Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic bimetallic cylinder, in particular to a temperature measuring system for hydraulic bimetallic cylinder preparation by melting and casting. BACKGROUND

[0002] The hydraulic bimetallic cylinder is a high-performance hydraulic core component based on dissimilar metal composite technology. For example, the hydraulic bimetallic cylinder can include a cylinder base body and a functional layer. When the hydraulic bimetallic cylinder is manufactured, a metal block can be placed in the center hole of the cylinder base body and put into a heating furnace together. The metal block is melted by a melting and casting process, and the metal melt is coated on the surface of the center hole of the cylinder base body to form the functional layer, thereby obtaining the hydraulic bimetallic cylinder. For example, a copper block is placed in the center hole of a steel base body, and a copper layer is formed on the surface of the center hole of the steel base body by a melting and casting process.

[0003] The actual temperature of the cylinder base body during the melting and casting process is an important monitoring parameter and is the most important reference for developing the melting and casting heating and cooling process. Insufficient heating or improper cooling of the cylinder base body can cause uneven organization and performance of the cylinder base body and the copper layer, and even affect the composite quality.

[0004] At present, in actual production, the monitoring of process parameters mostly relies on the temperature display panel of the heating furnace. This method is not rigorous in nature because the furnace temperature cannot represent the actual temperature of the workpiece. In order to ensure sufficient heating and uniform temperature of the cylinder base body, a long heating time is generally set, which not only causes waste of energy but also brings the risk of organization coarsening. CONTENT OF THE INVENTION

[0005] In view of the problems in the background art, the present application provides a temperature measuring system for hydraulic bimetallic cylinder preparation by melting and casting, which can accurately record the actual temperature of the cylinder base body, comprehensively reflect the temperature change of the cylinder base body, provide a reference for developing the melting and casting process, and improve the quality of the hydraulic bimetallic cylinder.

[0006] According to one aspect of the present application, a temperature measuring system for hydraulic bimetallic cylinder preparation by melting and casting is provided, which includes: a temperature measuring hole, which is provided on a cylinder base body; a thermocouple, which is assembled in the temperature measuring hole and is used for measuring the temperature of the cylinder base body; and a temperature measuring device, which is connected with the thermocouple and is used for receiving and outputting the temperature value of the cylinder base body.

[0007] In some embodiments of the present application, a plurality of temperature measuring holes are provided on the cylinder base body and are dispersedly arranged.

[0008] In some embodiments of this utility model, the temperature measuring hole includes: a first hole, located near the surface of the cylinder base; a second hole, located near the center hole of the cylinder base; a third hole, located near the center hole of the cylinder base and near the area for placing the metal block; and a fourth hole, located near the deepest internal point of the cylinder base.

[0009] In some embodiments of this utility model, there are two or more third holes.

[0010] In some embodiments of this utility model, the temperature measuring hole is a blind hole, and the temperature measuring hole extends from the outer surface of the cylinder base to the cylinder base.

[0011] In some embodiments of this utility model, the temperature measuring system further includes: a plug, the plug being installed at the open end of the temperature measuring hole, the plug having a through hole along the length of the temperature measuring hole, and the thermocouple being inserted into the through hole and extending into the depth of the temperature measuring hole.

[0012] In some embodiments of this utility model, the plug is a bolt, and the open end of the temperature measuring hole is threadedly engaged with the bolt.

[0013] In some embodiments of this utility model, the plug is provided with a through hole, one end of which communicates with the through hole and the other end extends to the outer surface of the plug. A rod for tightening and limiting the thermocouple is installed in the through hole.

[0014] In some embodiments of this utility model, the diameter of the temperature measuring hole on the side near its inner end is <3mm.

[0015] In some embodiments of this utility model, the diameter of the thermocouple is <1.6mm.

[0016] This application provides a temperature measurement system for the casting of hydraulic bimetallic cylinder blocks. The system pre-machines temperature measurement holes on the cylinder block base, connects a temperature measuring device to a thermocouple, and installs the thermocouple in the temperature measurement holes on the cylinder block base. This allows the temperature of the hydraulic bimetallic cylinder block during the casting process to be measured. Based on the accurately recorded actual temperature of the cylinder block base, the system can reflect temperature changes in the cylinder block base. By adjusting the heating temperature and heating time, different parts of the cylinder block base can reach the same temperature, providing a reference for the casting process and enabling more efficient casting, thereby improving the quality of the hydraulic bimetallic cylinder block.

[0026] The temperature measurement system for the preparation of hydraulic bimetallic cylinder blocks by casting, provided in the embodiments of this application, will be described below with reference to the accompanying drawings.

[0027] This application discloses a temperature measurement system for the fabrication of hydraulic bimetallic cylinder blocks. For example... Figure 1 As shown, the temperature measurement system used for the preparation of hydraulic bimetallic cylinder block casting includes a temperature measuring hole 3, a thermocouple 4, and a temperature measuring device 5; wherein, the temperature measuring hole 3 is opened on the cylinder block base 1; the thermocouple 4 is assembled in the temperature measuring hole 3 and is used to measure the temperature of the cylinder block base 1; the temperature measuring device 5 is connected to the thermocouple 4 and is used to receive and output the temperature value of the cylinder block base 1.

[0028] By using the temperature measurement system in this technical solution, a temperature measuring hole 3 is pre-machined on the cylinder base 1, a temperature measuring device 5 is connected to a thermocouple 4, and the thermocouple 4 is installed in the temperature measuring hole 3 located on the cylinder base 1 (e.g., Figure 1 (As indicated by the arrow) The temperature measuring device 5 is used to measure the temperature of the hydraulic bimetallic cylinder during the casting process. Based on the accurate recording of the actual temperature of the cylinder base 1, the temperature change of the cylinder base 1 is reflected. By adjusting the heating temperature and heating time, different parts of the cylinder base 1 can reach the same temperature, providing a reference for the casting process formulation. This allows for more effective casting and improves the quality of the hydraulic bimetallic cylinder.

[0029] In some embodiments of this utility model, such as Figure 1 As shown, multiple temperature measuring holes 3 are provided on the cylinder base 1 and are distributed in a dispersed manner.

[0030] In this embodiment, by opening multiple temperature measuring holes 3 on the cylinder base 1 and dispersing them, and installing thermocouples 4 in each temperature measuring hole 3, the temperature changes of different parts of the cylinder base 1 can be reflected more comprehensively, thereby further improving the accuracy of heating temperature and heating time adjustment.

[0031] It should be noted that in this embodiment, the multiple thermocouples 4 can be connected to a temperature measuring device 5 through wires, or the multiple thermocouples 4 can be connected to multiple temperature measuring devices 5 through wires. The thermocouples 4 can accurately measure the temperature of the cylinder base 1 at the temperature measuring hole 3 and feed it back to the temperature measuring device 5 and output it accurately. This is not limited here.

[0032] In some embodiments of this utility model, such as Figure 2 As shown, the temperature measuring hole 3 includes a first hole 6, a second hole 7, a third hole 8, and a fourth hole 9; wherein, the first hole 6 is located near the surface of the cylinder base 1; the second hole 7 is located near the center hole 2 of the cylinder base 1; the third hole 8 is located near the center hole 2 of the cylinder base 1 and near the place where the metal block is placed; and the fourth hole 9 is located near the deepest internal point of the cylinder base 1.

[0033] In this embodiment, considering that the volume of the steel substrate in the cylinder is several times that of the copper layer, and the thickness is hundreds of times greater, and that the thermal conductivity of copper is much greater than that of steel, the first hole 6 can effectively reflect the temperature of the area where the cylinder substrate 1 heats up the fastest, the second hole 7 can effectively reflect the temperature change at the central hole 2 of the cylinder substrate 1, the third hole 8 can effectively reflect the temperature of the copper block (molten copper), and the fourth hole 9 can effectively reflect the temperature of the area where the cylinder heats up the slowest. By measuring the surface, core, and near-molten copper surface of the cylinder substrate 1, the temperature of the inside and outside of the cylinder and the copper block can be effectively measured at these representative locations, thereby more effectively monitoring the temperature changes of different parts of the cylinder substrate 1.

[0034] It should be noted that, depending on the structure of the cylinder base 1, in addition to setting the first hole 6, the second hole 7, the third hole 8 and the fourth hole 9 on the cylinder base 1, temperature measuring holes 3 can also be set at other positions on the cylinder base 1 as needed, so as to cover the monitoring of the temperature of different parts of the cylinder base 1 as much as possible. No limitation is made here.

[0035] Furthermore, there can be more than two third holes 8, which are located near different positions of the copper block (molten copper).

[0036] It should be noted that, depending on the specifications of the cylinder base 1, multiple first holes 6, second holes 7 and fourth holes 9 may be provided, and no limitation is made here.

[0037] like Figure 2 As shown, in one embodiment of this utility model, there is one first hole 6, one second hole 7 and one fourth hole 9, and two third holes 8.

[0038] In this embodiment, in the height direction, the first hole 6 (position 1) is located less than 15mm from the bottom surface of the cylinder base 1; in the diameter direction, the first hole 6 is located at half the radius of the bottom surface of the cylinder body minus the radius of the center hole 2; in the diameter direction, the second hole 7 (position 2) is located less than 15mm from the wall of the center hole 2 on the bottom surface of the cylinder base 1; in the height direction, the second hole 7 is located at half the height of the center hole 2 on the bottom surface of the cylinder base 1; in the height direction, both third holes 8 are located less than 3mm from the molten copper surface; in the diameter direction, one third hole 8 (position 3) is located at half the radius of the upper end face of the cylinder body minus the radius of the center hole 2 on the upper end face, and the other third hole 8 (position 4) is located less than 15mm from the copper layer boundary; in both the height and diameter directions, the fourth hole 9 (position 5) is located at half the thickness of the thickest part of the cylinder body. The temperature measurement results for positions 1-5 are as follows: Figure 3 As shown.

[0039] In some embodiments of this utility model, such as Figure 1and Figure 2 As shown, the temperature measuring hole 3 is a blind hole, and the temperature measuring hole 3 extends from the outer surface of the cylinder base 1 into the cylinder base 1.

[0040] It should be understood that, in this embodiment, the bottom of the blind hole is the temperature measurement position. When the temperature measurement hole 3 is a blind hole, the bottom of the blind hole can be arranged close to the skin of the cylinder base 1, the center hole 2, the metal block, the deepest internal point, etc.

[0041] By making the temperature measuring hole 3 a blind hole, the contact between the inner space of the temperature measuring hole 3 and the outside of the cylinder base 1 can be reduced, so that the temperature measuring hole 3 can more accurately reflect the temperature at the measuring position and reduce errors.

[0042] Furthermore, the temperature measuring holes 3 are distributed on the side of the cylinder base 1. The diameter of the temperature measuring holes 3 is variable, and the maximum included angle between the axis of the temperature measuring holes 3 and the horizontal plane is <30°.

[0043] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the temperature measuring system also includes a plug 10, which is installed at the open end of the temperature measuring hole 3. The plug 10 has a through hole 11 along the length of the temperature measuring hole 3, and the thermocouple 4 is inserted into the through hole 11 and extends into the depth of the temperature measuring hole 3.

[0044] In this embodiment, the plug 10 can both assemble the thermocouple 4 and the temperature measuring hole 3 and further enhance the independence of the space inside the temperature measuring hole 3.

[0045] In some embodiments of this utility model, the plug 10 is a bolt, and the open end of the temperature measuring hole 3 is threadedly engaged with the bolt.

[0046] In other embodiments of this utility model, the plug 10 can also be assembled with the temperature measuring hole 3 by means of plugging or other methods, so as to stably connect the thermocouple 4 to the cylinder base 1 and seal the temperature measuring hole 3, which is not limited here.

[0047] In some embodiments of this utility model, such as Figure 4 As shown, the plug 10 has a through hole 12. One end of the through hole 12 is connected to the through hole 11, and the other end extends to the outer surface of the plug 10. A rod (not shown) for tightening and limiting the thermocouple 4 is installed in the through hole 12.

[0048] In this embodiment, after the thermocouple 4 is inserted into the through hole 11 of the plug 10, the position of the rod in the through hole 12 can be adjusted to make the rod press against the thermocouple 4 and lock the thermocouple 4, thereby improving the connection stability between the thermocouple 4 and the plug 10 and the cylinder base 1.

[0049] In one embodiment of this utility model, the through hole 12 is provided along the diameter direction of the bolt exposed to the outside. The through hole 12 is a hole with an internal thread and a diameter of <2mm. The rod is a cylindrical threaded rod that meshes with the through hole 12.

[0050] In some embodiments of this utility model, the diameter of the temperature measuring hole 3 near its inner end is <3mm; preferably, the diameter of the thermocouple 4 is <1.6mm; thereby more accurately measuring the temperature at the set position and reducing the impact on the cylinder structure; for example, in one specific embodiment, the diameter of the temperature measuring hole 3 near its inner end is 2.9mm, and the diameter of the thermocouple 4 is 1.5mm.

[0051] Furthermore, to facilitate the installation of the plug 10, the maximum diameter of the temperature measuring hole 3 near the surface of the cylinder base 1 can be set to <20mm; for example, in one specific embodiment, the maximum diameter of the temperature measuring hole 3 near the surface of the cylinder base 1 is 18mm.

[0052] In some embodiments of this utility model, the thermocouple 4, in conjunction with the temperature measuring device 5, is required to have an accuracy of within ±5℃ and a maximum range of 1200℃.

[0053] In some embodiments of this utility model, the temperature measuring device 5 includes, but is not limited to, electrical instruments such as temperature measuring instruments.

[0054] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
