Description

Rectangular slab turning mechanism

technical field

The invention belongs to the technical field of composite board production equipment, and in particular relates to a rectangular slab turning mechanism.

Background technique

Composite panels are made of carbon steel or low-alloy steel as the base layer and special materials such as stainless steel and titanium steel as the composite layer. In the fields of metallurgy and petrochemical industry.

At present, the traditional composite panel production mainly adopts the explosion method, which will cause vibration to the environment, resulting in noise and smoke pollution. At the same time, the process is also easily affected by weather factors, resulting in unstable production cycle and output.

The vacuum rolling method is to make the base layer of carbon steel or low alloy steel and the multilayer of special materials such as stainless steel and titanium steel after blanking and surface treatment to make the surface in a physically pure state, and then roll it under high vacuum conditions. The problem of environmental pollution is effectively avoided, and at the same time, the production process of the vacuum rolling method greatly improves the production efficiency of the composite plate.

The purpose of controlling the high vacuum condition in the vacuum rolling method is to prevent the oxidation of the hot-rolled interface from reducing the bonding strength and bonding rate of the interface. One of the methods uses submerged arc welding to weld the rectangular slab around the interface, and then vacuumizes the hot-rolled interface. When the hot-rolled interface is always in a high vacuum state, the hot-rolled interface is hardly oxidized, thus greatly improving the interface. Combine performance.

When submerged arc welding is used to weld the rectangular slab around the joint interface, the joint interface of the rectangular slab is on the side, so it can only be welded by horizontal welding. Since the horizontal welding will cause the liquid solder to flow downward due to gravity and spreading, not only the solder is wasted, but also there may be leaks in the weld, which will cause subsequent vacuum failure, so it is necessary to change the horizontal welding into a flat welding, so that the rectangular plate The bonding interface of the slab faces upward, and at the same time, the rectangular slab can be rotated 90° sequentially so that each side faces upward in turn to complete the welding.

Due to the heavy weight of the rectangular slab, it is difficult for the existing turning machine to stand up the rectangular slab and then rotate the rectangular slab forward or reverse 360° in the vertical plane, so that the bonding interface of the rectangular slab Welding around is inconvenient.

Contents of the invention

The technical problem to be solved by the present invention is to provide a rectangular slab turning mechanism to solve the problem that the existing turning machine is difficult to erect the rectangular slab, and then make the rectangular slab forward or reverse in the vertical plane. The 360° rotation brings inconvenience to the welding around the bonding interface of the rectangular slab.

In order to solve the above-mentioned technical problems, the technical solution of the present invention is: the rectangular slab turning mechanism includes a frame, and a turning shaft is fixedly connected to the turning shaft, and the turning shaft driven by the first power device is rotatably installed on the turning shaft. The casing, the rotating shaft driven by the second power device is installed in the flipping casing, the rotating shaft and the flipping shaft are vertically arranged, and the end of the rotating shaft is fixedly connected with a Clamping table for slabs.

As an improvement, the clamping table includes a base connected to the rotating shaft, and several clamping blocks for clamping the long side and the short side of the rectangular slab are slidably installed on the base, each Each of the clamping blocks is connected to a third power device.

As a further improvement, the several clamping blocks are arranged in pairs and distributed symmetrically.

As a further improvement, the clamping block includes a positioning part for supporting the bottom surface of the rectangular slab, and a clamping part driven by a fourth power device is slidably installed on the positioning part.

As a further improvement, the second power device includes a worm-gear transmission mechanism driven by a hydraulic motor, and a worm gear of the worm-gear transmission mechanism is fixedly connected to an end of the rotating shaft opposite to the clamping table.

As a further improvement, there are two rectangular slab turning mechanisms.

After adopting the above-mentioned technical solution, the beneficial effect of the present invention is that: since the rectangular slab turning mechanism includes a turning shaft, the turning casing driven by the first power device is rotatably mounted on the turning shaft, and the turning casing is rotatably installed There is a rotating shaft driven by the second power device, the end of the rotating shaft is fixedly connected with a clamping table, after the rectangular slab is hoisted to the clamping table by a crane, the clamping table clamps the rectangular slab, the first The power device drives the turning shell to rotate 90° around the turning axis, and the turning shell drives the clamping table and the rectangular slab to turn 90°, that is, the rectangular slab stands up at this time, and the weld seam of the rectangular slab is welded by submerged arc welding; welding is completed Finally, the second power unit drives the rotating shaft to rotate 90° sequentially, and the rotating shaft drives the clamping table and the rectangular slab to rotate 90° sequentially in the vertical plane, so that the other sides of the rectangular slab face up, which is convenient for submerged arc welding. The slab, thus realizing the erection of the rectangular slab, and then making the rectangular slab rotate forward or reverse 360° in the vertical plane, which greatly facilitates the welding around the joint interface of the rectangular slab.

Since the clamping table includes a base connected to the rotating shaft, several clamping blocks for clamping the long side and the short side of the rectangular slab are slidably installed on the base, each of the clamping The clamping blocks are all connected to a third power device, so driven by the third power device, the clamping block can quickly clamp the rectangular slab, which greatly improves the production efficiency; at the same time, because each clamping block is connected to a first Three power devices, when welding the rectangular slab joint interface, the clamping block driven by the third power device on the top surface of the rectangular slab is loosened at this time, and the welding torch is retreated, so that the surroundings of the rectangular slab joint interface can be completely welded to prevent Clamp block interferes with welding torch.

Since the several clamping blocks are arranged in pairs and distributed symmetrically, the force on the rectangular slab is uniform, preventing the rectangular slab from occurring when the clamping block clamps the rectangular slab due to uneven force. tilted, resulting in poor welding.

Since there are two rectangular slab turning mechanisms, that is, double stations, two rectangular slabs can be welded at the same time, which further improves production efficiency.
