When the blank of the axle housing is processed, firstly, the first chain conveying device 12 conveys the blank to one end of the blank heating rack 21 on the blank conveying rack 11, then the blank transferring component 13 transfers the conveyed blank to the blank heating rack 21, then the blank conveying component 23 on the blank heating rack 21 slowly moves the blank above the blank into the heating furnace body 22, the blank is heated to a sufficient temperature in the heating furnace body 22 and is sent out, then the heated blank enters the blank positioning component 24 and is adjusted to a proper position and height by the blank conveying component, so that the blank is controlled by the transferring manipulator 32 to take out the blank by the blank clamping component 33 and is safely and accurately transferred into the axle housing punching machine 31 for punching processing, after the processing is finished, the transferring manipulator 34 controls the first finished product clamping component 35 to transfer the punched semi-finished product onto the finished product conveying rack 41 and is conveyed to the side of the stacking manipulator 43 by the second chain conveying device 42, and finally the stacking manipulator 43 controls the second finished product clamping component 44 to sequentially clamp the semi-finished product conveying rack 41 and transport the axle housing on a designated rack for convenient subsequent process.

As shown in fig. 2, the blank transferring assembly 13 includes a transferring frame 131 suspended above between the blank conveying frame 11 and the blank heating frame 21, a moving device 132 movably disposed on the transferring frame 131, a lifting device 133 liftable and disposed on the moving device 132, and a magnetic attraction device 134 fixed at one end of the lifting device 133, wherein the moving device 132 is disposed between the blank conveying frame 11 and the blank heating frame 21, the magnetic attraction device 134 is disposed at one end of the lifting device 133 close to the blank conveying frame 11 or the blank heating frame 21, when the blank is conveyed to one end of the blank conveying frame 11 close to the blank heating frame 21, the moving device 132 above the blank conveying frame 131 moves to a position right above the blank, and the lifting device 133 disposed at one point lowers the magnetic attraction device 134 at one end thereof to approach the blank and is closely attached to the blank, and then the lifting device 133 raises the magnetic attraction device 134 and the blank, and the blank are moved to the blank heating frame 21 together by the movement of the moving device 132, and finally the lifting device 133 lowers the magnetic attraction device 134 and the blank together with the blank, and releases the magnetic attraction device 134 when the blank is moved to a proper height, thereby achieving a quick transferring effect.

As shown in fig. 3, the blank conveying assembly 23 includes a plurality of fixed support beams 231 fixed on the blank heating frame 21 and arranged in parallel, a moving support beam 232 movably and vertically disposed on the blank heating frame 21 and located between gaps of adjacent fixed support beams 231, and a driving device 5 disposed inside the blank heating frame 21 and driving the moving support beam 232 to move and lift, wherein two ends of the fixed support beam 231 are respectively disposed at an inlet and an outlet of the heating furnace body 22, and one end of the moving support beam at the outlet of the heating furnace body 22 is provided with a slope 233, when the blank is transferred onto the blank heating frame 21, the blank is firstly placed on the plurality of fixed support beams 231 on the blank heating frame 21, and then the moving support beam 232 located between adjacent fixed support beams 231 is lifted up from the fixed support beams 231 and moved down to the outlet end of the heating furnace body 22 by a distance under the driving device 5, the blank is re-placed on the fixed support beams 231, thereby achieving the effect of moving on the fixed support beams 231, and the moving back to the blank supporting beams 232 before moving, and the blank is moved back to the heating furnace body 231, and the blank heating frame can be continuously moved to the heating furnace body, thereby achieving the effect of continuously heating the blank and the heating furnace body 22. Wherein the slope 233 at one end of the fixed support beam 231 can help the blank slide out of the heating furnace body 22.

As shown in fig. 3 and 4, the first driving device 5 includes a plurality of pairs of bearing blocks 51 fixed to two sides of the bottom of the blank heating frame 21, a rotating shaft 52 installed in a shaft hole of the bearing blocks 51, a first rotating handle 53 and a second rotating handle 54 fixedly connected to two ends of the rotating shaft 52 and perpendicular to each other, a roller 531 rotatably connected to the first rotating handle 53, a moving frame 56 overlapping and sliding on the roller 531 and located in the blank heating frame 21, a pair of connecting rods 55 hinged to one end of all the second rotating handles 54 on two sides of the blank heating frame 21, a pair of hydraulic telescopic cylinders 58 driving the two connecting rods 55 to move, a first horizontal sliding hole 551 opened on the connecting rod 55 and located between the two adjacent rotating handles 54, a second vertical sliding hole 561 opened on one side of the moving platform and located between the adjacent first rotating handles 53, sliding rods 57 having two ends slidably connected to the first sliding hole 551 and the second sliding hole 561 respectively, a connecting rod 562 fixedly connected to the supporting beam on the moving frame 56, a cylinder body hinged to the heating frame 21, a damping sleeve 59 connected to one end of the telescopic cylinder 59, and a damping sleeve 59 fixed on the moving platform.

When the supporting beam 232 needs to be moved to work, firstly, the hydraulic telescopic cylinder 58 pulls the connecting rod 55, so that the second rotating handle 54 of the hinged connecting rod 55 rotates on the bearing seat 51, the second rotating handle 54 rotates to drive the first rotating handle 53 to rotate through the rotating shaft 52, then the roller 531 rotates along with the first rotating handle 53 to lift the moving frame 56 overlapped and sliding on the roller 531 upwards, the moving frame 56 is connected with the moving supporting beam 232 through the connecting column 562, so that the moving supporting beam 232 can lift the blank upwards along with the moving frame 56, meanwhile, the connecting rod 55 can move towards the lower part of the blank heating rack 21 and towards the outlet of the heating furnace body 22 during the rotation process of the second rotating handle 54, and the sliding rod 57 at the moment can move on the first sliding hole 551 and the second sliding hole 561 due to the movement of the connecting rod 55 and the moving frame 56, and when the moving frame 56 is lifted to a proper height, the sliding rod 57 can just move to one end of the first sliding hole 551, so that when the moving frame 56 is lifted and the moving effect of moving supporting beam 232 and the moving heating furnace body 232 is achieved at the same time.

When the moving support beam 232 moves to a proper distance, the hydraulic telescopic cylinder 58 pushes the connecting rod 55 to enable the moving frame 56 and the moving support beam 232 to descend, at the moment, the connecting rod 55 moves towards the blank heating frame 21 and towards the inlet direction of the heating furnace body 22, because the sliding rod 57 does not slide at the other end of the sliding hole I551 in the front section descending process, the moving support beam 232 firstly puts the blank on the fixed support beam 231 in the period, and in the rear section descending process that the moving support beam 232 is lower than the fixed support beam 231, the connecting rod 55 is dragged back to the initial position through the sliding rod 57, so that the moving beam is prevented from bringing the blank back to the position which is away from the fixed support beam 231 before in the descending process. Wherein the damper 59 can limit the horizontal movement of the moving frame 56 during the independent ascending and descending of the moving frame 56 to avoid pushing the moving frame 56 to move in advance due to the friction between the roller 531 and the moving frame 56 when the first rotating handle 53 starts to rotate.
