Description
Technical field
The present invention relates to the Panel Bending equipment that boiler water wall in a row bends, particularly relate to a kind of in a row bending machine.
Background technology
Boiler for high power station generally adopts membrane wall to increase heating surface area and to improve overall air-tightness, the water-cooling wall of modern boiler for high power station, the heating surface such as coated generally adopt pipe to add band steel on production line of automatically composing and laying out, are welded into certain tabular film-type tube bank, this is bent into the technique of required membrane wall assembly bend pipe in a row to row, existing market boiler type is various, so also progressively improve the range of work of equipment and the requirement of ability.The bending radius of now main Panel Bending equipment is R200 ~ R420, and it is too small often to there will be film mode tube screen Panel Bending bending radius in actual production, at present, boiler factory is for the excessive water-cooling wall of large diameter thin wall pipe angle of bend, generally can only solve by change bending radius (bending radius is changed greatly) or by increasing elbow, the former makes structure expand, even to change boiler global design, the latter needs to increase welding and flaw detection, obviously turn increase the risk and cost, exceed the situation of bend pipe machined scope in a row, so it is just very necessary to carry out transformation to existing equipment.
Therefore, the problems referred to above should be paid attention to and the problem solved in bending machine design and use process in a row.
Summary of the invention
For above-mentioned Problems existing, the invention provides one and overcome defect of the prior art, provide a kind of rational in infrastructure, the bending machine in a row that quality reaches a standard.
Technical solution of the present invention is: a kind of in a row bending machine, comprise tube panel, Panel Bending machine support and the rotating disk being fixed on described support both sides, be provided with roll bending between described rotating disk and promote roller, described roll bending promotes roller two ends and is arranged on described rotating disk, described roll bending promotes roller and comprises upper roller of press brake and two veneer reeling machine lower rolls, and the bottom of described upper roller of press brake is provided with several Panel Bending moulds simultaneously.
Further improvement of the present invention is: described Panel Bending mould is that downward hydraulic coupling coordinates particular manufacturing craft, has the arc groove die cavity matched with tube panel of several circle be arranged side by side.
Further improvement of the present invention is: have space between described veneer reeling machine lower roll, and the Panel Bending mould of described upper roller of press brake lower end is positioned at directly over described space.
Further improvement of the present invention is: the specification of described Panel Bending mould is unrestricted, can be different size.
Further improvement of the present invention is: described tube panel comprises several pipes connected in a row, is added with parallels between described pipe.
Further improvement of the present invention is: be welded with reinforced seat below described support, and described reinforced seat is fixedly connected with on the ground by several foundation bolts.
A kind of in a row bending machine of the present invention, for preventing the A point place contacted with two veneer reeling machine lower rolls at tube panel, described tube panel is stressed excessive, causes pipe deformation, and therefore tube panel adds parallels between the pipe and pipe at the A point place contacted with two veneer reeling machine lower rolls, improve pipe stressing conditions, improve quality and the precision of pipe bending, by the detection to bend pipe sample, determine the ovality of tube panel crook in a row, wall thickness reduction amount and appearance forming etc. all meet technological requirement, and rear batch bends product.
The invention has the beneficial effects as follows: the invention provides a kind of in a row bending machine, below its support, weld reinforced seat fix on the ground, improve the safety coefficient that it uses, and parallels is added with between the pipe of tube panel, improve stressing conditions stressed in pipe bending process, ensure that quality and the precision of product, the Panel Bending mould of different size also can be set simultaneously, improve the efficiency of production, cost-saving.

Detailed description of the invention
In order to deepen the understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, not forming protection scope of the present invention and limiting.
As shown in the figure, technical solution of the present invention is: a kind of in a row bending machine, comprise tube panel 4, Panel Bending machine support 7 and the rotating disk 8 being fixed on described support both sides, be provided with roll bending between described rotating disk 8 and promote roller, described roll bending promotes roller two ends and is arranged on described rotating disk 8, described roll bending promotes roller and comprises upper roller of press brake 1 and two veneer reeling machine lower rolls 2, the bottom of described upper roller of press brake 1 is provided with the Panel Bending mould 3 of 3 different sizes simultaneously, described Panel Bending mould 3 is that downward hydraulic coupling coordinates particular manufacturing craft, there is the arc groove die cavity 6 matched with tube panel 4 of 2 circles be arranged side by side, space is had between described veneer reeling machine lower roll 2, the Panel Bending mould 3 of described upper roller of press brake 1 lower end is positioned at directly over described space, described tube panel 4 comprises 2 pipes connected in a row, parallels 5 is added with between described pipe, reinforced seat 9 is welded with below described support 7, four angles of described reinforced seat 9 are fixedly connected with on the ground by foundation bolt.
A kind of in a row bending machine of the present invention, for preventing the A point place contacted with two veneer reeling machine lower rolls 2 at tube panel 4, described tube panel 4 is stressed excessive, cause pipe deformation, therefore tube panel 4 adds parallels 5 between the pipe and pipe at the A point place contacted with two veneer reeling machine lower rolls 2, improve pipe stressing conditions, improve quality and the precision of pipe bending, again by the detection to bend pipe sample, determine the ovality of tube panel 4 crook in a row, wall thickness reduction amount and appearance forming etc. all meet technological requirement, and rear batch bends product.
