Description

The punching press pay-off

The utility model relates to a kind of pay-off from stamping parts to punch press that send into.

Carrying out stamping parts with punch press, all is at present the mode that adopts artificial feeding, and not only labour intensity is big, and is absolutely unsafe, and production efficiency is low, also is unfavorable for saving material.

The purpose of this utility model provides a kind of punching press pay-off, and it is artificial to adopt mechanical system to replace, and reduces labor intensity, and improves security, enhances productivity.

Punching press pay-off of the present utility model comprises frame, it is characterized in that frame is provided with track, and slide plate is arranged on the track, and the bottom of slide plate has teeth groove, teeth groove and transmission device engagement, and transmission device is fixed on a connection piece, is fixed with the feeding element on the slide plate.

Described feeding element comprises and being fixed on the slide plate and vertical with it lower platen, a corresponding top board above the lower platen, the top board end passes slide plate, lowermost end is equipped with bearing, the compression spring is installed in top board and is connected with bearing, and a plane is arranged below track on the frame, two set square spares at interval are set on the plane, the bearing of top board bottom and plane contact, two set square spares are distinguished corresponding material loading and discharge position on the orbit of top board bearing.

Described transmission device comprises power transmission shaft, and the power transmission shaft two ends are gear, outer end gear and tooth bar engagement, and tooth bar and connector are fixed.

The supporting use of the utility model and punching apparatus, fixedly connected with the drift of punch press by connector, moving up and down of drift drives the positive and negative rotation of transmission device, thereby the drive slide plate advances or retreats, the part that is stamped at one end is positioned on the feeding element, unload from the feeding element in the mold cavity that enters punch press at the other end, the feeding process does not need manually.Concrete a kind of mode is: top board and lower platen advance simultaneously with slide plate or retreat, bearing runs on the inclined-plane of triangle plate, top board by the compression spring effect by jack-up, during by jack-up, in opened condition, the part that is stamped can be placed on the lower platen or from lower platen and unload between top board and lower platen; Bearing leaves the triangle plate, and the top board effect of spring by compression falls after rise, is closure state between top board and lower platen, and the part that is stamped therebetween is clamped.Initial state, drift are in the state (mentioning) that will upwards move, and top board and lower platen in opened condition, are put the part that is stamped under the effect of triangle plate.When drift moved upward, transmission device drove slide plate and advances along track, and the bearing of top board leaves the triangle plate simultaneously, and the compression spring falls top board after rise, clamps the part that is stamped, and is the feeding state; When reaching second triangle plate place, drift is up to assigned position, the bearing of top board bottom is on the inclined-plane of triangle plate simultaneously, the compression spring is squeezed, and makes top board by jack-up, unloads the part that is stamped, enter in the punching machine mold chamber, during the downward punching press of drift, drive transmission device, slide plate retreats along track, reaches the home position.Operation so repeatedly realizes being stamped part feeding process.

Slide plate and interorbital can also can be the modes (as the bearing way of contact) of rolling friction as the mode of common sliding friction.Same top board passes the way of contact between slide plate and slide plate, promptly can be the sliding friction mode, also can be to realize the stroke that rolls by adding modes such as bearing.

Below in conjunction with the embodiment description of drawings:

Fig. 1 is a structural representation of the present utility model;

Among the figure: 1 frame, 2 connectors, 3 tooth bars, 4 external gears, 5 power transmission shafts, 6 internal gears, 7 teeth groove, 8 slide plates, 9 lower platens, 10 top boards, 11 compression springs, 12 bearings, 13 triangle plates, 14 tracks, 15 planes

Track 14 is set on the frame 1, and slide plate 8 slides along track 14.Power transmission shaft 5 is installed on frame, and the two ends of power transmission shaft are gear, external gear 4 and internal gear 6.External gear 4 and tooth bar 3 engagements, tooth bar 3 is fixing with connector 2, and connector 2 is fixedlyed connected with the drift of punch press, and link position is not as long as hinder drift work all can.The bottom of slide plate 8 has teeth groove 7, teeth groove 7 and internal gear 6 engagements.Fixedly lower platen 9 is vertical with it on the slide plate, and correspondence is installed pressing plate 10 on the lower platen, and the top board end passes the slide plate plane, and lowermost end has bearing 12, and top board 10 interior installations are compressed springs 11 and are connected with bearing.One plane 15 is arranged below track on frame 1, and bearing 12 and plane contact are provided with two set square spares 13 on the plane 15.As shown in the figure, at lower platen 9, top board 10 is positioned at triangle plate 13 places on the right, the drift of punch press is in the state that will upwards move, bearing 12 is on the inclined-plane of triangle plate, extruding compression spring 11, thereby make top board 10 by jack-up, on, be in open mode between lower platen, part is stamped on placing betwixt, when drift upwards moves, drive tooth bar 3 motions by connector 2, rotate with the external gear 4 of tooth bar engagement, drive power transmission shaft 5, internal gear rotates, the teeth groove engagement of internal gear and slide plate, drive slide plate 8 (left among the figure) slip forward, lower platen, top board moves forward thereupon, and bearing 12 leaves the inclined-plane of triangle plate, rolls in the plane, extruded compression spring 11 will make top board fall, the clamping part that is stamped, when triangle plate 13 places that run to the left side, drift has been up to assigned position, the just in time mold cavity position of corresponding punch press of part is stamped, bearing makes the compression spring be squeezed the jack-up top board again on the inclined-plane of this triangle plate, the part that is stamped is entered in the mold cavity of punch press, drift downwards towards the time, the rotation direction of power transmission shaft is opposite with original direction, drives slide plate and draws back, simultaneously, bearing leaves the inclined-plane of triangle plate again, moves backward along original plane, returns the origin-location, repeat said process, finish the mechanical transport process of the part that is stamped.

Advantage of the present utility model:

Use mechanical system, replace manually finishing the self-feeding of stamping parts. Simple in structure, reliable, alleviate Labour intensity, greatly improved production efficiency, avoided the danger of artificial feeding, can use to greatest extent Raw material, thus raw material saved.
