Ante handmade oil solid o-ring trimming operating proficiency dependence is also very prominent. Mechanical trimming oil o-ring. In order to improve efficiency and quality, there has been a mechanical trimming. Common is dedicated with a rotating blade electric trimmer. The height of the blade used to match demand and product size. If the inner and outer edges of the product have overflow edge. Can be designed as a double-edged, more cutting edge. In order to achieve a complete. Mechanical trimming precision than manual trimming, efficiency has improved several times, especially in a multi-cavity mold for the product concerned, in accordance with the arrangement and distribution of products, designed to match the tool. Until after the product out of the mold. Can put a full-page, once completed punching. Under heating with, one can repair dozens. The key is punching the temperature must be controlled, prevent the excessive adhesion. Frozen trimming oil o-ring. The vulcanization good product together with scrap, were in addition to the side in freezing conditions. The technology was developed by Japan's Showa 昭凌 carbonated and domestic joint invention improves the precision for decades, with the freezing medium of choice, updating and improving the mechanical action, frozen trimming also experienced several generations of improvements, maturity and perfection work efficiency and process quality has significantly improved. Install the O-ring (O-type rubber seals) requirements before installing the oil o-ring (O-type rubber seals), check the following: 1. The introduction of angle is according to drawings whether chamfer or round sharp edges; 2. Whether the inside diameter surface deburring pollution; 3. Is seals and parts have been smearing grease or lubricant fluid (to ensure media compatibility elastomer recommended to lubricate the seal with liquid); 4. shall not be used greases containing solid additives, such as molybdenum disulfide, zinc sulfide. Manually install the O-ring (O-type rubber seals): 1. Use no sharp edges of the tool; 2. Ensure that the O-ring (O-type rubber seals) do not distort, not excessive stretch O-ring (O-type rubber seal Circle); 3. Try using an auxiliary tool to install oil o-ring (O-type rubber seals), and to ensure correct positioning; 4. For sealing strip bonded to the O-ring (O-type rubber seals), shall not junction stretch. Mounting screws, splines, etc. 1. When the O-ring (O-type rubber seals) stretch, to when the screws, splines, keyways, etc. through, you must use the installation mandrel. The mandrel may be a relatively soft, smooth metal or plastic, without burrs or sharp edges. 2. When installing oil o-ring compression screws, tighten the screws should be symmetrical, not in the direction of tightening sequence.
