Said three-strand stretch-drawing machine includes the following several portions: front machine frame, rear machine frame, stretch-drawing buggy with chain, core rod, cylinder with charging stool, master block, storage frame, material-shifting device, material-pushing buggy, motor and blanking device. Said invention also provides the connection mode of all the above-mentioned portions, and also provides the working principle of said three-strand stretch-drawing machine and its concrete operation method.
Description
Technical field
The present invention relates to a kind of three-way stretcher, belong to the manufacturing technology field of copper and copper-alloy pipe-material stretcher.
Background technology
Existing copper pipe stretcher mainly is to adopt single line, two-wire, three-way stretching technique, and three-way stretcher is widely used because of its high stretching efficient in the copper pipe production of tubule footpath; The automatic charging mode of existing three-way stretcher is mainly: swinging and rocker-arm.Widely different rotatable major defect is: complex structure, owing to stopping power between support roller and widely different rotating cylinder is poor, cause copper pipe contraposition difficulty simultaneously, and the positioning accuracy between copper pipe and nib is poor, and stretching efficient is low; The major defect of rocker-arm is: feed mechanism need be made two covers, and needs the heavy caliber hydraulic cylinder that power is provided, and requires the aligning accuracy height, and floor space is big, has increased manufacturing cost and operating cost.
The automatic blanking mode of existing simultaneously three-way stretcher is mainly cylinder connect material formula blanking and the blanking of gravity landing formula.The connect material major defect of formula blanking of cylinder is: the discrepancy in elevation of nib and blanking frame is big; The major defect of gravity landing formula blanking is: the discrepancy in elevation of nib and blanking frame is big, and long copper pipe can't be realized automatic blanking.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in design, simple in structure, easy to operate practicality, the three-way stretcher of reliable operation.
The present invention is a kind of three-way stretcher, comprise forebay and afer bay, place the stretching dolly of band chain bar in the forebay, place the core bar on the afer bay, place the die holder between afer bay and the forebay, place the hopper of forebay top band storage rack and poking device, it is characterized in that also being provided with on the afer bay cylinder of band loading bracket, the bottom of forebay is provided with the electronic blanking device of belt of band finished product hopper.
Also can be provided with the pusher dolly on the described hopper.
The present invention compared with prior art has following outstanding advantage and good effect:
1, designed the lift feed mechanism that is made of cylinder and loading bracket voluntarily, complete machine is operated steadily reliably, contraposition is accurate, and the complete machine floor space is little, has saved the space, has improved the utilization rate of factory building.
2, adopt the electronic blanking device of belt to realize the copper pipe automatic blanking, shortened the stretching cycle, improved stretching efficient, also can prevent the copper pipe surface scratch, improved product quality and lumber recovery.
3, the stretching dolly directly is connected with chain, and speed multistage regulating system is achieved, and draw speed can be regulated according to technological requirement, has improved the quality of the surfaces externally and internally of copper pipe, has also improved stretching efficient.
The present invention is reasonable in design, and is simple in structure, easy to operate practicality, and reliable operation, and production efficiency is had increased significantly, and also improved product quality, shortened the production cycle, reduced production cost.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention;
Fig. 2 is an A-A face structural representation shown in Figure 1.
Among the figure, 1 is core bar, and 2 is afer bay, and 3 is loading bracket, and 4 is die holder, 5 is hopper, and 6 are the stretching dolly, and 7 is chain, and 8 is the pusher dolly, and 9 is forebay, 10 is cylinder, and 11 is storage rack, and 12 is poking device, and 13 is the electronic blanking device of belt, and 14 is the finished product hopper.
The specific embodiment
The present invention is mainly by forebay 9 and afer bay 2, place the stretching dolly 6 of band chain bar 7 in the forebay 9, place core bar 1 and the cylinder 10 of being with loading bracket 3 on the afer bay 2, place the die holder 4 between afer bay 2 and the forebay 9, place the hopper 5 of forebay 9 top band storage racks 11, poking device 12, pusher dolly 8, place electronic blanking device 13 formations such as grade of belt of forebay 9 bottom band finished product hoppers 14.
During work, copper pipe to be stretched is placed on the storage rack 11, shift onto in the hopper 5 by poking device 12, the loading bracket 3 that pushes cylinder 10 rises and puts in place, and to chain-dotted line position as shown in Figure 1, the workman is docked copper pipe with core bar 1, start pusher dolly 8 pushers, copper pipe is released hopper 5, and loading bracket 3 descends and puts in place, pusher dolly 8 backhauls simultaneously; The center contraposition of copper pipe and die holder 4 pushes nib, and dolly 6 backhauls that meanwhile stretch put in place, the action of stretching dolly 6 jaws, clamp copper mouth piece, stretching-machine master electric motor starting drives stretching dolly 6 by chain 7 and begins copper pipe is stretched, and makes the speed operation of stretching dolly 6 according to technological requirement control; When stretching fast finishing, the electronic blanking device 13 of belt starts, the belt operation, stretching finishes, by the time copper pipe is fallen on the belt, just is sent to 14 li of finished product hoppers, and the electronic blanking device 13 of belt stops, dolly 6 beginnings that stretch are simultaneously returned at a high speed, and carry out accurate speed governing and location according to technology and structural requirement.Repeat the above action copper pipe that stretches once more.
