Embodiment Construction

[0032] Embodiments of the present invention will be described below with reference to the drawings.

[0033] see Figure 1 to Figure 2 , the present invention provides a railway fastener clip forming mold, which is suitable for processing and forming a specific ω-shaped clip, and the railway fastener clip (such as Figure 7 shown) is obtained by inserting the elongated spring bar blank 9 (such as Figure 6 Shown) After heating, it is sent into this mold for pressing, and it is pressed into finished products through space fluctuations (such as Figure 8 , Figure 9 shown).

[0034] Specific as figure 1 and figure 2 In the first embodiment shown, the forming mold mainly includes a base 1 , a bracket 3 and an upper template 7 . The base 1 is fixed with a lower roller frame 11, which is provided with an ω-shaped groove 11-1, and the upper template 7 is provided with an upper roller frame 6 that cooperates with the lower roller frame 11, and the upper roller frame 6 The pos...

Abstract

The invention discloses a railway fastener elastic strip forming die and a forming method. The forming die comprises a base, racks and an upper template, wherein the base is fixedly provided with a lower roller carrier with an omega-shaped groove, the upper template is provided with an upper roller carrier which is provided with a press head adaptive to the omega-shaped groove of the lower roller carrier, the lower roller carrier is also symmetrically connected with two bent oscillating bars, one end of each bent oscillating bar is pivoted with the lower roller carrier, the racks are arranged at two sides of the lower roller carrier, and the racks are hinged with a lever which is used for bending two ends of the elastic strip. The railway fastener elastic strip forming die has the main beneficial effects that the appearance of the elastic strip is manufactured by adopting a two-step molding manner, so that the defects of the three-step molding manner are improved to some extent, and compared with the one-step molding elastic trip machine, the railway fastener elastic strip forming die has the advantages that the molded module has a simple structure, and low cost.

Description

technical field [0001] The invention relates to a forming mold and a forming method for elastic strips of railway fasteners, which belong to the field of mechanical processing. Background technique [0002] With the development of my country's railways and the continuous expansion of the country's investment in high-speed railways, the demand for railway fastener systems is increasing, and the quality requirements are also increasing. The fastener is an important component of the track, and the rail and the sleeper are connected together through the fastener. The main function of the fastener is to fix the correct position of the rail, prevent the longitudinal and lateral displacement of the rail, and prevent the rail from tipping over. It can be seen that although the fastener is small, its performance is directly related to the safety of the entire railway transportation system. The spring bar is one of the most important accessories in the fastener system. It mainly use...
