Product Specification

                    Z purline with multi-punching for RV bottom beam making machine

Z purline with multi-punching for RV bottom beam making machine is designed to make a kind of Z profile with more than 10 types punching and with 5 degree bending for RV bottom beam, car beam rolling machine. Here we will take the drawing profile for example to show you how the machine is designed:

Z purline with multi-punching for RV bottom beam application: 

Z purline with multi-punching for RV bottom beam making machine design:

Z purline with multi-punching for RV bottom beam making machine working flow:

The process flow of the production line: 5T feeding rack → leveling machine → punching (8 sets of mold frames, about 45T, 12 sets of molds with different cross-sections need to be replaced by themselves) → servo feeding → 18 sets of rolling forming (spindle diameter 80mm) → straightening → hydraulic cutting → pneumatic automatic unloading. The entire process is automatically completed.

Part 3: Main Rolling forming part:

5-1. Forming machine frame: shot blasting or vibration treatment after welding of high-quality profile steel, CNC gantry milling processing, and each pass of the bottom surface of the memorial archway

There is a positioning keyway to ensure the parallelism of the roller shaft.

5-2. Structure of guide feeding rack: lateral handwheel, guide roller quenching treatment. When left and right guidance is set at the feeding port of the host, the raw material sheet enters the host through left and right guidance on both sides, keeping the raw material sheet in the correct position with the roll forming system. The guidance position can be adjusted by a manual screw mechanism, and the left and right are independently adjustable

5-3. It is formed by using 18 sets of horizontal rollers and a series of vertical auxiliary rollers. The roller material is Cr12MoV and is subjected to vacuum heat treatment, two tempering processes, and a hardness of HRC55-58.

5-4. The spindle has a diameter of 85 and is made of 40Cr material. It has undergone quenching and tempering treatment (HB220-260), CNC machining, and external ultra precision grinding. Two sets of Harbin tapered roller bearings 30212 are equipped for transmission, and one set of Harbin cylindrical roller shaft 6212 is equipped for operation.

6.1. The main motor is a 18.5KW motor with variable frequency speed control.

6.2. The driving wheel adopts gear transmission, and the rollers adopt gear transmission. The hard tooth surface gear reducer (ensuring transmission synchronization) has a gear module of m=5. The main side plate is 53mm thick, and the auxiliary side plate is 33mm thick, ground on six sides, and drilled.

7. Straightening: 5 straightening wheels are used for straightening (2 for the upper wheel and 3 for the lower wheel).

8. Hydraulic cut-off system:

8-1. Hydraulic system: The system has unloading protection function, hydraulic mold frame 45T; hydraulic system power: 7.5KW.

8-2. Formwork: The enclosed height of the formwork is 300mm, and the maximum stroke of the oil cylinder is 100mm.

8-3. There are 2 linear guide rails at the bottom of the mold frame, each of which uses 2 sliders. The mold frame is pushed back by a cylinder.

8-4. The mold material is Cr12MoV, heat treated to HRC55-62.
