Description

A kind of contour roll forming mould dedicated lifting hook

Technical field

The utility model relates to hoisting and hanging field, especially a kind of contour roll forming mould dedicated lifting hook.

Background technique

Common suspender belt is used in existing contour roll forming mold demolition, installation, and contour roll forming die shape belongs to irregularly, sling with suspender belt, and 1. is more difficult Find equalization point；2. even if contour roll forming mold inner hole also can be banking find relative equilibrium position；3. contour roll forming mold inner hole with Board axis front end shaft diameter is not much different, and differs only by nearly 30MM；So dismounting contour roll forming mold or alignment board turn with common suspender belt It is relatively time consuming, laborious when axis, low efficiency, waste of time.

Summary of the invention

In view of the deficienciess of the prior art, the utility model aim is to provide a kind of assembly and disassembly difficulty for reducing contour roll forming mold And improve a kind of contour roll forming mould dedicated lifting hook of the installation effectiveness of contour roll forming mold.To achieve the above object, the utility model use with Lower technical solution:

The utility model discloses a kind of contour roll forming mould dedicated lifting hooks, for lifting contour roll forming mould to board main shaft, board Front-end of spindle is provided with step section comprising hollow cylindrical hook body and suspension hook handle.The suspension hook handle and suspension hook sheet The side of body is fixedly connected.Inner hole is provided in the hook body.The inner hole is used for and step section location fit.It is described to hang Wall thickness between the upper end of the inner hole of hook ontology and the upper end of cylindrical outer wall is equal to the difference in height of board main shaft and step section.Institute The inner hole stated is mutually eccentric with hook body cylindrical outer wall.The diameter of the hook body cylindrical outer wall is straight with board main shaft Diameter is identical.

Further, the hook body diameter of bore is 1.5-2.5mm bigger than the diameter of main shaft step section.

Further, the suspension hook handle includes for the interconnecting piece affixed with hook body side and from the company The fixed part being bent to form at the top of socket part to hook body side.The end of the fixed part offers one for connecting lifting The through-hole of equipment.

Further, the distance between the through hole center axis and interconnecting piece are greater than the half of hook body length.

After above-mentioned technical proposal, the utility model has the beneficial effects that

It substantially reduces the assembly and disassembly difficulty of contour roll forming mold and improves the installation effectiveness of contour roll forming mold.The innovation is in tubeless product The breakthrough progress played on wheel rim contour roll forming mold assembling and dissembling speed.Enterprise is set to obtain bigger productivity effect.Structure is simple, can be It is promoted and applied in steel ring without inner tube production.

Specific embodiment

In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing and have Body embodiment is described in further detail the utility model.

As shown in Figure 1, Figure 2, Figure 3 shows, the utility model discloses a kind of contour roll forming mould dedicated lifting hooks, for hanging contour roll forming mould 5 It is filled on board main shaft 3,3 front end of board main shaft is provided with step section 4.It includes hollow cylindrical hook body 1 and suspension hook handle Hand 2；The suspension hook handle 2 is fixedly connected with the side of hook body 1.Suspension hook handle 2 includes for solid with hook body side The interconnecting piece 22 connect and the fixed part 21 being bent to form from the top of the interconnecting piece to hook body side, the end of fixed part 21 End offers one for connecting the through-hole 23 of lifting equipment.The distance between 23 central axis of through-hole and interconnecting piece 22 L1, which are greater than, to be hung The half of hook body length L2.

Inner hole 12 is provided in hook body 1.Inner hole 12 is used for and 4 location fit of board step section.Hook body 1 it is interior Wall thickness TI between the upper end in hole 12 and the upper end of cylindrical outer wall 11 is equal to the difference in height T2 of main shaft step section 4.Hook body The diameter D1 of outer wall 11 and the diameter D3 of board main shaft 3 are identical.Hook body diameter of bore D2 is bigger than the diameter D4 of step section 4 2mm。

As shown in Figure 3, Figure 4,1 inner hole 12 of hook body and 11 phase of hook body cylindrical outer wall are eccentric, and O1 is suspension hook sheet The center of circle of external wall, O2 are the center of circle of hook body inner hole.Two circle center distance a are 1mm.Guarantee both to be able to satisfy by bias Hook body wall thickness T1 is equal to the difference in height of board main shaft step section T2, and is able to satisfy 12 diameter of hook body inner hole and compares step section The big 2MM of diameter, such suspension hook can very easily will contour roll forming mould 5 put into main shaft in.

The course of work of the utility model as shown in Figure 3: suspension hook alignment is put into contour roll forming mould 5 and shifts bottom onto, makes contour roll forming mould 5 are close to the interconnecting piece 22 of suspension hook handle.Contour roll forming mould 5 can be sling using crane, it, will be in suspension hook before close board main shaft 3 Hole 12 is directed at step section 4 and gently one pushes away and can be inserted in step section 4.Again suspension hook down gently one put make hook body inner hole 12 with Step section 4 contacts, and can easily put on board axis 3 contour roll forming mould 5, complete die-filling.

It is greatly improved the efficiency of replacement contour roll forming mold using this suspension hook dress contour roll forming mold, plays one to improve production efficiency Fixed effect.It is 2H or so the time required to replacing contour roll forming mold every time before innovation implementation, after special hanger, replaces contour roll forming It is 1.5H or so the time required to mold.Personnel needed for one rim line continuous productive process press 17 people of standard configuration, and the time is saved in primary mold changing For 17*0.5H=8.5H, calculated by 15 yuan/hour, 8.5*15=127.5 yuan.Mold changing can save 127.5 yuan every time.One factory There are 6 lines, is calculated by the frequency for changing a mould daily, 127.5*30*12=45900 yuan/year.

To sum up, the utility model structure is simple, is easy to use, and improves production efficiency, increases the performance of enterprises, is suitable for without in It is promoted and applied in tyre steel ring production.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.
