The invention relates to an environment-friendly building exterior wall decorative plate and its installation method, comprising a fixing frame, a positioning device and a plate body, the fixing frame is installed on the keel frame through screws, the fixing frame has an L-shaped structure, and the upper end of the fixing frame A reinforcing plate is installed between the keel frame, and the number of fixing frames is two. A positioning device is installed on the fixing frames, and a plate body is installed between the right ends of the positioning frames. The present invention can solve the problem of poor installation effect, inconvenient installation and disassembly of the existing exterior wall decoration boards, large gaps between the installed boards, and rainwater easily seeping into the boards, affecting the subsequent use of the boards In addition, when the existing decorative panels for exterior walls are used, the use effect of the panels is poor, the protective performance is low, the decorative layer of the panels is prone to breakage, and the broken panels are prone to fall off, which affects the safety of use and other problems.

The invention relates to the field of bimetallic saw strip machining, in particular to welding equipment and welding method for bimetallic band saw strips. The welding equipment comprises a laser generator, a base material supplying slide rail, a pre-welding position alignment device, a main controller, an upper fixture device and a lower fixture device, wherein the upper fixture device and the lower fixture device are symmetrically arranged up and down, the laser generator is arranged at the downstream end of the base material supplying slide rail, the upper fixture device and the lower fixture device are located above and below the base material supplying slide rail correspondingly, the back side of the base material supplying slide rail is provided with a power device, the front side and the back side of the base material supplying slide rail are each provided with one clamping device, and the pre-welding position alignment device can be movably arranged at the end portion of the downstream end of the base material supplying slide rail through an avoidance air cylinder and is further in electrical connection with the main controller. By means of the welding equipment and weldingmethod for the bimetallic band saw strips, two pre-welding base materials can be effectively clamped and positioned, and then the welding quality is improved, in addition, a rubber shaft sleeve and arubber sleeve which are in direct contact with the base materials can both be detachably arranged, and the fixture maintenance cost is greatly lowered.

The invention belongs to the technical field of machining of a middle trough of a scraper conveyor, and particularly relates to a specialized automatic assembly welding machine tool for the middle trough. The specialized automatic assembly welding machine tool comprises a rack, wherein a front clamping location device, an automatic welding device I, a lifting turnover device, an automatic welding device II and a rear clamping location device are sequentially arranged on the upper edge of the rack in a middle trough machining moving direction; the front clamping location device comprises one column of middle plate supporting rollers, two columns of middle trough supporting rollers, a trough ledge side face clamping location mechanism, an overturn type trough ledge end ditch clamping location mechanism, a middle plate front and back clamping location mechanism and a middle plate top pressing mechanism; and the automatic welding device I / II comprise welding supports arranged along the two sides of the rack, welding guns, wire feeders, welding wire winding drums, welding support longitudinal moving mechanisms, welding gun and wire feeder lifting moving mechanisms, welding gun and wire feeder transverse moving mechanisms and welding wire winding drum lifting supporting mechanisms. The specialized automatic assembly welding machine tool can improve working performance and welding quality and reduces labor intensity of workers.
