Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of press machine pull rod, specifically relates to a press machine pull rod fastening device. BACKGROUND

[0002] In today's industrial production field, as an important mechanical equipment, the press machine is widely used in metal processing, plastic forming, automobile manufacturing and many other industries. The performance and stability of the press machine have a crucial influence on production efficiency, product quality and production safety.

[0003] The pull rod of the press machine is one of its key components, responsible for transmitting pressure and maintaining structural stability. However, in practical applications, ensuring the secure fixation of the pull rod has always been a challenging problem.

[0004] Firstly, in the design of the fastening structure, many devices use a single-point or a small number of fixed-point method. This design, due to uneven stress distribution when the press machine is working, is prone to cause the pull rod to bear excessive stress at the single-point fixed position, thereby increasing the risk of deformation and damage of the pull rod, and further affecting the overall precision and stability of the press machine.

[0005] Secondly, in terms of operation process, many existing fastening devices are complex and cumbersome to operate. They may require independent operation on multiple fixed points in sequence, not only consuming a lot of time and effort, but also due to the difficulty of completely consistent operation sequence and force of each fixed point, it is easy to appear the situation of uneven fastening degree. This not only reduces the work efficiency, but also may cause safety hazards due to improper fastening.

[0006] Furthermore, in terms of adaptability, some existing fastening devices can only be applied to pull rods of specific sizes and specifications. When different sizes of pull rods need to be replaced, the fastening device often needs to be adjusted significantly or even replaced entirely, which undoubtedly increases the production cost and difficulty of equipment maintenance.

[0007] In addition, some existing fastening devices are prone to failure during long-term use due to component wear, corrosion and other reasons, but their maintenance and repair are very complex and require professional technical personnel, increasing the maintenance cost and downtime of the enterprise.
