Abstract
The utility model discloses a moderate straightening device for a continuous heat treatment production line, and belongs to the field of reinforcing steel bar straightening equipment. The moderate straightening device comprises a rack. Two straightening roll sets are arranged on the rack. The moderate straightening device is characterized in that the two straightening roll sets form a 90-degree angle, each straightening roll set is composed of three fixed idler wheels and two moving idler wheels, and the fixed idler wheels and the moving idler wheels are arranged side by side in a staggered mode in two rows. The moderate straightening device further comprises a sliding rail, a sliding block and a screw rod, wherein the sliding rail is fixed on the rack, the sliding block is matched with the sliding rail, and the screw rod is used for adjusting the sliding block. The direction of the sliding rail is perpendicular to the axial direction of the moving idler wheels. The moving idler wheels are mounted on the sliding block. The fixed idler wheels are fixed on the rack. According to the moderate straightening device for the continuous heat treatment production line, the moderate straightening device is additionally arranged behind a backfire unit of the continuous heat treatment production line, waste heat of backfire is utilized for continuously straightening reinforcing steel bars, and the slack value of products can be higher than the slack value required by the GB/T5223.3-2005 on the premise that material cost and heating cost are not increased.
Description
Technical field
The utility model belongs to bar straightening and equips the field, is specifically related to gren rod through carry out the temperature correction device of the straight operation of temperature correction after the drawing moulding on the continuous heat production line.
Background technology
At present, when the gren rod production deformed bar that utilizes on the continuous heat production line after the drawing moulding, the prestress steel relaxation value often can occur greater than 2.0%, not meet the requirement of standard GB/T/T5223.3-2005.For this problem, traditional solution often needs the chemical composition of feed change, or the temperature when improving heat treatment, and this can increase cost of material or heating cost undoubtedly.
Summary of the invention
The purpose of this utility model aims to provide a kind of continuous heat production line temperature correction device.
Based on above-mentioned purpose, the utility model has been taked following technical scheme:
Continuous heat production line temperature correction device, at continuous heat production line tempering unit rear organic frame, it is characterized in that: two groups of smoothing rolls that are mutually 90 degree are arranged on frame, and every group of smoothing roll decide roller by three and two moving rollers form, and decide roller and moving roller and divides two to arrange to interlock and place side by side.
Described temperature correction device also comprises the screw mandrel of the slide rail that is fixed on frame, the slide block that coordinates with slide rail and adjusting slider; To vertical, moving roller is arranged on slide block the slide rail direction with moving roller shaft; Deciding roller is fixed on frame.
The utility model is set up the temperature correction device by the tempering unit rear at the continuous heat production line, utilize the tempering waste heat to carry out continuous straightening to reinforcing bar, can be under the prerequisite that does not increase cost of material and heating cost Improving The Quality of Products: the relaxation test of 1000h when being 70% nominal tensile strength to utilizing product that this device is produced to carry out primary stress, lax value is all 1～1.5%, be better than GB/T5223.3-2005 to lax value less than 2.0% requirement.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Continuous heat production line temperature correction device, as shown in Figure 1, comprise two groups of smoothing rolls that are mutually 90 degree on the frame (3) that is arranged on continuous heat production line tempering unit rear, every group of smoothing roll decides roller (1) by three and two moving rollers (2) form, and decides roller (1) and moving roller (2) minute two rows are staggered to place side by side.
Described temperature correction device also comprises the screw mandrel (5) of the slide rail (4) that is fixed on frame (3), the slide block (6) that coordinates with slide rail (4) and adjusting slider (6); Slide rail (4) direction is axially vertical with moving roller (2), and moving roller (2) is arranged on slide block (6); Deciding roller (1) is fixed on frame (3).
Rotary screw (5) can make slide block (6) mobile along slide rail (4), and then roller (2) is subjected to displacement, and moving roller (2) is adjusted with the spacing of deciding roller (1).Two moving rollers (2) exert pressure successively for reinforcing bar (7), make reinforcing bar (7) recur four deformation, obtain required reinforcing bar (7) the straightening deformation amount of technique.Usually, this deflection is controlled at 2～3%.
Claims (2)
1. continuous heat production line temperature correction device, comprise frame (3), it is characterized in that: two groups of smoothing rolls that are mutually 90 degree are arranged on frame (3), every group of smoothing roll decides roller (1) by three and two moving rollers (2) form, and decides roller (1) and moving roller (2) minute two rows are staggered to place side by side.
2. continuous heat production line temperature correction device as claimed in claim 1, it is characterized in that: described temperature correction device also comprises the screw mandrel (5) of the slide rail (4) that is fixed on frame (3), the slide block (6) that coordinates with slide rail (4) and adjusting slider (6); Slide rail (4) direction is axially vertical with moving roller (2), and moving roller (2) is arranged on slide block (6); Deciding roller (1) is fixed on frame (3).
