Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a side punching component and a die. Background Art

[0002] Punching holes in workpieces usually include straight punching holes and side punching holes. Straight punching holes are holes processed by applying force in the vertical direction of the press. However, in actual production, there are many cases where punching is required on an inclined surface. At this time, the hole direction of the punching hole will form a certain angle with the original punching direction. This punching hole is called a side punching hole. When processing side punching holes, an inclined wedge mechanism is required to change the direction of the punching force in the vertical direction to achieve punching processing on the inclined surface of the workpiece.

[0003] When using the current cam mechanism to process side holes, it is usually necessary to add at least two cams and corresponding slideways to guide the slider for stamping. This will result in a larger volume of the cam mechanism, which will take up a larger space, and the mold height and outer dimensions of the mold will need to be increased, increasing the mold development cost and mold storage space. Since the cam mechanism has high precision requirements and a complex structure, its procurement cost is also high, which increases the production cost of side punching processing. This problem needs to be solved urgently. Utility Model Content

[0027] Please refer to Figures 2 to 4 , the present utility model provides a side punching component 3, including a guide seat 4, a movable block 6, a punch 10, and a resilient member 8. The guide seat 4 is arranged on the blank holder 5, and the guide seat 4 has a first limiting structure for restricting the movement track of the movable block 6; the movable block 6 is arranged on the guide seat 4, and the movable block 6 can reciprocate along a first direction; the punch 10 is arranged on the movable block 6 along the first direction, and the punch 10 is used for punching the workpiece; the resilient member 8 and the punch 10 are arranged on the same side of the movable block 6, and the resilient member 8 is used to drive the movable block 6 to move along the first direction. By arranging the movable block 6 that can reciprocate along the first direction in the guide seat 4, when the side punching component 3 punches the workpiece, the guide seat 4 can restrict the movement track of the movable block 6 to ensure the punching effect. The structure of the side punching component 3 is simple, occupies less space than the inclined wedge structure, and has strong practicability. Since the side punching component 3 occupies less space, it can also be adapted to the situation where the distance between the front punching and the side punching is relatively close and the punching process needs to be carried out simultaneously, and has good industrial value and economic benefits.

[0028] Among them, the first limiting structure is a movable hole opened on the guide seat 4 along the first direction, and the movable block 6 is arranged in the movable hole. By arranging the movable block 6 in the movable hole, the movable block 6 can be better limited. In this embodiment, the cross-section of the fixed block is in a shape of a Chinese character "hui", and the cross-section of the movable block 6 is square. By setting both the fixed block and the movable block 6 to have a square outer contour, the complexity of processing and assembly can be simplified, and the manufacturing and production efficiency can be increased.

[0029] Specifically, a guide plate 11 is provided between the guide seat 4 and the movable block 6, and the guide plate 11 is provided on the guide seat 4. Since the movable block 6 slides on the guide seat 4, the surface contacted by the sliding block when sliding on the guide seat 4 is the sliding surface, and the sliding surface is very easy to wear during the sliding process of the sliding block. By providing the guide plate 11, the wear of the guide seat 4 during the sliding process of the sliding block can be reduced, the service life of the guide seat 4 can be extended, and the cost of repairing and replacing the guide seat 4 can be reduced. The guide plate 11 should be made of a smooth material that is conducive to the sliding of the movable block 6, and the selection of the material of the guide plate 11 can be adjusted according to the actual usage.

[0030] In detail, the side punch assembly 3 also includes a second limiting structure, the movable block 6 has a punching position, the direction of the line from the punching position to the initial position is the first direction, and the second limiting structure is used to prevent the movable block 6 from continuing to move after reaching the punching position. By setting the second limiting structure, the movable block 6 can be prevented from continuing to move after moving to the punching position and damaging the mold. Setting the second limiting structure can improve the stability of the side punch assembly 3 during operation and extend its service life.

[0031] In this embodiment, the limiting structure includes a limiting step surface provided on the movable block 6 and a clamping surface provided on the guide plate 11 and cooperating with the limiting step surface. When the movable block 6 moves to the punching position, the limiting step surface on the movable block 6 contacts the clamping surface to prevent the movable block 6 from continuing to move. The movable block 6 is limited by providing the limiting step surface and the clamping surface, which has a simple structure, is easy to process, has strong practicality, and has a good limiting effect.

[0032] Among them, a pad 13 is provided on the side of the movable block 6 away from the punch 10. Since the side of the movable block 6 away from the punch 10 needs to be connected to the driving member, the driving member drives the movable block 6 to move to achieve punching. When the punch 10 punches the workpiece, the movable block 6 needs to withstand a large impact force. In order to prevent the movable block 6 from transmitting the impact force received to the driving member when the punch 10 punches the workpiece, causing the driving member to be dented or deformed, the side punching assembly 3 is provided with a pad 13 on the movable block 6. Since the pad 13 can withstand most of the impact force, the service life of the driving member is increased and the maintenance frequency of the mold is reduced.

[0033] Among them, the side punching assembly 3 also includes a rebound piece 8, which is arranged on the movable block 6 along the first direction, and the rebound piece 8 is used to drive the movable block 6 away from the workpiece after punching. By setting the rebound piece 8, the punch 10 can automatically rebound when punching the workpiece, so that the punch 10 is separated from the punching, which is convenient for the side punching assembly 3 to punch the next workpiece. In this embodiment, the rebound piece 8 is a nitrogen spring. Nitrogen springs have the advantages of small size, large elasticity, and long life. They can save mold space and reduce the number of springs used in the mold and the number of maintenance times. The type of the rebound piece 8 can be adjusted according to the actual punching requirements.

[0034] See also Figure 1 The utility model provides a mold, including a presser 5, an upper die base 1, a lower die base 2 and the side punching assembly 3 as described above. A presser 5 is arranged between the upper die base 1 and the lower die base 2. The presser 5 has a press part and a mounting part arranged on the press part. The presser 5 is used to press the workpiece on the lower die base 2. The punch 10 in the side punching assembly 3 faces and passes through the press part along a first direction to punch the workpiece. The upper die base 1 has a pushing part that pushes the movable block 6 to move along the first direction. The side punching assembly 3 is installed on the presser 5. In the process of punching the workpiece, the movement trajectory of the movable block 6 can be constrained by the guide seat 4 fixed on the presser 5, and then the movement trajectory of the punch 10 can be constrained to ensure the punching effect of the mold on the workpiece. The space occupied by the side punching assembly 3 in the mold is small and has strong adaptability to different working conditions. In this embodiment, the pushing part is a boss arranged on the upper die base 1, and the boss is arranged corresponding to the movable block 6. The shape of the pusher can be adjusted according to actual production requirements.

[0035] Among them, the side punching assembly 3 is connected to the press 5 through a key 7, and a key slot 12 is provided on the side punching assembly 3 and the press 5 respectively corresponding to the key 7. Along the height direction of the key 7, the two ends of the key 7 are respectively accommodated and fixed in the key slot 12 of the side punching assembly 3 and the key slot 12 of the press 5. In this embodiment, the fixing assembly is a pin and a bolt, the pin is used for positioning, and the bolt is used for fixing. The side punching assembly 3 and the press 5 are fixed by means of the key 7 and the key slot 12, and the lateral force received by the side punching assembly 3 can be transmitted through the key 7, so as to avoid the connection failure between the side punching assembly 3 and the press 5, thereby reducing the maintenance and replacement cost of the mold. And the connection method of the key slot 12 and the key 7 is convenient for production and assembly.

[0036] In detail, the key 7 includes a first key arranged along the second direction and a second key arranged along the third direction, the second direction is perpendicular to the third direction, and the second direction and the third direction are perpendicular to the first direction. By arranging the first key and the second key, the key 7 can better transmit lateral forces in different directions, thereby enhancing the stability of the connection between the side punch assembly 3 and the press 5.

[0037] In this embodiment, a press insert 9 is provided at the position where the punch 10 passes through the press part, and a first placement groove is provided on the press part corresponding to the press insert 9. The press insert 9 is placed in the first placement groove and is integrated with the press part. The press insert 9 is connected to the press part by bolts. By providing the press insert 9, the punch 10 can be prevented from excessively wearing the press part, and the cost of overhauling and replacing parts of the press 5 can be reduced.

[0038] In this embodiment, a die sleeve 14 is provided at the position of the die hole of the lower die base 2, and a second placement groove is provided at the lower die base 2 corresponding to the die sleeve 14. The die sleeve 14 is accommodated in the second placement groove, and the die sleeve 14 and the lower die base 2 are embedded as a whole. The die sleeve 14 can be provided to prevent the punch 10 from excessively wearing the lower die base 2, and reduce the cost of repairing and replacing parts of the lower die base 2.

[0039] Usage process: When the workpiece is placed on the lower die base 2, the die presses the workpiece through the presser 5 to prevent the workpiece from moving during the punching process. When the presser 5 moves to the bottom dead center, the side punching assembly 3 drives the movable block 6 to move through the upper die base 1, and the movable block 6 drives the punch 10 to move to punch the workpiece. At this time, the punch 10 enters the die sleeve 14 of the lower die base 2. After punching, as the upper die base 1 and the lower die base 2 separate, the rebound member 8 drives the movable block 6 to return to the initial position before punching, so that the movable block 6 drives the punch 10 to leave the die sleeve 14.

[0040] In summary, by setting a movable block 6 that can reciprocate along the first direction in the guide seat 4, when the side punching assembly 3 punches the workpiece, the guide seat 4 can constrain the movement trajectory of the movable block 6 to ensure the effect of the side punching. The structure of the side punching assembly 3 is simple. Since the side punching assembly 3 does not need to be provided with multiple inclined wedges and corresponding slideways, the space occupied by the side punching assembly 3 is smaller than that of the inclined wedge structure, and it is highly practical. Since the side punching assembly 3 occupies a small space, it can also be used in situations where the distance between the front punching and the side punching is close and the punching process needs to be performed simultaneously, and it has good industrial value and economic benefits.
