The material receiving device may be a conventional material receiving manipulator, and considering that the existing material receiving manipulator has relatively more actions, relatively far distance from the screw positioning mold 22 and relatively long taking and placing time, which results in relatively long waiting time of the hot forging machine and affects production efficiency, it is preferable that, in this embodiment, the heating assembly 40 is located above the workbench 21, the receiving device comprises a receiving groove 31 positioned below the output end of the conveying chain 46, a pushing cylinder 32 positioned at one end of the receiving groove 31, a receiving slide rail 33 obliquely arranged relative to the horizontal plane, a support 34 fixedly connected to the workbench 21, a turning frame 35 rotatably connected to the support 34, a turning cylinder 36 for driving the turning frame 35 to rotate, a receiving finger cylinder 37 fixedly connected to the turning frame 35, a receiving support 38 fixedly connected to the workbench 21, a jacking cylinder 39 fixedly connected to the receiving support 38 and with a piston rod vertically arranged upwards, a lifting frame 60 fixedly connected to the piston rod of the jacking cylinder 39, a first sliding seat 61 horizontally and slidably connected to the lifting frame 60, a first motor 62 for driving the first sliding seat 61 to slide, and a first pneumatic clamp 63 fixedly connected to one end of the first sliding seat 61 facing the screw positioning die 22, wherein the transmission connection structure between the first motor 62 and the first sliding seat 61 can be a conventional mechanism, and in the embodiment, the transmission connection between the first motor 62 and the first sliding seat 61 can be realized through a screw rod assembly. The specific transmission connection structure between the overturning cylinder 36 and the overturning frame 35 is as follows: the cylinder body of the turning cylinder 36 is rotatably connected to the workbench 21, the piston rod of the turning cylinder 36 is rotatably connected to the turning frame 35, and the rotating connecting shaft between the piston rod of the turning cylinder 36 and the turning frame 35 and the rotating connecting shaft between the turning frame 35 and the support 34 are arranged in a staggered manner to form a crank link mechanism.

The receiving groove 31 is horizontally arranged and is perpendicular to the conveying chain wheel 46, a piston rod of the pushing cylinder 32 is fixedly connected with a pushing block, and the length direction of the piston rod of the pushing cylinder 32 is the same as the length direction of the receiving groove 31 and penetrates through the receiving groove 31. Preferably, the cross section of the material receiving groove 31 is in a V shape, so that when the supporting seat 48 is driven by the conveying chain 46 to move to the output end position of the conveying chain 46, the supporting seat 48 can rotate around the corresponding chain wheel, and the screw rod on the supporting seat 48 falls into the material receiving groove 31 under the action of gravity, because the cross section of the material receiving groove 31 is in the V shape, the screw rod falling into the material receiving groove 31 can be ensured to be coaxial with the material pushing block or the piston rod of the material pushing cylinder 32, and after the piston rod of the material pushing cylinder 32 is pushed out, the screw rod in the material receiving groove 31 can be pushed out from the material receiving groove 31 under the pushing of the material pushing block.

The upper end of the material receiving slide rail 33 is connected with one end of the material receiving groove 31 far away from the material pushing cylinder 32 so as to receive the screw rod flowing out of the material receiving groove 31 and enable the screw rod to slide down under the action of gravity. The rotating shaft between the turning frame 35 and the support 34 is perpendicular to the material receiving slide rail 33, when the finger rod of the material receiving finger cylinder 37 rotates to a position parallel to the material receiving slide rail 33, the material receiving slide rail 33 is positioned between the two finger rods of the material receiving finger cylinder 37, so that the heated screw rod slides off the material receiving slide rail 33, abuts against the cylinder body of the material receiving finger cylinder 37 and penetrates between the two finger rods of the material receiving finger cylinder 37, and then the material receiving finger cylinder 37 can be used for clamping the screw rod and is turned to the position where the finger rods are vertically arranged upwards, so that the screw rod clamped by the finger cylinder is vertically arranged. Because the roll-over stand 35 drives the material receiving finger cylinder 37 to overturn and needs a certain space, if the distance between the rotating shaft between the roll-over stand 35 and the support 34 and the workbench 21 is increased, although the space required for overturning can be obtained, the up-down stroke of the jacking cylinder 39 also needs to be increased, the movement time is increased, and the production efficiency is influenced.

The screw positioning mold 22 is located on an extension line of a sliding track of the first sliding seat 61, and when the finger rods of the material receiving finger cylinder 37 are arranged vertically upward, a position between the two finger rods of the material receiving finger cylinder 37 (i.e., a position where the clamped screw is located) is located on a vertical plane where a connecting line of the screw positioning mold 21 and the first pneumatic clamp 63 is located. When the device is used, in the process that the material receiving finger cylinder 37 is turned to the position where the finger rods are vertically arranged upwards, the jacking cylinder 39 drives the lifting frame 60 to move upwards, so that when the material receiving finger cylinder 37 is turned to the position where the finger rods are vertically arranged upwards, the first pneumatic clamp 63 and the screw rods clamped by the material receiving finger cylinder 37 are located on the same horizontal plane, then the first motor 62 drives the first sliding seat 61 to drive the first pneumatic clamp 63 to slide towards the direction of the screw rod positioning die 22, in the process, the first pneumatic clamp 63 clamps the screw rods and continuously slides when passing through the position where the screw rods clamped by the material receiving finger cylinder 37 are located, the screw rods are conveyed to the position right above the screw rod positioning die 22, then the jacking cylinder 39 drives the lifting frame 60 to move upwards and downwards, the screw rods are placed in the screw rod positioning die 22, and after the jacking cylinder 39 and the first sliding seat 61 are reset, the screw rods located on the screw rod positioning die 22 are subjected to hot forging processing by using the stamping head.

It should be noted that, when the screw head heating device 10 is used independently, it is also required to be provided with the receiving slot 31, the pushing cylinder 32 and the pushing block in the receiving device, of course, when the screw hot forging machine 20 is used independently, the receiving device is directly arranged on the workbench 21, and at this time, the receiving device may be provided with the receiving slot 31, the pushing cylinder 32 and the pushing block, or may not be provided with the receiving slot 31, the pushing cylinder 32 and the pushing block.

Still inlay on the workstation 21 and be equipped with the stripper 23 of arranging for the horizontal plane slope, through directly inlaying the stripper 23 and establish on workstation 21, can reduce the interval between stripper 21 and the screw rod positioning die 22, the removal stroke when unloading less, further improves production efficiency. In addition, the work table 21 is further provided with a discharging support 70 at a position beside the discharging plate 23, the discharging support 70 is fixedly connected with a discharging cylinder 71 with a piston rod arranged in a vertical direction, a discharging frame 72 is fixedly connected with the piston rod of the discharging cylinder 71, a second sliding seat 73 is horizontally and slidably connected with the discharging frame 72, a second motor 74 for driving the second sliding seat 73 to move is arranged on the discharging frame 72, the second motor 74 is also in transmission connection with the second sliding seat 73 through a conventional screw rod assembly, a second pneumatic clamp 75 is fixedly connected with one end of the second sliding seat 73 facing the screw rod positioning mold 22, the upper end of the discharging plate 23 is located on a vertical surface where a connecting line of the screw rod positioning mold 22 and the second pneumatic clamp 85 is located, so that a screw rod after hot forging can be taken off from the screw rod positioning mold 22 by using the second pneumatic clamp 75 and placed on the discharging plate 23, so that the screw rod slides down along the discharging plate 23 and is collected, the specific discharging action is the same as that of the first pneumatic clamp 63, and the description is not repeated here.

The present invention is described in detail with reference to the attached drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can make various changes and applications of the present invention according to the prior art, which all belong to the protection scope of the present invention.
