Description

Turnbuckle and manufacturing process thereof

The present invention relates to a kind of turnbuckle and manufacturing process thereof, particularly relate to a kind of fence facility center line class of building and set up turnbuckle and the manufacturing process thereof that backguy is used aspect stringing.

In the prior art; being used for building encloses and blocks facility center line class and set up backguy aspect stringing; adopt the traditional approach of artificial colligation, elastic threads mostly; not only labour intensity is big; time-consuming; effort; and, because manual operations occurs by stringing not enough because of artificial tension degree through regular meeting; cause building line class loosening; the ejection phenomenon takes place, and influences the construction quality requirement, building application life and human body is come to harm; when building fence facility center line class is erected at stringing aspect quality requirement when higher, just more difficultly satisfy the high-tech standard-required.

The purpose of this utility model is to provide a kind of structure z simple, easy to use, and processing line is short out, can rapidly building fence facility center line class be set up backguy tension, fixing a kind of turnbuckle and manufacturing process thereof.

The technical solution of the utility model is: a kind of turnbuckle, it comprises housing, ratchet shaft two parts composition, wherein, housing is a U type shape, and the upper end is provided with locking wire and colludes, the lower end is provided with incoming line, two sides, middle place are provided with symmetrical ratchet perforation, and the place is provided with through hole in the middle of the ratchet shaft, and, ratchet shaft is fixed by the ratchet perforation that its two ends are provided with on hook tooth and the housing, and ratchet shaft and housing are joined together.

The turnbuckle manufacturing process is as follows:

The main technique flow process is: shearing blanking, crop, towards the device hole, dash locking and collude, once dash curved, secondary and dash curved, casting ratchet shaft, ratchet shaft and housing are installed, on the riveted joint housing etc., concrete operation method follows these steps to successively:

A, the stretching steel plate that will select, through shearing blanking, cut away drift, go out the device hole, dash that locking is colluded, housing dashes curved, secondary housing and dashes and curve type, makes the turnbuckle housing;

B, adopt casting technique to make ratchet shaft, 1, before reaching pouring furnace, adopt and add low-alloy composition C:2.0-2.4, Si:0.6-0.8, Mn:1.2-1.4 makes it become the low-alloy cast iron molten iron when reaching 1380 ℃ of cast furnace temperature; 2, with in the low-alloy cast iron molten iron casting sand mould model, adopt the typing of damp sand model, folded case casting form, 1380 ℃ of pouring temperatures through supercooling, artificial off-type, put into the mechanical desanding of shot-blasting machine, make ratchet shaft;

C, ratchet shaft is fixed in the middle of the housing, turnbuckle is made in riveted joint housing upper end.

Advantage of the present invention is:

1, simple in structure, easy to operate, can rapidly building fence facility center line class be set up the backguy tension, fixing.

2, adopt the casting technique ratchet shaft shorter than hot investment casting machining process route, cost is low, the efficient height.

Fig. 2 is a structure right view of the present invention;

Fig. 3 is a ratchet structure schematic diagram of the present invention;

Fig. 4 is that ratchet structure A of the present invention is to view;

Below in conjunction with the description of drawings embodiments of the invention:

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of turnbuckle, it comprises housing 1, ratchet shaft 2 two parts composition, wherein, housing 1 is U type shape, the upper end is provided with locking wire and colludes 3, and the lower end is provided with incoming line 4, and two sides, middle place are provided with symmetrical ratchet perforation 5,6, the place is provided with through hole 7 in the middle of the ratchet shaft, and ratchet shaft 2 is fixing by the ratchet perforation 5,6 that its two ends are provided with on hook tooth 8,9 and the housing 1, and ratchet shaft 2 and housing 1 are joined together.One end of hook tooth 8 is provided with the handle 10 that is square shape.

The manufacturing process of turnbuckle:

The main technique flow process is: shearing blanking, crop, towards the device hole, dash locking and collude, once dash curved, secondary and dash curved, casting ratchet shaft, ratchet shaft and housing are installed, on the riveted joint housing etc., concrete operation method follows these steps to successively:

A, the stretching steel plate that will select, through shearing blanking, cut away drift, go out the device hole, dash that locking is colluded, housing dashes curved, secondary housing and dashes and curve type, makes the turnbuckle housing;

B, adopt casting technique to make ratchet shaft, 1, before reaching pouring furnace, adopt and add low-alloy composition C:2.0-2.4, Si:0.6-0.8, Mn:1.2-1.4 makes it become the low-alloy cast iron molten iron when reaching 1380 ℃ of cast furnace temperature; 2, with in the low-alloy cast iron molten iron casting sand mould model, adopt the typing of damp sand model, folded case casting form, 1380 ℃ of pouring temperatures through supercooling, artificial off-type, put into the mechanical desanding of shot-blasting machine, make ratchet shaft;

C, ratchet shaft is fixed in the middle of the housing, turnbuckle is made in riveted joint housing upper end.

Operating principle of the present invention is: the locking wire that housing 1 upper end is provided with colludes 3 and is fixed on the stationary object, the line class material of need tension is fixed on the ratchet shaft 2 by incoming line 4 and the ratchet shaft 2 middle through holes of locating to be provided with 7 that housing 1 lower end is provided with, be rotated counterclockwise the handle 10 of hook tooth 8 ends on the ratchet shaft 1 with spanner, line class material is tightened up, thereby finish the purpose of stringing, and housing 1 adopts metal material to make, and can bear the pulling force in the stringing process.
