Description
Technical Field

[0002] A flaring device is a widely used piece of equipment in industrial production. It is typically used to flare tubular materials such as steel pipes to meet specific connection or assembly requirements.
[0003] However, traditional flaring devices have certain limitations in their operation. These devices typically clamp the steel pipe at one end while relying on a press to push a pin at the other end to flare the pipe. This operation mode not only requires simultaneous clamping and pushing actions, making the process cumbersome and complex, but the design of the clamping device also increases the difficulty of disassembling and removing the steel pipe, reducing overall work efficiency. Furthermore, traditional flaring devices generate significant noise during operation, negatively impacting the working environment and the physical and mental health of operators. To effectively address these challenges, a flaring device for a press is proposed. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0037] Please see Figure 1-7 A flaring device for a press includes a flaring body 1 and a pushing component 2. The upper end of the flaring body 1 is provided with a guide groove 11 and a sliding groove 12 that are connected to each other. The pushing component 2 passes through the flaring body 1 and is perpendicularly connected to the sliding groove 12. Two clamping blocks 3 for clamping steel pipes are symmetrically embedded in the guide groove 11. A flaring groove 34 is provided at one end of the clamping block 3 near the sliding groove 12. A transmission component 4 is slidably arranged in the sliding groove 12. Anti-detachment components 5 are provided on both sides of the sliding groove 12.
[0038] The transmission assembly 4 includes a zigzag block 41 that slides in the slide groove 12 and a transmission plate 42. The transmission plate 42 is located inside the zigzag block 41 and its upper end is rotatably connected to the zigzag block 41. The transmission plate 42 is located between the pushing assembly 2 and the two clamping blocks 3.
[0039] A set of anti-detachment components 5 includes a baffle 51 located on the upper surface of the flaring body 1, a spring 52 located inside the slide groove 12, and a bolt 53. The upper end of the spring 52 abuts against the bottom of the baffle 51, and the lower end abuts against the side structure of the Z-shaped block 41. The bolt 53 passes through the baffle 51 and is fixed to the flaring body 1.
[0040] It should be noted that when flaring the steel pipe, the push assembly 2 pushes the transmission plate 42, which rises under the push of the push assembly 2. At the same time, the rising transmission plate 42 drives the Z-shaped block 41 to rise, causing the Z-shaped block 41 to compress the spring 52. At this time, the transmission plate 42 provides a push for the clamping block 3 under the action of the spring 52. The clamping block 3 clamps the steel pipe under the special structure of the guide groove 11. At the same time, due to the rise of the Z-shaped block 41 and the baffle 51, the push assembly 2 can cooperate with the steel pipe clamped between the clamping blocks 3 to flare the pipe.
[0041] Please see Figure 4 In this embodiment, the pressing assembly 2 includes a pin 21 for flaring the steel pipe and a push rod 22 for connecting an external press. The pin 21 and the push rod 22 are threadedly connected.
[0042] It should be noted that the pressing assembly 2 consists of a ejector pin 21 and a push rod 22. The ejector pin 21 is used to directly flare the steel pipe, while the push rod 22 is connected to an external press to provide the necessary thrust. The ejector pin 21 and the push rod 22 are connected by threads. This design not only facilitates installation and disassembly but also ensures a secure connection between the two, preventing loosening or detachment under high pressure.
[0043] It should be further explained that a sealing ring is added to the side of the ejector pin 21 to reduce the noise of the pushing assembly 2 during operation. At the same time, the ejector pin 21 is also provided with a slot 32 (not shown in the figure) for cooperating with the wrench to rotate the ejector pin 21, which facilitates the disassembly, installation or maintenance of the ejector pin 21.
[0044] In this embodiment, the ejector pin 21 is located inside the flaring body 1, and the side wall of the flaring body 1 is provided with a silencer tube 13 that is sleeved with the push rod 22.
[0045] It should be noted that the main function of the silencer tube 13 is to reduce the noise generated by the push rod 22 during operation. The silencer tube 13 may be filled with sound-absorbing material or adopt a special acoustic structure design to effectively absorb and isolate noise, creating a quieter and more comfortable working environment for the operator.
[0046] Please see Figure 6 In some embodiments, the transmission plate 42 has an inclined surface 421 that cooperates with the ejector pin 21 on the side that is close to the ejector pin 21. The top of the inclined surface 421 is higher than the axis of the ejector pin 21. The guide groove 11 has an isosceles trapezoidal structure and is used to symmetrically guide the two clamping blocks 3 to move towards each other to clamp the steel pipe under the push of the pushing component 2.
[0047] It should be noted that the design of the inclined surface 421 on the transmission plate 42 is key to the automatic clamping of the steel pipe by the clamping block 3. When the ejector pin 21 moves forward, it gradually contacts the inclined surface 421 and pushes the transmission plate 42 to rotate. The thrust of the ejector pin 21 is partially converted into a thrust perpendicular to the clamping block 3. At the same time, due to the isosceles trapezoidal structure design of the guide groove 11, the clamping block 3 can move smoothly and stably towards the center when subjected to thrust, thereby achieving stable clamping of the steel pipe and ensuring that the steel pipe remains horizontal during clamping, avoiding shaking or displacement during the flaring process. Due to the design of the inclined surface 421, part of the thrust of the ejector pin 21 is also converted into an upward vertical force, so that when the clamping block 3 cannot move, the Z-shaped block 41 moves upward, making room for the flaring of the pushing assembly 2.
[0048] Please see Figure 5 In this embodiment, the clamping parts of the opposite sides of the two clamping blocks 3 are provided with spiral teeth 33, and the non-clamping parts are provided with mutually cooperating protrusions 31 and slots 32.
[0049] It should be noted that the clamping parts on opposite sides of the clamping blocks 3 are provided with spiral teeth 33. This design can increase the friction between the clamping blocks 3 and the steel pipe, thereby improving the clamping force. At the same time, the protrusions 31 and slots 32 provided on the non-clamping parts facilitate the quick positioning and fixing of the clamping blocks 3 during disassembly and replacement, and also facilitate the simultaneous movement of the two clamping blocks 3 towards each other.
[0050] In this embodiment, the four corners of the bottom surface of the flaring body 1 are provided with positioning feet 7, and a shock-absorbing sponge block 6 is added to the middle of the bottom surface.
[0051] It should be noted that the positioning feet 7 at the four corners of the bottom surface ensure the stability of the device during operation and prevent the flaring accuracy from being affected by shaking or tilting. The shock-absorbing sponge block 6 added in the middle of the bottom surface can effectively absorb the vibration and impact generated during the flaring process, protecting the device and the working environment from damage.
[0052] Please see Figure 7 In this embodiment, the bottom of the baffle 51 is embedded in the groove 12, and the extensions on both sides cover the edge of the groove 12 to limit the displacement of the spring 52.
[0053] It should be noted that this design can limit the displacement of the spring 52 in the slide groove 12, ensuring that the spring 52 is always inside the slide groove 12. At the same time, the baffle 51 is fixedly connected to the flaring body 1 by bolts 53, which further enhances the stability and reliability of the entire device.
[0054] It should be further explained that, under the action of the spring 52, the Z-shaped block 41 that slides along the slide groove 12 will be located at the bottom of the slide groove 12 when not in operation, which facilitates the reset of the transmission component 4 so as to facilitate the next flaring cycle.
[0055] In summary, this flaring device for the press, through the innovative design of the guide groove 11 and slide 12, combined with the ingenious use of the transmission component 4 and the anti-detachment component 5, achieves stable clamping and efficient flaring of the steel pipe, greatly simplifying the operation process and improving work efficiency. At the same time, the silencer tube 13 design in the pushing component 2 effectively reduces operating noise, providing operators with a more comfortable working environment.
[0056] The flaring device used in this press further enhances the clamping force and ensures flaring accuracy through the cooperation of the spiral clamping teeth 33 and the protrusions 31 and grooves 32. The addition of bottom positioning feet 7 and shock-absorbing sponge blocks 6 improves the stability and safety of the device, ensuring the smooth operation of the production process.
[0057] Please see Figure 8-10 The diagram below shows the device in different operating states. The working principle is as follows:
[0058] When it is necessary to flare the steel pipe, first place the flaring device of the press in a suitable working position, and ensure that the positioning feet 7 at the four corners of the bottom are firmly supported on the ground or assembled on other fixed structures to prevent the device from shaking or tilting during operation.
[0059] Next, place the steel pipe to be flared between the two clamping blocks 3, and place the two clamping blocks 3 in the guide groove 11. At this time, the clamping blocks 3 are in a loose state because they are not subjected to external force, and the steel pipe can be freely placed in the clamping blocks 3.
[0060] Then, the external press is started, and a thrust is applied to the ejector pin 21 through the push rod 22. As the push rod 22 pushes the ejector pin 21 forward, it first contacts the inclined surface 421 on the transmission plate 42. Due to the design of the inclined surface 421, the thrust of the ejector pin 21 is converted into a thrust perpendicular to the clamping blocks 3. Under the guidance of the isosceles trapezoidal structure of the guide groove 11, the two clamping blocks 3 move smoothly and stably toward the center and gradually tighten the steel pipe.
[0061] When the clamping block 3 tightens the steel pipe, the clamping block 3 can no longer be pushed forward. At this time, the spring 52 will be compressed, which will push the transmission plate 42 and the Z-shaped block 41 to move upward in the slide groove 12, making room for the ejector pin 21 to flare, so as to carry out the flaring operation. When the flaring operation is carried out, the flaring groove 34 and the ejector pin 21 cooperate with each other to realize the squeezing and flaring of the steel pipe.
[0062] After the flaring is completed, the external press stops applying pressure. At this time, the spring 52 pushes the Z-shaped block 41 downward under the action of its elastic force, causing the transmission plate 42 to return to its original position. At the same time, the clamping block 3 gradually loosens the steel pipe under the action of the guide groove 11, making it easier to remove the flared steel pipe.
[0063] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
