Description

Technical Field

[0001] The invention relates to the technical field of sheet metal stamping, and in particular to a sheet metal progressive stamping die. Background Art

[0002] Sheet metal, a processing technology, lacks a comprehensive definition. According to a definition published in a foreign professional journal, sheet metal is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combining, folding, riveting, splicing, and forming (such as automobile bodies). Its most notable feature is the consistent thickness of each part. Sheet metal stamping, also known as "stamping," is a process that uses a large amount of force to change the shape of a flat metal sheet. This process may also involve punching holes in the metal. Sheet metal stamping is a very common process.

[0003] The existing sheet metal stamping mechanism model is relatively simple. When the workpiece is continuously operated, except for the pressed parts, the other parts have different shapes, which are not easy to stack in one place for collection, and will also cause losses during transportation.

[0016] The present invention provides a progressive stamping die for sheet metal parts. It has the following beneficial effects:

[0017] 1. The sheet metal progressive stamping die has three mechanisms inside the sheet metal stamping equipment, namely a blanking mechanism, a limiting mechanism and a management mechanism. The equipment adds deformation and stamping structures for the workpiece, and the two are used in conjunction to accelerate the processing efficiency of sheet metal parts. In addition, the interior is also provided with a blanking and a neat structure for sheet metal parts, which has a fast blanking speed and greatly improves the processing efficiency of the mechanism.

[0018] 2. The sheet metal progressive stamping die, through the use of a management mechanism, is equipped with a structure for arranging the sheet metal parts inside the management mechanism. The arranging structure is double-layered, and with the fan blades rotating in opposite directions, it can prevent the workpiece from falling into the bottom and gaps of the structure to avoid blockage. The workpiece enters the double-layer structure and is pressed downward, and the sheet metal part slides down to the lowest point to be fixed.

[0019] 3. The sheet metal progressive stamping die uses a limit mechanism, in which a touch plate and a spring group are arranged inside the limit mechanism. The limit mechanism is engaged with the edge of the workpiece and then pulled upward to ensure that the edge height of the workpiece remains consistent. The upward edge of the workpiece reduces the direct contact area with the outside world and reduces wear.

[0020] 4. The sheet metal progressive stamping die uses a blanking mechanism, in which an elastic structure is provided inside the blanking mechanism to cooperate with a rotating structure, thereby ensuring that the external expansion tube can still return to its original position after rotating upward or downward, and the use of this structure increases the range of motion of the external expansion tube.

[0037] The unloading mechanism (3) comprises a side tube (301), the outer surface of the side tube (301) is fixedly connected to the top of the side platform (2), the inner surface of the side tube (301) is provided with a special-shaped groove, and the inner surface of the side tube (301) is slidably connected to a control shaft (302).

[0038] The outer surface of the control shaft (302) is rotatably connected to a steering gear (303), the top of the steering gear (303) is fixedly connected to a support plate (304), and the top of the support plate (304) is rotatably connected to a threaded rod (305).

[0039] The outer surface of the threaded rod (305) is connected to the folding rod (306) in a transmission manner. The outer surface of the folding rod (306) is connected to the back plate (307) in a rotational manner through a bearing. The bottom of the back plate (307) is fixedly connected to the telescopic rod (308).

[0040] The left side of the telescopic rod (307) is fixedly connected to the outer surface of the support plate (304), the left side of the back plate (307) is fixedly connected to the elastic sleeve (309), and the inner surface of the elastic sleeve (309) is fixedly connected to the sliding rod (310).

[0042] The outer surface of the fixed plate (311) is fixedly connected to an outward expansion tube (313), a damping shaft (314) is fixedly connected between the top of the outward expansion tube (313) and the bottom of the slide bar (310), and anti-slip strips are evenly distributed on the inner surface of the gripping plate (312). The use of this structure increases the range of motion of the outward expansion tube (311).

[0043] During use, when pressurizing the sheet metal, the sheet metal to be processed is transferred to the middle position of the processing through the transmission table 14 below, and the hydraulic rod 4 is driven to start working, driving the top cover 5 to move up and down repeatedly. When the multiple stamping parts 9 above move downward, their outer surface passes through the outer surface of the workpiece, and as they move upward, they also drive the workpiece to move upward. At this time, the bogie 17 is rotated to move forward along the side groove 16 until the two limit platforms 18 are connected to each other to form a plane. The gap between the stamping part 9 above and the workpiece and the clamping column 1 is left. 9 contacts each other, leaving the workpiece on the outer surface of the limit table 18. After the punching work is completed, the sinking table 6 slides forward, driving the rear pressing shaft 21 to move downward to press the outside of the workpiece. When pressing downward, the workpieces on both sides of the pressing shaft 21 are tilted upward, and the edge of the workpiece is stuck between the touch plate 704. The outside of the slide plate 703 has an anti-slip effect. After being stuck, as the pressing structure moves upward, it gradually pulls the edge of the workpiece. The workpiece can maintain a straight arc except for the pressing part. After the workpiece is pressed, the threaded rod 305 is driven to rotate The outer portion of the threaded rod 305 has a spiral structure that is connected to the folding rod 306. As the threaded rod 305 rotates, the folding rod 306 gradually contracts, and the telescopic rod 308 below moves inward at the same time. The distance between the entire back plate 307 and the support plate 304 is reduced, and the back plate 307 moves forward and gradually approaches the support plate 304. The internal sliding rod 310 is subjected to the elastic force of the elastic sleeve 309 and continues to move forward to the outside of the workpiece until it moves to the vicinity of the pressing shaft 21. At this time, the outer expansion tube 313 is pulled upward to fix the plate 311 rotates upward to drive the grab plate 312 to move to the bottom of the workpiece, and then continues to push forward, pushing the pressed and punched workpieces one by one into the inside of the side box 10, and rotating the drive fan 1105. Since the fan blades rotate upward, the workpiece pushed to the side box 10 is prevented from sliding to the bottom of the side box 10. The workpiece contacts the shift plate 1103 and encounters resistance, and stays under the spring plate 1108. Then the spring plate 1108 slides downward to fix the workpiece. As the workpieces slide one by one to the top of the shift plate 1103, they are stacked in one place.

[0044] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
