Description

Technical Field

[0001] The present invention relates to the technical field of bar racks, and in particular to a bar receiving rack for a straightening and calendering machine. Background Art

[0002] A straightening and calendering machine is a device for straightening metal profiles, bars, tubes, wires, etc. The straightening machine extrudes bars and the like through straightening rollers to change their straightness. After the bar products are bitten by the rollers, they continuously move linearly or rotationally, so that the products are subjected to various deformations such as compression, bending, and flattening, and finally the purpose of straightening is achieved.

[0003] For the bars output from the straightening machine after straightening, usually a storage rack is directly used to collect them. During the collection process, the bars are usually stacked together. For some slender bars, due to their certain flexibility, it is very easy to bend. For example, the longer the common steel bar, the easier it is to bend. When the bars are stacked, it is very easy for the bars to bend or be placed on another bar. For example, as shown in Figure 9 In this case, if the deviation is not corrected and the bars are straightened in time, when the subsequent bars continue to be stacked, due to the action of pressure, it is very easy for this bar and other bars in contact with it to deform due to uneven stress, making the previous straightening work useless, and subsequent re-straightening is required. Therefore, a bar receiving rack for a straightening and calendering machine is proposed. Summary of the Invention

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a bar material receiving rack for a straightening and calendering machine, including a flipping receiving mechanism 1, a limiting and buffering mechanism 2 is installed on the flipping receiving mechanism 1, and a plurality of storage mechanisms 3 distributed linearly are arranged on one side of the flipping receiving mechanism 1. The same deviation rectifying and straightening assembly 4 is arranged between two adjacent storage mechanisms 3. The flipping receiving mechanism 1 is used to receive the bar workpiece 5 output from the straightening and calendering machine and transfer the bar workpiece 5 to a plurality of storage mechanisms 3 for stacking through flipping. The plurality of deviation rectifying and straightening assemblies 4 are used to rectify and straighten the bar workpieces 5 that are staggered and stacked and bent on the storage mechanisms 3, so that the stacked bar workpieces 5 are kept parallel to each other.

[0028] Further, as Figure 1 shown, the bar workpiece 5 output from the straightening and calendering machine falls on the flipping receiving mechanism 1 from left to right.

[0029] The storage mechanism 3 includes a mounting frame 31 with an open top. A sloping buffer plate 34 is fixedly installed at the top end of the mounting frame 31 close to the flipping receiving mechanism 1. Two rollers 32 are rotatably installed through the mounting frame 31. Flexible belts 33 are arranged on both sides of the mounting frame 31, and both ends of the two flexible belts 33 are respectively sleeved on the corresponding rollers 32.

[0030] The deviation rectifying and straightening assembly 4 includes a gear-rack linear module 41. A sliding frame 42 is fixedly installed on the slider of the gear-rack linear module 41. A sliding plate 43 is slidably installed in the sliding frame 42. The top of the sliding plate 43 extends outside the sliding frame 42. A cross plate 44 and an adjusting plate 45 are fixedly connected to the top end of the sliding plate 43. A plurality of straightening mechanisms 48 are arranged linearly on the cross plate 44.

[0031] The straightening mechanism 48 includes a prism 481 that penetrates the cross plate 44 and is slidably connected to the cross plate 44. A top plate 484 and a wheel frame 482 are fixedly installed at the top and bottom ends of the prism 481 respectively. A V-shaped wheel 483 is rotatably installed in the wheel frame 482. A return spring 485 is slidably sleeved on the prism 481, and both ends of the return spring 485 are fixedly connected to the bottom of the top plate 484 and the top of the cross plate 44 respectively.

[0032] Further, the wheel carriers 482 on two adjacent straightening mechanisms 48 are slidably connected. When the V-shaped wheels 483 abut against the bar workpiece 5, if the bar workpiece 5 does not deform or bend, the V-shaped wheels 483 will only exert a downward pressure on the bar workpiece 5 and will not cause the bar workpiece 5 to move radially. When encountering a bent part on the bar workpiece 5, the linearly moving V-shaped wheels 483 will automatically correct and straighten it, enabling the bent part of the bar workpiece 5 to move radially. At this time, the positions of the corresponding V-shaped wheels 483 will move up and down. Eventually, the bar workpiece 5 that has undergone bending deformation and other bar workpieces 5 stacked orderly below it can all be kept parallel.

[0033] The connection between the cross plate 44 and the adjusting plate 45 is hinged to the top end of the sliding plate 43. An expansion cylinder two 46 is hinged between the sliding plate 43 and the adjusting plate 45. Expansion cylinders three 47 are fixedly installed on both sides of the sliding frame 42, and the piston rod ends of the two expansion cylinders three 47 are fixedly connected to both sides of the sliding plate 43 respectively.

[0034] Further, by controlling the expansion and contraction of the expansion cylinder two 46, the adjusting plate 45 can drive the cross plate 44 to rotate with the top end of the sliding plate 43 as the center. By controlling the expansion and contraction of the two expansion cylinders three 47, the height of the cross plate 44 can be controlled, and the cross plate 44 can be driven to move left and right by the gear-rack linear module 41.

[0035] The flipping and receiving mechanism 1 includes two legs 11. The same cross frame 12 with adjustable height is installed on the two legs 11. A triangular plate 13 is provided above the cross frame 12. The cross frame 12 and the triangular plate 13 are connected by a plurality of hinges 15 distributed at equal intervals. Two fixed seats 17 are fixedly installed on the cross frame 12, and expansion cylinders one 18 are hinged between the two fixed seats 17 and the triangular plate 13 respectively.

[0036] Further, by controlling the expansion and contraction of the two expansion cylinders one 18, the triangular plate 13 can be driven to rotate on the cross frame 12 with the centers of the plurality of hinges 15 as the center, so as to complete receiving the bar workpiece 5 after straightening from the straightening and calendering machine by the triangular plate 13, and flipping and transferring the received bar workpiece 5 to the plurality of storage mechanisms 3.

[0037] The limiting and buffering mechanism 2 includes a frame 21 sleeved on the triangular plate 13. An adjusting screw 22 is threadedly installed through the frame 21. The limiting and buffering mechanism 2 further includes a positioning block 23 arranged in the triangular plate 13. The bottom end of the adjusting screw 22 is rotatably connected to the positioning block 23. A spring telescopic rod 24 is fixedly installed through the positioning block 23. The piston rod end of the spring telescopic rod 24 is fixedly installed with a guide rod 26. Two baffle plates 25 are slidably installed through the positioning block 23, and both baffle plates 25 are fixedly connected to the guide rod 26.

[0038] One end of the triangular plate 13 close to the straightening and calendering machine is fixedly installed with a wide-mouth plate 14, and a plurality of stop rods 16 are fixedly installed on the side of the triangular plate 13 away from the plurality of material storage mechanisms 3.

[0039] Furthermore, after the bar workpiece 5 is discharged from the straightening and calendering machine, it still has a certain inertia during the process of entering the triangular plate 13 through the wide-mouth plate 14. By setting the guide rod 26, not only can it prevent the bar workpiece 5 from sliding out of the triangular plate 13, but also the impact caused by the bar workpiece 5 on the guide rod 26 can be buffered by the spring telescopic rod 24.

[0040] In addition, by turning the adjusting screw 22 to disengage the positioning block 23 from the triangular plate 13, then, at this time, the frame 21 can also move freely outside the triangular plate 13. When reaching the target position on the triangular plate 13, the adjusting screw 22 can be turned to make the positioning block 23 and the frame 21 tightly abut against the triangular plate 13, and the limit buffering mechanism 2 can be fixed on the triangular plate 13. Therefore, the position of the limit buffering mechanism 2 relative to the wide-mouth plate 14 can be adjusted according to the different lengths of the bar workpiece 5.

[0041] Furthermore, by setting a plurality of stop rods 16, it can prevent the bar workpiece 5 from not being flipped and transferred out of the triangular plate 13 along the target path during the process of flipping the triangular plate 13.

[0042] In this embodiment: After the bar workpiece 5 is straightened and calendered, it will be transported to the triangular plate 13, and then the bar workpiece 5 is transferred to the plurality of material storage mechanisms 3 by controlling the flipping of the triangular plate 13, and the bar workpiece 5 falls on the two flexible belts 33 of each material storage mechanism 3.

[0043] When the triangular plate 13 flips and transfers the bar workpiece 5 to the plurality of material storage mechanisms 3, the second telescopic cylinders 46 on the plurality of deviation rectifying and straightening assemblies 4 are in a contracted state. At this time, one end of the cross plate 44 away from the adjusting plate 45 will tilt upward. At this time, the deviation rectifying and straightening assembly 4 will not hinder the transfer of the bar workpiece 5 from the triangular plate 13 to the plurality of material storage mechanisms 3. After the bar workpiece 5 falls on the plurality of material storage mechanisms 3, then synchronously control the second telescopic cylinders 46 on the plurality of deviation rectifying and straightening assemblies 4 to synchronously extend, so that the inclined cross plate 44 rotates around the sliding plate 43 as the center and becomes horizontal.

[0044] Such as Figure 9As shown, when the bar workpieces 5 transferred from the triangular plate 13 to the multiple stock storage mechanisms 3 are stacked in a staggered manner, the telescopic cylinders three 47 on the multiple deviation rectifying and straightening components 4 are synchronously contracted, driving the sliding plates 43 and the cross plates 44 to move downward. During the downward movement of the cross plates 44, the multiple straightening mechanisms 48 will abut against each of the bar workpieces 5 on the topmost layer. According to the different heights of each bar workpiece 5 on the topmost layer, the return springs 485 on the corresponding straightening mechanisms 48 will be stretched by different lengths, so that the V-shaped wheels 483 on each straightening mechanism 48 will abut against each of the bar workpieces 5 on the topmost layer;

[0045] After that, all the gear-rack linear modules 41 are synchronously controlled to drive the sliding brackets 42 thereon to move left and right reciprocally. During the left and right reciprocating movement of the V-shaped wheels 483, when a certain bar workpiece 5 is bent or staggeredly placed on another bar workpiece 5, the V-shaped wheels 483 will automatically correct and straighten it. At this time, the multiple bar workpieces 5 stacked in a staggered manner will change from the Figure 9 state shown to the Figure 10 state shown, ensuring that all the stacked bar workpieces 5 are parallel to each other.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
