[0025] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0026] like Figures 1 to 3 As shown, the present application provides a blanking device, wherein the blanking device includes a frame 1, a blanking component 2 and an impact component 3.

[0027] The frame 1 is used to provide a mounting base for the punching assembly 2 and the impact assembly 3. The frame 1 can be a three-dimensional frame structure formed by combining a plurality of vertical rods arranged longitudinally and a plurality of horizontally arranged cross rods. Optionally, a plate structure or a beam structure can be connected between the frame structures to improve the structural strength of the frame 1.

[0028] A top plate is provided on the top of the frame 1 , and an upper surface of the top plate forms a mounting plane 11 , on which the punching assembly 2 and the impact assembly 3 are both mounted.

[0029] Optionally, rollers are installed at the bottom of the frame 1 to facilitate the movement of the punching device.

[0030] Optionally, the roller has a locking function, in which the roller cannot be rolled in a locked state, and in an unlocked state the roller can be rolled.

[0031] The punching assembly 2 includes a first die 21, a second die 22 and a bracket 23. The bracket 23 is used to realize the relative arrangement of the first die 21 and the second die 22. The first die 21 and the second die 22 can cooperate to punch the plate 4 to obtain a punched part.

[0032] Specifically, the first mold 21 and the bracket 23 are both installed on the mounting plane 11. The bracket 23 includes a limit plate 231. The limit plate 231 is parallel to the mounting plane 11, and along a direction perpendicular to the mounting plane 11, the limit plate 231 is arranged opposite to the first mold 21, that is, along the direction perpendicular to the mounting plane 11, the projection of the first mold 21 at least partially overlaps with the projection of the limit plate 231.

[0033] The limiting plate 231 is provided with a through hole 2311, and the through direction of the through hole 2311 is perpendicular to the installation plane 11; a part of the impact component 3 passes through the through hole 2311 and can reciprocate along the through direction of the through hole 2311, and the second die 22 is connected to the end of the impact component 3 facing the installation plane 11. When performing the blanking process, the sheet 4 is placed between the first die 21 and the second die 22, and the impact component 3 can drive the second die 22 to move toward the direction close to the first die 21 and cooperate with the first die 21 to perform the blanking process on the sheet 4.

[0034] The punching device provided in the present application has a simple structure and can flexibly replace the first die 21 and the second die 22 to obtain different punched parts through punching processing, thereby effectively reducing the processing and manufacturing cost of the punching device itself and the punching processing cost.

[0035] like Figures 1 to 3 As shown, the blanking device provided by the present application, wherein the first die 21 is a female die, the first die 21 is provided with a blanking hole 211, the second die 22 is a male die, the second die 22 is provided with a blanking protrusion 221, along the direction perpendicular to the mounting plane 11, the projection of the side wall of the blanking hole 211 coincides with the projection of the peripheral side of the blanking protrusion 221, the blanking protrusion 221 can be fitted and inserted into the blanking hole 211, and the peripheral surface of the blanking protrusion 221 is in contact with the hole wall of the blanking hole 211, thereby forming an annular shear surface to blank the sheet 4 to obtain a blanked part.

[0036] Optionally, in the punching device provided in the present application, the punching hole 211 is a through hole 2311 or a blind hole recessed along a direction perpendicular to the mounting plane 11 .

[0037] When the punching hole 211 is a through hole 2311, a hole structure can be formed on the mounting plane 11 accordingly, and a carrying plate can be connected to the frame 1 so that the punched parts can directly fall into the carrying plate.

[0038] When the punching hole 211 is a blind hole, the depth of the blind hole can be increased so that the punched parts obtained by punching are temporarily stored in the blind hole and are collected uniformly after a preset number of punchings.

[0039] like Figures 1 to 3As shown, the blanking device provided by the present application, wherein the bracket 23 also includes a column 232, the column 232 is perpendicular to the installation plane 11, one end of the column 232 passes through the first die 21 and is detachably connected to the frame 1, and the other end of the column 232 is detachably connected to the limit plate 231. In this way, while achieving the positioning connection between the bracket 23 and the frame 1, the relative position between the bracket 23 and the first die 21 is also fixed, simplifying the assembly steps between the bracket 23 and the first die 21, and ensuring the relative setting accuracy of the first die 21 and the second die 22, thereby ensuring the blanking effect of the first die 21 and the second die 22.

[0040] Alternatively, if Figures 1 to 3 As shown, the blanking device provided by the present application is provided with at least two columns 232, and the two columns 232 are parallel to each other and spaced apart. By arranging multiple columns 232, relative rotation between the bracket 23 and the frame 1, between the bracket 23 and the first mold 21, and between the first mold 21 and the frame 1 can be effectively prevented, which causes the first mold 21 and the second mold 22 to be unable to be arranged relative to each other in a direction perpendicular to the installation plane 11.

[0041] Optionally, one column 232 may also be provided, and a circumferential limiting structure may be provided between the column 232 and the frame 1, between the column 232 and the first mold 21, and between the column 232 and the limiting plate 231 to prevent relative rotation between the column 232 and the frame 1, between the column 232 and the first mold 21, and between the column 232 and the limiting plate 231, resulting in the first mold 21 and the second mold 22 being unable to be relatively arranged in a direction perpendicular to the mounting plane 11.

[0042] Specifically, the column 232 can be used as a polygonal column, or limiting keys can be set between the column 232 and the frame 1, between the column 232 and the first mold 21, and between the column 232 and the limiting plate 231.

[0043] like Figure 1 and Figure 3 As shown, the blanking device provided by the present application, wherein the impact assembly 3 includes an impact column 31, the impact column 31 passes through the through hole 2311, the second die 22 is connected to the end of the impact column 31 toward the mounting plane 11, and the impact column 31 can reciprocate in a direction perpendicular to the mounting plane 11 to drive the second die 22 to move toward a direction close to the first die 21 so as to cooperate with the first die 21 to perform blanking processing on the plate 4.

[0044] The impact column 31 and the through hole 2311 remain stationary in the circumferential direction to ensure that the first mold 21 and the second mold 22 are accurately arranged relative to each other along a direction perpendicular to the installation plane 11 .

[0045] Optionally, the impact column 31 is a polygonal column and the through hole 2311 is a polygonal hole. When the impact column 31 passes through the through hole 2311, the outer peripheral surface of the impact column 31 is in contact with the hole wall of the through hole 2311 to achieve circumferential limitation between the impact column 31 and the limiting plate 231.

[0046] For example, the impact column 31 is a quadrangular column, and the through hole 2311 is a rectangular hole, which has the advantage of being easy to process.

[0047] like Figure 1 and Figure 3 As shown, the blanking device provided by the present application, wherein the end of the impact column 31 that is away from the mounting plane 11 is connected with a first stopper 311, and along the radial direction of the through hole 2311, the size of the first stopper 311 is smaller than the aperture of the through hole 2311. By providing the first stopper 311, the movement range of the impact column 31 in the direction perpendicular to the mounting plane 11 can be limited, thereby preventing the impact column 31 from moving in the direction close to the first mold 21 and falling off from the through hole 2311.

[0048] like Figure 1 and Figure 3 As shown, the blanking device provided by the present application, wherein the impact assembly 3 also includes an elastic member 32, the elastic member 32 is sleeved on the impact column 31 and is located between the first limiting member 311 and the limiting plate 231, one end of the elastic member 32 abuts against the first limiting member 311, and the other end of the elastic member 32 abuts against the first limiting member 311.

[0049] When the impact column 31 drives the second die 22 to move toward the first die 21, the first limit member 311 applies pressure to the elastic member 32, and the elastic member 32 is compressed and generates an elastic restoring force. After the first die 21 and the second die 22 cooperate to complete a punching process, under the action of the elastic restoring force, the second die 22 can move away from the first die 21 for separation from the first die 21. At this time, the plate 4 can be moved to prepare for the next punching process.

[0050] like Figure 1 and Figure 3 As shown, the blanking device provided by the present application, wherein the impact assembly 3 also includes a guide rod 33 and an impact block 34, the first end of the guide rod 33 is connected to the side of the first limit member 311 away from the mounting plane 11, and the second end of the guide rod 33 extends in a direction perpendicular to the mounting plane 11 in a direction away from the first limit member 311; the impact block 34 is sleeved on the guide rod 33, and the impact block 34 can reciprocate along the guide rod 33 and transmit the impact force to the second mold 22 through the first limit member 311 and the impact column 31.

[0051] When punching, the impact block 34 is first driven to move in a direction away from the first limit piece 311, and then a force is applied to the side of the impact block 34 away from the first limit piece 311 toward the first limit piece 311, so that the impact block 34 moves quickly in a direction close to the first limit piece 311, and pushes the first limit piece 311, the impact column 31 and the second die 22 to quickly impact and approach the first die 21. Under the action of the force, the first die 21 and the second die 22 cooperate to cut the sheet 4.

[0052] Alternatively, if Figure 1 and Figure 3 As shown, the blanking device provided in the present application has a second limiter 331 connected to the second end of the guide rod 33 to limit the impact block 34 to prevent the impact block 34 from falling off the guide rod 33 .

[0053] The punching device provided in the present application has a simple structure and can flexibly replace the first die 21 and the second die 22 to obtain different punched parts through punching processing, thereby effectively reducing the processing and manufacturing cost of the punching device itself and the punching processing cost.
