Problems solved by technology

This patent only realizes the automation of the blanking process of section steel processing
In addition, in the process of section steel production, it is impossible to complete the continuous operation of each process, but requires step-by-step processing, and the degree of automation is not high; at the same time, step-by-step processing also increases the production area, which is not conducive to the improvement of production efficiency; at the same time, section steel During the production process, the steel plate needs to be cut, and the processed steel plate needs to be welded before it can be formed. The flue gas generated by cutting and welding lacks corresponding purification procedures.

Embodiment 1

[0039] Embodiment 1: with reference to attached figure 1 , a production method of automatic submerged arc welding H-shaped steel, the improvement is: comprising the following steps:

[0040] S1. Feeding: use the gantry crane to hoist the steel plates to the lifting platforms of the upper and lower flange plates and web plates respectively;

[0041]S2. Push cutting of the upper flange plate: the large pusher bar pushes the steel plate to the predetermined position, and the fixed size is the width of the upper flange plate from the cutting edge to the edge of the plate. The plasma cutting trolley cuts, and the large pusher bar continues to move forward Push the steel plate, and the plasma cutting trolley cuts again, and pushes and cuts in this way until the cut upper flange plate is pushed to the predetermined position of the upper flange plate conveying platform;

[0042] S3. Conveying of the upper flange plate: the small push plate in the upper flange plate conveying platform...

Embodiment 2

[0055] Embodiment 2: On the basis of Embodiment 1, in S1, the lifting platform is controlled by a drive motor, a reducer, a steering gear and an elevator, so as to adjust the height of the steel plate and push the steel plate.

Embodiment 3

[0056] Embodiment 3, on the basis of Embodiment 1 or 2, in S2, after the steel plate is lifted to a predetermined height by the lifting platform, the large pusher pushes the steel plate to a distance from the edge of the plate under the drive of the motor and the lead screw. The cutting position of the width of the upper flange plate is cut out by the plasma cutting trolley to a predetermined width of the upper flange plate; each time a piece of the upper flange plate is cut, the push bar continues to push the steel plate forward to the width of an upper flange plate, Cutting again; in the process of pushing the upper flange plate, push the cut upper flange plate to the upper flange plate conveying platform one after another;

[0057] In S4, after the steel plate is lifted to a predetermined height by the lifting platform, the large pusher pushes the steel plate to the cutting position of one web width away from the edge of the plate under the drive of the motor and the lead sc...

Abstract

The invention relates to an automatic submerged-arc welded H-shaped steel production method. The method comprises the following steps of feeding, upper flange plate pushing and cutting, upper flange plate conveying, web pushing and cutting, web turning over, upper flange plate secondary conveying, T-shaped steel automatic welding, lower flange plate pushing and cutting, lower flange plate conveying, T-shaped steel conveying, T-shaped steel turning over, lower flange plate secondary conveying, H-shaped steel automatic welding, finished product conveying, and finished product stacking and packaging; and feeding is conducted through a portal crane, the steel is cut through a plasma cutting trolley, steel plates and finished products are conveyed, stacked and packaged through a conveying platform, a finished product conveying system, a finished product stacking and packaging system. The automatic submerged-arc welded H-shaped steel production method has the advantages of being easy and convenient to operate, stabile in connection and capable of achieving continuous automatic production.

Description

technical field [0001] The invention relates to the field of profile processing, in particular to a production method for automatic submerged arc welding of H-shaped steel. Background technique [0002] Automated machinery is widely used in various fields of social production. In the field of section steel production for steel plate processing and forming, the application of automated production technology is mainly concentrated in a specific production process. For example, Chinese Patent No. CN204171508U discloses a H-shaped steel blanking device, which includes a workbench, double beams Semi-gantry cranes, lifting beams, gantry, flame cutting machines, unloading racks and steel belts and other components can be set to meet the height requirements of cutting webs and wings by setting up and down liftable beams, and the gantry can be dragged by setting movable steel belts Realize horizontal movement, and then drive 6 flame cutting machines to realize horizontal cutting und...
