Description

Technical Field

[0001] The utility model relates to the field of wire material experiments, in particular to a tensile testing device for wire materials. Background Art

[0002] Wire is a common industrial material, which includes a variety of linear materials such as cables used in power engineering and velvet used in the textile industry. The quality indicators of wire include not only material and density but also tensile strength. Therefore, most of the tensile testing equipment on the market is used to perform tensile tests on it.

[0003] However, in the prior art, since the cable tensile test device is usually simple in structure and cannot stably clamp and fix the wire, the wire is prone to fall off during the tensile process, affecting the accuracy of the experimental data. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a tensile test device for wires.

[0005] In order to solve the above technical problems, the technical solution of the utility model is as follows: a tensile testing equipment for wire, comprising a base, a connecting plate is fixedly connected to the upper edge of the base, an electric push rod is arranged on the right side of the connecting plate, the other end of the electric push rod is fixedly linked to a fixing frame, a threaded column is fixedly connected to one side of the fixing frame, a guide groove is opened on the inner side wall of the fixing frame, a guide rod is slidably connected to the inside of the guide groove, a fixing seat is fixedly connected to the upper end of the fixing seat, a clamping ring is fixedly connected to the outside of the clamping ring, a threaded sleeve is fixedly connected to the upper end of the clamping ring, and a scale block is arranged at the upper end of the base.

[0006] Preferably, rotation grooves are provided on both sides of the fixing seat, short rods are arranged inside the rotation grooves, a fixing rod is sleeved on the outside of the short rods, a bolt is fixedly connected to the lower end of the fixing rod, a limiting ring is sleeved on the outside of the bolt, and a fixing ring is fixedly connected to one side of the limiting ring.

[0007] Preferably, the lower end of the fixing seat is movably connected with a mounting block, a limiting groove is provided inside the mounting block, the lower end of the mounting block is fixedly connected with a short block, and the other end of the short block is fixedly connected with a fixing plate.

[0008] Preferably, the threaded sleeve is movably connected to the fixing seat through a clamping ring and a clamping ring.

[0009] Preferably, the internal thread of the fixing ring is matched with the external thread of the bolt.

[0010] Preferably, the fixing rod is movably connected to the fixing seat via a short rod.

[0011] By adopting the above technical scheme, by rotating the threaded sleeve, under the action of its internal thread and the external thread of the threaded column, the threaded sleeve pushes the retaining ring and the retaining ring to one side, so that one side of the fixed plate is tightly attached to the outside of the wire, thereby fixing the wire. During the movement of the fixed plate, the guide rod slides inside the guide groove, and with the cooperation of the guide rod and the guide groove, the stability of the movement of the fixed plate can be increased. By using the threaded sleeve, retaining ring, retaining ring, fixing seat and threaded column, the position of the fixing plate can be accurately adjusted, thereby achieving firm fixation of the wire. Compared with the traditional method, this fixing method has a better fixing effect, effectively avoids the problem of wire falling off, and ensures the accuracy of the experimental data.

[0012] By rotating the fixing ring and cooperating with the bolt, the limit ring moves away from the mounting block, and the fixing rod can be rotated out of the rotation groove, thereby realizing the separation of the mounting block and the fixing seat. Similarly, during installation, only one side of the mounting block needs to be pressed against the fixing seat and the fixing rod and the fixing ring need to be rotated. The fixing rod will rotate outside the short rod into the rotation groove, and the mounting block will be fixed by the fixing ring and the limit ring to complete the installation of the fixing plate. The fixing plate can be loaded and unloaded by connecting the seat, short rod, fixing rod, bolts, limit ring, fixing ring, etc., and can be replaced when it is damaged, which also reduces the difficulty of replacement.
