Description
Technical field
The utility model belongs to machinery field, and in particular to the punch in a kind of punching die.
Background technology
Interior high-pressure pipe member production in, some products carry hole characteristic, before this, mostly pipe fitting pass through interior Belt-type tools into
After type, individually it is cut by laser or punching other processes.Technical process is added, improves manufacture cost, positional precision is poor.
Although there is the technical solution of punching at the same time in forming process in the recent period, i.e., under the supporting role of liquid in pipe pressure, utilize punching
Head is by section tubular wall material hole-punching method separated with pipe fitting.Simplify production procedure, improve efficiency.Such a pore-forming technique, in order to
Avoid blanking from being difficult to clean off into molded part, be punched more using non-circle, blanking part is first folded in tube chamber, pipe fitting depanning
Afterwards, the hole core segment stayed on molded part manually clamps out, and such a pore-forming mode, punch head blade oral area partial volume is fragile, causes pore-forming
Quality declines.It can only ensure the quality of punching notch by frequently replacing punch, cause Product Process cost to increase.For interior
High-pressure molding product in conventional punch, including coordinate with fixture assembly head, cut the cutting edge end of workpiece, through high-pressure molding mould
The middle part bar of length needed for tool.Since conventional such a punch assembly head, middle bar, cutting edge section are integral, when replacement, is sustainable
The position used is discarded in the lump, it is clear that is a kind of waste.In addition.Mould need to be sling by replacing punch, and oil is dismantled below mould
Cylinder, then low punch is unloaded, replaced.It is relatively time-consuming, arduously.
Utility model content
The purpose of this utility model is to provide a kind of interior high-pressure molding energy of punching at the same time part quick change multipart punch, is used for
Directly it is punched out before the pressure release depanning of molded part inner cavity in interior high-pressure molding.Overcome unrestrained existing for existing synchronous punching punch
Take material and artificial deficiency.
The punch of the utility model include with punch holding clamp coordinate base, on interior high-pressure molding part punching sword
Cylindrical straight bar part between mouth, base and cutting edge, wherein, base is the cylinder that cross section is in flat-cut toroidal, and base is horizontal
The diameter of section circular arc portion is more than the diameter of straight bar part, and the length of straight-bar is determined according to the mold wall thickness at molded part punching,
Cutting edge line is the shape of flat-cut circle, and the end face in lateral incision face and straight-bar on the straight-bar of punch cutting edge end crosses to form flat-cut toroidal sword
Mouthful, when the lateral incision face axial length on straight-bar is fed to stop with punch outside the molded part of its tail end still in a mold；Made
Improvement is：The punch is formed by two sections, and one section of punch forms plug tenon towards the connecting pin of another section of punch wherein, another
The corresponding end of Duan Chongtou forms tenon mouth, in the opposite end of two sections of punches, respectively there is the threaded hole positioned at shaft core position, two sections of punch axis
The reverse thread each other of the screw thread in threaded hole in the heart, two sections of punches are connected with the connecting screw of both ends reverse thread each other
Connect, connecting screw and two sections of punch axle center threaded holes coordinate, and connecting screw is towards having allen wrench on the end face of cutting edge one end
Insertion groove, have cutting edge in two sections of punches one section are useful for the axle center hole of insertion die nut bar.
Cutting edge overturns in a circumferential direction with base during to prevent that two sections of punches from assembling, two and tenon mouth on the plug tenon
The tenon plane Length discrepancy of cooperation, the length of the tenon mouth both sides cell wall equal length with two tenon planes on plug tenon respectively,
For convenience of the docking operation of two sections of punches, respectively there is one section of correcting smooth bar part at the connecting screw both ends.
Two sections of the punch of the utility model connect and replace one section of process for having cutting edge：By plug tenon plane and tenon mouth
The correspondence of wall is opposite by two sections of punches, by be inserted into threaded hole connecting screw correcting smooth bar part by two sections of punches pair
Just, die nut is inserted into from the cutting edge end of punch, tightens connecting screw, maintain the assembling of solid punch.When cutting edge wear and tear overrun
When needing replacing, die nut is inserted into from cutting edge end, connecting screw is sent in rotation, and removing the punch scrapped has one section of cutting edge, by punching
Initial two sections of Connection Steps, what is more renewed has one section of punch of cutting edge.
The good effect of the utility model is：By the punch segmentation on the whole of punching at the same time in internal high-pressure molding and
The design of connection structure after segmentation, realizes easy, the quick replacement of the very fast abrading section of punch, alleviates punch replacement
Person works measure, and shorten the time shut down because replacing punch, improve production efficiency, and that scrap is only one of whole punch
Point, one end that enabling punch has base uses for a long time, reduces the consumption of punch material, advantageously reduces production cost.
