Description

Technical Field

[0001] The present invention relates to the technical field of steel strip welding machines, and in particular to a fully automatic steel strip welding device. Background Art

[0002] Roll forming is a widely used cold deformation processing technology. Most roll forming production lines use coiled steel strips as raw materials, and the strip materials are processed into strip products with different cross-sections through the roll forming of multiple sets of roller wheels. During the continuous production process, after each coil of steel strip is used up, a new steel strip needs to be replaced, and the new and old steel strips need to be welded together. The common method for existing steel strip welding is as follows: Manual or semi-automatic shearing butt welding machines are used to splice the head of the new steel strip and the tail of the old steel strip, and then welding is carried out. The main existing problems are as follows: 1. Two operators are required to be responsible for aligning and fixing the heads and tails of the new and old steel strips respectively for manual splicing of the head and tail and welding, and another welder is required for welding, which requires a large number of operators and takes a long time; 2. Ordinary semi-automatic shearing butt welding equipment has problems such as uneven trimming of the head and tail edges and misalignment during butt joint, and frequently there are phenomena such as dislocation at the butt joint of the steel strip, too small or too large gap, resulting in frequent occurrence of weld opening or weld quality not meeting the requirements, and manual intervention for rework is required, affecting the normal production rhythm. Summary of the Invention

Detailed implementation manners

[0016] The present invention will be further described below in conjunction with the accompanying drawings and detailed implementation manners:

[0017] As Figures 1 to 2 shown, a fully automatic steel belt welding device, characterized in that it includes: a fuselage 1, a feeder 2 is provided on the left side thereof, a workpiece pressing transmission mechanism 3 is provided on the right side of the fuselage 1, a bracket 4 is provided in the middle of the fuselage 1, a fixed-distance feeding mechanism 5 capable of conveying materials at a fixed distance is symmetrically provided on the fuselage 1, air scissors 6 are symmetrically provided on the fuselage 1, a welding walking mechanism 7 capable of welding materials is provided on the bracket 4, a control box 15 is provided on one side of the fuselage 1, a status indicator light 16 is provided on the fuselage 1, and an air storage tank 14 is provided below the right side of the fuselage 1.

[0018] For a fully automatic steel belt welding device with the above structure, during welding, the old steel belt material head is guided by the feeder 2 to the fixed-distance feeding mechanism 5 on the left side. At this time, the new steel belt material head moves to the respective fixed-distance feeding mechanisms 5 on the right side through the workpiece pressing transmission mechanism 3. Then, the old steel belt material head and the new steel belt material head are clamped by the fixed-distance feeding mechanisms 5 on the left and right sides respectively. At the same time, the butt joint of the old steel belt material head and the new steel belt material head is sheared by the air scissors 6 to make it flat. Then, the fixed-distance feeding mechanism 5 moves and butts the old steel belt material head and the new steel belt material head. Finally, the butt joint of the old steel belt material head and the new steel belt material head is welded by the welding walking mechanism 7. Compared with the prior art, it can automatically align the old and new steel belt material heads, automatically weld the old and new steel belts, and can cut the material head and tail to avoid the weld quality not meeting the requirements.

[0019] As Figure 2As shown, in some embodiments of the present invention, the workpiece pressing and transmission mechanism 3 includes a mounting bracket 31 fixed to the right side of the fuselage 1. An upper transmission roller 32 and a lower transmission roller 33 are respectively arranged on the upper and lower sides of the mounting bracket 31. A pressing air cylinder 34 is arranged on the mounting bracket 31. The output end of the pressing air cylinder 34 is fixedly connected to the upper transmission roller 32. The lower transmission roller 33 is movably sleeved under the mounting bracket 31. A reduction motor 35 is connected to the front side of the lower transmission roller 33.

[0020] For a fully automatic steel belt welding device with the above structure, to prevent the sheet material from not being transported after the uncoiler finishes unwinding the coil material, or the sheet material falling into the buffer pit under its own weight. After the uncoiler finishes unwinding the steel plate, the upper transmission roller 32 presses down on the lower transmission roller 33 through the pressing air cylinder 34, so that the steel plate is squeezed between the upper transmission roller 32 and the lower transmission roller 33. During transportation, the lower transmission roller 33 is driven to rotate by the reduction motor 34. The reduction motor 34 is a variable frequency motor for adjusting the motor speed to realize the adjustment of the sheet material transportation speed, and the adjustment range is 500 mm to 13000 mm. A speed regulation knob is arranged on the control box 15. The upper transmission roller 32 can move up and down under the action of the pressing air cylinder 34. When not pressing tightly, the upper transmission roller 32 is located at the upper end, and at this time the material can pass smoothly between the two rollers. When pressing tightly is required, the upper transmission roller 32 is located at the lower end, and the material is pressed tightly under the action of the pressing air cylinder 34.

[0021] As Figure 1 and 2 As shown, in some embodiments of the present invention, the fixed-distance feeding mechanism 5 includes guide rods 51 symmetrically fixed to the left and right sides of the fuselage 1. A feeding slide seat 52 is inserted between every two guide rods 51. A plurality of feeding pressing air cylinders 53 are fixed on each feeding slide seat 52. A plastic pressing hoof 54 is fixed to the output end of each feeding pressing air cylinder 53. Feeding air cylinders 55 are symmetrically fixed above the fuselage 1. Each feeding slide seat 52 is connected to the adjacent feeding air cylinder 55.

[0022] For a fully automatic steel belt welding device with the above structure, seven feeding pressing air cylinders 53 with a cylinder diameter of 40 mm are installed on the feeding slide seat. A plastic pressing hoof 54 is installed at the piston rod end of the pressing air cylinder 53 to press the material tightly. When it is necessary to drive the material to move, the feeding air cylinder 55 drives the feeding slide seat 52 to move along the guide rod 51 to realize the forward and backward movement of the feeding slide seat 52 and realize the fixed-distance transportation of the material. The feeding end position is adjustable.

[0023] As Figure 2As shown, in some embodiments of the present invention, the welding traveling mechanism 7 includes a linear movement module 71 fixed to the bracket 4. A welding cylinder 72 is fixed to the moving end of the linear movement module 71. A chromium zirconium copper welding wheel 73 is fixed to the output end of the welding cylinder 72. A welding transformer 74 is provided on the linear movement module 71. A lower electrode assembly 75 is fixedly provided in the middle of the fuselage 1.

[0024] For a fully automatic steel strip welding device with the above structure, the welding transformer 74 is controlled by a resistance welding controller. During welding, the welding cylinder 72 and the welding transformer 74 move through the linear movement module 71. The welding cylinder 72 can push the chromium zirconium copper welding wheel 73 towards the butt joint of the material. The electrode assembly 75 cooperates with the chromium zirconium copper welding wheel 73 to achieve welding. The chromium zirconium copper welding wheels 73 are two and adopt the single-sided double-point method to weld two weld seams at a time.
