Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] Reference Figure 1-4 As shown, a wheel-type steel stretching device includes a module 1 and a module 2. The structure of module 1 and module 2 is the same. A connecting rod 9 is fixed between the upper ends of the two fixing frames 101 of module 1 and the two fixing frames 101 of module 2. The connecting rod 9 is set to a "U" shape, thereby forming a rectangular frame.

[0034] At the same time, the steel bar threading form of the tensioning device is as follows Figure 1 As shown, the steel bar straightening is achieved.

[0035] Module 1 includes two fixing frames 101 fixed on opposite sides of the ground. The fixing frames 101 are angle irons. A rack 104 is fixed on one side of the outer surface of the fixing frame 101 of module 1 and the outer surface of the fixing frame 101 of module 2. A longitudinal groove 108 is provided in the middle of the four fixing frames 101 and the four racks 104. A double-layer slider 107 is longitudinally slidably provided in the longitudinal groove 108. The structure of the double-layer slider 107 is as shown in FIG. Figure 4 As shown, the double-layer slider 107 is configured to be rectangular, and the surface of one end of the double-layer slider 107 is in close contact with the surface of the longitudinal groove 108 and can slide.

[0036] A turntable 102 is fixed between the facing surfaces of the two double-layer sliders 107 of module 1, and at least four cylinders 103 are fixed around and equally divided between the two turntables 102. The specific number of cylinders 103 needs to be set according to actual conditions. The steel bar will slide on the surface of the cylinder 103 under force to achieve a straightening effect. The turntable 102 and cylinder 103 of module 2 are always arranged diagonally to the turntable 102 and cylinder 103 of module 1, and the turntable 102 and cylinder 103 of module 1 are located at the oblique upper end of the turntable 102 and cylinder 103 of module 2, and the limit ring 3 can make the steel bar present an 'N' shape as shown in FIG. Figure 1 shown.

[0037] The two fixing frames 101 are located on one side of the rack 104 and are both provided with a limiting tooth 109 meshing with the rack 104. The meshing of the limiting tooth 109 with the rack 104 can limit the double-layer slider 107 to keep it in the desired position. An L-shaped seat 105 is fixed to the end of the double-layer slider 107 away from the turntable 102. A 2mm gap is left between one end of the L-shaped seat 105 and the end of the tooth of the rack 104, which can make the device structure more compact while not causing interference between the structures. A through hole is provided on one side of the upper end of the L-shaped seat 105, and a sliding rod 1092 fixed to the middle part of one side of the limiting tooth 109 is movably penetrated through the through hole. A handle 106 is fixed to the end of the sliding rod 1092 away from the double-layer slider 107, and a movable door ring is provided on the surface of the handle 106 for the convenience of the user to pull.

[0038] A spring 1091 is sleeved on the outer side of the slide rod 1092. In order to reduce the distortion of the spring 1091, the inner wall of the spring 1091 needs to fit with the outer wall of the slide rod 1092, thereby limiting the spring 1091. The two ends of the spring 1091 are respectively in contact with the surface of the L-shaped seat 105 and the surface of the limiting tooth 109, and the spring 1091 can be driven and compressed by the limiting tooth 109.

[0039] Under normal conditions, the limiting tooth 109 is always meshed with the rack 104 under the push of the elastic force of the spring 1091 , thereby fixing the position of the rotating disk 102 .

[0040] The side of the module 2 2 away from the module 1 1 is provided with an L-shaped base 4 and a winding device 8 fixed to the upper end of the ground in sequence. It should be noted that the winding device 8 is a prior art, and the winding device 8 disclosed in the above-mentioned patent CN202022039943.9 can also be used. The L-shaped base 4, the module 2 2, the module 1 1 and the winding device 8 can all be abutted and fixed, thereby reducing the volume of the device. A plurality of straightening devices are provided on one side of the L-shaped base 4, and the plurality of straightening devices include a straightening tube 5 fixed in the middle of one side of the L-shaped base 4 and a straightening wheel 2 7 and a straightening wheel 1 6 obliquely symmetrically arranged at the upper end of one side of the L-shaped base 4. The straightening tube 5 is a prior art, and its structure will not be described in detail. The straightening wheel 2 7 and the straightening wheel 1 6 are both located at the upper end of the straightening tube 5. After being straightened by the straightening device, the steel bar is wound and rolled on the winding wheel surface of the winding device 8. The winding wheel is one component of the winding device 8.

[0041] A connecting plate 10 is fixed between the two fixing frames 101 of module 1, and a limiting ring 3 is fixed on the upper end of the connecting plate 10 at one side of the straightening wheel 2 7. The limiting ring 3 is located at the lower end of the cylinder 103 of module 1, and at the same time, the limiting ring 3 is the entrance of the steel bar.

[0042] Principle and process of this utility model:

[0043] Before stretching the steel bar, you first need to adjust the equipment according to the diameter of the steel bar:

[0044] The adjustment method of module 1 and module 2 is the same. First, the user pulls the handle 106 by hand, and the handle 106 drives the slide rod 1092 to slide on the L-shaped seat 105 while compressing the spring 1091 through the limit tooth 109. At this time, the limit tooth 109 will separate from the rack 104, thereby causing the double-layer slider 107 to move longitudinally in the longitudinal groove 108, thereby driving the turntable 102 and the cylinder 103 to move longitudinally, thereby causing the cylinder 103 of module 1 and the cylinder 103 of module 2 to be misaligned.

[0045] When the cylinder 103 of the module 1 is moved to a suitable height, the user releases the handle 106 to engage the limiting tooth 109 with the rack 104 , thereby limiting the position of the double-layer slider 107 .

[0046] Afterwards, the user passes the steel bar through the middle of the limiting ring 3, then wraps it around the lower end of the cylinder 103 of module 2 to the upper end and pulls it to the lower end of the cylinder 103 of module 1 to the upper end and passes it out from the serial port in the middle of the straightening tube 5, then wraps it around the lower end of the straightening wheel 1 6 to the upper end and then wraps it around the lower end of the straightening wheel 2 7 to the upper end. Then, one end of the steel bar passes through the tensioner and is wrapped around the wheel disc of the winding device 8, thereby winding the steel bar.

[0047] By using the above device, the steel bar can be continuously wound, thereby increasing the friction between the surface of the steel bar and the surface of the cylinder 103, thereby achieving different stretching and straightening effects. At the same time, the cylinders 103 of module 1 and module 2 2 can be adjusted separately, thereby changing the angle of the steel bar and thus changing the friction.

[0048] The stretcher is a common structure of existing stretching devices and will not be described in detail.

[0049] The stretching and straightening machine of the device utilizes the longitudinal space when straightening the steel bars, thereby reducing the space occupied in the factory building, and has a reasonable structural design and is easy to use; secondly, when straightening the steel bars, the angle of the straightening device is adjustable and can be adjusted according to the diameters of different steel bars, thereby improving the straightening effect of the steel bars.

[0050] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
