Description

  The present invention relates to a kind of transport plate roll forming machine, which has a structure in which the plate material is flattened by two sets of rolls whose horizontal distance gradually decreases (or gradually increases), and moves up and down with respect to the gap between the upper and lower rolls of the roll forming machine. It is related with the structure which adjusts.

  When applying a metal plate material to press working, in order to keep the plate material at a certain flat level, roll forming is performed and flattened by an overlap prevention facility. The known transport plate material roll forming machine is one of the equipment that roll-forms a plate material to prepare it flat, and the conventional state of the art will be described with a commonly used roll forming machine.

  Please refer to FIGS. In the conventional transport plate material roll forming machine 1, a set of upper rolls 11 and a set of lower rolls 12 are provided, and the metal plate material is introduced into the roll forming machine structure from the plate material inlet 13 and is flattened. Further, it is sent to the plate material outlet 14. During the roll forming operation, the stress received by the plate material inlet 13 is different from the stress received by the plate material outlet 14, because the plate material fed from the plate material inlet 13 is the most uneven. For example, there is a difference in the stress between the outermost side and the innermost side of the plate material wound in a roll shape, and therefore the stress received by the upper and lower rolls 11, 12 approaching the plate material inlet 13 is the upper and lower rolls near the plate material outlet 14. 11 and 12 greater than the stress experienced. The transport plate material roll forming machine 1 cannot be adjusted with the deformation of the plate material due to the above-described stress change.

  The distance between the outer periphery of each wheel body and the outer periphery of the adjacent wheel body is called the wheel distance h. As clearly shown in the figure, in the upper roll 11 or the lower roll 12 arranged horizontally, two adjacent The roll ring h is the same or close numerical value. For this reason, since the upper and lower rolls 11 and 12 from the plate material inlet 13 to the plate material outlet 14 apply the same action force to the plate material, a good flattening effect cannot be obtained.

  Next, when cleaning or replacing the upper and lower rolls of the transport plate roll forming machine, the entire roll forming mechanism must be removed, which is very inconvenient, and as shown in FIG. Such a transport plate material roll forming machine is provided.

  The transport plate material roll forming machine 2 shown in FIG. 3 has a lower seat 22 fixed to a machine base 21, and the lower seat 22 includes a set of lower rolls 23 having the same wheel distance. The elevator 24 is connected, and the elevator 24 can adjust the height of the lower seat 22 of the entire lower roll 23. An upper seat 25 corresponding to the lower seat 22 is pivoted. The upper seat 25 includes a pair of upper rolls 26, and the angle of the pair of upper rolls 26 can be adjusted by an adjusting mechanism 27. Then, the plate material to be transported is rolled and flattened.

  The lift rod 28 is axially contacted at one end different from the pivoted one end of the upper seat 25, and the lift rod 28 is controlled by the lift mechanism 29 to open the upper seat 25 to an angle, and two sets of rolls or Used for repair and cleaning of other parts. The lifting mechanism 29 can open only one side of the upper seat 25, and the roll closer to the pivot end is harder to clean and inconvenient to replace parts.

  In addition, after the upper seat 25 is closed again, the axial distance between the upper roll 26 and the lower roll 23 cannot be determined by the lifting rod 28 at one time. This axial distance refers to the distance between the axial centers of any one of the two sets of rolls and the ring body in a roll forming relationship. Therefore, the lower seat 22 or the upper seat 25 after being closed is adjusted with respect to the worm lift 24 or the adjusting mechanism 27 by a manual method, and a good axial distance between the set of the upper roll 26 and the lower roll 23 is obtained. obtain. Thereby, due to the structural design failure of the transport plate material roll forming machine 2, it is necessary to adjust the axial distance between the upper roll 26 and the lower roll 23 in use.

One side of the two sets of rolls is a plate material inlet and the other side is a plate material outlet.

  Among them, in each set of rolls, the distance between the outer circumferences of two adjacent wheel bodies is the wheel distance, and the closer to the plate material inlet, the larger the wheel distance of the two adjacent wheel bodies becomes at the plate material outlet. The closer the distance is, the smaller the distance between two adjacent rings.

  In other words, the distance between the axes of the two rings of the roll is one axis distance, and the closer to the plate entrance, the greater the axis distance between the two rings of the roll and the closer to the plate exit. The closer the roll, the smaller the axial distance between the two rings of the roll.

  When a plate material (not shown) packed irregularly or circularly is sent to the plate material inlet 35 to perform flat roll forming, the plate material is first rolled by the upper roll 33 and the lower roll 34 of the plate material inlet 35. Formed and flattened. The plate material before roll forming may have a relatively large number of bent or deformed portions. Therefore, the acting force exerted on the plate material by the upper roll 33 and the lower roll 34 adjacent to the plate material inlet 35 is also increased.

  The wheel distance h of the present embodiment is designed in such a manner that it gradually decreases from the plate material inlet 35 toward the plate material outlet 36 or gradually increases from the plate material outlet 36 toward the plate material inlet 35, and therefore the working force for successively rolling the plate material is increased. In addition, the reaction force from the plate material is reduced. When the plate material is fed toward the plate material outlet 36, the axial distance d of the upper roll 33 and the lower roll 34 that perform roll forming jointly by gradually decreasing the wheel distance h is also gradually decreased, so that the plate material is deformed by roll forming. Is made flat, the flattening effect of the plate material is improved, and the defective rate of flattening of the plate material is reduced.
