PE plastic pallet hydraulic press_630 tons hydraulic press
Plastic pallets are made of thermoplastics such as PE\PP, plus some additives to improve performance, through hydraulic presses, molds and other processes. The 630-ton four-column hydraulic press produced by Tengzhou Hunter Machinery, a Chinese hydraulic press manufacturer, is a molding compound molding equipment, which is suitable for the pressing and molding of chucks, plastic pallets, building mold shells, and other plastic products. 630 tons of four-column hydraulic press molding plastic products, can be designed and customized according to the needs of different work surfaces, openings, strokes, configurations, etc. The molding speed is fast, the product quality is good, it has high strength, high rigidity, and a very long service life. Generally, the service life of the blow molding tray can reach 5~10 years, and it can work stably in the environment of -40~40℃.
Plastic pallets are suitable for chemical, petrochemical, food, aquatic products, feed, clothing, shoemaking, electronics, electrical appliances, ports, docks, catering, biomedicine, mechanical hardware, automobile manufacturing, petrochemicals, three-dimensional storage, logistics and transportation, Warehouse handling, storage shelves, auto parts, beer and beverages, electronic appliances, textile printing and dyeing, printing and packaging, logistics centers and other industries.
The 630-ton plastic pallet hydraulic press adopts the structure design of three beams and four columns, and the whole machine is designed by computer finite element analysis; the sliding beam of the plastic pallet hydraulic press is thickened, and the distance between the sliding beam and the guide sleeve of the column is lengthened, which increases the operation of the sliding beam. The stability of the hydraulic press improves the accuracy of the hydraulic press; the column is made of high-quality round steel, and after being polished by a lathe, it is subjected to lathe rough grinding, quenching, cylindrical rough grinding, and chrome plating. Grinding treatment greatly improves the surface hardness and smoothness of the column, reduces the wear during transportation, assembly and use, and prolongs the service life. In order to improve the processing efficiency and processing accuracy of plastic pallets, the plastic pallet hydraulic press is equipped with PLC control system, servo control system, grating protection device, etc.
Design features and functions of 630 ton plastic pallet hydraulic press:
1. The hydraulic press adopts the integrated system of cartridge valve, and the electrical appliance adopts PLC programmable program control.
2. The pressing actions are generally: slide block down, decelerate down, slow pressing and forming (sometimes need to be exhausted), pressure maintaining, pressure relief, slider micro-return, fast return to the upper limit, ejection cylinder and slow ejection The cylinder is quickly topped, the cylinder is ejected and returned, and the material is manually retrieved and fed.
3. The action of the 630-ton plastic pallet hydraulic press consists of a high and low pressure combined pump, which is realized by self-weight downward oil filling during rapid downward movement, thus greatly reducing the power required in the rapid stage. After the pressure reaches a certain value or a certain set position, the low-pressure pump releases the pressure and the high-pressure pump works, thus forming a low-speed pressing to facilitate the material to flow fully and discharge the cavity.
4. The superior configuration of the main components of the plastic pallet hydraulic press greatly improves the reliability of the product. For example, the hydraulic parts use products from well-known hydraulic parts factories, and the PLC uses well-known products at home and abroad.
5. The fuselage of the 630-ton four-column hydraulic press is a four-column structure, and the force-bearing parts are optimized with a beautiful appearance and economical application.
6. The slider can realize two control modes of fixed stroke and fixed pressure, with functions such as pressure holding and delay; the working pressure and stroke size can be adjusted within the specified range according to the process needs.
7. The power system adopts oil-immersed vertical pump set. Reduce noise, good oil absorption effect.
8. The pressure gauge adopts shock-resistant pressure gauge and is equipped with a pressure gauge door, which is convenient for maintenance.
The specific process flow of the molded plastic tray: feeding (adding the molding compound into a preheated steel mold), clamping, filling (the molding compound flows under pressure and fills the entire cavity), curing (at the set pressure and Keep it at the temperature for a certain period of time and then fully solidify), open the mold and take out the plastic tray product.
