Double-head nut projection welding machine is a double-head nut projection welding machine tailored by Anjia for customers according to customer needs, according to product materials and welding processes. It has the characteristics of no return to teeth after welding, high welding efficiency, strong applicability, automatic alarm, fault diagnosis, intelligent control system, and guaranteed welding quality. The scenario when a customer finds us is:
I. Customer background and pain points
Changshu FQ Co., Ltd. is an old-fashioned auto parts company. The main products are auto parts, etc., which require welding nuts and gaskets for resistance welding machines. As a result of receiving a batch of symmetrical nut and gasket welding products, the quantity is very large, and the pressure for product delivery is very high. In addition, if a conventional resistance welding machine is used, the number is large, the investment cost is high, and it is difficult for workers to arrive in a short time. Customers have always wanted to find a good welding automation solution to solve the current problems. The problems encountered are:
1. The problem of insufficient capacity cannot be solved in a short time;
2. The quality of welded products is high, the nuts are easy to return to the teeth, and the rework is time-consuming and laborious;
3. Welding efficiency is low, welding symmetry cannot be guaranteed, and consistency is poor;
4. Large manual investment and difficult management;
Second, customers have high requirements for equipment
According to product characteristics and past experience, FQ put forward the following requirements for new custom equipment after discussion with our sales engineers:
1.One device, welding two symmetrical nuts or washers at a time;
2. The welding efficiency should be more than doubled compared to the previous standard machine, and there should be no back teeth after welding the nut;
3. The equipment must have a gas and water alarm, and the fault can be self-diagnosed;
4, equipment discharge can work with other resistance welding at the same time can be peak discharge, control equipment energy;
According to the requirements of customers, ordinary standard spot welding machines cannot be realized at all, what should I do?
3. Develop custom double-head nut welders according to customer needs
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, used our existing spot welding machine to proof test, and performed small batch verification to basically determine the welding parameters;
2. Equipment selection : The R & D engineer and welding technician communicated together and calculated the selection power according to the customer's investment budget requirements. Finally, it was confirmed as a 100KVA × 2 pneumatic AC spot welding machine;
3. Equipment advantages :
1) Improve welding efficiency : adopt the structure of double-head welding machine, double power supply, double welding cylinder, one welding switch workpiece clamping at a time, fully automatic welding, welding efficiency increased by 50%;
2) Strong equipment compatibility : the two welding heads of the special welding conductive mechanism and the welding cylinder fixing mechanism can be moved freely within a certain range, which solves the problem of compatibility of welding products of non-standard welding machines, and can weld multiple specifications of products in one machine;
3) Strong applicability : The dual power supply structure is adopted, and the dual welding heads can move at the same time, and any welding head can work independently, which has strong applicability;
4) Solve the problems of welding quality and power grid impact : The equipment adopts our own self-developed control system, with automatic alarm for air pressure overrun, self-diagnosis of faults, and factory aging test to ensure the stability of the equipment when it leaves the factory. In order to improve the welding quality and adjust the control through our control system, it can solve the peak discharge when the equipment discharge can work with other resistance welding at the same time to avoid the impact of the power grid;
5) Open equipment communication : We use the same communication protocol as the conventional communication protocol to design and manufacture equipment control programs. At the same time, we open the control port so that the external control system can communicate with our equipment. open;
Anjia fully discussed the above technical solutions, details, and FQ. After the two sides reached an agreement, they signed a "Technical Agreement" as the standard for equipment R & D, design, manufacturing, and acceptance, because our meticulousness touched the customer, and on February 9, 2016 Japan and FQ Company reached an order agreement.
Fourth, fast design, on-time delivery, professional after-sales, and get praise from 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.
Ten working days in the past, the FQ custom double-head nut welding machine was finally completed after aging tests. Our professional after-sales engineer passed the 1-day installation and commissioning and technical, operation, and maintenance training at the customer site. The equipment has been put into production and All met the customer's acceptance criteria.
FQ Company is very satisfied with the actual production and welding results of the double-head nut welding machine, helping them improve production efficiency, improve welding quality, save labor, and solve the problem of power grid impact, and they have been highly recognized and praised!
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, production line or assembly line? ”。 Please do not hesitate to mention that Anjia can " research and develop " for you.
