简析beplay全站app安卓加工精度把握之因素!

来源:http://www.jnhjgs.cn     发布时间:2021-06-21 11:22:24    点击:

要把握精 密beplay全站app安卓加工beplay全站app安卓的精度,工作程序如下:擦拭beplay全站app安卓并喷脱模剂―放人半成品(油封骨架及胶圈)―翻转合模―齿条传动将beplay全站app安卓送人硫化室―抽真空硫化―齿条传动将beplay全站app安卓送出至拖架上―启模―翻转―顶出产品。
To grasp the precision of precision mold processing, the working procedure is as follows: wipe the mold and spray release agent - put the semi-finished product (oil seal framework and rubber ring) - turn over and close the mold - rack drive to send the mold to the curing chamber - vacuum curing - rack drive to send the mold to the carriage - open the mold - turn over - eject the product.
据了解,两开橡胶油封beplay全站app安卓制造。两开油封beplay全站app安卓制造采用单体构件加工后,再组装相配,加工工艺优良,beplay全站app安卓检测方便。单腔beplay全站app安卓材质选用CrlZ,联板选用45钢。beplay全站app安卓加工过程中,除了严格按照beplay全站app安卓图纸加工,保证型腔尺寸外,以下几点是保证beplay全站app安卓加工精度的关键:
It is understood that the two open rubber oil seal mold manufacturing. The mould for two oil seals is made of single components and then assembled to match. The processing technology is excellent and the mould inspection is convenient. The material of single cavity die is crlz, and the connecting plate is 45 steel. In the process of mold processing, in addition to strictly following the mold drawing to ensure the cavity size, the following points are the key to ensure the mold processing accuracy:
(l)流胶槽的加工:过去油封beplay全站app安卓流胶槽的精 密beplay全站app安卓加工没有得到充分的重视,流胶槽往往加工得距离型腔太远或尺寸不易控制,使制品修剪困难,产品不美观。两开油封beplay全站app安卓针对这些问题已经作了改进,三角形的流胶槽内端尺寸与产品外径处尺寸一致(零对零),利用对开的上、下模在此处形成尖锐的刃口状,油封模压成型时,多余飞边即被剪切下来,既简化了修边工序,又提高了产品的外观。由于流胶槽与型腔外径分别处在不同的模块上,尺寸不发生干涉,其精度也容易保证。
(l) Flow groove processing: in the past, the precision mold processing of oil seal mold flow groove did not get enough attention, flow groove is often processed too far from the cavity or the size is not easy to control, so that the product is difficult to trim and the product is not beautiful. The two split oil seal mould has been improved to solve these problems. The inner end size of the triangle flow groove is consistent with the outer diameter of the product (zero to zero). The split upper and lower mould forms a sharp edge here. When the oil seal is molded, the excess flash is cut off, which not only simplifies the trimming process, but also improves the appearance of the product. Because the flow groove and the outer diameter of the cavity are on different modules, the size does not interfere, and the accuracy is easy to guarantee.

(2)上模与上模芯1的配合加工:上模与上模芯1的配合为锥度配合,以往采用研配的方法,要求接触率达到80%以上。这种传统的加工方式不仅难度大,而且耗费很多工时,仍然难以达到没有飞边的理想效果。新结构beplay全站app安卓的加工采用锥孔的倾斜角度比锥轴的倾斜角度略小的办法,使上模与上模芯在分型面b处总是紧紧地贴合在一起,处于无间隙配合的状态,所以产品在此处不存在飞边。且beplay全站app安卓制造工艺性改善。
(2) Matching processing of upper die and upper die core 1: the matching of upper die and upper die core 1 is taper matching. In the past, the matching method was used, and the contact rate is required to be more than 80%. This traditional processing method is not only difficult, but also costs a lot of man hours, and it is still difficult to achieve the ideal effect without flash. The processing of the new structure die adopts the method that the inclination angle of the taper hole is slightly smaller than that of the taper shaft, so that the upper die and the upper die core are always tightly bonded together at the parting surface B, in the state of no gap fit, so there is no flash in the product here. And the mold manufacturing process is improved.
(3)上模芯1与上模芯2的压合:上模芯1与上模芯2的压合是保证油封副唇尺寸及精度的关键。三开油封beplay全站app安卓副唇处的飞边,对副唇处的外观影响很大。新结构beplay全站app安卓将上模芯1与上模芯2采用过盈配合,单体加工后,用热胀法压合成一体,再由上端的紧固螺钉将上模芯2紧紧拉住,有效地阻止副唇处两模芯的松动。
(3) Pressing of the upper die core 1 and the upper die core 2: the pressing of the upper die core 1 and the upper die core 2 is the key to ensure the size and accuracy of the oil seal lip. The flash at the secondary lip of the three opening oil seal mold has a great influence on the appearance of the secondary lip. In the new structure mold, the upper mold core 1 and the upper mold core 2 adopt interference fit. After the monomer is processed, it is pressed into one by thermal expansion method, and then the upper mold core 2 is tightly pulled by the upper fastening screw to effectively prevent the loosening of the two mold cores at the auxiliary lip.
(4)各腔beplay全站app安卓之间的连接:各单腔beplay全站app安卓与联板的连接必须有一定的浮动量,以保证精 密beplay全站app安卓加工开合灵活,找正准确。一般单模与联板间的间隙控制在0。50一1。0rnm。间隙过大易造成beplay全站app安卓使用时偏旋转轴油封新结构beplay全站app安卓的研制斜太大,beplay全站app安卓磨损加剧,影响beplay全站app安卓的使用寿命;间隙过小则使beplay全站app安卓操作时各模腔间发生干涉,卡得过。
(4) Connection between the cavity molds: the connection between the single cavity mold and the connecting plate must have a certain floating amount to ensure the flexible opening and closing and accurate alignment of the precision mold processing. Generally, the gap between single-mode and coupling plate is controlled at 0. 50-1. 0rnm。 If the clearance is too large, it is easy to cause the deviation of the new structure of the rotary shaft oil seal when the die is used. The development of the new structure of the die is too large, and the wear of the die is intensified, which affects the service life of the die; If the gap is too small, there will be interference between the die cavities during the operation of the die, and the die will be stuck.
旋转轴油封两开beplay全站app安卓的研制改变了传统三开模结构型式,使油封制品外观及性能得以保证,大大提高了工作效率。
The development of two opening die for rotary shaft oil seal changes the traditional three opening die structure, ensures the appearance and performance of oil seal products, and greatly improves the work efficiency.
