Description

[Detailed description of the invention] The present invention relates to the improvement of roll forming equipment.The purpose of this invention is to improve roll forming equipment in which roll groups are unitized every several stages, and the center position of the roll group is can always be set at a fixed position on the base,
Furthermore, the purpose is to simplify the groove path of the roll drive source.

If a pair of upper and lower rotating rolls is installed in tandem in multiple stages to perform continuous molding, and the roll group is made into a unit every several stages, and the unit can be removed and replaced at will from the top surface of the base, those rolls When replacing the unit, the position of the roll center must be changed each time the roll width changes.

In other words, since the gear groups that individually apply rotational force to each roll unit arranged in tandem are always fixed at a fixed position on the base of the molding machine, In order to connect and engage the roll gears protruding from the side surfaces of the roll unit, it is necessary to keep one side of the roll unit close to the drive gear group.

However, in this case, since the width dimensions of the rolls are different, the center of the roll, that is, the roll center, changes every time the roll unit is replaced.

As a result, various mechanisms centered around the roll forming machine, namely,
Uncoiler-Leveler-Pre-notch-Shear and Welding Machine-Cutting Equipment One-hole hole requires moving various items such as machines, conveyor lines, etc. to match the roll center, which not only requires severe labor but also requires a lot of work. There were also problems in terms of gender, such as being extremely inefficient.

Therefore, the present inventor conducted further various studies regarding these improvements.

For example, if the center of the roll unit, that is, the roll center, is to be kept constant at all times, the drive roll group is fixed and cannot receive the driving force of the rolls.

In addition, each drive gear group is connected to one motor,
Moreover, the number of gears corresponding to the number of stages of the rolls are installed in parallel in the continuous direction of the roll stand through universal joints, so it is not easy to improve this.

However, in subsequent research, these difficulties were finally resolved.

In other words, it is not necessary to connect the drive gear and the motor at the same time for all gears; for example, if you connect the motor directly to only the first gear, the rest will be powered. It was discovered that power could be transmitted sequentially to the second and subsequent drive gears through the meshing roll gears on the side of the roll stand receiving the transmission, and in order to move a series of drive gear groups toward and away from each roll stand. We succeeded in constructing a structure that can be slid freely on the base.

In this way, even if roll stands with different roll widths are replaced, the roll center can always be held at a constant position.

The specific content of the present invention will be explained below according to an illustrated embodiment. 1 is a base; 2 is a movable bed that can move on the base in the direction of the arrow (direction that intersects the continuous direction of the roll forming stand); The movable bed 2 has a plurality of cylindrical racks 10 provided below screwed into screw bolts 11 meshing with a bevel gear 12, and is moved along the upper surface of the base 1 in the direction of the arrow by the rotational speed of the screw bolts 11. It is now possible to do so.

Reference numeral 3 indicates a fixed hinge of the bevel gear 12 described above. Starting force is applied to the bevel gear 12 by forward and reverse rotation of the motor 14, and each bevel gear 12 is connected to each other by a propeller shaft 13, so that all the bevel gears 12 are synchronized. It is configured to be able to rotate.

Further, at the top of the moving bed 2, rotating gears RG1 to RG1o protruding in the side direction of each roll stand, which will be described later, are provided.
A plurality of drive gears 61 to G1 are positioned so that they can engage each of the drive gears 61 to G1.
□ are provided, and these drive gears are installed on a pair of upright brackets (only 8a is shown).

As shown in FIG. 5, the distance between each of the driving gears 01 to G1□ is such that, for example, the distance between the driving gears G3 and G4 can be engaged with the rotating gear RG3, which will be described later, to which power is to be transmitted. Moreover, there is a rotating gear RG in the middle.
A bearing 9b is provided large enough to allow the rotational extension shaft 19 of No. 3 to enter, and drive gears G1 and G2, G2 and G3, G5 and 66 are provided.
The same structure will be used thereafter.

The driving force is applied to the drive gear G1 by the motor 4, and the rotation of the main rotary wheel 6 is directly transmitted to the drive gear box 7 via the reducer 5, whereby the driving force is applied only to the first drive gear G1. is transmitted.

30 indicates a stand on which the motor and speed reducer are mounted.

Reference numeral 15 denotes a centering rail integrally protruding along the longitudinal direction of the base 1; 23 denotes a telescoping cylinder having a hook 26 at its tip via a cylinder rod 25;
Its base end is rotatably fixed to the base 1 by a pin 22, and its upper part is connected to the tip of a rod of another cylinder 27 by a hinge 24.

28 is a fixed hinge of the cylinder 27.

RU1 to RU5 are roll units that are made up of a pair of upper and lower forming rolls R in two stages each, and each roll unit applies a pair of upper and lower pressurizers between a rear rest 18a and a front rest 18b that are set up on a pedestal 16. Roll R forward and backward 2
Each stage is rotatably supported.

Note that 21 indicates a hanging portion provided at each of the roll shaft tips RU□ to RU5, and 17 indicates a groove of a size that can fit into the centering rail 15 described above.

Reference numeral 20 denotes a gear integrally attached to the upper roll shaft, and 21 represents a gear integrally attached to the lower roll shaft. The upper gear 20 is constantly meshed with the lower gear 21 coaxial with the rotation gears RG1 to RG1o described above, and rotates the upper and lower rolls. It consists of each stage.

Furthermore, the roll shaft tip 19 of the lower roll R is adapted to match with the aforementioned bearing 9b on the moving bed 2 facing thereto.

Furthermore, the diameters of the rotating gears RG1 to RG1o are configured to fit the drive gears G1 and G2, G2 and G3, and match the intervals between the respective drive gears up to Gu, so that they all mesh with each drive gear. There is.

Therefore, when the motor 14 is rotated forward, each bevel gear 12
As the screw bolt 11 rotates through the cylindrical rack 10 screwed into the screw bolt 11, the moving bed 2 moves toward the tip of the screw bolt 11, that is, toward the roll stand, and the bearing 9b of the moving bed 2 rotates. When aligned with and fitted into the roll shaft tip 19, the drive gears 61 to Gll simultaneously complete meshing with the rotation gears RG1 to RG1o.

Then, the rotation of the motor 14 is stopped, and then the rotation of the motor 4 is stopped.
When rotated, the driving force is transmitted to the reducer 5, the main rotating wheel 6,
It is transmitted via the drive gearbox 7 only to the first drive gear G1.

The drive gear G1 rotates the rotation gear RG1 that meshes with it, and the rotation gear RG1 rotates the drive gear G2 that meshes with it adjacently, and the drive gear G2 rotates the rotation gear RG2.
The rotating gear RG2 acts to rotate the driving gear G3, and so on, all the way to the driving gear G1□ and the roll gear RG1o in a synchronous manner.

Here, roll forming work is carried out, and if it becomes necessary to replace the forming rolls afterwards, the motor 14 is reversely rotated to move the movable bed away from the forming rolls, thereby driving gears 61 to G1□ All engagements of the rotation gears RG1 to RG1o are released.

Next, the rod of the compound cylinder 27, which has been extended by the rod 25 of the cylinder 23, is extended to remove the hook 26 from the base 16 of each roll unit, thereby releasing the clamp of each roll unit to the base 1.

After that, the roll units are successively lifted and removed from the base 1, and another roll unit is successively fitted into the groove 17 provided on the base 16 to the center alignment rail 15 protruding from the top surface of the base. After arranging each roll unit (RU1 to RU5) with the hook 26 by operating the two cylinders 23 and 27 described above,
is fixed to the top of the base.

In this state, when the motor 14 is rotated in the forward direction to move the moving bed 2 by the required amount again in the direction of the roll unit, the drive gears 61 to Gll are rotated to the rotation gears RG to RG1o.
bite and complete work preparation.

As is clear from the detailed description above, according to the invention of the present application, even if roll stands with different roll widths are replaced, the roll center is always held at a constant position, so the uncoiler and other related There is no need to rearrange levelers and other equipment to match each roll center each time, and there is no need to disconnect from the drive gear when replacing the roll unit, which greatly improves work efficiency. It is advantageous.

In addition, the drive gear can be moved by simply moving the moving bed, eliminating the need for an inexpensive universal joint between the drive motors as in the past, simplifying the structure, and producing various beneficial effects. It is.
