Description
Technical field
The present invention relates to a kind of compact type chain vertical rings to stretch apparatus for shaping.
Background technique
Currently, environmental protection pressure increasingly sharpens with National Macroscopic economic adjustment, there is greatly private small moulded coal
Mine is closed or integrates, and mining area capacity also develops towards medium-and-large-sized group type direction.Often production of resources is rich for these large coal mines
Richness exploits year limit for length, this just needs it also to increase accordingly using the capacity of equipment of drag conveyor.Mining chain is defeated as scraper plate
The main parts size of machine is sent, structure, mechanical performance directly affect fully-mechanized mining working corollary equipment to the adaptability of working face.Root
According to coal mine user to the procurement demand of mining chain from the point of view of, the mining chain of domestic 38 or more Φ it is substantially all be compact type chain,
The chain advantage is that the increase of chain link sliding work area reduces unit pressure of the chain on groove body, improves vertical ring
Wear resistance, chain reduce height after more easily by sprocket wheel, and can reduce installed power and use small sprocket wheel
Drive assembly.Suitable for a lower height of operating condition of more demanding but intermediate channel to chain strength.
Competition with the continuous improvement that coal mine user requires chain performance and service life, between chain production unit
It is increasingly fierce, it forces it further to develop improvement to the production technology and processing technology of chain, is wanted with meeting different operating environment
It asks, improves the reliability and service life of chain, preferably serve mining cause.
Summary of the invention
The object of the present invention is to provide a kind of compact type chain vertical rings to stretch apparatus for shaping, can pass through in process of production
Stretching shaping is carried out to compact type chain vertical ring, the regular degree for founding ring circular arc position shape is squeezed with further improve, is made whole
The shape and geometric dimension of chain neutrality ring all reach stable homogeneous state.
A kind of compact type chain vertical ring stretching apparatus for shaping, its special feature is that: including workbench, on the workbench
Two hydraulic cylinders are installed, the piston rod of two hydraulic cylinders is passed through the upper stretching die on workbench vertically downward
Seat, and lower stretching die holder is fixedly installed on the piston rod, lower stretching die is installed on the lower stretching die holder, and preceding
Stretching die is installed on the upper stretching die holder stated, limited block is installed below the lower stretching die holder.
Wherein the piston rod of two hydraulic cylinders is parallel to each other, and upper stretching die is located among upper stretching die holder, drop-down
Mould is stretched to be located among lower stretching die holder.
The present invention provides a kind of compact type chain vertical ring stretch shaping machines, by process of production by compact
Chain vertical ring carries out stretching shaping, squeezes the regular degree for founding ring circular arc position shape with further improve, makes in whole chain
The shape and geometric dimension of vertical ring all reach stable homogeneous state.The vertical ring of stretched shaping can be linked preferably with flat ring,
Thoroughly avoid compact type chain in laying and use process, due to vertical ring circular shape is irregular inhomogenous with flat ring circular arc it
Between generate interference, " not Ka ", make chain more " softness ", stress condition more tends to equilibrium, improves the reliability of chain and makes
Use the service life.
Detailed description of the invention
Accompanying drawing 1 is the structural representation of the present invention；
Attached drawing 2 is the working principle of the invention figure.
Specific embodiment
As shown in Figure 1, 2, the present invention provides a kind of compact type chain vertical rings to stretch apparatus for shaping, including workbench,
Two hydraulic cylinders 1 are installed, the piston rod of two hydraulic cylinders 1 is passed through workbench vertically downward on the workbench
On upper stretching die holder, and lower stretching die holder is fixedly installed on the piston rod, under being equipped on the lower stretching die holder
Stretching die, and upper stretching die is installed on upper stretching die holder above-mentioned, limited block 3 is installed below the lower stretching die holder.
Wherein the piston rod of two hydraulic cylinders 1 is parallel to each other, and upper stretching die is located among upper stretching die holder, under lower stretching is located at
It stretches among die holder.
Embodiment 1:
As shown in Figure 1, the present invention is a kind of compact type chain vertical ring stretch shaping machine, including (left and right each one) is hydraulic
Oil cylinder 1 is equipped with (each one upper and lower) on 1 piston rod of hydraulic cylinder and stretches die holder 2, is equipped with drawing on stretching die holder 2
Mould 4 (each one upper and lower, to correspond with the upper and lower die holder 2 that stretches) is stretched, stretching below die holder 2 has a limited block 3.
As shown in Fig. 2, working as chain link in compact type chain vertical ring suspension clip pressure setting (referring to China Patent No.: ZL
201420062090.2) it after carrying out precompressed on, is linked between stretching die 4, under automatic operating state, hydraulic cylinder 1, which drives, to be drawn
Die holder 2 is stretched to move downward by arrow instruction direction in figure.Chain link is under the pulling force effect of stretching die 4, arc sections while elongation
Position is deformed (in chain link hatched example areas, that is, Fig. 2 at A).When stretch die holder 4 touch 3 position of limited block when, oil cylinder stop to
Lower movement, system pressure keeps 2s, to stablize chainring form and geometric dimension.After pressure maintaining, chain is taken out in 1 backhaul of hydraulic cylinder
Ring is completed to stretch shaping.
Application method of the invention is: bar being welded into monocycle, compact type chain vertical ring suspension clip is put into after heating
Pressure setting (patent No.: ZL 201420062090.2) carries out precompressed, is put into compact type chain vertical using heating residual temperature after taking-up
Stretching shaping is carried out on ring stretch shaping machine.Ring is stood using the compact that shaping of the present invention goes out, type structure feature is: vertical ring
Circular arc position regular shape, can preferably link with flat ring, thoroughly avoid compact type chain in laying and use process and flat
The interference that generates between ring circular arc, " not Ka ", make chain more " softness ", and stress condition more tends to equilibrium, and that improves chain can
By property and service life.
Upper table is using the compact type chain vertical ring related data suppressed after apparatus of the present invention, which executes
Standard be MT/T 929-2004.
Test proves that solving current domestic mine after using compact type chain vertical ring stretch shaping machine of the invention
The quality present in high-intensitive compact type chain vertical ring extrusion process and production defect.The present invention is to utilize compact type chain vertical
Ring stretch shaping machine founds ring to precompressed and carries out stretching shaping, improves the regular degree for squeezing vertical ring circular arc position shape, makes whole
The shape and geometric dimension of chain neutrality ring all reach stable homogeneous state, improve chain quality.
