The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 shows a loading and unloading device 1 for a thread rolling machine according to a preferred embodiment of the present invention, which includes: a feeding mechanism 11 and a pushing mechanism 12 one by one.

Referring to fig. 3, the root-by-root feeding mechanism 11 includes: a first lifting drive mechanism 111, a lifting plate 112 which is connected with the first lifting drive mechanism 111 in a driving way and extends along the height direction, and an inclined blanking plate 113 which is arranged obliquely relative to the horizontal plane (see fig. 2). The first elevation driving mechanism 111 is used for conveying the workpiece 2 held on the top of the elevation plate 112 to the inclined blanking plate 113, so that the workpiece 2 slides down from the top of the inclined blanking plate 113 to the pushing mechanism 12. In order to lift the workpieces 2 one by one, the lifting plate 112 preferably extends in a vertical height direction (i.e. is arranged vertically, but it is of course also possible to incline at an angle, i.e. extends in an inclined height direction), so that the thickness of the lifting plate 112 depends on the diameter of the workpiece 2, and lifting plates 112 of different thicknesses can be replaced if necessary.

Referring to fig. 4 and 5, the pusher mechanism 12 includes: the second lifting driving mechanism 121, the lifting frame 122 which is in driving connection with the second lifting driving mechanism 121 and is provided with a horizontal conveying groove 1221, a horizontal linear material pushing driving mechanism 123 arranged on the lifting frame 122, a material pushing rod 124 which is in driving connection with the horizontal linear material pushing driving mechanism 123 and is movably inserted in the horizontal conveying groove 1221, and a material discharging conveying mechanism 125 which is positioned right above or right below the lifting frame 122.

Referring to fig. 5, the inclined blanking plate 113 is used for transferring the workpiece 2 to the horizontal conveying groove 1221, the pushing rod 124 is used for feeding the workpiece 2 in the horizontal conveying groove 1221 into the thread rolling machine, and the discharging conveying mechanism 125 is used for blanking the workpiece 2 fed out by the thread rolling machine.

In operation, referring to fig. 2, the lifting plate 112 is lowered to the lowest point, the workpieces 2 are firstly stacked on the inclined material preparation plate 114, and the workpiece 2 closest to the lifting plate 112 slides down to the top of the lifting plate 112 under the driving of the gravity of the workpiece 2. Then, referring to fig. 3, the first elevation driving mechanism 111 drives the elevation plate 112 to ascend and lift up one workpiece 2 until the workpiece 2 slides down to the inclined blanking plate 113 (see fig. 2). At this point, the workpieces 2 are ready to enter the pusher 12 from the feed mechanism 11 one by one. Referring to fig. 5, the workpiece 2 falls into the horizontal conveying groove 1221, and the pushing rod 124 is driven to move by the horizontal straight line pushing driving mechanism 123, so that the workpiece 2 is fed into the thread rolling machine from the horizontal conveying groove 1221 for straight thread rolling. Based on the fact that the horizontal conveying groove 1221 must be as high as the inlet and outlet of the screw rolling machine, therefore, in order to prevent the screw rolling machine from falling into the horizontal conveying groove 1221 when the screw rolling machine rolls out the workpiece 2 or colliding with the lifting frame 122, and causing the workpiece to fail to fall into the discharging conveying mechanism 125, the second lifting driving mechanism 121 needs to immediately drive the lifting frame 122 to ascend or descend so as to avoid the inlet and outlet of the screw rolling machine, so that the workpiece 2 (i.e. the workpiece 2 after the straight thread rolling is finished) after coming out of the screw rolling machine falls into the discharging conveying mechanism 125, and is sent out through the discharging conveying mechanism 125. Thus, the mechanized feeding and discharging of the thread rolling machine are completed.

It should be added that, in essence, the relative positional relationship between the outfeed conveyor 125 and the crane 122 will determine the sequence of operation and the positional relationship of some of the components. That is, in the present embodiment, referring to fig. 5, the outfeed conveyor 125 is provided directly below the crane 122; at this time, the level of the discharging and conveying mechanism 125 is lower than the inlet and outlet of the thread rolling machine; when the lifting frame 122 is lifted, the horizontal conveying groove 1221 is connected with the inclined blanking plate 113 and is slightly lower than the lower end of the inclined blanking plate 113, so that the workpiece 2 can conveniently slide down to the horizontal conveying groove 1221 from the inclined blanking plate 113; particularly, at this time, the horizontal height of the horizontal conveying groove 1221 is greater than the inlet and outlet of the screw rolling machine, that is, the horizontal conveying groove 1221 is avoiding the inlet and outlet of the screw rolling machine, so that the inlet and outlet of the screw rolling machine can horizontally eject the processed workpiece 2, and then the workpiece 2 falls to the discharging and conveying mechanism 125 and is discharged through the discharging and conveying mechanism 125. After understanding the actual arrangement of the present embodiment, the arrangement (i.e., alternative arrangement) of the discharging conveyor 125 directly above the crane 122 will be explained: at this time, it is necessary that the discharging conveyor 125 should be installed on the lifting frame 122 to be lifted and lowered synchronously, and, at this time, the horizontal transfer groove 1221 is first lowered to engage with the inclined blanking plate 113, so that the workpiece 2 slides down from the inclined blanking plate 113 to the horizontal conveying groove 1221 (at this time, the horizontal conveying groove 1221 is also avoiding the inlet and outlet of the thread rolling machine, so that the inlet and outlet of the thread rolling machine can horizontally eject the workpiece 2 to the discharging conveying mechanism 125 to be ejected through the discharging conveying mechanism 125), the horizontal conveyor 1221 is then raised (the outfeed conveyor 125 is raised synchronously so that it is higher than the infeed and outfeed ports of the thread roller, so that it is in the infeed position rather than the outfeed position), until it is level with the infeed and outfeed ports of the thread roller, then the material pushing rod 124 pushes the workpiece 2 into the thread rolling machine for processing, and immediately after that, the horizontal conveying groove 1221 immediately descends to avoid and carry the next workpiece 2.

Obviously, the lifting plate 112 is driven by the first lifting driving mechanism 111 of the feeding mechanism 11 one by one, so that the lifting plate 112 sends the workpiece 2 to the inclined discharging plate 113, then the workpiece 2 slides to the horizontal conveying groove 1221 of the pushing mechanism 12 on the inclined discharging plate 113 by using the gravity of the workpiece 2, then the workpiece 2 is pushed into the thread rolling machine for processing by the pushing rod 124, and the lifting frame 122 is driven by the second lifting driving mechanism 121 to avoid the inlet and the outlet of the thread rolling machine, so that the processed workpiece 2 can be popped out to the discharging conveying mechanism 125 by the thread rolling machine, that is, the operation mechanism of the thread rolling machine is reasonably utilized, the feeding and discharging work is mechanically completed, the labor force is reduced, and the production efficiency is improved.

Preferably, referring to fig. 5, the discharging conveyor 125 includes a motor, at least two conveyor bars 1251 in a closed loop structure and in driving connection with the motor, the two conveyor bars 1251 are spaced apart to form a material loading slot 1252 therebetween, and the material loading slot 1252 is used for loading and guiding the workpiece 2. Set up like this, be the mode of having combined the screw roller ejection of compact ingeniously, carry out sharp bearing and continue to carry through carrying material groove 1252 to work piece 2 promptly to prevent that work piece 2 from rolling on ejection of compact conveying mechanism 125, in order to prevent that work piece 2 from dropping. It is understood that alternatively, outfeed conveyor mechanism 125 may be a conventional conveyor or the like.

Preferably, referring to fig. 5, the outfeed conveyor mechanism 125 further comprises an outfeed chute 1253, the conveyor bar 1251 being disposed within the outfeed chute 1253; two opposite sides of the top of the discharge chute 1253 are respectively provided with an inclined limiting plate 1254, and the extending direction of the inclined limiting plates 1254 is consistent with the extending direction of the discharge chute 1253. By the arrangement, the fault tolerance rate of the discharge of the thread rolling machine can be improved, and even if an unexpected condition occurs, a certain workpiece 2 has a certain inclination when being bombed out, and the workpiece 2 can be corrected in direction and fall into the material carrying groove 1252 under the guidance of the inclined limiting plate 1254.

Preferably, referring to fig. 5, the pushing mechanism 12 further includes a guide seat 126 disposed on the lifting frame 122 and having a guide hole, a guide rod 127 movably inserted into the guide hole, and a linkage block 128 fixedly connected to the guide rod 127 (see fig. 4). The horizontal linear pushing driving mechanism 123 is in driving connection with the pushing rod 124 through a linkage block 128. The arrangement is that the guide seat 126 is used for guiding, so that the bearing capacity of the horizontal linear pushing driving mechanism 123 is reduced to improve the running precision of the horizontal linear pushing driving mechanism.

Referring to fig. 5, in order to prevent the workpiece 2 from falling off the inclined blanking plate 113 due to too large inertia force to escape from the horizontal conveying groove 1221, it is preferable that the lifting frame 122 is provided with a material blocking block 1222, and the material blocking block 1222 is located on the side of the horizontal conveying groove 1221 away from the inclined blanking plate 113.

So arranged, the workpieces 2 will approach the lifting plate 112 by their own weight until one of the workpieces 2 in the front row rolls down to the top of the lifting plate 112.

By such an arrangement, the workpiece 2 can be prevented from directly sliding off the inclined blanking plate 113, in this embodiment, when the horizontal conveying groove 1221 needs to be waited to rise to be engaged with the inclined blanking plate 113, the material blocking plate 118 is lifted again, so that the workpiece 2 can slide off the horizontal conveying groove 1221. It should be understood that the power for lifting the inclined blanking plate 113 may be another power source, and in the embodiment, the original power source is preferably used: referring to fig. 5, a lifting rod 13 is fixedly connected to the rotating shaft 117, a return spring 14 is connected to the swing end of the lifting rod 13, and an end of the return spring 14 far away from the lifting rod 13 is connected to the frame 116.
