Description

Technical Field

[0001] The utility model relates to the field of stamping and drawing, in particular to a stamping device. Background Art

[0002] Stamping and drawing is one of the most commonly used manufacturing processes in the automotive manufacturing industry. It is a processing method that can deform the sheet metal by applying external force to it through a press and a die. It is usually divided into six steps (blank, draw, trim, punch, flanging, shaping);

[0003] In the existing stamping and drawing, the pressing surface is too large, which is easy to cause defects such as cracking. Therefore, the sheet metal must be blanked through a separate blanking die before drawing. This situation will seriously affect the production efficiency. Since blanking and drawing are now divided into two processes, the automatic loading unit cannot be used for loading, and the sheet metal can only be transported and loaded manually. Manual handling usually requires multiple people to operate, which will directly increase labor costs, and at the same time increase the labor intensity, and cannot improve production efficiency.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0020] like Figure 1 , 3 As shown, a stamping device includes a stamping machine body 1, in which an upper die 2 and a lower die 4 for drawing a sheet material 7 are arranged inside the stamping machine body 1, an automatic feeding assembly is arranged on one side of the lower die 4, a blanking assembly is arranged on the upper die 2 and the lower die 4, and a material guiding assembly is arranged on the outside of the blanking assembly.

[0021] like Figure 1 , 3As shown, the automatic feeding assembly includes a storage box 11, and slide grooves 18 are respectively opened on both sides of the storage box 11, and slide rods 15 are supported and fixed in the corresponding slide grooves 18, and sliders 16 are slidably connected to the slide rods 15. Material receiving plates 17 are connected and fixed between the sliders 16, and two rollers 14 rotatably supported on the storage box 11 are arranged above the material receiving plates 17. One end of the roller 14 extends to the outside of the storage box 11 and is synchronously driven and connected with the output shaft of the driving motor 13.

[0022] like Figure 1 , 3 As shown, a spring 12 is sleeved on the slide bar 15 , one end of the spring 12 is connected and fixed to the bottom of the slide block 16 , and the other end of the spring 12 is connected and fixed to the bottom of the slide groove 18 .

[0023] like Figure 1 , 2 As shown, the blanking assembly includes an upper corner cutting knife 9 connected and fixed to the upper die 2, and a lower corner cutting knife is arranged on the lower die 4 and engages with the upper corner cutting knife 9 during drawing.

[0024] like Figure 1 As shown, the material guide assembly includes a blanking plate 8 which is arranged obliquely on the outer side of the lower cutter 10, and a plurality of rotatable universal balls are embedded on the upper part of the blanking plate 8.

[0025] like Figure 1 , 3 As shown, the blanking plate 8 extends to the outside of the lower mold 4, and a receiving groove 5 for receiving cutting waste is provided at its lower part.

[0026] like Figure 1 As shown, a guide plate 6 is provided at the lower part of the upper mold 2 .

[0027] like Figure 1 As shown, a blank holder 3 is provided between the upper die 2 and the lower die 4, and the blank holder 3 is fixed to the upper part of the lower die 4 by a spring.

[0028] The implementation principle of a punching device in the embodiment of the present application is:

[0029] Before the drawing process, a plurality of sheet materials 7 are placed on the receiving plate 17. After the sheet materials 7 are placed, the receiving plate 17 is pressed downward by the weight of the sheet materials 7. When the receiving plate 17 is pressed downward, the slider 16 moves downward. When the slider 16 moves downward, the spring 12 is pressed downward. At the same time, the spring 12 generates a rebound force to ensure that the sheet materials 7 are tightly fitted with the rotating roller 14. After the sheet materials 7 are placed, they are ready to start the drawing process.

[0030] When the drawing process is performed, the driving motor 13 is started to rotate, and the driving motor 13 rotates to drive the rotating roller 14 to rotate synchronously. The rotating roller 14 rotates and pushes the sheet material 7 to the upper part of the blank holder 3. When the sheet material 7 is completely pushed into the material storage box 11, the driving motor 13 is turned off, and the front end of the sheet material 7 is tightly fitted with the guide plate 6 on the upper die 2, thereby completing the loading work;

[0031] After the loading is completed, the punching machine body 1 starts to drive the upper die 2 to start pressing down. During the pressing process of the upper die 2, it will first fit with the blank holder 3. After the upper die 2 and the blank holder 3 fit together, the sheet 7 will be clamped. At the same time, the upper die 2 and the blank holder 3 continue to move downward. When they move to fit tightly with the lower die 4, the sheet 7 completes the stamping and forming work. When the upper die 2 and the blank holder 3 fit tightly with the lower die 4, the sheet 7 will be cut by the upper cutting knife 9 and the lower cutting knife 10 that mesh with each other at the part where blanking is required. After cutting, the excess waste will fall onto the blanking plate 8 and slide into the receiving trough 5. At the same time, the punching machine body 1 drives the upper die 2 to move in the reverse direction, and the sheet 7 that has been drawn is taken out from the blank holder 3, thereby completing the drawing work of a sheet 7.

[0032] The remaining sheet 7 continues to complete the drawing work according to the above steps;

[0033] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
