Description

Technical Field

[0001] The present application relates to the field of dies, and in particular to a stamping progressive die for automobile sheet metal parts with a positioning detection mechanism. Background Art

[0002] In the stamping process, the progressive stamping process is used to achieve high-speed, efficient and high-quality stamping production. In the stamping die of precision small sheet metal parts, detection pins are usually used for positioning detection. The misfeeding signal detected by this detection pin can be fed back to force the punch press to brake in time, which is reliable to use.

[0003] However, when stamping large-sized automotive sheet metal structural parts, due to the large size of the stamped parts, the large mold used, the large tonnage and stroke of the selected stamping equipment, and the large inertia and kinetic energy of the stamping machine equipment, the mis-sent signal obtained by the detection pin is difficult to control the emergency braking of the stamping equipment in time, and it is difficult to protect the material belt and the mold. Therefore, it is necessary to develop a positioning detection mechanism suitable for the stamping mold of large sheet metal parts. Utility Model Content

[0004] In order to make the positioning detection mechanism suitable for stamping dies for large sheet metal parts, the present application provides an automobile sheet metal stamping progressive die with a positioning detection mechanism.

[0005] The present application provides a stamping progressive die for automobile sheet metal parts with a positioning detection mechanism, which adopts the following technical solution:

[0006] A stamping progressive die for automobile sheet metal parts with a positioning detection mechanism comprises an upper die base and a lower die base, the lower die base is provided with a limiter, the limiter comprises a first positioner and a second positioner; the feeding direction of the material strip is the width direction of the lower die base; positioning columns are provided at the four corners of the lower die base, the first positioner is arranged on the positioning column, the second positioner is arranged on the positioning column, two of the first positioner and the second positioner are each provided, and the first positioner and the second positioner are arranged in pairs on both sides of the length direction of the lower die base; when the material strip moves to the first positioner, the upper die base starts to move downward, and when the material strip moves to the second positioner, the bottom of the upper die base contacts the material strip.

[0007] By adopting the above technical solution, two first positioners are set to sense whether the material strip moves into the mold. If the material strip is in a horizontal state at this time, the material strip continues to move until the material strip moves to the second positioner. At this time, the bottom of the upper mold base contacts the material strip, and the material strip covers the molding cavity. If the material strip is still in a horizontal state, the material strip continues to be transmitted, the upper mold continues to close the mold, and the material strip is punched to form a sheet metal part; if the material strip tilts during the transmission process, the first positioner senses the tilt of the material strip and sends a signal to stop the stamping machine and interrupt the stamping; the automotive sheet metal stamping progressive die with a positioning detection mechanism can position the material strip and detect whether the material strip is tilted.

[0008] Optionally, the first positioner and the second positioner both include an infrared transmitter and an infrared receiver. When the material belt blocks the infrared light emitted by the infrared transmitter so that the infrared receiver does not receive the infrared signal, the infrared receiver sends a signal to stop the punching machine.

[0009] By adopting the above technical solution, an infrared transmitter and an infrared receiver are set to ensure that the material strip is in a horizontal state when it is fed into the mold. If the material strip is tilted, the infrared beam is blocked, and the infrared receiver sends a signal to stop the punching machine.

[0010] Optionally, a guide groove is provided on one side opposite to the two first positioners; and the infrared light beam emitted by the infrared emitter is located at the upper and lower sides of the guide groove.

[0011] By adopting the above technical solution, a guide groove is set to guide the movement of the material strip to prevent the material strip from tilting; and the infrared light beam emitted by the first positioner is located on the upper and lower sides of the guide groove. When the material strip enters the mold, if it is not in a horizontal state, the infrared light beam is blocked, and the infrared receiver sends a signal to stop the stamping machine.

[0012] Optionally, a guide plate is provided on the side facing the positioning column, and the guide plate is abutted against the upper mold base.

[0013] By adopting the above technical solution, when the mold is closed, the upper mold base can be accurately closed when the guide plate abuts against the upper mold base.

[0014] Optionally, a flip storage device is provided on the upper mold base and the lower mold base.

[0015] By adopting the above technical solution, a flip-type storage device is provided to buckle the upper mold base and the lower mold base to fix the two when the mold is not in use.

[0016] Optionally, a storage assembly is provided between the upper die base and the lower die base, the storage assembly includes a bottom plate and a plurality of nitrogen springs arranged on the bottom plate, and the lower die base is provided with a plurality of accommodating grooves for accommodating the nitrogen springs.

[0017] By adopting the above technical solution, a storage assembly is provided to facilitate the storage of the mold. When the mold is not in use, a base plate is placed between the upper mold base and the lower mold base, and the nitrogen spring is accommodated in the accommodating groove, so that the upper mold base is supported without being directly pressed on the lower mold base, thereby reducing damage to the lower mold base.

[0018] Optionally, weight-reducing grooves are provided on the upper die base and the lower die base.

[0019] By adopting the above technical solution, a weight-reducing groove is provided to reduce the overall weight of the mold, thereby facilitating the installation of the mold.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. Two first positioners are set to sense whether the material strip moves into the mold. If the material strip is in a horizontal state at this time, the material strip continues to move until it moves to the second positioner. At this time, the bottom of the upper mold base contacts the material strip, and the material strip covers the molding cavity. If the material strip is still in a horizontal state, the material strip continues to be transmitted, the upper mold continues to close the mold, and the material strip is punched to form a sheet metal part; if the material strip tilts during the transmission process, the first positioner senses the tilt of the material strip and sends a signal to stop the punching machine and interrupt the punching; the automobile sheet metal stamping progressive die with a positioning detection mechanism can position the material strip and detect whether the material strip is tilted;

When the mold is not in use, a base plate is placed between the upper mold base and the lower mold base, and the nitrogen spring is accommodated in the accommodation groove, so that the upper mold base is supported without directly pressing on the lower mold base, thereby reducing damage to the lower mold base;

Figure 1 and Figure 2 The stamping progressive die for automobile sheet metal parts with a positioning detection mechanism includes an upper die base 1 and a lower die base 2. The upper die base 1 is installed on the slider of the punching machine, and the lower die base 2 is installed on the workbench of the punching machine. A limiter 3 is installed on the lower die base 2, and the limiter 3 includes two first positioners 31 and two second positioners 32. The feeding direction of the material strip is the width direction of the lower die base 2. Positioning columns 4 are fixed at the four corners of the lower die base 2, the first positioner 31 is installed on the positioning column 4, and the second positioner 32 is installed on the positioning column 4. The first positioner 31 and the second positioner 32 are installed on both sides of the length direction of the lower die base 2 in pairs; when the material strip moves to the first positioner 31, the upper die base 1 starts to move downward, and when the material strip moves to the second positioner 32, the bottom of the upper die base 1 contacts the material strip.

[0032] Reference Figure 2 The first positioner 31 and the second positioner 32 both include an infrared transmitter 5 and an infrared receiver 6. When the material strip blocks the infrared light emitted by the infrared transmitter 5 so that the infrared receiver 6 does not receive the infrared signal, the infrared receiver 6 sends a signal to stop the punching machine.

[0033] Reference Figure 2 A guide groove 7 is provided on one side opposite to the two first positioners 31 , and the two sides of the feed belt are accommodated in the guide groove 7 . The infrared beams emitted by the first positioners 31 are located at the upper and lower sides of the guide groove 7 .

[0034] Reference Figure 2 and Figure 3 A guide plate 8 is fixed on the opposite side of the positioning column 4. In the embodiment of the present application, eight guide plates 8 are installed, and the guide plates 8 are abutted against the upper die base 1. The mounting plate on the upper die base 1 corresponding to the lower die base 2 is also installed with a corresponding guide plate 8.

[0035] Reference Figure 1A flip storage device 9 is installed on the upper die base 1 and the lower die base 2.

[0036] Reference Figure 1 and Figure 4 A storage assembly 10 is installed between the upper die base 1 and the lower die base 2.

[0038] The implementation principle of the automotive sheet metal stamping progressive die with a positioning detection mechanism in an embodiment of the present application is as follows: two first positioners 31 are set to sense whether the material strip moves into the mold. If the material strip is in a horizontal state at this time, the material strip continues to move until the material strip moves to the second positioner 32. At this time, the bottom of the upper mold base 1 contacts the material strip, and the material strip covers the molding cavity. If the material strip is still in a horizontal state, the material strip continues to be transmitted, the upper mold continues to close the mold, and the material strip is stamped to form a sheet metal part. If the material strip is tilted during the transmission process, the first locator 31 senses the tilt of the material strip and sends a signal to stop the punching machine and interrupt the punching; the automobile sheet metal stamping progressive die with a positioning detection mechanism can position the material strip and detect whether the material strip is tilted; the material strip is continuously detected to see whether it is in a horizontal state during the process of being transmitted from the first locator 31 to the second locator 32, and after the material strip is punched, the unprocessed material strip continues to be transmitted from the first locator 31 to the second locator 32, the upper die is driven upward by the punching machine and is driven to the molding cavity again when the material strip is transmitted to the second locator 32 (that is, the bottom of the upper die seat 1 is in contact with the material strip) for the next punching, and so on.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
