Steel box girder partition plate reinforcing ring forming device

Abstract

The utility model discloses a steel box girder partition plate reinforcing ring forming device, and belongs to the technical field of steel structure bridge manufacturing, machining and assembling. When in use, the baffle reinforcing plate is placed at a proper position, and then the plate is bent through pushing of the male die. In the process, the feeding wheel starts to rotate, and it is ensured that the plate can move stably. When the male die touches the bottom of the wire cutting control claw, the wire cutting control claw forms a lever with the pin shaft B as the center and starts to rotate. The feeding wheel is pushed to be folded inwards through the lever effect, and therefore thread cutting finishing control is completed. Accurate forming of the steel box girder partition plate reinforcing ring is ensured through the action. And after being touched, the male die gradually exits from the working area, so that the completion of the forming work is marked. The process is efficient and accurate, and benefits from exquisite design and stable operation of the tangent control device.

Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure bridge manufacturing, processing and assembly, and specifically relates to a steel box beam diaphragm reinforcement ring forming device. Background Art

[0002] Each steel bridge is composed of thousands of parts and components, and all of them will go through processes such as plate, cutting, assembly, welding and painting. The shape of each bridge determines the shape of the parts, which are different, and the plates used are all thick plates. In order to increase the strength of the steel box girder or rod, the designer will add partitions at a certain interval inside the steel box girder or rod to form a segmental box with two vertical plates and two cover plates of the box girder or rod to increase the stiffness of the box girder or rod. In order to complete the welding construction inside the box, a round, square or elliptical manhole will be opened at the center of the partition (determined by the design) to facilitate the passage of construction personnel; in this way, the partition itself will have a reduced stiffness due to the opening of the hole. In order to ensure the stiffness of the partition itself, the designer will add plates with a width of 120mm~250mm and a thickness of 10mm~16mm around the shape of the hole to reinforce the hole and maintain the overall stiffness of the partition.

[0003] In order to ensure that the shape of the reinforcement plate is similar to the hole and fits well, the hole shape processing of the reinforcement plate is required.

It cannot meet the company's needs for high-quality, efficient and cost-effective bridge processing.

[0027] 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.

[0028] See also Figure 1-Figure 4The utility model provides a steel box girder diaphragm reinforcement ring forming device, including a tangent control claw 3, a die cover plate 6, a T-shaped reset member 8, a spring guide groove 9, an upper and lower die plate connection plate 11, a die fixing plate 12 and a punch 13;

[0029] Among them, the die cover plate 6 and the die fixing plate 12 are assembled and welded by the spring guide groove 9 and the upper and lower die plate connecting plates 11, the tangent control claw 3 is welded as a whole by the ear plate and the arc plate, and the T-shaped reset part 8 is welded by square iron and round steel.

[0030] Specifically, during use, the partition reinforcement sheet is first placed. When the punch 13 is pushed forward, the sheet is bent and the feed wheel 5 rotates. When the punch 13 touches the bottom of the tangent control claw 3, the tangent control claw 3 forms a lever with the B pin shaft 4 to push the feed wheel 5 inward, complete the tangent trimming control, withdraw the punch 13, and complete the molding work.

[0031] In this embodiment, the thickness of the die cover plate 6 and the die fixing plate 12 are both 20 mm, and are welded and fixed by the upper and lower die plate connecting plates 11. The spatial height after welding of the die cover plate 6 and the die fixing plate 12 is 51 mm. Pin shaft holes 2 are opened on both sides of the die cover plate 6, and an A pin shaft 1 is arranged in the pin shaft hole 2. The spring guide groove 9 is welded by 3 plates. A through hole is opened on the surface of the spring guide groove 9, and a T-shaped reset member 8 is arranged in the through hole. The spring guide groove 9 is welded between the die cover plate 6 and the die fixing plate 12, at the 1 / 2 position of the horizontal center.

[0032] Specifically, the thickness of the die cover plate 6 and the die fixing plate 12 are both 20 mm. The two components are first positioned by the upper and lower die plate connecting plates 11, and then fixed together using welding technology. The space height after welding is 51 mm, which can ensure sufficient space for the molding of the steel box girder partition reinforcement ring. Pin holes 2 are provided on both sides of the die cover plate 6. These pin holes are used to install the A pin 1 to fix the tangent control claw 3. The design of the pin hole 2 allows the tangent control claw 3 to be accurately installed on the die cover plate 6 and ensures its stability and precision. The spring guide groove 9 is welded from three plates, and the shape and size of each plate are precisely calculated and cut to ensure the stability and precision of the overall structure. A through hole is opened on the surface of the spring guide groove 9, and the T-shaped reset member 8 is placed in the through hole and can move along the through hole. This design enables the T-shaped reset member 8 to have good elasticity and reset performance, and can adapt to the molding requirements of steel box girder partition reinforcement rings of different shapes and sizes. The spring guide groove 9 is welded between the die cover plate 6 and the die fixing plate 12, and is located at the 1 / 2 position of the transverse center. The selection of this position can ensure that the spring guide groove 9 can provide sufficient guidance and support for the T-shaped reset member 8, and can also ensure the structural stability and accuracy of the entire device.

[0033] Furthermore, through the above steps, we can obtain a steel box girder diaphragm reinforcement ring forming device with stable structure, high precision, good elasticity and reset performance. This device can be widely used in various occasions requiring high-precision and high-efficiency forming of steel box girder diaphragm reinforcement rings.

[0034] In this embodiment, the punch 13 is cut by a precision CNC blanking cutting machine, and the plate thickness of the punch 13 matches the thickness of the die cover plate 6 and the die fixing plate 12 after welding.

[0035] Specifically, the punch 13 is cut and formed by a precision CNC blanking cutting machine. This cutting method can ensure that the punch 13 has a high precision and smooth surface, so that the shape of the steel box girder diaphragm reinforcement ring can be accurately replicated during the forming process. The plate thickness of the punch 13 matches the thickness of the die cover plate 6 and the die fixing plate 12 after welding. This matching thickness design can ensure that during the forming process, the punch 13 can fit closely with the die cover plate 6 and the die fixing plate 12, thereby forming a high-quality steel box girder diaphragm reinforcement ring. After cutting is completed, the punch 13 also needs to undergo a series of processing and finishing steps to ensure that its size and shape meet the design requirements. These steps may include grinding, polishing, heat treatment, etc., in order to further improve the hardness and durability of the punch 13.

[0036] Furthermore, through the above steps, we can obtain a high-precision, high-quality punch 13 for the forming process of the steel box girder diaphragm reinforcement ring. This punch 13 can significantly improve the efficiency and precision of forming, thereby providing a better foundation for subsequent processing and use.

[0037] In this embodiment, the tangent control claw 3 is cut by a precision CNC blanking cutting machine, and the tangent control claw 3 is welded by an arc plate and two ear plates. The arc plate is 50 mm thick and has a pin hole 2 at one end. The ear plate has a pin hole 2. The pin holes 2 on the two ear plates are coaxial, and the straight end of the ear plate is welded to the arc plate.

[0038] Specifically, the tangent control claw 3 is cut and formed by a precision CNC blanking cutting machine. This cutting method can ensure that the tangent control claw 3 has a high precision and smooth surface, so that the tangent position of the steel box girder partition reinforcement ring can be accurately controlled during the forming process. The tangent control claw 3 is welded by an arc plate and two ear plates. The thickness of the arc plate is 50 mm, and a pin hole 2 is opened at one end for installing the A pin 1 to fix the tangent control claw 3 on the die cover plate 6. The ear plate also has a pin hole 2, and the two pin holes 2 are coaxial to facilitate the installation of the A pin 1. The straight end of the ear plate is welded to the arc plate to form an integral structure to ensure the stability and accuracy of the tangent control claw 3. During the welding process, it is necessary to ensure the position accuracy and welding quality between the arc plate and the ear plate to ensure the overall accuracy and stability of the tangent control claw 3. In addition, it is necessary to perform necessary processing and finishing on the welded tangent control claw 3 to further improve its surface quality and dimensional accuracy.

[0039] Furthermore, through the above steps, we can obtain a high-precision, high-quality tangent control claw 3 for controlling the tangent position of the steel box girder diaphragm reinforcement ring. This tangent control claw 3 can significantly improve the efficiency and accuracy of forming, thereby providing a better foundation for subsequent processing and use.

[0040] In this embodiment, one end of the A pin shaft 1 and the B pin shaft 4 is provided with a pin cap with a protruding diameter of 5 mm.

[0041] In this embodiment, a feed wheel 5 is provided on the tangent control claw 3. The feed wheel 5 is cut by a precision CNC blanking cutting machine. The plate thickness is 50 mm, the wheel diameter is 10 mm larger than the diameter of the arc end of the ear plate, and a pin shaft hole 2 is opened in the center.

[0042] Specifically, a feeding wheel 5 is provided on the tangent control claw 3. The function of the feeding wheel 5 is to assist the steel strip to move stably and smoothly on the tangent control claw 3 to ensure the smooth progress of the forming process. The feeding wheel 5 is also cut and formed by a precision CNC blanking cutting machine. Its plate thickness is 50mm, and the wheel diameter is 10mm larger than the diameter of the arc end of the ear plate. This design can ensure that the feeding wheel 5 can adapt to the arc structure of the ear plate, better fit the surface of the ear plate, and improve the stability and smoothness of feeding. The pin hole 2 opened in the center is used to install the A pin 1 to fix the feeding wheel 5 on the tangent control claw 3. By fixing the A pin 1, the position accuracy and stability of the feeding wheel 5 on the tangent control claw 3 can be ensured, thereby further ensuring the accuracy and efficiency of the forming process. When installing the feeding wheel 5, it is necessary to ensure that it fits tightly with the arc end of the ear plate, and also ensure its matching accuracy with the tangent control claw 3. This can be achieved through precise measurement and adjustment to ensure the structural stability and forming accuracy of the entire device.

[0043] Furthermore, through the above steps, we can obtain a feeding wheel 5 with stable structure and high precision, which is used to assist the steel belt to move stably and smoothly on the tangent control claw 3. This design can further improve the efficiency and precision of the steel box beam diaphragm reinforcement ring forming, and provide a better foundation for subsequent processing and use.

[0044] In this embodiment, a spring 7 is provided on the T-shaped reset member 8, and the spring 7 can push the T-shaped reset member 8. The spring 7 is arranged in the spring guide groove 9, and the round steel passes through the spring 7. The tangent control claw 3 is installed in the pin shaft holes 2 on both sides of the die cover plate 6, and is connected by the A pin shaft 1. The feed wheel 5 is installed on the ear plate, connected by the A pin shaft 1, and the punch 13 is connected to the top pressure source.

[0045] Specifically, a spring 7 is provided on the T-shaped reset member 8, one end of the spring 7 is fixed on the T-shaped reset member 8, and the other end is in contact with the spring guide groove 9. When the round steel passes through the spring 7, the spring 7 is subjected to pressure and elastically deformed. When the round steel passes through the tangent control claw 3 and the feeding wheel 5, the spring 7 is elastically deformed under the pressure, pushing the T-shaped reset member 8 to move toward the round steel. After the round steel completely passes through the tangent control claw 3 and the feeding wheel 5, the spring 7 returns to its original state under the action of elastic force, driving the T-shaped reset member 8 to reset. This design can ensure that the tangent control claw 3 and the feeding wheel 5 always keep in contact with the round steel, thereby stably controlling the movement trajectory of the round steel. The tangent control claw 3 is installed in the pin hole 2 on both sides of the die cover plate 6, and is connected by the A pin 1 to fix the position of the tangent control claw 3. The feeding wheel 5 is also installed on the ear plate and connected by the A pin 1 to ensure the stability and position accuracy of the feeding wheel 5. The punch 13 is connected to the top pressure source, which can provide enough pressure to shape the round steel into the required steel box beam diaphragm reinforcement ring shape. During the forming process, the punch 13 is closely matched with the die cover plate 6 and the die fixing plate 12 to form a closed forming space.

[0046] Furthermore, through the above steps, we can obtain a tangent control device with stable structure and high precision, which is used to control the moving trajectory of round steel during the forming process. This design can further improve the efficiency and precision of the forming of the steel box girder partition reinforcement ring, and provide a better foundation for subsequent processing and use.

[0047] Working principle and use process of the utility model: In the production process of the steel box girder partition reinforcement ring, the tangent control device plays a vital role. First, we place the partition reinforcement sheet in the appropriate position, and then bend the sheet by pushing the punch. In this process, the feed wheel starts to rotate to ensure that the sheet can move stably. When the punch touches the bottom of the tangent control claw, the tangent control claw forms a lever with the B pin as the center and begins to revolve. This lever action pushes the feed wheel inward to complete the tangent trimming control. This action ensures the precise forming of the steel box girder partition reinforcement ring. After the punch completes the touch, it will gradually withdraw from the working area, marking the completion of the forming work. This process is efficient and precise, thanks to the sophisticated design and stable operation of the tangent control device.

[0048] The electronic components and modules used in the content of this utility model can all be parts commonly used in the market that can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs.
