Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and in particular to a stamping die and metal parts processing system. Background Technology

[0002] In the metal parts processing, there are some steps where the strip material needs to be stamped.

[0003] In related technologies, when stamping a strip material, the strip is conveyed to the stamping area of ​​the stamping die. The upper and lower dies of the stamping die assembly are driven to move closer to each other to complete the stamping of the strip material in the stamping area. After the strip material is conveyed to the stamping area, its position often shifts due to errors. In order to improve the stamping accuracy of the stamping die, positioning holes are usually provided on the strip material, and positioning pins are provided on the upper die. As the upper die moves closer to the lower die, the positioning pins can pass through the positioning holes to guide the position of the strip material.

[0004] However, during the process of guiding the strip, the positioning post will pull on the strip, which will cause the strip to deform. The greater the positional deviation of the strip in the stamping zone, the greater the deformation of the strip when the positioning post guides it. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art. The first aspect of this invention provides a stamping die, which, when used to stamp strip, results in less deformation of the strip. The second aspect of this invention also provides a metal parts processing system.

[0006] According to the first aspect of the present invention, a stamping die includes an upper die, a lower die, a detection module, and a drive module. A stamping area extending along a first horizontal direction is formed between the lower die and the upper die. The detection module is located at the tail end of the stamping area and includes a mounting frame, a sensor, and a reset structure. The sensor is buoyantly mounted on the mounting frame along the first horizontal direction. The detection end of the sensor can abut and limit the material strip in the stamping area in the first horizontal direction. The reset structure is connected to the sensor and the mounting frame respectively and is used to reset the sensor. The drive module is connected to at least one of the upper die and the lower die, and the drive module is electrically connected to the sensor. The drive module can drive the upper die and the lower die to move closer to each other when the pressure detected by the sensor reaches a preset value, so as to cooperate in stamping the material strip in the stamping area.

[0007] The stamping die described in this utility model has at least the following beneficial effects: In the stamping die assembly of this application, after the strip enters the stamping zone along the first horizontal direction, as the strip penetrates deeper into the stamping zone, its end can abut against the sensor located at the tail end of the stamping zone, squeezing the sensor's detection end. When the pressure value detected by the sensor reaches a preset value, it indicates that the strip has moved into position within the stamping zone. At this time, the drive module can drive the upper and lower dies to move closer to each other to stamp the strip within the stamping zone. Compared to using the positioning pins on the upper die and the positioning holes on the strip to guide the strip, using the stamping die assembly of this application to stamp the strip reduces the pulling force on the strip. Simultaneously, the reset structure ensures that the sensor can reset after each detection, guaranteeing the accuracy of each strip detection by the sensor.

[0008] According to the stamping die of the first aspect of the present invention, the reset structure is a spring, which extends along a first horizontal direction and is connected to a sensor and a mounting bracket at opposite ends in the first horizontal direction, respectively.

The sensor is buoyantly disposed at one end of the connecting rod near the stamping area along the first horizontal direction. A spring is sleeved on the connecting rod, and the opposite ends of the spring abut against the sensor and the first mounting base, respectively.

[0010] According to the stamping die of the first aspect of the present invention, the mounting bracket further includes a second mounting seat and a third mounting seat. The two ends of the second mounting seat in the first horizontal direction are respectively connected to the lower die and the third mounting seat. The end of the third mounting seat in the second horizontal direction that is away from the second mounting seat is connected to the first mounting seat. The second horizontal direction and the first horizontal direction are set at a certain angle.

[0011] According to the stamping die of the first aspect of the present invention, the first mounting base is detachably connected to the third mounting base via a first threaded connector.

The first abutting surface and the second abutting surface are fitted together, and the first abutting surface is parallel to the extension direction of the first threaded connector.

[0013] According to the stamping die of the first aspect of the present invention, the second mounting base and the third mounting base are detachably connected by a plurality of second threaded connectors.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] The following is for reference. Figures 1 to 4 The stamping die of this application is described in detail.

[0025] refer to Figures 1 to 3 According to an embodiment of the present invention, a stamping die includes an upper die 100, a lower die 200, a detection module 300, and a drive module; a stamping area 101 extending along a first horizontal direction is formed between the lower die 200 and the upper die 100; the detection module 300 is disposed at the tail end of the stamping area 101, and the detection module 300 includes a mounting bracket 310, a sensor 320, and a reset structure; the sensor 320 is buoyantly disposed on the mounting bracket 310 along the first horizontal direction, and the detection end of the sensor 320 is capable of... The material strip in the stamping zone 101 is stopped and limited in the first horizontal direction. The reset structure is connected to the sensor 320 and the mounting bracket 310 respectively, and is used to reset the sensor 320. The drive module is connected to at least one of the upper die 100 and the lower die 200, and the drive module is electrically connected to the sensor 320. When the pressure detected by the sensor 320 reaches a preset value, the drive module can drive the upper die 100 and the lower die 200 to move closer to each other to cooperate in stamping the material strip in the stamping zone 101.

[0026] For example, such as Figures 1 to 3 As shown, the stamping die includes an upper die 100, a lower die 200, a detection module 300, and a drive module. The upper die 100 is located above the lower die 200, and a stamping area 101 extending forward and backward is formed between the upper die 100 and the lower die 200. The detection module 300 is located on the lower die 200 and at the tail end of the stamping area 101. The detection module 300 includes a mounting bracket 310, a sensor 320, and a reset structure. The sensor 320 is floatingly mounted on the mounting bracket 310 in the forward and backward direction. The reset structure is connected to the mounting bracket 310 and the sensor 320 respectively, and is used to provide a reset force to keep the sensor 320 moving forward. The drive module is connected to at least one of the upper die 100 and the lower die 200.

[0027] When the stamping module of this application is working, the strip can move from front to back to enter the stamping zone 101. When the strip moves to the end of the stamping zone 101, it can abut against the detection end of the sensor 320 and push the sensor 320 to float backward. During this process, the pressure between the sensor 320 and the strip gradually increases. When the pressure detected by the sensor 320 reaches the preset value, it indicates that the strip has moved to the correct position in the stamping zone 101. At this time, the drive module drives the upper die 100 and the lower die 200 to move closer to each other to complete the stamping of the strip.

[0028] It is understood that in the stamping module of this application, when the strip enters the stamping zone 101, when the pressure between the strip and the sensor 320 reaches a preset value, it means that the strip has moved into place in the stamping zone 101. During the whole process, the deformation of the strip can be smaller.

[0029] It is understandable that the reset structure is designed so that the sensor 320 can be reset after each time it completes the position detection of the strip. This ensures that the strip is in the same position in the stamping zone 101 each time the pressure between the strip and the sensor 320 reaches the preset value, thereby further improving the stamping accuracy of the strip by the stamping module of this application.

[0030] In some embodiments of this utility model, reference is made to Figures 2 to 4 The reset structure is a spring 330, which extends along the first horizontal direction and is connected to the sensor 320 and the mounting bracket 310 at opposite ends in the first horizontal direction, respectively.

[0031] Understandably, the Spring 330 has a simple structure and is inexpensive.

[0032] In some embodiments of this utility model, the mounting bracket 310 includes a connecting rod 311 and a first mounting base 312. The connecting rod 311 extends along a first horizontal direction and is mounted on the first mounting base 312. The sensor 320 is buoyantly disposed at one end of the connecting rod 311 near the stamping area 101 along the first horizontal direction. A spring 330 is sleeved on the connecting rod 311, and the opposite ends of the spring 330 abut against the sensor 320 and the first mounting base 312, respectively.

[0033] For example, such as Figure 3 and Figure 4 As shown, the mounting bracket 310 includes a connecting rod 311 and a first mounting base 312. The connecting rod 311 extends in the front-rear direction, and the rear end of the connecting rod 311 is connected to the first mounting base 312. The sensor 320 is floatingly mounted on the front end of the connecting rod 311 in the front-rear direction. The spring 330 is sleeved on the connecting rod 311, with the front end of the spring 330 abutting against the sensor 320 and the rear end of the spring 330 abutting against the first mounting base 312.

[0034] It is understandable that the connecting rod 311 is designed with the spring 330 sleeved on it. Under the guidance of the connecting rod 311, the spring 330 can deform stably in the front-back direction, thereby enabling the spring 330 to stably push the sensor 320 forward to reset.

[0035] In some embodiments of this utility model, the mounting bracket 310 further includes a second mounting base 313 and a third mounting base 314. The two opposite ends of the second mounting base 313 in the first horizontal direction are respectively connected to the lower mold 200 and the third mounting base 314. The end of the third mounting base 314 facing away from the second mounting base 313 in the second horizontal direction is connected to the first mounting base 312. The second horizontal direction is set at a certain angle from the first horizontal direction.

[0036] For example, such as Figure 3 and Figure 4 As shown, the mounting bracket 310 also includes a second mounting base 313 and a third mounting base 314. The second mounting base 313 extends in the front-to-back direction, and the third mounting base 314 extends in the left-to-right direction. The front end of the second mounting base 313 is connected to the lower die 200, the rear end of the second mounting base 313 is connected to the left end of the third mounting base 314, and the right end of the third mounting base 314 is connected to the first mounting base 312. The sensor 320 is located at the rear end of the stamping area 101.

[0037] It is understandable that by setting the second mounting base 313 and the third mounting base 314, on the one hand, the mounting bracket 310 can be connected on the lower die 200. On the other hand, the setting of the third mounting base 314 allows the sensor 320 to be located at the tail end of the stamping area 101, while the second mounting base 313 can be moved away from the tail end of the stamping area 101 in the horizontal direction, so as to reduce the interference of the second mounting base 313 on the strip.

[0038] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 The first mounting base 312 is detachably connected to the third mounting base 314 via the first threaded connector 301.

[0039] Understandably, since the first mounting base 312 is detachably connected to the third mounting base 314 via the first threaded connector 301, the operator can detach and install the first mounting base 312 on the third mounting base 314 by removing and installing the first threaded connector 301. This makes it more convenient for the operator to replace the sensor 320, and the operator can replace the sensor 320 with a sensor of different specifications according to the specifications of the material strip.

[0040] It is understandable that the first threaded connector 301 can be a bolt, screw, or other connector.

[0041] It should be noted that since the first mounting base 312 and the third mounting base 314 are connected only by a single first threaded connector 301, the first mounting base 312 is prone to rotate relative to the third mounting base 314 about the axis of the first threaded connector 301.

[0042] Based on the above problems, in a further embodiment of the present invention, the first mounting base 312 is provided with a first abutting surface 312a, and the third mounting base 314 is provided with a second abutting surface 314a. The first abutting surface 312a and the second abutting surface 314a are fitted together, and the first abutting surface 312a is parallel to the extension direction of the first threaded connector 301.

[0043] For example, such as Figure 4 As shown, the first threaded connector 301 extends in the front-to-back direction, the first mounting base 312 has a horizontal first abutting surface 312a, and the third mounting base 314 has a horizontal second abutting surface 314a, with the first abutting surface 312a and the second abutting surface 314a in contact.

[0044] It is understandable that, since the first abutting surface 312a and the second abutting surface 314a are fitted together, the second abutting surface 314a can prevent the first mounting base 312 from rotating about the axis of the first threaded connector 301.

[0045] In some embodiments of this utility model, the second mounting base 313 and the third mounting base 314 are detachably connected by a plurality of second threaded connectors 302.

[0046] For example, such as Figure 3 and Figure 4 As shown, the second mounting base 313 and the third mounting base 314 are detachably connected by two second threaded connectors 302, and the two second threaded connectors 302 are spaced apart in the left-right direction.

[0047] Understandably, the detachable connection between the second mounting base 313 and the third mounting base 314 allows the second mounting base 313 and the third mounting base 314 to be manufactured separately, thereby reducing the manufacturing difficulty of the entire mounting bracket 310.

[0048] Understandably, the second threaded connector 302 can be a bolt, screw, or other connector.

[0049] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 The second mounting base 313 and the lower mold 200 are detachably connected by a third threaded connector 303. There are two third threaded connectors 303, which are distributed at intervals in the left and right directions.

[0050] It is understandable that the third threaded connector 303 can be a bolt, screw or other connector.

[0051] In some embodiments of this utility model, the lower die 200 is provided with two sets of guide post groups spaced apart, and the stamping area 101 is located between the two sets of guide post groups. Each set of guide post groups includes multiple guide posts 210 spaced apart along the first horizontal direction. The guide post 210 is provided with an annular guide groove 211. The guide groove 211 allows the edge of the material strip to extend into it, and the guide groove 211 is set at the same height as the sensor 320.

[0052] For example, such as Figure 2 As shown, the lower die 200 is provided with two sets of guide pillars distributed on the left and right. The stamping area 101 is located between the two sets of guide pillars. Each set of guide pillars includes multiple guide pillars 210 distributed at intervals along the front and back direction. The guide pillars 210 extend in the vertical direction and are provided with annular guide grooves 211.

[0053] It is understandable that after the strip enters the stamping area 101 from front to back, the left edge of the strip can pass through the guide groove 211 of the guide post 210 on the left, and the right edge of the strip can pass through the guide groove 211 of the guide post 210 on the right. Thus, with the cooperation of the various guide grooves 211, the strip can move accurately in the front-back direction.

[0054] In some embodiments of this utility model, the upper mold 100 is provided with positioning pins adapted to the positioning holes on the material strip.

[0055] It should be noted that the sensor 320 inevitably has errors during operation, and under such circumstances, the material strip will have a certain offset within the positioning area.

[0056] It is understandable that by setting a positioning post on the upper die 100 and adapting the positioning post to the positioning hole on the strip, the positioning post can pass through the positioning hole when the upper die 100 and the lower die 200 approach each other, thereby correcting the deviation of the strip and enabling the stamping die of this application to accurately complete the stamping of the strip.

[0057] The metal processing system according to the second aspect of the present invention includes the stamping die provided in the first aspect of the present invention.

[0058] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
