Abstract
The utility model relates to a mold core clamping device of a numerical control punch, in particular to a damage-prevention clamping device which comprises a clamping block A and a clamping block B which are in the pair relation and correspondingly provided with cambered surfaces, a rotating pin and a locking handle. One side of each clamping block is provided with a pin hole for connecting the rotating pin; the other side of the clamping block A is provided with a threaded hole and the other side of the clamping B is provided with a through hole; the locking handle penetrates the through hole on the clamping block B and is connected with the threaded hole on the clamping block A. According to the damage-prevention clamping device, a mold core is specially provided with a special clamping surface, thereby changing the situation that the contact surface between the prior clamping device and a workpiece is small but the pressure is concentrated so that the workpiece is damaged; the change of the clamping surface contacted with the workpiece into the cambered or molded surface adapted to the surface shape of the workpiece enlarges the contact surface between the clamping surface and the surface of the workpiece and avoids to damage the surface of the mold. The damage-prevention clamping device has simple and convenient operation and good effect, and can be adapted to the adjustment of the height of different molds at various stations of the numerical control turret punch after being provided with a transition sleeve.
Description
Technical field
The utility model relates to a kind of antisitic defect clamping device, relates in particular to the maintenance of numerical control press upper mold core, the clamping device when installing.
Background technology
NC turret punch machine in use, core rod can occur wearing and tearing, influence cutting ability, need in time carry out sharpening.Repeatedly behind the sharpening, the core rod height can occur and reduce, at this moment just patrix and die shank/seat need be reinstalled,, guarantee effective stamping-out to adjust the height of its cutting edge.In the past, when this situation occurring, be that core rod is fixed on the bench vice, unclamp with die shank/seat between be connected, thereby adjustment highly.Because the core rod outer surface is to have very high-precision forming surface, during clamping, the clamping plane of bench vice forms line with the cylinder of core rod and contacts on bench vice, and the pressure of stress point is very big, very easily the damage that can not repair in the core surface generation.
The utility model content
The utility model provides a kind of clamping area and has been contacted by face between workpiece at above problem, thereby avoids can not repairing the numerical control press core rod clamping device of damage in the core surface generation.
The technical solution of the utility model is: comprise that a pair of correspondence is provided with the clamp A of cambered surface, clamp B, rotating dog and set lever; One side of two clamps is respectively equipped with the pin-and-hole that is used to connect rotating dog, and clamp A opposite side is provided with screwed hole, and clamp B opposite side is established through hole, and the through hole that set lever runs through on the clamp B links to each other with screwed hole on the clamp A.
Cambered surface on clamp A, the clamp B is respectively major arc, minor arc.
It also comprises base plate, and clamp A is fixed on the base plate.
Between the cambered surface of two clamps, be provided with an opening shaft to the spacer shell that cuts open seam.
The utility model is provided with special-purpose clamping face for formation die core specially, and it is too small to have changed in the past between clamping device and workpiece contact-making surface, thereby pressure is concentrated the situation of damage workpiece; The clamping face that will contact with workpiece is changed into arc or the forming surface adaptive with the surface of the work shape, has increased the contact area of clamping face and surface of the work, has avoided the damage of die surface.The utility model is easy and simple to handle, and is effective, establish spacer shell after, the use during the different mould adjustment height of can adaptive NC turret punch machine various stations.

The specific embodiment
As Fig. 1,2, the utility model comprises that a pair of correspondence is provided with the clamp A2 of cambered surface, clamp B4, rotating dog 6 and set lever 5; The side of two clamp clamp A2, clamp B4 is respectively equipped with the pin-and-hole that is used to connect rotating dog 6, clamp A2 opposite side is provided with screwed hole, clamp B4 opposite side is established through hole, and the through hole that set lever 5 runs through on the clamp B4 links to each other with screwed hole on the clamp A2.
Cambered surface on clamp A2, the clamp B4 is respectively major arc, minor arc.
It also comprises base plate 1, and clamp A2 is fixed on the base plate 1.
Between the cambered surface of two clamp clamp A2, clamp B4, be provided with an opening shaft to the spacer shell 3 that cuts open seam.1/2 upper mould 7 is arranged in the spacer shell 3.
As Fig. 3,4,5, the utility model can not established spacer shell 3, the cambered surface between clamp A2, clamp B4 is designed to the outer surface of 1/4 upper mould 8 adaptive, directly 1/4 upper mould 8 is clamped between the cambered surface between clamp A2, clamp B4.Unclamp set lever 5, clamp A2, clamp B4 are opened, 1/4 upper mould 8 is inserted in the clamp A2 cambered surface, close clamp B4, operation set lever 5 makes clamp A2, clamp B4 clamp 1/4 upper mould 8.
Claims (4)
