[0002] Studs play an important role in construction projects, and their quality and performance directly affect the safety and stability of building structures. Therefore, it is very necessary to conduct a series of tests on studs to ensure that they can withstand various loads without breaking or being damaged during actual application. The bending test is one of the important tests. By bending the stud by 30°, the crack resistance and toughness of the stud under external force can be examined.
[0003] Common practice: Use heavy objects such as a hammer to hammer and bend the stud. After bending the stud by 30°, check whether there are visible cracks in the weld seam and heat affected zone of the stud. Since the hammering force cannot be controlled in this way, the bending angle of the stud cannot be controlled, which may cause the bending angle of the stud to be too large and damage the stud, and it is impossible to accurately determine whether the welding quality of the stud is qualified. Moreover, the operation of hammering the stud with a hammer is difficult, wasting labor and affecting the construction progress. Content of the Utility Model

A vertical bar-shaped chute 401 is formed at the central position of the pressing arm 4. A rectangular slider 8 is vertically slidably connected in the bar-shaped chute 401. Spring positioning seats 11 are fixedly connected to the bottom ends of the rectangular slider 8 and the bar-shaped chute 401 respectively. The upper and lower ends of the tension spring 12 are fixedly connected to the two spring positioning seats 11 respectively. A sliding rod 9 is fixedly connected to the front end of the rectangular slider 8. Two ends of an arc-shaped bracket 13 are fixedly connected to the left and right sides at the middle part of the top end of the bar-shaped base 1 respectively. An arc-shaped chute 1301 with a radian angle of 30° is formed at the upper left corner of the arc-shaped bracket 13. The arc center of the arc-shaped chute 1301 is coaxial with the articulated center of the articulated bracket 2. The sliding rod 9 passes through and is slidably connected in the arc-shaped chute 1301. When the sliding rod 9 is located at the right end of the arc-shaped chute 1301, its center is vertically collinear with the articulated center of the articulated bracket 2. A radial card slot 1302 is formed on the side facing the arc center at the left end of the arc-shaped chute 1301. The width of the radial card slot 1302 is the same as the width of the arc-shaped chute 1301. C-shaped hook brackets 14 are fixedly connected to the right end of the pressing arm 4 and the right side of the top end of the bar-shaped base 1 respectively. Two ends of the double-hook spring 15 are respectively hooked on the two C-shaped hook brackets 14. The double-hook spring 15 is in a tensioned state when the pressing arm 4 is vertically arranged; by arranging the double-hook spring 15, the pressing arm 4 can be kept in a vertical state all the time when the whole device is not in use; Fixed components are slidably arranged on the left and right sides of the bar-shaped base 1 along its length direction. The two groups of fixed components are respectively fixed on two welding nails adjacent to the welding nail to be bent. A limiting component is arranged at the left end of the bar-shaped base 1 for limiting its rightward horizontal movement relative to the fixed components.
[0024] In this embodiment, a pressure rod 5 is fixedly connected to the top end of the pressure arm 4, and an anti-slip sleeve 6 is sleeved and fixed on the pressure rod 5. The provided pressure rod 5 can provide a longer lever arm for the operator, making it more labor-saving during manual operation. The provided anti-slip sleeve 6 can prevent the operator from slipping when holding the pressure rod 5.
[0025] In this embodiment, a handle 10 is fixedly connected to the front end of the sliding rod 9. The provided handle 10 facilitates lifting the sliding rod 9 into the arc-shaped chute 1301 in a timely manner after the bending of the welding nail is completed.
[0026] In this embodiment, the fixing assembly includes: a T-shaped slider 16, a horizontal plate 17, a vertical plate 18, and a sleeve 19. Two T-shaped chutes 101 are symmetrically formed on the left and right sides of the strip-shaped base 1. The T-shaped slider 16 is horizontally slidably connected in the T-shaped chute 101. The top end of the T-shaped slider 16 is fixedly connected to the horizontal plate 17. The bottom end surface of the horizontal plate 17 is in contact and cooperation with the top end surface of the strip-shaped base 1. The middle part of the bottom end surface of the horizontal plate 17 is fixedly connected to the vertical plate 18. The rear end of the vertical plate 18 is fixedly connected to the sleeve 19. The sleeve 19 is cylindrical and a circular groove is formed at its bottom end. The size of the circular groove matches the size of the head of the welding nail. When the bottom end of the circular groove is in contact with the top end of the head of the welding nail, the bottom end surface of the strip-shaped base 1 is higher than or in contact with the welding surface of the welding nail. The position can be adjusted conveniently according to the actual distance between the welding nails by the fixing assembly that can slide left and right, so that the two fixing assemblies can be fixed on the two welding nails adjacent to the welding nail to be bent. The limiting assembly includes: a support plate 20, a screw 21, and a turning handle 22. The support plate 20 is vertically welded and fixed to the left end of the strip-shaped base 1. A threaded hole is formed in the support plate 20. The screw 21 passes through and is threadedly connected to the threaded hole. The left end of the screw 21 is fixedly connected to the turning handle 22. The screw 21 can abut against the vertical plate 18. When the two sleeves 19 are sleeved on the two welding nails adjacent to the welding nail to be bent, first adjust the position of the strip-shaped base 1 left and right so that the pressing block 7 can move from top to bottom and from right to left to a position in contact with the rod part of the welding nail to be bent. Then, drive the screw 21 to abut against the left vertical plate 18 by turning the turning handle 22. At this time, the strip-shaped base 1 cannot move left and right, realizing the bending of the welding nail when the whole device is in a fixed state.
[0027] When the device is in use, two sleeves 19 are sleeved on two welding studs adjacent to the welding stud to be bent. First, adjust the position of the strip-shaped base 1 left and right so that the pressing block 7 can move from top to bottom and from right to left to a position where it contacts the rod portion of the welding stud to be bent. Then, drive the screw rod 21 to abut against the left vertical plate 18 by turning the handle 22. At this time, the strip-shaped base 1 cannot move left and right. Hold the anti-slip sleeve 6 and turn the pressing rod 5 counterclockwise, and then drive the pressing block 7 through the pressing arm 4 to apply force to the rod portion of the welding stud to bend the welding stud. Since the radian angle of the arc-shaped chute 1301 is 30°, when the sliding rod 9 moves from the right end to the left end of the arc-shaped chute 1301, the 30° bending of the welding stud can be completed, and the operation is convenient. When the sliding rod 9 moves to the left end of the arc-shaped chute 1301, it will be caught in the radial card slot 1302 under the pull of the tension spring 12. At this time, leave it still for a period of time to prevent the incomplete plastic deformation of the welding stud and avoid affecting the bending angle of the welding stud due to incomplete plastic deformation. After the welding stud is bent, lift the sliding rod 9 into the arc-shaped chute 1301 through the provided handle 10, and then reset it under the pull of the double-hook spring 15. After the device is used, drive the screw rod 21 away from the left vertical plate 18 by turning the handle 22, and then remove the entire device from left to right and from bottom to top.
