Abstract
The utility model relates to an improved structure of brake shoe back iron. The improved structure comprises a strip-shaped metal plate, the strip-shaped metal plate is bent in the direction of a circular arc, a door-shaped bending part is arranged in the middle of the strip-shaped metal plate, the door-shaped bending part protrudes to the outside of the circular arc in the radius direction of the circular arc, and more than two protruding sheets are punched on the strip-shaped metal plate from the inner side of the circular arc face inwards. The angle between each protruding sheet and a perpendicular line of a circular arc tangential line passing through the root of each protruding sheet is 5 degrees to 90 degrees. When a brake shoe is manufactured, the strip-shaped metal plate is arranged in a die in a face-up mode, the protruding sheets are upward, combination raw materials for forming gaskets are poured in the die, the protruding sheets are planted in the combination raw materials, and then sintering is carried out. After the sintering is finished, the protruding sheets are embedded in the gaskets, and the strip-shaped metal plate can be combined with the gaskets firmly. The multiple protruding sheets are arranged in the strip-shaped metal plate for forming the back iron in a punching mode, after the gaskets are sintered, the protruding sheets are embedded in the gaskets, the back iron and the gaskets are firmly combined, and the anti-shearing force of the brake shoe is improved.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to the break of vehicle, the particularly brake block in the vehicle brake, and concrete is a kind of improvement structure of brake shoe back iron.
Background technique:
The break of rail traffic vehicles extensively adopts brake shoe as braking member.Consist of behind the liner that brake shoe is comprised of high abrasion resisting material and back iron plate (the being called for short in the industry back iron) sintering.In the prior art, the junction surface of back iron and liner is the skeleton symbol geometric surface, and the performance of anti-shearing force is still waiting to strengthen, otherwise liner might break or break away from back iron.
Summary of the invention:
The purpose of this utility model is to provide a kind of improvement structure of brake shoe back iron, and the performance that the improvement structure of described this brake shoe back iron will solve brake shoe anti-shearing force in the prior art is not enough, liner easily breaks and break away from back iron.
The improvement structure of this brake shoe back iron of the present utility model, comprise a strip metal plate, described strip metal plate is crooked along a circular arc direction, the middle part of strip metal plate is protruded the kink that is provided with a door type or π font along the radial direction of described circular arc to the outside of circular arc, wherein, described strip metal plate has the protrusion tab of two above numbers from the inboard inwardly punching press of its arc surface.
Further, the projected direction of any one described protrusion tab all is arranged in the radially cambered surface of described circular arc.
Further, the angle between the vertical line of the circular arc tangential line of any one described protrusion tab and its root of process is between 5 to 90 degree.
Further, the angle between the vertical line of the circular arc tangential line of any one described protrusion tab and its root of process is between 25 to 45 degree.
Further, the number of described protrusion tab is 8.
Further, the two ends of described strip metal plate are provided with a longitudinal register sheet separately, any one described longitudinal register sheet consists of by planar metal plate, any one longitudinal register sheet all is arranged in the radially cambered surface of described circular arc, and any one longitudinal register sheet all embeds and pass strip metal plate.
Further, the two ends of described strip metal plate are provided with a locating column separately, and any one described locating column protrudes from the outer side surface of strip metal plate.
Further, the middle inside of strip metal plate is provided with two links, and described link is connected to the both sides of opening of the kink of described door type or π font.
Working principle of the present utility model is: when making brake shoe, strip metal plate faced upward put in mould, make protrusion tab upwards, the combination raw materials of formation liner is poured into mould, protrusion tab is implanted in the combination raw materials, then carry out sintering.After sintering was finished, protrusion tab embedded liner, makes strip metal plate and liner strong bonded.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model arranges a plurality of protrusion tabs by process for stamping in the strip metal plate that consists of back iron, behind the liner sintering, protrusion tab embeds liner, makes back iron and liner strong bonded, has improved the anti-shearing force of brake shoe.
