Description

Technical Field

[0001] This invention relates to the field of tungsten carbide mold hole system processing technology, specifically to an edge grooving device for tungsten carbide mold hole system processing. Background Technology

[0002] Steel mold hole system machining refers to a specialized process for high-precision and high-consistency collaborative machining of multiple holes (such as deep holes, micro holes, intersecting holes, and array holes) on tungsten carbide-based cemented carbide molds. The core objective is to achieve micron-level control over hole diameter, positional accuracy, coaxiality, and inner wall surface finish. It is widely used in the manufacturing of key components such as wire drawing dies, stamping dies, and semiconductor packaging dies.

[0003] Conventional grooving devices for machining hole systems in tungsten carbide molds mostly employ a single-axis drive structure, achieving grooving through linear motion in a single direction combined with manual positioning. This traditional device suffers from three technical drawbacks: First, positioning accuracy is limited by the operator's skill level, making it difficult to meet micron-level machining requirements; second, in single-axis drive mode, the trimming component requires frequent start-stop adjustments, accelerating wear on mechanical parts; and third, it lacks automated collaborative control, requiring manual adjustment of parameters such as grooving depth and width, which cannot guarantee consistency in machining multiple holes. Summary of the Invention

[0004] The purpose of this invention is to provide an edge grooving device for machining hole systems in tungsten carbide molds, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an edge grooving device for machining hole systems in tungsten steel molds, comprising a first drive crossbeam and a trimming component. A second drive crossbeam is horizontally connected and installed on one side surface of the first drive crossbeam. The second drive crossbeam is connected and installed at the bottom of the trimming component. A drive stand and an auxiliary support are vertically connected and installed at the left and right ends of the first drive crossbeam, respectively. The trimming component includes a moving table, an electric rotary seat, an electric joint, a stabilizer, a direct drive motor, and a cutting tool. An electric rotary seat is installed at the bottom of the moving table, and an electric joint is connected to the bottom of the electric rotary seat. A stabilizer is connected and installed at the end of the electric joint away from the electric rotary seat, and a direct drive motor is vertically installed in the middle of the stabilizer. A cutting tool is connected and installed at the bottom power output end of the direct drive motor via a coupling.

[0006] Furthermore, the first drive crossbeam includes a first crossbeam, a first guide rail, a first transmission screw, a first servo motor, a docking frame, a first movable seat, and a second movable seat. The first guide rail is horizontally mounted on the top of the first crossbeam, and the first transmission screw is horizontally mounted on the top of the first guide rail. One end of the first transmission screw is horizontally connected to and mounted with the first servo motor via a coupling. The left and right ends of the first crossbeam are both equipped with docking frames, and the left and right ends of the first crossbeam are connected to and mounted with the first movable seat and the second movable seat via the docking frames.

[0007] Furthermore, the second drive crossbeam includes a second crossbeam, a second guide rail, a second transmission screw, a second servo motor, and a third movable seat. The second guide rail is horizontally mounted on the bottom surface of the second crossbeam, and the second transmission screw is horizontally arranged directly below the second guide rail. One end of the second transmission screw is connected to the second servo motor through a coupling, and the third movable seat is mounted on the end of the second crossbeam close to the first drive crossbeam.

[0008] Furthermore, the third movable seat is connected to the first guide rail and the first transmission screw in a slotted embedded structure and a threaded connection, and the second crossbeam and the third movable seat are fixedly connected. The movable table is connected to the second guide rail and the second transmission screw in a slotted embedded structure and a threaded connection.

[0009] Furthermore, the first drive crossbeam and the second drive crossbeam are connected in a "T"-shaped structure, and the first drive crossbeam provides the second drive crossbeam and the trimming component with the horizontal X-axis direction of movement, while the second drive crossbeam provides the trimming component with the horizontal Y-axis direction of movement.

[0010] Furthermore, the drive frame includes a first frame, a drive motor, a drive screw, a first slide rail, and a first fixed corner bracket. The drive motor is vertically mounted on the top of the first frame near the side of the first drive crossbeam, and the drive screw is vertically connected to the bottom power output end of the drive motor via a coupling. The first slide rail is vertically mounted on the surface of the first frame near the drive screw, and the three sides of the bottom of the first frame are all mounted on the first fixed corner bracket.

[0011] Furthermore, the auxiliary support includes a second upright, a second slide rail, and a second fixed corner bracket. The second slide rail is vertically mounted on the side surface of the second upright near the first drive crossbeam, and the second fixed corner bracket is mounted on each of the three sides at the bottom of the second upright.

[0012] Furthermore, the first movable seat, the drive screw, and the first slide rail are respectively connected by a threaded connection and a slotted embedded structure, and the second movable seat and the second slide rail are connected by a slotted embedded structure.

[0013] This invention provides an edge grooving device for machining hole systems in tungsten carbide molds, which has the following advantages: 1. This invention, through the structural design of the modified component, specifically the combination of an electric rotary base and an electric joint, enables the cutting tool to be flexibly adjusted at multiple angles, meeting the machining requirements of complex curved surfaces on the edges of tungsten carbide mold holes. The direct-drive motor directly drives the cutting tool via a coupling, avoiding mechanical backlash in traditional transmission structures and significantly improving cutting accuracy and surface quality. The stabilizer is made of high-rigidity material, effectively suppressing vibration during the cutting process and ensuring machining stability.

[0014] 2. This invention, through the structural arrangement between the first and second drive crossbeams, wherein the first and second drive crossbeams are connected in a "T" shape, provides X and Y dual-axis horizontal movement drive for the trimming component. This layout enables the trimming component to achieve precise two-dimensional positioning in a plane. Combined with the multi-angle adjustment capability of the trimming component itself, it can complete high-precision grooving operations on complex curved surfaces of tungsten steel mold hole systems. The first drive crossbeam drives the first transmission screw through a first servo motor, causing the first and second moving seats to move along the first guide rail; the second drive crossbeam drives the second transmission screw through a second servo motor, causing the third moving seat to move along the second guide rail, thereby achieving precise position control of the trimming component in the horizontal plane.

[0015] 3. This invention, through the structural arrangement between the drive frame and the auxiliary support, allows the drive frame to rotate via a drive motor-driven lead screw. Combined with the guiding effect of the first slide rail, this enables the first moving seat to move precisely in the vertical direction. The design of the first fixed corner seat enhances the stability of the drive frame, ensuring that displacement errors do not occur due to vibration during processing. The auxiliary support provides vertical support and guidance for the second moving seat via a second slide rail, while the second fixed corner seat further enhances the rigidity of the overall structure. This dual-support design enables the trimming component to have precise positioning capabilities in three-dimensional space, meeting the stringent spatial accuracy requirements for grooving the edge of tungsten carbide mold holes. The coordinated work of the drive frame and the auxiliary support, along with the horizontal movement of the first and second drive crossbeams, achieves full-position coverage of the trimming component within the processing area, significantly improving the processing flexibility and applicability of the device.

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] like Figures 1 to 6As shown, an edge grooving device for machining hole systems in tungsten steel molds includes a first drive crossbeam 1 and a trimming component 3. A second drive crossbeam 2 is horizontally connected and installed on one side surface of the first drive crossbeam 1. The second drive crossbeam 2 is connected and installed at the bottom of the trimming component 3. A drive stand 4 and an auxiliary support 5 are vertically connected and installed at the left and right ends of the first drive crossbeam 1, respectively. The trimming component 3 includes a moving table 301, an electric rotary seat 302, an electric joint 303, a stabilizer 304, a direct drive motor 305, and a cutting tool 306. The bottom of the moving table 301... The part is equipped with an electric rotary base 302, and an electric joint 303 is connected to the bottom of the electric rotary base 302. A stabilizer 304 is connected to the end of the electric joint 303 away from the electric rotary base 302, and a direct drive motor 305 is vertically mounted in the middle of the stabilizer 304. A cutting tool 306 is connected to the power output end of the direct drive motor 305 via a coupling. The combined design of the electric joint 303 and the electric rotary base 302 allows the cutting tool 306 to achieve flexible angle adjustment in three-dimensional space. The electric rotary base 302 provides rotational freedom about a vertical axis, while the electric joint 303 provides oscillating freedom in two mutually perpendicular directions. The coordinated operation of these three components can meet the machining requirements of complex curved surfaces at the edges of tungsten carbide mold holes. The direct drive motor 305 directly drives the cutting tool 306 via the coupling. This transmission method eliminates the mechanical backlash in traditional gear or belt drives, significantly improving cutting accuracy and surface quality. The stabilizer 304 is made of high-rigidity alloy material and has an internal vibration damping structure, which can effectively suppress vibrations during the cutting process and ensure machining stability. The moving table 301 serves as the base of the dressing component 3 and achieves precise horizontal movement through its connection with the second drive crossbeam 2. In actual machining, the operator can set the rotation angle of the electric rotary table 302 and the electric joint 303, as well as the speed and cutting depth of the direct drive motor 305, according to the dimensional parameters of the mold hole system, thereby achieving high-precision edge grooving operations.

[0020] like Figures 1 to 6As shown, the first drive crossbeam 1 includes a first crossbeam 101, a first guide rail 102, a first transmission screw 103, a first servo motor 104, a docking frame 105, a first movable seat 106, and a second movable seat 107. The first guide rail 102 is horizontally mounted on the top of the first crossbeam 101, and the first transmission screw 103 is horizontally mounted on the top of the first guide rail 102. One end of the first transmission screw 103 is horizontally connected to the first servo motor 104 via a coupling. The left side of the first crossbeam 101... Both ends of the first crossbeam 101 are equipped with docking brackets 105, and the left and right ends of the first crossbeam 101 are connected and installed with a first movable seat 106 and a second movable seat 107 via docking brackets 105. The second drive crossbeam 2 includes a second crossbeam 201, a second guide rail 202, a second transmission screw 203, a second servo motor 204, and a third movable seat 205. The bottom surface of the second crossbeam 201 is horizontally equipped with the second guide rail 202, and the second transmission screw 203 is horizontally arranged directly below the second guide rail 202. One end of the transmission screw 203 is connected to the second servo motor 204 via a coupling. A third movable seat 205 is installed on the end of the second crossbeam 201 near the first drive crossbeam 1. The third movable seat 205 is connected to the first guide rail 102 and the first transmission screw 103 in a slotted embedded structure and by thread. The second crossbeam 201 and the third movable seat 205 are fixedly connected. The movable table 301 is connected to the second guide rail 202 and the second transmission screw 203 in a slotted embedded structure and by thread. The first drive crossbeam 1 and the second drive crossbeam 2 are connected in a "T"-shaped structure. The first drive crossbeam 1 provides the second drive crossbeam 2 and the trimming component 3 with horizontal X-axis movement drive, and the second drive crossbeam 2 provides the trimming component 3 with horizontal Y-axis movement drive. The "T"-shaped structure of the first drive crossbeam 1 and the second drive crossbeam 2 enables the trimming component 3 to achieve precise two-dimensional positioning in the horizontal plane. The first drive crossbeam 1 drives the first transmission screw 103 to rotate via the first servo motor 104. The threaded connection between the first transmission screw 103 and the first movable seat 106 and the second movable seat 107 converts the rotational motion into linear motion, causing the first movable seat 106 and the second movable seat 107 to move along the first guide rail 102. The second drive crossbeam 2 drives the second transmission screw 203 to rotate via the second servo motor 204. The threaded connection between the second transmission screw 203 and the third movable seat 205 also converts the rotational motion into linear motion, causing the third movable seat 205 to move along the second guide rail 202. Because the third movable seat 205 is connected to the first guide rail 102 and the first transmission screw 103 of the first drive crossbeam 1 via a slotted embedded structure, it ensures that the second drive crossbeam 2 moves synchronously with the first drive crossbeam 1 in the horizontal X-axis direction. At the same time, the movement of the second drive crossbeam 2 itself provides the trimming component 3 with the driving force for movement in the horizontal Y-axis direction.This dual-axis drive design allows the trimming component 3 to cover a larger processing area, meeting the grooving requirements of the edges of tungsten carbide mold holes of different sizes. In actual operation, the operator can set the speed and direction of the first servo motor 104 and the second servo motor 204 respectively through the control system to precisely control the position of the trimming component 3 in the horizontal plane, achieving high-precision machining of complex curved surfaces.

[0021] like Figures 1 to 6 As shown, the drive frame 4 includes a first frame 401, a drive motor 402, a drive screw 403, a first slide rail 404, and a first fixed corner bracket 405. The drive motor 402 is vertically mounted on the top of the first frame 401 near the first drive crossbeam 1. The drive screw 403 is vertically connected to the bottom power output end of the drive motor 402 via a coupling. The first slide rail 404 is vertically mounted on the surface of the first frame 401 near the drive screw 403. The three sides of the bottom of the first frame 401 are all mounted on the first fixed corner bracket 405. The frame 5 includes a second upright 501, a second slide rail 502, and a second fixed corner bracket 503. The second slide rail 502 is vertically mounted on the surface of the second upright 501 near the first drive crossbeam 1, and the second fixed corner bracket 503 is mounted on each of the three sides of the bottom of the second upright 501. The first movable seat 106, the drive screw 403, and the first slide rail 404 are connected to each other by threaded connections and slotted embedded structures, respectively. The second movable seat 107 and the second slide rail 502 are connected to each other by slotted embedded structures. The drive upright 4 and the auxiliary support 5 are coordinated. The same design enables precise vertical control of the trimming component 3; in the drive frame 4, the drive motor 402 drives the drive screw 403 to rotate, and drives the first moving seat 106 to move up and down along the first slide rail 404 through a threaded connection. The first fixed angle seat 405 enhances the overall rigidity through a three-point support structure, effectively suppressing vibration during processing; the auxiliary support 5 provides vertical guidance for the second moving seat 107 through the second slide rail 502, and the second fixed angle seat 503 further improves the structural stability, ensuring the smooth operation of the second moving seat 107 in the vertical direction; this The dual-support layout enables the trimming component 3 to have precise positioning capabilities in three-dimensional space. Combined with the horizontal movement of the first drive crossbeam 1 and the second drive crossbeam 2, it achieves full-position coverage within the processing area. In actual operation, the operator can synchronously adjust the speed and direction of the drive motor 402 through the control system to precisely control the vertical position of the trimming component 3, meeting the requirements for grooving at different depths on the edges of the tungsten steel mold hole system. At the same time, the rigid connection design between the drive stand 4 and the auxiliary support 5 effectively avoids structural deformation caused by uneven stress during processing, ensuring long-term stability.

[0022] In summary, as Figures 1 to 6As shown, the edge grooving device for machining the hole system of tungsten carbide molds is used by first fixing the tungsten carbide mold to be processed on the worktable, ensuring that the edge of the mold hole system is within the processing area of ​​the device; the control system starts the first servo motor 104 of the first drive crossbeam 1, drives the first transmission screw 103 to rotate, and drives the first moving seat 106 and the second moving seat 107 to move along the first guide rail 102, so that the trimming component 3 is close to the edge of the mold hole system in the horizontal X-axis direction; then, the second servo motor 204 of the second drive crossbeam 2 starts, drives the second transmission screw 203 to rotate, and drives the third moving seat 205 to move along the second guide rail 202, so that the trimming component 3 is precisely aligned with the processing position in the horizontal Y-axis direction; Based on the complex curved surface shape of the mold hole system edge, the rotation angle of the electric rotary seat 302 and the electric joint 303 is set by the control system to adjust the cutting tool 306 to a suitable machining angle; at the same time, the speed and cutting depth of the direct drive motor 305 are set to ensure that the cutting tool 306 performs machining with optimal parameters; the drive motor 402 of the drive stand 4 is started, which drives the drive screw 403 to rotate, driving the first moving seat 106 to move up and down along the first slide rail 404, so that the trimming component 3 approaches the edge of the mold hole system in the vertical direction; the second slide rail 502 of the auxiliary support 5 provides vertical guidance for the second moving seat 107 to ensure the smooth operation of the trimming component 3 in the vertical direction; During the processing, the vibration damping structure of the stabilizer 304 effectively suppresses cutting vibration and ensures processing stability. The operator can monitor the processing status in real time through the control system and adjust the parameters of each drive component as needed to ensure high-precision completion of the grooving operation on the edge of the tungsten carbide mold hole system. After processing, the drive components are turned off, the trimming component 3 is moved to a safe position, the processed tungsten carbide mold is taken out, and the entire processing process is completed.
