Abstract
Description
[Technical Field]
[0001] The present invention relates to automatic riveting in a metal stamping die, specifically to a stamping and riveting mechanism that integrates a first object riveting mechanism into a stamping die, thereby achieving stamping and riveting of a first object and a second object together during the stamping process. [Background technology]
[0002] Conventional riveting methods are roughly divided into methods using a riveting device and methods using a stamping device. Below, the drawbacks of the two conventional methods will be explained using the mutual riveting of a nut and a plate as an example, but the objects to be riveted together are not limited to a nut and a plate.
[0003] Riveting equipment has strict plate thickness requirements and is not suitable for thin materials. If the plate thickness is increased according to the riveting surface, production costs will increase significantly. In addition, different plate thicknesses will require different rivet nut structural parameters, which not only takes time to set up but also increases production and quality control costs.
[0004] For press equipment, the stamping and riveting steps include: positioning on the mold - inserting the nut - placing the plate - mutual press-fit riveting - finished product. The disadvantages of stamping equipment are that the steps are complicated, the nuts and plates are manually placed, which is not only slow, but also prone to placement errors, resulting in defective products and low production efficiency.
[0005] Therefore, how to develop a "stamping and riveting mechanism" that can rivet a first object and a second object together in a stamping process, has a simple and fast workflow, stable quality, and reduces production costs, has become a problem that those skilled in the art must solve.

[Figure 10] 1 is a structural diagram illustrating an embodiment of the present invention in which a first object and a second object are installed; FIG. DETAILED DESCRIPTION OF THE INVENTION
[0016] Referring to FIG. 1, a stamping and riveting tool 100 provided by the present invention includes a first stamping member 10 and a second stamping member 20 .
[0017] The first stamping member 10 and the second stamping member 20 are arranged one above the other parallel to the first direction F1, and the first stamping member 10 is installed above the second stamping member 20. The first stamping member 10 can move relatively parallel to the first direction F1 and the second stamping member 20.
[0018] The first stamping member 10 is placed on a first object 91, and the second stamping member 20 is placed on a second object 92, and the first stamping member 10 and the second stamping member 20 are stamped together, and the first object 91 and the second object 92 are riveted together to form a finished product.
[0019] The shapes of the first object 91 and the second object 92 may be die stamping parts that can be arbitrarily riveted together according to actual needs, for example, the first object 91 may be a nut, and the second object 92 may be a plate. Usually, the first object 91 and the second object 92 are made of metal.
[0020] The first stamping member 10 includes a first stamping stand 11, a stamping head 12, an unloading plate 13, a plurality of movable members 14, a plurality of guide columns 15, and a feeding device 16. Typically, the materials of the stamping stand 11, the stamping head 12, the unloading plate 13, the plurality of movable members 14, the plurality of guide columns 15, and the feeding device 16 are steel, hard alloy, steel-bonded hard alloy, zinc-based alloy, low-melting-point alloy, aluminum bronze, or polymer material.
[0021] The stamping head 12 has a first upper end 121 and a first bottom end 122 facing each other. The first upper end 121 is mounted on the first stamping stand 11, and the first bottom end 122 faces the second stamping member 20 in a direction parallel to the first direction F1.
[0022] The unload plate 13 is installed below the first stamping stand 11 .
[0023] The movable member 14 has a second upper end 141 and a second lower end 142 facing each other. The movable member 14 is movably installed through the first stamping stand 11 in parallel to the first direction F1. The second lower end 142 is connected to the unload plate 13. This allows the first stamping stand 11 to move relatively in the first direction F1 and parallel to the unload plate 13.
[0024] The second bottom end 142 and the unload plate 13 may be connected by screws, for example, or the unload plate 13 may be fixed to the second bottom end 142 by welding or other methods.
[0025] The guide column 15 has a third upper end 151 and a third bottom end 152 facing each other. The third upper end 151 is mounted on the first stamping stand 11, and the third bottom end 152 faces the second stamping member 20. The guide column 15 is mounted parallel to the first direction F1 and penetrates the unload plate 13 as much as possible.
[0026] 2 and 3, the supply device 16 includes a base 161, a plurality of swinging members 162, a plurality of elastic members 163, a plurality of positioning members 164, a plurality of steel balls 165, a supply stand 166, a first detection member 167, and a second detection member 168.
[0027] The base 161 and the stamping head 12 are installed on the same axis C. The base 161 is installed on the unload plate 13. The base 161 has a first through-hole 1611. The first through-hole 1611 penetrates the base 161 parallel to the first direction F1. The first bottom end 122 of the stamping head 12 can enter the first through-hole 1611 and move within the first through-hole 1611 parallel to the first direction F1.
[0028] Each swinging member 162 is mutually assembled with an elastic member 163, a positioning member 164, and a steel ball 165. The number of swinging members 162, elastic members 163, positioning members 164, and steel balls 165 is not limited, but it is preferable that they be arranged symmetrically around the first through-hole 1611. For example, as shown in FIGS. 1 and 2, they are arranged symmetrically on both sides of the first through-hole 1611.
[0029] The swinging member 162 is pivotally mounted on the base 161 by a rotation shaft 1623 , and has a first swinging arm 1621 and a second swinging arm 1622 symmetrically opposed to each other with respect to the rotation shaft 1623 , and the first swinging arm 1621 is located above the second swinging arm 1622 .
[0030] The elastic member 163 is installed in the base 161, and the elastic direction of the elastic member 163 is parallel to the second direction F2, and the elastic member 163 has opposite ends parallel to the elastic direction that abut against the first swing arm 1621 and the base 161, respectively. The second direction F2 and the first direction F1 are perpendicular to each other.
[0031] The positioning member 164 is installed in the base 161 and has a first end 1641 and a second end 1642 that face each other and are parallel to the second direction F2. The first end 1641 allows the first through-hole 1611 to enter or exit, and the second end 1642 is connected to the second swing arm 1622.
[0032] The steel ball 165 is installed in the base 161 and is located between the rotation shaft 1623 and the positioning member 164. The steel ball 165 can move between an open position and a pressed position. Figure 2 shows the open position, where a part of the steel ball 165 protrudes into the first through-hole 1611. Figure 3 shows the pressed position, where the steel ball 165 retracts from the first through-hole 1611.
[0033] Referring to FIG. 2, when the stamping head 12 is not in contact with the steel ball 165, the steel ball 165 is in an open position, and the elastic force of the elastic member 163 pushes the first swing arm 1621 outward, and the second swing arm 1622 causes the first end 1641 of the positioning member 164 to enter the first through-hole 1611.
[0034] 3, when the stamping head 12 moves downward in parallel with the first direction F1 and contacts the steel balls 165, it pushes each steel ball 165 outward to a pressing position, causing the steel balls 165 to exit from the first through-hole 1611. The steel balls 165 push and swing the second swing arm 1622, causing the first end 1641 of the positioning member 164 to exit from the first through-hole 1611. The first swing arm 1621 compresses the elastic member 163.
[0035] The supply stand 166 is installed at the bottom of the base 161, and has a second through-hole 1661. The second through-hole 1661 penetrates the supply stand 166 parallel to the first direction F1. A protrusion 1662 is provided on the bottom of the supply stand 166.
[0036] It is preferable that the projection range of the first through-hole 1611 of the base 161 falls within the projection range of the second through-hole 1661 of the supply stand 166, and that the projection range of the first through-hole 1611 and the projection range of the second through-hole 1661 are equal.
[0037] The first detection member 167 is installed inside the second penetration portion 1661 and detects whether or not the first object 91 is present inside the second penetration portion 1661 .
[0038] The second detection member 168 is installed inside the first penetrating portion 1611 and detects whether the first object 91 is positioned.
[0039] When the first detection member 167 detects that the first object 91 is present in the second penetration portion 1661 or the second detection member 168 detects that the first object 91 is present in the first penetration portion 1611, a signal is sent to a servo system (not shown) to control the stamping and riveting mechanism to continue the subsequent operation.
[0040] 1, the second stamping member 20 includes a second stamping stand 21 and a riveting stand 22. Typically, the second stamping stand 21 and the riveting stand 22 are made of metal materials such as steel, hard alloy, steel-bonded hard alloy, zinc-based alloy, low-melting-point alloy, aluminum bronze, polymer material, etc.
[0041] The second stamping stand 21 has a third through-hole 211 and a complex guide hole 212, and the third through-hole 211 penetrates the second stamping stand 21 in parallel to the first direction F1.
[0042] The second stamping stand 21 has bosses 213 on both sides facing each other in the second direction F2, and a recess 214 is formed between the two bosses 213 on the second stamping stand 21. The recess 214 has two bottom bumps 215 and side bumps 216. The bottom bumps 215 are located on opposite outer sides of the riveting stand 22, and the side bumps 216 are located on one outer side of the riveting stand 22.
[0043] The riveting stand 22 is installed in the recess 214 of the second stamping stand 21. The riveting stand 22 has a fourth through-hole 221. The fourth through-hole 221 penetrates the riveting stand 22 parallel to the first direction F1.
[0044] As shown in FIG. 1, the top of the riveting stand 22 protrudes from the recess 214, and the top of the riveting stand 22 is approximately the same height as the top of the bump 215, so that the second object 92 can be stably placed on the top of the riveting stand 22, and the side of the second object 92 abuts one side of the side bump 216.
[0045] The projection range of the third through hole 211 falls within the projection range of the fourth through hole 221 , and the projection range of the fourth through hole 221 is equal to or greater than the projection range of the third through hole 211 .
[0046] The projection range of the first through portion 1611 and the second through portion 1661 includes the projection range of the third through portion 211, and the projection range of the first through portion 1611 and the second through portion 1661 is larger than the projection range of the third through portion 211.
[0047] The axial length of the guide holes 212 is parallel to the first direction F1. When each guide post 15 moves parallel to the first direction F1, it can enter or exit the corresponding guide hole 212 and move parallel to the first direction F1 within the guide hole 212.
[0048] The projection range of the unload plate 13 includes the projection range of the second balance weight 23 .
[0049] The operation principle of stamping and riveting the first object 91 and the second object 92 of the present invention will be described with reference to FIGS.
[0050] Referring to FIG. 4, a first object 91 is fed into the feeder 16 and a second object 92 is placed on top of the riveting stand 22 .
[0051] At this time, the steel ball 165 is in the open position, and the elastic force of the elastic member 163 pushes the first swing arm 1621 outward, and the second swing arm 1622 drives the first end 1641 of the positioning member 164 to enter the first through-hole 1611, and the first end 1641 of the positioning member 164 supports the first object 91 in a floating state.
[0052] As mentioned above, the shapes of the first object 91 and the second object 92 can be determined according to actual needs and can be any mutually rivetable die stamping parts, and are not limited to the illustrated first object 91 being a nut and the second object 92 being a plate.
[0053] When both the first object 91 and the second object 92 are positioned, the first stamping member 10 can be controlled to descend, i.e., move towards the second stamping member 20 parallel to the first direction F1.
[0054] The means for controlling the operation of the first stamping member 10 can be, for example, a servo system, but is not limited thereto and can be designed according to actual needs.
[0055] 5, the first stamping stand 11 simultaneously lowers the stamping head 12, unload plate 13, movable member 14, guide posts 15, and supply device 16. When the unload plate 13 is pressed down onto the boss 213 of the second stamping stand 21, each guide post 15 is inserted into the corresponding guide hole 212, and the protrusion 1662 at the bottom of the supply stand 166 comes into contact with the second object 92.
[0056] At this time, the unloading plate 13, the movable member 14 and the supply device 16 cannot continue to move downward, and the first stamping stand 11, the stamping head 12 and the guide column 15 can still continue to move downward, but the stamping head 12 does not pass through the steel ball 165.
[0057] 6, the first stamping stand 11, the stamping head 12 and the guide column 15 continue to move downward. When the stamping head 12 passes the steel balls 165, it pushes the steel balls 165 outward, which causes the second swing arm 1622 to swing, causing the first end 1641 of the positioning member 164 to exit the first through-hole 1611, and the first swing arm 1621 to compress the elastic member 163.
[0058] As the positioning member 164 that originally supported the first object 91 has withdrawn from the first penetration portion 1611, the first object 91 passes from the first penetration portion 1611 into the second penetration portion 1661 and then onto the top of the second object 92; at this time, the first object 91 and the second object 92 are merely in contact with each other and are not riveted to each other.
[0059] When the first object 91 enters the second penetration 1661 and the first detection member 167 detects the first object 91, the first detection member 167 sends a signal to the servo system to control the first stamping stand 11, the stamping head 12 and the guide column 15 to continue moving downward. Conversely, if the first detection member 167 does not detect the first object 91, it sends a signal to the servo system to control the first stamping stand 11, the stamping head 12 and the guide column 15 to stop moving downward, and the operator performs an inspection.
[0060] Referring to FIG. 7, the first stamping stand 11 continues to move downwards, driving the stamping head 12, which stamps and rivets the first object 91 into the second object 92 to form a finished product.
[0061] When the first object 91 is pressed into the second object 92, the first object 91 shears the material at the corresponding position of the second object 92, embedding the first object 91 into the second object 92, and the sheared material 921 sheared at the corresponding position of the second object 92 is discharged outside the second stamping stand 21 through the fourth through-hole 221 of the riveting stand 22 and the third through-hole of the second stamping stand 21.
[0062] Next, the servo system controls the first stamping member 10 to rise parallel to the first direction F1 and return to the state shown in Figure 4, and then places new first objects 91 and second objects 92 to perform the stamping and riveting process of the next set of finished products.
[0063] For the structure in which the first object 91 and the second object 92 are stamped and riveted together, reference can be made to the enlarged structural views of Figures 8 and 9. Figure 8 shows that the first object 91 and the second object 92 have not yet been stamped and riveted together. Figure 9 shows the situation in which the first object 91 and the second object 92 have been stamped and riveted together, generating shear material 921.
[0064] 4 to 7, based on the above description of the stamping and riveting process, the size design of the first penetration portion 1611 and the second penetration portion 1661 is based on the principle that they can pass through the first object 91. The size design of the third penetration portion 211 and the fourth penetration portion 221 is based on the principle that they can pass through the shear material 921.
[0065] The shapes of the first through-hole 1611 , the second through-hole 1661 , the third through-hole 211 and the fourth through-hole 221 can be designed according to the actual shapes of the first object 91 and the shear material 921 .
[0066] For example, if the first object 91 is a hexagonal nut, the cross-sections of the first through-hole 1611 and the second through-hole 1661 may be hexagonal or circular, or may be of another shape that allows the first object 91 to move smoothly within the first through-hole 1611 and the second through-hole 1661 parallel to the first direction F1.
[0067] Similarly, the shapes of the third penetration portion 211 and the fourth penetration portion 221 may be set to match the shape of the shear material 921, or may be other shapes that allow the shear material 921 to move smoothly within the third penetration portion 211 and the fourth penetration portion 221 parallel to the first direction F1.
[0068] Referring to Figures 4 and 10, the first object 91 and the second object 92 can be positioned by a motor or manually.
[0069] For example, in Fig. 10, a first object 91 is blown into a specified position, i.e., into the supply device 16 shown in Fig. 4, by a combination of air pressure parameters and mechanisms. A second object 92 is a long plate that is continuously supplied to the machine.
[0070] The first detection member 167 detects whether or not the first object 91 is lowered, and the second detection member 168 detects whether or not the first object 91A is positioned.
[0071] 10, a first object 91 located below is stamped and riveted to a second object 92, and another first object 91A above is positioned, and when the second object 92 onto which the first object 91 has been stamped and riveted is removed, the first object 91 descends onto the upper surface of the second object 92 to perform the next stamping and riveting process. After the first object 91A, the other first objects 91B to 91E, etc., perform the subsequent stamping and riveting process.
[0072] In summary, the stamping and riveting mechanism provided by the present invention does not require the use of additional riveting equipment, and can ideally mate the first and second objects by stamping and rive them together, making the process simple, fast, and of stable quality, thereby reducing production costs.
[0073] Although the present invention discloses the embodiments as described above, the present invention is not limited to the above, and those skilled in the art can make changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention is determined by the scope of the utility model registration claims described below. [Explanation of symbols]
