Description

The hole punched device of bridge plate production line

Technical field

The invention belongs to the equipment of making bridge plate in the engineering construction, particularly be applicable to the hole punched device of a kind of bridge plate production line in the bridge plate production line.Also be applicable to and go out the guardrail product that needs flange behind the hole.

Background technology

As everyone knows, bridge plate is widely used in the middle of the engineering construction, and bridge plate utilizes connecting hole to connect or the assembling use one by one.Need by the engineering project construction, utilize to connect fabrication hole, connector, keel connect, are assembled into vertical or horizontal job space space with certain altitude, length, width with bridge plate.Usually this hole is called connecting hole, the quantity of connecting hole on bridge plate is few, generally is distributed in the place, surrounding of bridge plate, and therefore the connecting hole to every bridge plate just requires to have strict status requirement.Anti-slide opening is the flange hole with flanging process, is called the flange hole again, and its quantity is a lot, concentrates the central authorities be distributed in bridge plate, according to job requirement the height and the tapering of institute's flange is had very high requirement for restriction equally.

At present, the production technology of bridge plate is first punching, back flange.Such production technology, efficient is the end very, dash owing to carrying out secondary simultaneously, align for the second time very difficult, and the punchings used of great majority now touch tool usually produce the not situation of blanking when blankings, dash the waste material that falls and stay on the workbench, cause waste extremely easily, bridge plate has to scrap, and comes economic loss for the production order bit strip.

Summary of the invention

The present invention is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only reasonable in design, compact conformation, can realize punching and flange simultaneously, make the hole of going out have accurate position degree again, and have the production efficiency height, good product quality, labour intensity is low, and handling safety is used a kind of hole punched device of bridge plate production line very easily.

The objective of the invention is to adopt following technical scheme to realize: the hole punched device of described bridge plate production line, it is characterized in that: between the upper table of punching machine and lower table, be connected by vertical, the transition bracket that crossbeam connects to form, in transition bracket, install hole punched device, described hole punched device is by the square box support body, convex template, gusset piece on second, plate, cylinder, stripper and concave template are formed, by gusset piece on first, lower bolster and four movable guide pillars are assembled into the square box support body, described four movable guide pillars distribute and are installed in the interior Si Jiaochu of square box support body, described each movable guide pillar is made up of guide pillar and guide column sleeve, the top of guide column sleeve is vertically connected on the bottom surface of gusset piece on first, an end of movable set guide pillar in the bottom of guide column sleeve, the other end of guide pillar is connected on the end face of lower bolster; Connect gusset piece on second in the square box support body first on the bottom surface of gusset piece, installing convex template in gusset piece bottom surface on second; Be distributed with more than one punch set in the plate face of described convex template; Described each punch set is made up of punch, back-moving spring, spring housing and pressing plate, and described punch is divided into two kinds of the punch in the punch of connecting hole and flange hole; One end of punch is the big footpath of a path section other end section, is provided with shoulder on the section of the big footpath at middle part; The spring housing of packing in the hole of convex template passes behind the suit back-moving spring on the path section of punch in the apical pore that spring housing is socketed in convex template, and makes the circular bead surface of big footpath section concordant with the bottom surface of convex template, pressing plate is fixed on the bottom surface of convex template by screw; The big footpath section of punch is sleeved in the hole of stripper; When adopting the punch in flange hole, its punch middle part shoulder has and required flange hole tapering and the corresponding conical section of tapering height; Be used to lead and the guiding mechanism of discharging function the below installing concave template of stripper more than four being distributed with between convex template and the stripper; Be distributed with one in the described concave template plate face with upper cavity die and the material lift device more than at least four, installing die base plate between concave template and lower bolster; Be provided with a plurality of plates that drive by cylinder in the convex template on convex template and second between the gusset piece.

Described each material lift device is made up of jackscrew, jacking block, limited block, spring and screw mandrel, jacking block is housed in concave template, jacking block is connected by jackscrew with limited block, and an end of screw mandrel places in the locating hole of limited block, the other end is connected in the lower bolster pocketed springs on the stage casing of screw mandrel.It is mainly used to after each working cycles, and punching finishes sheet material is lifted away from the lower bolster surface, and screw mandrel is used for adjusting and lifts power, and limited block and jacking block can be regulated raising height.

Be processed with the gas circuit of vertical, horizontal on the plate face of described die base plate.

Described stripper, corresponding with the punch position of each punch set and size, in the stripper face, be processed with respectively punch can into and out of pass through the hole; Stripper is to be used for after each work, and sheet material and the punch broken through are thrown off, and to prevent the band material, the motion to punch simultaneously play the guiding role, and strengthens the stability of punch, protects punch and improves the punch working condition.

Be provided with backing plate between lower bolster in the described square box support body and the lower table.Its backing plate is used for mould is fixed on the table top of press lower table; Make installation process simple, become in mold exchange more.Prevent also simultaneously that pressure is excessive to mould generation destruction.
