Description

Technical Field

[0001] The present application relates to the technical field of steel section production, and in particular to a feeding device for cold-drawn I-beam production. Background Art

[0002] Steel sections are strip steels with certain cross-sectional shapes and sizes, and are one of the four major types of steel. According to the cross-sectional shape of the steel sections, they can be divided into simple cross-sectional steel sections and complex cross-sectional steel sections. I-beams are one type of complex cross-sectional steel sections. Because steel sections have the advantages of high strength, low weight, and ease of construction, they are widely used in construction, bridges, machinery manufacturing, shipbuilding and other fields. Cold drawing is a common metal processing process. During the cold drawing process, the metal billet is subjected to tensile force at room temperature to pass through a die or a drawing die to obtain the desired shape, size and mechanical properties. The cold drawing process can improve the mechanical properties, surface quality and dimensional accuracy of metal materials, improve the strength and hardness of the material, and reduce the cross-sectional area of ​​the material.

[0003] At present, when cold drawing I-beams, it is necessary to manually place the I-beam billet on a workbench or conveyor belt to facilitate the subsequent cold drawing of the I-beam. However, this operation method takes a long time, is inefficient, and has a high labor intensity for workers, which is not convenient for the continuous and rapid production of I-beams. Utility Model Content

[0004] In order to improve the continuous feeding of steel billets and reduce the labor intensity of workers, the present application provides a feeding device for the production of cold-drawn I-beams.

[0005] The present application provides a feeding device for cold-drawn I-beam production using the following technical solution:

[0006] A feeding device for the production of cold-drawn I-beams, comprising a storage box, a feeding assembly, a bottom plate and a conveyor belt, wherein the bottom end of the storage box is open, the inner cross-section of the storage box corresponds to the shape of the steel billet, the bottom plate is arranged below the storage box, the feeding assembly comprises a feeding plate, the feeding plate is arranged between the storage box and the bottom plate and slidably fits with the two, the feeding plate is provided with a feeding slot corresponding to the bottom end opening of the storage box, the bottom plate is provided with a driving member for driving the feeding plate to move, and one end of the conveyor belt is arranged below the bottom plate.

[0007] By adopting the above technical solution, the unloading plate moves between the storage box and the bottom plate under the drive of the driving member. The I-beams are stacked one by one in the storage box. When the unloading plate moves to the point where the unloading slot corresponds to the discharge end of the storage box, the steel billet at the bottom of the storage box falls into the unloading slot. The unloading plate is pushed toward the conveyor belt by the driving member. When the unloading slot moves out of the edge of the bottom plate, the steel billet in the unloading slot falls onto the conveyor belt for transmission. Through the mutual cooperation of the storage box, unloading assembly, driving member, bottom plate and conveyor belt, the periodic automatic loading of steel billets is realized, which has the effect of improving the continuous loading of steel billets and reducing the labor intensity of workers.

[0008] Optionally, the driving member includes a linkage rod group, the linkage rod group includes a driving rod and a connecting rod, one end of the connecting rod is rotatably connected to the side of the unloading plate, and the other end of the connecting rod is rotatably connected to the driving rod, a driving source is provided on the bottom plate, the driving source is rotatably connected to one end of the driving rod away from the connecting rod, the driving rod and the rotation plane of the connecting rod are arranged coplanar, and when the driving rod is rotated to a certain angle, the unloading groove on the unloading plate is connected to the bottom end opening of the storage box.

[0009] By adopting the above technical solution, the driving rod rotates under the action of the driving source, and the linkage rod moves with the driving rod. The blanking plate moves back and forth periodically under the storage box under the action of the linkage rod. The setting of the linkage rod group realizes the periodic reciprocating drive of the blanking plate.

[0010] Optionally, an adjustment assembly is provided on the material storage box, the adjustment assembly includes an adjustment plate, an adjustment screw and a guide rod, the adjustment plate is vertically arranged in the material storage box, the shape of the adjustment plate corresponds to the shape of the inner walls on both sides of the width direction of the material storage box, the adjusting screw is horizontally threadedly connected to the vertical side walls in the length direction of the material storage box, one end of the adjusting screw extends into the material storage box and is rotatably connected to the adjustment plate, the guide rod passes through the side wall of the material storage box and is slidably connected thereto, the guide rod is arranged parallel to the adjusting screw, and one end of the guide rod is connected to the adjustment plate.

[0011] By adopting the above technical solution, for billets of different widths, the adjusting screw is screwed, and the adjusting plate moves along the width direction of the storage box under the drive of the adjusting screw and the guidance of the guide rod until the spacing between the adjusting plate and the vertical inside of the storage box matches the width of the billet. The setting of the adjusting assembly enables the storage box to adapt to billets of different widths, avoids the billets shaking and overlapping in the storage box during the blanking process, and improves the stability of the blanking process.

[0012] Optionally, an installation frame is provided above the base plate, and two storage boxes are provided. A connecting rod is connected between the two storage boxes.

[0013] By adopting the above technical solution, when loading, the discharge end of one of the storage boxes corresponds to the periodic position of the unloading slot on the unloading plate for loading. When there is no billet in the storage box, the driving cylinder is started to push the two storage boxes at the same time, and the other storage box with billets is moved to the position of the empty storage box under the action of the driving cylinder for uninterrupted loading. At this time, the operator can place billets in the empty storage box to cope with subsequent loading. The arrangement of the two storage boxes and the driving cylinder realizes uninterrupted loading of billets, which helps to improve the loading efficiency of the device.

[0015] By adopting the above technical solution, the abutting roller abuts against both ends of the billet in the length direction, which reduces the sliding friction force on the billet during the blanking process and helps the blanking process to proceed more smoothly.

[0017] By adopting the above technical solution, when there are I-beam billets in the storage box for unloading, the billets are between the sensor transmitting end and the sensor receiving end, and the sensor receiving end cannot receive the signal from the sensor transmitting end. When there are no billets in the storage box, there is no shielding between the sensor receiving end and the sensor receiving end, the sensor receiving end receives the signal emitted from the sensor transmitting end, the driving cylinder receives the signal and starts, and the position of the storage box is adjusted in time.

[0035] Reference Figure 1 An extension plate 13 is vertically fixedly connected to the bottom surface of the bottom plate 2 near one end of the conveyor belt 3, and a material discharge inclined plate 14 is fixedly connected to the bottom edge of the extension plate 13. The material discharge inclined plate 14 is inclined and extends to the top surface of the conveyor belt 3.

[0036] Reference Figure 1-3Before discharging, the I-beam billets are stacked one by one in the storage box 1. For billets of different widths, the inner cross-sectional width of the storage box 1 needs to be adjusted. The adjusting screw 61 is screwed, and the adjusting plate 63 moves along the width direction of the storage box 1 under the driving of the adjusting screw 61 and the guiding action of the guide rod 62. The setting of the scale line 64 facilitates the precise adjustment of the position of the adjusting plate 63. The setting of the adjusting assembly 6 enables the storage box 1 to adapt to billets of different widths, and avoids the billets from shaking and overlapping in the inner cavity of the storage box 1 during the blanking process.

[0037] Reference Figure 1 and Figure 3 After the adjustment of the storage box 1 is completed, the unloading operation begins. The unloading motor 51 starts to drive the driving gear 54 to rotate, and the driven gear 55 and the linkage rod 53 rotate under the drive of the driving gear 54. The linkage rod 53 and the driving rod 56 rotate along with the driven gear 55, and the linkage rod 57 moves under the drive of the driving rod 56. The unloading plate 52 periodically reciprocates between the storage box 1 and the bottom plate 2 under the action of the linkage rod 57 group. When the unloading plate 52 moves to the position where the unloading slot 521 corresponds to the discharge end of one of the storage boxes 1, the bottom billet falls into the unloading slot 521 under the action of gravity. The unloading plate 52 is pushed toward the conveyor belt 3 under the action of the linkage rod group. When the unloading slot 521 moves out of the edge of the bottom plate 2, the billet in the unloading slot 521 falls onto the unloading inclined plate 14 under the action of gravity and slides along the inclined surface to the conveyor belt 3 for conveyance. The device repeats the above operation to realize the periodic automatic loading of the billet, reduce the labor intensity of the workers, and improve the loading efficiency of the billet. The setting of the unloading inclined plate 14 prevents the billet from falling directly onto the conveyor belt 3 and causing damage to the conveyor belt 3 and the billet. The abutting roller 10 abuts against the end of the billet, so that the billet can be unloaded more smoothly.

[0038] Reference Figure 3 and Figure 4 When there is an I-beam billet in the storage box 1 used for unloading, the billet at the bottom is blocked between the sensor transmitting end 11 and the sensor receiving end 12, and the sensor receiving end 12 cannot receive the signal emitted by the sensor transmitting end 11. When there is no billet in the storage box 1, the sensor receiving end 12 receives the signal emitted by the sensor transmitting end 11, and the control system receives the signal and starts the driving cylinder 9, which drives the cylinder 9 to push another storage box 1 containing I-beam billets to the position of the empty storage box 1 for unloading. At this time, the operator can fill the empty storage box 1, realizing the uninterrupted loading process and further improving the loading efficiency of the billets. The setting of the sensor transmitting end 11 and the sensor receiving end 12 detects in real time whether there are still I-beam billets in the storage box 1, which is convenient for timely filling and shifting of the storage box 1.

[0039] The implementation principle of a feeding device for cold-drawn I-beam production in the embodiment of the present application is as follows: before discharging, the I-beam billets are accumulated one by one in the storage box 1, and for billets of different widths, the inner cross-sectional width of the storage box 1 is adjusted using the adjustment component 6. After the adjustment of the storage box 1 is completed, the unloading operation begins. Under the action of the linkage rod 57 group, the unloading plate 52 periodically reciprocates between the storage box 1 and the bottom plate 2. When the unloading plate 52 moves to the unloading slot 521 corresponding to the position of the unloading end, a billet falls into the unloading slot 521. The unloading plate 52 is pushed toward the direction of the conveyor belt 3, and the billet in the unloading slot 521 falls onto the unloading inclined plate 14 and onto the conveyor belt 3. The device repeats the above operation, realizing the periodic automatic loading of the billets, reducing the labor intensity of the workers, and improving the loading efficiency of the billets.

[0040] When there is no billet in the storage box 1, the driving cylinder 9 pushes another storage box 1 filled with I-beam billets to the position of the empty storage box 1 for unloading. At this time, the operator can fill the empty storage box 1, thereby realizing the uninterrupted loading process.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
