Problems solved by technology

However, the production process of this kind of sliding bed has high requirements on the surfacing welding process. The blisters, leaks, and slag inclusions formed in the surfacing process will lead to unqualified quality of the sliding bed and low production efficiency. Moreover, in the surfacing welding process The metal is easily oxidized during the process, which affects the quality and service life of the sliding bed
CN101338425A discloses a laser cladding process of wear-resistant and anti-corrosion alloy coating on the surface of railway turnout sliding bed plate. This process uses laser to clad alloy layer on the surface of sliding bed plate. This process also has expensive production equipment, high production cost and low production efficiency. Low, low yield and other disadvantages

Embodiment Construction

[0029] In the following, the bimetal liquid cladding die forging switch slider bed of the present invention will be further described in detail with reference to the accompanying drawings.

[0030] Such as figure 1 As shown, the bimetal liquid cladding die forging switch slide bed table of the present invention includes a slide bed table body 2 whose bottom is welded to the switch backing plate 1. The upper part of the slide bed table is provided with a wear-resistant sliding table that is slidingly matched with the bottom surface of the dust rail. Plane 3, the sliding bed table body is composed of a low carbon steel welded base 22 and a martensitic stainless steel wear-resistant layer 21 welded to the base by liquid die forging, the low-carbon steel welded base and martensitic stainless steel wear-resistant layer The welding surface 4 is a wavy curved surface, the peak-valley drop is 2-3mm, and the thickness of the martensitic stainless steel wear-resistant layer is 5-15mm. The ...

Abstract

The invention discloses a bimetal liquid fusion covering and die forging turnout sliding table and a manufacturing method of the sliding table. The sliding table comprises a sliding table body, the bottom of the sliding table body is welded to a turnout base plate, the upper portion of the sliding table is provided with an abrasion-resistant plane matched with the bottom of a dust rail in a sliding mode, and the sliding table body comprises a low-carbon-steel welded base and a martensite stainless steel abrasion-resistant layer welded to the welded base in a liquid die forging mode. The contact face of the bimetal liquid fusion covering and die forging turnout sliding table and the dust rail is free of rust, resistant to abrasion, high in hardness and high in shock resistant value. Weldability of the contact portion of the sliding table and the turnout base plate is good. The bimetal liquid fusion covering and die forging turnout sliding table is low in manufacturing cost, long in service life and stable and reliable in work. According to the turnout sliding table produced through the method, metal crystalline grains of the abrasion-resistant layer of the sliding table are fine, the organizational structure is compact, the phenomena of bubbles, loosening and shrinkage do not exist, and the yield of the turnout sliding table produced through the method is high.

Description

Technical field [0001] The invention relates to high-speed railway track technology, in particular to a sliding bed platform for high-speed railway track switches and a manufacturing method thereof. Background technique [0002] The sliding bed platform is an important part of the railway switch. The sliding bed platform is usually fixed on the turnout backing plate by welding. The rail slides on the upper surface of the sliding bed platform when the track is changed. Therefore, the sliding bed platform and the switch backing plate are required The contact part has good weldability, and the contact surface with the tip rail has the characteristics of non-corrosion, wear resistance and high impact resistance. In order to meet the above requirements, the high-speed railway switch in the prior art usually adopts an integral casting process, that is, precision casting of niobium-vanadium-titanium precious metal stainless steel. Although this kind of sliding bed platform can meet the ...
