Description

TECHNICAL FIELD

[0001] The utility model relates to copper strip production equipment technical field, especially a kind of flattening device for production and processing of conductive copper bar. BACKGROUND

[0002] Wire copper bar (also known as copper busbar or copper busbar) is a long conductor made of high-purity copper material, which is mainly used for transmitting current and connecting electrical equipment, and has excellent electrical conductivity and heat conduction performance, ensuring stable transmission of current and being less prone to failure. Copper bar has a wide range of applications in the field of electrical equipment, especially in complete power distribution devices, for example, U, V, W phase busbars and PE busbars in power distribution cabinets are usually made of copper bar; in addition, copper bar is also used in electrical engineering such as high-low voltage electrical appliances, switch contacts, power distribution equipment, bus ducts, as well as large-current electrolytic smelting engineering such as metal smelting, electrochemical plating and chemical caustic soda.

[0003] In the prior art, wire copper bar is generally prepared by hot rolling or cold rolling. In actual situations, copper bar is affected by its own quality problems, as well as storage, transportation, hoisting and other factors, and there is a risk of bending or forming depressions and protrusions on the surface of the copper bar, which can adversely affect the end application (for example, due to bending, it cannot be easily installed in the relevant position of the electrical power distribution cabinet, connected between two electrical equipment or power supply terminals; for example, surface depressions or protrusions can reduce the effective conductive area of the copper bar, increase the resistance and affect the transmission efficiency of the current, etc.). In the prior art, for a section of bent or surface-depressed or protruding copper bar, especially in production areas with small scale and low capital investment (such as small power distribution cabinet manufacturers), the copper bar is placed in the processing position by the staff, and the copper bar is processed flat by the staff using hammering method or the like. The above-mentioned all-manual processing will bring inconvenience to the staff, increase labor intensity and production cost, and also adversely affect the quality of the copper bar (hammering method can easily form non-consecutive or consecutive concave surfaces on the surface of the copper bar). SUMMARY

[0018] Figure 1 、 2 , 3, electromagnetic valves DC1 and DC2 are normally closed valve core electromagnetic valves. The driving gear 6 is engaged with the lower driven gear 1 of the left end fixed seat, and the two driven gears 1 are engaged. The distance between the two sets of rollers 3 is consistent with the thickness of the copper bar. The front end bottom plate 4 of the two sets of rollers 3 is provided with a support table 11 (convenient for workers to put the copper bar into the two rollers 3 through the support table 11). The internal contact of the temperature control switch W is normally closed. The number of teeth of the two driven gears 1 is consistent, and the number of teeth of the driving gear 6 is less than that of the driven gear 1. In the temperature control circuit, the force receiving surface of the temperature control switch W is in close contact with the outside of the oil tank 91, one end of the temperature control switch W is connected with the positive power input end of the relay J1. The power input ends 1 and 2 feet of the power module U1, the power input ends of the two power switches S1 and S2, the control power input end of the temperature control circuit and the two poles of the alternating current 220V power supply are respectively connected through wires. The power output ends of the two power switches S1 and S2 and the power input ends of the oil pump M1 and the motor speed reduction mechanism M2 are respectively connected through wires, the power output ends 3 and 4 feet of the power module U1 and the third power switch S3 and the fourth power switch S4, the other end of the temperature control switch W of the temperature control circuit are connected through wires, the control power output end of the temperature control circuit The two normally open contact ends of the relay J1 and the power input ends of the electric heating tube RT are respectively connected through wires, the power output ends of the third power switch S3 and the fourth power switch S4 and the negative power output end 4 feet of the power module U1 and the power input ends of the two electromagnetic valves DC1 and DC2 are respectively connected through wires.

[0019] Figure 1 、 2The new type has compact overall structure, convenient use, and relatively low cost compared with large-scale leveling equipment. After 220V AC power enters the power input end of the power module U1, the stable DC 12V power output of the power module U1 enters the power input end of the power switch S3, S4 and the temperature control circuit. After the power switches S1, S2, S3 and S4 are turned on, the motor speed reduction mechanism M1 is powered on, and the power output shaft drives the driving gear 6 to rotate clockwise, the driving gear 6 drives the lower driven gear 1 of the fixed seat 2 and the roller 3 to rotate counterclockwise (the outer ring of the bearing 8 rotates, the inner ring of the bearing 8 does not rotate, and the corresponding connecting pipe, liquid outlet pipe and liquid inlet pipe do not rotate, which ensures that the heated oil flows in and out), the lower driven gear of the fixed seat 2 drives the upper driven gear 1 of the fixed seat 2 and the roller 3 to rotate clockwise. In this way, the worker places the copper bar to be processed between the two rollers 3, and the heated roller 3 can effectively flatten the bent part and the concave or convex part of the heated copper bar (the movement towards the rear end of the copper bar entering the two sets of rollers 3 is flattened by the two sets of rollers 3). In this application, after the oil pump M1 is powered on (the valve core of the electromagnetic valve DC1 and DC2 is opened), the heat-conducting oil (about 200°C) in the heating tank 91 is pumped out and then pumped into the two sets of rollers 3, the two sets of rollers 3 are heated, and the heat-conducting oil flows back into the heating tank 91 to be reheated. In this way, the heated oil flowing into and out of the roller 3 can heat the roller 3. Since the roller 3 is heated, the copper bar is relatively easier to be flattened by heat. In the temperature control circuit, when the temperature in the heating tank 91 is lower than 200°C, the internal contact of the temperature control switch W is closed. In this way, the relay J1 is powered on to close the control power input end and the normally open contact end, the electric heating tube RT is powered on to heat the heat-conducting oil in the heating tank 91; when the temperature in the heating tank 91 is higher than 200°C, the internal contact of the temperature control switch W is open. In this way, the relay J1 is not powered on to close the control power input end and the normally open contact end, and the electric heating tube RT is not powered on to heat. Through the above, in the application of the new type, after the worker places the copper bar to be processed between the two rollers, the heated roller can effectively flatten the bent part and the concave or convex part of the heated copper bar, thereby bringing convenience to the worker, reducing the labor intensity of the worker, and correspondingly improving the work efficiency. Figure 3In the middle, relay J1 model is DC12V; electric heating tube RT is annular stainless steel armored dry burning type electric heating tube product with power 5KW; power module U1 is AC220V to DC12V switching power module product; temperature control switch W is KSD301 type temperature 200°C normally closed contact type latching temperature switch; electromagnetic valve DC1, DC2 is normally closed valve core electromagnetic valve with power 2W; hot oil pump M is high temperature heat conduction hot oil pump (800W) with model RY20; motor speed reduction mechanism M1 is motor gear type reducer product with power 5KW; air release valve 93 is safety valve with model A27T-16.
