Detailed Description of the Preferred Embodiments

[0026] Next, in combination with specific embodiments, the present application will be further described. It should be noted that, on the premise of non-conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0027] In the description of the present application, it should be noted that for orientation terms, such as terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation and position relationship are based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0029] The terms "comprising" and "having" in the description and claims of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0030] One preferred embodiment of the present application is, as Figures 1 to 8 shown, a stamping die with a detection tooling, including a die body 1, a feeding mechanism 2, and a detection mechanism 3. The feeding mechanism 2 is installed on both sides of the die body 1 and can clamp and convey a workpiece 4. The detection mechanism 3 is disposed on the feeding mechanism 2. The detection mechanism 3 can cooperate with the workpiece 4, and the feeding mechanism 2 can perform subsequent actions based on the position change after the cooperation of the workpiece 4 or the parameter change of the detection mechanism 3.

[0031] It should be known that traditional punching dies basically do not have an automated detection device, and manual detection is required after production. This phenomenon has led to a significant reduction in the qualified rate of the production of the workpiece 4, and it is time-consuming and laborious. At the same time, it may also be the reason for the punch to break. If it cannot be discovered in time, it may cause damage to the entire stamping die and may result in personal injury.

[0032] Therefore, in this embodiment, the problem is solved by designing a pinch mechanism 2 and a detection mechanism 3 on the stamping die. The stamping die realizes the automatic and high-efficiency detection of the workpiece 4 through the pinch mechanism 2 and the detection mechanism 3. Compared with the original manual detection, the detection efficiency is greatly improved, and the time consumed is short. At the same time, when a problem is detected in the workpiece 4, it can be promptly reflected to the staff, enabling timely loss prevention and avoiding the production of a large number of unqualified workpieces 4 and the damage of the stamping die.

[0033] In this embodiment, as Figure 2 , 4 shown, the detection mechanism 3 includes an inspection pin 30, and the inspection pin 30 is installed on the die body 1. A front hole 40 is provided on the workpiece 4, and the inspection pin 30 can cooperate with the front hole 40 to judge the opening state of the front hole 40 based on the cooperation state between the inspection pin 30 and the front hole 40.

[0034] It can be understood that after the workpiece 4 is punched by a traditional stamping die, it is directly sent to the next working process without detection. If the position where the workpiece 4 should be punched is not punched or the size of the hole is different from the requirement, the workpiece 4 with such problems is an unqualified product, and it is a complete waste of time and resources to proceed to the next process. Moreover, if the reason why the position where the workpiece 4 should be punched is not punched is that the punch of the stamping die is damaged, and the staff continues to work without knowing it, it may cause damage to the entire stamping die, and more seriously, it may cause harm to the staff. Therefore, a detection mechanism 3 is provided to remind the staff and improve the production qualification rate of the workpiece 4.

[0035] It should be known that the punching positions on the workpiece 4 are different. There is a front hole 40 and also a side hole 41. However, the detection methods for holes in different positions are quite different.

[0036] Therefore, in this embodiment, the detection mechanism 3 includes an inspection pin 30 for detecting the front hole 40, and there are multiple inspection pins 30 which are installed on the die body 1. The positions of the multiple inspection pins 30 correspond to the positions where the workpiece 4 should be punched, and the size of the inspection pin 30 is also the same as the size required for punching. After the workpiece 4 is punched, the pinch mechanism 2 will transfer the workpiece 4 to the position corresponding to the inspection pin 30, and drive the inspection pin 30 to cooperate with the front hole 40 on the workpiece 4 to judge whether the front hole 40 on the workpiece 4 is qualified. If the inspection pin 30 can pass through the front hole 40 normally, it means that all the front holes 40 on the workpiece 4 are qualified; if the inspection pin 30 does not pass through the front hole 40 and pushes the workpiece 4 away from the original position, it means that the workpiece 4 is unqualified in production.

[0037] It can be understood that if the inspection pin 30 does not pass through the front hole 40 but instead pushes the workpiece 4 away from its original position, the staff can promptly discover that there is a problem with the punching of this workpiece 4. At the same time, the punching die stops working, which can effectively avoid the occurrence of unqualified products in the subsequent large-scale production of workpieces 4 and can effectively prevent damage to the stamping die, further avoiding personal injuries to the staff. Therefore, the design of the detection mechanism 3 increases safety while improving efficiency.

[0038] In this embodiment, there are many positions on the workpiece 4 that need to be punched. As mentioned above, the workpiece 4 is provided with a front hole 40 and also a side hole 41. However, the inspection pin 30 is not suitable for inspecting the side hole 41 on the workpiece 4. If there is a problem with the side hole 41 such as missing punching or unqualified dimensions, the entire workpiece 4 is also unqualified.

[0039] So in this embodiment, as Figure 5 shown, the detection mechanism 3 further includes an irradiation member 31. The irradiation member 31 can irradiate the side hole 41. If the light irradiated by the irradiation member 41 cannot penetrate the side hole 31, that is, there is a problem with the side hole 31, and thus the workpiece 4 is unqualified.

[0040] In this embodiment, as mentioned above, the traditional detection process of the workpiece 4 is cumbersome and requires manual detection, resulting in very low efficiency and time-consuming and laborious. Therefore, in this embodiment, the processing, detection, and subsequent series of processes of the workpiece 4 are all automated operations. From this, it can be obtained that the automated operation of the stamping die must be provided with an automatic clamping and automatic transmission device.

[0041] So in this embodiment, as Figure 1 shown, the clamping and conveying mechanism 2 includes a clamping device 20 and a conveying device 21. As the name implies, the clamping device 20 has the function of clamping the workpiece 4 for inspection in this application, and the conveying device 21 has the function of conveying the clamping device 20 clamping the workpiece 4.

[0042] It can be understood that as Figure 1 、 2 shown, the clamping device 20 includes a first clamping portion 200 and a second clamping portion 201. The first clamping portion 200 and the second clamping portion 201 are respectively installed on both sides of the mold body 1, and their heights are both higher than the height of the mold body 1. The first clamping portion 200 and the second clamping portion 201 are respectively connected in cooperation with the conveying device 21. After clamping the workpiece 4, the first clamping portion 200 and the second clamping portion 201 can perform synchronous displacement under the drive of the conveying device 21.

[0043] It can also be understood that a lower die 6 is further provided on the mold body 1. The lower die 6 includes a mold cavity 60. In order to facilitate the qualified workpiece 4 to fall into the mold cavity 60 after detection, the clamping device 20 of the present application is arranged to be driven and clamped at one end and buckled and connected at the other end. In this way, after the workpiece 4 is detected, it does not need to go through cumbersome processes and then fall into the mold cavity 60.

[0044] Therefore, in this embodiment, it is defined that the first clamping portion 200 can drive and clamp the front end of the workpiece 4, and the second clamping portion 201 can be buckled and connected to the tail end of the workpiece 4. There are various specific structures for the first clamping portion 200 to drive and clamp, including but not limited to the following two.

[0045] Structure 1: The first clamping portion 200 includes a first clamping member 2000 and a driving member 2002. The first clamping member 2000 is fixedly connected to the conveying device 21. A through hole is provided on the first clamping member 2000, and the driving member 2002 passes through the through hole and is slidably connected to the first clamping member 2000. The driving member 2002 clamps or releases the workpiece 4 by displacing along the axial direction of the through hole.

[0046] Structure 2: As Figure 6 、 7 shown, the first clamping portion 200 includes a first clamping member 2000, a driving member 2002 and a pushing block 2001. The first clamping member 2000 is fixedly connected to the conveying device 21. A connecting cavity 2004 is provided at the bottom of the first clamping member 2000, and the pushing block 2001 is slidably connected to the first clamping member 2000 through the connecting cavity 2004. The driving member 2002 is arranged on the back of the pushing block 2001. The pushing block 2001 is displaced along the connecting cavity 2004 by the driving of the driving member 2002 to clamp and then release the workpiece 4.

[0047] It should be known that the above two setting methods can both meet the requirements of the present application, and those skilled in the art can choose according to actual needs; in this embodiment, the above Structure 2 is preferably adopted.

[0048] It can be understood that, whether it is Structure 1 or Structure 2, the principle of clamping the workpiece 4 by both structures is to apply pressure to the front end of the workpiece 4, so that its tail end is tightly abutted against the second clamping part 201, and then through the acting force between the driving part 2002 or the pushing block 2001 and the workpiece 4, the workpiece 4 is clamped by the first clamping part 200 and the second clamping part 201. However, the areas of the driving part 2002 and the pushing block 2001 are different, which results in different pressing areas of the two on the workpiece 4. As is well known, the smaller the pressing area, the easier it is for the pressed part to break. When the driving part 2002 and the pushing block 2001 apply the same pressure to the workpiece 4, the contact area between the pushing block 2001 and the workpiece 4 is larger than the contact area of the driving part 2002. Therefore, the connection between the pushing block 2001 and the workpiece 4 is more stable and not prone to breakage.

[0049] It can also be understood that the pressing center point of the pushing block 2001 depends on the driving point of the driving part 2002 on the pushing block 2001. Therefore, in order to make the connection between the pushing block 2001 and the workpiece 4 more stable.

[0050] Therefore, in this embodiment, as Figure 6 shown, the first clamping part 200 further includes a fixing part 2003. The driving part 2002 is slidably connected to the fixing part 2003. The driving part 2002 can drive the center of the pushing block 2001 under the drive of the fixing part 2003, so that the pressing part of the pushing block 2001 is the center, thereby ensuring a more stable connection between the two.

[0051] In this embodiment, as Figure 5 shown, the second clamping part 201 includes a second clamping member 2010. An arc part 2011 is provided at the front end of the second clamping member 2010. An inner concave part 42 is provided at the tail end of the workpiece 4. The shape and position of the arc part 2011 and the inner concave part 42 correspond to each other. At the same time, a side hole 41 is provided at the tail end of the workpiece 4. The irradiation member 31 described above is installed on the second clamping member 2010. After the arc part 2011 is buckled and connected with the tail end of the workpiece 4, an irradiation port 310 is provided at the position corresponding to the side hole 41. After the second clamping member 2010 is buckled and connected with the tail end of the workpiece 4 through the arc part 2011, the irradiation member 31 irradiates, and the light is emitted from the irradiation port 310. If the side hole 41 is in a qualified opening state, the light will be emitted normally; if the light is refolded, it means that the side hole 41 is under-punched or the size is unqualified. It is possible to judge whether the side hole 41 of the workpiece 4 is qualified through the parameter change of the irradiation member 31, and control whether to perform the next step of work.

[0052] In this embodiment, in order to facilitate the staff to timely detect problems with the workpiece 4 and avoid damage to the mold, a detection component is provided on the first clamping portion 200. If the inspection pin 30 inspects the front hole 40 of the workpiece 4 and the front hole 40 is qualified, the position of the workpiece 4 will not change, and the first clamping member 2000 can continue to normally clamp the workpiece 4; if the inspection pin 30 inspects the front hole 40 of the workpiece 4 and the front hole 40 is unqualified, under the action of the inspection pin 30, the position of the workpiece 4 will change, making the first clamping member 2000 unable to normally clamp the workpiece 4. At this time, under the detection of the detection component, the mechanical operation can be stopped in time and an alarm can be issued.

[0053] It can be understood that there are various ways to set the detection component. The detection component can be a pressure sensing device, or a visual detection device, or a light detection device, etc.

[0054] It should be known that the above-mentioned devices can all meet the requirements of this application. Those skilled in the art can select according to actual needs, and the installation method of the detection component is well-known in the art.

[0055] In this embodiment, as Figure 1 shown, the feeding mechanism 2 includes a conveying device 21. The conveying device 21 mainly cooperates with the clamping device 20 to transport the workpiece 4. In order to remove manual labor during the detection process of the workpiece 4, improve production efficiency, and save time and effort.

[0056] Therefore, in this embodiment, the conveying device 21 includes a carrier 212, a sliding member 211, and a guide rail 210. The guide rail 210 is installed on both sides of the mold body 1. The carrier 212 and the sliding member 211 are installed on the guide rails 21 on both sides of the mold body 1. The sliding member 211 and the carrier 212 are fixedly connected and simultaneously cooperate with the guide rail 210. The sliding member 211 can drive the carrier 212 to displace along the guide rail 210. The first clamping portion 200 and the second clamping portion 201 are respectively installed on the carriers 212 corresponding to the front end and the tail end of the workpiece 4, and can perform synchronous displacement under the drive of the carrier 212.

[0057] The above describes the basic principle, main features and advantages of this application. Those skilled in the art should understand that this application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of this application.
