Description

A kind of cold pilger mill
Technical field
The present invention relates to cold tube rolling equipment technical field, specifically a kind of cold pilger mill.
Background technology
Cold pilger mill is to utilize annular distance shape tubing to be carried out to the process equipment of cold conditions rolling.These facility have good cogging performance, non-ferrous metal seamless pipe that also can rolling general precision.The maximum feature of cold pilger mill is that stock utilization is high, and precision and surface roughness are all better than drawn tube.
With cold rolling process, can produce thin-walled, the high-quality tubing of wall and surfaces externally and internally no marking, effectively rolling high alloy, poor various steel pipes and the non-ferrous metal tube of plasticity as thin as a wafer.Through cold rolling tubing, organize crystal grain fine and closely woven, machinery and physical property are superior; Cold pilger mill is strong for the centering capacity of the thick deviation of original pipe, and physical dimension is accurate, smooth surface; Pass deformation can reach 60%-90%; Adopt that cold-rolling practice produces that tubing can reduce in a large number heat treatment, pickling, takes the lead, operation in the middle of aligning etc., reduced the trumpet of metal material, fuel, electric energy and other auxiliary material and manpower; Cold-rolling process can make stock utilization reach more than 95% (cold-drawn is 60%-80%), processing percentage elongation, and can to reach 2 ~ 10(cold-drawn processing percentage elongation be 1.1-1.5).
Domestic existing cold pilger mill adopts the material loading pattern of shutting down substantially, and cold pilger mill is produced after a pipe, next the root pipe of rolling of must shutting down, feed, start shooting.This cold pilger mill production efficiency is low, and the deficiencies such as specific yield energy consumption is large, poor product quality, lack the market competitiveness.
Summary of the invention
The present invention is directed to prior art deficiency, a kind of cold pilger mill is provided, this cold pilger mill can be realized automation mechanized operation, reduces cost of labor, reduces labour intensity.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of cold pilger mill, comprise pipe bin, described pipe bin is connected with automatic feeding, described automatic feeding is connected with sends lathe bed to, the described lathe bed of sending to comprises interior lubrication oil filler, core bar gripping mechanism, revolving feed device and core bar core bar device, on described core bar core bar device, be provided with pipe feeding trolley, the described lathe bed of sending to is connected with work housing, described work housing is connected with production tube blow tank, described production tube blow tank is connected with production tube bin, the described lathe bed and described automatic feeding and described work housing sent to is all connected with control device.This cold pilger mill is realized automatic charge by control device, and pipe is located automatically, automatic rolling, and self-emptying, and cycling, do not need workman to stop by hand machine reinforced, the labour intensity that improves rolling efficiency and reduce workman.
In technique scheme, preferred, on described pipe feeding trolley, be provided with approach switch, pipe end detector, described approach switch is connected described control device with described pipe end detector, and described control device connects variable-frequency motor.Approach switch can receive automatic feeding and pipe is sent to the signal of sending lathe bed to sends to control device, the length signals that pipe end detector can detect pipe sends to control device, and control device makes moving of car according to the length drives variable-frequency motor of pipe and enters into cut out roof door while sending in lathe bed completely at pipe.
The present invention compared with prior art, there is following beneficial effect: this cold pilger mill of the present invention is realized automatic charge by control device, pipe is located automatically, automatic rolling, self-emptying, and cycling, does not need workman to stop by hand machine reinforced, the labour intensity that improves rolling efficiency and reduce workman.
Accompanying drawing explanation
Fig. 1 is the structural representation of pipe bin and automatic feeding.
Fig. 2 is the structural representation of sending lathe bed to.
Fig. 3 is the structural representation of work housing and production tube blow tank.
Fig. 4 is the structural representation of feeding trolley.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail: referring to Fig. 1 to Fig. 4, a kind of cold pilger mill, comprise pipe bin 1, described pipe bin 1 is connected with automatic feeding 2, described automatic feeding 2 is connected with sends lathe bed 3 to, the described lathe bed 3 of sending to comprises interior lubrication oil filler 31, core bar gripping mechanism 32, revolving feed device 33 and core bar core bar device 34, on described core bar core bar device 34, be provided with pipe feeding trolley 35, the described lathe bed 3 of sending to is connected with work housing 4, described work housing 4 is connected with production tube blow tank 5, described production tube blow tank 5 is connected with production tube bin, the described lathe bed 3 and described automatic feeding 2 and described work housing 4 sent to is all connected with control device 6.This cold pilger mill is realized automatic charge by control device 6, and pipe is located automatically, automatic rolling, and self-emptying, and cycling, do not need workman to stop by hand machine reinforced, the labour intensity that improves rolling efficiency and reduce workman.
On described pipe feeding trolley 35, be provided with approach switch 351, pipe end detector 352, described approach switch 351 is connected described control device 6 with described pipe end detector 352, and described control device 6 connects variable-frequency motor 353.Approach switch 351 can receive automatic feeding 2 and pipe is sent to the signal of sending lathe bed 3 to sends to control device 6, the length signals that pipe end detector 352 can detect pipe sends to control device 6, and control device 6 makes moving of car according to the length drives variable-frequency motor 353 of pipe and enters into completely and send lathe bed 3 to and cut out roof door when interior at pipe.
