Four-column hydraulic press structure
1. The main engine is a three-beam four-column vertical structure. It consists of a fuselage, a master cylinder, a stroke limit device, a lubrication device, a hydraulic power system and an electrical system. It is composed of upright column, lock nut, guide sleeve, etc. The slider moves linearly up and down along the four columns under the drive of the oil cylinder.
2. The upper beam, slide block and worktable are made of whole No. 45 cast steel and have good rigidity and strength.
3. The main column is made of No. 45 round steel and is chrome-plated to ensure that it will never rust. The sliding sleeve (guide sleeve) is made of wear-resistant cast iron and embedded with PTFE wear-resistant material to prevent the column from being pulled and has good performance. The anti-eccentric load capacity is excellent, and the lubrication of the friction pair adopts a hand-operated oil injection pump device, which has the characteristics of centralized lubrication and smooth oil supply.
4. The hydraulic cylinder is a piston type structure. The key seal of the cylinder adopts the national standard sealing ring with good anti-aging and sealing performance. The cylinder body adopts 45# grinding pipe, with good inner hole finish, and the large cylinder body adopts 45# forging steel parts. , The plunger is 45# round steel, and the surface is chrome-plated, which is rust-proof and wear-resistant.
5. The hydraulic pipeline adopts cold-drawn seamless steel pipe, which is installed after welding, polishing, pickling, neutralization, phosphating, cleaning, drying, oiling, etc. The pipeline layout is clear and neat, and the high-pressure pipe The bending radius is standardized, the high and low pressure pipes are clearly distinguished by color, which is easy to maintain, and the diameter is larger than 25. The diameter is flanged to reduce the occurrence of oil leakage of the whole machine.
