Description

Technical Field

[0001] The utility model belongs to the technical field of metal sample preparation, and particularly relates to a rapid sample hot inlay preparation device with energy saving and water saving. Background Art

[0002] Hot inlay is generally used for the preparation of samples in the process of metallographic analysis. The preparation process is to inlay the resin and the sample into a sample with a regular shape and fixed size by heating and pressing. The hot inlay equipment first melts the resin powder by heating, and then compresses the resin powder and the metal sample together by pressing. After cooling, a sample with a regular shape is obtained, providing a standardized sample preparation for subsequent grinding and polishing.

[0003] The hot inlay process is to first raise the inlay table, place the dry and clean specimen on the inlay cylinder of the hot inlay machine, then lower the inlay table, add resin powder to the inlay cylinder, tighten the sealing cover, and wait for the heating - heat preservation - cooling process to be completed in the inlay cylinder to obtain the inlaid specimen. The existing inlay machines can only prepare one sample at a time. Moreover, when heating or cooling metal samples, although the specimen only occupies a very small part of the height of the cylinder, the heating or cooling acts on the entire cylinder. The non - differentiated heating method will cause great energy waste; in order to improve the efficiency of hot inlay preparation and save energy, it is necessary to improve the existing equipment. Summary of the Utility Model

[0004] In view of the above problems and technical requirements, the utility model provides a rapid sample hot inlay preparation device with energy saving and water saving. This device can inlay multiple samples at one time, and can accurately control the temperature, only heating or cooling the area where the sample is located, avoiding energy waste.

[0005] The technical solution of the utility model is as follows: a rapid sample hot inlay preparation device with energy saving and water saving, including an inlay table, an inlay sleeve and a locking mechanism. The inlay table is provided with an inlay sleeve. The inlay sleeve includes an inner sleeve and an outer sleeve arranged coaxially. The inner sleeve is slidably connected to the core of the outer sleeve. The inner sleeve is a sample processing cavity. The outer sleeve is provided with a heating layer and a cooling layer. The heating layer can heat the inner sleeve in sections along the axis, and the cooling layer can cool the inner sleeve in sections along the axis; a jacking device is arranged in the inlay table, and the jacking device can jack up from the inlay table into the inner sleeve to perform pressing processing on the sample in the inner sleeve. Multiple samples can be inlaid in the inner sleeve at the same time; the locking mechanism is detachably arranged at the upper end of the inlay sleeve, and the locking mechanism seals the upper port of the inner sleeve tightly.

[0006] Furthermore, the lower end of the inner sleeve is flush with the lower end face of the outer sleeve, and the upper end of the inner sleeve protrudes from the upper end face of the outer sleeve. The locking mechanism is locked and sealed with the upper end of the inner sleeve. One or more pressing spacers are detachably and slidably connected in the inner sleeve. The pressing spacers divide the sample processing cavity into multiple pressing areas along the axis. Each pressing area processes one sample by inlaying. The ejecting device ejects upward from the lower end of the inner sleeve, and at the same time, presses and processes multiple samples in the sample processing cavity.

[0007] Furthermore, the outer sleeve is a hollow sleeve, and a heating layer is provided inside the outer sleeve. The heating layer is arranged against the outer side of the inner sleeve. The heating layer is axially disconnected into multiple independent heating zones. The independent heating zones can heat a section of the inner sleeve separately, or multiple independent heating zones can be turned on simultaneously to heat the inner sleeve together.

[0008] Furthermore, the outside of the heating layer is a cooling layer. The cooling layer includes multiple cooling cavities. The cooling cavities are arranged at intervals along the axis in segments. The positions of the multiple cooling cavities correspond to those of the independent heating zones one by one. A water inlet is provided on one side of each cooling cavity, and a water outlet is provided on the other side. The cooling cavities cool down the heating layer and the inner sleeve.

[0009] Furthermore, a temperature sensor is provided in each cooling cavity. One end of the temperature sensor contacts the heating layer, and the other end extends outward through the outer side surface of the outer sleeve. The temperature sensor can sense the temperature of the corresponding independent heating zone. When the temperature reaches the set temperature, the heating is stopped and the cooling operation is performed.

[0010] Furthermore, the ejecting device includes a ejecting rod and a lower plug. The ejecting rod is vertically arranged in the inlaying table. A lower plug is provided at the top of the ejecting rod. The diameter of the lower plug is the same as the inner diameter of the inner sleeve, and the lower plug is correspondingly inserted into the inner sleeve. The ejecting rod pushes the inlaying material upward from below, and the upper plug and the lower plug press the sample from the upper and lower ends respectively.

[0011] Furthermore, a limit sensor switch is installed on the lower end face of the outer sleeve. The front end of the limit sensor switch contacts the lower end of the inner sleeve. When the inner sleeve is lifted upward and separated from the limit sensor switch, the limit sensor switch is disconnected. By installing the limit sensor switch at the bottom, when the ejecting rod applies excessive pressure to the inlaying material, it will cause the inner sleeve to slide upward. At this time, the limit sensor switch will be disconnected and the device will stop working, improving the safety of the device.

[0012] Furthermore, the locking mechanism includes a cap, a locking ring and an upper plug. The upper plug is arranged inside the locking ring. The diameter of the upper plug is the same as that of the lower plug, and the upper plug is correspondingly embedded in the inner sleeve. The locking ring is blocked on the upper end face of the outer sleeve. The locking ring and the protruding inner sleeve are locked by screws. The cap is covered on the locking ring, and the cap and the locking ring are connected by a buckle. The upper plug can seal the upper port of the inner sleeve and provide top support for compressing the inlaying material.

[0013] Further, a positioning hole is provided at the top of the cap, and a pressure plate is inserted into the top of the cap. An operating handle is provided on the pressure plate. By driving the pressure plate to rotate through the operating handle, the pressure plate drives the cap to rotate clockwise or counterclockwise at the same time, so that the cap and the locking ring are clamped and fixed or the connection is released. The pressure plate can conveniently lock and remove the cap and the locking ring, ensuring the tightness of the inlay processing process.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1) The present utility model provides a detachable pressure-retaining spacer in the inner sleeve, which divides the sample processing cavity into multiple pressure-retaining areas, and each pressure-retaining area can inlay one sample. Therefore, multiple samples can be inlaid at one time, improving the inlay processing efficiency; 2) The heating of the cylinder body is optimized, and the heating corresponding to the height is automatically turned on according to the height of the inlay material in the inner sleeve, which is different from the traditional non-differential heating of the entire cylinder body. When the inlay material is melted and compressed, the heating of the area without inlay material stops, reducing the power consumption; 3) During the cooling process of the sample, only the area where the sample is located is cooled, reducing the consumption of cooling water and also avoiding the power consumption of reheating the cylinder body during the subsequent working process.

[0021] As Figures 1-4The following shows a rapid sample hot inlay preparation device for energy and water conservation of the present utility model, which includes an inlay table 6, an inlay sleeve 2 and a locking mechanism 1. The inlay sleeve 2 is installed on the inlay table 6. The inlay sleeve 2 includes an inner sleeve 3 and an outer sleeve 4 arranged coaxially. The inner sleeve 3 is slidably connected to the core of the outer sleeve 4. The inner sleeve 3 is a sample processing cavity. The outer sleeve 4 is provided with a heating layer and a cooling layer. The heating layer can heat the inner sleeve 3 in sections along the axis, and the cooling layer can cool the inner sleeve 3 in sections along the axis.

[0022] The lower end of the inner sleeve 3 is flush with the lower end face of the outer sleeve 4, and the upper end of the inner sleeve 3 protrudes from the upper end face of the outer sleeve 4. The locking mechanism 1 is locked and sealed with the upper end of the inner sleeve 3. One or more pressure material separating plates 32 are detachably and slidably connected in the inner sleeve 3. The pressure material separating plates 32 divide the sample processing cavity into multiple pressure material areas 31 along the axis. Each pressure material area 31 processes the inlay of one sample. The ejecting device ejects upward from the lower end of the inner sleeve 3, and at the same time, presses the materials of multiple samples in the sample processing cavity. The outer sleeve 4 is a hollow sleeve. A heating layer is provided on the inner side of the outer sleeve 4. The heating layer is arranged close to the outer side of the inner sleeve 3. The heating layer is axially disconnected into multiple independent heating areas 41. The independent heating areas 41 can heat a section of the inner sleeve 3 alone, or multiple independent heating areas 41 can be turned on at the same time to jointly heat the inner sleeve 3.

[0023] The cooling layer is arranged outside the heating layer. The cooling layer includes multiple cooling cavities 42. The cooling cavities 42 are arranged at intervals in sections along the axis. The positions of the multiple cooling cavities 42 and the independent heating areas 41 correspond one by one. Each cooling cavity 42 is provided with a water inlet 421 on one side and a water outlet 422 on the other side. The cooling cavities 42 cool down the heating layer and the inner sleeve 3. Each cooling cavity 42 is provided with a temperature sensor 423. One end of the temperature sensor 423 contacts the heating layer, and the other end extends outwards through the outer side surface of the outer sleeve 4. The temperature sensor 423 can sense the temperature of the corresponding independent heating area 41. When the temperature reaches the set temperature, the heating is stopped for cooling operation.

[0024] An ejecting device 5 is arranged in the inlay table 6. The ejecting device 5 can eject upward from the inlay table 6 into the inner sleeve 3 to press the materials of the samples in the inner sleeve 3. Multiple samples can be inlaid in the inner sleeve 3 at the same time. The locking mechanism 1 is detachably arranged at the upper end of the inlay sleeve 2. The locking mechanism 1 seals the upper port of the inner sleeve 3 tightly.

[0025] The locking mechanism 1 includes a cap 12, a locking ring 13 and an upper plug 14. The upper plug 14 is arranged inside the locking ring 13. The diameter of the upper plug 14 is the same as that of the lower plug 52. The upper plug 14 is correspondingly embedded in the inner sleeve 3. The locking ring 13 is blocked on the upper end face of the outer sleeve 4. The locking ring 13 and the protruding inner sleeve 3 are locked by screws. The cap 12 covers the locking ring 13. The cap 12 and the locking ring 13 are connected by a buckle 131. The upper plug 14 can seal the upper port of the inner sleeve 3 and provide top support for the compression inlay material. A positioning hole 121 is provided at the top of the cap 12. A pressure plate 11 is inserted into the top of the cap 12. An operating handle 111 is provided on the pressure plate 11. By driving the pressure plate 11 to rotate through the operating handle, the pressure plate 11 drives the cap 12 to rotate clockwise or counterclockwise at the same time, so that the cap 12 and the locking ring 13 are clamped and fixed or the connection is released. The pressure plate 11 can conveniently lock and remove the cap 12 and the locking ring 13, ensuring the tightness of the inlay processing process.

[0026] The ejecting device 5 includes an ejector rod 51 and a lower plug 52. The ejector rod 51 is vertically arranged in the inlay table 6. A lower plug 52 is provided at the top of the ejector rod 51. The diameter of the lower plug 52 is the same as the inner diameter of the inner sleeve 3. The lower plug 52 is correspondingly inserted into the inner sleeve 3. A limit sensor switch 7 is installed on the lower end face of the outer sleeve 4. The front end of the limit sensor switch 7 contacts the lower end of the inner sleeve 3. When the inner sleeve 3 is pushed up and separated from the limit sensor switch 7, the limit sensor switch 7 is disconnected. By installing the limit sensor switch 7 at the bottom, when the ejector rod 51 applies excessive pressure to the inlay material, it will cause the inner sleeve 3 to slide upward. At this time, the limit sensor switch 7 will be disconnected and the device will stop working, improving the safety of the device.

[0027] Working process of the utility model: The ejector rod 51 drives the lower plug 52 to penetrate the inner sleeve 3 from bottom to top, pushing out all the pressure-retaining spacers 32. Place the first sample on the lower plug 52. The ejector rod 51 retracts to a height sufficient to accommodate the first portion of the embedding material, fills the inner sleeve 3 with the first portion of the embedding material, then places a pressure-retaining spacer 32, and the pressure-retaining spacer 32 presses on the first portion of the embedding material. Place the second sample on the pressure-retaining spacer 32. The ejector rod 51 continues to retract to a height sufficient to accommodate the second portion of the embedding material, fills the inner sleeve 3 with the second portion of the embedding material, then places another pressure-retaining spacer 32, and the pressure-retaining spacer 32 presses on the second portion of the embedding material. According to the above method, samples and embedding materials are sequentially added in more than 2 pressure-retaining areas 31. After the addition is completed, lock the locking mechanism 1 with the upper end of the inner sleeve 3 tightly sealed. The ejector rod 51 drives the lower plug 52 to push up and pressurize the material. After reaching the predetermined pressure, it remains stationary. According to the height of the embedding material, open one or more independent heating zones 41 from top to bottom for melting the material. The temperature sensor 423 detects the real-time temperature of the independent heating zone 41. When the temperature reaches the predetermined temperature, close the independent heating zone 41 and start cooling through the corresponding cooling cavity 42. Cooling water is injected into the cooling cavity 42 from the water inlet 421 and flows out from the water outlet 422. After cooling is completed, multiple embedded samples are compressed and shaped. Open the locking mechanism 1, and the ejector rod 51 pushes out all the embedded samples and pressure-retaining spacers 32 upward.
