Description

Technical Field

[0001] The utility model belongs to the technical field of cutting, and more specifically relates to a sample shearing device. Background Art

[0002] Existing shearing devices have limitations in adjusting the fixing force, mainly because existing shearing devices rely on springs to provide the fixing force.

[0003] As a mechanical element, the fixing force provided by the spring is constant under the same deformation, which means that no matter what the size or thickness of the specimen is, the force applied by the spring remains unchanged. In practical applications, this unchanging fixing force is not ideal for steelmaking specimens of different sizes and thicknesses; for example, for thinner specimens, the fixing force may exceed the bearing capacity of the specimen. Excessive fixing force may cause the specimen to be crushed or deformed during the shearing process, affecting the accuracy of the test results. For thicker specimens, the fixing force may not reach the holding force of the specimen. The fixing force may not be enough to prevent the specimen from shifting or sliding during the shearing process, which also affects the shearing accuracy. Utility Model Content

[0021] Preferably, the locking member comprises:

[0022] Two first screw rods, the two first screw rods are connected to two ends of the positioning rod;

Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0041] like Figure 1-5 As shown, the utility model provides a sample shearing device, which includes:

During the use of the shearing device, when the shearing device is adapted to steelmaking samples of different thicknesses and sizes to be sheared, the operator can adjust the fixing force of the elastic member 3 according to the specific characteristics of the sample, and when the spring needs to be adjusted When the fixing force of the elastic member 3 is under the same deformation amount, a barrier member 6 is arranged between two adjacent adjustment plates of some adjustment plates 4. Since the two adjacent adjustment plates 4 at the position where the barrier member 6 is installed cannot be extended or retracted, the elastic member 3 at the corresponding position cannot generate elastic force either. The elastic force can only be generated by the elastic member 3 which is not in the limited position. Therefore, the stiffness coefficient of the elastic member 3 can be increased, so that a greater fixing force is generated under the same deformation amount. Therefore, different fixing forces can be used according to the corresponding samples, thereby improving the fixing effect, and effectively avoiding the problem of sample damage or inaccurate shearing due to improper fixing force, thereby improving the shearing quality and efficiency.

[0046] Preferably, the sample shearing device further comprises a support frame 1 , and a cutting plate 2 is slidably connected above the top of the support frame 1 .

Through the adjustment mechanism, the problem of sample damage or inaccurate shearing due to improper fixing force can be effectively avoided, thereby improving the shearing quality and efficiency.

[0063] Preferably, both ends of the baffle 6 are connected with receiving plates 11 , and the two receiving plates 11 are respectively in contact with the opposite surfaces of the two adjustment plates 4 .

[0064] Specifically, the receiving plate 11 is used to increase the contact area with the adjustment plate 4 , thereby ensuring that the barrier 6 is disposed between the two adjustment plates 4 and improving the stability of the barrier 6 .

[0065] like Figure 4 As shown, preferably, the locking member comprises:

[0066] Two first screw rods 8, the two first screw rods 8 are connected to two ends of the positioning rod 5;

[0067] Two nuts 9 are respectively threadedly connected to the two first screw rods 8 , and the nuts 9 can abut against the adjusting plate 4 .

[0068] Preferably, there are two pairs of positioning holes 10 on each adjustment plate 4, and the two positioning holes 10 of each pair are arranged back to back. There are two pairs of positioning rods 5, and each pair of positioning rods 5 can pass through a pair of positioning holes 10. At least one ring body 7 is sleeved on the two positioning rods 5 of each pair.

[0069] Specifically, both ends of the first screw rod 8 are provided with hexagonal grooves 12, and the hexagonal grooves 12 and the first screw rod 8 are coaxially arranged. The ring body 7 can be sleeved on the first screw rod 8, and the ring body 7 is arranged between the nut 9 and the adjustment plate 4, so as to make the ring body 7 abut against the adjustment plate 4. The nut 9 abuts against the ring body 7 at this time, and when the nut 9 is locked, the ring body 7 can be fixed.

[0070] Preferably, the sample shearing device further comprises a plurality of connecting mechanisms, each connecting mechanism being used to connect the top end of an elastic member 3 to one side of the cutting plate 2 .

[0071] Specifically, the design of the connection mechanism ensures the fixation of the elastic member 3 and the cutting plate 2 .

[0072] Preferably, the connecting mechanism comprises:

[0073] A mounting block 13, one end of which is connected to one side of the cutting plate 2;

[0077] In summary, in the existing steelmaking sample shearing technology, sample processing is a crucial step, which is directly related to the accuracy of subsequent testing and analysis. Steelmaking samples are diverse in shape and size. This diversity requires the shearing device to be able to adapt to samples of different thicknesses and sizes. The sample shearing device of the utility model can adapt to the diverse requirements of steelmaking samples. When the sample shearing device of the utility model is used or operated:

[0078] When it is necessary to adjust the fixing force of the elastic member 3 under the same deformation, first install the positioning rod 5 of the corresponding length in the positioning port 10. Since multiple baffles 6 are sleeved on the positioning rod 5 and the receiving plate 11 is in contact with the adjusting plate 4, the ring body 7 is then sleeved on the first screw rod 8 and threadedly connected to the threaded rod 8 through the nut 9. Therefore, the positioning rod 5 can be fixed, and the positioning rod 5 can be confined in the positioning port 10 by the two ring bodies 7. Since the adjusting plate 4 with the baffle 6 installed cannot be extended or retracted, the elastic member 3 at the corresponding position cannot generate elastic force, and the elastic force can only be generated by the elastic member 3 that is not in the fixed position. Therefore, the stiffness coefficient of the elastic member 3 can be increased, so that a greater fixing force is generated under the same deformation. Therefore, different fixing forces can be used according to the corresponding steelmaking samples, thereby improving the fixing effect.

[0079] When cutting is required, the steelmaking sample is placed on the support beam 17 and the main frame 1, and then slid to the position of the cutting plate 2. The pull rod 19 is driven by the telescopic drive member 18 to rotate around the fixed rod 20. Since the connecting plate 21 is rotatably connected to the pull rod 19 and the cutting plate 2, the cutting plate 2 can be driven to slide downward, so that the pressure plate 16 first contacts the steelmaking sample to fix it, and then the cutting is performed through the cutting plate 2 to realize the shearing process.

[0080] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
