[0002] During the stamping production of alloy parts, there are multiple bending structures in the alloy parts.

DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0028] Example 1: A stamping machine for alloy parts processing with an automatic material taking mechanism, such as Figures 1-4As shown, it includes a workbench 11, a hydraulic lift 12, a lifting frame 13, a middle module 21, a top module 22, a side wedge-shaped slider 23, a side module 24, a spring cylinder 25, a wedge-shaped pressure block 26, a fixing frame 31, a stripping diagonal rod 32, a first torsion spring 33, a vertical rod 34, a hook 35 and a second torsion spring 36; three hydraulic lifts 12 are installed on the workbench 11; the lifting frame 13 is fixedly connected between the lifting components of the three hydraulic lifts 12; the middle module 21 is fixedly connected to the workbench 11; the top module 22 aligned with the middle module 21 is fixedly connected to the lifting frame 13; two side wedge-shaped sliders 23 symmetrical to each other with the middle module 21 as the center are slidably connected to the workbench 11; each of the two side wedge-shaped sliders 23 is fixedly connected to a side module 24; Two spring tubes 25 are connected; the elastic telescopic parts of the two spring tubes 25 are each fixed to a corresponding side wedge slider 23; two wedge-shaped pressure blocks 26 are fixed to the lifting frame 13, and the wedge-shaped pressure blocks 26 are aligned with the corresponding side wedge sliders 23 up and down; a through-groove structure 2101 running forward and backward is opened in the middle of the middle module 21; a fixed frame 31 is fixed to the workbench 11; a stripping diagonal rod 32 is rotatably connected to the fixed frame 31, and the stripping diagonal rod 32 is located in the through-groove structure 2101 of the middle module 21; two first torsion springs 33 are fixed together between the stripping diagonal rod 32 and the fixed frame 31; a vertical rod 34 is fixed to the lifting frame 13; the lower end of the vertical rod 34 is rotatably connected to a hook 35 that drives the stripping diagonal rod 32 to flip upward; two second torsion springs 36 are fixed together between the vertical rod 34 and the hook 35.

[0029] like Figure 1 As shown, three buffer limit blocks 14 are installed on the workbench 11. When the hydraulic lift 12 pulls the lifting frame 13 downward, the buffer limit blocks 14 can limit and buffer the descending action of the lifting frame 13; two electrically controlled lifting sliders 27 are slidably connected to the top module 22; and each of the two electrically controlled lifting sliders 27 is fixed with a downward pressure block 28.

[0030] During the stamping work of the alloy part processing stamping machine with an automatic material picking mechanism of the present invention, the staff first places the stamped alloy part 4 on the upper surface of the middle module 21, and then the staff controls the hydraulic lift 12 to drive the lifting frame 13 and the top module 22, wedge-shaped pressure block 26, electric-controlled lifting slider 27 and lower pressure block 28 connected thereto to move downward together. In the process of the downward-moving vertical rod 34 pushing the hook 35 downward to pass through the stripping oblique rod 32, the hook 35 will be affected by the main gear from the stripping oblique rod 32 and flipped upward. At the same time, the hook 35 drives the second torsion spring 36 to twist, so that the vertical rod 34 can push the flipped hook 35 to pass smoothly downward through the stripping oblique rod 32. After the hook 35 leaves the stripping oblique rod 32 downward, the twisted second torsion spring 36 drives the hook 35 to flip downward and reset.

[0031] Then, the two downward-moving lower pressing blocks 28 push the part of the stamped alloy part 4 located on the left side of the middle module 21 and the part of the stamped alloy part 4 located on the right side of the middle module 21 to bend downward, while the middle area of ​​the stamped alloy part 4 located on the upper side of the middle module 21 remains in close contact with the upper surface of the middle module 21, so that the left and right sides of the stamped alloy part 4 are bent downward to be between the middle module 21 and the side module 24 on the same side, and then the two electrically controlled lifting slides 27 drive the two lower pressing blocks 28 to rise respectively, so that The lower surfaces of the two lower pressing blocks 28 are flush with the lower surface of the top module 22, and then the two downward-moving wedge-shaped pressing blocks 26 push the two side wedge-shaped sliders 23 respectively to drive the side modules 24 connected thereto to move toward the middle module 21. At the same time, the side wedge-shaped sliders 23 drive the spring cylinder 25 to compress, and the side modules 24 press the downwardly bent part of the stamped alloy part 4 toward the middle module 21. At the same time, the downward-moving top module 22 presses the middle area of ​​the stamped alloy part 4 downward against the upper surface of the middle module 21. Figure 5 As shown, the middle module 21 , the top module 22 and the two side modules 24 jointly stamp the stamped alloy part 4 into an N-shaped structure, completing the stamping process of the stamped alloy part 4 .

[0032] Afterwards, the hydraulic lift 12 drives the lifting frame 13 and its connected top module 22, wedge-shaped pressure block 26, electric-controlled lifting slider 27 and lower pressure block 28 to move upward together to reset and leave the stamped alloy part 4. When the wedge-shaped pressure block 26 leaves the side wedge slider 23, the compressed spring tube 25 pushes the side wedge slider 23 to drive the side module 24 to move in the opposite direction to reset and leave the stamped alloy part 4. The stamped alloy part 4 in the shape of the letter N that has completed the stamping process is in a state of being stuck on the middle module 21. When the lifting frame 13 moves upward, it will pull the vertical rod 34 to drive the hook 35 to move upward. At the same time, the hook 35 pulls the stripping diagonal rod 32 to flip up, and at the same time, the stripping diagonal rod 32 drives the first A torsion spring 33 is twisted, and the upward-turned stripping diagonal rod 32 pushes the N-shaped stamped alloy part 4 stuck on the middle module 21 to flip upward, completing the automatic stripping and removal of the stamped alloy part 4. When the stripping diagonal rod 32 flips upward to the highest point, the stripping diagonal rod 32 will be limited by the fixing frame 31 and cannot continue to flip upward. At this time, the vertical rod 34 that continues to move upward will pull the hook 35 to move upward and pass through the stripping diagonal rod 32 in a flipped state according to the above steps. After the hook 35 leaves the stripping diagonal rod 32 upward, the twisted first torsion spring 33 will pull the stripping diagonal rod 32 to flip downward and reset, preparing for the placement and stamping processing of the next stamped alloy part 4.

[0033] Example 2: The difference between this example and Example 1 is that Figures 1-4As shown, in this embodiment, a groove structure 2102 is provided on the central module 21; a push plate 37 is provided in the groove structure 2102 of the middle module 21, and the upper surface of the push plate 37 is flush with the upper surface of the middle module 21; the push plate 37 is fixedly connected to the stripping diagonal rod 32; four electromagnets 211 are installed in the groove structure 2102 of the middle module 21; the push plate 37 is made of steel material; all electromagnets 211 are initially in close contact with the lower surface of the push plate 37; an insulating spacer 212 is provided between each electromagnet 211 and the middle module 21, so that the electromagnet 211 only generates electromagnetic attraction with the push plate 37 made of steel.

[0034] It should be noted that the stamped alloy member 4 in this embodiment is made of an iron material with magnetic conductivity.

[0035] like Figure 2 and Figure 3 As shown, the push plate 37 is initially located in the groove structure 2102 and forms a complete support module with the middle module 21. After the stamped alloy part 4 is placed between the middle module 21 and the top of the push plate 37, the electromagnet 211 generates an electromagnetic attraction to the stamped alloy part 4 through the push plate 37. At this time, the stamped alloy part 4 and the push plate 37 are both firmly magnetically attracted to the middle module 21.

[0036] It should be noted that during the stamping work on the stamped alloy part 4, when the lower pressure block 28 and the side module 24 stamp the stamped alloy part 4 on the push plate 37, the stamped alloy part 4 will not be displaced by the push from the lower pressure block 28 and the side module 24, thereby improving the precision of the stamping process on the stamped alloy part 4, allowing the stamped alloy part 4 to be stamped into an N shape, and the N-shaped stamped alloy part 4 is firmly stuck on the middle module 21.

[0037] Afterwards, when the lower pressing block 28 and the side module 24 leave the N-shaped stamped alloy part 4, the electromagnet 211 cuts off the electromagnetic attraction generated on the push plate 37 and the N-shaped stamped alloy part 4, and at the same time, the upward-moving hook 35 pushes the stripping inclined rod 32 to drive the push plate 37 to push the N-shaped stamped alloy part 4 on the middle module 21 upward. Figure 11As shown, since the upper surface area of ​​the push plate 37 is larger than the upper surface area of ​​the stripping diagonal rod 32, the contact area between the push plate 37 and the inner bottom of the N-shaped stamped alloy part 4 is larger than the contact area between the stripping diagonal rod 32 and the inner bottom of the N-shaped stamped alloy part 4. Therefore, the pressure applied by the push plate 37 to each area of ​​the N-shaped stamped alloy part 4 is smaller than the pressure applied to each area of ​​the N-shaped stamped alloy part 4 by only the stripping diagonal rod 32. Therefore, even if the thickness of the N-shaped stamped alloy part 4 is thin, the stamped alloy part 4 will not be deformed due to excessive pushing and extruding force when it is pushed up, thereby providing protection for the overall structure of the N-shaped stamped alloy part 4 obtained after stamping.

[0038] Example 3: The difference between this example and example 2 is that Figure 6-Figure 9 As shown, in this embodiment, a punching structure 2103 is provided on the left and right sides of the central module 21; two side modules 24 are provided with two punching strip structures 2401 on the side of the punching structure 2103 of the central module 21; the two punching structures 2103 of the central module 21 are each slidably connected to a wedge-shaped protrusion 213 in the middle, and the wedge-shaped protrusion 213 is located between the two punching strip structures 2401 of the corresponding side modules 24, and the wedge-shaped protrusion 213 in the punching structure 2103 of the central module 21 cooperates with the two punching strip structures 2401 of the side modules 24 to additionally punch out a bow-shaped groove structure on the n-shaped stamped alloy part 4. Structure 2102; two tension springs 214 are fixedly connected between the two wedge-shaped protrusions 213 and the middle module 21; a wedge-shaped control component is connected to the middle module 21 for controlling the wedge-shaped protrusions 213 to move inward and outward in the middle module 21; the electromagnet 211 is arranged on the upper side of the middle module 21; the push plate 37 is in close contact with the upper surface of the middle module 21 and the electromagnet 211 in the middle module 21; the wedge-shaped control component consists of a wedge-shaped double push rod 215 and an electrically controlled telescopic rod 216; the wedge-shaped double push rod 215 is slidably connected in the middle module 21; the electrically controlled telescopic rod 216 is installed on the middle module 21; the telescopic end of the electrically controlled telescopic rod 216 is fixedly connected to the wedge-shaped double push rod 215.

[0039] During the stamping work on the stamped alloy part 4, the electromagnet 211 generates an electromagnetic attraction to the stamped alloy part 4 through the push plate 37. When the lower pressing block 28 and the side module 24 are stamping the stamped alloy part 4 on the push plate 37, the electrically controlled telescopic rod 216 pulls the wedge-shaped double push rod 215 upward, and the wedge-shaped double push rod 215 pushes the wedge-shaped protrusion 213 to extend outward along the middle module 21. At the same time, the wedge-shaped protrusion 213 drives the tension spring 214 to stretch, so that the wedge-shaped protrusion 213 can cooperate with the two punching strip structures 2401 of the side module 24 to jointly punch out an additional bow-shaped groove structure 2102 on the N-shaped stamped alloy part 4. Figure 10 shown.

[0040] Afterwards, during the process of the lower pressing block 28 and the side module 24 leaving the N-shaped stamped alloy part 4, the electromagnet 211 disconnects the electromagnetic attraction generated on the push plate 37 and the N-shaped stamped alloy part 4, and at the same time, the electrically controlled telescopic rod 216 pushes the wedge-shaped double push rod 215 to move downward to leave the wedge-shaped protrusion 213. At the same time, the stretched tension spring 214 pulls the wedge-shaped protrusion 213 to retract into the interior of the middle module 21 to leave the groove structure 2102 punched out in the N-shaped stamped alloy part 4. Subsequently, the upward-moving hook 35 pushes the stripping diagonal rod 32 to drive the push plate 37 to push up the N-shaped stamped alloy part 4 that has completed the stamping process on the middle module 21. At this time, the groove structure 2102 in the N-shaped stamped alloy part 4 will not be blocked by the wedge-shaped protrusion 213 and can be smoothly flipped upward, allowing the N-shaped stamped alloy part 4 to smoothly leave the middle module 21 upward.
