technical field

The utility model relates to the field of steel plate forming equipment, in particular to a cold bending forming machine.

Background technique

In the production process of section steel, the coil placed on the discharge rack is generally formed into a section of a specific section through the multi-channel forming rollers in the cold bending forming machine, and then cut into an appropriate length by a cutting machine for use in production .

In the design of the cold roll forming machine, a feed guide mechanism is generally provided at the feed inlet of the main machine.

Through the above-mentioned technical solution, the shaped steel passes through the guide mechanism and enters the main machine for molding. However, there will be coil steel with different widths in the actual process, so it is necessary to limit the moving direction of the coil steel to avoid the inconsistency of the direction of the coil steel when passing the main machine. Scrap, then the set limit stopper can slide toward the center of the guide shaft during use to interfere with one side of the coil steel, while the other side of the coil steel conflicts with the limit stopper near the side of the mounting seat, The limit stop near the side of the mounting seat is in conflict with the mounting seat. Compared with the structure in which the coil steel passes through the middle, the coil steel passes through one side, which can make the guiding mechanism of the coil steel more accurate. Both the side of the seat and the limit slider can play a guiding role. If the guide is accurate, the quality of the produced steel is good, and the limit stops are installed on different screw rods respectively, so the processing of the screw rod is more accurate.

When moving to the end of the transmission element, the second connecting rod interferes with the first connecting rod.

Through the above technical solution, the set first connecting rod can enable the steel coil to slide along the first connecting rod when passing the guide mechanism, and play the role of support, and when the limit stopper slides to the end of the screw rod When the second connecting rod is in conflict with the first connecting rod, when the width of the coil is narrow, the moving distance of the limit stopper will be relatively large, and the conflict between the second connecting rod and the first connecting rod can make the transmission The fixing of the limit stop at the end of the rod is more stable.

The utility model is further configured as follows: the mounting seat is provided with a mounting groove, and the end of the guide shaft and the screw rod passing through the mounting groove is connected with a mounting plate.

Through the above technical solution, the installed mounting plate can fix both the guide shaft and the screw mandrel, and then when the screw mandrel needs to be replaced, only the mounting plate needs to be disassembled, and then the screw mandrel is disassembled, which is convenient for replacement.

The utility model is further configured as: a handle is provided on the side of the screw rod away from the limit block.

Through the above technical solution, the handle is set so that when the screw rod is turned, it can be held by hand to apply force, and the operation is convenient.

Through the above-mentioned technical scheme, because the coiled steel passing through the guide mechanism is unwound from the unwinding rack, there will still be a certain amount of deformation, so the cooperation between the first bending part and the rotating shaft can be adjusted to a certain extent. Avoid warping or unevenness of coiled steel during transmission.

The utility model is further configured as follows: the main machine includes several groups of pressure rollers parallel up and down, and the side of the first connecting rod and the second connecting rod close to the pressure rollers is provided with a second bending portion bent downward.

Through the above technical solution, the first connecting rod and the second connecting rod on the side close to the host are provided with a second bending part, and the first bending part and the second bending part form a shape similar to the deformation of the coiled steel, and the coiled steel The movement is more stable when passing the guide.

The utility model is further configured as follows: the mounting seat is provided with a bearing through which the rotating shaft penetrates.

Through the above-mentioned technical scheme, the setting of the bearing on the mounting seat can make the rotating shaft be driven to rotate when the steel coil passes through the guide device, so that the friction force between the rotating shaft and the steel coil can be reduced, and the impact on the steel coil can also be reduced. wear and tear.

The utility model is further configured as follows: the surfaces of the first connecting rod and the second connecting rod are provided with a wear-resistant silicon carbide layer.

Through the above technical solution, since the first connecting rod and the second connecting rod directly contact the coiled steel during use, there is a relatively large frictional force between the first connecting rod and the second connecting rod when the coiled steel slides , the existence of friction makes the first connecting rod and the second connecting rod wear relatively large, and the service life will be relatively short, and the set silicon carbide layer can enhance the wear resistance of the first connecting rod and the second connecting rod, Then the service life of the first connecting rod and the second connecting rod will be longer.

In summary, the utility model has the beneficial effects compared with the prior art as follows:

1. The set limit stopper is more convenient to adjust, and the adjustment accuracy is relatively high;

2. The first bending part and the second bending part provided on the guiding mechanism can make the guiding device form a structure consistent with the bending shape of the steel, so that the moving direction of the deformed shaped steel passing through the guiding mechanism will be more accurate.
