Abstract

The utility model discloses a precision gear automatic feeding device arranged on a high-speed punch press. The precision gear automatic feeding device structurally comprises a one-way device, rollers, a disc brake, an eccentric disk and a pull rod, wherein the one-way device consists of the eccentric disk, the pull rod and a rocker arm; the eccentric disk is fixed on a punch press main shaft; the eccentric disk is used for driving the pull rod in the vertical stroke of the punch press; the pull rod is connected with the rocker arm; the rocker arm is used for driving the rollers to realize one-way feeding; the upper end of the pull rod is movably connected with the eccentric disk, and the lower end of the pull rod is connected with the rocker arm, a rocker arm shaft and the rollers; the disc brake is arranged on one side of the working face of a punch press base, and consists of a releasing shaft, a releasing handle, a fixing hole, a releasing bracket and a compression spring; two faces of a brake lining are fully contacted through a clutch; a reversion device comprises a graduation ring on the eccentric disk for realizing accurate adjustment of the distance and angle of the pull rod, so that slight reversion of the rocker arm and the rollers is prevented, and an accurate feeding step pitch is realized. The precision gear automatic feeding device has the advantages of simple structure, convenience in operation and long service life; the electric power is saved, the production efficiency is increased by one time, and the machining accuracy is increased.

Description

Be located at the precision gear automatic feeding on high velocity ram machine

Technical field

The utility model relates to mechanical transmissioning technology field, relates in particular to the precision gear automatic feeding on high velocity ram machine, replaces existing pneumatic discharge apparatus.

Background technology

The pneumatic discharge apparatus using on existing punch press, source of the gas adopts air compressor, driving the power supply of compressor is 240V voltage by 380V voltage transition, compressed air enter magnetic valve commutate action one control advance, retreat, carry out feeding punching, shortcoming is that the fluctuation because of bleed pressure and supply voltage affects pushing precision, general feeding step pitch accuracy 0.03～0.05mm, feeding effect is low, 40～50 beats/min per minute, in order to overcome above-mentioned technical and defect, ad hoc this precision gear automatic feeding of having counted.

Utility model content

The purpose of this utility model be to provide the precision gear automatic feeding of a kind of use on high velocity ram machine, its structure mainly comprises non-return device, roller, butterfly brake, eccentric disc, pull bar; Non-return device is comprised of eccentric disc, pull bar, rocking arm, eccentric disc is fixed on punch press main shaft, during the upper and lower stroke of punch press, by eccentric disc, drive pull bar, pull bar is connected with rocking arm; rocking arm drives roller to realize unidirectional feeding; pull bar upper end is flexibly connected with eccentric disc; lower end is connected with rocking arm, rocker arm shaft and roller; butterfly brake is located at punch press support working face one side; mainly by loosening axle, loosen handle, fixing hole, loosen support, binder spring forms, with senior clutch lining two sides, entirely contact; Reverse device comprises the angle that calibration loop on eccentric disc and chute are realized fine adjustment tie bar space, makes rocking arm, roller not produce trickle falling back, and realizes feeding step pitch accurate.

Adopt the beneficial effect of the technical program: simple in structure, easy to operate, long service life, can continuous operation more than 5 years, multiple-project is processed continuously, replace pneumatic discharge apparatus, save power supply and than originally, improved production efficiency, one times of left and right, machining accuracy improves greatly.

Accompanying drawing explanation

Fig. 1 is that pay-off described in the utility model is arranged on the structural representation on punch press;

In figure: 1-non-return device, 2-roller, 3-butterfly brake, 4-eccentric disc, 5-pull bar.

The specific embodiment

The precision gear automatic feeding being located on high velocity ram machine described in the utility model, its specific embodiment, now contrasting accompanying drawing elaborates: this device is arranged on the left side of high velocity ram machine or the right axle that is in transmission connection (pull bar) by an adjustable size precision eccentric scale adjustment disk (abbreviation eccentric disc) is fixed on the main shaft of high velocity ram machine, the punch press feed appliance that stroke drives drive link (pull bar) drive link to make to be arranged on punch press by the eccentric disc on main shaft each time returns multiple operation, punch press makes to be arranged on eccentric disc on punch press main shaft by peak (top dead-centre) running and drives pull bar to make to be connected to gear main shaft on dwang and feed appliance to counterclockwise motion by pull bar operation downwards, completing to set needs length of material to press from both sides material requested by roller manipulator, punch press is made to be arranged on eccentric disc on punch press main shaft and drives gear main shaft on pull bar and feed appliance to moving clockwise when peak moves by minimum point, to the direction of punch press, move and complete the length of material setting, by roller manipulator, carry out the program of material folding feeding, back and forth complete the process of feeding punching material folding.

The formation of critical piece comprises: non-return device 1, roller 2, butterfly brake 3, eccentric disc 4, pull bar 5; Non-return device is comprised of eccentric disc 4, pull bar 5, rocking arm, eccentric disc 4 is fixed on punch press main shaft, during the upper and lower stroke of punch press, by eccentric disc, drive pull bar, pull bar is connected with rocking arm; rocking arm drives roller 2 to realize unidirectional feeding; the upper end of pull bar is flexibly connected with eccentric disc; lower end and rocking arm; rocker arm shaft and roller are connected; roller 2 is a pair roller, and roller two ends are provided with gear intermeshing, bottom roller gear and the engagement of rocker arm shaft gear; rocker arm shaft is connected with rocking arm, and rocking arm is connected with the lower end of pull bar 5.Butterfly brake 3 is located at punch press support working face below one side, mainly by loosening axle, loosen handle, fixing hole, release handle, loosen support, binder spring forms, with senior clutch lining two sides, entirely contact.Reverse device comprises the angle that calibration loop on eccentric disc 4 and chute are realized fine adjustment pull bar 5 distances, and rocking arm, roller can not produce trickle setback, and it is accurate to realize feeding step pitch.
