Description

Technical Field

[0001] This utility model relates to the technical field of rail vehicles and key components, and in particular to a slider hot upsetting device. Background Technology

[0002] To ensure that the overall subway vehicle product can meet the diverse product types and ever-increasing production capacity demands of the OEM, traditional casting or machining methods are insufficient to satisfy both performance and cost requirements. Improving product efficiency and quality through process optimization necessitates a specialized machining mold for slider products to meet quality and delivery requirements. However, existing technologies suffer from the following problems: 1. Traditional mold structures are overly complex, hindering worker installation; 2. Products machined using traditional molds are difficult to form or exhibit severe burrs and flash after forming, leading to material waste; 3. Traditional molds have short lifespans, increasing maintenance and repair costs. Therefore, we propose a slider hot upsetting forming device to address these issues. Utility Model Content
