Abstract
The utility model discloses a fly press. Cluster gears are driven by two air-actuated swing cylinders. A flywheel and a cap nut are driven by a screw rod arranged on the cluster gears, and the cap nut drives a slider to carry out reciprocating, and top and bottom impacts, to implement forging and punching. The entire device is controlled by an electric-pneumatic system. The swing cylinders comprise a cylinder body, a cylinder cap, a fixing block, a swing block, a swing shaft and an air nozzle. Braking is implemented by a pneumatic piston cylinder. The fly press of the utility model has the advantages of high transmission efficiency, simple structure, convenient operating maintenance and multiple strokes. Energy saving of the fly press reaches to 40-60%. The fly press can be widely applied to processes such as forge hot, cold forging, punching, stretch, etc., which are all processed by mechanical pressure.
Description
The utility model relates to fly press, the fly press in the technologies such as the forge hot that is used for mechanical pressure processing of more clearly saying so, cold forging, punching press, stretching.
The fly press in past can be divided into three types from transferring structure.First kind is friction screw press, and it is simple in structure, easy to operate, but transmission efficiency is low, has only about 20～28%, and speed is also slow, particularly can not satisfy the finish forge requirement of large forgings.Another kind is a hydraulic screw press, and transmission efficiency does not have fixing bottom dead centre about 33%, regulates easily, allow to produce the maximum cold that doubles nominal pressure and hit power, but complex structure, maintenance difficult, Hydraulic Elements are also fragile.The third is an electric screw press, and its transmission efficiency is 33%, and strokes per minute about 40 times is simple in structure, and braking is easy, and driving-chain is short, and impact energy is easy to adjust.But its motor commutates because of frequent at work, temperature rise, and power attenuation is big, impacts also very big to electrical network.Simultaneously, screw rod bears torsion on same cross section bigger, to large-tonnage development difficulty.
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of higher transmission efficiency that has is provided, and electrical network is not had impact substantially, energy-conservation, structure is simpler again simultaneously, and maintenance is easier to, and tonnage is also bigger, precision is higher, and the number of strokes is more, and bottom dead centre is fly press accurately.
In order to achieve the above object, the utility model fly press by base, be installed in workbench on the base, be installed in kinematic system on the base, be installed in the brakes of on the base kinematic system being braked, be installed on the base electric-pneumatic system that kinematic system and brakes are controlled and constituted.Base is last open type as friction screw press, and its crossbeam is formed one by two turnbuckles.Have T type groove on the workbench, can fastening mould.Kinematic system by two oscillating cylinders, with coaxial two pinions of the balance staff of oscillating cylinder, with the gear wheel of pinion, be installed in screw rod on the gear wheel, be installed in flywheel on the screw rod, formed with screw rod nut engaged and the slide block that is fastened on the nut.Oscillating cylinder by cylinder body and cylinder cap and valve, be installed in fixed block in the cylinder body and centering block, the balance staff that drives with fixed block and centering block and the encapsulant that is used for the cylinder body sealing formed.In other words, assemble on the balance staff of oscillating cylinder, fixed block, centering block, pinion are installed, assemble, be installed with gear wheel, flywheel, nut, slide block on the screw rod.Under compressed-air actuated promotion, balance staff is given pinion with transmission of power, and pinion is given gear wheel, screw rod, nut and slide block with transmission of power.So the slide block just guide rail on the base up and down reciprocatingly impacts.Flywheel is to rely on inertia to store momentum, as other friction press, relies on friction simultaneously again it is braked.
Brakes is made up of two air rammer cylinders and the brake shoes on the axis of the piston end face that is installed in piston cylinder.The axis of the piston promotes with compressed air, brake shoes and flywheel outer rim radial symmetric, and its friction catch mode is as friction screw press.The encapsulant of oscillating cylinder is a polytetrafluoroethylene (PTFE), and its sealing property has bigger improvement than other material.
This fly press is controlled with electric-pneumatic circuit, belongs to common electric-pneumatic circuit, has used maturation in fly press in the past and other lathe.Task of the present utility model comes to this and finishes.
The utility model fly press transmission efficiency height and fly press in the past compare, and transmission efficiency has improved 60～150%, thereby has received energy-saving effect preferably, can save energy 40～60%.Simultaneously, the utility model number of strokes can reach 56～65 times/minute, has improved than past 5～20 times/minute, thereby can raise labour productivity 10～50%.The utility model is simple in structure, operating maintenance is convenient, and is little to the impact of electrical network, can be widely used in the operations such as forge hot, cold forging, punching press, stretching in the mechanical pressure processing.
Below in conjunction with drawings and Examples the utility model fly press is done further explanation.Fig. 1 is the outline drawing of the utility model embodiment.Base 1, workbench 2, kinematic system 3, electric-pneumatic system 4 and brakes have been formed the utility model fly press among the figure.Fig. 2 is the schematic diagram of the kinematic system of the utility model embodiment.Among the figure, two oscillating cylinders 5, two pinions 6, gear wheel 7, screw rod 8, flywheel 9, nut 10 and slide blocks 11 have constituted kinematic system, and flywheel 9, gear wheel 7 and nut 10 are coaxial.Also illustrated the brakes formed by two air rammer cylinders 12 and brake shoes 13 among the figure.Just can brake when brake shoes 13 rubs with flywheel 9, its power is from electric-pneumatic system.Fig. 3 is the structural representation of oscillating cylinder 5.Cylinder body 14, cylinder cap 15, fixed block 16, centering block 17, balance staff 18, PTFE stuffing materials 19 are formed oscillating cylinder among the figure.During balance staff 18 rotations, just give pinion 6 with transmission of power.Fig. 4 is the profile of Fig. 3, can find out the relative installation of fixed block 16, centering block 17, cylinder body 14 and valve 20 among the figure, and power is then from compressed air.
The transmission efficiency of present embodiment is 0.85, improves 140% more in the past, and is energy-conservation 60%, and the number of strokes is 65 times/minute, and labor productivity has improved 48%.Use present embodiment operation, easy to maintenance, tonnage reaches 160 tons, can be used in forge hot, cold forging, punching press and the stretch process operation.
