Description

Technical Field

[0001] This utility model relates to the field of adhesive resin testing technology, and in particular to an adhesive resin strength testing mechanism. Background Technology

[0002] Steel wire pipe is an industrial pipe product made of high-strength steel wire as the skeleton reinforcement and high-density polyethylene (HDPE) or polyvinyl chloride (PVC) through adhesive resin.

[0003] Adhesive resin plays a crucial role in steel wire hoses (especially steel wire reinforced rubber hoses). It is the key material to ensure a strong and durable chemical bond between the rubber matrix and the high-strength steel wire reinforcement layer. The steel wire coated with adhesive resin is braided or wound onto the extruded inner rubber hose blank according to the design requirements, and then covered with the outer rubber layer and vulcanized to achieve the bonding of the steel wire.

[0004] As for the bonding strength of adhesive resin, it is usually necessary to use a testing agency to test its bonding strength. Currently, the testing agency cuts a sample from the finished steel wire pipe or the vulcanized pipe blank and then performs a peel test on the sample. This testing method can usually only test one sample at a time. When multiple samples need to be tested, testing them sequentially can easily affect the testing efficiency. Therefore, a bonding resin strength testing agency is proposed to solve the above problems. Utility Model Content

[0033] like Figures 1-5As shown, the present invention proposes an adhesive resin strength testing mechanism, which includes a testing platform 1, a set of movable plates 2 slidably connected on the testing platform 1, and a set of fixed plates 4 fixedly connected on the testing platform 1, with the set of movable plates 2 located between the set of fixed plates 4.

[0034] The movable plate 2 is equipped with a fastener 3 for fixing the tensile test.

[0035] The upper surface of the fixing plate 4 is provided with clamping parts 5 for placing and fixing the sample;

[0036] The lower surface of the testing table 1 is provided with a driving component 6 for driving the movable plate 2 to move laterally.

[0037] In this invention, the fastener 3 on the movable plate 2, in conjunction with the clamping member 5 on the fixed plate 4, facilitates the simultaneous testing of multiple samples.

[0038] In an optional embodiment, the fixing member 3 includes a plurality of placement blocks 37. The upper surface of each movable plate 2 is provided with a plurality of grooves 34, and the plurality of placement blocks 37 are slidably connected in each groove 34. A pressure block 35 located above the placement block 37 is slidably connected in each groove 34. A connecting block 38 is fixedly connected to the upper surface of each placement block 37 at the end away from the pressure block 35. A plurality of pressure sensors 39 are fixedly installed on the upper surface of each movable plate 2, and the number of pressure sensors 39 corresponds to the number of grooves 34, and the orientation of the pressure sensors 39 corresponds to the orientation of the connecting block 38.

[0039] In this embodiment, multiple test samples can be clamped simultaneously by a number of fixing blocks 52 and placement slots 51, and the steel wires in multiple steel wire tube test samples can be stretched by the placement block 37 and the pressure block 35. Then, the steel wires in multiple test samples are individually tested by the pressure sensor 39 through the corresponding connecting block 38 to peel off the force required for each test, without having to test multiple test samples one by one, thereby improving testing efficiency.

[0040] It should be noted that the movable plate 2 is provided with a pushing assembly for pushing the pressure block 35 to squeeze; the pushing assembly includes an adjusting plate 31 slidably connected to the movable plate 2, an adjusting screw 32 with one end penetrating through the adjusting plate 31 is rotatably connected to the side of the movable plate 2 away from the abutment block 36, a crossbar 33 with one end penetrating through the adjusting plate 31 is fixedly connected to the side of the movable plate 2 away from the pressure block 35, and several abutment blocks 36 are fixedly connected to the upper end of the adjusting plate 31, and the positions of the several abutment blocks 36 correspond to the positions of the pressure block 35, so that when the rotating adjusting screw 32 drives the adjusting plate 31 to move towards the side closer to the movable plate 2, it can drive the abutment blocks 36 on the adjusting plate 31 to squeeze the pressure block 35, and the guide blocks 310 on the front and rear sides of each abutment block 36 can support and guide the abutment block 36 to improve the stability of the abutment block 36 during the movement;

[0041] The front and rear sides of the placement block 37 and the pressure block 35 are provided with elastic support members for elastically supporting the pressure block 35; the elastic support members include support blocks 311 fixedly connected to the front and rear sides of each placement block 37 and the pressure block 35, and a spring 313 is fixedly connected between the bottom support block 311 and the top support block 311. A vertical rod 312 with one end penetrating through the top support block 311 is fixedly connected to the bottom support block 311. The front and rear sides of each groove 34 are convex, and the convex end of the groove 34 is used to accommodate the support block 311. The bottom support blocks 311 on the front and rear sides of each placement block 37, together with the vertical rod 312 and the spring 313, can elastically support each pressure block 35 and the top support blocks 311 on the front and rear sides of the pressure block 35.

[0042] The lower surface of the pressure block 35 and the upper surface of the placement block 37 are both serrated, which increases the friction between the pressure block 35 and the placement block 37 when clamping the end of the steel wire, thereby improving the clamping stability when stretching the steel wire. The upper surface of the movable plate 2 has several rectangular holes, which correspond to the groove 34 and are interconnected. The pressure sensor 39 is installed in the rectangular holes, and the upper end of the connecting block 38 extends into the rectangular holes and fits against the force-bearing end of the pressure sensor 39. When the pressure block 35 and the placement block 37 clamping the end of the steel wire stretch and peel the steel wire, the placement block 37 can drive the connecting block 38 to bear the force together and squeeze the pressure sensor 39, so that the pressure sensor 39 bears the force.

[0043] In an optional embodiment, the clamping member 5 includes a plurality of fixing blocks 52, and the upper surface of the fixing plate 4 is provided with a plurality of placement grooves 51, and the plurality of fixing blocks 52 are slidably connected in a corresponding manner within the plurality of placement grooves 51. A long strip block 54 is fixedly connected to the plurality of fixing blocks 52, and a rotating screw 55 with one end penetrating through the long strip block 54 is rotatably connected to the middle of the upper surface of the fixing plate 4.

[0044] In this embodiment, when the rotating screw 55 drives the long strip block 54 to move towards the side closer to the fixed plate 4 for adjustment, the long strip block 54 can drive several fixed blocks 52 to move into the placement groove 51, so as to drive the fixed blocks 52 to squeeze and fix the steel wire tube sample placed in the placement groove 51.

[0045] It should be noted that each placement slot 51 is fixedly connected to a limiting rod 53 that passes through each fixing block 52. The limiting rod 53 limits the fixing block 52, making the fixing block 52 more stable during adjustment. The long strip block 54 has a second threaded hole in the middle, and the second threaded hole is adapted to the thread on the outside of the rotating screw 55, so that the rotating screw 55 can drive the long strip block 54 to move in a vertical and horizontal direction, thereby driving several fixing blocks 52 to move and adjust synchronously. The lower surface of the fixing block 52 and the inner bottom wall of the placement slot 51 are both serrated to improve the stability of the sample clamping when the fixing block 52 moves into the placement slot 51.

[0046] In an optional embodiment, the driving component 6 includes a dual-axis cylinder 61 fixedly connected to the middle of the lower surface of the testing platform 1. Both output ends of the dual-axis cylinder 61 are fixedly connected to a driving block 62 with one end penetrating through the testing platform 1. One end of the two driving blocks 62 penetrating through the testing platform 1 is fixedly connected to two movable plates 2 respectively. The testing platform 1 is provided with a through hole 63 for the driving block 62 to move laterally.

[0047] In this embodiment, when the activated dual-axis cylinder 61 moves and adjusts the drive blocks 62 on both sides toward opposite sides, it can drive several pressure blocks 35 and placement blocks 37 on the movable plates 2 on both sides to stretch and peel the steel wire in the steel wire tube.

[0048] The working principle in the above embodiments is as follows:

[0049] After cutting the steel wire tube to be tested into a sample of appropriate size, peel off the inner and outer layers of one end of the sample to expose the steel wire in the middle. After pulling out the end of the steel wire, the sample to be tested can be placed in the placement groove 51. Then, rotate the screw 55 to move the long block 54 towards the side closer to the fixed plate 4. During adjustment, the long block 54 can drive several fixed blocks 52 to move into the placement groove 51, so that the fixed blocks 52 can squeeze and fix the steel wire tube sample placed in the placement groove 51, so that the exposed end of the steel wire in the sample faces the movable plate 2.

[0050] Then, the dual-axis cylinder 61 is activated, which pushes the movable plates 2 on both sides towards the side closer to the fixed plate 4 through the drive block 62. This drives the pressure block 35 and the placement block 37 on the movable plate 2 to fit against the fixed plate 4. Then, the adjusting screw 32 is rotated to move the adjusting plate 31 towards the side closer to the movable plate 2. This then drives the abutment block 36 on the adjusting plate 31 to press the pressure block 35, causing the pressure block 35 to move towards the side of the placement block 37. After this adjustment, the exposed end of the steel wire in the sample can be clamped and fixed. Then, the dual-axis cylinder 61 is reset, which pulls the drive blocks 62 on both sides to move the movable plate 2 towards the opposite side. By fixing the end of the steel wire, the steel wire is stretched and peeled out of the sample.

[0051] During the tensile peeling process, the force exerted by the placing block 37 on the steel wire can be applied to the pressure sensor 39 through the connecting block 38, so that the pressure sensor 39 can detect the force required for the fiberglass wire to complete the glass detection of the steel wire in multiple steel wire tube samples, thereby detecting the adhesive force of the bonding resin.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
