Abstract
The utility model relates to a mould, in particular to a cold punching mould for punching long tube holes in pattern, which overcomes some defects of the former mould. The utility model provides a mould with the advantages of low cost, high work efficiency and easy operation, and the mould is not easy to be damaged. The utility model adopts the following technical projects: the new mould of the tube punching holes in pattern comprises an upper mould, a lower mould and a connecting rod, wherein, the lower mould and the connecting rod are fixedly connected and are positioned above a workbench; the other end of the connecting rod is fixed on the workbench; the upper mould is provided with a plurality of guide rail locating shafts and punching mould knives; the corresponding position of the lower mould is provided with a plurality of guide rail locating holes and punching mould knife holes.
Description
Technical field
The utility model relates to a kind of mould, is meant especially towards the cold-punching mold of long tube round.
Technical background
In daily production, original washing pipe mould is not suitable for producing because of many shortcomings, as Fig. 1, Fig. 2, shown in Figure 3, the patrix of mould has only punch die cutter 131, and corresponding counterdie (being core) also has only punch die tool bore 231, punch die cutter 231 with move back cinder hole groove 41 and be connected, its core mould is put above workbench with fixedlying connected of connecting rod, sleeve pipe can rise up and down during work, and the other end of connecting rod is fixed on the workbench, with the Position Approximate of control core, plate washer is established on workbench in the core both sides, in when work, because of core in pipe, can only rely on baffle controls core position, both sides, belong to the trackless combination, so edge of a knife position is easy to generate deviation, dislocation is stung mutually, then mold damage.
Summary of the invention
The purpose of this utility model provide a kind of not fragile, cost is low, working (machining) efficiency is high, maneuverable long tube round cold-punching mold.
To achieve these goals, the utility model adopts following technical scheme:
A kind of stamping pipe hole new die includes upper die and lower die and connecting rod, wherein counterdie is fixedlyed connected with connecting rod and is put above workbench, the other end of connecting rod is fixed on the workbench, it is characterized in that described patrix is provided with guide rail locating shaft and punch die cutter, the opposite position of counterdie is provided with guide rail locating hole and punch die tool bore.
The guide rail locating shaft of described patrix is two, the distance between the guide rail locating shaft be the guide rail locating shaft and between its nearest punch die cutter the integral multiple of distance, the length of its middle guide locating shaft is greater than the length of punch die cutter; Guide rail locating hole that counterdie is provided with and punch die tool bore, its degree of depth be respectively more than or equal to the length of corresponding guide rail locating shaft and punch die cutter, is connected with in the lower end of punch die tool bore and moves back the cinder hole groove; Guide rail locating shaft front end in the described patrix is a sharp cone distal in addition.
After adopting said method, the utility model can reach following beneficial effect:
1, directly avoids upper die and lower die to sting mutually, improved the service life of mould greatly.
2, utilize the guide rail locating shaft automatic fine tuning to put in order distance between the workpiece round, make between the workpiece round very little apart from error.
3, the utility model mould improves more than 3 times than the production work efficient of original mould.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Include patrix 1, counterdie 2 and connecting rod 3 as the stamping pipe hole new die in Fig. 4, Fig. 5, the present embodiment shown in Figure 6, wherein counterdie 2 is fixedlyed connected with connecting rod 3 and is put above workbench, the other end of connecting rod 3 is fixed on the workbench 5, patrix 1 is provided with two guide rail locating shafts 11,12 and punch die cutter 13, certainly the punch die cutter 13 in the present embodiment also can be for more than two, counterdie 2 opposite positions are provided with guide rail locating hole 21,22 and punch die tool bore 23, and correspondence also can be for a plurality of.Distance between the guide rail locating shaft 11 and 12 of patrix 1 be guide rail locating shaft 12 and between its nearest punch die cutter 13 distance, certainly the distance between the guide rail locating shaft 11 and 12 also can be the integral multiple of distance between guide rail locating shaft 12 and the punch die cutter 13, and the distance between guide rail locating shaft 12 and the punch die cutter 13 is set by the required distance of round on the long steel pipe.The length that guide rail locating shaft 11 and 12 length are longer than punch die cutter 13, and the front end of the guide rail locating shaft in guide rail locating shaft 11 and 12 is a sharp cone distal.Like this when work, at first guide rail locating shaft 11 and 12 inserts in the corresponding guide rail locating hole 21,22, the guide rail locating shaft of fixedly counterdie, and sharp cone distal can be regulated automatically and treat that punching follows the distance between the punching, and makes punch die cutter 13 and punch die tool bore 23 positions accurate.Be connected with in the lower end of punch die tool bore 23 and move back cinder hole groove 4, slag is easily dropped out.
