Positioning die structure for tank body of mixer truck
Technical Field
The invention relates to the technical field of stirring tank production, in particular to a positioning die structure of a stirring tank body.
Background
A mixer truck, which is a special truck for transporting concrete for construction; due to its shape, it is also commonly referred to as a river snail vehicle, olive vehicle. These trucks are equipped with cylindrical mixing drums to carry the mixed concrete. The mixing drum can be always kept to rotate in the transportation process so as to ensure that the carried concrete can not be solidified. After the concrete is conveyed, water is usually used for flushing the interior of the mixing drum, so that the occupied space of the hardened residual concrete is prevented, and the volume of the mixing drum is reduced.
The concrete mixing and transporting truck consists of a vehicle chassis and a special device for concrete mixing and transporting. The special mechanism mainly comprises a power takeoff, a front support and a rear support of a mixing drum, a speed reducer, a hydraulic system, the mixing drum, an operating mechanism, a cleaning system and the like. The operating principle is that the power of the automobile chassis is taken out through the power take-off device, the variable pump of the hydraulic system is driven, mechanical energy is converted into hydraulic energy to be transmitted to the variable motor, the motor drives the speed reducer again, and the speed reducer drives the stirring device to stir concrete.
The tank body of the concrete mixing truck generally comprises a front cone, a middle section and a rear cone, and stirring blades are arranged in the tank body. The tank body is usually manufactured in sections, then the stirring blades in each section are welded, and then the tank body is assembled into an integral structure. Because the stirring blade usually needs to be supported by a die in the welding process, the stirring blade is placed at a corresponding position and then welded. Because the jar body is various, and each kind jar body all is different for each kind jar body all needs the different mould of adaptation when carrying out blade welding, so need often make new mould according to the shape and the size of jar body, cause the waste of time and resource.
