AI Technical Summary
Existing rolling forming equipment is not convenient for limiting the irregular ring parts during use, which causes the irregular ring parts to wobble and shift in position, affecting the forming effect. In addition, the waste chips on the surface of the high-temperature irregular ring parts are easily rolled back into the surface of the ring parts, resulting in a decrease in quality.
A die for rolling and forming irregularly shaped ring parts for oil and gas equipment was designed, comprising a limiting mechanism and a cleaning mechanism. The limiting mechanism uses components such as a sliding groove, sliding rod, slider, and spring to limit the irregularly shaped ring parts and prevent displacement; the cleaning mechanism uses components such as an air extractor, dust suction pipe, and collection frame to adsorb and collect waste debris, preventing waste debris from affecting the forming quality.
It effectively prevents irregularly shaped rings from shifting during the rolling and expanding process, improving processing accuracy and stability. At the same time, the cleaning mechanism ensures that waste chips do not affect the surface quality of the rings, thus improving the forming effect.

[0024] The present invention will be further described in detail below with reference to embodiments:
[0025] like Figures 1-5 As shown, this utility model provides a rolling forming mold for irregular ring parts for oil and gas equipment, including a ring-binding machine 1.

Side rollers 6 are symmetrically fixedly connected to the left side of the upper end of the ring-binding machine 1. A core roller 7 is fixedly installed in the middle of the upper end of the ring-binding machine 1. A limiting mechanism 8 is provided on the right side of the upper end of the ring-binding machine 1. A cleaning mechanism 9 is provided at the lower end of the ring-binding machine 1. An irregular ring blank 10 is sleeved on the outside of the core roller 7.
[0026] The top of the output rod of the hydraulic cylinder 5 is fixedly installed on the left end of the mounting base 3. The outer walls of the rolling roller 4 and the side roller 6 are in contact with the outer wall of the irregular ring blank 10, and the outer wall of the core roller 7 is in contact with the inner wall of the irregular ring blank 10.
[0027] like Figure 3As shown, the limiting mechanism 8 includes two sets of sliding grooves 81, which are symmetrically arranged at the right upper end of the ring binding machine 1. The inner part of the sliding groove 81 is fixedly installed with a sliding rod 82, and the outer part of the sliding rod 82 is slidably connected with a sliding block 84. The outer part of one side of the sliding rod 82 is sleeved with a spring 83. The upper end of the sliding block 84 is fixedly installed with a connecting rod 85, and the outer part of the connecting rod 85 is rotatably installed with a roller 86. The top end of the connecting rod 85 is fixedly connected with a top plate 87, and the middle part of the top plate 87 is threadedly installed with a screw rod 88. The lower end of the screw rod 88 is rotatably connected with a limiting baffle 89.
[0028] One end of the spring 83 is fixedly connected with the inner wall at the bottom end of the groove 2, and the other end is fixedly connected with one side of the sliding block 84.
[0029] The outer wall of the roller 86 is in contact with the lower end outer wall of the special-shaped ring blank 10.
[0030] In this scheme, the limiting baffle 89 is driven to move up and down by rotating the screw rod 88, so that the limiting baffle 89 is in contact with the upper end of the ring blank 10, and the special-shaped ring is further limited by the limiting baffle 89.
[0031] In this scheme, the limiting structure is used to avoid the adverse effects of position deviation on the rolling expansion forming of the special-shaped ring, effectively guaranteeing the machining precision and quality of the special-shaped ring and improving the stability and reliability of the entire rolling expansion forming process.
[0032] As shown in the figure, Figures 4-5 The cleaning mechanism 9 includes a shunt frame 91, which is fixedly connected with the upper end of the ring binding machine 1 on both sides. The upper and lower inner walls of the shunt frame 91 are fixedly connected with the dust cover 92, and the top end of the shunt frame 91 is fixedly connected with the positioning column 93. The rear end of the shunt frame 91 is fixedly installed with the dust suction pipe 94. The lower end of the ring binding machine 1 is fixedly installed with the collecting frame 95, and the upper and lower inner walls of the collecting frame 95 are fixedly connected with the clamping frame 96. The inner side of the clamping frame 96 is movably installed with the filter screen 97. The left end of the collecting frame 95 is fixedly connected with the connecting pipe 98, and the right lower end of the collecting frame 95 is fixedly connected with the triangular seat 99. The upper end of the triangular seat 99 is fixedly installed with the air extractor 910.
[0033] The lower end of the positioning column 93 is fixedly connected with the upper end of the ring binding machine 1, and the top end of the connecting pipe 98 is fixedly installed with the lower end of the dust suction pipe 94.
[0034] The front end of the collecting frame 95 is hingedly installed with a movable door, and the left end of the air extractor 910 is fixedly connected with the right end of the collecting frame 95.
[0035] In this solution, the collected debris can be filtered by using filter screen 97 to prevent the debris from damaging the vacuum pump 910. By opening the movable door on the collection frame 95, the filter screen 97 can be easily pulled out from the holder 96, making it convenient to clean the debris.
[0036] In this solution, the cleaning structure facilitates the adsorption and transportation of waste debris into the collection frame 95 for collection, thereby avoiding any adverse effects of waste debris on the rolling and forming quality of the irregular ring parts.
[0037] The working principle of the special-shaped ring forming mold for this oil and gas equipment will be explained in detail below.
[0038] like Figures 1-5 As shown, the shaped ring forming mold for oil and gas equipment, when in use, uses an external robotic arm to place the high-temperature shaped ring blank 10 onto the ring-forming machine 1, so that the shaped ring blank 10 is sleeved on the outside of the side wall of the core roller 7, and the bottom of the shaped ring blank 10 contacts the outside of the roller 86. Then, the hydraulic cylinder 5 pushes the mounting base 3 to move the rolling roller 4 downward, so that the outside of the rolling roller 4 contacts the top outer wall of the shaped ring blank 10. At the same time, through the rotation of the rolling roller 4, under the action of extrusion pressure, the shaped ring blank 10 is gradually rolled into shape. Simultaneously, the change in the size of the shaped ring blank 10 will push the roller 86 backward, so that the bottom slider 84 can move backward synchronously on the slide rod 82, which can be used for... Spring 83 compresses the ring, and the rebound effect of spring 83 pushes the slider 84 and roller 86, causing roller 86 to make close contact with the outside of the irregular ring, thus limiting the irregular ring and preventing it from shifting and affecting the forming effect. When the irregular ring blank 10 is rolled and formed, the waste chips on the surface of the ring blank 10 are broken by rolling. At this time, the vacuum pump 910 can be started. The vacuum pump 910 can absorb the broken chips through the connecting pipe 98, the dust suction pipe, the diversion frame 91, and the dust suction hood 92, and can transport the absorbed chips to the collection frame 95 for centralized collection, thereby reducing the accumulation of waste chips on the surface of the ring and the resulting decrease in the quality of the ring.
[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
