing device for composite sandwich panels and its usage method. Background Technology

[0002] Composite sandwich panel products consist of two layers of molded metal or other material panels and a high-polymer heat-insulating core that is foamed and cured directly between the panels.

[0003] For example, the invention patent disclosed in publication number CN111976015A discloses a bending processing equipment for composite sandwich panels, which includes a base plate, a counterweight foot fixedly installed on the bottom surface of the base plate, a support frame fixedly installed on the top surface of the base plate, a fixed panel fixedly installed on the top of the support frame, a limit frame throughly installed on the top and bottom surfaces of the fixed panel, and a limit groove opened on the front and rear sides of the inner wall of the limit frame.

[0004] Although the above-mentioned equipment can bend composite sandwich panels, it lacks sufficient automation in centering the bending of the panels and is also insufficient in adapting to bending panels of different widths and lengths. Therefore, a bending processing device for composite sandwich panels and its usage method are needed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a bending processing device for composite sandwich panels and a method for using the same, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bending processing device for composite sandwich panels, comprising a bending device, a sandwich panel, a guiding device, a profile support column, and a positioning device.

[0007] The guide device has four fixed support profiles at its lower end face corners, and a positioning device is fixedly installed near the front of the guide device on its upper end face. A bending device is installed near the middle of the upper end face of the guide device, and a sandwich plate is fixedly engaged between the bending device and the positioning device.

[0008] The guiding device includes a positioning groove, a support plate, a servo motor, a ball screw, and a fixed plate. The lower end face of the support plate is symmetrically provided with a fixed plate for limiting the position, and the ball screw is rotatably engaged with the inner end face of the two sets of fixed plates. The rear end face of the fixed plate is fixedly provided with a servo motor facing the ball screw. The inner end face of the support plate is provided with a positioning groove facing the ball screw.

[0009] Preferably, the bending device includes a connecting side plate, a stepper motor, a central guide groove, a first bending pressure plate, a bidirectional lead screw, a guide slide, a support bracket, a central clamping plate, a guide slide shaft, and a ball bearing slide. A central guide groove is provided at the center of the inner end face of the first bending pressure plate. A connecting side plate is symmetrically arranged on the side end face of the first bending pressure plate, and a guide slide shaft for guiding is symmetrically arranged on the front end face of the connecting side plate. A support bracket is fixedly installed on the rear end face of the two sets of connecting side plates, and a bidirectional lead screw is rotatably engaged on the inner end face of the support bracket. A stepper motor is arranged on the side end face of the support bracket directly opposite the bidirectional lead screw. A guide slide is symmetrically threaded to the inner end face of the support bracket through the bidirectional lead screw, and a central clamping plate is fixedly arranged at the center of the lower end face of the guide slide. A ball bearing slide is fixedly installed at the center of the lower end face of the first bending pressure plate.

[0010] Preferably, the positioning device includes a second bending pressure plate, a fixed guide groove, a limiting slide, a fixed guide hole, and a positioning plate. The fixed guide groove is provided at the center of the inner end face of the second bending pressure plate, and the limiting slide is symmetrically provided at the side end face of the second bending pressure plate. The limiting slide is symmetrically provided at the inner end face, and two sets of positioning plates are provided at the center of the lower end face of the second bending pressure plate.

[0011] Preferably, the centering guide groove is directly opposite the fixed guide groove, and the height of the centering guide groove and the fixed guide groove is equal to the thickness of the centering clamping plate. The centering clamping plate is slidably engaged inside the first bending pressure plate through the centering guide groove, and the centering clamping plate is slidably engaged inside the second bending pressure plate through the fixed guide groove.

[0012] Preferably, the second bending pressure plate is coaxial with the first bending pressure plate, and the guide slide shaft is slidably engaged with the limiting slide block through the fixed guide hole. The two sets of fixed guide holes can cooperate with the sliding limit of the guide slide shaft, thereby providing sufficient guiding foundation for the forward bending of the bending device.

[0013] Preferably, the ball slide is adapted to the ball screw, and the bending device is threadedly slidably connected to the upper end face of the guide device through the adaptation of the ball slide and the ball screw. The ball screw can drive the ball slide to move forward or backward stably, providing sufficient support for bending the sandwich panel between the first bending plate and the second bending plate.

[0014] Preferably, the inner walls of the two sets of central clamping plates are fitted and connected to the sandwich panel, and the ball bearing slide is slidably engaged with the positioning slide groove. The two sets of central clamping plates with centripetal or centrifugal displacement can centrally limit the side of the sandwich panel, thereby improving the stability of the sandwich panel in the bending device and positioning device, and facilitating subsequent bending operations.

[0015] A method of using a bending device for composite sandwich panels includes the following steps:

[0016] S1: Before bending, the workers can position the hoisting equipment to the side of the guide device, which can quickly hoist and position the sandwich panel to supply material for subsequent bending;

[0017] S2: To center the sandwich panel after loading, the operator can start the stepper motor, which can synchronously drive the two sets of guide slides to perform centripetal displacement through the bidirectional lead screw. The two sets of guide slides can drive the two sets of centering clamps to center the sandwich panel located in the middle.

[0018] S3: To stably bend and shape the sandwich panel, the operator can start the servo motor. The servo motor can drive the ball slide connected to it to move forward through the ball screw. The first bending plate can slowly drive the sandwich panel that is in contact with it toward the rear of the second bending plate until the front of the first bending plate is completely in contact with the second bending plate, thus completing the bending operation of the sandwich panel.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. By setting up a guiding device and a positioning device, when bending sandwich panels of different thicknesses, the servo motor can be connected to the ball screw and the ball slide through the thread, thereby driving the first bending pressure plate and the second bending pressure plate to slide and limit, so that the first bending pressure plate and the second bending pressure plate can stably bend and limit the sandwich panel, thereby improving the stability of the equipment for bending and positioning sandwich panels of different thicknesses.

[0021] 2. By setting up a bending device, the present invention enables the stepper motor to synchronously drive two sets of central clamping plates to perform centripetal displacement through a bidirectional lead screw during the bending and shaping of the sandwich panel, thereby accurately positioning and centering the sandwich panel to be bent, and improving the accuracy of subsequent bending of the sandwich panel.
