Description

Gear type automatic placing device for backing plate of flatting mill

Technical Field

The invention belongs to the technical field of metallurgical equipment, and particularly relates to an automatic placing device for a gear type flatting machine base plate.

Background

With the rapid development of national economy, wide and thick plates, especially high-strength wide and thick plates, are applied more and more widely in various industries, the demand is greater and greater, and meanwhile, the requirements on the plate shape flatness of the used wide and thick plates in various fields are also stricter. However, the steel plate can be bent and deformed during cooling and transportation in the production process, so that the product can not meet the use requirement. Moreover, as the thickness of the steel plate increases, the steel plate can be bent and deformed during cooling and transportation. Therefore, the steel sheet needs to be straightened or flattened before it is shipped. The straightening process of the steel plate is a process of multiple reverse bending, and the straightening force required for straightening the steel plate is very large. The thickness of the hot-rolled steel plate is limited to be less than 100mm under the limitation of the straightening capability of the straightener, the thickness of the cold-rolled steel plate is not more than 40mm, and the steel plate with high strength can be straightened by the straightening equipment. The steel plate with large thickness and high strength which cannot be straightened by the straightening equipment is usually flattened by a steel plate flattening machine, so that the flatness of the plate type of the steel plate reaches the use requirement.

Generally, the steel plate is flattened by placing a backing plate at different positions above or below the steel plate according to different bending degrees and bending shapes of the flattened steel plate. When the steel sheet bending position is more, need carry out a lot of to the steel sheet and flatten many times, so need place the backing plate many times. However, when the traditional flatting mill equipment flattens the steel plate, the unevenness of the steel plate is measured by experience, the base plate is manually placed below or above the steel plate after the base plate placing position is judged by experience, and the pressure is provided by the pressure head to realize the counter bending. In addition, when the steel plate is flattened for the next time after the flattening process is finished for one time, the base plate and the steel plate are adhered, so that the labor intensity for taking and placing the base plate is increased.

In conclusion, the prior flattening equipment has the defects of large human factors, high labor intensity, low automation degree, low production efficiency, large potential safety hazard and the like when flattening a steel plate.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings:

as shown in figure 9, the gear type automatic placing device for the backing plate of the flatting machine is respectively arranged on the left side and the right side of a workbench IV of the flatting machine, the structure of the device is completely the same, a swinging device 4 of the device can be placed between a front upright post and a rear upright post I and II of the flatting machine and I ' and II ', and the swinging device 4, an electromagnet 5 and the backing plate III are positioned in a space between the front upright post and the rear upright post I and II ' of the flatting machine after being retracted.

The electromagnet 5 has certain magnetism in the power-on state and no magnetism in the power-off state.

When the transverse moving is needed, the transverse moving speed reducing motor 2.4 rotates to drive the gear shaft 2.6 to rotate, and under the meshing action of the gear shaft 2.6 and the transverse moving rack 1.3, the gear shaft mounting seat 2.5 and the mounting plate 2.1 are driven to drive the left and right sliding blocks 2.2 and 2.2 'to slide along the left and right guide rails 1.2 and 1.2', so that the pushing device 3, the swinging device 4, the electromagnet 5 and the base plate III which are mounted on the gear shaft are driven to move.

When the position of the base plate III needs to be adjusted through the pushing device 3, the pushing speed reducing motor 3.1 drives the pushing gear shaft 3.3 to rotate, a gear of the pushing gear shaft 3.3 is meshed with the pushing rack 3.10, so that all parts of the swinging device 4 except the swinging mounting seat 4.6 are driven to move along the axial direction of the rotating shaft 4.7, and the base plate III is finally driven to move.

When the position of the base plate III needs to be adjusted through the swinging device 4, the swinging speed reduction motor 4.1 drives the rotating shaft 4.7 to rotate, so that the bevel gear 4.11 is driven to rotate. Because the bevel gear 4.11 is meshed with the bevel gear on the swing shaft arm 4.15, the swing shaft arm 4.15 can rotate around the axes of the upper swing device spacer bush 4.14 and the lower swing device spacer bush 4.14', and the purpose of adjusting the position of the cushion plate III through the swing device 4 is achieved.

After the backing plate III is placed at a required angle and position by adjusting the transverse moving device 2, the pushing device 3 and the swinging device 4, the electromagnet 5 is powered off, and the gear type automatic placing device for the backing plate of the flatting machine is retracted into the space between the front and rear upright posts I and II and between the front and rear upright posts I and II' of the flatting machine.

Similarly, when backing plate III is required to be withdrawn, electromagnet 5 can be moved to the position of backing plate III under the combined action of transverse moving device 2, pushing device 3 and swinging device 4, electromagnet 5 is electrified, and backing plate III is withdrawn to the space between front and rear upright posts I, II and I 'and II' of the flatting machine.

The technical solutions in the present invention are clearly and completely described, and all other solutions obtained by those skilled in the art without creative efforts based on the solutions in the present invention belong to the protection scope of the present invention.
