[0038] The inner part of the stamping seat 101 and the stamping die 104 is respectively provided with a sliding hole one and a sliding hole two, the ejector pin 106 can slide in the sliding hole one of the stamping seat 101 and the sliding hole two of the stamping die 104, and the two ends of the spring one 105 are fixedly connected with the stamping seat 101 and the U-shaped plate frame 107.

[0039] In the embodiment, the stamping device for metal product production is used, first, the metal piece is placed on the stamping die 104, the hydraulic cylinder 102 is started, the stamping head 103 is driven to move downward, the stamping die 104 is stamped through the stamping head 103, and the metal piece is stamped and formed;

[0040] In the process, with the continuous stretching of the output end of the hydraulic cylinder 102, the strip-shaped plate 201 is driven to move downward synchronously, and the two groups of pull rods 203 are driven to move downward, when the lock block 204 at the bottom of the pull rod 203 contacts the U-shaped plate frame 107, the lock block 204 is blocked by the U-shaped plate frame 107, is extruded, the bottom edge of the lock block 204 is provided with an inclined chamfer two, the lock block 204 is extruded into the pull rod 203 while the pull rod 203 drives the lock block 204 to move downward, the lock block 204 compresses the spring two 205, and drives the moving plate 206 to move, until the lock block 204 is completely moved into the sliding groove of the pull rod 203, one side of the pull rod 203 is in contact with the inner side wall of the U-shaped plate frame 107, and the pull rod 203 continues to move downward;

[0041] When the lock block 204 corresponds to the plug-in hole two 209 of the U-shaped plate frame 107, the extrusion of the lock block 204 is released, the spring two 205 rebounds, and part of the lock block 204 moves out of the pull rod 203 and is clamped in the plug-in hole two 209, under the cooperation of the lock block 204, the connection between the pull rod 203 and the U-shaped plate frame 107 is realized;

[0042] At this time, the metal piece is punched, the hydraulic cylinder 102 drives the punch head 103 to separate from the punch die 104, and when the punched metal piece is tightly clamped in the punch die 104, the output end of the hydraulic cylinder 102 is continuously retracted and moves upward, thereby driving the strip-shaped plate 201 and the lifting rod 203 to move upward synchronously. Before this, the locking block 204 is buckled in the second plug-in interface 209, and at this time, the lifting rod 203 drives the U-shaped plate frame 107 to move upward synchronously through the locking block 204. Through the upward movement of the U-shaped plate frame 107, the ejector pin 106 is driven to move upward synchronously, and the spring 105 is compressed at the same time. With the upward movement of the ejector pin 106, the punched metal piece is ejected from the punch die 104 through the ejector pin 106;

[0043] Through this operation, after the metal piece is punched, the metal piece can be automatically ejected without manual intervention, improving work efficiency. Moreover, compared with the action of the spring alone, this structure can better eject the metal piece and will not cause the metal piece to be difficult to eject due to the spring force alone. At the same time, the device does not need to be driven by electricity or gas, thereby saving certain energy consumption, improving the use effect of the device, and meeting the actual use requirements.

[0044] When the hydraulic cylinder 102 drives the U-shaped plate frame 107 to move upward to the moving height through the lifting rod 203, the first plug-in interface 207 of the moving plate 206 is inserted in the L-shaped extrusion plate 202. Since the bottom end of the L-shaped extrusion plate 202 is provided with an inclined chamfer one, the moving plate 206 is extruded to one side under the condition of the inclined surface of the L-shaped extrusion plate 202 while moving upward, thereby driving the locking block 204 to move into the lifting rod 203. At this time, the locking block 204 is separated from the second plug-in interface 209 of the U-shaped plate frame 107, thereby releasing the connection between the U-shaped plate frame 107 and the lifting rod 203. At this time, the spring 105 rebounds and resets, and drives the U-shaped plate frame 107 to move downward and reset. The next time, the metal piece is punched.

[0045] It should be noted that the lower portion of the U-shaped plate frame 107 is provided with a limiting plate, and the limiting plate is fixedly connected with the punch seat 101. When the locking block 204 preliminarily extrudes the U-shaped plate frame 107, the limiting plate can limit the downward movement of the U-shaped plate frame 107.

[0046] Further;

[0047] In an optional embodiment, the first plug-in interface 207 of the moving plate 206 is provided with a roller 208, and the roller 208 is rotatably connected with the moving plate 206 through a bearing.

[0048] The top two ends of the U-shaped frame 107 are provided with a strip-shaped slot, and a roller two 210 is arranged in the strip-shaped slot. The two ends of the roller two 210 are rotatably connected to the U-shaped frame 107 through bearings.

[0049] In this embodiment, the plug-in interface one 207 is provided with a roller one 208. When the plug-in interface one 207 provided on the moving plate 206 slides on the L-shaped extrusion plate 202, the roller one 208 can reduce the friction between the moving plate 206 and the L-shaped extrusion plate 202, and improve the extrusion effect on the moving plate 206.

[0050] Through the arrangement of the roller two 210, when the inclined surface of the lock block 204 contacts the U-shaped frame 107, the friction between the lock block 204 and the U-shaped frame 107 can be reduced, the extrusion effect on the lock block 204 can be improved, and the use effect of this structure can be improved.

[0051] The utility model discloses a working principle and use flow: this metal product production is with punch device, when using, first place the metal piece on the punch die 104, through starting hydraulic pneumatic cylinder 102, and drive punch head 103 to move down, through punch head 103 to punch the punch die 104, to form the punch to the metal piece, in this process, along with the output end of hydraulic pneumatic cylinder 102 constantly stretch, and then drive strip board 201 synchronous down, and then drive two group of pull rod 203 down, when the lock block 204 of pull rod 203 bottom contacts with U type board frame 107, when lock block 204 is blocked by U type board frame 107, will extrude lock block 204, because the bottom edge of lock block 204 is provided with inclined chamfer no.When the hydraulic cylinder 102 drives the U-shaped plate frame 107 to move up to the moving height through the lifting rod 203, the insertion interface one 207 of the moving plate 206 is inserted on the L-shaped extrusion plate 202 at this time, because the bottom end of the L-shaped extrusion plate 202 is provided with an inclined chamfer one, when the moving plate 206 moves up, and under the condition of the inclined surface of the L-shaped extrusion plate 202, the moving plate 206 is extruded to one side, the moving plate 206 drives the locking block 204 to move into the lifting rod 203, at this time, the locking block 204 is separated from the insertion interface two 209 of the U-shaped plate frame 107, at this time, the connection between the U-shaped plate frame 107 and the lifting rod 203 is released, at this time, the spring one 105 rebounds and resets, and drives the U-shaped plate frame 107 to move down and reset, and waits for the next metal piece to be punched.
