Flower pattern and roll positioning design for the cage

Process design for cage roll forming of an ERW pipe with the diameter of 377 mm is presented as another case for demonstrating the proposed methods. The material is X-60 steel with 12.7 mm thick. The input parameters for flower design are listed in Table 6 , and the designed forming flower is presented in Fig. 24 .

Plate Rolling Formula - Mechanical engineering general

Jan 31,  · windseaker1 Sorry for being late getting back, yes the bend formula works for rolling as well, when you roll a plate you are bending it on a large radius, the metal still has to shrink on the inside of the neutral line and stretch on the outside.To get a finished diameter that you want, you have to compensate by adding or subtracting part of the metal thickness from the neutral line.

The formula for successful punching

While the first step in successful punching is to pay close attention to the quality and features of punching tooling, other factors come into play. Punched slugs are clues, and examining them can reveal whether the punch and die clearance is too loose or too tight

Tube drawing is very similar to bar drawing, except the

style, tool design and lubrication can be very critical. Problems with friction in tube drawing are minimized in drawing with a long . mandrel. The mandrel consists of along hard rod or wire that extends over the entire length of the tube and is drawn through the die with the tube. In this design

Introduction to Seamless Pipe Manufacturing - The Process

Jul 24,  · The design of the piercer rolls causes the metal to flow along the roll and over a piercer point as it exits the process. The piercer point is a high-temperature, water-cooled alloy tool designed to allow the metal to flow over it as a pipe shell forms from the rotary process.

Rubber Compounding - an overview | ScienceDirect Topics

The mill rolls are hollow to allow flow of coolant for control of roll and stock temperatures. A number of safety features are incorporated into mill design, including shutoff switches and brakes to stop the rolls quickly, means to move the rolls apart, and guards to keep hands and tools away from the nip area.

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll - body and necks - have to be considered as normal parts of designed components under high
