How to make a folding platform for third-generation lean pipe?

How to make a folding platform for third-generation lean management? The following is a technical solution based on the third-generation lean pipe production folding platform, combined with key points of structural design, material selection, and assembly process:

1、 Preparation of materials and accessories
Core materials

Adopting the third-generation aluminum alloy lean tube (recommended diameter 28mm or 43mm, wall thickness 1.2-1.7mm), it has anti rust and anti-corrosion properties, and can bear up to 900kg.
Special hinge components (such as opposing hinges), T-bolts, M6 embedded nuts, and other connectors are required to ensure the stability of the folding mechanism.
Auxiliary tools

Manual cutter (vertical cutting of pipes), file (deburring), hex wrench (fastening hinges).

2、 Key points of structural design
Folding mechanism

Connect the platform body and supporting feet through hinges, and use the lever principle to achieve retraction and extension. This requires verification through three-dimensional mechanical simulation (such as deformation ≤ 0.7mm under 1000N load).
You can refer to the gravity ramp design of LCIA turnover vehicles to optimize the space occupancy after folding.
Load bearing reinforcement

Add parallel double pipes or strengthen joints, and use 43mm diameter pipes for key stress points.
It is recommended to pair the countertop with 2mm thick aluminum alloy sheet, and the cutting size should match the frame.

3、 Assembly process
Cutting and pre-processing

Mark the cutting position of the pipe according to the design drawings, use a dedicated cutter to avoid deformation, and remove burrs from the cut.
Framework construction

First assemble the front and rear feet (adhesive joints), then connect the left and right sides to ensure symmetry.
When installing the hinge, it is necessary to reserve a clearance for movement and control the opening and closing angle by adjusting the screw.
Fixed tabletop

Install support joints at the four corners of the frame, bond the tabletop board, and finally test the folding smoothness.
