Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, and in particular to a molding equipment for double-sided stainless steel composite pipe fittings. Background Technology

[0002] Double-sided stainless steel composite pipe fittings are pipe fittings made of two different metal materials. Usually, a layer of stainless steel is laminated on both the inner and outer surfaces of a carbon steel or other base metal pipe. With stainless steel on both the inner and outer layers, they can effectively resist the erosion of various corrosive media. Whether it is the corrosive liquid transported inside the pipe or the moisture, acid and alkali substances in the external environment, they can provide reliable protection and greatly extend the service life of the pipe fittings.

[0003] Regarding the aforementioned technologies, the existing forming equipment has the following drawbacks: stainless steel composite pipe fittings are composed of an outer layer of stainless steel and an inner layer of substrate. During cutting, the blade applies shearing and frictional forces to the local material. The inner wall at the cutting point is unsupported, and the difference in strength between the high hardness of the outer stainless steel and the inner material can easily lead to local stress concentration. Therefore, this utility model provides a forming equipment for double-sided stainless steel composite pipe fittings. Utility Model Content

[0004] The purpose of this application is to provide a forming device for double-sided stainless steel composite pipe fittings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a forming device for double-sided stainless steel composite pipe fittings, comprising a support plate, a groove on the outer side of the support plate, and a precision support assembly disposed within the groove; the precision support assembly includes a fixed disk disposed within the groove, a rotating disk rotatably connected to the outer side of the fixed disk, multiple gear teeth fixedly connected to the outer side of the rotating disk, multiple guide grooves on the outer side of the rotating disk, a sliding rod slidably connected within the guide grooves, a sliding groove adapted to the sliding rod on the outer side of the fixed disk, a slider fixedly connected to the outer side of the sliding rod, a guide rail adapted to the slider on the inner wall side of the sliding groove, a push rod fixedly connected to one end of the sliding rod, a load-bearing block fixedly connected to one end of the push rod, and a multi-point support assembly disposed within the groove.

[0009] Preferably, a fixing plate adapted to the inner wall side of the groove is fixedly connected to the outer side of the support plate, and multiple slots adapted to the arc plate and the support block are opened on the outer side of the fixing plate.

[0010] Preferably, a hydraulic telescopic rod is provided through the inner side of the fixing plate, and the output end of the hydraulic telescopic rod is fixedly connected to the fixing plate.

[0011] Preferably, a fixing frame is fixedly connected to the outer side of the support plate, and a hydraulic push rod is provided through the inner side of the fixing frame.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] In this invention, the radial force during cutting can be directly offset by the precise support components, preventing the inner wall of the pipe from collapsing due to stress or the outer stainless steel from developing micro-cracks. This ensures the flatness and perpendicularity of the cut surface. Furthermore, the multi-point support components disperse the vibration during cutting throughout the entire pipe, preventing swaying caused by single-point stress and further improving the stability of the pipe during cutting. The support block, composed of multiple stacked honeycomb tubes, assists in heat dissipation and limits the range of thermal deformation, preventing overall dimensional deviations of the pipe due to temperature changes.

The fixing rods 13 are used to connect the fixing ring 10 and the arc plate 12, fixing the arc plate 12 in a designated position. Multiple arc plates 12 are fixedly connected to the outside of the fixing rods 13. Support blocks 11 are fixedly connected to the outside of the arc plates 12. The support blocks 11 directly support the pipe fitting and share the weight of the pipe fitting. The support blocks 11 are composed of multiple stacked honeycomb tubes. The honeycomb tube structure has high strength and light weight, which reduces the overall weight of the equipment and lowers the cost while ensuring the support force. A positioning frame 20 is fixedly connected to the outside of the fixing plate 15. The positioning frame 20 is used to fix the motor 18, ensuring that the motor 18 is accurately positioned so that it can stably drive the gear 19.

The precise control of the rotating plate 16 is achieved by controlling the operation of the motor 18.A gear 19 is fixedly connected to the output end of the motor 18. The gear 19 meshes with the gear teeth 21, transmitting the power of the motor 18 to the rotating disk 16, thus realizing the rotational motion of the rotating disk 16. A connecting rod 14 is fixedly connected to the outer side of the fixed disk 15. The connecting rod 14 is used to connect the fixed disk 15 and the arc plate 12, so that the precision support component and the multi-point support component are interconnected and work together.

[0024] Example 2: Reference Figure 1-4 Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a hydraulic telescopic rod 9 is provided through the inner side of the fixed plate 7. The hydraulic telescopic rod 9 can achieve telescopic movement through hydraulic drive, and its output end is fixedly connected to the fixed plate 15, which can accurately adjust the position of the fixed plate 15 and provide stable positioning support for subsequent processing operations. A fixed frame 3 is fixedly connected to the outer side of the support plate 1, which plays a role in providing stable support and ensuring the stability of the components installed on it. A hydraulic push rod 4 is provided through the inner side of the fixed frame 3. The hydraulic push rod 4 uses hydraulic power as a power source and can provide stable and strong thrust. A push plate 5 is fixedly connected to the output end of the hydraulic push rod 4, which is used to transmit the thrust of the hydraulic push rod 4. A cutting blade 6 is fixedly connected to the output end of the push plate 5. Under the action of the hydraulic push rod 4, the push plate 5 drives the cutting blade 6 to move, and the cutting blade 6 completes the cutting work of the processed material, achieving efficient and precise cutting effect.

[0025] The working principle of this utility model is as follows: The pipe fitting is placed in the groove 2. The hydraulic telescopic rod 9 is controlled to drive the push plate 5 and the rotating disk 16 to move, so that the load-bearing block 23 moves to the position of the pipe fitting to be cut. The motor 18 is controlled to drive the gear 19 to rotate, and the gear teeth 21 drive the rotating disk 16 to rotate. Through the cooperation of the guide groove 22 and the sliding groove 24, multiple sliding rods 25 drive the load-bearing block 23 to move outward, supporting the edge of the pipe fitting to be cut. At the same time, the connecting rod 14 drives multiple fixed rods 13 to move, and the arc plate 12 drives the support block 11 to move into the inside of the pipe fitting. By providing multi-point and multi-faceted support to the inner wall of the pipe fitting, the overall strength of the pipe fitting is strengthened. Multi-point and multi-faceted support can disperse the vibration during the cutting process to the entire pipe fitting, avoiding swaying caused by single-point force. The hydraulic push rod 4 is controlled to drive the push plate 5 and the cutting blade 6 to move downward to cut the pipe fitting.
