The utility model discloses a steel core reinforced FRP pultruded section breaking and cutting device, and relates to the technical field of cutting equipment, the steel core reinforced FRP pultruded section breaking and cutting device comprises a rack, the inner bottom wall of the rack is provided with a section conveying piece, the inner top wall of the rack is fixedly connected with an electric push rod in an inserted mode, and the extending end of the electric push rod is fixedly provided with an adjustable double-head cutting piece. The adjustable double-head cutting piece is blocked through the blocking frame, so that the possibility that the adjustable double-head cutting piece directly cuts a cutter steel core is reduced, the two cutter heads of the adjustable double-head cutting piece are used for cutting the steel core and FRP respectively, the loss increase of the cutter heads is reduced, and the possibility that the FRP part on a sectional material is ablated and blackened is reduced; the first motor drives the rotating disc to rotate to control the section bar to rotate, when the two side plates expand, the hinge rod is promoted to be unfolded, the two section bar conveying cylinders are pulled to contract, and therefore the section bar is clamped through the section bar conveying cylinders so that the section bar can be conveyed conveniently, and the section bar is more convenient to rotate and convey.

This invention relates to the field of laser cutting technology and discloses a laser cutting device for copper plates used in copper crafts processing. The device includes a laser cutting machine housing and a laser cutting head. Y-axis linear motors are mounted on both sides of the top of the laser cutting machine housing, and a portal frame is positioned between the Y-axis linear motors. An X-axis linear motor is fixed to one side of the top beam of the portal frame. The laser cutting head is fixed to one end of the slide. A fixing ring is fixed to the lower half of the outer wall of the laser cutting head, and an external gear ring is fixed to the outside of the fixing ring. This invention achieves a 360° adjustable preheating and rapid cooling mechanism around the laser cutting head, allowing it to follow the cutting direction of the laser cutting head in real time. This ensures that the electric heating plate always precisely covers the area to be cut, and the hollow water-cooled housing always precisely covers the cutting area, achieving seamless integration of preheating, cutting, and rapid cooling. This maximizes the effects of preheating and rapid cooling, further improving cutting accuracy and cut quality.
