Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal stamping, in particular to a sheet metal stamping processing device with automatic blanking. Background Art

[0002] Sheet metal stamping is a common metal forming process used to create various shapes from sheet metal. This process is widely used in a variety of industries, including automotive, aerospace, appliance manufacturing, and machinery. Sheet metal stamping involves a variety of different steps, including but not limited to shearing, bending, stretching, punching, and flanging. Stainless steel, due to its excellent corrosion resistance, aesthetics, and strength, is a commonly used material in sheet metal processing.

[0003] Currently, existing sheet metal stamping processing devices often eject the finished product from the mold during use. If the ejection point is improperly positioned, the ejection speed is inappropriate, or the ejection force is too large or too small, the sheet metal part will be subjected to excessive force in some parts during the ejection process, while other parts are subjected to less force, resulting in deformation and affecting subsequent use. Therefore, this application provides a sheet metal stamping processing device with automatic unloading to meet this demand. Utility Model Content

DETAILED DESCRIPTION

[0030] The following describes in detail a polymer material injection molding device provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative methods for implementing the invention in accordance with known techniques. Furthermore, the accompanying drawings are provided solely for the purpose of describing the embodiments in greater detail and are not intended to limit the present invention.

[0031] like Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, an embodiment of the present invention provides a sheet metal stamping processing device with automatic unloading, including: a workbench 1; a punching machine 4, arranged on the workbench 1; a placement groove 7, arranged in the workbench 1; a mold 8, arranged on the workbench 1 and located above the placement groove 7; a plurality of ejection holes 5, arranged in the mold 8; and the plurality of ejection holes 5 are distributed to the edge and center of the mold 8; a plurality of ejection parts 9, arranged in the placement groove 7 and corresponding to the ejection holes 5, the ejection part 9 including: a hydraulic cylinder 91, arranged in the placement groove 7, the hydraulic cylinder 91 is configured to extend and retract along the ejection hole 5; a first buffer pad 94, arranged on the output end of the hydraulic cylinder 91; a force sensor 92, arranged on the top of the first buffer pad 94, for measuring the force change during the ejection process; a second buffer pad 93, arranged on the top of the force sensor 92.

[0032] By starting ejection from the edge and moving toward the center, the risk of deformation of the sheet metal during the ejection process can be reduced. By setting a force sensor 92, the force applied to the sheet metal during the ejection process can be monitored in real time, and the monitored force value can be fed back to the controller 3 for real-time adjustment to ensure that the force is evenly distributed during the ejection process and to avoid deformation of the sheet metal due to excessive local force. The number of ejection holes 5 is at least three and above, which are respectively arranged at the edge and center of the mold 8. Case 1: at least one ejection hole 5 is provided at the center of the mold 8, and the two ejection holes 5 on the edge are symmetrically arranged along the center of the mold 8; Case 2: at least one ejection hole 5 is provided at the center of the mold 8. Hole 5, there are two groups of ejection holes 5 on the edge, and the two groups of ejection holes 5 are symmetrically arranged along the center of the mold 8, each group has at least two, and the two ejection holes 5 are respectively located at the edges of the mold 8; ensure that the material is evenly stressed during ejection to avoid deformation or damage caused by excessive or insufficient local pressure. The specific situation needs to be designed according to actual needs; if the number of ejection holes 5 is less than three, it will not be able to cover all key areas of the stamping part, resulting in excessive stress on some parts and insufficient stress on other parts, which will increase the risk of deformation of the workpiece and affect the quality and precision of the product. The ejection part 9 corresponds to the ejection hole 5, and the number of the ejection part 9 is the same as the ejection hole 5.

[0033] like Figure 8 As shown, it also includes: a plurality of buffer strips 96, which are arranged in the second buffer pad 93, and the plurality of buffer strips 96 are distributed in a circumferential manner and are located at the edge of the bottom of the inner cavity of the second buffer pad 93.

[0034] By providing the buffer strips 96, the ejection force can be dispersed to ensure that the ejection force is evenly distributed in the entire ejection area. The buffer strips 96 are wavy. When the buffer strips 96 are bent and deformed by the force, they contact the side walls of the second buffer pad 93, thereby transferring the force to the side walls and bottom wall respectively. The number of buffer strips 96 is at least two or more. The two buffer strips 96 can provide basic stability and balance, thereby dispersing the ejection force and ensuring that the ejection force is evenly distributed. If the number of buffer strips 96 is less than two, it is impossible to provide enough contact points on the bottom surface of the workpiece to evenly distribute the ejection force, which is likely to cause local stress concentration. Fewer than two buffer strips 96 cannot provide sufficient support, and the workpiece may tilt or rotate during the ejection process.

[0035] like Figure 8 As shown, it also includes: an air bag 95, which is arranged in the second buffer pad 93 and between the plurality of buffer strips 96. By providing the air bag 95, the impact force can be absorbed during the ejection process, reducing the impact between the hydraulic cylinder 91 and the sheet metal part during the ejection process.

[0036] like Figure 1As shown, it also includes: a collecting frame 6, which is detachably arranged on the workbench 1; an inclined groove is provided between the mold 8 and the collecting frame 6, and the highest point of the inclined groove is flush with the mold 8, and the lowest point of the inclined groove is flush with the collecting frame 6.

[0037] A collection frame 6 is provided to collect the finished sheet metal parts ejected from the mold 8, and the sheet metals are collected uniformly for subsequent use. At the same time, the collection frame 6 is detachably mounted on the workbench 1 by means of snaps or threads; by providing an inclined groove, it is ensured that the finished sheet metal parts can accurately slide into the collection frame 6, thereby realizing the automatic transfer of the finished products.

[0038] like Figure 1 As shown, the apparatus further includes a controller 3 disposed on the workbench 1. The controller 3 is used to coordinate the operation of the entire apparatus, including controlling the movement of the hydraulic cylinder 91, the start and stop of the fan 25, etc. The controller 3 can also adjust the ejection force and speed of the hydraulic cylinder 91 according to the feedback information of the force sensor 92, thereby ensuring a smooth ejection process, realizing automated control of the entire apparatus, and reducing manual intervention.

[0039] like Figure 1 、 Figure 4 and Figure 5 As shown, it also includes: a driving unit 2, which is arranged on the workbench 1, and the driving unit 2 includes: a support frame 21, which is arranged on the workbench 1; a fan 25, which is arranged in the support frame 21; a telescopic tube 22, which is connected to the output end of the fan 25; and a dust collection plate 23, which is slidably arranged on the workbench 1 and is located above the mold 8.

[0040] By setting up a support frame 21, an air inlet is provided on the support frame 21, which is convenient for external air to enter the support frame 21, and the air supply fan 25 sucks air. A filter is provided on the air inlet to prevent impurities from damaging the fan 25. A filter frame is set on the support frame 21, and the filter frame is connected to the telescopic tube 22. The output end of the fan 25 is connected to the filter frame to filter the absorbed waste chips to avoid discharging them. At the same time, the filter screen in the filter frame is detachable and easy to replace; by setting up the fan 25, the suction force generated can help remove the waste chips inside the mold 8, ensure that the mold 8 is clean, and reduce the impact of waste chips on the finished product; by setting up the telescopic tube 22, the length and direction can be adjusted as needed to ensure that the dust collection plate 23 will not be affected when it moves.

[0041] like Figure 1 and Figure 4 As shown, it also includes: a push plate 24, which is arranged on the dust collection plate 23; the side of the telescopic tube 22 away from the fan 25 is connected to the dust collection plate 23. By setting up the push plate 24, it can move with the movement of the dust collection plate 23, pushing the sheet metal, thereby completing automatic unloading.

[0042] like Figure 1 and Figure 6As shown, it also includes: a moving frame 26, which is arranged on the workbench 1 and close to the punching machine 4; a driving motor 27, which is arranged in the moving frame 26; a screw rod 28, which is rotatably arranged in the moving frame 26, and one side of the screw rod 28 is connected to the output end of the driving motor 27.

[0043] like Figure 1 and Figure 6 As shown, the mold 8 further includes a sliding block 29, which is threaded on the screw rod 28 and connected to the dust collection plate 23. The dust collection plate 23 is configured to move along the moving frame 26. By providing the sliding block 29, the sliding block 29 and the dust collection plate 23 are fixedly connected. When the sliding block 29 moves on the screw rod 28, the dust collection plate 23 is driven to move, thereby cleaning the interior of the mold 8.

[0044] The technical solution provided by the present invention is to place the sheet metal in the mold 8, use the controller 3 to start the punching machine 4 to perform stamping processing on the sheet metal, and after the processing is completed, use the controller 3 to start the hydraulic cylinder 91 to extend along the ejection hole 5 to start ejecting the sheet metal, so that the second buffer pad 93 contacts the sheet metal, and the edge hydraulic cylinder 91 is operated first to make the second buffer pad 93 contact the edge of the sheet metal, and slowly eject the edge of the sheet metal, and monitor the force change during the edge ejection process through the force sensor 92 to ensure that the edge ejection force is appropriate, and then operate the middle hydraulic cylinder 91 to make the second buffer pad 93 contact the middle of the sheet metal, and continue the ejection process, and continue to monitor the force change during the ejection process through the force sensor 92 to ensure that the center ejection force is appropriate, and then Then the sheet metal is completely ejected to ensure that the ejection process of the sheet metal gradually advances from the edge to the center; during the ejection process, the second buffer pad 93 and the sheet metal are deformed through the airbag 95 and the buffer strip 96 to reduce the impact force during the ejection process. After the sheet metal is completely ejected, the controller 3 is used to start the drive motor 27 and the fan 25. The drive motor 27 moves, driving the screw 28 to rotate, so that the sliding block 29 moves and the dust collection plate 23 moves. At the same time, the fan 25 runs, and dust is collected through the telescopic tube 22 and the dust collection plate 23. The sheet metal is pushed to move by the push plate 24, so that the sheet metal moves into the chute and then slides into the collection frame 6. In the process of pushing the sheet metal to move, the waste chips in the mold 8 are cleaned by the dust collection plate 23.

[0045] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
