Description

Technical Field

[0001] This utility model relates to a device that enables automatic feeding of round steel bars into cold-sheared slots, belonging to the field of bar production technology in the metallurgical industry. Background Technology

[0002] In the production of bar and round steel, the multiple-length round steel bars on the cooling bed are transported to the cooling bed alignment roller conveyor under the action of the cooling bed walking beam. The multiple-length round steel bars are aligned at one end at the alignment baffle on the alignment roller conveyor. After alignment, the multiple-length round steel bars continue to be unloaded one by one from the cooling bed moving teeth to the cooling bed unloading translation chain under the action of the cooling bed walking beam. According to the shearing requirements allowed by the cold shearing equipment, after enough multiple-length round steel bars are collected on the unloading translation chain, the multiple-length round steel bars are moved in rows to the cold shearing pre-shear roller conveyor under the "lifting-translating-lowering-resetting" cycle on the cooling bed unloading flat support.

[0003] Cold shears are important equipment for cutting multiple-length round steel into fixed-length round steel. Cold shears are equipped with upper and lower shear blades, and the shear blades have perforated grooves. When producing round steel of different specifications, the shear blade with the perforated groove corresponding to the product specifications is used. The upper shear blade is driven by the transmission side to complete the cutting to fixed length operation. The existing shearing technology involves: rows of multiple-length round steel bars being transported to the cold shear cover plate with a flow channel by a roller conveyor before cold shearing. The roller conveyor then stops. Due to a misalignment between the rows of round steel bars and the flow channel, manual adjustment of the spacing between the bars is required. If not all the steel bars enter the flow channel, the roller conveyor needs to be reversed, and the spacing readjusted. This process is repeated until all the round steel bars are inside the flow channel, allowing them to pass through the flow channel and enter the shear blade slot for fixed-length shearing. This process is time-consuming, requires manual intervention, and necessitates re-adjusting the slot after each set of steel is sheared, resulting in a low cold shearing efficiency, impacting production rhythm and the control of steel shearing temperature. Utility Model Content

[0004] The purpose of this invention is to provide a device that can automatically feed round steel into the cold shearing slot, enabling it to automatically feed into the cold shearing blade slot for fixed-length shearing operations, thus solving the problems existing in the background technology.

[0005] The technical solution of this utility model is:

[0006] A device for automatically feeding round steel bars into a cold shear chute is provided. The device is positioned between a cooling bed and a cold shear. Following the direction of the round steel bar's movement, it comprises a positioning plate, an extension cover chute, and a cold shear cover chute arranged sequentially. The positioning plate is fixed to the unloading support of the cooling bed and has a positioning groove that mates with the cold shear chute. Both the extension cover chute and the cold shear cover chute include a base plate, partitions, and a through groove. Several partitions are fixed to the base plate, forming a round steel chute between adjacent partitions. The size of the round steel chute matches the cold shear chute. The base plate also has a through groove that mates with a roller conveyor. A thickened partition welded to the partitions is also provided on the outlet side of the cold shear cover chute. A cold shear feeding chute is formed between adjacent thickened partitions, and its size matches the diameter of the round steel bar.

[0007] The positioning slots, round steel chutes, and cold shearing feed slots on the positioning plate correspond one-to-one, and their number is the same as the number of cut round steel bars.

[0008] The bottom plate on the inlet side of the round steel chute slopes downward, and the partition on the inlet side of the round steel chute is arc-shaped.

[0009] The bottom plate on the inlet side of the round steel chute is inclined downward at 18°.

[0010] The inlet and outlet of the cold shearing feed trough are both funnel-shaped.

[0011] The bottom plates of both the extended cover plate chute and the cold shear cover plate chute are rectangular steel plates, and mounting plates are provided on both sides of the bottom plate.

[0012] The beneficial effects of this invention are: from the moment the rows of multiple-length round steel bars are unloaded from the cooling bed until they enter the cold shear slots, no manual intervention is required. This ensures that the spacing between the rows of multiple-length round steel bars matches the spacing of the cold shear blade slots, allowing for automatic feeding into the cold shear blade slots for fixed-length shearing. This reduces manpower and labor, saves time and effort, and simultaneously increases the shearing rate of the cold shear, improves the rolling rhythm, and increases the production capacity of the rolling line.

[0021] The present invention will be further described below with reference to the accompanying drawings and examples.

[0022] See attached document Figure 1-7 A device for automatically feeding round steel into a cold shear chute is disclosed. The device is positioned between a cooling bed and a cold shear. Following the direction of the round steel's movement, it comprises a positioning plate 1, an extension cover chute 5, and a cold shear cover chute 10 arranged sequentially. The positioning plate 1 is fixed to the unloading support 4 of the cooling bed and has a positioning groove 2 that mates with the cold shear chute. Both the extension cover chute 5 and the cold shear cover chute 10 include a base plate 6, partitions 7, and through grooves 8. Several partitions 7 are fixed to the base plate 6, and adjacent partitions 7 form a round steel chute. The size of the round steel chute matches the cold shear chute. The base plate 6 also has through grooves 8 that mate with a roller conveyor. A thickened partition 11, welded to the partitions 7, is located on the outlet side of the cold shear cover chute 10. Adjacent thickened partitions 11 form a cold shear chute feeding groove, the size of which matches the diameter of the round steel.

[0023] In this embodiment, refer to the appendix Figure 1-7 The device is installed between the cooling bed and the cold shear. Following the direction of the round steel's movement, it comprises a positioning plate 1, an extension cover chute 5, and a cold shear cover chute 10, arranged sequentially.

[0024] See attached document Figure 1 , 2 The positioning plate 1 is a rectangular steel plate. On one long side of the steel plate, there are semi-circular positioning grooves 2 with equal spacing, which are consistent with the spacing of the cold shear blade slots. The spacing between the slots is raised and has a rounded transition. There are long strip-shaped through holes on the steel plate as mounting holes 3. The function of the long strip-shaped through holes is to allow the position of the positioning plate 1 on the unloading flat drag 4 of the cooling bed to be slightly adjusted.

[0025] Positioning plate 1 is installed on the unloading flatbed trailer 4 of the cooling bed. The lowest point of the semi-circular groove of positioning plate 1 is on the same horizontal line as the upper surface of the unloading flatbed trailer 4 of the cooling bed. Positioning plate 1 is used to prevent the round steel from rolling and does not bear weight.

[0026] The translation stroke of the cooling bed unloading translation chain is set by the PLC control of the cooling bed electrical system. Each time a multiple-length round steel bar is unloaded from the cooling bed, the translation chain travels one translation stroke. The distance of one translation stroke is consistent with the spacing of the slots in the cold shear blades. A round steel anti-roll positioning plate is installed on the first unloading trailer at the cooling bed exit. After enough multiple-length round steel bars have been collected on the cooling bed unloading translation chain, the trailer is lifted, and the heads of the multiple-length round steel bars fall into the slots of the anti-roll positioning plate. The spacing between the heads of the multiple-length round steel bars can be kept consistent with the spacing of the slots in the cold shear blades. The cooling bed unloading trailer then translates, moving the rows of multiple-length round steel bars to the cold shear pre-shear roller conveyor.

[0027] See attached document Figure 3 , 4 The extended cover plate flow channel 5 is welded from steel plates and includes a base plate 6 and partitions 7 welded to the base plate. The spacing between the partitions 7 is consistent with the spacing of the cold shear blade slots. The base plate 6 on the inlet side of the flow channel is inclined downward at 18°, and the partitions 7 are arc-shaped, with the arc-shaped part being narrower at the top and wider at the bottom. The base plate 6 has a through groove 8 perpendicular to the partitions 7, which is used for installation on the cold shear front roller conveyor. Mounting fixing plates 8 are welded symmetrically on both sides of the base plate 1.

[0028] The extended cover plate flow channel 5 is installed on the cooling bed outlet conveyor roller. The inlet side of the flow channel faces the cooling bed outlet direction. After installation, the length of the inlet side of the flow channel is 150mm longer than the horizontal reference line of the working surface of the baffle on the cooling bed alignment roller.

[0029] See attached document Figure 5 , 6 The cold shear chute 9 has the same structure as the extended chute 5, except that an approximately rhomboid thickened baffle 10 is welded to the outlet side of the cold shear chute 9. The spacing between the thickened baffles 10 is smaller than the spacing between the baffles themselves. The thickened baffles 10 serve to position the round steel bars, and there is no bottom plate under the thickened baffles 10. The inlet side of the cold shear chute 9 is adjacent to the outlet of the extended chute 5, and the outlet of the cold shear chute 9 faces the cold shear blade.

[0030] See attached document Figure 7 The center lines of the positioning groove 2, the extension cover plate chute 5, and the cold shear cover plate chute 10 on the positioning plate 1 are aligned with the center line of the cold shear blade slot. Each flow channel partition hole can only accommodate one multiple-length round steel bar. The heads of rows of multiple-length round steel bars fall into the extension cover plate flow channel 5 through the positioning groove 2 on the positioning plate 1. Under the action of the conveying rollers before cold shearing, the rows of multiple-length round steel bars pass through the cold shear cover plate flow channel 9 and enter the cold shear blade slot. This ensures that the spacing between rows of multiple-length round steel bars is consistent with the spacing between the cold shear blade slots, allowing for fixed-length shearing without manual intervention and improving the cold shearing efficiency.
