Description

Technical Field

[0001] This utility model relates to the field of impact device technology, specifically to an impact cylinder for preventing flattening. Background Technology

[0002] Currently, in industrial manufacturing and assembly processes, it is often necessary to flatten materials with cavities or hollow structures (such as metal pipes, plastic pipes, or other shell structures) for subsequent welding, sealing, or shaping. However, existing flattening equipment has a relatively simple structure and often uses direct impact to achieve flattening.

[0003] Traditional flattening structures lack a "pre-contact" or "pre-compression" mechanism. At the moment of contact between the pressure head and the object to be flattened, the sudden change in force often leads to uneven force on both sides of the object, resulting in incomplete flattening, skewing, or localized incomplete flattening. In some structures, the connection between the impact block and the transmission mechanism is fixed and cannot be adjusted according to different installation conditions. The equipment has poor adaptability, and the installation and positioning process is complex and unstable, thus affecting the overall flattening accuracy.

[0004] Therefore, it is necessary to design a crush cylinder to prevent crushing and ensure proper sealing in order to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a flattening cylinder to prevent flattening and to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flattening cylinder for preventing flattening, comprising a top box, wherein two symmetrical adjusting plates are slidably arranged inside the top box, and adjusting ports are provided on both sides of the top box; a bidirectional threaded rod is threaded into the interior of the two adjusting plates, and a knob is fixedly connected to one end of the bidirectional threaded rod; two symmetrical first connecting posts are fixedly connected to the bottom of the opposite ends of the two adjusting plates, and a connecting plate is fixedly connected between the two first connecting posts on the same side; multiple fixing posts are fixedly connected to the bottom of the two connecting plates; a flattening cylinder body is fixedly connected to the bottom of the top box, and the flattening cylinder... A lifting plate is fixedly connected to the bottom of the cylinder body, and a striking block is fixedly connected to the bottom of the lifting plate. Multiple second connecting posts are fixedly inserted into the outer surface of the lifting plate. Springs are sleeved on the outer surface of each of the multiple second connecting posts. Limiting plates are fixedly connected to the top of each of the multiple second connecting posts. A receiving plate is fixedly connected to the bottom of the multiple second connecting posts. A pre-contact member is fixedly connected to the bottom of the receiving plate. Four sliding openings are provided on the outer surface of the lifting plate. Insertion ports are provided on both sides of each of the four sliding openings. A sliding block is slidably inserted into the two insertion ports on the same side. The bottom ends of the four first connecting posts are slidably inserted into the four sliding blocks respectively.

[0007] Preferably, there are four springs and four second connecting columns, and both ends of the four springs are fixed to the bottom of the lifting plate and the top of the impact plate.

[0008] Preferably, the adjusting plate is L-shaped, and the horizontal ends of the two adjusting plates are slidably inserted into the interior of the two adjusting ports, and the vertical ends of the two adjusting plates are threaded onto the outer surface of the bidirectional threaded rod, and the two sides of the adjusting plate are respectively in contact with the two sides of the adjusting port.

[0009] Preferably, the impact block is slidably disposed between the four second connecting posts, and the impact block is slidably disposed directly above the impact plate.

[0010] Preferably, the pre-contact is fixed to the bottom of the impact plate, and the material of the pre-contact is nitrile rubber, and the thickness of the pre-contact is 1-2 mm.

[0011] Preferably, the impact plate is made of chromium-molybdenum alloy steel, and the thickness of the impact plate is 10-15mm.

[0012] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0013] This invention achieves automatic alignment and pre-contact buffering during the impact process by setting up a pre-contact component, a limiting structure, and an adjustable connecting mechanism. This effectively avoids problems such as incomplete compaction and misalignment, improving the compaction quality and operational stability. At the same time, the use of nitrile rubber as the pre-contact material and chromium-molybdenum alloy steel as the impact plate material balances elastic absorption and impact resistance, further extending the service life of the device and enhancing its adaptability to different installation positions. The overall structure is reasonable, the impact process is stable and efficient, and it is highly practical. Attached Figure Description

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3This utility model provides a flattening cylinder to prevent flattening, including a top box 1. Two symmetrical adjusting plates 2 are slidably arranged inside the top box 1, and adjusting ports 17 are provided on both sides of the top box 1. A bidirectional threaded rod 14 is threaded into the interior of both adjusting plates 2, and a knob 18 is fixedly connected to one end of the bidirectional threaded rod 14. Two symmetrical first connecting posts 3 are fixedly connected to the bottom of the two adjusting plates 2 at their far ends, and a connecting plate 11 is fixedly connected between the two first connecting posts 3 on the same side. The bottom of both connecting plates 11 is fixedly connected to... Multiple fixed posts 12 are provided. A flattening cylinder body 5 is fixedly connected to the bottom of the top box 1, and a lifting plate 4 is fixedly connected to the bottom of the flattening cylinder body 5. A striking block 8 is fixedly connected to the bottom of the lifting plate 4, and multiple second connecting posts 6 are fixedly inserted into the outer surface of the lifting plate 4. Springs 7 are sleeved on the outer surface of each of the multiple second connecting posts 6, and limit plates 15 are fixedly connected to the top of each of the multiple second connecting posts 6. A receiving plate 9 is fixedly connected to the bottom of the multiple second connecting posts 6, and a pre-contact member 10 is fixedly connected to the bottom of the receiving plate 9. An opening is provided on the outer surface of the lifting plate 4. There are four sliding ports 13, and each of the four sliding ports 13 has an insertion port on both sides. A sliding block 16 is slidably inserted into each of the two insertion ports on the same side. The bottom ends of the four first connecting posts 3 are slidably inserted into the four sliding blocks 16. Through the insertion of multiple fixed insertion posts 12, the device can be stably inserted into the required installation position, ensuring stable operation of the device. Simultaneously, by rotating the knob 18, the spacing between each pair of first connecting posts 3 can be adjusted to adapt to different installation positions. During operation, the expansion of the flattened cylinder body 5 causes the pre-contact member 10 to... The pre-contact component 10 pre-adapts to the impact surface of the object being struck by the pre-contact plate 10 through slight deformation, thus adapting to the stability of the subsequent impact. Then, the lifting plate 4 continues to fall, causing the impact block 8 to gradually reach the pile foundation impact plate 9, flattening the object being struck at the bottom of the pre-contact component 10. During the impact process, the pre-contact component 10 and the impact plate 9 are set to adapt to the impact surface in advance, and the four first connecting columns 3 and the four second connecting columns 6 limit the impact sliding to ensure the accuracy of the impact. This ensures that the problem of incomplete flattening is not likely to occur during the entire flattening process.

[0021] In order to enable the pre-contact component 10 to perform pre-impact work in advance and to elastically contract, there are four springs 7 and four connecting columns 6, and both ends of the four springs 7 are fixed to the bottom of the lifting plate 4 and the top of the impact plate 9.

[0022] To facilitate the adjustment of the spacing between the two adjustment plates 2 inside the top box 1, the adjustment plates 2 are L-shaped, and the horizontal ends of the two adjustment plates 2 are respectively slidably inserted into the interior of the two adjustment ports 17, and the vertical ends of the two adjustment plates 2 are threaded onto the outer surface of the bidirectional threaded rod 14, and the two sides of the adjustment plates 2 are respectively attached to the two sides of the adjustment ports 17.

[0023] In order to ensure stable flattening after the pre-impact, the impact block 8 is slidably disposed between the four second connecting posts 6, and the impact block 8 is slidably disposed directly above the impact plate 9.

[0024] In order to make better contact with the impacted object in advance and adapt to the slight deformation of the object's surface to improve the compaction, the pre-contact member 10 is fixed to the bottom of the impact plate 9, and the material of the pre-contact member 10 is nitrile rubber, and the thickness of the pre-contact member 10 is 1-2mm.

[0025] In order to improve the service life of the impact plate 9 after the impact block 8 impacts the impact plate 9, and to facilitate the transmission of impact force and improve the efficiency of the flattening work, the impact plate 9 is made of chromium-molybdenum alloy steel and the thickness of the impact plate 9 is 10-15mm.
