Description

Feeding mechanism for plate bending machine and plate bending machine

Technical Field

The utility model belongs to the technical field of the sheet metal shaping, relate to a feed mechanism and veneer reeling machine for veneer reeling machine very much.

Background

The plate rolling machine is mainly used for forming a workshop metal plate, the metal plate is rolled into a circle, an arc or a cone with a certain size, and the shape and the size of the rolled plate can be adjusted by adjusting the distance between the rollers at the two sides of the plate rolling mechanism and the upper roller. Common plate bending machines mainly include three-roll plate bending machines, four-roll plate bending machines and the like.

As shown in fig. 1, the three-roll plate bending machine is provided with 1 upper roll 102 and 2 lower rolls 103, and rolls a metal plate into a cylinder 101 by using the principle of three-point bending and rolling. The three-roller plate bending machine has the advantages of simple structure, low cost and the like, and has the defects of low bending precision and no matched feeding mechanism.

As shown in fig. 2, the four-roll plate bending machine is a variant of the three-roll plate bending machine, and is provided with 1 upper roll 102, 1 lower roll 103 and 2 side rolls 104, but only three rolls participate in the bending motion of the plate at the same time in the process of forming the cylinder 101 by the actual plate bending. Compared with a three-roller plate bending machine, the four-roller plate bending machine has a complex structure and higher manufacturing cost. Of course, the four-roll plate bending machine has higher rolling precision than the three-roll plate bending machine, but is still not provided with a feeding mechanism.

Because traditional veneer reeling machine is not equipped with feed mechanism, needs artifical manual material loading, this mode is comparatively dangerous, causes staff's unexpected injury easily, and traditional veneer reeling machine feeding can not guarantee the sharp material loading of panel, causes the generating line of barrel out of plumb or the circular arc of rolling out to be not just easily.

Specifically, when the plate bending machine is used for bending a plate with a small plate size, two workers are required to manually carry out steel plate feeding during feeding of the plate bending machine, and the mode mainly has the following two defects: (1) if the steel plate falls off accidentally, accidental injuries such as bruising or gouging of workers are easily caused; (2) the manual feeding can not ensure the linear feeding of the plate, namely, the plate central line is parallel to the roller central line when the plate enters the roller of the plate bending mechanism, a third person is required to observe and command the plate by the plate bending mechanism, the plate can be fed linearly only by a plurality of tests, and the bobbin which is not rolled out by the third person is not straight. This results in reduced efficiency and wasted labor.

When the plate size of the rolled plate is large, the plate needs to be transported by a crown block, and the auxiliary personnel is still needed to ensure the linear feeding of the plate and place the plate to deviate.

In conclusion, the traditional plate bending machine usually adopts a crown block to transfer and cooperate with workers to manually feed materials, and the mode is dangerous and easily causes accidental injuries to the workers. In addition, the traditional feeding mode of the plate bending machine cannot ensure the linear feeding of the plate, and the non-perpendicularity of the generatrix of the winding drum or the non-correction of the rolled circular arc is easily caused.

Therefore, there is still a need for improvements in rolling machines to improve their performance.
