Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to coiled steel bars, especially a coiled steel bar straightening device. Background Technology

[0002] Spiral straightening refers to the process of straightening spirally coiled metal materials (such as rebar and wire rod). These materials are typically transported or stored in coil form, but need to be straightened for subsequent processing or mechanical property testing. The purpose of straightening is to eliminate bending or twisting of the material, ensuring it meets the specifications required for use or testing. Currently, spiral straightening is achieved using roller straightening machines. However, changing the molds on roller straightening machines requires disassembling many rollers, consuming a significant amount of time and resulting in low changeover and straightening efficiency. Summary of the Invention

[0003] The purpose of this utility model is to provide a spiral straightening device, which aims to solve the technical problems of low replacement efficiency and low straightening efficiency of existing roller straightening machines.

[0004] This utility model discloses a spiral straightening device, including a working platform with a fixed support plate. Two vertical drive devices are spaced apart along the front-rear direction on the lower side of the working platform. The output shafts of the vertical drive devices pass upward through the support plate and are connected to an upper baffle. An upwardly protruding step is provided on the upper right end of the support plate. A support plate is provided on the support plate, located below the upper baffle. The right side of the support plate abuts against the left side of the step. Two positioning grooves are provided on the right side of the support plate, and the output shafts of the two vertical drive devices are respectively engaged in the two positioning grooves. A push plate is provided on the support plate to the left of the support plate. A transverse drive device is provided on the working platform to the left of the push plate. The output shaft of the transverse drive device is detachably connected to the push plate.

[0005] Furthermore, the output shaft of the vertical drive device is provided with a first stop, and the upper baffle is provided with a second stop that cooperates with the first stop. After the output shaft of the vertical drive device passes through the upper baffle, washers and cap nuts are arranged sequentially from bottom to top.

[0006] Furthermore, the output shaft of the transverse drive device is threadedly connected to a connecting plate and locked with a round nut. The right side of the connecting plate is provided with a groove, and the push plate is engaged in the groove of the connecting plate. The connecting plate is fixed to the push plate by at least two pins spaced apart in the front-back direction.

[0007] Furthermore, the vertical drive device is fixed to the work platform by screws.

[0008] Furthermore, the vertical drive device and the horizontal drive device are hydraulic cylinders.

[0009] Compared with existing technologies, the advantages of this invention are positive and significant. This invention can be used for rapid straightening of coiled screws of various diameters. It has a simple structure, is easy to operate, occupies little space, and allows for quick mold changes. Only the push plate and support plate need to be replaced to straighten coiled screws of different specifications. The straightening speed is fast; compared to conventional roller straightening machines that require more than 10 seconds to complete a single coiled screw sample, this invention only requires 5 seconds. This significantly improves efficiency in mold changes and testing. Attached Figure Description

Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0016] like Figures 1-5 As shown, a spiral straightening device of this utility model includes a working platform 1, on which a bearing plate 12 is fixedly mounted. Two vertical drive devices 14 are spaced apart along the front-back direction on the lower side of the working platform 1. The output shaft of the vertical drive device 14 passes upward through the bearing plate 12 and is connected to an upper baffle 8. An upwardly protruding step 16 is provided on the upper right end of the bearing plate 12. A support plate 11 is provided on the bearing plate 12, located below the upper baffle 8. The right side of the support plate 11 abuts against the left side of the step 16. Two positioning grooves 17 are provided on the right side of the support plate 11. The output shafts 15 of the two vertical drive devices 14 are respectively engaged in the two positioning grooves 17. A push plate 7 is provided on the bearing plate 12 to the left of the support plate 11. A transverse drive device 2 is provided on the working platform 1 to the left of the push plate 7. The output shaft 3 of the transverse drive device 2 is detachably connected to the push plate 7.

[0017] Furthermore, the output shaft 15 of the vertical drive device 14 is provided with a first stop, and the upper baffle 8 is provided with a second stop that cooperates with the first stop. After the output shaft 15 of the vertical drive device 14 passes through the upper baffle 8, a washer 10 and a cap nut 9 are arranged sequentially from bottom to top.

[0018] Furthermore, the output shaft of the transverse drive device 2 is threadedly connected to a connecting plate 5 and locked by a round nut 4. A groove is provided on the right side of the connecting plate 5, and the push plate 7 is engaged in the groove of the connecting plate 5. The connecting plate 5 is fixed to the push plate 7 by at least two pins 6 spaced apart in the front-back direction.

[0019] Furthermore, the vertical drive device 14 is fixed to the work platform 1 by screws.

[0020] Furthermore, the vertical drive device 14 and the horizontal drive device 2 are hydraulic cylinders.

[0021] Specifically, the specific structure and principle of the vertical drive device 14, hydraulic cylinder, horizontal drive device 2 and other components in this embodiment, as well as other aspects not described in detail, all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be elaborated here.

[0022] The working principle of this embodiment:

[0023] When assembling this device, the output shaft 15 of the vertical drive device 14 drives the upper baffle 8 to rise. The support plate 11 is then inserted between the bearing plate 12 and the upper baffle 8, and the positioning groove 17 of the support plate 11 is secured to the output shaft 15 of the vertical drive device 14. The push plate 7 is then installed into the groove of the connecting plate 5, and all the pins 6 are installed. During operation, a coiled screw sample 13 (e.g., ...) is inserted between the bearing plate 12 and the upper baffle 8, and onto the left side of the support plate 11. Figure 4 (As shown), then the output shaft 15 of the vertical drive device 14 drives the upper baffle 8 to descend. The upper baffle 8 touches the coiled screw sample 13 or the support plate 11. The output shaft 3 of the horizontal drive device 2 pushes the push plate 7 to the right. The push plate 7 squeezes and straightens the coiled screw sample 13. The support plate 11 supports the coiled screw sample 13. In this way, one test is completed. The straightened coiled screw sample 13 is taken out from the side.

[0024] When changing molds to straighten coiled screws of different specifications, simply retract the horizontal drive device 2, drive the vertical drive device 14 to drive the upper baffle 8 to the highest point, remove all the pin parts 6, remove the original push plate 7 and the original support plate 11, and replace them with the new push plate 7 and support plate 11 using the same installation method.

[0025] This invention can be used for rapid straightening of coiled screws of various diameters. It has a simple structure, is easy to operate, occupies little space, and allows for quick mold replacement. Only the push plate 7 and support plate 11 need to be replaced to straighten coiled screws of different specifications. The straightening speed is fast. Compared with the conventional roller straightening machine, which takes more than 10 seconds to complete a coiled screw sample 13, this invention only takes 5 seconds. The efficiency of mold replacement and testing is significantly improved.
