Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electrical appliance manufacturing, in particular to a novel manufacturing process of a fuse holder. Background Art
[0002] In the manufacturing field of fuse holders, welding is currently commonly used to manufacture components with unequal thicknesses. This traditional manufacturing process has many disadvantages: High manufacturing costs: To realize welding manufacturing, enterprises need to invest a lot of money to purchase a variety of equipment and tools, such as molds for parts molding, welding equipment for welding operations, and inspection tools and equipment for welding quality inspection. At the same time, they also need to purchase welding materials and equip tooling and inspection tools. In addition, the welding process is relatively complicated and requires professional operators, which undoubtedly increases labor costs.
[0003] Obvious product performance differences: Due to many uncertainties in the welding process, such as welding temperature, welding time, and the proficiency of welders, the produced parts have poor consistency in size, structure, resistance, etc. This performance difference will affect the overall stability and reliability of the fuse holder, which may have an adverse effect on the safety and performance of electrical equipment using the fuse holder. Summary of the invention
[0004] In view of the problems in the related art, the present invention proposes a new manufacturing process for a fuse holder to solve the problems of high cost and poor consistency in component performance caused by the traditional welding manufacturing process.
[0005] To this end, the specific technical solution adopted by the present invention is as follows: A novel manufacturing process for a fuse holder comprises the following steps: Integrated stamping and machining: The present invention adopts an integrated stamping process, which only requires one set of stamping dies, and the post-processing is performed after the stamping is completed. In the stamping stage, the raw materials are stamped into a specific shape and size through a carefully designed stamping pattern, so that the various parts of the fuse holder are initially formed. This integrated stamping process avoids the cumbersome process of separate processing and welding of multiple parts in the traditional process.
[0006] Specific process flow: First, according to the design requirements of the fuse holder, prepare suitable raw materials. Then, put the raw materials into the stamping die, apply pressure through the stamping equipment, and perform stamping operations according to the planning of the stamping layout, so that the raw materials are gradually formed into a blank close to the shape of the final product. Then, the stamped blank is post-processed, and the size and accuracy of the blank are further accurately adjusted through finishing processes such as cutting and grinding to make it fully meet the design standards of the fuse holder. Beneficial Effects of the Invention Reduce manufacturing costs: Compared with traditional welding processes, the present invention does not require welding equipment, welding materials, and related welding tooling and inspection tools, and reduces the number of molds, requiring only one set of stamping molds. At the same time, the simplified process also reduces the professional skill requirements for operators and reduces labor cost investment, thereby significantly reducing the manufacturing cost of the fuse holder.
[0007] Improve product performance consistency: The integration of stamping technology and post-process machining makes the fuse holder less affected by human factors and welding uncertainty during the manufacturing process. This ensures that the produced parts have high consistency in size, structure, resistance, etc., improves the overall stability and reliability of the fuse holder, and thus improves the safety and performance of electrical equipment using the fuse holder.

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings: Figure 1 It is a schematic diagram of a novel manufacturing process of a fuse holder of the present invention; Figure 2 This is a stamping layout diagram of a new manufacturing process for a fuse holder of the present invention; DETAILED DESCRIPTION
[0009] According to an embodiment of the present invention, a novel manufacturing process of a fuse holder is provided.
[0010] Raw material selection: According to the use environment, electrical performance requirements and mechanical strength requirements of the fuse holder, select suitable metal materials, such as copper alloy or aluminum alloy with good conductivity and certain mechanical strength. Ensure that the quality of raw materials meets relevant standards to avoid affecting product performance due to raw material quality problems.
[0011] Design and manufacturing of stamping dies: According to the design drawings of the fuse holder, design a set of accurate stamping dies. In the design process, full consideration is given to the optimization of the stamping pattern to improve the utilization rate of raw materials and stamping efficiency. High-precision processing equipment and advanced manufacturing technology are used to manufacture stamping dies to ensure the accuracy and reliability of the dies. Strict quality inspection is carried out on the manufactured dies to ensure that the dimensional accuracy and surface quality of the dies meet the design requirements.
[0012] Stamping operation: Put the selected raw materials into the debugged stamping equipment and perform stamping operation according to the preset stamping process parameters. During the stamping process, strictly control the parameters such as stamping pressure, stamping speed and stamping stroke to ensure that the shape and size of the stamped blank meet the requirements. At the same time, regularly inspect and maintain the stamping equipment and molds, and clean up the waste in the molds in time to ensure the smooth progress of the stamping operation.
[0013] Post-process machining: The stamped blank is transferred to the machining equipment and the machining operation is performed according to the final design size and precision requirements of the fuse holder. For example, a lathe is used to turn certain parts of the blank to achieve the specified diameter size; a milling machine is used to mill the blank to produce a specific shape and structure; a grinder is used to grind the surface of the blank to improve the surface finish. During the machining process, appropriate cutting tools and cutting parameters are used to ensure processing quality and efficiency.
[0014] Quality inspection: The fuse holder is inspected for quality at each key link in the manufacturing process. After stamping, check whether the shape and size of the blank meet the requirements and whether there are stamping defects such as cracks and deformation; after machining, the product's dimensional accuracy, surface quality, electrical performance, etc. are fully inspected. Use professional inspection equipment and inspection methods, such as calipers to measure dimensions, resistance testers to detect resistance, and appearance inspection equipment to check surface defects. For products that fail the inspection, timely analysis and processing are carried out to find out the reasons and take corresponding improvement measures.
[0015] Product packaging and storage: Clean the qualified fuse holders to remove impurities such as oil, iron filings, etc. on the surface. Then, choose appropriate packaging materials according to the characteristics of the product and customer needs, such as plastic bags, paper boxes, etc. to prevent the product from being damaged during transportation and storage. Store the packaged products in a dry and ventilated environment to avoid moisture and oxidation, etc., to ensure the stability of product quality.
[0016] The stamping layout consists of 1. punching round holes 2. blanking 3. blanking 4. pulling convex 5. pulling convex 6. punching characters L0GO 7. blanking 8. bending 9. bending 10. bending adjustment 11. dropping products 12. cutting waste.
[0017] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
