Description
Technical Field
[0001] The utility model relates to the technical field of building material production, and more specifically, to a drawing machine for processing steel bars. Background Art
[0002] The drawing machine for processing steel bars is a professional equipment used to change the shape and size of steel bars through stretching and compression technology. Its core components include the main machine, transmission, straightening, lubrication and control system. During drawing, the steel bar is kept in a straight state by the straightening wheel in the stretching area of the main machine, and then gradually deformed under the action of the tensile force. At the same time, the lubrication system effectively reduces friction and heat to ensure the smooth progress of the drawing process. This mechanical equipment plays an indispensable role in the field of steel processing with its high efficiency and precision, meeting the processing needs of various steel bars and improving production efficiency and product quality. The existing fixed straightening wheel distance drawing machine has obvious limitations. Since the distance of the straightening wheel cannot be adjusted, this machine is usually only suitable for steel bars of a specific diameter. For products of different specifications, the straightening effect is difficult to guarantee, which may affect product quality. In addition, the straightening wheel with a fixed distance cannot adjust the straightening force according to the different requirements of the steel bar material and the drawing process, which limits the operator's fine control of the drawing process, which may lead to reduced production efficiency or unstable product quality. What's worse, when the diameter of the steel rod changes, it may be necessary to replace the entire set of correction wheels or the entire correction mechanism, which undoubtedly increases the maintenance cost of the equipment. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a drawing machine for processing steel bars, which has the advantage of being easy to adjust the distance between the correction wheels.

[0015] The working principle and beneficial effects of the utility model are:
[0016] 1. Compared with the traditional drawing machine, the utility model facilitates the adjustment of the distance between the two straightening wheels through the cooperation between the bidirectional screw and the slider, and can be flexibly adjusted according to the diameter of the bar and the drawing requirements to ensure that the bar is subjected to just the right straightening force when passing through, effectively eliminating its bending or twisting. If the spacing is too close, the straightening force may be too large, increasing the stress of the bar and even causing it to break. If the spacing is too far, the straightening force is insufficient, making it difficult to achieve the ideal straightening effect. In addition, the appropriate spacing can also improve the stability of the bar during the drawing process, reduce vibration and shaking, and improve production efficiency and product quality. At the same time, optimizing the spacing between the straightening wheels also helps to enhance the overall stability and reliability of the drawing machine, and reduce the failure rate and maintenance costs.
[0017] 2. The utility model is combined with the traditional drawing machine. The drawing machine facilitates the movement of the fixed fixture through the cooperation between gear one and gear two, which can stably fix the bar material to prevent displacement and shaking, and ensure processing accuracy and product quality; it can also improve production efficiency, reduce operation time and labor costs, and make the processing process more efficient and convenient. At the same time, the pulling movement method of the fixed fixture effectively reduces processing errors and improves consistency. Its design is flexible and adaptable, and can adapt to bars of different sizes and shapes, thereby improving equipment utilization. Most importantly, the fixed fixture can protect the bar material from damage or scratches and extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] like Figures 1 to 5 As shown, the utility model provides a drawing machine for processing steel bars, comprising a workbench 1, a slide groove 18 is provided inside the workbench 1, a slider 10 is movably installed inside the slide groove 18, a bidirectional screw rod 11 is movably installed inside the slider 10, and the bidirectional screw rod 11 completely penetrates the inside of the workbench 1, and a manual rocker 19 is fixedly installed at one end of the slide groove 18;
[0027] A fixing column 12 is fixedly installed on the top of the slider 10 , a correction wheel 9 is fixedly installed on the top of the fixing column 12 , and a drawing die 2 is fixedly installed on the top of the workbench 1 .
[0028] When the staff is processing the bar, it is necessary to adjust the distance between the two correction wheels 9. By manually holding the rocker 19, the manual rocker 19 drives the bidirectional screw 11 to rotate inside the workbench 1 and the slider 10, so that the two sliders 10 move inside the slide groove 18, and then the two sliders 10 drive the two fixed columns 12 to slowly approach each other, and then the two fixed columns 12 drive the two correction wheels 9 to slowly approach each other until the bar is moved to the appropriate distance for processing, thereby completing the distance adjustment between the two correction wheels 9.
[0029] When processing the bar, it is necessary to adjust the distance between the two correcting wheels 9. By manually holding the rocker 19, the manual rocker 19 drives the bidirectional screw 11 to rotate inside the slider 10, so that the two sliders 10 move inside the slide groove 18, and then the two sliders 10 drive the two support plates 8 to slowly approach each other, and then the two support plates 8 drive the two correcting wheels 9 to slowly approach each other until the bar is moved to a suitable distance for processing. Compared with the traditional drawing machine, the drawing machine facilitates the adjustment of the distance between the two correcting wheels 9 through the cooperation between the bidirectional screw 11 and the slider 10, and can be flexibly adjusted according to the bar diameter and drawing requirements to ensure that the bar is subjected to just the right straightening force when passing through, effectively eliminating its bending or twisting. If the spacing is too close, the straightening force may be too large, increasing the stress of the bar and even causing it to break. If the spacing is too far, the straightening force is insufficient and it is difficult to achieve the ideal straightening effect. In addition, appropriate spacing can also improve the stability of the bar during the drawing process, reduce vibration and shaking, and improve production efficiency and product quality. At the same time, optimizing the spacing of the straightening wheels 9 can also help enhance the overall stability and reliability of the drawing machine and reduce failure rates and maintenance costs.

The steel bars are supported by the two placement racks 5, thereby improving the collection efficiency of the steel bars.
[0040] A support base 27 is fixedly installed between the workbench 1 and the motor 20 , and the interior of the support base 27 is arc-shaped.
