Description

Technical Field

[0001] The utility model belongs to the field of auxiliary tools for foam core material production, and in particular relates to a foam core material tensile test bonding and positioning tool. Background Art

[0002] Foam core material is a material made of polymer foaming. It has low density and light weight, but high strength and good toughness. It has good heat insulation, sound insulation, shock absorption and other properties. It is widely used in construction, aerospace, automobile manufacturing, electronic products and other fields, playing a role in protection, cushioning, sound absorption and so on.

[0003] The foam core tensile test is a method to test the mechanical properties of foam materials. This test is usually performed using a tensile testing machine. The principle is to apply a continuous tensile force along the longitudinal direction of the material to measure the stress and strain of the material. When performing a tensile test on a foam material, the sample needs to be cut into the corresponding shape and size first. Then, the sample is clamped into the fixture of the tensile testing machine and a gradually increasing tensile force is applied until the sample breaks. During the stretching process, sensors can be used to measure the stress and strain of the material and record the tensile curve. By analyzing the tensile curve, many useful mechanical parameters can be obtained, such as maximum tensile force, elongation at break, elastic modulus, shear modulus, etc. These parameters can be used to evaluate the mechanical properties of foam materials to determine whether they are suitable for specific application scenarios. In short, the foam material tensile test is a commonly used test method that can help researchers understand the mechanical properties of foam materials and provide an important reference for engineering design and product development.

[0004] The method of clamping the foam core material on the tensile testing machine is: first, a tensile fixture is bonded to each end of the foam core material, and then the tensile fixtures at both ends are fixed to the tensile testing machine fixture. However, when the foam core material and the tensile fixture are bonded, they are often misaligned, and the top, bottom, left, and right sides are not aligned, resulting in inaccurate tensile test results. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem that the foam core material is often directly manually bonded to the stretching tooling before the tensile test, which may cause the foam core material sample and the stretching tooling to be misaligned, resulting in inaccurate tensile test results.

[0006] In order to solve the above technical problems, the utility model provides a foam core material tensile test bonding positioning tool, comprising a bottom plate, at least two side positioning components arranged at intervals, a tail end positioning piece, a head pushing positioning piece and a pushing support plate, wherein the pushing support plate and the tail end positioning piece are respectively fixed to the front and rear ends of the bottom plate;

[0007] Each of the side positioning assemblies comprises a left limiting plate and a right limiting plate which are relatively arranged on the bottom plate;

[0008] The tail end positioning member includes a large width diameter groove and a small width diameter groove, the large width diameter groove and the small width diameter groove are connected front and back, the width diameter value of the large width diameter groove is equal to the length value of the bonding plate of the stretching tooling, and is greater than the width diameter value of the small width diameter groove, and the width diameter value of the small width diameter groove is greater than or equal to the thickness value of the fixing part of the stretching tooling;

[0009] The push support plate is provided with a through hole and a guide tube, one end of the guide tube is fixed to the front side or the rear side of the push support plate, and the inner diameter of the guide tube is the same as the diameter of the through hole;

[0010] The head pushing positioning member includes a three-sided enclosing frame and a sliding rod. The three-sided enclosing frame contains a receiving groove for accommodating the fixing part of the stretching tooling. One side of the three-sided enclosing frame is provided with an accommodating groove opening. The end of the three-sided enclosing frame facing away from the opening is fixed to one end of the sliding rod. The sliding rod penetrates into the guide tube and can slide in the guide tube. The inner diameter of the guide tube is equal to the diameter of the sliding rod.

[0011] Preferably, the tail end positioning member includes a front plate, a left plate and a right plate, one end of the left plate and one end of the right plate are respectively fixed to the two ends of the front plate, the left plate and the right plate are arranged in parallel and perpendicular to the front plate, and the left plate and the right plate enclose the large width diameter groove and the small width diameter groove.

[0012] Preferably, the left plate and the right plate constitute one of the side positioning components.

[0013] Preferably, the pushing support plate includes a main board and two reinforcement plates, the rear ends of the two reinforcement plates are fixed to the rear side of the main board, and the bottom sides of the main board and the reinforcement plates are fixed to the bottom plate.

[0014] Preferably, the left limiting plate and the right limiting plate are integrally connected to the bottom plate and are bent relative to the bottom plate.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] The utility model provides a foam core material tensile test bonding positioning tool, comprising a bottom plate 1, at least two side positioning components 2 arranged at intervals, a tail end positioning member 3, a head pushing positioning member 4 and a pushing support plate 5, wherein the pushing support plate 5 and the tail end positioning member 3 are respectively fixed to the front and rear ends of the bottom plate 1;

[0027] When the foam core material sample 7 of the utility model is subjected to a tensile test, a tensile tool 6 needs to be attached to each of the two ends. The two tensile tool 6 are then fixed to the tensile equipment respectively.

[0028] Among them, the bottom plate 1 plays the role of fixing the tail end positioning member 3, the side positioning component 2 and the pushing support plate 5, and also makes the foam core material sample 7 and the stretching tooling 6 on the same horizontal plane.

[0029] The push support plate 5 provides a guide for the head push positioning member 4 to move in the front-to-back direction. The tail end positioning member 3 can determine the direction of the stretching tooling 6 and the foam core material sample 7 that need to be pasted on the tail end of the foam core material sample 7 and limit the front-to-back direction, while the head push positioning member 4 can position and push the stretching tooling 6 that needs to be pasted on the front end of the foam core material sample 7, and push the stretching tooling 6 to be pasted on the front end of the foam core material sample 7. The tail end positioning member 3 of the utility model also plays the role of the side positioning component 2, and its left plate 34 and right plate 35 constitute a side positioning component 2, which together with another side positioning component 2 limits the left and right directions of the foam core material sample 7 to prevent the front-to-back misalignment of the foam core material sample 7 and the stretching tooling 6 when pasting.

[0030] Specifically, each side positioning assembly 2 includes a left limiting plate 21 and a right limiting plate 22 which are relatively arranged on the bottom plate 1, and respectively limit the left side and the right side of the foam core material sample 7;

[0031] The tail end positioning member 3 includes a large width diameter groove 31 and a small width diameter groove 32, and the large width diameter groove 31 and the small width diameter groove 32 are connected front and back, and the width diameter value of the large width diameter groove 32 is equal to the length value of the adhesive plate 61 of the stretching tooling 6, which is greater than the width diameter value of the small width diameter groove 32, and the width diameter value of the small width diameter groove 32 is greater than or equal to the thickness value of the fixing portion 62 of the stretching tooling 6; after the adhesive plate 61 of the stretching tooling 6 abuts against the rear wall of the large width diameter groove 31, it cannot move backwards any further, thereby limiting the stretching tooling 6 backwards, and the left and right ends of the adhesive plate 61 also abut against the left and right walls of the large width diameter groove 31 and cannot move left and right, thereby limiting the stretching tooling 6 in the left and right directions, and the fixing portion 62 is accommodated in the small width diameter groove 32. The tail end positioning member 3 specifically includes a front plate 33, a left plate 34 and a right plate 35. One end of the left plate 34 and one end of the right plate 35 are respectively fixed to the two ends of the front plate 33. The left plate 34 and the right plate 35 are arranged in parallel and perpendicular to the front plate 33. The left plate 34 and the right plate 35 enclose a large wide diameter groove 31 and a small wide diameter groove 32. The left plate 34 and the right plate 35 can also limit the left and right directions of the foam core material sample 7.

[0032] The push support plate 5 is provided with a through hole 51 and a guide tube 52. One end of the guide tube 52 is fixed to the front side or the rear side of the push support plate 5. The inner diameter of the guide tube 52 is the same as the diameter of the through hole 51.

[0033] The head push positioning member 4 includes a three-sided enclosing frame 41 and a slide bar 42. The three-sided enclosing frame 41 contains a receiving groove 411 for receiving the fixing portion 62 of the stretching tool 6. One side of the three-sided enclosing frame 41 is provided with an opening of the receiving groove 411. One end of the three-sided enclosing frame 41 away from the opening is fixed to one end of the slide bar 42. The slide bar 42 penetrates into the guide tube 52 and can slide in the guide tube 52. The inner diameter of the guide tube 52 is equal to the diameter of the slide bar 42. The function of the slide bar 42 is to facilitate manual pushing. The guide tube 52 provides guidance for the movement of the slide bar 42.

[0034] The method of using the utility model is as follows: when bonding the foam core material sample 7, first apply glue to both ends of the foam core material sample 7 respectively, then place the two stretching toolings 6 in the tail end positioning piece 3 and the head pushing positioning piece 4 (accommodating groove 411) respectively, and then place the foam core material sample 7 on the bottom plate 1 from top to bottom, with one end located in the tail end positioning piece 3 and the other end located in the side positioning component 2, but the two ends are temporarily separated from the two stretching toolings 6, and by pushing the sliding rod 42 backward, the three-sided enclosing frame 41 moves backward and drives the stretching toolings 6 therein to move backward at the same time, until the stretching toolings 6 in the three-sided enclosing frame 41 touches the front end of the foam core material sample 7, and also drives the foam core material sample 7 to move backward together, and finally the rear end of the foam core material sample 7 touches the stretching toolings 6 of the tail end positioning piece 3, and the three are pressed together by the head pushing positioning piece 4, so that the two stretching toolings 6 are respectively bonded to the two ends of the foam core material sample 7.

[0035] In order to make the utility model applicable to new foam material samples of different lengths, the tail end positioning member 3 can be adjusted and fixed in the length direction of the bottom plate 1, so as to adjust the distance from the push support plate 5. To this end, the tail end positioning member 3 also includes a detachable connecting plate 36, which is horizontally arranged and has a connecting hole 361. The bottom plate 1 is located at the rear half and is provided with a plurality of groups of mounting holes 11 with different distances from the push support plate 5. All groups of mounting holes 11 are connected to the connecting hole 361 one by one.

[0036] In order to improve the stability of the push support plate 5 on the bottom plate 1, the push support plate 5 includes a main plate 53 and two reinforcement plates 54. The rear ends of the two reinforcement plates 54 are fixed to the rear side of the main plate 53, and the bottom sides of the main plate 53 and the reinforcement plates 54 are fixed to the bottom plate 1. The left limit plate 21 and the right limit plate 22 are integrally formed and connected to the bottom plate 1, and are bent compared to the bottom plate 1. Compared with the form of fixing the left limit plate 21 and the right limit plate 22 on the bottom plate 1 with screws, it is more convenient and saves materials.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
