[0038] The utility model provides a steel taking machine 100, specifically, please refer to Figures 1 to 3 In this embodiment, the steel-taking machine 100 includes a frame 1, a steel-taking structure 2, a transverse driving mechanism 3 and a lifting driving mechanism 4. The frame 1 is provided with a first workstation and a second workstation spaced apart along the transverse direction; the steel-taking structure 2 includes a steel-taking head 21 movably provided on the frame 1, and the steel-taking head 21 has at least a reciprocating stroke along the up and down directions of the frame 1 and along the transverse direction of the frame 1; the transverse driving mechanism 3 is provided on the frame 1 and connected to the steel-taking structure 2, and the transverse driving mechanism 3 is used to drive the steel-taking structure 2 to move transversely along the frame 1 to move between the first workstation and the second workstation; the lifting driving mechanism 4 is provided on the frame 1 and connected to the steel-taking structure 2, and is used to drive the steel-taking movement so that the steel-taking head 21 can move along the up and down directions of the frame 1.

[0039] In this embodiment, the first station can be the loading position of the steel billet 200, and the second station can be the unloading position of the steel billet 200. The steel billet 200 at the first station is picked up by the steel taking structure 2, and then the steel taking head 21 is moved under the action of the transverse drive mechanism 3 and the lifting drive mechanism 4, and then the steel billet 200 can be transferred from the first station to the second station, thereby realizing the automatic rotation of the steel billet 200 and the higher transportation efficiency of the steel billet 200; and the steel taking head 21 of the steel taking structure 2 can be lifted by the lifting drive mechanism 4, so that the steel billet 200 is not easy to fall during the transportation process and has better stability.

[0040] The frame 1 can be configured as a flat plate, a base, or assembled from steel pipes. The specific form of the frame 1 can be specifically set according to the installation position of the steel taking machine 100 and is not specifically limited here.

[0041] It should be noted that when the steel machine 100 is operating normally, the transverse direction refers to a horizontal direction, and the longitudinal direction refers to a direction perpendicular to the transverse direction on a horizontal plane. If the transverse direction is the left-right direction, then the longitudinal direction is the front-back direction. The first and second workstations are spaced apart in the left-right direction, with the first workstation being located to the right of the second workstation. Unless otherwise specified in this utility model, the description of the relevant directions shall be referred to in this manner.

[0042] Combine Figures 1 to 3As shown, the steel taking structure 2 further includes a steel taking rod 22, which is arranged to extend in the transverse direction of the frame 1. The steel taking head 21 is provided at one end of the steel taking rod 22, and the other end of the steel taking rod 22 is connected to the transverse driving mechanism 3. The lifting driving mechanism 4 is in contact with the portion of the steel taking rod 22 located between the steel taking head 21 and the transverse driving mechanism 3. The transverse driving mechanism 3 can cause the steel taking rod 22 to be displaced in the transverse direction along the frame 1, thereby allowing the steel taking head 21 to reciprocate between the first station and the second station to transfer the steel billet 200. The steel taking head 21 can be lifted and lowered by the lifting drive mechanism 4, so that after picking up the steel billet 200, the steel billet 200 can be slightly lifted to avoid the steel taking rod 22 from colliding with other structures during the transfer process. On the other hand, after the steel taking head 21 is lifted, a certain obstruction can be formed on the steel billet 200 to prevent the steel billet 200 from falling from the steel taking head 21, which is safer.

[0043] Furthermore, if Figure 2 and Figure 3 As shown in , the steel-taking rod 22 includes a first rod segment 221 and a second rod segment 223. The second rod segment 223 is arranged near the steel-taking head 21. The steel-taking head 21 is located at the leftmost end of the steel-taking rod 22. The first rod segment 221 is provided with a rack 222. The rack 222 is arranged to extend along the transverse direction of the frame 1. Preferably, the rack 222 is located at the bottom of the first rod segment 221 of the steel-taking rod 22. The transverse drive mechanism 3 includes a transverse driver 31 and a drive gear 32 connected to the transverse driver 31. The drive gear 32 is meshed with the rack 222. Among them, the transverse drive mechanism 3 can be set as a transverse drive motor, and the transverse drive motor drives the drive gear 32 to rotate, thereby driving the rack 222 to move along the left and right directions of the frame 1, so as to drive the steel taking rod 22 to move along the left and right directions of the frame 1, so that the steel taking head 21 can move to the first workstation to take the steel billet 200, and then move to the second workstation to transfer the steel billet 200 to the second workstation, and so on.

[0044] It is understood that the billet 200 is generally long. If only one support point is provided for taking out the material, the billet 200 is easy to fall and unstable. Figure 1As shown in , a plurality of steel-taking rods 22 are provided, and the plurality of steel-taking rods 22 are arranged in parallel and spaced apart along the longitudinal direction of the frame 1. The plurality of steel-taking rods 22 can be respectively supported at multiple positions of the steel billet 200, thereby making the steel billet 200 more stable after picking up the steel billet 200. Correspondingly, a plurality of driving gears 32 are provided, and the plurality of driving gears 32 are arranged in a one-to-one correspondence with the plurality of steel-taking rods 22. The plurality of driving gears 32 are connected to the same transverse driver 31, and the same transverse driver 31 can simultaneously drive the plurality of steel-taking rods 22 to move in the left and right directions of the frame 1, thereby better maintaining the synchronization of the plurality of steel-taking rods 22 and saving energy.

[0045] Preferably, the lifting drive mechanism 4 is also provided with multiple, and the multiple lifting drive mechanisms 4 are arranged in a one-to-one correspondence with the multiple steel-taking rods 22. The multiple lifting drive mechanisms 4 are used to simultaneously drive the multiple steel-taking rods 22 to move, so as to better lift and lower the steel billet 200, thereby ensuring a better picking and placing effect.

[0046] It is understandable that the steel billet 200 is easy to roll when placed on a flat surface. If the steel bar 22 is fixed too firmly after picking up the steel billet 200, the operation of placing the steel billet 200 will be more complicated. Alternatively, if the steel billet 200 is clamped by a clamping method, more driving mechanisms will be required to drive the clamping claws, making the structure of the steel taking machine 100 more complicated and costly. In this embodiment, preferably, combined with Figure 2 and Figure 3 As shown, the lifting drive mechanism 4 includes a lifting drive 41 and a rocker structure rotatably provided at one end on the frame 1, the other end of the rocker structure abutting against the steel-taking rod 22, and the lifting drive 41 is connected to the rocker structure and is used to drive the rocker structure to rotate, so that the rocker structure can abut against the steel-taking rod 22, so that the steel-taking rod 22 can rotate relative to the frame 1 and the steel-taking head 21 can move in the up and down direction of the frame 1. The steel-taking rod 22 is rotated, and after picking up the steel billet 200, one end of the steel-taking head 21 can be lifted, so that the surface holding the steel billet 200 is tilted, so that the steel billet 200 can be firmly restricted on the steel-taking head 21 under the limiting action of the inclined surface. The structure is simple and can ensure that the steel billet 200 will not fall on the steel-taking head 21.

[0047] Furthermore, a limiting slot is provided on the second rod segment 223. The limiting slot extends transversely along the frame 1, that is, along the left-right direction of the steel-taking rod 22. The rocker arm structure includes a rocker 42 and a roller 43 provided at a first end of the rocker 42. The second end of the rocker 42 is rotatably connected to the frame 1. The lifting drive 41 is hinged to one side of the rocker 42, and the roller 43 is retained in the limiting slot. The lifting drive 41 drives the rocker 42 to rotate, so that the roller 43 can abut against the steel-taking rod 22, thereby lifting or lowering the end of the steel-taking rod 22 corresponding to the steel-taking head 21, thereby lifting or lowering the steel billet 200. Moreover, the limiting slot can limit the roller 43 in the front-to-back direction, preventing the steel-taking rod 22 from shaking during the lifting or lowering process, thereby improving stability.

[0048] Preferably, the lifting drive 41 is configured as a driving cylinder. When the steel taking head 21 is in the lowest position, the steel taking rod 22 is horizontally arranged, and the roller 43 is located at the leftmost end of the limiting groove. When the steel taking head 21 is in the highest position, the rocker 42 is nearly vertically arranged. Of course, the rotation range of the rocker 42 can be set according to the specific size of the steel taking machine 100. The driving cylinder is connected to the right side of the rocker 42. When the driving cylinder is extended, it can push the rocker 42 to rotate toward the lowest position. When the driving cylinder is retracted, it can push the rocker 42 to rotate toward the highest position.

[0049] Of course, in order to more accurately control the rotation range of the rocker 42, the steel taking machine 100 further includes a lifting detection mechanism 5, which is used to detect the position of the rocker 42, so as to accurately determine the position of the rocker 42 and the position of the steel taking head 21.

[0050] Preferably, combined Figure 4 and Figure 5 As shown, the lifting detection mechanism 5 includes a detection plate 51, a first trigger switch 52 and a second trigger switch 53. The detection plate 51 is coaxially connected to the second end of the rocker 42 and can rotate together with the rocker 42; the first trigger switch 52 and the second trigger switch 53 are arranged on the frame 1. When the first trigger switch 52 contacts the detection plate 51, the rocker 42 is in the first position, the steel taking head 21 is in the lowest position, and the steel taking rod 22 is arranged horizontally; when the second trigger switch 53 contacts the detection plate 51, the rocker 42 is in the second position, as shown in FIG. Figure 4 The middle dotted line shows the position of the roller 43 ′ when the rocker 42 is in the second position, the steel taking head 21 is in the highest position, and the steel taking head 21 of the steel taking rod 22 is in a raised state.

[0051] Specifically, the steel taking machine 100 may further include a controller, which is electrically connected to the first trigger switch 52, the second trigger switch 53, the transverse driver 31 and the lifting driver 41. When the first trigger switch 52 contacts the detection plate 51, the steel taking head 21 is at the lowest position. At this time, the transverse driver 31 can be controlled to work to take the steel billet 200. After the steel billet 200 is placed on the steel taking head 21, the lifting driver 41 is controlled to work so that the rocker 42 rotates. When the second trigger switch 53 contacts the detection plate 51, as shown in FIG. Figure 4 The detection rod 51' represented by the dotted line is in the position when the rocker 42 is in the second position, and the lifting drive 41 is controlled to stop working and the transverse drive 31 is turned on. After the steel-taking head 21 is driven to the second workstation by the transverse drive 31, the transverse drive 31 is controlled to stop working and the lifting drive 41 is turned on to flatten the steel-taking rod 22 and place the steel billet 200 at the second workstation.

[0052] Of course, a lateral displacement detection mechanism may also be provided, which is similar to the working principle of the lifting detection mechanism 5 , and the lateral position of the steel-taking rod 22 may be detected by the lateral displacement detection mechanism.

[0053] For the steel head 21, Figure 2 and Figure 3 As shown, the steel taking head 21 includes a mounting seat 211 and a supporting plate 212 arranged on the mounting seat 211, wherein the top of the mounting seat 211 is flush with the top of the steel taking rod 22, and the supporting plate 212 is used to support steel parts, and the setting height of the supporting plate 212 is lower than the top of the mounting seat 211, so that the steel billet 200 will not fall out from the top of the mounting seat 211 after being placed on the supporting plate 212, and the limiting amount is larger and the stability is better.

[0054] Preferably, a mounting groove is formed on the mounting seat 211, and the mounting groove is arranged in an "L" shape. The mounting groove has a groove bottom wall 2111 and a groove side wall 2112 standing on the side of the groove bottom wall 2111 close to the steel-taking rod 22. The shape of the supporting plate 212 is adapted to the shape of the mounting groove to better fit the mounting groove. Moreover, after the steel-taking head 21 is raised, the bottom wall of the supporting plate 212 is in an inclined state, so that after the steel billet 200 is placed on the supporting plate 212, the steel billet 200 can be limited by the bottom wall and side walls of the supporting plate 212, thereby being more stable and not easy to fall.

[0055] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
