A simple manual bending test device

Abstract

This utility model discloses a simple manual bending test device, belonging to the field of bending test technology. It includes two locking sleeves, with a hinge welded between them. Each locking sleeve has an insert sleeve inside. In this utility model, by using the insert sleeves and clamping cover plates, test samples of different diameters can be clamped. By changing the bending mandrel diameter component and using the two locking sleeves in conjunction, the position of the bending mandrel diameter component is controlled. By turning two wrenches, the two locking sleeves swing closer together, bending the test sample inside the insert sleeve. The bent portion of the test sample is obstructed by the bending mandrel diameter component, causing the test sample to fit tightly against the outer periphery of the bending mandrel diameter component, bending the test sample to the required diameter. By using bending mandrel diameter components of different diameters, it is possible to manufacture single and double-numbered samples, as well as large and small diameter samples, achieving a wider range of bending test sample manufacturing capabilities.

Description

Technical Field

[0001] This utility model relates to the field of bending test technology, and more specifically, to a simple manual bending test device. Background Technology

[0002] Bending tests are tests used to determine the mechanical properties of materials under bending loads and are one of the fundamental methods for testing the mechanical properties of materials. Currently, instruments used for bending tests on the market are generally designed for common test samples, such as ribbed steel bars and plain round steel bars. These instruments offer the advantage of relatively stable bending diameters. However, the diameters they primarily cover are generally even numbers such as "...16, 18, 20, 24, 32, 40, 48, 56, 64...", and they generally cannot test odd numbers, decimals, or small diameters. Therefore, it is necessary to propose a simple manual bending test device to solve this problem. Utility Model Content

[0004] To solve the above problems, the present invention adopts the following technical solution: a simple manual bending test device, comprising two locking sleeves, a hinge welded between the two locking sleeves, an insertion sleeve provided inside each of the two locking sleeves, a test sample fitted inside the inner cavity of each insertion sleeve, a mating groove provided in the middle of each locking sleeve, a clamping cover plate fitted inside the inner cavity of the mating groove, a threaded connecting rod movably fitted on the clamping cover plate, a reinforcing plate provided in the middle of the lower side of each locking sleeve, the bottom end of the threaded connecting rod penetrating the bottom of the locking sleeve and threadedly connected to the reinforcing plate, a wrench rod provided at the end of each locking sleeve away from the hinge, a magnetic block provided at the end of one locking sleeve near the hinge, the magnetic block contacting the other locking sleeve, and a bending core diameter component provided between the two locking sleeves.

[0005] As a preferred embodiment of this utility model, a sealing cover is provided at the end of the locking sleeve away from the hinge. The sealing cover is movably connected to the wrench lever. A threaded connecting rod II is threadedly connected to the sealing cover, and one end of the threaded connecting rod II is threadedly connected to the locking sleeve.

[0006] In a preferred embodiment of this utility model, the magnetic block is made of permanent magnet, and the magnetic block is magnetically attracted to another locking sleeve.

[0007] As a preferred embodiment of this utility model, the reinforcing plate is provided with a threaded connection hole in the middle, the bottom of the locking sleeve is provided with a through hole, and the bottom end of the threaded connecting rod passes through the through hole and is threaded into the threaded connection hole.

[0008] As a preferred embodiment of this utility model, a silicone pad is provided at the bottom end of the clamping cover plate, and several clamping teeth are provided on the lower side of the silicone pad and in the middle of the inner cavity of the insertion sleeve.

[0009] As a preferred embodiment of this utility model, a pressure plate is sleeved on the outer side of the top of the threaded connecting rod.

[0010] As a preferred embodiment of this utility model, an extension sleeve is fitted on the outer side of the wrench handle.

[0011] The advantages of this utility model are as follows: In this utility model, by using the plug-in sleeve and clamping cover plate, test samples of different diameters can be clamped. By changing the bending core diameter part and using the two locking sleeves in cooperation, the position of the bending core diameter part can be controlled. By turning the two wrench levers, the two locking sleeves swing closer together, and the test sample inside the plug-in sleeve is bent. The bent part of the test sample is hindered by the bending core diameter part, so that the test sample fits tightly against the outer periphery of the bending core diameter part, and the test sample is bent to the required diameter. By cooperating with bending core diameter parts of different diameters, it is possible to complete the manufacturing of single and double number and large and small diameter models, and realize the manufacturing of bending test samples with a wider range.

[0018] Please refer to Figures 1-2. A simple manual bending test device includes two locking sleeves 1, with a hinge 15 welded between them. Each locking sleeve 1 has an insert sleeve 2 inside, and a test sample 14 is fitted inside the inner cavity of each insert sleeve 2. Each locking sleeve 1 has a mating groove 4 in the middle, and a clamping cover plate 7 is fitted inside the inner cavity of the mating groove 4. A threaded connecting rod 10 is movably fitted on the clamping cover plate 7. A reinforcing plate 3 is provided in the middle of the lower side of each locking sleeve 1. The bottom end of the threaded connecting rod 10 passes through the bottom of the locking sleeve 1 and is threadedly connected to the reinforcing plate 3. A wrench lever 12 is provided at the end of each locking sleeve 1 away from the hinge 15. A magnetic block 16 is provided at the end of one locking sleeve 1 near the hinge 15, and the magnetic block 16 contacts the other locking sleeve 1. A bending core diameter piece 17 is provided between the two locking sleeves 1.

[0019] In this embodiment, by using bending cores 17 of different diameters, it is possible to manufacture single and double-number models as well as large and small diameter models, thereby enabling the manufacture of bending test samples with a wider range of diameters.

[0020] Specifically, please refer to Figures 1 and 2. A locking sleeve 1 has a closing cover 6 at one end away from the hinge 15. The closing cover 6 is movably connected to the wrench lever 12. A threaded connecting rod 5 is threadedly connected to the closing cover 6. One end of the threaded connecting rod 5 is threadedly connected to the locking sleeve 1.

[0021] In this embodiment, the threaded connecting rod 5 is screwed to connect with the locking sleeve 1, so that the sealing cover 6 covers the opening of the plug sleeve 2 and the plug sleeve 2 is sealed. The locking sleeve 1 is provided with a screw hole that matches the threaded connecting rod 5.

[0022] Specifically, please refer to Figures 1 and 2. The material of the magnetic block 16 is a permanent magnet, and the magnetic block 16 is magnetically attracted to another locking sleeve 1.

[0023] In this embodiment, one locking sleeve 1 is attracted to another locking sleeve 1 by a magnetic block 16.

[0024] Specifically, please refer to Figure 2. The reinforcing plate 3 has a threaded connection hole 18 in the middle, and the locking sleeve 1 has a through hole 19 at the bottom. The bottom end of the threaded connecting rod 10 passes through the through hole 19 and is threaded into the threaded connection hole 18.

[0025] Specifically, please refer to Figure 2. A silicone pad 8 is provided at the bottom of the clamping cover plate 7, and several clamping teeth 9 are provided on the lower side of the silicone pad 8 and in the middle of the inner cavity of the plug sleeve 2.

[0026] In this embodiment, turning the threaded connecting rod 10 causes it to engage with the threaded connecting hole 18 on the reinforcing plate 3, which in turn moves the clamping cover plate 7 downward. The clamping teeth 9 then bite and clamp the test sample 14, thereby locking the test sample 14 and locking both ends of the test sample 14 onto the locking sleeve 1. The elasticity of the silicone pad 8 makes the clamping teeth 9 press the test sample 14 more tightly.

[0027] Specifically, please refer to Figure 2. A pressure plate 11 is sleeved on the outer side of the top of the threaded connecting rod 10.

[0028] In this embodiment, the pressure plate 11 squeezes and clamps the cover plate 7, so that the cover plate 7 can clamp the test sample 14.

[0029] Specifically, please refer to Figure 2. An extension sleeve 13 is fitted on the outer side of the wrench lever 12.

[0030] Working principle: First, adjust both locking sleeves 1 to be horizontal so that the magnetic block 16 on one locking sleeve 1 abuts against the other locking sleeve 1. After removing the cover of the sealing cover 6 and the clamping cover plate 7, insert the bent core diameter piece 17 through the gap between the two locking sleeves 1. Insert the test sample 14 through the end of the insertion sleeve 2 where the sealing cover 6 is located, so that the test sample 14 moves from one insertion sleeve 2 to the other insertion sleeve 2. Then, put the sealing cover 6 on the wrench rod 12, turn the threaded connecting rod 2 5 to connect with the locking sleeve 1, so that the sealing cover 6 covers the opening of the insertion sleeve 2 and closes the insertion sleeve 2. Insert the clamping cover plate 7 into the mating groove 4, so that the clamping teeth 9 at the bottom of the mating groove 4 press on the test sample 14. Turn the threaded connecting rod 10 to make the clamping cover plate 7 engage with the inner bottom wall of the insertion sleeve 2, bite the test sample 14, and press and lock the test sample 14, thus making the test sample 14... Both ends are locked to the locking sleeve 1.

[0031] Then, control the position of the bending core diameter component 17, for example, fix the bending core diameter component 17 into a fixed socket, and pull the two wrench levers 12 to make the two locking sleeves 1 swing closer. The test sample 14 inside the insertion sleeve 2 is bent. The bent part of the test sample 14 is hindered by the bending core diameter component 17, so that the test sample 14 fits the outer periphery of the bending core diameter component 17, and the test sample 14 is bent to the required diameter. The test sample inside the insertion sleeve is bent to 180°, and the bending test is completed.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
