Abstract
A punch head quick-change mechanism for a steel plate spring punching porous die relates to the field of dies for machining steel plate springs. Mainly be for solving the problem that the drift on the change cut-out press is wasted time and energy at present and design. It includes the drift fixed block, set up microscler heavy groove on the drift fixed block, it has three downwardly extending's square head bolt mounting hole to open at the tank bottom of heavy groove, three square head bolt is installed respectively in three square head bolt mounting hole, the square head of three square head bolt is located heavy inslot, and the square head of square bolt contacts with two lateral walls of heavy groove, the below of every square head bolt mounting hole all has a drift mounting hole, drift mounting hole and square head bolt mounting hole intercommunication, the upper portion of three drift stretches into the interior back of three drift mounting hole respectively with the lower part threaded connection of square head bolt. The advantage is that the drift installation is convenient with dismantling, labour saving and time saving.
Description
The technical field is as follows:
the utility model relates to a mould field that processing leaf spring used specifically is a drift quick change mechanism on for three hole moulds are dashed to leaf spring.
The background art comprises the following steps:
the three punches are applied to punching three-hole dies at present, an upper fixing block of the die needs to be detached when the punches are replaced, the operation space is narrow due to limitation of a material pressing mechanism, operation for 30-40 minutes can be completed by cooperation of two persons, time and labor are wasted, and production is delayed.
The invention content is as follows:
the utility model aims to solve the technical problem that a drift is changed labour saving and time saving's a drift quick change mechanism that is used for leaf spring to dash porous mould is provided.
The above object is achieved by: the punch head structure comprises a punch head fixing block, a long sinking groove is formed in the punch head fixing block, three square-head bolt mounting holes extending downwards are formed in the bottom of the sinking groove, three square-head bolts are mounted in the three square-head bolt mounting holes respectively, the square heads of the three square-head bolts are located in the sinking groove, the square heads of the square bolts are in contact with two side walls of the sinking groove, a punch head mounting hole is formed in the lower portion of each square-head bolt mounting hole and communicated with the corresponding square-head bolt mounting holes, the upper portions of the three punch heads extend into the three punch head mounting holes respectively and then are in threaded connection with the lower portions of the square-head bolts, planes are arranged in the middle portions of four side faces (front side face, rear side face, left side face and right side face) of each punch head, and a wrench is clamped on the two symmetrical planes when the punch heads are mounted and dismounted. The square head bolt is arranged, so that the square head bolt can not rotate when the punch is replaced.
The punch fixing block is connected to the upper fixing plate through a bolt, the upper fixing plate is connected to the upper base plate through a bolt, the material pressing plate is arranged below the upper base plate, a screw rod mounting hole is formed in the material pressing plate, a screw rod is arranged in the bolt mounting hole of the material pressing plate, the upper end of the screw rod is fixed to the upper base plate, a spring is sleeved on the screw rod, namely the upper end of the spring is abutted to the upper base plate, and the lower end of the spring is abutted to the material pressing plate; the die handle is fixed on the upper bottom plate; the material pressing plate is provided with punch through holes at positions corresponding to the three punches.
The utility model has the advantages that: when the punch is replaced, the punch is only required to be screwed off from the square-head bolt, so that the punch is convenient to mount and dismount, and time and labor are saved; the time for replacing the punch on the line is shortened, and the production efficiency is improved.
