DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The embodiment of the present application provides an integrated device for blanking, stretching, punching and pouring, which can solve the technical problems in the traditional process in the prior art that the pouring of parts of specific shapes requires multiple sets of molds, resulting in high costs, cumbersome pouring workflow and low work efficiency.

[0028] Figure 1 is a schematic diagram of a structure of a device for feeding, stretching, punching and pouring salad provided in an embodiment of the present application, such as Figure 1 As shown, the integrated device for material blanking, stretching, punching and pouring in the present application includes a forming mechanism and a hole-forming mechanism. The forming mechanism is prefabricated in advance according to the shape of the part to be holed, and can be understood as a forming mold of the part to be holed, so as to perform the first step of stretching and forming on the material, while the hole-forming mechanism is used to punch and pour holes on the parts in succession while the forming mechanism is working.

[0029] Specifically, the forming mechanism includes a stretching punch 1 with a punching channel 101 longitudinally opened therein and a stretching die 2 located above the stretching punch 1 and staggered with the stretching punch 1, and first inner stripping plates 3 for receiving the punching pressure of the stretching die 2 and being able to be raised and lowered are provided on both sides of the stretching punch 1; the hole-forming mechanism includes a punch 4 located in the stretching die 2 and opposite to the punching channel 101, and a salad end 401 and a hole-forming end 402 integrally formed from top to bottom are provided at the bottom of the punch 4.

[0030] The stretching punch 1 is arranged above the stretching die 2. During the pre-bending forming work, the part to be holed is placed on the stretching punch 1, the stretching punch 1 remains stationary, and the stretching die 2 moves toward the direction of the stretching punch 1. The stretching punch 1 and the stretching die 2 are staggered with each other to apply two opposite forces to the body of the part to be holed, forcing the part to be holed to deform.

[0031] In the present application, the forming shape of the part to be holed is a "J" shape. In one embodiment of the present application, the stretching punch 1 is located at the center of the part to be holed, the two ends of the part to be holed are bending areas, and the stretching die 2 is located above the bending area. When the part to be holed is stretched, the stretching die 2 is squeezed downward and pushes the two ends of the part to be holed downward to deform.

[0032] The first inner stripping plate 3 is located on both sides of the stretching punch 1 and directly below the stretching die 2. During the stretching work, the part to be holed spans the upper surface of the stretching punch 1 and the first inner stripping plate 3, and then the stretching die 2 descends. The stretching die 2 and the first inner stripping plate 3 respectively clamp the upper and lower surfaces of the bending areas at both ends of the part to be holed, and drive the bending areas to deform.

[0033] A punching channel 101 is arranged on the stretching punch 1, and the punching channel 101 penetrates the stretching punch 1 longitudinally, and the punch 4 is longitudinally arranged in the stretching die 2, and the bottom of the punch 4 is always exposed outside the stretching die 2. The setting position of the punch 4 is opposite to the punching channel 101, and the punch 4 will descend together with the stretching punch 1. The bottom end of the punch 4 exposed outside the stretching die 2 performs pre-punching and emptying work on the surface of the part to be holed, and then the waste generated by the punching will directly fall through the punching channel 101.

[0034] Figure 4A schematic diagram of the punch structure in an integrated device structure for blanking, stretching, punching and pouring salad provided in an embodiment of the present application, wherein the punch 4 is mainly used to perform punching and pouring salad while stretching the part to be holed. Therefore, a salad end 401 and a hole-forming end 402 located at the bottom of the salad end 401 are arranged at the bottom of the punch 4, the hole-forming end 402 is cylindrical, the salad end 401 is in a flower pot shape that is larger at the top and smaller at the bottom, and the diameter of the hole-forming end 402 is equal to the minimum diameter at the bottom of the salad end 401. When the punch 4 descends to the upper surface of the part to be holed, the hole-forming end 402 first contacts the part to be holed to form a pre-punched hole on the part to be holed, and then the punch 4 continues to descend, and the salad end 401 begins to enter the pre-punched hole and squeezes the inside of the pre-punched hole to form a salad.

[0035] Furthermore, the forming mechanism also includes a fixed lower die base 5, and the stretching punch 1 is fixedly arranged on the lower die base 5. In the stamping field, a complete set of stamping devices includes an upper die base 6 and a lower die base 5. The upper die base 6 is usually made of cast iron, cast steel or aluminum alloy, and is mainly used to connect the template and the top of the mold to ensure the stability and accuracy of the mold. At the same time, the upper die base 6 is the power end, which is used to drive the stretching die 2 and the punch 4 on the stretching die 2 to move up and down, and the lower die base 5 is the load-bearing component of the overall structure. The material is usually made of high-hardness and high-strength alloy steel. The upper die base 6 and the lower die base 5 are commonly used components in the field of stamping technology, and the upper die base 6 and the lower die base 5 include multiple other components, which have no special connection with the technical solution in the present application. They are collectively referred to as the upper die base 6 and the lower die base 5, and the specific components will not be repeated one by one.

[0036] Furthermore, the punching channel 101 longitudinally penetrates the stretching punch 1 and the lower die seat 5. The punching channel 101 is not only used to avoid and receive the salad end 401 and the hole forming end 402 of the punch 4 for punching and pouring, but also used to flow out the waste generated when the parts are holed. The waste can directly fall out of the stamping die through the punching channel 101, which is convenient for unified recycling and processing later.

[0037] Furthermore, the stretching die 2 includes a die body 201 and a recessed area 202 arranged at the bottom center of the die body. The shape of the recessed area 202 is the same as the top shape of the stretching punch 1. In the present application, the recessed area 202 is an avoidance area of ​​the stretching punch 1. When the material is formed, the recessed area 202 and the stretching punch 1 are interlocked and the two clamp the upper and lower surfaces of the central area of ​​the part to be holed, preventing the part to be holed from being displaced under the pressure of the stretching die 2, thereby facilitating the punch 4 to perform punching.

[0038] Furthermore, Figure 3A schematic diagram of the structure of a stretching punch 1 and a first inner stripping plate 3 in an integrated device structure for blanking, stretching, punching and salad pouring provided in an embodiment of the present application, a first reset spring 3 and a first high-order screw 302 are provided at the bottom of the first inner stripping plate 3, two ends of the first reset spring 3 are respectively connected to the top of the lower die base 5 and the bottom of the first inner stripping plate 3, one end of the first high-order screw 302 is connected to the first inner stripping plate 3, and the other end of the first high-order screw 302 passes through the lower die base 5 and can be longitudinally translated in the lower die base 5.

[0039] The first return spring 3 is mainly used for the return work of the first inner stripping plate 3, and the first high-order screw 302 can ensure the connection stability between the first inner stripping plate 3 and the lower die seat 5. Specifically, the first inner stripping plate 3 receives the downward pressure of the stretching die 2 and descends together with the stretching die 2, and the first return spring 3 is in an extruded state. After the salad pouring work is completed, the stretching die 2 rises, and the first return spring 3 pushes the first inner stripping plate 3 to return to its original position, while the first high-order screw 302 moves longitudinally in the lower die seat 5 with the displacement of the first inner stripping plate 3, which can play a traction role on the movement of the first inner stripping plate 3.

[0040] The first inner release plate 3 is located on both sides of the stretching die 2. Therefore, in the embodiment of the present application, the first inner release plate 3 can be two separate bodies, and the two first inner release plates 3 move independently. The first inner release plate 3 can also be an integral body avoiding the stretching die 2. There is no specific restriction in the present application, but it should be noted that when the first inner release plate 3 is two separate independent individuals, a first reset spring 3 and a first high-order screw 302 are arranged at the bottom of each first inner release plate 3. When the first inner release plate 3 is an integral body, it is only necessary to arrange the first reset spring 3 at the bottom of the first inner release plate 3 on one side of the stretching die 2, and to arrange the first high-order screw 302 at the bottom of the first inner release plate 3 on the other side of the stretching die 2.

[0041] Furthermore, Figure 2 A schematic diagram of the structure of a stretching die 2 in an integrated device structure for blanking, stretching, punching and salad pouring provided in an embodiment of the present application, wherein the top of the stretching die 2 and the top of the punch 4 are both connected to the bottom of the upper die base 6, a second inner release plate 7 is arranged in the recessed area 202, a punch hole 4 for the punch 4 to pass through is longitudinally opened at the center of the second inner release plate 7, a second return spring 702 is arranged on the top of the second inner release plate 7, and the two ends of the second return spring 702 are respectively connected to the top of the second inner release plate 7 and the bottom of the upper die base 6.

[0042] The second inner stripping plate 7 is arranged in the recessed area 202, and in the state of being stationary and without the action of external force, the bottom of the second inner stripping plate 7 is exposed outside the recessed module body 201, occupying a certain space in the recessed area 202, and the punch 4 passes through the second inner stripping plate 7. The second inner stripping plate 7 is arranged to be retractable. In the state of being stationary and without the action of external force, the bottom of the hole forming end 402 of the punch 4 is level with the bottom of the second inner stripping plate 7, and the stretching die 2 drives the second inner stripping plate 7 and the punch 4 to descend together. When the part is bent, the second inner stripping plate 7 and the hole forming end 402 of the punch 4 first contact the surface of the part, and the second inner stripping plate 7 is blocked by the stretching punch 1 and cannot continue to descend. At this time, as the stretching die 2 continues to descend, the second return spring 702 begins to be squeezed, and a relative displacement occurs between the second inner stripping plate 7 and the punch 4. The hole forming end 402 and the salad end 401 of the punch 4 begin to gradually expose the second inner stripping plate 7 and successively pass through the part to be holed and enter the punching channel 101. After the salad pouring work is completed, the drawing die 2 rises, and the second return spring 702 pushes the second inner stripping plate 7 back to its original position.

[0043] Figure 5 A schematic diagram of the working state of a material blanking, stretching, punching and salad pouring integrated device provided in an embodiment of the present application, the working mechanism of the material blanking, stretching, punching and salad pouring integrated device in the present application is as follows: first, the part is placed above the stretching punch 1 and the first inner stripping plate 3, and then the upper die seat 6 is started to drive the stretching die 2 and the punch 4 to descend, and the punch 4 and the second inner stripping plate 7 first contact the upper surface of the hole forming position of the part to be holed, and the second inner stripping plate 7 no longer descends and clamps the part to be holed up and down with the stretching punch 1, and then, the stretching die 2 drives the punch 4 to continue to move downward, and while the part to be holed is deformed, the hole forming end 402 and the salad end 401 of the punch 4 begin to gradually extend and successively pass through the part into the punching channel 101, and finally the stamping waste flows out through the punching channel 101.

[0044] The integrated device for blanking, stretching, punching and pouring in the present application can complete the three working steps of part stretching, hole forming and pouring in the same mold simultaneously by setting a forming mechanism and a hole forming mechanism. It can not only greatly reduce the demand for mold purchase and reduce the production investment of the enterprise, but also reduce the process flow and improve work efficiency.
