[0002] During the production process of round steel, when the long round steel enters the cold shearing machine for cutting, the temperature of the round steel is about 500 degrees Celsius. A funnel-shaped receiving box is installed below the cutting tool assembly of the cold shearing machine, and the cut round steel falls into the receiving box.

[0003] During the production process of round steel, it is usually necessary to sample the round steel cut by the cold shearing machine and detect the round steel to determine whether the composition of the round steel is qualified. The current sampling method is that a worker holds a receiving box and extends the receiving box into the cold shearing machine on one side of the cutting tool assembly. In this way, the cut round steel directly falls into the receiving box, and then the receiving box is withdrawn from the cold shearing machine, and the round steel in the receiving box is put into a transfer box. Finally, the transfer box is sent to the composition detection area for composition detection.

[0037] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0038] As Figures 1 - 6 shown, an embodiment of the present utility model provides a steel sampling device, including a linear drive assembly, a carrying box 6, and a flip drive mechanism 5. The carrying box 6 is installed on the linear drive assembly; when the linear drive assembly is in the first working state, the linear drive assembly drives the carrying box 6 to extend downward along the first direction under the cutting blade assembly of the cold shearing machine 1 to receive the cut steel; when the linear drive assembly is in the second working state, the linear drive assembly drives the carrying box 6 to move along the second direction to withdraw from the cold shearing machine 1; the first direction and the second direction are opposite; the flip drive mechanism 5 is installed on the linear drive assembly and is connected to the carrying box 6. When the flip drive mechanism 5 is in the flip mode, the flip drive mechanism 5 drives the carrying box 6 to rotate clockwise to turn out the steel in the carrying box 6; when the flip drive mechanism 5 is in the reset mode, the flip drive mechanism 5 drives the carrying box 6 to rotate counterclockwise to make the carrying box 6 return to the upright position.

[0039] In this embodiment, as Figure 1 shown, the steel sampling device 2 is arranged on the front of the cold shearing machine 1, so that the length direction of the steel sampling device 2 is perpendicular to the feeding direction of the cold shearing machine 1, and it is ensured that the linear drive assembly is close to the cutting blade assembly of the cold shearing machine 1. Among them, the first direction is Figure 1 the direction perpendicular to the paper surface and facing inwards in

[0040] During sampling, the linear drive assembly drives the carrier box 6 to move towards the cold shear 1, so that the carrier box 6 extends into the cold shear 1 and moves to one side of the cutter assembly. When the cutter assembly cuts the round bar, the cut round bar directly falls into the carrier box 6. Then, the linear drive assembly drives the carrier box 6 to move away from the cold shear 1, so that the carrier box 6 is removed from the cold shear 1. After the carrier box 6 moves to the designated position, the flipping drive mechanism 5 drives the carrier box 6 to rotate clockwise to turn out the steel in the carrier box 6, and the steel thus falls into the pre-arranged collection box. Subsequently, the flipping drive mechanism 5 drives the carrier box 6 to rotate counterclockwise to make the carrier box 6 return to the upright position, and then the above steps are repeated for the next sampling operation.

[0041] In this way, manual material taking is not required, which avoids scalding workers by the high-temperature round bar, improves the safety of sampling, and since manual operation is not required, it saves time and effort, reduces the labor burden of workers, and improves the sampling efficiency.

[0042] As a preferred embodiment, as Figure 2 shown, the linear drive assembly includes a machine frame 3, a sliding seat 4 and a drive mechanism. Among them, one end of the machine frame 3 close to the cold shear 1 extends into the cold shear 1 and is close to the cutter assembly, and the length direction of the machine frame 3 is perpendicular to the incoming material direction of the cold shear 1. The sliding seat 4 is slidably installed on the right side surface of the machine frame 3, that is, the sliding seat 4 can slide along the length direction of the machine frame 3. Further, the carrier box 6 is in a long strip shape, the carrier box 6 is installed on the sliding seat 4, and the length direction of the carrier box 6 is the same as the length direction of the machine frame 3. The drive mechanism is installed inside the machine frame 3 to drive the sliding seat 4 to move along the length direction of the machine frame 3 to drive the carrier box 6 to extend into or withdraw from the cold shear 1.

[0043] It should be noted that the cutter assembly in the cold shear 1 includes a lower knife seat and an upper cutter. The upper knife seat and the lower cutter are arranged staggeredly, and the upper cutter punches downward to cut the round steel on the lower knife seat. And the end of this machine frame 3 close to the cold shear 1 is located on the right side of the lower knife seat and close to the lower knife seat. During sampling, the drive mechanism drives the sliding seat 4 to move towards the cold shear 1, thereby driving the carrier box 6 to move to the right side of the lower knife seat and slightly lower than the lower knife seat. Then the upper cutter punches to cut the round steel, and the cut round steel directly falls onto the carrier box 6. Subsequently, the drive mechanism drives the sliding seat 4 to move away from the cold shear 1, thereby driving the carrier box 6 to be removed from the cold shear 1.

[0044] It can be seen that in this embodiment, automatic sampling can be realized, manual sampling is not required, the safety of sampling is improved, and the sampling efficiency is improved.

[0045] Preferably, as Figure 2 and Figure 4As shown in the figure, the frame 3 has a long strip-shaped rectangular frame structure. On the front panel 301 on the right side of the frame 3, an upper hole body 302 and a lower hole body 303 are successively arranged along its length direction. The widths and lengths of the upper hole body 302 and the lower hole body 303 are the same. Both the upper hole body 302 and the lower hole body 303 are long holes. The lengths of the upper hole body 302 and the lower hole body 303 are slightly smaller than the length of the front panel 301, and the upper hole body 302 is located above the lower hole body 303. Further, a first guide rail 9 is installed on the inner bottom wall of the upper hole body 302, and a second guide rail 10 is installed on the inner bottom wall of the lower hole body 303. The first guide rail 9 and the second guide rail 10 are exactly the same, and the length of the first guide rail 9 is slightly smaller than the length of the upper hole body 302.

[0046] Further, as Figure 5 and Figure 6 shown in the figure, a first roller 403 and a second roller 404 are installed on the back surface of the sliding seat 4. The first roller 403 is located above the second roller 404. The distance between the first guide rail 9 and the second guide rail 10 is the same as the distance between the first roller 403 and the second roller 404. When installing the sliding seat 4, the first roller 403 on the back surface of the sliding seat 4 can rest on the first guide rail 9, and at the same time, the second roller 404 can rest on the second guide rail 10.

[0047] It should be noted that the cross-sections of the first guide rail 9 and the second guide rail 10 are convex-shaped. The first roller 403 and the second roller 404 both include a shaft body and rim portions located on both sides of the shaft body. The inner walls of the two rim portions on the first roller 403 are attached to both sides of the top of the first guide rail 9, and the inner walls of the two rim portions on the second roller 404 are attached to both sides of the top of the second guide rail 10. The purpose of such a setting is as follows: First, the friction between the sliding seat 4 and the frame 3 is changed into rolling friction, reducing the frictional force and improving the moving efficiency. Second, the rim portions on the rollers are limited by the guide rails, and the rollers cannot be separated from the guide rails, so that the sliding seat 4 can be suspended, preventing the sliding seat 4 from being separated from the frame 3.

[0048] Preferably, as Figure 3 shown in the figure, the driving mechanism includes a driving sprocket 13, a driven sprocket 14, a chain, and a driving motor 12. Among them, the driving sprocket 13 is installed inside the frame 3 at one end far from the cold shear machine 1, the driven sprocket 14 is installed inside the frame 3 at one end close to the cold shear machine 1, the chain is installed between the driving sprocket 13 and the driven sprocket 14 in a transmission manner, the driving motor 12 is fixedly installed on the back surface of the frame 3, and the output end of the driving motor 12 is connected to the driven sprocket 14. A connecting member 402 for connecting with the chain is installed on the back surface of the sliding seat 4. The connecting member 402 is at the same height as the first roller 403, and the connecting member 402 extends into the upper hole body 302.

[0049] When the output shaft of the driving motor 12 drives the driving sprocket 13 to rotate, the driving sprocket 13 drives the chain and the driven sprocket 14 to rotate. Since the back surface of the sliding seat 4 is connected to the upper half of the chain through the connecting piece 402, with the rotation of the chain, the sliding seat 4 can be driven to move along the movement of the chain, so as to drive the carrying box 6 to extend into or withdraw from the cold shear 1.

[0050] It should be noted that shafts for installing sprockets are respectively rotatably installed at both ends inside the machine frame 3, and the two sprockets are respectively connected to the two shafts.

[0051] In addition, a speed reducer is installed on the back surface of the machine frame 3. The shaft cooperating with the driven sprocket 14 is connected to the output end of the speed reducer, and the input end of the speed reducer is connected to the output end of the driving motor 12.

[0052] In order to facilitate pouring out the steel in the carrying box 6, so as to pour the steel onto the transfer tool, the collection box or onto the conveyor, and then the steel is transported to the component detection area through the transfer tool, the collection box or the conveyor. Preferably, as Figure 2 shown, a flipping drive mechanism 5 is installed on the front surface of the sliding seat 4, and the carrying box 6 is flipped through the flipping drive mechanism 5 to pour out the steel in the carrying box 6.

[0053] Specifically, as Figure 5 shown, the flipping drive mechanism 5 includes a flipping motor 501, a coupling 502 and a drive shaft 503. The flipping motor 501 is fixedly installed on the front surface of the sliding seat 4 through an L-shaped angle seat. A rectangular frame is fixedly installed on the front surface of the sliding seat 4. Bearings are respectively installed on both sides of the left side of the rectangular frame. The drive shaft 503 passes through the two bearings. One end of the drive shaft 503 close to the flipping motor 501 is connected to the output end of the flipping motor 501 through the coupling 502, and one end of the drive shaft 503 close to the carrying box 6 is detachably connected to the carrying box 6 through a flange.

[0054] In this way, when it is necessary to pour out the round steel in the carrying box 6, the flipping motor 501 drives the coupling 502 and the drive shaft 503 to rotate, and finally drives the carrying box 6 to rotate together, so as to turn out the round steel in the carrying box 6 onto the collection box, the transfer tool or the conveyor.

[0055] In this embodiment, the steel sampling device 2 further includes a controller. The flipping motor 501 and the driving motor 12 are both signal-connected to the controller. By controlling the operation of the driving motor 12 and the flipping motor 501 through the controller, the whole sampling action is programmed, ensuring that the sampling is more efficient and accurate.

[0056] In order to better detect whether the carrying box 6 is in place, as Figure 2As shown in the figure, a proximity switch 11 is installed at the top of one end of the machine frame 3 extending into the cold shear 1, and a signal trigger 401 is installed at the top position on the front of the sliding seat 4. In this way, when the sliding seat 4 drives the bearing box 6 to move towards the inside of the cold shear 1 to a set position, at this time, the signal trigger 401 just moves to the proximity switch 11, and the proximity switch 11 quickly issues an electrical command, and the controller controls the drive motor 12 to pause and wait for the cutting tool assembly to cut the round steel. At this time, the bearing box 6 can just hold all the cut round steel.

[0057] Optionally, when helping the bearing box 6 to retract to a fixed position to make the blanking position fixed. A proximity switch 11 can be installed at one end of the machine frame 3 away from the cold shear 1 to help the bearing box 6 stop at the set position every time it retracts.

[0058] As Figure 2 shown in the figure, a drag chain carrier 7 for accommodating a drag chain 8 is installed on the top of the machine frame 3 along its length direction. A drag chain connecting piece in the shape of an inverted L-shaped plate is installed on the sliding seat 4. One end of the drag chain 8 in the drag chain carrier 7 is connected to the drag chain connecting piece.

[0059] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0060] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the connection inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0061] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
