Description

Technical Field

[0001] The utility model belongs to the technical field of styrene-butadiene rubber detection, in particular to high tensile strength styrene-butadiene rubber detection equipment. Background Art

[0002] The physical properties, processing properties and product performance of styrene-butadiene rubber are close to those of natural rubber. Some properties, such as wear resistance, heat resistance, aging resistance and vulcanization speed, are better than those of natural rubber. It can be used together with natural rubber and a variety of synthetic rubbers. It is widely used in the production of tires, tapes, hoses, wires and cables, medical devices and various rubber products. It is the largest general synthetic rubber variety. With the development of science and technology, a series of styrene-butadiene rubbers with high tensile strength have emerged. Such styrene-butadiene rubbers need to be tested for tensile strength before leaving the factory. The existing tensile strength test has realized information-based automatic detection and processing.

[0003] For example, patent application number CN201922221124.3 discloses a computer tensile testing machine for chloroprene rubber and styrene-butadiene rubber nanocomposite rubber, comprising a fuselage, on which an upper clamping end and a lower clamping end are disposed opposite to each other, and a square groove is disposed at one end of the upper and lower clamping ends, and a square left clamping plate and a square right clamping plate are disposed in the square groove, both of which are in contact with the bottom of the square groove, and a device for making the left and right clamping plates gather or disperse and move mutually is disposed on the wall of the square groove. The utility model is used to detect the tensile strength of chloroprene rubber and styrene-butadiene rubber nanocomposite rubber, and can strengthen the firmness of the upper and lower clamping ends to clamp the rubber sample.

[0004] In the prior art, tensile testing of styrene-butadiene rubber is achieved by using multiple clamping ends in conjunction with a computer tensile testing machine. However, there are certain deficiencies during use: the overall structure of the existing tensile testing equipment is thin, and the stability is poor when testing styrene-butadiene rubber with high tensile strength. It is prone to jitter and deviation, and the detection accuracy cannot be guaranteed. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a high tensile strength styrene butadiene rubber testing device. The utility model provides multiple detectors and connecting plates and second slide bars and first slide bars, so that the stability of the testing device when testing the tensile strength of styrene butadiene rubber with high tensile strength is effectively guaranteed, and the rubber is prevented from falling off or the device is shaken during the stretching process, and the detection accuracy is effectively improved.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high tensile strength styrene-butadiene rubber testing device, comprising a base, a support frame is arranged on the upper end face of the base, a plurality of push cylinders are arranged on the end face of the support frame, a slide is slidably arranged below the push cylinder, a plurality of detectors are arranged between the output end of the push cylinder and the slide, a connecting plate is arranged on the bottom end face of the slide and the upper end face of the base, a reference plate is arranged on one side of the adjacent end faces of the two connecting plates, a sliding plate is slidably arranged on one side of the reference plate, and visual probes are arranged on both sides of the connecting plate on the bottom end face of the slide. The setting of multiple detectors and multiple visual probes effectively improves the accuracy of rubber tensile strength detection.

[0007] Preferably, a connecting tube is connected to the bottom output end of the push cylinder, a detector is connected to the bottom of the connecting tube, and the bottom of the detector is connected to the top end surface of the slide table.

[0008] Preferably, two bellows are arranged on both sides of the upper end surface of the base. The arrangement of multiple bellows enables the clamping contact surface between the reference plate and the sliding plate to be cleaned quickly, thereby reducing the occurrence of damage to the clamping surface during the rubber clamping process.

[0009] Preferably, a fixing plate is provided on one side of the upper end surface of the connecting plate, a threaded barrel is provided on the fixing plate, a screw rod is provided on the threaded barrel in threaded cooperation, and one end of the screw rod is rotatably connected to the end surface of the sliding plate. The upper arrangement of the threaded barrel and the screw rod enables the rubber clamping process between the reference plate and the sliding plate to be completed quickly.

[0010] Preferably, a plurality of anti-slip strips are arranged on the adjacent end surfaces of the reference plate and the sliding plate. The arrangement of the plurality of anti-slip strips effectively improves the stability of the rubber clamping.

[0011] Preferably, a plurality of second slide bars are connected to both sides of the end surface of the sliding plate close to the fixed plate, and the second slide bars are slidably arranged on the fixed plate. The arrangement of the second slide bars effectively improves the stability of the sliding plate when it is clamped and slid.

[0012] Preferably, first slide bars are slidably arranged at the four corners of the end surface of the slide, and the first slide bars are connected between the support frame and the base. The arrangement of the first slide bars effectively reduces the occurrence of shaking of the slide during the stretching test.

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Embodiment 1:

[0024] refer to Figure 1-7 A high tensile strength styrene-butadiene rubber testing device comprises a base 10, a support frame 11 is arranged on the upper end surface of the base 10, a plurality of push cylinders 12 are arranged on the end surface of the support frame 11, a slide table 13 is slidably arranged below the push cylinder 12, a plurality of detectors 17 are arranged between the output end of the push cylinder 12 and the slide table 13, a connecting plate 16 is arranged on the bottom end surface of the slide table 13 and the upper end surface of the base 10, a reference plate 20 is arranged on one side of the adjacent end surfaces of the two connecting plates 16, a sliding plate 21 is slidably arranged on one side of the reference plate 20, and visual probes 18 are arranged on both sides of the connecting plate 16 on the bottom end surface of the slide table 13.

[0025] When the styrene-butadiene rubber needs to be tested for tensile strength, the staff can start the equipment. At this time, the output end of the push cylinder 12 will push the detector 17 to move downward, thereby pushing the slide 13 at the bottom of the detector 17 to move downward, thereby pushing the connecting plate 16 at the bottom of the slide 13 and the reference plate 20 and the sliding plate 21 to move to the end surface of the base 10. At this time, the staff can place the rubber between the two connecting plates 16, and then push the sliding plates 21 on the two connecting plates 16, so that the sliding plates 21 on the two connecting plates 16 and the reference plate 20 can clamp the upper and lower ends of the rubber. After the two ends are clamped, the push cylinder 12 will drive the slide 13 and the upper end of the clamped rubber to move upward, thereby applying a tensile force to the rubber. At this time, the detector 17 will detect and process the tensile force to determine the specific tensile strength of the rubber. During this process, the visual probe 18 at the bottom of the slide 13 will record the shape changes of the rubber in real time, thereby assisting in judging the actual detection situation and improving the detection accuracy. In the above relationship, the setting of the reference plate 20 and the sliding plate 21 can clamp most of the rubber, and the setting of multiple detectors 17 and multiple visual probes 18 can effectively ensure the detection accuracy.

[0026] refer to Figure 7 A connecting tube 27 is connected to the bottom output end of the push cylinder 12 , a detector 17 is connected to the bottom of the connecting tube 27 , and the bottom of the detector 17 is connected to the top end surface of the slide table 13 .

[0027] The connecting tube 27 connected to the output end at the bottom of the push cylinder 12 is used to connect the detector 17. The output end of the push cylinder 12 can push the connecting tube 27 to move up and down, thereby driving the detector 17 and the slide 13 to move up and down.

[0028] refer to Figure 5 A fixing plate 22 is provided on one side of the upper end surface of the connecting plate 16 , a threaded barrel 24 is provided on the fixing plate 22 , a screw rod 23 is provided on the threaded barrel 24 in threaded cooperation, and one end of the screw rod 23 is rotatably connected to the end surface of the sliding plate 21 .

[0029] The fixing plate 22 is fixed. When the rubber needs to be clamped to complete the tension test, the staff only needs to rotate the screw 23 clockwise, and one end of the screw 23 will push the sliding plate 21 forward to clamp and fix the rubber. This setting has the same function as a bench vise, which can ensure the disassembly and assembly efficiency and the fixing effect.

[0030] refer to Figure 6 A plurality of second sliding rods 26 are connected to both sides of the end surface of the sliding plate 21 close to the fixed plate 22 , and the second sliding rods 26 are slidably disposed on the fixed plate 22 .

[0031] When the sliding plate 21 slides back and forth to complete the clamping process of the rubber, the sliding plate 21 will also drive the multiple second sliding rods 26 to slide on the fixed plate 22. The setting of the multiple second sliding rods 26 can improve the stability of the sliding plate 21 when moving, thereby improving the clamping stability.

[0032] refer to Figure 5-7 A plurality of anti-slip strips 25 are provided on the adjacent end surfaces of the reference plate 20 and the sliding plate 21 .

[0033] The provision of a plurality of anti-slip strips 25 can effectively improve the clamping effect of the reference plate 20 and the sliding plate 21 on the rubber, and can effectively prevent the rubber from falling off during the tensile test.

[0034] refer to Figure 6 Two bellows 15 are arranged on both sides of the upper end surface of the base 10 .

[0035] The two bellows 15 can perform dust removal on the reference plate 20 and the sliding plate 21 on the two connecting plates 16 before and after the rubber tensile test, thereby preventing dust and dirt from damaging the rubber clamping surface and ensuring the tensile test accuracy.

[0036] refer to Figure 4 A pump 19 is provided on one side of the upper end surface of the base 10 .

[0037] The pump 19 is used to provide power to the plurality of push cylinders 12 . Embodiment 2:

[0038] On the basis of or different from the first embodiment, reference Figure 1 , 4 First slide bars 14 are slidably arranged at the four corners of the end surface of the slide table 13 , and the first slide bars 14 are connected between the support frame 11 and the base 10 .

[0039] The plurality of first slide bars 14 are fixed, and the slide table 13 can slide up and down outside the first slide bars 14 . The arrangement of the plurality of first slide bars 14 can effectively improve the stability of the slide table 13 when it moves up and down, and improve the accuracy of the tensile test.
