[ detailed description ] embodiments

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The invention discloses a single-reel multi-mode secondary wire drawing system for titanium alloy wires, which comprises a paying-off wheel 6, a wire drawing die set, a reel 4 and a wire rewinding machine 3 which are sequentially arranged on a wire drawing line along a titanium alloy wire 2, wherein the wire drawing die set comprises a plurality of rollers; the winding drum 4 is vertically arranged and is in a circular truncated cone or prismoid shape, the small head of the winding drum is positioned below, and the large head of the winding drum is positioned above; a plurality of winding grooves are arranged on the side surface of the winding drum 4 at intervals up and down, and the winding grooves are annular grooves; the wire drawing dies 5 in the wire drawing die set are arranged on the side surface of the winding drum 4 at intervals in a surrounding manner, and each wire drawing die 5 corresponds to one winding groove; the front end and the rear end of each wire drawing die 5 are respectively provided with a wire guide wheel, and the wire guide wheels are used for guiding the titanium alloy wires 2 to the wire drawing die 5 and a wire winding groove or a wire rewinding machine 3; each wire winding groove is used for guiding the titanium alloy wire 2 to the next wire drawing die 5 after being wound for a plurality of circles; the take-up machine 3 is used for providing tension for the titanium alloy wire 2 so as to realize multi-mode drawing of the titanium alloy wire 2 through the wire drawing die 5.

According to the invention, the plurality of winding grooves are uniformly arranged on the winding drum at intervals, so that the titanium alloy wire 3 sequentially passes through each winding groove, the wire drawing die 5 is arranged in each passing gap, and then the wire is taken up by the wire take-up machine 3, so that single-drum multi-mode drawing can be realized, and the drawing efficiency is improved.

Specifically, in this embodiment, the winding drum 4 is in a circular truncated cone shape or a prismoid shape, and the small end is the first input end of the wire, and the large end is the output end of the wire. Through so setting up, can be so that titanium alloy silk material 2 receives different tension when rotating along with the reel at every mould time, can also eliminate the internal stress after 2 drawing of titanium alloy silk material, can adapt to the cold drawing operation of titanium alloy silk material 2.

More specifically, in the present embodiment, the angle α between the oblique edge of the mandrel 4 and the axis thereof satisfies: alpha is more than 0 degree and less than 10 degrees. Too large or too small included angle is not favorable for eliminating the internal stress of the titanium alloy wire.

In order to improve the drawing efficiency, each winding groove corresponds to one wire drawing die 5, and the wires drawn in the last die pass are subjected to internal stress elimination after the rotation of the winding drum 4, so that the drawing in the next die pass can be continued. The number of the wire drawing dies 5 is equal to the number of the wire winding grooves, and the wire drawing dies 5 are uniformly arranged on the periphery of the winding drum 4 at intervals. Since the winding drum 4 is cylindrical, the drawing dies 5 are uniformly distributed around the winding drum 4 at intervals, as shown in fig. 2, in the present embodiment, there are six drawing dies 5, and from a top view, an included angle between a connecting line between two adjacent drawing dies 5 and the axis of the winding drum 4 is 60 °, so that the winding drum is fully utilized.

In actual use, reel 4 is vertical to be set up, and the microcephaly is in the below, consequently, wire drawing mould 5 diminishes in proper order from the diameter of bottom to top, and concrete deflection can specifically set up according to the task demand. The spool 4 can be mounted on a support, each drawing die 5 also being provided with a corresponding support of different height, and the godet wheels are likewise mounted on the supports.

In this embodiment, the quantity of winding groove sets up 5 ~ 8 on reel 4, and every winding groove width sets up at 15 ~ 20mm, and interval between two winding grooves sets up to about 10mm, can coil the silk material of a specification in every inslot and draw, can be equipped with detachable in every winding groove and press from both sides a silk fixture for the fixed silk material of waiting to draw. The number of the wire winding grooves is too small, the processing efficiency is high, and the problems that the internal stress of the titanium alloy wire 2 is difficult to eliminate, the titanium alloy wire is broken and the like can be caused. Specifically, the wire clamping fixture can be screwed with the inner surface of the winding groove, such as the top surface or the bottom surface of the groove, or the axial surface close to the axis of the winding drum.

And winding each specification wire in the groove for 2-5 circles, leading out, passing through a wire guide wheel and a wire arranging device, passing through the next wire drawing die, entering the next wire drawing groove, repeating the steps, leading out from the last groove, and then rewinding on a wire rewinding machine 3 through the wire arranging device. Through set up the winding displacement ware behind every godet roller, can make every pass draw and all have certain silk material surplus, when equipment breaks down, conveniently adjust the length of silk material.

In the production process, after the main motor 8 is started, the winding drum 4 is driven to rotate through the transmission mechanism 7, the titanium alloy wire 2 passing through the first wire drawing die 5 is drawn into the first wire winding groove through a wire clamping fixture in the wire winding groove, the machine is stopped after being wound for 5 circles, the number of winding circles can be judged according to experience, and the main function is to adjust the tension received by the titanium alloy wire 2.

The leading-out wire head of the wire clamping fixture is loosened to pass through the second wire drawing die after bypassing the wire guide wheel, and when the leading-out wire head passes through each wire drawing die, the head of the wire material and a section close to the head of the wire material need to be processed firstly, so that the titanium alloy wire material can pass through the wire drawing die 5. And then, drawing the filament head into a second groove by using a filament clamping fixture, starting the machine, coiling for 5 circles, stopping the machine, loosening the filament clamping fixture, leading out the filament head, passing the filament head through a third filament drawing die 5 after the filament head is wound around a filament guide wheel, repeating the steps until the filament head is coiled for 5 circles in the last groove, stopping the machine, loosening the filament clamping fixture, drawing the filament head, passing a strand guide device, and rewinding the filament head on a wire rewinding machine 3.

After all the wires are fixed, the main motor 8 (driving the winding drum 4 to rotate) and the tension motor 1 (driving the take-up machine 3) are started to rotate at the same time, and drawing work is started until the last die drawing of the wires is finished.
