Description

Technical Field

[0001] This utility model relates to the field of stamping die reset detection, and in particular to a stamping die with reset detection function. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces (stamped parts) of the desired shape and size. Stamping dies mainly include dies and punches. The stamping blank is placed on the die, and then stamped by the punch. During this process, a lower ejector cylinder connected to an air compressor maintains a certain back pressure under the action of high-pressure gas. The lower ejector cylinder maintains the same back pressure on the lower ejector plate. The lower ejector plate, on the one hand, works with the punch to keep the stamping blank flat during the stamping process, ensuring the flatness of the resulting part; on the other hand, it ejects the stamped part from the die, facilitating the pickup of the stamped part. After stamping a blank, the lower ejector cylinder must be reset before the next stamping can begin. However, currently, reset is generally checked visually, which is prone to misjudgment. Utility Model Content

[0003] In view of the above problems, this application provides a stamping die with a reset detection function to solve the technical problem that the existing reset detection is generally performed by visual inspection, which is prone to misjudgment.

[0004] To achieve the above objectives, the inventors provide a stamping die with a reset detection function, including a punch assembly, a die assembly, and a sensing assembly. The punch assembly includes a punch; the die assembly includes a lower worktable, a lower die holder, a die, a lower ejector cylinder, a lower ejector plate, and an air compressor. The lower worktable has a through hole, and a lower die holder is mounted on the lower worktable. A first placement groove is formed at the bottom of the lower die holder at the through hole. A die is mounted on the lower die holder, and the groove of the die is located directly below the punch. The lower ejector cylinder is installed in the through hole and slides vertically within the through hole. The output end of the lower ejector cylinder passes through the lower die holder and extends into the groove of the die, connecting with the lower ejector plate. The lower ejector plate slides vertically within the groove of the die. The air compressor is connected to the lower ejector cylinder. The sensing assembly includes a first position sensor, which is installed in the first placement groove. The first position sensor is communicatively connected to the machine tool control system, which controls the machine tool to stop based on the position data of the lower ejector cylinder detected by the first position sensor.

[0005] Unlike existing technologies, the technical solution of this application includes a first position sensor. This first position sensor detects the position of the lower ejector cylinder, thereby determining whether the lower ejector cylinder has reset. The machine tool control system uses the first position sensor to make judgments. Once the first position sensor detects that the lower ejector cylinder has not reset, it immediately stops the machine tool to prevent the stamping die from continuing to work while the lower ejector cylinder is not reset, which could lead to interference and impact, thus protecting the die. In addition, the automatic detection of die reset facilitates the automation of stamping production.

[0006] As one embodiment of this utility model, a first placement groove is provided on each side of the through hole at the bottom of the lower mold base, and two first position sensors are provided, with one first position sensor installed in each first placement groove.

[0007] Thus, by setting two first position sensors to detect the positions of both sides of the lower cylinder, it is possible to ensure that the lower cylinder can be fully reset. Operation continues only when both first position sensors detect a reset; if one first position sensor fails to detect a reset, the machine tool must be stopped immediately. Furthermore, if one first position sensor malfunctions, the other first position sensor can still function normally.

[0008] In one embodiment of this utility model, the first position sensor is a proximity switch.

[0009] Thus, the proximity switch has a simple structure and is easy to use. The proximity switch can be connected to the machine tool control system via a wire. In some embodiments, the first position sensor can also be a micro switch.

[0010] As one embodiment of the present invention, the sensing component further includes a second position sensor and a trigger block. The second position sensor is communicatively connected to the machine tool control system. The die has a second placement groove on one side of its slot. The second position sensor is installed in the second placement groove. The lower top plate has a third placement groove at the corresponding position of the second position sensor. The trigger block is installed in the third placement groove and is used to contact the second position sensor.

[0011] Thus, through the cooperation of the second position sensor and the trigger block, a re-check can be performed when the first position sensor detects a reset; that is, operation can only continue when the first position sensor detects a reset and the trigger block contacts the second position sensor. If the trigger block does not contact the second position sensor, the machine tool control system will still control the machine tool to stop immediately.

[0012] As one embodiment of this utility model, the die has a second placement groove on each side of its slot, and two third placement grooves are also provided corresponding to the second placement grooves. There are two second position sensors and two trigger blocks, with one second position sensor corresponding to one trigger block.

[0013] Thus, by setting two second position sensors and a trigger block, it can be fully guaranteed that the lower top plate returns to its initial position, that is, the lower top cylinder is in the fully reset position.

[0014] In one embodiment of this utility model, the second position sensor is a limit switch.

[0015] Thus, limit switches are simple, reliable, and inexpensive.

[0016] As one embodiment of this utility model, the stamping die with reset detection function also includes an alarm, which is communicatively connected to the machine tool control system.

[0017] Thus, by setting an alarm, an alarm can be issued when the machine tool control system stops the machine tool, so as to remind the staff.

[0018] As one embodiment of this utility model, the punch assembly also includes an upper worktable, an upper die base, and an upper fixing plate. The upper die base is installed below the upper worktable, the upper fixing plate is installed below the upper die base, and the punch is installed below the upper fixing plate.

[0019] Thus, the punch is fixedly installed via the upper worktable, upper mold base, and upper fixing plate.

[0020] As one embodiment of this utility model, the punch assembly also includes an upper backing plate, which is installed below the upper fixing plate and sleeved on the outside of the punch.

[0021] In this way, by setting an upper backing plate to protect the mounting part of the punch, local deformation of the punch can be prevented.

[0022] The above description of the utility model is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0041] According to some embodiments of this application, please refer to Figures 1 to 5 This embodiment relates to a stamping die 100 with a reset detection function, including a punch assembly 1, a die assembly 2, and a sensing assembly 3. The punch assembly 1 includes a punch 11; the die assembly 2 includes a lower worktable 21, a lower die base 22, a die 23, a lower ejector cylinder 24, a lower ejector plate 25, and an air compressor 26. The lower worktable 21 has a through hole 211, and the lower die base 22 is mounted on the lower worktable 21. A first placement groove is opened at the bottom of the lower die base 22 at the through hole 211. The die 23 is mounted on the lower die base 22, and the groove of the die 23 is located directly below the punch 11. The lower ejector cylinder 24 is mounted on the through hole 211. The lower cylinder 24 slides vertically Y within the through hole 211. The output end of the lower cylinder 24 passes through the lower mold base 22 and extends into the slot of the die 23 to connect with the lower top plate 25. The lower top plate 25 slides vertically Y within the slot of the die 23. The air compressor 26 is connected to the lower cylinder 24. The sensing component 3 includes a first position sensor 31, which is installed in the first placement slot. The first position sensor 31 is communicatively connected to the machine tool control system 200. The machine tool control system 200 is used to control the machine tool to stop based on the position data of the lower cylinder 24 detected by the first position sensor 31.

[0042] The output end of the lower ejector cylinder 24 is an ejector rod 241. The ejector rod 241 passes through the lower mold base 22 and extends into the slot of the die cavity 23 and connects with the lower ejector plate 25.

[0043] like Figure 5 As shown, in actual use, the stamping die 100 with reset detection function first places the stamping blank 300 into the stamping die, that is, places the stamping blank 300 on the die cavity 23; second, controls the punch 11 to move downward to perform stamping; third, after the stamping is completed and returns to the initial point, the machine tool control system 200 detects the first position sensor 31; finally, if the first position sensor 31 has no signal, it means that the lower cylinder 24 has not been reset, and the machine tool control system 200 controls the machine tool to stop immediately and controls the alarm to sound an alarm; if the first position sensor 31 has a signal, it means that the lower cylinder 24 has been reset, and the machine tool is ready to perform the next stamping.

[0044] The technical solution of this application includes a first position sensor 31, which detects the position of the lower ejector cylinder 24 to determine whether the lower ejector cylinder 24 has reset. The machine tool control system 200 uses the first position sensor 31 to make judgments. Once the first position sensor 31 detects that the lower ejector cylinder 24 has not reset, it immediately stops the machine tool to prevent the stamping die from continuing to operate while the lower ejector cylinder 24 is not reset, which could lead to interference and impact, thus protecting the die. Furthermore, the automatic detection of die reset facilitates the automation of stamping production.

[0045] According to some embodiments of this application, optionally, such as Figure 2 As shown, the bottom of the lower mold base 22 has a first placement slot on each side of the through hole 211. There are two first position sensors 31, and one first position sensor 31 is installed in each first placement slot.

[0046] Thus, by setting two first position sensors 31 to detect the positions of both sides of the lower cylinder 24, it can be ensured that the lower cylinder 24 can be fully reset. Operation continues only when both first position sensors 31 detect a reset; if one first position sensor 31 detects a failure to reset, the machine tool must be stopped immediately. Furthermore, if one first position sensor 31 malfunctions, the other first position sensor 31 can still perform normal detection.

[0047] According to some embodiments of this application, optionally, the first position sensor 31 is a proximity switch.

[0048] Thus, the proximity switch has a simple structure and is easy to use. The proximity switch can be connected to the machine tool control system 200 via a wire. In some embodiments, the first position sensor 31 can also be a micro switch.

[0049] According to some embodiments of this application, optionally, such as Figure 3 and Figure 4 As shown, the sensing component 3 also includes a second position sensor 32 and a trigger block 33. The second position sensor 32 is communicatively connected to the machine tool control system 200. The die 23 has a second placement groove on one side of its slot, and the second position sensor 32 is installed in the second placement groove. The lower top plate 25 has a third placement groove at the corresponding position of the second position sensor 32, and the trigger block 33 is installed in the third placement groove. The trigger block 33 is used to contact the second position sensor 32.

[0050] Since the output end of the lower ejector cylinder 24 is connected to the lower ejector plate 25, the lower ejector plate 25 also needs to be reset to its initial position when the lower ejector cylinder 24 is reset. Therefore, a second placement groove can be first opened on one side of the cavity of the die 23, and a third placement groove corresponding to the second placement groove can be opened on the lower ejector plate 25 when the lower ejector cylinder 24 is in the reset state. The second placement groove is opened near the top of the die 23, and the third placement groove is opened near the top of the lower ejector plate 25. This means that the trigger block 33 will only contact the second position sensor 32 when the lower ejector plate 25 is reset, thus avoiding misjudgment.

[0051] Thus, through the cooperation of the second position sensor 32 and the trigger block 33, a re-check can be performed when the first position sensor 31 detects a reset. That is, the machine can only continue to operate when the first position sensor 31 detects a reset and the trigger block 33 contacts the second position sensor 32. If the trigger block 33 does not contact the second position sensor 32, the machine tool control system 200 will still control the machine tool to stop immediately.

[0052] According to some embodiments of this application, optionally, such as Figure 3 and Figure 4 As shown, the die 23 has a second placement slot on each side of its slot, and two third placement slots corresponding to the second placement slots are also provided. There are two second position sensors 32 and two trigger blocks 33, with one second position sensor 32 corresponding to one trigger block 33.

[0053] Two second placement slots are symmetrically arranged, and two third placement slots are symmetrically arranged. By setting two second position sensors 32 and trigger blocks 33, it can be fully guaranteed that the lower top plate 25 returns to its initial position, that is, the lower top cylinder 24 is in the fully reset position.

[0054] According to some embodiments of this application, optionally, the second position sensor 32 is a limit switch.

[0055] Thus, limit switches are simple, reliable, and inexpensive.

[0056] According to some embodiments of this application, optionally, the stamping die 100 with reset detection function also includes an alarm, which is communicatively connected to the machine tool control system 200.

[0057] Thus, by setting an alarm, an alert can be issued when the machine tool is stopped by the machine tool control system 200, to notify the operator. The alarm can emit sound and / or light.

[0058] According to some embodiments of this application, optionally, such as Figure 1 and Figure 2As shown, the punch assembly 1 also includes an upper worktable 12, an upper die holder 13, and an upper fixing plate 14. The upper die holder 13 is installed below the upper worktable 12, the upper fixing plate 14 is installed below the upper die holder 13, and the punch 11 is installed below the upper fixing plate 14.

[0059] Thus, the punch 11 is fixedly installed via the upper worktable 12, the upper mold base 13, and the upper fixing plate 14.

[0060] According to some embodiments of this application, optionally, such as Figure 1 and Figure 2 As shown, the punch assembly 1 also includes an upper backing plate 15, which is installed below the upper fixing plate 14 and sleeved on the outside of the punch 11.

[0061] Thus, by setting the upper pad 15 to protect the mounting part of the punch 11, local deformation of the punch 11 is prevented.
