Description

Technical Field

[0001] The utility model relates to the technical field of elevator parts production, in particular to a hole punching tool for forming and processing bolt connection holes of a counterweight bracket. Background Art

[0002] The counterweight bracket plays an important role in the elevator. It is a key component in the elevator system, mainly carrying the weight of the counterweight and ensuring the stable operation of the counterweight in the elevator shaft. The design, manufacturing and installation quality of the counterweight bracket directly affect the safety and stability of the elevator operation. First of all, the counterweight bracket is used to support the counterweight, which is an important part of the elevator, used to balance the weight of the car and reduce the energy consumption of the elevator during operation. With the existence of the counterweight, the elevator can be more stable when running up and down, reducing vibration and noise. Secondly, the design of the counterweight bracket takes into account a variety of factors, including load-bearing capacity, stability, safety, etc. It must be able to bear the weight of the counterweight and remain stable during the operation of the elevator without shaking or deformation. At the same time, the installation position of the counterweight bracket also needs to be accurately calculated to ensure the balance and stability of the elevator operation. In addition, the quality and safety of the counterweight bracket are crucial to the operation of the elevator. If there are quality problems or improper installation of the counterweight bracket, it may cause unstable operation of the elevator or even a safety accident. Therefore, in the design and manufacturing process of the elevator, the selection and installation of the counterweight bracket need to be strictly tested and inspected to ensure its quality and safety.

[0003] At present, most of the groove-shaped counterweight brackets are assembled and processed by welding technology. In order to reduce the irreversible damage caused by welding size errors, reduce process costs, and reduce the difficulty of production and transportation, the inventor improved the original welding process into a bolt connection process.
