Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular to a component stamping die which is convenient for positioning. Background Art

[0002] The punching die is a common stamping die. The working process of the punching die is divided into the following parts according to the movement time sequence of the punch press. The punch press slider drives the upper die to move downward from the highest point in the open die state. At this time, the upper and lower dies are not in contact. When the upper punch plate contacts the punching part of the lower die, the upper punch plate stops moving, and the punch press slider continues to move downward. The upper die stripping spring begins to compress. The upper punch plate is pressed by the spring pressure to press the punching part. After a certain stroke, the punch mounted on the upper clamping plate contacts the punching part. The punch press slider continues to move downward. When it is close to the bottom dead point (closed die state), the punch completely enters the lower die hole to complete the punching. The punching waste falls from the lower template to the lower pad to the leakage hole of the lower die seat. Finally, the punch press slider drives the upper die to start rising.

[0003] When punching metal plates, some existing punching dies usually install a positioning device on the outside of the metal plates. The positioning device includes a positioning roller and a conveying roller. The metal plates are positioned and conveyed by the positioning roller and the conveying roller. However, after long-term use, some dies will have burrs on the lower end of the punched metal plates due to the blade not being sharp enough. Since the conveying roller will fit tightly with the upper and lower end surfaces of the metal plates, when there are burrs on the lower end of the punched metal plates, it will hinder the movement of the metal plates in the positioning device, thereby causing the metal plates to move poorly or get stuck. Summary of the invention

[0004] The object of the present invention is to provide a component stamping die capable of preventing a metal sheet from moving unsmoothly in a positioning device, so as to solve the problems raised in the above-mentioned background technology.

When the metal plate is inserted into the positioning structure, the upper rubber roller and the lower rubber roller in the positioning structure respectively press against the upper and lower end surfaces of the metal plate, and the ball presses against the two sides of the metal plate, which can effectively prevent the metal plate from being displaced when the stamping die punches the metal plate. When the metal plate moves in the positioning structure located on the right side of the lower die, the brush roller in the cleaning component can rotate under the drive of the first gear and the second gear, so as to sweep away impurities or iron filings on the upper surface of the metal plate, which is conducive to the smooth movement of the metal plate in the positioning structure while preventing impurities from affecting the punching accuracy.

[0014] 2. The present invention installs a grinding structure on the right side of the positioning structure located on the left side of the lower die. When the metal plate moves inside the positioning structure, the lower rubber roller located on the left side of the lower die will drive the connecting shaft to rotate through the synchronous wheel and the synchronous belt.

[0019] See also Figure 2 The positioning structure 5 includes a U-shaped support 501 installed on the upper end of the base plate 1, and two symmetrically distributed fixing plates 502 are installed on the outer side of the U-shaped support 501. Fixing screws penetrate the fixing plates 502, and the U-shaped support 501 is fixedly connected to the base plate 1 through the fixing plates 502 and the fixing screws. A lower rubber roller 503 and an upper rubber roller 504 are respectively installed on the inner side of the U-shaped support 501, and the upper rubber roller 504 is located on the upper side of the lower rubber roller 503.

[0020] See also Figure 6The lower rubber roller 503 and the upper rubber roller 504 are both rotatably connected to the U-shaped support 501 through bearings, and the connection between the lower rubber roller 503 and the upper rubber roller 504 and the metal plate 4 is a rolling connection. Two symmetrically distributed balls 505 are movably embedded on the inner wall of the U-shaped support 501 and located between the lower rubber roller 503 and the upper rubber roller 504, and the connection between the balls 505 and the metal plate 4 is a rolling connection.

[0021] See also Figure 6 and Figure 7 A cleaning component 8 for cleaning the upper end surface of the metal plate 4 is installed on the right side of the U-shaped support 501 on the right side of the lower mold 2. The cleaning component 8 has two support plates 801 that are symmetrically distributed and fixedly connected to the U-shaped support 501. A brush roller 802 is installed on the right side of the upper rubber roller 504, and the connection between the brush roller 802 and the support plate 801 is a rotating connection. A V-shaped hopper 803 is installed between the two support plates 801 and on the upper left side of the brush roller 802, and a plurality of groups of notched grooves 804 that are equidistantly distributed are opened on the right side plate of the V-shaped hopper 803. The plurality of groups of notched grooves 804 that are equidistantly distributed make the right side plate of the V-shaped hopper 803 look like a tooth comb.

[0022] See also Figure 7 Two symmetrically distributed T-shaped blocks 805 are fixedly installed on the outer side of the V-shaped hopper 803, a T-shaped slot 806 is opened on the upper end of the support plate 801, and the T-shaped block 805 is plugged and connected with the support plate 801 through the T-shaped slot 806, and the first gear 11 is fixedly installed at both ends of the rubber roller 504 on the upper right side of the lower mold 2, and the second gear 12 is fixedly installed at both ends of the brush roller 802 on the outer sides of the two support plates 801, and the connection between the first gear 11 and the second gear 12 is a meshing connection.

[0023] The working principle of the metal plate positioning is as follows: first, one end of the metal plate 4 is inserted between the upper rubber roller 504 and the lower rubber roller 503 located on the right side of the lower die 2. At this time, the two balls 505 movably embedded on the inner wall of the C-shaped support 501 will press against the left and right sides of the piece number plate 4. Since the upper and lower end surfaces of the metal plate 4 are tightly fitted with the upper rubber roller 504 and the lower rubber roller 503, the metal plate 4 is positioned by the positioning structure 5 located on the left and right sides of the lower die 2, which can effectively prevent the metal plate 4 from being punched by the stamping die. The plate 4 is located at a position that causes an error in the punching position. When the metal plate 4 moves in the positioning structure 5 located on the right side of the lower die, the metal plate 4 drives the upper rubber roller 504 and the lower rubber roller 503 to rotate. During the rotation, the upper rubber roller 504 drives the brush roller 802 to rotate through the first gear 11 and the second gear 12. The counterclockwise rotation of the brush roller 802 can sweep away impurities or metal debris on the upper surface of the metal plate 4, which is beneficial for the metal plate 4 to move smoothly in the positioning structure 5, and is also beneficial for preventing impurities and iron filings from affecting the punching accuracy. During the rotation process, the brush roller 802 contacts the tooth comb-shaped right side plate of the V-shaped hopper 803. The tooth comb-shaped right side plate of the V-shaped hopper 803 can comb off the impurities or iron filings attached to the brush roller 802, and the combed impurities and iron filings fall into the V-shaped hopper 803. When cleaning the impurities or iron filings in the V-shaped hopper 803, the T-shaped blocks 805 at both ends of the V-shaped hopper 803 can be directly pulled out from the T-shaped slots 806 on the support plate 801.

A synchronous belt 10 meshing with the synchronous wheel 9 is movably sleeved on the outer side.

[0026] The working principle for preventing the metal plate from moving smoothly in the positioning device is as follows: when the metal plate 4 moves in the positioning structure 5 located on the left side of the lower mold 2, the lower rubber roller 503 rotates under the drive of the metal plate 4, and the lower rubber roller 503 rotates through the synchronous wheel 9 and the synchronous belt 10 to drive the connecting shaft 607 to rotate, and the connecting shaft 607 rotates through the first bevel gear 604 and the second bevel gear 605 to drive the installation shaft 603 and the grinding disk 602 to rotate. Since the grinding disk 602 is movably fitted with the lower end surface of the metal plate 4, the grinding disk 602 can grind off the burrs on the punching edge of the lower end surface of the metal plate 4 during rotation, thereby helping to avoid the burrs hindering the metal plate 4 from moving between the upper rubber roller 504 and the lower rubber roller 503.
