Technical Field

[0001] The utility model relates to the technical field of stamping and forming, in particular to a stamping and forming device for a protection cabin. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60-70% of the world's steel is sheet material, most of which is stamped into finished products. When processing the excavator engine protection cabin, the raw material sheet is placed on the stamping machine and then stamped.

[0003] With respect to the above-mentioned related technologies, the applicant believes that: when processing the excavator engine protection cabin, the steel plate to be processed is first placed on the processing table on the top of the die, and then the stamping machine on the top of the processing table punches the steel plate through the punch, so that the steel plate is forced into the die. After the punch and the die are combined, the excavator protection cabin is stamped into shape. After the punch and the die are separated, the formed protection cabin is inside the die, and the staff needs to take it out. It is heavy and very inconvenient to take it out, and there are certain safety hazards.

[0035] In the embodiment of the utility model, the purpose of this arrangement is that the arrangement of the stamping assembly 7 facilitates quick and easy demoulding when the engine protection compartment is subjected to stamping processing. The holder 713 installed on the bottom wall of the tooth plate 711 can prevent the rack 712 from detaching when it moves upward.

When the square rod 77 enters the inner wall of the positioning groove 710, the receiving shaft 79 can be prevented from rotating, thereby maintaining the overall stability of the stamping process.

[0036] Embodiment 2:

[0037] See also Figure 1-5 , this embodiment provides a technical solution based on the first embodiment: the bottom side walls of the U-shaped frame 71 are fixedly connected to the corresponding side walls of the mounting plate 4, the outer walls of the limiting plates 75 are slidably connected to the corresponding inner walls of the limiting grooves 72, the adjacent ends of the receiving shafts 79 are fixedly connected to the side walls of the concave mold 5, the bottom wall of the movable plate 76 is fixedly connected to the top wall of the punch 6, the outer walls of the square rods 77 are slidably connected to the corresponding inner walls of the positioning grooves 710, the top wall of the workbench 1 is fixedly connected to the receiving frame 2, the receiving shaft 79 is made of high-strength alloy steel, and the four corners of the bottom wall of the workbench 1 are fixedly connected to the supporting legs 3;

[0038] In the embodiment of the utility model, the purpose of this arrangement is that a soft pad is installed at the bottom of the inner wall of the receiving frame 2. When the processed protective cabin is demolded and falls into the receiving frame 2, it can avoid bumping and deformation, thereby preventing the finished product of the protective cabin from being affected. The receiving shaft 79 is made of high-strength alloy steel and has good support during stamping processing, thereby avoiding deformation.

[0039] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0040] During operation, the cylinder 74 is connected through an external controller, and then the movable end of the cylinder 74 is controlled by the external controller to work and push the movable plate 76 and the punch 6 to move downward slowly. At the same time, the movable plate 76 drives the limit plate 75 to slide in the inner wall of the corresponding limit groove 72 while moving downward, and the movable plate 76 drives the square rod 77 and the toothed plate 711 and the corresponding rack 712 to move downward, and at the same time, the gear 78 meshing with the rack 712 is driven to rotate, and the gear 78 drives the receiving shaft 79 and the die 5 to rotate 180 degrees while rotating. When the die 5 rotates 180 degrees, the rack 7 12 moves to the blank area of ​​the tooth plate 711, and the square rod 77 enters the inner wall of the positioning groove 710 when moving downward, thereby limiting the receiving shaft 79 to prevent rotation. As the cylinder 74 slowly pushes the moving plate 76 and the punch 6 to move downward, when there is a certain interval between the punch 6 and the die 5, the external controller controls the cylinder 74 to stop working, and places the sheet material that needs to be punched in the protection cabin at the top of the die 5. Then the external controller controls the cylinder 74 to continue working, so that the punch 6 starts to punch the sheet and enters the inner wall of the die 5 to start the mold closing. After the mold is closed, 711 and 713 are located in the inner wall of the through hole 73. After the stamping is completed, the movable end of the idle cylinder 74 begins to shrink through the external controller, and drives the movable plate 76 and the punch 6 to move upward to start demoulding, so that the punch 6 and the die 5 are separated, and the limiting plate 75 slides upward along the inner wall of the corresponding limiting groove 72, and the movable plate 76 drives the square rod 77 and the rack 712 to start moving upward. At the same time, the movable plate 76 drives the square rod 77 to gradually disengage from the inner wall of the positioning groove 710. After the disengagement, the blank area of ​​the tooth plate 711 moves to the area of ​​the rack 712. In the domain, the rack 712 is meshed with the gear 78, and synchronously drives the gear 78 and the receiving shaft 79 to rotate. When the receiving shaft 79 rotates, it drives the die 5 to flip 180 degrees, and the formed protective cabin is separated from the die 5 and falls into the receiving frame 2. Then, the continuous stamping of the protective cabin is started through the above-mentioned work process. When the die 5 rotates, there is enough space between it and the punch 6, and there will be no collision. In addition, the receiving shaft 79 is made of high-strength alloy steel. When the die 5 and the punch 6 are combined for stamping, the receiving shaft 79 will not be deformed, and the bearing force is sufficient.
