Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the problem that the existing mechanical device for making cold-rolled ribbed steel bar is twisted into one from the two ends of the two steel bars, the two ends of the two steel bars are subjected to a large force and the middle part is subjected to a relatively large force. Small, the middle part of the steel bar workpiece is not easy to form, resulting in the technical problem that the overall shape and structure of the finally twisted steel bar workpiece is irregular. The invention provides a high-elongation cold-rolled ribbed steel bar workpiece manufacturing device

Embodiment 1

[0032] Such as Figures 1 to 6As shown, the present embodiment provides a high-elongation cold-rolled ribbed steel bar workpiece manufacturing device, including a casing 1, which is provided with an upper clamping mechanism 2 and a lower clamping mechanism for fixing steel bars, the upper clamping The mechanism 2 and the lower clamping mechanism are symmetrically arranged up and down. A twisting sleeve 3 is arranged between the upper clamping mechanism 2 and the lower clamping mechanism. Inside the twisting sleeve 3, there is a clamping hole 3.1 that allows steel bars to pass through. The twisting sleeve 3. A number of driven teeth 4 are evenly distributed on the outer wall in the circumferential direction, and the torsion sleeve 3 is engaged with the driving gear 5.

[0033] In this embodiment, when making steel bars, first select two suitable steel bars to pass through the upper clamping mechanism, the twisting sleeve and the lower clamping mechanism in turn, and the two ste...

Embodiment 2

[0035] Such as Figures 1 to 5 As shown, this embodiment is further optimized on the basis of embodiment 1. Specifically, the upper clamping mechanism 2 includes a seat plate 2.1 fixed in the casing 1, and the bottom of the seat plate 2.1 is provided with a matching torsion sleeve 3 A rotating circular groove, a cover plate 2.2 is arranged above the seat plate 2.1, two left and right symmetrical clamping pieces 2.3 are hinged between the cover plate 2.2 and the seat plate 2.1, a torsion spring 2.4 is arranged on the top of the cover plate 2.2, and the torsion spring 2.4 Two spring wires 2.4.1 extend out and are respectively connected to the top of the corresponding clamping part 2.3. The two clamping parts 2.3 have a tendency to rotate in the opposite direction under the action of the corresponding spring wire 2.4.1, and the seat plate 2.1 has limited settings. The position U-shaped plate 2.5, the two clamping parts 2.3 are located in the U-shaped groove of the limit U-shaped ...

Embodiment 3

[0038] Such as Figures 1 to 5 As shown, this embodiment is further optimized on the basis of embodiment 2. Specifically, the side wall of the casing 1 is provided with an observation port 8 facing the upper clamping mechanism 2, the lower clamping mechanism and the torsion sleeve 3. , the torsion sleeve 3 is provided with a vertical positioning slot 9, the driving gear 5 is connected with the second reducer 10 through the transmission shaft, the second reducer 10 is connected with the second motor 11, the driving gear 5, the second Both the reducer 10 and the second motor 11 are inside the casing 1 .

[0039] In this embodiment, the driving gear can drive the torsion sleeve to rotate by starting the second motor. The observation port provided on the side wall of the casing is to facilitate the observation of the fixing of the internal steel bars. There is a vertical arrangement on the torsion sleeve. Positioning through slot, every time the positioning through slot passes th...

Description

technical field [0001] The invention relates to the technical field of mechanical devices for making steel bars, in particular to a high-elongation cold-rolled ribbed steel bar workpiece making device. Background technique [0002] Cold-rolled ribbed steel bars are made by rolling hot-rolled steel bars at room temperature through a rolling mill. Compared with hot-rolled smooth round steel bars, it can save 35%-40% of steel materials for cast-in-place structures (especially in building roofs). According to the steel market price, every ton of cold-rolled ribbed steel bars used can save about 800 yuan in steel costs. (2) The bonding and anchoring performance between the cold-rolled ribbed steel bar and the concrete is good, so it is used in the component, which fundamentally eliminates the phenomenon of cracking in the anchorage area of ​​the component, and the phenomenon of steel wire slipping and damage, and improves the strength of the component end. Bearing capacity and ...
