具体实施方式detailed description
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
请参阅图2，本发明公开了一种橡胶撑开爪10，其包括爪柄11、爪体12。爪柄11与爪体12为一体成型结构，避免脱焊爪柄11脱焊于爪体12。Referring to FIG. 2 , the present invention discloses a rubber spreading claw 10 , which includes a claw handle 11 and a claw body 12 . The claw handle 11 and the claw body 12 are integrally formed to prevent desoldering of the claw handle 11 from the claw body 12 .
爪体12包括爪尖13、爪身14、爪杆15，爪身14衔接爪尖13与爪杆15，且爪尖13、爪杆15分别位于平行的两个不同层面上使爪身14相对爪尖13、爪杆15倾斜。爪尖13、爪身14、爪杆15一体成型使爪体12本身就是一体成型的结构。Claw body 12 comprises claw tip 13, claw body 14, claw bar 15, and claw body 14 connects claw tip 13 and claw bar 15, and claw tip 13, claw bar 15 are respectively positioned on two different parallel levels so that claw body 14 is relative to claw tip 13, The claw lever 15 is inclined. The claw tip 13, the claw body 14, and the claw rod 15 are integrally formed so that the claw body 12 itself is an integrally formed structure.
爪杆15收容在爪柄11内而与爪柄11固定，爪柄11与爪杆15为一体成型结构，在本实施方式中，橡胶撑开爪10采用冷作模具钢材一体成型，以使爪柄11与爪杆15为一体成型结构而使爪柄11与爪体12实现一体成型。冷作模具钢材具有高强度、高韧性的特点，能满足生产所需要的防止变形、断裂的要求。The claw bar 15 is accommodated in the claw handle 11 and is fixed with the claw handle 11. The claw handle 11 and the claw bar 15 are integrally formed. The handle 11 and the claw rod 15 are integrally formed so that the claw handle 11 and the claw body 12 are integrally formed. Cold work die steel has the characteristics of high strength and high toughness, which can meet the requirements of preventing deformation and fracture required for production.
爪身14与爪柄11的交界处呈圆弧过渡，即爪身14与爪柄11的弯曲连接处采用大“R”过渡，因而能减小应力集中，来避免爪体12根部断裂，即避免爪身14连接爪柄11的一端断裂。The junction of the claw body 14 and the claw handle 11 is a circular arc transition, that is, the curved connection between the claw body 14 and the claw handle 11 adopts a large "R" transition, thereby reducing stress concentration and preventing the root of the claw body 12 from breaking, that is Avoid breaking one end of the claw body 14 connected to the claw handle 11.
爪尖13的长度尽量大于爪身14的长度，以便能伸入橡胶管或橡胶套内。The length of claw point 13 is greater than the length of claw body 14 as far as possible, so that can stretch in the rubber tube or rubber cover.
本发明经120天的使用验证：所有橡胶撑开爪在多次试验过程中均没有出现问题，可以达到20万次无断裂、无变形。The present invention has been verified after 120 days of use: all rubber spreading claws have no problems in the course of multiple tests, and can reach 200,000 times without breaking or deforming.
另外，橡胶撑开爪的加工工艺尽量进行调整：棒料——锻造——切削加工——加热弯曲——钳工修形——表面抛光——侧面铣定位面。切削加工时，爪身14与爪柄11的弯曲连接处采用大“R”过渡，并尖角滚压处理，加热弯曲时，橡胶撑开爪的热处理尽可能采用整体热处理，并增加表面处理消除微小裂纹。棒料采用具有高强度、高韧性的冷作磨具刚；锻造是热处理的关键点，用以消除锻造裂隙即微小裂纹。橡胶撑开爪的加工工艺客服了原有的易断裂、易弯曲变形、造价高和使用寿命短的问题。In addition, the processing technology of the rubber spreader claws should be adjusted as much as possible: bar material - forging - cutting processing - heating bending - fitter modification - surface polishing - side milling positioning surface. During the cutting process, the curved connection between the claw body 14 and the claw handle 11 adopts a large "R" transition, and the sharp corners are rolled. tiny cracks. The bar is made of high-strength, high-toughness cold-working abrasive steel; forging is the key point of heat treatment to eliminate forging cracks, that is, tiny cracks. The processing technology of the rubber spreading claw overcomes the original problems of easy breakage, easy bending deformation, high cost and short service life.
根据三点确定一个平面的原理，至少三个橡胶撑开爪10可构成一个橡胶撑开装置，橡胶撑开装置用于撑开橡胶品(如橡胶管、橡胶套)。请参阅图3，该橡胶撑开装置处于闭合状态时，橡胶品16套设在该橡胶撑开装置的三个橡胶撑开爪10上，三个橡胶撑开爪10的爪尖13相互集中且相应的爪尖13端面构成呈球冠形；请参阅图4，当该橡胶撑开装置处于撑开状态时，三个橡胶撑开爪10的爪尖13相互分离扩大橡胶品16的橡胶管或橡胶套的直径，将橡胶品16撑开。该橡胶撑开装置在应用时，三个橡胶撑开爪10的张开或闭合的角度、力度、速度要尽可能一致，实现三爪默契配合。According to the principle of determining a plane at three points, at least three rubber spreading claws 10 can form a rubber spreading device, which is used to stretch rubber products (such as rubber tubes, rubber sleeves). Please refer to Fig. 3, when the rubber spreading device is in the closed state, the rubber products 16 are sleeved on the three rubber spreading claws 10 of the rubber spreading device, and the claw tips 13 of the three rubber spreading claws 10 are mutually concentrated and correspondingly The end faces of claw points 13 constitute a spherical crown; please refer to Fig. 4, when the rubber stretching device is in the stretched state, the claw points 13 of the three rubber stretching claws 10 are separated from each other to expand the rubber tube or rubber sleeve of the rubber product 16 Diameter, the rubber product 16 is stretched out. When the rubber spreading device is in use, the angles, strengths and speeds of the opening or closing of the three rubber spreading claws 10 should be as consistent as possible, so as to realize the tacit cooperation of the three claws.
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention.
