[0007] Articulated robot for transferring workpieces from the placement rack to the hot forging machine and out.

[0008] Optionally, the truss-type robot comprises a single-arm truss extending from a conveyor to a hot forging machine, and at least two three-axis truss robots moving along the single-arm truss.

[0009] Optionally, the three-axis truss manipulator includes a three-axis driving member, a rotating mechanism and a clamp arranged on the three-axis driving member, and the rotating mechanism drives the clamp to deflect in a vertical plane.

[0011] Optionally, the clamp is an electric clamp.

[0012] Optionally, a pushing member and a material box are respectively provided on both sides of the conveyor 1, and the pushing member is used to push the workpiece to the material box.

[0013] Optionally, the placement rack includes a vertical frame and a grooved plate transversely arranged on the top of the vertical frame, and notches are provided on both sides of the grooved plate to facilitate the articulated robot to grasp the workpiece.

[0014] Optionally, the grooved plate is a V-shaped plate or a U-shaped plate.

[0015] Optionally, multiple medium frequency furnaces are distributed along a straight line.

[0016] Optionally, the screw sleeve hot forging production line further includes a second conveyor, a second truss-type manipulator and a material rack arranged on one side of the hot forging furnace, which are used to transfer and store the materials after the hot end.

[0017] The beneficial effect of the utility model is that the workpiece coming out of the sawing machine falls directly onto the conveyor to the designated position, and then the truss-type manipulator transfers the workpiece directly to the corresponding position of the medium frequency furnace, and after heating and softening, it is transferred to the placement rack by the truss-type manipulator to facilitate the articulated robot to grab it, and then placed on the hot forging machine for forging. After forging is completed, the workpiece is transferred out and placed at the designated position. Therefore, in the entire processing process, each process is carried out continuously, and the material racks between the sawing machine and the medium frequency furnace, and between the medium frequency furnace and the hot forging machine are omitted, thereby reducing the time occupied by the transfer link and improving production efficiency.

DETAILED DESCRIPTION

[0022] like Figure 1-3 As shown, the utility model provides a screw sleeve hot forging production line, including a sawing machine 10, a conveyor 20, an intermediate frequency furnace 30, a placement rack 40 and a hot forging machine 50, a truss-type manipulator 60 arranged in sequence, for realizing the continuous transfer of workpieces between the conveyor 20, the intermediate frequency furnace 30 and the placement rack 40, and an articulated robot 70, for transferring the workpiece from the placement rack 40 to the hot forging machine 50 and transferring it out.

[0023] Compared with the prior art, in the screw sleeve hot forging production line provided by the utility model, the workpiece coming out of the sawing machine 10 directly falls onto the conveyor 20 to the designated position, and then the truss-type manipulator 60 directly transfers the workpiece to the corresponding position of the intermediate frequency furnace 30, and after heating and softening, it is transferred to the placement rack 40 by the truss-type manipulator 60 to facilitate the articulated robot 70 to grasp it, and then placed on the hot forging machine 50 for forging. After forging is completed, the workpiece is transferred out and placed at the designated position, so that in the entire processing process, each process is carried out continuously, and the material rack 83 between the sawing machine 10 and the intermediate frequency furnace 30, and between the intermediate frequency furnace 30 and the hot forging machine 50 is omitted, thereby reducing the time occupied by the transfer link and improving production efficiency.

[0024] In one embodiment, the truss manipulator 60 includes a single-arm truss 601 extending from the conveyor 20 to the hot forging machine 50, and at least two three-axis truss manipulators 602 moving along the single-arm truss 601. Specifically, one three-axis truss manipulator 602 performs the action of clamping the workpiece from the conveyor 20 and placing it in the intermediate frequency furnace 30, and the other clamps the workpiece in the intermediate frequency furnace 30 to the placement rack 40, and the operation is repeated in this way, which further reduces the waiting time of the intermediate links and further improves the production efficiency.

[0025] In one embodiment, see Figure 2 The three-axis truss manipulator 602 includes a three-axis driving member, a slewing mechanism 603 and a clamp 604 arranged on the three-axis driving member, and the slewing mechanism 603 drives the clamp 604 to deflect in a vertical plane. In this way, after the clamp 604 clamps the workpiece on the conveyor 20, the slewing mechanism 603 changes the workpiece from a flat state to a vertical state, so that it is convenient to place it on the fixed tooling of the intermediate frequency furnace 30, and the workpiece can also be changed from a vertical state to a flat state, so that it is convenient to place it on the placement rack 40.

[0026] In one embodiment, the rotating mechanism 603 includes: a cylinder with two ends respectively hinged to the three-axis driving member and the clamp 604, and a hinge structure between the three-axis driving member and the clamp 604. Specifically, the clamp 604 rotates around the hinge structure through the extension and contraction of the cylinder, thereby completing the transition of the workpiece between the horizontal state and the vertical state.

[0027] In one embodiment, the clamp 604 is an electric clamp 604 ; in other embodiments, the clamp 604 may also be a pneumatic clamp 604 .

[0028] In one embodiment, see also Figure 2A pusher 21 and a material box 22 are respectively provided on both sides of the conveyor 20, and the pusher 21 is used to push the workpiece to the material box 22. In some cases, when the subsequent process of the sawing machine 10 is slow or a fault occurs, the workpiece on the conveyor 20 is pushed to the material box 22 by the pusher 21 for temporary storage.

[0029] In one embodiment, see Figure 3 The placement rack 40 includes a stand 401 and a grooved plate 402 disposed transversely on the top of the stand 401. The length direction of the grooved plate is parallel to the direction of the production line, and the orientation of the workpiece placed thereon is also parallel to the direction of the production line, which can better adapt to the truss-type manipulator 60. Notches 403 are provided on both sides of the grooved plate 402 to facilitate the articulated robot 70 to grasp the workpiece. The grooved plate 402 is a V-shaped plate or a U-shaped plate, so that the workpiece can be placed more stably.

[0030] In one embodiment, the plurality of intermediate frequency furnaces 30 are distributed along a straight line. In this arrangement, the plurality of intermediate frequency furnaces 30 work simultaneously, which can further speed up the production speed.

[0031] In one embodiment, the screw sleeve hot forging production line further includes a conveyor 2 81, a truss-type manipulator 2 82 and a material rack 83 arranged on one side of the hot forging furnace, which are used to transfer and store the workpiece after the hot end. Specifically, the hot-forged workpiece is placed on the conveyor 2 81 by the articulated robot 70 and transported to a designated location, and then transferred to the material rack 83 by the truss-type manipulator 2 82 for neat stacking, thereby improving the automation level of the production line.
