Abstract
The invention discloses a spinning sealing process method for a pipe port. The spinning sealing process method for the pipe port mainly comprises the following steps of clamping for fixing, heating the port, spinning, and sealing. A lathe is used for controlling a spinning wheel to carry out axial feeding; radial feeding is manually controlled; a pipe is subjected to necking spinning; the spinning wheel carries out reciprocating motion according to the specified shape; when spinning is carried out to later-stage closing, the concave edge surface of the spinning wheel extrudes the pipe; and meanwhile, the pipe closing position is applied with certain pressure in the axial direction to close the pipe. According to the invention, a simple process method is adopted to solve the spinning closing problem of the pipe, and the process method is especially suitable for the spinning closing of small-diameter 30CrMnSi and other black metal pipes, the pipe subjected to the spinning closing is evenly stressed, big feeding can be adopted for processing, and the production efficiency is high.
Description
Technical field
The present invention relates to material plastic forming manufacture field, relate in particular to a kind of technological method for processing of minor diameter tubing rotation press closing.
Background technology
In the leverage supporting construction, the supporting rod termination often need be sealed, it is lower that it seals required precision, usually, the pipe fitting enclosuring structure adopts two sections ways of connecting, and end socket adopts machining to be shaped, adopt the method for welding to be connected with tubing afterwards, though can guarantee end enclosure structure size and performance requirement, the production process complexity expends lot of manpower and material resources.
Along with progress of science and technology and development, spinning process has obtained studying widely and using, and for the processing of centrosymmetric thin wall component, spinning is one of best process means, be a kind of efficiently, practical art technology cheaply.For the shaping spinning of tubing or seal, generally adopt special-purpose spinning machine, adopt cold spinning or workpiece heating furnace to uniform temperature, adopt two-wheeled or many wheels to carry out part forming spinning, need carry out a large amount of equipment and drop into, thereby cost is increased.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the object of the present invention is to provide a kind of process of pipe end high speed rotation press closing, this method is simple, efficient, can realize the tubing end sealer than minor diameter, control the shape of spinning closing-in effectively, realize high-precision tubing rotation press closing.
In order to realize the rotation press closing of tubing, technical scheme of the present invention is:
A kind of process of pipe end high speed rotation press closing comprises following step,
The clamping fixing step is sealed shape according to tubing and is manufactured and designed spinning wheel, and spinning wheel is installed on the lathe saddle, utilizes the scroll chuck of lathe and centre frame that tubing is carried out clamping and location then;
The port heating steps, heat at the position of adopting heater need seal the tubing end, and tubing slowly rotates in the heating process, is heated to the rubicundity state until tubing;
The spinning step, after the tubing heating is finished, accelerate the rotary speed of tubing simultaneously, when tubing is with the lathe rotation, with the spinning wheel that is installed on the knife rest tubing is pushed, carry out axial feed by lathe control spinning wheel, manually control radial feed, tubing is carried out necking in, and shape is reciprocating in accordance with regulations to make spinning wheel;
Sealing step, according to the spinning situation, work-piece cools hardness is too high, when rotary pressure deformation is not enough, can utilize repeatedly that heater heats, spinning process, when spinning closed up to the later stage, the recessed edge face of spinning wheel extrude tubes simultaneously axially the tubing sealing part being applied certain pressure, makes its closing in.
Further, described heater is the oxyacetylene torch spray gun.
Further, the heated temperatures of tubing is 700 ℃～800 ℃ in the described port heating steps.
Further, the rotary speed of tubing is 400-600rpm in the described spinning step.
Beneficial effect of the present invention and advantage are:
1, adopts simple process to solve the rotation press closing problem of tubing, be particularly suitable for sealing than the 30CrMnSiA of minor diameter and the rotation press closing tubing of other ferrous metal pipe material.
2, under the situation of and small lot batch manufacture comparatively single at product, need not special-purpose spinning machine and firing equipment, adopt engine lathe to carry out spinning and oxy-acetylene heating, can adopt roughing feed to process, greatly reduce cost.

The specific embodiment
Embodiment: selecting 30CrMnSiA tubing φ 60 * 5 rotation press closings for use is example, and its technical process is:
1. as Fig. 1, manufacture and design spinning wheel 4 according to the situation of sealing, and spinning wheel 4 is installed on the lathe saddle 5.
2. as Fig. 1, utilize the scroll chuck 1 of lathe and 3 pairs of tubing of centre frame 2 to carry out clamping and location.
3. as Fig. 3, heat at the position of adopting 9 pairs of tubing 2 ends of oxyacetylene torch to seal, and tubing 2 slowly rotates in the heating process, is heated to rubicundity state (about 700 ~ 800 ℃) until tubing 2.
4. stop the heating of 9 pairs of tubing 2 of oxyacetylene torch, accelerate the rotary speed (about 400 ~ 600rpm) of tubing 2 simultaneously.
5. as Fig. 4, adopt 7 pairs of tubing 2 of spinning wheel flange surface to push, carry out axial feed by lathe control spinning wheel 4, manually control spinning wheel 4 radial feeds, tubing 2 is carried out necking in.
6. as shown in Figure 5, according to the spinning situation, work-piece cools hardness is too high, when rotary pressure deformation is not enough, can adopts and carry out repeatedly that oxyacetylene torch 9 heats, spinning process.
7. when spinning to the later stage closed up, recessed edge face 6 extrude tubes 2 of spinning wheel simultaneously axially tubing 2 sealing parts being applied certain pressure, made its closing in.
The process of rotation press closing is a kind of typical continuous local plastic forming technique, and the spinning wheel pressurizing unit of simplicity of design is with its hydrostatic profile, product precision height, craft flexibility is good, be easy to realize plurality of advantages such as mechanization and automation and the important development direction that becomes plastic forming, it is the advanced manufacturing technology that realizes few no machining of Thin-wall Revolving Part, this method deformation force is little, this technology has process characteristics such as forging, extruding, stretching, bending, ring pressure, horizontal bundle and roll extrusion, to finish the processing of part.
