Tooling for forming plastic vibration isolation pads for railway tracks

Abstract

The invention provides a tooling for forming plastic vibration isolation pads for railway tracks, which includes a frame (1), a pressing assembly (2) and a pressure bearing plate (3); the pressing assembly (2) is installed on the frame (1) ), and it includes a telescopic cylinder (2-1), a mounting plate (2-2) and a pressing plate (2-3), and the two ends of the telescopic cylinder (2-1) are respectively connected to the mounting plate (2-2 ) and the frame (1), and the mounting plate (2-2) is connected with the pressing plate (2-3) to control the pressing plate (2-3) through the drive of the telescopic cylinder (2-1). The lower reciprocating movement; the pressure bearing plate (3) is installed on the frame (1), and is arranged directly below the pressing component (2), and is used for placing the plastic vibration isolation pad (6) of the railway track. In the present invention, through the cooperation of the pressing component and the pressure bearing plate, the plastic vibration isolation pad of the railway track is subjected to reciprocating pressure, thereby ensuring the molding result of the plastic vibration isolation pad of the railway track.

Description

technical field [0001] The invention relates to the technical field of forming railway track plastic vibration isolation pads, in particular to a tool for forming railway track plastic vibration isolation pads. Background technique [0002] In the railway, in order to make the plastic pad adapt to the vertical load of the train and the reciprocating fatigue load during operation, it is often necessary to press the plastic pad in the center of the two concrete slabs and load it with heavy objects to simulate the load of the train, and then The longitudinal reciprocating load is applied to the concrete slab above by two jacks at the front and rear, so as to simulate the load exerted on the plastic pad after the train has passed many times. After the above reciprocating action, the performance of the plastic vibration isolating pad can approach the use standard of the railway industry. At the same time, the load of the forming device will not only shape the plastic vibration is...

Problems solved by technology

[0003] However, due to the unevenness of the concrete slab of the existing forming device, it is difficult to compact the plastic pad uniformly, resulting in that the actual force of the plastic pad after the reciprocating load does not conform to the force of the train running, and there are large The pressure is concentrated. When lifting the concrete slab and heavy objects above, it is time-consuming and labor-intensive, and the efficiency is low. The traditional method uses simple materials for molding. Although the cost is low, the precision is also low. It is difficult to achieve the ideal shape every time. Forming effect
