Description

Technical Field

[0001] The utility model relates to the technical field of stamping processing, in particular to a stamping processing device for mechanical sealing parts. Background Art

[0002] A mechanical seal is a device that prevents fluid leakage by allowing at least one end face perpendicular to the axis of the rotating shaft to remain in contact and slide relative to each other under the action of fluid pressure, the elastic force of a compensation mechanism, and the cooperation of an auxiliary seal. For example, in equipment such as centrifugal pumps, centrifuges, reactors, and compressors, the dynamic ring assembly is the most important in mechanical seals. The dynamic ring assembly consists of a dynamic ring seat, a rubber ring, and a dynamic ring made of silicon carbide. The existing processing of the dynamic ring assembly is mostly to combine the dynamic ring seat, rubber ring, and dynamic ring, and then stamp the dynamic ring to fix the dynamic ring in the dynamic ring seat, so that the three are combined into a whole. During the stamping process, the stamping position needs to be aligned with the positioning groove on the dynamic ring. In the existing processing, most of the operations are done manually, and the position of the dynamic ring needs to be manually adjusted for stamping, which is very labor-intensive and cannot guarantee the stability of the processing effect.

[0003] After searching, China Publication No.: CN208960729U discloses a stamping processing equipment, including a frame, a stamping base, a stamping die, a mounting frame, a cylinder, a stamping head and a clamping device. The stamping base is fixed to the top center of the frame by bolts, the top of the stamping base is provided with a stamping die, and the outside of the stamping die is provided with a clamping device. The top side of the frame is fixed with a mounting frame by welding, the top of the mounting frame is fixed with a cylinder by bolts, and the stamping head is installed at one end of the cylinder, and the outsides of the two screws are respectively sleeved with a first fixing plate and a threaded sleeve, and the screw passes through the first fixing plate, and one end of the screw is movably connected to a third fixing seat through a bearing, and a second fixing seat and a fixing rod are respectively installed on both sides of the threaded sleeve, and a second limiting hole is opened on one side of the second fixing seat. The utility model has the characteristics of strong practicality and high stamping precision.

However, ordinary stamping processing fixing equipment cannot fix dynamic rings and dynamic ring seats of different sizes, thereby performing stable stamping. In view of this, we propose a stamping processing equipment for mechanical seals. Utility Model Content

[0026] See also Figure 1-Figure 4On the basis of embodiment 1, the present invention provides a technical solution: preferably, a clamping mechanism 5 is provided on the upper surface of the base 26, and the clamping mechanism 5 includes an arc-shaped sleeve 51, and the upper surface of the base 26 is fixedly connected to the arc-shaped sleeve 51 in a circumferential array. The inner surface of the arc-shaped sleeve 51 is slidably connected to the arc plate 52, and the arc plate 52 is fixedly connected to one end of the spring 1 53. The upper surface of the base 26 is fixedly connected to the other end of the spring 1 53, and the outer arc surface of the arc plate 52 is provided with an arc groove 54, and the inner surface of the arc groove 54 is slidably connected to a slide plate 55, and the outer arc surface of the slide plate 55 is penetrated by a slide rod 56, and the outer arc surface of the slide rod 56 is sleeved with a spring 2 57, and the left surface of the slide rod 56 is fixedly connected to a fixing claw 58, and the outer arc surface of the arc plate 52 is fixedly connected to the vertical rod 6, and the outer arc surface of the vertical rod 6 is linear An array of slots 7 are provided, and the inner surface of the slots 7 is slidably connected with an arc rod 8, which passes through the arc sleeve 51 and is slidably connected to the arc sleeve 51. A fixed slot 9 is provided on the upper surface of the slide 55, and the inner surface of the fixed slot 9 is slidably connected with a trapezoidal block 10, which is slidably connected to the arc slot 54. The inner surface of the arc slot 54 is provided with trapezoidal slots 11 in a linear array, and the inner surface of the trapezoidal slot 11 is slidably connected to the trapezoidal block 10. Through the mutual cooperation between the trapezoidal slot 11 and the trapezoidal block 10, the slide 55 can be limited to ensure that the slide 55 can drive the slide rod 56 and the fixed claw 58 to move up and down in the arc slot 54. According to the specifications of the dynamic ring, it can be adjusted at will to clamp the dynamic ring. At the same time, after clamping, the trapezoidal block 10 is clamped into the trapezoidal slot 11, thereby ensuring the stability of the slide 55.

[0027] In this embodiment, by setting the arc sleeve 51, arc plate 52, fixed claw 58, and slide rod 56, dynamic rings of different sizes can be fixed to ensure that the dynamic ring is stuck above the dynamic ring seat, and at the same time, it will not affect the stamping when the stamping equipment is stamping.

[0028] Working principle: when it is necessary to stamp the dynamic ring and the dynamic ring seat, after placing the dynamic ring seat on the fixed frame 4, and placing the dynamic ring on the dynamic ring seat, according to the position of the dynamic ring, move the slide plate 55 up and down to ensure that the slide plate 55 drives the slide bar 56 and the fixed claw 58 to be on the same horizontal plane as the dynamic ring, and the slide bar 56 clamps the dynamic ring through the elastic force of the spring 2 57 to ensure that the dynamic ring will not fall due to vibration and other reasons during the movement. In the process of moving up and down, the slide plate 55 will drive the trapezoidal block 10 to move, and the inclined surface of the trapezoidal block 10 is affected by the trapezoidal groove 1 1, it will shrink into the fixed groove 9. When the slide plate 55 is fixed, the trapezoidal clamping block 10 is clamped into the trapezoidal groove 11 to fix the slide plate 55. After the arc rod 8 is pulled out of the clamping groove 7, the stamping equipment is started, and the stamping equipment moves downward to squeeze the arc plate 52, so that the arc plate 52 shrinks into the arc sleeve plate 51, compressing the spring 1 53. After the dynamic ring is completely in contact with the dynamic ring seat, friction occurs between the fixed claw 58 and the dynamic ring, and the upper surface of the arc plate 52 will be parallel to the upper surface of the dynamic ring. The stamping equipment continues to stamp downward to stamp the dynamic ring and the dynamic ring seat.
