Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] Such as Figure 1~5 As shown, the manufacturing method of the T-shaped chute base plate of the present embodiment includes steps:

[0030] S1. Mold making and moulding: use the method of dividing the product, use the metal aluminum mold to make the parts of the plate 1 and the groove 2 according to the shape of the T-shaped chute base plate, and then combine the models. The modules must be dried before assembling the model, then bonded with hot melt adhesiv...

Abstract

The invention relates to the technical field of rail equipment manufacturing and discloses a manufacturing method of a T-type sliding groove base plate. The method includes the steps that S1, a mold is manufactured and assembled; S2, the mold is coated with coating and dried; S3, boxing is performed; S4, pouring is performed; S5, cleaning is performed. The manufacturing method of the T-type sliding groove base plate avoids sand inclusion, air holes, cracks, shrinkage porosities and shrinkage cavities, poor surface quality and other defects.

Description

technical field [0001] The invention relates to the technical field of rail equipment manufacturing, in particular to a method for manufacturing a T-shaped chute base plate. Background technique [0002] Prestressed reinforced concrete (prestressed concrete, PC) track beam special cast steel tensile curve support movable support is a hinge (roller) shaft type, which is the connection and load transmission between the track beam and the cover beam, and can meet the vertical requirements of the beam body. Mechanical devices for support and beam longitudinal displacement requirements. [0003] The PC track beam special cast steel tension support is a component that bears the vertical load at the end of the PC beam. The upper hem, lower hem and T-shaped chute base plate of the entire curved support are steel castings. The upper hem and the lower hem of the movable support are connected through the roller shaft and the pressure bearing plate, which not only meets the vertical tr...
