Abstract
Description
Technical Field
[0001] This application relates to the field of steel formwork production technology, and more specifically, to a bending structure for steel formwork production and processing. Background Technology
[0002] Steel formwork is a steel formwork used for concrete pouring and shaping. In addition to steel formwork, there are also wooden formwork, plywood formwork, etc. Steel formwork is widely used in construction projects because of its multiple uses and the beautiful shape of the poured concrete. Steel formwork can replace wooden formwork, which significantly reduces the removal of pore water pressure and air bubbles in the concrete pressure compared to traditional formwork such as wood, plywood or steel plates.
[0003] During the production and processing of steel formwork, it needs to be bent. Although the existing technology meets the user's needs to a certain extent, there are still some defects in its use. The specific problems are as follows: the existing bending devices for steel formwork production and processing are inconvenient to control the steel formwork precisely during use, which may increase the inaccuracy of bending during production, thus affecting the product quality and precision.
[0004] To address the aforementioned problems, this application provides a bending structure for steel formwork production and processing. Utility Model Content
[0005] The technical solution provided in this application for a bending structure used in the production and processing of steel formwork is as follows:
[0006] A bending structure for steel formwork production and processing includes a base, an auxiliary mechanism provided on the outer side of the base, and the auxiliary mechanism extending into the interior of the base;
[0007] The auxiliary mechanism includes two fixed plates, both of which are fixedly connected to the top of the base. The two fixed plates are symmetrically arranged about the center line of the base. An electric push rod is fixedly embedded inside each of the two fixed plates. A connecting frame is fixedly connected to the inner end of each of the two electric push rods. A motor is fixedly connected to the front side of each of the two connecting frames. A bidirectional screw is fixedly connected to the output shaft of each of the two motors. Two screw blocks are screwed to the outer wall of each of the two bidirectional screws. Four screw blocks are respectively embedded inside the two connecting frames. A groove is opened on the inner side of each of the four screw blocks. A spring is fixedly embedded inside each of the four grooves. A hollow sleeve is fixedly connected to the inner end of each of the four screw blocks. A connecting rod is fixedly connected to the inner end of each of the four springs. The inner ends of the four connecting rods pass through the four hollow sleeves and are fixedly connected to limit plates. A connecting component is provided on the outer side of each of the four limit plates.
[0008] Furthermore, the two bidirectional screws are movably connected to the two connecting brackets via bearings, and the four connecting rods are respectively matched with the four grooves.
[0009] The above technical solution enables the two bidirectional screws to rotate more stably and securely.
[0010] Furthermore, the connecting component includes a base plate, which is fixedly connected to the top of the base, and a retainer is fixedly connected to the top of the base plate.
[0011] The above technical solution, by setting up a bracket, facilitates the bending operation of the steel formwork in the later stage.
[0012] Furthermore, the top of the card holder is provided with a bending block, and L-shaped plates are fixedly connected to both sides of the bending block.
[0013] The above technical solution, by setting two L-shaped plates, can support and fix the bending block, thus making it more stable when moving up and down.
[0014] Furthermore, a cylinder is fixedly connected to the bottom of each of the two L-shaped plates, and the cylinder is fixedly embedded inside the base.
[0015] The above technical solution, by setting two cylinders, facilitates the subsequent adjustment of the height of the bending plate.
[0016] Furthermore, all four limiting plates are made of polyurethane material, and the four limiting plates are located on the front and rear sides of the card seat and the bending block, respectively.
[0017] The above technical solution reduces friction between the steel template and the four limiting plates because all four limiting plates are made of polyurethane.
[0018] In summary, this application includes the following beneficial technical effects:
[0019] In use, two motors are started, and their output shafts drive two bidirectional screws to rotate, causing the four limit plates to move in opposite directions. Once the four limit plates have moved to the designated positions, two electric push rods are started, causing their telescopic ends to move the two connecting frames in opposite directions, so that the four limit plates contact both sides of the steel template. Then, in conjunction with the connecting components, the steel template is bent. Through this structure, the steel template can be precisely controlled, effectively improving the bending accuracy of the steel template. Attached Figure Description

[0028] Example:
[0029] This application discloses a bending structure for steel formwork production and processing. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 It includes a base 1, an auxiliary mechanism on the outside of the base 1, and the auxiliary mechanism extends into the base 1;
[0030] The auxiliary mechanism includes two fixed plates 2, both of which are fixedly connected to the top of the base 1. The two fixed plates 2 are symmetrically arranged about the center line of the base 1. Electric push rods 3 are fixedly embedded inside the two fixed plates 2. Connecting frames 4 are fixedly connected to the inner ends of the two electric push rods 3. Motors 5 are fixedly connected to the front of the two connecting frames 4. Bidirectional screws 6 are fixedly connected to the output shafts of the two motors 5. Two screw blocks 7 are screwed onto the outer walls of the two bidirectional screws 6. The four screw blocks 7 are respectively embedded inside the two connecting frames 4. Grooves are opened on the inner sides of the four screw blocks 7. Springs 8 are fixedly embedded inside the four grooves. Hollow sleeves 9 are fixedly connected to the inner ends of the four screw blocks 7. Connecting rods 10 are fixedly connected to the inner ends of the four springs 8. The inner ends of the four connecting rods 10 pass through the four hollow sleeves 9 and are fixedly connected to limit plates 11. The connection points between the two bidirectional screws 6 and the two connecting frames 4 are movably connected by bearings. The four connecting rods 10 are matched with the four grooves respectively, which makes the two bidirectional screws 6 more stable and secure when rotating.
[0031] Please see Figure 1 and Figure 2 The four limiting plates 11 are provided with connecting components on their outer sides. The connecting components include a base plate 12, which is fixedly connected to the top of the base 1. A card seat 13 is fixedly connected to the top of the base plate 12. A bending block 14 is provided on the top of the card seat 13. L-shaped plates 15 are fixedly connected to both sides of the bending block 14. By setting the card seat 13, it is convenient to perform bending operations on the steel template later. At the same time, by setting the two L-shaped plates 15, the bending block 14 can be supported and fixed, so that it can move up and down more smoothly.
[0032] Please see Figure 1 and Figure 2 Two L-shaped plates 15 are fixedly connected to the bottom of each cylinder 16, which is fixedly embedded inside the base 1. The four limiting plates 11 are all made of polyurethane material. The four limiting plates 11 are located on the front and rear sides of the card seat 13 and the bending block 14, respectively. By setting two cylinders 16, it is convenient to adjust the height of the bending plate later. At the same time, since the four limiting plates 11 are all made of polyurethane material, it can reduce the friction between the steel template and the four limiting plates 11.
[0033] The implementation principle of this embodiment is as follows: In use, the steel template can be placed between the card seat 13 and the bending block 14. Then, according to the size of the steel template, two motors 5 are started simultaneously. The output shafts of the two motors 5 drive the two bidirectional screws 6 to rotate. Since the outer sides of the four screw blocks 7 are respectively in contact with the inner walls of the two connecting frames 4, the four screw blocks 7 can drive the four limiting plates 11 to move in opposite directions. When the four limiting plates 11 move to the designated position, the two electric push rods 3 are started, so that the extension ends of the two electric push rods 3 drive the two connecting frames 4 to move in opposite directions, so that the four limiting plates 11 contact the two sides of the steel template respectively. At this time, the four springs 8 will be stressed, deformed, and in a compressed state. Then, the two cylinders 16 are started simultaneously, so that the bending block 14 moves vertically downward. The bending block 14 exerts pressure on the steel template to bend it. At the same time, the limiting of the four limiting plates 11 is used to precisely control the steel template, thereby effectively improving the bending accuracy of the steel template.
[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
