Description
Technical field
The invention belongs to machinery fields, and in particular to the formed punch in a kind of punching die.
Background technique
In the production of interior high-pressure pipe member, some products have hole characteristic, before this, mostly form in pipe fitting by interior Belt-type tools
Afterwards, laser cutting or punching other processes are individually carried out.Technical process is increased, manufacturing cost is improved, position precision is poor.Closely
Although phase has the technical solution of punching simultaneously in forming process to utilize formed punch that is, under the supporting role of liquid in pipe pressure
The hole-punching method that section tubular wall material is separated with pipe fitting.Simplify production procedure, improves efficiency.Such pore-forming technique, in order to keep away
To exempt from blanking and enter molded part to be difficult to clean off, non-circle is mostly used to be punched, blanking part is first folded in lumen, after pipe fitting depanning,
The hole core segment stayed on molded part manually clamps out, and such pore-forming mode, punch head blade oral area partial volume is easy to damage, leads to hole quality
Decline.The quality that can only guarantee punching notch by frequently replacing formed punch, causes Product Process cost to increase.For interior high pressure
Shaped article in previous formed punch, including cooperate with fixture assembly head, cut workpiece cutting edge end, pass through high-pressure molding mold institute
Need the middle part bar of length.Since previous such formed punch assembly head, middle bar, cutting edge section are integral, the sustainable use of when replacement
Position discard together, it is clear that be a kind of waste.Furthermore.Replacement formed punch need to sling mold, and oil cylinder is dismantled below mold, then
Low punch is unloaded, is replaced.It is relatively time-consuming, arduously.
Summary of the invention
The object of the present invention is to provide a kind of interior high-pressure molding punching simultaneously energy part quick change multipart punch, in interior high pressure
It is directly punched out before the pressure release depanning of molded part inner cavity in molding.Overcome the existing waste material of existing synchronous punching formed punch and
Artificial deficiency.
Formed punch of the invention include with formed punch holding clamp cooperation pedestal, on interior high-pressure molding part the cutting edge of punching,
Cylindrical straight bar part between pedestal and cutting edge, wherein pedestal is the cylinder that cross section is in flat-cut round, pedestal cross section
The diameter of circular arc portion is greater 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 formed punch cutting edge end crosses to form flat-cut round cutting edge,
When lateral incision face axial length on straight-bar is fed to stop with formed punch outside the molded part of its tail end still in a mold；Improvements introduced
Be: the formed punch is formed by two sections, forms plug tenon, another section of punching towards the connecting pin of another section of formed punch in wherein one section of formed punch
The corresponding end of head forms tenon mouth, in the opposite end of two sections of formed punches, respectively there is a threaded hole positioned at shaft core position, on two sections of formed punch axle center
Threaded hole in screw thread reverse thread each other, two sections of formed punches connect with the connecting screw of both ends reverse thread each other, even
It connects screw rod and two sections of formed punch axle center threaded holes cooperates, connecting screw is towards having allen wrench insertion on the end face of cutting edge one end
Slot has one section of axle center hole having for being inserted into die nut bar of cutting edge in two sections of formed punches.
To prevent two sections of formed punch group timing cutting edges from overturning in a circumferential direction with pedestal, two and tenon mouth on the plug tenon
The tenon plane Length discrepancy of cooperation, the length of the tenon mouth two sides cell wall equal length with two tenon planes on plug tenon respectively,
For convenience of the docking operation of two sections of formed punches, respectively there is one section of correcting smooth bar part at the connecting screw both ends.
One section of the process that the two sections of connections and replacement of formed punch of the invention have cutting edge is: by plug tenon plane and tenon mouth wall
Corresponding relationship is opposite by two sections of formed punches, by be inserted into threaded hole connecting screw correcting smooth bar part by two sections of formed punches to just,
It is inserted into die nut from the cutting edge end of formed punch, connecting screw is tightened, maintains the assembling of solid punch.When cutting edge wear and tear overrun needs
When replacement, it is inserted into die nut from cutting edge end, rotation send connecting screw, one section that the formed punch scrapped has cutting edge removed, as at the beginning of formed punch
Begin two sections of Connection Steps, and what is more renewed has a Duan Chongtou of cutting edge.
The positive effect of the present invention is: passing through the formed punch segmentation and segmentation on the whole of punching simultaneously in internal high-pressure molding
The design of connection structure afterwards realizes easy, the quick replacement of the very fast abrading section of formed punch, alleviates the personnel of formed punch replacement
Workload shortens the time shut down because replacing formed punch, improves production efficiency, and what is scrapped is only a part of entire formed punch,
The one end for enabling formed punch to have pedestal is used for a long time, and is reduced the consumption of formed punch material, is advantageously reduced production cost.
