Abstract
The invention relates to a novel extraction block for a net part and press part machine frame of a paper machine. The extraction block is composed of a left extraction block and a right extraction block which are integrally connected through a connecting frame. According to the novel extraction block for the net part and press part machine frame of the paper machine, the two extraction blocks which are originally positioned and installed on a machine frame flange are integrally connected, a contact area between the extraction block and the machine frame is increased, shock-absorbing capability and bearing capacity are improved, overall stability of the net part and press part machine frame is reinforced, and accelerating yield increase and synergism of the paper machine are guaranteed. Simultaneously, a cast aluminum alloy material is adopted to make the extraction block, the weight of the extraction block is reduced while the strength is guaranteed, and the extraction block is convenient to dismantle.
Description
Technical field
The invention belongs to the paper making equipment technical field, particularly relate to a kind of novel web part of paper machine and press section frame and extract piece out.
Background technology
The wet end of 48,00/,600 4 folded net multi-cylinder white board machines and the extraction piece at press section framework pillar and crossbeam place, it acts on main one is wet end and press section framework pillar and crossbeam to be play connect and the load-bearing effect; The 2nd, the extraction piece is designed to detachable apparatus and is convenient to change forming web.Existing web part of paper machine and press section frame are extracted the structure of piece and installment state out as shown in Figure 3, are to adopt δ 8mm corrosion resistant plate to be welded into the rectangle hollow pipe to make and form, and extract that the employing straight pin positions installation when connecting between piece and the frame flange out.Extract piece out for every group and combined by independent two extraction pieces (left extraction piece and right extraction piece), single extraction piece is of a size of: 300(is long) * 170(is wide) * 300(is high), single extraction piece single face contact area is: 0.0134m
2Extract piece single face gross contact area out for two: 0.0268 m
2Because the contact area of extracting out between piece and the frame is little, it is large to extract the pressure that bears on the block unit area out, therefore causes and extracts the piece less stable out.When paper machine speed is promoted to 600m/min, surface layer and lining frame all have obvious vibration and swing, and especially frame swing in head box place is the most obvious, in addition, core, spacer screen etc. everywhere frame all have in various degree vibration or swing, and the speed-raising of paper feeding machine is increased production and improved productivity and brought very large impact.The piece bearing capacity is little, poor stability causes the wet end frame to produce one of reason of vibrations and dancing exactly and extract out, and therefore, enhancing extraction piece stability increases production and improves productivity for the speed-raising of paper machine and has very actual meaning.
Summary of the invention
Purpose of the present invention just is to overcome the defective of above-mentioned prior art, provides a kind of web part of paper machine of effective improving stability and press section frame to extract piece out.
The technical scheme of taking for achieving the above object is:
A kind of novel web part of paper machine and press section frame are extracted piece out, it is characterized in that this extraction piece is comprised of the left extraction piece that connects into an integral body by link and right extraction piece.
Be provided with brace rod between described left extraction piece and the right extraction piece.
Described left extraction piece, right extraction piece, link and brace rod all adopt cast aluminium alloy material to make.
Novel web part of paper machine of the present invention and press section frame are extracted piece out the two piece extraction pieces of original location and installation on the frame flange are linked into an integrated entity, thereby strengthened the contact area of extracting piece and frame out, damping capaicty and bearing capacity have been strengthened, then strengthened the resistance to overturning of wet end and press section frame, increasing production and improying productivity for the speed-raising of paper machine provides guarantee.Simultaneously, the present invention adopts cast aluminium alloy material to make and extracts piece out, has alleviated the weight of extracting piece out when guaranteeing intensity, is convenient to dismounting.
The extraction piece of extraction piece of the present invention and prior art compares:
The appearance and size that the present invention extracts piece out is: 520(is long) * 300(is wide) * 150(is high), the gross contact area of extracting piece after transforming out is 0.0686m2.Extract the piece contact area before and after transforming out and increase multiple: 0.0686 ÷ 0.0268=2.6 doubly.According to formula P=F/S as can be known, do not consider other factors in the constant situation of frame load, it is constant namely to extract piece load-bearing pressure F out, when contact area increases 2.6 times, extracts the piece bearing capacity after transforming out and be 2.6 times before transforming.
Description of drawings
Fig. 1 is the front view that web part of paper machine of the present invention and press section frame are extracted piece out;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the installation diagram of extracting piece in the prior art out;
Fig. 4 is the installation diagram that the present invention extracts piece out.
The specific embodiment
Web part of paper machine of the present invention and press section frame are extracted piece out and are comprised of the left extraction piece 1 that connects into an integral body by link 4 and right extraction piece 2, also are provided with brace rod 3 between left extraction piece 1 and the right extraction piece 2.Described left extraction piece 1, right extraction piece 2, link 4 and brace rod 3 all adopt cast aluminium alloy material to make.Web part of paper machine of the present invention and press section frame are extracted piece out, and very little is 520(length) * 300(is wide) * the 150(height), it highly is extraction piece of the prior art half, during use, and with two stacks, the same prior art of total height.
Claims (3)
1. a novel web part of paper machine and press section frame are extracted piece out, it is characterized in that this extraction piece is comprised of the left extraction piece (1) and the right extraction piece (2) that connect into an integral body by link (4).
