Description
Technical field
The present invention relates to punching machine manufacturing fields, exempt to change system and answer more specifically to a kind of multiple rows of red needle of punching machine
With its 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 of less demanding to operator's technology and by various mold 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
Mold 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 mold.
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, mostly 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 control 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, existing most progress downsizing design, 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；It is 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, disclose numerical control press at publication date on December 14th, 2016
Porous mode structure, including punch holder, punch holder cover board, shaping red needle, stripper and multiple-hole die lower die, the shaping red needle passes 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 with shaping red needle cooperation is provided on stripper；Multiple-hole die lower die is equipped with rushes with shaping
The die hole of pin cooperation, 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
It is 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 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 multiple rows of red needles of punching machine to exempt from
It changes system and applies its 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.
Red needle, which exempts to change system, includes upper mold seat, and the upper mold seat is provided with slot, the slot where upper mold seat upper
Position section is L-shaped, and red needle hole is provided on upper mold seat, and the red needle bore dia is up big and down small, and red needle is set through red needle hole
It puts on upper mold seat, further includes movable inserted block, movable inserted block is inserted into corresponding slot position in corresponding red needle operation, on
Die holder is fixed on sliding block, and the corresponding upper mold seat red needle hole site of sliding block is provided with the pin hole that changes the outfit.
Further, the red needle top is up big and down small, is matched with upper mold seat red needle hole shape, lower part is cylinder
Shape.
Further, the socket depth is identical with movable inserted block height.Guarantee will not protrude, and influence work up and down
Make.
Further, below the corresponding red needle hole of the upper mold seat, it is connected with guide post.It can prevent red needle quilt
Damage is hit, ensures the stability and intensity of red needle at work.
A kind of punching machine for exempting to change system including the multiple rows of red needle of punching machine, including left and right wallboard, top is provided with fuel tank, also
