Abstract

The invention belongs to the field of calendering equipment, and particularly relates to a rotary bending stretcher rotary mechanism. The mechanism comprises a base, a chain wheel which is rotationally arranged on the base and coaxially and fixedly connected with an extrusion die of the stretcher, a chain movably connected with the base and an element supplying power to drive the chain, wherein the chain is meshed with the chain wheel. Compared with prior art, the mechanism has the advantages of low manufacturing and mounting precision, big bearing capability and long service life; moreover, the whole structure of the mechanism is more compact in size, and the mechanism can work in severe environments.

Description

Revolving gear of rotating-bending drawframe
Technical field
The present invention relates to a kind of rotating mechanism that is used for the rotating bending drawframe of metal processing.
Background technology
Revolving gear of rotating-bending drawframe generally adopts band transmission or gear drive in the prior art, thereby drives the extrusion die circumgyration stretch of stretching-machine, and band transmission and the common shortcoming of gear drive are that load is little.When processing elevator armrest support, need use stretching-machine steel plate bending is become " J " font, and require the transmission system of stretching-machine that bigger load can be provided.The shortcoming of the gear-driven stretching-machine of above-mentioned employing is: there is size restrictions in gear in processing; And the size of elevator armrest support and extrusion die is very big; Be difficult to find gear wheel to match with it, gear drive only is applicable to closely the motion with little load in addition, and is bigger in the loss of the situation lower gear of big load; Life-span is short, and the manufacturing cost of gear is higher.Adopt the shortcoming of the stretching-machine of band transmission to be: band be prone to triboelectrification, and its power that acts on the axle is bigger in the long-term course of work, the life-span is short.
Summary of the invention
The objective of the invention is to solve technical problems such as the cost that exists in the prior art is high, load is little, service life is short, a kind of rotating mechanism of simple in structure, the rotating bending drawframe that is easy to realize is provided.
The technical scheme that the present invention adopted is: a kind of revolving gear of rotating-bending drawframe; It comprises base, be arranged on the described base rotationally and with the coaxial sprocket wheel that is fixedly connected of the extrusion die of stretching-machine, be connected the chain on the described base and offer the element of described chain with driving force movably, described chain is meshed with described sprocket wheel.
Described chain comprises a pair of clamping plate that are parallel to each other, a plurality of roller that is arranged on rotationally between the described a pair of clamping plate, has the gap of the teeth insertion that can supply described sprocket wheel between described a plurality of rollers.
Described revolving gear of rotating-bending drawframe has a pair of described sprocket wheel and a pair of described chain, the coaxial fixed connection of described pair of sprocket, and described pair of sprocket is meshed with described a pair of chain respectively.
Be set with propulsion cylinder on the described base, described clamping plate are fixedly connected on the piston rod of described propulsion cylinder.
Described roller comprise both ends be located in Roller Shaft on a pair of clamping plate of described chain respectively, between described a pair of clamping plate and be set in the lining in the described Roller Shaft outside.
The present invention is through chain and sprocket engagement transmission; The extrusion die that drives stretching-machine rotates, and compares with traditional gear drive, and manufacturing of the present invention and installation accuracy are lower; When chain and chain gear transmission; The suffered power of the tooth of sprocket wheel is less, and corresponding bearing capacity is bigger, and certain buffering and damping performance are arranged; Chain is less to the pulling force of axle, and under the same service condition, the life-span is longer, and in addition, the overall structure size is also more compact; The wearing and tearing ratio of elongation of chain is slower, and it is less that workload is regulated in tensioning, and can under adverse circumstances, work.

The specific embodiment
Shown in accompanying drawing 1 to accompanying drawing 4; A kind of revolving gear of rotating-bending drawframe; It comprises base 1, is arranged on and is fixedly connected with the mould placenta 16 that is used for fixing extrusion die on main shaft 15 on the base 1, the main shaft 15, is arranged on the described base 1 rotationally and coaxially is fixedly connected on sprocket wheel 27 on the main shaft 15, is connected the chain 21 on the described base 1 and be fixedly installed on the propulsion cylinder 104 on the base 1 movably rotationally, and described chain 21 is meshed with described sprocket wheel 27.
Described chain 21 comprises a pair of clamping plate that are parallel to each other 44, a plurality of roller 46 that is arranged on rotationally between the described a pair of clamping plate 44, has the gap that the teeth that can supply described sprocket wheel 27 are inserted between described a plurality of rollers 46.Described clamping plate 44 are fixedly connected on the piston rod 1041 of described propulsion cylinder 104, drive this propulsion cylinder 104, make piston rod 1041 drive chain 21 and move, and rotate thereby drive sprocket wheel 27.Propulsion cylinder 104 is fixedly installed on the base 1 through oil cylinder hanging feet 106.
For improving the stability of stretching-machine; Increase its maximum load; Described revolving gear of rotating-bending drawframe has a pair of described sprocket wheel 27 and a pair of described chain 21; Described pair of sprocket 27 coaxial fixed connections, described pair of sprocket 27 are meshed with described a pair of chain 21 respectively.
Described roller 49 comprise both ends be located in Roller Shaft 50 on a pair of clamping plate 44 of described chain 21 respectively, between described a pair of clamping plate 44 and be set in the lining 46 in described Roller Shaft 50 outsides.
