Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for wire electrical discharge machining, and more specifically to a wire-cut molybdenum wire cutting and recycling device. Background Technology

[0002] Wire EDM machining is a process that utilizes the electro-corrosion effect of pulsed discharge between a motor wire (the negative electrode) and the metal workpiece (the whole machine) to process the workpiece. It is mainly used for manufacturing various molds, electrodes, precision parts, and machining complex cavities and curved surfaces of various conductive materials such as cemented carbide, hardened steel, graphite, aluminum alloy, structural steel, stainless steel, titanium alloy, and diamond. The wire EDM molybdenum wire cutting and recycling device is an auxiliary device for the wire EDM machine, designed to efficiently handle waste molybdenum wire generated during processing. Several situations can lead to accidental breakage of the molybdenum wire during processing, such as: excessive partial discharge burning out the wire; hard impurities in the workpiece material causing severe friction during cutting; or insufficient or contaminated coolant leading to poor chip removal and concentrated arc discharge.

[0003] Insufficient technology: When molybdenum wire breaks accidentally during processing, waste wire needs to be cleaned up. When the remaining part of the molybdenum wire is still relatively new and has little wear, it is not necessary to recycle all the molybdenum wire. However, the current technology for processing and recycling waste molybdenum wire usually involves stopping the machine tool and then using scissors or related tools to cut the broken molybdenum wire from both ends of the broken area. The molybdenum wire is then pulled out and cut for recycling, which is inefficient. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wire cutting molybdenum wire cutting and recycling device to solve the problems existing in the background art.

The shape of the pressure rod 2 and the pressure block 2 matches the shape of the pressure groove 2.

[0013] Furthermore, the elastic rod of the limiting rod is in contact with the cutting plate in the vertical state.

[0014] Furthermore, the cutting assembly includes a tangent plate fixedly connected to a fixing frame one.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. This invention features a cutting and recycling mechanism, comprising a fixed frame one fixedly connected to the side of the wire frame, and a wire wheel one, a cutting assembly, a wire wheel two, an elastic wheel, a transmission assembly, and a lever assembly disposed inside the fixed frame one. The elastic wheel detects the breakage of the molybdenum wire and converts it into a simple mechanical action. The transmission assembly and lever assembly transmit this mechanical action to the wire wheels one and two, triggering them to press and fix the molybdenum wire. Subsequently, the cutting assembly is triggered to cut the molybdenum wire. Finally, the wire wheel two completes the winding and recycling of the waste molybdenum wire, preventing broken waste molybdenum wire from scattering inside the machine tool and causing short circuits or mechanical failures. This facilitates the efficient processing of waste molybdenum wire during processing and improves processing efficiency.

[0019] 2. This invention features a second wire reel, including a power motor, a fixed sleeve fixedly connected to the motor shaft of the power motor, and a second movable wheel fixedly connected to one side of the fixed sleeve. A second spring is fixedly connected to the top end of the fixed sleeve, and a pressing and cutting assembly is fixedly connected to the top end of the second spring. The power motor drives the second movable wheel to achieve winding, and the pressing and cutting assembly achieves the pressing, cutting, and recycling of the molybdenum wire. This invention integrates the pressing, winding, and recycling of the molybdenum wire onto the second wire reel, which is beneficial to further improve processing efficiency.

[0020] 3. The present invention features an elastic wheel. Under normal conditions, due to the tension of the molybdenum wire, the thread guide wheel of the elastic wheel stretches the spring three upward. When the molybdenum wire breaks, the contraction force of the spring three causes the toothed rod one to move downward, and triggers the clamping action of the thread wheel one and thread wheel two through the lever assembly, thus timely and effectively fixing the broken molybdenum wire. This is beneficial to improving the reaction efficiency of the corresponding components after the molybdenum wire breaks, thereby improving the processing efficiency. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The wire cutting molybdenum wire cutting and recycling device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 1 , Figure 3 and Figure 8 This invention provides a wire cutting molybdenum wire cutting and recycling device, including a worktable 1. From left to right, a wire spool 2, a wire guide 3, and a coordinate worktable 4 are sequentially arranged on the top of the worktable 1. The side of the wire guide 3 is sequentially fixedly connected to a guide wheel 301, a guide plate 302, a cutting and recycling mechanism 5, and a guide wheel 303. The molybdenum wire can be drawn from the wire spool 2, passing over the wire groove 401 located in the middle of the coordinate worktable 4 and the guide wheel 303 above the wire groove 401, and then sequentially passing through the cutting and recycling mechanism 5. The guide plate 302 and guide wheel 301 return to the wire drum 2 to complete the wire feeding. The cutting and recycling mechanism 5 includes a fixed frame 501 fixedly connected to the side of the wire frame 3 and a wire wheel 502, a cutting assembly 503, a wire wheel 504, an elastic wheel 505, a transmission assembly 506, and a lever assembly 507 disposed inside the fixed frame 501. When feeding the wire, the molybdenum wire passes under the elastic wheel 505, and then passes over the wire wheel 504, inside the cutting assembly 503, and over the wire wheel 502.

[0036] The second spool 504 includes a power motor 5041, a fixed sleeve 5043 fixedly connected to the motor shaft of the power motor 5041, and a movable wheel 5042 fixedly connected to the periphery of the fixed sleeve 5043. A spring 5044 is fixedly connected to one top end of the fixed sleeve 5043, and a pressing and cutting assembly 508 is fixedly connected to the top end of the spring 5044. The outer peripheral surface of the movable wheel 5042 is provided with an annular wire-passing groove 5045 and a wire-pressing groove 5046 perpendicular to the wire-passing groove 5045.

[0037] The molybdenum wire passes through the wire groove 5045 on the side of the movable wheel 5042. When the workpiece is cut, that is, when the molybdenum wire breaks in the area between the guide wheel 303 and the wire groove 401, the clamping and cutting assembly 508 quickly clamps the broken molybdenum wire. After the cutting assembly 503 cuts it, the power motor 5041 drives the motor shaft to rotate, which drives the fixed sleeve 5043 and the movable wheel 5042 to rotate and perform a winding action. After winding is completed, the waste molybdenum wire is cut and recycled by the clamping and cutting assembly 508.

[0038] Reference Figure 2The fixing bracket 501 is fixedly connected to the side of the conductor frame 3 by the corner bracket 5012 set at the bottom end. The fixing bracket 501 has a fixing hole 5011 on its side. The inside of the fixing hole 5011 is fixedly connected to the side of the power motor 5041. One end of the motor shaft of the power motor 5041 is movably connected to the inner wall of the fixing bracket 501.

[0039] Reference Figures 3 to 5 A fixed bracket 5051 is fixedly connected to the top right of the fixed bracket 501. A long rod 5052 is symmetrically arranged at the top of the fixed bracket 5051. A short shaft 5053 is fixedly connected to the bottom of the long rod 5052. A wire guide wheel 5054 is movably connected to the middle of the short shaft 5053. A wire guide groove 5055 is opened on the outer edge of the wire guide wheel 5054. The long rod 5052 passes through the fixed bracket 5051 and a top plate 5056 is fixedly connected to its top. A spring 5057 is sleeved on the long rod 5052 from the fixed bracket 5051 to the top plate 5056. The bottom of the spring 5057 is fixedly connected to the top of the fixed bracket 5051 and its top is fixedly connected to the bottom of the top plate 5056. In addition, a toothed rod 5059 is fixedly connected to one side of the top plate 5056 through a connecting plate 5058.

[0040] After the molybdenum wire is fed, it passes under the wire guide wheel 5054 and cuts into the wire guide groove 5055 on its outer edge. When the molybdenum wire is tightened, it will give the wire guide wheel 5054 an upward force, causing the long rod 5052 to rise relative to the fixed bracket 5051, and causing the spring 5057 to deform and be stretched. At the same time, the top plate 5056 and the connecting plate 5058 will drive the rack 5059 to rise. When the wire guide wheel 5054 loses the upward force, the spring 5057 will recover its deformation, giving the top plate 5056 and the connecting plate 5058 a downward force, causing the rack 5059 to move downward.

[0041] Reference Figure 6 and Figure 7 The side of the rack 5059 is meshed with a gear 5062, and the middle of the gear 5062 is movably connected to a round rod 5063. The round rod 5063 is fixedly connected to the top of the bracket 501 by a fixing post 5061 fixed at one end.

[0042] Among them, the edge of gear 5062 is meshed with rack 5071, and a connecting rod 5072 is fixedly connected to one side of the bottom end of rack 5071. Two branch rods 5073 are spaced apart at the bottom end of the connecting rod 5072. A fixing sleeve 5074 is fixedly connected to one side of the bottom end of branch rod 5073. A connecting rod 5075 is fixedly connected inside the fixing sleeve 5074. A locking rod 5076 is fixedly connected to one end of the two connecting rods 5075. A fixing plate 5077 is movably connected to the side of branch rod 5073. A spring 5078 is fixedly connected to the top of fixing plate 5077. The top of spring 5078 is fixedly connected to the bottom end of connecting rod 5072. Fixing plate 5077 is fixedly connected to the top of fixing frame 501 through a vertical plate 5013 fixedly connected to one end.

[0043] When rack 1 5059 moves downward, rack 2 5071 moves upward through gear 5062, and drives two branch rods 5073 and their commonly fixed connecting rod 5076 to move upward through connecting rod 5072. During this process, spring 4 5078 releases its initial compression and elastic force, allowing connecting rod 5072 to be lifted more easily. In addition, the end of fixing plate 5077 is provided with a vertical slot for fixing branch rods 5073 and for making branch rods 5073 move only up and down. Conversely, when rack 1 5059 moves upward, connecting rod 5076 moves downward.

[0044] Among them, the top end of the fixed plate 5077 is fixedly connected to the limiting rod 5079. The limiting rod 5079 includes a short column fixedly connected to the top end of the fixed plate 5077 and an elastic rod fixedly connected to one side of the short column. The elastic rod is located between the two fixed plates 5077.

[0045] Reference Figure 8 and Figure 9 The pressing and cutting assembly 508 includes a support rod 5081 fixedly connected to the top of the fixed sleeve 5043 and a round shaft 5082 fixedly connected to the top of the support rod 5081. The side of the round shaft 5082 is movably connected to a rotating sleeve 5083 and a rotating sleeve 5086. The outer edge of the rotating sleeve 5083 is provided with a cutting plate 5084 along the tangential direction. The side of the cutting plate 5084 is provided with a cutting blade 5085. The side of the rotating sleeve 5086 is fixedly connected with a pressure rod 5087 along the axial direction. One end of the pressure rod 5087 is enlarged and has a slot that can engage with the clamping rod 5076. The bottom end of the pressure rod 5087 is provided with a pressure block 5088, and the top end of the pressure rod 5087 has a cutting groove 5089. The pressure rod 5087 and the pressure block 5088 fit the shape of the pressure groove 5046.

[0046] The cutting plate 5084 is usually in a vertical position, and is maintained in a vertical position with the assistance of the limiting rod 5079 (see reference). Figure 3 ); The second pressure rod 5087 is usually in an inclined state. In this state, the second spring 5044 is in a stretched state. At this time, the second pressure rod 5087 and the horizontal plane where the first fixing sleeve 5043 is located form a 40° angle, and its end slot engages with the locking rod 5076.

[0047] When an abnormal condition (referring to molybdenum wire breakage) occurs, the clamping rod 5076 moves upward and separates from the pressure rod 5087. The pressure rod 5087 moves downward rapidly under the contraction force of the spring 5044 and engages with the pressure groove 5046, thereby pressing the molybdenum wire on one side of the workpiece cutting area.

[0048] Reference Figure 11 The cutting assembly 503 includes a cutting plate 5031 fixedly connected to a fixing frame 501. The top of the cutting plate 5031 is provided with a cutting groove 5032, and a fixing frame 5033 is fixedly connected to one side of the cutting plate 5031. A hydraulic cylinder 5034 and a telescopic rod 5035 are fixedly connected to the top of the inner part of the fixing frame 5033. A knife holder 5036 is fixedly connected to the bottom of the telescopic rod 5035, and a cutter 5037 is fixedly connected to the bottom of the knife holder 5036. The cutter 5037 is located above the cutting groove 5032, and the plane of its blade is in the same plane as the long axis of the cutting groove 5032.

[0049] The hydraulic cylinder 5034 drives the telescopic rod 5035 to move up and down, thereby controlling the up and down movement of the cutter 5037. Under normal conditions, the cutter holder 5036 and the cutter 5037 are suspended above the tangent groove 5032.

[0050] Among them, a contact 5038 is fixedly connected to one side of the inner top of the fixing bracket 2 5033, a contact 2 5039 is provided below the contact 1 5038, and the contact 2 5039 is located at the top of the fixing sleeve 2 5074.

[0051] When the molybdenum wire breaks, the second fixing sleeve 5074 is triggered to move upward, the second contact 5039 connects upward with the first contact 5038, the hydraulic cylinder 5034 is activated, and the telescopic rod 5035 is driven downward, so that the cutter 5037 cuts the molybdenum wire downward. The time of triggering the second fixing sleeve 5074 is slightly later than the time of triggering the second pressing rod 5087.

[0052] Reference Figure 12The reel 502 includes a round rod 5021 fixedly connected to the inner wall of the fixed frame 501. A movable sleeve 5025 is movably connected to the side of the round rod 5021. A movable wheel 5022 is fixedly connected to the periphery of the movable sleeve 5025. The side of the movable wheel 5022 has a wire-passing groove 5023 and a wire-pressing groove 5024. The wire-passing groove 5023 is opened along the outer diameter of the movable wheel 5022, and the direction of the wire-pressing groove 5024 is perpendicular to the wire-passing groove 5023. A spring 5026 is fixedly connected to the periphery of the movable sleeve 5025. A pressure rod 5027 is fixedly connected to the top of the device. A pressure block 5028 is provided at the bottom center of the pressure rod 5027. The pressure rod 5027 and the pressure block 5028 fit the shape of the pressure groove 5024. One end of the pressure rod 5027 is enlarged and has a slot that can engage with the clamping rod 5076. The other end of the pressure rod 5027 is movably connected to a fixed support rod 5029. The bottom end of the fixed support rod 5029 is fixedly connected to the periphery of the movable sleeve 5025. The fixed support rod 5029 and the spring 5026 are provided on both sides of the movable wheel 5022.

[0053] In the same thread reel 504, the pressure rod 5027 normally forms a 40° angle with the horizontal plane where the movable sleeve 5025 is located, and the end slot is engaged with the clamping rod 5076. After the molybdenum wire breaks, the clamping rod 5076 moves upward and separates from the pressure rod 5027. Under the action of the contraction force of the spring 5026, the pressure rod 5027 quickly moves downward and engages with the pressure groove 5024, pressing the molybdenum wire tightly.

[0054] Working principle of the invention:

[0055] The working principle of the elastic wheel 505 and the lever assembly 507 after the molybdenum wire breaks: After the molybdenum wire breaks, the wire guide wheel 5054 loses its upward force and moves downward under the weight of its own weight and the contraction force of the spring three 5057. This causes the rack one 5059 to move downward, making the gear 5062 rotate clockwise and then drive the rack two 5071 to move upward. With the assistance of the restoring force of the spring four 5078, the upward movement of the rack two 5071 can drive the branch rod 5073, the fixed sleeve two 5074, the connecting rod 5075 and the locking rod 5076 to move upward.

[0056] The working principle of the clamping action of the molybdenum wire breakage and recycling mechanism 5: The clamping rod 5076 moves upward and separates from the second clamping rod 5087 and the first clamping rod 5027. Under the action of the contraction force of the second spring 5044 and the first spring 5026, it moves downward and engages with the second clamping groove 5046 and the first clamping groove 5024 respectively. The molybdenum wire is clamped and fixed from both sides of the cutting assembly 503. The side of the second wire wheel 504 contains the waste molybdenum wire that broke on the workpiece cutting area side, while the side of the first wire wheel 502 contains the molybdenum wire that can be reused.

[0057] The working principle of the cutting and recycling mechanism 5 after the molybdenum wire breaks: the fixed sleeve 2 5074 moves upward, so that the contact point 2 5039 at its top contacts the contact point 1 5038, which in turn triggers the hydraulic cylinder 5034 to push the telescopic rod 5035 downward. The telescopic rod 5035 drives the knife holder 5036 at its bottom to press the molybdenum wire between the cutter 5037 and the cutting groove 5032, and cuts it.

[0058] The working principle of the molybdenum wire breakage and recycling mechanism 5: After the molybdenum wire is cut by the cutting component 503, the pressure rod 5087 engages with the pressure groove 5046, fixing one end of the broken waste molybdenum wire on one side of the workpiece cutting area. At this time, the power motor 5041 rotates through the drive motor shaft, driving the movable wheel 5042 to rotate, thereby winding up the waste molybdenum wire (e.g., ...). Figure 10 After winding, manually press down the cutting plate 5084 and use the cutting blade 5085 to cut the molybdenum wire between the cutting plate 5084 and the pressure bar 5087, and then remove the waste molybdenum wire for recycling.
