Description

Technical Field

[0001] This utility model relates to the field of wire EDM technology, and in particular to a clamping assembly, a feeding mechanism, and a wire EDM device. Background Technology

[0002] In the field of wire cutting technology, especially when cutting photovoltaic silicon, sapphire, semiconductors, silicon carbide, and magnetic materials, it is necessary to fix the workpiece before cutting. For example, existing wire cutting devices for magnetic materials use a method where the workpiece is directly glued to a single-layer marble slab, and then the marble slab is glued to an iron plate for cutting. After cutting, a special method (such as high-temperature debonding) is required to separate the iron plate from the marble slab so that the iron plate can be reused. The disadvantages of this method are that the workpiece needs to be glued to both the marble slab and the iron plate before cutting, making the pre-cutting preparation process cumbersome; at the same time, the marble slab needs to be separated from the iron plate after cutting, resulting in many steps involved in the cutting process, making operation inconvenient and leading to low cutting efficiency. In addition, since the iron plate is reused, it will inevitably undergo some deformation, which will affect the cutting quality. Utility Model Content

[0046] Compared with the prior art, the advantages of this utility model are:

[0047] (1) The workpiece base plate assembly of this utility model can be connected together by fixing elements, which is beneficial to improving the operation convenience, connection accuracy and stability of the base plate. When the workpiece base plate assembly of this utility model is applied to the wire cutting field, the connecting plate is used to bond with the workpiece to be processed, and the base plate is provided with fixing elements. The connecting plate and the base plate are connected by fixing elements, without the need to bond the connecting plate to the base plate. The connecting plate, the base plate and the workpiece to be processed can be easily integrated into a whole and fed as a whole outside the wire cutting device, which is beneficial to improving the cutting efficiency and cutting quality of the wire cutting machine. In addition, after the cutting is completed, it is only necessary to release the locking relationship between the base plate and the connecting plate to separate the base plate and the connecting plate.

[0048] (2) The clamping assembly of this utility model clamps the workpiece base plate assembly by using the installation body, which is configured as a clamping slide rail or a clamping slider, to clamp the workpiece base plate assembly. Automatic feeding can be achieved by the sliding of the workpiece base plate assembly on it. After the workpiece is in place, the workpiece base plate assembly can be clamped, thereby improving the clamping stability of the workpiece base plate assembly and thus improving the cutting quality.

[0077] The present invention will be further described below with reference to the accompanying drawings.

[0078] According to a first aspect of the present invention, the present invention provides a workpiece base plate assembly 100 for connection with a workpiece 400 to be processed, so that the workpiece 400 to be processed can be loaded as a whole.

[0079] Specifically, such as Figure 1A , Figure 1B and Figure 2 As shown, the workpiece base plate assembly 100 includes a connecting plate 110 and a base plate 120. One side (e.g., the bottom side) of the connecting plate 110 is used to connect with the workpiece 400 to be processed, and the opposite side of the connecting plate 110 is fitted to the base plate 120. A fixing element 130 is provided on the base plate 120, which can engage with the connecting plate 110 to fix the connecting plate 110 and the base plate 120 together. Therefore, the workpiece base plate assembly 100 of this utility model can connect the connecting plate 110 and the base plate 120 together by means of the fixing element 130, which is beneficial to improving the operational convenience, connection accuracy and stability of the base plate 120. When the workpiece base plate assembly 100 of this utility model is applied to the wire cutting field, the connecting plate 110 is used to bond with the workpiece to be processed, and the fixing element 130 is provided on the base plate 120 to connect the connecting plate 110 and the base plate 120 by means of the fixing element 130, without the need to bond the connecting plate 110 and the base plate 120. Before the wire cutting device is loaded, the connecting plate 110, the base plate 120 and the workpiece 400 to be processed can be conveniently shaped. By forming a single unit, the wire EDM machine can achieve overall material loading, which improves its cutting efficiency and quality. Furthermore, after cutting, the base plate 120 and connecting plate 110 can be separated simply by disengaging the interlocking connection, eliminating the need for high-temperature degumming processes. This saves labor time and increases cutting efficiency. Simultaneously, omitting the high-temperature degumming process reduces the deformation rate of the base plate 120, increases its reusability and extends its service life, improves the fixing accuracy of the workpiece 400, and ultimately enhances both cutting quality and efficiency.

[0080] Furthermore, since the connecting plate 110 and the base plate 120 are interlocked, there is no need to use adhesive to bond the connecting plate 110 and the base plate 120, which makes it easier and faster to fix the workpiece 400 to be processed. Moreover, using the fixing element 130 for interlocking connection helps to further improve the alignment accuracy between the connecting plate 110 and the base plate 120.

[0081] Further, see Figure 2The connecting plate 110 has a recess 111, into which the fixing element 130 can be inserted and engaged. The recess 111 is constructed as a groove recessed into the connecting plate 110, and the inner wall of the groove is constructed as one or more of a plane, an inclined plane, and a curved surface. For example, the inner wall of the groove can be constructed as an inclined plane sloping inwards towards the connecting plate 110, thus giving the groove a V-shaped cross-section; or the inner wall of the groove can be constructed as a plane extending towards the connecting plate 110, thus giving the groove a U-shaped groove. Alternatively, the groove can also have other structural forms such as an arc-shaped groove to provide a space for engaging with the fixing element 130. The two inner walls of the aforementioned V-shaped, U-shaped, or arc-shaped groove can be symmetrically arranged.

[0082] In addition, the recess 111 can also be a dovetail groove structure.

[0083] Furthermore, the two inner walls of the groove can also be configured as asymmetrical structures, for example, one inner wall is constructed as an inclined surface that slopes toward the interior of the connecting plate 110, while the other inner wall is constructed as a planar structure that extends toward the connecting plate 110, etc.

[0084] Accordingly, the fixing element 130 is configured as a fixing block, one end of which is secured by a fastener 131 (e.g., Figure 3 As shown, the fixing element 130 is connected to the base plate 120. The other end of the fixing element 130 is configured to fit into the groove, allowing the other end of the fixing element 130 to be inserted into the groove and fit into it. Under the action of the fastener 131, it abuts against the inner wall of the groove. For example, if the groove has a V-shaped cross-section, the other end of the fixing block is configured to have an inclined outer wall (i.e., a V-shaped tip). The inclination angle of the fixing block can be the same as the inclination angle of the inner wall of the groove. Thus, when the end of the fixing block is inserted into the groove, its inclined outer wall can fit against the inner wall of the groove, thereby locking and fixing the two together.

[0085] To provide a better locking effect, when the groove is constructed in the form of a V-shaped cross section, the included angle between its two inclined sidewalls is 30°-120°. Correspondingly, the V-shaped tip of the fixing block also has an included angle of less than 120°, or the included angle of the V-shaped tip of the fixing block is slightly larger than the included angle between the two inclined sidewalls of the groove.

[0086] Recesses 111 are respectively provided on two opposite sides of the connecting plate 110 in the width direction (e.g., the left and right sides of the connecting plate 110), and the recesses 111 are provided continuously in the length direction of the connecting plate 110, so that they can be engaged and fixed throughout the entire length of the connecting plate 110. Alternatively, multiple recesses 111 can be provided on both sides of the connecting plate 110, and the multiple recesses 111 on the same side of the connecting plate 110 are spaced apart in the length direction of the connecting plate 110.

[0087] Optionally, the fixing elements 130 are respectively provided on two opposite sides of the base plate 120, and each side of the base plate 120 is provided with a fixing element 130. For example, the fixing element 130 can be set to be approximately the same length as the base plate 120.

[0088] Optionally, the fixing elements 130 are respectively disposed on two opposite sides of the base plate 120. Each side of the base plate 120 is provided with at least two fixing elements 130. All fixing elements 130 are arranged sequentially along the length direction of the base plate. Preferably, all adjacent fixing elements 130 are equally spaced. Therefore, during fixing, the fixing elements 130 on one side of the base plate 120 can be fixed to the base plate 120 and inserted into the recess 111 for engagement. After fine-tuning the base plate 120 and the connecting plate 110 to align them, the fixing elements 130 on the other side can be inserted into the recess 111 on the other side and fixed to the base plate 120, thereby ensuring that the connecting plate 110 and the base plate 120 are aligned and connected.

[0089] Multiple fixing elements 130 can be provided and spaced apart along the length of the base plate 120. For example, five fixing elements 130 can be provided, and the fixing elements 130 on the left and right sides of the base plate 120 can be arranged symmetrically to each other.

[0090] Optionally, such as Figure 1B As shown, the connecting plate 110 is a one-piece plate structure (i.e., a single-plate structure), so the recess 111 can be a groove opened along its length on the left and right sides of the connecting plate 110. The recess 111 can be a dovetail groove.

[0091] Optionally, please combine Figure 1A and Figure 2 The connecting plate 110 includes a first plate 112 and a second plate 113 disposed opposite to each other. The sides of the first plate 112 and the second plate 113 are respectively provided with one or more structures selected from planes, inclined surfaces, and curved surfaces extending inward to form grooves. For example, the first plate 112 and the second plate 113 are symmetrically arranged about their contact surfaces, and both sides are provided with chamfers. Thus, after the first plate 112 and the second plate 113 are connected to each other, the two chamfers facing each other form the V-shaped groove described above.

[0092] Preferably, the workpiece 400 to be processed is made of a hard and brittle material such as magnetic material, and the connecting plate 110 is a marble slab. When the connecting plate 110 adopts a split structure, the first plate 112 and the second plate 113 can be fixed by means of bonding or other methods, or the first plate 112 and the second plate 113 can also be integrally formed.

[0093] In addition, the connecting plate 110 can also be a resin board or an asbestos board. Alternatively, it can be a plate-like structure formed from other easily cut materials.

[0094] Furthermore, the base plate 120 can be an iron plate or a plate-like structure made of other metal materials.

[0095] The connecting plate 110 has an adhesive layer on the side that connects to the workpiece 400 to be processed, and the connecting plate 110 is fixedly connected to the workpiece 400 through the adhesive layer. For example, when the connecting plate 110 adopts a split structure, the first plate 112 is the plate closer to the workpiece, so the bottom of the first plate 112 can be fixed to the workpiece 400 to be processed by adhesive bonding.

[0096] like Figure 4 As shown, the base plate 120 is also provided with at least two connecting slots 121, each of which is slidably connected to the mounting body, thereby enabling material feeding.

[0097] A buffer mechanism is provided at the rear end of the base plate 120 or the connecting plate 110. The buffer mechanism can be, for example, a buffer pad. When the workpiece base plate assembly 100 is loaded, the buffer mechanism at its rear end can buffer the impact force pushing the workpiece base plate assembly 100 during loading, thereby preventing the workpiece base plate assembly 100 from directly colliding with the wire cutting device (for example, buffering can be provided between the workpiece base plate assembly 100 and the upper frame of the wire cutting device). Preferably, the buffer mechanism is made of polyurethane material.

[0098] like Figure 3 As shown, a handle 155 is also provided at the front end of the base plate 120. The handle 155 is used to apply force to the base plate 120. By pushing or pulling the handle 155, the workpiece base plate assembly 100 can be pushed as a whole for loading or unloading.

[0099] According to a second aspect of the present invention, the present invention also provides a clamping assembly 200, which includes the workpiece base plate assembly 100 described above, and also includes a clamping device. After the workpiece base plate assembly 100 is loaded (fed), the clamping device clamps the workpiece base plate assembly 100, thereby enabling automatic feeding and clamping of the workpiece 400 to be processed.

[0100] like Figure 1A , Figure 3 and Figure 4As shown, the clamping assembly 200 also includes a clamping and fixing mechanism, which may be, for example, a sliding fixing mechanism. Specifically, the clamping and fixing mechanism includes a clamping slide rail or a clamping slider, through which the workpiece base plate assembly 100 is loaded. The clamping slide rail is used to cooperate with the pre-clamping guide slider 210 or clamping head 220 described below to achieve loading. The mounting body described above can be a structure of the clamping and fixing mechanism.

[0101] Specifically, please combine Figure 1A , Figure 3 and Figure 4 The clamping slide rail is provided with a slide groove 153 (e.g. Figure 1A As shown), in a preferred embodiment, the slide 153 extends along the length direction of the base plate 120 (when clamped vertically); it is understood that the slide 153 may also have other construction methods, such as extending along the width direction when clamped horizontally (the slide 153 can be formed by rotating 90 degrees on the basis of the above preferred embodiment to form a slide 153 extending along the width direction of the base plate 120).

[0102] For example, in an embodiment where the slide groove 153 extends along the length of the base plate 120, a sliding clamping inclined surface 154 is provided on the inner wall of the slide groove 153 (e.g., Figure 4 (As shown). The clamping slide rail may include a first slide rail 151 disposed opposite to it (e.g. Figure 3 and Figure 4 (as shown) and the second slide rail 152 (as shown) Figure 4 As shown), the sliding clamping inclined surface 154 includes a first sliding clamping inclined surface 1541 respectively disposed on the first slide rail 151 (e.g. Figure 4 and Figure 6 (as shown) and the second sliding clamping inclined surface 1542 (as shown) provided on the second slide rail 152 Figure 4 (As shown). The first sliding clamping inclined surface 1541 and the second sliding clamping inclined surface 1542 are inclined downward and away from each other, so that a groove 153 is formed between the first slide rail 151 and the second slide rail 152. The groove 153 can respectively interact with the pre-installed clamping guide slider 210 or the clamping head 220 (e.g., Figure 6 (as shown) to complement each other.

[0103] In addition, such as Figure 4 As shown, the base plate 120 is also provided with at least two connecting grooves 121. The bottom of the first slide rail 151 is provided with a first connecting boss 1511, and the bottom of the second slide rail 152 is provided with a second connecting boss 1521. The first connecting boss 1511 and the second connecting boss 1521 are respectively slidably disposed in the corresponding connecting grooves 121.

[0104] Understandably, the base plate 120 can also be fixedly connected to the first slide rail 151 or the second slide rail 152 in other ways.

[0105] like Figure 3 As shown, a handle 155 is also provided at the front end of the base plate 120. The handle 155 is used to apply force to the base plate 120. By pushing or pulling the handle 155, the workpiece base plate assembly 100 can be pushed as a whole for loading or unloading.

[0106] Specifically, such as Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the clamping device includes a clamping plate 260 and a pre-clamping guide slider 210 disposed on the clamping plate 260. The pre-clamping guide slider 210 is slidably connected to the groove 153 of the clamping slide rail of the workpiece base plate assembly 100.

[0107] Among them, such as Figure 4 As shown, guide slopes 211 are provided on both sides of the pre-clamping guide slider 210, and the guide slopes 211 are adapted to the sliding clamping slopes 154 of the slide groove 153.

[0108] In one embodiment, during clamping, the workpiece base plate assembly 100 can be pushed along its length, thereby allowing the pre-clamping guide slider 210 to be inserted into the groove 153 between the first slide rail 151 and the second slide rail 152. The guide ramps 211 on both sides of the pre-clamping guide slider 210 then engage with the first sliding clamping ramp 1541 on the first slide rail 151 and the second sliding clamping ramp 1542 on the second slide rail 152, respectively (e.g., ...). Figure 4 (As shown), this allows the workpiece base plate assembly 100 to be fed smoothly.

[0109] Understandably, when the clamping and fixing mechanism 150 is constructed as a clamping slider, a corresponding groove will be provided on the pre-clamping guide slider 210, so that the clamping slider can be inserted into the groove of the pre-clamping guide slider 210 to achieve sliding feeding.

[0110] The number of pre-clamping guide sliders 210 is at least two, and the at least two pre-clamping guide sliders 210 are arranged at equal intervals. That is to say, the pre-clamping guide sliders 210 do not extend along the entire length of the slide groove 153, but are arranged at intervals, thereby reducing the friction between the pre-clamping guide sliders 210 and the slide groove 153, making it easier to push the workpiece base plate assembly 100 for loading.

[0111] The clamp also includes a clamping head 220 disposed on the clamping plate 260, such as Figure 5As shown, the clamping heads 220 and pre-clamping guide sliders 210 are alternately arranged. For example, there are 3 pre-clamping guide sliders 210 and 2 clamping heads 220, which are arranged such that one clamping head 220 is placed between two pre-clamping guide sliders 210.

[0112] The clamping head 220 is configured to clamp the clamping slide rail when it moves to the clamping position, so that the workpiece base plate assembly 100 separates from the pre-clamping guide slider 210 and comes into contact with the clamping plate 260; the clamping head 220 is also configured to release the clamping slide rail when it moves to the releasing position, so that the workpiece base plate assembly 100 comes into contact with the pre-clamping guide slider 210 and comes into contact with the clamping plate 260.

[0113] Specifically, the clamping head 220 is provided with fixed inclined surfaces 221 on both sides (e.g., Figure 6 As shown, the fixed inclined surface 221 is adapted to the sliding clamping inclined surface 154. When the clamping head 220 (upward) moves to the clamping position, the fixed inclined surface 221 of the clamping head 220 approaches and abuts against the sliding clamping inclined surface 154 of the slide groove 153, thereby fixing the clamping slide rail to the clamping plate 260; when the clamping head 220 (downward) moves to the releasing position, the fixed inclined surface 221 of the clamping head 220 moves away from and separates from the sliding clamping inclined surface 154 of the slide groove 153, thereby separating the clamping slide rail from the clamping plate 260.

[0114] The fixing inclined surface 221 of the clamping head 220 is set in a similar manner to the guide inclined surface 211 on the pre-clamping guide slider 210 (e.g., Figure 4 and Figure 6 (As shown). However, unlike the pre-clamping guide slider 210, when the clamping head 220 is in its released position, its fixed inclined surface 221 is lower than the guide inclined surface 211 on the pre-clamping guide slider 210. That is, the fixed inclined surfaces 221 on both sides of the clamping head 220 cannot contact the corresponding first sliding clamping inclined surface 1541 and second sliding clamping inclined surface 1542. At this time, the guide inclined surface 211 on the pre-clamping guide slider 210 is higher than the fixed inclined surface 221 on the clamping head 220, so the guide inclined surfaces 211 on both sides of the pre-clamping guide slider 210 can just contact the corresponding first sliding clamping inclined surface 1541 and second sliding clamping inclined surface 1542. In other words, at this time, the pre-clamping guide slider 210 can play the main supporting and connecting role.

[0115] Conversely, when the clamping head 220 moves from its released position to its clamping position, its fixed inclined surface 221 moves upward and comes into contact with the first sliding clamping inclined surface 1541 on the corresponding first slide rail 151 and the second sliding clamping inclined surface 1542 on the corresponding second slide rail 152, thereby clamping the first slide rail 151 and the second slide rail 152. Due to the movement of the clamping head 220, the first slide rail 151 and the second slide rail 152 move together, causing the first slide rail 151 and the second slide rail 152 to separate from the pre-clamping guide slider 210. That is, the guide inclined surfaces 211 on both sides of the pre-clamping guide slider 210 separate from the corresponding first sliding clamping inclined surfaces 1541 and second sliding clamping inclined surfaces 1542. In other words, at this time, the clamping head 220 plays a major supporting and connecting role.

[0116] The clamp also includes an actuation unit 230, such as Figure 5 As shown, the execution unit 230 is connected to the clamping head 220 to drive the clamping head 220 to move in the height direction of the slide 153.

[0117] When the clamping head 220 moves to the clamping position, the execution unit 230 drives the clamping head 220 and moves the workpiece base plate assembly 100 closer to the clamping plate 260, so that the clamping plate 260 and the clamping slide rail of the workpiece base plate assembly 100 contact and clamp; when the clamping head 220 moves to the releasing position, the execution unit 230 drives the clamping head 220 and moves the workpiece base plate assembly 100 away from the clamping plate 260, so that the clamping plate 260 and the clamping slide rail of the workpiece base plate assembly 100 separate.

[0118] As mentioned above, during loading, the workpiece base plate assembly 100 can be loaded as a whole by using the handle 155, so that the groove 153 of the clamping slide rail of the workpiece base plate assembly 100 is aligned with the pre-clamping guide slider 210, and the workpiece base plate assembly 100 is pushed along the length direction of the base plate 120 to load the workpiece.

[0119] When the pre-clamping guide slider 210 is inserted into the groove 153 of the clamping slide rail of the workpiece base plate assembly 100, the guide slopes 211 on both sides of the pre-clamping guide slider 210 can just contact the corresponding first sliding clamping slope 1541 and second sliding clamping slope 1542 to play a guiding role; while at this time, when the clamping head 220 is in its released position, the fixed slope 221 on it does not contact the corresponding first sliding clamping slope 1541 and second sliding clamping slope 1542.

[0120] When the clamping head 220 is driven upward by the execution unit 230, it moves from its released position to its clamping position. The upward movement of its fixed inclined surface 221 brings it into contact with the first sliding clamping inclined surface 1541 on the corresponding first slide rail 151 and the second sliding clamping inclined surface 1542 on the corresponding second slide rail 152. This causes the first and second slide rails 151 and 152 to move together, thus separating them from the pre-clamping guide slider 210. Specifically, the guide inclined surfaces 211 on both sides of the pre-clamping guide slider 210 separate from the corresponding first and second sliding clamping inclined surfaces 1541 and 1542. The clamping head 220 moves the first and second slide rails 151 and 152 together until their upper surfaces contact the bottom surface of the clamping plate 260, at which point the automatic clamping of the workpiece base plate assembly 100 is completed.

[0121] The clamping plate 260 has contact bosses (not shown in the figure) on the surface corresponding to the clamping slide rail. The clamping plate 260 and the clamping slide rail can contact each other through the contact bosses. Alternatively, contact bosses can be provided on the upper surfaces of the first slide rail 151 and the second slide rail 152 respectively, so that when the upper surfaces of the first slide rail 151 and the second slide rail 152 contact the bottom surface of the clamping plate 260, they can contact each other through the contact bosses. The contact bosses can reduce the contact area and avoid uneven contact between the clamping plate 260 and the workpiece base plate assembly 100.

[0122] like Figure 3 As shown, the clamping device also includes a detection unit 240 disposed on the clamping plate 260. The detection unit 240 is used to detect whether the clamping plate 260 and the clamping slide rail of the workpiece base plate assembly 100 are in contact and clamped. The detection unit 240 may be, for example, a distance sensor or a proximity switch. The detection unit 240 can determine whether the two are clamped based on whether the distance between the upper surface of the first slide rail 151 and the second slide rail 152 and the bottom surface of the clamping plate 260 meets the set conditions.

[0123] In one embodiment, the actuation unit 230 includes a hydraulic cylinder located on the side of the clamping plate 260 away from the clamping head; the clamping device also includes a power unit 250 (e.g., Figure 14 As shown, the power unit 250 includes a hydraulic power unit connected to a hydraulic cylinder. Furthermore, the actuator 230 can also be another structure capable of providing power, such as an electric motor or a cylinder.

[0124] The length direction of the clamping plate 260 is the same as the length direction of the base plate 120 of the workpiece base plate assembly 100, so the length direction of the workpiece base plate assembly 100 is its feeding direction.

[0125] According to a third aspect of this utility model, such as Figures 9-13 As shown, this utility model also provides a feeding mechanism 300, including the clamping assembly 200 described above or the workpiece base plate assembly 100 described above, such as... Figures 9-10 As shown, it also includes a slide box 310 and a feed drive unit slidably connected to the slide box 310. The slide box 310 is also fixedly connected to the clamping assembly 200. The feed drive unit drives the slide box 310 and the clamping assembly 200 to move to achieve feed.

[0126] The clamping assembly 200 is located at the bottom of the slide box 310. The clamping direction of the clamping assembly 200 is consistent with the length or width direction of the base plate 120. For example, in vertical clamping (feeding and unloading along the front-to-back direction of the slicer), the clamping direction of the clamping assembly 200 is consistent with the length direction of the base plate 120, thereby reducing the overall size of the slide box 310 in the width direction. The cantilever structure formed by the slide box 310 and the feed drive unit is shorter, thereby improving the stability of the feed mechanism 300 and thus increasing the cutting progress. Alternatively, in horizontal clamping (feeding and unloading along the left-to-right direction of the slicer), the clamping direction of the clamping assembly 200 is consistent with the width direction of the base plate 120, thereby reducing the overall size of the slide box 310 in the length direction. The feed mechanism 300 also includes a moving component 330, which includes a slidably connected guide rail and a moving slider. One of the guide rail and the moving slider is located on the side of the slide box 310, and the other is located on the feed drive unit. For example, a guide rail can be provided on the side of the slide box 310, and a movable slider can be provided on the feed drive unit. The slide box 310 is driven to move on the feed mechanism 300 by the movable drive mechanism.

[0127] The feed mechanism 300 also includes a feed base 320, which is separately mounted on the upper frame 340 of the wire cutting device. The feed base 320 is connected to the upper frame 340 via a support 360 and is also fixedly connected to the feed drive unit. The support 360 improves the stability of the feed base 320 during installation. The support 360 can be, for example, a triangular bracket structure.

[0128] like Figure 9 , Figure 11 , Figure 12 and Figure 13As shown, the feed mechanism 300 also includes a sealing and chip removal mechanism 370, which includes a scraper 372 and a guard plate 311. There can be two scrapers 372, located on either side of the guard plate 311 at the lower end of the slide box 310. One side of each scraper 372 is fixed to the upper frame 340 via a sealing plate 371, and the other side of each scraper 372 contacts the side of the guard plate 311. The guard plate 311 can replace the bellows seal structure in the prior art, and a hydraulic power unit can be installed inside it. When the slide box 310 moves, the scraper 372 can scrape away cutting chips and splashed cutting fluid from the side wall of the guard plate 311. The guard plate 311 can be a stainless steel plate.

[0129] Among them, the end of the scraper 372 that contacts the side wall of the guard plate 311 is provided with a scraping part 3721, such as Figure 13 As shown, the scraping portion 3721 can be beveled or chamfered, thus forming a pointed structure to facilitate the scraping of cutting chips on the sidewall of the guard plate 311, thereby preventing the accumulation of cutting chips. Furthermore, the scraper is made of a soft material (e.g., rubber) to avoid metal-to-metal friction, thus facilitating maintenance and upkeep.

[0130] According to the fourth aspect of this utility model, such as Figure 14 As shown, this utility model also provides a wire EDM device, which includes the feed mechanism 300 and upper frame described above. The upper frame is connected to the feed base 320 of the feed mechanism 300, or the clamping assembly 200 described above, or the workpiece base plate assembly 100 described above. Furthermore, the wire EDM device may also include other components and elements, which may adopt the same structural design as in the prior art; these will not be described further in this utility model.

[0131] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
