Description

Technical Field

[0001] This utility model relates to the field of wear-resistant and mark-free bending mold technology, and in particular to a wear-resistant and mark-free bending mold. Background Technology

[0002] This utility model discloses a seamless bending die according to Chinese Patent No. CN213763530U, including an upper die and a lower die. The upper die is fixedly installed on the bottom surface of an upper fixed plate, and the lower die is fixedly installed on the upper surface of a lower fixed plate. A bending head is provided on the bottom surface of the upper die. A bending groove is formed in the middle of the upper end of the lower die. Arc grooves are formed on both sides of the top of the bending groove in the middle of the lower die. Ball bearings are embedded at the bottom of the arc grooves, and bearings are provided in the middle of the arc grooves. The surface of the bearings contacts the ball bearings, and the bearings are movably installed inside the arc grooves through the ball bearings. This utility model provides bearings at the top of both sides of the bending die. When bending the metal, the metal comes into contact with the bearings, and the bearings then rotate inside the grooves by rolling. This prevents the metal material from directly contacting the edges of the bending die top, effectively preventing bending marks caused by the metal material contacting and being squeezed by the bending groove during bending, thus improving product quality.

[0003] The aforementioned prior art and related documents have the following technical problems:

[0004] The wear-resistant and non-marking bending dies commonly found in the current market require complex adjustment procedures when replacing the entire die, which is very inconvenient. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wear-resistant and scratch-free bending mold.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant and traceless bending mold, comprising a base, a second driver on the top of the base, a second adjusting screw on one side of the second driver, a first mold base on one side of the second adjusting screw, a connecting protrusion on one side of the second mold base, a pressing mold on the top of the first wear-resistant ceramic layer, and a second replacement pressing plate on one side of the second slot.

[0007] Preferably, the top of the first mold base is provided with a first wear-resistant ceramic layer, and the first wear-resistant ceramic layer is connected to the first mold base.

[0008] Preferably, the top of the second mold base is provided with a second wear-resistant ceramic layer, and the second wear-resistant ceramic layer is a mirror image of the first wear-resistant ceramic layer.

[0009] Preferably, the top of the pressing mold is provided with a connecting block, and the bottom of the connecting block is welded to the top of the pressing mold.

[0010] Preferably, a second slot is provided on one side of the pressing template, and the second slot is cut off.

[0011] Preferably, the pressing template has a first slot on one side, and the length of the first slot is the same as the length of the second slot.

[0012] Preferably, a first replacement pressure plate is provided on one side of the first slot, and the first slot is connected to the first replacement pressure plate groove.

[0013] Beneficial effects

[0014] In this invention, a first slot and a second slot are respectively provided on both sides of the pressing mold, and the first slot and the second slot are respectively connected to a first replacement pressing plate and a second replacement pressing plate. The first slot and the second slot can replace different pressing plates, so that workpieces of different thicknesses can be pressed during use, which can meet the processing needs of workpieces with various thicknesses. By simply replacing different first replacement pressing plates and second replacement pressing plates, there is no need to customize different complete sets of molds for workpieces of different thicknesses, which greatly reduces the types of molds and inventory costs. A set of molds can be used in a wider range of production scenarios, improving the utilization rate of equipment and mold resources. At the same time, operators can also quickly replace the corresponding pressing plates according to the changes in workpiece thickness during actual production. Compared with traditional molds that require complete replacement or complex adjustment device operations, this slot-type replacement pressing plate method is simpler and more efficient, which can significantly shorten production preparation time and product changeover time, improve production efficiency, and is especially suitable for small-batch, multi-variety production modes.

[0015] In this invention, a first wear-resistant ceramic layer and a second wear-resistant ceramic layer are respectively provided on the top of the first mold base and the second mold base. The ceramic material itself has high hardness. After the wear-resistant ceramic layers are provided on the top of the first and second mold bases, the friction between the workpiece and the mold base can be effectively resisted when the mold is undergoing a bending operation. The surface of the wear-resistant ceramic layer is smooth, and its microstructure is relatively flat. When bending metal workpieces, it can provide a relatively smooth contact surface for the workpiece. When the workpiece is bent and deformed under the action of the mold, the smooth ceramic layer can prevent scratches or indentations from being left on the workpiece surface. During the bending process, the deformation of the metal workpiece generates a large amount of heat, and the working temperature of the mold will rise. The wear-resistant ceramic layer has high high-temperature resistance and can maintain its physical and chemical properties stable in high-temperature environments.

[0016] In this invention, a second adjusting screw is provided on one side of the second driver, and the second adjusting screw is threadedly connected to the first die holder. This allows for precise fine-tuning of the height of the first die holder via the threaded connection between the second adjusting screw and the first die holder. During the use of the bending die, different workpiece materials, thicknesses, and bending process requirements may necessitate fine adjustments to the die's closing height. By rotating the second adjusting screw, the vertical position of the first die holder can be easily and accurately changed, ensuring that the gap between the die and the workpiece is optimal, thus guaranteeing bending accuracy and quality.

A connecting protrusion 16 is provided on one side of the seat 4. A pressing mold 10 is provided on the top of the first wear-resistant ceramic layer 3. A connecting block 11 is provided on the top of the pressing mold 10. The bottom of the connecting block 11 is welded to the top of the pressing mold 10. A second slot 15 is provided on one side of the pressing mold 10. The second slot 15 is cut off. A first slot 6 is provided on one side of the pressing mold 10. The length of the first slot 6 is the same as the length of the second slot 15. A first replacement pressure plate 12 is provided on one side of the first slot 6. The first slot 6 is connected to the first replacement pressure plate 12 by a groove. A second replacement pressure plate 13 is provided on one side of the second slot 15.

[0027] A first slot 6 and a second slot 15 are respectively provided on both sides of the pressing mold 10. The first slot 6 and the second slot 15 are respectively connected to a first replacement pressing plate and a second replacement pressing plate. The first slot 6 and the second slot 15 can replace different pressing plates, enabling the pressing of workpieces of different thicknesses during use, and adapting to the processing needs of workpieces of various thicknesses. By simply replacing different first and second replacement pressing plates, it is not necessary to customize different complete sets of molds for workpieces of different thicknesses, which greatly reduces the types of molds and inventory costs. A set of molds can be used in a wider range of production scenarios, improving the utilization rate of equipment and mold resources. At the same time, operators can also quickly change the corresponding pressing plates according to the changes in workpiece thickness during actual production. Compared to traditional molds that require complete replacement or complex adjustment, this slot-type replacement pressing method is simpler and more efficient, significantly shortening production preparation and product changeover times, and improving production efficiency. It is particularly suitable for small-batch, multi-variety production. A first wear-resistant ceramic layer 3 and a second wear-resistant ceramic layer 5 are respectively provided on the top of the first mold base 2 and the second mold base 4. The ceramic material itself has high hardness, ensuring that after the wear-resistant ceramic layers are placed on the top of the first mold base 2 and the second mold base 4, the friction between the workpiece and the mold base can be effectively resisted during bending operations. The surface of the wear-resistant ceramic layer is smooth, and its microstructure is relatively flat. When bending metal workpieces, it provides a relatively smooth contact surface. When the workpiece is bent and deformed under the action of the mold, the smooth ceramic layer can prevent scratches or indentations from being left on the workpiece surface. During the bending process, the deformation of the metal workpiece generates a large amount of heat, and the working temperature of the mold will rise. Meanwhile, the wear-resistant ceramic layer has high high-temperature resistance, maintaining stable physical and chemical properties under high-temperature environments. A second adjusting screw 14 is provided on one side of the second actuator 9, and the second adjusting screw 14 is threadedly connected to the first die holder 2. This allows for precise fine-tuning of the height of the first die holder 2 via the threaded connection between the second adjusting screw 14 and the first die holder 2. During the use of the bending die, different workpiece materials, thicknesses, and bending process requirements may necessitate fine adjustments to the die's closing height. By rotating the second adjusting screw 14, the vertical position of the first die holder 2 can be easily and accurately changed, ensuring that the gap between the die and the workpiece is optimal, guaranteeing bending accuracy and quality. Specific Implementation Example 2:

[0029] Reference Figure 1-4The system employs a multi-layered buffer material with varying elastic moduli on the surfaces of the first mold base 2 and the second mold base 4. The layer closest to the mold substrate uses a material with a higher elastic modulus to provide sufficient support and prevent mold deformation; the outer layer uses a soft, low-elastic-modulus material, such as nano-rubber. Furthermore, a special bonding process is used between these layers to form a unified, gradient elastic buffer layer. This allows for better absorption and dispersion of pressure during bending, protecting the workpiece surface at different depths, further reducing the probability of scratches and indentations, and simultaneously improving the durability of the buffer layer.

[0030] In summary:

[0031] The design employs a first slot 6 and a second slot 15 on both sides of the pressing mold 10. These slots are respectively connected to a first replacement pressing plate and a second replacement pressing plate. The first slot 6 and the second slot 15 can replace different pressing plates, enabling the pressing of workpieces of varying thicknesses and adapting to the processing needs of workpieces with diverse thicknesses. By simply replacing the first and second replacement pressing plates, there is no need to customize different complete molds for workpieces of different thicknesses, significantly reducing the variety of molds and inventory costs. A single mold can be used in a wider range of production scenarios, improving the utilization rate of equipment and mold resources. Simultaneously, operators can quickly replace the corresponding pressing plates according to changes in workpiece thickness during actual production. Compared to traditional molds that require complete replacement or complex adjustment operations, this slot-type replacement pressing plate method is simpler and more efficient, significantly shortening production preparation time and product changeover time, improving production efficiency, and is particularly suitable for small-batch, multi-variety production modes.

[0032] A first wear-resistant ceramic layer 3 and a second wear-resistant ceramic layer 5 are respectively provided on the top of the first mold base 2 and the second mold base 4. The ceramic material itself has high hardness, and after the wear-resistant ceramic layers are placed on the top of the first mold base 2 and the second mold base 4, the friction between the workpiece and the mold base can be effectively resisted when the mold is undergoing bending operations. The surface of the wear-resistant ceramic layer is smooth, and its microstructure is relatively flat. When bending metal workpieces, it can provide a relatively smooth contact surface for the workpiece. When the workpiece is bent and deformed under the action of the mold, the smooth ceramic layer can prevent scratches or indentations from being left on the workpiece surface. During the bending process, the deformation of the metal workpiece generates a large amount of heat, and the working temperature of the mold will rise. At the same time, the wear-resistant ceramic layer has high high-temperature resistance and can maintain its physical and chemical properties stable in high-temperature environments.

[0033] A second adjusting screw 14 is provided on one side of the second actuator 9. The second adjusting screw 14 is threadedly connected to the first die holder 2. This allows for precise fine-tuning of the height of the first die holder 2 via the threaded connection between the second adjusting screw 14 and the first die holder 2. During the use of the bending die, different workpiece materials, thicknesses, and bending process requirements may necessitate fine adjustments to the die's closing height. By rotating the second adjusting screw 14, the vertical position of the first die holder 2 can be easily and accurately changed, ensuring that the gap between the die and the workpiece is optimal, thus guaranteeing bending accuracy and quality.
