For realizing this purpose, the laser weld zero degree wire feed equipment that the utility model is designed, it comprises casing, be arranged on five-roll machine structure in the casing, be arranged on driving mechanism under the five-roll machine structure, be arranged on the mouth of leading under the driving mechanism, and be arranged on the welding wire transfer control that driving mechanism one side is used to control its action, its special character is: the top of described five-roll machine structure is provided with welding wire wheel, and the installation site of described welding wire wheel is with so that welding wire is vertically led mouth by entering behind five-roll machine structure and the driving mechanism.
Described five-roll machine structure is formed by being mutual vertically arranged first group of five-roll machine and second group of five-roll machine.
Described driving mechanism has a pair of welding wire and transmits drive motors, and this is provided with the welding wire hold down gag in the middle of welding wire is transmitted drive motors, and this transmits the drive motors below to welding wire and is provided with welding wire speed of travel checkout gear.
Described below of leading mouth is connected with welding wire and transmits flexible pipe.
Advantage of the present utility model is: the utility model is by being set directly at the welding wire wheel top of five-roll machine structure; make welding wire in the wire feed process, keep straight line; the wire feed rate of equipment has been accelerated in such design; make wire feed more even; reduced the possibility that welding seam breaking takes place and cause disorderly closedown; improved welding quality, made welding equipment energy throat thickness greater than 4.2mm, si content height and other special steel grade.
