Valve processing welding forming tool
The processing characteristics of valve processing welding forming tools are many hole steps, many forming surfaces, many intersecting holes, strict requirements for size accuracy, and high requirements for hole surface roughness and straightness.
SS Shuoshuo has excellent capabilities in valve body processingSolid carbide forming tooland welding carbide forming tools and machine-clamped stepped valve body processing tool bars, multiple hole processing tools are combined into one, which can meet the requirements of size accuracy and surface roughness of stepped holes. He has rich experience in tool application for machining sealing surfaces of valve blocks cartridge valve holes.
Valve processing and weldingforming toolThe hardness of the valve body material can reach HRC53-65 degrees. This material has high hardness for cutting, is prone to chip accumulation, and has high cutting resistance. The orifice forming profile size is complex, with 3 sections in the forward direction and 5 sections in the reverse direction, and the surface accuracy requirements are high, reaching Rz ≤ 8µm;
In order to simultaneously realize the machining of multiple holes with different diameters in complex hole systems, reduce the frequency of tool changes, realize the machining of complex hole systems in high-power fuel injection pump bodies, improve the machining efficiency and quality of hole systems, and meet mass production requirements. Welding alloy is selected for the cutting parts of the composite combination tool, and the outer diameter of the multi-segment blade is from small to large. In order to greatly improve the processing efficiency and meet the design requirements of complex hole systems, a chamfer is designed at the opening of the hole, and the tail of the cutting edge of the branch blade corresponding to the hole is provided with a chamfer consistent with the chamfer of the hole, realizing the simultaneous processing of the hole and the chamfer improves processing efficiency. Reduce the number of tool changes to improve machining accuracy.
Valve processingWelding forming toolThe size accuracy of the valve body directly affects the processing accuracy of the valve body. It is necessary to ensure that the size, shape and position tolerances of the tool meet the processing requirements.
The hydraulic valve of the injector changes a fixed amount of fuel from a liquid state to a mist, and then mixes it with air; the electronic injector generally has a spool, a spring post, a valve core, a spring, and a valve seat (including a sealing steel ball). The spring post is in the spool and bears against one end of the spring, and the other end of the spring bears against the valve core. There is a coil external to the electronic injector, and its working principle: When the coil is not electrified, the valve core of the electronic fuel injector presses against the sealing steel ball under the joint action of high-pressure gasoline and the spring, and the oil passage is blocked. When the coil is electrified, magnetic force is generated, and the valve core acts, and the high-pressure gasoline passes through the sealing steel ball. Spray out. Electronically controlled fuel injector is a precision device with very high machining accuracy.
Valve processing and welding forming tools process the plunger hole system in key parts of the pump body. The processing quality of the plunger hole system directly affects the correct relative position of the plunger sleeve, the plunger and the cam, and is the key to ensuring regular and quantitative oil supply. For this reason, the processing quality of the porous system of the installed plunger is crucial to ensuring the reliability of the diesel engine.
Accuracy of valve processing and welding forming tools: The size of the tool should be designed strictly in accordance with the processing requirements of the valve body to ensure the matching accuracy between the tool and the valve body.
