Urgent! Urgent! Urgent: How to roll 8mm×100mm×100mm stainless steel angle bars using a plate rolling machine in the absence of rolling tools
Thread Content
The equipment manufactured by our factory features two reinforcement rings with a diameter of 2600 mm, made of stainless steel angle iron. It is very difficult for us to directly wind the parts using a winding trigger without special tools; we would appreciate it if our respected teachers could suggest any good methods. Thank you! !
Thank you for the advice from the teacher on the second floor. However, the angle steel we purchased is already in finished form, and it’s necessary to bend it into an arc using a bending tool. We tried using two pieces of angle steel to form a channel shape, but the result was not satisfactory at all. Let’s see if there are any better solutions suggested by the teacher on the second floor!
Do you have any local heating devices such as spray guns? If it is available, after positioning it properly, use a tool to provide support; then use a spray gun to heat it up. Once it is red hot, use a larger hammer to strike it against the wall of the container, heating it in sections – about 300 mm per section after heating 700 mm. After that, continue heating the lower part. Angle steel becomes quite large once heated red hot; this was exactly the method we used in our factory to create curved reinforcement strips.
Control the direction of the spray gun to avoid burning the container walls and only burn the angle steel.
The 40*4 angle steel rings were formed into a diameter of 3000; they were manufactured as pairs directly, without the use of any molding tools
The suggestions given by the teachers upstairs are excellent. However, our equipment uses N6 material with a plate thickness of 6 mm in a soft state; the cylinder deforms under external forces. Therefore, it is essential that the ellipticity of the reinforcement rings be within standard limits in order to ensure the aesthetic quality of the equipment. I would appreciate any further advice from the experts. Thank you!
4# liuliu8622: Is this okay? If we keep hitting it with a hammer like this, what will be the outcome in terms of the shape of the cylinder? Especially for stainless steel cylinders, might it not look good? It might be better for carbon steel cylinders
I don’t see any other solution; either have it done by someone else outside, or piece it together, or buy the molding tools yourself. It seems like there’s no good solution either.
Stainless steel won’t do this; even carbon steel won’t
When using reinforcement rings, the wall thickness is generally relatively thin. If assembly is carried out while tapping, then there’s no need for reinforcement rings on the cylinder. It is recommended that you outsource the processing rather than trying to do it on your own
