Technical Field
The invention relates to the technical field of production of stainless steel composite plates, in particular to a pressure device for welding a substrate and a cover plate.
Background
The stainless steel composite plate is a composite plate steel plate formed by combining a carbon steel substrate and a stainless steel cover plate or combining different series of stainless steel substrates and cover plates. It is mainly characterized by that the carbon steel and stainless steel are formed into firm metallurgical combination, and can be undergone the processes of hot-pressing, cold-bending, cutting and welding, etc., so that it possesses good technological properties.
At present, three methods are mainly used for industrial production of stainless steel composite plates, namely an explosion cladding method, a hot rolling cladding method and a cold rolling cladding method. The explosion cladding method is that the covering plate is overlapped on the base plate, and a certain distance is formed between the covering plate and the base plate by adopting a cushion interval. The explosive is spread on the surface of the clad plate, and the energy of explosive explosion makes the clad plate impact the substrate at high speed to generate high temperature and high pressure so as to realize solid-phase welding of the interface of the two materials. The hot-rolled composite plate is formed by rolling a base plate and a clad plate in a physically pure state under a high vacuum condition, and the two metals are diffused in the rolling process to realize complete metallurgical bonding. The cold rolling compounding method is to produce stainless steel composite sheet (coil) with thickness below 5mm through acid washing, cold rolling, acid washing (or bright annealing), leveling, drawing and straightening and other production processes on the basis of the hot rolling compounding method.
The explosion cladding method utilizes the energy of the explosive to produce, causes vibration, noise and smoke pollution to the environment, and is limited by weather and other process conditions, so the production efficiency is low. Therefore, hot rolling and cold rolling are most commonly used.

At present, a multi-point pressing mode is generally adopted to perform multi-point pressing on base plates and covering plates which are stacked together, namely, a combined blank plate, and the positions of all pressing points are fixed and cannot be adjusted, so that the requirement of pressing the combined blank plates with different lengths and widths cannot be met.

In the present invention, each traverse frame includes an upper moving block 31 and a lower frame-shaped frame 32 connected by a vertical beam 33 and arranged in the width direction of the frame.
Therefore, on the premise of ensuring that each transverse moving frame has reasonable strength, the self weight of each transverse moving frame can be reduced, so that the transverse moving can be conveniently carried out according to actual use requirements, and the purpose of adjusting the position of a pressure applying point is achieved.
In the invention, two mounting blocks 5 are fixedly connected to both sides of an upper moving block 31 at the top end of a rack 1, a screw rod 6 arranged along the length direction of the rack 1 is rotatably mounted between the two mounting blocks positioned at one side, one end of the screw rod 6 extends out of the mounting block, and a speed reduction motor 7 in transmission connection with the extending end of the screw rod 6 is mounted at the top end of the rack 1; a guide rod 8 arranged along the length direction of the frame 1 is fixedly connected between the two mounting blocks positioned at the other side, one side of the upper moving block 31 is arranged on the screw rod 6 through thread fit, and the other side of the upper moving block 31 is arranged on the guide rod 8 through sliding fit.

The width of the mobile platform 2 is slightly less than that of the rack 1, and on the premise that the wider combined blank plate is pressed and welded as far as possible, the mobile platform 2 can penetrate through the rack 1.
