Suzhou YJ Electronics Co., Ltd. is committed to supporting sheet metal stamping parts and injection molding parts for household appliances, meters, automobiles and other industries, mainly supporting Samsung air conditioners, Nissan compressors, General Motors, etc., mainly researching and developing and producing air conditioner compressor housings and refrigerator compressors Products such as housings, instrument housings, and automotive stamping parts are now undertaking Samsung's air-conditioning compressor components. We need to weld the compressor housing and the suction copper tube. The problems encountered are:
I. Customer background and pain points
• Does not meet customer requirements, customers do not accept the original brazing process;
• Environmental protection is not up to standard, after the welding is completed, the brazing seam needs to be cleaned, and the drainage pressure is high;
• Welding efficiency is too low, brazing takes time and effort;
• Welding costs are high, and there is consumption of solder and acetylene gas;
• Deviation in verticality and position after welding;
The above five customers are very distressed and have not been able to find a solution.
Second, customers have high requirements for equipment
YJ found us online on February 5, 2015, discussed with our sales engineers and wanted to customize the special welding equipment with the following requirements:
1. Meet customer requirements and complete with resistance welding process;
2. Do not clean the weld after welding;
3. Improve welding efficiency;
4. No need to clean up solder and acetylene gas;
5. Ensure that there is a deviation between the verticality and the position after welding;
According to the customer's requirements, the original equipment and technology cannot be realized at all, what should I do?
Third, according to customer needs, research and development of custom compressor housings and suction copper tube special welding machine
According to the customer's requirements, the company's R & D department, welding process department, and sales department jointly held a new project research and development meeting to discuss the process, fixture, structure, feeding method, and configuration, list key risk points, and make one by one The solution, the basic direction and technical details are determined as follows:
1. Workpiece proofing test : Anjia Welding Technician made a simple fixture for proofing at the fastest speed, and used our existing intermediate frequency DC welding machine for proofing test. First, the copper pipe needs to be pierced by ribs, and then the steel shell Welding, withstand voltage test to meet customer requirements, do small batch verification, and basically determine welding parameters;
2. Equipment selection : The R & D engineer communicated with the welding technologist, determined the selected power through actual measurement, and finally confirmed it as ADB-640 IF inverter DC projection welding machine;
”，如ABB的大功率二级管，Semikron的IGBT逆变模块等； 3. Stability of equipment : Our company uses all “ imported configurations ” of core components, such as ABB's high-power diodes and Semikron's IGBT inverter modules;
4. Equipment advantages :
完全满足“三星”压缩机的工艺要求； 1) Breakthrough in technology and guaranteed quality : The ADB-640 IF inverter DC projection welding machine we selected, full-wave rectification, DC output, high peak value and fast climbing, is the most advanced power supply at present; by guiding customers to The ribs are raised out of the pier and then welded to the steel shell, which fully meets the technological requirements of the "Samsung" compressor;
2) Save labor cost and high efficiency : Through the projection welding verification of the intermediate frequency inverter DC welder, the ribs of the copper pipe pier can be welded to the shell, and the base metal of the weld itself is fused, so there is no need to clean the weld additionally;
3) High welding efficiency : The resistance ring projection welding is used to increase the beat of the original copper pipe to the shell to 4.5 seconds, which is 80% higher than the original brazing process;
4) Save production costs : Welding is accomplished by resistance heat, and the copper tube and the shell are connected in a plastic state through the large current through the contact area of the workpiece, without the need for external solder and heating;
5) The special electrode and fixture are used to fix the shell to the lower fixture, and the copper tube to the upper electrode. After adjusting the concentricity, the verticality after welding can be guaranteed, and the position of the product can be satisfied.
5. Delivery time: 40 working days.
Anjia discussed the above technical solutions and details with YJ. After the two parties finally reached an agreement, they signed a "Technical Agreement" as the standard for equipment R & D, design, manufacturing, and acceptance, because our thoughtfulness touched the customer. On May 25, an order agreement was reached with YJ.
Fourth, rapid design production capacity, professional after-sales service, highly recognized by customers
After confirming the equipment technical agreement and signing the contract, Anjia's project manager held the production project launch meeting as soon as possible, and confirmed the mechanical design, electrical design, machining, outsourced parts, assembly, joint adjustment time nodes and customers to come to the factory for pre-acceptance. , Rectification, general inspection and delivery time, and orderly issue work orders of each department through the ERP system, supervise and follow up the work process of each department.
After 40 working days in a flash, YJ customized ADB-640 compressor suction pipe ring convex welding machine was completed after aging test. Our professional after-sales engineer went through 3 days of installation and commissioning and technical, operation and maintenance training at the customer site. The equipment has been put into production normally and all reached the customer's acceptance standards.
YJ Company is very satisfied with the actual production and welding effect of the ADB-640 compressor suction pipe ring convex welding machine, helping them solve the process breakthrough, ensure the welding quality, improve the welding efficiency, reduce the cost, and give us high recognition. And praise!
Fifth, meet your customization requirements is the growth mission of Anjia!
The customer is our mentor. What material do you need to weld? What welding process do you need? What welding requirements? Need full-automatic, semi-automatic, or assembly line? ” Please do not hesitate to mention that Anjia can develop and customize for you
