By setting up a stamping module, when the stamping is completed, the two first motors are started immediately to synchronously drive the two sliding sleeves to rotate, and the two sliding sleeves and the internal sliding slide rods are rotated toward the first rod body to an inclined state, and then the driving module is started to drive the first rod body, the ring body, the second rod body, the upper die, the triangular block, the slide rails and the connecting rods to rise synchronously as a whole. Since the two slide rods are inclined toward the first rod body, the two slide rails will be driven to move inward and synchronously drive the two connecting rods to rotate. Since the two connecting rods are arranged in opposite directions, the ring body can be driven to rotate, and the ring body in turn drives the second rod body and the upper die fixed thereto to rotate. In this way, when the upper die rises to remove the material, it will rotate with it, and the adhered metal debris can be thrown off, so as to avoid the metal debris remaining adhered to the bottom of the upper die during continuous stamping from scratching the finished product and causing a decrease in precision.

DETAILED DESCRIPTION

[0044] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-7 In an embodiment of the present invention, a shield cover stamping and forming device includes: a base 100, a stamping module 200 and a driving module 300, the top of the base 100 is fixedly connected with a lower mold 110, the top of the base 100 is fixedly connected with two groups of supporting feet 120, the tops of the two groups of supporting feet 120 are respectively fixedly connected with a first frame plate 130 and a second frame plate 140, the inner sides of the first frame plate 130 and the second frame plate 140 are both provided with two limiting grooves 150, the outer side of the first frame plate 130 is provided with two connecting grooves 160, and the two connecting grooves 160 and the two limiting grooves 150 are respectively connected; the stamping module 200 is arranged on one side of the first frame plate 130, and can perform stamping operations; the driving module 300 is arranged in the first frame plate 130 and the second frame plate 140, and can perform continuous stamping in cooperation with the stamping module 200.

[0046] Specifically, the material is first placed on the lower mold 110, and then the two first motors 260 are started. The two first motors 260 synchronously drive the two sliding sleeves 261 to rotate, and the two sliding sleeves 261 and the internal sliding slide rods 270 are rotated to a state perpendicular to the base 100. Then the two second motors 320 are started. The two second motors 320 synchronously drive the two discs 350 to rotate eccentrically in the same direction, thereby driving the moving plate 340 to reciprocate in the return frame 330. Since the return frame 330 is limited, the moving plate 340 The movement in the X-axis direction will be converted into the movement in the Z-axis direction of the return frame 330, which will drive the two support rods 360 to move downward in the same direction, and then drive the first rod body 210, the ring body 211, the second rod body 220 and the upper mold 230 to press down synchronously, and the lower mold 110 will punch downward. In this process, when the return frame 330 in the first frame plate 130 moves downward, it will synchronously drive the two follower rods 331 in the corresponding positions to move downward. The downward movement of the follower rods 331 in the two first frame plates 130 will drive the two sets of triangle blocks 240 , the slide rail 250, the connecting rod 251 and the slide bar 270 are synchronously lowered. When the stamping is completed, the two first motors 260 are immediately started to synchronously drive the two sliding sleeves 261 to rotate, and the two sliding sleeves 261 and the internal sliding slide bar 270 are rotated toward the first rod body 210 to an inclined state, and then the driving module 300 is started to drive the first rod body 210, the ring body 211, the second rod body 220, the upper mold 230 and the triangular block 240, the slide rail 250 and the connecting rod 251 to rise synchronously as a whole. Since the two slide bars 270 are both moved toward the first rod body The ring body 210 is inclined, so the two slide rails 250 will be driven to move inward, and synchronously drive the two connecting rods 251 to rotate. Since the two connecting rods 251 are arranged oppositely, the ring body 211 can be driven to rotate, and the ring body 211 drives the second rod body 220 and the upper mold 230 fixedly connected thereto to rotate. In this way, when the upper mold 230 rises to remove the material, it will rotate with it, and the adhered metal debris can be thrown off, so as to avoid the metal debris remaining adhered to the bottom of the upper mold 230 during continuous stamping from scratching the finished product and causing a decrease in precision.

[0047] Embodiment 1

[0048] like Figure 2-5As shown, in this embodiment, the stamping module 200 includes: a first rod body 210, a second rod body 220, an upper die 230, a triangular block 240, a slide rail 250, a first motor 260 and a slide bar 270, the first rod body 210 is arranged on one side of the first frame plate 130, and the bottom end of the first rod body 210 is rotatably connected to the ring body 211; the second rod body 220 is fixedly connected to the bottom of the ring body 211; the upper die 230 is fixedly connected to the bottom end of the second rod body 220, and the upper die 230 matches the lower die 110; the triangular block 240 is arranged on the first frame plate 1 30, a slide groove 241 is provided on one side of the triangular block 240, and a follower block 242 is fixedly connected to the other side of the triangular block 240; the slide rail 250 slides in the slide groove 241, one end of the slide rail 250 is rotatably connected to the connecting rod 251, and one end of the connecting rod 251 is rotatably connected to the ring body 211; the first motor 260 is fixedly connected to one side of the second frame plate 140, and the driving end of the first motor 260 is fixedly connected to the sliding sleeve 261; the sliding rod 270 is slidably connected in the sliding sleeve 261, and the sliding rod 270 and the slide rail 250 are rotatably connected.

[0049] Furthermore, the driving ends of the two first motors 260 are fixedly connected to the center of the sliding sleeve 261, and the two sliding sleeves 261 are both opened. Since the two sliding sleeves 261 are both opened, the sliding rail 250 can drive the sliding rod 270 to slide in the sliding sleeve 261 when it is raised or lowered without interference.

[0050] In specific implementation, after the stamping is completed, the two first motors 260 are immediately started to synchronously drive the two sliding sleeves 261 to rotate, and the two sliding sleeves 261 and the internal sliding slide rods 270 are rotated toward the first rod body 210 to an inclined state, and then the driving module 300 is started to drive the first rod body 210, the ring body 211, the second rod body 220, the upper mold 230 and the triangular block 240, the slide rail 250 and the connecting rod 251 to rise synchronously as a whole. Since the two slide rods 270 are inclined toward the first rod body 210, Therefore, the two slide rails 250 will be driven to move inward, synchronously driving the two connecting rods 251 to rotate. Since the two connecting rods 251 are arranged in opposite directions, the ring body 211 can be driven to rotate, and the ring body 211 in turn drives the second rod body 220 and the upper mold 230 fixedly connected thereto to rotate. In this way, when the upper mold 230 rises to remove the material, it will rotate accordingly, and the adhered metal debris can be thrown off, thereby preventing the metal debris remaining adhered to the bottom of the upper mold 230 from scratching the finished product during continuous stamping, resulting in a decrease in precision.

[0051] Embodiment 2

[0052] On the basis of the first embodiment, in order to drive the stamping module 200 to perform continuous stamping operations, a driving module 300 is provided.

[0053] like Figure 2 and Figure 6As shown, in this embodiment, the driving module 300 includes: a fixed plate 310, a second motor 320, a return frame 330, a movable plate 340 and a disc 350, the two fixed plates 310 are respectively fixedly connected to the outer sides of the first frame plate 130 and the second frame plate 140; the two second motors 320 are respectively fixedly connected to the outer sides of the two fixed plates 310; the two return frames 330 are respectively slidably arranged in the first frame plate 130 and the second frame plate 140, and the two sides of the two return frames 330 are fixedly connected with follower rods 331, and the two groups of follower rods 331 are respectively slidably connected to the first frame plate 130 and the second frame plate The two limit grooves 150 of the plate 140; the two movable plates 340 are respectively slidably connected in the two return frames 330; the two discs 350 are respectively fixedly connected to the outer sides of the two movable plates 340, and the driving ends of the two second motors 320 are respectively fixedly connected to the eccentric points of the two discs 350; the two follower rods 331 located in the first frame plate 130 are both extended downward and fixedly connected to the follower block 242; the inner sides of the two return frames 330 are fixedly connected with support rods 360, and the inner ends of the two support rods 360 are fixedly connected to the top of the first rod body 210, and the two support rods 360 are detachable.

[0054] Specifically, the material is placed on the lower mold 110, and then the two first motors 260 are started. The two first motors 260 synchronously drive the two sleeves 261 to rotate, and the two sleeves 261 and the internal sliding slide rod 270 are rotated to a state perpendicular to the base 100. Then the two second motors 320 are started. The two second motors 320 synchronously and unidirectionally drive the two discs 350 to rotate eccentrically, thereby driving the movable plate 340 to reciprocate in the return frame 330. Since the return frame 330 is limited, the movement of the movable plate 340 in the X-axis direction will be converted into the movement of the return frame 330 in the Z-axis direction, thereby driving the two support rods 360 to move downward synchronously in the same direction, thereby driving the first rod body 210, the ring body 211, the second rod body 220 and the upper mold 230 to be pressed downward synchronously, and the lower mold 110 is punched downward.
