Description

Technical Field

[0001] The present invention belongs to the technical field of seals, and particularly relates to a processing method for high-precision seals for a water control system. Background Art

[0002] A water control system is a system that controls the amount of water through an online water controller or an offline water controller. The water control system includes pipes for transportation, and rubber rings for sealing are arranged inside the pipes. There are two processing methods for rubber rings, namely molded forming and bonded forming. Molded forming is to first obtain a rubber ring with a regular cross-section through a cutting method, and then extrude the rubber ring through a mold so that the cross-section of the rubber ring becomes the required shape; Bonded forming is to directly extrude the raw material into a rubber strip with the required cross-sectional shape, then perform fixed-length cutting on the rubber strip, and finally bond the two ends of the cut rubber strip. It is generally applicable to the manufacture of rubber strips with larger volumes.

[0003] During the bonding process of the two ends of the rubber strip formed by bonded forming, dislocation is likely to occur, resulting in misalignment at the edges of the rubber strip and affecting the sealing performance of the rubber strip; during the gluing process, it is difficult to keep the amount of glue between the two end faces of the rubber strip uniform. It is easy to have a situation where there is too much glue in some areas causing the adhesive to overflow, and too little glue in some areas causing voids. Refer to Figure 9 , and too much or too little glue in the same area will also affect the sealing performance of the rubber strip. Summary of the Invention

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: A processing method for high-precision seals for a water control system includes the following steps:

[0005] Step 1, extrusion molding: Melting the sealant raw material and then extruding it into a continuous rubber strip.

[0006] Step 2, fixed-length cutting: Cutting the continuous rubber strip to obtain rubber segments with the same length.

[0007] Step 3, bonding into a ring: Bonding the two ends of the rubber segments together with an adhesive to obtain a rubber ring.

[0008] Among them, Step 3 is completed by cooperating with a rubber ring forming device. The rubber ring forming device includes a strip-shaped first frame and a strip-shaped second frame. The first frame is located below the second frame and both are in a horizontal state; the first frame is fixedly installed above the base through a first bracket, and a top plate located above the second frame is fixedly installed on the base through a second bracket. A cylinder is vertically fixedly installed on the bottom surface of the top plate, and the second frame is fixedly connected to the bottom end of the telescopic section of the cylinder; when the top surface of the first frame and the bottom surface of the second frame are in contact, a semi-closed cavity with both ends open is formed between them; a glue supply mechanism is installed on the second frame, and a glue inlet cooperating with the glue supply mechanism is opened on the second frame; a positioning mechanism is installed on the first frame at a position corresponding to the glue inlet.

[0009] As a preferred technical solution of the present invention, the glue supply mechanism includes a glue storage box fixedly installed on the upper surface of the second frame body, and a glue spraying head is installed on the bottom surface of the glue storage box and communicates with the inside of the glue storage box and extends into the glue inlet.

[0010] As a preferred technical solution of the present invention, the positioning mechanism includes two positioning plates horizontally penetrating through the side wall of the first frame body in a sliding fit manner. The positioning plates are in a vertical state and are perpendicular to the length direction of the first frame body; the end face of the positioning plate located inside the first frame body is flush with the inner wall of the first frame body; a translation plate is fixedly installed on the end face of the positioning plate located outside the first frame body, and a bidirectional elastic telescopic rod is fixedly connected between the two translation plates.

[0011] As a preferred technical solution of the present invention, an electric slider is slidably installed on the upper surface of the base and is located between the two translation plates. The end face of the electric slider facing the translation plate is matched with the translation plate; and the edge on one side of the end face of the electric slider facing the translation plate is rounded, and the edge on one side of the surface of the translation plate facing the electric slider is also rounded.

[0012] As a preferred technical solution of the present invention, the glue supply mechanism includes a lifting rod vertically penetrating through the second frame body in a sliding fit manner. A glue leveling plate is fixedly installed at the bottom end of the lifting rod and is matched with the inner wall of the second frame body. The glue leveling plate has the same width as the positioning plate and the end faces of the two facing the port of the second frame body are flush; a lifting platform is fixedly installed at the top end of the lifting rod, and a telescopic spring sleeved on the lifting rod is fixedly connected between the lifting platform and the upper surface of the second frame body.

[0013] As a preferred technical solution of the present invention, a roller is rotatably installed on the lifting platform. A motor seat is fixedly installed on the upper surface of the second frame body, and a motor is fixedly installed on the motor seat. A special-shaped cam corresponding to the position of the roller is fixedly installed on the output shaft of the motor; the special-shaped cam includes a plurality of convex blocks uniformly arranged on its edge along its circumference, and the distance from the top of each convex block to the center of the special-shaped cam is different.

[0014] As a preferred technical solution of the present invention, a horizontal groove is opened on the side wall of the glue inlet. A glue cutting mechanism is installed on the second frame body. The glue cutting mechanism includes a knife seat horizontally slidably installed in the horizontal groove. A cutting knife is fixedly installed on the end face of the knife seat facing the horizontal groove; the surfaces of the knife seat and the cutting knife are both flush with the inner wall of the second frame body; an L-shaped translation frame is horizontally slidably installed on the second frame body, the end of the horizontal section of the translation frame is fixedly connected to the knife seat, and a horizontal elastic telescopic plate is fixedly connected between the vertical section of the translation frame and the second frame body.

[0015] As a preferred technical solution of the present invention, a pressure ring is vertically and slidably fitted in the glue inlet. A pressure rod is vertically and fixedly installed on the upper surface of the pressure ring. A pressure piece is fixedly installed at the top end of the pressure rod. An elastic piece is fixedly connected between the pressure piece and the second frame body.

[0016] The present invention has at least the following beneficial effects: (1) Before gluing, the distance between the two end faces of the rubber strip is limited by the positioning plate, so that the distance between the two end faces of the rubber strip is constant. On the one hand, it ensures a constant glue layer thickness, and at the same time avoids the situation of misalignment at both ends of the rubber strip, improving the sealing performance of the rubber strip; during the gluing process, the two ends of the rubber strip are limited by the cooperation of the first frame body and the second frame body, ensuring that the edges at both ends of the rubber strip are always flush, further improving the sealing performance of the rubber strip.

[0017] (2) During the gluing process of the present invention, a semi-closed glue filling area with an open top is jointly formed by the two end faces of the rubber strip, the positioning plate, the first frame body and the second frame body. The edge of this area is flush with the edge of the rubber strip. After filling the glue into this area through the glue supply mechanism, the edge of the formed glue layer is flush with the edge of the rubber strip, avoiding the situation of adhesive overflow or incomplete filling; during the filling process of the glue supply mechanism, the glue leveling plate continuously rises and falls. During the downward movement of the glue leveling plate, the glue layer is pressed and leveled, promoting the flow of the adhesive and helping the adhesive to fully fill into the glue filling area.

[0018] (3) In actual production, if the amount of glue supplied is exactly equal to the volume of the glue filling area, then the surface of the glue layer corresponding to the glue inlet is likely to be uneven, affecting the sealing performance of the rubber strip; the glue supply mechanism of the present invention supplies slightly more glue each time than the volume of the glue filling area, so that part of the adhesive overflows into the glue inlet, and the excess adhesive is cut off by the glue cutting mechanism to ensure that the surface of the glue layer corresponding to the glue inlet is flat, ensuring the sealing performance of the rubber strip.

[0030] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0031] As Figure 1 shown, this embodiment provides a processing method for a high-precision seal for a water control system, including the following steps:

[0032] Step 1. Extrusion molding: melting the sealant raw material and then extruding it to form a continuous rubber strip.

[0033] Step 2. Fixed-length cutting: cutting the continuous rubber strip to obtain rubber segments of the same length.

[0034] Step 3. Bonding into a circle: bonding the two ends of the rubber segments together with an adhesive to obtain a rubber ring.

[0035] It should be noted that this embodiment is directed to rubber segments with a T-shaped cross-section.

[0036] Among them, Step 3 is completed by using a rubber ring forming device, such asFigure 2 and Figure 6 As shown in Figure 6 , the rubber ring forming device includes a strip-shaped first frame body 1 and a strip-shaped second frame body 2. The first frame body 1 is located below the second frame body 2 and both are in a horizontal state. The first frame body 1 is fixedly installed above the base 3 through a first bracket, and a top plate 4 located above the second frame body 2 is fixedly installed on the base 3 through a second bracket. A cylinder 5 is vertically fixedly installed on the bottom surface of the top plate 4, and the second frame body 2 is fixedly connected to the bottom end of the telescopic section of the cylinder 5. When the top surface of the first frame body 1 is in contact with the bottom surface of the second frame body 2, a semi-closed cavity with openings at both ends is formed between them. A glue supply mechanism 6 is installed on the second frame body 2, and a glue inlet 201 cooperating with the glue supply mechanism 6 is provided on the second frame body 2.

[0037] The inner wall of the semi-closed cavity cooperates with the surface of the rubber section. In the initial state, the second frame body 2 is at the high point position and the cylinder 5 is in a contracted state. After manually inserting both ends of the rubber section into the first frame body 1 from both ends of the first frame body 1, the second frame body 2 is driven by the cylinder 5 to descend until the lower surface of the second frame body 2 is in contact with the surface of the rubber section. The rubber section is limited by the first frame body 1 and the second frame body 2 so that the side walls at both ends of the rubber section are flush. In this state, there is a certain gap between the two end faces of the rubber section, which is used for filling glue, and this gap corresponds to the position of the glue inlet 201. It should be noted that relying solely on the above structure cannot ensure that the gap between the two end faces of the rubber section corresponds to the position of the glue inlet 201.

[0038] As Figure 4 、 Figure 6 and Figure 7 As shown in Figure 4 , Figure 6 , and Figure 7 , a positioning mechanism 7 is installed on the first frame body 1 at the position corresponding to the glue inlet 201. The positioning mechanism 7 includes two positioning plates 701 horizontally penetrating the side wall of the first frame body 1 in a sliding fit manner. The positioning plates 701 correspond to the position of the glue inlet 201. The positioning plates 701 are in a vertical state and are perpendicular to the length direction of the first frame body 1. The end face of the positioning plate 701 located inside the first frame body 1 is flush with the inner wall of the first frame body 1. A translation plate 702 is fixedly installed on the end face of the positioning plate 701 located outside the first frame body 1, and a bidirectional elastic telescopic rod 703 is fixedly connected between the two translation plates 702. An electric slider 704 is slidably installed on the upper surface of the base 3 between the two translation plates 702, and the end face of the electric slider 704 facing the translation plate 702 cooperates with the translation plate 702. And the edge on one side of the end face of the electric slider 704 facing the translation plate 702 is rounded, and the edge on one side of the surface of the translation plate 702 facing the electric slider 704 is rounded.

[0039] The position of the positioning plate 701 in the initial state is as shown in

[0039] Figure 7As shown, part of the positioning plate 701 is located inside the first housing 1; during the process of manually inserting both ends of the rubber segment into the first housing 1 from both ends of the first housing 1 respectively, both ends of the rubber segment gradually approach the positioning plate 701 until both end faces of the rubber segment are in contact with the positioning plate 701. Since the position of the positioning plate 701 corresponds to that of the glue inlet 201, the gap between both end faces of the rubber segment also corresponds to the glue inlet 201, and the gap between both end faces of the rubber segment is the glue filling area; at this point, the positioning plate 701 completes its positioning function. However, since a part of the positioning plate 701 is still located inside the first housing 1, if glue is directly applied to the glue filling area, the surface of the obtained glue layer will not be flush with the surface of the rubber segment, resulting in a decrease in the sealing performance of the rubber ring. Therefore, it is necessary to move the electric slider 704 so that the electric slider 704 pushes the two translation plates 702 to move horizontally in opposite directions. The two translation plates 702 also drive the two positioning plates 701 to move horizontally in opposite directions, and both ends of the bi-directional elastic telescopic rod 703 are stretched; when the end face of the electric slider 704 is in contact with the surface of the translation plate 702, the electric slider 704 no longer pushes the translation plate 702 to move, and the positioning plate 701 also stops moving. At this time, the end face of the positioning plate 701 located inside the first housing 1 is flush with the inner wall of the first housing 1; applying glue to the glue filling area in this state, the surface of the obtained glue layer can be flush with the surface of the rubber segment; it should be noted that the port of the first housing 1 is slightly narrowed, and the edge of the first housing 1 can clamp the rubber segment to ensure that the rubber segment will not shift along the length directions of the first housing 1 and the second housing 2 during the glue application process.

[0040] As Figure 4 , Figure 5 and Figure 6 As shown, the glue supply mechanism 6 includes a glue storage box 601 fixedly installed on the upper surface of the second housing 2. A glue spraying head 602 communicating with the inside of the glue storage box 601 and extending into the glue inlet 201 is installed on the bottom surface of the glue storage box 601; the glue supply mechanism 6 further includes a lifting rod 603. The lifting rod 603 vertically penetrates the second housing 2 in a sliding fit manner. A glue leveling plate 604 that cooperates with the inner wall of the second housing 2 is fixedly installed at the bottom end of the lifting rod 603. The glue leveling plate 604 has the same width as the positioning plate 701 and the end faces thereof facing the port of the second housing 2 are flush. The surface of the glue leveling plate 604 is flush with the inner wall of the second housing 2; a lifting platform 605 is fixedly installed at the top end of the lifting rod 603. A telescopic spring 606 sleeved on the lifting rod 603 is fixedly connected between the lifting platform 605 and the upper surface of the second housing 2; a roller 607 is rotatably installed on the lifting platform 605. A motor seat is fixedly installed on the upper surface of the second housing 2, and a motor 608 is fixedly installed on the motor seat. A special-shaped cam 609 corresponding to the position of the roller 607 is fixedly installed on the output shaft of the motor 608; the special-shaped cam 609 includes a plurality of convex blocks uniformly arranged along its circumference at its edge. The distance from the top of each convex block to the center of the special-shaped cam 609 is different, and within one circle, the distance from the top of the convex block to the center of the special-shaped cam 609 gradually decreases along the circumference.

[0041] After the two positioning plates 701 exit the glue filling area, the glue in the glue storage box 601 is sprayed into the glue filling area through the glue inlet 201 by the glue spray head 602, and the adhesive is gradually accumulated from bottom to top in the glue filling area; in this process, the motor 608 drives the special-shaped cam 609 to rotate one circle, and each convex block on the special-shaped cam 609 presses down the roller 607 in turn. After the roller 607 is pressed, it first drives the lifting platform 605, the lifting rod 603 and the glue leveling plate 604 to descend, and the telescopic spring 606 is compressed, and then the telescopic spring 606 is reset and drives the lifting platform 605, the lifting rod 603 and the glue leveling plate 604 to descend. Plate 604 rises and resets; during the descent process, the glue-leveling plate 604 squeezes the adhesive in the glue-filling area, helping the adhesive to be fully filled in all parts of the glue-filling area; it should be noted that, since the distance between the top of the protrusion and the center of the special-shaped cam 609 gradually decreases along the circumferential direction within a circle, the distance that the lifting platform 605, the lifting rod 603 and the glue-leveling plate 604 descend each time will also change. In the initial stage of glue filling, the amount of glue is small, and the distance that the glue-leveling plate 604 descends is large. As more and more glue is filled, the distance that the glue-leveling plate 604 descends decreases to avoid direct contact between the adhesive and the inner wall of the second frame 2.

[0042] It should be noted that the adhesive used in this embodiment is instant glue, which only needs to be kept static for a short time after gluing is completed to achieve solidification; and the first frame 1, the second frame 2, the positioning plate 701 and the glue plate 604 are all made of metal materials with smooth surfaces. When the thickness of the glue layer is very small, it will not produce a large bonding force with the above-mentioned parts. Even if the glue layer is solidified, the glue layer can be separated from the above-mentioned parts without permanent deformation itself.

[0043] like Figure 3 and Figure 8 As shown, a horizontal groove 202 is provided on the side wall of the glue inlet 201, and a glue cutting mechanism 8 is installed on the second frame 2, which includes a knife seat 801 horizontally slidably installed in the horizontal groove 202, and a cutting knife 802 is fixedly installed on the end face of the knife seat 801 facing the horizontal groove 202; the surfaces of the knife seat 801 and the cutting knife 802 are both flush with the inner wall of the second frame 2; an L-shaped translation frame 803 is horizontally slidably installed on the second frame 2, and the horizontal section end of the translation frame 803 is fixedly connected to the knife seat 801, and a horizontal elastic telescopic plate 804 is fixedly connected between the vertical section of the translation frame 803 and the second frame 2; a pressure ring 805 is vertically slidably matched in the glue inlet 201, and a pressure rod 806 is vertically fixedly installed on the upper surface of the pressure ring 805, a pressing sheet 807 is fixedly installed on the top of the pressing rod 806, and an elastic sheet 808 is fixedly connected between the pressing sheet 807 and the second frame 2.

[0044] After the glue supply mechanism 6 applies glue to the glue filling area, part of the adhesive will also be filled in the glue inlet 201 and the horizontal groove 202. After the adhesive cures, first keep the second frame 2 stationary. Manually push the translation frame 803 to drive the tool holder 801 and the cutting knife 802 to move horizontally. The cutting knife 802 cuts off the extra part of the glue block. The cut glue block remains in the glue inlet 201 and the horizontal groove 202. The surface of the glue layer below the cutting knife 802 is flush with the inner wall of the second frame 2. Finally, drive the second frame 2 to rise through the air cylinder 5. As described above, the first frame 1 has a certain clamping force on the glue section, and this clamping force causes the glue section to remain in the first frame 1, thereby promoting the separation of the cured glue layer from the second frame 2. During the rising process of the second frame 2, manually press down the pressing piece 807. The pressing piece 807 drives the pressing ring 805 to descend through the pressing rod 806, and the elastic piece 808 is compressed. The pressing ring 805 pushes the glue block remaining in the glue inlet 201 and the horizontal groove 202 downward out of the glue inlet 201, and the falling glue block can be caught manually. It should be noted that since the amount of glue supplied by the glue supply mechanism 6 each time is greater than the volume of the glue filling area, part of the adhesive will overflow into the glue inlet 201 and the horizontal groove 202 during each glue application process. The cutting mechanism 8 then cuts off the excess cured glue block. The purpose of this design is to ensure that the surface of the glue layer is flush with the glue section. If the amount of glue supplied is exactly the same as the volume of the glue filling area, the position of the glue layer corresponding to the glue inlet 201 will be uneven, and it is extremely difficult to ensure flatness, which will undoubtedly affect the sealing performance of the rubber ring.

[0045] The working steps of the rubber ring forming device in this embodiment are as follows: First, manually insert both ends of the glue section into the first frame 1 from both ends of the first frame 1. The positioning mechanism 7 positions both ends of the glue section so that the gap between the two end faces of the glue section corresponds to the position of the glue inlet 201. The gap between the two end faces of the glue section is the glue filling area. Then drive the second frame 2 to descend through the air cylinder 5 until the lower surface of the second frame 2 fits the surface of the glue section. Next, apply glue to the glue filling area through the glue supply mechanism 6, and the amount of glue applied each time is slightly larger than the volume of the glue filling area. After the glue layer cures, the cutting mechanism 8 cuts off the excess glue block. Finally, drive the second frame 2 to rise and reset through the air cylinder 5, and manually remove the formed rubber ring from the first frame 1.

[0046] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
