Description
Technical field
The present invention relates to punching machine manufacturing field, more specifically to a kind of quick adjustment high efficiency punching machine.
Background technology
Punching machine, is exactly a punching type forcing press.In national product, Sheet Metal Forming Technology due to being processed than tradition machinery for
Have and save material and the energy, it is efficient, it is not high to operator's technical requirements and by various mould applications can make machinery plus
These advantages of the product that work is unable to reach, thus its purposes is more and more extensive.Punching production is primarily directed to plate.It is logical
Mould is crossed, blanking can be made, punching, shaping, drawing, finishing, fine, shaping, riveting and extrusion etc., are widely used in each
A field.Such as our switch socket, cup, kitchen cabinet, plate, computer housing, or even guided missile aircraft ... have very more
Accessory can be produced with punching machine by mould.
Common sheet metal punch process, major part use mechanical punch.Fluid pressure type punching machine is different using liquid according to it, there is oil
Pressure type punching machine and hydraulic type punching machine, are occupied the majority, hydraulic type punching machine is then chiefly used in huge mechanical or special machine using hydraulic type punching machine
Tool.When carrying out punching press on a large scale, more using row's punching, the row's red needle set by upper mold is adjusted and controls, still
It controls complicated, it is necessary to be controlled to each red needle, and to ensure determining for punching, machinery is complicated, of high cost.And for punching
The fixation and installation of pin, are generally fixed using bolt, and required installation space demand is especially big, or enterprising in red needle
Row is fixed, but stability maintenance is bad, and in the case of multiple rows of red needle, the clearance gap of each red needle is big,
For the especially small component of small-bore and spacing, high-precision punching can not be carried out, it is existing to carry out downsizing design mostly, but
It is that corresponding intensity and tonnage decline, punch work big for thickness but high precision prescribed can not carry out.
The prior art is also correspondingly improved, such as Chinese patent application, application number 201480028822.9, publication date
On January 6th, 2016, a kind of punching machine is disclosed, possess the synthesis punch supporting mass for carrying multiple punches and rushed positioned at the synthesis
The lower section of head supporting body and the comprehensive the moon for being provided with multiple formers that punch process is carried out with the collective effect of foregoing punch
Die support body, foregoing comprehensive former supporting mass are to be disposed with aforesaid plurality of former along the outer rim of the synthesis former supporting mass
Part；There is the synthesis former supporting mass comprehensive former to support phosphor bodies and can keep and the synthesis former supporting mass
Become the discrepancy body gone out at least partially to the state outside foregoing outer rim in the state of the connection of main body；Set on the discrepancy body
It is equipped with multiple formers as the part in the aforesaid plurality of former being arranged on foregoing comprehensive former supporting mass.It passes through mould
The design of tool carries out the setting of multiple rows of red needle, but its for spacing it is big the problem of do not solve still.
Chinese patent application, application number 201620704367.6, publication date on December 14th, 2016, discloses numerical control press
Porous mode structure, including punch holder, punch holder cover board, shaping red needle, stripper and multiple-hole die lower die, the shaping red needle pass through
Punch holder cover board is fixed in punch holder, and shaping red needle is equipped with several, uniform array distribution, and several shaping red needles are divided into several rows,
Difference in height is equipped between adjacent two rows of shaping red needles；Multiple-hole die lower die is arranged on the lower section of punch holder, multiple-hole die lower die and punch
Stripper is equipped between seat, the pilot hole coordinated with shaping red needle is provided with stripper；Multiple-hole die lower die is equipped with rushes with shaping
The die hole that pin coordinates, the top peripheral of die hole are equipped with the ring-shaped step for protruding from mould surface under multiple-hole die；This utility model is in number
Greatly improved work efficiency when processing close rush on control punching machine, and product just can reach quality requirements without subsequently smoothing, greatly
It is big to reduce cost, production efficiency is improved, the stability of product quality is ensure that, is worth promoting.But it is not also solved
The problem of spacing is big, high precision machining, and red needle are replaced inconvenient.
The content of the invention
1. technical problems to be solved
It is big for the clearance gap of each red needle existing in the prior art, it is especially small for small-bore and spacing
Component, can not carry out high-precision punching, the problem of punching machine regulated efficiency is slow, and the present invention provides a kind of quick adjustment high efficiency
Punching machine.It has the punching press quantity that can quickly adjust red needle, and precision is high, and adjustment is fast.
2. technical solution
The purpose of the present invention is achieved through the following technical solutions.
A kind of quick adjustment high efficiency punching machine, including left and right wallboard, top are provided with fuel tank, are additionally provided with workbench, work
Make to set die holder on platform, further include and plurality of rows of red needle is provided with sliding block, plurality of rows of red needle is exempted to change system installed in red needle
On, red needle is exempted to change system to be compressed by punch press platen, and adjustment stop assembly before being provided with sliding block, preceding adjustment stop assembly will
The workpieces processing of workbench compresses.
Further, the red needle, which is exempted to change system, includes upper mold seat, and the upper mold seat is provided with slot upper,
