Description

Technical Field

[0001] This invention relates to the field of Teflon sealing ring forming equipment technology, specifically to an automatic Teflon sealing ring forming machine. Background Technology

[0002] Teflon sealing rings are sealing devices made of Teflon material, typically used to seal the flow of liquids or gases in pipes, valves, or other equipment. Teflon is a special high-performance material with excellent high-temperature resistance, corrosion resistance, chemical resistance, and low coefficient of friction, thus Teflon sealing rings have good sealing performance and durability. Teflon sealing rings are typically produced by pressing powdered raw materials. This powder pressing process preserves the characteristics and performance of the Teflon sealing rings, ensuring dimensional accuracy and surface smoothness. Furthermore, it improves sealing performance and wear resistance, extending service life. However, current Teflon sealing ring production generally employs a split-type design. This involves first pressing the Teflon sealing rings into a semi-formed state using a semi-forming device, then transferring them to a secondary pressing device for further pressing.

Detailed Implementation

[0026] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0027] See Figures 1 to 10 As shown: An automatic Teflon sealing ring forming machine includes a frame 1, and a first station and a second station arranged along the long side of the frame 1; a filling device 2 is vertically arranged on the frame 1 and located at the first station; a forming device 3 is vertically fixed on the frame 1 and located at the second station, the forming device 3 also includes a transfer table 32 and the transfer table 32 is provided with a first forming cavity 33 for forming the sealing ring; the transfer table 32 is horizontally driven by a first linear actuator 34 arranged at the bottom, so that the transfer table 32 reciprocates between the first station and the second station; a transfer device 4 is horizontally arranged at the discharge port of the forming device 3, and a stamping device 5 is vertically arranged on one side of the transfer device 4 with the feeding end facing the output end of the transfer device 4, for secondary pressurization of the formed sealing ring.

[0028] In operation, when a sealing ring needs to be manufactured, the operator first pours the sealing ring material into the filling device 2. The material then falls under its own weight to the outlet at the bottom of the filling device 2 and enters the first forming cavity 33, thus achieving automatic filling of the sealing ring material. After the automatic filling is complete, the linear reciprocating drive is activated, driving the transfer table 32 from the first station to the second station. When the sealing ring material reaches the second station, the forming device 3 activates, pressurizing the sealing ring component in the first forming cavity 33, setting the sealing ring in a semi-formed state. Once in the semi-formed state, the sealing ring is simultaneously ejected by the forming device 3 and transported towards the transfer device 4. The transfer device 4 then guides the semi-formed sealing ring to the stamping device 5, where it undergoes secondary pressurization to achieve a formed state before being exported.

[0029] See Figure 3 As shown: The filling device 2 includes a first mounting frame 21, a horizontal plate 22, a hopper 23, and a scrubbing ring 24; the horizontal plate 22 is horizontally mounted on one side of the frame 1 via the first mounting frame 21; the hopper 23 is vertically embedded on the horizontal plate 22, and the hopper 23 is a hollow, inverted truncated cone with openings at both ends; the scrubbing ring 24 is coaxially and detachably fixed at the lower end of the hopper 23, and the lower surface of the scrubbing ring 24 is in frictional contact with the transfer table 32.

[0030] In operation, the sealing ring material is filled into the hopper 23 by the operator. When the transfer platform 32 moves to the first station, directly below the hopper 23, driven by the first linear driver 34, the sealing ring material in the hopper 23 will fall into the first forming cavity 33 under its own gravity, thus achieving automatic feeding of the sealing ring material. After feeding, the transfer platform 32 will slide to the second station under the drive of the first linear driver 34 and cooperate with the forming device 3 to pressurize and form it. Since the hopper 23 is in frictional contact with the upper surface of the transfer platform 32 through the sliding contact ring 24, when the transfer platform 32 moves from the first station to the second station under the drive of the first linear driver 34, the discharge port of the hopper 23 will be closed by frictional contact with the upper surface of the transfer platform 32, thus achieving automatic closure of the discharge port of the hopper 23.

[0031] See Figure 3 and Figure 6As shown: The molding device 3 includes a vertical reciprocating drive 31, a first molding head 311, a transfer table 32, a first molding cavity 33, a first linear drive 34, a first guide plate 35, an ejector plate 36, a first lifting module 37, and a first ejector module 38; the vertical reciprocating drive 31 is vertically fixed on the top of the frame 1 with its drive end passing through the frame 1 and vertically facing the ground; the first molding head 311 is coaxially fixed on the output end of the vertical reciprocating drive 31 and has an upper punch at its end for forming a sealing ring; the transfer table 32 is horizontally fixed on the first linear drive via a sliding table 321. On 34, a first forming cavity 33 is formed through the transfer table 32. The first forming cavity 33 is a circular through hole. The first lifting module 37 is fixedly installed vertically on the sliding table 321 and located directly below the transfer table 32. The first lifting module 37 also includes a fixing limiting ring 373 coaxially fixedly installed in the first forming cavity 33. The outer diameter of the fixing limiting ring 373 is smaller than the inner diameter of the first forming cavity 33, and it forms an annular cavity with the first forming cavity 33. A lifting ring 374 is also coaxially slidably installed in the annular cavity. The lifting ring 374 and the annular cavity constitute a lower concave mold for making a sealing ring. The first ejection module 38 is fixedly mounted horizontally on one side of the frame 1 and directly opposite the first forming cavity 33, for ejecting the ejected sealing ring; the ejection plate 36 is mounted vertically across the side of the filling device 2 near the vertical reciprocating driver 31 and near the upper surface of the transfer table 32, and the lower end of the ejection plate 36 is less than the height of the sealing ring from the upper surface of the transfer table 32.

[0032] In operation, since the first forming cavity 33 is a circular through hole, and together with the lifting ring 374 and the annular cavity, it forms a lower die for making a sealing ring; after the lower die is automatically filled by the filling device 2, the lower die carrying the sealing ring material is moved from the first station to the second station under the drive of the first linear driver 34. At this time, the vertical reciprocating driver 31 moves and drives the first forming head 311 at the drive end to move vertically toward the first forming cavity 33, and drives the upper die set at the end of the first forming head 311 to press down into the lower die formed by the lifting ring 374 and the annular cavity, thereby pressing the sealing ring material in the lower die into a semi-finished sealing ring; the upper punch set at the end of the first forming head 311 is a circular punch; and the upper punch set by the lifting ring 374 and the annular cavity forms a lower die for making a sealing ring. The lower die for forming the sealing ring is a circular concave ring. After the sealing ring is extruded into a semi-finished product by the first forming head 311, the semi-finished sealing ring is ejected from the lower die by the first lifting module 37 and then ejected by the first unloading module 38, thus forming a semi-finished sealing ring. The sealing ring ejected by the first unloading module 38 is placed on the transfer table 32. When the transfer table 32 is driven by the first linear driver 34 to move the first forming cavity 33 to the first station, the sealing ring on the transfer table 32 will fall into the first guide plate 35 under the obstruction of the unloading plate 36, and be guided by the first guide plate 35 to be transferred into the transfer device 4. The first linear driver 34 and the vertical reciprocating driver 31 are both lead screw slides, or other drive mechanisms for linear reciprocating sliding.

[0033] See Figure 6 As shown: The first lifting module 37 includes a first lifting cylinder 371, a second mounting bracket 372, a lifting ring 374, and a fixing limiting ring 373; the lifting cylinder 371 is vertically fixed on the sliding table 321 and located directly below the first forming cavity 33; the fixing limiting ring 373 is coaxially fixed in the first forming cavity 33 through the second mounting bracket 372, and the outer diameter of the fixing limiting ring 373 is the same as the inner diameter of the sealing ring; an annular cavity for forming the sealing ring is formed between the outer wall of the fixing limiting ring 373 and the inner wall of the first forming cavity 33; the lifting ring 374 is coaxially fixed on the top of the lifting cylinder 371, and the lifting ring 374 is an annular tube body, which is slidably disposed in the annular cavity.

[0034] In operation, the sealing ring material automatically filled by the filling device 2 is stored in the lower die formed by the lifting ring 374 and the annular cavity to make the sealing ring. When the sealing ring material in the lower die is pressed by the forming device 3 to form a semi-finished sealing ring, an external power source is first connected to drive the lifting cylinder 371 to move. While the output shaft of the lifting cylinder 371 extends, it drives the lifting ring 374 to slide upward inside the annular cavity, thereby ejecting the semi-finished sealing ring located in the annular cavity.

[0035] See Figure 4 As shown: The first ejection module 38 includes a third mounting bracket 381, a first drive cylinder 382 and an ejection block 383; the first drive cylinder 382 is fixedly mounted horizontally on one side of the frame 1 through the third mounting bracket 381, and the drive end of the first drive cylinder 382 is set directly opposite the first forming cavity 33; the ejection block 383 is fixedly mounted on the output end of the first drive cylinder 382.

[0036] In operation, when the semi-formed sealing ring in the annular cavity is pushed out of the annular cavity by the first lifting module 37, the first driving cylinder 382 extends its output shaft and simultaneously drives the ejector block 383 to move, thereby pushing the sealing ring pushed out by the first lifting module 37 away from the lifting end of the first lifting module 37, thus completing the unloading of the semi-formed sealing ring.

[0037] See Figure 7 , Figure 8 and Figure 10 As shown: The transfer device 4 includes a synchronous belt conveyor 41, a first support frame 42, a guide frame 43, a limiting frame 44, an elastic limiting baffle 45, and a feeding module 46; the synchronous belt conveyor 41 is horizontally fixed on the frame 1 via the first support frame 42, with one end of the synchronous belt conveyor 41 being the inlet and the other end being the outlet; the inlet of the synchronous belt conveyor 41 is directly opposite the outlet of the forming device 3; two sets of guide frames 43 are provided, which are arranged opposite to each other on the synchronous belt conveyor 41 and close to the outlet of the synchronous belt conveyor 41. A gap is left between the two sets of guide frames 43, which forms a channel for the conduction of the semi-finished sealing ring; a through hole is also opened in the middle of the guide frame 43, and an elastic limiting baffle 45 is inclinedly fixed at the through hole; a limiting frame 44 is arranged across the two sets of guide frames 43, and a limiting strip is also provided on the lower surface of the limiting frame 44 near the sealing ring, and a limiting platform is provided near the upper surface of the sealing ring; a guide groove 441 is also opened in the middle of the limiting frame 44; the feeding module 46 is arranged parallel to one side of the synchronous belt conveyor 41 along the transmission direction of the synchronous belt conveyor 41, and is used to feed materials toward the stamping device 5 one by one.

[0038] In operation, the semi-finished sealing rings are pressed and formed by the forming device 3 and then fall onto the synchronous belt conveyor 41 under the guidance of the first guide plate 35. Since the unloading plate is triangular, it can gather the sealing rings in the guided state to the middle of the synchronous belt conveyor 41. After the sealing rings fall onto the synchronous belt conveyor 41, they are transported towards the unloading end of the synchronous belt conveyor 41 under the transmission state of the synchronous belt conveyor 41 and the guidance of the limiting frame 44. Since the lower end of the limiting frame 44 is close to the sealing rings, the sealing rings guided by the synchronous belt conveyor 41 and the limiting frame 44 are transported in a non-stacked progressive manner, thereby achieving the effect of feeding them one by one towards the stamping device 5. The elastic limiting baffle 45 is used to intercept the sealing rings and make them stop in the middle of the guide frame 43, waiting for the feeding device to drive the sealing rings one by one towards the stamping device 5.

[0039] See Figure 10 As shown: The feeding module 46 includes a second linear driver 461, a sliding frame 462, a second drive cylinder 463, and a feeding push rod 464; the second linear driver 461 is horizontally arranged on one side of the first linear driver 34 along the long side of the synchronous belt conveyor 41; the second drive cylinder 463 is vertically fixed above the synchronous belt conveyor 41 via the sliding frame 462; the feeding push rod 464 is horizontally fixed at the end of the second drive cylinder 463 along the transmission direction of the second linear driver 461.

[0040] In operation, the sealing rings transmitted by the synchronous belt conveyor 41 remain in the middle of the guide frame 43 due to the interception of the elastic limit baffle 45. When it is necessary to feed the sealing rings towards the stamping device 5 one by one, firstly, an external power supply is connected to drive the second linear actuator 461 to operate. The second linear actuator 461 drives the sliding frame 462 to move while simultaneously driving the second drive cylinder 463 to slide. During the sliding process of the second drive cylinder 463, the output shaft of the second drive cylinder 463 is set in a retracted state, so that the feeding end of the feeding push rod 464 is away from the sealing ring. After the second drive cylinder 463 slides to the unloading station, the output shaft of the second drive cylinder 463 extends so that the feeding end of the feeding push rod 464 is placed inside the sealing ring, and the feeding push rod 464 is in a downward posture to push the sealing ring towards the stamping device 5 until it is delivered to the stamping station of the stamping device 5. Then, under the drive of the second drive cylinder 463, the feeding push rod 464 is lifted again and slides towards the feeding point. This process is repeated to achieve the effect of feeding one by one. The feeding push rod 464 is L-shaped, with its long rod end being an extension rod and its short rod section being an unloading rod.

[0041] See Figure 9As shown: The stamping device 5 includes a second support frame 51, a stamping cylinder 52, a stamping table 53, a second forming head 54, and a second lifting module 55; the stamping cylinder 52 is vertically fixed on the frame 1 via the second support frame 51; the second forming head 54 is coaxially fixed on the stamping end of the stamping cylinder 52, and the second forming head 54 and the first forming head 311 have the same structure; the stamping table 53 is fixedly installed on the frame 1 and located directly below the stamping cylinder 52, and the stamping table 53 also has a second forming cavity 59 for forming the sealing ring and a guide groove opened near the transfer device 4 and communicating with the second forming cavity 59; the second lifting module 55 is vertically fixed on the frame 1 and located directly below the stamping table 53, and the lifting end of the second lifting module 55 is placed in the second forming cavity 59 to eject the formed sealing ring; the second lifting module 55 and the first lifting module 311 have the same structure.

[0042] In operation, when the semi-formed sealing ring needs to be stamped, the semi-formed sealing ring is fed into the second forming cavity 59 one by one under the drive of the transfer device 4. After the semi-formed sealing ring is fed into the second forming cavity 59, the stamping cylinder 52 extends its output shaft and simultaneously drives the second forming head 54 to be set vertically towards the inside of the second forming cavity 59. The lower punch set at the end of the second forming head 54 and the lower die formed by the second forming cavity 59 and the lifting end of the second lifting module 55 apply secondary pressure to the semi-finished sealing ring until the sealing ring is pressed into a finished product.

[0043] See Figure 10 As shown: A high-pressure air duct 56 and a fixed seat 563 are also provided on one side of the stamping table 53; the high-pressure air duct 56 is fixed in a vertical state on the side of the stamping table 53 near the transfer device 4 through the fixed seat 563 and is inclined towards the stamping station; the high-pressure air duct 56 is provided with a first high-pressure air nozzle 561 and a second high-pressure air nozzle 562, and the first high-pressure air nozzle 561 and the second high-pressure air nozzle 562 are respectively directed towards the end of the second forming head 54 and the second forming cavity 59.

[0044] In operation, since the first high-pressure nozzle 561 and the second high-pressure nozzle 562 are respectively positioned towards the end of the second forming head 54 and the second forming cavity 59, when the second forming head 54 is lifted from inside the second forming cavity 59, regardless of whether the sealing ring is stuck to the end of the second forming head 54 or inside the second forming cavity 59, the first high-pressure nozzle 561 and the second high-pressure nozzle 562 can blow material onto the stuck sealing ring, thereby achieving the unloading operation.

[0045] See Figure 2 As shown: On the other side of the stamping table 53 away from the transfer device 4, there is also a second guide plate 57 and a collection box 58 located directly below the second guide plate 57.

[0046] The second guide plate 57 is used to receive the sealing rings blown off from the stamping end of the stamping device 5 through the high-pressure air pipe 56, and the collection box 58 is used to collect the sealing rings collected by the second guide plate 57.

[0047] This invention enables fully automated processing and production of Teflon sealing rings, eliminating the need for turnover, resulting in high production efficiency and excellent performance.
