Description

Technical Field

[0001] The utility model belongs to the technical field of sheet punching machines, in particular to a sheet punching device. Background Art

[0002] A punching machine, also known as a punch press, is a mechanical device that uses dies and pressure to deform raw materials such as sheet metal and plate into the desired shape. Punching machines are also widely applicable, allowing users to interchange different forming tools to produce a variety of standard or non-standard specimens, such as soft sheets and films, for non-metallic material testing. Their simple, convenient, and safe operation significantly improves work efficiency.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] refer to Figures 1 to 3 A sheet punching device includes a workbench 1, a frame 2 arranged on the workbench 1, and a cutter 3 located above the workbench 1, wherein the frame 2 is provided with a vertical lifting mechanism 21 for driving the cutter 3 to rise and fall, and the cutter 3 is connected to the vertical lifting mechanism 21, and a pusher assembly 4 is provided on the frame 2, and the pusher assembly 4 is located in the vertical area of ​​the cavity 31 of the cutter 3;

[0020] When the vertical lifting mechanism 21 drives the cutter 3 downward, the pusher assembly 4 moves upward relative to the cutter 3 into the cavity 31;

[0021] When the cutter 3 of the vertical lifting drive mechanism moves upward, the pusher assembly 4 moves downward in the cavity 31 relative to the cutter 3 and pushes the sheet in the cavity 31 out.

[0022] Under this design, the worker places the material on the workbench 1, and then drives the cutter 3 downward through the vertical lifting mechanism 21. When the cutter 3 descends, the pushing component 4 rises relative to the cutter 3. When the pushing component 4 is located in the cavity 31 of the cutter 3, the cutter 3 cuts the material into sheets. Then the vertical lifting mechanism 21 drives the cutter 3 to ascend and reset, and the pushing component 4 descends relative to the cutter 3. The descending pushing component 4 pushes the sheet out of the cavity 31 of the cutter 3, and then the worker can take out the pushed out sheet; in this way, the sheet in the cavity 31 can be automatically pushed out, which is more convenient and quick.

[0023] Preferably, the pushing assembly 4 includes a pushing plate 41, a vertically arranged guide rod 42, and a movable column 43 slidably connected to the guide rod 42, one end of the guide rod 42 is connected to the frame 2, one end of the movable column 43 is detachably connected to the pushing plate 41, and the movable column 43 is movably connected to the vertical lifting mechanism 21.

[0024] Specifically, the movable column 43 is slidably connected to the guide rod 42, and the push plate 41 is connected to one end of the push plate 41. The distance between the push plate 41 and the cutter 3 is adjusted by sliding the movable column 43. When the vertical lifting mechanism 21 drives the cutter 3 downward, the push plate 41 is upward relative to the cutter 3. After the push plate 41 ascends to the cavity 31 of the cutter 3, the cutter 3 cuts the material into sheets, and then the vertical lifting mechanism 21 drives the cutter 3 to ascend and reset, and the push plate 41 descending relative to the cutter 3 will push out the sheet located in the cavity 31.

[0025] More preferably, a limiting portion is provided on the guide rod 42 , and the limiting portion is used to limit the upward movement of the movable column 43 .

[0026] Specifically, in order to prevent the sheet from being stuck very tightly in the cavity 31 of the cutter 3 and causing the push plate 41 to be lifted up by the sheet when the cutter 3 rises, a limit portion is provided to limit the rise of the movable column 43, thereby limiting the push plate 41 and pushing the sheet out.

[0027] In this embodiment, a connecting column 411 is provided on the top of the push plate 41, and the connecting column 411 is detachably connected to one end of the movable column 43 via a connecting piece 44;

[0028] The connecting piece 44 is a rubber sleeve.

[0029] Furthermore, by connecting the connecting post 411 of the push plate 41 to one end of the movable post 43 through a rubber sleeve, the push plate 41 can be easily disassembled for replacement or cleaning.

[0030] In this embodiment, the push plate 41 matches the shape of the cavity 31. The shape of the push plate 41 matches the shape of the cavity 31, which increases the contact area between the push plate 41 and the sheet material, and can better push the sheet material out.

[0031] Preferably, the vertical lifting mechanism 21 includes a screw 211 threadedly connected to the frame 2, a pressure plate 212 arranged at the bottom of the screw 211, a handwheel 214 arranged at the top of the screw 211, and two springs 213 located on both sides of the screw 211, one end of the spring 213 is connected to the pressure plate 212, and the other end is connected to the frame 2, and the cutter 3 is arranged at the bottom of the pressure plate 212; the movable column 43 is movably arranged on the pressure plate 212, and the end of the movable column 43 away from the guide rod 42 passes through the cavity 31.

[0032] Furthermore, the worker turns the handwheel 214, and the screw 211 drives the pressure plate 212 downward, which in turn drives the cutter 3 arranged at the bottom of the pressure plate 212 downward. The descending cutter 3 presses on the material, cutting the material into sheets with the same shape as the cavity 31 of the cutter 3. After cutting the material into sheets, the worker releases his hand from the handwheel 214, and the spring 213 makes the pressure plate 212 move upward, thereby driving the cutter 3 to move upward and reset, and the movable column 43 is movably provided on the pressure plate 212, and one end of the movable column 43 passes through the cavity 31, so that when the cutter 3 moves upward, the push plate 41 will push the sheet in the cavity 31 out.

[0033] More preferably, the cutter 3 is magnetically mounted on the bottom of the pressing plate 212. By fixing the cutter 3 to the bottom of the pressing plate 212 by magnetic attraction, the cutter 3 can be easily replaced. When the cutter 3 needs to be replaced to cut sheets of other shapes, the pusher plate 41 can be removed, and then a pusher plate 41 that matches the shape of the cavity 31 can be selected, so that the pusher plate 41 can better push the sheet out of the cavity 31.

[0034] 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 or modifications can be made without departing from the principles of the present invention. These improvements or modifications should also be regarded as the scope of protection of the present invention.
