AI Technical Summary
Large stamped workpieces are prone to sticking to the strip, the next workpiece, or the die body during progressive die stamping production, which affects stamping efficiency.
The hook component, which employs a foolproof design, is propelled by the forward inertia of a large-sized stamped workpiece through its hook-out end, and then swings along a predetermined sliding trajectory to a preset limit position. Under its own weight, it swings down and connects with the hanging area, ensuring that the workpiece is hooked into the finished product area.
This prevents the workpiece from sticking to the strip, the next workpiece, or the die before it falls into the finished product area, thus improving stamping efficiency.

The upper pressing die holder and the lower pressing die holder are arranged correspondingly. The material belt is movably arranged between the upper pressing die holder and the lower pressing die holder, and is used to convey a large-size stamping workpiece and raw materials required by the large-size stamping workpiece. The mounting support is arranged on the upper pressing die holder, and the mounting support is formed with a fixed groove and a first stroke groove that are connected. The foolproof assembly includes a hook component, a hanging pin, and a fixed limiting seat. At least part of the fixed limiting seat is embedded in the fixed groove. The fixed limiting seat is formed with a second stroke groove. The first stroke groove, the fixed groove, and the second stroke groove are sequentially connected. The two ends of the hanging pin are fixedly connected to two opposite inner walls of the second stroke groove. The hook component is sequentially arranged in the first stroke groove, the fixed groove, and the second stroke groove. The connecting end of the hook component is swingably arranged on the hanging pin. The hooking end of the hook component is used to connect with a to-be-hung area of the large-size stamping workpiece.

After passing through the preset limit position, the hooking end swings downward to connect with the to-be-hung area. When the upper pressing die holder moves upward, the large-size stamping workpiece is hooked into a finished product area.
[0045] The foolproof method of the large-size stamping workpiece foolproof progressive die described above gradually forms a large-size stamping workpiece by stamping the raw material under the cooperation of the upper and lower pressing die bases. Since the large-size stamping workpiece is provided with a hanging area, when the large-size stamping workpiece needs to be separated from the material belt, the upper pressing die base descends, the material belt has forward inertia when conveying the large-size stamping workpiece, the hooking end of the hook component gradually swings up to the preset limit position along the predetermined sliding track on the outer surface of the large-size stamping workpiece under the forward inertia of the large-size stamping workpiece, and after passing through the preset limit position, the hooking end of the hook component automatically swings down to connect with the hanging area of the large-size stamping workpiece under the action of gravity since there is no resistance of the large-size stamping workpiece, so that the large-size stamping workpiece can be hooked and dropped into the finished product area when the upper pressing die base ascends, and the above operation is repeated to avoid the situation that the large-size stamping workpiece is adhered to the material belt, the next large-size stamping workpiece, the upper pressing die base and the lower pressing die base before being dropped into the finished product area. The foolproof method of the large-size stamping workpiece foolproof progressive die of the present disclosure uses the hook component of the foolproof assembly to hook the large-size stamping workpiece into the finished product area, the hook component has a simple structure, improves the efficiency of the large-size stamping workpiece dropped into the finished product area, and thus improves the stamping efficiency of the large-size stamping workpiece foolproof progressive die.
[0046] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:
[0047] Please refer to Figures 1 to 10The foolproof method of the large-size stamping workpiece foolproof progressive die in an embodiment is executed by using the large-size stamping workpiece foolproof progressive die 10, wherein the large-size stamping workpiece foolproof progressive die 10 comprises an upper pressing die holder 100, a lower pressing die holder 200, a material belt 700, a mounting support 300 and at least one foolproof assembly 400. The upper pressing die holder 100 is arranged correspondingly with the lower pressing die holder 200. The material belt 700 is movably arranged between the upper pressing die holder 100 and the lower pressing die holder 200, and is used for conveying the large-size stamping workpiece and the raw material required by the large-size stamping workpiece. The mounting support 300 is arranged on the upper pressing die holder 100, and the mounting support 300 is formed with a fixed groove 310 and a first stroke groove 320 which are connected in sequence. The foolproof assembly 400 comprises a hook component 410, a hanging pin 420 and a fixed limiting seat 430. At least part of the fixed limiting seat 430 is embedded in the fixed groove 310. The fixed limiting seat 430 is formed with a second stroke groove 431. The first stroke groove 320, the fixed groove 310 and the second stroke groove 431 are connected in sequence. The two ends of the hanging pin 420 are fixedly connected to the two opposite inner side walls of the second stroke groove 431 in sequence. The hook component 410 is sequentially arranged in the first stroke groove 320, the fixed groove 310 and the second stroke groove 431. The connecting end of the hook component 410 is swingably sleeved on the hanging pin 420. The hooking end of the hook component 410 is used for connecting with the to-be-hung area of the large-size stamping workpiece. When the upper pressing die holder 100 moves downward, the hooking end swings upward along a predetermined sliding track to a preset limit position 22. After passing through the preset limit position 22, the hooking end swings downward to connect with the to-be-hung area. When the upper pressing die holder 100 moves upward, the large-size stamping workpiece is hooked into the finished product area.
[0048] In the embodiment, since the material belt 700 is movably arranged between the upper pressing die holder 100 and the lower pressing die holder 200, the feeding of the material belt 700 ensures that the raw material is finally formed into a large-size stamping workpiece under the step-by-step pressing of the upper pressing die holder 100 and the lower pressing die holder 200. The fixing groove 310 provided on the mounting support 300 provides a mounting position for the fixed limiting seat 430. Since the fixed limiting seat 430 is at least partially embedded in the fixing groove 310, the displacement of the fixed limiting seat 430 is prevented when the hook component 410 swings or hooks the large-size stamping workpiece, thereby ensuring the mounting stability of the fixed limiting seat 430. Since the mounting support 300 is formed with the interconnected fixing groove 310 and first stroke groove 320, the fixed limiting seat 430 is formed with the second stroke groove 431, and the first stroke groove 320, the fixing groove 310 and the second stroke groove 431 are sequentially connected, the hook component 410 can sequentially pass through the first stroke groove 320, the fixing groove 310 and the second stroke groove 431, which ensures that the hook component 410 can swing and be mounted on the hanging pin 420 of the second stroke groove 431, and provides sufficient swing space for the hook component 410 in the first stroke groove 320, the fixing groove 310 and the second stroke groove 431, thereby ensuring the swing stroke reliability of the hook component 410 when hooking the large-size stamping workpiece, and improving the stamping efficiency of the large-size stamping workpiece.
[0049] It can be understood that the fool-proof method of the large-size stamping workpiece fool-proof progressive die of the present disclosure forms a large-size stamping workpiece by step-by-step stamping of a raw material under the cooperation of the upper pressing die holder 100 and the lower pressing die holder 200. When the large-size stamping workpiece needs to be separated from the material belt 700, the upper pressing die holder 100 descends, and the material belt 700 feeds the large-size stamping workpiece with forward inertia, so that the hooking end of the hook component 410 gradually swings upward along the predetermined sliding track on the outer surface of the large-size stamping workpiece to the preset limit position 22 under the forward inertia of the large-size stamping workpiece. After passing through the preset limit position 22, the hooking end of the hook component 410 is automatically swung downward to connect with the hanging area of the large-size stamping workpiece under the action of gravity, which ensures that the large-size stamping workpiece can be hooked and dropped into the finished product area when the upper pressing die holder 100 ascends. The above operation is repeated to avoid the situation that the large-size stamping workpiece is adhered to the material belt 700, the next large-size stamping workpiece, the upper pressing die holder 100 and the lower pressing die holder 200 before falling into the finished product area, thereby ensuring the stamping efficiency of the large-size stamping workpiece fool-proof progressive die 10.
[0050] It can also be understood that the fool-proof method of the large-size stamping workpiece fool-proof progressive die of the present disclosure uses the hook component 410 of the fool-proof assembly 400 to complete the hooking of the large-size stamping workpiece into the finished product area. The hook component 410 is simple in structure and improves the efficiency of the large-size stamping workpiece falling into the finished product area, thereby improving the stamping efficiency of the large-size stamping workpiece fool-proof progressive die 10.
[0051] Further, please refer to Figures 1 to 9 In one embodiment, the fool-proof method of the large-size stamping workpiece fool-proof progressive die includes the following steps:
[0052] S110, control the material belt 700 to convey the required raw material; it can be understood that the material belt 700 gradually conveys the raw material to the corresponding stamping position.
[0053] S120, control the upper compression die holder 100 to gradually stamp the raw material in the direction towards the lower compression die holder 200; it can be understood that the combined die action of the upper compression die holder 100 and the lower compression die holder 200 enables the raw material to be formed after stamping at each position.
[0054] S130, after stamping, control the cutting blade to cut and separate the first large-size stamping workpiece 20 from the material belt 700, wherein the first large-size stamping workpiece 20 is provided with a first hanging area 21; it can be understood that after the first stamping is completed, the first large-size stamping workpiece 20 needs to be cut from the raw material to ensure that the first large-size stamping workpiece 20 can be separated from the raw material for subsequent falling into the finished product area.
[0055] It can also be understood that after stamping, the first large-size stamping workpiece 20 is placed in an arch bridge shape 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 inclinedly connected to both 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, so that the middle connecting plate 24 is away from the material belt 700. Among them, the other end of the first placement plate 23 is provided with the first hanging area 21, and the other end of the second placement plate 25 is close to the finished product area.
[0056] S140, continue to control the material belt 700 to advance so that the hook component 410 is located above the first large-size stamping workpiece 20; it can be understood that since the hook component 410 is located above the first large-size stamping workpiece 20, it is ensured that the subsequent hook component 410 can slide along the outer surface of the first large-size stamping workpiece 20 to gradually swing upward along a predetermined sliding track.
[0057] It should be noted that the sliding along the outer surface of the first large-size stamping workpiece 20 is the sliding along the side of the first placement plate 23 away from the material belt 700.
[0058] S150, continue to control the upper compression die holder 100 to descend; it can be understood that the upper compression die holder 100 continues to descend, which ensures that the hook component 410 can gradually swing up according to the predetermined sliding track.
[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 to swing up along the predetermined sliding track to the preset limit position 22, and after passing through the preset limit position 22, as shown in Figure 8 and Figure 9 , the hook component 410 swings down under the action of gravity and is connected with the first hanging area 21, and the upper compression die holder 100 continues to ascend; it can be understood that, due to the forward inertia of the material belt 700 conveying the first large-size stamping workpiece 20, the hooking end of the hook component 410 gradually swings up along the outer surface of the first large-size stamping workpiece 20 to the preset limit position 22 under the pushing of the forward inertia of the first large-size stamping workpiece 20, and after passing through the preset limit position 22, the hooking end of the hook component 410 swings down under the action of gravity and is connected with the first hanging area 21 due to the absence of resistance from the first large-size stamping workpiece 20, and the first large-size stamping workpiece 20 is hooked by the upper compression die holder 100 due to the continuous control of the upper compression die holder 100 to ascend.
[0060] Further, as shown in Figures 7 to 9 , the preset limit position 22 is adjacent to the first hanging area 21, and in the conveying direction of the material belt 700, the first 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 hanging area 21.
[0061] S170, the first large-size stamping workpiece 20 falls into the finished product area, the material belt 700 continues to advance, the upper compression die holder 100 and the lower compression die holder 200 continue to stamp, and the second large-size stamping workpiece is separated to repeat steps S130-S170.
[0062] It can be understood that the large-size stamping workpiece fool-proof progressive die 10 adopts continuous rapid stamping, which ensures that the large-size stamping workpiece can be stamped in sequence and prevents the large-size stamping workpiece from being adhered to the material belt 700, the next large-size stamping workpiece, the upper compression die holder 100 and the lower compression die holder 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 stamping workpiece, the first large-size stamping workpiece 20 and the second large-size stamping workpiece refer to the formed workpiece after the upper pressing die holder 100 and the lower pressing die holder 200 are stepwise stamped.
[0064] It should be further noted that the direction in which the material belt 700 conveys the large-size stamping workpiece moves along the position where the fool-proof assembly 400 is arranged.
[0065] Further, as shown in Figure 4 and Figure 5 , in one embodiment, the large-size stamping workpiece fool-proof progressive die 10 further comprises a reinforcing clamping block 600, which is arranged between the upper pressing die holder 100 and the mounting support 300, and is fixedly connected to the upper pressing die holder 100. The reinforcing clamping block 600 is formed with a clamping groove 610 towards one end of the fixed limiting seat 430, and the fixed limiting seat 430 is at least partially accommodated in the clamping groove 610. In this embodiment, since the fixed limiting seat 430 is at least partially accommodated in the clamping groove 610 and at least partially embedded in the fixed groove 310, the firmness of the mounting position of the fixed limiting seat 430 is further enhanced, thereby ensuring the reliability of the installation of the hook component 410.
[0066] As shown in Figure 2 , Figure 5 and Figure 7 , in one embodiment, the hook component 410 comprises a hook main body 411 and a hooking bending block 412 connected thereto. The hook main body 411 is formed with a swing hole 411a, and the hanging pin 420 is arranged in the swing hole 411a. The hooking bending block 412 is arranged towards the conveying direction of the material belt 700, and is used to connect with the to-be-hung area to hook the large-size stamping workpiece. In this embodiment, since the hook main body 411 is formed with the swing hole 411a, which cooperates with the hanging pin 420 to enable the hook main body 411 to swing up and down around the hanging pin 420, and the hooking bending block 412 has a certain bending degree and is arranged towards the conveying direction of the material belt 700, it is ensured that the hooking bending block 412 can connect with the to-be-hung area of the large-size stamping workpiece, and the reliability of the hooking bending block 412 to hook the large-size stamping workpiece into the finished product area is ensured, thereby avoiding the situation that the large-size stamping workpiece is adhered to the material belt 700, the next large-size stamping workpiece, the upper pressing die holder 100 and the lower pressing die holder 200 before falling into the finished product area.
[0067] Further, as shown in Figures 5 to 7As shown, in one of the embodiments, the fool-proof assembly 400 further comprises 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 slot 320, for automatically resetting the hook-out bent block 412 to be connected to the hanging 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 elastically deform, when the hook body 411 swings up to the preset limit position 22 along the predetermined sliding track, the elastic reset member 440 elastically elongates, and after passing through the preset limit position 22, under the joint action of the gravity of the hook body 411 and the elastic return force of the elastic reset member 440, it is ensured that the hook body 411 can swing down in time, it is ensured that the hook-out bent block 412 is clamped to the hanging area of the large-size stamping workpiece, and it is realized that the large-size stamping workpiece can fall into the finished product area in time. The added elastic reset member 440 can more effectively improve the firmness of the connection between the hook-out bent block 412 and the hanging area of the large-size stamping workpiece. In this embodiment, the elastic reset member 440 is a tension spring, which elastically deforms, that is, elastically elongates, when subjected to an axial tension, and automatically shortens and resets when the external force is removed.
[0068] Please see Figures 6 to 8 In one of the embodiments, one side of the hook-out bent block 412 in contact with the large-size stamping workpiece is formed with a first smooth transition part 412a, and the added first smooth transition part 412a ensures that the hook-out bent block 412 directly contacts the outer surface of the large-size stamping workpiece, which on the one hand avoids the outer surface of the large-size stamping workpiece from being abraded, affecting the forming effect of the large-size stamping workpiece, and on the other hand prevents the hook-out bent block 412 from being stuck on the outer surface of the large-size stamping workpiece when it gradually swings down, thereby affecting the overall stamping efficiency. In this embodiment, the hook-out bent block 412 is made of metal. Further, in one of the embodiments, the first smooth transition part 412a is subjected to surface heat treatment to ensure that the first smooth transition part 412a is not easy to be stuck and reduces the abrasion of the large-size stamping workpiece when contacting the outer surface of the large-size stamping workpiece.
[0069] As Figures 6 to 9 shown, in one of the embodiments, the connection between the side wall of the hook body 411 and the side wall of the hook-out bent block 412 is formed with a second smooth transition part 412b, and the second smooth transition part 412b is clamped to the 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 bent block 412 is clamped to the hanging area, the added second smooth transition part 412b avoids abrading the edge of the large-size stamping workpiece, thereby improving the forming effect of the large-size stamping workpiece.
[0070] Further, in one of the embodiments, the fool-proof assembly 400 further comprises an elastic telescopic slider (not shown in the figure), the first smooth transition part 412a is formed with a mounting avoidance hole (not shown in the figure), and the elastic telescopic slider is at least partially accommodated in the mounting avoidance hole, so that the elastic telescopic slider is elastically contracted when abutting against the outer surface of the large-sized stamping workpiece and is automatically elastically lengthened and reset when leaving the outer surface of the large-sized stamping workpiece, while ensuring the firmness of the elastic telescopic slider clamped to the to-be-hung area of the large-sized stamping workpiece.
[0071] In one of the embodiments, the hook body 411 and the hook-out bending block 412 are integrally formed. It can be understood that the hook body 411 and the hook-out bending block 412 need to cooperate to hook the large-sized stamping workpiece into the finished product area. Since the large-sized stamping workpiece has a relatively high weight, the structural strength of the hook body 411 and the hook-out bending block 412 needs to be relatively high to ensure the firmness of the connection between the hook body 411 and the hook-out bending block 412 and to avoid the breakage of the hook-out bending block 412 when hooking the large-sized stamping workpiece. In the present embodiment, the hook body 411 and the hook-out bending block 412 are integrally pressure-cast formed to provide relatively high strength.
[0072] Further, please refer to Figures 5 to 7 In one of the embodiments, the fool-proof assembly 400 further comprises a resistance limiting block 450 arranged on the side of the second stroke groove 431 facing the hook-out bending block 412, for resisting the hook body 411 when it is lowered, so that the hook-out bending block 412 is clamped to the to-be-hung area. In the present embodiment, since the resistance limiting block 450 is arranged on the side of the second stroke groove 431 facing the hook-out bending block 412, when the hook body 411 is lowered, on the one hand, it avoids the direct collision of the hook body 411 with the edge of the second stroke groove 431, and on the other hand, it prevents the excessive lowering of the hook body 411, which affects the firmness of the clamping of the hook-out bending block 412 to the to-be-hung area of the large-sized stamping workpiece.
[0073] Further, as shown in Figure 5 In one of the embodiments, the large-sized stamping workpiece fool-proof progressive die 10 further comprises a collision-preventing shock-absorbing sheet 500 arranged on the resistance limiting block 450, for preventing the direct collision of the hook body 411 with the resistance limiting block 450 when it is lowered. In the present embodiment, the added collision-preventing shock-absorbing sheet 500 prevents the direct collision of the hook body 411 with the resistance limiting block 450 when it is lowered, avoids the contact wear between the hook body 411 and the resistance limiting block 450, and has a certain buffering and shock-absorbing effect.
[0074] As shown in Figure 5As shown, in one of the embodiments, the transverse width of the first stroke groove 320 is greater than the transverse width of the second stroke groove 431. In this embodiment, since the transverse width of the first stroke groove 320 is greater than the transverse width of the second stroke groove 431, when the hook body 411 swings along the predetermined sliding trajectory, 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 of the embodiments, the lower edge of the first stroke groove 320 is formed with a first preset round corner 321, and the lower edge of the second stroke groove 431 is formed with a second preset round corner 431a. In this embodiment, the first preset round corner 321 and the second preset round corner 431a are added to 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, the service life of the fixed limiting seat 430 and the mounting support 300 is improved.
[0075] As shown in Figure 2 , Figure 6 and Figure 10 , in one of the embodiments, the number of foolproof assemblies 400 is two, and both of the two foolproof assemblies 400 are arranged on the mounting support 300 to hook out large-sized stamping workpieces. In this embodiment, both of the two foolproof assemblies 400 are arranged on the mounting support 300, so that the two hook components 410 can simultaneously hook the hanging area of the large-sized stamping workpiece, ensure that the large-sized stamping workpiece is evenly stressed when being hooked, improve the efficiency of hooking out the large-sized stamping workpiece, and thus improve the stamping efficiency of the large-sized stamping workpiece foolproof progressive die 10.

[0077] 1) The fool-proof method of the large-size stamping workpiece fool-proof progressive die of the present disclosure, which gradually completes stamping of the raw material to form a large-size stamping workpiece under the cooperation of the upper and lower pressing die seats 100 and 200. The large-size stamping workpiece is provided with a hanging area. When the large-size stamping workpiece needs to be separated from the material belt 700, the upper pressing die seat 100 descends. The material belt 700 has forward inertia when conveying the large-size stamping workpiece. The hooking end of the hook component 410 gradually swings up to the preset limit position 22 along the predetermined sliding track on the outer surface of the large-size stamping workpiece under the pushing of the forward inertia of the large-size stamping workpiece. After passing through the preset limit position 22, the hooking end of the hook component 410 automatically swings down to connect with the hanging area of the large-size stamping workpiece under the action of gravity, because there is no resistance from the large-size stamping workpiece. When the upper pressing die seat 100 ascends, the large-size stamping workpiece can be hooked and dropped into the finished product area. The above operation is repeated to avoid the situation that the large-size stamping workpiece is stuck with the material belt 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.
[0078] 2) The fool-proof method of the large-size stamping workpiece fool-proof progressive die of the present disclosure, which uses the hook component 410 of the fool-proof assembly 400 to hook the large-size stamping workpiece into the finished product area. The hook component 410 is simple in structure and improves the efficiency of the large-size stamping workpiece falling into the finished product area, thereby improving the stamping efficiency of the large-size stamping workpiece fool-proof progressive die 10.
