Abstract

The utility model provides a drum raceway of a concrete mixer truck, which is an annular component. An upper rim face and a lower rim face of the raceway are respectively provided with rim surface grooves by ring rolling, and the rim height at the inner ring face part of the raceway is greater than that at the outer ring face part of the raceway. The drum raceway of the concrete mixer truck provided by the utility model has the beneficial effects that firstly, the overall weight of the raceway is reduced by 25%-28% compared with that of the existing solid raceway, so that the consumption of materials is less, and steel is saved; secondly, the inner ring surfaces of the raceway and a mixing drum are wide, so that the contact area between the raceway and a drum body is large, and the stability is good; and thirdly, four-face forging is adopted in a machining process, so that the internal structure of the raceway is fine, and the strength of the raceway is high.

Description

Roller way of barrel body of concrete mixer truck
Technical field
The novel mixing drum supporting member that relates to concrete mixer truck of this use, specifically a kind of roller way of barrel body of concrete mixer truck.
Background technology
Concrete mixer truck is also referred to as concrete mixer, mainly comprises automobile chassis, fluid power system, water system, frame, mixing drum, control system, feed system and discharge system.Raceway on the mixing drum is vital part, owing to being welded on the mixing drum, in case quality problems occur, is not easy maintenance or replacing.The rectangular trapezium structure in existing raceway cross section, its inner ring surface is welded on the mixing drum.The raceway of this shape and structure exists a lot of drawbacks and shortcoming, the one, the contact area of its inner ring surface and mixing drum cylindrical shell is less with respect to the outer shroud area ratio of outer ring surface, supporting surface to cylindrical shell is less, causes mixing drum unstability fully loaded or that carry when heavier to increase; The 2nd, raceway is solid construction, and not only weight is larger, also can use more steel in the manufacturing process, and stock utilization is low.
The utility model content
The purpose of this utility model just provides a kind of roller way of barrel body of concrete mixer truck, stable low, weight is large and consumptive material the is many problem that exist with the raceway that solves existing ladder structure of right angle.
The purpose of this utility model is achieved in that
A kind of roller way of barrel body of concrete mixer truck, it is annular construction member, and ring rolling has rim face groove respectively on the rim face of the both sides of described raceway, and the tall and big rim in the outer ring surface place of the rim at the inner ring surface place of described raceway is high.
On this basis, the utility model also can be shaped with outer annular recess at the inner ring surface of described raceway.
Roller way of barrel body of concrete mixer truck provided by the utility model has following beneficial effect, one, and the more existing solid raceway of raceway overall weight has reduced 25-28%, and consumptive material is few, saves steel; Its two, raceway and mixing drum inner ring surface are wide, increase with the cylindrical shell contact area, stability improves; Its three, process adopts the four sides forging and pressing, the raceway interior tissue is fine and closely woven, intensity is high.
Description of drawings
Fig. 1 is the structural representation of concave-concave grooved roller way of barrel body of concrete mixer truck.
Fig. 2 is concave-concave grooved roller way of barrel body of concrete mixer truck schematic cross-sectional view.
Fig. 3 is the structural representation of three fluted body roller way of barrel body of concrete mixer trucks.
Fig. 4 is three fluted body roller way of barrel body of concrete mixer truck schematic cross-sectional view.
Among the figure: 1, outer ring surface, 2, inner ring surface, 3, rim face groove, 4, outer annular recess.
The specific embodiment
Embodiment 1: concave-concave grooved roller way of barrel body of concrete mixer truck.
As shown in Figure 1 and Figure 2, roller way of barrel body of concrete mixer truck provided by the utility model comprises outer ring surface 1, inner ring surface 2, and two side ring rollings between outer ring surface 1 and inner ring surface 2 have rim face groove 3.
During manufacturing, the annular steel billet employing bimodulus of cast molding is taken turns the ring rolling method forge and press.The bimodulus wheel comprises main wheel group and accessory whorl group, in the time of the reaming of main wheel group, and the rim high (being thickness) of accessory whorl group control ring, and the rim face in both sides suppresses rim face groove 3.
2: three fluted body roller way of barrel body of concrete mixer trucks of embodiment.
As shown in Figure 3, Figure 4, roller way of barrel body of concrete mixer truck provided by the utility model comprises outer ring surface 1, inner ring surface 2, and two side ring rollings between outer ring surface 1 and inner ring surface 2 have rim face groove 3, and ring rolling has outer annular recess on inner ring surface 2.
During manufacturing, take bimodulus wheel ring rolling method to forge and press to the annular steel billet of cast molding.The bimodulus wheel comprises main wheel group and accessory whorl group, extrudes outer annular recess 4 at inner ring surface in the time of the reaming of main wheel group, the rim high (being thickness) of accessory whorl group control ring, and the rim face in both sides suppresses rim face groove 3.

Claims (2)

1. roller way of barrel body of concrete mixer truck, it is annular construction member, it is characterized in that, and ring rolling has rim face groove respectively on the rim face of the both sides of described raceway, and the tall and big rim in the outer ring surface place of the rim at the inner ring surface place of described raceway is high.
2. roller way of barrel body of concrete mixer truck according to claim 1 is characterized in that, is shaped with outer annular recess at the inner ring surface of described raceway.
