Description

Technical Field

[0001] The invention relates to the technical field of melt forming, and in particular to a melt forming mold. Background Art

[0002] A fuse is a simple and effective protective device, mainly used for circuit overload protection and short circuit protection. A fuse is provided with a melt inside, which is connected in series to the protected circuit. When a short circuit occurs in the circuit, the melt melts instantly, thereby disconnecting the circuit and playing a protective role. The production process of the melt usually involves the forging process of the melt forming.

[0003] In the related art, the forging process of melt forming is usually carried out in segmented forging, which results in poor dimensional matching accuracy of the segmented forging, multiple processing is required to obtain a multi-segment melt, and the consistency of the melt shape is poor, resulting in low melt production efficiency. Summary of the invention

[0004] In view of this, the present invention provides a melt forming mold to solve the problems of low efficiency and poor precision during multi-stage and multiple times of melt forming.

[0005] The present invention provides a melt forming mold, comprising:

[0006] The die body is formed with a stamping groove, a material receiving cavity suitable for receiving a material, and a guide groove extending along a first direction;

[0007] A pressing block assembly is at least partially disposed in the guide groove and is suitable for moving relative to the mold body along the first direction. The pressing block assembly is disposed on a side of the material holding cavity away from the stamping groove along the first direction. The pressing block assembly includes a plurality of pressing block units, and the plurality of pressing block units are arranged along the second direction. The pressing block unit includes a stamping portion and a pressing portion. The stamping portion is located at one end of the pressing block unit close to the stamping groove along the first direction, and the stamping portion matches the shape of the stamping groove. The pressing portion is located at one end of the pressing block unit away from the stamping portion along the first direction.

[0008] The movable pressing plate is suitable for moving along the second direction and sequentially pressing the pressing parts of the pressing block units, so that the pressing block units move along the first direction to punch the materials.

[0009] Beneficial effect: The present invention provides a melt forming die. During forging, the material is placed in the material holding cavity. The die body is formed with a stamping groove. The stamping groove is arranged on one side of the material holding cavity close to the die body along the first direction. A guide groove extending along the first direction is arranged on the other side. By arranging the guide groove extending along the first direction, a part of the pressing block assembly is accommodated in the guide groove and is suitable for moving relative to the die body along the first direction. The pressing block assembly includes a plurality of pressing block units. By arranging the pressing block units along the second direction, the melt can be moved according to the first direction. The number of briquetting units is used for multi-stage forming of different shapes. The briquetting unit includes a pressing part and a punching part. When forging, the punching part penetrates the material holding cavity and abuts against the material. The pressing part is moved along the second direction by the movable pressing plate and pressed in sequence. Moving and pressing in sequence can avoid the entire material being subjected to force at the same time to produce excessive deformation and thus cause failure states such as tearing. The external force applied to the pressing part by the movable pressing plate is transmitted to the punching part, so that the material acts on the punching groove and deforms, and finally the target melt is obtained, so that multiple stages of melt can be formed at one time.

[0010] In an optional embodiment, the stamping groove includes:

[0011] A first punching groove, a second punching groove and a third punching groove, wherein the first punching groove and the second punching groove are arranged adjacent to each other along the second direction, the third punching groove is arranged at at least one end of the punching groove along the second direction, and the number of the first punching groove and the second punching groove is multiple;

[0012] The pressing block unit comprises: a first pressing block and a second pressing block; the first pressing block has a first stamping portion at one end close to the stamping groove along the first direction, and the second pressing block has a second stamping portion at one end close to the stamping groove along the first direction, and the first pressing block is connected with the second pressing block in a matching manner; the first stamping portion and the second stamping portion match the shapes of the first stamping groove and the second stamping groove respectively;

The first pressing block and the second pressing block have a first stamping portion and a second stamping portion at one end close to the stamping groove along the first direction. The first stamping groove and the second stamping groove correspond to the first stamping portion and the second stamping portion and match in shape. By setting the third pressing block at at least one end of the pressing block assembly along the second direction, the third pressing block has a third stamping portion at one end close to the stamping groove along the first direction, so that the third stamping portion corresponds to the third stamping groove and matches in shape, which is conducive to obtaining different melt shapes according to work needs when forging the melt, and also meets the technical requirement that multiple sections of the melt can be forged at one time.

[0015] In an optional embodiment, the first punching portion is suitable for punching the material into a V-shaped structure, the second punching portion is suitable for punching the material into a flat planar structure, and the third punching portion is suitable for punching the material into a right-angle structure.

[0016] Beneficial effect: By setting different shapes of the first punching part, the second punching part and the third punching part, the shapes of the melt obtained after forging are different, which is conducive to better meeting the forging requirements of the melt required for work.

[0017] In an optional embodiment, part of the pressing block assembly moves relative to the mold body along the first direction in the guide groove and is elastically connected to the mold body. The pressing block assembly is squeezed by an external force along the first direction to generate a displacement along the first direction that varies with the magnitude of the external force.

[0018] Beneficial effect: After the moving component moves along the second direction and presses the pressing block component in sequence, the pressing block component is elastically connected to the mold body, so that after the pressing block component is displaced along the first direction by an external force, the pressing block component can be reset after the external force disappears, which is convenient for repeated forging, improves work efficiency and saves time costs.

[0019] In an optional embodiment, the guide groove includes:

[0020] A clamping groove extending along a first direction and arranged on an inner wall of the mold body close to the guide groove;

[0028] In an optional embodiment, the first pressure block is provided with a first protrusion in the direction opposite to the moving direction of the moving pressure plate; the second pressure block is provided with a second protrusion in the moving direction of the moving pressure plate, the first protrusion is provided in a direction relatively close to the moving pressure plate, and the second protrusion is provided in a direction relatively far away from the moving pressure plate, and the first protrusion and the second protrusion are abutted against each other.

[0029] Beneficial effect: By setting the first protrusion and the second protrusion, when the second pressure block rebounds due to the action of the spring, the first pressure block is subjected to the force of the second pressure block in the rebound direction, and the second protrusion is close to the stamping groove along the rebound direction relative to the first protrusion, so that during the resetting process of the second pressure block, the second protrusion can abut against the first protrusion, thereby driving the first pressure block to reset.

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0053] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] Fuse element is an important electrical component, mainly used for circuit protection. It achieves safety protection for equipment and lines by melting the fuse under overcurrent conditions. It is widely used in industrial electrical equipment, power systems and household appliances. The fuse achieves protection by heating and melting the fuse under short circuit or overload conditions. When the current exceeds the rated value, the fuse heats up rapidly and melts within a preset time, thereby cutting off the circuit and avoiding equipment damage or fire risk.

[0057] The forging technology of the melt directly determines the performance of the fuse. Usually, the melt is made of deformable thin sheets of conductive metal. In related technologies, the forging process of the melt forming is usually performed in sections, resulting in poor dimensional matching accuracy of the section forging. It takes multiple processing steps to obtain a multi-section melt, and the shape consistency of the melt is poor, resulting in low melt production efficiency.

[0058] The present invention provides a melt forming die. When forging is performed, the material is placed in a material containing cavity. A stamping groove is formed on the die body. The stamping groove is arranged on one side of the material containing cavity close to the die body along a first direction, and a guide groove extending along the first direction is arranged on the other side. By setting the guide groove extending along the first direction, a briquette assembly is partially accommodated in the guide groove and is suitable for moving relative to the die body along the first direction. The briquette assembly includes a plurality of briquette units. By arranging the briquette units along a second direction, the melt can be formed into multiple sections of different shapes according to the number of briquette units. The briquette units include a pressing part and a stamping part. When forging is performed, the stamping part penetrates the material containing cavity and abuts against the material. The pressing part is moved along the second direction by a movable pressing plate and pressed in sequence. The movement and sequential pressing can avoid the material as a whole being subjected to force at the same time to produce an excessive deformation amount and thus cause failure states such as tearing. The external force applied by the movable pressing plate is applied to the pressing part and transmitted to the stamping part, so that the material acts on the stamping groove and deforms, and finally a target melt is obtained, so that multiple sections of the melt can be formed at one time.

[0076] The first pressing blocks 211 are clamped with the clamping grooves 131 , and clamping spaces are formed between adjacent first pressing blocks. The clamping spaces are suitable for accommodating the second pressing blocks 212 .

[0077] The guide groove 13 is suitable for accommodating part of the pressing block assembly 2, and the corresponding snap-in groove 131 is suitable for accommodating the first pressing block 211.
