Description

Technical Field

[0001] This utility model relates to the field of molding tooling technology, and more specifically, to a molding tooling for a pressure-resistant bracket. Background Technology

[0002] In the production process of compression bracing, steel pipes need to be bent into a curved shape, and then the bent steel pipes are welded together to form the overall shape of the compression bracing. The existing tooling for bending and forming steel pipes mainly consists of a bending assembly set on a bending table. During the forming process, steel pipes are manually inserted one by one into the bending assembly, and then the bending assembly is operated to form the pipes. This processing method requires workers to pick up the steel pipes in the material box one by one and then manually insert them, which is inefficient and restricts the improvement of forming and processing efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a pressure-resistant bracket forming tool to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant bracket forming fixture, including a fixed platform, a bending platform fixedly installed on the fixed platform, a fixed shaft fixedly installed on the fixed platform, a sleeve coaxially rotatably installed on the fixed shaft, a storage box corresponding to the outer side of the inlet of the bending platform, the storage box being fixedly connected to the sleeve so that the sleeve can drive the storage box to reciprocate around the fixed shaft, an ejection port corresponding to the bending assembly is opened on the front side of the bottom of the storage box, a push rod coaxially arranged with the ejection port is slidably installed on the bottom of the storage box, the push rod is connected to a push-in module, and the push-in module is used to push the push rod to reciprocate at the bottom of the storage box.

[0005] As a preferred technical solution of this utility model, a bending assembly is fixedly installed on the bending table. The bending assembly includes two positioning plates and a bending arm. The two positioning plates are fixedly fixed on the bending table, and the bending arm is horizontally rotatably installed on the side of the bending table near the storage box.

[0006] As a preferred embodiment of this utility model, the push-in module includes an air guide channel. An air guide channel is provided inside the fixed shaft. An air inlet pipe communicating with the air guide channel is fixed outside the fixed shaft. The air inlet pipe is used to connect to an air supply device. A first air guide hole is provided through the inner wall of the fixed shaft. An air cylinder coaxially arranged with the push rod is fixed to the rear side of the bottom of the storage box. A piston is coaxially telescopically installed inside the air cylinder. The end of the push rod near the piston passes through the storage box and is fixedly connected to the piston. A sealing cover is fixed to the end of the air cylinder away from the storage box. An air inlet is provided on the sealing cover. A second air guide hole is provided through the inner wall of the sleeve. The first air guide hole and the second air guide hole are correspondingly arranged. The second air guide hole is connected to the air inlet on the sealing cover through a pipe.

[0007] As a preferred embodiment of this utility model, an exhaust groove corresponding to the second air guide hole is also provided on the inner wall of the fixed shaft, and the exhaust groove is connected to the outside.

[0008] As a preferred embodiment of this invention, a rubber pad is fixed to the end of the push rod away from the piston.

[0009] As a preferred embodiment of this utility model, an observation window is provided on the inner wall of the storage box.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By using a horizontally rotatable storage box, the steel pipe to be formed can be pre-loaded into the storage box. When a steel pipe needs to be formed, the storage box is rotated to align with the bending component, and then the pushing module automatically pushes the steel pipe into the bending component. Before forming, the storage box is rotated so that it does not obstruct the bending process of the bending component, thus enabling faster forming of the steel pipe for the pressure support.

[0012] By utilizing a push-in module consisting of an air cylinder, piston, and push rod, the high-pressure gas inside the air cylinder can be automatically injected and discharged during the rotation of the sleeve driven by the storage box. This allows the piston to drive the push rod to automatically push out the steel pipe, resulting in higher efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 6 As shown, this utility model provides a forming fixture for a pressure-resistant bracket, including a fixed platform 1, a bending platform 2 fixedly installed on the fixed platform 1, and a bending assembly fixedly installed on the bending platform 2. The bending assembly includes two positioning plates 3 and a bending arm 4. The two positioning plates 3 are correspondingly fixed on the bending platform 2, and the bending arm 4 is horizontally rotatably installed on the side of the bending platform 2 near the storage box 13. After inserting the steel pipe between the two positioning plates 3, the bending arm 4 is rotated so that the bending arm 4 can compress and bend the exposed part of the steel pipe.

[0022] A fixed shaft 5 is fixedly installed on the fixed platform 1. A sleeve 6 is coaxially rotatably installed on the fixed shaft 5. A storage box 13 is correspondingly provided on the outer side of the entrance of the bending table 2. The storage box 13 is fixedly connected to the sleeve 6 so that the sleeve 6 can drive the storage box 13 to reciprocate around the fixed shaft 5. A push-out port corresponding to the bending component is opened on the front side of the bottom of the storage box 13. A push rod 15 coaxially arranged with the push-out port is slidably installed on the bottom of the storage box 13. The push rod 15 is connected to the push-in module. The push-in module is used to push the push rod 15 to reciprocate at the bottom of the storage box 13.

[0023] The push-in module includes an air guide channel 7, a first air guide hole 8, a second air guide hole 9, a pipe 11, an air cylinder 12, and a piston 14. The air guide channel 7 is opened inside the fixed shaft 5, and an air inlet pipe 16 connected to the air guide channel 7 is fixed outside the fixed shaft 5. The air inlet pipe 16 is used to connect to the air supply device. The first air guide hole 8 is opened through the inner wall of the fixed shaft 5. An air cylinder 12 is fixed on the rear side of the bottom of the storage box 13 and is coaxially arranged with the push rod 15. The piston 14 is coaxially telescopically installed inside the air cylinder 12. The end of the push rod 15 near the piston 14 passes through the storage box 13 and is fixedly connected to the piston 14. A sealing cover is fixed on the end of the air cylinder 12 away from the storage box 13. An air inlet is opened on the sealing cover. The second air guide hole 9 is opened through the inner wall of the sleeve 6. The first air guide hole 8 and the second air guide hole 9 are correspondingly arranged. The second air guide hole 9 is connected to the air inlet on the sealing cover through the pipe 11.

[0024] The inner wall of the fixed shaft 5 is also provided with an exhaust groove 10 corresponding to the second air guide hole 9, and the exhaust groove 10 is connected to the outside. By setting the exhaust groove 10, when the piston 14 needs to be reset, it is not necessary to release the air supply device. As long as the second air guide hole 9 on the sleeve 6 is aligned with the exhaust groove 10 during the rotation, the gas in the air cylinder 12 can be automatically discharged, so that the piston 14 is reset.

[0025] A rubber pad is fixed to the end of the push rod 15 away from the piston 14. The rubber pad can reduce frictional loss between the push rod 15 and the steel tube.

[0026] An observation window is provided on the inner wall of the storage box 13. The observation window can be used to observe the number of remaining steel pipes in the storage box 13 so that they can be added in a timely manner.

[0027] In use, the operator sequentially loads the steel pipes of the compression support to be processed into the discharge box. Since the width of the storage box 13 is approximately equal to the outer diameter of the steel pipe, and the overall length of the discharge box is approximately equal to the length of the steel pipe, the steel pipes can be arranged in a straight line from top to bottom within the storage box 13. When a steel pipe needs to be loaded into the bending assembly on the bending table 2, as shown in the attached... Figure 5 As shown, at this time, the operator rotates the storage box 13 around the fixed shaft 5 until the outlet of the storage box 13 is aligned with the inlet of the bending assembly. At the same time, the storage box 13 will drive the sleeve 6 to rotate synchronously, so that the second air guide hole 9 on the sleeve 6 is aligned with the first air guide hole 8 on the fixed shaft 5. The air supply device will input high-pressure gas into the air cylinder 12 through the air guide channel 7, the second air guide hole 9, the first air guide hole 8, and the pipe 11, thereby pushing the piston 14 in the air cylinder 12. The piston 14 pushes the push rod 15 outward, and the push rod 15 pushes out a steel pipe at the bottom of the storage box 13 into the bending assembly, as shown in the attached figure. Figure 6As shown, the operator then resets the storage box 13 to prevent it from blocking the bending arm 4. At this time, the first air guide hole 8 and the second air guide hole 9 are misaligned. When the second air guide hole 9 passes through the exhaust groove 10 during rotation, the high-pressure gas in the air cylinder 12 will be discharged to the outside through the pipe 11, the second air guide hole 9, and the exhaust channel. At this time, the piston 14 in the air cylinder 12 will automatically reset under the action of the reset spring, thereby driving the push rod 15 to reset. In this way, during the entire bending process, it is not necessary to manually fill the steel pipes one by one, which greatly improves the forming efficiency.
