Abstract
The utility model discloses a vertical multi-connecting-rod toggle rod type movement mechanism of a cold extrusion press. The vertical multi-connecting-rod toggle rod type movement mechanism of the cold extrusion press comprises a bent axle, wherein the bent axle is connected with one end of a main connecting rod, the other end of the main connecting rod is respectively connected with a distance-adjustment connecting rod and a swinging rod, the other end of the distance-adjustment connecting rod is connected with a vertical fixing seat, the other end of the swinging rod is connected with a guide pillar, the guide pillar is arranged in a fixed guide sleeve, the lower end of the guide pillar is connected with a sliding block, and a corner of the bent axle corresponds to the sliding block in position. The vertical multi-connecting-rod toggle rod type movement mechanism of the cold extrusion press has the advantages that the vertical guide pillar and guide sleeve structure is adopted, a lathe is high in accuracy, a machine body is high in rigidity, the sliding block is high in strength and good in guiding performance, and the vertical multi-connecting-rod toggle rod type movement mechanism of the cold extrusion press is favorable for manufacturing high-accuracy products.
Description
Technical field
The utility model belongs to jointed gear unit field, is specifically related to a kind of motion being applied on many link toggle rod types cold extrusion forcing press.
Background technology
Existing to metal stock vertical form processing, more use hydraulic press, when stamping plastic deformation poor, the hard goods quality of extrusion molding is unstable, production efficiency is low, handling safety coefficient is low.This series products of original production is to be solved through Multi-step forming by hydraulic press, and speed of production is slow, and per minute only have 5-10 time, and labour intensity is high, and power consumption is large, inefficiency.
At present, do not have many link toggle rod types motion to be vertically applied to cold extrusion forcing press yet, therefore need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
The utility model technical issues that need to address be to provide a kind of be applied on many link toggle rod types cold extrusion forcing press can be at the motion that vertically metal stock is formed processing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The vertical many link toggle rod types cold extrusion press motion of one mechanism, comprise bent axle, this bent axle is connected with master connecting-rod one end, the master connecting-rod other end is connected with roll adjustment connecting rod and fork respectively, the roll adjustment connecting rod other end is connected with vertical holder, the other end of fork is connected with guide pillar, and guide pillar is placed in fixing guide pin bushing, and guide pillar lower end is connected with slide block.
Slide block is in the time of top dead-centre, and crank angle α is 0 °; When slider row proceeds to crush stroke, crank angle α is 100 ° ~ 104 °; When slider row proceeds to bottom dead centre, crank angle α is 203 ° ~ 204 °; When slide block backhaul, bent axle forwards 360 ° to from 203 ° ~ 204 °.
The utility model has the advantages that: adopt vertical guide pillar guide sleeve structure, machine tool accuracy is high, and fuselage rigidity is high, slide block intensity is large, lead, and is conducive to manufacture high-precision product.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein, 1, bent axle, 2, master connecting-rod, 3, roll adjustment connecting rod, 4, fork, 5, vertical holder, 6, guide pillar, 7, guide pin bushing, 8, slide block, 9, bottom dead centre, 10, top dead-centre, α, corner.
Detailed description of the invention:
The vertical many link toggle rod types cold extrusion press motion of one mechanism, comprise bent axle 1, this bent axle 1 is connected with master connecting-rod 2 one end, master connecting-rod 2 other ends are connected with roll adjustment connecting rod 3 and fork 4 respectively, roll adjustment connecting rod 3 other ends are connected with vertical holder 5, the other end of fork 4 is connected with guide pillar 6, and guide pillar 6 is placed in fixing guide pin bushing 7, and guide pillar 6 lower ends are connected with slide block 8.
After this motion is applied on many link toggle rod types cold extrusion forcing press, the motor of forcing press rotates by belt pulley flywheel driven, and by clutch driven gear pair, bent axle 1 is rotated, the master connecting-rod 2 being connected with bent axle 1 moves immediately, drive roll adjustment connecting rod 3, fork 4 to move, and then under the effect of guide pillar 6, between nominal pressure stroke, keep having the up and down reciprocatingly compressional movement of certain holdup time with movable slider 8.In this reciprocating motion process: slide block 8 is in nominal pressure stroke upper end, and while being also top dead-centre 10, bent axle 1 corner α is 0 °; When slide block 8 marches to crush stroke, bent axle 1 corner α is 102 °; March to crush stroke lower end, while being also bottom dead centre 9, bent axle 1 corner α is 203.6 °, and also, bent axle 1 has turned over 101.6 ° in crush stroke section; When slide block backhaul, bent axle 1 forwards 360 ° to from 203.6 °, turns over 156.4 °.
It is better in vertical guidance quality, also more firm that guide pillar 6 is placed in the interior slide block 8 that can make of fixing guide pin bushing 7, improved the precision of lathe, is convenient to manufacture high-precision product.
