Description

Technical Field

[0001] This invention relates to the field of H-beam welding equipment, specifically to a horizontal automatic welding equipment for H-beams with a straightening mechanism. Background Technology

[0002] H-beams are an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. H-beams have advantages such as strong bending resistance, simple construction, cost savings, and light structural weight. Therefore, H-beams are widely used in the load-bearing of factory buildings. Thus, it is very important to straighten and weld H-beams during the manufacturing process.

[0003] When welding H-beams on the market, the steel plates are usually supported manually, which can easily cause the weld to deviate from the intended welding position or even bend, failing to meet the parallelism requirements of the H-beams and affecting product quality. Furthermore, existing H-beam production lines on the market are custom-made. If different specifications of H-beams need to be processed, the production line may need to be replaced or extensively modified, which will increase costs and reduce productivity. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a horizontal automatic welding equipment for H-beams with a straightening mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] Preferably, the lower H-plate straightening mechanism includes a lower side plate, a straightening roller mechanism, and an electronic dial indicator. The lower side plates are arranged on both sides of the lower H-plate straightening mechanism. Four pairs of electronic dial indicators, four pairs of straightening roller mechanisms, and one pair of infrared rangefinders are symmetrically arranged on the side walls of the two lower side plates. The four pairs of electronic dial indicators on the lower H-plate straightening mechanism are symmetrically arranged at both ends of the lower side plates.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this invention, the correction roller mechanism and the electronic dial indicator are used in conjunction with the correction roller mechanism set in the upper H-plate correction mechanism. The correction roller mechanism measures the error of the horizontal amplitude of the wing plate through the electronic dial indicator and transmits it to the control box. According to the result measured by the electronic dial indicator, the control box outputs an electrical signal to control the electric pressure rods of the four pairs of correction roller mechanisms. The electric pressure rods then adjust different pressure rod forces according to the electrical signal output by the control box, so that the horizontal error of the wing plate is corrected. Compared with manually supporting and adjusting the horizontal error of the wing plate, the correction roller mechanism can not only clamp wing plates of different thicknesses, but also correct the horizontal error of the wing plate.

[0016] 2. In this invention, the electric straightening roller mechanism and the electronic dial indicator are used in conjunction with the electric straightening roller mechanism in the middle H-plate straightening mechanism. The electronic dial indicator on the middle H-plate straightening mechanism measures the error of the vertical amplitude of the web plate and transmits it to the control box. According to the result measured by the electronic dial indicator, the control box outputs an electrical signal to control the electric rods of the four pairs of electric straightening roller mechanisms. The electric rods then adjust the angle of the web plate according to the electrical signal output by the control box, so that the web plate always remains relatively perpendicular to the flange. Compared with manual support welding, the error when welding the web plate and flange plate is greatly reduced.

[0017] 3. In this invention, the straightening carriage mechanism and the infrared rangefinder are set in the lower H-plate straightening mechanism. Two pairs of infrared rangefinders are respectively set on both sides of the wing plate. The distance error between the front and rear wing plates and the side plate in the horizontal position is measured and transmitted to the control box. The control box controls the rotation angle of the rotating motor table on the front and rear straightening carriage mechanisms. The conveyor belt abuts against the wing plate to finely adjust its horizontal error distance, so that the wing plate is aligned in position during welding, and the welding error is greatly reduced.

[0018] 4. In this invention, by setting a bottom plate adjustment mechanism in the lower H-plate straightening mechanism, when it is necessary to process wing plates of different widths, the infrared rangefinder measures the width of the wing plate, and the control box adjusts the electric push rod of the bottom plate adjustment mechanism. The push rod pushes the side plate so that the straightening roller mechanism can clamp and fix the wing plate. Compared with the existing setup that requires adjusting the production line specifications and changing the setup when processing H-steels of different specifications, the bottom plate adjustment mechanism can quickly adjust the production line for processing H-steels to the required specifications without changing the production line, reducing cost input and greatly improving production efficiency.

The bottom plate adjustment mechanism 7 can process wing plates of different specifications and widths without changing the production line when wing plates of different specifications are placed.The infrared rangefinder 15 measures the width of the wing plate. The control box 14 adjusts the electric push rod 703 of the base plate adjustment mechanism 7. The electric push rod 703 pushes the side plate. When the straightening roller mechanism 8 can just clamp the wing plate to the fixed position, the electric push rod 703 stops pushing the side plate. The electric pressure rod 802 in the straightening roller mechanism 8 presses down, and the upper pressure roller 803 abuts against and fixes the wing plate. Compared with the existing setup, which requires adjusting the production line specifications and changing the setup when processing H-beams of different specifications, the base plate adjustment mechanism 7 can quickly adjust the production line for processing H-beams to the required specifications without changing the production line, reducing cost input and greatly improving production efficiency.
