Description

Technical Field

[0001] The invention relates to a device and a method for automatically feeding round steel into a cold-sheared hole groove, belonging to the technical field of bar production in the metallurgical industry. Background Art

[0002] During the production process of bar round steel, the double-length round steel on the cooling bed is transported to the cooling bed alignment roller under the action of the cooling bed walking beam, and the double-length round steel is aligned at one end of the double-length round steel at the head baffle on the alignment roller. The aligned double-length round steel continues to be discharged from the cooling bed moving teeth to the cooling bed unloading translation chain one by one under the action of the cooling bed walking beam. According to the shearing number requirements allowed by the cold shearing equipment, after the double-length round steel on the unloading translation chain is collected enough, the double-length round steel in rows is translated to the roller before the cold shearing in the "lifting-translation-descent-reset" cycle on the cooling bed unloading flat support.

[0003] Cold shear is an important equipment for cutting double-length round steel into fixed-length round steel. The cold shear is equipped with upper and lower shear blades with hole grooves. When producing round steel of different specifications, the hole groove shear blade corresponding to the product specifications is used, and the upper shear blade is driven by the transmission side to complete the cutting and cutting operation. The existing shearing technology method is: the rows of double-length round steels before cold shearing are transported to the cold shear cover plate with flow grooves before cold shearing under the action of the cold shear front roller, and the cold shear front roller is stopped. Due to the position deviation between the rows of double-length round steels and the cold shear cover plate flow groove, it is necessary to manually use tools to adjust the spacing of the rows of round steels to be consistent with the cold shear cover plate flow groove, and continue to transport the double-length round steels. If the round steels do not all enter the cold shear cover plate flow groove, it is necessary to reverse the cold shear front roller, readjust the spacing of the round steels to be consistent with the cold shear cover plate flow groove, and then repeat the operation until the rows of double-length round steels all enter the cold shear cover plate flow groove, so that the rows of round steels can pass through the cold shear cover plate flow groove and enter the cold shear blade hole groove for fixed-length shearing operation. This process is time-consuming, requires manual intervention, and the groove needs to be operated again after each group of steel is sheared, resulting in a low cold shearing operation rate, affecting the production rhythm and the control of the shearing temperature of the steel support. Summary of the invention

[0004] The purpose of the present invention is to provide a device and method for automatically feeding round steel into a cold shear hole groove, which can automatically feed the cold shear blade hole groove to perform a fixed-length shearing operation and solve the problems existing in the background technology.

[0005] The technical solution of the present invention is: A device capable of automatically feeding round steel into a cold shear hole groove is provided between a cooling bed and a cold shear, and comprises a positioning plate, an extended cover plate chute and a cold shear cover plate chute which are arranged in sequence according to the running direction of the round steel, wherein the positioning plate is fixed on a cooling bed unloading flat support, and a positioning groove which matches the cold shear hole groove is provided on the positioning plate; the extended cover plate chute and the cold shear cover plate chute both comprise a bottom plate, a partition plate and a through groove, a plurality of partition plates are fixed on the bottom plate, a round steel chute is formed between two adjacent partition plates, the size of the round steel chute matches the cold shear hole groove, and a through groove which matches the roller is also provided on the bottom plate; a thickened partition plate welded to the partition plate is also provided on the outlet side of the cold shear cover plate chute, a cold shear hole feeding groove is formed between two adjacent thickened partition plates, and the size of the cold shear hole feeding groove matches the diameter of the round steel.

[0006] The positioning grooves, round steel chutes and cold shear hole-shaped feeding grooves on the positioning plate correspond to each other one by one, and their number is the same as the number of cut-length round steels.

[0007] The bottom plate on the inlet side of the round steel chute is inclined downward, and the partition plate on the inlet side of the round steel chute is in an arc shape.

[0008] The bottom plate on the inlet side of the round steel chute is tilted downward by 18°.

[0009] The inlet and outlet of the cold shear hole type feeding trough are both trumpet-shaped.

[0010] The bottom plates in the extended cover plate chute and the cold shear cover plate chute are both rectangular steel plates, and mounting plates are respectively provided on both sides of the bottom plates.

[0011] A method for automatically feeding round steel into a cold shear hole groove adopts the device for automatically feeding round steel into a cold shear hole groove as defined above, and rows of multiple-length round steels enter the extended cover plate flow groove through the positioning groove on the positioning plate, and under the action of the conveying roller before cold shearing, they pass through the cold shear cover plate flow groove and enter the cold shear blade hole groove, and the fixed-length shearing is carried out under the condition that the spacing between the rows of multiple-length round steels and the spacing between the cold shear blade hole grooves are consistent.

[0012] The beneficial effect of the present invention is that the rows of double-length round steels no longer require manual intervention from the time of unloading from the cooling bed to the time of entering the cold shear hole groove, and the spacing between the rows of double-length round steels can be kept consistent with the spacing of the cold shear blade hole groove, and the cold shear blade hole groove is automatically fed for fixed-length shearing operation. This reduces manpower and labor, saves time and effort, and at the same time improves the shearing operation rate of the cold shear, improves the rolling rhythm, and improves the rolling line capacity.

DETAILED DESCRIPTION

[0014] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0015] Refer to the attached Figure 1-7 , a device for automatically feeding round steel into a cold shearing hole groove, the device is arranged between a cooling bed and a cold shear, and comprises a positioning plate 1, an extended cover plate chute 6 and a cold shearing cover plate chute 10 arranged in sequence according to the running direction of the round steel, the positioning plate 1 is fixed on a cooling bed unloading flat support 4, and a positioning groove 2 matching the cold shearing hole groove is provided on the positioning plate 1; the extended cover plate chute 6 and the cold shearing cover plate chute 10 both comprise a bottom plate 6, a partition plate 7 and a through groove 8, a plurality of partition plates 7 are fixed on the bottom plate 6, a round steel chute is formed between two adjacent partition plates 7, the size of the round steel chute matches the cold shearing hole groove, and a through groove 8 matching the roller is further provided on the bottom plate 6; a thickened partition plate 11 welded to the partition plate 7 is further provided on the outlet side of the cold shearing cover plate chute 10, a cold shearing hole feeding groove is formed between two adjacent thickened partition plates 11, and the size of the cold shearing hole feeding groove matches the diameter of the round steel.

[0016] In this embodiment, refer to the attached Figure 1-7 The device is arranged between the cooling bed and the cold shear, and comprises a positioning plate 1, an extended cover plate chute 6 and a cold shear cover plate chute 10 arranged in sequence according to the running direction of the round steel, wherein: Refer to the attached Figure 1 , 2 The positioning plate 1 is a rectangular steel plate, and one long side of the steel plate is provided with equally spaced semicircular positioning grooves 2 that are consistent with the spacing of the cold shear blade hole grooves. The intervals between the slot holes are heightened and have arc transitions. A long strip through hole is opened on the steel plate as a mounting hole 3. The function of the long strip through hole is to allow the position of the positioning plate 1 installed on the cooling bed unloading flat drag 4 to be slightly adjusted.

[0017] The positioning plate 1 is installed on the cooling bed unloading flat drag 4. The lowest point of the semicircular hole groove of the positioning plate 1 is on the same horizontal line as the upper surface of the cooling bed unloading flat drag 4. The positioning plate 1 prevents the round steel from rolling but does not bear weight.

[0018] The cooling bed electrical PLC control sets the translation stroke of the cooling bed unloading translation chain. Each time the cooling bed unloads a double-length round steel, the cooling bed unloading translation chain runs a translation stroke, and the distance of a translation stroke is consistent with the spacing of the cold shear blade hole grooves. On the first unloading flat drag at the cooling bed outlet, install the round steel anti-roll positioning plate. After the double-length round steel on the cooling bed unloading translation chain is collected enough, the cooling bed unloading flat drag is lifted, and the double-length round steel heads fall into the slots of the round steel anti-roll positioning plate. The spacing of the double-length round steel heads and the spacing of the cold shear blade hole grooves can be kept consistent. The cooling bed unloading flat drag is translated to translate the rows of double-length round steels to the rollers in front of the cold shear.

[0019] Refer to the attached Figure 3 , 4 The extended cover plate flow channel 5 is welded from steel plates and includes a bottom plate 6 and a partition plate 7 welded on the bottom plate. The spacing between the partition plates 7 is consistent with the spacing between the cold shear blade slots. The bottom plate 6 on the inlet side of the flow channel is tilted downward by 18°, and the partition plate 7 is in an arc shape, with the arc-shaped part being narrow at the top and wide at the bottom. The bottom plate 6 is provided with a through groove 8 perpendicular to the partition plate 7, and the through groove 8 is used to be installed on the roller table before the cold shear. The bottom plate 1 is symmetrically welded with mounting fixing plates 8 on both sides.

[0020] The extended cover plate flow channel 5 is installed on the cooling bed outlet conveying roller, with the flow channel inlet side facing the cooling bed outlet direction. After installation, the length of the flow channel inlet side is 150mm longer than the horizontal reference line of the working surface of the flush baffle on the cooling bed alignment roller.

[0021] Refer to the attached Figure 5 , 6 The cold shear cover plate chute 9 has the same structure as the extended cover plate chute 5, except that a nearly diamond-shaped thickened partition 10 is welded on the outlet side of the cold shear cover plate chute 9, and the spacing between the thickened partitions 10 is smaller than the spacing between the partitions. The thickened partition 10 plays a positioning role for the round steel, and there is no bottom plate under the thickened partition 10. The inlet side of the cold shear cover plate chute 9 is adjacent to the outlet of the extended cover plate chute 5, and the outlet of the cold shear cover plate chute 9 faces the cold shear blade.

[0022] Refer to the attached Figure 7 The center lines of the positioning groove 2 on the positioning plate 1, the extended cover plate chute 6 and the cold shear cover plate chute 10 are in a straight line with the center line of the cold shear blade slot hole, and each chute partition hole can only accommodate one double-length round steel. The heads of the rows of double-length round steels fall into the extended cover plate chute 5 through the positioning groove 2 on the positioning plate 1. Under the action of the conveying roller before cold shearing, the rows of double-length round steels pass through the cold shear cover plate chute 9 and enter the cold shear blade hole groove, so that the spacing of the rows of double-length round steels is consistent with the spacing of the cold shear blade hole groove. The fixed-length shearing operation is performed, and manual intervention is no longer required, which improves the shearing operation rate of cold shearing.
