Abstract
A chain type draw-off gear comprises an upper chain wheel transmission device and a lower chain wheel transmission device, wherein a drawing mechanism is arranged at the joint part of the upper and the lower chain wheel transmission devices, the drawing mechanism comprises an upper pressing block, an upper transmission chain, a lower transmission chain and a lower pressing plate, wherein a pair of drawing gelatin blocks is arranged between the upper transmission chain and the lower transmission chain, and draw holes matched with the diameter of a pulled pipe are formed on the drawing gelatin blocks. Both the upper transmission chain and the lower transmission chain comprise pin shafts, inner chain plate sleeves, outer chain plates and needle bearings; and the drawing gelatin blocks are mounted on the outer chain plates. Due to the adoption of the drawing mechanism in the upper and the lower chain wheel transmission mechanisms, and the arrangement of the needle bearings in the upper and the lower chain wheels, rolling friction between a chain and a hold-down strip is formed through the needle bearings arranged in the upper and the lower chain wheels, a friction force is greatly reduced, high-speed drawing is achieved, the gelatin blocks are adopted for clamping a copper pipe, so that not only is the clamping force enhanced, but also the deformation of the pipe is prevented. Moreover, a compressing and adjusting device is arranged, so that micro adjustment to the pressing force can be applied, and the most appropriate pressing force is achieved.
Description
Technical field
The utility model relates to a kind of chain type draw-off gear of tubing, specifically is the drawing equipment that a kind of inner screw thread copper pipe that is suitable for big caliber is produced.
Background technology
Inner screw thread copper pipe is widely used in refrigeration industry.The production equipment of internal thread is by realizing that principle mainly is divided into moulding section and traction element; What moulding section adopted is that high-speed electric expreess locomotive drives spinning apparatus around the inner forming principle that is placed with the light pipe outer surface high speed spinning of screw thread core print; But realize the continuous production of inner screw thread copper pipe, must have tractive unit to assign to provide power.Mode of traction has chain type drawing and the drawing of V-type dish at present.According to the design feature of drawing equipment, V-type dish draw-off gear mainly is applicable to small caliber inner screw thread copper pipe, is the production of the inner screw thread copper pipe of 5mm like external diameter, and such inner screw thread copper pipe is mainly used in the domestic air conditioning industry.External diameter is that the above bassoon caliber inner screw thread copper pipe of 9.52mm is mainly used in the condenser of producing central air-conditioning, and the external diameter specification mainly contains 12mm, 12.7mm; 15mm, 15.87mm etc. are because the required pulling capacity of copper pipe moulding of these specifications is bigger; V-type dish draw-off gear can not satisfy, and generally adopts chain type drawing structure in the industry, but chain type drawing in the past exists drawing speed low; A difficult problem easy to wear has restricted the raising of internal thread production efficiency.
The utility model content
The purpose of the utility model is to above-mentioned existing problems and deficiency a kind of chain type draw-off gear that can realize smoothly than the drawing of bassoon caliber inner screw thread copper pipe to be provided.
The technical scheme of the utility model is achieved in that
A kind of chain type draw-off gear comprises the upper sprocket wheel transmission device, the lower sprocket transmission device; Be provided with tightening plate on the upper sprocket wheel transmission device, on the lower sprocket transmission device, be provided with tensioner wheel plate down, be provided with drawing mechanism in the joint portion of upper and lower sprocket transmission device; Said drawing mechanism comprises upper holder block; Upper and lower driving-chain, lower platen, wherein: be provided with the drawing blob of viscose between the driving-chain up and down; On the drawing blob of viscose, be provided with and, be provided with glue in the outside of each drawing blob of viscose and buckle by the suitable pulling eye in trombone slide footpath.Above-mentioned driving-chain up and down comprises bearing pin respectively, the inner plate cover, and outer plate and needle bearing, above-mentioned each drawing blob of viscose is installed on the outer plate.
The utility model makes between chain and the press strip through the needle bearing that in last lower sprocket, is provided with to form rolling friction owing to adopted the drawing mechanism that in chain wheel driving mechanism up and down, is provided with, and has significantly reduced friction; Realize high speed drawing, and adopted blob of viscose clamping copper pipe, both can increase the clamping dynamics; Prevented the distortion of pipe again, in addition, set clamping adjustment device; Can implement micro-adjusting to thrust, realize the most appropriate thrust.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the general structure sketch map of the utility model chain type draw-off gear;
Fig. 2 is the N-N cutaway view of Fig. 1.
The specific embodiment
Show that like Fig. 1, Fig. 2 a kind of chain type draw-off gear comprises upper sprocket wheel transmission device 1; Lower sprocket transmission device 5 is being provided with tightening plate 11 on the upper sprocket wheel transmission device 1, on lower sprocket transmission device 5, be provided with expansion tightening wheel 51 down; Be provided with drawing mechanism in the joint portion of sprocket transmission device 1,5 up and down, said drawing mechanism comprises upper holder block 33; Driving-chain 4 up and down, lower platen 52, wherein: be provided with drawing blob of viscose 45 between the driving-chain 4 up and down; On drawing blob of viscose 45, be provided with and, be provided with glue in the outside of each drawing blob of viscose and buckle 47 by the suitable pulling eye 46 in trombone slide footpath.Above-mentioned driving-chain 4 up and down comprises bearing pin 41 respectively, inner plate cover 42, and outer plate 43 and needle bearing 44, above-mentioned each drawing blob of viscose 45 is installed on the outer plate 43.
Above above-mentioned upper holder block 33, be provided with some covers and compress adjusting device 3; The said adjusting device 3 that compresses comprises; By the lift 31 that Worm and worm-wheel gearing is formed, connecting axle 32 and press strip 34 are provided with the regulating block 34 that stretches out and be pressed on lower platen 33 in the lower end of lift 31.The above-mentioned adjusting device 3 that compresses is 3 covers.
As shown in Figure 2, above-mentioned drawing mechanism is by bearing pin 41, inner plate cover 42, and outer plate 43, needle bearing 44, drawing blob of viscose 45 is formed.Inner plate cover 42 adopts standard 24A roller chain; Bearing pin 41 passes inner plate cover 42; The outer plate 43 and needle bearing 44 of 24A roller chain installed at two ends respectively; Bearing pin 41, outer plate 43 and needle bearing 44 form a whole, can and inner plate relatively rotate between overlapping 42, thereby realized the transmission requirement of chain and sprocket wheel.When the blob of viscose clamping copper pipe on the last lower chain is realized drawing, must compress lower chain.Press strip 34 is pushed down the needle bearing 44 at bearing pin 41 two ends respectively through compressing adjusting device 3, and chain forms rolling friction between chain and the press strip 34 in the running, has reduced frictional force greatly, has realized high speed drawing.
The described worm and gear lift that compresses adjusting device 3 has connecting axle to connect motion simultaneously, can realize moving up and down of upper holder block 33 and trace adjusting through the axle that is rotationally connected.When last lower chain thrust was not enough, the frictional force that produces between drawing blob of viscose 45 and the copper pipe was less than the required pulling capacity of copper pipe moulding, and copper pipe will skid, and when thrust exceeds standard, will flatten copper pipe.So the depressing adjusting and can realize the most appropriate thrust of trace.
