Tool for forming railway track plastic vibration isolator

Abstract

The invention provides a tool for forming a railway track plastic vibration isolator. The tool comprises a rack (1), a pressing assembly (2) and a bearing plate (3), wherein the pressing assembly (2) is mounted on the rack (1) and comprises a telescopic cylinder (2-1), a mounting plate (2-2) and a pressing plate (2-3), the two ends of the telescopic cylinder (2-1) are connected with the mounting plate (2-2) and the rack (1) respectively, and the mounting plate (2-2) is connected with the pressing plate (2-3), so that the pressing plate (2-3) is driven by the telescopic cylinder (2-1) to move up and down in a reciprocating mode; and the bearing plate (3) is mounted on the rack (1), arranged under the pressing assembly (2) and used for placing the railway track plastic vibration isolator (6). Through cooperation of the pressing assembly and the bearing plate, the railway track plastic vibration isolator is stressed in a reciprocating mode, and therefore, the forming result of the railway track plastic vibration isolator is guaranteed.

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
