Design principle of three-dimensional garage wave plate cold forming production line:

This design is reliable and easy to maintain, and the standardization, generalization and normalization of service life of parts are limited. The province of investment, the high standard of key parts, the use of auxiliary parts, the easy interchange of rolls and the principle of unified standards.

Wave plate cold bending forming host parameters:

(1), 19 main rolls,  1 straight head, 1 set of guiding device;

(2), drive Motor power: 18.5KW;

Compressed cold-formed mainframe: fuselage, archway components, guides, installations, alignment devices, transmission systems, etc.

Airframe, archway components:

The fuselage part is the main part of the mill, and the rest of the components are mounted on the fuselage, which are welded by steel and steel plates. After all, stress relief treatment. Each joint surface and mounting surface are finished and the mounting surface is machined with a positioning keyway for precise positioning and convenient installation, ensuring the parallelism between the spindles of each group and the perpendicularity with the rolling centerline.

The archway components are the main working part of the machine. There are 19 sets, which are installed and fixed on the fuselage from front to back. The assembly mainly consists of front and rear arch frame, upper and lower main shaft, upper beam, upper shaft lifting and adjusting screw, front and rear bearing support and spindle bearing. The rear arch frame is fixed on the fuselage and is the support reference for the upper and lower spindles; the front arch is detachable for easy replacement of the assembly rolls. The upper and lower main shafts are mounted on the bearing support through bearings. The bearing support can be adjusted along the guide surface of the arch window by adjusting the lead screw to adjust the distance between the upper and lower shafts for the installation of different diameter rolls. The upper and lower spindles are made of 40Cr round steel of ф85mm. The processing technology is as follows:

Roughing and tempering treatment HB240-280-finishing car-milling keyway-grinding machine to meet the drawing size.

B: Guide device

The device consists of a bracket, a side guide roller, and an adjustment device. The position of the side guide roller can pass through the left and right screw rods. Make lateral adjustment to ensure accurate and stable sheet introduction.

C, calibration device:

The calibration device is composed of a base, a lateral adjustment seat, a vertical adjustment screw, a column, a horizontal base, a rotary disk, etc. at the end of the machine; It can realize the horizontal traverse, vertical lifting, and the adjustment of the core rotation to achieve the lateral bending of the workpiece, the upper and lower bending and torsion correction requirements.

D, Roll:

The roll is a mold for forming a sheet, and the strip is continuously rolled and deformed to make it a profile of the cross-sectional shape and size that meets the requirements of the drawing. The position of the rolls on each axis is adjusted and fixed by the nuts at both ends of the spindle. The rolls are made of GCr15 and quenched HRC 58-62. The roll processing process is as follows:

Sawing machine blanking-forging to blank size-spheroidizing annealing-roughing-drawing keyway-total quenching-grinding both ends to size-grinding hole to size-NC The outer diameter is machined to the required dimensions of the drawing.  

E, transmission system:

This system is mainly driven by a KC series 18.5KW motor directly connected spiral bevel gear reducer; For each power shaft, the transmission system is compact, stable and reliable, and is ideal for low-speed transmission.

Hydraulic punching and setting mechanism:

The hydraulic punching and cutting mechanism consists of a traveling trolley, a pneumatic clamping mechanism, a hydraulic punching machine, a hydraulic cutting machine, a punching die, and a cutting Mold, oil cylinder, 11KW hydraulic station, etc. When the length of the profile reaches the position of the meter hole, the pneumatic cone pin Sliding into the hole, and the pneumatic clamping mechanism acts to ensure that the traveling trolley and the profile are synchronized, and the punching machine and the cutting machine act to complete the punching and cutting of the profile. After the cutting is completed, the taper pin returns to the position and the clamping is loose. Open, return to the cylinder tow the car back, ready for the next work cycle. Cut the mold for Cr12MoV material, quenching hardness HRC58-62; profile length mechanism consists of pallet rack, hole measuring and length mechanism.
