Description

Technical Field

[0001] The utility model relates to the technical field of metallographic analysis, in particular to a metallographic pattern mold and a manufacturing system. Background Art

[0002] When measuring the cross-sectional state of an object, it is usually necessary to make a metallographic pattern. A metallographic pattern is also called a metallographic cold mount. It is a sample formed by wrapping and fixing the object to be observed with a curing agent. Currently in the battery field, when making a metallographic pattern, the object to be observed is usually placed vertically in the center of the mold by gravity, double-sided tape, or handheld. Then the curing agent is poured in, and after curing, it is taken out and polished for observation and measurement.

[0003] In the field of lithium-ion cylindrical batteries, the material ratio of the tabs, the wall thickness of the steel shell and the shape after grooving, the size of the cap after sealing, etc. need to be tested or measured by making metallographic samples. However, for objects to be observed that are thin, small or irregular in shape, such as tabs, the above-mentioned fixing method is inconvenient to operate and the fixing is unstable. During the curing process of the curing agent, the objects to be observed are prone to tilt, affecting the quality of the metallographic sample and further affecting subsequent testing or measurement.

[0007] The metallographic pattern mold provided by the utility model is used for making metallographic patterns. By arranging a first fixing groove on the mold body, the object to be observed can be clamped more conveniently. A cover body is arranged at the opening of the mold body, and a second fixing groove is arranged on the cover body, so that the object to be observed can be clamped from both sides, so that the object to be observed can be firmly clamped and fixed, thereby avoiding the object to be observed from being deflected during the process of liquid injection and solidification, thereby preventing the quality of the metallographic pattern from being affected.

[0017] and / or,

[0018] The first fixing groove is a closed groove, and the second fixing groove is a through groove.

[0019] The first fixing groove and the second fixing groove arranged opposite to each other can clamp most objects to be observed and have a wide application range.

[0020] The first fixed groove is a closed groove that can prevent liquid from flowing out from the bottom of the mold body, and the second fixed groove is a through groove that allows the object to be observed to extend out of the cover body without the need for precise cutting of the length of the object to be observed, which can simplify the operation process and improve efficiency.

[0021] As a preferred solution of the utility model, a step portion is formed at the opening of the mold body along its circumference, and the cover body can overlap the step portion.

[0023] As a preferred solution of the present invention, the mold body and the cover body are both made of rubber material.

[0024] The rubber material facilitates demoulding and the opening of the first fixing groove and the second fixing groove.

[0025] A metallographic pattern making system comprises an object to be observed and the metallographic pattern mold as described above, wherein: a cover body covers the opening of the mold body, and the object to be observed is clamped in a first fixing groove and a second fixing groove.

[0026] The metallographic pattern making system provided by the utility model can simplify the clamping operation of the object to be observed by clamping the object to be observed on the first fixing groove and the second fixing groove, and make the object to be observed more firmly fixed, so as to avoid the object from being deflected during the process of liquid injection and solidification, which affects the quality of the metallographic pattern.

[0027] The cover body is closed on the opening of the mold body, and the curing agent can be poured into the cover body from the injection hole or injection groove, so that it is more intuitive to observe whether the injection is completed, and the amount of liquid protruding from the upper edge of the mold body due to the surface tension of the liquid when it is filled is reduced, which is conducive to reducing the waste of curing agent and reducing the frequency of cleaning.

[0028] As a preferred solution of the utility model, the object to be observed is a pole ear, a steel shell or a cap.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0045] Example 1

[0046] See also Figure 1-5 The present embodiment provides a metallographic pattern mold, comprising a mold body 1 with an accommodating cavity 9, the mold body 1 is provided with an opening connected to the accommodating cavity 9, and a cover body 2 is matched at the opening; a first fixing groove 3 is provided at the inner bottom of the mold body 1, and a second fixing groove 4 is provided on the cover body 2, and the first fixing groove 3 and the second fixing groove 4 can both clamp the object to be observed; and also includes an injection channel, which connects the accommodating cavity 9 and the outside of the mold body 1.

[0047] The mold body 1 can be a cylinder, a cube, a sphere, etc. The mold body 1 has a receiving cavity 9 for receiving a curing agent and an object to be observed.

[0048] The cover body 2 covers the opening on the mold body 1 that is connected to the accommodating cavity 9. If there are multiple openings, the cover body 2 covers the main opening, which refers to the opening that can accommodate the object to be observed.

[0049] The cover 2 can overlap on the opening without falling off.

[0050] The inner bottom of the mold body 1 refers to the inner wall of the mold body 1 opposite to the opening.

[0051] The first fixing groove 3 and the second fixing groove 4 are groove-shaped structures, having a lower groove body relative to the surrounding surface. The lower groove body can be made of a material with good elasticity such as rubber and plastic. When the object to be observed is inserted into the lower groove body and its side walls are squeezed open, the side walls of the lower groove body can rebound to clamp the object to be observed.

[0052] If the object to be observed has good elasticity, the lower groove body can also be made of steel, wood or other materials with normal resilience. When the object to be observed is inserted into the lower groove body, it itself will deform and rebound to get stuck in the lower groove body.

[0053] The side walls of the lower groove body can be fitted together or spaced apart, and the cross-sectional shape of the lower groove body can be linear, cross-shaped, T-shaped, rectangular, circular, etc.

[0054] The liquid injection channel is arranged on the mold body 1 or the cover body 2 , and is used to transport liquid into the accommodating cavity 9 .

[0055] The metallographic pattern mold provided by the utility model is used for metallographic pattern production. By arranging a first fixing groove 3 on the mold body 1, the object to be observed can be clamped more conveniently. A cover body 2 is arranged at the opening of the mold body 1, and a second fixing groove 4 is arranged on the cover body 2. The object to be observed can be clamped from both sides, so that the object to be observed can be firmly clamped and fixed, thereby preventing the object to be observed from being deflected during the process of liquid injection and solidification, thereby preventing the quality of the metallographic pattern from being affected.

[0056] The metallographic pattern mold provided by the utility model is simple to manufacture, convenient to use, and has good clamping and fixing performance, and can manufacture metallographic patterns with uniform specifications and excellent quality.

[0057] Preferably, a liquid injection hole 5 or a liquid injection groove is provided on the cover body 2 , and the liquid injection hole 5 or the liquid injection groove is located above the accommodating cavity 9 .

[0058] The injection hole 5 is a hole-like structure arranged within the edge of the cover body 2, and the injection groove is a groove-like notch arranged on the edge of the cover body 2. When the cover body 2 is covered on the mold body 1, the injection hole 5 and the injection groove can form an injection channel connecting the accommodating cavity 9 and the outside.

[0059] During the liquid injection operation, it is often necessary to fill the accommodating chamber 9 to form a complete metallographic sample, so the liquid injection hole 5 or the liquid injection groove is arranged above the accommodating chamber 9 .

[0060] Due to the tension on the liquid surface, when the accommodating cavity 9 is filled, the liquid level in the middle will be higher than the upper edge of the mold body 1. At this time, a slight vibration can cause the liquid to overflow, resulting in waste of curing agent and troublesome cleaning. For this reason, a cover body 2 is added to the mold body 1, and an injection hole 5 or an injection groove is provided on the cover body 2, which can reduce the overflow of liquid during injection.

[0061] The diameter of the injection hole 5 or the injection groove is relatively small, and its side wall can form a relatively obvious dividing line, through which it can be more intuitively observed whether the injection is completed, and the overflowing liquid can be received by the cover body 2, which can reduce the frequency of table cleaning.

[0062] Example 2

[0063] See also Figure 1-5 The metallographic pattern mold provided in this embodiment is further optimized and designed based on the embodiment 1. Specifically, in this embodiment, the first fixing groove 3 and the second fixing groove 4 are both cross grooves.

[0064] A cross groove refers to a groove type with a cross-section similar to that of a "cross". The cross groove has two intersecting grooves, each of which has two side walls that are fitted or close to each other. The object to be observed can extend between the side walls and apply an extrusion force to the side walls. Under the extrusion of the reaction force, the object to be observed can be clamped by the side walls.

[0065] The cross slot is easy to open and can clamp most objects to be observed, and has a wide range of applications.

[0066] Preferably, a fool-proof structure is provided between the mold body 1 and the cover body 2. The fool-proof structure can align the cross directions of the first fixing groove 3 and the second fixing groove 4 or form a specific angle, so as to facilitate the installation of the object to be observed.

[0067] There are many ways to set up the foolproof structure, which can be a protrusion that bites into a groove, or a column that is inserted into a hole.

[0068] In this embodiment, a fool-proof protrusion 6 is provided on the cover body 2, and a fool-proof notch 7 is provided on the mold body 1, and the fool-proof protrusion 6 is matched with the fool-proof notch 7.

[0069] like Figure 1-2As shown, the fool-proof protrusion 6 is arranged along the radial direction of the cover body 2, and the fool-proof notch 7 is located at the upper edge of the mold body 1. The fool-proof protrusion 6 can be placed in the fool-proof notch 7 to align the first fixing groove 3 and the second fixing groove 4.

[0070] Example 3

[0071] See also Figure 1-5 The metallographic pattern mold provided in this embodiment is further optimized and designed based on the embodiment 1 or 2. Specifically, in this embodiment, the first fixing groove 3 and the second fixing groove 4 are arranged opposite to each other.

[0072] The relative setting means that the axes of the lower groove bodies of the first fixed groove 3 and the second fixed groove 4 are roughly located in a straight line. The relative setting can better clamp straight components and arc-shaped components with a small curvature. Considering that the size of the clamp body is relatively small, the relative setting can clamp most objects to be observed and has a wide range of applications.

[0073] In this embodiment, the first fixing groove 3 is a closed groove, and the second fixing groove 4 is a through groove.

[0074] The closed groove has an open end and a closed end. The open end of the first fixed groove 3 is arranged on a side close to the accommodating cavity 9 of the mold body 1. Setting the first fixed groove 3 as a closed groove can prevent the curing agent from flowing out from the other end.

[0075] The through groove has two open ends, and the two open ends of the through groove are connected. The second fixed groove 4 is set as a through groove, so that the object to be observed can extend out of the second fixed groove 4. When making a sample of the object to be observed, it is not necessary to accurately control the length of the sample. It is only necessary to meet a certain minimum length so that the object to be observed can be clamped more firmly on the first fixed groove 3 and the second fixed groove 4, which can simplify the operation process and improve efficiency.

[0076] Example 4

[0077] The metallographic pattern mold provided in this embodiment is further optimized and designed based on the embodiment 1, 2 or 3. Specifically, in this embodiment, the mold body 1 is cylindrical and the cross-sectional shape of the cover body 2 is also circular.

[0078] In this embodiment, a step portion 8 is formed along the circumference of the opening of the mold body 1, and the cover body 2 can overlap the step portion 8, see Figure 1-5 .

[0079] The step portion 8 is a step-like overlapping platform structure arranged at the upper edge of the mold body 1. The step portion 8 has an annular overlapping plane arranged along the circumference of the mold body 1. The size of the cover body 2 is located between the inner ring size and the outer ring size of the annular overlapping plane, so that the cover body 2 can be placed on the annular overlapping plane, which is convenient for the closing of the cover body 2 and can prevent the cover body 2 from falling into the mold body 1 and causing the failure of the metallographic pattern production.

[0080] In this embodiment, the mold body 1 and the cover body 2 are both made of rubber material.

[0081] The rubber material has good resilience and deformation properties, which facilitates demoulding of the metallographic pattern and the opening of the first fixing groove 3 and the second fixing groove 4 .

[0082] Example 5

[0083] A metallographic pattern making system provided in this embodiment includes an object to be observed and a metallographic pattern mold described in Embodiment 1, 2, 3 or 4, wherein: a cover body 2 covers the opening of the mold body 1, and the object to be observed is clamped in the first fixing groove 3 and the second fixing groove 4.

[0084] Preferably, the object to be observed may be a tab, a steel shell, a cap, etc.

[0085] The object to be observed may extend out of the second fixing slot 4 or may not extend out of the second fixing slot 4.

[0086] When in use, the object to be observed can be first inserted into the second fixed groove 4, the cover body 2 is moved to drive the object to be observed to move, the cover body 2 is closed on the opening of the mold body 1, the end of the object to be observed is inserted into the first fixed groove 3, and the curing agent is injected into the mold body 1 through the injection hole 5 or the injection groove. When the curing agent is about to overflow, the injection is stopped, and it can be demoulded and taken out after waiting for solidification.

[0087] The curing agent can be a mixed liquid of acrylic powder and acrylic resin.

[0088] The curing agent is not limited to liquid, but can also be in powder form, such as metallographic embedding powder.

[0089] The metallographic pattern making system provided by the utility model can simplify the clamping operation of the object to be observed and make the fixation of the object to be observed more stable by clamping the object to be observed on the first fixing groove 3 and the second fixing groove 4, thereby avoiding the object to be observed from being skewed during the process of liquid injection and curing to affect the quality of the metallographic pattern; the cover body 2 is covered on the opening of the mold body 1, and the curing agent can be poured into the liquid injection hole 5 or the liquid injection groove on the cover body 2, so that it can be more intuitive to observe whether the liquid injection is completed, and at the same time, the amount of liquid protruding from the upper edge of the mold body 1 due to the surface tension of the liquid when it is full can be reduced, which is conducive to reducing the waste of curing agent and reducing the frequency of cleaning.
