Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of testing devices, in particular to a tool for quickly detecting on-site elongation at break of a rubber seal. Background Art
[0002] During the preparation of rubber seals, under a given formula, different vulcanization times have a significant impact on the hardness of the rubber seals. The longer the vulcanization time, the higher the hardness and the lower the elongation at break. The on-site rapid elongation at break test tool for rubber seals is a rapid on-site testing device designed specifically for rubber seals. It is mainly used to quickly and accurately evaluate the elongation at break performance of rubber seals on the production line or in actual application environments. The on-site rapid elongation at break test tool for rubber seals is a portable or on-site testing device designed to quickly measure the maximum elongation of a rubber seal before it reaches the breaking point during the stretching process, thereby evaluating its elongation at break. This type of tool typically features high precision, ease of operation, and rapid response, making it suitable for quality control and product performance evaluation on production sites.
[0003] In the prior art, testing the elongation at break of rubber seals requires sending finished products to a laboratory for testing. Test samples are randomly selected from the production batch that meet the requirements. Prepare a tensile testing machine that meets the requirements and ensures that the equipment is in good condition and has undergone necessary calibration and initialization settings. Prepare necessary accessories, such as an extensometer, fixtures, and fiducial markers, ensuring that they are intact and suitable for the sample to be tested. Use a fiducial marker to mark the initial gauge length on the sample. This is typically done by marking two parallel lines a certain distance apart in a narrow area of the sample to facilitate elongation measurement during the stretching process. Mount the prepared sample in the fixture of the tensile testing machine, ensuring that the sample is securely clamped in the fixture and that the tensile force is evenly distributed. Set the tensile testing machine parameters, including the stretching speed and load rate. Start the tensile testing machine and gradually increase the load at the set stretching rate until the sample breaks. During the test, record the load change and sample elongation in real time. When the sample breaks, stop the test and record the maximum load and elongation at break.
[0004] In the current process, the finished product needs to be sent to the laboratory for testing every time it is prepared. This process will greatly reduce production efficiency. Utility Model Content

[0011] Preferably, locking nuts are sleeved on the outer sides of the upper and lower clamps.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] When the seal is prepared, it can be fixed on the upper and lower clamps after proper cooling, and then the locking nut is twisted. The rotation of the locking nut can make the openings of the upper and lower clamps smaller, so that it can clamp the seal, and then loosen the limit adjustment nut to adjust the height of the support plate so that the seal is in an extended state, and then tighten the limit adjustment nut, and finally press the drive rod to drive the support plate to move by moving the lifting rod upward, thereby stretching the seal, and manually calculate the elongation at break and the strength at this time according to the initial position and the end position and the corresponding force value, so as to quickly determine whether the seal meets the requirements.
[0014] The advantage of this design is that the seal can be tested by simply clamping and fixing, and pressing the drive rod. The operation is simple and convenient, eliminating the time required to send the finished product to the laboratory, thereby shortening the production cycle and improving production efficiency.

Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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.
[0020] like Figure 1-3 As shown, a tool for quickly testing the on-site elongation at break of a rubber seal comprises a frame 1 , the bottom of the frame 1 is fixedly connected to a base 2 , and the bottom of a force meter 3 is fixedly connected to the base 2 .
[0021] The side walls on both sides of the frame 1 are provided with slide grooves 21, a force meter 3 is provided on one side of the frame 1, and a jack 4 is provided on the other side of the frame 1. The side wall of the jack 4 is fixedly connected to a driving rod 41, and the top of the jack 4 is fixedly connected to a lifting rod 42.
[0022] The interior of the slide groove 21 is slidably connected to the support plate 32, and the upper surface of the base 2 and the lower surface of the support plate 32 are fixedly connected to the upper and lower clamps 5. The openings of a pair of upper and lower clamps 5 are arranged opposite to each other. When the seal is prepared, it can be fixed on the upper and lower clamps 5 after proper cooling, and then the locking nut 51 is twisted. The rotation of the locking nut 51 can make the openings of the upper and lower clamps 5 smaller, so that it can clamp the seal. The outer side of the upper and lower clamps 5 is sleeved with a locking nut 51.
[0023] The top of the lifting rod 42 is set on the bottom of the support plate 32. Both ends of the support plate 32 pass through the slide groove 21 and extend to the outside of the shell frame 1. One end of the support plate 32 extending to the outside of the shell frame 1 is fixedly connected to the support plate 33. The top of the force meter 3 passes through the support plate 33. A scale 34 is engraved on the side of the shell frame 1 close to the force meter 3, and a pointer 35 is engraved on the side of the support plate 33 close to the scale 34.
[0024] The support plate 33 is slidably connected to the side wall of the force meter 3. The side wall of the force meter 3 is threadedly connected with a limit adjustment nut 31. The limit adjustment nut 31 is set on the upper surface of the support plate 33. After fixing the seal, loosen the limit adjustment nut 31 to adjust the height of the support plate 33 so that the seal is in an extended state, and then tighten the limit adjustment nut 31. Finally, press the drive rod 41 to drive the support plate 32 to move by moving the lifting rod 42 upward, thereby stretching the seal. According to the initial position and end position of the pointer 35, the corresponding force value of the force meter 3 is manually calculated, and the elongation at break and the strength at this time are used to quickly determine whether the seal meets the requirements.
[0025] The seal can be tested by simply clamping and fixing, and pressing the drive rod 41. The operation is simple and convenient, and the time required to send the finished product to the laboratory is saved, thereby shortening the production cycle and improving production efficiency. If the test results show that the seal does not meet the requirements, the producer can take immediate measures, such as adjusting the vulcanization time or changing the formula, to avoid continuing to produce unqualified products and reduce material waste. Secondly, the tooling design is flexible and can be adjusted according to different seal sizes and shapes, with strong adaptability.
[0026] Working principle: When the seal is prepared, it can be fixed on the upper and lower clamps 5 after proper cooling, and then the locking nut 51 is twisted. The rotation of the locking nut 51 can make the openings of the upper and lower clamps 5 smaller, so that it can clamp the seal, and then loosen the limit adjustment nut 31 to adjust the height of the support plate 33 so that the seal is in an extended state, and then tighten the limit adjustment nut 31, and finally press the drive rod 41 to drive the support plate 32 to move by moving the lifting rod 42 upward, thereby stretching the seal, and manually calculate the elongation at break and the strength at this time according to the initial position and end position of the pointer 35 and the corresponding force value, so as to quickly determine whether the seal meets the requirements.
