Description

Technical Field

[0001] The utility model relates to the technical field of hand-cranked rolling and bending devices, in particular to a hand-cranked rolling and bending device for realizing the bending of a lining belt. Background Art

[0002] The hand-operated bending device for realizing the bending of the lining strip is a tool for bending metal strips. It is mainly used for processing various metal strips. The device drives the gear set to work by manually rotating the handle, thereby driving the metal strip to bend. It is suitable for small-batch production, especially for small-scale bending production of stainless steel.

[0003] At present, some hand-cranked bending devices on the market have fixed pressure rollers. When metal plates of different thicknesses need to be bent, the distance between the pressure roller and the lower roller cannot be adjusted. It is necessary to replace pressure rollers of different sizes to adapt to metal plates of different thicknesses. This method is time-consuming, labor-intensive and inconvenient to operate. Therefore, a hand-cranked bending device for realizing lining belt bending is proposed. Summary of the invention

[0004] The utility model aims to provide a hand-operated rolling and bending device for realizing the bending of a lining belt, so as to solve the problems raised in the above-mentioned background technology.

[0006] As a further preferred embodiment of the technical solution: a rotating wheel is welded to the outer side wall of the driving shaft, and a connecting rod is fixedly connected to the upper surface of the rotating wheel.

[0007] As a further preferred embodiment of the technical solution: an operating rod is fixedly connected to the rear surface of the connecting rod, and a crank is provided on the outer side wall of the operating rod.

[0008] As a further preferred embodiment of the present technical solution: two sliding rods are fixedly connected to the inner side wall of the installation groove, and the outer side wall of the sliding rod is slidably connected to the nut seat.

[0009] As a further preferred embodiment of the technical solution: a metal plate is in close contact between the upper pressing roller and the lower pressing roller.

[0010] As a further preferred embodiment of the present technical solution: a leg is fixedly connected to the lower surface of the base plate.

[0012] As a further preferred embodiment of the present technical solution: an adjusting block is fixedly connected to the upper surface of the threaded rod.

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

[0014] The utility model rotates the threaded rod to make the nut seat move in the upward and downward directions inside the installation groove, and the nut seat drives the upper pressing shaft to move, and the upper pressing shaft drives the upper pressing roller to move, so that the upper pressing roller is close to the lower pressing roller. When the distance between the upper pressing roller and the lower pressing roller can match the thickness of the plate, the driving shaft is rotated to drive the driving gear to rotate, and the driven gear meshing with the driving gear drives the driven shaft and the lower pressing roller to rotate. By rotating the driving shaft back and forth, the plate is bent and formed between the upper pressing roller and the lower pressing roller. When it is necessary to roll and bend metal plates of different thicknesses, the distance between the upper pressing roller and the lower pressing roller can be adjusted, which can adapt to metal plates of different thicknesses, saves time and labor, and is relatively convenient to operate.
