Technical improvement and application of C-type steel mill precautions for equipment

A kind of torsion punching method of full-automatic C-section steel machine. Torsion cutting adopts different models of molds to cut the finished products of the corresponding models of full-automatic C-section steel machine. This method can improve the flatness and smoothness of the finished products of full-automatic C-section steel machine after cutting, and realize the integration of punching and cutting at the same time

the full-automatic C-shaped steel machine is a single roll forming unit that can simultaneously produce various specifications of C-shaped purlin products through a set of rolls. The full-automatic C-shaped steel machine is mainly composed of passive loading frame, leveling device, punching device, cutting device after forming, hydraulic station, computer control system, etc. Through the production experience of full-automatic C-section steel machine, our company broke the Convention on the basis of the original full-automatic C-section steel machine production, and made a substantial improvement in technology. Specific improvements are as follows:

one step improvement, adding length measuring device and flying saw. When the pressing length reaches the set length, the flying saw acts and automatically cuts off the profile

two step improvement: add a hydraulic punching equipment for side holes, which can punch four holes at a time, and the flying saw cuts off from the middle, so as to form two side holes at the head and tail of two adjacent sections of full-automatic C-beam machine

three-step improvement, add another equipment for punching middle holes, punch middle holes according to the spacing set by the user during the strip steel pressing process, and 16 middle holes can be punched if it is larger

four step improvement. In view of the requirements of the new fully automatic C-shaped steel machine to punch double holes in the middle of the profile, the side hole 4-hole punching die is changed to a 2-hole die, and the procedure of punching side holes is modified, so that the side hole punching equipment can punch double holes in the middle, and the hole spacing is set by the user, so 8 groups of double holes can be punched if it is large

the full-automatic C-shaped steel machine can be used as the main stress-bearing structure of large and medium-sized industrial and civil buildings, such as the roof load-bearing load and wall flat support of factory buildings, warehouses, locomotive hangars, aircraft hangars, exhibition halls, cinemas, stadiums, and market flower sheds
