The utility model solves the problems of the technologies described above adopted technical scheme: a kind of powder heating powder-feeding shoe, comprise powder-feeding shoe main body, it is characterized in that: in the powder storing chamber of described powder-feeding shoe main body, erection has the middle frame for heating powder, middle frame is made up of upper and lower two-layer heating medium for heating pipe, and the rear end of powder-feeding shoe main body is provided with the interface that heating medium for heating pipe is connected with additional heating agent.
As improvement, the frame structure that described powder-feeding shoe main body is is material with aluminium alloy or copper alloy, is provided with powder input port at the top of powder-feeding shoe main body, and powder input port is provided with the cover plate that can open with closed.
As improvement, described cover plate is arranged on powder input port place by hinged mode.
As improvement, described heating medium for heating Guan Weiyi root, heating medium for heating pipe is the hollow tube adopting aluminium alloy or copper alloy material to make, heating medium for heating pipe is that many U-shapeds are laterally laid in the middle part of the powder storing chamber of powder-feeding shoe main body, and the left and right inwall of powder storing chamber laterally offers the detent for the erection of heating agent heating tube.
Improve, the left and right sides symmetry of described powder-feeding shoe main body has the locating hole for assembling pin or axle again.
Improve, the rear end of described powder-feeding shoe main body has two through holes for mounting interface, and the inner end of interface is connected with the open end of heating medium for heating pipe, and outer end is connected with the carrier pipe of additional heating agent again.
Compared with prior art, the utility model has the advantage of: the heating medium for heating pipe being used for heating powder is set in powder-feeding shoe, flow through heating medium for heating pipe by heating agent to heat the powder before the compacting that is shaped, make the temperature that powder preheating reaches suitable, effectively solve the low problem of green compact pressed density.The utility model structure is simple, cost is low, by preheating the suppression performance improving powder to powder before the compacting that is shaped, reducing forming pressure, thus reaching the effect improving shaping green density.
