Description

Technical Field

[0001] This utility model relates to the field of quenching technology, and more specifically, to a quenching tool and quenching system for plate-shaped workpieces. Background Technology

[0002] During quenching, a high-temperature workpiece is cooled down to a relatively low temperature, causing a phase transformation in the workpiece's microstructure, thereby improving its mechanical properties.

[0003] In related technologies, when quenching large plate-shaped workpieces, the workpieces need to be placed vertically in the quenching tank. The liquid circulation efficiency on both sides of the plate-shaped workpieces is low, and the liquid temperature is high, which cannot guarantee the quenching effect. Insufficient quenching is likely to occur at the edges and other positions of the workpieces, resulting in unqualified internal structure or even scrapping of the workpieces. Utility Model Content

[0004] The problem this invention aims to solve is how to improve the overall quenching effect of plate-shaped workpieces.

[0005] To address the aforementioned problems, in a first aspect, this utility model provides a quenching auxiliary tool for plate-shaped workpieces, which is used to be installed in a quenching tank. The quenching auxiliary tool includes a liquid collecting component and a guide pipe. The liquid collecting component is used to connect with a liquid supply assembly, and the guide pipe is connected to the liquid collecting component in a through manner. The liquid collecting component has a first guide hole, which corresponds to the middle part of the plate-shaped workpiece and is used to assist in the quenching of the middle part of the plate-shaped workpiece. The guide pipe has a second guide hole, and a third guide hole is provided at the end of the guide pipe away from the liquid collecting component. The third guide hole and the second guide hole correspond to the side part of the plate-shaped workpiece and are used to assist in the quenching of the side part of the plate-shaped workpiece.

[0006] Optionally, the first guide hole is used to be tilted toward the plate-shaped workpiece.

[0007] Optionally, the liquid collecting component is cylindrical, and the first guide hole is provided in multiple and evenly distributed circumferentially on the side wall of the liquid collecting component.

[0008] Optionally, at least two guide pipes are provided, each guide pipe corresponding to the side of the plate-shaped workpiece, and the first guide hole is used to tilt towards the middle of the plate-shaped workpiece.

[0009] Optionally, the guide pipe is detachably connected to the liquid collection component, and at least two of the guide pipes are configured at a preset angle to be parallel to the plate-shaped workpiece or to correspond to the two sides of the angled irregular plate-shaped workpiece.

[0010] Optionally, one end of the guide pipe near the liquid collecting element is connected to the liquid collecting element, and the connection position between the two is different from that of the first guide hole.

[0011] Optionally, the end of the guide pipe near the liquid collecting element is perpendicular to the side wall of the liquid collecting element, and the vertical height of the connection position between the guide pipe and the liquid collecting element is lower than the vertical height of the first guide hole.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0021] Reference Figure 1 and Figure 3 As shown in the figure, this utility model embodiment proposes a quenching auxiliary tool for plate-shaped workpieces, which is used to be set in a quenching tank 8. The quenching auxiliary tool includes a liquid collecting component 1 and a guide pipe 7. The liquid collecting component 1 is used to connect to the liquid supply component 12. The guide pipe 7 is connected to the liquid collecting component 1. The liquid collecting component 1 is provided with a first guide hole 3, which corresponds to the middle part of the plate-shaped workpiece and is used to assist in the quenching of the middle part of the plate-shaped workpiece. The guide pipe 7 is provided with a second guide hole 4. The end of the guide pipe 7 away from the liquid collecting component 1 is provided with a third guide hole 2. The third guide hole 2 and the second guide hole 4 correspond to the side part of the plate-shaped workpiece and are used to assist in the quenching of the side part of the plate-shaped workpiece.

[0022] Specifically, when quenching a plate-shaped workpiece, the quenching auxiliary fixture is pre-set at the center of the bottom inside the quenching tank 8, and is arranged according to the length or width of the plate-shaped workpiece so that the guide pipe 7 can correspond to the side of the plate-shaped workpiece, such as... Figure 1 As shown, two guide pipes 7 are arranged along the length of the quenching pool 8. Cooling liquid medium (such as water, polymer quenching liquid, etc.) is introduced into the liquid collection component 1 through the liquid supply component 12. During quenching, the plate-shaped workpiece to be quenched needs to be hooked by an overhead crane and fall along the center line of the quenching pool 8. It moves up and down in the liquid medium environment above the liquid collection component 1. The lower temperature liquid medium is sprayed out in a divergent manner in the quenching pool 8 through the first guide hole 3 of the liquid collection component 1. Due to the relative position, it can act on the plate-shaped workpiece above the relative position, especially the middle position of the plate-shaped workpiece, to ensure sufficient circulation of the liquid medium in the middle of the large plate-shaped workpiece. The large plate-shaped workpiece refers to the plate-shaped workpiece whose absolute value of the difference between its length or width and the width of the quenching pool 8 is within a preset range, which is the interval from 0 to a preset threshold. Another part enters the guide pipe 7 and passes through the second guide hole 4 and the third guide hole on it. The liquid medium is directed out through hole 2. Due to the relative position, it can act on the side of the plate-shaped workpiece, ensuring sufficient circulation of the liquid medium on both sides of the large plate-shaped workpiece. The liquid medium directed out through the second guide hole 4 can act on the side near the middle; the liquid medium directed out through the third guide hole 2 can act on the edge of the side. The liquid medium in the quenching tank 8 is heated through circulation. When the liquid medium around the plate-shaped workpiece is heated by the high-temperature workpiece, the flow of the high-temperature liquid medium tends to be slow and gradually disperses into the tank. Then, the liquid medium cooled by the outside is directed out through each guide hole. The space around the plate-shaped workpiece is filled with new low-temperature liquid medium. Thus, the quenching auxiliary tool continuously guides the liquid to form a circulation near the large plate-shaped workpiece, ensuring that the lower-temperature liquid medium surrounds the entire plate-shaped workpiece, so that the workpiece is always in a relatively low environment, improving the overall quenching effect.

[0023] In this embodiment, the liquid collecting component 1 is connected to the liquid supply assembly 12, and the guide pipe 7 is connected to the liquid collecting component 1. The liquid collecting component 1 is provided with a first guide hole 3, which corresponds to the middle of the plate-shaped workpiece. This allows the liquid medium to act in a divergent manner through the first guide hole 3 on the liquid collecting component 1 to the middle of the plate-shaped workpiece, promoting liquid circulation in the middle of the plate-shaped workpiece and ensuring the quenching effect in the middle of the plate-shaped workpiece. The end of the guide pipe 7 away from the liquid collecting component 1 is provided with a third guide hole 2, and the third guide hole 2 and the second guide hole 4 are connected to the plate-shaped workpiece. Corresponding to the side of the workpiece, the third guide hole 2 and the second guide hole 4 can both control the liquid medium to act on the side of the plate-shaped workpiece from a specific position, ensuring the quenching effect of the side (and even both sides) of the plate-shaped workpiece. In summary, with the quenching auxiliary tool provided by this utility model, the low-temperature liquid medium surrounds the plate-shaped workpiece to be quenched from bottom to top, which can promote the circulation of the low-temperature liquid medium in the middle and both sides of the plate-shaped workpiece, cool down the entire workpiece, significantly improve the quenching effect of large plate-shaped workpieces, and help improve production efficiency.

[0024] like Figure 1 and Figure 3 As shown, in an optional embodiment of the present invention, the first guide hole 3 is used to be tilted toward the plate-shaped workpiece.

[0025] Specifically, there is at least one first guide hole 3. After the first guide hole 3 is placed in the quenching tank 8, the first guide hole 3 faces the plate-shaped workpiece. When the liquid collecting component 1 is placed vertically, the first guide hole 3 is set to be inclined upward. Since the liquid collecting component 1 is generally located in the middle of the quenching tank 8, the first guide hole 3 is used to be inclined towards the plate-shaped workpiece. This ensures that the cooled liquid medium is sprayed out in a divergent manner through the first guide hole 3 on the liquid collecting component 1, acting on the middle of the plate-shaped workpiece, promoting the liquid circulation in the middle of the quenching tank 8, and ensuring the quenching effect in the middle of the vertically placed plate-shaped workpiece.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the liquid collecting component 1 is cylindrical, and the first guide hole 3 is provided in a plurality of manner and is evenly distributed circumferentially on the side wall of the liquid collecting component 1. The first guide hole 3 is used to tilt toward the middle position of the plate-shaped workpiece.

[0027] Specifically, the liquid collecting component 1 is configured as a hollow cylindrical shape, with first guide holes 3 evenly distributed on the side wall of the liquid collecting component 1. This ensures that the liquid medium passes through the first guide holes 3 on the liquid collecting component 1 and is sprayed out from the first guide holes 3 in a divergent manner, acting on the middle of the plate-shaped workpiece, thus ensuring the circulation of the low-temperature liquid medium in the middle of the large plate-shaped workpiece. This works in conjunction with the liquid medium acting on the side of the plate-shaped workpiece through the third guide holes 2 and the second guide holes 4 on each guide pipe 7, thereby improving the overall cooling effect of the plate-shaped workpiece corresponding to the liquid medium.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, at least two guide pipes 7 are provided, and each guide pipe 7 corresponds to the side of the plate-shaped workpiece.

[0029] Specifically, at least two guide pipes 7 are provided, and both guide pipes 7 are connected to the liquid collection component 1. Each guide pipe 7 corresponds to the side of a plate-shaped workpiece. The two guide pipes 7 correspond to the two sides of the plate-shaped workpiece. After the quenching auxiliary tool is placed in the quenching pool 8, the side of the plate-shaped workpiece is aligned with the corresponding guide pipe 7 on the quenching auxiliary tool, and then it moves up and down. The third guide hole 2 and the second guide hole 4 on each guide pipe 7 act on the side of the plate-shaped workpiece. The low-temperature liquid medium acts on the corresponding side, so that the (two) sides of the plate-shaped workpiece are surrounded by the low-temperature liquid medium, thereby improving the quenching effect of the plate-shaped workpiece corresponding to the liquid medium.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the guide pipe 7 is detachably connected to the liquid collecting component 1, and at least two of the guide pipes 7 are configured at a preset angle to be parallel to the plate-shaped workpiece or to correspond to the two sides of the angled irregular plate-shaped workpiece respectively.

[0031] Specifically, when the plate-shaped workpiece is elongated, at least two guide pipes 7 are arranged at a 180-degree angle; when the plate-shaped workpiece is an angled, irregularly shaped, large plate-shaped workpiece, the two guide pipes 7 can be at a certain angle for quenching the angled, irregularly shaped, large plate-shaped workpiece. The angle deviation between the two can be set within a preset range. For example, if the angle of the plate-shaped workpiece is 20 degrees, the two guide pipes 7 can be at 25 degrees to quench the side of the plate-shaped workpiece. To achieve this, the side wall of the liquid collecting component 1 is provided with several circumferentially arranged mounting holes (not shown in the figure). When not in use, the mounting holes are plugged with hole plugs or secured with bolts. When it is necessary to adjust the installation angle of the guide pipes 7, the guide pipes 7 are selected at an appropriate angle along the circumference of the liquid collecting component 1 and then connected by threads; or they can be connected with bolts. Bolt mounting lugs can be provided on the guide pipes 7, thereby ensuring that the liquid medium sprayed from at least two of the guide pipes 7 always acts on the side of the plate-shaped workpiece, thereby improving the overall quenching effect of the plate-shaped workpiece in conjunction with the central liquid collecting component 1.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment of this utility model, the end of the guide pipe 7 near the liquid collecting component 1 is connected to the liquid collecting component 1, and the connection position between the two is different from the position of the first guide hole 3.

[0033] Specifically, the guide pipe 7 is connected to the liquid collecting component 1, and the liquid medium in the liquid collecting component 1 can enter the guide pipe 7. The position of the guide pipe 7 and the liquid collecting component 1 does not conflict with the position of the first guide hole 3. The guide pipe 7 can be connected to the side wall of the liquid collecting component 1 and staggered from the position of the first guide hole 3 to avoid the two being too close to affect the direction of action of the liquid medium coming out of the first guide hole 3, thereby affecting the quenching effect on the middle position of the plate-shaped workpiece.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment of this utility model, the end of the guide pipe 7 near the liquid collecting member 1 is perpendicular to the side wall of the liquid collecting member 1, and the vertical height of the connection position between the guide pipe 7 and the liquid collecting member 1 is lower than the vertical height of the first guide hole 3.

[0035] Specifically, the connection between the guide pipe 7 and the liquid collecting component 1, that is, the position of the guide pipe 7 near the liquid collecting component 1, is perpendicular to the side wall of the liquid collecting component 1 and remains connected. This allows the liquid filling the liquid collecting component 1 to smoothly enter the guide pipe 7 under pressure, and then be ejected through the second guide hole 4 and the third guide hole 2, reducing liquid resistance. Furthermore, the vertical height of the connection position between the guide pipe 7 and the liquid collecting component 1 is lower than the vertical height of the first guide hole 3. Therefore, when there are a large number of first guide holes 3, the guide pipe 7 will not obstruct the liquid medium ejected from the first guide holes 3, so as to avoid affecting the quenching effect on the middle position of the plate-shaped workpiece.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the guide pipe 7 includes a horizontal pipe section 5 and an inclined pipe section 6 that are connected through each other. The end of the horizontal pipe section 5 away from the inclined pipe section 6 is connected to the liquid collecting member 1. At least the horizontal pipe section 5 is provided with a second guide hole 4, which is used to face the side of the plate-shaped workpiece. The third guide hole 2 is provided at the end of the inclined pipe section 6 away from the horizontal pipe section 5, and the third guide hole 2 is inclined towards the side wall of the quenching pool 8.

[0037] Specifically, one end of the horizontal pipe section 5 is connected to and maintains communication with the liquid collecting component 1. The horizontal pipe section 5 can be understood as a straight section. The horizontal pipe section 5 has evenly spaced upward-facing second guide holes 4, or some of the second guide holes 4 face upwards, while the others face the side wall of the quenching pool 8. When the liquid collecting component 1 is located at the bottom of the inner side of the quenching pool 8, the inclined pipe section 6 is set to be inclined. The end of the inclined pipe section 6 is a third guide hole 2. The third guide hole 2 is inclined towards the inner side wall of the quenching pool 8. Through the backflow action of the inner side wall, the cooling range is expanded, so that the liquid medium can fully act on the side of the plate-shaped workpiece to achieve sufficient circulating cooling. Through the action of the liquid medium sprayed from the second guide hole 4 and the third guide hole 2 on the guide pipe 7, the lower temperature liquid can surround the side of the plate, improving the quenching cooling effect.

[0038] As an optional embodiment of this utility model, the third guide hole 2, the first guide hole 3, and the second guide hole 4 are all configured to be pluggable.

[0039] Specifically, the third guide hole 2, the first guide hole 3, and the second guide hole 4 are all configured with corresponding sealing plugs, so that the third guide hole 2, the first guide hole 3, and the second guide hole 4 can be opened or closed according to the quenching requirements in actual production, so as to adapt to plate-shaped workpieces of different specifications and quenching requirements; for example, for plate-shaped workpieces with smaller dimensions, the second guide holes 4 on both sides of the horizontal pipe section 5 can be partially sealed to meet the actual quenching requirements.

[0040] like Figure 3 As shown, this utility model proposes a quenching system, including the quenching auxiliary tool as described above, as well as a quenching pool 8, a cooling component 11, and a liquid supply component 12. The quenching auxiliary tool is used to be installed in the quenching pool 8. The liquid supply component 12 is connected to the liquid collection component 1 of the quenching auxiliary tool and is used to supply the cooled liquid medium. The cooling component 11 is used to draw the liquid medium in the quenching pool 8 through the return pipe 10 for cooling and to transport it to the liquid supply component 12.

[0041] The cooling assembly 11 can be a plate heat exchanger, which is composed of a series of corrugated metal plates stacked together, forming complex flow channels between the plates. The liquid medium and the exchange liquid flow in opposite directions in adjacent flow channels, and efficient heat exchange is achieved through the thin plates. The liquid supply assembly 12 is used for external storage of liquid medium. The return pipe 10 or the cooling assembly 11 generally also has the function of pumping liquid medium from the quenching tank 8, for example, by installing a water pump.

[0042] Specifically, when plate-shaped workpieces undergo performance heat treatment in a quenching system, the following steps are followed. 1. Heat preservation before quenching; Heat the workpiece to 50°C above the critical temperature (Ac3 for hypoeutectoid steel, Ac1 for eutectoid steel). Determine the total holding time based on the workpiece thickness, increasing the time by one hour for every 50mm of thickness. During heat preservation, a stepped heat preservation method is adopted. When the heat preservation time reaches one-third and two-thirds of the total heat preservation time, the temperature of the return pipe is reduced by 10°C. The purpose of heat preservation is to austenitize the workpiece and prepare it for quenching; the stepped design is used to reduce thermal stress and lower the risk of cracking in large plate-shaped workpieces.

[0043] 2. Use special auxiliary tools and quenching tank 8 to perform full quenching; During quenching, the workpiece needs to be hooked by an overhead crane and moved up and down on a special auxiliary fixture. The high temperature on the surface of the workpiece causes the liquid to vaporize, forming a gas film that affects the contact between the liquid and the workpiece. The movement, combined with the impact force of the liquid sprayed out by the special auxiliary fixture, can break the gas film and enhance the quenching effect. In addition, the liquid supply assembly 12 is connected to the liquid collection component 1, so that the liquid medium enters the quenching pool 8 in a divergent manner through the first guide hole 3 on the liquid collection component 1, promoting the liquid circulation in the middle of the quenching pool 8 and ensuring the quenching effect in the middle of the vertically placed plate-shaped workpiece. At the same time, the liquid medium is controlled to enter the quenching pool 8 from a specific position through the guide pipe 7 and its third guide hole 2 and second guide hole 4, ensuring the quenching effect on both sides of the plate-shaped workpiece. The quenching auxiliary fixture of a specific shape guides the liquid medium to form a circulation near the large plate-shaped workpiece, so that the workpiece can be in a relatively low temperature environment, improving the quenching effect.

[0044] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features of the present invention.

[0045] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
