Has the welded mesh of preventing sheet deformation mechanism on the welding machine of mesh
Technical field
What the present invention relates to is welding machine of mesh, particularly be to have the welded mesh of preventing sheet deformation mechanism on the welding machine of mesh.
Background technology
At present, welding machine of mesh is to require the reinforcing bar of horizontal and vertical arrangement is welded the equipment that forms the net sheet automatically according to design size.The welding machine of mesh of prior art in the course of the work, welding electrode can produce bigger heat, and this heat is delivered to reinforcing bar very soon, causes soldered net sheet also to become awfully hot, torsional deformation appears in the net sheet after the thermal deformation, and the filamentary webs sheet distortion after particularly the less reinforcing bar of diameter welds is more obvious.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of transverse steel two ends to be respectively arranged with to clamp the manipulator of transverse steel of stretching round about simultaneously, reduce on the welding machine of mesh of net sheet thermal deformation and have the welded mesh of preventing sheet deformation mechanism in welding machine of mesh bottom electrode both sides.
The technical scheme that solves the problems of the technologies described above is: have the welded mesh of preventing sheet deformation mechanism on a kind of welding machine of mesh, having the welded mesh of preventing sheet deformation mechanism on the described welding machine of mesh comprises: manipulator, reinforcing-bar clamping machine structure, transverse steel two ends on the welding machine of mesh bottom electrode are connected to an end of reinforcing-bar clamping machine structure, the other end of reinforcing-bar clamping machine structure connects the manipulator that transverse steel is stretched simultaneously round about, this manipulator connection control system respectively.
The invention has the beneficial effects as follows: the present invention utilizes manipulator that the transverse steel on the bottom electrode is clamped, and then stretches round about simultaneously, carries out the welding instruction.After the welding of vertical, horizontal reinforcing bar finishes, the release mechanism hand, such action finishes, and repeats same action again on next root transverse steel.Manipulator of the present invention can prevent the distortion of net sheet effectively by the instruction of manipulator connection control system execution clamping and release, and the net tablet quality improves, and disqualification rate reduces, and has saved manufacturing cost.The motion of described manipulator can be the mechanical motion mechanism of eccentric ratio,

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
The invention provides and have the welded mesh of preventing sheet deformation mechanism on a kind of welding machine of mesh, have the welded mesh of preventing sheet deformation mechanism on the described welding machine of mesh and comprise: manipulator, reinforcing-bar clamping machine structure.Transverse steel 6 two ends on the welding machine of mesh bottom electrode 7 are connected to an end of reinforcing-bar clamping machine structure 2, and the other end of reinforcing-bar clamping machine structure 2 connects the manipulator that transverse steel 6 is stretched simultaneously round about respectively, this manipulator connection control system (figure does not show).
As shown in Figure 1, described manipulator is a Pneumatic manipulator, and its structure comprises: cylinder 5, guide rail 4, substrate 3; Piston rod 9 on the described cylinder 5 is connected substrate 3 one ends, being arranged on the guide rail 4 of the basal sliding of this substrate 3; The other end at the fixedly connected reinforcing-bar clamping machine structure 2 of substrate 3 other ends.
As shown in Figure 2, described manipulator is a hydraulic efficiency manipulator, and its structure comprises: hydraulic cylinder 15, guide rail 4, substrate 3; Piston rod 19 on the described hydraulic cylinder 15 is connected substrate 3 one ends, being arranged on the guide rail 4 of the basal sliding of this substrate 3; The other end at the fixedly connected reinforcing-bar clamping machine structure 2 of substrate 3 other ends.
As shown in Figure 3, described manipulator is an eccentric rod gear, and its structure comprises: motor 23, connecting rod 21, cam 22; Described cam 22 is connected on motor 23 output shafts; One end of connecting rod 21 is fixed on cam 22 and sets eccentric parts, and the other end of connecting rod 21 is fixed on substrate 3 one ends, being arranged on the guide rail 4 of the basal sliding of this substrate 3; The other end at the fixedly connected reinforcing-bar clamping machine structure 2 of substrate 3 other ends.
Described reinforcing-bar clamping machine structure 2 is gas pawls or has the part that clamps function.Above-mentioned gas pawl is the standard clamping element of selling on market.
