Description
Technical field
The utility model is related to full-automatic computer knives bending machine technical field, on a kind of specifically disclosed full-automatic computer knives bending machine
Mo(u)ld bottom half double lead-screw feeding structure.
Background technology
Electronics, printing packaging industry are developed rapidly now, as its supporting industry --- die cutting plate (cutting die) processing industry
Very big development is obtained.And knives bending machine is used as one of two big nucleus equipments in cutting die production, the efficiency and essence processed to cutting die
Degree plays very important effect.The full-automatic computer knives bending machine for growing up for nearest 2 years is more omitted many troubles, only
Parameter is set, computer manipulation is more convenient, simple.
Full-automatic computer knives bending machine typically can disposably complete feeding, bending, shearing, bridge location, olecranon, the work(such as fluting
Can, generally comprise the parts such as feed system, bridge location, olecranon, truncation system, bending system, edging (fluting) system.Prior art
In, there is more research on each structure member.Such as：Patent CN104889202A discloses a kind of knives bending machine with greatly
Angle bent blade device and knives bending machine, patent CN104889229A disclose a kind of knives bending machine serrated knife die cutting die structure and tulwar
Machine, patent CN104889857A discloses a kind of knives bending machine Multifunctional two sides edging device, knives bending machine and edging method.
It is relatively advanced at present to there is patent CN204724744U to disclose for the research of full-automatic computer knives bending machine feeding structure
A kind of computer automatic rule bender feed mechanism, it includes：Supporting table, be fixedly installed in the supporting table for accommodating
Die-cutting rule and make die-cutting rule be in straight panel shape receiving block, be arranged on the clamping for clamping die-cutting rule in the supporting table
Device, the release for controlling the clamping device being arranged on the clamping device and the adjusting means of clamping, Yi Jishe
The drive device being connected with the clamping device in the supporting table is put, the drive device drives the clamping device along institute
The length direction for stating receiving block moves linearly.It uses forward and backward leading screw to drive clamping device, and simple structure can reliable, stabilization
Die-cutting rule is moved on ground forwards.
Because the patent drives the upper of gripping apparatus grips die-cutting rule (i.e. band) using two leading screws of forward and backward setting
Portion travels forward, and the bottom of its die-cutting rule must set the gap (track) of guiding die-cutting rule movement, the height of the vertical plate of both sides
Degree must be less than the height of die-cutting rule, there is following problem：
1st, the feeding stroke of above-mentioned patent feeding structure is more long, and machining accuracy is poor.Using two leading screws of forward and backward setting
The structure of clamping device is driven, the clamping movement distance of die-cutting rule is naturally larger than two sections of length of leading screw, its stroke is more long, and
Can apply larger vertical impact power when die-cutting rule bending, shearing, bridge location, olecranon, fluting etc. are processed to act on die-cutting rule,
The somewhat shake skew of die-cutting rule porch can progressively amplify as stroke increases, so that the precision that die-cutting rule is processed is influenceed,
Feeding stroke is more long, and machining accuracy is poorer.
2nd, the altitude range of the die-cutting rule that above-mentioned patent feeding structure can be matched is limited, it is difficult to the mould of compatible different height
The feeding of cutting knife.Need the height of the die-cutting rule of processing general in 6-32mm, and in above-mentioned patent feeding structure both sides it is vertical
The height of plate must be less than the height of die-cutting rule, and the position of the difference of both height can be used for hitch feed.If above-mentioned patent
Feeding structure needs the feeding of the die-cutting rule of compatibility 6mm or so, then the height of the vertical plate of both sides should be arranged on a 2-3mm left sides
It is right.So, by the way of the driving of forward and backward leading screw track will necessarily be brought more long, and track is long, and play track guide effect
Vertical plate it is highly relatively low, this is easy for causing feeding die-cutting rule easy abjection (custom from gap (track) when quick mobile
Claim " derailing " phenomenon), cause to shut down, cause the discontinuous of processing.
