Detailed Description
The technical scheme of the utility model is further explained in detail with the attached drawings as follows:
the utility model provides a covering negative angle side blow hole mechanism, including top board 6, terrace die 8, driving block 1 and sliding block 3, 6 fixed connection of top board is at 16 left side lower surfaces of upper die base, terrace die 8 is fixed and is located on the die holder 15 under the top board 6, driving block 1 inlays the right side of fixing at upper die base 16, sliding block 3 sets up the right side at lower die base 15, sliding block 3's left side is connected with side guide 4. The driving block 1 drives the sliding block 3 to move leftwards, and a return spring which drives the sliding block 3 to move rightwards is arranged on the sliding block 3.
The upper portion of the side pressing plate 4 is provided with an axial through hole, a movable working bolt 5 is matched with the through hole, the tail end of the working bolt 5 is fixedly connected with the sliding block 3, the head of the working bolt 5 is provided with a limiting nut, and the working bolt 5 can move in the through hole along the axial direction.
A through hole is formed in the middle of the side pressing plate 4, a punching male die 10 is arranged in the through hole, and one end of the punching male die 10 is fixedly connected with the sliding block 3.
The right side of the punching male die 8 is provided with a punching female die 9, the other end of the punching male die 10 corresponds to the punching female die 9 in position, and the two are matched in size.
A spring 12 is provided between the side platen 4 and the slide block 3.
The lower part of the side pressing plate 4 is provided with a guide assembly 11 for guiding the horizontal movement of the side pressing plate 4, the guide assembly 11 comprises a guide pillar and a guide sleeve, the guide pillar is arranged on the sliding block 3, the guide sleeve is arranged on the side pressing plate 4, the guide pillar is arranged in the guide sleeve, and the guide pillar and the guide sleeve are in sliding fit.
The bottom of the sliding block 3 is provided with a groove, a return spring is arranged in the groove, and the return spring is a nitrogen spring 13.
The surface of the male die 8 is provided with a layer of metal plate 7.
The utility model discloses there are two kinds of states, and initial condition is the open mode, as shown in figure 2. At this time, the side punching mechanism composed of the driving block 1 and the sliding block 3 is in a free state. When the utility model starts to work, the upper die base 16 starts to descend, in the process, the upper pressing plate 6 firstly contacts with the male die 8 and compresses the metal plate 7, and the wedge driving block 1 drives the wedge sliding block 3 to move horizontally through the self-lubricating wear-resisting plate 2; the side press plate 4 moves horizontally simultaneously with the slide wedge block 3 by the guide assembly 11, the slide block 3 is moved on and along the slide wedge block 3 by the V-shaped guide plate 14, and is previously contacted with the punch 8 and pressed against the side punch nearby profile by the urging of the elastic element spring 12, ensuring that the punch 10 corresponds to the punch die 9 and provides a pressing force during operation, in preparation for blanking, as shown in fig. 3. The upper die holder 16 continues to descend, and the sliding block 3 continues to be pushed to move, so that the sliding block compresses the spring 12, and further lateral pressure is applied to the side pressing plate 4, so that the punching male die 10 on the side pressing plate 4 starts to contact the plate until a punching state is reached, and the punching state is a closed working state at the moment. The punching male die 10 and the punching female die 9 are punched, and finally punching waste falls from the position of the punching female die 9.
After punching is completed, the upper die base 16 starts to move upwards, in the process, the upper pressing plate 6 is separated from the male die 8 firstly, the wedge driving block 1 does not act with the wedge sliding block 3, the wedge sliding block 3 returns under the action of the nitrogen spring 13, the nitrogen spring 13 provides a pressure source through compressed nitrogen, and compared with a conventional elastic element, the pressure source occupies a small space, has large initial pressure and is stable in pressure. The side pressure plate 4 and the punching male die 10 are driven to move horizontally together, and at the moment, the side pressure plate 4 has a certain pre-pressing amount under the action of the spring 12 and is still in an elastic pressing state with the male die 8; the mold continues to open, the side platen 6 begins to disengage from the punch 8, and finally reaches a reset state, returning to the open state of fig. 2.
In the Datong SV51 project, the punching mechanism is applied to a stamping process of a fender of an automobile panel. Because the product profile produces the punching press negative angle with the face of punching a hole, through using the utility model discloses a negative angle side punching mechanism satisfies forming process, improves the precision of punching a hole simultaneously, and present part has got into the volume production stage.
In the conventional side punching mechanism, a part profile is shielded above the side punching mechanism in the punching direction, so that the vertical movement of a pressure plate in the punching process can interfere with a product. Therefore, only some simpler products can be realized, and when a complex part has a negative angle in the stamping direction, the mechanism cannot realize the side punching process.
Because the die vertically moves up and down to complete the stamping action, when the metal plate moves along the stamping direction, the interference position of the metal plate and the male die is the position of the negative angle. The utility model discloses the panel beating is pushed down to the pressure flitch that does not need vertical motion, realizes presenting certain contained angle through slide wedge mechanism and realizes pressing the material to punch a hole with vertical direction to realize multi-angle negative angle side blow hole technology.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration only, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the claims and their equivalents.
