Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts stamping, in particular to a stamping die which is easy to fix. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size.

[0003] At present, in the prior art, for example, a Chinese patent with announcement number CN218656453U discloses a stamping die for automobile parts. The device is installed with a limit mechanism, and the position of a strong spring and a telescopic rod is fixed by a groove. The strong spring exerts a pulling force on the anti-skid splint, so that the anti-skid splint is always downward, which is convenient for the subsequent clamping of the metal plate. The opening is convenient for the lifting and lowering of the block, and the block blocks the metal plate to prevent the displacement of the metal plate and the strong spring. The metal plate is used for subsequent stamping to form a component of the vehicle body. However, the device needs to pull the anti-skid splint in turn to limit and fix the metal parts. This operation is cumbersome and affects the stamping efficiency of the device. In view of this, we propose a stamping die that is easy to fix. Utility Model Content

[0014] (1) The stamping die that is easy to fix presses the metal part to make the sliding rod slide downward. When the sliding rod moves, the moving sleeve fixedly connected to the sliding rod moves synchronously. During this process, the sliding groove exerts a force on the rotating rod, so that the rotating rod rotates ninety degrees. At the same time, the pressing rod presses the metal part. When the metal part contacts the outer wall of the lower die, the clamping rod will bounce into the inner groove of the lower die under the elastic force of the spring four, thereby fixing the metal part.

[0015] (2) The stamping die that is easy to fix, when the output end of the hydraulic cylinder drives the template to press the metal part into the lower die, the sliding plate will drive the pressure rod 2 to move downward under the action of pressure, so that the pressure rod 2 applies a force to the push rod. During this process, the push rod moves toward the clamping rod and squeezes the clamping rod at the same time, so that the clamping rod slides toward the inside of the sliding rod, thereby releasing the limit of the moving rod 1. At this time, the moving rod 1 will drive the moving sleeve to move upward under the elastic force of the spring 2. During this process, the sliding groove will again apply a force to the rotating rod, so that the rotating rod returns to the initial position, thereby releasing the limit of the metal part.

[0028] In the embodiment of the utility model, in order to fix the metal part 5, specifically, the fixing device includes a rotating rod 11, the rotating rod 11 is penetrated by a pressure rod 112 and is slidably connected to the pressure rod 112, the outer wall of the pressure rod 112 is fixedly connected to one end of a spring 111, the other end of the spring 111 is fixedly connected to the inner wall of the rotating rod 11, the rotating rod 11 is rotatably connected to the lower mold 1, and the moving sleeve 12 is provided with a sliding groove 121, the sliding groove 121 is slidably connected to the rotating rod 11, and the moving sleeve 12 is provided with a sliding groove 121. The sliding groove 121 is slidably connected to the rotating rod 11, and the moving sleeve 12 is provided with a sliding groove 121. The movable sleeve 12 is fixedly connected with a sliding rod 13, and the sliding rod 13 is slidably connected to the inner wall of the lower mold 1. The outer wall of the sliding rod 13 is fixedly connected with a moving rod 15. The end of the sliding rod 13 away from the moving rod 15 is fixedly connected with a spring 2 14. The end of the spring 2 14 away from the sliding rod 13 is fixedly connected to the inner wall of the lower mold 1. The sliding rod 13 is slidably connected with a clamping rod 131. The outer wall of the clamping rod 131 is fixedly connected with a spring 4 132. The end of the spring 4 132 away from the clamping rod 131 is fixedly connected to the inner wall of the sliding rod 13.

[0029] like Figure 2 and Figure 4 As shown, the metal piece 5 is placed on the outer wall of the moving rod 15, and then the metal piece 5 is pressed. At this time, the moving rod 15 slides downward under the action of the force. When the moving rod 15 slides, the sliding rod 13 fixedly connected to the moving rod 15 moves synchronously, and the spring 2 14 is elastically deformed. When the sliding rod 13 moves, the moving sleeve 12 fixedly connected to the sliding rod 13 moves synchronously. When the moving sleeve 12 moves, the sliding groove 121 applies a force to the rotating rod 11, so that the rotating rod 11 rotates ninety degrees. When the rotating rod 11 During the rotation process, the pressure rod 112 will contact the metal part 5 and be squeezed by the metal part 5, causing the pressure rod 112 to slide and the spring 111 to elastically deform. It should be noted that when the moving rod 15 is in the raised state, the clamping rod 131 is completely inside the sliding rod 13, and the spring four 132 is in an elastic deformation state. When the moving rod 15 is flush with the lower mold 1, the clamping rod 131 will bounce into the inner groove of the lower mold 1 under the elastic force of the spring four 132, thereby fixing the moving rod 15.

The push rod 19 is slidably connected to the inner wall of the lower mold 1.

[0031] When the output end of the hydraulic cylinder 3 drives the template 4 to press the metal part 5 into the lower mold 1, the sliding plate 17 will drive the pressure rod 2 16 to move downward under the action of pressure, and the spring 3 18 will undergo elastic deformation, such as Figure 4 As shown, when the pressure rod 16 moves downward, the pressure rod 16 will apply a force to the push rod 19, so that the push rod 19 moves toward the clamping rod 131, and at the same time squeeze the clamping rod 131, so that the clamping rod 131 slides into the sliding rod 13. It should be noted that when the pressure rod 16 completely pushes the push rod 19 into the inner groove of the lower mold 1, the clamping rod 131 is completely pushed into the sliding rod 13, and the outer wall of the clamping rod 131 is flush with the outer wall of the standard sliding rod 13, thereby releasing the limit of the moving rod 15. At this time, the moving rod 15 will drive the moving sleeve 12 to move upward under the elastic force of the spring 2 14. At the same time, during this process, the sliding groove 121 will again apply a force to the rotating rod 11, so that the rotating rod 11 returns to its initial position, thereby releasing the limit of the metal part 5.

[0032] In the present invention, when in use, the metal piece 5 is placed on the outer wall of the moving rod 15, and then the metal piece 5 is pressed to make the sliding rod 13 slide downward. When the sliding rod 13 moves, the moving sleeve 12 fixedly connected to the sliding rod 13 moves synchronously. In this process, the sliding groove 121 applies a force to the rotating rod 11, so that the rotating rod 11 rotates ninety degrees to fix the metal piece 5. When the moving rod 15 is flush with the lower mold 1, the clamping rod 131 will bounce into the inner groove of the lower mold 1 under the elastic force of the spring four 132, so as to fix the moving rod 15. Then the hydraulic cylinder 3 is started. When the output end of the hydraulic cylinder 3 drives the mold The plate 4 presses the metal part 5 into the lower mold 1. At this time, the sliding plate 17 will drive the pressure rod 16 to move downward under the action of pressure, so that the pressure rod 16 applies a force to the push rod 19. During this process, the push rod 19 moves toward the clamping rod 131 and squeezes the clamping rod 131 at the same time, so that the clamping rod 131 slides into the inside of the sliding rod 13, thereby releasing the limit of the moving rod 15. At this time, the moving rod 15 will drive the moving sleeve 12 to move upward under the elastic force of the spring 2 14. At the same time, during this process, the sliding groove 121 will apply a force to the rotating rod 11 again, so that the rotating rod 11 returns to its initial position, thereby releasing the limit of the metal part 5.
