Abstract
The utility model relates to a novel extraction block for a net part and squeezing part rack of a paper machine. The novel extraction block is composed of a left extraction block body and a right extraction block body, wherein the left extraction block body and the right extraction block body are connected through a connecting frame to form a whole. According to the novel extraction block for the net part and squeezing part rack of the paper machine, due to the fact that original two extraction blocks which are mounted on a rack flange in a positioning mode are connected into a whole, the contact area between the extraction block and the rack is enlarged, the shock absorption capability and bearing capability are enhanced, the overall stability of the net part and squeezing part rack is further enhanced, and a guarantee is provided for speed rise, production increase and efficiency improvement. Meanwhile, the novel extraction block is made of cast aluminum alloy materials, therefore, the weight of the novel extraction block is reduced while the strength is ensured, and the novel extraction block is convenient to dismantle.
Description
Technical field
The utility model belongs to the paper making equipment technical field, particularly relates to a kind of novel web part of paper machine and press section frame and extracts piece out.
Background technology
The wet end of 4800/600 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 that wet end and press section framework pillar and crossbeam are play and 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 between piece and frame flange employing straight pin while connecting out and position installation.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
2; Extract piece single face gross contact area: 0.0268m out for two
2.Because the contact area of extracting out between piece and frame is little, extract the pressure born on the block unit area out large, therefore cause and extract 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, frame such as core, spacer screen etc. everywhere all have vibration or swing in various degree, and the speed-raising of paper feeding machine is increased production and improved productivity and brought very large impact.And extract out, the piece bearing capacity is little, poor stability causes the wet end frame to produce one of reason of vibrations and dancing exactly, therefore, strengthens extraction piece stability and increases production and improves productivity and have very actual meaning for the speed-raising of paper machine.
Summary of the invention
The purpose of this utility model just is to overcome the defect 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 taked 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 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 utility model and press section frame are extracted piece out, and by original location and installation, the extraction of two on frame flange piece links 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, for the speed-raising of paper machine, increased production and improved productivity guarantee is provided.Simultaneously, the utility model 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 utility model and prior art compares:
The appearance and size that the utility model is extracted piece out is: 520(is long) * 300(is wide) * 150(is high), the gross contact area of extracting piece after transformation out is 0.0686m2.Extract the piece contact area before and after transformation out and increase multiple: 0.0686 ÷ 0.0268=2.6 doubly.According to formula, P=F/S is known, does not consider other factors in the situation that the frame load is constant, extracts piece load-bearing pressure F out constant, and when contact area increases 2.6 times, extracting the piece bearing capacity after transformation out is 2.6 times before transformation.
The accompanying drawing explanation
Fig. 1 is the front view that the utility model web part of paper machine and press section frame are extracted piece out;
The top view that Fig. 2 is Fig. 1;
Fig. 3 extracts the installation diagram of piece out in prior art;
Fig. 4 is the installation diagram that the utility model is extracted piece out.
The specific embodiment
The utility model web part of paper machine 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, between left extraction piece 1 and right extraction piece 2, also are provided with brace rod 3.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 utility model and press section frame are extracted piece out, are of a size of 520(long) * 300(is wide) * 150(is high), it is highly extraction piece of the prior art half, during use, by two stacks, total height is with existing technology.
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).
