Hwashi Automatic CNC Sink DC Seam Rolling Welding Machine for Stainless Steel Kitchen Sink Bowl Making Machine

Main Features

When the welding wheel rolls continuously or intermittently under continuous or intermittent current pulse, the welding seam which is composed of a series of welding spots will be formed. However, the distance between welding spots will be reduced which will make the nugget overlap with each other. When the overlap degree exceed 1/3 of the diameter of the nugget, then a certain degree of air tightness welding will occur. For the sake of ensuring the stability of welding quality, medium frequency inverter power source will be adopted. Adopt the professional automatic control system, as long as input the data like coordinate data of the position of welding products, welding current, etc., then after turning on the machine, the welding track will automatically finish welding product within the preset procedure. The workers only need to put the work piece onto certain place and then take it away when finishing welding.

Use the servo motor to drive axle X (locating mould) and axle Y (welding electrode) to operate under the preset procedure of PLC data. It could store 15 sets of welding models at most (be able to store 15 sets of welding position and welding current of product). According to the stored position of welding spot, the welding product will be located inside the mould and moves horizontally along the X direction and the moving area should be no more than 1200mm. The welding electrode will be designed to move vertically along the Y direction and the moving area should be no more than 600mm. The welding electrode moves from top to bottom within 300mm along the axle Z direction and be able to conduct 360° of rotation under the control of servo motor so it is suitable for welding different angles of products.

Japan Mitsubishi CNC Control System Adopts three sets of Japan Mitsubishi servo motor to control axis X (movement of sink mould), axis Y (vertical movement of welding wheel), and axis A (360° rotation of welding wheel).

Auto Moving Welding Table Specially designed electrode large table, more stable conductivity, to ensure the effectiveness of welding.

Big Copper Flat Table Electrode and Fixture We will design the fixture according to the design of your sink bowl. Different sizes may require different fixtures. Be able to do welding of single bowl, double-bowl, or three-bowl product

Welding electrode Synchronized operation of welding electrodes and Moving Welding Table, Automatic welding of sink, Uniform and beautiful welding seam.

 

 

CNC Sink Edges Grinding and Polishing Machine

This is the special designed machine for grinding and polishing the seam after welding. Normally customer will choose to buy these two machines together so as to complete the production of kitchen sink. This CNC sink grinding special machine utilizes abrasive belt polishing principle. The abrasive belt is driven by electric motor to conduct polishing on the edge of the welded sink. There are two processes for polishing. Firstly, use the coarse abrasive belt to grind the redundant cutting edge and the projection welding spots. Then use the fine abrasive belt to conduct polishing treatment. After these two processes can meet the requirement of sink grinding and polishing treatment.

Special Design Grinding Belt	Auto Moving Table and Fixture Structure
Brown belt (fine abrasive belt) DEERFOS RA631 150# Blue belt (coarse abrasive belt) 577F P80Y The movement and control system will be the same as the sink seam welding machine	For sink bowl within 1500mm, we can choose to use fixed table with adjustable fixture. For sink bowl over the limit, we can design the automatic moving feeder to achieve full automatic grinding and polishing.

This CNC sink grinding special machine utilizes abrasive belt polishing principle. The abrasive belt is driven by electric motor to conduct polishing on the edge of the welded sink. There are two processes for polishing. Firstly, use the coarse abrasive belt to grind the redundant cutting edge and the projection welding spots. Then use the fine abrasive belt to conduct polishing treatment. After these two processes can meet the requirement of sink grinding and polishing treatment. It is designed to use Mitsubishi professional automatic control system. You only need to input the coordinate data of the product and start the machine, the abrasive belt of the machine will conduct grinding and polishing automatically within the track of preset program. The worker only needs to put and take out the sink.

The product will be fixed on the locating mould. The servo motor will drive the X and Y axle to run within the preset data of program. The machine could store 15 types of grinding models. The grinding wheel will move along with X direction and the max moving range is 1220mm while the max moving range of Y direction is 620mm. The Z axle can conduct moving up and down within the range of max 250mm while the A axle can conduct 360ºrotating under the control of servo motor. This machine is suitable for different directions of product.
