Abstract

The utility model discloses a pneumatic clamp bar device, which comprises a biting clamp bar, a tip dragging clamp bar, disc springs and a pressure spring, and is characterized in that the biting clamp bar and the tip dragging clamp bar are respectively provided with a biting airbag (1) and a tip dragging airbag (9); the airbags are inflated for driving to overcome the force of the disc springs, automatic plating is carried out, and the airbags are deflated to bite and tension a printing plate by means of the disc springs and the pressure spring to achieve automatic plating and positioning, so that a requirement of semi-automatic plating of a sheet-fed offset press can be met, the plating is quick and accurate, human factors for manual plate change are eliminated, and the labor intensity of operators is greatly reduced.

Description

Pneumatic clamp bar device

Technical field

The utility model belongs to the offset printing equipment technical field, has to relate to a kind of pneumatic clamp bar device, is a kind of especially be fit to be applied to realize in high speed, the accurate sheet-fed multicolour offset press semi-automatic plate change, device of locing up.

Background technology

Clamp bar is the mechanism that locatees for the forme tensioning on the sheet-fed multicolour offset press, and changing of printing plates has manual plate change and changes plate two types automatically, and manual plate change operation is taken a lot of work, time-consuming, effort; Automatically plate change not only solves quick plate change problem, and can eliminate the human factor of manual plate change, makes adjustment of the printing plate not only rapid but also accurate.Automatically plate change is divided into semi-automatic plate change and full-automatic plate change, and semi-automatic plate change is on central control board, to start the plate change program, and old forme is withdrawn on the plate rack automatically; Operating personnel take the forme of changing away; New forme is placed on the plate rack, starts automatic adjustment of the printing plate program, and forme can get into preceding clamp bar automatically; Automatically the location is fixed the preceding clamp bar of forme automatically with the back clamp bar.There are problems such as complex structure, manufacturing cost is high, mounting or dismounting version efficient is low in existing plate change device.

Summary of the invention

For improving plate change efficient, stability of locing up and reliability reduce labour intensity; The utility model provides a kind of new semi-automatic air bag clamp bar device of locing up, and this apparatus structure is simple, and cost is low and can improve mounting or dismounting version efficient; Eliminate the human factor of manual plate change, improve the overall performance of machine.

The utility model solves the technical scheme that its technical problem adopted: a kind of pneumatic clamp bar device; Comprise the seaming clamp bar, drag tip clamp bar; And dish spring, stage clip; It is characterized in that: the seaming clamp bar with drag tip clamp bar to be respectively equipped with the seaming air bag and drag tip air bag, the inflation of seaming air bag and venting are opened with the seaming clamp bar respectively and are stung tight forme interlock, drag the inflation of tip air bag and venting control to drag tip clamp bar to sting tight and tensioning forme.

Preferred design is: the seaming air bag withstands steel plate; Can heave and jack-up seaming upper clamp bar at the active force lower gasbag of gas pressure intensity; Make the seaming upper clamp bar overcome the dish spring force; Drag tip air bag to promote to drag clamp bar before the tip, slide plate to overcome stage clip elastic force and be close to, drag behind the tip clamp bar to overcome the dish spring force simultaneously and open to the cylinder limit.

The utility model adopts airbag aeration to drive to overcome disc spring force to open automatically to lock up, and air bag deflation relies on dish spring and stage clip to sting tight and the tensioning forme reaches and locks up the location automatically.Promptly on central control board, start the plate change program, old forme is withdrawn on the plate rack automatically, and the operator takes the forme of changing away; New forme is placed on the plate rack, starts automatic adjustment of the printing plate program, and forme can get into preceding clamp bar automatically; Automatically the location is fixed the preceding clamp bar of forme automatically with the back clamp bar.

The beneficial effect of the utility model is, substitute formerly take a lot of work, the manual plate change operation of time-consuming, effort, solve quick plate change problem, and can eliminate the human factor of manual plate change, make adjustment of the printing plate not only rapidly but also accurately.

Description of drawings

Fig. 1 is the utility model installation diagram.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Shown in Fig. 1: 1-seaming air bag, 2-steel plate, 3-axle, 4-dish spring, 5-seaming upper clamp bar, 6-dish spring, 7-drag clamp bar behind the tip, and 8-presses version, and 9-drags tip air bag, and 10-drags clamp bar before the tip, 11-stage clip, 12-slide plate .

In offset press, the basic demand of forme clamp bar device is attached on the plate cylinder with the forme clamping and positioning.Seaming partly gives the seaming air bag 1 inflation among Fig. 1; Heave and jack-up steel plate 2, axle 3 and seaming upper clamp bar 5 at the active force lower gasbag 1 of gas pressure intensity; Making seaming upper clamp bar 5 overcome dish spring 3 elastic force moves; This moment the forme seaming is packed into behind the seaming clamp bar, tight forme is stung in 1 venting of seaming air bag like this under the effect of dish spring 3 elastic force.Drag taper to give and drag 9 inflations of tip air bag; The active force lower gasbag 9 of gas pressure intensity heave promote to drag the tip before clamp bar 10, slide plate 12 overcome stage clip 11 elastic force and be close to the cylinder limit; Drag behind the tip clamp bar 7 to overcome dish spring 6 elastic force simultaneously and open, drag tip air bag 9 venting after forme is dragged the tip to pack into to drag the tip clamp bar this moment; Under the effect of dish spring 6 elastic force, sting tight forme like this, tensioning forme under the stage clip 11 elastic force effects.

Claims

1. pneumatic clamp bar device; Comprise the seaming clamp bar, drag tip clamp bar; And dish spring, stage clip; It is characterized in that: the seaming clamp bar with drag tip clamp bar to be respectively equipped with seaming air bag (1) and drag tip air bag (9), the inflation of seaming air bag (1) and venting are opened with the seaming clamp bar respectively and are stung tight forme interlock, drag inflation and the venting control of tip air bag (9) to drag tip clamp bar to sting and tightly reach the tensioning forme.

2. according to the said pneumatic clamp bar device of claim 1; It is characterized in that: seaming air bag (1) withstands steel plate (2); Drag tip air bag (9) to promote to drag clamp bar (10) before the tip, slide plate (12) to overcome stage clip (11) elastic force and be close to, drag behind the tip clamp bar (7) to overcome dish spring (6) elastic force simultaneously and open to the cylinder limit.
