Description

Technical Field

[0001] The utility model relates to the technical field of folding a limit plate, in particular to a limit plate folder for an elevator. Background Art

[0002] The elevator stop is controlled by a limiter. When the elevator rises or descends, the limit plate will first touch the first switch. At this time, the proportional valve receives the command and slows down the flow of hydraulic oil to make the elevator descend smoothly. Then the limit plate will touch the second switch and stop at the specified position. This avoids uneven floors due to long use time or temperature changes. During the processing, the limit plate needs to be folded into shape by a limit plate folder.

[0003] The door closing limiter of the elevator car is composed of a hinged annular member, a connecting piece connected to the annular member, and other parts. The annular member and connecting piece of the door closing limiter have specific structural shapes and connecting holes, and need to be punched by punching equipment. When the punching equipment in the prior art punches the annular member and connecting piece of the door closing limiter, the upper mold moves down and punches in correspondence with the lower mold. After the upper mold moves down, the upper mold and the lower mold are positioned in the positioning groove at the top of the lower mold by the positioning column at the bottom of the upper mold. However, during the downward movement of the upper mold, the upper mold is prone to shaking, and when the upper mold and the lower mold are docked, there is a tendency to be misaligned, resulting in a sense of vibration during docking, and even a poor docking, causing impact damage to the mold. In addition, when the annular member and the connecting piece of the door closing limiter are demolded after stamping, an ejection method is adopted, and the structure of the ejection mechanism is relatively complex and the cost is relatively high.

[0004] The existing punching equipment for processing the elevator car door closing limiter with Chinese patent publication number CN218744252U has a positioning column at the bottom of the upper die and a positioning groove at the top of the lower die; the lower die is arranged at the top of the support seat, and a limiting mechanism is arranged on the outer side of the support seat, the limiting mechanism includes a fixed column, a spring and a limiting column, the spring is sleeved on the outside of the fixed column, the limiting column is connected to the top of the spring, and the limiting column is sleeved on the outside of the fixed column; a plurality of balls are embedded in the outer periphery of the limiting column, and the outer side of the balls arranged on the side of the limiting column close to the lower die is in the same plane as the outer side of the upper die and the lower die; an electromagnet is installed inside the punch; and a pushing mechanism is arranged on the outer side of the lower die. The advantages of the utility model are: during the downward movement of the upper die, the limiting mechanism limits the upper die to move downward at a limited position without shaking, and the upper die and the lower die are accurately docked; the demoulding mechanism for demoulding the annular part or the connecting piece of the door closing limiter after stamping is completed is simple in structure, and demoulding is also convenient, which reduces costs.
