Description
The present invention relates to a kind of seamless conic sleeve and manufacture method thereof of showing stand, belong to modular display frame attaching parts technical field.
The showing stand of prior art is readily removable combination multiple field mostly, these showing stands are all become with a plurality of layer architectures by four vertical supports, a plurality of equally spaced concave ring grooves and external taper chuck are set on every root post, corresponding with described concave ring groove, the inwall of external taper chuck is provided with the bulge loop that can embed concave ring groove, the outside suit one of external taper chuck has the sleeve of internal taper, and the layer frame of showing stand is welded on the described sleeve.By the design feature of showing stand as can be seen, the weight of layer frame self adds the weight of goods on the frame of upper strata, is mostly all born by the sleeve on four angles, therefore requires sleeve to have enough rigidity and tension, impact resistance.Sleeve of the prior art is made by metal plate or seamed steel pipe, these sleeves or have the crack or have weld seam, and its integral rigidity, threading property are poor, and tension, impact resistance are all very weak.For example: the disclosed a kind of name of Chinese patent communique is called " making method of taper sleeve of multi-layer platform display shelf ", the patent No. is the patent of invention of " 97106680.9 ", there is following shortcoming in this manufacture method: there is weld seam in the conic sleeve that (1) produces, weld seam is hard and crisp, threading property is poor, a little less than the resistance to tension, break easily when heavier or impulsive force is big at goods, showing stand itself, goods and personal safety are all constituted a threat to; (2) in manufacture process, need to freeze, and need butt welded seam to polish and polish, therefore make complex process, difficulty is big, equipment needed thereby is many, long in time limit, efficient is low, the cost height.
The objective of the invention is seamless conic sleeve and manufacture method thereof for a kind of showing stand is provided.
Purpose of the present invention can reach by taking following measure:
The seamless conic sleeve of showing stand has certain internal taper δ, and two ends form inside and outside lead angle γ, and its design feature is: the sidewall of sleeve does not have weld seam, inside and outside surface smoothing, and 0 °＜δ of internal taper≤15 ° is made of seamless steel pipe.
The seamless conic sleeve manufacture method of foregoing showing stand is characterized in cutting the seamless steel pipe of certain-length, and remove burr through two ends, fall lead angle, last punch forming, concrete manufacture process is as follows:
1) seamless steel pipe is cut into the length required, forms the cylinder type hollow tube with forming sleeve;
2) inside and outside both sides, the two ends of aforementioned cylinder type hollow tube are fallen lead angle, and the surperficial burr (burr) of in the process of falling the lead angle, pruning, the cylindrical sleeve that two ends have inside and outside lead angle γ formed;
3) the 2nd) cylindrical sleeve that forms strikes out the forming sleeve with internal taper δ the step, and 0 °＜δ≤15 °.
Purpose of the present invention also can reach by taking following measure:
1) with homemade cutter special seamless steel pipe is cut into the length suitable with forming sleeve, forms the cylinder type hollow tube, described cutter special is made of material bearing support and cutting head;
2) with homemade special-purpose cutter lead angle is fallen in inside and outside both sides, the two ends of aforementioned cylinder type hollow tube, and the two end surfaces burrs (burr) of in the process of falling the lead angle, pruning, the cylindrical sleeve that two ends have certain lead angle formed;
3) with homemade special-purpose stamping machine with the 2nd) cylindrical sleeve that forms of step strikes out the forming sleeve with internal taper δ, and 0 °＜δ≤15 °.
Compared with prior art, the present invention has following outstanding advantage:
1. product is a seamless conic sleeve.Because shaped article adopts seamless steel pipe to make, so conic sleeve do not have weld seam, and rigidity is strong, threading property is good, and resistance to tension is strong, can not break when heavier or impulsive force is big at goods, can guarantee showing stand itself, goods and personal safety.
2. manufacture process is simple.Since in manufacture process, omitted freeze, butt welded seam polishes and the complex process of polishing, so manufacturing process is simple, equipment needed thereby is few, the duration is short, efficient is high, cost is low.
3. equipment loss is little, allowance for depreciation is low.Cutting machine is homemade patent cutting machine, simple in structure, wearing terrain has only cutting wheel, and with the lathe tool appearance ratio on the engine lathe, described cutting wheel has the advantage of two aspects: first, long service life, the second, the cutting wheel number that needs to use simultaneously has only one, once needs to change many lathe tool unlike engine lathe, the 3rd, described cutting wheel price is low.Therefore, production cost of the present invention is low.
Describe the present invention below in conjunction with accompanying drawing:
Fig. 1 is the three-dimensional structure diagram of sleeve of the present invention.
Fig. 2 is a manufacturing flow chart of the present invention.
Fig. 3 is the user mode reference diagram of sleeve of the present invention.
As can be seen from Figure 1, this sleeve embodiment 1 is made of seamless steel pipe, and the inside and outside wall of sleeve does not have weld seam, and is smooth, smooth, its internal taper δ=5 °, and two ends form inside and outside lead angle γ.
As can be seen from Figure 2, the manufacture process of present embodiment is as follows:
1) open material, with homemade cutter special seamless steel pipe is cut into the required length of forming sleeve, form the cylinder type hollow tube, described cutter special is made of material bearing support and cutting head;
2) with homemade special-purpose cutter lead angle is fallen in inside and outside both sides, the two ends of aforementioned cylinder type hollow tube, and the two end surfaces burrs (burr) of in the process of falling the lead angle, pruning, the cylindrical sleeve that two ends have certain lead angle formed;
3) with homemade special-purpose stamping machine with the 2nd) cylindrical sleeve that forms of step strikes out the forming sleeve with internal taper δ, and 0 °＜δ≤15 °.
In the present embodiment, cutting machine is homemade patent cutting machine, is made of material bearing support and cutting head, and the cutting head is made of driving mechanism and cutter.
As can be seen from Figure 2, the present invention adopts seamless steel pipe to make, and whole manufacturing process has been omitted the complicated welding of technology, polished process, not only sleeve surface is smooth smooth, and intensity is big, stretching resistance is strong, and can significantly reduce process time, increase work efficiency, reduce production costs.
As can be seen from Figure 3, the overwhelming majority of layer frame self and top goods weight thereof is all born by the conic sleeve on four angles, therefore requires these conic sleeves must have enough intensity and tension, shear resistance.When there is weld seam in these conic sleeves, be not intermolecular combination owing to combine between scolder and on every side the material, so the shearing resistance of weld seam, that resistance to tension is not so good as steel pipe self is strong.Break easily when heavier or impulsive force is big at goods, can not guarantee showing stand itself, goods and personal safety.
