Description
Technical field
The invention belongs to mechanical manufacturing field, inwall heating aspect when relating to barrel soldering.
Background technology
During barrel soldering, inwall needs preheating, and need control interlayer temperature during welding, postwelding needs after-baking, and majority needs to heat frock.At present, adopt in the welding of cylindrical shell peak during welding Circumferential Welds In Cylinders, cylindrical shell bottommost heats.Because girth welding adopts automatic welding, welding position is positioned at cylindrical shell top all the time.Start to welding from heating, cylindrical shell need be rotated to top by cylindrical shell bottommost on turntable, and the temperature section that heats in the process dissipates, and causes preheating, after heat equitemperature parameter can not meet welding process requirement.Therefore series of problems is caused, as weld seam cracks, affects the degree of hardening etc.This problem is insoluble technical problem in welding field actual production process always.
Summary of the invention
Technical problem to be solved in the utility model is interlayer temperature when ensureing the preheat temperature before barrel soldering, welding, postwelding postheat temperature parameter meets welding process requirement.
This patent devises a kind of Circumferential Welds In Cylinders welding inwall heating frock, and its structure is containing top appendix 1, several heating tubes 2, appendix connecting plate 3, air inlet pipe 4, height regulating rod 5, securing member 6, cross bar 7, bottom support bar 8, dolly connecting plate 9, two bottom dolly 10, fixed bar 11 and connecting plate 12; Circumferential Welds In Cylinders center is aimed at dolly center, bottom, and two bottom dollies 10 are connected, fix with connecting plate 12 by bottom fixed bar 11; Bottom dolly 10 forms fixed triangle shape structure with bottom support bar 8; Height regulating rod 5 and bottom support bar 8 adopt securing member to be fixed; On height regulating rod 5, the position of pin-and-hole makes top air delivery device to comparatively suitable position; The spacing that heating tube and cylinder inboard wall heat position is moderate.
Owing to adopting multiple triangular structure to ensure Stability Analysis of Structures in this heating frock; Between this frock interconnect, the securing members such as bearing pin that adopt are fixed, connect more in addition, and therefore this frock is convenient to dismounting and carrying.Use this frock can heat at the cylinder inboard wall of different-diameter, ensure that the heating position of cylindrical shell during welding is in welding position, when control weld preheating temperature, welding, interlayer temperature and weldering postheat temperature produce a desired effect, and decrease the defects such as bead crack; Equipment is detachable, simple to operate, easy to use; Shorten the time that heating position goes to welding portion, avoid heat loss, decrease energy resource consumption.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Circumferential Welds In Cylinders welding inwall heating frock, its structure is containing top appendix 1, several heating tubes 2, appendix connecting plate 3, air inlet pipe 4, height regulating rod 5, securing member 6, cross bar 7, bottom support bar 8, dolly connecting plate 9, two bottom dolly 10, fixed bar 11 and connecting plate 12; In-site installation during use, after this frock parts are put into cylindrical shell one by one, assemble according to shown in Fig. 1 in inner barrel, concrete assembling mode is as follows:
First, as shown in Figure 2, determine that in Circumferential Welds In Cylinders position bottom dolly 10 is span centre positions, use fixed bar 11 and connecting plate 12 to be fixed by dolly bottom two pieces and be connected.Owing to defining triangular structure between bottom dolly, bottom dolly jockey and bottom support bar, therefore ensure that the stability of connection.
Secondly, heating tube 2 and top appendix 1, to top heating tube device, are grouping, fix by group piece by piece.Distance between heating tube and cylinder inboard wall does not temporarily adjust, and adjusts spacing until frock group again after completing.
3rd, group, to bracing or strutting arrangement, adopts securing member bottom dolly 10 and bottom support bar 8 to be carried out being connected, fixing; Then press shown in Fig. 3, adopt securing member to be fixed on height regulating rod 5 and bottom support bar 8, what adopt due to height regulating rod 5 and bottom support bar 8 is that two pieces securing member is connected, and can stop top heater rotation; Cross bar 7 and appendix connecting plate 3 are carried out be connected, fixation;
Finally, cross bar 7 and height regulating rod 5 are grouping, use securing member fixation, during group pair, should ensure that bottom position is constant.By regulating heating tube 2 and the spacing of cylinder inboard wall, making heating tube reach best to the distance at cylinder inboard wall heating position, then connecting air inlet pipe 4, install rear logical upper combustion gas and get final product combustion heating.
Cylindrical shell, in the process of rotating, should be observed bottom dolly in good time and whether in running, produce offset deviation.Along with the rotation of product cylindrical shell on positioner, dolly can remain on cylinder inboard wall least significant end due to deadweight, should without obvious displacement.
After finishing using, each parts are dismantled in accordance with the order from top to bottom one by one.
