Technical Field

[0001] The utility model belongs to the technical field of pressure vessel production equipment, and specifically relates to a plate rolling machine. Background Art

[0002] During the production process of pressure vessels, metal plates need to be rolled into a cylindrical shape. In the prior art, the rolling operation is generally performed by a plate rolling machine. Due to the different models of pressure vessels, the thickness of the metal plates used is different. In order to ensure the rolling effect, it is necessary to adjust the distance between the support roller and the pressure roller. Patent No. CN 214976883U discloses a plate rolling machine, including a support frame, a driving mechanism arranged at the lower part of the support frame, and a plate rolling mechanism arranged at the upper part of the support frame. The plate rolling mechanism includes working roller 1, working roller 2 and working roller 3. The output end of the driving mechanism is connected to working roller 1 and working roller 2 respectively. The working roller 3 is arranged below the connection between working roller 1 and working roller 2 and has a gap with working roller 1 and working roller 2. It also includes an adjustment mechanism for adjusting working roller 3 to approach or move away from working roller 1 and working roller 2. The adjustment mechanism is arranged on the outside of one end of working roller 3. In this patent, the position of working roller 3 is changed by a connecting piece, and the matching gap between working roller 3 and working roller 1 and working roller 2 is adjusted accordingly according to different plates. The patented adjustment mechanism has a complex structure and needs to be operated by foot. In addition, there is no auxiliary unloading mechanism. For cylinders with large volume and weight, unloading is inconvenient, time-consuming and labor-intensive. Therefore, a plate rolling machine is needed to solve the above technical problems. Utility Model Content

The flip plate is hingedly connected with a retractable push rod on a side away from the first vertical plate. The lower end of the push rod is hingedly connected to the base. The push rod is an electric push rod or a hydraulic cylinder or a pneumatic cylinder.

[0006] The vertical plate 2 is provided with a support rod, the support rod is parallel to the roller, the lower surface of the support rod is provided with a slide groove, the slide groove is provided with a screw rod 3, the screw rod 3 is connected to the forward and reverse motor 2, the screw rod 3 is threaded with a slider 3, the upper end of the slider 3 is slidably set in the slide groove, the lower end of the slider 3 is fixedly connected to a connecting rod, the lower end of the connecting rod is fixedly connected to a horizontal rod 1, and the two ends of the horizontal rod 1 are fixedly connected to the horizontal rod 2. This is arranged to facilitate the unloading of the rolled cylinder. Specifically, during the rolling operation, the horizontal rod 2 is close to the pressure roller and does not affect the rolling operation. After rolling, the horizontal rod 2 is located in the rolled cylinder. When the cylinder needs to be removed, the forward and reverse motor 2 rotates to drive the screw rod 3 to rotate, and the slider 3 drives the connecting rod and the horizontal rod 2 to move in the direction of the flip plate, so that the cylinder is pushed down the pressure plate.

[0007] The rolling operation is performed by the supporting rollers and the pressure rollers that cooperate with each other. This is the existing technology, and its principle is not repeated here.

The adjustment process is stable and efficient, and will not affect the support rods and other mechanisms, avoiding adverse effects on subsequent rolling operations and unloading.

This arrangement allows the flip plate to be parallel to the vertical plate two during the rolling operation, the limit rod to be extended, and the telescopic end of the limit rod to extend into the limit groove, which plays a role of stabilizing support for the pressure roller, making the pressure roller more stable, further improving the reliability of the rolling operation, and improving the quality of the rolling.

[0011] Preferably, one end of the support rod is fixedly connected to the vertical plate 1 through a vertical telescopic rod. The vertical telescopic rod is an electric push rod or a hydraulic cylinder. The height of the support rod can be reasonably adjusted according to needs, which is conducive to the unloading operation of the cylinder. Specifically, when the cylinder is unloaded, the vertical telescopic rod is extended, the horizontal rod 2 rises, and the cylinder is lifted up without contacting the pressure roller to reduce friction.
