Description

Technical Field

[0001] This invention relates to the technical field, and more particularly to a hardware cold stamping die for rapid prototyping of metal sheets. Background Technology

[0002] Stamping is a manufacturing technology that uses the power of conventional or specialized stamping equipment to directly deform sheet metal within a die, thereby obtaining product parts with specific shapes, dimensions, and properties. During the manufacturing process, the design of the stamping die determines the quality of the stamped parts.

[0003] In general stamping processes, when metal materials are formed at room temperature, the flattening structure of traditional stamping dies causes rapid material hardening and an increase in flattening force. This leads to an imbalance of forces on both sides of the die, causing the upper die slide of the stamping press to tilt, damaging the press slide rails, and affecting the service life of the stamping press. Furthermore, the die has multiple forming stations, requiring frequent maintenance of both the male and female dies, resulting in low equipment uptime. During stamping trials, it was found that once compressed to more than 50%, the hardness increases linearly, reaching 10 times the material's strength, making further flattening very difficult and causing uneven thickness, affecting production quality. To solve these problems, this invention proposes a hardware cold stamping die for rapid forming of metal sheets. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed following the word and its equivalents, but do not exclude other elements or objects.

[0029] Example 1

[0030] To address the problems existing in the prior art, embodiments of the present invention provide a hardware cold stamping die for rapid prototyping of metal sheets, such as... Figure 1 As shown, the metal cold stamping die used for rapid prototyping of metal sheets in this embodiment can achieve self-adjustment, so that the stamping die in direct contact with the formed part always remains horizontal, thereby ensuring that the thickness of the formed part produced by stamping is consistent and improving the yield.

[0031] Specifically, the metal sheet rapid forming hardware cold stamping die includes an upper die 1 and a lower die 2, and a movable die 4 disposed between the upper die 1 and the lower die 2. A balance sensor 6 is provided on the upper surface of the movable die 4, and M balance adjustment mechanisms 5 are provided on the upper surface of the balance sensor 6. N push cylinders 3 are provided on the lower surface of the lower die 2. The push cylinders 3 are interconnected with the balance adjustment mechanisms 5, and the number of balance adjustment mechanisms 5 is matched with the number of push cylinders 3. During operation, the balance sensor 6 is used to sense the posture of the movable die 4. When the balance sensor 6 detects a signal that the movable die 4 is tilted in a first direction, it will drive the balance adjustment mechanism 5 in the tilt direction to adjust the movable die 4 so that the movable die 4 is adjusted to a horizontal position. Here, M and N are both positive integers greater than or equal to 3.

[0032] In practice, the number of balance adjustment mechanism 5 and push cylinder 3 remains consistent; they can be set to 3, 4, or more. Figure 1 In the example, the number of balance adjustment mechanism 5 and push cylinder 3 is set to 4.

[0033] Furthermore, such as Figure 2As shown, the balance adjustment mechanism 5 includes an adjustment box 51 fixedly connected to the drive end of the push cylinder 3. An adjustment component 54 is mounted on the adjustment box 51, and the drive end of the adjustment component 54 is connected to the upper surface of the base plate 53. The base plate 53 is fixedly connected to the upper surface of the balance sensor 6. During operation, while maintaining the position of the push cylinder 3, the relative position between the base plate 53 and the adjustment box 51 can be adjusted via the adjustment component 54. This adjustment process changes the movable mold 4 from an inclined state to a horizontal state. It should be noted that the balance adjustment mechanism 5 can adjust the movable mold 4 individually or in combination; the adjustment principle remains the same and will not be elaborated further here.

[0034] Furthermore, such as Figure 2 and Figure 3 As shown, the balance adjustment mechanism 5 also includes a guide connection component 52 disposed between the adjustment box 51 and the base plate 53, and used to connect the adjustment box 51 and the base plate 53. The guide connection component 52 can provide guidance and support for the movement of the base plate 53 relative to the adjustment box 51. It should be noted that the guide connection component 52 can be made entirely of an elastic metal material, such as shape memory alloy, or it can be partially made of shape memory alloy, for example, the part connected to the base plate 53 can be made of shape memory alloy. The purpose of this is to prevent the deflection of the movable mold 4 relative to the guide connection component 52 from causing the equipment to break or be damaged under the action of shear force.

[0035] Specifically, the guide connecting assembly 52 includes a guide connecting rod 521, a guide connecting cylinder 522, and a guide connecting spring 523. The guide connecting rod 521 is movably inserted into the guide connecting cylinder 522, and the guide connecting spring 523 is wound around the outside of the guide connecting rod 521. The two ends of the guide connecting spring 523 are respectively fixedly connected to the side wall of the guide connecting rod 521 and the outer side wall of the guide connecting cylinder 522. In this example, the guide connecting rod 521 and the guide connecting cylinder 522 can be made of elastic material, or the lower end of the guide connecting rod 521 can be made of non-elastic material.

[0036] Furthermore, such as Figure 4As shown, the adjusting assembly 54 includes a support rod 541 movably inserted into the base plate of the adjusting box 51. The upper end of the support rod 541 is fixedly connected to the drive end of the adjusting cylinder 542. The base plate of the adjusting cylinder 542 is fixedly connected to the inner top wall of the adjusting box 51. A fixing rod 543 is fixedly connected to the base plate of the adjusting cylinder 542, and the fixing rod 543 is fixedly connected to the inner bottom wall of the adjusting box 51. During operation, the activation of the adjusting cylinder 542 will cause the support rod 541 to move upward or downward. Through the movement of the support rod 541, the distance between the base plate 53 and the adjusting box 51 can be adjusted.

[0037] Example 2

[0038] The second embodiment of the present invention is based on the previous embodiment, but with the difference of further including a positioning mechanism 7 disposed within the adjustment box 51. The positioning mechanism 7 is used for intelligent locking of the support rod 541, such as... Figure 5 and Figure 6 As shown.

[0039] Specifically, the positioning mechanism 7 includes a plurality of positioning slots 71 formed on the support rod 541, and a positioning rod assembly 72 that matches the positioning slots 71. The positioning rod assembly 72 is fixedly mounted on the connecting seat 73. A first cylinder arm 75 is fixedly connected to the lower end face of the connecting seat 73. A monitor 74 is provided on the connecting seat 73. The lower end of the first cylinder arm 75 is fixedly connected to the drive end of the first cylinder 76. The first cylinder 76 is fixedly connected to a second cylinder arm 77. The free end of the second cylinder arm 77 is fixedly connected to the drive end of the second cylinder 78. The second cylinder 78 is fixed to the inner bottom wall of the adjusting box 51 by a fixing seat 79.

[0040] During operation, after the support rod 541 adjusts the position of the base plate 53 relative to the adjustment box 51, that is, after the movable mold 4 is adjusted to a horizontal state, the second cylinder 78 is started. The start of the second cylinder 78 will carry the positioning rod assembly 72 into the positioning groove 71 through the second cylinder arm 77, thereby locking the current horizontal state of the movable mold 4.

[0041] In this embodiment, the positioning mechanism 7 has a reasonable structural design. Because the support rod 541 moves at inconsistent heights in the vertical direction, the positioning rod assembly 72 may not align with the positioning groove 71. To solve this problem, the monitor 74 monitors the position of the positioning rod assembly 72 and the positioning groove 71 in real time. When the positioning groove 71 and the positioning rod assembly 72 are not aligned, the first cylinder 76 is activated. The activation of the first cylinder 76 causes the positioning rod assembly 72 to move vertically via the first cylinder arm 75, ensuring that the positioning rod assembly 72 remains aligned with the positioning groove 71. It is worth noting that the up-and-down movement and left-and-right movement of the positioning rod assembly 72 can be simultaneous, or the up-and-down movement of the positioning rod assembly 72 can precede its left-and-right movement.

[0042] Furthermore, a plurality of the positioning grooves 71 are arranged on the same vertical line, the plurality of positioning grooves 71 are arranged at equal intervals, and there is a gap between two adjacent positioning grooves 71, the size of the gap being less than 0.3mm.

[0043] Furthermore, such as Figure 7 As shown, the positioning rod assembly 72 includes a first positioning rod 721 and a second positioning rod 722, and a first spring 723 disposed between the first positioning rod 721 and the second positioning rod 722 for connecting the first positioning rod 721 and the second positioning rod 722. The second positioning rod 722 is fixed to the connecting seat 73, and a movable groove is formed on the second positioning rod 722. An abutment rod 724 is fixedly connected to the side wall of the first positioning rod 721, and the free end of the abutment rod 724 extends into the movable groove. The sidewall is abutted against by several push rods 725. The push rods 725 are movably inserted into the second positioning rod 722, and a fastening ball 726 is fixedly connected to one end of the push rod 725 outside the movable groove. The fastening ball 726 is movably disposed in the shrinkage groove 727, which is opened on the second positioning rod 722. A second spring 728 is wound around the push rod 725. The two ends of the second spring 728 are respectively fixedly connected to the sidewall of the push rod 725 and the sidewall of the shrinkage groove 727.

[0044] In this embodiment, the positioning rod assembly 72 has a reasonable structural design. Through linkage, the positioning rod assembly 72 can be firmly fixed in the positioning groove 71, preventing the support rod 541 from shaking vertically relative to the positioning rod assembly 72 after positioning. During operation, when the left end of the first positioning rod 721 abuts against the left side wall of the positioning groove 71, as the positioning rod assembly 72 continues to move to the left, the abutting rod 724 will abut against the pushing rod 725, causing the fastening ball 726 to move to the outside of the contraction groove 727, so that the fastening ball 726 abuts against the side wall of the positioning groove 71.

[0045] Preferably, the number of fastening balls 726 is set to a plurality, and the plurality of fastening balls 726 are arranged in a ring at equal intervals.

[0046] Example 3

[0047] This embodiment is based on the previous embodiment, but with the difference of further including a swing mechanism 8 disposed between the adjusting component 54 and the base plate 53, and used for connecting the base plate 53 and the adjusting component 54, such as... Figure 8 As shown, the swing mechanism 8 enables the support rod 541 to swing relative to the base plate 53, avoiding shear force at the connection between the support rod 541 and the base plate 53, which could damage the equipment. This swing mechanism 8 is applicable when the upper mold 1 moves vertically relative to the lower mold 2, and when the push cylinder 3 moves the adjustment box 51 and the support rod 541 vertically. When the deflection posture of the movable mold 4 needs adjustment, the movable mold 4 will deflect the base plate 53 relative to the support rod 541. In this example, the swing mechanism 8 prevents damage to the equipment caused by shear force.

[0048] Specifically, such as Figure 9 As shown, the swing mechanism 8 includes a swing rod 81 fixedly connected to the adjustment assembly 54. The lower end of the swing rod 81 is fixedly connected to a swing ball 83. The swing ball 83 is movably disposed in the swing groove 84. The swing groove 84 is opened on the swing seat 82. The swing seat 82 is fixedly disposed on the base plate 53.

[0049] Example 4

[0050] This embodiment is based on Embodiment 3, but differs in that it further includes a fastening mechanism 9 disposed on the swing seat 82. The fastening mechanism 9 is used to fasten the swing ball 83 within the swing groove 84, as follows: Figure 10 As shown.

[0051] Specifically, the fastening mechanism 9 includes a fastening groove 92 formed on the swing seat 82 and communicating with the swing groove 84. A fastening plate 91 is movably disposed in the fastening groove 92. A fastening rod 93 is fixedly connected to the side wall of the fastening plate 91. The fastening rod 93 is movably inserted into the swing seat 82. An electromagnet 94 is fixedly connected to the free end of the fastening rod 93. The electromagnet 94 is movably disposed in a fixed cylinder 95. The fixed cylinder 95 is fixedly connected to the swing seat 82. A magnet block 96 is fixedly connected to the inner side wall of the fixed cylinder 95. During operation, when the deflection of the swing ball 83 relative to the swing groove 84 is determined, that is, when the movable mold 4 is in a horizontal position, the electromagnet 94 is de-energized. The magnetic attraction between the electromagnet 94 and the magnet block 96 disappears. At this time, under the push of the guide support assembly 97, the fastening plate 91 will move to the left, thereby forming a resistance against the swing ball 83 and fixing the swing ball 83 in the swing groove 84. It should be noted that during the adjustment of the movable mold 4, the electromagnet 94 is energized and generates magnetism. Under the action of magnetic attraction, the fastening plate 91 will move to the right and disengage from the swing ball 83.

[0052] Furthermore, such as Figure 10 As shown, the fastening mechanism 9 further includes a guide support assembly 97 disposed between the electromagnet 94 and the magnet block 96, and used for connecting the electromagnet 94 and the magnet block 96. The guide support assembly 97 includes a guide support rod 971, a guide support cylinder 972, and a guide support spring 973. The guide support rod 971 is movably inserted into the guide support cylinder 972, and the guide support spring 973 is wound around the outside of the guide support rod 971. The two ends of the guide support spring 973 are respectively fixedly connected to the side wall of the guide support rod 971 and the outer side wall of the guide support cylinder 972.

[0053] In this embodiment, the guide support component 97 can both guide and support the movement of the electromagnet 94, and at the same time provide a reset force for the reset process of the electromagnet 94.

[0054] While embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of the present invention. Furthermore, the present invention described herein may have other embodiments and can be implemented or carried out in various ways.
