Description

Technical Field

[0001] This utility model relates to the field of wire cutting machine tool technology, specifically a wire cutting machine tool with a protective structure. Background Technology

[0002] A wire EDM machine is a special processing equipment that uses a thin metal wire as an electrode to corrode metal materials through pulse discharge. Its core components include the machine tool body, CNC system and high-frequency power supply. It can achieve high-precision cutting of metals with complex shapes, and is especially suitable for processing high-hardness, high-toughness materials and precision parts.

[0003] The prior art (publication number CN211661274U, publication date 2020-10-13) discloses a molybdenum wire protection device for a wire EDM machine and a wire EDM machine. The device includes a wire EDM machine tool, a coolant pipe mounted on the machine tool beam, a wire fixing component installed at the bottom of the end of the beam away from the wire spool, a first water spray plate, and a wire protection assembly mounted on the first water spray plate. The wire protection assembly mounted on the water spray plate has a simple structure and is fixed by magnetic attraction, facilitating installation and removal. The assembly has gaps to facilitate the installation of the molybdenum wire and components, improving installation efficiency. The inner wall is V-shaped, which can concentrate the coolant flow, improving the lubrication, cooling, and cleaning effects of the coolant. The outer wall is V-shaped, protecting the lower water spray plate and the molybdenum wire, and preventing coolant splashing, thus protecting the working environment. Fixed to a fixing part, this product prevents the molybdenum wire from breaking and flying out of the water spray plate, thus preventing safety hazards to the operator.

[0004] While existing technologies can prevent coolant splashing and protect the working environment, the distance between the covers is fixed during use, and the degree of splashing varies depending on the size of the workpiece. The fixed-position covers have certain limitations in providing protection.

[0005] Therefore, we propose a wire cutting machine tool with a protective structure to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a wire cutting machine tool with a protective structure to solve the problem mentioned in the background art that during use, the distance between the covers is fixed, the degree of splashing varies with the size of the workpiece, and the fixed-position covers have certain limitations in protection.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a wire cutting machine tool with a protective structure, comprising a machine tool body, a placement platform provided on the upper surface of the machine tool body, protective covers for preventing splashing symmetrically arranged on the left and right sides above the machine tool body, and an adjustment mechanism provided between the rear side of the protective cover and the machine tool body, and the adjustment mechanism adjusts the position of the protective cover by moving the extrusion block contained therein.

[0008] Furthermore, a side plate is fixedly connected to the side of the placement platform, and a connecting rod is slidably connected to the side plate. A pull plate is fixedly connected to the upper end of the connecting rod, and a first spring is fixedly connected between the lower surface of the pull plate and the upper surface of the side plate.

[0009] Furthermore, the lower end of the docking rod engages with the corresponding docking groove on the machine tool body, and the docking rods are distributed at equal intervals in the transverse direction about the side plate. The pull plate forms a sliding structure with the side plate through the first spring.

[0010] Furthermore, the adjustment mechanism includes a threaded rod, which is rotatably connected to the upper surface of the machine tool body. The extrusion block is threaded to the outside of the threaded rod, and a limit rod is fixedly connected to the machine tool body, with the limit rod and the movable block being connected through each other.

[0011] Furthermore, the machine tool body has a sliding groove inside, and a movable block is slidably connected inside the sliding groove. An abutment rod is fixedly connected to the inner side of the movable block, and the movable block is fixedly connected to the protective cover.

[0012] Furthermore, the left and right sides of the extrusion block are both inclined, and the sides of the extrusion block abut against the end of the abutment rod.

[0013] Furthermore, a second spring is fixedly connected to the inner side of the lower end of the movable block and the interior of the slide groove. The movable block and the slide groove form an elastic structure through the second spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A protective cover is installed on both sides of the processing area. The protective cover can block water splashes and workpiece debris during processing, thereby preventing water, debris and other impurities from splashing randomly.

[0016] 2. The placement table is placed above the machine tool body. It is engaged with the docking slot on the machine tool body by connecting rod, which can realize the quick installation of the placement table. When the placement table is worn or damaged, the position of the docking rod can be adjusted to quickly disassemble and replace the placement table, which further improves the service life of the wire EDM machine tool.

[0017] 3. Manually pull the pull plate, which will simultaneously move the connecting rod upwards, thus completing the disassembly of the placement platform. When no force is applied to the pull plate, the pull plate, driven by the elastic force of the first spring, will drive the connecting rod to slide steadily downwards along the side plate and return to its original position, thus completing the installation of the placement platform. The position of the connecting rod can be adjusted by changing the position of the pull plate to meet different usage requirements.

[0018] 4. Rotate the threaded rod, which will drive the extrusion block to move vertically in sync. At this time, the inclined edge of the extrusion block can abut against the extrusion abutment rod, which will cause the abutment rod to drive the movable block to move laterally. The lateral movement of the movable block can simultaneously drive the two sets of protective covers to move in position. At this time, the distance between the two sets of protective covers can be adjusted as needed to adapt to the processing requirements of different workpieces.

[0019] 5. When the movable block moves upward, it can move along the limit rod. The limit rod can prevent the movable block from deflecting during movement. When the abutment rod is not under force, the movable block can move and reset under the drive of the elastic force of the second spring, which facilitates the subsequent position adjustment of the two sets of protective covers.

[0027] 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.

[0028] Example 1: As Figure 1 and Figure 5 The technical solution shown is provided by the present utility model as follows: A wire cutting machine tool with a protective structure is disclosed, which includes a protective cover 2 to prevent water, debris and other impurities from splashing randomly: a placement platform 3 is provided on the upper surface of the machine tool body 1, and protective covers 2 for preventing splashing are symmetrically arranged on the left and right sides above the machine tool body 1. The protective covers 2 are located on the left and right sides of the processing area. The protective covers 2 can block water and workpiece debris splashed during processing, thereby preventing water, debris and other impurities from splashing randomly.

[0029] Example 2: Figure 1 , Figure 2 , Figure 5 and Figure 6 The technical solution shown herein provides the following technical solution: A wire cutting machine tool with a protective structure, disclosing an adjustment mechanism, through which the distance between two sets of protective covers 2 can be adjusted: an adjustment mechanism is provided between the rear side of the protective cover 2 and the machine tool body 1, and the position adjustment of the protective cover 2 is achieved by the movement of the extrusion block 8 contained therein; the adjustment mechanism includes a threaded rod 7, the threaded rod 7 is rotatably connected to the upper surface of the machine tool body 1, and the extrusion block 8 is threadedly connected to the outside of the threaded rod 7, and the machine tool body 1... A limiting rod 13 is fixedly connected and is connected through the movable block 11. A slide groove 10 is provided inside the machine tool body 1, and the movable block 11 is slidably connected inside the slide groove 10. An abutment rod 9 is fixedly connected to the inner side of the movable block 11. The movable block 11 is also fixedly connected to the protective cover 2. The left and right sides of the extrusion block 8 are inclined, and the side of the extrusion block 8 abuts against the end of the abutment rod 9. A second spring 12 is fixedly connected to the inner side of the lower end of the movable block 11 and the interior of the slide groove 10. The movable block 11 and the slide groove 10 form an elastic structure through the second spring 12.

[0030] Rotating the threaded rod 7 causes the extrusion block 8 to move vertically in sync. At this time, the inclined side of the extrusion block 8 can abut against the extrusion abutment rod 9, causing the abutment rod 9 to drive the movable block 11 to move laterally. The lateral movement of the movable block 11 can simultaneously drive the two sets of protective covers 2 to move in position. At this time, the distance between the two sets of protective covers 2 can be adjusted as needed to adapt to the processing requirements of different workpieces. When the movable block 11 moves upward, it can move along the limit rod 13. The limit rod 13 can prevent the movable block 11 from deflecting during movement. When the abutment rod 9 is not under force, the movable block 11 can move and reset under the drive of the elastic force of the second spring 12, which facilitates the subsequent position adjustment of the two sets of protective covers 2.

[0031] Example 3: Figure 2 , Figure 3 and Figure 4 The present invention provides the following technical solution: a wire cutting machine tool with a protective structure, which discloses a connecting rod 5, through which the placement table 3 can be quickly installed: a side plate 14 is fixedly connected to the side of the placement table 3, and a connecting rod 5 is slidably connected to the side plate 14, and a pull plate 4 is fixedly connected to the upper end of the connecting rod 5, and a first spring 6 is fixedly connected between the lower surface of the pull plate 4 and the upper surface of the side plate 14, the lower end of the connecting rod 5 is engaged and connected to the corresponding connecting groove on the machine tool body 1, and the connecting rods 5 are evenly distributed laterally about the side plate 14, and the pull plate 4 forms a sliding structure with the side plate 14 through the first spring 6.

[0032] The placement table 3 is placed above the machine tool body 1. It engages with the docking rod 5 through the docking slot on the machine tool body 1, enabling quick installation of the placement table 3. When the placement table 3 is worn or damaged, it can be quickly disassembled and replaced by adjusting the position of the docking rod 5, further improving the service life of the wire cutting machine tool. Manually pulling the pull plate 4 will simultaneously move the docking rod 5 upward, thus completing the disassembly of the placement table 3. When no force is applied to the pull plate 4, the pull plate 4, driven by the elastic force of the first spring 6, can drive the docking rod 5 to slide down stably and return to its original position along the side plate 14, thus completing the installation of the placement table 3. The position of the docking rod 5 can be adjusted by changing the position of the pull plate 4 to meet different usage requirements.
