Description

Technical Field

[0001] This utility model relates to the field of automatic control technology, specifically to an automatic sample preparation device with constant temperature and pressure for protective slag melting. Background Technology

[0002] Mold flux is a functional material used in continuous casting to protect molten steel and improve billet quality. It plays a crucial role in continuous casting. Its melting temperature is a key indicator of its performance, significantly impacting the stability of the continuous casting process and billet quality. Accurately determining the melting temperature of mold flux provides critical process parameters for continuous casting, helping to optimize its formulation, improve billet surface quality, reduce billet defects, and ultimately increase production efficiency and product quality.

[0003] In the field of mold flux melting temperature detection, sample preparation quality is a key factor in ensuring test accuracy. Currently, the commonly used manual pressing method has the following main drawbacks: the pressure applied by the operator is difficult to control precisely, and differences in operating techniques among different testers can lead to inconsistent sample densities. This difference directly affects the accuracy of subsequent melting temperature measurements, failing to meet the requirements of high-precision detection. Therefore, a constant-pressure automatic sample preparation device for mold flux melting temperature was designed.

[0004] Therefore, it is necessary to invent an automatic sample preparation device with constant temperature and pressure for protective slag melting to solve the above problems. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The automatic sample preparation device for constant temperature and pressure of protective slag melting shown includes a base 1, with support seats 2 fixedly installed on both sides of the upper end of the base 1, two molds 3 arranged below the support seats 2, and a stamping mechanism 5 arranged between the tops of the two support seats 2.

[0028] The stamping mechanism 5 includes:

[0029] Hydraulic cylinder 51 is located directly above mold 3. A connecting seat 52 is fixedly installed at the lower output end of hydraulic cylinder 51. Multiple pressure heads 53 are provided at the bottom of connecting seat 52. The tops of multiple pressure heads 53 are connected to connecting seat 52 through mounting parts.

[0030] A pad 6 is provided between the upper surface of the base 1 and the lower surface of the mold 3. A cylinder 7 is fixedly installed at the upper end of the base 1 and on the back of the pad 6. The output end of the cylinder 7 is fixedly connected to the back of the pad 6.

[0031] In this example, base 1 serves as the foundation of the entire device, providing a stable placement platform to ensure that the device does not shift or shake during operation, and providing reliable support for the installation and operation of other components. Support base 2 not only supports the upper stamping mechanism 5 but also provides an installation position for mold 3. Hydraulic cylinder 51 provides stable and precisely controllable pressure to pressure head 53 through the telescopic movement of its lower output end. Compared to the pressure that is difficult to precisely control in manual pressing, hydraulic cylinder 51 can output constant pressure according to set parameters, ensuring consistent pressure applied to the protective slag raw material each time a sample is prepared, thereby obtaining samples with uniform density and effectively improving the accuracy of subsequent melting temperature determination results. Pad block 6 acts as a buffer and support during sample preparation. When pressure head 53 presses the raw material in mold 3, pad block 6 can disperse the pressure of base 1. Furthermore, through the telescopic movement of cylinder 7, the forward and backward movement of pad block 6 can be easily adjusted, thus achieving automatic material discharge.

[0032] Furthermore, in the above technical solution, a top seat 4 is fixedly installed on the top of the two support seats 2, and a sliding groove 24 is opened on the top of each of the two support seats 2. A slider 41 is fixedly installed at both ends of the bottom of the top seat 4. The slider 41 corresponds to the sliding groove 24 on the top of the two support seats 2 and is adapted to slide and connect.

[0033] In this example, the groove 24 on the support base 2 and the sliding connection with the bottom slider 41 of the top base 4 enable the top base 4 to move smoothly on the support base 2, ensuring the accurate positioning and operational stability of the stamping mechanism 5 during operation. Furthermore, due to the structural design of this device, the distance between the pressure head 53 and the mold 3 is small. Since the stamping mechanism 5 is mounted on the top base 4, the back-and-forth movement of the top base 4 on the top of the support base 2 synchronously drives the position movement of the pressure head 53, facilitating the filling of material into the material hole 31 of the mold 3.

[0034] Furthermore, in the above technical solution, the hydraulic cylinder 51 is fixedly installed on the top of the top seat 4, and the lower output end of the hydraulic cylinder 51 passes through the top seat 4 and is connected to the connecting seat 52. The mounting part on the top of the pressure head 53 is detachably fixedly connected to the connecting seat 52.

[0035] Furthermore, in the above technical solution, multiple corresponding through-holes 31 are provided on the two molds 3, the positions of the multiple through-holes 31 correspond to the positions of the multiple pressure heads 53, and the through-holes 31 are adapted to the pressure heads 53.

[0036] In this example, the connecting seat 52 connects the hydraulic cylinder 51 and the pressing head 53, stably transmitting the pressure output from the hydraulic cylinder 51 to the pressing head 53, ensuring reliable pressure transmission. Driven by the hydraulic cylinder 51, the pressing head 53 can simultaneously press the protective slag material in multiple material holes 31, achieving batch sample preparation and improving work efficiency. Furthermore, the mounting component on the top of the pressing head 53 is detachably fixed to the connecting seat 52, facilitating disassembly and installation when the pressing head 53 wears out or needs to be replaced with a different specification, increasing the flexibility and maintainability of the device. The material holes 31 correspond to and are compatible with the pressing head 53. During sample preparation, the protective slag material is filled through the material holes 31, and the pressing head 53 accurately presses the material in the material holes 31 when it presses down, ensuring the consistency of each sample's molding. The design of multiple material holes 31 allows for the simultaneous preparation of multiple samples in one operation, greatly improving sample preparation efficiency.

[0037] Furthermore, in the above technical solution, the lower inner side of each of the two support bases 2 is provided with a groove 21, the two molds 3 are placed in the groove 21, and the lower end of the two support bases 2, located in the groove 21, is provided with a plurality of insertion holes 22.

[0038] Furthermore, in the above technical solution, multiple pin holes 32 are provided at both ends of the two molds 3, and a set of pins 23 is provided on the lower outer wall of the two support seats 2. The front end of each set of pins 23 passes through the corresponding insertion hole 22 and is connected to the pin holes 32 at the ends of the two molds 3.

[0039] In this example, the groove 21 on the inner side of the lower end of the support base 2 facilitates the placement of the mold 3. The insertion hole 22 at the groove 21 engages with the pin holes 32 at both ends of the mold 3, and is connected by the pin 23, thus firmly fixing the mold 3 to the support base 2. This prevents displacement of the mold 3 during sample preparation, which would affect the sample quality. Furthermore, this method of installing the mold 3 within the groove 21 facilitates the later replacement of molds 3 of different specifications. Simultaneously, the limiting bracket 25 fixedly installed on the back of the support base 2 at the corresponding position of the top seat 4 limits the movement of the top seat 4, preventing excessive movement and damage to the device, further ensuring the safety and stability of the device's operation.

[0040] Furthermore, in the above technical solution, a limit frame 25 is fixedly installed on the back of the two support seats 2 and at the corresponding position of the top seat 4. The base 1 has an operation interface on the outside and a control system on the inside, and the top seat 4 has a display interface on the outside.

[0041] In this example, the external operating interface on the base 1 allows operators to easily set and control various parameters of the device, such as setting the pressure value of hydraulic cylinder 51 and the extension / retraction stroke of cylinder 7. The internal control system precisely controls the operation of each component based on the instructions input by the operator on the interface, achieving automated operation of the device, improving sample preparation efficiency and accuracy, and reducing the impact of human factors on sample quality. The external display interface on the top base 4 displays the device's operating parameters in real time, such as pressure value and sample preparation frequency, allowing operators to easily monitor the device's working status and make timely adjustments and operations.

[0042] The automatic sample preparation device for constant temperature and pressure of protective slag melting provided by this utility model works as follows:

[0043] The protective slag material is slowly poured into multiple through-holes 31 on the mold 3. Due to the small distance between the press head 53 and the mold 3, and the fact that the stamping mechanism 5 is mounted on the top seat 4, the operator can control the top seat 4 to move back and forth on the slide groove 24 on the top of the support seat 2 through the operating interface. This allows the operator to fill the material holes 31 of the mold 3 with a uniform and sufficient amount of material from different angles, ensuring that the amount of material in each material hole 31 is consistent, thus laying the foundation for obtaining samples of uniform quality in the future.

[0044] In the operating interface, the pressure value of hydraulic cylinder 51 is precisely set according to the characteristics of the protective slag sample, relevant standards, and sample preparation requirements. This drives hydraulic cylinder 51 to operate. The lower output end of hydraulic cylinder 51 gradually extends, transmitting stable and precise pressure to multiple pressure heads 53 via connecting seat 52. Under pressure, the multiple pressure heads 53 move synchronously and vertically downwards, pressing the protective slag raw material within the multiple material holes 31 on the mold 3.

[0045] After the pressure head 53 completes the pressing action on the raw material according to the set pressure value and pressing time, the control system automatically controls the output end of the hydraulic cylinder 51 to retract, driving the pressure head 53 to reset upward. Subsequently, the control system sends a command to the cylinder 7, the output end of the cylinder 7 retracts, pulling the pad 6 backward to separate it from the bottom of the lower mold 3. The pressed sample automatically falls from the material hole 31 of the mold 3 onto the upper surface of the base 1. Then, the cylinder 7 pushes the pad 6 forward, and the thrust generated by the pad 6 can push the formed sample out from between the upper surface of the base 1 and the bottom of the lower mold 3, while the pad 6 returns to its initial position, waiting for the next sample preparation operation. This automated discharge process not only improves sample preparation efficiency but also reduces sample damage or quality differences that may be caused by manual intervention.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
