Abstract
The utility model relates to an air-actuated upper knocking-out structure with built-in sliding block, which belongs to the field of press machine technique, and the principal characteristics are that the sliding block in the sliding block inner cavity is fixed with several high-pressure nitrogen spring cylinders. The utility model is the original large-sized closed type press machine air-actuated upper knocking-out with optimized improvement, and the original common air compression air cylinder is changed into a spring cylinder with high-pressure nitrogen spring, thereby considerably saving raw material after improvement, and reducing a lot of air pipes because the high-pressure nitrogen spring cylinder does not need exterior gas source, and achieving purpose for reducing the cost, effectively reducing installation spacing because of using high-pressure nitrogen spring mechanism, and saving cost.
Description
Technical field
The utility model relates to the built-in pneumatic dnockout structure that goes up of a kind of slide block, belongs to the press technologies field.
Background technology
Pneumatic filling device is convenient to regulate dnockout power and dnockout stroke, and manipulator easy to use has been created condition for realizing mechanization and automation.Therefore along with pneumatic the universal of dnockout of going up, especially to large-scale straight side press, increasing customer requirement adopts the pneumatic dnockout of going up.But pneumatic dnockout structure more complicated generally is provided with common cylinder at present in slide block, when adopting common cylinder, often is subjected to the restriction of appearance and size and air pressure size, is not reaching needed dnockout power in indivedual Sheet Metal Forming Technologies.For example: a dnockout power is 5T, and stroke is the cylinder of 150mm, and piston diameter reaches φ 430mm, and appearance and size has reached φ 520mm, if the last dnockout power of 500T forcing press must reach 50T, just must adopt 10 above-mentioned cylinders.This shows, adopt common pneumatic dnockout cylinder, then need very big space to install, must strengthen the volume and weight of slide block, increased cost virtually, and also have corresponding many air pipes.
The utility model content
The purpose of this utility model provides the built-in pneumatic dnockout structure that goes up of a kind of slide block, what adopt common cylinder existence in the existing slide block of solution is the specification requirement of satisfying dnockout power, must strengthen the deficiency of the volume and weight of slide block, effectively utilize installing space by the utility model, dwindle the slide block volume, thereby help saving cost.
The purpose of this utility model is achieved through the following technical solutions, and the built-in pneumatic dnockout structure that goes up of a kind of slide block comprises slide block, it is characterized in that, fixes some high pressure nitrogen spring cylinders on the slide plate of slide block inner chamber.
The utility model is that the pneumatic dnockout of going up of original large-scale straight side press is optimized improvement, change original normal air compression cylinder into employing high pressure nitrogen spring cylinder, saved raw-material use after improving greatly, and the high pressure nitrogen spring cylinder does not need external source of the gas, reduce a lot of air pipes, reached the purpose that reduces cost, adopted the high pressure nitrogen spring assembly, effectively dwindle installing space, saved cost.
Description of drawings
Fig. 1 is the utility model sectional structure schematic diagram:
Fig. 2 is fixed on plan structure schematic diagram on the slide plate for some high pressure nitrogen springs in the utility model:
Among the figure, 1 slide block, 2 slide plates, 3 high pressure nitrogen springs.
The specific embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the utility model comprises slide block 1, fixes some high pressure nitrogen spring cylinders 3 on the slide plate 2 of slide block 1 inner chamber.As adopt existing common cylinder in slide block 1, a dnockout power is 5T, and stroke is that the cylinder piston diameter of 150mm reaches φ 430mm, and appearance and size has reached φ 520mm; After adopting high pressure nitrogen spring cylinder 3, its diameter that ejects piston has only φ 65, and appearance and size has only φ 198mm.If the last dnockout power of 500T forcing press must reach 50T, adopt 10 above-mentioned cylinders.Both compare, and adopt common pneumatic dnockout cylinder, then need very big space to install, and just must strengthen the volume and weight of slide block, have increased cost virtually.Adopt the nitrogen spring cylinder then to need very little installing space just can meet the demands.
