Description

Technical Field

[0001] This application relates to the field of automotive processing equipment technology, and in particular to a trigger-type action structure for a stamping die for an upper inner panel of an automobile. Background Technology

[0002] Stamping dies are a type of process equipment used in stamping to process materials into workpieces or semi-finished products. They typically consist of an upper die and a lower die. The upper die presses the profile placed on the lower die to form the workpiece or semi-finished product, making it a key piece of equipment in industrial production. Stamping dies can be used to produce parts using mass-produced rolled steel plates or strips from metallurgical plants as raw materials, and the process does not require heating, offering advantages such as high production efficiency, good quality, and low cost.

[0003] Currently, in order to accurately control the stamping quality of the upper die on the upper die of the lower die, a fixed contact switch is usually bolted to the upper or lower die. The contact switch can be used to accurately control the stamping distance of the upper die, thereby extending the service life of the die.

[0004] However, during the production of workpieces, the thickness of the profiles is sometimes different. In order to ensure the stamping quality of the workpieces, workers need to adjust the position of the contact switch to adapt to profiles of different thicknesses. However, manual adjustment requires repeated debugging of the equipment, which usually takes a long time during the debugging process. Consequently, the equipment cannot be put into production for a long time, which is a shortcoming. Utility Model Content

[0005] To address the issue of lengthy adjustment times required for equipment, this application provides a trigger-type action structure for stamping dies for automotive upper inner panels.

[0006] The trigger-type action structure of the stamping die for the inner panel of an automobile provided in this application adopts the following technical solution:

[0007] A trigger-type action structure for stamping an inner panel of an automobile includes a moving die and a stationary die. The moving die is located directly above the stationary die. A trigger block and a measuring element are provided on the moving die. The measuring element is used to measure the thickness of the profile. An adjusting column is vertically slidably provided on the stationary die. A lifting assembly for driving the adjusting column to slide is provided on the stationary die. A trigger frame is provided on the adjusting column. A trigger rod is rotatably provided on the trigger frame. A proximity switch electrically connected to a control system is provided on the trigger frame. When the trigger block abuts against and pushes one end of the trigger rod to rotate, the other end of the trigger rod will trigger the proximity switch. A reset element for driving the trigger rod to reset is provided on the trigger frame.

[0008] By adopting the above technical solution, the worker first measures the thickness of the profile using a measuring device. Then, the lifting assembly drives the adjusting column to slide vertically. The adjusting column changes the position of the trigger rod and the proximity switch through the trigger frame. Then, as the moving mold presses against the stationary mold, the trigger block pushes the trigger rod to rotate. The rotating trigger rod triggers the proximity switch. At this time, the moving mold completely presses the profile against the stationary mold and stops moving, thereby accurately controlling the stamping quality of the workpiece. This process does not require the worker to adjust the equipment multiple times, greatly reducing the impact of adjusting the equipment on the production of the workpiece.

[0009] Optionally, the reset component includes a rotating shaft rotatably mounted on the trigger frame, a trigger rod mounted on the rotating shaft, a reset rod mounted on the rotating shaft, a trigger block for striking the reset rod, the reset rod being parallel to the trigger rod, and a counterweight mounted on the reset rod. When the moving mold separates from the stationary mold, the counterweight causes the reset rod to be arranged horizontally.

[0010] By adopting the above technical solution, when the moving mold and the stationary mold are separated, the trigger block and the reset rod are separated. At this time, the counterweight block drives the rotating shaft to rotate under the action of gravity. The rotating shaft will drive the trigger rod to rotate synchronously, thereby resetting the trigger rod and preparing for the next trigger rod to trigger the proximity switch.

[0011] Optionally, a tension spring is provided between the side of the counterweight facing away from the moving mold and the trigger frame.

[0012] By adopting the above technical solution, when the moving mold presses against the stationary mold, the trigger block pushes the reset rod to rotate. The rotating reset rod drives the counterweight block to rotate synchronously. At this time, the tension spring is stretched and deformed. When the moving mold and the stationary mold separate, the tension spring restores its deformation and pulls the counterweight block to rotate around the axis to reset. This reduces the occurrence of situations where the friction between the axis and the trigger frame is too large, causing the reset rod to fail to reset.

[0013] Optionally, the ranging component includes a material rack mounted on the moving mold, a measuring rod with an L-shaped cross-section detachably mounted on the material rack, a vertically slidable abutment post mounted on the measuring rod for abutting the upper surface of the profile, a sliding groove provided on the measuring rod for the abutment post to slide in, a pressure sensor electrically connected to the control system being mounted in the sliding groove of the measuring rod, and a measuring spring supporting the abutment post and the sensing end of the pressure sensor.

[0014] By adopting the above technical solution, after the worker places the newly replaced profile on the material rack, the worker installs the measuring rod on the material rack. The measuring spring will press the abutment post against the profile. At this time, the pressure sensor will feed the signal back to the control system, thereby quickly obtaining the thickness of the profile.

[0015] Optionally, the cross-section of the adjusting column is polygonal, the lifting assembly includes a lifting tube disposed on the stationary mold, the lifting tube is slidably sleeved on the adjusting column, an mounting plate is disposed on the upper surface of the stationary mold, a lifting screw is threadedly connected to the mounting plate, the lifting screw slides vertically through the upper and lower surfaces of the stationary mold, the adjusting column is rotatably connected to one end of the lifting screw, and a rotating component is disposed on the stationary mold to drive the lifting screw to rotate.

[0016] By adopting the above technical solution, when the control system receives the width information of the profile, the rotating component drives the lifting screw to rotate. Since the mounting plate and the lifting tube cannot move, the rotating lifting screw will push the adjusting column to slide vertically, thereby achieving the effect of adjusting the position of the adjusting column and the trigger rod.

[0017] Optionally, the rotating component includes a slide rod coaxially mounted on the lifting screw, the slide rod being located at the end of the lifting screw facing away from the adjusting column, the slide rod having a polygonal cross-section, a bracket being provided on the lower surface of the stationary mold, a drive disk coaxially mounted on the bracket and coaxially mounted with the lifting screw, a driven gear ring being coaxially sleeved on the drive disk, the slide rod sliding through the drive disk, a drive motor electrically connected to the control system being provided on the stationary mold, and a drive gear meshing with the driven gear ring being provided on the output shaft of the drive motor.

[0018] By adopting the above technical solution, when the control system receives the width information of the profile, the control system starts the drive motor. The output shaft of the drive motor drives the drive gear to rotate a rated number of times. The drive gear drives the drive disc to rotate through the driven gear ring. Since the positions of the drive disc and the mounting plate cannot be moved, the lifting screw will drive the slide rod to slide in the vertical direction. The slide rod slides relative to the drive disc, thereby achieving the effect of the lifting screw pushing the adjusting column to slide.

[0019] Optionally, a support spring is provided between the adjusting column and the mounting plate.

[0020] By adopting the above technical solution, the possibility of the regulating column automatically descending is reduced.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The worker first measures the thickness of the profile using a measuring device. Then, the lifting assembly drives the adjusting column to slide vertically. The adjusting column changes the position of the trigger rod and the proximity switch through the trigger frame. Then, as the moving mold presses against the stationary mold, the trigger block pushes the trigger rod to rotate. The rotating trigger rod triggers the proximity switch. At this time, the moving mold completely presses the profile against the stationary mold and stops moving. This accurately controls the stamping quality of the workpiece. This process does not require the worker to adjust the equipment multiple times, greatly reducing the impact of equipment adjustment on the production of workpieces.

[0023] 2. After the worker places the newly replaced profile on the material rack, the worker installs the measuring rod on the material rack. The measuring spring will press the abutment post against the profile. At this time, the pressure sensor will feed the signal back to the control system, thereby quickly determining the thickness of the profile.

[0024] 3. When the control system receives the width information of the profile, the control system starts the drive motor. The output shaft of the drive motor drives the drive gear to rotate a rated number of times. The drive gear drives the drive disc to rotate through the driven gear ring. Since the position of the drive disc and the mounting plate cannot be moved, the lifting screw will drive the slide rod to slide in the vertical direction. The slide rod slides relative to the drive disc, thereby realizing the effect of the lifting screw pushing the adjusting column to slide. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0032] This application discloses a trigger-type action structure for stamping a stamping die for an automotive upper inner panel.

[0033] Reference Figure 1 A trigger-type action structure for stamping an inner panel of an automobile includes a moving die 2 and a stationary die 3. The moving die 2 is located directly above the stationary die 3. A trigger block 4 and a measuring element 5 are arranged on the moving die 2. The measuring element 5 is used to measure the thickness of the profile 1.

[0034] Reference Figure 2 The measuring component 5 includes a material rack 51 bolted to the moving mold 2. A measuring rod 52 with an L-shaped cross-section is bolted to the material rack 51. An abutment post 53 is vertically slidably arranged on the measuring rod 52. The abutment post 53 is used to abut against the upper surface of the profile 1.

[0035] Reference Figure 2 The measuring rod 52 has a sliding groove 54 for the sliding of the abutment post 53. A pressure sensor 55 electrically connected to the control system is bonded in the sliding groove 54 of the measuring rod 52. A measuring pressure spring 56 supports the abutment post 53 and the sensing end of the pressure sensor 55.

[0036] The worker first places the profile 1 on the material rack 51, and then fixes the measuring rod 52 to a fixed position on the material rack 51 with bolts. At this time, the measuring spring 56 will press the abutment post 53 onto the profile 1. At the same time, the pressure sensor 55 will feed back the signal corresponding to when the abutment post 53 stops moving to the control system. The control system will quickly determine the thickness of the profile 1 based on the signal.

[0037] Reference Figure 1 A polygonal cross-section adjustment column 6 is vertically slidably arranged on the stationary mold 3, and a lifting assembly 7 for driving the adjustment column 6 to slide is arranged on the stationary mold 3.

[0038] Reference Figure 1 and Figure 3 The lifting assembly 7 includes a lifting pipe 71 bolted to the upper surface of the stationary mold 3. The lifting pipe 71 is slidably sleeved on the adjusting column 6. An mounting plate 72 is bolted to the upper surface of the stationary mold 3. A support spring 13 supports the adjusting column 6 and the mounting plate 72.

[0039] Reference Figure 4 and Figure 5 A lifting screw 73 is threaded onto the mounting plate 72. The lifting screw 73 slides vertically through the upper and lower surfaces of the stationary mold 3. The bottom of the adjusting column 6 is rotatably connected to the top of the lifting screw 73. A rotating component 74 is arranged on the stationary mold 3 to drive the lifting screw 73 to rotate.

[0040] Reference Figure 1 , Figure 4 and Figure 5 The rotating component 74 includes a slide rod 741 coaxially welded to the bottom of the lifting screw 73. The slide rod 741 is located at the end of the lifting screw 73 facing away from the adjusting column 6. The cross-section of the slide rod 741 is polygonal. A bracket 742 is bolted to the lower surface of the stationary mold 3. A drive disk 743 coaxial with the lifting screw 73 is rotatably connected to the bracket 742.

[0041] Reference Figure 5 A driven gear ring 744 is coaxially sleeved on the drive disk 743. A slide rod 741 slides through the drive disk 743. A drive motor 745 electrically connected to the control system is bolted to the stationary mold 3. An active gear 746 that meshes with the driven gear ring 744 is welded to the output shaft of the drive motor 745.

[0042] When the control system receives the width information of profile 1, the control system starts the drive motor 745. The output shaft of the drive motor 745 drives the drive gear 746 to rotate a rated number of times. The drive gear 746 drives the driven gear ring 744 to rotate. The driven gear ring 744 drives the drive disk 743 to rotate synchronously.

[0043] Since the positions of the drive plate 743 and the mounting plate 72 cannot be moved, the lifting screw 73 will drive the slide bar 741 to slide vertically. The top of the lifting screw 73 pushes the adjusting column 6 to slide vertically, so that the adjusting column 6 slides vertically to the distance corresponding to the thickness of the profile 1.

[0044] Reference Figure 5 A trigger frame 8 is bolted to the adjusting column 6, a trigger rod 9 is rotatably connected to the trigger frame 8, and a proximity switch 10 electrically connected to the control system is bolted to the trigger frame 8. When the trigger block 4 abuts against and pushes one end of the trigger rod 9 to rotate, the other end of the trigger rod 9 will trigger the proximity switch 10. A reset component 11 for driving the trigger rod 9 to reset is arranged on the trigger frame 8.

[0045] Reference Figure 4 and Figure 5 The reset component 11 includes a rotating shaft 111 rotatably connected to the trigger frame 8, a trigger rod 9 welded to the rotating shaft 111, a reset rod 112 welded to the rotating shaft 111, a trigger block 4 for impacting the reset rod 112, the reset rod 112 being parallel to the trigger rod 9, a counterweight block 113 integrally formed on the reset rod 112, a tension spring 12 connecting the side of the counterweight block 113 facing away from the moving mold 2 to the trigger frame 8, and when the moving mold 2 separates from the stationary mold 3, the counterweight block 113 causes the reset rod 112 to be arranged horizontally.

[0046] During the process of pressing the profile 1 onto the stationary mold 3 by the moving mold 2, the trigger block 4 will push the reset rod 112 and the trigger rod 9 to rotate synchronously. The reset rod 112 drives the counterweight block 113 to rotate synchronously. At this time, the tension spring 12 is stretched and deformed until the trigger rod 9 triggers the proximity switch 10. At this time, the moving mold 2 stops moving and the profile 1 is stamped.

[0047] When the moving mold 2 separates from the stationary mold 3, the trigger block 4 separates synchronously with the trigger rod 9 and the reset rod 112. The tension spring 12 restores its deformation and pulls the counterweight block 113 to rotate around the axis of the rotating shaft 111 until the moving mold 2 and the stationary mold 3 are completely separated. At this time, the counterweight block 113 drives the trigger rod 9 and the reset rod 112 to reset, preparing for the trigger rod 9 to trigger the proximity switch 10 next time.

[0048] The implementation principle of the trigger-type action structure of the stamping die for the inner panel of an automobile in this application embodiment is as follows: The worker first places the profile 1 on the material rack 51, and then fixes the measuring rod 52 to a fixed position on the material rack 51 with bolts. At this time, the measuring spring 56 will press the abutment post 53 onto the profile 1, and the pressure sensor 55 will feed back the signal corresponding to when the abutment post 53 stops moving to the control system. The control system will quickly determine the thickness of the profile 1 based on the signal.

[0049] When the control system receives the width information of profile 1, the control system starts the drive motor 745. The output shaft of the drive motor 745 drives the drive gear 746 to rotate a rated number of times. The drive gear 746 drives the driven gear ring 744 to rotate. The driven gear ring 744 drives the drive disk 743 to rotate synchronously.

[0050] Since the positions of the drive plate 743 and the mounting plate 72 cannot be moved, the lifting screw 73 will drive the slide bar 741 to slide vertically. The top of the lifting screw 73 pushes the adjusting column 6 to slide vertically, so that the adjusting column 6 slides vertically to the distance corresponding to the thickness of the profile 1.

[0051] During the process of pressing the profile 1 onto the stationary mold 3 by the moving mold 2, the trigger block 4 will push the reset rod 112 and the trigger rod 9 to rotate synchronously. The reset rod 112 drives the counterweight block 113 to rotate synchronously. At this time, the tension spring 12 is stretched and deformed until the trigger rod 9 triggers the proximity switch 10. At this time, the moving mold 2 stops moving and the profile 1 is stamped.

[0052] When the moving mold 2 separates from the stationary mold 3, the trigger block 4 separates synchronously with the trigger rod 9 and the reset rod 112. The tension spring 12 restores its deformation and pulls the counterweight block 113 to rotate around the axis of the rotating shaft 111 until the moving mold 2 and the stationary mold 3 are completely separated. At this time, the counterweight block 113 drives the trigger rod 9 and the reset rod 112 to reset, preparing for the trigger rod 9 to trigger the proximity switch 10 next time.

[0053] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
