Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to an automobile stamping die with a protective structure. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during the cold stamping process. This is called a cold stamping die (commonly known as a cold die). Stamping is a pressure processing method that uses a die mounted on a press at room temperature to apply pressure to the material, causing it to separate or plastically deform, thereby obtaining the desired part.

[0003] The existing stamping dies have poor protection. During stamping, if the stamped part does not separate from the upper die but moves with the upper die, the stamped part may fly out under the action of pressure due to partial deviation during the next stamping, causing safety hazards.

[0004] In view of the above problems, an improved automobile stamping die with a protective structure is now designed. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 4 In the embodiment of the utility model, the automobile stamping die with a protective structure includes a box body 1, a lower die 3 is installed on the upper end of the box body 1, a bracket 7 is installed on the upper end of the side wall of the box body 1, a hydraulic telescopic rod 8 is vertically installed on the bracket 7, and a mounting plate 5 is horizontally installed on the output end of the hydraulic telescopic rod 8, an upper die 15 used in conjunction with the lower die 3 is installed on the lower end of the mounting plate 5, the upper die 15 is arranged directly above the lower die 3, and a plurality of baffles 4 for protection are vertically arranged on the lower end of the mounting plate 5, and a plurality of the baffles 4 are arranged around the upper die 15, and a moving mechanism for telescoping the baffles 4 during stamping is provided on the mounting plate 5, and a cleaning mechanism for moving the flying stamping parts to the inside of the box body 1 is provided on the box body 1.

[0027] The moving mechanism includes a limit frame 11 corresponding to the baffle 4 one by one, the limit frame 11 is vertically installed on the mounting plate 5, and several limit frames 11 are arranged around the upper mold 15. The baffle 4 is vertically slidably connected to the inner wall of the limit frame 11, and an elastic telescopic rod 10 is vertically installed on the mounting plate 5 close to the limit frame 11. The output end of the elastic telescopic rod 10 faces downward, and a connecting rod 12 is installed at the output end of the elastic telescopic rod 10. The end of the connecting rod 12 away from the elastic telescopic rod 10 is installed at the lower end of the side wall of the baffle 4, and the lower end of the baffle 4 exceeds the lower end of the upper mold 15. The purpose is to make the baffle 4 contact the upper end of the box body 1 first, and then move out of the upper end of the box body 1. The limit frame 11 and the top of the bracket 7 are provided with a detection component for protecting the staff.

[0028] During stamping, the hydraulic telescopic rod 8 is started to extend, and the output end of the hydraulic telescopic rod 8 pushes the mounting plate 5 to move downward, and the mounting plate 5 drives the elastic telescopic rod 10, the baffle 4 and the upper mold 15 to move downward, and the cleaning plate 14 first contacts the upper end of the box body 1, and then the upper mold 15 continues to move downward and cooperates with the lower mold 3 to punch the workpiece. At the same time, the baffle 4 moves upward along the inner wall of the limit frame 11, and the baffle 4 drives the connecting rod 12 to move upward, and the connecting rod 12 compresses the elastic telescopic rod 10.

[0029] After the stamping is completed, the hydraulic telescopic rod 8 is started to retract, and the output end of the hydraulic telescopic rod 8 drives the mounting plate 5 to move upward, and the mounting plate 5 drives the elastic telescopic rod 10 and the upper mold 15 to move upward. Under the action of elastic force, the elastic telescopic rod 10 pushes the baffle 4 to continue to be pressed tightly against the upper end of the box body 1 until the upper mold 15 moves out of the distance of one end of the lower mold 3, and the elastic telescopic rod 10 drives the connecting rod 12 and the baffle 4 to move upward.

[0030] The detection component includes a laser ranging sensor 16 corresponding one to one with the baffle 4. The laser ranging sensor 16 is installed on the top of the bracket 7 directly above the baffle 4. A fixing block 9 for use with the laser ranging sensor 16 is installed on the upper end of the baffle 4 directly below the laser ranging sensor 16. A controller 6 for receiving the signal of the laser ranging sensor 16 and performing comparative analysis is installed on the bracket 7.

[0031] During stamping, the laser ranging sensor 16 detects the distance between the laser ranging sensor 16 and the fixed block 9 in real time, and transmits the detection data to the controller 6. Under normal circumstances, the distance data transmitted by several laser ranging sensors 16 are roughly the same. When the staff's hands and arms are under the upper mold 15, the staff's hands and arms push the baffle 4 on it upward, which causes the distance detected by the laser ranging sensor 16 at this position to be different from the distance detected at other positions. At this time, the controller 6 controls the hydraulic telescopic rod 8 to stop and lift it upward.

[0032] The cleaning mechanism includes an electric telescopic rod 13. An opening 2 is provided on one side of the upper end of the box body 1. The electric telescopic rod 13 is horizontally installed on the side of the upper end of the box body 1 away from the opening 2. The output end of the electric telescopic rod 13 faces the opening 2. A cleaning plate 14 is installed on the output end of the electric telescopic rod 13 for cleaning the upper end of the box body 1 and pushing the flying stamping parts into the inside of the opening 2. A screening component for separating the stamping parts and debris is provided inside the box body 1 below the opening 2.

[0033] The screening assembly includes a partition 17, which is vertically installed at the bottom of the box body 1. The partition 17 divides the box body 1 into a workpiece area and a debris area. The debris area is arranged directly below the opening 2. The upper end of the partition 17 is obliquely installed with a screen 18 for screening stamping parts and debris through a rubber block. The upper end of the screen 18 is obliquely installed on the inner wall of the box body 1 below the opening 2 through a rubber block. The lower end of the screen 18 is installed with a vibrator 19 for vibrating the screen 18.

[0034] After the stamping is completed, the electric telescopic rod 13 is started to extend, and the output end of the electric telescopic rod 13 pushes the cleaning plate 14 to move. The cleaning plate 14 pushes the debris and stamping parts at the upper end of the box 1 to the opening 2, and the electric telescopic rod 13 is retracted to reset the cleaning plate 14, and then falls through the opening 2 onto the screen 18. The vibrator 19 drives the screen 18 to vibrate, so that the debris passes through the leakage holes of the screen 18 and falls into the debris area, and the stamping parts fall into the workpiece area.

[0035] Working principle of automobile stamping die with protective structure:

[0036] During stamping, the hydraulic telescopic rod 8 is started to extend, and the output end of the hydraulic telescopic rod 8 pushes the mounting plate 5 to move downward, and the mounting plate 5 drives the elastic telescopic rod 10, the baffle 4 and the upper mold 15 to move downward, and the cleaning plate 14 first contacts the upper end of the box body 1, and then the upper mold 15 continues to move downward and cooperates with the lower mold 3 to punch the workpiece. At the same time, the baffle 4 moves upward along the inner wall of the limit frame 11, and the baffle 4 drives the connecting rod 12 to move upward, and the connecting rod 12 compresses the elastic telescopic rod 10.

[0037] After the stamping is completed, the hydraulic telescopic rod 8 is started to retract, and the output end of the hydraulic telescopic rod 8 drives the mounting plate 5 to move upward, and the mounting plate 5 drives the elastic telescopic rod 10 and the upper mold 15 to move upward. Under the action of elastic force, the elastic telescopic rod 10 pushes the baffle 4 to continue to be pressed tightly against the upper end of the box body 1 until the upper mold 15 moves out of the distance of one end of the lower mold 3, and the elastic telescopic rod 10 drives the connecting rod 12 and the baffle 4 to move upward.

[0038] During stamping, the laser ranging sensor 16 detects the distance between the laser ranging sensor 16 and the fixed block 9 in real time, and transmits the detection data to the controller 6. Under normal circumstances, the distance data transmitted by several laser ranging sensors 16 are roughly the same. When the staff's hands and arms are under the upper mold 15, the staff's hands and arms push the baffle 4 on it upward, which causes the distance detected by the laser ranging sensor 16 at this position to be different from the distance detected at other positions. At this time, the controller 6 controls the hydraulic telescopic rod 8 to stop and lift it upward.

[0039] After the stamping is completed, the electric telescopic rod 13 is started to extend, and the output end of the electric telescopic rod 13 pushes the cleaning plate 14 to move. The cleaning plate 14 pushes the debris and stamping parts at the upper end of the box 1 to the opening 2, and the electric telescopic rod 13 is retracted to reset the cleaning plate 14, and then falls through the opening 2 onto the screen 18. The vibrator 19 drives the screen 18 to vibrate, so that the debris passes through the leakage holes of the screen 18 and falls into the debris area, and the stamping parts fall into the workpiece area.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
