Description

Technical Field

[0001] The utility model belongs to the technical field of elevator stiffener processing, and specifically relates to an elevator stiffener processing device. Background Technique

[0002] An elevator stiffener refers to a metal structure installed on the wall of an elevator shaft, which is used to enhance the structural strength and stability of the elevator shaft. The stiffener is usually made of steel plates, and its shape and size are designed according to the specific conditions of the elevator shaft. The installation of the stiffener can effectively improve the load-bearing capacity and anti-deformation ability of the elevator shaft, thus ensuring the safe operation of the elevator.

[0003] After the elevator stiffener is bent, it needs to be shaped by a processing device to ensure the production quality of the elevator stiffener. In the prior art, Chinese Patent CN213671224U discloses an elevator stiffener processing device, which includes a coil feeding device, a forming machine and a discharging device. The discharging device includes a folding frame, and the folding frame includes an upper bottom plate and a lower bottom plate. An upper template that can slide up and down is installed at the bottom of the upper bottom plate. A rotatable lower template is installed on the upper surface of the lower bottom plate through a vertical rod. A concave groove is formed on the upper surface of the lower template, and a convex groove is formed on the lower surface of the upper template. The concave groove is adapted to the convex groove; a discharging conveyor belt is arranged at the bottom of the lower template, and a chute is formed inside the lower template. The chute is communicated with the concave groove, and a magnetic block is slidably installed in the chute. The utility model can perform shaping work on the plate after bending, so that the plate has higher flatness and straightness.

The top section of the transmission roller 14 is flush with the top surface of the bearing plate 4. The stiffener to be shaped is placed on the two support platforms 5, such that the groove part of the stiffener is located between the two support platforms 5, and the notch of the stiffener faces upward. The loading groove 13 and the transmission roller 14 facilitate the pushing of the stiffener onto the support platforms 5, making the feeding of the device labor-saving.

[0029] In this embodiment, limiting frames 9 are fixedly connected to both ends of the base 1. A notch is formed in the limiting frame 9, and a lifting rod 10 is fixedly connected to the top of the notch. The tops of the two lifting rods 10 are fixedly connected to the same pressing frame 6. The side walls at both ends of the pressing frame 6 are in contact with the side walls of the notch of the limiting frame 9. By using the lifting rod 10, the pressing frame 6 is lowered, driving the pressing block 8 to descend. Through the extrusion of the pressing block 8 and in cooperation with the use of the bearing plate 4 and the support platform 5, the reinforcing rib can be shaped. The setting of the limiting frame 9 can ensure the stability of the descent of the pressing frame 6, prevent the pressing frame 6 from shifting when moving downward, and ensure the quality of shaping. A threaded rod 7 is threadedly connected to the center of the top of the pressing frame 6, and the threaded rod 7 penetrates through the top of the pressing frame 6. The bottom end of the threaded rod 7 is rotatably connected to a pressing block 8. The vertical center line of the pressing block 8 coincides with the vertical center line of the bearing plate 4, and the central axis of the threaded rod 7 coincides with the vertical center line of the pressing block 8.
