Abstract
The invention discloses a process for machining a spiral staircase stone cover plate. The process comprises the following steps of: machining a cuboid blank through steps of corner cutting, arc finishing, coping and the like to obtain standard cover plate pieces, and splicing and assembling a plurality of standard cover plate pieces to form a guardrail cover plate. The cover plate machined by the process is precise and standard, the cover plates at different mounting positions can be flexibility exchanged, the cover plates are not required to be wholly spliced, the surface on the spliced guardrail is a smooth curved surface, the splicing effect is good, and mass production is conveniently performed. In addition, the specification of the blank required by the machining process is close to that of the machined cover plate, the machining process is simple, the workload is greatly reduced, lots of stones can be saved, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of processing of stone technique, refer to a kind of processing technology of stone cover plate of spiral stairs guardrail especially.
Background technology
Screw type stone rotary stair is comparatively common in life.The guardrail of stone stairs comprises cover plate more and supports the side plate of cover plate, this cover plate is three arc maintenance plates, the preparation of this cover plate of existing techniques in realizing is generally following two kinds of modes: mode one, and carry out reconditioning seriatim to some cover plate assemblies at the construction field (site), the reconditioning through several times is spliced; Mode two, is divided into some triangle dimension boards by cover plate, some triangle dimension board mosaic splicings of unified processing become cover plate; When stairway specifications is larger, be spliced into cover plate by some rectangular panel.The processing technology of mode one also exists workload greatly, the shortcomings such as machining accuracy is poor, and the process-cycle is long, and splicing effect is undesirable; The processing technology of mode two also exists material consumption amount greatly, and lid surface is difficult to form the shortcomings such as shiny surface.
Summary of the invention
The invention provides a kind of spiral staircase stone cover plate processing technology, large to overcome the workload existed in prior art, the problems such as material consumption is many, and splicing effect is undesirable.
The present invention adopts following technical scheme:
Spiral staircase stone cover plate processing technology, comprises following processing step:
A. prepare: the size of the cover plate machined as required, calculates the length L of required cuboid stone material, width W, thickness H, prepare cuboid blank;
B. corner cut: described cuboid blank width W vertical table-board is located and is positioned on board, cutting knife knife face vertical table-board ground and be two ends in cutting blank length L direction, angle theta ground with the end face in charge length L direction, the cut surface of two ends is parallel to each other, distance and the cos θ c of two cut surfaces match, and c is the length of the blank after corner cut;
C. arc is repaiied: the upper surface template making cover plate upper surface; The side in the thickness H direction of the blank machined in step b according to upper surface template draws the setting-out of cover plate upper surface, cutting knife knife face vertical table-board ground and repair except blank redundance along the setting-out of cover plate upper surface with being parallel to described cut surface;
D. reconditioning: the left and right side face die plate making two sides, cover plate width W direction; The left and right side of the blank machined in step c respectively according to left and right side face die plate draws the left and right side setting-out of cover plate, setting-out corresponding points in left and right side are connected with setting-out on cut surface described in step b, left and right side setting-out is connected with setting-out on cut surface the real contour line namely forming cover plate, take real contour line as the processing that namely the worn redundance of benchmark completes cover plate, the section of the cover plate machined is T font.
From the above-mentioned description to structure of the present invention, compared to the prior art, tool of the present invention has the following advantages: the more accurate and standardization of the specification of the cover plate that this processes obtains, the cover plate of different installation site can be exchanged flexibly, overall examination is not needed to spell, and the guardrail upper surface spliced is smooth surface, splicing effect is good, is also convenient to produce in batches; In addition, the specification of the blank needed for this processing technology is more close to the specification of the cover plate machined, and processing technology not only comparatively simple, workload significantly reduces, and can save a large amount of stone materials, reduces production cost.

Detailed description of the invention
With reference to the accompanying drawings the specific embodiment of the present invention is described.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, spiral staircase stone cover plate processing technology, comprises following processing step:
A. prepare: the size of the cover plate 3 machined as required, calculates the length L of required cuboid stone material, width W, thickness H, prepare cuboid blank 1;
B. corner cut: described cuboid blank 1 width W vertical table-board is located and is positioned on board, the cutting knife 2 knife face vertical table-board ground of slab cutting machine and be two ends in cutting blank 1 length L direction, angle theta ground with the end face in blank 1 length L direction, the angle of inclination of angle theta and cover plate 3 matches; The cut surface 21 of two ends is parallel to each other, and distance and the cos θ c of two cut surfaces 21 match, and c is the length of the blank 1 after corner cut;
C. arc is repaiied: the upper surface template 4 making cover plate 3 upper surface; The side in the thickness H direction of the blank 1 machined in step b according to upper surface template draws the setting-out of cover plate 3 upper surface, the cutting knife 2 knife face vertical table-board ground of slab cutting machine and be parallel to described cut surface 21 ground and repair except blank 1 redundance along the setting-out of cover plate 3 upper surface; This step also can by Jie's line machine realize blank 1 repair arc processing;
D. reconditioning: the left surface template 5a, the right flank template 5b that make two sides, cover plate 3 width W direction; The left and right side of the blank 1 machined in step c respectively according to left surface template 5a, right flank template 5b draws the left and right side setting-out of cover plate 3, setting-out corresponding points in left and right side are connected with setting-out on cut surface 21 described in step b, left and right side setting-out is connected the real contour line namely forming cover plate 3 with setting-out on cut surface 21, take real contour line as the processing that namely the worn redundance of benchmark completes cover plate 3, as shown in Figure 5, the seamed edge of cover plate 3 makes Passivation Treatment; In addition, in order to reduce reconditioning work, reduce the amount of labour and production cost, strengthen the anti-shear ability of cover plate 3, the section of the cover plate 3 machined is T font.
The more accurate and standardization of the specification of the cover plate 3 that this processes obtains, the cover plate 3 of different installation site can be exchanged flexibly, and do not need overall examination to spell, and the guardrail upper surface spliced is smooth surface, splicing effect is good, is also convenient to produce in batches; In addition, the specification of the blank needed for this processing technology is more close to the specification of the cover plate 3 machined, and processing technology not only comparatively simple, workload significantly reduces, and can save a large amount of stone materials, reduces production cost.
Above are only the specific embodiment of the present invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
