The specific embodiment
Below in conjunction with embodiment, the technical solution of the utility model is further described:
A kind of damping type draw drum as depicted in figs. 1 and 2, mainly comprise rotation draw drum 4, damping arrangement 3 and chassis 1, wherein damping arrangement 3 is fixed on the below of rotation draw drum 4, there is the revoling tube 5 of a upper sealing under shed at the center of rotation draw drum 4, rotation draw drum 4 is placed on the center shaft 2 that is fixed on chassis 1 by revoling tube, for convenient rotation draw drum 4 rotations, center shaft 2 tip designs are become to hemisphere face.
The damping arrangement of this damping type draw drum as shown in Figure 3 and Figure 4, comprising: square member, two band-type brakes 10, set square 8 and pressure adjustment means 9.Wherein:
Square member is to be formed by connecting by four little movable axis 13 by the first active pull rod 7a, the second active pull rod 7b, the 3rd active pull rod 7c and the 4th active pull rod 7d, when pressure adjustment means 9 does not arrange pressure, its square member is that the second active pull rod 7b and the 4th active pull rod 7d are perpendicular to a right-angled trapezium of the first active pull rod 7a;
Two band-type brakes 10 are arranged on the second active pull rod 7b and the 4th active pull rod 7d correspondence position by large movable axis 12, it is made by wear-resisting and the large material of friction coefficient, and be a kind of fan-shaped concave surface, its fan-shaped amplitude radius just equates with the radius of center shaft 2;
Set square 8, the side that it is fixed on the 4th active pull rod 7d of square member, its objective is for fixation pressure adjustment means 9;
Pressure adjustment means 9, comprise adjusting yoke 14, spring 15, rotating nut 16, its medi-spring 15 is enclosed within on adjusting yoke 14, and by the pressure baffle 11 on the first active pull rod 7a and the rotating nut 16 that is enclosed within adjusting yoke 14 tops, spring 15 is fixed on adjusting yoke 14.The bottom of adjusting yoke 14 is connected with set square 8 by little movable axis 13, and is fixed on square member by the pressure baffle 11 on set square 8 and the first active pull rod 7a.Wherein, in order to facilitate secured adjusted pull bar 14 and spring 15, pressure baffle 11 is designed to have the inclination angle of 10 °～30 ° with the straight line at the first active pull rod 7a place.
When regulating the 16 pairs of springs 15 of rotating nut in pressure adjustment means 9 to compress, spring 15 after compression reacts on the first active pull rod 7a, make the deformation of square member, unexpectedly make the spacing that is arranged on two band-type brakes 10 on the second active pull rod 7b and the 4th active pull rod 7d correspondence position reduce, when square member is deflected into a certain degree, the fan-shaped concave surface close contact of two band-type brakes 10, on center shaft 2, and has certain pressure each other.
When this damping type draw drum carries out setting-out work, first regulate the spring in pressure adjustment means 9, band-type brake 10 is contacted with center shaft and have certain pressure-acting, then will need of silk thread of unwrapping wire to be connected on draw bench, then start the switch of draw bench, at this moment, intrinsic resilient property due to some silk thread (as titanium alloy wire) self, perhaps, the rotating speed of this damping type draw drum there will be sometimes fast and sometimes slow, silk thread on its rotation draw drum 4 there will be the phenomenons such as pine is random, at this moment slowly regulate the rotating nut 16 of pressure adjustment means 9, spring 15 is compressed, the effect of increasing to pressure baffle pressure, with this, strengthen the application force of 10 pairs of center shafts 2 of two band-type brakes, with this, increase the friction force between it, when damping type draw drum is synchronizeed and rotated with draw bench, when the silk thread on rotation draw drum 4 there will be the phenomenons such as pine is random to disappear, complete adjusting, this damping type draw drum can work.
