Description

Technical Field

[0001] The present application relates to the technical field of steel bar bending and welding equipment, and in particular to a steel bar bending and welding equipment. Background Art

[0002] During the construction of the assembled box concrete hollow floor, it is necessary to tie the main reinforcement and the stirrups to form a square steel cage as a part of the rib beam. The existing square stirrup cage bending and welding equipment includes a stirrup bending machine and an automatic welding mechanism. The stirrup bending machine is usually a five-head steel bar stirrup bending machine. After the steel bars are sent to the bending station of the stirrup bending machine through the feeding mechanism, the five heads are bent in turn. The driving mechanism drives the bending plate or the bending pin on the bending machine head to rotate against the steel bar and drive the steel bar to rotate and bend around the machine core, bending the steel bar into a square stirrup. The head and tail of the stirrup are bent to form a hook. After each head completes the bending action The movement is driven by its driving mechanism to shrink and make room for bending. After the stirrups are bent and formed, they are manually carried to the loading place of the automatic welding mechanism, and the main bars are manually arranged in a square shape at the loading place. The stirrups are arranged on the outside of the main bars, and the main bars are driven to move axially by the pushing mechanism of the automatic welding mechanism. The pushing mechanism is usually a clamping mechanism that can move on a guide rail and is used to clamp the main bars, or a pushing arm with a clamping mechanism. At the same time, the mechanical swing arm swings to separate adjacent stirrups by a rated spacing, and the automatic welding gun welds the welding points of the stirrups and the main bars in turn to complete the bending and welding of the stirrup cage.

[0003] However, during the use of traditional stirrup cage bending and welding equipment, the required number of stirrups needs to be counted manually when loading, which is prone to missing or insufficient reinforcement. In addition, the hooks of the stirrups are usually arranged on one side of the steel cage, which can easily lead to stress concentration in the formed steel cage during use. It is time-consuming and laborious to manually stagger the corresponding positions of the hooks of adjacent stirrups during loading, which increases the difficulty of stirrup arrangement and affects the efficiency and quality of the stirrup cage bending and welding. Summary of the invention

[0004] The present application proposes a steel bar bending and welding device, which has the advantages of alternately staggered bending and welding of the hooks of adjacent stirrups and improved bending and welding efficiency, and is used to solve the problem of the complicated and difficult stirrup feeding process.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions: a steel bar bending and welding device, comprising a support seat, both sides of the support seat are fixedly provided with bending hoop mechanisms, the bending hoop mechanisms are used to bend the steel bars to form the top and the first and tail hooks of the hoop bars, the inner side of the support seat is fixedly connected with a fixed seat, the bottom of the fixed seat is provided with a bending mechanism, one side of the fixed seat is provided with a plurality of movable sleeves, the number of the movable sleeves is adapted to the number of main bars, the bending mechanism is used to cooperate with the corresponding movable sleeves to bend the steel bars to form the vertical part of the hoop bars, and the movable sleeves are sleeved on the outer side of the main bars;

[0006] It also includes an adjustment mechanism whose number is compatible with the movable sleeve, and the movable sleeve is used to adjust the position of the main reinforcement so that the position of the main reinforcement is offset from the rotation trajectory of the bending part of the stirrup. The adjustment mechanism can drive the movable sleeve to move after the stirrup is bent and formed, so that the main reinforcement returns to the contact position with the stirrup.

[0007] The beneficial effects of the present invention are as follows:

[0008] The present application provides a steel bar bending and welding device, which adjusts the position of the main bar by means of a movable sleeve arranged on the outside of the main bar, so that the main bar avoids the bending trajectory of the hook end of the stirrup during the bending process, and the steel bar cage formed after the stirrup is bent is arranged on the outside of the main bar. Compared with the traditional stirrup cage bending and welding equipment, it does not need to unload the material from the stirrup machine and then manually load the material, thus avoiding the problems of missed bars and insufficient bars during the loading process, and the bending and hoop bending mechanism cooperates with the bending mechanism to adjust the forming position of the hooks after the adjacent stirrups are bent, so that the hooks of adjacent stirrups on the formed steel bar cage are staggered with each other, thus avoiding the situation where the hooks of the stirrups are located on the same side of the steel bar cage, causing stress concentration in the formed steel bar cage. After the stirrups are bent, the adjusting mechanism drives the movable sleeve to move, driving the main bar to approach the stirrups and contact the stirrups, thus facilitating the subsequent welding of the main bar and the stirrups, thereby achieving the effect of improving the forming quality of the stirrup cage and the bending and welding efficiency of the stirrup cage.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the drawings provided in the specification, due to the large proportions of some structural features, for example, the proportion between the main reinforcement 15 and the stirrups 16 in the present invention is too large, it may be difficult to intuitively understand the specific structure or working principle of the present invention when reading the drawings. In order to more clearly show the details and features of the present invention, the proportions of some structural features and their accessories in the drawings of the specification of the present invention have been adjusted to facilitate intuitive understanding of the specific structure of the present invention.

[0022] Embodiment 1, as Figure 1-Figure 5 and Figure 8A steel bar bending and welding device comprises a support seat 19, and bending hoop mechanisms 20 are fixedly arranged on both sides of the support seat 19. The bending hoop mechanism 20 is a double-head bending hoop device. The bending hoop mechanism 20 is used to bend the steel bar part to form the top and the first and tail hooks of the stirrup 16. When bending the hoop, the feeding mechanism conveys the steel bar to the rated position on the bending hoop mechanism 20. The clamping mechanism arranged on the feeding mechanism ensures the bending angle of the bending process. The two bending hoop mechanisms 20 first bend the two ends of the steel bar respectively to form the first and tail hooks of the stirrup 16. Figure 3 The shape of the hook is an inverted hook. After the hook is bent and formed, the corresponding movement shrinks, and then one of the two bending hoop mechanisms 20 bends the steel bar again to form the top straight section of the stirrup 16. The movement of the other bending hoop mechanism 20 of the two bending hoop mechanisms 20 remains contracted, so that the hook is formed on one side of the square steel cage in the subsequent bending process of the stirrup 16. When bending different steel bars, the two bending hoop mechanisms 20 alternately bend the top straight section of the stirrup 16, so that the hook positions of adjacent stirrups 16 on the formed steel cage are staggered, and are respectively located on both sides of the square steel cage, thereby ensuring the quality of the square steel cage.

[0023] The support seat 19 is annular, and a fixed seat 7 is fixedly connected to the inner side of the support seat 19. Both sides of the bottom of the fixed seat 7 are rotatably connected to a rotating seat 8. A bending plate 5 for bending stirrups 16 is fixedly connected to one side of the rotating seat 8. A No. 2 driving mechanism 37 is provided on one side of the fixed seat 7. The No. 2 driving mechanism 37 is used to drive the rotating seat 8 to rotate. The rotating seat 8 rotates to drive the bending plate 5 to rotate. The main reinforcement 15 passes through the fixed seat 7 and the spacing between adjacent main reinforcements 15 is less than the distance between the main reinforcements 15 of the formed steel cage. A plurality of movable sleeves 1 are provided on one side of the fixed seat 7. The number of movable sleeves 1 is adapted to the number of main reinforcements 15. The movable sleeves 1 are movably sleeved on the outer sides of the corresponding main reinforcements 15. The movable sleeves 1 are used to adjust the distance between the corresponding welding points of the main reinforcement 15 and the stirrups 16. A No. 1 driving mechanism 18 is fixedly provided on one side of the fixed seat 7. The number of the No. 1 driving mechanism 18 is adapted to the number of the movable sleeves 1. The No. 1 driving mechanism 18 can be set as an electric push rod, and the output end of the electric push rod is fixedly connected with a connecting block 17.

[0024] The No. 1 driving mechanism 18 can also be set as a hydraulic push rod fixedly connected to the connecting block 17. The No. 1 driving mechanism 18 is used to drive the connecting block 17 to move. A movable plate 3 is fixedly connected to one side of the connecting block 17. The bottom of the movable plate 3 is fixedly connected to the air cylinder 2. A T-shaped rod 6 is slidably sleeved on the inner side of the air cylinder 2. The end of the T-shaped rod 6 with a small diameter is located on the outside of the air cylinder 2 and is fixedly connected to the movable sleeve 1. The diameter of the wide end of the T-shaped rod 6 is adapted to the inner diameter of the air cylinder 2. The T-shaped rod 6 divides the inside of the air cylinder 2 into two cavities. A vent is provided on the inner wall of the cavity on the side close to the movable plate 3, which is connected to the air on the outside of the air cylinder 2. After the two bending hoop mechanisms 20 are completed, the No. 2 driving mechanism 37 drives the bending plate 5 to rotate, and the bending plate 5 abuts against one side of the stirrup 16, so that the stirrup 16 abuts against the outer wall of the moving sleeve 1.

[0025] The bending plate 5 rotates to bend the stirrup 16 to form the vertical part of the stirrup 16 of the square steel cage, thereby completing the bending of the stirrup 16. At this time, the movable sleeve 1 fixes the position of the main reinforcement 15, so that the main reinforcement 15 is always located on the inner side of the square formed by the stirrup 16 during the bending process of the stirrup 16. Therefore, when the bending plate 5 drives the stirrup 16 to bend, the movable sleeve 1 located at the top makes the corresponding main reinforcement 15 avoid the rotation track of the hook during the bending process of the stirrup 16, so as to avoid the main reinforcement 15 blocking the stirrup 16 and causing the bending failure. After the stirrup 16 is formed, The electric push rod drives the connecting block 17 to move, the connecting block 17 drives the moving plate 3 to move, the moving plate 3 drives the air cylinder 2 to move, the air cylinder 2 cooperates with the T-shaped rod 6 to drive the moving sleeve 1 to move, so that the position of the moving sleeve 1 is moved away from the bending part of the stirrup 16, one side of the moving sleeve 1 is fixedly connected with a protruding rod 36, both sides of the top and bottom of the fixing seat 7 are fixedly connected with a fixing plate 11 that cooperates with the moving sleeve 1, one side of the fixing plate 11 is provided with a sliding groove 23, the protruding rod 36 is embedded in the sliding groove 23, and the sliding groove 23 cooperates with the protruding rod 36 to adjust the moving trajectory of the moving sleeve 1.

[0026] The middle part of the sliding groove 23 inclines towards the stirrup 16, that is, the extending direction of the middle part of the sliding groove 23 is inclined to the moving direction of the moving sleeve 1. When the moving sleeve 1 moves, it drives the convex rod 36 to move. The inner wall of the inclined section of the sliding groove 23 abuts against the convex rod 36, so that the convex rod 36 drives the moving sleeve 1 to move away from the bending position of the stirrup 16 and then move towards the stirrup 16. The moving sleeve 1 slides axially relative to the corresponding main reinforcement 15, and drives the corresponding main reinforcement 15 to move closer in the radial direction towards the stirrup 16. And the main reinforcement 15 elastically rebounds to form a straight line, so that the main reinforcement 15 is located at the corresponding position on the formed steel reinforcement cage, that is, the main reinforcement 15 contacts the stirrup 16. At this time, the moving sleeve 1 moves away, which is convenient for subsequent welding at the contact position corresponding to the main reinforcement 15 and the stirrup 16. One side of the support seat 19 is provided with an automatic welding robotic arm 22. The number of the automatic welding robotic arms 22 is set to several and is adapted to the arrangement number of the main reinforcements 15. The automatic welding robotic arm 22 welds the welding points after the moving sleeve 1 leaves the bending position of the stirrup 16. Thus, without manual feeding of the stirrup 16, the bending and forming of the stirrup 16 and the welding of the stirrup 16 and the main reinforcement 15 are completed. And the hooks of adjacent stirrups 16 on the formed steel reinforcement cage are staggered from each other, ensuring the forming quality of the steel reinforcement cage, reducing the operation process between the bending and welding of the steel reinforcement cage, and improving the efficiency of the bending and welding of the steel bars.

[0027] Embodiment 2. After the stirrup 16 is fed in the traditional stirrup cage bending and welding equipment, the stirrup 16 loses its limit, and it is easy for the subsequent main reinforcement 15 to be welded to the inclined stirrup 16 in the bent state. Welding under the stress between the main reinforcement 15 and the stirrup 16 results in a reduction in the welding quality of the steel reinforcement cage.

[0028] Such as Figure 1-Figure 6 and Figure 8 , on the basis of Embodiment 1, a magnetic plate 33 is slidably sleeved on one side of the bending plate 5. One side of the bottom of the fixed seat 7 is fixedly connected with a support block 21. A horizontal groove for the stirrup 16 to pass through is opened on one side of the support block 21. The magnetic plate 33 is in a U shape. One side of the magnetic plate 33 is fixedly connected with a tension spring 32. One end of the tension spring 32 is fixedly connected with the bending plate 5. One side of the moving sleeve 1 is fixedly connected with an adjusting plate 12. The tension spring 32 pulls the magnetic plate 33 to extend out of the bending plate 5. When the bending plate 5 rotates to bend the stirrup 16, the adjusting plate 12 pushes the magnetic plate 33 to contract into the bending plate 5. The distance that the adjusting plate 12 pushes the magnetic plate 33 to move is adapted to the diameter of the stirrup 16, ensuring that the stirrup 16 can fit on the outer wall of the moving sleeve 1. After the moving sleeve 1 moves away, the adjusting plate 12 disengages from the magnetic plate 33, and the magnetic plate 33 extends out. The bottom of the support block 21 supports the square stirrup 16 in the direction. The magnetic plate 33 extends out to limit the vertical part of the stirrup 16, preventing the stirrup 16 from tilting before welding, and enabling the stirrup 16 to be welded to the main reinforcement 15 after the position of the moving sleeve 1 is adjusted in the vertical state, further ensuring the welding quality.

[0029] A magnet is arranged in the magnetic plate 33, and the acting force between the magnet and the electromagnet 26 is an attractive force, and the attractive force is greater than the tension of the tension spring 32. An electromagnet 26 corresponding to the position of the magnetic plate 33 is fixedly arranged on one side of the bending plate 5. After welding is completed, the electromagnet 26 starts to drive the magnetic plate 33 to contract, and the pushing mechanism drives the steel cage to move for the next round of bending welding. One side of the sliding groove 23 is inclined to the moving direction of the moving sleeve 1, and the inclination direction is opposite to the inclination direction of the middle part of the sliding groove 23, that is, it is inclined to extend and tilt away from the stirrup 16, so that when the moving sleeve 1 is out of contact with the stirrup 16, it will generate a displacement in the direction away from the stirrup 16, avoiding excessive friction between the moving sleeve 1 and the stirrup 16 causing additional wear of the stirrup 16, and at the same time making room to keep the adjustment plate 12 away from the magnetic plate 33, and the magnetic plate 33 extends to limit the side of the stirrup 16, further ensuring the verticality of the stirrup 16 and ensuring the quality of subsequent welding.

[0030] Embodiment three, as Figure 1-Figure 7 On the basis of the second embodiment, the inner sides of the movable sleeve 1 and the T-shaped rod 6 are both provided with connecting holes 29, and the two connecting holes 29 are connected to each other. A No. 1 airbag 31 is fixedly provided on the inner side of the movable sleeve 1, and the cavity of the No. 1 airbag 31 is connected to the connecting hole 29. The cavity at the bottom of the T-shaped rod 6 in the cylinder 2 is connected to the connecting hole 29. When the movable sleeve 1 is close to the stirrup 16, the T-shaped rod 6 slides relative to the cylinder 2 and moves away from the cylinder 2, and the gas is pressed into the No. 1 airbag 31 through the connecting hole 29, so that the No. 1 airbag 31 expands. When the movable sleeve 1 moves away from the stirrup 16, the No. 1 airbag 31 expands and clamps the corresponding main reinforcement 15, and the extension direction of one side of the sliding groove 23 is the same as the moving direction of the movable sleeve 1, so that the No. 1 airbag 31 clamps and cooperates with the movable sleeve 1 to tension the main reinforcement 15, and cooperates with the clamping mechanism of the pushing mechanism of the bending welding equipment to clamp the other end of the main reinforcement 15. Before welding, the stirrups 16 are in a vertical state to stretch the main reinforcement 15 straight, that is, the main reinforcement 15 is kept straight while avoiding the inclination of the stirrups 16 to affect the straight state of the main reinforcement 15, thereby further improving the quality of subsequent welding.

[0031] Embodiment 4, as Figure 1-Figure 7On the basis of the third embodiment, the width of one side of the movable plate 3 is reduced and the movable seat 4 is slidably sleeved. The movable seat 4 can move relative to the movable plate 3 without separating from the movable plate 3. A rotating ring 13 is rotatably connected to one side of the movable seat 4. An arc plate 25 is fixedly connected to one side of the rotating ring 13. An arc groove 14 adapted to the arc plate 25 is provided on one side of the movable sleeve 1. The body of the arc plate 25 is embedded in the arc groove 14. A connecting plate 10 is fixedly connected to one end of the movable seat 4. The connecting plate 10 is slidably connected to the movable sleeve 1. The movable sleeve 1 cooperates with the connecting plate 10 to drive the movable seat 4 to move synchronously in the radial direction of the sleeve 1. The movable sleeve 1 can only move relative to the movable seat 4 in the axial direction. A first arc block 9 is fixedly connected to one side of the movable sleeve 1. A second air bag 34 is fixedly arranged on the inner side of the first arc block 9. A second arc block 24 is fixedly connected to one side of the arc plate 25. A guide groove 30 is provided on the inner wall of the arc groove 14.

[0032] A guide block 27 is fixedly connected to the outer side of the arc plate 25, and the guide block 27 is embedded in the guide groove 30 with an arc shape in the middle. A connecting mechanism is provided on one side of the movable sleeve 1. Specifically, the connecting mechanism includes a connecting cavity 28 and a connecting hole 35. The connecting cavity 28 is provided on one side of the movable sleeve, and the connecting hole 35 is provided in the No. 1 arc block 9 and the connecting plate 10. The connecting cavity 28 connects the connecting hole 35 with the No. 1 airbag 31, and the connecting hole 35 connects the No. 2 airbag 34 with the connecting cavity 28. The connecting mechanism can also be set as a telescopic hose connecting the No. 1 airbag 31 with the No. 2 airbag 34. When the movable sleeve 1 moves, the arc plate 25 moves in the axial direction relative to the movable sleeve 1, driving the guide block 27 to move in the guide groove 30. The arc segment of the guide block 27 and the guide groove 30 Correspondingly, the guide block 27 drives the arc plate 25 to rotate, and the arc plate 25 drives the second arc block 24 to rotate to the opposite side of the first arc block 9. At this time, the No. 1 air bag 31 and the No. 2 air bag 34, which are connected to each other, expand and respectively fix the two ends of the corresponding main reinforcement 15 to be welded, thereby ensuring the straightness of the main reinforcement 15 and the quality of welding. After the welding is completed, the No. 1 driving mechanism 18 drives the movable sleeve 1 to move the rated distance, so that the No. 2 arc block 24 is reset and the restriction on the main reinforcement 15 is removed. After the pushing mechanism pushes the steel cage to move, the movable sleeve 1 continues to move and drives the main reinforcement 15 to move inward. After the movable sleeve 1 is reset, the No. 2 arc block 24 is reset to avoid the movement of the main reinforcement 15 and the stirrups 16, while ensuring the synchronization of stretching the main reinforcement 15, further improving the quality of welding.
