Technical Field

[0001] The utility model belongs to the technical field of gear processing, and particularly relates to a three-in-one hot upsetting machine for a passive gear blank. Background Art

[0002] like Figure 1 , the processing of the passive gear blank requires three steps:

[0003] S1, extruding a heated cylindrical steel column 91 to form a round cake 92;

[0004] S2, extruding the center of the heated round cake 92 to form a cylinder-shaped body 93 with a lower center;

[0005] S3. Punching the central thin area of ​​the heated cylinder-shaped body 93 to cause the central thin area to fall off, thereby forming an annular driven gear blank 94.

[0006] The above three processes are respectively called "flattening processing", "thinning processing" and "forming processing".

[0007] Currently, these three steps require three pieces of equipment, which takes up a large area. Utility Model Content

[0008] The technical problem to be solved by the utility model is: how to reduce the floor space occupied by the equipment.

[0009] The technical solution of the utility model is specifically as follows:

[0010] A three-in-one hot upsetting machine for a passive gear blank comprises a hot upsetting machine, which is provided with two processing areas with transparent front and rear sides, and the processing area is provided with three processing positions: a flattening processing position, a thinning processing position, and a forming processing position; the flattening processing position comprises a flattening lower mold fixed to the bottom surface of the processing area, and a flattening upper mold is provided above the lower flattening mold to cooperate with it; the thinning processing position comprises a thinning lower mold fixed to the bottom surface of the processing area, and a thinning upper mold is provided above the thinning lower mold to cooperate with it; the forming processing position comprises a forming lower mold fixed to the bottom surface of the processing area, and a forming upper mold is provided above the forming lower mold to cooperate with it; the flattening upper mold, the thinning upper mold, and the forming upper mold are all connected to the top surface of the processing area through a hydraulic cylinder.

[0011] The flattening lower mold, the thinning lower mold, and the forming lower mold are evenly distributed on the diagonal line of the processing area.

[0012] Compared with the prior art, the technical effect of the present invention is that the present invention integrates the equipment of three processes into one hot forging machine, thereby reducing the floor space occupied by the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.

[0017] like Figure 2 A three-in-one hot upsetting machine for a passive gear blank includes a hot upsetting machine 10, which is provided with a processing area 11 with two transparent front and rear sides. The processing area 11 is provided with three processing positions: a flattening processing position, a thinning processing position, and a forming processing position.

[0018] The flattening processing station includes a flattening lower mold 21 fixed on the bottom surface of the processing area 11 , and an upper flattening mold 22 cooperating with the lower flattening mold 21 is provided above the lower flattening mold 21 .

[0019] The ironing processing station includes an ironing lower mold 31 fixed to the bottom surface of the processing area 11 , and an ironing upper mold 32 cooperating therewith is provided above the ironing lower mold 31 .

[0020] The forming processing station includes a forming lower mold 41 fixed on the bottom surface of the processing area 11 , and an upper forming mold 42 cooperating with the forming lower mold 41 is provided above the forming lower mold 41 .

[0021] The flattening upper mold 22 , the thinning upper mold 32 , and the forming upper mold 42 are all connected to the top surface of the processing area 11 through a hydraulic cylinder 50 .

[0022] In order to facilitate cooperation with the robot, the flattening lower mold 21, the thinning lower mold 31, and the forming lower mold 41 are evenly distributed on the diagonal line of the processing area 11.

[0023] Its working principle is:

[0024] The steps include:

[0025] S1. The first robot 81 places the heated cylindrical steel column 91 into the flattened lower mold 21 from the upstream link on the rear side. The cylindrical steel column 91 is processed into a round cake 92.

[0026] S2. The first robot 81 transfers the circular cake 92 from the flattening lower mold 21 to the thinning lower mold 31. The circular cake 92 is processed into a cylinder-shaped body 93.

[0027] S3, the second robot 82 transfers the cylinder-shaped body 93 from the ironing lower die 31 to the forming lower die 41, and the cylinder-shaped body 93 is processed into a driven gear blank 94;

[0028] S4. The second robot 82 transfers the driven gear blank 94 from the lower forming die 41 to the front downstream link.

[0029] Features of this application:

[0030] S1. The utility model integrates the equipment of three processes into one hot forging machine, reducing the floor space occupied by the equipment.

[0031] S2. The front and back sides of the processing area are transparent, and two robots can be placed on the front and back sides respectively, which can reduce the interference between the two.

[0032] S3, flattening the lower mold 21, thinning the lower mold 31, and forming the lower mold 41 are evenly distributed on the diagonal of the processing area 11, which can reduce the sum of the manipulator movement paths of the second robot, shorten the transportation time, and maintain the temperature of the workpiece as much as possible, providing convenience for processing.
