Description

Technical Field

[0001] This utility model relates to the field of processing rigid polyurethane sandwich panels with metal surfaces, and in particular to a cutting device for rigid polyurethane sandwich panels with metal surfaces that has a positioning function. Background Technology

[0002] Metal-faced rigid polyurethane sandwich panels refer to sandwich panels with two layers of thin metal sheets and a core of rigid polyurethane. Polyurethane, short for polyurethane ester, is a general term for macromolecular compounds containing repeating urethane groups on their main chain. It is formed by the addition polymerization of organic diisocyanates or polyisocyanates with dihydroxy or polyhydroxy compounds.

[0003] Metal-faced rigid polyurethane sandwich panels require cutting during processing. In existing technologies, cutting devices can only perform simple fixing of the metal-faced rigid polyurethane sandwich panels and cannot adjust their position. This results in a large number of defective products during cutting, making it difficult to meet the needs of industrial production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot adjust the position of rigid polyurethane sandwich panels with metal surfaces, and to propose a cutting device for rigid polyurethane sandwich panels with positioning function.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A metal-faced rigid polyurethane sandwich panel cutting device with positioning function includes a worktable. A pair of fixed rods are provided on the side of the worktable, and a pair of sliding rods are fixed on each of the fixed rods. Two pairs of sliding grooves are opened on the lower surface of the worktable, and the two pairs of sliding rods are slidably connected to the two pairs of sliding grooves respectively. A pair of fixed blocks are provided on each of the fixed rods, and a round rod is rotatably provided on each of the fixed blocks. A rotating frame is fixed at the lower end of each round rod, and a pair of rollers are rotatably provided on the rotating frame. A transmission assembly is provided below the worktable.

[0007] Preferably, the transmission assembly includes a first motor, which is fixedly mounted on the lower surface of the workbench. A first helical gear is fixedly mounted on the output shaft of the first motor. Connecting blocks are fixedly mounted on each of the fixed rods. A rotating rod is threaded between a pair of connecting blocks. A second helical gear is fixedly mounted on the rotating rod. The second helical gear meshes with the first helical gear.

[0008] Preferably, both ends of the rotating rod are threaded, and the threads at both ends are in opposite directions.

[0009] Preferably, each of the fixing blocks is fixedly provided with a winding spring, and the two pairs of winding springs are respectively fixedly connected to the upper ends of the two pairs of round rods.

[0010] Preferably, each of the fixed rods has a pair of sliding grooves, each of the fixed rods has a bidirectional lead screw rotatably mounted inside, each of the sliding grooves has a slider sliding inside, each pair of sliders is threadedly connected to a pair of bidirectional lead screws, each pair of sliders is fixedly connected to a pair of fixed blocks, each of the ends of the fixed rods has a second motor fixedly mounted, and each pair of second motor output shafts is fixedly connected to a pair of bidirectional lead screws.

[0011] Preferably, a cutting assembly is fixedly mounted on the worktable.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the first helical gear drives the second helical gear to rotate, the second helical gear drives the rotating rod to rotate, the rotating rod drives the fixed rod to move towards the center through the connecting block, the fixed rod drives the rotating frame to move towards the center, and the rotating frame drives the rollers to fix and clamp the four sides of the cast copper part. During the fixing and clamping process, the rotating frame drives the rollers to adjust the position of the metal-faced rigid polyurethane sandwich panel. When the metal-faced rigid polyurethane sandwich panel is not located in the center of the workbench, the four pairs of rollers can push the metal-faced rigid polyurethane sandwich panel to the center position, which greatly improves the yield rate of the metal-faced rigid polyurethane sandwich panel after cutting.

[0014] 2. In this utility model, a pair of second motors simultaneously drive the bidirectional lead screw to rotate. The bidirectional lead screw drives the fixed block to move through the slider, so that the device can be dynamically adjusted according to the size of the metal-faced rigid polyurethane sandwich panel. The adjustment method is very convenient, making the application scenarios of the device more extensive.

[0015] 3. In this utility model, the cutting assembly cuts the metal-faced rigid polyurethane sandwich panel. After the cutting is completed, the rotating frame releases its grip on the metal-faced rigid polyurethane sandwich panel, and the winding spring drives the rotating frame to rotate until the rotating frame returns to its original position, which facilitates the next clamping of the metal-faced rigid polyurethane sandwich panel. The device has a high degree of automation. Attached Figure Description
