Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, specifically to a flaring device for processing corrosion-resistant rubber hoses. Background Technology
[0002] Corrosion-resistant rubber hoses are widely used in chemical, environmental protection, and petroleum industries due to their excellent resistance to acid and alkali corrosion and chemical media erosion. They are often used to transport corrosive liquids or gases. The quality of their flaring directly affects the sealing, stability, and service life of the pipe connection. During the flaring process, the rubber hose needs to be supported and cooled to ensure processing accuracy and material properties.
[0003] Currently, traditional rubber hose flaring devices mostly use rigid support structures to support the outer wall of the rubber hose, and achieve cooling through simple air cooling or natural cooling. However, for corrosion-resistant rubber hoses, rigid support cannot adapt to the deformation of the rubber hose, which can easily cause surface scratches and damage its corrosion-resistant surface structure. In addition, rigid contact leads to uneven stress distribution, and the lack of dynamic buffer support during flaring can cause the rubber hose to break. Utility Model Content
[0004] The purpose of this utility model is to provide a flaring device for processing corrosion-resistant rubber hoses, including a base and a protective component. The inner wall of the base is slidably connected to the outer wall of the protective component. The protective component includes a housing, and a buffer airbag is fixedly connected to the inner wall of the housing. A water inlet pipe is sleeved on the inner wall of the buffer airbag, and a first water delivery pipe is sleeved on the inner wall of the buffer airbag. The water inlet pipe is connected to an external water cooling circulation system. As cooling water is continuously filled in, the buffer airbag expands outward due to the high temperature resistance and high elasticity of the rubber material, gradually and tightly fitting the outer wall of the rubber hose, so that the buffer airbag wraps around the outer wall of the rubber hose. A tension spring is fixedly connected to the inner wall of the buffer airbag, and the tension spring is arranged in a circular array along the central axis of the buffer airbag. Under the tension of the tension spring, the buffer airbag contracts back to its initial relaxed state.
[0005] Preferably, a first water supply pipe is fitted on the outer wall of the water inlet pipe, a ball valve is fitted on the outer wall of the first water supply pipe, a second water supply pipe is fitted on the inner wall of the ball valve, and a nozzle is fixedly connected to the outer wall of the second water supply pipe.
[0006] Preferably, the first water supply pipe is located on one side of the buffer airbag, the ball valve is located on the other side of the buffer airbag, a series water pipe is fixedly connected to the outer wall of the ball valve, the outer wall of the nozzle is fixedly connected to the outer wall of the housing, and the nozzles are arranged in a circular array along the central axis of the housing. By rotating the ball valve, the cooling water in the buffer airbag is sprayed out through the nozzle to cool the outer wall of the rubber tube.
[0007] Beneficial effects
[0008] This invention provides a flaring device for processing corrosion-resistant rubber hoses. It has the following beneficial effects:
[0009] (I) This flaring device for processing corrosion-resistant rubber tubes, through the flexible water-filled design of the buffer airbag, can adapt to corrosion-resistant rubber tubes of different diameters, avoiding the surface scratches and stress concentration problems caused by traditional rigid supports. During the flaring process, the stable pressure inside the airbag can balance the expansion force of the flaring mold core in real time, and evenly distribute the stress on the rubber tube wall, thereby reducing the rupture rate. It is especially suitable for special corrosion-resistant rubber materials with high hardness and easy cracking, and can improve the product qualification rate.
[0010] (II) The flaring device for processing corrosion-resistant rubber hoses achieves synchronous water cooling by integrating a buffer airbag, water inlet pipe, first water supply pipe, ball valve, second water supply pipe and nozzle. The cooling water can directly remove the heat transferred by the buffer airbag when it comes into contact with the surface of the rubber hose. When the protection of the rubber hose ends, the cooling water in the buffer airbag is sprayed out from the nozzle through the ball valve, which achieves rapid cooling of the outer wall of the rubber hose. Rapid cooling effectively avoids the problem of material aging and deformation of the rubber hose caused by high temperature.
[0011] (III) The sliding connection design between the protection components and the base enables tool-free quick disassembly and assembly. This design not only facilitates equipment maintenance and reduces downtime, but also allows for quick switching of adaptable components for different specifications of rubber tubes, thus meeting the purpose of diverse processing scenarios.

[0017] The present invention will now be described in detail with reference to the accompanying drawings. A flaring device for processing corrosion-resistant rubber hoses includes a base 1 and a protective component 2. The inner wall of the base 1 is slidably connected to the outer wall of the protective component 2. The protective component 2 includes a housing 21. A buffer airbag 22 is fixedly connected to the inner wall of the housing 21. A water inlet pipe 23 is sleeved on the inner wall of the buffer airbag 22. A first water delivery pipe 24 is sleeved on the inner wall of the buffer airbag 22. A tension spring 29 is fixedly connected to the inner wall of the buffer airbag 22, and the tension spring 29 is arranged in a circular array along the central axis of the buffer airbag 22.
[0018] The outer wall of the inlet pipe 23 is fitted with a first water supply pipe 24, the outer wall of the first water supply pipe 24 is fitted with a ball valve 25, the inner wall of the ball valve 25 is fitted with a second water supply pipe 26, and the outer wall of the second water supply pipe 26 is fixedly connected with a nozzle 27.
[0019] The first water supply pipe 24 is located on one side of the buffer airbag 22, the ball valve 25 is located on the other side of the buffer airbag 22, the outer wall of the nozzle 27 is fixedly connected to the series water pipe 28, the outer wall of the nozzle 27 is fixedly connected to the outer wall of the housing 21, and the nozzles 27 are arranged in a ring array along the central axis of the housing 21.
[0020] The flaring device for processing corrosion-resistant rubber hoses mainly consists of a base 1 and a protective component 2. The protective component 2 supports the outer wall of the rubber hose during the flaring process, preventing the rubber hose from cracking and ensuring the smooth progress of the flaring work. Its specific working principle is as follows: First, the base 1 serves as the basic support component of the entire device. The protective component 2 is installed on the base 1 through the shell 21. The water inlet pipe 23 is connected to the external water cooling circulation system.
[0021] Subsequently, the rubber tube to be flared is connected to the conveying equipment, aligning the axis of the rubber tube with the central axis of the device. When the conveying device moves the preheated rubber tube to the work area, the external water cooling circulation equipment is activated. Cooling water flows into the buffer airbag 22 through the inlet pipe 23. As the cooling water is continuously filled, the buffer airbag 22 expands outward due to the high temperature resistance and high elasticity of the rubber material, gradually and tightly adhering to the outer wall of the rubber tube. When the buffer airbag 22 covers the outer wall of the rubber tube, the water cooling circulation equipment automatically stops working. The stable pressure inside the airbag can balance the expansion force of the flaring mold core in real time. Utilizing the flexibility of the buffer airbag 22, the stress on the rubber tube wall is evenly distributed, reducing the rupture rate of the rubber tube and improving the product qualification rate. The cooling water forms a flexible buffer layer inside the buffer airbag 22. When the airbag is subjected to external pressure, friction, or high temperature, the cooling water can disperse the pressure of the buffer airbag 22, preventing the airbag from rupturing locally due to excessive stress or temperature. This ensures the quality of the rubber tube flaring operation and extends the service life of the buffer airbag 22.
[0022] When the flaring operation is completed, the on-site staff rotates the ball valve 25 to allow the cooling water in the buffer airbag 22 to cool the surface of the rubber tube through the first water supply pipe 24, the ball valve 25, the second water supply pipe 26, the nozzle 27, and the series water pipe 28 under the tension of the tension spring 29. This prevents the rubber tube from aging and deforming due to high temperature, and at the same time, it causes the buffer airbag 22 to immediately contract back to its initial relaxed state, which can shorten the feeding and discharging interval and improve processing efficiency.
[0023] When the protection component 2 needs to be repaired or replaced, the sliding connection design between the protection component 2 and the base 1 makes the replacement process simple and convenient, without the need for additional tools. This not only improves the efficiency of equipment maintenance, but also facilitates the quick replacement of the appropriate protection component 2 for different specifications of corrosion-resistant rubber tubes, thus enhancing the versatility and practicality of the device.
