Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a hard pipe strength detection device. Background Art

[0002] Before mass production of hard pipes, a Vickers hardness tester is usually used to test the strength of the early hard pipes to determine whether the strength of the hard pipes meets the production requirements;

[0003] When testing a hard tube with a Vickers hardness tester, the tube to be tested must first be placed directly under the test head. The test head at the top applies pressure to the surface of the tube, and then the groove where the pressure is applied is calculated, thereby determining the strength of the tube.

[0004] However, in the actual testing process, pressure is applied to the hard tube by pressing down the testing head at the top. At this time, the hard tube is horizontally at the top of the test bench, and the bottom end of the hard tube is in an arc shape. During testing, it is not convenient to clamp the hard tube, which causes the hard tube to be displaced during testing, affecting the normal testing of the hard tube. At the same time, after long-term use, some metal debris will remain on the top of the test platform, which is not convenient to clean, resulting in the hard tube contacting the debris during the next use. When pressure is applied to the hard tube during testing, the debris is likely to cause wear on the surface of the hard tube. In view of the shortcomings of the existing technology, we propose a hard tube strength testing device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The embodiment of the present application provides a hard pipe strength detection device, which solves the problem of displacement of the hard pipe during detection and the inconvenience of cleaning the generated debris, thereby avoiding wear on the surface of the hard pipe, thereby protecting the hard pipe and improving the accuracy of hard pipe strength detection.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] The embodiment of the utility model discloses a hard pipe strength detection device.

[0031] According to the attached Figure 1-6As shown, it includes a detection machine body 1, and the detection machine body 1 model adopts HVS-1000Z Vickers hardness tester. The top of the detection machine body 1 is provided with an adjusting pillar 102, and the top of the adjusting pillar 102 is fixedly connected with a test platform 103, and the top of the test platform 103 is provided with a detection head 101. The top two sides of the test platform 103 are slidably connected with clamping plates 2, and a cleaning scraper 3 is provided between the clamping plates 2 on both sides. The cleaning scraper 3 has the function of cleaning waste. A waste box 301 is provided on the outer wall of one side of the test platform 103, and the waste box 301 has the function of collecting cleaned waste. When using the collection, the hard pipe to be tested is placed on the top of the test platform 103, and the placed hard pipe is clamped and positioned by the clamping plates 2 on both sides. Subsequently, a load of a specified size is applied to the top of the hard pipe through the detection head 101 at the top. After maintaining for a period of time, the load is unloaded, and finally the pressure borne by the indentation is measured, so as to detect the hardness of the hard pipe.

[0032] The cleaning scraper 3 is slidably connected to the top end surface of the test platform 103, and a sponge is installed on the inner bottom of the cleaning scraper 3 so that the bottom end of the sponge fits into the top end surface of the test platform 103, so that the cleaning scraper 3 will not wear the test platform 103 during the sliding cleaning process, and the surface of the test platform 103 will be uneven. A driving unit is provided on one side outer wall of the test platform 103, which drives the clamping plates 2 on both sides to slide and clamp the hard pipe. When the clamping plates 2 on both sides are used to clamp the hard pipe, the driving handle 2014 on one side is rotated to drive the internal bidirectional screw 2011 to rotate, so that the driving members 2012 on both sides can drive the clamping plates 2 on both sides to approach each other, so that the clamping plates 2 on both sides clamp and position the two sides of the hard pipe, thereby facilitating the detection head 101 to apply pressure to the hard pipe.

[0033] The drive unit includes:

[0034] A bidirectional screw 2011 is located on one side of the test platform 103;

[0035] A driving member 2012 is slidably connected to the outer peripheral walls on both sides of the bidirectional screw 2011;

[0036] The top ends of the driving members 2012 on both sides are fixedly connected with connecting members 2013, one end of the connecting member 2013 is fixedly connected to one end of the clamping plate 2, and the two ends of the connecting member 2013 are fixedly connected to the clamping plate 2 and the driving member 2012 respectively, which can connect the clamping plate 2 and the driving member 2012.

[0037] The connecting parts 2013 on both sides are slidably connected to the top of the cleaning scraper 3. A rectangular box 201 is fixedly connected to the outer wall of one side of the test platform 103. The rectangular box 201 protects the internal bidirectional screw 2011 and the driving part 2012. The bidirectional screw 2011 is rotatably connected to the inside of the rectangular box 201. One end of the bidirectional screw 2011 is fixedly connected to the driving handle 2014. When the clamping plates 2 on both sides are in a state of being away from each other, the cleaning scraper 3 can slide between the clamping plates 2 on both sides, and then the top of the test platform 103 can be cleaned conveniently without the clamping plates 2 on both sides interfering with the use of the cleaning scraper 3.

[0038] The driving handle 2014 is located on one side outer wall of the rectangular box 201, and a strip groove 3011 is provided on the front outer wall of the test platform 103. The inner wall of the strip groove 3011 is installed with a first magnet 3012. After the strength test of the hard tube is completed, the clamping plates 2 on both sides are driven away from each other and returned to their positions by the driving unit. At this time, the cleaning scraper 3 is located between the clamping plates 2 on both sides. By sliding the cleaning scraper 3 on the top of the test platform 103, the waste remaining at the top can be pushed into the interior of the waste box 301 on one side for collection, which is convenient for cleaning and collecting the waste.

[0039] The inner wall of the waste box 301 is fixedly connected with a mounting piece 3013, and the outer wall of the mounting piece 3013 is installed with a second magnet 3014. The mounting piece 3013 is inserted into the inside of the bar groove 3011, and the first magnet 3012 and the second magnet 3014 are magnetically attracted to each other. When installing the waste box 301, first pick up the waste box 301, align the mounting piece 3013 on one side of the waste box 301 with the bar groove 3011, and insert it into the inside, so that the first magnet 3012 and the second magnet 3014 are magnetically attracted to each other, so that the waste box 301 can be installed.
