The improvement structure of three moulds, three stroke screw forming machines

Technical field

The utility model relates to screw forming machine, is meant the improvement structure of three moulds, the three stroke screw forming machines that the relevant position of a kind of abrasion performance and assembling is accurate, firm especially.

Background technology

Common screw forming machine structure, show as Fig. 1 to Fig. 5, it mainly is provided with an accommodation space 101 in a support 10, be arranged with two groups of tool differences of height and horizontally extending first in these accommodation space 101 2 sides, two

conduits

1011,1012, and an end has a main drive rod 102 that is subjected to default drive power source in this accommodation space 101, this main drive rod 102 and outside interlock one first driven wheel 103, and this first driven wheel 103 is except that itself drives a first connecting rod 1031, and synchro-meshing one second driven wheel 104, by this second driven wheel, 104 interlocks, one second connecting rod 1041, one cuts seat 20 is located at side outside support 10 stage casings, its table side central authorities are provided with a charging hole 202 that can supply the strip steel wire to stretch into, being provided with one in cutting seat 20 driven and the cutting knife 201 of past polyslip by aforementioned first connecting rod 1031, so that this strip steel wire is cut to suitable length, and this support 10 in this cut the seat 20 side-lower is provided with a multiple mounted cam 40, this multiple mounted cam 40 has two different peripheral shapes, can drive Rocker arm 4 04 interlock one interlinked mechanism 30 of a tool bifurcated end, and this interlinked mechanism 30 can be located at support 10 tool master drive rods 102 clamping fixture seat 50 of end in addition via a trace 301 interlocks one, cut seat 20 stock that cuts and semi-finished product to drive on this clamping fixture seat 50 default plural anchor clamps clamping is aforementioned respectively by this, and move to next stamping procedure, and a main slide 60 is located in the accommodation space 101 of this support 10, can do toward the polyslip action with respect to this clamping fixture seat 50 by the driving of this main drive rod 102, then be provided with some diels in these main slide 60 front ends, utilize this main slide 60 to drive each mould longitudinally toward polyslip, cooperate the horizontal folder of plural anchor clamps of clamping fixture seat 50 to move this stock and semi-finished product, can form the screw processing and forming mechanism of the many strokes of multi-mould;

Yet said structure has following disappearance:

1. because being arranged at one, this cutting knife 201 cuts past polyslip (showing) in the default conduit 2011 on the seat 20 as Fig. 2, to cut this strip steel wire, but after the permanent friction, the contact-making surface of this cutting knife 201 and conduit 2011 is easy to generate wearing and tearing and becomes flexible, and causes to cut the flimsy situation of the not good parts even of precision.

2. common multiple mounted cam 40 by two independently cam 401,402 run through in conjunction with (as shown in Figure 3, Figure 4) by some bolts 403, it not only has the not good shortcoming of combination precision, and after permanent use, also be subject to external force or vibration effect, and 401,402 generations of this cam are got loose, hinder production and processing.

3. this main slide 60 is connected the main drive rod 102 of this support 10 with a spindle rod 604, and two sides in this main slide 60 are provided with first of two groups of tool differences of height, two flanks 601,602 can correspondingly respectively stretch into first of this support 10, two

conduits

1011,1012, these main slide 60 front then are provided with some for the groove road 603 (as shown in Figure 5) that combines with diel, utilize main drive rod 102 to drive, make this main slide 60 first, two

conduits

1011,1012 bearing of trend slippages, so that the diel on the groove road 603 is reciprocating with respect to clamping fixture seat 50, yet, after permanent the use, vertical contact-making surface 6012 and horizontal contact-making surface 6021 positions, these second flank, 602 bottom sides in this horizontal contact-making surface 6011 in first flank, 601 bottom sides and end side thereof all easily produce wearing and tearing, influence machining accuracy and smooth and easy.

Because common screw forming machine structure has above-mentioned shortcoming, the creator studies improved road at those shortcomings, has the utility model to produce finally.
