Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically a telescopic steel bar straightening protective device. Background Technology

[0002] Wire rod is a type of round steel with a small diameter. It is supplied in coils. Common sizes on construction sites are 6, 8, 10, and 12 mm in diameter, mostly made of low-carbon steel. Before use, wire rod needs to be straightened and cut using a steel bar straightening machine. At the same time, the machine removes oxide scale and rust. Through repeated bending and stretching, its strength is improved to a certain extent.

[0003] like Figure 5 As shown, existing rebar straightening machines lack protective features at their feed inlet. When straightening coiled rebar, the circular coils of the rebar will rotate as the straightening machine pulls them. At this time, the straightening operator and passersby are easily injured by the rotating rebar coils. Therefore, we propose a telescopic rebar straightening protective device. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 In this embodiment of the utility model, a telescopic steel bar straightening protective device includes an inner protective cover 1 and a first square frame 2. The inner protective cover 1 is a truncated square pyramid with openings at both ends. The large-diameter end of the inner protective cover 1 is slidably installed inside the outer protective cover 7. An auxiliary support mechanism 11 is installed at the bottom of the small-diameter end of the inner protective cover 1. A plurality of second support seats 16 are fixedly installed at the bottom of the end of the outer protective cover 7 away from the auxiliary support mechanism 11.

[0022] By adopting the above-mentioned solution, this utility model allows for the following steps: When using the device, the inner protective cover 1 is pulled out a certain distance from the outer protective cover 7. The smaller diameter end of the inner protective cover 1 is then placed at the feed inlet of the rebar straightening machine. One end of the coiled rebar is then inserted into the rebar straightening machine through the outer and inner protective covers, thus straightening the rebar. During the straightening process, the inner and outer protective covers 1 and 7 restrict the rotation amplitude and range of motion of the coiled rebar, effectively protecting workers. The protective device composed of the inner and outer protective covers 1 not only allows for easy adjustment of the overall length of the device according to needs, but also allows the inner protective cover 1 to be completely retracted into the outer protective cover 7 when not in use, reducing the device's footprint and resulting in good performance.

[0023] Specific combination Figure 1 , Figure 2 and Figure 4 In one embodiment of the present invention, the inner protective cover 1 includes a first square frame 2 and a second square frame 3.
