Abstract
The utility model discloses an oil cylinder for a blending machine in the blending machine field. The oil cylinder comprises a cylinder body and a piston; the piston is matched with and arranged inside the cylinder body; the lower end of a piston rod of the piston extends out of the cylinder body from the lower end of the cylinder body; an opening of the lower end of the cylinder body is provided with a guide sleeve for sealing the cylinder body; the upper end of the cylinder body is provided with a worm gear and worm transmission pair; the center of the worm gear and the lower end of an adjusting screw rod are in threaded connection; a mechanical chock block is fixedly connected with the adjusting screw rod; and a limiting block is arranged on the shell of the worm gear and worm transmission pair. In operation, the upper end of the adjusting screw rod is relatively fixed with a stander; the lower end of the piston rod is connected with a slide block of the bending machine; and the journey of the bending machine can be driven through the adjusting screw rod to move up and down by the worm of the worm wheel in order that the cylinder body moves the position up and down to realize the position change of the slide block. The oil cylinder has a simple structure, easy manufacturing and reliable use as the size of the mechanical chock block can be not limited by the size of the piston rod; and the oil cylinder can be reliably applied to the bending machine.
Description
Technical field
The utility model relates to a kind of bender, particularly the oil cylinder of bender.
Background technique
The bender oil cylinder is one of important composition part of bender, existing bender oil cylinder, mainly by cylinder body, piston, adjust screw rod, electromechanical stop, guide sleeve, compositions such as worm and gear transmission, described worm and gear transmission is arranged on the cylinder body upper end, described worm gear is fixedlyed connected with adjustment screw rod upper end, the piston that piston rod is installed is equipped with in the cylinder body, described piston rod hollow, adjusting screw rod stretches in the piston rod, electromechanical stop is threaded in adjusts the screw rod lower end, be provided with feather key between electromechanical stop and the piston rod, the inboard of described piston rod hollow space is axially arranged with featherway, when adjusting the screw rod rotation, electromechanical stop can slide up and down along featherway, the inner bottom part of piston rod hollow space is provided with a limited step, limited step is corresponding with electromechanical stop, when electromechanical stop moves to conflict on limited step the time, electromechanical stop can not continue downward movement, but the stroke of limited piston, described guide sleeve sealing is arranged on cylinder body lower ending opening place, guide sleeve is inboard to be cooperated with rod seal, plays sealed cylinder block.This device in use, cylinder body is fixed on the frame, piston-rod lower end and bender slide block link, the active force that the oil cylinder epicoele produces during work is added on the slide block promotion slide block and does the work of plate bending and forming; The size of the size of stroke, bending workpieces angle, be to slow down by worm and gear by the fine setting motor, realize the position of the electromechanical stop on the adjusting adjustment screw rod, its complex structure, the size of piston rod, form and position tolerance required precision are higher, and manufacture difficulty is big, adjust screw rod and electromechanical stop also because of the restriction of piston rod size, rigidity is relatively poor, also owing to the working force of bearing long 1/2 bender tonnage, adjusts screw rod and electromechanical stop and also can cause screw thread plucking stuck phenomenon.
The model utility content
The purpose of this utility model provides a kind of bender oil cylinder, makes it simple in structure, and is easy to manufacture, moves more reliable.
The purpose of this utility model is achieved in that a kind of bender oil cylinder, comprise cylinder body and piston, described piston is equipped with in cylinder body, the piston-rod lower end of piston stretches out outside the cylinder body from the cylinder body lower end, cylinder body lower ending opening place is provided with the guide sleeve of sealed cylinder block, and the cylinder body upper end is provided with the worm and gear transmission, and described worm gear center and is adjusted the screw rod lower end and is threaded, adjust on the screw rod and be fixedly connected with electromechanical stop, the shell of worm and gear transmission is provided with limiting stopper.
The utility model when work, adjust screw rod upper end and frame relative fixed, piston-rod lower end and bender slide block link, and the active force that the oil cylinder epicoele produces during work is added on the slide block promotion slide block and does the work of plate bending and forming; The size of the size of stroke, bending workpieces angle can be by the input of the worm screw in the worm and gear transmission, and worm gear drives is adjusted screw rod and moved up and down, and makes cylinder body move up and down the position, to realize the change of slide position; Compared with prior art, the utility model is simple in structure, easy to manufacture, can not cause screw thread plucking stuck phenomenon, the size of electromechanical stop can not be subjected to the restriction of piston rod size, so electromechanical stop can be sufficiently large, can have bigger rigidity, use more reliably, the utility model can reliably be applied on the bender.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 positive stop, 2 adjust screw rod, 3 limiting stoppers, 4 worm gears, 5 worm screws, 6 pistons, 7 piston rods, 8 cylinder bodies, 9 guide sleeves.
Embodiment
As figure, be the bender oil cylinder, comprise cylinder body 8 and piston 6, described piston 6 is equipped with in cylinder body 8, stretch out outside the cylinder body from cylinder body 8 lower ends piston rod 7 lower ends of piston 6, cylinder body 8 lower ending opening places are provided with the guide sleeve 9 of sealed cylinder block, cylinder body 8 upper ends are provided with the worm and gear transmission, the worm and gear transmission is made up of worm gear 4 and worm screw 5 and corresponding shell, described worm gear 4 centers and one are adjusted screw rod 2 lower ends and are threaded, adjust on the screw rod 2 and be fixedly connected with electromechanical stop 1, the shell of worm and gear transmission is provided with limiting stopper 3, the worm gear loam cake that this limiting stopper 3 can be the worm and gear transmission.
During work, adjust screw rod 2 upper ends and frame relative fixed, piston rod 7 lower ends and bender slide block link, and the active force of oil cylinder epicoele generation is added on the slide block promotion slide block and does the work of plate bending and forming during work; The size of the size of stroke, bending workpieces angle can be by 5 inputs of the worm screw in the worm and gear transmission, and worm gear 4 drives adjustment screw rod 2 and moves up and down, and makes cylinder body 8 move up and down the position, to realize the change of slide position; It is simple in structure, and is easy to manufacture, can reliably be applied on the bender.
