[0001] The utility model relates to the technical field of steel components, in particular to a bolt bending device on a steel component. Background Art

[0002] Steel components refer to steel structure composite components that can bear and transfer loads and are made of steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels that are cold-bent or welded through connectors. With the rapid development of society, steel components are widely used in all walks of life. In all walks of life, people generally weld studs on steel components for use. In order to check whether the studs meet the standards in the welding of steel components, the welding studs on the steel components are generally subjected to bending tests.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. In the utility model, the sleeve tube is sleeved on the welding bolt, and the two semicircular positioning plates cooperate with each other so that the welding bolt is located exactly in the center of the sleeve tube. The indicator rod and the stop rod are rotated by the rotation of the horizontal plate, so that the inclination angle of the stop rod is the same as the specific bending angle of the welding bolt.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-5 The bolt bending device on a steel member shown in the figure comprises a second U-shaped plate 2 fixedly mounted on the top of the first U-shaped plate 1, the second U-shaped plate 2 is fixedly mounted on the first U-shaped plate 1 by welding, an electric push rod 3 is fixedly mounted on the outer wall of one side of the second U-shaped plate 2, an annular push plate 5 is fixedly mounted on the output shaft of the electric push rod 3, a sleeve tube 4 is movably mounted in the annular push plate 5, in order to reduce the friction between the annular push plate 5 and the sleeve tube 4 so that the sleeve tube 4 can move more smoothly in the annular push plate 5, a plurality of rolling balls 6 are rotatably mounted in the annular push plate 5, and the sleeve tube 4 passes through the annular push plate 5, two placing rods 7 are fixedly mounted on the sleeve tube 4, a protractor plate 17 is fixedly mounted on the top of the first U-shaped plate 1, a vertical plate 12 is fixedly mounted on the protractor plate 17, and the vertical plate 1 2 is provided with a threaded hole, and an adjusting screw 13 passes through the threaded hole and rotates with the inner wall of the threaded hole. An adjusting screw 13 is threadedly installed on the vertical plate 12, and a horizontal plate 14 is fixedly installed on one end of the adjusting screw 13. A stopper 15 and an indicator rod 16 are fixedly installed on the outer wall of one side of the horizontal plate 14. The indicator rod 16 points to the angle scale line on the protractor plate 17. The inclination angle of the stopper 15 is accurately adjusted to be the same as the specific bending angle of the welding bolt. The electric push rod 3 is started, and the output shaft of the electric push rod 3 is extended to drive the annular push plate 5 to move. The movement of the annular push plate 5 drives the sleeve tube 4 to rotate downward. The sleeve tube 4 rotates to bend the welding bolt. When the sleeve tube 4 rotates and drives it to contact with the stopper 15, it means that the welding bolt has just reached the required bending angle, thereby accurately controlling the bending angle of the welding bolt.

[0021] In order to quickly position the welding bolt and make it located in the middle position of the sleeve tube 4, two fixing plates 8 are fixedly installed in the sleeve tube 4, and sliding rods 9 are slidably installed on the two fixing plates 8. In order to reduce the friction between the sliding rod 9 and the fixing plate 8, thereby reducing the wear of the sliding rod 9 and increasing the service life of the sliding rod 9, through holes are respectively opened on the two fixing plates 8, and linear bearings are fixedly installed in the two through holes. The two sliding rods 9 respectively penetrate the two linear bearings and are slidably connected to the inner walls of the two linear bearings respectively. Semicircular positioning plates 11 are respectively fixedly installed on the bottom ends of the two sliding rods 9, and two semi-funnel-shaped holes are respectively opened on the two semi-circular positioning plates 11. Since the two semi-funnel-shaped holes are large at the bottom and small at the top, the semi-funnel-shaped holes can be used to quickly position welding bolts of different diameters.

[0022] In order to limit the sliding rod 9 so that the sliding rod 9 is always slidably mounted on the fixing plate 8 , the top ends of the two sliding rods 9 are respectively fixedly mounted with limiting plates 10 .

[0023] The working principle of the bolt bending device on a steel member provided by the utility model is as follows: when people need to use the device, the device is moved so that the welding bolt is located between the first U-shaped plate 1, and the sleeve tube 4 is sleeved on the welding bolt. The two semicircular positioning plates 11 cooperate with each other to make the welding bolt just located in the central position of the sleeve tube 4. When it is necessary to bend the welding bolt to a specific angle, the cross plate 14 is rotated, and the rotation of the cross plate 14 drives the indicator rod 16 and the stop rod 15 to rotate. The indicator rod 16 points to the angle scale line on the protractor plate 17, and the inclination angle of the stop rod 15 is accurately adjusted to be the same as the specific bending angle of the welding bolt. The electric push rod 3 is started, and the output shaft of the electric push rod 3 is extended to drive the annular push plate 5 to move. The movement of the annular push plate 5 drives the sleeve tube 4 to rotate downward, and the sleeve tube 4 rotates to bend the welding bolt. When the sleeve tube 4 rotates and drives it to contact the stop rod 15, it means that the welding bolt has just reached the required bending angle, thereby accurately controlling the bending angle of the welding bolt.

[0024] Compared with the related art, the bolt bending device on the steel member provided by the utility model has the following advantages:

[0025] Beneficial effects:

[0026] The utility model provides a bolt bending device on a steel member, wherein a sleeve tube 4 is sleeved on a welding bolt, and two semicircular positioning plates 11 cooperate with each other so that the welding bolt is located exactly at the center of the sleeve tube 4, and a horizontal plate 14 is rotated to drive an indicator rod 16 and a stop rod 15 to rotate, so that the inclination angle of the stop rod 15 is the same as a specific bending angle of the welding bolt, and the sleeve tube 4 is driven to rotate and the welding bolt is bent by extending the output shaft of an electric push rod 3. When the sleeve tube 4 is rotated and driven to contact the stop rod 15, it indicates that the welding bolt has just reached the required bending angle, thereby accurately controlling the bending angle of the welding bolt.
