The counterweight block heat press machine is a hot-pressed elevator counterweight block that we produce for our customers to press the elevator counterweight block. We can provide a complete line of elevator counterweight blocks. Die-casting equipment 2000 tons 2500 tons 3000 tons elevator counterweight hydraulic machine elevator counterweight raw material is made of iron powder, iron filings and other scrap scraps from steel mills and pressed by machine counterweight molds. The cost of the counterweight pressed by this process is lower than that of the original customer using the steel plate to make the counterweight iron. The extruded density is the same as that of iron, between 6.5-7.2. The 2,000-ton, 2,500-ton, and 3,000-ton hydraulic forming press machinees for pressing the counterweight are all designed with a four-beam and four-column structure.
The shape and thickness of the counterweight pressed by the 2,000-ton, 2,500-ton, and 3,000-ton hydraulic forming press machine can be designed according to predetermined requirements, and the unit volume density can reach more than 6.5. This process can completely replace the traditional elevator counterweight production process.
Elevator counterweight production process, wrought iron scraps, steel scraps, sponge iron, iron oxide and other scrap metals are crushed by a special forced metal crusher, and pig iron scraps, steel slag particle steel, and slag powder are passed through scientific formula. It is sent to a thermal control furnace (rotary kiln) for preheating and drying, heated to 600°C-1000°C for deoxidation and impurity removal, and then enters a special high-temperature metering device for weighing and measurement in a pre-dissolved state (the accuracy can reach ± 0.5kg), send the material into the customized mold of the hot pressing system with uniform distribution value and large tonnage of the hydraulic distribution system, and then use the die-casting equipment 2000 tons 2500 tons 3000 tons elevator counterweight hydraulic forming press machine to hot-press into elevator counterweights, making The shape and thickness of the completed counterweight can be designed according to predetermined requirements, and the unit volume density can reach more than 6.5. This process can completely replace the traditional production process of elevator counterweight, such as casting, steel plate cutting, model pouring, etc. This project is a solid waste recycling project, promoted by the state, and has been tested by the market.
Technical advantages of die casting equipment 2000 tons 2500 tons 3000 tons elevator counterweight hydraulic forming press machine:
1. Wide range of raw material sources The raw materials used are: pig iron filings, wrought iron filings, particle steel, iron fine powder, etc., which can be used as raw materials for the production of counterweights.
2. The forming quality of the elevator counterweight is controllable. The forming quality of the elevator counterweight is controllable, which can be divided into controllable shape and controllable weight. The forming shape is mainly determined by the customized mold, which can be customized according to customer requirements. Made of material, the thermal expansion coefficient is small, the quality of the finished product is stable, the surface finish is high, and the durability is durable. The weight of a single block is controlled within ±0.5kg.
3. High thermal efficiency of the system The system adopts the direct circulation of exhaust gas and the recovery and utilization of waste heat, which greatly improves the energy utilization rate and greatly reduces the fuel cost of system operation.
4. Easy to operate. It adopts automatic control of the whole production process and all-round video supervision without dead angle.
5. System environmental protection The exhaust gas of the temperature-controlled furnace adopts the first-level cyclone dust removal, the second-level exhaust gas cooler sedimentation and the third-level bag dust removal system, and the dust removal efficiency reaches 99.9%.
6. The system accident rate is low. Through simulation calculation, the smoke inlet of the system adopts a lower design temperature, and special measures are adopted to adjust it according to the raw material conditions. Therefore, the working temperature level of the furnace lining will not exceed the melting temperature of impurities, and there will be no sticking ring accident. In addition, the refractory material has no damage to the sticky ring, and the system operation rate is greatly increased.
7. The system process is simple, the die-casting equipment 2000 tons 2500 tons 3000 tons elevator counterweight hydraulic forming press machine has good running stability, the system process design is very simple and smooth, the adjustment method is flexible, and the phenomenon of supercooled and superheated material circulation will not occur, and the system runs High stability.
Die casting equipment 2000 tons 2500 tons 3000 tons elevator counterweight hydraulic forming press machine Product structure:
1. Host:
(1) The fuselage chooses a three-beam four-column structure: it is composed of upper and lower beams, sliders, work surfaces, columns and other components. The upper and lower beams, sliders and worktables are made of high-quality integrated steel castings, which have high strength. The column of the pig farm breeding insulation cover molding machine is high-quality 45# steel, and the surface is medium frequency quenched and chrome-plated.
(2) Select the piston cylinder for the oil cylinder. The cylinder body is made of high-quality No. 45 steel. The surface of the piston rod is processed by intermediate frequency quenching, which has high hardness and long service life. High-quality sealing rings are selected for the main seals of the oil cylinder to ensure safe and reliable sealing.
(3) There are T-shaped grooves on the work surface and the slider, which is conducive to the installation of the user’s mold.
2. Hydraulic system
(1) The hydraulic system chooses a cartridge integrated system, which has sensitive behavior, safe and reliable operation and good sealing performance.
(2) The fuel tank is welded by steel plates, and the closed fuel tank is selected, the oil suction area and the oil return area are separated, and the fuel tank is equipped with a cleaning window and an oil drain plug, which makes cleaning and oil change convenient.
(3) The oil pump suction port of the hydraulic forming press machine is equipped with a straight-through oil suction filter to ensure the cleanliness of the oil and the service life of the oil pump and valve.
3. Electrical control system
(1) A separate electric control cabinet is equipped with electrical control systems such as air switches and relays.
(2) All kinds of alarm signals, limit switches and press behaviors establish program interlocking.
(3) Equipped with a centralized control panel, the necessary control buttons and selection switches are arranged on the panel.
(4) The hydraulic forming press machine selects the PLC programmable controller, and uses the adjustment program to adjust the time sequence and pressure holding time of a single action.
The working method of the elevator counterweight forming hydraulic forming press machine:
1. Jog:
Press the corresponding button to generate the corresponding behavior, release the behavior to terminate.
2. Manual:
Press the corresponding button to generate corresponding behavior until the limit position.
3. Semi-automatic:
(1) Constant pressure control: the sliding beam slides rapidly → slides at a low speed → the pressure is supplied to the upper limit of the electric contact pressure gauge DJ, and then the pressure is maintained and delayed → the pressure is exhausted → the return trip (termination later).
(2) Fixed-range control: sliding beam slides rapidly → slides at low speed → pressurization When the sliding beam encounters the limit switch XK, the signal starts to maintain pressure delay → pressure discharge → return (later termination).
