Compared with the prior art, the utility model discloses having carried out thorough change to original working of plastics structure, not had at the working of plastics under the condition of strengthening rib, the installation of application metal lining reaches the purpose that improves working of plastics base member intensity.
Description
Technical field
This utility model relates to working of plastics increases strength fields, is specifically related to a kind of working of plastics metal lining and fastens
Part.
Background technology
Existing working of plastics easily occurs deformation, problems of crack in tightening process for a bolt, can only be by fastening part
Position increases reinforcement intensity and improves plastic eyelet intensity, but this can be greatly increased mould development expense, and cannot be complete
Complete solution is determined the deformation in working of plastics fastener cycle and problem of Cracking.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of structure letter is provided
Singly, the working of plastics metal lining securing member of working of plastics intensity, low cost can be greatly increased.
The purpose of this utility model can be achieved through the following technical solutions: a kind of working of plastics metal lining fastens
Part, reinforces working of plastics in tightening process for a bolt for working of plastics, and described working of plastics arranges circular port
Hole, this securing member is hollow cylinder, arranges axial straight trough in the side of securing member, and this straight trough is by securing member
Inwall is through with outer wall, and described securing member assembles by the way of interference fit with working of plastics.This practicality is new
Type eliminates existing working of plastics and uses increase reinforcement to the method improving intensity, carries out original plastic piece structure
Thorough change, in the case of working of plastics is without reinforcement, uses the installation of metal lining to reach to improve working of plastics base
The purpose of body intensity.
The thickness of described securing member is 1.5mm, and the width of described straight trough is 1～1.6mm, increases the purpose of straight trough
It is to make securing member to shrink, when mounted in convenient loading working of plastics, after loading working of plastics, securing member
Spreading, is tightly stuck in the circular hole of working of plastics.
The material of described securing member includes 65Mn, and this securing member passes through mould punching, deburring, surface-coated
Processing, this Tensile strength is high and domestic being prone to is bought to use 65Mn steel to be because, and can promote the present invention
The intensity of securing member, and cost can be reduced.
Described working of plastics is provided with the circular opening running through plastic plate, when unassembled, and the diameter of described circular opening
Less 0.2mm than securing member external diameter.
The thickness of described working of plastics is identical with the height of described securing member.
The both ends of the surface of described securing member are provided with chamfering, angle >=15 ° of chamfering, arrange the purpose of chamfering for making
Securing member inserts working of plastics and is more prone to.
When working of plastics is reinforced by described securing member, securing member is inserted in the circular opening of working of plastics, pass through
The mode of interference fit is assembled, and ensures that metal lining the phenomenon that gets loose will not occur in transportation with this, dress
The working of plastics crush resistance strength having metal lining is greatly improved.
The external diameter of described bolt is identical with the internal diameter of the securing member after interference fit assembling.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) the art of this patent be skillfully constructed, novel in design, and the reinforcing rib structure phase that existing working of plastics is loaded down with trivial details
Ratio, can complete in metal only need to push the mating hole of working of plastics to install.
(2) the art of this patent is also good project for the investor, puts into the highest, the big market of small item, investment
Return rate is at a relatively high.
(3) increase work efficiency and reduce cost: original working of plastics was because adding to obtain reinforcing rib structure, and die cost is non-
Normal high and the process-cycle is the longest, and existing mode greatly reduces die sinking cost and the cycle of plastic parts, only needs
Metal lining pushes plastic eyelet can complete to install, and improve the intensity of plastic substrate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the assembling schematic diagram of securing member and working of plastics；
Fig. 3 is working of plastics bolt structural representation when fixing.
Wherein, 1 is working of plastics, and 2 is securing member, and 3 is bolt, and 4 is nut.
Detailed description of the invention
Elaborating embodiment of the present utility model below, the present embodiment with technical solutions of the utility model is being
Implement under premise, give detailed embodiment and concrete operating process, but protection of the present utility model
Scope is not limited to following embodiment.
Embodiment 1
A kind of working of plastics metal lining securing member, its structure as it is shown in figure 1, this securing member is hollow cylinder,
Arranging axial straight trough in the side of securing member, this straight trough is through with outer wall by the inwall of securing member, this securing member
Thickness is 1.5mm, and the width of straight trough is 1.0mm, and this securing member is passed through mould punching, unhairing by 65Mn shaped steel
Thorn, surface-coated process, and arrange 60 ° of chamferings at securing member two ends.
When this securing member 2 is for reinforced plastics part 1 intensity, on working of plastics, the diameter of circular opening is than securing member
The little 0.2mm of external diameter, extrudes securing member 2, and straight trough width reduces, i.e. the external diameter of securing member 2 reduces,
When the external diameter of securing member 2 is decreased to, with when the diameter of hole is identical on working of plastics 1, securing member 2 be inserted working of plastics
In the hole of 1, and flush with working of plastics 1 both ends of the surface, now, securing member 2 by the way of interference fit with mould
Materials and parts 1 complete assembling, and its assembling schematic diagram is as shown in Figure 2.
When working of plastics 2 needs bolt to fix, bolt 3 is inserted in working of plastics 1 hole assembling securing member 2,
Now the external diameter of bolt 3 is identical with the internal diameter of securing member 2, and bolt 3 will not rock, finally by nut 4 by spiral shell
Bolt 3 is fixed, thus reaches the purpose of fixed plastics part, and now the structure of working of plastics is as shown in Figure 3.
The technology of the present invention eliminates existing working of plastics and uses increase reinforcement to the method improving intensity, moulds original
Materials and parts structure has carried out thorough change, in the case of working of plastics is without reinforcement, uses the installation of metal lining to reach
Improve the purpose of working of plastics matrix strength.
Embodiment 2
Using the securing member of structure similar to Example 1, both differences are that the securing member two ends of the present embodiment set
Putting 15 ° of chamferings, paper well width is 1.6mm, in the case of working of plastics is without reinforcement, uses the present embodiment gold
The installation belonging to lining reaches to improve the purpose of working of plastics matrix strength.
Embodiment 3
Using the securing member of structure similar to Example 1, both differences are that the securing member two ends of the present embodiment set
Putting 45 ° of chamferings, paper well width is 1.3mm, in the case of working of plastics is without reinforcement, uses the present embodiment gold
The installation belonging to lining reaches to improve the purpose of working of plastics matrix strength.
