Description

Technical Field

[0001] This utility model relates to an irregularly shaped electrode, specifically, to an irregularly shaped electrode and its processing apparatus. Background Technology

[0002] In the electrical discharge machining (EDM) process, to facilitate the operator's dial indicator setup, a large square reference platform is needed, while the actual area in contact with the workpiece for discharge is very small. Its structure is as follows: Figure 1 As shown, the actual structure used is electrode head 11, while the square reference platform A1 is only used for dial indicator alignment. Currently, when processing the electrode, a copper block with dimensions of 40*30*20 mm needs to be processed into... Figure 1 The structure of the copper block has a mass of 0.21KG. When processing the copper block, most of the copper material needs to be removed, which leads to a large waste of copper material. At the same time, the removal of more copper material will also increase the processing time of the machining center, thus increasing the cost. Therefore, a new electrode is needed to ensure the normal discharge of the electrode and to reduce the size of the copper blank and save processing time of the machining center without affecting the alignment of the EDM operator. Summary of the Invention

[0003] The purpose of this invention is to provide an irregularly shaped electrode and its processing apparatus to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, one of the objectives of this utility model is to provide an irregularly shaped electrode, including an electrode head, wherein an irregularly shaped reference base is fixed at the bottom of the electrode head, and the irregularly shaped reference base is a surface that is parallel to the outer arc surface and the inner arc surface of the electrode head.

[0005] The second objective of this utility model is to provide a processing device for processing irregularly shaped electrodes as described above, comprising a first receiving plate, a baffle fixed to the upper side of one end of the first receiving plate, a cylinder fixedly installed on the upper side of the end of the first receiving plate away from the baffle, a movable push plate fixed to one end of the piston rod of the cylinder, the movable push plate being disposed between the cylinder and the baffle, and the baffle and the movable push plate contacting the side walls of the irregularly shaped reference seat near the outer and inner side walls of the electrode head.

[0006] As a further improvement to this technical solution, a flipping groove is provided on the first receiving plate, and a second receiving plate is hinged inside the flipping groove. The second receiving plate is hinged inside the flipping groove, and the end of the second receiving plate near the cylinder is located on the lower side of the moving push plate.

[0007] As a further improvement to this technical solution, the second receiving plate is fixed with an upwardly inclined flat pressure plate at one end located below the movable push plate. The weight of the second receiving plate and the flat pressure plate located on the hinge point side of the second receiving plate is less than the weight of the end of the second receiving plate near the baffle.

[0008] As a further improvement to this technical solution, an arc-shaped pressing surface is provided at the connection position of the flat pressure inclined plate and the second receiving plate. An arc-shaped block is fixed at the middle position of the side of the movable push plate near the cylinder. When the second receiving plate is set horizontally, the arc-shaped block and the arc-shaped pressing surface are in contact. When the end of the second receiving plate near the baffle is set upward, the bottom of the movable push plate is in contact with the upper side wall of the flat pressure inclined plate.

[0009] As a further improvement to this technical solution, an end guard plate is screwed to the side of the baffle away from the moving push plate. Connecting strips are fixed to both ends of the end guard plate near the cylinder. Side guard plates are provided on both sides of the first receiving plate between the baffle and the cylinder. The side guard plates are fixed to the first receiving plate by connecting plates. The sides of the connecting strips and the side guard plates near the first receiving plate are on the same plane. The distance between the two connecting strips and the two side guard plates is the same as the length of the copper block of the production electrode head.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. In this irregular electrode and its processing device, the irregular electrode is designed to ensure the function of electrode head alignment and positioning. By changing the shape of the original square reference platform to the shape of the irregular reference seat in this solution, the volume of copper block used for processing the irregular electrode is reduced. This reduces copper material loss during the processing of the irregular electrode using copper block. At the same time, reducing copper material loss also shortens the processing time of the machining center, thereby improving the efficiency of irregular electrode processing.

[0012] 2. In this irregularly shaped electrode and its processing device, the copper material is processed by the processing device. During the processing, the connecting strip and the side guard plate can position the copper material. Moreover, during the processing of the processing device, the connecting strip and the side guard plate will not affect the processing of the edge of the irregularly shaped electrode, ensuring the normal processing of the irregularly shaped electrode.

[0023] 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.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Example

[0025] Please see Figure 1As shown, current electrodes, in order to facilitate operator calibration, have a very large square reference platform A1, while the actual area of ​​the electrode head 11 used for discharge is very small. This results in the removal of a large amount of copper material during electrode processing, which cannot be further processed, leading to a waste of copper. Currently, in the processing... Figure 1 The electrode shown is made of copper material with dimensions of 40*30*20 (mm) and a weight of 0.21kg. It takes 36 minutes to process one electrode in a machining center, which is time-consuming and removes a lot of copper material.

[0026] This solution provides an irregularly shaped electrode, which can reduce copper consumption and speed up electrode processing. It includes an electrode head 11, which is the same as the electrode head 11 in current electrodes. The electrode head 11 is arc-shaped, and an irregularly shaped reference seat 1 is fixed at the bottom of the electrode head 11. The irregularly shaped reference seat 1 is a parallel surface to the outer and inner arc surfaces of the electrode head 11. (Refer to...) Figure 3 The electrode in this design is located on the left, while the electrode in the existing design is located on the right. Compared with the existing electrode, the electrode in this design lacks two corners corresponding to the inner and outer arc surfaces of the electrode head 11. At the same time, the irregular reference seat 1 is parallel to the outer and inner arc surfaces. Therefore, when machining the electrode in this design, the distance between the two parallel sides can be used as the width of the copper material for machining the electrode. The copper material size for machining the electrode in this design is 45*20*20 (mm), and the mass is 0.16 kg.

[0027] In this solution, the weight of copper material used for processing electrodes is reduced by 0.05 kg compared to the original. Based on the current price of copper material of 85 yuan per kilogram, processing one electrode can save 4.25 yuan. At the same time, the electrode processing in this solution takes 25 minutes when using a machining center, thus reducing the processing time.

[0028] The electrodes in this solution can speed up production, reduce the amount of copper used, and also reduce the amount of copper removed. Furthermore, the electrodes in this solution still have the same side for aligning with the existing electrodes, allowing operators to still use the aligner for proper alignment.

[0029] The second objective of this utility model is to provide a processing apparatus for processing irregularly shaped electrodes as described above, with reference to... Figures 4-8The device includes a first receiving plate 2, with a baffle fixed to the upper side of one end of the first receiving plate 2. A cylinder 5 is fixedly installed on the upper side of the first receiving plate 2 away from the baffle. A movable push plate 6 is fixed to one end of the piston rod of the cylinder 5. The movable push plate 6 is disposed between the cylinder 5 and the baffle. The movable push plate 6 is slidably disposed on the upper side of the first receiving plate 2. The baffle and the movable push plate 6 are arranged in parallel. When the device clamps the electrode, the baffle and the movable push plate 6 contact the side walls of the irregular reference seat 1 that are close to the outer and inner side walls of the electrode head 11. At the same time, the height of the baffle and the movable push plate 6 is the same as the thickness of the irregular reference seat 1. This is to ensure that the upper side of the irregular reference seat 1 can be machined by the drill bit.

[0030] At the same time, when the baffle and the movable push plate 6 contact the side wall of the irregular reference seat 1, the two ends of the baffle and the movable push plate 6 are not aligned with the two ends of the side wall of the irregular reference seat 1. The length of the baffle and the movable push plate 6 is shorter than the length of the contacting side. This is so that when the drill bit is machining the side wall of the irregular reference seat 1 near the end of the electrode head 11, the drill bit will not touch the baffle and the movable push plate 6.

[0031] Furthermore, because the irregular-shaped reference base 1 is irregularly shaped, meaning it is not a symmetrical structure, refer to... Figure 5 As shown, to ensure precise placement of the copper material on the device, an end guard plate 31 is screwed onto the side of the baffle away from the moving push plate 6. Connecting strips 3 are fixed to both ends of the end guard plate 31 near the cylinder 5. Side guard plates 4 are provided on both sides of the first receiving plate 2 between the baffle and the cylinder 5. The side guard plates 4 are fixed to the first receiving plate 2 via connecting plates. The connecting strips 3 and the side guard plates 4 are at the same height, and the distance between the connecting strips 3 and the side guard plates 4 on the same side of the first receiving plate 2 is less than the distance between the copper material. The width of the copper material is such that its side closest to the first receiving plate 2 is on the same plane. The distance between the two connecting strips 3 and the two side guard plates 4 is the same as the length of the copper block of the production electrode head 11. When the copper material is placed on the first receiving plate 2, the first receiving plate 2 receives the copper material. The connecting strips 3 and the side guard plates 4 restrict the sidewalls of the copper material, preventing the copper material from moving left and right on the first receiving plate 2. At the same time, the connecting strips 3 and the side guard plates 4 are positioned near the four corners of the copper material, that is, the connecting strips 3 and the side guard plates 4 are located as shown in the figure. Figure 3 The dotted lines on the left and right sides of the left electrode indicate the positions needed later when the drill bit is cutting the copper material. Figure 3 The copper material in the dotted line section of the left figure is cut off. If the connecting strip 3 or the side guard plate 4 is too close to the middle of the side of the copper material, or too close to the non-cutting position on the irregular reference seat 1, it will affect the drill bit's ability to cut the copper material.

[0032] After the drill bit finishes cutting the copper material, the copper material is not in contact with the connecting strip 3 and the side guard plate 4, and its state is as follows. Figure 4As shown, after the cylinder 5 drives the movable push plate 6 away from the irregular reference seat 1, the worker can remove the electrode. Then, the worker places new copper material on the device. Because the height of the movable push plate 6 and the baffle is relatively small, the worker may place the copper material on the baffle, which will affect the fixation of the copper material. To facilitate the worker's placement of the copper material, a flipping groove 21 is provided on the first receiving plate 2. A second receiving plate 7 is hinged inside the flipping groove 21. The second receiving plate 7 is hinged inside the flipping groove 21 and is close to... One end of the cylinder 5 is located on the lower side of the movable push plate 6. The second receiving plate 7 and the flipping groove 21 are hinged at the end of the second receiving plate 7 near the cylinder 5, but are not fixed to the end of the second receiving plate 7. The end of the second receiving plate 7 near the cylinder 5 is a certain distance away from the hinge position of the second receiving plate 7 and the flipping groove 21. At the same time, an upwardly inclined flat pressure plate 71 is fixed at the end of the second receiving plate 7 located on the lower side of the movable push plate 6. The weight of the second receiving plate 7 and the flat pressure plate 71 located on the hinge point side of the second receiving plate 7 is... The weight is less than that of the end of the second receiving plate 7 near the baffle. In its natural state, the end of the second receiving plate 7 near the baffle moves downwards, while the flat pressure plate 71 moves up and down. Simultaneously, an arc-shaped pressing surface is provided at the connection between the flat pressure plate 71 and the second receiving plate 7. An arc-shaped block 61 is fixed at the center of the side of the moving push plate 6 near the cylinder 5. When the second receiving plate 7 is horizontally positioned, the moving push plate 6 clamps the copper material, and the arc-shaped block 61 contacts the arc-shaped pressing surface. The arc-shaped block 61 blocks the arc-shaped pressing surface. At this time, the second receiving plate... 7. The end near the baffle will not move downward. When the moving push plate 6 releases the copper material, the moving push plate 6 will press the flat pressure inclined plate 71, causing the end of the flat pressure inclined plate 71 near the baffle to move upward. When the end of the second receiving plate 7 near the baffle is tilted upward, the bottom of the moving push plate 6 contacts the upper side wall of the flat pressure inclined plate 71. That is, the moving push plate 6 or the arc block 61 will contact the flat pressure inclined plate 71. Through the restriction of the moving push plate 6 and the arc block 61, the end of the second receiving plate 7 near the baffle is in an upward tilted or horizontal state.

[0033] When the second receiving plate 7 is tilted upwards near the baffle, the worker places the copper material on the second receiving plate 7. At this time, the side of the copper material contacts the side wall of the connecting strip 3 and the side guard plate 4. The connecting strip 3 and the side guard plate 4 restrict the copper material, allowing it to be supported by the temperature of the second receiving plate 7. Guided by the second receiving plate 7, the copper material is positioned according to the tilt angle of the second receiving plate 7. When the cylinder 5 pushes the moving push plate 6 closer to the baffle, the moving push plate 6 gradually approaches the copper material. During the process, the moving push plate 6 gradually separates from the flat pressure plate 71. After the moving push plate 6 separates from the flat pressure plate 71, the end of the second receiving plate 7 near the baffle rotates downward under the influence of gravity. The copper material follows the second receiving plate 7 and gradually approaches the first receiving plate 2. When the second receiving plate 7 is set horizontally, the copper material contacts the first receiving plate 2. Then the moving push plate 6 pushes the copper material to contact the baffle. At this time, the copper material is fixed. Then the drill bit processes the copper material, so that the copper material is cut into the state of the electrode in the cost scheme.

[0034] The copper material is processed by the processing device. During the processing, the connecting strip 3 and the side guard plate 4 can position the copper material. Furthermore, during the processing, the connecting strip 3 and the side guard plate 4 will not affect the edge processing of the irregular electrode in this solution, ensuring the normal processing of the irregular electrode.

[0035] In this solution, the cutting of copper material by the drill bit and the trajectory of the cutting copper material by the drill bit are existing technologies, and will not be described in detail here.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
