Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy door and window plates, and specifically relates to a plate bending device. Background Art

[0002] Aluminum alloy doors and windows are a common door and window structure. The doors and windows made of aluminum alloy materials are made by extruding aluminum alloy profiles, which are the most common types of doors and windows in daily life, with light weight and high durability. In recent years, the types of doors, windows and derivative products have been increasing continuously.

[0003] During the pressing process of processing aluminum alloy plates into doors and windows, the plates usually need to be bent. The bending operation is inseparable from a bending machine. Usually, the feeding operation is manual, and problems such as material warping may occur during this process, which is likely to cause harm to the operator. At the same time, the manual feeding method is inefficient and inaccurate. Content of the Utility Model

[0004] In view of the problems existing in the prior art, the utility model discloses a plate bending device. The technical scheme adopted is as follows: it includes a workbench, a right-side position adjusting part, a hydraulic push rod, a bending impact block, an installation groove, a guide shaft, a bidirectional lead screw, a middle part motor, a clamping installation plate, a fitting rack, an inner wall moving part, an L-shaped installation plate, an upper adjustable installation structure, an upper installation frame and a pressing wheel. The right-side position adjusting part is arranged on the right side of the workbench and the hydraulic push rod is installed through it. The output end of the hydraulic push rod is fixed with the bending impact block. When the hydraulic push rod starts, it drives the bending impact block to extrude the plate, causing it to deform and thus bend. Four installation grooves are evenly opened on the workbench. Three of the installation grooves are fixed with guide shafts, and a bidirectional lead screw is rotatably installed in one installation groove. The bidirectional lead screw is driven by the middle part motor. The fitting rack has four downward protruding parts, and the protruding parts are movably sleeved on the guide shafts and are installed in cooperation with the bidirectional lead screw. The clamping installation plate is integrally formed on the fitting rack. The inner wall moving part is arranged inside the clamping installation plate, and the upper part is integrally formed with the upper adjustable installation structure. The upper installation frame is installed through the upper adjustable installation structure. The pressing wheel is rotatably installed in the upper installation frame. By starting the middle part motor to drive the bidirectional lead screw to rotate, the clamping installation plates symmetrically arranged on the front and back sides can be made to approach each other to clamp the plate placed on the workbench. At the same time, due to the setting of the inner wall moving part, while clamping it on the front and back sides, the plate can also be moved, and its moving process is realized by starting the inner wall moving part. At the same time, in order to avoid the situation of material warping during the processing, the adjustable installation structure is operated according to the material thickness, so that the pressing wheel presses against the upper surface of the material to maintain the stability of its processing process.

[0005] As a preferred technical solution of the present utility model, the right position adjusting part includes a right slot, a right rotating lead screw, a right knob, a right T-shaped block and a vertical mounting plate. A right slot is opened in the front-back direction on the right side of the workbench 1, and the right rotating lead screw is rotatably installed therein. The right rotating lead screw is driven by the right knob. The vertical part of the right T-shaped block is placed in the right slot in a matching manner and is installed in cooperation with the right rotating lead screw. A vertical mounting plate is fixed on its horizontal part. The hydraulic push rod is installed on the rear side of the vertical mounting plate. This hydraulic push rod is a prior art and is externally powered or powered by a storage battery.

[0006] As a preferred technical solution of the present utility model, a plurality of notches are opened on the workbench, and support rollers made of hard rubber material are rotatably installed in the notches. By supporting the plate through the support rollers, the friction during the movement can be reduced, which is convenient for the inner wall moving unit to transfer the plate.

[0007] As a preferred technical solution of the present utility model, the inner wall moving part includes an inner wall slot, an inner wall roller, a roller side wall slot, a friction shaft and an upper motor. An inner wall slot is opened inside the clamping mounting plate, and the inner wall roller is rotatably installed in the inner wall slot. The inner wall roller is driven by the upper motor. A roller side wall slot is opened on the side wall of the inner wall roller, and the friction shaft is fixedly installed therein. The upper motor is powered by a storage battery. When it is started, it drives the inner wall roller to rotate, and the friction between it and the side wall of the plate is increased through the friction shaft. When the inner wall roller rotates, the plate can be smoothly moved, and the bending treatment of different positions of the plate can be realized.

[0008] As a preferred technical solution of the present utility model, the upper adjustable mounting structure includes a movable shaft, a horizontal plate, a rotating stud and a stud knob. A through hole is opened in the horizontal part of the L-shaped mounting plate, and the movable shaft passes through the through hole. Its lower end is fixedly connected to the upper mounting frame above, and the top end is fixed with a horizontal plate. The horizontal plate is installed in cooperation with the rotating stud rotatably installed on the horizontal part of the L-shaped mounting plate. The top end of the rotating stud is fixed with a stud knob. By manually rotating the stud knob, the horizontal plate can be moved downward under the screw thread fit to drive the upper mounting frame connected below to move downward, so that the pressing wheel in the upper mounting frame presses the upper surface of the plate to prevent the material from warping during the processing.

[0009] The beneficial effects of the present utility model are as follows: The front and rear clamping mounting plates are synchronously approximated through the bidirectional lead screw, the middle motor and the guide shaft, driving the inner wall moving part inside them to adaptively clamp the plate. And under the action of the inner wall moving part, the position of the plate can be moved without manual operation. The position of the hydraulic push rod is adjusted according to the different positions of the plate through the right position adjusting part, and the bending of the plate is realized by its start. The height of the pressing wheel can be adjusted through the upper adjustable mounting structure to press the upper surface of the plate to prevent it from warping during the processing.
