Abstract

The utility model discloses a kind of central siphon mouth closing devices.It includes die sleeve and the mouth closing-in mould and deforming moulds that can be sequentially arranged in die sleeve, deforming moulds, which have, can make central siphon squeeze the cone-shaped cavity to form required form, mouth closing-in mould recycles the barrier effect of closing-in mould to control the length of central siphon mouth and end form with the closing in chamber controlled after making central siphon form required state central siphon mouth length and form, central siphon after the extruding by deforming moulds.After above-mentioned structure, utilize the positional relationship of deforming moulds and mouth closing-in mould, central siphon extrusion forming will first be thickened, the closing in effect of mouth closing-in mould is recycled to control mouth length and mouth end flatness, to which the central siphon thickness and mouth that reach required in technique are long, ingenious ground structure design not only ensure that gage variation, and production efficiency is improved, more accomplish consistency and stability when batch production.

Description

Central siphon mouth closing device

Technical field

The utility model relates to a kind of central siphon auxiliary machining device, specifically a kind of central siphon mouth closing device.

Background technique

After the axle completion of integral type semitrailer thickens, extruding is carried out by process and drawing requirement and forms final product, Traditionally the extruding of axle is generally and passes through extrusion die directly to squeeze, due to being squeezed and deformed so that mouth is very long after formed product And out-of-flatness, cause extrusion position gage variation larger, need not stop to detect, entire production process consuming working hour is long, production Inefficient, product qualification rate is unstable, high production cost.

Summary of the invention

The technical problem to be solved by the present invention is to provide it is a kind of can length to mouth and form control it is same When guarantee gage variation, improve the central siphon mouth closing device of production efficiency.

In order to solve the above-mentioned technical problem, the central siphon mouth closing device of the utility model, including die sleeve and can be according to The secondary mouth closing-in mould and deforming moulds being mounted in die sleeve, deforming moulds, which have, can make central siphon squeeze to form required form Cone-shaped cavity, mouth closing-in mould have so that central siphon is formed required state after central siphon mouth length and form controlled Closing in chamber, central siphon recycle the barrier effect of closing-in mould to make length and the end of central siphon mouth after the extruding by deforming moulds Portion's form is controlled.

The closing in chamber includes the tapered surface of one end cylindrical hole and the setting of cylindricality outer end of hole, and the closing in chamber can be to axis The length in ozzle portion controls and passing through the limit of tapered surface keeps end smooth.

The spacer positioned at mouth closing-in mould anterior end is additionally provided in the die sleeve.

After above-mentioned structure, due to setting can the die sleeve deforming moulds and mouth closing-in mould successively installed, Using the positional relationship of deforming moulds and mouth closing-in mould, central siphon extrusion forming will be first thickened, recycles mouth closing-in mould Closing in effect it is mouth is long and mouth end flatness controls, so that it is long to reach required in technique central siphon thickness and mouth, Ingenious ground structure design, not only ensure that gage variation, and improve production efficiency, has more accomplished one when batch production Cause property and stability.

Detailed description of the invention

Fig. 1 is the schematic diagram of the section structure of the utility model central siphon mouth closing device.

Specific embodiment

With reference to the accompanying drawings and detailed description, the central siphon mouth closing device of the utility model is made further detailed Explanation.

As shown, the central siphon mouth closing device of the utility model, including die sleeve 1 and die sleeve can be sequentially arranged at Interior mouth closing-in mould 2 and deforming moulds 3, deforming moulds 3, which have, can make central siphon squeeze the conical cavity to form required form Body 4, mouth closing-in mould 2 is with the closing in chamber controlled after making central siphon form required state central siphon mouth length and form 5, central siphon recycles the barrier effect of closing-in mould 2 to make length and the end of central siphon mouth after the extruding by deforming moulds 3 Form is controlled.

Further, described closing in chamber 5 includes the tapered surface 7 that one end cylindrical hole 6 and cylindricality outer end of hole are arranged, and is closed up Chamber 5 can control the length of central siphon mouth and passing through the limit of tapered surface keeps end smooth, by the technical solution, utilize column Shape hole controls the length of central siphon mouth, keeps end smooth by the limit of tapered surface, is additionally provided with and is located in die sleeve 1 The spacer 8 of mouth closing-in mould anterior end further ensures product quality by the isolation of spacer.

In use, mouth closing-in mould is first put into die sleeve, then deforming moulds are put into；In this way, being formed according to central siphon The positional relationship of mold and central siphon mouth closing-in mould makes central siphon when heating extruding, accomplishes first to form, and mouth is recycled to close up The barrier effect of mold, guarantee metal toward requiring position to flow and accumulation, meanwhile, using the barrier effect of mouth closing-in mould, The length of central siphon mouth is controlled, and ensure that end is smooth, to accomplish consistency when batch production, stability.
