The utility model discloses a kind of forging dies for automobile rotating shaft, including lower mould body, air blower body and screw rod, the lower mould body die holder one side is provided with connecting plate, linear module is fixedly arranged on the connecting plate, the movable section of linear module is fixedly provided with moving block, the moving block top one side is provided with pipeline, the pipeline intake end is connected between air blower body by connecting pipe, multiple jet structures are provided on the pipeline;The one end of screw rod is fixedly connected with the one end of pipeline, the screw rod is arranged in the hole in the top of moving block, the both ends of screw rod are respectively screw-mounted nut A and nut B, nut A and nut B are respectively with the both sides of moving block top abutment cooperation.The utility model has the length according to the forging surface of forging die, selects suitable pipeline, replaces pipeline by the detachable structure of screw rod and moving block top corresponding, so that the advantage that multiple jet structures blow gas range covers the forging surface of forging die.

The utility model discloses a spray gun relates to iron and steel smelting technical field, including support frame, the inboard sliding connection of support frame has adjusting mechanism, the inboard rotation of adjusting mechanism is connected with spray gun body, the upper side of support frame is close to the position rotation of left side and is connected with second telescopic link, the right side rotation of second telescopic link is connected in the upper end of spray gun body, the downside fixed connection of support frame has vibration mechanism, the adjusting mechanism includes sliding frame, the inboard sliding of sliding frame is connected inboard of support frame, the outside rotation of spray gun body is connected in the inboard of sliding frame. The utility model discloses a novel spray gun, through first telescopic link drive sliding frame moves, and then adjusts the distance of spray gun body's lower extreme and the rear side of the inner wall of molten iron jar after the spray pipe, and the setting of the spray pipe and motor is relied on, expands the jet range, has improved the agglomerate efficiency.

The utility model provides a chamber air injection assembly and chemical vapor deposition equipment. The chamber air injection assembly comprises a cover body, a central air injection component and a side air injection component. The cover body comprises a top wall and a side wall. Each side air injection component comprises an edge air injection piece and a middle air injection piece. The edge air injection piece extends from the side wall to the center of the cover body by a first length in the radial direction of the side wall. The edge air injection piece is provided with an edge air outlet. The middle air injection piece extends by a second length from the side wall to the center of the cover body in the radial direction of the side wall. The second length is greater than the first length. The middle air injection piece is provided with a middle air outlet. The middle air outlets are located between the center air injection component and the edge air injection pieces in the radial direction of the side wall. The middle air injection piece comprises a main pipeline and a branch pipeline. The main pipeline is connected to the side wall and extends in the radial direction of the side wall. The branch pipelines are communicated with the main pipeline and intersect with the main pipeline. According to the utility model, the distribution uniformity of the gas in the central area, the middle area and the edge area of the wafer can be improved.
