Description

Technical Field

[0001] This invention relates to the field of hardware manufacturing technology, and in particular to a continuous stamping die for hardware and its stamping method. Background Technology

[0002] In the manufacturing sector, hardware components are metal parts widely used in various products. They come in diverse shapes and structures and have a wide range of applications, including but not limited to home appliances, automobiles, and machinery. Stamping is a common processing method in the production of hardware components. It involves placing a sheet metal into a stamping die and using the force of the stamping press to cut the sheet metal into the desired shape.

[0003] However, in some cases, hardware parts with special shapes and structures require multiple processing steps, which traditional stamping methods struggle to meet. This is especially true for continuous stamping, where hardware parts undergo multiple steps, including drilling, trimming, stamping, bending, and cutting, demanding high precision and stability to ensure the quality and performance of the final product. Therefore, continuous stamping dies for hardware parts have emerged. Traditional continuous stamping dies present several challenges in manufacturing hardware parts, particularly those with complex shapes. During stamping, the elastic deformation of the metal material under stress often leads to uneven deformation of the outer periphery of the hardware part, with the central area experiencing greater force. These deformation problems can result in dimensional instability, appearance defects, and performance degradation, thus affecting product reliability and quality.

[0011] Preferably, the lower die assembly has a die for corresponding stamping.

[0012] A method for stamping metal parts, comprising stamping using a progressive die as described above, the method comprising:

[0013] Step 1: Using the guide hole stamping part and the half-fan-shaped process hole stamping part of the first punching mechanism, a guide hole and a first half-fan-shaped process hole are formed on both ends of the hardware part to be cut along its length. By forming guide holes and first half-fan-shaped process holes on both ends of the hardware part, the hardware part can be accurately positioned and guided in subsequent processes, so that the position of the hardware part is stable during the stamping process, avoiding positional deviation and skew, and improving the accuracy and consistency of processing.

Detailed Implementation

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See Figures 1-4 This embodiment provides a hardware component, which includes a hardware component body 10. The hardware component body 10 includes a first plane 11 and a second plane opposite to the first plane 11. A central rectangular groove 12 is formed in the middle of the hardware component body 10 by recessing from the first plane 11 to the second plane. An outer ring stamping groove 13 is formed on the outer periphery of the central rectangular groove 12. Side grooves 14 are provided on both sides of the hardware component body 10 in the width direction. A bending plane 15 is provided at the end of the hardware component body 10 in the width direction. The outer ring stamping groove 13, the side grooves 14, and the bending plane 15 are all recessed from the first plane 11 to the second plane. Arc-shaped notches 16 are provided at both ends of the hardware component body 10 in the length direction. The outer ring stamping groove 13 includes a large rectangular groove, a trapezoidal groove, and a small rectangular groove. The trapezoidal groove is mirror-imagely arranged on both sides of the large rectangular groove, and the small rectangular groove is arranged at the end of the trapezoidal groove away from the large rectangular groove. The large rectangular groove, the trapezoidal groove, and the small rectangular groove are integrally formed to form the outer ring stamping groove 13. In this embodiment, the large rectangular groove, the trapezoidal groove, and the small rectangular groove are used to better illustrate the structure of the outer ring stamping groove 13, so the outer ring stamping groove 13 is described separately. In fact, the outer ring stamping groove 13 is a one-piece structure. It should be noted that the groove depth of the central rectangular groove 12 is deeper than the groove depth of the outer ring stamping groove 13.

[0027] This embodiment provides a continuous stamping die for hardware parts, including an upper die assembly 31 and a lower die assembly 32 for progressive stamping of hardware parts. The upper die assembly 31 and the lower die assembly 32 are sequentially provided with a first punching mechanism, a second punching mechanism, an edge trimming mechanism, a stamping mechanism, an edge bending mechanism, an edge cutting mechanism and a blanking mechanism along the material conveying direction.

[0028] Specifically, the first punching mechanism includes a guide hole stamping component and a half-fan-shaped process hole stamping component. The guide hole stamping component is used to form a guide hole 21 at both ends of the hardware part along its length. The half-fan-shaped process hole stamping component is used to form a first half-fan-shaped process hole 22 at both ends of the hardware part along its length. The second punching mechanism is located at the rear end of the first punching mechanism. It includes two guide hole positioning pins and a half-fan-shaped process hole stamping component. The two guide hole positioning pins are used to fix the guide holes 21 when the hardware part strip reaches the second punching mechanism, thereby fixing the hardware part strip that has reached the second punching mechanism. The fixed hardware part strip can then be punched by the half-fan-shaped process hole stamping component to form a second half-fan-shaped process hole 23. At this time, the first half-fan-shaped process hole 22 and the second half-fan-shaped process hole 23 cooperate to form a complete fan-shaped process hole 24.

[0029] Specifically, the trimming mechanism includes two guide hole positioning pins and a trimming component. The guide hole positioning pins are used to limit the guide hole 21, thereby fixing the metal strip that reaches the trimming mechanism. The trimming component includes an I-shaped stamping component and extending stamping components located at both horizontal ends of the I-shaped stamping component and extending outward. The trimming component is used to cut the horizontal ends of the continuous metal strip to form a metal part.

[0030] The stamping mechanism includes two guide hole positioning pins, a central stamping part, an outer ring stamping part, and two side groove 14 stamping parts. The guide hole positioning pins are used to limit the guide hole 21, thereby fixing the hardware part that reaches the stamping mechanism. The central stamping part is used to stamp a central rectangular groove 12 on the cut hardware part. The outer ring stamping part is used to stamp an outer ring stamping groove 13 around the outside of the central rectangular groove 12. The side groove 14 stamping parts are used to stamp a side groove 14 on both sides of the hardware part in the horizontal direction. It should be noted that the central rectangular groove 12 is stamped first, followed by the outer ring stamping groove 13 and the side groove 14. After stamping is completed, the guide hole positioning pins at this location disengage from the guide hole 21, and then the stamped hardware part reaches the next edge bending mechanism.

[0031] The edge bending mechanism includes two guide hole positioning pins and two edge bending parts. The guide hole positioning pins are used to limit the guide hole 21 and thus fix the hardware that reaches the edge bending mechanism. The edge bending parts are used to bend the two sides of the hardware towards the concave direction of the central square hole to form a bending plane 15.

[0032] The edge trimming mechanism includes two arc-shaped stamping parts, which are used to trim the guide hole 21 and the fan-shaped process hole 24 to form an arc-shaped notch 16.

[0033] The feeding mechanism is used to feed hardware parts.

[0034] Preferably, the stamping mechanism further includes multiple hole-forming stamping parts for forming through holes in the hardware. Preferably, the upper die assembly 31 is provided with a guide sleeve, and the lower die assembly 32 is provided with a ball guide that can slide along the guide sleeve. Preferably, the lower die assembly 32 has a die for corresponding stamping. Thus, during the stamping of the above-mentioned stamping parts, the recess or cutting space of the hardware can be accommodated.

[0035] The continuous stamping die for hardware parts provided by this invention includes an upper die assembly 31 and a lower die assembly 32 for progressive stamping of hardware parts. The upper die assembly 31 and the lower die assembly 32 are sequentially arranged along the material conveying direction with a first punching mechanism, a second punching mechanism, an edge trimming mechanism, a stamping mechanism, an edge bending mechanism, an edge trimming mechanism, and a blanking mechanism. Employing continuous stamping, multiple processes of the hardware parts can be completed in a single stamping operation, significantly improving production efficiency. Secondly, by forming fan-shaped process holes at both ends of the hardware parts along their length, the distribution of stress on the metal material can be effectively altered, thereby reducing deformation problems and improving the shape stability of the hardware parts. Because the mechanical distribution during the stamping process is optimized, uneven deformation on the outer periphery can be reduced, thus improving the dimensional stability of the hardware parts, reducing appearance defects, improving the performance of the hardware parts, and ultimately improving product quality. Simultaneously, each mechanism includes a guide hole positioning pin for fixing the guide hole 21, ensuring that the hardware parts are fixed at each station, thereby improving the stability of the hardware parts during production. Therefore, this continuous stamping die for hardware parts improves the production efficiency of hardware parts, reduces the production cost per unit product, and improves the quality of hardware parts production, which helps to enhance the competitiveness of enterprises.

[0036] See Figure 1 This embodiment also provides a method for stamping hardware parts, which is used to stamp hardware parts using a continuous stamping die as described above. The method for stamping hardware parts includes:

[0037] Step 1: Using the guide hole stamping part and the semi-fan-shaped process hole stamping part of the first punching mechanism, a guide hole 21 and a first semi-fan-shaped process hole 22 are formed on both ends of the hardware part to be cut along the length direction. By forming the guide hole 21 and the first semi-fan-shaped process hole 22 on both ends of the hardware part, it is ensured that the hardware part can be accurately positioned and guided in subsequent processes, so that the position of the hardware part is stable during the stamping process, avoiding positional deviation and skew, and improving the accuracy and consistency of processing.

[0038] Step Two: The guide hole 21 is fixed using the guide hole positioning pin included in the second punching mechanism. Simultaneously, a second half-fan-shaped process hole 23 is formed at the metal strip through a half-fan-shaped process hole stamping part. The first half-fan-shaped process hole 22 and the second half-fan-shaped process hole 23 cooperate to form a complete fan-shaped process hole 24. The guide hole 21 is located at a predetermined distance on one side of the short arc of the fan-shaped process hole 24. Two arc-shaped connectors 26 connect the guide hole 21 to the metal body 10, forming the two radial sides of the fan-shaped process hole 24. This effectively enhances the structural stability of the metal part during stamping, reduces stress concentration in the central area, and thus reduces the risk of deformation during stamping. Only the arc-shaped connectors 26 are stretched during stamping, making the stamping more precise and stable, and optimizing the stamping process results.

[0039] Step 3: Use the guide hole positioning pin included in the trimming mechanism to fix the guide hole 21, and cut the horizontal ends of the continuous long metal part to form a single metal part. Specifically, as the metal strip continues to advance, the metal strip on one side of the advancing direction is cut first. When it advances to the next station, the rear end of the metal strip is cut, thus forming a single metal part at both ends. It should be noted that the ends of the metal strip perpendicular to its advancing direction are not cut, and both uncut ends form a long strip 25. The two ends of the cut metal part are partially connected to the corresponding long strip 25. During advancement, the long strip 25 moves forward continuously, and the individual metal parts formed by cutting move forward with the long strip 25.

[0040] Step 4: Use the guide hole positioning pin included in the stamping mechanism to fix the guide hole 21, and stamp a central rectangular groove 12, an outer ring stamping groove 13 surrounding the central rectangular groove 12, and side grooves 14 on both sides of the hardware in the horizontal direction on the cut hardware. Specifically, the central stamping part included in the stamping mechanism stamps a central rectangular groove 12 on the cut hardware, then the outer ring stamping part stamps an outer ring stamping groove 13 around the outside of the central rectangular groove 12, and then the side groove 14 stamping part stamps a side groove 14 on both sides of the hardware in the horizontal direction. After the stamping is completed, the guide hole positioning pin at this location disengages from the guide hole 21, and then the stamped hardware reaches the next edge bending mechanism.

[0041] Step 5: Fix the guide hole 21 using the guide hole positioning pin included in the edge bending mechanism, and then use the edge bending part to bend the two sides of the hardware part toward the recessed side of the central rectangular groove 12 to form the bending plane 15.

[0042] Step 6: Use the two arc-shaped stamping parts included in the edge trimming mechanism to trim the guide hole 21 and the fan-shaped process hole 24 in the hardware to form an arc-shaped notch 16;

[0043] Step 7: Use the blanking mechanism to blank the hardware parts.

[0044] Preferably, in step four, the stamping mechanism forms a predetermined number of through holes on the hardware.

[0045] Preferably, in step three, after the hardware is cut, its two ends in the length direction are connected to the two remaining long strips after the continuous long material of the hardware is cut.

[0046] The metal stamping method provided in this application adjusts the stress distribution during stamping by setting the guide hole 21 and the fan-shaped process hole in steps one and two. In particular, the fan-shaped process hole 24 connected by two arc-shaped connectors 26 reduces stress concentration in the central area, thereby effectively reducing the risk of deformation when stamping the middle of the metal part and significantly improving the shape and dimensional stability of the product. Through multiple processes in steps three to six, the metal part is finely processed and adjusted to ensure the accuracy and consistency of the guide hole 21, the central rectangular groove 12, the outer ring stamping groove 13, the side groove 14, etc., thereby improving the stability of stamping quality. Therefore, this metal stamping method has achieved significant beneficial effects in solving deformation problems, stabilizing quality, optimizing processes, and enhancing product consistency through innovative step design.

[0047] The above description is merely a specific embodiment of the present invention. However, those skilled in the art should understand that it is only illustrative, and the scope of protection of the present invention is defined by the appended claims. Therefore, equivalent variations made to the scope of the present invention still fall within the scope of the present invention.
