Mechanical Structure of Friction screw press
Presses, also known as: hydraulic machine, hydraulic machine.Pressure consists of four parts: the pressure on the four column hydraulic press; combination of control cabinets; electric heating system and insulation device; mold delivery gantry. The composition of the integrated design, so generous, beautiful, compact structure, simple and reliable operation, easy maintenance.
Four column hydraulic press
Press should have a reliable structure of the anti-deformation ability of the hydraulic station on the position, the pressure row to set the mold lifting connection device, the hydraulic station and the platoon has a removable dust cover. The workpiece can be out of the direction of the length (3000) direction. Technical parameters are as follows: nominal pressure 190T; effective table area 3000 × 750 mm2; pressure row moving speed 75 ~ 100 mm / s; maximum opening and closing distance 550 mm (without heating plate); dwell time 8h (workpiece 130 ℃) ; Press base height of 0.5 ~ 0.55m; platoon and the base of the flatness of 0.2 mm; pressing the base pressure with the average gap ≤ 0.25 mm (not less than 10 measuring points).
Heating system is made of steel heating plate, heating pipe, insulation layer. Heating plate points up and down two, respectively, with the press base and pressure row fixed connection, and easy disassembly, heating plate made of high quality 45 # steel quenched and tempered. Place heating tube and thermocouple in the heating plate. Thermocouple installation and reliable, easy demolition. Heating plate technical parameters: plane size 3050 × 650 mm2; flatness 0.2 mm; measuring point arrangement: 3:00 on the board; the next board 6:00. Heating tube shell material is stainless steel, working voltage 220V. Unilateral qualifying, the number is a multiple of 3. Electric heating tube replacement easy and reliable. Wiring protection. The insulation layer is arranged between the heating plate and the base (or the pressure plate), the heat insulation side plate should be arranged around the heating plate, and the material with good heat insulation performance should be used. The plane size is equivalent to the heating plate, and the thickness is not less than 20 mm.
Cabinet press action and temperature of the cabinet. Cabinet panel on the instrument and switch; power switch, light, voltmeter, ammeter; press action buttons and lights; pressure indicator; heating switch and indicator light; digital temperature regulator (accuracy ± 1 ℃); Temperature alarm device, the maximum temperature of 180 ℃; heating rate of 1.7 ℃ ~ 2.5 ℃ / min; temperature uniformity ± 3 ℃, the heating power of each phase power balance; temperature regulator on the corresponding real-time temperature control area, When all reached the set value ± 3 ℃, the timer time to reach the set time, the temperature control system can be automatically set according to process temperature or power.
The gantry is a roller-loaded structure on the top with one end attached to the press base (removable) and one end resting on the floor (height adjustable). Carrying capacity of 3T; a high degree of rolling the upper surface flush with the lower heating plate; plane size (2800 ~ 2900) × 750mm2 (available part); insulation board on the press platoon and the base around to reduce the mold heating process The heat loss, with aluminum (or stainless steel) and insulation materials. For ease of placement can be divided into several pieces.
