[0001] This utility model relates to the technical field of parts processing equipment, specifically an automatic feeding and cutting auxiliary device for wire EDM equipment. Background Technology

[0002] In modern manufacturing, wire EDM (Electrical Discharge Machining) equipment, as a high-precision machining tool, is widely used in mold making, precision parts processing, and aerospace component production. It primarily utilizes the pulsed discharge phenomenon between the electrode wire and the workpiece to achieve the cutting of conductive materials such as metals.

[0003] Traditional wire EDM equipment relies primarily on lead screws for precise long- and short-distance feed movements during processing. This mechanical transmission method commonly suffers from low processing efficiency and the risk of overtravel due to accumulated errors, thus affecting processing accuracy and production cycle time. Therefore, an automatic feeding and cutting auxiliary device for wire EDM equipment is needed. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feeding and cutting auxiliary device for wire EDM equipment. By setting an automatic feeding mechanism to replace the traditional lead screw drive feeding, the technical problems caused by the reliance on lead screw feeding in traditional wire EDM equipment are avoided, thus solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic feeding and cutting auxiliary device for wire EDM equipment includes a wire EDM machine tool, wherein an automatic feeding mechanism is installed on the upper part of the wire EDM machine tool;

[0007] The automatic feeding mechanism includes a mounting plate installed on the upper part of the online cutting machine tool. Two sets of clamping components for clamping materials are installed on the upper part of the mounting plate. The lower part of one set of clamping components is provided with a guide rail on the upper surface of the mounting plate along the material feeding direction. A slider that slides with the guide rail is installed at the bottom of the clamping component. An adjustable feeding cylinder is installed on the upper part of the mounting plate. When the feeding cylinder is activated, the corresponding clamping component can be driven to slide on the upper part of the guide rail via the slider.

[0009] Preferably, a reference block is installed on the side wall of the fixed frame, and a pressing block for pressing the material is movably installed on the side of the reference block. A pressing cylinder for driving the pressing block to move is installed on the fixed frame through a connecting frame.

[0010] Preferably, a number of guide rods are installed through the middle of the reference block. Each set of guide rods is fitted with a guide sleeve and a first return spring inside the reference block. One end of the first return spring in each set extends to the outside of the reference block and abuts against the side wall of the clamping block.

[0011] Preferably, the reference block has several sets of limiting grooves in the middle, and a stop bar is movably installed inside each set of limiting grooves. Each set of stop bars is elastically connected to the inside of the limiting groove by several sets of second return springs.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides: an automatic feeding and cutting auxiliary device for wire EDM equipment, such as... Figures 1-6 As shown, the system includes a wire EDM machine tool 1, with an automatic feeding mechanism 2 mounted on its upper part. The wire EDM machine tool 1 forms the main frame of the entire wire EDM processing equipment, providing a stable mounting base and working space for the automatic feeding mechanism 2 and other processing-related components. It is the core carrier for realizing wire EDM processing. The automatic feeding mechanism 2, mounted on the upper part of the wire EDM machine tool 1, replaces the traditional lead screw drive to achieve automatic feeding.

[0026] The automatic feeding mechanism 2 includes a mounting plate 3 installed on the upper part of the wire cutting machine tool 1. Two sets of clamping components 4 for clamping materials are mounted on the upper part of the mounting plate 3. One set of clamping components 4 has a guide rail 5 located on the upper surface of the mounting plate 3 along the material feeding direction. A slider 6, which slides along the guide rail 5, is installed at the bottom of the corresponding clamping component 4. An adjustable-length feeding cylinder 7 is mounted on the upper part of the mounting plate 3. When the feeding cylinder 7 is activated, it drives the corresponding clamping component 4 to slide along the guide rail 5 via the slider 6. The mounting plate 3 provides a stable mounting surface for the clamping components 4, guide rail 5, feeding cylinder 7, and other components, ensuring accurate positioning of each component. The movable clamping component 4, connected to the slider 6, is mainly used to move the material under the drive of the feeding cylinder 7; the fixed clamping component 4, directly connected to the mounting plate 3, is used to clamp and fix the material after it reaches its position. The two work together to achieve a seamless material conveying and fixing process, preventing material displacement during feeding and processing and ensuring processing accuracy. The guide rail 5 is mounted on the mounting plate 3 along the material feeding direction. The slider 6 is mounted on the bottom of the movable clamping assembly 4 and slides with the guide rail 5 to form a sliding guide structure, ensuring the accurate movement trajectory of the movable clamping assembly 4 during material feeding. The feeding cylinder 7 is mounted on the upper part of the mounting plate 3 and is the power source for driving the movable clamping assembly 4. When the feeding cylinder 7 is started, its output power pushes the movable clamping assembly 4. The clamping assembly 4 slides smoothly on the guide rail 5 through the slider 6 at the bottom, while moving towards the fixed clamping assembly 4 with the clamped material. When the material enters the clamping range of the fixed clamping assembly 4, the fixed clamping assembly 4 clamps the material, and the movable clamping assembly 4 releases and resets under the drive of the feeding cylinder 7. At this time, the wire EDM machine tool 1 can process the fixed material. This process replaces the traditional lead screw drive, improves feeding efficiency and accuracy, and avoids the risk of overtravel.

[0027] The parameters of the feed cylinder 7 can be selected as follows: cylinder diameter 50mm, stroke 500mm, working pressure 0.4-0.6MPa. The combination of 50mm cylinder diameter and 0.4-0.6MPa working pressure can output a thrust of approximately 314-471N, which can stably drive the movable clamping assembly 4 with slider 6 and the material to slide along the guide rail 5, avoiding feeding jams due to insufficient thrust; the 500mm stroke can cover the single feeding needs of most pipes and metal parts, while reserving sufficient stroke margin to adapt to the feeding needs of materials of different specifications, without the need for frequent cylinder replacement.

[0028] Preferably, the clamping assembly 4 includes a fixing frame 401, wherein one set of fixing frames 401 of the clamping assembly 4 is connected to the mounting plate 3, and the other set of fixing frames 401 of the clamping assembly 4 is connected to the corresponding slider 6. The fixing frame 401 provides mounting support for other components of the clamping assembly 4 and also serves to connect with external components. The fixing frame 401 connected to the mounting plate 3 makes the clamping assembly 4 a fixed clamping assembly, ensuring that it remains fixed during material processing and reliably clamps the material through the stable support of the fixing frame 401; the fixing frame 401 connected to the slider 6 makes the clamping assembly 4 a movable clamping assembly, which can slide synchronously with the slider 6 along the guide rail 5 to realize the material conveying function.

[0029] Preferably, a reference block 402 is mounted on the side wall of the fixed frame 401, and a clamping block 403 for pressing the material is movably mounted on the side of the reference block 402. A clamping cylinder 405 for driving the clamping block 403 to move is mounted on the fixed frame 401 via a connecting frame 404. The reference block 402 provides a positioning reference for the material, ensuring that the material is placed in a consistent position whether it is being conveyed by the movable clamping assembly or positioned by the fixed clamping assembly, which is the basis for ensuring clamping accuracy. The main function of the clamping block 403 is to cooperate with the reference block 402 to clamp the material. It achieves the pressing and releasing of the material through its own movement. In the movable clamping assembly, it is used to clamp the material to be conveyed, and in the fixed clamping assembly, it is used to clamp the material for processing. The connecting frame 404 is used to fix the clamping cylinder 405, so that the clamping cylinder 405 can output power stably and provide the clamping block 403 with the force required to clamp the material. In the movable and fixed clamping assemblies, the clamping block 403 is driven to complete the conveying clamping and processing clamping actions respectively. When the movable clamping assembly conveys material, the material is placed on one side of its reference block 402. The clamping cylinder 405 of the assembly is activated, and the piston rod extends to push the clamping block 403 to move along the side of the reference block 402, clamping the material between the reference block 402 and the clamping block 403. The material moves with the movable clamping assembly toward the fixed clamping assembly. When the material enters the reference block 402 side of the fixed clamping assembly, the clamping cylinder 405 of the fixed clamping assembly is activated, pushing its clamping block 403 to clamp the material. Subsequently, the clamping cylinder 405 of the movable clamping assembly is depressurized, the piston rod retracts, and the clamping block 403 is reset, releasing the material. This completes the switch from material conveying clamping to processing clamping, facilitating subsequent wire cutting processing operations.

[0030] The clamping cylinder 405 can be configured with a cylinder diameter of 32mm, a stroke of 20mm, a working pressure of 0.3-0.5MPa, and a buffer device. The 32mm cylinder diameter and 0.3-0.5MPa working pressure can output a clamping force of approximately 75-126N, which can stably clamp the material to one side of the reference block 402 via the clamping block 403 without causing material deformation due to excessive clamping force. The 20mm stroke can meet the clamping gap requirements of most materials. The buffer device can reduce the impact force when the clamping block 403 contacts the material, further protecting the material surface from scratches.

[0031] Furthermore, several sets of guide rods 406 are installed through the center of the reference block 402. Each set of guide rods 406 has a guide sleeve 408 and a first return spring 409 fitted inside the reference block 402. One end of each first return spring 409 extends to the outside of the reference block 402 and abuts against the side wall of the clamping block 403. The main function of the guide rods 406 is to guide the movement of the clamping block 403, ensuring that the clamping block 403 always moves in the set direction, avoiding deviation that affects clamping accuracy. The guide sleeve 408 is fitted outside the guide rods 406 and located inside the reference block 402, reducing friction between the guide rods 406 and the reference block 402. The first return spring 409 is fitted outside the guide rods 406, with one end abutting against the side wall of the clamping block 403 and the other end fixed inside the reference block 402. Its main function is to assist the clamping block 403 in resetting; it also acts as a buffer during the clamping process, preventing the clamping block 403 from causing excessive compression damage to the material. When the clamping cylinder 405 of the movable clamping assembly drives the clamping block 403 to move towards the material, it compresses the first return spring 409 to clamp the material. When the material is conveyed to the fixed clamping assembly and clamped by it, the clamping cylinder 405 of the movable clamping assembly is depressurized, the first return spring 409 releases its elastic potential energy, and pushes the clamping block 403 to move in the opposite direction to reset.

[0032] Furthermore, the reference block 402 has several sets of limiting grooves 410 in its center. Each limiting groove 410 has a stop bar 411 movably installed inside it. Each stop bar 411 is elastically connected to the limiting groove 410 via several sets of second return springs 412. The limiting groove 410 provides installation space for the stop bar 411 and the second return springs 412, while also limiting the range of movement of the stop bar 411. The main function of the stop bar 411 is to initially limit the material placement, preventing excessive deviation in the material's position. The main function of the second return springs 412 is to provide elastic support for the stop bar 411, allowing it to retract into the limiting groove 410 when squeezed by the material. When the clamping assembly places the material, the material pushes the stop bar 411, which compresses the second return spring 412 and retracts into the limiting groove 410 until the material adheres to the reference block 402 and completes the initial positioning. After the material is processed and removed, the second return springs 412 of both clamping assemblies return to their original state, pushing their respective stop bars 411 out of the limiting groove 410 and returning to the initial limiting position.

[0033] It is worth noting that a material handling mechanism 8 is installed on the side of the wire EDM machine tool 1, corresponding to the automatic feeding mechanism 2. The material handling mechanism 8 includes a height-adjustable support frame 9. The main function of the material handling mechanism 8 is to store the materials to be processed, achieving orderly placement of the materials. The support frame 9 provides mounting support for other components of the material handling mechanism 8. Its height-adjustable design can adapt to the placement requirements of materials of different specifications, while ensuring that the height of the material handling mechanism 8 matches that of the movable clamping component 4 of the automatic feeding mechanism 2, ensuring that the materials can smoothly enter the clamping range of the movable clamping component 4.

[0034] Specifically, the upper part of the support frame 9 is equipped with several sets of rotatable rollers 10. A connecting plate 11, which connects to the wire EDM machine tool 1, is mounted on the upper part of the rollers 10. Several sets of material rack assemblies 12 are arranged on the upper part of the connecting plate 11. The main function of the rollers 10 is to provide support for the connecting plate 11 and reduce the frictional resistance when the connecting plate 11 moves. The connecting plate 11, mounted on the upper part of the rollers 10 and connected to the wire EDM machine tool 1, provides a stable mounting surface for the material rack assemblies 12, ensuring that the material rack assemblies 12 are fixed in position. The main function of the material rack assemblies 12 is to limit the placement of materials, ensuring that the materials can be synchronously and orderly conveyed to the movable clamping assembly 4 along with the connecting plate 11.

[0035] More specifically, the material rack assembly 12 includes baffles 1201 fixed to the upper surface of the connecting plate 11. Each baffle 1201 has a groove 1202 on its side located in the middle of the connecting plate 11. A stop block 1203, which cooperates with the baffle 1201 to limit the material movement, is slidably installed inside each groove 1202. The baffle 1201 is a fixed limiting component of the material rack assembly 12, capable of blocking and limiting one side of the material to prevent it from sliding off the side of the connecting plate 11. The groove 1202 provides a sliding track for the stop block 1203, allowing the stop block 1203 to move along the groove 1202, adjusting the distance between it and the baffle 1201 to accommodate materials of different specifications. This ensures that materials of different sizes can be stably placed on the connecting plate 11, preventing material displacement due to size mismatch. The stop block 1203 is slidably installed inside the slide groove 1202 and works in conjunction with the baffle 1201. By adjusting the position of the stop block 1203 in the slide groove 1202, the distance between the two can be changed to adapt to materials of different diameters or widths, thereby achieving precise positioning of the materials and ensuring that the materials are placed in a uniform position on the connecting plate 11, which is convenient for the movable clamping component 4 to accurately grasp them.
