In the above technical solution, a more specific technical solution may also be: the upper portion of locating piece is equipped with the profile modeling concave surface similar with thermal shield shape down, and thermal shield can block the house down in the profile modeling concave surface of locating piece, the lower part of going up the locating piece is equipped with the profile modeling concave surface similar with last thermal shield shape, goes up thermal shield and can block the house in the profile modeling concave surface of going up the locating piece prevents its deformation when guaranteeing thermal shield and last thermal shield to compress tightly the laminating on the blast pipe down.
Further: the positioning device is characterized in that a plurality of positioning pins are arranged in the profiling concave surface of the upper positioning block, positioning holes matched with the plurality of positioning pins are formed in the upper heat shield, and the upper heat shield can be accurately positioned when placed on the profiling concave surface of the upper positioning block.
And further: still be equipped with polylith magnet in the profile modeling concave surface of last locating piece, go up the heat shield and have magnetism, guarantee to go up the heat shield along with go up the locating piece can not drop at the in-process of upset.
Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has: through the one end of the fixed blast pipe of stationary cylinder, rethread die clamping cylinder will be gone up and to separate heat exchanger and separate the tight laminating of heat exchanger clamp down and can begin weldment work at the other end of blast pipe, need not the bare-handed process of pressing on the heat exchanger that separates of staff, has improved production efficiency and welding quality.
