What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃.   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

알루미늄 합금 다이캐스팅의 단점을 해결하는 것이 편리합니다!

알루미늄 합금 다이캐스팅은 현재 현재의 전자제품 , 자동차 , 생활필수품 등 많은 산업과 분야에서 널리 사용되고 있습니다 . 그러나 알루미늄 합금 다이캐스팅에서 자주 발생하는 몇 가지 결함 및 해결 방법은 다음과 같습니다 .   알루미늄 합금 다이캐스팅   1. 불순물   알루미늄 합금 다이 캐스팅의 불순물 문제는 주로 특정 온도에서 알루미늄 , 규소 및 다량의 철 , 망간 , 크롬 및 기타 화합물을 포함하는 결정립과 일부 산화물로 구성됩니다 .   해결책 : 알루미늄 잉곳의 조성을 엄격하게 제어하고 , 제련로의 난로를 정기적으로 청소하고 , 정기적으로 슬래그를 처리하면 문제를 해결할 수 있습니다 .   2. 구강 문제   다공성은 다이캐스팅 부품의 내부 또는 표면에 나타나는 다양한 크기의 구멍을 말하며 , 이는 다이캐스팅 부품의 경도 부족으로 이어져 표면의 외관에 영향을 줍니다 .   Solution: 적절한 정제제를 사용하여 모공을 처리하고 , 공정을 조정하고 , 저속을 적절하게 줄이고 , 이형제가 너무 많이 분사되어 모공 문제가 해결되지 않는지 확인하십시오 .   3. 균열 문제   균열은 알루미늄 합금 다이캐스팅의 매트릭스가 파괴되고 , 외력의 작용에 따라 확장되는 경향이 있는 선형 또는 기타 라인인 기다란 틈이 형성되는 것을 의미합니다 .   솔루션 : 합금 조성을 올바르게 제어하고 , 냉각수 회로를 늘리고 , 알루미늄 합금 다이캐스팅의 구조를 변경하고 , 사출 위치를 변경하거나 증가시키면 해결할 수 있습니다 .

Inspection strategy of tire full-speed anti-breakage testing machine

Standard model and parameters Model and name Maximum test value accuracy/% EHB-100A standard dynamometer 10000kg 0.3 SZG-141B digital speed 10000rmin-10.0222 self-inspection conditions Working temperature 1035, the environment is dry, clean, and vibration-free.

The difference between the load display value of the self-checking equipment load and the actual force applied to the drum is the load error. (1) The installation of the EHB-100A standard dynamometer The standard dynamometer is fixed on the bracket, the dynamometer probe should be located on the plane composed of the rim and the center axis of the drum, and the end with the probe rests on the drum Up, the other end is towards the rim, as shown.

(2) Load test Choose 5 force points for load test on each station. In accordance with our factory’s inspection requirements for finished tires, five force points of 1, 2, 3, 4 and 5t are selected at the 1 and 2 stations. The installation of the EHB-100A standard dynamometer indicates the rim; 2 standard dynamometer ; 3 brackets; 4 drums and 4 stations to choose five force points 0.5, 0.8, 1, 1.5 and 2t. The equipment applies a load from the rim to the standard dynamometer through hydraulic transmission. When the equipment displays the selected afterburner value Xi (i=15), the readings Li of the standard dynamometer are recorded respectively.

(3) Calculation of load error The relative load error i corresponding to each point is calculated according to formula (1): i (%) = Xi-LiLi100 (1) The difference between the speed error of the self-checking device speed display value and the actual linear speed of the drum Is the speed error.

(1) Speed ​​measurement The SZG-141B digital tachometer is portable, so there is no need to install it. When testing, stick the reflective film on the drum and hold the steady tachometer. When measuring the speed, use the tachometer to obtain the standard value of the drum speed Ni first after the drum rotates stably. According to the diameter of the drum, the standard linear velocity value vi of the outer edge of the drum can be calculated as 0.3216Ni. Measuring 1 and 2 stations At the speed, the measured speed vi given by the equipment starts from 50kmh-1, and the speed is increased by 20kmh-1 each time until the speed reaches 150kmh-1, and then the speed is increased to 160kmh-1, and the standard speed Ni of the drum is measured with the tachometer. When measuring the speed at stations 3 and 4, the measured speed vi given by the equipment starts from 80kmh-1, and increases the speed by 20kmh-1 each time until the speed reaches 220kmh-1. At the same time, record the standard rotation speed value corresponding to each speed. The same method can calculate the standard linear velocity at each speed.

(2) Calculation of speed error The relative speed error i corresponding to each point is calculated according to formula (2): i(%)=vi-vivi100=vi-0.3216Ni0.3216Ni100 (2) Processing of self-check results at each point in load detection The absolute value of the corresponding load relative error is less than the load accuracy requirement, then the load test is qualified; the absolute value of the speed relative error corresponding to each point in the speed test is less than the speed accuracy requirement, then the speed test is qualified. If one of the items checked above is unqualified, the equipment is deemed unqualified and must be re-adjusted and tested until all items are qualified.
