Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] In the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0026] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0027] like Figure 1-8As shown, this embodiment provides a rubber strip seamless ring-forming tooling, including an upper seat 1 and a base 2 connected thereto, wherein the upper seat 1 is provided with a accommodating cavity 12, wherein the accommodating cavity 12 is provided with a movable middle seat 4 and a pressure-bearing member 3 connected to the middle seat 4 and capable of extending out of the upper seat 1; a cutter 5 is connected to the side of the middle seat 4 away from the pressure-bearing member 3, and the base 2 is provided with a cutting groove 8 matching the cutter 5 facing the cutter 5.
[0028] In some embodiments, the middle seat 4 is provided with a positioning hole 10, a positioning pin 6 is passed through the positioning hole 10, one end of the positioning pin 6 is fixedly connected to the base 2, and a spring 7 is provided on the outer sleeve of the positioning pin 6, one end of the spring 7 abuts against the middle seat 4, and the other end abuts against the base 2.
[0029] In this embodiment, the positioning pin 6 and the spring 7 play a supporting role and a spring-up and reset role for the middle seat 4 on the base 2. The middle seat 4 can move relative to the positioning pin 6 during the movement in the accommodating cavity 12. When the middle seat 4 is pressed to move downward and squeeze the spring 7, the pressure is removed and the middle seat 4 is lifted up and reset under the elastic force of the spring 7.
[0030] In some embodiments, the cutting knife 5 includes a second annular knife 52 and a first annular knife 51 sleeved outside the second annular knife 52, and the cutting knife groove 8 includes a second annular groove 82 and a first annular groove 81 sleeved outside the second annular groove 82; the first annular knife 51 is adapted to the first annular groove 81, and the second annular knife 52 is adapted to the second annular groove 82.
[0031] In this embodiment, the two annular knives and the two annular grooves are both annular, the first annular knife 51 can be inserted into the first annular groove 81, and the second annular knife 52 can be inserted into the second annular groove 82, so that the cutter 5 can cut out an annular O-ring rubber blank during the movement of the cutter 5 to the cutter groove 8. Specifically, when the cutter 5 cuts to the bottom, the cutter groove 8 can protect the cutter 5 from directly contacting the base 2, which on the one hand prolongs the service life of the cutter 5, and on the other hand prevents the cutter 5 from contacting the base 2 to produce debris, which affects the cleanliness of the seamless rubber ring, thereby preventing the product from being scrapped due to the mixing of particulate impurities or unqualified conductivity, thereby ensuring product quality and a high yield rate.
[0032] In some embodiments, an ejector rod 11 is inserted into the middle seat 4 , and the ejector rod 11 is fixedly connected to the upper seat 1 .
[0033] In some embodiments, the ejector rod 11 is located between the first annular knife 51 and the second annular knife 52 .
[0034] In this embodiment, the upper seat 1 and the ejector rod 11 are an integral structure, and the middle seat 4 can move up and down relative to the ejector rod 11. After the cutter 5 cuts out the annular O-ring rubber blank, the middle seat 4 and the cutter 5 are lifted up by the spring 7, while the upper seat 1 and the ejector rod 11 are fixed, so that the ejector rod 11 ejects the preformed seamless rubber ring from the cutter 5, so that the seamless rubber ring falls between the middle seat 4 and the base 2 for easy removal.
[0035] In some embodiments, the pressure-bearing member 3 is cross-shaped and is externally connected to the punching part of the punching machine. The pressure-bearing member 3 drives the middle seat 4 to move downward when it is pressed. When the pressure-bearing member 3 is not pressed, the middle seat 4 and the pressure-bearing member 3 are lifted up by the elastic force of the spring 7 and return to their original positions. When the pressure-bearing member 3 is pressed and completely enters the upper seat 1, the punching machine cannot continue to press the pressure-bearing member 3 downward, but directly applies pressure to the upper seat 1, so that the cutter 5 can only move in the set position, avoiding hard contact between the cutter 5 and the base 2, and protecting the cutter 5.
[0036] In some embodiments, a material taking cavity 9 is provided on one side of the upper seat 1 facing the base 2, and the material taking cavity 9 is located on the base 2 and communicated with the accommodating cavity 12. Materials are taken and placed on the cutting groove 8 of the base 2 through the material taking cavity 9.
[0037] The working process of the rubber strip seamless loop forming tool provided in this embodiment is as follows:
[0038] S1, placing the rubber strip seamless ring forming tool on the base of the punching machine;
[0039] S2, inserting the strip film between the base 2 and the cutter 5;
[0040] S3, the punching machine punches down to complete the cutting;
[0041] S4, the punching machine moves upward, the cutter 5 and the middle seat 4 are lifted up by the elastic force of the spring 7, and at the same time, the ejector rod 11 fixedly connected to the upper seat 1 ejects the cut rubber ring;
[0042] S5, remove the cut seamless rubber ring and the remaining materials, use the rubber strip to push out the outer edge of the cut material, and continue the operation of S2-S5;
[0043] S6. After completing the operation, clean the tooling and store it in a dust-free box.
[0044] The rubber strip seamless ring forming tool provided by the utility model is adapted to the first annular knife 51 and the first annular groove 81, and the second annular knife 52 and the second annular groove 82, so that the cutter 5 can cut out an annular O-ring rubber blank during the movement of the cutter groove 8. When the cutter 5 cuts to the bottom, the cutter groove 8 can protect the cutter 5 from directly contacting the base 2, which on the one hand prolongs the service life of the cutter 5, and on the other hand avoids the cutter 5 and the base 2 from contacting and scratching out debris, affecting the cleanliness of the seamless rubber ring, thereby avoiding the product from being scrapped due to the mixing of granular impurities or unqualified conductivity, ensuring the product quality and high yield rate. In addition, after the cutter 5 cuts out the annular O-ring rubber blank, the middle seat 4 and the cutter 5 are lifted up by the spring 7, while the upper seat 1 and the ejector rod 11 are fixed, so that the ejector rod 11 ejects the preformed seamless rubber ring from the cutter 5, so that the seamless rubber ring falls between the middle seat 4 and the base 2 for easy removal. The rubber blank produced by the seamless ring-forming tooling of the rubber strip omits the process of baking, positioning and shaping, and eliminates the problem of the perfluoroether rubber strip shrinking due to long operation time during the placement process, which causes the perfluoroether rubber surface to burn. It has a high yield rate and high production efficiency.
