Full-automatic feeding device of punching machine

Abstract

The invention belongs to the technical field of punching machines, and relates to a full-automatic feeding device of a punching machine. The full-automatic feeding device comprises a loading table and a feeding mechanism, wherein the loading table and the feeding mechanism are controlled by a controller to act. The loading table is specifically and structurally characterized in that a rotary table is fixed on a rotating shaft which is driven by a power unit and arranged on a rack; more than two positioning groove sets are evenly distributed in the same circles in the rotary table, wherein the radii of the circles are the same, and the circles are drawn around the same center; each positioning groove set is formed by two arc grooves which are arranged in a spaced mode; a positioning rod is arranged in each arc groove; a positioning rod positioning device is arranged on the lower side of the rotary table; a material position is formed between the two positioning rods of each arc groove set; a hole or groove used for an ejector bar to penetrate through is formed in each material position; the ejector bar driven by the power unit to act is arranged on the lower side of the hole or groove. The full-automatic feeding device of the punching machine has the advantages that materials are convenient to pile, take and feed, the degree of automation is high, and the full-automatic feeding device is applicable to the punching machine.

Description

Technical field [0001] The invention belongs to the technical field of punching machines, and specifically refers to a fully automatic feeding device of a punching machine. Background technique [0002] At present, the operation of stamping and drawing processes is mainly operated manually. A small number of enterprises have begun to use automatic feeding devices. Its shortcomings are used in: First, the technical level is not high: because the automatic feeding of stamping equipment is still in the early stage of application, it is popular The rate is low, and the degree of automation and intelligence of automatic feeding needs to be improved; second, it takes a long time to adjust the refueling device: the existing refueling adjustment basically uses manual adjustment of the positioning rods and positioning blocks, because manual adjustment requires skilled technology Workers have repeatedly adjusted, resulting in a larger proportion of the refueling adjustment time in the tota...

Problems solved by technology

[0002] At present, the operations of stamping and stretching processes are mainly operated manually, and a small number of enterprises have begun to use automatic feeding devices. The rate is low, and the degree of automation and intelligence of automatic feeding needs to be improved; the second is that it takes a long time to adjust the refueling device: the existing refueling adjustment basically uses manual adjustment of the position of each positioning rod and positioning block, because manual adjustment requires skilled technology Workers make multiple adjustments, causing the time for refueling adjustment to account for a large proportion of the total production time. For small batch products, some refueling adjustment time exceeds the production time; the third is the slow feeding speed: for high-speed stamping equipment such as punching machines, The feeding working time of automatic feeding has a great influence on the production efficiency, so a higher-speed feeding device is needed to improve the production efficiency. In addition, the blowing and splitting device of the blank in the prior art is mainly composed of a large-caliber device with a fixed position and a long distance. Air nozzles or porous air nozzles are used to separate overlapping sheets. Because this method does not blow air at close distances to the edges of the sheets, most of the conveyed sheets are overlapping sheets. The stamping equipment punches overlapping sheets. It will cause adverse consequences such as shutdown of automatic feeding equipment and stamping equipment, damage to molds, etc.
