Description

Technical Field

[0001] The utility model relates to the technical field of metal heat treatment, in particular to a production line for large-scale medium and thick plate metal heat treatment. Background Art

[0002] Metal heat treatment is a process method in which a metal workpiece is heated to a certain temperature, kept warm for a period of time, and then cooled to room temperature at a specific speed. This treatment method does not change the size and overall chemical composition of the workpiece, but can change the internal structure of the workpiece or the chemical composition of the workpiece surface, thereby improving the intrinsic quality of the workpiece and meeting specific performance requirements. The purpose of metal heat treatment is to control the performance of metal materials by changing their surface or internal structure. When heat treating metal plates, electromagnetic heating technology is mostly used. The metal plates are transported to the electromagnetic heating chamber through a conveyor line, and multi-stage electromagnetic heating is used in the electromagnetic heating chamber. The heating of the metal plates is more uniform and more efficient. However, since the electromagnetic coils are fixedly interspersed between the rollers of the conveyor line, when the metal plate is offset on the conveyor line, the metal plate is easily in direct contact or collision with the electromagnetic coil, which in turn affects the heating of the metal plate. To this end, we provide a large-scale medium and thick plate metal heat treatment production line to solve the above problems. Utility Model Content

[0003] In order to solve the above problems, that is, to solve the problems raised by the above background technology, the utility model proposes a large-scale production line for heat treatment of medium and thick plate metals, including a frame, a conveyor line is laid on the top of the frame, an electromagnetic heating chamber is arranged above the frame in the middle section of the conveyor line, the conveyor line includes a plurality of rollers for conveying workpieces, the conveyor line is located on the outside of the electromagnetic heating chamber, and a rod body is arranged correspondingly between every two rollers, the outer wall of the rod body is rotatably provided with a groove block, the groove block is fixedly arranged on the inner wall of the frame, the top of the rod body is provided with a rocker, the inner cavity of the frame is parallelly provided with two sliding rods along the length direction, the outer wall of the sliding rod is slidably provided with a slide plate, the two slide plates are driven and controlled by a driving device, the bottom end of the rod body is fixedly provided with an outer cylinder, the inner cavity of the outer cylinder is slidably provided with an inner rod, and one end of the inner rod is rotatably connected with the slide plate through a pin shaft.

A connecting plate is fixedly provided at the movable end of the cylinder, and both ends of the connecting plate are fixedly connected to the two slides respectively.

[0006] Preferably, the limiting end of the rocker is configured to be spherical.

The two slides 8 are driven and controlled by a driving device. An outer cylinder 9 is fixedly provided at the bottom end of the rod body 4. An inner rod 10 is slidably provided in the inner cavity of the outer cylinder 9. One end of the inner rod 10 is rotatably connected with the slide 8 through a pin shaft. The rocker 6 is located above the roller body, and the driving component can drive the slide 8 to move horizontally. The slide 8 can drive the rod body 4 to rotate through the sliding connection between the outer cylinder 9 and the inner rod 10, and the rotating rod body 4 can drive the rocker 6 to swing. The two relatively swinging rockers 6 can control the spacing of the metal plates transported on the conveyor line 2, thereby ensuring the stability of the conveyor line 2 when transporting metal plates and avoiding the phenomenon of deviation.

[0015] Specifically, a slot 13 is provided inside the rocker arm 6, and an insertion rod 14 is slidably provided in the inner cavity of the slot 13. The insertion rod 14 is fixedly connected to the outer wall of the rod body 4. A bolt 15 is threadedly connected to the outer wall of the rocker arm 6, and the threaded end of the bolt 15 is tightly pressed against the outer wall of the insertion rod 14. Through the design of the insertion rod 14, the slot 13 and the bolt 15, the maximum limit distance between the two corresponding rockers 6 is further increased, thereby increasing the scope of application to a certain extent.

[0016] Specifically, the driving assembly includes a cylinder 11, which is fixedly installed in the inner cavity of the frame 1 and located between the two slides 8. A connecting plate 12 is fixedly provided at the movable end of the cylinder 11, and the two ends of the connecting plate 12 are respectively fixedly connected to the two slides 8. The cylinder 11 can be used as a power source to provide power for the synchronous movement of the two slides 8.

[0017] Specifically, the limit end of the rocker 6 is set to be spherical, and this design can reduce the friction between the rocker 6 and the metal plate. The rod body 4 and the slot block 5 are connected by a bearing. The design purpose is to reduce the friction when the rod body 4 rotates and reduce the rotation loss of the rod body 4.
