Abstract

The utility model relates to a precision feeder, which is a feeder device for a high precision metal net cover matched and processed with a punch press to form a proper shape. The utility model is composed of machine frames, a lower roller, an upper roller, a regular ratchet wheel, a swing rod, and a reversal ratchet wheel. The main shaft of a punching machine causes the swing rod to periodically swing via a shaft of a rod end and a bearing, and the main shaft of the punching machine causes the upper roller and the lower roller to simultaneously rotate in opposite direction via the regular ratchet wheel and a gearwheel on the shaft end. A metallic belt clamped between the upper roller and the lower roller is transferred to the punching machine step by step to form the proper shape by punching. The stepping length of belt material can be accurately controlled via the stepped toothed number of the regular ratchet wheel. A one-way bearing and the reversal ratchet wheel can effectively avoid the reverse rotation of the rolling wheel. The utility model has the advantages of artful structure, stable running, and precise feeding length.

Description

The inching device

The utility model relates to a kind of special-purpose feeder equipment that utilizes punch press machine-shaping metal guard.

The metal guard of certain electrophonic musical instrument utilizes punch press dotting punch and moulding, its raw material is the disk type metal band of 0.7 * 191mm, every dribbling material weighs hundreds of kilograms, the mesh centre-to-centre spacing of guard is 2.2 ± 0.01mm, so high mesh precision has proposed high requirement to the feeding of punch press, does not still have in the prior art and to reach the feeder equipment of high precision like this with the supporting use of punch press.

The purpose of this utility model promptly is to design a kind of and the matching used inching device of punch press, when utilizing the above-mentioned metal guard of punch press machine-shaping to satisfy to the requirement of guard mesh precision.

To achieve these goals, the utility model utilizes frame and bottom roller, upper roller, forward ratchet, fork and reverse ratchet to constitute a kind of inching device.The punch press main shaft makes fork make periodic wobble by rod end axle and bearing and makes upper and lower roller locking phase to rotation by forward ratchet and shaft end gear, and dotting punch and moulding in the punching machine mold are sent in the metal tape material stepping that will grip between upper and lower roller.

In the inching device of said structure,, can accurately control the stepping length of band material as long as suitably design the tooth number and the stepping tooth number of forward ratchet; Oppositely ratchet and single channel bearing then can effectively prevent the roller counter-rotating, guarantee to be with the precision of expecting stepping length.Therefore, when utilizing above-mentioned inching device and the supporting use machine-shaping of punch press metal guard, can fully satisfy requirement to metal guard mesh precision.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model inching device.

Accompanying drawing 1 is the structural representation of the utility model inching device.

With reference to the accompanying drawings 1, the utility model inching device is mainly by frame, bottom roller, upper roller, the forward ratchet, fork and reverse ratchet constitute, bottom roller 1 is cylindrical, be installed on the frame 5 and can be by wheel shaft 2 and needle bearing 3 and single channel bearing 4 levels around wheel shaft 2 one-directional rotation, the left end of wheel shaft 2 has and intermeshing bottom roller shaft end gear 6 of upper roller shaft end gear and the sprocket wheel 7 that is used for the transmission feed appliance, upper roller 8 also is cylindrical, its diameter equates with bottom roller, by wheel shaft 9, bearing 10 and sliding sleeve 11 levels are installed in the frame slotted eye of bottom roller 1 top, and can in the frame slotted eye, move up and down by the slip of sliding sleeve 11, the left end of its wheel shaft 9 have with the intermeshing upper roller shaft end gears 12 of bottom roller shaft gear 6 and can be by the shaft end gear transmission around wheel shaft 9 and bottom roller 1 locking phase to rotation.The top of sliding sleeve 11 has and sliding sleeve 11 can be pressed to the stage clip 13 of bottom roller 1 and adjusted screw 14 together with upper roller 8, also is equipped with on the sliding sleeve 11 by eccentric bushing 15, back-up block 16 and 17 mechanisms of arguing for the sake of arguing that form and be used for sliding sleeve 11 is lifted away from together with upper roller 8 bottom roller 1 of arguing for the sake of arguing.Forward ratchet 18 is fixed on the right-hand member of bottom roller axle 2 and can drives bottom roller 1 by wheel shaft 2 by flat key and rotates synchronously, and its left side has the adjustment cover 19 of coarse adjustment stepping tooth number (or step feeding length).Fork 20 is installed on the bottom roller axle 2 on forward ratchet 18 right sides and can be around wheel shaft 2 swing, its top has to work in coordination with forward ratchet 18 cogs and collapses pin 21 with the gram of stirring forward ratchet 18, its lower end links to each other with the punch press main shaft with bearing 23 by rod end axle 22, oppositely ratchet 24 is fixed on the bottom roller axle 2 on single channel bearing 4 right sides, its bottom side has the gram of working in coordination with it and collapses pin 25, to prevent that wheel shaft 2 from reversing because of the deadweight of disc type strip, its outside has the damping block 26 of working in coordination with it, so that the running held stationary of roller.

The feeding process of the inching device of said structure is as follows: when the every dotting punch of punch press one time, the eccentric bushing of its main-axis end promptly makes fork swing an angle by rod end bearing and rod end axle, when fork swung to the air-conditioning place that adjusts cover, the gram on fork top collapsed lock and promptly slides to the root of the tooth place of forward ratchet rapidly and drive forward ratchet rotating certain angle (being stepping tooth number) under the effect of spring.And then drive to go up the bottom roller locking phase to rotating certain angle, be clamped at band material between the bottom roller promptly to punch press stepping 2.2mm.

Structure of the present utility model is ingenious, operate steadily and feed length accurate, be a kind of high-accuracy feed appliance, thus be particularly suitable for as with the feeder equipment of the high-accuracy metal guard of punch press accessory processing moulding.
