Problems solved by technology

[0002] When the flash welding machine is welding, the welding slag is easily adsorbed and bonded to the electrode base and the side of the electrode, causing the running knife to be blocked. In severe cases, the electrode will be knocked off during the falling process of the knife. The machine was put into use in 1996 and has been in operation for nearly 20 years. During this period, there has been no modification of the mechanical and electrical systems, and the equipment is seriously aging; the electrode plate of the welding machine is copper plate, which will increase the maintenance cost when it is abnormally damaged; the side of the electrode is adhered Welding slag is formed more firmly at high temperature, which often results in longer downtime during cleaning; replacing the electrode in advance shortens the service life of the electrode, which increases the operating cost; using the seam knife to repeatedly lift and rub off part of the welding slag, there is a risk of knocking the electrode off , Conventional welding machine electrode welding slag cleaning methods and disadvantages For the welding slag adhered to the side of the welding machine electrode base, the method of repeatedly lifting and lowering the slit knife is used to remove the adhered welding slag by friction, but this method is not cleaned thoroughly, and When the adhesion of welding slag is relatively strong, it is easy to knock off the electrode, resulting in unnecessary shutdown and electrode replacement

Embodiment 1

[0021] The specific embodiments of the invention will be further described below in conjunction with the accompanying drawings.

[0022] See figure 1 , is a schematic structural view of the slag removal device of the present invention. The flash welding machine electrode welding slag cleaning method and cleaning tool described in the present invention comprise the following steps:

[0023] Step 1: Replace the electrode;

[0024] Step 2: Apply 2# lithium-based grease on the sides of the upper and lower electrode bases with a width of 110mm, and the thickness of 2# lithium-based grease is 0.5mm;

[0025] Step 3: Turn on the machine and start working;

[0026] Step 4: Use the cleaning tool to clean up the welding slag when the machine is shut down to replace the work roll;

[0027] Step 5: Use a cleaning tool to clean the welding slag on the electrode. After cleaning the welding slag, apply 2# lithium-based grease on the electrode base and the side of the electrode again.

Embodiment 2

[0030] Step 1: Replace the electrode;

[0031] Step 2: Apply bentonite on the sides of the upper and lower electrode bases and mix it with water, and then stir it evenly to form a paste. The mixing ratio is 1:3, and the width of the coating is 110mm, and the thickness of the coating is 0.6mm; There is accumulation;

[0032] Step 3: Turn on the machine and start working;

[0033] Step 4: Use the cleaning tool to clean the welding slag when the machine is shut down to replace the work roll, and the cleaning process improves the efficiency by 2.8 times;

[0034] Step 5: Use a cleaning tool to clean the welding slag on the electrode. After cleaning the welding slag, reapply the coating described in step 2 on the electrode base and the side of the electrode.

[0035] Cleaning tool comprises handle 1 and cutter head 2, and cutter head 2 is the rectangular trapezoidal shape of uniform thickness, and its lower edge length is 60mm, and upper edge length is 30mm, and thickness is 15mm...

Embodiment 3

[0037] Step 1: Replace the electrode;

[0038] Step 2: Apply 50% 400-mesh emery powder and 50% refractory clay with water on the sides of the upper and lower electrode bases to form a slurry. The paint is 120mm wide and 0.8mm thick. After the paint is painted , proceed to the next step after natural cooling for 1 hour;

[0039] Step 3: Turn on the machine and start working;

[0040] Step 4: Use the cleaning tool to clean up the welding slag when the machine is shut down to replace the work roll;

[0041] Step 5: After cleaning the welding slag, reapply the paint described in step 2 on the electrode base and the side of the electrode.

Abstract

The invention belongs to the technical field of cleaning methods for welding slag after welding is conducted through a flash welding machine, and particularly relates to an electrode welding slag cleaning method and cleaning tool for a flash welding machine. The cleaning tool is used for cleaning the welding slag during the time of replacing working rolls in the shutdown process; and due to the fact that lithium-based grease is smeared, a carbonized film outer layer is formed by the lithium-based grease at high temperature and serves as the welding slag, the welding slag is easy to clean, the effect of periodically cleaning the welding slag can be easily achieved, and the welding seam quality is improved; meanwhile, the usage period of welding machine electrodes is prolonged, and the operation cost is reduced.
