Description

Technical Field

[0001] The utility model belongs to the technical field of flat copper wire application, in particular to a flat copper wire sample pressure test tool. Background Art

[0002] Flat copper wire is a copper wire with a rectangular cross-section. It can be used in building electrical distribution box lines, lighting systems, power supply systems, etc. It can also be used as a conductive material for manufacturing mechanical parts. Due to its excellent conductivity, small size, light weight and long service life, it is widely used in various fields.

[0003] When flat copper wire is used in transformers, the transformer coil will be subjected to a radial force due to the action of current during operation. The magnitude of the force depends on the intensity of the current. For sudden current fluctuations, excessive force will cause the transformer coil to deform, thus affecting the stable operation of the transformer. Large transformers mostly use self-adhesive enameled flat copper wire for electromagnetic wire. After the transformer coil is wound, this electromagnetic wire is dried. The self-adhesive paint on the enameled flat copper wire is in a molten state due to heat. At the same time, it will be bonded together under the action of its own pre-tightening pressure, so that the coil fixed only by external force becomes a rigid whole, which increases the bending strength of the entire coil, greatly reduces the possibility of deformation of the coil under force during operation and when the transformer is running, and makes the transformer run more stable.

[0004] Therefore, when producing the self-adhesive enameled flat copper wire, it is necessary to simulate the pressure and temperature conditions of the transformer after winding to test the bonding strength characteristics; when making the bonding strength test sample, it is necessary to calculate the corresponding pressure according to the size of the pressure area and the pressure, and then apply the corresponding pressure to the test sample, and then perform the treatment with both pressure and temperature conditions. Therefore, in order to achieve the above purpose, the utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1 to Figure 5 As shown, the present embodiment aims to provide a tool capable of performing pressure tests on flat copper wires. To this end, the flat copper wire specimen pressure test tool provided in the present embodiment comprises a high temperature box 1 with a front-opening door. The high temperature box 1 can adopt the existing common sealing door 11 at the front end. In order to facilitate observation of the test, in the present embodiment, an observation window 12 is made on the sealing door 11 to facilitate observation of the interior.

[0023] In order to facilitate the assembly of flat copper wires, a work frame 2 is provided in the high temperature box 1. The work frame 2 is a square frame. In this embodiment, it is bolted to the bottom plate of the high temperature box 1. A workbench 3 is provided on the top of the work frame 2. The workbench 3 is provided in a flat plate shape. A slider is provided at the bottom of the workbench 3. Tracks are provided on both sides of the work frame 2. In this way, the workbench 3 can be slid forward and backward on the work frame 2. The main purpose of this arrangement is to facilitate the extraction of the workbench 3 to facilitate the placement of flat copper wires.

[0024] In order to place the flat copper wire, a base 4 is arranged above the workbench 3. The base 4 is also arranged in a rectangular parallelepiped shape. A flat copper wire fixing mechanism is arranged on the base 4. The flat copper wire fixing mechanism is mainly used to stack several flat copper wires.

[0025] In order to apply pressure to the stacked flat copper wires, a weight rod 6 is provided above the flat copper wire fixing mechanism. Considering that it is impossible to place weights in the high temperature box 1 under high temperature conditions, the weight rod 6 is vertically arranged to penetrate the top of the high temperature box 1. In order to prevent the weight rod 6 from falling and to facilitate the placement of weights, a weight plate 61 for placing weights is provided on the top of the weight rod 6.

[0026] Thus, when a test is required, the flat copper wire is first placed on the flat copper wire fixing mechanism, and then the sealing door 11 is closed, and weights are gradually added to the weight plate 61 . At the same time, the temperature in the high temperature box 1 is increased to reach the test requirement, and then the test can be observed through the observation window 12 .

[0027] In order to facilitate the placement of the flat copper wire, in the present embodiment, a flat copper wire fixing mechanism is also specially provided. Specifically, the flat copper wire fixing mechanism includes two fixed rods 41 arranged on the base 4 at intervals on the same side and a movable rod 5 arranged on one side of the fixed rod 41. In the present embodiment, the fixed rod 41 and the movable rod 5 are both arranged in the shape of rectangular plates. A limiting groove 42 for limiting the movement of the movable rod 5 is provided on the base 4. The limiting groove 42 is provided in the middle of the base 4, the fixed rod 41 is provided on the rear side of the limiting groove 42, and the movable rod 5 is provided in the limiting groove 42. In order to facilitate the adjustment of the movable rod 5, in the present embodiment, a connecting plate 51 is provided between the two movable rods 5, the connecting plate 51 is in the limiting groove 42, a driving screw is provided in the limiting groove 42, and a screw nut 53 matching the driving screw is provided on the connecting plate 51. In this way, the distance between the movable rod 5 and the fixed rod 41 can be adjusted by rotating the driving screw rod. When the flat copper wire needs to be placed, the distance between the movable rod 5 and the fixed rod 41 is increased. When testing, the distance between the movable rod 5 and the fixed rod 41 is decreased to facilitate limiting.

[0028] In this embodiment, in order to drive the two movable rods 5 at the same time, a driving mechanism is provided in the base 4, specifically, including an externally exposed driving tube 43 and a driving gear sleeved on the driving tube 43. At the same time, connecting gears are meshed on both sides of the driving gear, and a passive gear is provided on the side of the connecting gear away from the driving gear. The passive gear is sleeved on the screw rod. In this way, the two movable rods 5 can work simultaneously by rotating the driving tube 43.

[0029] Considering that the pressure test is to be performed, a baffle 52 for shielding the limit groove 42 is provided between the movable rods 5. The baffle 52 is provided in a convex shape, so that the baffle 52 shields the limit groove 42 so that the flat copper wire will not be suspended, thereby ensuring the normal conduct of the test.

[0030] Considering that the weight rod 6 affects the pulling out of the workbench 3 to a certain extent, a spring lock bead 62 is provided on the weight rod 6, and an annular groove matching the spring lock bead 62 is provided on the top plate of the high temperature box 1. In this way, when pressure is needed, the weight rod 6 is pushed upward, and the spring lock bead 62 and the annular groove cooperate to prevent the weight rod 6 from falling, thereby leaving space for pulling out the workbench 3.

[0031] In order to ensure the cooperation between the spring lock bead 62 and the annular groove, a limit plate 63 is provided on the weight rod 6, and the limit plate 63 is arranged below the spring lock bead 62. In this way, when the limit plate 63 contacts the top plate, the spring lock bead 62 also extends into the annular groove to form a cooperation.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
