3, Machine Features
This Highway crash barrier roll machine is specially designed for
the production of high way crash barrier products for customers.
The production process is as follows: the sheet material processed
by the length of the chamfer is manually placed on the conveying
platform and then introduced into the forming machine by the
conveying platform, and the forming of the workpiece is completed
by the forming roller. After that, it is received through the
The main frame of this equipment is welded by the whole profile,
which has good rigidity and stable structure. In the production
process, it is a bit moving, automatic, backward and other
functions. The electrical system is equipped with an overload
protection device to prevent damage caused by inadvertent overload.
The equipment is mainly composed of a conveying platform, a cold
rolling forming machine, a receiving platform, an electric control
system, a transmission part, and a safety protection part.
1. Conveying platform: used to take over the sheet and introduce
the sheet into the forming machine. The length is 3 meters and the
workbench is powered.
2. Cold Roll Forming Machine: It mainly consists of a guide frame,
a forming part, and a transmission part.
a. Guide frame: It is a guiding device with anti-rolling roller to
ensure that the sheet is straightly centered into the forming part.
b. Forming portion: The forming portion is mainly composed of a
frame, a side plate, a die (rolling) supporting portion, and a
rolling die. 1The frame is welded by profile, the thickness of the
workpiece table is 30mm, the structure is firm, and it is processed
after aging treatment. The deformation is small and the internal
stress is eliminated. 2 The side plates are made of high-quality
steel and finished with a thickness of 45mm. The surface is smooth
after processing. 3 The main part of the mold support part - the
rolling shaft is 45# steel, refined and refined after quenching and
tempering, the matching part is accurate in size, and the bending
and deflection performance is good. Its shaft end working bearing
adopts famous domestic and foreign manufacturers' products to
ensure the stability of work and its working life. 4 Rolling molds
use advanced foreign COPRA software for CAD design. The material is
Cr12MoV steel, the surface hardness after heat treatment reaches
HRC60-62, and the wear is extremely small. After strict procedures
and processes, it is processed by precision CNC machine tools. The
dimensional accuracy is up to IT6~IT7, the surface roughness is
above 1.6μm, the dimensions are accurate after forming, and the
forming work surface is beautiful. The rolling die device is
mounted on the rolling boring shaft and is locked by the left and
right nuts to be locked and locked, which is stable and reliable.
After the reasonable design of the whole machine, the forming roll
is gradually formed by 16 steps. After forming, the product has
accurate dimensions and beautiful surface.
c. Transmission part: It is the conveying part of the forming power
of the equipment. The power is transmitted by the motor to the
driving wheel through the reduction gearbox. The driving wheel is
driven by the gear to make the upper and lower rolling turns
3. Receiving product platform: used to take over the formed sheet,
the length is 3 meters.
4. Electrical control system: The whole machine adopts high-quality
electrical actuators, reliable contact and disconnection action,
ensuring the coordination of the whole system, and the installation
layout is reasonable and stable.
