Description

Multi-station feeding mechanism of plate hydraulic punching machine

Technical Field

The invention relates to the field of hydraulic punching machines, in particular to a feeding mechanism of a multi-station plate hydraulic punching machine.

Background

Hydraulic punching machines are a type of mechanical device for creating holes in metallic materials or cutting specific shapes, which use hydraulic systems to provide high pressure to push punches (or dies) through metallic sheets, and are commonly used in the metal working industry, particularly in the manufacturing field, for producing various metallic parts and components.

Hydraulic punches typically employ an automatic feed system during the sheet stamping process. The multi-station hydraulic punching machine can refer to a punching production line formed by a plurality of hydraulic punching machines, or a single hydraulic punching machine performs a punching process by using a plurality of punches. These processes require a continuous feeding structure, i.e. a plurality of gripping structures on the feeding device work simultaneously, and grip the workpiece in the previous process to the next process so as to orderly perform the feeding work.

In order to ensure that the feeding can be performed orderly one by one, the factory uses a mechanical part Zhang Qijin to separate the two plates by lifting them against the edges of the plates, however, some metal plates are at risk of corrosion during production, transportation and storage, and therefore may be coated with an anti-corrosion oil film during manufacture, which helps to protect the metal surfaces from oxidation, corrosion and rust. Therefore, the surfaces of the plates are often affected by factors such as an oil film, sheets are easy to adhere together, double adhesion or multiple adhesion is caused, meanwhile, the plates are not orderly stacked in the transportation and production processes, and the two plates can be lifted together when the mechanical separator is used for separating, so that the plates cannot be separated. When the punch is pressed down, the die may be cracked, the product is damaged, and for a multi-station hydraulic punch, the whole production line can stop running once an abnormal condition occurs at one position of the feeding mechanism. To avoid this, manufacturers typically use sensors to detect the sheet. Once the double-material condition is found, the feeding mechanism stops running and is required to separate the double-sticky or multi-sticky plates in a manual or mechanical arm mode, and the two modes are stopped when running, so that the double-sticky plates can be normally operated after being separated or taken down, and the working efficiency of the feeding mechanism is greatly influenced.

Therefore, a multi-station feeding mechanism of a plate hydraulic punching machine is provided.

When using thin iron sheet to carry out punching press production, because thin iron sheet material has crooked characteristic, when two panels are about to separate to result in, the detection platform of below can be because the reason of gravity down move, and two panels still adhere together, lead to two panels to appear crooked, make the surface of two panels scratch, lead to panel surface to appear scraping, and make the sucking disc drive the top panel separation back through spacing, and remove the landing just can take place for a certain distance detection platform, the arc water conservancy diversion strip of limit strip bottom installation can reduce its area of contact with panel simultaneously, further avoid scraping, simultaneously because the panel that needs the second baffle to prevent the below slides, so once only panel takes place crooked, will lead to the second baffle to block the panel of below, improve the application scope of material loading equipment through spacing, and work efficiency of feed mechanism is improved.

The reset piece comprises a spring rod and a push plate, wherein the spring rod is fixedly installed in the placing groove, the push plate is fixedly installed at the movable end of the spring rod, a plurality of convex blocks which are uniformly arranged are fixedly installed in the placing groove, the convex blocks are arranged in an arc shape, and the convex blocks are all arranged on one side of the penetrating groove.

Because the below panel has got into the slope department of blowing groove before the separation, lead to the sucking disc of top unable quick suction to play the panel, so need make the panel shift out the slope department earlier, and can drive the panel of below and leave the slope department through sucking disc and the promotion piece of below, but because the sucking disc can lead to the relative position of other panels to change because of the oil film, lead to it unable accurate to push back the panel, so need the piece that resets, when the panel gets into the slope department, need promote the promotion piece and remove, and extrude the spring bar, and after sucking disc and below panel break away from, the spring bar that is compressed can promote the panel and get back to the normal position, make the sucking disc can drive the panel fast and carry out the material loading, improve equipment's production efficiency.

Meanwhile, an oil film is also arranged at the bottom of the plate. When the suction cup is placed in the discharge groove, the suction cup is attached to the discharge groove, so that the suction cup is increased in material taking difficulty, adsorption between the plate and the floor plane can be avoided through a plurality of uniformly arranged convex blocks, the fact that the compressed spring rod cannot push the plate below to move, the plate cannot return to the original position, and the production efficiency of equipment is affected is avoided.

Compared with the prior art, the invention has the beneficial effects that:

1. when the detection table detects that the double-sticky plates appear, the electromagnet at the lower part is electrified to generate magnetic force to enable the sucking disc at the lower part to rise so as to resist the plates at the lower part to adsorb, the sucking disc at the upper part also moves downwards to the detection table to adsorb the plates at the upper part due to material taking, the movable end of the first pneumatic telescopic rod contacts with the electromagnet shell through the pushing block to push the two plates at the upper part to move so that the two plates resist the inclined surfaces to stagger each other, the first baffle plate and the second baffle plate resist the two plates after staggering, the plates cannot displace in the separation process, the sucking disc at the upper part behind the plates drives the plates to move due to the long feeding arm, the two plates are completely separated, the plates are separated in the operation process of the feeding mechanism, and the working efficiency of the feeding mechanism is greatly improved.
