Abstract

The invention discloses a small shaft cold extrusion self-ejection system device, which comprises a pedestal, a spring pedestal, a spring, a slide block, a slide block cylinder body, a baffle plate, a mould, an ejector rod, a cylinder mould, a mould sleeve and a pressing rod, wherein the spring pedestal is arranged on the pedestal; the spring is arranged on the pedestal; the slide block is arranged on the spring; the slide block cylinder body is connected with the slide block; the baffle plate is connected with the slide block cylinder body; the mould is arranged on the baffle plate; the ejector rod is arranged in the mould; the cylinder mould is arranged on the mould; the mould sleeve is connected with the baffle plate and is positioned together with the mould and the cylinder mould through thread matching; and the lower end of the pressing rod is arranged on the slide block, and the upper end of the pressing rod is connected with a mould seat on a press. According to the small shaft cold extrusion self-ejection system device, elastic performance of the nitrogen spring stored in the self-ejection system can be released during return travel of the press after a workpiece is formed, so that the workpiece is automatically ejected out, the press is not required to be operated by a worker to eject the pressing rod out each time, the original production flow is greatly improved, automatic production is realized, and the production efficiency is increased.

Description

The cold extrusion of a kind of little axle is from the ejection system device
Technical field
The present invention relates to a kind of cold extrusion system and device, relate in particular to the cold extrusion of a kind of little axle from the ejection system device.
Background technology
In the spline forming process of little axial workpiece, plastic force is often less, and ejecting force is also less; In traditional extrusion molding, the operator often wants operating pressure machine button, makes push rod upwards eject formation of parts; This method inefficiency, labor strength is high.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, the little axle cold extrusion that a kind of mechanical automation is provided is from the ejection system device.
In order to realize above purpose, a kind of little axle of the present invention cold extrusion is from the ejection system device,
Comprise base, spring pedestal, spring, slide block cylinder body, slide block, baffle plate, push rod, mould, depression bar, die sleeve and barrel mould; Wherein, spring pedestal is positioned on the base, and spring is positioned on the spring pedestal, and slide block is located on the spring, and slide block cylinder body upper end links to each other with slide block, and the lower end is fixedly connected with base; Baffle plate links to each other with the slide block cylinder body, is connected with die sleeve simultaneously; Mould is located on the baffle plate, is provided with described push rod in this mould, and the barrel mould is located on the mould, and die sleeve through threaded engagement and charging basket mould, mold position together; The depression bar lower end is located on the slide block, and the upper end links to each other with the forcing press upper bolster.
Wherein, as preferably, mould is the profile of tooth mould.
Beneficial effect: little axle provided by the invention cold extrusion is from the ejection system device, behind component shaping, when the forcing press backhaul; Be stored in that the elastic energy of nitrogen spring discharges in ejection system; Make workpiece eject automatically, workman's operating pressure machine at every turn makes push rod eject, and has improved original production procedure greatly; Realize automated production, improved production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention.
As shown in Figure 1, little axle of the present invention cold extrusion comprises base 1 from the ejection system device, establishes
Spring pedestal 2 on this base 1 is located at the spring 3 on this spring pedestal 2, is located at the slide block 5 on this spring 3; The upper end links to each other the slide block cylinder body 4 that the lower end is fixedly connected with base 1, the baffle plate 6 that links to each other with this slide block cylinder body 4 with this slide block 5; Be located at the profile of tooth mould 8 on this baffle plate 6, be located at the push rod 7 in this profile of tooth mould 8, be located at the barrel mould 11 on this profile of tooth mould 8; The die sleeve 10 that links to each other with said baffle plate 6; This die sleeve 10 is positioned at profile of tooth mould 8, charging basket mould 11 through threaded engagement, comprises that also the lower end is located on the slide block 5 depression bar 9 that the upper end links to each other with the forcing press upper bolster.
The present invention accomplishes the shaping starting stage of the spline workpiece of little axial workpiece earlier before use, and workpiece is placed on the profile of tooth mould 8, when forcing press moves downward; Force workpiece to move downward generation crimp, simultaneously, push rod 7 moves downward through slide block 5 stressed on spring 3; After the shaping of workpiece parts of tooth finished, spring 3 had stored corresponding elastic energy, when the forcing press backhaul; The energy that is stored in the spring discharges, and ejects workpiece through push rod 7, and whole forming process is accomplished.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
