The the tramcar tricyclic chain present invention relates to a whole forging manufacturing process chain tricyclic, tramcar tricyclic chain by six fire times forging quality steel: tramcar tricyclic the chain first fire times: upsetting pull side flattening pressure early, forging boring end ring, a large double-edged chop Central, small double-edged chop side ring, point the red punching red edges scrap, separate chain ring; tramcar tricyclic the chain second fire times: to go in the end ring more than expected, check the flash deburring; the third fire times: forging boring end of the half-ring, go to the inner and outer ring flash burr; fourth fire times: forging stuffy full end ring, go inside and outside burrs check deburring; the fifth fire times: forging stuffy middle ring, go inside and outside burrs, check deburring; the sixth the fire times: precision forging tricyclic, go to each ring burr go side exocyclic fly, check deburring; tramcar tricyclic chain process and welding process, the technical indicators significantly better than welded chain, the whole forging tricyclic chain fibrous tissue continuous performance test results show that its impact, tensile, bending performance is higher than the standard requirements, product performance safe and reliable. 30kg Road plywood hydraulic Bend Vertical switchman tramcar the tricyclic chain products by forging molding, using high quality materials in the ring with a special welding process, forging, and strict surface flaw detection to ensure the security of the use of the product, the mine the car the tricyclic chain products applicable to mine coal mine, the mine car the tricyclic chain, ore and other substances transport the tramcar connection, tramcar tricyclic chain periodic inspection by national security inspection center Fushun coal mine safety inspection qualified products . The tricyclic chain forged by a material through nine. The tramcar tricyclic chain apply to the transportation of coal gangue materials the tramcar and forestry timber transport connection, under the premise of coal mine security procedures also apply to mine people join. Application: Mine connecting material: high-quality alloy steel standard: ISO, DIN, BS, GB, MT standard strength grade: C grade, B-grade security guarantees: proof load is 2 times working load code, size and mechanical performance specifications width minimum weight test load of the radius of the arc experimental elongation minimum segment breaking load minimum breaking segment elongation within wide outside width 22 × 105 40 87 41 2.9 70 2 370 15 26 × 118 46 102 48 4.6 100 2 520 15 28 × 120 48 108 51 6.7 110 2 610 15 30 × 120 48 112 53 7.8 120 2 670 15 30 × 130 55 119 56.5 6.9 120 2 670 15 32 × 140 58 126 60 9.9 140 2 790 15 34 × 147 64 136 65 10.1 160 2 890 15 38 × 145 80 160 77 13.65 200 2 1110 15 Jining City Zhuoxin Mining Equipment Co., Ltd. adhering to the bold and solid, in the Shandong Province, are invited to visit our company experts, leadership, guidance, enlighten and look forward to your sincere cooperation, "the pursuit of excellence" will always be our theme, we will make every effort to create efficient, and strive to the state-of-the-art technology, excellent product quality, provide multi-faceted services for coal mining enterprises.
