Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to operate three rolls plate bending machine.
The purpose of this utility model realizes by following technical proposals:
According to three rolls plate bending machine of the present utility model, comprise roller member, roller member under two sides, main drive, hydraulic means, frame, electrical control gear, it is characterized in that described frame is made up of forebay and afer bay, top roll and side lower roll two ends are bearing in respectively on forebay and the afer bay, top roll passes through hanger bearing, head-selecting body and spindle balance mechanism supports are on the frame of front and back, forebay is an enclosed construction, afer bay is the open-type structure, head-selecting body is linked on afer bay by a twisted axis, spindle balance mechanism is connected the preceding axle head front of top roll, head-selecting body connects one and plucks the hair oil cylinder, the two ends of both sides lower roll are equipped with bearing and bearing block, bearing block is connected with coupling spindle, and coupling spindle is connected with the lifting hydraulic jack.
Described electrical control gear comprises electric cabinet, the limit switch that is located at head-selecting body upset extreme position and reseting limit position that electric cabinet is connected therewith, be located at the rising extreme position of both sides lower roll and the limit switch of falling-threshold position, and the power supply control button of transmission device.
Described lifting hydraulic jack is provided with hydraulic control one-way valve, in the hydraulic means return line oil filter is housed, and heater and liquid level gauge, Pressure gauge are housed in the fuel tank.
Described head-selecting body oil cylinder is the oil cylinder that all there is the earrings bearing at two ends.
Described main drive comprises main motor-reducing gear, is contained in the pinion of its output axle head, the gear wheel of pinion therewith, and Large Gear Shaft During is roll shaft.
Described balanced controls front end is provided with a vertical adjusting leading screw.
Between the piston rod of described coupking shaft and lifting hydraulic jack for being threaded.
When adopting the utility model, before the start, the both sides lower roll is in low level, and steel plate is injected between the upper and lower roll, starts transmission device and lifting hydraulic means, carries out roll bending.The roll bending moulding is started later on and is plucked the hair oil cylinder, drives head-selecting body and is thrown off top roll and overturn 90 ° by the upright position, and this moment, top roll was hung on the forebay, simultaneously by institute of spindle balance mechanism balance, kept level.After the head-selecting body upset, the good cylindrical shell that curls can successfully take out from top roll, finishes a roll bending operation, and oil cylinder resets then, and veneer reeling machine is got back to SBR.Press stop button and can finish parking.
The utility model has the advantages that:
1, because main drive only need drive top roll rotates, thereby makes the whole transmission device structure obtain simplifying, reduced power consumption simultaneously, saved electric energy, be provided with and pluck the reliability service that head mechanism and spindle balance mechanism have then guaranteed veneer reeling machine.
2, owing to the extreme position in various motions all is provided with limit switch, guaranteed that handling safety is errorless.
3, owing in hydraulic means, be provided with oil filter, guaranteed that the mechanical admixture that produces owing to wearing and tearing in the hydraulic means can not enter fuel tank, guarantees that the work of oil cylinder is unaffected.Heater can guarantee that then equipment also can trouble-free operation in the season of cold.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, three rolls plate bending machine of the present utility model, comprise roller member 6, roller member 5 under two sides, main drive, hydraulic means, frame, electrical control gear, it is characterized in that described frame is made up of forebay 7 and afer bay 4, top roll and side lower roll two ends are bearing in respectively on forebay 7 and the afer bay 4, top roll passes through hanger bearing, head-selecting body 3 and spindle balance mechanism 9 are supported on the frame of front and back, forebay 7 is an enclosed construction, afer bay 4 is the open-type structure, head-selecting body 3 is linked on afer bay 4 by a twisted axis 2, spindle balance mechanism 9 is connected the preceding axle head front of top roll, head-selecting body 3 connects one and plucks hair oil cylinder 1, the two ends of both sides lower roll 5 are equipped with bearing and bearing block, and bearing block is connected with coupling spindle, coupling spindle be connected with the lifting hydraulic jack (Fig. 2).
Described electrical control gear comprises electric cabinet, the limit switch that is located at head-selecting body upset extreme position and reseting limit position that electric cabinet is connected therewith, be located at the rising extreme position of both sides lower roll and the limit switch of falling-threshold position, and the power supply control button of transmission device.
Described lifting hydraulic jack 14 is provided with hydraulic control one-way valve, in the hydraulic means return line oil filter is housed, and heater and liquid level gauge, Pressure gauge are housed in the fuel tank.
Described head-selecting body oil cylinder 1 all has the oil cylinder of earrings bearing for two ends.
Described main drive comprises main motor 11-gear 12, is contained in the pinion 13 of its output axle head, the gear wheel 8 of pinion 13 engagement therewith, and Large Gear Shaft During is roll shaft.
Described balanced controls 9 front ends are provided with a vertical adjusting leading screw 10.
Between the piston rod of described coupking shaft and lifting hydraulic jack for being threaded.
As an embodiment, the Hydraulic Station of hydraulic means is a Y106L-4, N=15KW, n=1458r/min, 63YCYG-LB oil pump work of driven by motor.Hoist cylinder diameter of phi 360mm, system pressure are 220kgf/cm
2, main driving motor power is 75KW, top roll rotational line speed 4.55m/min.
