Description
Technical field
The utility model relates to a kind of steel pintle chain bar, relates in particular to a kind of steel pintle chain bar of low initial wear elongation percentage.
Background technique
The steel pintle chain is a kind of distributor that is widely used in granular materials such as salt, fertilizer.In pastoral farming as feed selector and hay processing equipment.In Wood Processing as low speed conveying equipment and other similar conveying system.Traditional steel pintle chain is made up of chain link and bearing pin as shown in Figure 1, and a plurality of chain links and a plurality of bearing pin be by being coupled to each other the formation chain, and carries out cold riveting by the two ends to bearing pin, is bound up.Chain link is the carrier bar of a U-shaped bending structure, and the back of its bending part forms circular arc and sprocket engagement, and bearing pin is a cylindrical structural.During the chain tension operation, there is the gap of 0.8～1.2mm in the closed end of bearing pin and curved chain link inboard as shown in Figure 2.When this structure caused chain to move in the early stage, the length direction of surface of contact only was the thickness of two blocks of carrier bars between bearing pin and the curved chain link closed end inboard, and hinged area is little, so the initial wear elongation of chain is big.Have only after eliminate by wearing and tearing in the gap of the closed end inboard of bearing pin and curved chain link, the length of chain just tends towards stability.
Because the closed end of curved chain link relies on a bending and forming, the formed bull nose of bending part has reduced and the effective length of action size of sprocket wheel.Effective engagement size of curved chain link and sprocket wheel is lower than 60% of closed end acromere size as shown in Figure 3, and is like this then excessive wear easily takes place joggle(d) joint synapsis chain and sprocket wheel.
Therefore, there is defective in prior art, needs to improve.
The model utility content
At the steel pintle chain bar of low initial wear elongation percentage, the utility model need solve two problems: 1, reduce the gap between curved chain link closed end inboard and bearing pin, improve the effective area of contact between bearing pin and carrier bar; 2, strengthen the length at curved chain link and sprocket engagement place.Above-mentioned deficiency of the prior art provides a kind of steel pintle chain bar of low initial wear elongation percentage.
The technical solution of the utility model is as follows:
A kind of steel pintle chain bar of low initial wear elongation percentage, by at least one chain link, described at least one chain link comprises chain link opening end and chain link closed end, described chain link opening end connects to form by at least one bearing pin and described chain link closed end, wherein, the described chain link closed end of described at least one chain link is a groove.
Described steel pintle chain bar, wherein, the inner groovy of described bearing pin and described chain link closed end bottom tightens to connect airtight at same horizontal plane touches.
Described steel pintle chain bar, wherein, described inner groovy bottom is two 90 degree right angles.
Described steel pintle chain bar, wherein, described inner groovy bottom is two arc round angles, described arc round angle is R0.5mm.
Described steel pintle chain bar, wherein, described inner groovy bottom is two arc round angles, described arc round angle is R0.3mm.
Described steel pintle chain bar, wherein, the outer bottom portion of groove of described chain link closed end is two 90 degree right angles.
Described steel pintle chain bar, wherein, the outer bottom portion of groove of described chain link closed end is two arc round angles, described arc round angle is R0.5mm.
Described steel pintle chain bar, wherein, the outer bottom portion of groove horizontal direction force area of described chain link closed end be not less than described chain link closed end outer bottom portion of groove total length 80%.
Described steel pintle chain bar, wherein, the outer bottom portion of groove horizontal direction force area of described chain link closed end be not less than described chain link closed end outer bottom portion of groove total length 90%.
By adopting the steel pintle chain bar of low initial wear elongation percentage of the present utility model, the inner side surface of its endoporus side surface and curved chain link is in same straight line, area of contact has improved more than 4 times between curved chain link inner surface and the bearing pin, so then under equal carrying condition, the unit area bearing capacity has reduced by 4 times, it has slowed down the relative wear amount between bearing pin and the curved chain link, reach the effect of the initial wear elongation percentage decline of chain, and improved the deformation extent of bending part, the more not shaping mode of tensile strength of chain link has improved more than 15%.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model is achieved in that
Embodiment one
By on the bending and forming operation, increase the synchronous limit stoper of a cover newly at curved chain link carrier bar, in the time of the bending bending curved chain link closed end is carried out shaping, increase position effective length (being increased to greater than 80%B less than 60%B) by former with sprocket engagement, R0.5mm is reduced to by R1.5mm in the circular arc R angle at the inboard two ends of closed end simultaneously, supports for follow-up punching provides a complete similar die.
The chain link carrier bar is bent in the closed end shaping, because inboard bending R angle comprises the reduction of outside bending angular radius, provides molding condition for the bending inner side surface of the endoporus punching out process of follow-up closed end and curved chain link carrier bar is in a straight line.
The curved chain link of closed end after shaping, the inner side surface of endoporus side surface and curved chain link is in same straight line, area of contact has improved more than 4 times between curved chain link inner surface and the bearing pin, so then under equal carrying condition, the unit area bearing capacity has reduced by 4 times, slow down the relative wear amount between bearing pin and the curved chain link, reached the effect of the initial wear elongation percentage decline of chain.To the improved deformation extent of bending part of the shaping of closed end, the more not shaping mode of tensile strength of chain link has improved more than 15%.
