Description

Fixed frock of preparation impeller wax matrix

Technical Field

The utility model belongs to the technical field of the precision casting impeller, a fixed frock of preparation impeller wax matrix specifically says so.

Background

The impeller machine is a power machine which takes continuous rotating blades as a body and enables energy to be converted between fluid working media and shaft power. It can be divided into axial flow, radial flow, mixed flow, combined type, etc. according to the moving direction of the fluid. Generally, axial flow has high efficiency and large flow rate, but the pressure ratio (expansion ratio) is low; the radial flow efficiency, flow rate is slightly low, but the pressure ratio (expansion ratio) is large. The power generation system can be classified into a prime mover such as a steam turbine, a gas turbine, etc. (output power) according to functions; working machines, such as water pumps, fans, compressors, propellers, etc. (power consumption). Common working media comprise air, water, hydrogen, ammonia, carbon dioxide and the like, and the characteristics of the turbines with different working media are different.

The device belongs to two secondary disciplines of power machinery and fluid machinery under the disciplines of power engineering and engineering thermophysics, and has wide application, including a gas compressor, a turbine, a rotor wing and the like in military aircrafts and ship engines; a marine propeller thruster; a water pump, a fan, a steam turbine, a wind turbine and a water turbine in the power generation system; the turbines used in the refrigeration industry are compressors and expanders; compressors, fans, etc. in the chemical industry, turbomachinery are often one of the most critical, most important components in these industries.

Impeller machines hold a very important position in national economy, especially in the whole heavy industrial system. Among them, the gas turbine has been widely used as the core power in high-end fields such as aviation, power station, ship, missile, tank, heavy-duty locomotive, etc., and the main or auxiliary power in general industrial fields such as metallurgy, exploration, chemical industry, civil engineering, etc., so that more and more people think that the production level of the gas turbine has become one of the most important marks for measuring the whole strength of a national industry. The turbine can realize higher single machine power (up to million kW level), higher rotating speed, reliable operation, low fuel (multipurpose coal) cost and relatively mature technology, so the turbine has irreplaceable effect on the aspect of being used as the main power of a central power station, a large ship and a warship. The higher reliability also makes the application of the steam turbine more common than the combustion engine in the industries of metallurgy, chemical engineering and the like.

The impeller machine is the largest sending equipment in the energy field at present (a thermal power plant, a gas turbine power plant, a hydropower station, a nuclear power station and the like are all used), and the research on improving the efficiency of the impeller machine is one of important methods for solving the energy problem. The production difficulty of complex impeller products in precision casting is high, and in order to produce the castings by an investment casting method, a high-precision, complex and integral wax pattern is obtained firstly. The traditional combined wax pattern is formed by melting and butting the joint parts of the wax patterns together by means of a heated soldering lug, the operation is only manual combination, the shape and the size of the wax pattern combination are greatly changed, the precision is low, and the accuracy of the wax pattern combination is greatly different due to human factors.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that manual operation is adopted in the combination of impeller wax matrix among the prior art, and its size and precision can't effectively be guaranteed, this application provides a fixed frock of preparation impeller wax matrix, has promoted the quality of impeller combination product.

In order to achieve the purpose, the technical scheme of the application is as follows: the utility model provides a fixed frock of preparation impeller wax matrix, includes: base, rotation axis, lower lock template, guide bracket, lock template, locking screw, be equipped with the rotation axis on the base, the rotation axis top is connected with the centre bore cooperation of lower lock template, and the both sides of locking the template under are equipped with guide bracket, are equipped with the poroid slide on every guide bracket, lock the template and be located lock template top down, be equipped with branch in last lock template both sides, branch is located the poroid slide that corresponds, is equipped with locking screw at the outer tip of branch.

Furthermore, the bottom of the rotating shaft is rotatably connected with a central hole of the base.

Further, the base is fixed on the workbench.

Further, the lower cover plate of the impeller wax mould is positioned on the lower lock-type plate, and the upper cover plate of the impeller wax mould is contacted with the bottom surface of the upper lock-type plate.
