Abstract
The utility model provides an online cold bending type steel secondary punching mould, which belongs to a metal plastic moulding technical field. The punching mould comprises an upper mould and a lower mould. The upper mould and the lower mould adopt a guide post (8) and a guide sleeve (7) to guide. A punching convex mould (4) is fixed on a fixing plate (5) of the convex mould of the upper mould and is fixed on an upper mould seat (6) by the fixing plate of the convex mould. A punching concave mould (3) is fixed on a lower mould seat (1) by a fixing plate (2) of the punching concave mould. When cold bending type steel runs to a small follow-up trolley, a control system makes a positioning claw of a machine positioning device inserted in a pre-punched hole of the cold bending type steel according to signals sent by a photoelectric inductive switch, a hydraulic cylinder drives the upper punching mould to downwards move. After punching operation is completed, the upper mould returns, the positioning claw is drawn out from the pre-punched hole of the cold bending type steel and the small follow-up trolley returns under the action of a resetting cylinder to complete second punching operation. The utility model has the advantages that the utility model guarantees the engagement of the first punching operation and the second punching operation of plate materials, the quality of a punching section is good, the service life of the mould is long and the utility model is convenient to maintain and replace.
Description
Technical field
The invention belongs to the metal plastic forming technical field, a kind of online cold bending steel secondary punch die particularly is provided.
Background technology
On shaped steel, during punching, normally adopt and once directly go out, but the last punching of technology sometimes needs to consider secondary punching when unworkable.Need the new method for die cutting of research like this, match to guarantee plate one-off hole-piercing and shaped steel secondary punch.At present, this technology is domestic does not appear in the newspapers, and has abroad begun to adopt to carry out pre-punched hole one time on strip, enters the make-up machine cold bending subsequently, shaped steel is carried out the new technology of secondary punch thereupon.In this technology, one of effect of a pre-punched hole is to be that the photoelectric sensor switch triggering signal is used when supplying secondary punch; Another effect is to have avoided the once direct thin and undercapacity that causes of punching concave die wall thick mistake of shaped steel.This has just proposed the design of a pre-punched hole and the connection problem of pre-punched hole and secondary punch.
When shaped steel was die-cut, die cutting die was another key technical problem that will solve.Common shaped steel is die-cut, protruding, die shaped design similar with profile shapes, this must make blanking pressure strengthen, the section distortion is big, and subsequent handling can't be carried out, and protruding, the die life-span short.
Summary of the invention
The object of the present invention is to provide a kind of online cold bending steel secondary punch die, it is little to realize that the die-cut high efficiency of online cold-rolled forming section, high position precision, section are out of shape, and die life is long.
Die-cut mould comprises upper die and lower die two parts, and upper and lower mould adopts guide pillar 8, guide pin bushing 7 modes to lead.Die-cut punch 4 is fixed on the die-cut punch retainer 5 of patrix, is fixed on the upper bolster 6 by punch retainer then, and die-cut punch cutting edge is formed by connecting by circular arc and straight line, and arc radius is determined according to processing parts; See Fig. 2.Die-cut die 3 and arranged on left and right sides symmetries are fixed on the die shoe 1 by die-cut die block 2, and the die-cut die of and arranged on left and right sides adopts 4 mold inserts assembled respectively, as shown in Figure 3.
The system that realizes online cold bending steel secondary punch method comprises: pre-punched hole and servo-actuated dolly, reset cylinder, mechanical positioner, photoelectric sensor switch, control system, hydraulic cylinder and die-cut mould.When cold-rolled forming section moves to the servo-actuated dolly, the signal that control system is sent according to photoelectric sensor switch, the locating detent of mechanical positioner is inserted in the pre-punched hole of cold-rolled forming section, cold-rolled forming section drive dolly moves together like this, hydraulic cylinder is according to the signal of control system thereupon, it is descending to drive die-cut patrix, finish die-cut after, patrix returns, and locating detent is extracted from the pre-punched hole of cold-rolled forming section, then under the effect of reset cylinder, the fast return of servo-actuated dolly, finish secondary punch, thereby finish an impulse stroke, begin then to move next time.Can on continuous processing line, finish secondary punch fast like this.
For realizing the quick secondary punch of online cold-rolled forming section, at first the key issue that will solve is the accurate location of shaped steel.When cold-rolled forming section moved to the servo-actuated dolly, the pre-punched hole on it made photoelectric sensor switch send signal and gives control system, and the locating detent of control system control mechanical positioner inserts in the pre-punched hole of cold-rolled forming section then, thereby realized accurately location.
Another key issue that will solve is the design of a pre-punched hole, promptly its size and location is designed.The effect one of pre-punched hole is to be photoelectric sensor switch triggering signal usefulness, the 2nd, cross section deformation when preventing secondary punch.For guaranteeing that pre-punched hole and secondary punch match, guarantee good die-cut section, the centre-to-centre spacing of a pre-punched hole needs to be consistent with the centre-to-centre spacing of secondary punch, and pre-punched hole and secondary punch need have, and 2～4mm's is overlapping.
The invention has the advantages that: the secondary punch technical guarantee plate one-off hole-piercing and shaped steel secondary punch match, the section quality is good, the shaped steel distortion is little, die life is long, is convenient to safeguard and replacing.

The specific embodiment
Online cold bending steel secondary punch method is made up of pre-punched hole and servo-actuated dolly, reset cylinder, mechanical positioner, photoelectric sensor switch, control system, hydraulic cylinder and die-cut mould etc.When cold-rolled forming section moves to the servo-actuated dolly, the signal that control system is sent according to photoelectric sensor switch, the locating detent of mechanical positioner is inserted in the pre-punched hole of shaped steel, shaped steel drive dolly moves together like this, hydraulic cylinder is according to the signal of control system thereupon, it is descending to drive die-cut patrix, finish die-cut after, patrix returns, and locating detent is extracted from the pre-punched hole of cold-rolled forming section, then under the effect of reset cylinder, the fast return of servo-actuated dolly, finish secondary punch, thereby finish an impulse stroke, begin then to move next time.Can onlinely finish secondary punch fast like this.
Die-cut mould comprises upper die and lower die two parts, and upper and lower mould adopts guide pillar 8, guide pin bushing 7 modes to lead.Die-cut punch 4 is fixed on the die-cut punch retainer 5 of patrix, is fixed on the upper bolster 6 by punch retainer then, and die-cut punch cutting edge is formed by connecting by circular arc and straight line, sees Fig. 2; Die-cut die 3 and arranged on left and right sides symmetries are fixed on the die shoe 1 by die-cut die block 2, and the die-cut die of and arranged on left and right sides adopts 4 mold inserts assembled respectively, as shown in Figure 3.
