As shown in Figure 1-3, Fig. 2 omits support rod 20, a kind of adjusting punch that present embodiment provides, packet It includes: 10, two two that is set to the support rod 20 of rack 10 along 10 transverse direction of rack, can be slided with respect to support rod 20 of rack Connector 30, the two groups of punching components and driving assembly for being respectively arranged at two connectors 30；Punching component includes passing through respectively The cavity plate disk 402 that bearing is connected to the punch-pin disk 401 for being correspondingly connected with part 30 and cooperates with punch-pin disk 401, two punch-pin disks 401 Central axes be located at same level straight line, the central axes of two cavity plate disks 402 are located at same level straight line, and driving assembly is for driving Corresponding punch-pin disk 401 and cavity plate disk 402 is moved to rotate along respective central axes.

Cavity plate disk 402 and punch-pin disk 401 are prior art construction, due to not being related to the improvement of the utility model, herein not It repeats again.

Connector 30 by same group of punching component cavity plate disk 402 and punch-pin disk 401 connect, adjust two groups of punching components Between position when, connector 30 is slided with respect to support rod 20, and bearing is connected to cavity plate disk 402 and punch-pin on the connector 30 Disk 401 moves simultaneously, and during adjustment, the punch-pin disk 401 and cavity plate disk 402 of same group of punching component keep precisely aligning, if Two support rods 20 are set, guarantee that connector 30 while sliding on support rod 20, prevents connector 30 relative to support rod 20 It rotates.

Specifically, driving assembly includes along rack 10 to realize that driving assembly is steadily driven between punching component respectively Transverse direction bearing is connected to the shaft 501 of rack 10, is coaxially disposed the driving gear 502 in shaft 501, coaxial arrangement in recessed First driven gear 503 of mould 402 and coaxial arrangement are in the second driven gear of punch-pin disk 401, the first driven gear 503 It is engaged with the second driven gear 504, driving gear 502 is engaged with the first driven gear 503.

It is connected by shaft 501 with extraneous device of rotation driving is connect, such as motor, motor-driven rotatable shaft 501 drives master Moving gear 502 rotates, and driving gear 502 drives the first driven gear 503 engaged with driving gear 502 or the second driven tooth 504 rotation of wheel, so that the rotation of another driven gear be driven to be punched.

It can also be adjusted to realize in puncher operation process, 501 side of shaft is equipped with slide unit 5011, driving gear 502 inner rings are equipped with the through slot cooperated with slide unit 5011, and driving gear 502 can be slided along 501 axial direction of shaft, driving gear 502 are connect by bearing with connector 30.

The cooperation of slide unit 5011 and through slot passes through connection while making shaft 501 smoothly driving gear 502 be driven to rotate Part 30 connects driving gear 502, cavity plate disk 402 and punch-pin disk 401, in adjustment process, except guarantee punch-pin disk 401 and cavity plate Except the accurate contraposition of disk 402, it is ensured that between driving gear 502, the first driven gear 503 and the second driven gear 504 Stable drive makes to be adjusted in the puncher course of work, without shutting down.

Specifically, punch-pin disk 401, cavity plate disk 402 and driving gear 502 are connected to connection by tapered roller bearing respectively Part 30.

Since in use process, the bearing at cavity plate disk 402, punch-pin disk 401 and driving gear 502 requires radial direction Load-bearing, other adjustment process middle (center) bearing axial direction stress, therefore use tapered roller bearing, while tapered roller bearing is suitable For puncher high-speed production operation.

Be connector 30 during making adjustment with respect to 20 smooth sliding of support rod, prevent slip angle be deviated cause it is recessed Mould 402 and the damage of 401 junction of punch-pin disk, connector 30 are equipped with sleeve 60, and sleeve 60 is sheathed on support rod 20, sleeve 60 Internal diameter is equal with the diameter of support rod 20.

It further include the adjusting screw rod 70 that bearing is connected to rack 10, connector 30 is equipped with the spiral shell cooperated with adjusting screw rod 70 Hole, the central axes of adjusting screw rod 70 and the central axes of support rod 20 are parallel to each other.

It is adjusted using adjusting screw rod 70, it is convenient and efficient.

To avoid being in contact abrasion during two adjustment of punch-pin disk 401, two sleeves 60 on same support rod 20 The distance between less than the distance between two punch-pin disks 401.In adjustment process, two sleeves 60 offset, and guarantee two punch-pin There are gaps between disk 401.

Above embodiment is only the certain preferred embodiments of the utility model, cannot limit the utility model with this The range of protection, the variation and replacement of any unsubstantiality that those skilled in the art is done on the basis of the utility model Belong to the utility model range claimed.
