Description

Technical Field

[0001] The utility model relates to the technical field of roll bending machines, in particular to an automatic roll bending machine. Background Art

[0002] The roll bending of helium cylinders is a key process in their production. In the field of metal processing and manufacturing, roll bending technology is widely used to process flat materials (such as metal sheets) into circular or semi-circular shapes. The roll bending of helium cylinders usually uses metal materials with certain plasticity and bendability, such as high-strength steel.

[0003] Existing roll bending devices mostly use a three-axis type for roll bending. It is very difficult for the roundness of the processed parts rolled out to meet the use standards, which greatly affects the processing speed and efficiency. When taking out the rolled processed parts, traditional manual blanking methods are usually used. This kind of blanking method is not accurate enough, easy to waste materials and time, and existing roll bending machines need to be adjusted in multiple steps when roll bending materials with different thicknesses, thus affecting the roll bending efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatic roll bending machine to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An automatic roll bending machine includes a pressure roller adjusting mechanism, and a roll bending mechanism is fixedly arranged inside the pressure roller adjusting mechanism;

[0007] The pressure roller adjusting mechanism includes a protective box body. A support arm is fixedly connected to the outer wall of the protective box body. The top end of the support arm is fixedly connected with a cylinder I. The end of the cylinder I is fixedly connected with a moving seat. One end of a linkage rod is rotatably connected to each of the four side walls of the moving seat. The other ends of the four linkage rods are all rotatably connected to a U-shaped frame. The U-shaped frame is slidably connected to the protective box body. An extrusion roller is rotatably connected between the U-shaped frames.

[0008] Furthermore, a pushing ring is arranged inside the protective box body. Two fixing blocks are symmetrically and fixedly connected to the outer wall of the pushing ring. A connecting rod is fixedly connected to the side wall of the fixing block. The end of the connecting rod is fixedly connected with a cylinder II.

[0009] Furthermore, a side plate is highly connected to the side wall of the protective box body. A discharge port is formed in the side plate. A sliding baffle is slidably connected to the discharge port. An electric telescopic rod fixedly connected to the protective box body is fixedly connected to the side wall of the sliding baffle.

[0010] Furthermore, the rolling mechanism includes a rolling roller, a rotating shaft rotatably connected to the protective box body is fixedly connected at the center position of the rolling roller, a sprocket 2 is fixedly sleeved on the end of the rotating shaft, a servo motor is fixedly connected to the side wall of the protective box body, a sprocket 1 is fixedly sleeved on the output end of the servo motor, and a chain is meshingly sleeved between the sprocket 1 and the sprocket 2.

[0011] Furthermore, a receiving plate is fixedly connected to the side wall of the protective box body, a screw is rotatably connected to the end of the receiving plate, an internal thread block is screwed and sleeved on the screw, a pushing column is fixedly connected to the side wall of the internal thread block, a bevel gear group is fixedly connected to the end of the screw, and the bevel gear group is fixedly connected to the output end of the servo motor.

[0012] Furthermore, the top and bottom of the pushing column are fixedly connected to the limiting block, and the top and bottom of the receiving plate are fixedly connected to the limiting sleeve rod which is slidably sleeved with the limiting block.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The servo motor can drive the pushing column to move, so that the metal sheet can be continuously pushed toward the direction of the rolling roller. At the same time, the chain can drive the sprocket 2 and the rotating shaft to rotate, so that the rolling roller can roll the metal sheet. Four squeezing rollers are arranged on the outside of the rolling roller to extrude and limit the metal sheet during the rolling process, so as to ensure that the metal sheet can be rolled into a circle. When the thickness of the processed material changes, the end of the cylinder 1 can drive the moving seat to move, so that the moving seat can drive the four linkage rods to rotate, and the end of the linkage rod can drive the molding frame and the squeezing roller to slide in the protective box, so that the four squeezing rollers are away from or close to the rolling roller. Therefore, the rolling device can be quickly adjusted according to the thickness of the processed material, thereby improving the rolling efficiency.

[0015] 2. When the curling mechanism completes the curling operation of the metal sheet, the electric telescopic rod can drive the sliding baffle to move away from the discharge port, thereby opening the discharge port, and then the connecting rod and the push ring at its end are driven to move through the second cylinder, so that the push ring can push the processed cylinder out of the discharge port, thereby completing the rapid unloading operation, improving the discharge speed, and facilitating the curling of the next workpiece.
