Technical Field
The utility model relates to a steel wire winding test equips the field, in particular to a device of keeping silent for steel wire winding.
Background
In national standards of quenching-tempering spring steel wires newly issued in 2018 GB/T18983-2017, equal-diameter winding tests are required to be carried out on quenched and tempered spring steel wires with the nominal diameter of less than 3 mm. However, no special wire-winding tester has been commercially available so far. To complete the winding test, a wire winding test is generally performed on a conventional wire torsion tester. When steel wire winding tests are carried out, various domestic steel wire manufacturers usually directly clamp the core rod steel wire and the wound steel wire in a jaw of the existing steel wire torsion testing machine to finish the steel wire winding tests. The jaw device of the existing steel wire torsion testing machine is designed for a steel wire torsion test, the clamping surface of the jaw is smooth, the jaw device does not have the function of clamping two steel wires simultaneously, and the structure is unreasonable. If the force is too large, the steel wire can be squeezed flat and pinched off, so that the experiment is invalid or retried; if the force is too small, the clamping is not tight, the sliding is loose, and the test cannot be normally carried out. When the former two conditions lead to unstable clamping, the steel wire can slide in the jaw, thereby causing uneven winding; more seriously, the steel wire may be separated from the jaw during winding, and the steel wire rotating at a high speed threatens the personal safety of operators.

Detailed Description
The following describes the present invention with reference to the accompanying drawings.
As shown in fig. 1, the jaw device for winding steel wires of the present invention includes a jaw base 6, two jaw blocks 5 oppositely disposed in an inner cavity of the jaw base 6, a V-shaped groove 51 is disposed in a middle portion of a side surface of one jaw block 5, a clamping groove is formed on the side surface of the V-shaped groove 51 opposite to the other jaw block 5, and at least one clamping hole 52 is disposed on an outer end surface of at least one jaw block.
The material of the jaw block 5 is T9A carbon tool steel with the hardness of HRC 58-62, and other metal materials with the same hardness can be used.
The utility model discloses a theory of operation is: the end faces of two jaw blocks 5 matched with the experimental steel wire are firstly installed in the inner cavity of the jaw base 6 outwards, then the core rod steel wire 3 in the experimental steel wire is inserted into a clamping groove formed by the V-shaped grooves or the side faces of the two jaw blocks 5 which are oppositely arranged, the compression bolt 1 is compressed, and the compression bolt 1 can be used for relatively compressing the two jaw blocks 5 in the inner cavity of the jaw base through the screw passing hole 61. After the core rod steel wire is inserted, the core rod steel wire 3 is ensured not to be loosened and deformed. The wound wire 4 is bent and inserted into the holding hole 52 of the jaw piece 5. The steel wire torsion testing machine is started, after the steel wire torsion testing machine is started, torque is transmitted to the jaw block 5 through the machine body 2, the mandrel steel wire 3 and the wound steel wire 4 are driven to do circular motion, and the purpose of steel wire winding test is further achieved.
Furthermore, V-shaped grooves are formed in the middle of the side faces, opposite to the jaw blocks, of the two jaw blocks, and the two V-shaped grooves are opposite to each other to form a clamping groove. The clamping groove formed by the two V-shaped grooves can be used for clamping steel wires with different diameters to perform experiments, the contact area between the clamping groove and the steel wires is increased, friction force is effectively increased, and clamping is firmer.
Furthermore, the groove surface of the V-shaped groove arranged on one jaw block is provided with anti-skid lines. The anti-slip texture can be a plurality of mutually parallel or mutually staggered straight lines, and can also be other textures which are beneficial to increasing the friction force between the clamping groove and the steel wire.
Furthermore, the included angle of the V-shaped groove arranged on one jaw block is 90-120 degrees. In the current steel wire winding test, the steel wire with the diameter of 1-5mm is often required to be subjected to the winding test. The steel wire with the diameter of 1-5mm is subjected to a winding test, when the included angle of the V-shaped groove is 90-120 degrees, the steel wire winding test is suitable for different steel wire diameters, is not easy to deform and loosen, and can obtain better results.
Further, the outer end faces of the two jaw blocks are respectively provided with a clamping hole, and further, the outer end faces of the two jaw blocks are respectively provided with two clamping holes. Specifically, the clamping holes on the outer end faces of the two jaw blocks may have the same or different hole diameters. When the steel wires of multiple different specifications need to be wound and tested, a plurality of clamping holes can be respectively formed in the two jaw blocks, so that the hole diameters of the clamping holes correspond to the hole diameters of the steel wires one to one, a pair of jaws are suitable for the steel wires of multiple specifications, the frequency of replacing the jaw blocks can be reduced, the testing time is saved, the number of the jaw blocks can be reduced, and the cost is saved.
Further, the clamping holes are round holes or rectangular holes, and specifically, the diameter of the round holes of the clamping holes is 1-5 mm. Steel wires with a circular or rectangular cross-section are the most common type of steel wire, whereas steel wires with a diameter of 1-5mm are the most common gauge in wire winding tests.
Furthermore, the jaw device also comprises two compression bolts, screw through holes are formed in the two sides of the jaw base, and the two compression bolts relatively compress the two jaw blocks through the screw through holes. Specifically, the clamping bolt is used for relatively pressing the jaw block, so that a user can adjust the tightness degree of the clamping bolt according to the clamping condition of the steel wire, the clamping groove can firmly clamp the steel wire, and the serious deformation can not occur.
Further, two opposite jaw blocks arranged in the inner cavity of the jaw base partially extend out. The partly piece of keeping silent that stretches out is favorable to installing the plug steel wire and by the winding steel wire, when carrying out the winding experiment moreover, makes pivoted steel wire keep away from the base of keeping silent relatively, effectively prevents to keep silent the base touching, disturb the steel wire winding.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
