[0048] In the present embodiment, since the material belt 700 is movably arranged between the upper clamping die seat 100 and the lower clamping die seat 200, the conveying of the material belt 700 ensures that the raw materials are finally formed into a large-sized stamping workpiece under the gradual clamping of the upper clamping die seat 100 and the lower clamping die seat 200. The fixing groove 310 provided on the mounting support 300 provides an installation position for the fixed limit seat 430. Since the fixed limit seat 430 is at least partially embedded in the fixing groove 310, it is ensured that the fixed limit seat 430 is prevented from shifting when the hook component 410 swings or hooks out the large-sized stamping workpiece, thereby ensuring the reliability of the installation of the fixed limit seat 430.

[0049] It can be understood that the fool-proofing method of the fool-proofing progressive die for large-sized stamping workpieces disclosed in the present invention, with the cooperation of the upper pressure clamping die seat 100 and the lower pressure clamping die seat 200, gradually completes the stamping of the raw materials to form a large-sized stamping workpiece. Since a waiting area is provided on the large-sized stamping workpiece, when the large-sized stamping workpiece needs to be separated from the material belt 700, the upper pressure clamping die seat 100 moves downward, and the material belt 700 conveys the large-sized stamping workpiece with forward inertia, so that the hook end of the hook component 410 slides along the outer surface of the large-sized stamping workpiece under the push of the forward inertia of the large-sized stamping workpiece. The predetermined sliding trajectory gradually swings up to the preset limit Position 22, after passing the preset limit position 22, since there is no large-sized stamping workpiece to resist, the hook end of the hook component 410 automatically swings down under the action of its own weight and connects with the waiting area for the large-sized stamping workpiece, ensuring that when the upper pressure clamping seat 100 moves upward, the large-sized stamping workpiece can be hooked up and dropped into the finished product area, and the above operation is repeated to avoid the large-sized stamping workpiece from sticking to the material strip 700, the next large-sized stamping workpiece, the upper pressure clamping seat 100 and the lower pressure clamping seat 200 before falling into the finished product area, thereby ensuring the stamping efficiency of the large-sized stamping workpiece fool-proof progressive die 10.

[0050] It can also be understood that the fool-proofing method of the fool-proofing progressive die for large-sized stamping workpieces disclosed in the present invention uses the hook component 410 of the fool-proofing assembly 400 to hook the large-sized stamping workpiece into the finished product area. The hook component 410 has a simple structure and improves the efficiency of the large-sized stamping workpiece falling into the finished product area, thereby improving the stamping efficiency of the fool-proofing progressive die 10 for large-sized stamping workpieces.

[0051] For further information, please also refer to Figures 1 to 9 In one embodiment, a foolproof method for a foolproof progressive die for a large-size stamping workpiece comprises the following steps:

[0052] S110, controlling the material belt 700 to convey the required raw materials; it can be understood that the material belt 700 gradually conveys the raw materials to the corresponding stamping positions.

[0053] S120, controlling the upper clamping die seat 100 to gradually stamp the raw material in the direction of the lower clamping die seat 200; it can be understood that the coordinated clamping action of the upper clamping die seat 100 and the lower clamping die seat 200 enables the raw material to be formed after stamping at various positions.

[0054] S130, after the stamping is completed, the cutting blade is controlled to cut, and a first large-sized stamping workpiece 20 is separated from the material strip 700, wherein a first hanging area 21 is provided on the first large-sized stamping workpiece 20; it can be understood that after the first stamping is completed, the first large-sized stamping workpiece 20 needs to be cut from the raw material to ensure that the first large-sized stamping workpiece 20 can be separated from the raw material so that it can fall into the finished product area later.

[0055] It can also be understood that after the stamping is completed, the first large-size stamping workpiece 20 is placed in the shape of an arch bridge on the material belt 700 for transmission. Specifically, the first large-size stamping workpiece 20 includes a first placement plate 23, a middle connecting plate 24 and a second placement plate 25 connected in sequence, one end of the first placement plate 23 and one end of the second placement plate 25 are respectively obliquely connected to the two ends of the middle connecting plate 24, and the other end of the first placement plate 23 and the other end of the second placement plate 25 are both placed on the material belt 700 to keep the middle connecting plate 24 away from the material belt 700, wherein the other end of the first placement plate 23 is provided with a first hanging area 21, and the other end of the second placement plate 25 is arranged close to the finished product area.

[0056] S140, continue to control the material belt 700 to move forward so that the hook component 410 is located above the first large-sized stamping workpiece 20; it can be understood that since the hook component 410 is located above the first large-sized stamping workpiece 20, it is ensured that the subsequent hook component 410 can slide along the outer surface of the first large-sized stamping workpiece 20 along the predetermined sliding trajectory and gradually swing upward.

[0057] It should be noted that sliding along the outer surface of the first large-size stamping workpiece 20 means sliding along the side of the first placement plate 23 facing away from the material strip 700 .

[0058] S150, continue to control the upper pressure clamping seat 100 to move downward; it can be understood that the upper pressure clamping seat 100 continues to move downward to ensure that the hook component 410 can gradually swing upward according to the predetermined sliding trajectory.

[0059] S160, based on the forward inertia of the material belt 700 conveying the first large-size stamping workpiece 20, the hooking end of the hook component 410 is pushed up along the predetermined sliding track to the preset limit position 22, and after passing the preset limit position 22, as shown in FIG. Figure 8 and Fig. 9 As shown, the hook component 410 swings down under the action of its own weight and connects with the first waiting area 21, and continues to control the upper pressure clamping seat 100 to move upward; it can be understood that since the material belt 700 conveys the first large-sized stamping workpiece 20 with forward inertia, the hook end of the hook component 410 slides along the outer surface of the first large-sized stamping workpiece 20 along a predetermined sliding trajectory under the push of the forward inertia of the first large-sized stamping workpiece 20, and gradually swings up to the preset limit position 22. After passing the preset limit position 22, since there is no resistance from the first large-sized stamping workpiece 20, the hook end of the hook component 410 automatically swings down under the action of its own weight and connects with the first waiting area 21. Since the upper pressure clamping seat 100 continues to be controlled to move upward, the first large-sized stamping workpiece 20 is hooked up by the upper pressure clamping seat 100.

[0060] Furthermore, if Figures 7 to 9 As shown, the preset limit position 22 is adjacent to the first waiting hanging area 21, and in the conveying direction of the material belt 700, the first waiting hanging area 21 and the preset limit position 22 are sequentially distributed on the other end of the first placement plate 23. Specifically, the preset limit position 22 is the edge of the first waiting hanging area 21.

[0061] S170, the first large-sized stamping workpiece 20 falls into the finished product area, the material belt 700 is continued to be controlled to move forward, the upper pressure clamping seat 100 and the lower pressure clamping seat 200 are controlled to continue stamping, and the second large-sized stamping workpiece is separated, and steps S130-S170 are repeated.

[0062] It can be understood that the large-size stamping workpiece fool-proof progressive die 10 adopts continuous and rapid stamping to ensure that the large-size stamping workpieces can be stamped in sequence, and prevent the large-size stamping workpieces from sticking to the material strip 700, the next large-size stamping workpiece, the upper pressing die seat 100 and the lower pressing die seat 200 before falling into the finished product area, thereby ensuring the stamping efficiency of the large-size stamping workpiece fool-proof progressive die 10.

[0063] It should be noted that the large-size stamped workpiece, the first large-size stamped workpiece 20 and the second large-size stamped workpiece refer to formed workpieces after the upper pressure clamping seat 100 and the lower pressure clamping seat 200 are gradually stamped.

[0064] It should also be noted that the direction in which the material belt 700 conveys the large-sized stamping workpiece moves along the position where the fool-proofing component 400 is set.

[0065] Furthermore, if Figure 4 and Figure 5 As shown, in one embodiment, the large-size stamping workpiece fool-proof progressive die 10 further includes a reinforcing snap-fit ​​block 600, which is disposed between the upper pressing die seat 100 and the mounting support 300, and the reinforcing snap-fit ​​block 600 is fixedly connected to the upper pressing die seat 100, and a snap-fit ​​groove 610 is formed at one end of the reinforcing snap-fit ​​block 600 facing the fixed stop seat 430, and the fixed stop seat 430 is at least partially accommodated in the snap-fit ​​groove 610. In this embodiment, since the fixed stop seat 430 is at least partially accommodated in the snap-fit ​​groove 610, and the fixed stop seat 430 is at least partially embedded in the fixed groove 310, the firmness of the installation position of the fixed stop seat 430 is further enhanced, thereby ensuring the reliability of the installation of the hook component 410.

[0066] like Figure 2 , Figure 5 and Figure 7 As shown, in one embodiment, the hook component 410 includes a hook body 411 and a hook bent block 412 connected to each other, the hook body 411 is formed with a swing hole 411a, the hanging pin 420 is passed through the swing hole 411a, and the hook bent block 412 is arranged in the direction of conveying the material belt 700, and is used to connect with the area to be hung to hook out large-sized stamping workpieces. In this embodiment, since the hook body 411 is formed with a swing hole 411a, the swing hole 411a cooperates with the hanging pin 420, so that the hook body 411 swings up and down around the hanging pin 420, and the hook-out bent block 412 has a certain bending degree, and the hook-out bent block 412 is set in the direction of conveying the material belt 700, ensuring that the hook-out bent block 412 can be connected to the waiting area of ​​the large-sized stamping workpiece, ensuring the reliability of the hook-out bent block 412 hooking the large-sized stamping workpiece into the finished product area, thereby avoiding the situation where the large-sized stamping workpiece is adhered to the material belt 700, the next large-sized stamping workpiece, the upper pressure clamping seat 100 and the lower pressure clamping seat 200 before falling into the finished product area.

[0067] Furthermore, if Figures 5 to 7As shown, in one embodiment, the anti-foolproof component 400 also includes an elastic reset member 440, one end of the elastic reset member 440 is connected to the hook body 411, and the other end of the elastic reset member 440 is connected to the inner wall of the first stroke groove 320, which is used to automatically reset the hook bent block 412 and connect to the waiting area when the hook body 411 swings down. It can be understood that when the hook body 411 does not swing, the elastic reset member 440 is in the original state, that is, the elastic reset member 440 does not undergo elastic deformation. When the hook body 411 swings up to the preset limit position 22 along the predetermined sliding track, the elastic reset member 440 elastically stretches. After passing the preset limit position 22, under the combined action of the self-gravity of the hook body 411 and the elastic return force of the elastic reset member 440, the hook body 411 can swing down in time, and the hook-out bent block 412 can be clamped in the waiting area of ​​the large-sized stamping workpiece, so that the large-sized stamping workpiece can fall into the finished product area in time. The additional elastic reset member 440 can more effectively improve the reliability of the connection between the hook-out bent block 412 and the waiting area of ​​the large-sized stamping workpiece. In this embodiment, the elastic reset member 440 is a tension spring, which produces elastic deformation, that is, elastic stretching, when subjected to axial tension. When the external force is removed, the tension spring automatically shortens and resets.

[0068] Please also read Figures 6 to 8 In one of the embodiments, a first smooth transition portion 412a is formed on the side of the hook-out bend block 412 that contacts the large-sized stamping workpiece. The additional first smooth transition portion 412a ensures that the hook-out bend block 412 is in direct contact with the outer surface of the large-sized stamping workpiece. On the one hand, it prevents the outer surface of the large-sized stamping workpiece from being worn and affecting the forming effect of the large-sized stamping workpiece. On the other hand, it prevents the hook-out bend block 412 from getting stuck on the outer surface of the large-sized stamping workpiece when it gradually swings down, thereby affecting the overall stamping efficiency. In this embodiment, the hook-out bend block 412 is made of metal. Furthermore, in one of the embodiments, the first smooth transition portion 412a is subjected to surface heat treatment to ensure that the first smooth transition portion 412a is not easily stuck when contacting the outer surface of the large-sized stamping workpiece and reduces the wear of the large-sized stamping workpiece.

[0069] like Figures 6 to 9 As shown, in one embodiment, a second smooth transition portion 412b is formed at the connection between the side wall of the hook body 411 and the side wall of the hook-out curved block 412, and the second smooth transition portion 412b is clamped in the waiting hanging area. In this embodiment, since the connection between the side wall of the hook body 411 and the side wall of the hook-out curved block 412 is clamped in the waiting hanging area, the additional second smooth transition portion 412b avoids wearing the edge of the large-sized stamping workpiece, thereby improving the forming effect of the large-sized stamping workpiece.

[0070] Furthermore, in one of the embodiments, the fool-proofing component 400 also includes an elastic telescopic slider (not shown), and the first smooth transition portion 412a is formed with an installation avoidance hole (not shown), and the elastic telescopic slider is at least partially accommodated in the installation avoidance hole, so that the elastic telescopic slider elastically contracts when abutting against the outer surface of the large-sized stamping workpiece, and automatically elastically extends and resets when leaving the outer surface of the large-sized stamping workpiece, while ensuring the firmness of the elastic telescopic slider clamped in the hanging area of ​​the large-sized stamping workpiece.

[0071] In one embodiment, the hook body 411 and the hook-out curved block 412 are integrally formed. It is understood that the hook body 411 and the hook-out curved block 412 need to cooperate with hooking the large-sized stamping workpiece into the finished product area. Since the large-sized stamping workpiece has a high weight, the structural strength of the hook body 411 and the hook-out curved block 412 is required to be high to ensure the firmness of the connection between the hook body 411 and the hook-out curved block 412, and to avoid the hook-out curved block 412 from breaking when hooking the large-sized stamping workpiece. In this embodiment, the hook body 411 and the hook-out curved block 412 are integrally die-cast to provide higher strength.

[0072] For further information, please also refer to Figures 5 to 7 In one embodiment, the foolproof assembly 400 further includes a stopper 450, which is disposed on a side of the second travel groove 431 facing the hook-out curved block 412, and is used to stop the hook body 411 when the hook body 411 is swung down, so that the hook-out curved block 412 is engaged with the waiting area. In this embodiment, since the stopper 450 is disposed on a side of the second travel groove 431 facing the hook-out curved block 412, when the hook body 411 is swung down, on the one hand, the hook body 411 is prevented from directly colliding with the edge of the second travel groove 431, and on the other hand, the hook body 411 is prevented from excessively swinging down, which affects the reliability of the hook-out curved block 412 being engaged with the waiting area of ​​the large-sized stamping workpiece.

[0073] Furthermore, if Figure 5 As shown, in one embodiment, the large-size stamping workpiece fool-proof progressive die 10 further includes an anti-collision damping sheet 500, which is disposed on the stop block 450 to prevent the hook body 411 from directly colliding with the stop block 450 when the hook body 411 is swung down. In this embodiment, the additional anti-collision damping sheet 500 prevents the hook body 411 from directly colliding with the stop block 450 when the hook body 411 is swung down, avoids contact wear between the hook body 411 and the stop block 450, and has a certain buffering and shock absorbing effect.

[0074] like Figure 5As shown, in one embodiment, the lateral width of the first stroke groove 320 is greater than the lateral width of the second stroke groove 431. In this embodiment, since the lateral width of the first stroke groove 320 is greater than the lateral width of the second stroke groove 431, when the hook body 411 swings upward along the predetermined sliding track, the hook body 411 first touches the lower edge of the second stroke groove 431, and then touches the lower edge of the first stroke groove 320. Further, in one embodiment, the lower edge of the first stroke groove 320 is formed with a first preset fillet 321, and the lower edge of the second stroke groove 431 is formed with a second preset fillet 431a. In this embodiment, the additional first preset fillet 321 and the second preset fillet 431a avoid wear when the hook body 411 collides with the lower edge of the first stroke groove 320 and the lower edge of the second stroke groove 431, and at the same time improves the service life of the fixed limit seat 430 and the mounting support 300.

[0075] like Figure 2 , Figure 6 and Fig.10 As shown, in one embodiment, the number of foolproofing components 400 is two, and both foolproofing components 400 are arranged on the mounting support 300 to jointly hook out the large-sized stamping workpiece. In this embodiment, both foolproofing components 400 are installed on the support 300, so that the two hook components 410 can hook the waiting area of ​​the large-sized stamping workpiece at the same time, ensuring that the force of hooking up the large-sized stamping workpiece is relatively uniform, improving the efficiency of hooking out the large-sized stamping workpiece, thereby improving the stamping efficiency of the foolproofing progressive die 10 for large-sized stamping workpieces.

[0076] Compared with the prior art, the present invention has at least the following advantages:

[0077] 1) The foolproof method for foolproof progressive die of large-sized stamping workpiece disclosed in the present invention is to gradually complete the stamping of raw materials to form a large-sized stamping workpiece under the cooperation of the upper pressing die holder 100 and the lower pressing die holder 200. Since the large-sized stamping workpiece is provided with a waiting area, when the large-sized stamping workpiece needs to be separated from the material belt 700, the upper pressing die holder 100 moves downward, and the material belt 700 conveys the large-sized stamping workpiece with forward inertia, so that the hook end of the hook component 410 slides along the outer surface of the large-sized stamping workpiece under the push of the forward inertia of the large-sized stamping workpiece, and gradually swings up to the preset limit position. After passing the preset limit position 22, since there is no large-sized stamping workpiece to resist, the hook end of the hook component 410 automatically swings down under the action of its own weight and connects with the waiting area for the large-sized stamping workpiece, ensuring that when the upper pressure clamping seat 100 moves upward, the large-sized stamping workpiece can be hooked up and dropped into the finished product area, and the above operation is repeated to avoid the large-sized stamping workpiece from sticking to the material strip 700, the next large-sized stamping workpiece, the upper pressure clamping seat 100 and the lower pressure clamping seat 200 before falling into the finished product area, thereby ensuring the stamping efficiency of the large-sized stamping workpiece fool-proof progressive die 10.

[0078] 2) The fool-proofing method for the fool-proofing progressive die for large-sized stamping workpieces disclosed in the present invention uses the hook component 410 of the fool-proofing assembly 400 to hook the large-sized stamping workpiece into the finished product area. The hook component 410 has a simple structure and improves the efficiency of the large-sized stamping workpiece falling into the finished product area, thereby improving the stamping efficiency of the fool-proofing progressive die 10 for large-sized stamping workpieces.

[0079] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be subject to the attached claims.
