Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 3, a swivel nut 13 on cover in the middle part of preset hydro-cylinder type four column press column 7, and guiding swivel nut 13 by feather key 12, swivel nut 13 is threaded with adjusting nut 11, and makes adjusting nut 11 and swivel nut 13 catch up with crossbeam 1 by trim ring 14 to keep synchronously promoting up and down.When overhead oil cylinder 9 lifts entablature 1 to certain altitude, by nut driving mechanism rotating adjusting nut 11, swivel nut 13 is slided up and down along column face under the guiding of guide pillar key 12, when suitable distance is adjusted in swivel nut 13 bottom surface and entablature 1 bottom surface, stop adjusting nut 11, by overhead oil cylinder 9 hydraulic action decline entablature 1, until column face is withstood in swivel nut 13 bottom surface, and hydraulic pressure pins, height of packing compact adjustment terminates.
Above-mentioned nut driving mechanism specifically has following four technical schemes:
1. as shown in Figure 4, nut driving mechanism is single chain drive-belt nut driving mechanism, it comprises motor 16, drive sprocket 17, initiatively chain 15, chain 18, drive sprocket 17 is connected by active chain 15 with adjusting nut 11, chain 18 is connected with four adjusting nuts 11, drive sprocket 17 is driven by motor 16, through active chain 15 drive sprocket adjusting nut 11, the adjusting nut 11 on four columns is driven to rotate by this adjusting nut 11 together through chain 18 again, thus the distance between change upper and lower mould, realize height of packing compact and regulate.
2. as shown in Figure 5, nut driving mechanism is Dual Drive chain nut driving mechanism.When forcing press type is larger, single chain drive-belt is long, and the degree of regulation of adjusting nut 11 can decline, and the punching precision of forcing press also can decline thus.For ensureing precision, also facilitate the independence of each adjusting nut to regulate simultaneously, Dual Drive chain nut driving mechanism is adopted to drive adjusting nut, it comprises two groups of driving mechanisms, often group driving mechanism comprises motor 16, drive sprocket 17, initiatively chain 15, motor 16 drive drive sprocket 17, drive sprocket 17 is connected with an adjusting nut 11 respectively by an active chain 15, drive two compound adjusting nuts 11 of sprocket wheel by two chains 15 by a motor 16 simultaneously, thus the distance between change upper and lower mould, realize height of packing compact and regulate.
When adjusting four nut 11 initial position height and be consistent, chain driven mould height regulating device can unload lower chain easily, manually rotates separately each nut to certain altitude, loads onto chain.The initial Adjustment precision of chain driven mould height regulating device height of nut limits by teeth number of sprocket.
3. as shown in Figure 6, nut driving mechanism is single driving worm and gear nut driving mechanism, it comprises motor 16, gear drive group unit 22, bevel gear commutation group unit 20, worm-and-wheel gear 19, adjusting nut 11, shaft coupling 21, motor 16 is connected by gear drive group unit 22, be connected with worm-and-wheel gear 19 after bevel gear commutation group unit 20 changes transmission direction again, then engaged with adjusting nut 11 by worm-and-wheel gear 19.By drive motors 16, gear drive group unit 22, waist type slot type shaft coupling 21, bevel gear commutation group unit 20, worm-and-wheel gear 19, motor driving torque is transferred to the compound adjusting nut 11 of worm gear, adjusting nut 11 is driven to rotate, thus the distance between change upper and lower mould, realize height of packing compact and regulate.
The Adjustment precision of above-mentioned its single nut of worm and gear nut driving mechanism is subject to the restriction of teeth number of sprocket unlike Chain conveyer, so Comparatively speaking its nut Adjustment precision is higher.
The mode of above-mentioned its connecting axle of shaft coupling is waist type slot type, and namely the connecting hole of mounting flange is mounting hole, can be meticulousr and adjust the position of each nut conveniently and independently, thus ensures the higher parallel accuracy of forcing press.
4. as shown in Figure 7, nut driving mechanism is Dual Drive worm and gear nut driving mechanism.The basis of Fig. 6 increases a drive motors, and omit bevel gear commutation group unit 20, directly drive worm-and-wheel gear by gear drive group unit 22, by two drive motors through gear drive group unit 22, by waist type slot type shaft coupling 21 Direct driver worm-and-wheel gear 19 by torque drive to worm gear compound nut 11, thus change the distance between upper and lower mould, realize height of packing compact adjustment, both degree of regulation was improved, again can adjusting nut separately.
When adjusting four nut 11 initial position height and be consistent, Worm-gear type mould height regulating device conveniently can separate shaft coupling 21, rotates each worm screw certain angle, makes four adjusting nut 11 height and positions consistent, then retightens shaft coupling 21.Owing to adopting waist type slot type shaft coupling, during worm screw adjustment, its anglec of rotation is unrestricted, and it is higher that four initial Adjustment precision of nut compare chain driven mould height governor motion.
