Description

Technical Field

[0001] This utility model relates to railway track processing technology, and in particular to a grooved wear-resistant guard rail twisting machine for railway turnouts. Background Technology

[0002] Channel-type wear-resistant guard rails are components welded together from channel-type steel guard rails and wear-resistant alloy steel bars. They are essential accessories for railway turnouts (such as...). Figure 1 (As shown). This product is used in railway turnouts to control the direction of train wheel movement, ensuring the wheel passes normally through harmful spaces without misaligning with the flange groove, and protecting the frog tip from wheel impact damage. It is an essential turnout accessory.

[0003] Wear-resistant guardrails are made by splicing and submerged arc welding channel steel guardrails with wear-resistant alloy steel strips. Due to the high-temperature welding process, the welding rod filling the bevel weld fused with the channel steel and alloy steel strips, resulting in extremely high shrinkage stress after rapid cooling. Furthermore, the wear-resistant alloy steel strip is only embedded in one corner of the entire channel steel guardrail and has two long welds (see...). Figure 1 In addition, the channel steel guardrail itself may have a twisted mounting base surface before processing (see...). Figure 2 This process exacerbates the shrinkage, deformation, and twisting of the product. Therefore, it is essential to use straightening and correction equipment to process the welded semi-finished products, ensuring that the straightness and flatness of the products meet technical requirements.

[0004] Currently, straightening machines used for correcting grooved wear-resistant guardrails typically employ partial hydraulic bending operations. This process struggles to address the problem of twisted mounting surfaces, making it impossible to correct severely twisted grooved wear-resistant guardrails while maintaining the reference axis. Forcing a correction operation will cause internal stress concentration in a specific area, resulting in product damage. Furthermore, if subjected to heavy loads during use, this can lead to guardrail breakage and traffic accidents.

[0005] The deformation of profiles and guard rails after submerged arc welding can cause twisting and contortions, severely affecting product quality. Existing conventional top-bending straightening machines are unable to completely correct this. Therefore, to improve the process and meet technical quality requirements, it is necessary to propose a new solution to address these issues. Utility Model Content
