Description

Technical Field

[0001] This application relates to the field of mold steel processing technology, and in particular to a high-efficiency cutting device for mold steel. Background Technology

[0002] Mold steel, a type of steel specifically designed for manufacturing various molds, is a special steel designed to meet the unique requirements of molds operating under extreme conditions such as high temperature, high pressure, and high friction. It is a core material in mold manufacturing. High-efficiency cutting devices, specialized equipment or tools for quickly and accurately cutting mold steel, play a vital role by improving cutting efficiency, reducing labor intensity, and simplifying operation while ensuring cutting quality.

[0003] An existing technology provides a high-efficiency cutting device for mold steel, comprising a moving guide rail, a device body, an operating handle, an adjusting mechanism, and a flame cutting head. The device body is slidably connected to the moving guide rail, allowing it to slide along the extension direction of the guide rail. The operating handle is mounted on the device body, and the adjusting mechanism is mounted at the end of the operating handle. The flame cutting head is mounted on the operating handle via the adjusting mechanism, which is used to adjust the position of the flame cutting head in the height and length direction of the operating handle. Before use, the user adjusts the position of the flame cutting head using the adjusting mechanism. After adjustment, the user moves the device body by holding the operating handle to perform cutting.

[0004] Regarding the aforementioned technologies, existing adjustment mechanisms typically employ a linkage or shared drive source for adjusting height and the length of the operating handle. This allows for adjustment in both directions with only one drive component. However, this increases the likelihood that adjusting one direction will cause a shift in the other direction, leading to repeated adjustments by the operator and reducing the efficiency of adjusting the flame cutting head. Therefore, improvements are needed. Summary of the Invention

[0005] To increase the efficiency of adjusting the position of the flame cutting head, this application provides a high-efficiency cutting device for mold steel.

[0006] This application provides a high-efficiency cutting device for mold steel, which adopts the following technical solution: A high-efficiency cutting device for mold steel includes a movable slide rail and a device body. The device body is further provided with an operating handle and a flame cutting head. The operating handle is provided with an adjustment mechanism, which includes a first adjustment frame and a second adjustment frame. The first adjustment frame is slidably connected to the operating handle, and the sliding direction is the length direction of the operating handle. The first adjustment frame is also provided with a first fastening mechanism for fixing the first adjustment frame and the operating handle. The second adjustment frame is slidably connected to the first adjustment frame, and the sliding direction is the height direction of the device body. The second adjustment frame is also provided with a second fastening mechanism for fixing the second adjustment frame and the first adjustment frame. The flame cutting head is mounted on the second adjustment frame.

[0007] By adopting the above technical solution and configuring the adjustment mechanism, when the position of the flame cutting head needs to be adjusted, the operator can drive the first adjustment frame to slide relative to the operating handle, thereby adjusting the first adjustment frame in the length direction of the operating handle. Furthermore, the operator can also drive the second adjustment frame to slide independently relative to the first adjustment frame, thereby adjusting the second adjustment frame in the height direction. This effectively allows the position adjustment of the flame cutting head in the height direction and the length direction of the operating handle to be performed independently, thus reducing the probability of interference between the two directions and the need for repeated adjustments by the operator. This effectively ensures the efficiency of flame cutting head adjustment and facilitates operator operation.

[0008] Preferably, the first fastening mechanism includes a fastening bolt and a fastening nut. The fastening nut is located on one side of the operating handle. The fastening bolt is disposed on the first adjusting frame, and one end passes through the first adjusting frame away from the fastening nut, through the first adjusting frame and the operating handle. The fastening nut is sleeved on the fastening bolt and is threadedly connected to the fastening bolt.

[0009] By adopting the above technical solution and setting the first fastening mechanism, after the operator adjusts the position of the first adjusting frame, he can tighten the fastening nut so that the fastening nut and the fastening bolt can fix the first adjusting frame and the operating handle after tightening, which effectively ensures the stability of the first adjusting frame after adjustment.

[0010] Preferably, the first adjusting frame is further provided with a fastening handle, a driving assembly, a rotating sleeve, and an intermediate sleeve. One end of the fastening handle is rotatably connected to the first adjusting frame. The intermediate sleeve is connected to the fastening nut and is sleeved on the rotating sleeve, and is slidably connected to the rotating sleeve. The sliding direction is the axial direction of the fastening nut. The rotating sleeve is rotatably connected to the first adjusting frame. The fastening handle is used to drive the rotating sleeve to rotate through the driving assembly.

[0011] By adopting the above technical solution, the setting of the fastening handle, drive assembly, rotating sleeve and intermediate sleeve allows the operator to drive the fastening handle to rotate, which in turn drives the rotating sleeve to rotate, which in turn drives the intermediate sleeve to rotate, which in turn drives the fastening nut to rotate, thus loosening or tightening the fastening nut onto the fastening bolt. This effectively facilitates the operator in fixing the first adjustment frame, thereby improving the efficiency of adjusting the flame cutting head.

[0012] Preferably, the driving assembly includes a driving rod and a driving member. One end of the driving rod is inserted into the opening of the rotating sleeve. A spiral groove is also formed on the inner wall of the opening of the rotating sleeve. An abutment rod is also provided on the driving rod. One end of the abutment rod is embedded in the spiral groove and abuts against the inner wall of the spiral groove. The fastening handle is used to drive the driving rod to move along the axial direction of the rotating sleeve through the driving member.

[0013] By adopting the above technical solution and specifically configuring the drive component, the fastening handle can drive the drive rod to slide through the drive component, thereby enabling the abutment rod on the drive rod to abut against the inner wall of the spiral groove, driving the rotating sleeve to rotate, and thus converting the rotation of the rotating sleeve into the movement of the drive rod, effectively facilitating the driving of the rotating sleeve.

[0014] Preferably, the driving component includes a transmission frame and a sliding frame. One end of the transmission frame is rotatably connected to the fastening handle, and the other end is rotatably connected to the sliding frame. The sliding frame is slidably connected to the first adjusting frame, and the sliding direction is parallel to the axial direction of the rotating sleeve. The sliding frame is connected to the driving rod.

[0015] By adopting the above technical solution, the transmission frame and the sliding frame are configured so that when the fastening handle rotates, the fastening handle can drive the sliding frame to slide through the transmission frame, thereby causing the sliding frame to drive the drive rod to slide together, thus driving the drive rod and realizing the transmission between the fastening handle and the fastening nut. This effectively facilitates the worker's fixation of the first adjustment frame and improves the efficiency of adjusting the flame cutting head.

[0016] Preferably, the second adjusting frame is further provided with an adjusting component, which includes an adjusting gear and an adjusting rack. The adjusting gear is rotatably connected to the first adjusting frame, and the adjusting rack is connected to the second adjusting frame and extends in a direction parallel to the sliding direction of the second adjusting frame. The adjusting gear and the adjusting rack mesh with each other.

[0017] By adopting the above technical solution and setting the adjustment component, the operator can drive the adjustment gear to rotate, so that the adjustment gear, through the adjustment rack, causes the second adjustment frame to slide relative to the first adjustment frame, which effectively improves the sliding accuracy of the second adjustment frame and facilitates the operator's control over the height of the second adjustment frame.

[0018] Preferably, the second fastening mechanism includes an additional plate and two fastening chucks. The additional plate is connected to the adjusting gear. The two fastening chucks are located on opposite sides of the additional plate and are rotatably connected to the first adjusting frame. The sides of the two fastening chucks that are close to each other are sleeved on the additional plate and are in contact with the side wall of the additional plate.

[0019] By adopting the above technical solution, the second fastening mechanism is designed so that the fastening chuck can rotate after the second adjusting frame slides, thereby allowing the end of the additional plate to be embedded in the fastening chuck. Then, the fastening chuck fixes the additional plate by the friction force when it is in contact with the side wall of the additional plate, thereby fixing the second adjusting frame. This effectively facilitates the operation of the staff and ensures the stability during fixing.

[0020] Preferably, the first adjusting frame is further provided with a transmission mechanism, which includes a drive frame, a transmission slider and a linkage. The number of drive frames is set to several, and they correspond to the two fastening chucks. One end of each drive frame is rotatably connected to the corresponding fastening chuck, and the other end is rotatably connected to the transmission slider. The transmission slider is slidably connected to the first adjusting frame. The sliding frame drives the transmission slider to slide through the linkage.

[0021] By adopting the above technical solution and configuring the transmission mechanism, the sliding frame can drive the transmission slider to slide through the linkage. As the transmission slider slides, it drives each fastening chuck through several drive frames. This allows the operator to fix the first adjustment frame and the second adjustment frame through the fastening handle, which effectively facilitates the operator's operation and improves the adjustment efficiency of the flame cutting head.

[0022] Preferably, the linkage component includes a linkage frame, one end of which is rotatably connected to the sliding frame, and the other end of which is rotatably connected to the transmission slider.

[0023] By adopting the above technical solution and setting the linkage frame, when the sliding frame slides, the sliding frame can drive the transmission slider to slide through the linkage frame, thereby realizing the drive of the transmission slider, effectively realizing the transmission between the sliding frame and the transmission slider, and ensuring the continuity of the transmission.

[0024] Preferably, the first adjustment frame includes a sliding sleeve and a rotating sleeve. The sliding sleeve is fitted onto the operating handle and is slidably connected to the operating handle, with the sliding direction being the length direction of the operating handle. The rotating sleeve is rotatably connected to the sliding sleeve, and the second adjustment frame is slidably connected to the rotating sleeve.

[0025] By adopting the above technical solution and setting the first adjustment frame, the operator can drive the rotating sleeve to rotate, thereby adjusting the cutting angle of the flame cutting head, which effectively improves the adjustment effect and increases the practicality and scope of application of this application.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The adjustment mechanism is designed so that when the position of the flame cutting head needs to be adjusted, the operator can drive the first adjustment frame to slide relative to the operating handle to adjust the first adjustment frame in the length direction of the operating handle. The operator can also drive the second adjustment frame to slide independently relative to the first adjustment frame to adjust the height direction of the second adjustment frame. This effectively allows the position adjustment of the flame cutting head in the height direction and the length direction of the operating handle to be carried out independently, thereby reducing the probability of interference between the two directions and reducing the probability of repeated adjustments by the operator. This effectively ensures the efficiency of flame cutting head adjustment and facilitates the operation of the operator. 2. The design of the fastening handle, drive assembly, rotating sleeve, and intermediate sleeve allows the operator to rotate the fastening handle, which in turn drives the rotating sleeve to rotate via the drive assembly. This, in turn, causes the intermediate sleeve to rotate, which in turn causes the fastening nut to rotate, allowing the fastening nut to be loosened or tightened onto the fastening bolt. This effectively facilitates the operator's fixation of the first adjustment frame, thereby improving the efficiency of adjusting the flame cutting head. 3. The transmission mechanism is designed so that the sliding frame can drive the transmission slider to slide through the linkage. When the transmission slider slides, it drives each fastening chuck through several drive frames. This allows the operator to fix the first and second adjustment frames through the fastening handle, which effectively facilitates the operator's operation and improves the adjustment efficiency of the flame cutting head.

[0037] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0038] Example 1

[0039] Embodiment 1 of this application discloses a high-efficiency cutting device for mold steel. (Refer to...) Figure 1 and Figure 2The high-efficiency cutting device for mold steel includes a sliding rail 1 and a device body 2. The device body 2 is also equipped with an operating handle 3 and a flame cutting head 4. The operating handle 3 is equipped with an adjustment mechanism 5, which includes a first adjustment frame 51 and a second adjustment frame 52. The first adjustment frame 51 is slidably connected to the operating handle 3, and the sliding direction is along the length of the operating handle 3. The first adjustment frame 51 is also equipped with a first fastening mechanism 6 for fixing the first adjustment frame 51 to the operating handle 3. The second adjustment frame 52 is slidably connected to the first adjustment frame 51, and the sliding direction is along the height of the device body 2. The second adjustment frame 52 is also equipped with a second fastening mechanism 7 for fixing the second adjustment frame 52 to the first adjustment frame 51. The flame cutting head 4 is mounted on the second adjustment frame 52.

[0040] Reference Figure 1 The device body 2 is also provided with a movable slide rail 1 below it. The movable slide rail 1 is used to fix and install the device body 2 on the cutting table or worktable for placing the mold steel. In this embodiment of the application, the device body 2 is also provided with a number of rollers. Each roller is rotatably connected to the device body 2 through a pin, and its bottom is embedded in the movable slide rail 1, so that the device body 2 can move along the extension direction of the movable slide rail 1 through the rollers.

[0041] Reference Figure 1 and Figure 2 In this embodiment, a pipe clamp is also provided on the device body 2. The pipe clamp is fixedly installed on the device body 2 and sleeved on the operating handle 3 for fixing the operating handle 3 to the device body 2. The length direction of the operating handle 3 is perpendicular to the length direction of the sliding rail 1. The first adjusting frame 51 includes a sliding sleeve 511 and a rotating sleeve 512. The sliding sleeve 511 is sleeved on one end of the operating handle 3 and is slidably connected to the operating handle 3, and the sliding direction is the length direction of the operating handle 3.

[0042] Reference Figure 2 and Figure 3 The sliding sleeve 511 has an open end, forming a clamp-like shape. Both ends of the sliding sleeve 511 extending along its own arc are located on the same side, thus forming two fixing protrusions. The first fastening mechanism 6 includes a fastening bolt 61 and a fastening nut 62. One end of the fastening bolt 61 passes through the two fixing protrusions from one side of one fixing protrusion, reaching the other fixing protrusion. The fastening nut 62 is fitted onto the other end of the fastening bolt 61 and is threadedly connected to it. The fastening nut 62 and the fastening bolt 61 abut against the two fixing parts respectively, so that the two fixing parts are tightly abutted, thereby clamping the operating handle 3 with the sliding sleeve 511, thus fixing the sliding sleeve 511 to the operating handle 3.

[0043] Reference Figure 2 and Figure 3The rotating sleeve 512 and the sliding sleeve 511 are rotatably connected by a pin. The rotating sleeve 512 is also equipped with a fixing bolt 53 and a fixing nut 54. One end of the fixing bolt 53 is located on the side of the rotating sleeve 512 away from the sliding sleeve 511, and the other end passes through both the rotating sleeve 512 and the sliding sleeve 511, reaching the end of the sliding sleeve 511 away from the rotating sleeve 512. The fixing nut 54 is fitted onto the end of the fixing bolt 53 and is threadedly connected to it. The end of the fixing bolt 53 abuts against the rotating sleeve 512, and the end of the fixing nut 54 abuts against the rotating sleeve 512, thereby fixing the rotating sleeve 512 and the sliding sleeve 511 by tightening.

[0044] Reference Figure 2 and Figure 3 The rotating sleeve 512 is U-shaped and is fitted onto the top of the second adjusting frame 52, and is slidably connected to the top of the second adjusting frame 52, with the sliding direction being the length direction of the second adjusting frame 52. The second adjusting frame 52 is also equipped with an adjusting assembly 55, which includes an adjusting gear 551, an adjusting rack 552, and an adjusting knob 553. The adjusting rack 552 is fixed to the second adjusting frame 52, and its extension direction is the length direction of the second adjusting frame 52. The adjusting gear 551 is fixedly fitted onto the adjusting knob 553 and meshes with the adjusting rack 552. The adjusting knob 553 is rotatably connected to the rotating sleeve 512 via a bearing.

[0045] Reference Figure 2 and Figure 3 The second fastening mechanism 7 includes a connecting bolt 71 and a connecting nut 72. One end of the connecting bolt 71 is located on one side of the rotating sleeve 512, and the other end passes through both ends of the "U"-shaped rotating sleeve 512 to reach the other side of the rotating sleeve 512. The connecting nut 72 is sleeved on one end of the connecting bolt 71 and is threadedly connected to the connecting bolt 71. The ends of the connecting nut 72 and the connecting bolt 71 away from the connecting nut 72 abut against the two sides of the rotating sleeve 512, so that the rotating sleeve 512 clamps the second adjusting frame 52, thereby fixing the second adjusting frame 52 by friction.

[0046] Reference Figure 2The flame cutting head 4 is fixedly installed at the bottom of the second adjusting frame 52, with its cutting end vertically downwards, to cut the mold steel below. In this embodiment, the bottom of the flame cutting head 4 is provided with a pluggable quick-connect nozzle for easy nozzle replacement. A protective sleeve is also provided on the nozzle, which is fixed to the flame cutting head 4 by a snap-fit ​​connection to protect the nozzle and reduce the probability of the nozzle detaching from the flame cutting head 4. A sensor cap is also fitted on the outside of the protective sleeve, and the sensor cap is fixedly connected to the flame cutting head 4 by a thread. In this embodiment, an infrared ranging sensor is also provided inside the sensor cap. The detection end of the infrared ranging sensor is oriented along the height direction (length direction) of the second adjusting frame 52 to detect the distance between the nozzle and the surface of the mold steel below, and to feed back the detected data to a relevant controller or display for easy access by the operator for adjustment. The nozzle, protective sleeve, sensor cap, and infrared ranging sensor are all prior art, and will not be described in detail here.

[0047] Reference Figure 1 and Figure 2 In this embodiment, the flame cutting head 4 is further connected to a preheating gas pipe, a cutting gas pipe, and a fuel pipe. The fuel pipe is used to introduce fuel gas (such as acetylene, propane, natural gas, etc.) into the flame cutting head 4. The preheating gas pipe is used to introduce oxygen for preheating, so that the oxygen and fuel gas mix in the chamber of the flame cutting head 4 and are then ejected from the nozzle to form a preheated flame. The cutting gas pipe is used to transport high-pressure pure oxygen for cutting, so that the high-pressure pure oxygen is ejected from the nozzle at high speed. The cutting principles of the preheating gas pipe, the cutting gas pipe, the fuel pipe, and the flame cutting head 4 are all prior art, and therefore will not be described in detail here.

[0048] The implementation principle of the high-efficiency cutting device for mold steel in Embodiment 1 of this application is as follows: When it is necessary to adjust the position of the flame cutting head 4, the fastening bolt 61 on the sliding sleeve 511 is first loosened, and then the sliding sleeve 511 is driven to slide, thereby adjusting the position of the sliding sleeve 511 in the length direction of the operating handle 3. After the position of the sliding sleeve 511 is adjusted, the fastening bolt 61 and the fastening nut 62 are tightened, thereby fixing the sliding sleeve 511 and the operating handle 3.

[0049] Next, loosen the connecting bolt 71 and connecting nut 72 on the second adjusting frame 52, and then rotate the adjusting knob 553. This causes the adjusting knob 553 to rotate the adjusting gear 551, which in turn, through the adjusting rack 552, causes the second adjusting frame 52 to slide relative to the rotating sleeve 512, thereby adjusting the height of the second adjusting frame 52 and thus changing the distance between the flame cutting head 4 and the mold steel. After adjustment, tighten the connecting bolt 71 and connecting nut 72 to fix the second adjusting frame 52, completing the adjustment.

[0050] Example 2

[0051] The difference between Embodiment 2 and Embodiment 1 in this application is that: (Refer to...) Figure 4 , Figure 5 and Figure 6 The first adjusting bracket 51 is fitted onto the operating handle 3 and slidably connected to it, with the sliding direction being the length direction of the operating handle 3. An opening is provided at the bottom of the operating handle 3. The end of the first adjusting bracket 51 furthest from the flame cutting head 4 is located within the cavity of the operating handle 3, and an extension portion 513 extends downward from this end. The extension portion 513 extends through the opening at the bottom of the operating handle 3 and is integrally formed with the first adjusting bracket 51. An additional portion 31 also extends downward from the bottom of the operating handle 3. The additional portion 31 is integrally formed with the operating handle 3, located on one side of the extension portion 513, and is abutted against the extension portion 513.

[0052] Reference Figure 4 , Figure 5 , Figure 7 and Figure 8 A fixing groove 311 is also provided through the side wall of the extension part 31, and the extension direction of the fixing groove 311 is the same as the sliding direction of the first adjusting frame 51. The first fastening mechanism 6 includes a fastening bolt 61 and a fastening nut 62. In this embodiment, the number of fastening bolts 61 and fastening nuts 62 is set to two. One end of each fastening bolt 61 (the thread is not shown in the figure) passes through the extension part 513 on the side away from the extension part 31, and passes through the fixing groove 311 on the extension part 31, thereby reaching the side of the extension part 31 away from the fastening nut 62. Each fastening nut 62 is sleeved on the corresponding fastening bolt 61 and threadedly connected to the fastening bolt 61, and is located on the side of the extension part 31 away from the extension part 513, and abuts against the side wall of the extension part 31.

[0053] Reference Figure 5 and Figure 7The extension 513 is also equipped with a fastening handle 63, a drive assembly 64, a rotating sleeve 65, and an intermediate sleeve 66. One end of the fastening handle 63 is rotatably connected to the extension 513 via a pin. The drive assembly 64 includes a drive rod 641 and a drive member 642. The drive member 642 includes a transmission frame 6421 and a sliding frame 6422. There are two transmission frames 6421, located on opposite sides of the fastening handle 63. One end of each transmission frame 6421 is rotatably connected to the fastening handle 63 via a pin, and the other end is inclined downwards and rotatably connected to the sliding frame 6422 via a pin.

[0054] Reference Figure 5 , Figure 7 and Figure 8 The sliding frame 6422 is slidably connected to the extension 513 via a sliding groove, and the sliding direction is perpendicular to the axis of the operating handle 3 (i.e., parallel to the axis of the fastening bolt 61). One end of the sliding frame 6422 extends to the end of the extension 31 away from the extension 513. In this embodiment, the number of drive rods 641, rotating sleeves 65, and intermediate sleeves 66 are all set to two, and each is correspondingly provided to the fastening nut 62. One end of each drive rod 641 is fixedly connected to the side of the sliding frame 6422 away from the fastening handle 63, and each is set as a cylindrical rod, and the axis of each rod is parallel to the axis of the fastening bolt 61.

[0055] Reference Figure 7 and Figure 8 Each drive rod 641 extends towards the extension part 31 at one end, and has two abutment rods 6411 at each end. One end of each abutment rod 6411 is fixedly connected to the corresponding drive rod 641. A rotating sleeve 65 is rotatably connected to the extension part 31 via a bearing, and each rotating sleeve 65 has a circular opening at one end. Each rotating sleeve 65 is fitted onto the corresponding abutment rod 6411, with its inner wall abutting against the outer wall of the abutment rod 6411.

[0056] Reference Figure 7 and Figure 8 Each rotating sleeve 65 has two spiral grooves 651 on its inner wall of the opening, and each spiral groove 651 is spirally arranged along the axis of the rotating sleeve 65. The end of the abutment rod 6411 on each drive rod 641 extends into the corresponding spiral groove 651 and abuts against the inner wall of the spiral groove 651. Each intermediate sleeve 66 has an opening at one end, and each intermediate sleeve 66 has several sliding grooves 661 on its inner wall of the opening, and the extension direction of each sliding groove 661 is the axial direction of the corresponding intermediate sleeve 66.

[0057] Reference Figure 7 and Figure 8Each rotating sleeve 65 has several sliding protrusions 67 on its outer side wall. Each sliding protrusion 67 is integrally formed with the rotating sleeve 65 and is embedded in a corresponding sliding groove 661, abutting against the inner wall of the corresponding sliding groove 661. This allows the intermediate sleeve 66 to slide relative to the corresponding rotating sleeve 65 and rotate together with the rotating sleeve 65. The other end of each intermediate sleeve 66 is fixedly connected to a corresponding fastening nut 62.

[0058] Reference Figure 5 , Figure 7 and Figure 8 In the initial state, when the first adjusting frame 51 is fixed to the operating handle 3, one end of the fastening handle 63 is rotated to the downward position. At this time, the sliding frame 6422 is located on the side of its sliding path away from the fastening handle 63. At this time, the abutment rod 6411 on the drive rod 641 is located on the side of the spiral groove 651 away from the fastening nut 62. At this time, the intermediate sleeve 66 is located on the side of its own moving path close to the extension part 31. At this time, the fastening bolt 61 and the extension part 31 are tightly abutted.

[0059] When the position of the first adjusting frame 51 needs to be adjusted, the drive fastening handle 63 rotates upward, causing the fastening handle 63 to drive the sliding frame 6422 to slide closer to the fastening handle 63 via the transmission frame 6421. During this process, the sliding frame 6422 drives each drive rod 641 to move, causing the abutment rod 6411 on the drive rod 641 to abut against the inner wall of the spiral groove 651 in the corresponding rotating sleeve 65, thereby causing the corresponding rotating sleeve 65 to rotate.

[0060] At this time, the rotating sleeve 65, through the sliding protrusion 67, drives the corresponding intermediate sleeve 66 to rotate together, thereby causing the fastening nut 62 to rotate and gradually move away from the extension part 31. At this time, the intermediate sleeve 66 slides relative to the rotating sleeve 65. After the fastening nut 62 is disengaged from the extension part 31, the first adjusting frame 51 is released from its fixation to the operating handle 3, allowing the operator to adjust the position of the first adjusting frame 51 by sliding it.

[0061] Reference Figure 4 and Figure 5The second adjusting frame 52 is slidably connected to the first adjusting frame 51, and the sliding direction is the height direction of the first adjusting frame 51. The second adjusting frame 52 is also provided with an adjusting assembly 55, which includes an adjusting gear 551, an adjusting rack 552 and an adjusting knob 553. The adjusting gear 551 is rotatably connected to the extension 513 through a pin. The adjusting rack 552 meshes with the adjusting gear 551 and is fixedly connected to the second adjusting frame 52, and is slidably connected to the extension 513, and the sliding direction is parallel to the sliding direction of the second adjusting frame 52.

[0062] Reference Figure 5 and Figure 9 The second fastening mechanism 7 includes an additional plate 73, a connecting pipe 74, and two fastening chucks 75. The connecting pipe 74 is fixedly connected to the adjusting gear 551, and the additional plate 73 is fixedly sleeved on the connecting pipe 74. The two fastening chucks 75 are located on both sides of the additional plate 73, and are both sleeved on the additional plate 73 and are attached to the side wall of the additional plate 73. The two additional plates 73 have grooves on the side that is close to each other, so that the ends of the additional plate 73 can be embedded in them.

[0063] Reference Figure 5 and Figure 9 Each fastening chuck 75 has its bottom rotatably connected to the extension 513 via a pin. The first adjusting frame 51 is also equipped with a transmission mechanism 8, which includes a drive frame 81, a transmission slider 82, and a linkage 83. Two drive frames 81 are provided, each corresponding to one of the fastening chucks 75. One end of each drive frame 81 is rotatably connected to the center of the corresponding fastening chuck 75 via a pin, and the other end is rotatably connected to the transmission slider 82 via a pin. The transmission slider 82 is slidably connected to the extension 513 via a groove, and the sliding direction is the height direction of the extension 513.

[0064] Reference Figure 5 and Figure 9 The transmission slider 82 is slidably connected to the extension 513 via a slide groove, and the sliding direction is the height direction of the extension 513. The linkage 83 includes a linkage frame 831, one end of which is rotatably connected to the sliding frame 6422 via a pin, and the other end is rotatably connected to the transmission slider 82 via a pin. The adjustment knob 553 is fixedly sleeved on the connecting pipe 74 for easy adjustment by the operator.

[0065] Reference Figure 5 , Figure 7 and Figure 9In the initial state, when one end of the fastening handle 63 is facing downwards, and the second adjusting frame 52 is fixed to the first adjusting frame 51, both fastening chucks 75 are fitted onto the additional plate 73, and the sliding frame 6422 is at the top of its sliding path. When the fastening handle 63 rotates upwards, it drives the sliding frame 6422 to slide via the transmission frame 6421. This causes the sliding frame 6422 to drive the transmission slider 82 downwards via the linkage frame 831. Consequently, the transmission slider 82 drives the fastening chuck 75 to rotate via the drive frame 81, gradually releasing the fixation on the additional plate 73.

[0066] The implementation principle of the high-efficiency cutting device for mold steel in Embodiment 2 of this application is as follows: When it is necessary to adjust the position of the flame cutting head 4, the drive fastening handle 63 is rotated upward, thereby causing the fastening handle 63 to drive the sliding frame 6422 to slide closer to the fastening handle 63 via the transmission frame 6421. During this process, the sliding frame 6422 drives each drive rod 641 to move, thereby causing the abutment rod 6411 on the drive rod 641 to abut against the inner wall of the spiral groove 651 in the corresponding rotating sleeve 65, thereby causing the corresponding rotating sleeve 65 to rotate.

[0067] At this time, the rotating sleeve 65, through the sliding protrusion 67, drives the corresponding intermediate sleeve 66 to rotate together, thereby causing the fastening nut 62 to rotate and gradually move away from the extension part 31. At this time, the intermediate sleeve 66 slides relative to the rotating sleeve 65. During this process, the fastening handle 63 drives the sliding frame 6422 to slide through the transmission frame 6421, thereby causing the sliding frame 6422 to drive the transmission slider 82 to slide downward through the linkage frame 831. This causes the transmission slider 82 to drive the fastening chuck 75 to rotate through the drive frame 81, gradually releasing the fixation of the extension plate 73.

[0068] After the fastening nut 62 disengages from the extension part 31, the fastening chuck 75 releases its fixation to the extension plate 73. At this time, the first adjusting bracket 51 is released from its fixation to the operating handle 3, and the second adjusting bracket 52 is released from its fixation to the first adjusting bracket 51. Afterwards, the operator can adjust the position of the flame cutting head 4 by sliding the first adjusting bracket 51 and the second adjusting bracket 52.

[0069] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
