Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a hardware cold stamping die for rapid prototyping of metal plates. Background Art

[0002] Stamping is a production technology that uses the power of conventional or specialized stamping equipment to subject sheet metal to direct deformation forces within a die, thereby achieving a product part with a specific shape, size, and performance. During the manufacturing process, the design of the stamping die determines the quality of the resulting stamped part.

[0003] In a general stamping process, when metal materials are formed at room temperature, the flattening structure of the traditional stamping die will cause the material to harden extremely quickly, and the flattening force will increase, which will cause unbalanced forces on both sides of the die, resulting in tilting of both sides of the upper die slider of the stamping machine, damage to the slide rails of the stamping machine, and affect the service life of the stamping machine. Moreover, the die has many forming stations, the male and female dies need to be repaired frequently, and the equipment utilization rate is low. During the stamping trial process, it was found that once compressed to more than 50%, the hardness will rise linearly, reaching 10 times that of the raw material, and further flattening will be very difficult, and it will cause uneven thickness, affecting production quality.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs. The words "including" and similar words used in this article mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Example 1

[0018] In view of the problems existing in the prior art, the embodiment of the present invention provides a metal cold stamping die for rapid prototyping of metal sheets, such as Figure 1 As shown, the hardware cold stamping die 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 keeping the thickness of the formed part produced by stamping consistent and improving the yield rate.

[0019] 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 arranged between the upper die 1 and the lower die 2, a balance sensor 6 is provided on the upper end surface of the movable die 4, and M balance adjustment mechanisms 5 are provided on the upper end surface of the balance sensor 6, and N pushing cylinders 3 are provided on the lower end surface of the lower die 2, the pushing cylinders 3 and the balance adjustment mechanisms 5 are interconnected, and the number of the balance adjustment mechanisms 5 is matched with the number of the pushing cylinders 3. When working, the balance sensor 6 is used to sense the posture of the movable die 4. When the balance sensor 6 collects a signal that the movable die 4 is tilted in a first direction, it will drive the balance adjustment mechanism 5 in the tilting direction to adjust the movable die 4 so that the movable die 4 is adjusted to multiple horizontal positions, wherein M and N are both positive integers greater than or equal to 3.

[0020] In specific implementation, the number of the balance adjustment mechanism 5 and the pushing cylinder 3 is consistent, and can be set to 3, 4, or more. Figure 1 In this example, the number of the balance adjustment mechanism 5 and the pushing cylinder 3 is set to four.

[0021] Further, if Figure 2As shown, the balance adjustment mechanism 5 includes an adjustment box 51 fixedly connected to the driving end of the pushing cylinder 3, and an adjustment component 54 is provided on the adjustment box 51. The driving end of the adjustment component 54 is connected to the upper end surface of the bottom plate 53, and the bottom plate 53 is fixedly connected to the upper end surface of the balance sensor 6. During operation, while the position of the pushing cylinder 3 remains consistent, the relative position between the bottom plate 53 and the adjustment box 51 can be adjusted by the adjustment component 54, so that the adjustment process adjusts 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 alone, or several of them can adjust the movable mold 4 in coordination. The adjustment principle is the same and will not be repeated here.

[0022] Furthermore, if Figure 2 and Figure 3 As shown, the balance adjustment mechanism 5 further includes a guide connection assembly 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 provision of the guide connection assembly 52 can serve as a guide and support for the movement of the base plate 53 relative to the adjustment box 51. It should be noted that the guide connection assembly 52 can be entirely made of an elastic metal material, such as a memory alloy, or partially made of a memory alloy, such as the portion connected to the base plate 53. The purpose of such a provision is to prevent the deflection of the movable mold 4 relative to the guide connection assembly 52 from causing fracture or damage to the equipment due to shear force.

[0023] Specifically, the guide connection assembly 52 includes a guide connection rod 521, a guide connection cylinder 522, and a guide connection spring 523. The guide connection rod 521 is movably inserted into the guide connection cylinder 522, and the guide connection spring 523 is wound around the outside of the guide connection rod 521. The two ends of the guide connection spring 523 are respectively fixedly connected to the side wall of the guide connection rod 521 and the outer wall of the guide connection cylinder 522. In this embodiment, the guide connection rod 521 and the guide connection cylinder 522 can be made of an elastic material, or the lower end of the guide connection rod 521 can be made of no elastic material.

[0024] Furthermore, if Figure 4As shown, the adjustment assembly 54 includes a support rod 541 movably connected to the bottom plate of the adjustment box 51. The upper end of the support rod 541 is fixedly connected to the driving end of the adjustment cylinder 542. The bottom plate of the adjustment cylinder 542 is fixedly connected to the inner top wall of the adjustment box 51. The bottom plate of the adjustment cylinder 542 is fixedly connected to a fixing rod 543, and the fixing rod 543 is fixedly connected to the inner bottom wall of the adjustment box 51. During operation, the activation of the adjustment cylinder 542 will move the support rod 541 upward or downward. Through the movement of the support rod 541, the distance between the bottom plate 53 and the adjustment box 51 can be adjusted. Example 2

[0025] The second embodiment of the present invention is based on the previous embodiment, but differs in that it further comprises a positioning mechanism 7 provided in the adjustment box 51, and the positioning mechanism 7 is used to intelligently lock the support rod 541, such as Figure 5 and Figure 6 shown.

[0026] Specifically, the positioning mechanism 7 includes a plurality of positioning grooves 71 provided on the support rod 541, and a positioning rod assembly 72 matched with the positioning groove 71. The positioning rod assembly 72 is fixedly provided on a 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 driving end of the first cylinder 76. The first cylinder 76 is fixedly connected to the second cylinder arm 77. The free end of the second cylinder arm 77 is fixedly connected to the driving end of the second cylinder 78. The second cylinder 78 is fixed to the inner bottom wall of the regulating box 51 through a fixing seat 79.

[0027] During operation, after the support rod 541 adjusts the position of the base plate 53 relative to the adjustment box 51, that is, adjusts the movable mold 4 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, locking the current horizontal state of the movable mold 4.

[0028] The structural design of the positioning mechanism 7 in this embodiment is reasonable. Due to the inconsistent vertical movement height of the support rod 541, there is a problem that the positioning rod assembly 72 cannot align with the positioning slot 71. To solve this problem, the monitor 74 will monitor the position of the positioning rod assembly 72 and the positioning slot 71 in real time. When the positioning slot 71 and the positioning rod assembly 72 are not aligned, the first cylinder 76 will be activated. The activation of the first cylinder 76 will move the positioning rod assembly 72 in the vertical direction through the first cylinder arm 75, so that the positioning rod assembly 72 can always maintain alignment with the positioning slot 71. It is worth noting that the up and down movement and the left and right movement of the positioning rod assembly 72 can be performed simultaneously, or the up and down movement of the positioning rod assembly 72 can be performed before the left and right movement of the positioning rod assembly 72.

[0029] Furthermore, the plurality of positioning grooves 71 are arranged on the same vertical line, the plurality of positioning grooves 71 are arranged at equal distances, and there is a gap between two adjacent positioning grooves 71 , and the size of the gap is less than 0.3 mm.

[0030] Furthermore, if 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 provided between the first positioning rod 721 and the second positioning rod 722 and used to connect the first positioning rod 721 and the second positioning rod 722. The second positioning rod 722 is fixed on the connecting seat 73, and a movable groove is provided on the second positioning rod 722. A resisting rod 724 is fixedly connected to the side wall of the first positioning rod 721, and the free end of the resisting rod 724 extends into the movable groove, and the resisting rod 724 is fixedly connected to the side wall of the first positioning rod 721. The side wall is arranged to be in conflict with several push rods 725, and the push rod 725 is movably inserted into the second positioning rod 722, and the end of the push rod 725 located outside the movable groove is fixedly connected to a fastening ball 726, and the fastening ball 726 is movably set in the contraction groove 727, and the contraction groove 727 is opened on the second positioning rod 722. A second spring 728 is wound around the outside of the push rod 725, and the two ends of the second spring 728 are respectively fixedly connected to the side wall of the push rod 725 and the side wall of the contraction groove 727.

[0031] The positioning rod assembly 72 of this embodiment has a rational structural design. Through the linkage effect, the positioning rod assembly 72 can be fastened to the positioning slot 71, preventing the support rod 541 from shaking in the vertical direction relative to the positioning rod assembly 72 after positioning. During operation, when the left end of the first positioning rod 721 contacts the left side wall of the positioning slot 71, as the positioning rod assembly 72 continues to move leftward, the contact rod 724 will contact the push rod 725 and move the fastening ball 726 out of the retracting slot 727, causing the fastening ball 726 to contact the side wall of the positioning slot 71.

[0032] Preferably, there are a plurality of fastening balls 726 , and the fastening balls 726 are arranged in a ring shape with equal distances. Example 3

[0033] This embodiment is based on the previous embodiment, but differs in that it further includes a swing mechanism 8 disposed between the adjustment assembly 54 and the base plate 53 and used to connect the base plate 53 and the adjustment assembly 54. Figure 8 As shown, the swing mechanism 8 can make the support rod 541 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. The swing mechanism 8 is applicable when the upper mold 1 moves vertically relative to the lower mold 2, and when the cylinder 3 moves the adjustment box 51 and the support rod 541 vertically. When the deflection posture of the movable mold 4 needs to be adjusted, the movable mold 4 will deflect the base plate 53 relative to the support rod 541. The setting of the swing mechanism 8 in this example can avoid damage to the equipment caused by shear force.

[0034] Specifically, if Figure 9 As shown, the swing mechanism 8 includes a swing rod 81 fixedly connected to the adjusting component 54, and the lower end of the swing rod 81 is fixedly connected to a swing ball 83, and the swing ball 83 is movably set in a swing groove 84. The swing groove 84 is opened on a swing seat 82, and the swing seat 82 is fixedly set on the base plate 53. Example 4

[0035] This embodiment is based on the embodiment 3, but differs in that it further comprises a fastening mechanism 9 provided on the swing seat 82, and the fastening mechanism 9 is used to fasten the swing ball 83 in the swing groove 84. Figure 10 shown.

[0036] Specifically, the fastening mechanism 9 includes a fastening groove 92 formed on the swing seat 82 and connected to 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. The free end of the fastening rod 93 is fixedly connected to an electromagnet 94. The electromagnet 94 is movably disposed in a fixed cylinder 95 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 swing ball 83 is deflected relative to the swing groove 84, that is, when the movable mold 4 is adjusted to a horizontal position, the electromagnet 94 is deenergized, and 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 moves leftward, thereby forming a resistance against the swing ball 83, thereby 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 to generate magnetism, and under the action of the magnetic attraction, the fastening plate 91 will move to the right and separate from the swing ball 83 .

[0037] Further, if Figure 10 As shown, the fastening mechanism 9 also includes a guide support assembly 97 which is arranged between the electromagnet 94 and the magnet block 96 and is used to connect the electromagnet 94 and the magnet block 96. The guide support assembly 97 includes a guide support rod 971, a guide support tube 972 and a guide support spring 973. The guide support rod 971 is movably inserted into the guide support tube 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 tube 972.

[0038] In this embodiment, the guide support assembly 97 can not only play a guiding and supporting role for the movement of the electromagnet 94 , but also provide a reset force during the reset process of the electromagnet 94 .

[0039] 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 of these embodiments are possible. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention. Furthermore, the invention described herein is susceptible to other embodiments and may be practiced or implemented in a variety of ways.
