Description

Technical Field

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

[0002] In the construction of buildings, bridges and other engineering projects, the circular processing of steel reinforcement components (such as pile foundation stirrups, tunnel support rings, etc.) is a common requirement.

[0003] In traditional processes, operators typically use manual bending equipment or general-purpose rebar bending machines to complete such tasks. However, in practical applications, the following technical bottlenecks exist: ordinary bending machines rely on manual experience to control the bending arc and lack radial positioning references, resulting in problems such as misalignment of the rebar ends and excessive closing gaps after rounding. This makes it difficult to meet the engineering standard requirements for high-precision ring components (such as diameter tolerance ±2mm). Therefore, this utility model provides a rebar shaping device. Utility Model Content

[0004] To address the problems of traditional steel bar bending processes, which rely on manual experience to control the bending arc and lack radial positioning references, leading to misalignment of the steel bar ends and excessive closing gaps after rounding, making it difficult to meet the engineering standard requirements for high-precision ring components (such as diameter tolerance ±2mm), this utility model provides a steel bar shaping device.

[0033] Please refer to the attached document. Figure 1 - Figure 5 This application illustrates a rebar shaping device for shaping (coiling) rebars. It includes a bending machine 1 (GW-40A model), a large turntable 2 fixedly mounted at the output end of the bending machine 1, which drives the turntable 2 to rotate. Several ring-shaped fixing rods 3 are fixedly mounted on the top of the turntable 2 near its outer edge. Limiting rods 4 are fixedly mounted on the top of the turntable 2 outside the ring-shaped fixing rods 3, forming a clamping area between the limiting rods 4 and the fixing rods 3. The head of the rebar is clamped within this clamping area. A small turntable 5 is rotatably mounted on the top of the turntable 2 inside the ring-shaped fixing rods 3. A cutting machine 6, which can be a GQ40 model, is slidably mounted on the small turntable 5 and used to cut the shaped rebar.

[0034] A lever 7 was also designed, which is fixedly installed on one side of the large turntable 2. It is used to stabilize the steel bars to be shaped that have not entered the area of ​​the large turntable 2. Compared with the traditional manual force control, its operation is more convenient and safer.

[0035] like Figure 1 As shown, when in use, the end of the steel bar is inserted into the clamping area formed between the limiting rod 4 and the fixing rod 3, and the steel bar is pressed against the lever 7. The bending machine 1 drives the large turntable 2 to rotate. The large turntable 2 moves the steel bar and makes the steel bar wrap around the outside of the fixed rod 3 which is distributed in a ring. After the large turntable 2 rotates once, the cutting machine 6 is operated to cut the steel bar.

[0036] In one embodiment, the support frame 7 includes: a column 704, a support member, a sleeve 705, a U-shaped frame 706, and a horizontal column 707.

[0037] Three sets of support members are fixedly connected to the side of the column 704. The three sets of support members are distributed in a triangle, and the bottom end of the support members is fixedly installed to the ground. The sleeve 705 is rotatably installed on the column 704. The reinforcing bar rests against the outside of the sleeve 705. The sleeve 705 can rotate with the movement of the reinforcing bar, so that the wear is uniform and the service life is longer. The U-shaped frame 706 is inverted downwards, and the first column of the U-shaped frame 706 is rotatably connected to the column 704. The second column of the U-shaped frame 706 is parallel and spaced apart from the column 704. A horizontal column 707 is fixedly connected to the side of the second column of the U-shaped frame 706. The horizontal column 707 restricts the upward movement of the reinforcing bar and prevents the reinforcing bar from moving upwards and jumping out of the range of the limiting rod 4 (the limiting rod 4 is generally relatively short).

[0038] Generally, the three sets of support components are arranged in a triangle and are located on one side of the column 704, so that the other side of the column 704 is available for operators to work on.

[0039] In one embodiment, the support includes a first bracket 701, a second bracket 702, and a foot 703.

[0040] The bottom end of the first bracket 701 intersects with the bottom end of the second bracket 702, and the bottom ends of the first bracket 701 and the second bracket 702 are fixedly connected to the foot 703. The top ends of the first bracket 701 and the second bracket 702 are both fixedly connected to the column 704. The top end of the first bracket 701 is located above the sleeve 705, and the top end of the second bracket 702 is located below the sleeve 705. The first bracket 701 and the second bracket 702 can restrict the sleeve 705 from sliding along the axial direction of the column 704.

[0041] In one embodiment, the foot 703 has mounting holes to facilitate fixing it to the ground with screws, thereby fixing the support frame 7 to the ground.

[0042] In one embodiment, two sets of limiting rods 4 are provided, and the two sets of limiting rods 4 and one of the fixing rods 3 are distributed in an isosceles triangle. The clamping area formed in this way can stably hold the end of the reinforcing bar.

[0043] In one embodiment, an annular opening 3a is provided on the outer side of the fixing rod 3, and the annular opening 3a is used to restrict the vertical sliding of the reinforcing bar relative to the fixing rod 3.

This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein.
