Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

As shown in fig. 2, for the utility model discloses a structural schematic diagram, it is used with system spring machine cooperatees usually, realizes punching and the synchronization of system spring process (as shown in fig. 1, for the utility model discloses the structural schematic diagram of abnormal shape spring, it comprises first parallel plate, second parallel plate and connecting plate, first parallel plate and second parallel plate are parallel to each other, and the connecting plate is used for connecting first parallel plate and second parallel plate, has seted up the through-hole on first parallel plate and the second parallel plate; in this embodiment, punch the operation through this structure of punching to panel, the panel that the system spring machine will have punched simultaneously bends to make the special-shaped spring that fig. 1 is shown). The device mainly comprises a vertical plate 1, a rotating shaft 2, a cam 3, a lever arm 4, a telescopic rod 5, a first fixing block 6, a supporting plate 7, a sliding strip 8, a second fixing block 9, a transition plate 10, a moving plate 11, a guide post 12, a return spring 13, a first fixing table 14, a second fixing table 15, a third fixing table 16, a punching post 17 and the like.

Wherein, riser 1 is fixed on the processing board usually, and backup pad 7 is fixed in riser 1 one side (accessible screw fastening's mode realizes fixedly). The pivot 2 rotationally installs in riser 1 one side, and pivot 2 realizes the pivoted under drive arrangement's drive (in this embodiment, servo motor is chooseed for use to drive arrangement, and servo motor fixes in riser 1 opposite side, and servo motor's output shaft links to each other with pivot 2, chooses for use servo motor can the accurate control pivot 2 the rotational speed and turn to). The cam 3 is fixed on the rotating shaft 2 and rotates synchronously with the rotating shaft 2. The lever arm 4 is arranged on one side of the vertical plate 1 and is matched with the cam 3 for use (the lever arm 4 and the supporting plate 7 are arranged on the same side of the vertical plate 1). The telescopic rod 5 is fixed at one end of the lever arm 4 and faces the supporting plate 7 (due to the influence of the shape of the cam 3, the cam 3 rotates downwards for a circle under the driving of the rotating shaft 2, the protruding part of the cam 3 can be in contact with the lever arm 4 to drive the lever arm 4 to swing to a certain extent, and therefore the telescopic rod 5 fixed at the other end of the lever arm 4 does linear motion on the supporting plate 7).

The sliding strip 8 is slidably mounted on one side of the supporting plate 7, and the first fixing block 6 and the second fixing block 9 are fixed at two ends of the sliding strip 8 in a screw fastening mode (the first fixing block 6 is connected with the telescopic rod 5). The transition plate 10 is fixed on the second fixed block 9, and the moving plate 11 is fixed on the transition plate 10, so that the moving plate 11 is driven to do linear motion on the support plate 7 along with the linear motion of the telescopic rod 5.

As shown in fig. 3, the first fixed stage 14 is fixed on a side of the moving plate 11 away from the supporting plate 7, the second fixed stage 15 is fixed on the first fixed stage 14, and the third fixed stage 16 is fixed on the second fixed stage 15 (a through groove 162 is formed in the third fixed stage 16, the through groove 162 penetrates through the first fixed stage 14, the second fixed stage 15, and the third fixed stage 16 for conveying the plate to be punched, and guide holes 161 are formed in the peripheral surface of the third fixed stage 16 at intervals). Two guide posts 12 are fixed to one side of the moving plate 11 and are inserted into the guide holes 161 (the number of the guide posts 12 and the number of the guide holes 161 are the same).
