Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses stainless steel is bent and is not had scotch structure mould.
Referring to fig. 1 and 2, the stainless steel bending scratch-free structural die comprises an upper die holder 1 and a lower die holder 2 which are arranged oppositely, wherein a male die 3 and a guide rod 5 are fixedly installed on the upper die holder 1, and a female die 4 and a guide sleeve 6 are fixedly installed on the lower die holder 2. When the punch drives the upper die holder 1 to be close to or far away from the lower die holder 2, the guide rod 5 moves upwards or downwards in the guide sleeve 6, so that the moving stability of the upper die holder 1 is improved.
The female die 4 is provided with a first groove 7, and the middle part of the bottom of the first groove 7 is provided with a second groove 8. The first groove 7 and the second groove 8 both penetrate through the female die 4 along the length direction of the female die 4. The groove bottom of the first groove 7 is gradually lifted towards the two side walls by taking the central line as the lowest part. The second groove 8 is provided with a supporting block 9 in a penetrating mode, one side, close to the groove bottom of the second groove 8, of the supporting block 9 is fixedly provided with a supporting rod 10, and the supporting rod 10 is sleeved with a spring 11 in an empty mode. One end of the spring 11 is fixedly arranged on the supporting block 9, and the other end of the spring 11 is fixedly arranged on the bottom of the second groove 8.
Referring to fig. 2 and 3, both sides of the supporting block 9 are provided with bending blocks 12, one side of each bending block 12 close to the supporting block 9 is fixedly provided with an insertion block 13, and the supporting block 9 is provided with a slot 14 for the insertion of the insertion block 13. A gap for the bending block 12 to rotate is reserved between the inserting block 13 and the slot 14. The upper edge of the side of the bending block 12 close to the support block 9 is rotatably connected with a first rotating roller 15.
When the stainless steel is not bent, one side of the bending block 12 far away from the supporting block 9 abuts against the side wall of the first groove 7. When it is desired to bend the stainless steel, the stainless steel is placed on top of the two bending blocks 12. The punch drives the upper die holder 1 to move towards the inside of the second groove 8 through the supporting block 9 at one end of the lower die holder 2, so that the male die 3 is driven to extrude the stainless steel. The stainless steel is pressed to bend towards the space between the two bending blocks 12, and after the stainless steel is bent to a certain degree, the stainless steel is in contact with the supporting block 9.
The stainless steel continues to bend, thereby driving the supporting block 9 to move towards the inside of the second groove 8. The inserting block 13 arranged on the bending block 12 is inserted into the inserting groove 14 formed in the supporting block 9, so that when the supporting block 9 moves towards the inside of the second groove 8, the supporting block 9 drives the bending block 12 to turn over, and the bending block 12 extrudes the stainless steel. This is favorable to reducing the condition that the stainless steel resumes after the extrusion and appears, and first live-rollers 15 contacts with the stainless steel when the stainless steel is buckled simultaneously to change sliding friction into rolling friction, this is favorable to reducing the condition that the stainless steel is scratched and appears.
Referring to fig. 1 and 2, two sides of the male die 3 are both provided with pressing blocks 17, the pressing blocks 17 are fixedly provided with connecting blocks 18, and the pressing blocks 17 and the connecting blocks 18 are integrally formed. The male die 3 is provided with a placing groove 19 for the connecting block 18 to penetrate. Both ends of the male die 3 are fixedly provided with at least two connecting plates 20, and each connecting plate 20 is provided with a first bolt 21. The connecting plate 20 is fixedly connected with the male die 3 through a first bolt 21. In the embodiment of the present application, the male die 3 has two connecting plates 20 at both ends, and one connecting plate 20 corresponds to one pressing block 17. When two sides of the bent stainless steel need to be pressed, the connecting block 18 is inserted into the placing groove 19, then the connecting plate 20 is connected with the pressing block 17 through the first bolt 21, so that the pressing block 17 is installed on the male die 3, and at the moment, one side of the pressing block 17, which is far away from the lower die holder 2, abuts against the upper die holder 1. When the two sides of the bent stainless steel are not required to be pressed, the first bolt 21 is unscrewed, the connecting plate 20 is separated from the press block 17, and then the press block 17 is removed from the punch 3.
The lower edge of the side of the pressing block 17 far away from the male die 3 is rotatably connected with a second rotating roller 16. The pressing block 17 is obliquely arranged close to one side of the lower die base 2.
The implementation principle of the stainless steel bending scratch-free structure die in the embodiment of the application is as follows: when the two sides of the bent stainless steel are required to be pressed, the pressing blocks 17 are arranged on the two sides of the male die 3. The stainless steel is placed on the tops of the two bending blocks 12, the punch drives the upper die holder 1 to move towards the lower die holder 2, and the upper die holder 1 moves inside the guide sleeve 6 through the guide rod 5, so that the moving stability of the upper die holder 1 is improved.
After the male die 3 touches the stainless steel, the male die 3 continues to move to the space between the two bending blocks 12, so that the stainless steel is extruded, and meanwhile, the stainless steel tilts towards two sides. The stainless steel is tilted and then contacts with the first rotating roller 15, and sliding friction is replaced by rolling friction, which is beneficial to reducing the occurrence of scratching of the stainless steel.
After the stainless steel is bent to a certain extent, the stainless steel extrudes the support block 9. The supporting block 9 is squeezed to move towards the inside of the second groove 8, so that the first rotating rollers 15 on the two bending blocks reduce the stainless steel pressure towards the male die 3, and meanwhile, the two sides of the stainless steel are gradually flattened by the blocking of the pressing blocks 17. When the two sides of the stainless steel are flattened, the second rotating roller 16 is in contact with the stainless steel, and rolling friction replaces sliding friction, which is beneficial to reducing the occurrence of scratching of the stainless steel.
After the stainless steel is bent, the punch drives the upper die holder 1 to be away from the lower die holder 2, and the male die 3 is away from the female die 4, so that the stainless steel is bent.
When the two sides of the bent stainless steel are not required to be pressed, the pressing blocks 17 are taken down from the two sides of the male die 3. At this time, when the stainless steel is bent, both sides of the stainless steel are pressed by the bending blocks 12 to be tightly pressed against both sides of the male die 3.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
