Description
Technical field
The utility model is related to die apparatus technical fields, more particularly to a kind of fixing device for punch-pin.
Background technology
At present in machinery manufacturing industry, especially mold manufacturing, in some diels, current punching die structure
In, punch-pin is generally fixed in clamping plate, higher to clamping plate, stripper plate and 3 pieces of mainboard requirement on machining accuracy of lower template, and clamping plate
Hole, de- material plate hole and lower die plate hole are also required to keep accurate correspondence, if machining accuracy is inadequate, clamping plate hole site has partially
Difference cannot install punch-pin, generally require to carry out secondary operation or repair, under serious situation, need that mold is caused to be opened again
Mould is processed, and production cost is higher, and working efficiency is low, has certain limitation.
Utility model content
The main purpose of the utility model is to provide a kind of fixing devices for punch-pin, can effectively solve background skill
The problems in art.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of fixing device for punch-pin, including mounting plate, backing plate and clamping plate, the backing plate are connected in mounting plate and folder
Between plate, mounting hole is offered in the middle part of the mounting plate, and via is offered in the middle part of the backing plate, is opened in the middle part of the clamping plate
Equipped with regulating tank, bushing is connected in the middle part of the regulating tank, running through between the mounting hole and via has bolt, the bushing
Middle part offer annular groove and punch-pin and fix and be clamped, the top middle portion of the punch-pin offers link slot.
Wherein, it is overlapped mutually between the mounting plate, backing plate and clamping plate, and seamless applying.
Wherein, the diameter of the bolt end head nut is more than the diameter of via, bar portion and the via mistake in the bolt stage casing
Cross cooperation.
Wherein, the inner wall of the link slot offers internal thread and is mutually screwed on bolt.
Wherein, the central axes of the mounting hole, via and link slot are on same straight line.
Wherein, the gap location of the regulating tank and bushing is filled with epoxy resin.
Compared with prior art, the utility model has the advantages that：This kind of utility model reasonable design, user
Just, by being provided with bushing in regulating tank, and it is filled with epoxy resin in the gap location of regulating tank and bushing, can had thus
Effect carries out position adjusting to punch-pin, to solve plywood hole, de- material plate hole and lower die plate hole need that the corresponding of precision is kept to close
System, if machining accuracy is inadequate, there is the problem of deviation cannot install punch-pin in clamping plate hole site, improves previous punch-pin installation
Mode does not require the hole of punch-pin clamping plate and stripper plate and lower die plate hole position to have accurate correspondence, can ensure that punch-pin is installed
After mold smooth, gap uniformity, be also avoided that mold carries out secondary operation and the problem of repair a die, effectively reduces mold die sinking
Use cost, and the efficiency of mold manufacturing is improved, and improve the quality of mold production, it is seen that this kind of utility model, function
Practicality is suitble to be widely popularized.

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figure 1, a kind of fixing device for punch-pin, including mounting plate 1, backing plate 3 and clamping plate 6, the backing plate 3 block
It is connected between mounting plate 1 and clamping plate 6, the middle part of the mounting plate 1 offers mounting hole 8, and the middle part of the backing plate 3 offered
The middle part in hole 9, the clamping plate 6 offers regulating tank 5, and the middle part of the regulating tank 5 is connected with bushing 4, the mounting hole 8 and mistake
Through there is bolt 2 between hole 9, the middle part of the bushing 4 offers annular groove and punch-pin 7 is fixed and is clamped, the top of the punch-pin 7
Middle part offers link slot 10, can effectively be fixed thus to punch-pin 7.
Further, it is overlapped mutually between the mounting plate 1, backing plate 3 and clamping plate 6, and seamless applying.
Further, the diameter of 2 top nut of the bolt be more than via 9 diameter, the bar portion in 2 stage casing of the bolt with
9 transition of via coordinates, and prevents bolt 2 from slipping, also allows for the dismounting of mold.
Further, the inner wall of the link slot 10 offers internal thread and is screwed on 2 phase of bolt, keeps bolt 2 effective
Be fixedly connected with punch-pin 7.
Further, the central axes of the mounting hole 8, via 9 and link slot 10 further increase on same straight line
Assembly precision.
Further, the regulating tank 5 and the gap location of bushing 4 are filled with epoxy resin, realize the position tune to punch-pin 7
Section.
It should be noted that the utility model is a kind of fixing device for punch-pin, when use, first will press punch-pin 7
Enter to have in the bushing 4 of annular groove, then bushing 4 is navigated to in gap location filled with epoxy resin the regulating tank 4 in clamping plate 6
In, because the interstitial site between bushing 4 and regulating tank 5 is adjustable, the position of punch-pin 7 can be arbitrarily adjusted thus, even if mould
Corresponding hole glances off in tool, and position correction can be also carried out to punch-pin 7, and last need to be by bolt 2 and 10 screw thread of link slot
Connection, makes punch-pin 7 be fixed on backing plate 3.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
