Further, during the process that the sliding plate 41 gradually slides along the straight groove 401 from the clamping position, the transmission rod 42 is in an inclined state, as shown in fig. 11 and 12, that is, in an inclined state with respect to the long side direction of the fixed plate 4, and then when the sliding plate 41 slides, the transmission rod 42, which is always in an inclined state, gradually presses the rolling column 52 disposed on the transmission column 5, and then the rolling column 52 gradually slides upwards along the inclined transmission rod 42, that is, drives the rotating column to move towards the inside of the fixed plate 4, so that the first elastic member 51 stores the force, and the first elastic member 51 is a tension spring, and then under the elastic force of the tension spring, the transmission column 5 has a tendency to move towards the outside of the fixed plate 4.
In the invention, the movement stroke of the sliding plate 41 can be determined by arranging the second rack 312 and the stamping position of the stamping plate 2, so that the movement stroke of the sliding plate 41 is matched with that of the stamping mechanism, the clamping component on the sliding plate 41 clamps the workpiece before the stamping block 23 contacts the stamping part, and after stamping and after the stamping plate 2 is completely separated from the stamping part, the pushing component starts to drive the stamping part to push.
In the present invention, when the punching mechanism is at the uppermost position, the sliding plate 41 is at the release position and the clamp blocks 411 are in the released state, and then when the punching mechanism is at the lower position, the sliding plate 41 is at the clamp position and the two clamp blocks 411 clamp the member to be machined.
When the stamping device is used, as shown in fig. 1, from left to right, a plurality of stamping blocks 23 are respectively provided and then sequentially stamped by each die to form a product, specifically, when the stamping device is actually used, firstly, the stamping device moves downwards, in the process of downward movement, the stamping device drives the sliding plate 41 and the sliding column 412 to return to the position of the notch of the straight groove 401 along the inclined groove 403 through the driving of the driving component, namely, the sliding plate 41 is driven to move to the position of the clamping position, then, the clamping block 411 is in the state of clamping the to-be-stamped part, the sliding plate 41 is moved downwards and stamps the to-be-stamped part which is already clamped, then, after stamping, the stamping device moves upwards, the stamping plate 2 and the stamping block 23 both move upwards, specifically, in the process of moving upwards, the stamping plate 2 also moves upwards, then, the connecting block 33 and the second rack 312 which are connected are driven to move upwards, then, the transmission gear 313 thereof is driven to rotate, so that the first rack 311 which is meshed with the transmission gear 313 rotates, so that the first rack 311 drives the sliding column 412 and the sliding column 41 which is connected with the sliding column 412, then, the sliding block 411 is connected with the sliding block 41, and the clamping block 411 is driven to move towards the direction of the clamping groove, and then, the clamping block 411 of the sliding plate is driven by the sliding block 41, and the vertical sliding block 401, so that the sliding block 23, and the sliding block can move, and the sliding block 23, and then, and each sliding block can move continuously moves towards the clamping groove, and the clamping groove 401, and then, and each sliding block 411 of the sliding block 23, and the clamping groove 401, and each sliding block 23, and the sliding block 23 move downwards; when the sliding plate 41 moves, the transmission rod 42 connected to the side of the sliding plate 41 also moves synchronously, the sliding block 421 disposed at one end of the transmission rod 42 slides along the fixed plate 4, during the movement, the sliding plate 41 gradually contacts and presses the rolling column 52 disposed on the transmission column 5, because the transmission rod 42 is limited to the sliding plate 41 and the fixed plate 4, and is always in an inclined state during the movement, then the transmission rod 42 in the inclined state gradually presses the rolling column 52, so that the rolling column 52 gradually moves along the transmission rod 42 toward the direction close to the sliding plate 41, then the first elastic member 51 is charged, and the first elastic member 51 is a tension spring, then under the elastic force of the tension spring, the transmission column 5 has a tendency to move toward the outside of the fixed plate 4, at this time, the first elastic member 51 is in a charged state, then when the sliding column 412 is moved from the straight slot 401 to the slot position of the vertical sliding slot 402, because the elastic force of the first elastic member 51 is in a charged state, so that the elastic force of the transmission column causes the transmission rod 4 to move toward the outside of the fixed plate 4, then the transmission rod 42 and the transmission rod 41 are moved to the back and the sliding mechanism, so that the sliding block is released.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
