Description

Technical Field

[0001] The invention relates to the technical field of steel strip detection, and in particular to a multifunctional steel strip toughness testing device. Background Art

[0002] The steel strips used to produce razor blades need to be tested for toughness during the production process to determine whether the strength of the steel strips after heat treatment meets the standards.

[0003] When using the existing steel belt toughness testing machine to test the toughness of the steel belt, the steel belt is manually fixed. Since the steel belt used to produce razor blades is thin and soft, the steel belt is easily offset during the manual fixing process, resulting in inconsistent tightness of the two long sides of the steel belt after being clamped. The existing steel belt toughness testing machine cannot correct the offset steel belt, resulting in uneven force when the steel belt is subjected to pulling force. When the steel belt is subsequently subjected to a cutting toughness test, the cutter will first apply pressure to the tighter clamped side, making it easy for the steel belt to be cut from the tighter clamped side, thereby reducing the accuracy of the cutting toughness test value of the steel belt. Summary of the invention

The fitting part 2003 is called; each fixed block 2 is provided with a first driving member 3, and the first driving member 3 is an electric push rod; a clamping block 4 is bolted to the telescopic end of each first driving member 3; each clamping block 4 is located between two fixed parts 2001 of the same fixed block 2; the fixed block 2 is connected with a correction component; each clamping block 4 is provided with a connecting block 5; each fixed part 2001 located at the lower side is provided with another connecting block 5; each connecting block 5 is provided with a plurality of limit rods 5001. The cutting component includes a slide rail 101, an electric slider 102, a pressure sensor 103, a fixing clamp 104 and a blade 105; a slide rail 101 is fixedly connected to the testing machine 1; an electric slider 102 is slidably connected to the slide rail 101; a pressure sensor 103 is fixedly connected to the electric slider 102; a fixing clamp 104 is fixedly connected to the lower side of the pressure sensor 103; and a blade 105 is bolted to the lower side of the fixing clamp 104.

[0020] It also includes an electric slider 106 and a carrier plate 107 ; the electric slider 106 is slidably connected to the slide rail 101 ; the carrier plate 107 is fixedly connected to the electric slider 106 ; an avoidance groove is opened on the carrier plate 107 , and the avoidance groove is directly opposite to the blade 105 .

[0021] The activity detection component includes a slide rail 201, an electric slider 3 202 and a tension sensor 203; the slide rail 201 is fixedly connected to the testing machine 1; two electric sliders 3 202 are slidably connected to the slide rail 201 and are symmetrical on the left and right; each electric slider 3 202 is fixedly connected to a tension sensor 203; each fixed block 2 is fixedly connected to the corresponding tension sensor 203.

[0022] The front side of each movable groove 2002 is configured to be flared to facilitate the insertion of the steel belt into the movable groove 2002 .

[0023] Each fitting portion 2003 is configured to be in a convex arc shape, which is beneficial for reducing the friction force when the steel belt slides on the fixing portion 2001.

[0024] The correction assembly includes a second driving member 301 and a push block 302; each fixed portion 2001 is fixedly connected to a second driving member 301, and the second driving member 301 is an electric push rod; a push block 302 is fixedly connected to the telescopic end of each second driving member 301; each push block 302 slides in the corresponding movable groove 2002.

[0025] Each clamping block 4 is provided with a frosted layer, which is beneficial to enhancing the clamping and fixing effect of the clamping block 4 on the steel belt.

[0026] When testing the toughness of the steel strip, the telescopic end of the first driving member 3 is controlled to drive the clamping block 4 to move to the middle of the fixed block 2, such as Figure 3 As shown, the staff then inserts the two sides of the steel strip to be cut for toughness test into the movable grooves 2002 on the upper sides of the two fixed blocks 2 from front to back. When the steel strip is inserted into the movable groove 2002, the front side of the movable groove 2002 is set to be expanded to facilitate the insertion of the steel strip into the movable groove 2002. When the steel strip is inserted into the movable groove 2002, since the steel strip used to make the razor blade has a certain elastic force, the steel strip can be stuck on the upper fixing part 2001 through its own elastic force, and the steel strip is aligned with the fitting part 2001 on the corresponding fixed block 2. 003 is tightly attached, and the fitting part 2003 limits the upper and lower sides of the steel strip. Then the staff will respectively insert the two sides of the steel strip that needs to be tensile tested into the movable grooves 2002 on the lower sides of the two fixed blocks 2, so that the steel strip is stuck on the fixed part 2001 on the lower side through its own elastic force, and make the steel strip contact with the corresponding fitting part 2003 on the lower side, completing the loading operation before the steel strip is tested. It should be noted that the bearing plate 107 is located between the two steel strips, and the lower sides of the two steel strips are overlapped on the corresponding limit rods 5001 away from the fixed block 2.

[0027] After the two steel belts are placed, the telescopic end of the second driving member 301 is controlled to drive the push block 302 to move forward in the movable groove 2002. Since the steel belt is tightly fitted with the fitting portion 2003 on the corresponding fixed block 2 through its own elastic force, the steel belt is fixed in the movable groove 2002. The push block 302 pushes the rear side of the steel belt stuck in the position to push the two ends of the steel belt forward in the movable groove 2002, so that the two ends of the steel belt move forward synchronously, and then the steel belt is corrected and aligned based on the two ends of the steel belt to prevent the steel belt from being clamped and fixed in an inclined state, so as to avoid the steel belt from being tilted during the subsequent cutting and stretching tests. The uneven force ensures the accuracy of the steel strip toughness test value. In summary, the present invention only needs to manually place the steel strip in the movable groove 2002, and the equipment can automatically correct the steel strip to prevent the steel strip from being offset due to manual placement, thereby avoiding affecting the accuracy of the detected steel strip toughness value, and no manual correction is required. Manual correction is limited by the thin and soft nature of the steel strip, and there is also a situation of offset after correction. For example, during manual correction, one end needs to be corrected first, but when the corrected end is clamped and fixed, the other end is in an active state, which is easy to pull the corrected end to cause offset, and manual correction increases labor.

[0028] When both steel strips are corrected, the telescopic end of the first driving member 3 is controlled to drive the clamp block 4 to move upward, so that the clamp block 4 squeezes the steel strip to fit it to the bottom of the fixing portion 2001 on the upper side, thereby clamping and fixing the steel strip that needs to be cut toughness tested. Then, the electric slider 106 is controlled to drive the carrier plate 107 to slide upward on the slide rail 101, so that the carrier plate 107 fits the lower side of the steel strip to be cut to support the steel strip. Then, the electric slider 102 is controlled to slide downward on the slide rail 101, so that the electric slider 102 drives the fixing clamp 104 and the blade 105 to move downward. Approaching the steel strip, the electric slider 102 drives the blade 105 to fit the middle of the upper side of the steel strip, so that the blade 105 cuts the steel strip and presses the blade 105 down into the avoidance groove on the supporting plate 107 to cut and break the steel strip. In this process, the steel strip is supported by the supporting plate 107 to prevent excessive deformation of the steel strip during the cutting process, so as to avoid affecting the accuracy of the steel strip cutting toughness test value. In the process of cutting the steel strip, the maximum pressure in the process of cutting the steel strip is recorded by the pressure sensor 103 and transmitted to the testing machine 1 for recording, thereby completing the cutting toughness test of the steel strip.

[0029] It is also considered that the two ends of the existing steel strip are only clamped and fixed by a clamp. When the steel strip is subjected to a tensile toughness test, in order to ensure the clamping and fixing effect of the steel strip, the clamp will apply a large clamping force to the steel strip, thereby increasing the friction between the clamp and the steel strip. However, in the process of stretching the steel strip, the clamped position of the steel strip will not only be subjected to tension, but also to the friction force of the clamp on the steel strip to stabilize the clamping, thereby subjecting the clamped position of the steel strip to a large stress, causing the steel strip to break at the clamped position due to the influence of the clamping stress, thereby affecting the accuracy of the tensile toughness test value of the steel strip. The specific solution process is as follows: After the cutting toughness test of the steel strip is completed, the telescopic end of the first driving member 3 is controlled to drive the clamping block 4 to move downward to release the clamping of the cut steel strip. Then the staff removes the cut steel strip from the fixing part 2001. At this time, the first driving member 3 is controlled to drive the clamping block 4 to move downward so that the clamping block 4 presses the other steel strip down to fit the upper part of the fixing part 2001 on the lower side. During this process, the clamping block 4 drives the connecting block 5 to move downward and approach the connecting block 5 on the lower fixing part 2001, so that the two limit rods 5001 on the upper side move downward and approach the limit rods 5001 on the lower side. The two limit rods 5001 squeeze the steel strip through the limit rods 5001, so that the two ends of the steel strip to be stretched are bent in the up and down directions. As the clamp block 4 continues to move downward and approaches the fixed part 2001, the clamp block 4 clamps and fixes the steel strip that needs to be tested for tensile toughness. After the two ends of the steel strip are fixed, the two electric sliders 3 202 are controlled to move away from each other on the slide rail 2 201, thereby driving the two fixed blocks 2 to move away from each other to stretch the steel strip. In this process, the steel strip is squeezed by the limit rods 5001, so that the steel strip is clamped by the clamp block 4 and the fixed part. The stress on the clamping position of the part 2001 is dispersed to the limit rod 5001. The two limit rods 5001 that squeeze and deform the steel strip, and the clamping position of the clamping block 4 and the fixed part 2001 on the steel strip, jointly bear the friction force when the steel strip is clamped stably, which is beneficial to reduce the stress on the steel strip alone at the clamping position of the clamping block 4 and the fixed part 2001, prevent the steel strip from being broken at the clamping position of the clamping block 4 and the fixed part 2001 due to the influence of the stress, avoid deviation in the tensile toughness test value of the steel strip, and ensure the accuracy of the tensile toughness test value of the steel strip. When the steel strip is stretched and broken, the maximum pressure during the stretching of the steel strip is recorded by the tension sensor 203 and transmitted to the testing machine 1 for recording. Then the staff controls the first driving member 3 to loosen the clamping block 4 to fix the steel strip, and removes the tested steel strip from the fixing part 2001, thereby completing the tensile toughness test of the steel strip. The present invention can not only realize automatic correction of the steel strip to prevent the steel strip from deviating and affecting the test results, but also perform tensile toughness test on the steel strip on the basis of the cutting toughness test of the steel strip, thereby realizing the multifunctional integration of the steel strip test items.

[0030] Embodiment 2: on the basis of embodiment 1, as Figure 2-Figure 6 As shown, a limiting block 303 is also included; all the limiting rods 5001 on each connecting block 5 are commonly connected to a limiting block 303 .

[0031] Taking into account the different widths of the steel strips to be tested, in order to enhance the adaptability of the equipment, a damping sliding connection is specifically adopted between the limit block 303 and the limit rod 5001, so that the limit block 303 can slide and adjust on the limit rod 5001 to adapt to steel strips of different widths, while ensuring the fixing effect of the limit block 303 on the limit rod 5001.

[0032] When the staff places the steel belt in the movable groove 2002, the staff lifts up the contact position between the steel belt and the limit rod 5001, so that the steel belt passes the limit block 303 and is stuck in the movable groove 2002. When the steel belt is subsequently pushed by the push block 302 for correction, the lower side of the steel belt overlaps the upper side of the limit rod 5001 away from the fixed block 2 and moves forward. At this time, the push block 302 continues to push the steel belt forward, so that the front side of the steel belt contacts the limit block 303. When the push block 302 pushes the back side of the steel belt to correct the back side of the steel belt, the limit block 303 is used to block and limit the front side of the steel belt to correct the front side of the steel belt, thereby enhancing the correction effect of the steel belt and improving the accuracy of the steel belt toughness test value.
