Development of a seven-axis linkage and tandem machine tool


There are many sliding friction pairs in the hydraulic excavator. Because the sliding friction pairs of the excavator bear heavy loads and the working conditions are relatively bad, the relative sliding friction pairs are easy to fail. However, most of the failures are not fractures, but different forms of wear on the contact surface or surface. In view of the fact that the excavator pin shaft is prone to adhesive wear and fatigue wear, we use high-strength alloy structural steel 42C; M as the pin material after quenching and tempering, surface after high-frequency quenching, EDM surface strengthening, the surface is deep . The white tungsten-cobalt hard alloy reinforced layer of 1~.3 has a hardness of up to HRC74 or higher. by. The processing efficiency is very close to that of the NX154 blade special machine produced by Swiss STELARG. Use the on-line machining accuracy measurement function of this machine to measure the G106-level guide vanes and the blade shape file. A hard alloy having a higher hardness is used as the tool electrode 11, and the pin 12 is used as a negative electrode to alternately short-circuit and open the surface of the positive and negative electrodes to perform electric pulse discharge. The energy stored on the capacitor in the C line forms the spark or tool name and specification. The cutting amount is the number of the process name. The cutting speed is the roughing degree. The concave arc 50 square shoulder iron knife rough processing back arc 50 square shoulder iron knife rough machining concave arc two Side entry and exit side 32 corn milling cutter concave arc clear root 16 ball end milling cutter back arc clear root 32 corn milling cutter finishing steam channel 32 copy milling cutter comparison machining error is 0.02mm to achieve high machining accuracy. Subsequently, free-form surface parts such as the overall marine propeller are machined.

Wire Mesh Storage Basket

Wire mesh basket material:

Process basket series mainly use Stainless Steel Wire Mesh, using electrolytic polishing technology for surface treatment, surface bright as a mirror, and stainless steel wire, low carbon steel wire, low carbon steel wire, copper wire.

2, Wire mesh basket processing technology:

Steel wire mesh : woven, features: hardness, tension, wear-resistant firm. Material from no. 45 steel wire rod into no. 23 wire [0.61 mm] above all kinds of wire, used for mining, metallurgy, construction, medicine and other industries. Specification: 6-38 mesh, wire diameter: 0.61-0.132. Through bending to bend into a variety of crafts, plain weave, surface can be polished, diffuse plastic, plastic spraying, coating, according to customer needs to make a variety of color crafts.

3, Wire mesh basket advantages and characteristics:

Smooth surface, no rust, corrosion resistance, non-toxic, health, environmental protection, beautiful, durable.

4, Application for Wire Mesh Basket:

Medical disinfection, pasta, meat barbecue, living flower basket, fruit basket, vegetable basket, dish basket, cooker rack, all kinds of supermarket basket, turnover box; Hotel drinks, food racks; Office paper baskets, paper baskets, books, newspaper racks, pet cages, etc. Wire mesh deep processing products net basket on top is in woven metal mesh or plate mesh and metal wire as the raw materials, after welding forming, surface passivation, polishing, beautification, such as technology, produced by mechanical and artificial, mainly used in the kitchen, hotels, shopping malls, supermarkets, office, indoor decoration, bathroom, mechanical shield, electrical ventilation, breeding, and many other industries.

1. All stainless steel 304, 316 stainless steel, corrosion resistance, low bacterial adhesion, long service life;

2. Side hole stainless steel punching plate, effectively prevent the end of the instrument with the pointed out;

3. Top round wire top welding design, smooth surface without sharp corners;

4. The bottom of the welding net, to facilitate the penetration of cleaning liquid or steam, to ensure the cleaning effect;

5. Invisible movable handle design, easy to aseptic operation;

6. Overall electrolytic polishing treatment, bright surface, non-toxic and tasteless;

7. Various specifications can be customized to adapt to different sizes and shapes of instruments;

8. Cover can be added, the size of the hole can be produced according to user requirements;

9. Support wire can be added at the bottom to enhance product strength.
