Description

[0002] In mechanical processing, forgings are workpieces or blanks with specific shapes, sizes and properties obtained by applying pressure to metal blanks to cause them to undergo plastic deformation. During the forging process of aluminum alloy materials, thinner aluminum alloy raw materials are precisely formed in conjunction with stamping equipment and dies. Continuous stamping is a commonly used technology. Through the coordination of multi-station continuous dies and automated feeding systems, coils or strips are continuously fed on a single stamping device, and multiple stamping processes (such as blanking, punching, bending, drawing, shaping, etc.) are completed in sequence, ultimately producing finished products or high-precision semi-finished products in one go.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments. Example 1

[0035] Reference Figure 1 and Figure 2, which is the first embodiment of the present invention, provides a stamping and forming device for mechanical processing, and the stamping and forming device for mechanical processing includes a stamping component 1, a template component 2, a cleaning component 3 and a conveying component 4. Through the arrangement of the cleaning component 3 and the conveying component 4, it is possible to perform a blocking operation and actively perform exhaust treatment when the stamping is moving downward, and when the stamping is moved upward and reset, the negative pressure design is used in combination with the atmospheric pressure to actively push out the waste chips, and at the same time, the processing material can be fed without the need for additional feeding equipment.

[0036] Specifically, the stamping assembly 1 includes a base 11 , a receiving frame 12 is fixed inside the base 11 , an exhaust member 13 is provided on the receiving frame 12 , a hydraulic cylinder 14 is provided on the top of the base 11 , and a thin plate 15 is provided on the top of the receiving frame 12 .

[0037] The exhaust component 13 is provided to lead the gas in the storage frame 12 out in one direction during the exhaust operation, and at the same time, to prevent the gas from flowing in again during the negative pressure operation, which meets the overall operation requirements. Auxiliary air expansion processing can also be performed, which is beneficial to the discharge of heat generated by the stamping waste in the storage frame 12, thereby achieving the purpose of auxiliary cooling.

[0038] Specifically, the template assembly 2 is arranged on the base 11, and includes an upper mold 21 fixed to the output end of the hydraulic cylinder 14, a pressing piece 23 is provided at the bottom of the upper mold 21, a lower mold 22 is provided at the bottom of the pressing piece 23, and a positioning piece 24 is provided at the top of the lower mold 22.

[0039] The cooperation between the upper die 21 and the lower die 22 enables continuous stamping processing to be performed on the continuously fed thin plate 15 .

[0040] When the upper mold 21 moves downward, the pressing member 23 first contacts the positioning member 24 and the cleaning assembly 3 to complete the subsequent exhaust and positioning operations.

[0041] The positioning member 24 can be used to position and conduct the thin plate 15, thereby ensuring the movement stability of the thin plate 15 and facilitating good stamping processing of the thin plate 15.

[0042] Specifically, the cleaning assembly 3 is arranged on the lower mold 22, and includes a fixing frame 31 fixed to the bottom of the lower mold 22, a first sealing plate 32 is slidably connected to the fixing frame 31, a transmission member 33 is provided on the top of the lower mold 22, a horizontal bar 35 is provided on one side of the transmission member 33, and a second sealing plate 34 is slidably connected in the storage frame 12.

[0043] Specifically, the conveying assembly 4 is arranged on one side of the base 11, including a transmission member 41 located outside the thin plate 15, including an auxiliary frame 41-1 located outside the thin plate 15, an active roller 41-2 is rotatably connected to the auxiliary frame 41-1, and gears 41-21 are fixed at both ends of the active roller 41-2. A guide member 42 is provided at the bottom of the auxiliary frame 41-1, including a fixed plate 42-1 fixed to the bottom of the auxiliary frame 41-1, and a tooth plate 42-2 is provided outside the fixed plate 42-1.

[0044] The thin plate 15 can be positioned by the transmission member 41 to ensure smooth transmission of the thin plate 15, and the auxiliary frame 41-1 and the driven roller 41-3 are both designed with anti-slip surfaces, which effectively increases the contact friction with the thin plate 15, and then when the active roller 41-2 actively rotates, the thin plate 15 will move smoothly. Example 2

[0045] Reference Figures 2 to 13 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0046] Specifically, the exhaust component 13 includes an air pipe 13-1 fixed on the storage frame 12, an exhaust hole 13-11 is opened at one end of the air pipe 13-1, a movable rod 13-2 is rotatably connected at the center of one end of the air pipe 13-1, a turbine 13-3 is fixed at one end of the movable rod 13-2, and a fan blade 13-4 is fixed at the other end of the movable rod 13-2, and a one-way valve 13-6 is fixed in the air pipe 13-1.

[0047] The movable rod 13-2 is rotatably connected to the air delivery pipe 13-1 through a sealed bearing. This design can ensure the installation sealing of the movable rod 13-2 and prevent the entry of stamping debris.

[0048] When the gas flows through the gas pipe 13-1 and is discharged, the turbine 13-3 rotates naturally, thereby driving the fan blades 13-4 to rotate, so that the air in the storage frame 12 is in a flowing state, which is conducive to uniformly discharging the heat on the surface of the stamping debris in the storage frame 12.

[0049] The pressing member 23 includes a pressing frame 23-1 located at the bottom of the upper mold 21. Vertical rods 23-2 are fixed to the four corners of the top of the pressing frame 23-1 and are slidably connected to the upper mold 21. A first spring 23-3 is sleeved on the vertical rod 23-2. One end of the first spring 23-3 is fixed to the bottom of the upper mold 21, and the other end of the first spring 23-3 is fixed to the top of the pressing frame 23-1.

[0050] The positioning member 24 includes a positioning rod 24-1 that is slidably connected to the lower mold 22. A positioning ring groove 24-11 is provided at the top of the outer ring of the positioning rod 24-1. A second spring 24-2 is fixed to the bottom of the positioning rod 24-1. A mold hole 22-1 and a vertical groove 22-2 are respectively provided at the top of the lower mold 22. The other end of the second spring 24-2 is fixed to the inner wall of the vertical groove 22-2.

[0051] By setting the first sealing plate 32, the plurality of mold holes 22-1 can be sealed after the inward movement is completed, thereby preventing gas from being discharged outward through the mold holes 22-1.

[0052] The transmission member 33 includes a displacement rod 33-1 slidably connected to the lower mold 22, a storage cavity 33-11 is opened in the displacement rod 33-1, a slider 33-2 is slidably connected to the bottom of the storage cavity 33-11, one end of the horizontal bar 35 is fixed to the outer ring of the slider 33-2, and a fourth spring 33-4 is fixed to the top of the slider 33-2, and the other end of the fourth spring 33-4 is fixed to the inner wall of the storage cavity 33-11.

[0053] When the displacement rod 33-1 is pressed downward by the pressure frame 23-1, the slider 33-2 will move downward synchronously under the elastic support of the fourth spring 33-4, driving the cross bar 35 to move synchronously until the cross bar 35 completes the squeezing of the first sealing plate 32. At this time, the cross bar 35 will contact the second sealing plate 34 and cannot move further downward, while the displacement rod 33-1 can still move further downward, and under the connection of the connecting rod 34-1, continue to push the second sealing plate 34 to slide inward to exhaust.

[0054] A third spring 31-1 is sleeved on the fixing frame 31, one end of the third spring 31-1 is fixed to the fixing frame 31, and the other end of the third spring 31-1 is fixed to the first sealing plate 32. First inclined grooves 32-1 are provided on both sides of the top of the first sealing plate 32, and a protrusion 35-1 is fixed to the bottom of the horizontal bar 35 and is slidably connected to the first inclined groove 32-1.

[0055] The third spring 31 - 1 is provided to provide an elastic connection force for the first sealing plate 32 , and is stretched when the first sealing plate 32 moves inward, so that the first sealing plate 32 can automatically move outward and reset in the absence of external force.

[0056] The top of the first sealing plate 32 is slidably connected to the bottom of the lower mold 22 and sealed.

[0057] Through the cooperation between the first inclined groove 32 - 1 and the protruding head 35 - 1 , the protruding head 35 - 1 can press the first inclined groove 32 - 1 when it moves downward, so that the first sealing plate 32 is pressed and displaced inward.

[0058] One side of the second sealing plate 34 is rotatably connected to a connecting rod 34 - 1 , and the other end of the connecting rod 34 - 1 is rotatably connected to the bottom of the displacement rod 33 - 1 .

[0059] The connecting rod 34 - 1 is arranged so that when the displacement rod 33 - 1 gradually moves downward, the second sealing plate 34 can be linked to move inward, and when the displacement rod 33 - 1 gradually moves upward, the second sealing plate 34 can be reset outward.

[0060] A driven roller 41-3 is rotatably connected to the auxiliary frame 41-1, and a protective member 41-4 is provided outside the auxiliary frame 41-1, including a mounting frame 41-41 fixed on the auxiliary frame 41-1, a clamping sleeve 41-42 is slidably connected to the mounting frame 41-41, a second inclined groove 41-43 is provided on one side of the clamping sleeve 41-42, a fifth spring 41-44 is fixed to the top of the clamping sleeve 41-42, and the other end of the fifth spring 41-44 is fixed to the mounting frame 41-41.

[0061] The gear 41 - 21 is meshed with the tooth plate 42 - 2 , so that when the tooth plate 42 - 2 moves linearly, the gear 41 - 21 rotates to drive the thin plate 15 to feed.

[0062] By setting the second bevel groove 41-43, when the gear 41-21 rotates clockwise and contacts the second bevel groove 41-43, the sleeve 41-42 is squeezed upward and the fifth spring 41-44 is compressed; similarly, when the gear 41-21 rotates counterclockwise, the gear 41-21 directly contacts the sleeve 41-42. At this time, the gear 41-21 cannot rotate, thereby realizing one-way locking and preventing the thin plate 15 from retreating at will.

[0063] A guide groove 42-11 is provided on the fixing plate 42-1. A support rod 42-12 is fixed to one side of the fixing plate 42-1. The other end of the support rod 42-12 is fixed to the positioning rod 24-1. A guide block 42-21 is fixed to the tooth plate 42-2 and is slidably connected to the guide groove 42-11.

[0064] When the positioning rod 24-1 moves up and down, with the cooperation of the support rod 42-12, the auxiliary frame 41-1 and the fixed plate 42-1 will move up and down synchronously to maintain the thin plate 15 in a horizontal state at all times, which is conducive to the cooperation of the upper mold 21 and the lower mold 22 to perform continuous stamping processing on the thin plate 15.

[0065] The guide block 42-21 and the guide groove 42-11 are both T-shaped in cross-section. This design can achieve the effect of anti-slip protection to prevent the tooth plate 42-2 from moving arbitrarily and separating from the fixed plate 42-1. At the same time, under the guidance of the guide groove 42-11, the tooth plate 42-2 can move synchronously.

[0066] A connecting frame 42-3 is provided at the bottom of the tooth plate 42-2, one end of the connecting frame 42-3 is fixed on the second sealing plate 34, a sleeve 42-4 is fixed on the top of the connecting frame 42-3, a sliding rod 42-5 is slidably connected in the sleeve 42-4, a sixth spring 42-6 is fixed to the bottom end of the sliding rod 42-5, and the other end of the sixth spring 42-6 is fixed to the inner wall of the sleeve 42-4.

[0067] By setting the sleeve 42-4 and the slide rod 42-5, the tooth plate 42-2 can be maintained in a horizontal state at all times. When the guide block 42-21 is in a high position in the guide groove 42-11, the tooth plate 42-2 is engaged with the gear 41-21. At this time, the tooth plate 42-2 is displaced linearly, and the gear 41-21 will rotate clockwise; when the guide block 42-21 is in a low position in the guide groove 42-11, the tooth plate 42-2 is no longer engaged with the gear 41-21. At this time, the tooth plate 42-2 is displaced linearly, and the gear 41-21 is not affected.

[0068] During use, the thin plate 15 is placed in the positioning ring groove 24-11. When the control hydraulic cylinder 14 is extended to work, the upper mold 21 and the pressure piece 23 are pushed downward. The pressure piece 23 first contacts the displacement rod 33-1 and the positioning rod 24-1, and as the hydraulic cylinder 14 pushes further, the displacement rod 33-1 and the positioning rod 24-1 are pressed downward until the upper mold 21 cooperates with the lower mold 22 to stamp the thin plate 15. The waste chips generated by the stamping are temporarily retained in the die hole 22-1.

[0069] As the positioning rod 24-1 moves downward, in cooperation with the transmission member 41, the thin plate 15 can be stably moved downward to fit the top of the lower mold 22. At the same time, the displacement rod 33-1 moves downward. With the cooperation of the fourth spring 33-4 and the slider 33-2, the horizontal bar 35 moves downward, and the convex head 35-1 presses the first inclined groove 32-1, causing the first sealing plate 32 to move inward. The third spring 31-1 is stretched to seal the bottom of the mold hole 22-1, maintaining the storage frame 12 in a sealed state.

[0070] As the displacement rod 33-1 moves further downward, with the cooperation of the connecting rod 34-1, the two second sealing plates 34 slide inward at the same time, and the gas in the storage frame 12 is discharged through the exhaust part 13, and the fourth spring 33-4 is compressed. Under the connection of the connecting frame 42-3, the tooth plate 42-2 is pulled to move. With the cooperation of the guide block 42-21 and the guide groove 42-11, the movement stability of the tooth plate 42-2 is guaranteed. After the movement of the second sealing plate 34 is completed, with the cooperation of the guide block 42-21 and the guide groove 42-11, the tooth plate 42-2 is in a high position and meshes with the gear 41-21.

[0071] After the upper die 21 and the lower die 22 cooperate to complete a single punching of the thin plate 15, debris is retained in the die hole 22-1. At this time, the hydraulic cylinder 14 is controlled to contract. Under the elastic action of the third spring 31-1 and the fourth spring 33-4, the displacement rod 33-1 automatically moves upward to link the second sealing plate 34 to reset, so that the space in the storage frame 12 is increased. Since the exhaust member 13 is a one-way design, when the total amount of gas remains unchanged, the storage frame 12 is in a negative pressure state, and the negative pressure value is -0.05~-0.08MPa, ensuring that the waste chip discharge rate is ≥95%.

[0072] At the same time, the horizontal bar 35 will also move up and reset as the displacement rod 33-1 moves up, and the first sealing plate 32 will no longer block the die hole 22-1. At this time, under the action of atmospheric pressure, the waste chips can be pushed out through the die hole 22-1 into the storage frame 12, achieving the purpose of convenient material discharge and anti-blocking protection.

[0073] During the resetting and outward movement of the second sealing plate 34, the tooth plate 42-2 and the gear 41-21 cooperate to link the active roller 41-2 to rotate one circle, feeding the thin plate 15 a fixed distance. After the resetting of the second sealing plate 34 is completed, the tooth plate 42-2 returns to its initial state and no longer meshes with the gear 41-21.

[0074] In this cycle, the negative pressure discharge and active feeding operations can be completed during the stamping process when the hydraulic cylinder 14 drives the upper mold 21 to move up and down, achieving the purpose of anti-blocking protection and convenient feeding, without the need for additional equipment intervention, which is more in line with the needs of continuous stamping processing. Example 3

[0075] Reference Figures 4 to 13 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0076] Specifically, the thin plate 15 is leveled before processing to ensure the quality of subsequent aluminum alloy component processing.

[0077] Sealing plates are installed on both the base 11 and the storage frame 12 , which can be used by personnel to discharge the waste temporarily stored in the storage frame 12 when the base 11 and the storage frame 12 are disassembled.
