1、 Choosing the right materials saves 80% of the trouble in the later stage
We use 6061-T6 aluminum alloy (compliant with ASTM B221 standard) – which is almost the “golden material” for industrial connectors:
1. 轻的: With a density only one-third that of steel, it can reduce energy consumption when used in robots and automation equipment;
2. Strong enough: After T6 heat treatment, the tensile strength reaches 310MPa, which can withstand the vibration and load of equipment operation;
3. Easy to process: Excellent cutting performance, capable of achieving a “mirror level” surface (Ra ≤ 0.8 μ m) without the need for additional polishing;
4. 耐腐蚀: The natural oxide film isolates the air and is not easily rusted in outdoor or humid environments.
2、 CNC加工: perform “fine carving surgery” on the valve body
To process this aluminum alloy valve body, it is necessary to rely on a multi axis CNC machining center to show great skills. The process is like “carving precise fluid channels for metal blocks”:
The processing steps are as follows:
1. Digital programming: Use Mastercam software to import customer 3D drawings and simulate tool paths – such as avoiding weak areas in the central groove, optimizing hole sequence, and avoiding billet deformation during processing.
2. Blank clamping: firmly fix the aluminum alloy blank on the machine worktable to ensure that it does not shift or deviate during processing.
3. Rough machining to eliminate redundancy: Use a hard alloy end mill to first cut off the excess part of the blank and shape a rough outline – aluminum alloy has good machinability, but this step also needs to be carried out steadily, controlling cutting parameters to avoid blank deformation.
4. Fine machining carving thread: Replace with a more refined forming milling cutter or ball end milling cutter to activate the fine carving mode. Multi axis linkage (such as four axis and five axis) allows machine tools to flexibly adjust angles, gradually milling out complex structures such as internal flow channels, interfaces, external installation bosses, 螺纹孔, 等. of the valve body.
5. 表面处理: 加工后, tap and chamfer the holes of the valve body, remove burrs and polish the surface, and then install sealing rings and connect pipes tightly without water/air leakage.
6. Full inspection or random inspection: Use a coordinate measuring machine (CMM) to scan all key dimensions and attach an SGS report – 例如, if the installation hole spacing error is less than 0.01mm, ensure a tight fit with the customer’s other components.
3、 Structural features=the ‘design password’ for solving problems (key focus!)
每个 “protrusion” 和 “槽” of this part is not redundant, it saves customers a lot of trouble:
1. Central circular groove: positioning without deviation by a millimeter
Design purpose: to accommodate shaft components (such as servo motor shafts for robot joints) or small sensors;
Advantage: The inner wall of the groove has a 0.5 ° taper, and the parts will automatically align when placed in, without the need for manual angle adjustment – assembly time is reduced by 30%!
2. Standard holes around: No need to draw drawings anymore
4 M5 threaded holes+6 countersunk mounting holes: all processed according to ISO 2768-m standard;
Advantage: Customers can directly fix with standard bolts/screws without the need for mold making for matching fasteners – saving costs and time.
3. Three support arms at the edge: invisible strength bonus
Shape: Triangle (the most stable structure), extending 3mm outward from the edge of the disc;
Advantage: When the part is subjected to lateral load, the support arm can distribute the force to the entire disc, avoiding “single point fracture” and thus extending the service life by 2 次!
4. Side protrusion+middle small hole: hidden function super practical
Two positioning pin holes on the side (diameter Φ 4mm): quickly connect with the pins of adjacent components without the need for blind installation;
Middle Φ 3mm through-hole: can be used to thread signal wires or ventilation pipes, avoiding cable entanglement inside the equipment – engineers no longer have to squat in the machine to tidy up wires!
4、 Part function:
This component has the following functions for reference:
1. Precise on/off control: Like an intelligent switch, it can enable the fluid to turn on and off as needed according to device requirements.
2. Fine flow regulation: Similar to an intelligent faucet, it can precisely control the flow rate of fluid to meet the fluid needs of different operating conditions of the equipment, such as opening the supply when a large flow rate is required, and flowing fine water for a long time when a small flow rate is needed.
3. Orderly flow guidance: Similar to intelligent traffic police, it guides fluid to flow in the prescribed direction, ensuring that all components of the equipment can obtain fluid as needed.
最后, I would like to say:
Are you an engineer? Are you looking for a connector that doesn’t require any design changes?
Are you a purchaser? Looking for a supplier with stable quality, fast delivery time, and reasonable price?
This aluminum alloy valve body may be the answer you are looking for.
