Abstract
The invention discloses a cold drawing clamping and supporting device for stainless steel pipes. The cold drawing clamping and supporting device comprises two clamping plates. Semicircular arc surfaces are arranged on the inner side of each clamping plate, the two clamping plates are used for clamping and supporting the stainless steel pipes, the two clamping plates are provided with free ends and connecting ends and are hinged to each other by the connecting ends, the connecting ends are connected with a locking mechanism, and the locking mechanism comprises a locking spring; when the locking spring is compressed, the free ends of the two clamping plates are in contact with each other, and a barrel can be formed by the two clamping plates in an enclosed manner; when the compression spring is not compressed, the free ends of the two clamping plates are separated from each other. The cold drawing clamping and supporting device has the advantages that inconsistence of the heights of the super long stainless steel pipes or falling of the super long stainless steel pipes in drawing procedures can be prevented by the clamping and supporting device, and accordingly the drawing quality can be guaranteed.
Description
Technical field
The present invention relates to a kind of stainless steel tube cold-drawn folder and hold up device.
Background technology
Cold-drawn is the important production ways of one of steel pipe, cold-draw equipment is drawbench mainly, be blank steel pipe before cold-drawing seamless tube, flat, the toe of one end hammer of the blank steel pipe processed needing cold-drawn, to enable blank steel pipe stretch out the external mold nib of drawbench, enable cold-drawing trolley clamp tup and carry out cold-drawn, this technique is generally used till today.Seamless cold drawing steel tube is used as mechanical industry pipe, the industrial pipe of petroleum geology, chemical industry pipe, station boiler and heat exchanger tube etc. widely.Along with expanding economy and progress, the range of application of cold drawing steel tube will constantly expand, and demand also can be increasing.
Stainless steel tube is in drawing process, and the stainless steel tube that particularly pipe range is very long, as 60 meters even longer, in order to ensure the pipe workpiece quality after drawing, ensureing the high consistency of tubing and tubing on the way not dropped seem particularly important in drawing process.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of stainless steel tube cold-drawn to press from both sides and holds up device.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Device held up by a kind of stainless steel tube cold-drawn folder, comprise two clamps, inside each clamp, all there is semicircle cambered surface, two described clamps are used for folder and hold up stainless steel tube, described clamp has free end and link, two clamps are hinged by link, described link is connected with a retaining mechanism, described retaining mechanism has locking spring, when compressing described locking spring, the free end of two clamps contacts, and two described clamps enclose cylindrical shape, during uncompressed described locking spring, the free end of two clamps is separated.
Preferably, described clamp inside has the cavity circumferentially arranged, and described clamp inwall is evenly equipped with from the outward extending through hole of described cavity.
Preferably, described clamp bottom is connected with oil line pipe, and described cavity communicates with described oil line pipe.
Preferably, be provided with oil feeding reservoirs below described oil line pipe, protection oil is sprayed to stainless steel tube through oil line pipe, cavity and through hole by power set by described oil feeding reservoirs successively.
Preferably, described power set are oil pump.
Preferably, the free end described in two clamps is fixed by buckle when contacting.Further preferably, described buckle is magnetic buckle.
The beneficial effect that the present invention reaches:
In drawing process when stainless steel tube falls, can compress locking spring downwards, two clamps originally opened are enclosed, and encased by stainless steel tube, drawing terminates, and spring is removed latter two clamp of compressive state and opened, and returns to reset condition; Folder of the present invention holds up device can avoid occurring highly inconsistent in the drawing process of overlength stainless steel tube or dropping, and ensures drawing quality;
Generally for and increase the service life and ensure the quality of stainless steel tube; need at stainless steel pipe surface coating protectant; as antirust oil; protection oil is sprayed to stainless steel tube through oil line pipe, cavity and through hole by power set by oil feeding reservoirs of the present invention successively; stainless steel tube is just coated with in drawing process and is covered with protection oil; reduce orderly operation, and better effects if.

Fig. 2 is that in the preferred embodiment of the present invention, the side structure schematic diagram of device (two clamp free ends contact) held up by folder; Wherein:
1. clamp, 11. cavitys, 12. through holes, 2. retaining mechanism, 21. locking springs, 3. oil line pipe, 4. oil feeding reservoirs, 5. buckle, 6. stainless steel tube.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1-2, device held up by a kind of stainless steel tube cold-drawn folder, comprise two clamps 1, inside each clamp 1, all there is semicircle cambered surface, two clamps 1 hold up stainless steel tube 6 for folder, clamp 1 has free end and link, two clamps 1 are hinged by link, described link is connected with a retaining mechanism 2, and retaining mechanism 2 has locking spring 21, during compression locking spring 21, the free end of two clamps 1 contacts, two clamps 1 enclose cylindrical shape, and during uncompressed described locking spring 21, the free end of two clamps 1 is separated.
Particularly, clamp 1 inside has the cavity 11 circumferentially arranged, and clamp 1 inwall is evenly equipped with from the outward extending through hole 12 of described cavity 11.
Particularly, clamp 1 bottom is connected with oil line pipe 3, and cavity 11 communicates with oil line pipe 3.
Particularly, be provided with oil feeding reservoirs 4 below oil line pipe 3, oil feeding reservoirs logical 4 is crossed power set and protection oil is sprayed to stainless steel tube through oil line pipe 3, cavity 11 and through hole 12 successively.Particularly, power set are oil pump.
Particularly, fixed by magnetic buckle 5 when the free end of two clamps 1 contacts.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
