Description

Technical Field

[0001] This utility model relates to the field of wire cutting technology, specifically to a protective device for wire cutting of mold steel. Background Technology

[0002] Wire EDM, a high-precision and high-efficiency metal processing technology, is suitable for precision cutting of mold steel with complex shapes and fine structures. It uses a thin metal wire as an electrode wire and gradually removes the material by electrical pulse discharge in the working fluid, thus achieving non-contact processing.

[0003] When wire cutting mold steel, a U-shaped protective cover is usually installed in the cutting area to prevent metal chips, sparks, and coolant splashes from affecting operators or equipment. This cover isolates and shields the cutting area, providing some protection. However, existing U-shaped protective covers have relatively simple structures, usually placed directly on the workbench or held in place by their own weight, lacking dedicated fixing devices. This makes them prone to displacement, shifting, or vibration during the cutting process. Especially when cutting high-hardness materials like mold steel, the electrical discharge cutting process generates significant heat and coolant impact, and the machine tool vibrates frequently. The protective cover is easily dislodged by external forces, reducing its protective effect and even causing safety hazards. Frequent adjustments to the protective cover also affect operational efficiency.

[0004] In view of this, we propose a protective device for cutting mold steel wire. Utility Model Content

[0005] The purpose of this utility model is to provide a protective device for cutting mold steel wire. This protective device solves the problem that the existing U-shaped protective cover for cutting mold steel wire lacks a fixed structure, resulting in poor protective effect, increased safety hazards, and reduced operating efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A protective device for wire cutting of mold steel includes a machine body with a platform on the machine body for placing the mold steel to be cut. A protective mechanism is provided on the platform, comprising: a U-shaped protective plate positioned on top of the platform; a bottom receiving block fixedly connected to the top of the platform, with a top guide block fixedly connected to the outer wall of the U-shaped protective plate, the bottom of the top guide block being sloped, and a sloped surface on the inner wall of the bottom receiving block; and a rigid plate fixedly connected to the top of the bottom receiving block, with a spring on the outer wall of the rigid plate, the spring being movably fixedly connected to the outer wall of the rigid plate, and a positioning block fixedly connected to the other end of the spring, with a guide strip fixedly connected to the outer wall of the positioning block, the outer wall of the guide strip being slidably connected to the inner wall of the rigid plate; two of each of the bottom receiving block, top guide block, rigid plate, spring, positioning block, and guide strip are symmetrically arranged; and a disassembly mechanism is provided on the top guide block for easier disassembly of the protective mechanism.

[0008] Preferably, the machine base is provided with a U-shaped groove, which is used to insert a U-shaped protective plate.

[0009] Preferably, a cuboid plate is provided on the side of the guide bar away from the positioning block to limit the sliding of the guide bar, and the guide bar is a cuboid.

[0010] Preferably, the disassembly mechanism includes a limiting groove, which is formed on the positioning block. A second spring is provided on the inner wall of the top guide block. One end of the second spring is fixedly connected to the inner wall of the top guide block, and the other end of the second spring is fixedly connected to a connecting rod. A limiting block is fixedly connected to the outer wall of the connecting rod.

[0011] Preferably, the outer wall of the connecting rod is slidably connected to the inner wall of the top guide block for stable reciprocating sliding of the connecting rod.

[0012] Preferably, the outer wall of the connecting rod penetrates the hollow guide block, and the inner wall of the hollow guide block is slidably connected to the connecting rod.

[0013] Preferably, there are two of each of the limiting groove, spring 2, connecting rod, limiting block, and hollow guide block, and a U-shaped rod is fixedly connected to the top of each of the two connecting rods.

[0014] By employing the above technical solution, this utility model provides a protective device for cutting mold steel wire. It possesses at least the following beneficial effects:

[0015] 1. This utility model incorporates a protective mechanism. When the U-shaped protective plate is placed on the machine platform, the two sloping surfaces of the top guide block and the bottom receiving block guide the U-shaped protective plate to be inserted correctly, preventing it from tilting or misaligning. As the U-shaped protective plate moves downwards and is inserted into the bottom receiving block, the sloping surface of the top guide block first abuts against the positioning block, causing the positioning block to move towards the rigid plate by squeezing the spring until the positioning block no longer abuts against the top guide block. Then, under the action of the spring, the positioning block locks and limits the top guide block, making the U-shaped protective plate less likely to shift or loosen due to vibration or impact during use.

[0016] 2. This utility model features a disassembly mechanism. Two connecting rods can be moved simultaneously using a U-shaped rod. The connecting rod drives the limiting block downwards, causing it to first contact the positioning block. This compresses the spring and moves it towards the rigid plate until the limiting block no longer contacts the positioning block. At this point, under the action of the spring, the limiting block engages with the limiting groove, forming a double engagement that is more secure and has stronger vibration resistance. Furthermore, when it is necessary to release the limiting position, simply pull the connecting rod upwards. The connecting rod drives the limiting block to contact the inclined surface of the compression limiting groove, causing the positioning block to move towards the rigid plate, thus releasing the top guide block from the limiting block. This eliminates the need to bend over and pull the guide bar. Attached Figure Description

[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] Please see Figure 1 - Figure 8As shown, this utility model provides a technical solution: a protective device for cutting mold steel wire, including a machine body 1, which is a mold steel wire cutting device. A machine platform 2 is provided on the machine body 1 for placing the mold steel to be cut. A protective mechanism 3 is provided on the machine platform 2, comprising: a U-shaped protective plate 32, which is disposed on the top of the machine platform 2; a bottom receiving block 33, which is fixedly connected to the top of the machine platform 2; and a top guide block 34, whose bottom is sloped, is fixedly connected to the outer wall of the U-shaped protective plate 32. The inner wall of the receiving block 33 has a slope. When the U-shaped protective plate 32 is placed on the machine base 2, the slope of the top guide block 34 will engage with the inner wall of the bottom receiving block 33. These two slopes will naturally align and guide the U-shaped protective plate 32 to be inserted correctly, avoiding skewness or misalignment. A rigid plate 35 is fixedly connected to the top of the bottom receiving block 33. A spring 36 is provided on the outer wall of the rigid plate 35. The movement of the spring 36 is fixedly connected to the outer wall of the rigid plate 35. A positioning block 37 is fixedly connected to the other end of the spring 36. A guide is fixedly connected to the outer wall of the positioning block 37. The outer wall of guide bar 38 is slidably connected to the inner wall of rigid plate 35; when the top guide block 34 is inserted into the bottom receiving block 33 along with the U-shaped protective plate 32, the slope of the top guide block 34 first abuts against the positioning block 37, causing the positioning block 37 to compress the spring 36 and move towards the rigid plate 35 until the positioning block 37 no longer abuts against the top guide block 34. Then, under the action of the spring 36, the positioning block 37 locks and limits the top guide block 34, making the U-shaped protective plate 32 less likely to shift or loosen due to vibration or impact during use; when the U-shaped protective plate 32 is inserted into the bottom receiving block 33, the top guide block 34 is inserted into the bottom receiving block 33. When the protective plate 32 is inserted into the bottom receiving block 33, if there is only a positioning and limiting structure on one side, the force is easily uneven, which may cause the protective plate to loosen on one side and be tightly stuck on the other side. Therefore, the bottom receiving block 33, the top guide block 34, the rigid plate 35, the spring 36, the positioning block 37, and the guide strip 38 are all symmetrically arranged in twos. After the two structures are symmetrically arranged, the insertion process and the limiting process can be carried out simultaneously on both sides, forming a double-sided constraint to prevent tilting and shaking. The top guide block 34 is provided with a disassembly mechanism 4, which is used to more conveniently disassemble the limiting of the protective mechanism 3.

[0029] The machine base 2 is provided with a U-shaped groove 31, which is used to insert the U-shaped protective plate 32. It is equivalent to the installation port and is used to stabilize the U-shaped protective plate 32. A cuboid plate is provided on the side of the guide bar 38 away from the positioning block 37. It is used to limit the sliding of the guide bar 38 and also makes it easy to release the limit by pulling the guide bar 38 by hand. The guide bar 38 is a cuboid.

[0030] The disassembly mechanism 4 includes a limiting groove 41, which is formed on the positioning block 37. A second spring 42 is provided on the inner wall of the top guide block 34. One end of the second spring 42 is fixedly connected to the inner wall of the top guide block 34, and the other end of the second spring 42 is fixedly connected to a connecting rod 43. A limiting block 44 is fixedly connected to the outer wall of the connecting rod 43. The connecting rod 43 drives the limiting block 44 downward. The limiting block 44 first abuts against the positioning block 37, squeezing the first spring 36 to move towards the rigid plate 35 until the limiting block 44 no longer abuts against the positioning block 37. At this time, under the action of the first spring 36, the limiting block 44 engages with the limiting groove 41, forming a double engagement, which is more secure and has stronger vibration resistance. When it is necessary to release the limiting, simply pull the connecting rod 43 upward. The limiting block 44 abuts against the inclined surface of the compression limiting groove 41, causing the positioning block 37 to compress the spring 36 and move towards the rigid plate 35. This releases the top guide block 34 from the limiting block 44, eliminating the need to bend over and pull the guide bar 38. The outer wall of the connecting rod 43 is slidably connected to the inner wall of the top guide block 34 for stable reciprocating sliding of the connecting rod 43. The outer wall of the connecting rod 43 passes through the hollow guide block 45, and the inner wall of the hollow guide block 45 is slidably connected to the connecting rod 43. The limiting groove 41, the second spring 42, the connecting rod 43, the limiting block 44, and the hollow guide block 45 are all symmetrically arranged in twos. The top of each of the two connecting rods 43 is fixedly connected to a U-shaped rod 46, so that only the U-shaped rod 46 needs to be pulled to pull both connecting rods 43 at the same time, making it more convenient to release the limit.

[0031] In the use of this utility model, a protective device for wire cutting of mold steel is provided. The mold steel to be cut is placed on the machine base 2, ensuring its stable position. The U-shaped protective plate 32 is placed on the machine base 2. The slope of the top guide block 34 will insert into the inner wall of the bottom receiving block 33. These two slopes will naturally align and guide the U-shaped protective plate 32 to be inserted correctly, avoiding skewness or misalignment. When the top guide block 34 is inserted into the bottom receiving block 33 as the U-shaped protective plate 32 moves downward, the slope of the top guide block 34 first abuts against the positioning block 37, causing the positioning block 37 to compress the spring 36 and move towards the rigid plate 35 until the positioning block 37 no longer abuts against the top guide block 34. Then, under the action of the spring 36, the positioning block 37 locks and limits the top guide block 34, making the U-shaped protective plate 32 less likely to shift or loosen due to vibration or impact during use.

[0032] The two connecting rods 43 can be moved simultaneously by the U-shaped rod 46. The connecting rod 43 drives the limiting block 44 downward. The limiting block 44 first abuts against the positioning block 37, compressing the spring 36 and moving towards the rigid plate 35 until the limiting block 44 no longer abuts against the positioning block 37. At this time, under the action of the spring 36, the limiting block 44 engages with the limiting groove 41, forming a double engagement, which is more secure and has stronger vibration resistance. When it is necessary to release the limit, simply pull the connecting rod 43 upward. The connecting rod 43 drives the limiting block 44 to abut against the inclined surface of the limiting groove 41, causing the positioning block 37 to compress the spring 36 and move towards the rigid plate 35, so that the top guide block 34 and the limiting block 44 are released from the limit, without having to bend over to pull the guide strip 38.
