Technical Field
[0001] The utility model relates to the field of stamping dies, in particular to an automatic turning structure of a stamping die. Background Art
[0002] During stamping, the operator places the stamped part on the top of the lower die, and moves the upper die downward to stamp the stamped part, so that the shape of the stamped part changes and the stamping is completed. After the stamping is completed, the operator needs to remove the stamped part and place a new stamped part on the surface of the lower die to complete a single stamping.
[0003] At present, after the stamping of the cylindrical stamping parts is completed, since the stamping parts are sleeved on the surface of the lower die, and since the stamping parts generate heat due to friction and deformation during the stamping process, resulting in temperature rise, manual unloading may cause burns. The current automatic flipping mechanism needs to use a motor to drive the lower die to rotate, which increases the cost and energy consumption when the motor is additionally installed. In addition, it may be difficult to unload the materials due to the large friction between the stamping parts and the lower die. Therefore, an automatic flipping structure of the stamping die is proposed to address the above problems. Utility Model Content

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The following is combined with Figure 1 —4 further details of this application,
[0023] The present application embodiment discloses an automatic flipping structure of a stamping die. Figure 1 , an automatic flipping structure of a stamping die, comprising a processing table 1 and an upper die 2; the upper die 2 is located above the processing table 1 and is fixedly connected to a driving shaft at the top, a placement ring 3 is fixedly connected to the center of the top of the processing table 1, flipping components 4 are arranged on both the left and right sides of the top of the processing table 1, and an ejection component 5 is arranged on the surface of the flipping component 4;
[0024] Reference Figure 2 - Figure 3The flip assembly 4 includes a guide rail 41 fixedly connected to the left and right sides of the top of the processing table 1, a vertical groove 42 is opened on the inner wall of the guide rail 41, and a friction plate 43 is fixedly connected to the inner wall of the guide rail 41. An electric telescopic rod 44 is fixedly installed on the top of the processing table 1 located inside the guide rail 41. The top of the electric telescopic rod 44 is annular, and a flip member 45 is rotatably connected inside the annular structure. The top of the electric telescopic rod 44 is internally rotatably connected with the flip member 45. A friction ring 46 is fixedly installed on the surface of the flip member 45 close to the inside of the guide rail 41. One end of the flip member 45 close to the inside of the guide rail 41 is slidably connected to the inside of the vertical groove 42 to ensure that the flip member 45 moves vertically upward inside the guide rail 41. The friction ring 46 and the friction plate 43 is adapted to friction. When the friction ring 46 contacts the friction plate 43, the friction ring 46 will rotate under the action of friction force. The end of the friction ring 46 away from the guide rail 41 is fixedly connected to the lower mold 47. Grooves 48 are provided on the left and right sides of the top of the placement ring 3. Two guide rails 41 are symmetrically arranged on the left and right sides of the lower mold 47. There are two friction plates 43 and they are symmetrical about the axis center of the lower mold 47. The two groups of friction plates 43 drive the two friction rings 46 to rotate in the same reverse direction. The flip part 45 is composed of a cylinder at one end away from the lower mold 47 and a rectangular parallelepiped at the other end. The top of the flip part 45 is lower than the top of the placement ring 3 to avoid the upper mold 2 contacting the flip part 45 and affecting the stamping during the stamping process.
[0025] Reference Figure 4 The ejection assembly 5 includes a telescopic rod 51 fixedly installed inside the placement ring 3, a fixing ring 52 is fixedly installed on the top of the telescopic rod 51, and a winding wire 53 is wound around the surface of the fixing ring 52. A slide groove 54 is provided on the top of the friction ring 46 near the inside of the groove 48, and a spring 55 is fixedly installed on the inner wall of the slide groove 54 near the fixing ring 52. The end of the spring 55 near the lower mold 47 is fixedly connected to a lower trapezoidal block 56. The fixing ring 52 is arranged on the surface of the friction ring 46, and the friction ring 46 and the fixing ring 52 are rotatably connected. One end of the wire 53 away from the fixed ring 52 is fixedly connected to the surface of the lower trapezoidal block 56. When the flip member 45 rotates, it will rotate relative to the fixed ring 52. At this time, the winding wire 53 is tightened and pulls the lower trapezoidal block 56 to compress the spring 55 and move. The bottom wall of the slide groove 54 is fixedly installed with a telescopic rod 2 57, and the top of the telescopic rod 2 57 is fixedly connected with an upper trapezoidal block 58. The proximal ends of the lower trapezoidal block 56 and the upper trapezoidal block 58 are provided with inclined surfaces that are adapted for sliding connection. When the lower trapezoidal block 56 is pulled, the upper trapezoidal block 58 is pushed to move in the vertical direction through the inclined surface.
[0026] Working principle: After the operator places the stamping part on the top of the lower die 47, the operator operates the driving rod to drive the upper die 2 to move downward, and the stamping part on the surface of the lower die 47 is stamped by the upper die 2. After the stamping is completed, the operating driving rod is raised to separate from the stamping part;
[0027] After that, the operator drives the electric telescopic rod 44 to extend, and the electric telescopic rod 44 drives the flip member 45 to move upward. Since one end of the flip member 45 slides inside the vertical slot 42, the flip member 45 keeps moving upward horizontally. At this time, the flip member 45 drives the friction ring 46 and the lower mold 47 to move upward. When the lower mold 47 moves upward to the inside of the placement ring 3, the friction ring 46 contacts the friction plate 43. The friction ring 46 rotates under the friction force of the friction plate 43. Therefore, the friction ring 46 drives the fixedly connected flip member 45 to rotate inside the top of the electric telescopic rod 44. When the flip member 45 rotates, it drives the lower mold 47 to rotate, thereby completing the flipping of the lower mold 47.
[0028] During the process of the flip member 45 rising and flipping, the flip member 45 will pull the telescopic rod 1 51 to extend, and the flip member 45 will rotate inside the fixed ring 52. At this time, the winding wire 53 is wound on the surface of the fixed ring 52, and the winding wire 53 will pull the lower trapezoidal block 56 when it is wound, so that the lower trapezoidal block 56 compresses the spring 55 and slides inside the slide groove 54. During the movement of the lower trapezoidal block 56, the upper trapezoidal block 58 will be pushed through the inclined surface matched with the upper trapezoidal block 58, so that the upper trapezoidal block 58 is pushed and the telescopic rod 2 57 is stretched to move in the direction away from the slide groove 54. At this time, the upper trapezoidal block 58 will push the stamping part on the surface of the lower mold 47, and then the stamping part is pushed away from the lower mold 47 by the upper trapezoidal block 58.
[0029] The above shows and describes the basic principle, 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, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
