Detailed Description

The structure of the present invention will be further explained by embodiments with reference to the accompanying drawings. It is to be understood that this embodiment is illustrative and not restrictive.

A steel wire end drag chain for a continuous drawing production line is disclosed, please refer to FIGS. 1-3, and the invention points are: mainly comprises a chain body 2, a pin 3 and a clamping head assembly 1. The chain body adopts a chain structure, and two ends of the chain body are respectively hinged with the pin column and the clamping head assembly through respective pin shafts. The pin column is used for being matched with a pin hole on the upper edge of the wire drawing tank in a plug-in mode, and the clamping head assembly is used for clamping the end portion of a steel wire or an aluminum wire.

The clamping head assembly mainly comprises a clamping seat 1.2, a clamping cover 1.1, two clamping blocks 1.5 and a guide sliding column 1.3. The part of the clamping seat close to one end is provided with a pin shaft hole 1.2.1 which is arranged on a pin shaft of the connecting chain body. The clamping seat is characterized in that the upper end of the clamping seat is provided with a mounting groove 1.2.2 communicated with the other end of the clamping seat, and the mounting groove is formed by two symmetrical inclined planes and two inner circle ring surfaces connected with the two inclined planes. The position symmetry of being connected with two inclined planes on the bottom surface in the mounting groove is provided with direction spout 1.2.3, install in the mounting groove with two direction spout sliding fit's mode symmetry respectively in the lower tip of two grip blocks, parallel arrangement is personally submitted to the inboard of two grip blocks, and the medial surface of two grip blocks preferably adopts the sawtooth surface structure, can increase the frictional force of the medial surface of steel wire end and grip block to improve the fastness of centre gripping. The lower part of the guide sliding column is embedded into the inner side position between the clamping blocks in the installation groove, two sides of the lower part of the guide sliding column are respectively connected with the inner ends of the two clamping blocks through a connecting arm 1.4, specifically, one end of the connecting arm is in rotatable fit with a pin shaft vertically fixed on the guide sliding column, and the other end of the connecting arm is in rotatable fit with a pin shaft vertically fixed at the inner end of the clamping block (far away from the position of the inner side face of the clamping block). The centre gripping lid passes through the fix with screw in the top position of mounting groove on the grip slipper, is provided with direction slot hole 1.1.1 on the centre gripping lid, the upper portion of direction traveller is covered the upper end with the mode of following the centre gripping with direction slot hole sliding fit and is stretched out.

By adopting the clamping head assembly, when the guide sliding column is moved inwards, the two clamping blocks are also moved inwards under the drive of the guide sliding column, so that the distance between the inner side surfaces of the two clamping blocks is increased, a steel wire end to be clamped is conveniently 100% inserted between the two clamping blocks, then the guide sliding column is moved outwards, the two clamping blocks are also moved outwards under the drive of the guide sliding column, the distance between the inner side surfaces of the two clamping blocks is reduced, and the clamping of the steel wire end is realized. In order to guarantee the firmness of clamping the end of the steel wire when the steel wire clamping device is used, the guide long hole in the clamping cover can be arranged at a certain inclination, and when the guide sliding column moves to the outer end position, the guide long hole and the guide sliding column form tight fit.

Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit of the invention and the scope of the appended claims, and therefore the scope of the invention is not limited to the disclosure of the embodiments and the accompanying drawings.
