specific Embodiment

[0057] In describing the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", " Back", "Left", "Right", "Vertical", "Horizontal", "Top", "Bottom", "Inner", "Outer", "Clockwise", "Counterclockwise", "Axial", The orientation or positional relationship indicated by "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying the referred device or element Must be in a particular orientation, be constructed in a particular orientation, and operate in a particular orientation, and therefore should not be construed as limiting the invention.

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in d...

specific Embodiment 1

[0061] An automatic multi-station forging production line for a sector gear shaft, the starting end is provided with a feeder 1, the feeder 1 is provided with a material basket 102, and a push plate 101 is provided inside the material basket 102, the thickness of the push plate 101 is the same as that of the billet bar The diameter is the same, and there are three push plates 101, which are respectively low push plate, middle push plate and high push plate. If the push plate is high, the axial direction of the billet rod is not the same as the thickness direction of the push plate 101 during this process, and it cannot stay on the push plate, and falls back to the material basket 101 under the action of its own gravity for the next push cycle, which can Staying on the push plate 101 and being pushed to the high push plate includes two situations: lying horizontally and standing upright, and the high push plate pushes the blank bars of these two postures into the first plate cha...

specific Embodiment 2

[0078] On the basis of Embodiment 1, an automatic rotating device is installed in the heating furnace, and the billet is held by the automatic rotating device to rotate 90-180° clockwise or counterclockwise and move along the feeding direction of the conveying line.

[0079] Specifically, plate chains are used for conveying in the heating furnace, each plate chain is provided with a V-shaped supporting plate, and the bottom of the V-shaped supporting plate is provided with rollers, and the top of the rollers is exposed above the bottom of the V-shaped supporting plate, and is in contact with the billet bar. At the joint, the rollers form an angle of 45 degrees with the conveying direction of the plate chain. During the forward conveying process of the plate chain, the rollers are driven to rotate on the bottom pallet, and the rollers drive the billet rods to rotate in the V-shaped pallet.

Abstract

The invention discloses an automatic multi-station forging production line for sector gear shafts, which comprises a feeding machine, a heating furnace, a dephosphorization device, a forging press and a cooling conveyor which are connected in sequence according to a processing flow, after the feeding machine sorts blank bars, the blank bars are conveyed to a first plate chain conveyor connected behind the feeding machine, and the first plate chain conveyor is connected with a second plate chain conveyor; a derusting and deburring device and a saponification device are sequentially arranged on the plate chain conveyor; the heating furnace and the forging press are connected through a second plate chain conveyor, the dephosphorization device is fixed to the second plate chain conveyor, and the dephosphorization device is provided with a steel wire wheel brush channel and a water mist channel; the forging press and the second plate chain conveyor carry materials through a six-axis mechanical arm, and a double-station forging and pressing die is fixed in the forging press and comprises a forming station and an edge cutting station. The sector gear shaft forging system has the beneficial effects that automation of sector gear shaft forging is achieved, logistics delivery is completed through the mechanical arm or the conveyor, full-station and full-process automation is achieved, and the dephosphorization, the double-station forging and pressing die and the controllable isothermal slow-cooling cooling conveyor guarantee the forging and pressing quality of forged parts.

Description

technical field [0001] The invention belongs to the field of gear shaft blank manufacturing, in particular to an automatic multi-station forging production line for sector gear shafts. Background technique [0002] The sector gear shaft is a mechanical part that supports the rotating parts and rotates with them to transmit motion, torque or bending moment. The sector gear shaft in this case is a transmission part in the steering system of an automobile, requiring high strength and large load-bearing torque. [0003] The shape and deformation of the forged material show complex and uneven distribution characteristics during the forging process, and the internal structure of the material is also changing complexly during the forging process. These reasons will have an important impact on the mechanical properties of the post-forging. Due to the uneven distribution of material structure, forgings often have performance defects in actual production. Therefore, controlling the in...
