Description

Technical Field

[0001] This utility model relates to the field of steel bar wire drawing technology, and more specifically, to a wire drawing device for cold-rolled ribbed steel bar base material. Background Technology

[0002] Cold-rolled ribbed steel bar base material is a type of steel with a specific chemical composition, mainly used in the production of cold-rolled ribbed steel bars. In existing cold-rolled ribbed steel bar base material production processes, a wire drawing device is required to draw the steel bars. An existing steel bar wire drawing machine (publication number CN111715713B) includes a frame with two mounting brackets fixed on it. A rolling roller assembly and a guide assembly are located on the side wall of the mounting brackets facing each other. The guide assembly guides the drawn steel bars, and the rolling roller assembly rolls the guided steel bars to form transverse and longitudinal ribs. A wire drawing mechanism is located on the outer side wall of the mounting bracket near the guide assembly. The wire drawing mechanism includes a wire drawing die assembly and a wire drawing powder box assembly. The wire drawing die assembly is located between the wire drawing powder box assembly and the mounting brackets. The wire drawing powder box assembly rotates to coat the steel bars with wire drawing powder and then guides the steel bars into the wire drawing die assembly. This invention allows the wire drawing powder box assembly to rotate, resulting in a more uniform distribution of the wire drawing powder within the box assembly, preventing the powder from failing to adhere to the steel bars.

[0003] However, in the above solution, after the wire drawing powder of the steel bar is removed from the wire drawing die assembly, the wire drawing powder adhering to the surface of the steel bar can easily drift into the surrounding working environment, causing the surrounding working environment to be polluted and affecting the cleanliness of the work area. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] like Figures 1-9 As shown, a cold-rolled ribbed steel bar drawing device includes a frame 1, a turntable 2 is provided on one side of the bottom of the frame 1, and a rotating frame 3 is fixedly installed on the rotating end of the turntable 2.

[0033] A collection assembly 4 for collecting steel bars is provided on the other side of the bottom inside the frame 1;

[0034] A perforated mold 6 is fixedly installed in the middle of the bottom of the frame 1 via a bracket 5, and a cleaning component 7 for cleaning steel wire is provided in the middle of the bottom of the frame 1.

[0035] The collecting component 4 includes a stand 401, which is fixedly installed on one side of the bottom of the frame 1. A horizontal shaft 402 is rotatably installed on one side of the stand 401. A rotating roller 403 is detachably and fixedly installed on the shaft of the horizontal shaft 402. A dual-axis motor 404 is fixedly installed on the other side of the stand 401. One end of the horizontal shaft 402 passes through the stand 401 and is fixedly connected to one of the output shaft ends of the dual-axis motor 404.

[0036] The cleaning component 7 includes a positioning frame 701, which is fixedly installed in the bottom middle of the frame 1. A rotating sleeve 702 is rotatably installed inside the positioning frame 701. An installation sleeve 703 is provided inside the rotating sleeve 702. A brush sleeve 704 is fixedly installed inside the installation sleeve 703.

[0037] The mounting sleeve 703 has two limiting plates 705 fixedly installed on its body. The inner wall surface of the rotating sleeve 702 has two limiting grooves 706, and the two limiting plates 705 are respectively inserted and engaged with the corresponding limiting grooves 706.

[0038] The operator starts the dual-axis motor 404, which drives the rotating roller 403 to rotate. The rotating roller 403 winds the steel bar, and the steel bar is subjected to tension. The turntable 2 rotates, and the steel bar is released from the rotating frame 3. The steel bar passes through the hole mold 6, thus completing the wire drawing. After the steel bar is released from the hole mold 6, the operator controls the rotating sleeve 702 to rotate. The wire drawing powder adhering to the surface of the steel bar can be cleaned by the rotating brush sleeve 704, preventing the wire drawing powder adsorbed on the surface of the steel bar from being dispersed into the surrounding environment after the steel bar is released from the hole mold 6, thus avoiding pollution of the working environment.

[0039] In another embodiment of this utility model, threaded holes 8 are provided on the surfaces of the two limiting plates 705 that are far apart from each other.

[0040] The inner walls of the two limiting grooves 706 are each provided with a sliding hole 9 on one side. A bolt 10 is slidably installed in each of the two sliding holes 9, and the two bolts 10 are respectively threaded into the corresponding threaded holes 8.

[0041] Workers can remove bolt 10 so that one end is disengaged from threaded hole 8 and enters sliding hole 9, making it easier to remove mounting sleeve 703 and replace brush sleeve 704 that has been used for a long time.

[0042] In another embodiment of this utility model, a spring rod 11 is provided on one side of the inner wall of each of the two limiting grooves 706.

[0043] By setting the spring rod 11, after the bolt 10 is removed by the operator, the spring rod 11 can push the mounting sleeve 703 to move it out of the rotating sleeve 702, without the need for the operator to remove it manually, thus reducing the workload of the operator.

[0044] In another embodiment of the present invention, a first pulley 12 is sleeved on the other output shaft end of the dual-axis motor 404;

[0045] A first bevel gear 13 is fitted on one side of the sleeve body of the rotating sleeve 702. A connecting frame 14 is fixedly installed on one side of the bottom inside the frame 1.

[0046] A second bevel gear 18 is fitted on the other side of the connecting rod 15, and the second bevel gear 18 meshes with the first bevel gear 13.

[0047] When the rotating roller 403 rotates, the other output end of the dual-shaft motor 404 drives the first pulley 12 to rotate. Under the transmission action of the belt 17, the second pulley 16 drives the connecting rod 15 and the second bevel gear 18 to rotate. Under the meshing action of the second bevel gear 18 and the first bevel gear 13, the rotating sleeve 702 rotates.

[0048] In another embodiment of this utility model, an electric guide rail 19 is provided on the other side of the bottom of the frame 1. A limit frame 20 is fixedly installed at the moving end of the electric guide rail 19, and two positioning wheels 21 are rotatably installed inside the limit frame 20.

[0049] By setting positioning wheels 21, deviations are avoided during the transportation of steel bars. Workers activate the electric guide rail 19 to make the positioning wheels 21 move back and forth, so that the positioning wheels 21 are evenly wrapped around the body of the rotating roller 403.

[0050] Working principle of a cold-rolled ribbed steel bar drawing device:

[0051] In use, the operator starts the dual-axis motor 404, which drives the rotating roller 403 to rotate. The rotating roller 403 winds the steel bar, and the steel bar is subjected to tension. The turntable 2 rotates, and the steel bar is separated from the rotating frame 3. The steel bar passes through the hole mold 6, thus completing the wire drawing. After the steel bar is separated from the hole mold 6, the operator controls the rotating sleeve 702 to rotate. The wire drawing powder adhering to the surface of the steel bar can be cleaned by the rotating brush sleeve 704, preventing the wire drawing powder adsorbed on the surface of the steel bar from being scattered into the surrounding environment after it is separated from the hole mold 6, thus avoiding pollution of the working environment.
