Description
Technical field
The present invention relates to a kind of punching mechanism of shape processing machine, particularly a kind of punching mechanism of the processing machine of processing strip-like profile, belongs to shape technical field of processing equipment.
Background technology
A large amount of banded bus bars that use copper aluminium material matter in power industry, the processing of bus bar mainly comprises punching and shearing.Existing bus processing machine generally all adopts the longitudinal feed of feeding clamp clamping bus bar, then coordinate can transverse shifting die frame combination and unit head part that can transverse shifting carry out punching, shearing work by hitting mould.This kind of structure need to be equipped with respectively independent servo-actuating device by feeding clamp, die assembly, unit head, just can complete the effect of necessary independent driving.The function of its modeling tool of the processing machine of this kind of structure and the function of mobile pitch-row drive the die frame transverse shifting at mould place to realize by same servo-actuating device, and unit head also must have independent servo-actuating device to drive its active lateral to move to ensure to keep synchronizeing with mould at any time, or modeling function needs independent a set of servo control mechanism to drive in order to change the position of mould bases and unit head, the mould that makes it to select has in advance been aimed at the replacing of mould with unit head, then when needing mobile pitch-row, another set of servo control mechanism drives moved together with mould bases and the mould bases servo control mechanism function of mobile pitch-row of unit head, in order to avoid there is the problem that pressure inequality that unit head and mold center's deviation cause even cannot punching press, the punching press function that the process equipment of this kind of structure will complete the different moulds of quick selection all needs the independent driving mechanism of two covers to realize, exist cost high, energy consumption is large, control complicated, structure is loaded down with trivial details, poor reliability, trouble point is many, the drawbacks such as inconvenience maintenance.
The patent No. is that the Chinese utility model patent of ZL201220012280.4 discloses a kind of strip-like profile processing machine, it is that pressure apparatus is fixedly installed, and setting can be with the pressure transfer device of the passive movement of mould on pressure apparatus, in the time that needs carry out punching operation, pressure transfer device is connected with selected mould and moves to job position with mould and die frame, carries out punching operation.This structure can be saved the servo motor driving device of a set of driving unit head transverse shifting, makes the designs simplification of machine, its low cost of manufacture.But also there is the defect that need to return to die change point and carry out the control program more complicated that modeling causes because of die frame in this kind of machine.
Summary of the invention
For the above-mentioned defect existing in prior art, the invention provides and a kind ofly can make to control simpler, mould and choose the punching mechanism of shape processing machine more easily.
The present invention is achieved by the following technical solution: a kind of punching mechanism of shape processing machine, comprise the inner hydraulic cylinder that the pressure mechanism of the die frame of punching die, setting corresponding to described die frame is at least installed, is connected with described pressure mechanism, its special character is, on described pressure mechanism, the part corresponding with die frame is fixed with a press strip longitudinally arranging along die frame, the upper end of the each mould in die frame is provided with movable sliding shoe, and described sliding shoe is connected with the thrust unit being arranged on mould.
In the present invention, sliding shoe is arranged on the upper end of mould, can control the position of sliding shoe by thrust unit.In the time that pressure mechanism presses down, press strip can contact and it is exerted pressure with the sliding shoe on selected mould, completes punching press action thereby driven mold is descending together.The sliding shoe on modeling tool does not contact with press strip.
The moving direction of the sliding shoe in the present invention can have multiple, considers the simple and reliability of structural design, and described sliding shoe is connected with the thrust unit that can laterally promote along die frame being arranged on mould, and sliding shoe can be along die frame transverse shifting.In the present invention, be arranged on the sliding shoe of mould upper end under release state, can make sliding shoe not overlap with the press strip position being arranged on pressure mechanism.When sliding shoe is in the time retracting state, it can overlap with the press strip position being arranged on pressure mechanism, and when pressure mechanism presses down, press strip can be exerted pressure to the sliding shoe on mould, completes punching press action thereby driven mold is descending together.By controlling the release of sliding shoe and retracting, can complete easily choosing of mould.
The movement of the sliding shoe in the present invention can also adopt the form of vertical lift, and described sliding shoe is connected with the thrust unit that can vertically promote being arranged on mould, and described sliding shoe is along mold axis direction vertical lift.In the present invention, sliding shoe on mould can be along mold axis vertical lift, elected in when a certain mould, the sliding shoe on this mould is raised, when pressure mechanism presses down, press strip can be to choosing the sliding shoe on mould to exert pressure, and completes punching press action thereby driven mold is descending together.And thrust unit on unchecked mould is failure to actuate and is made it highly constant.Can complete easily choosing of mould by the lifting of controlling sliding shoe.
Thrust unit in the present invention can be cylinder or electromagnet or rack and pinion drive mechanism or lead-screw drive mechanism, or any structure that other can drive sliding shoe to move of the prior art.
Pressure mechanism in the present invention can adopt hydraulic cylinder of the prior art to be arranged on the version of die frame top, also can adopt hydraulic cylinder to be arranged on the version of die frame below.Consider the simple and reliability of structural design, in the present invention, described pressure mechanism is the frame structure being connected to form by four pull bars by top board, lower platen, described top board is positioned at the top of die frame, described lower platen is positioned at the below of die frame, described pressure mechanism is fixed on frame by the center platen that is located at die frame bottom, and hydraulic cylinder is connected between center platen and lower platen and with lower platen, and described press strip is connected in the bottom of described top board.
The present invention is simple, it by arranging press strip and movable sliding shoe being set on mould on pressure mechanism, make the position of controlling sliding shoe by controlling thrust unit make the press strip on pressure mechanism contact or not contact with sliding shoe, the punching press of having chosen that can complete easily mould is moved, and its control mode is simple, reliable.
