Abstract
A hydraulic punching machine comprises a base, an upper beam supported on the base through an upright post, and a sliding block; the sliding block is guided through guide rails fixed on the upright post on the left side and the right side; an oil cylinder is vertically fixed above the upper beam; a piston rod of the oil cylinder is connected with a small sliding block; the small sliding block is vertically guided in the upper beam; a left linkage mechanism and a right linkage mechanism are arranged between the upper beam and the sliding block; the left and right linkage mechanisms have the same mechanism, are symmetrically arranged and comprise an upper connecting rod and a lower connecting rod which are mutually hinged; the upper end of the upper connecting rod is hinged on the upper beam; the lower end of the lower connecting rod is hinged on the sliding block; one end of a middle connecting rod is hinged on the small sliding block; the other end of the middle connecting rod is hinged with a hinge point of the upper connecting rod and the lower connecting rod; and the sliding block synchronously drives the left and the right linkage mechanisms to swing. The hydraulic punching machine has the advantages of simple structure, low guiding requirement, multi-point synchronous force application, lowered requirement of the strength of the sliding block and the machine body, and low cost, and is particularly suitable for demands of the ordinary and common pressworking process.
Description
Technical field
The utility model relates to a kind of general large-scale pressworking equipment, especially hydraulic press.
Background technology
Pressure processing is a kind of common, mechanical processing technique widely, to the renewal of pressworking equipment with improve and will produce huge and far-reaching influence to socio-economic development.
Existing common general pressworking equipment has following a few class: 1, mechanical crank forcing press.2, hydraulic press (hydraulic press or hydraulic press).3, hammer class (pneumatic hammer, machine hammer).4, friction press.
Hydraulic press is a kind of a kind of novel pressure process equipment between mechanical crank forcing press and hydraulic press, and its pressure source is a hydraulic jack.
At present, occurred adopting hydraulic cylinder directly to be connected the forcing press of driving with slide block, the forcing press of this mode, the power of sending when a high position is the same big with near the lower dead center power, less pressure can only be provided, not meet common, common pressure processing craft demand.
Summary of the invention
The utility model proposes a kind of hydraulic press, be particularly suitable for common, common pressure processing craft demand, it is simple in structure simultaneously, cost is low.
For this reason, the technical solution of the utility model is: a kind of hydraulic press, comprise base, by upper beam, the slide block of upright supports on base, slide block leads by the guide rail that and arranged on left and right sides is fixed on the column, it is characterized in that: oil cylinder vertically be fixed on upper beam directly over, the piston rod of oil cylinder is connected with small slide block, and small slide block leads up and down in putting the beams in place; Be provided with left and right linkage between upper beam and slide block, the mechanism of left and right linkage is identical, and symmetric arrangement, constitute by last connecting rod and lower link, be hinged between last connecting rod and the lower link, the upper end of last connecting rod is hinged on the upper beam, and the lower end of lower link is hinged on the slide block; One end of intermediate connecting rod is hinged on the small slide block, and the other end of intermediate connecting rod is hinged on the pin joint of connecting rod and lower link, and slide block drives left and right linkage swing synchronously.
To further improvement in the technical proposal, between upper beam and slide block, be provided with slide block lower dead center guiding mechanism.
Beneficial effect: the utility model is by the hydraulic oil cylinder driving small slide block, small slide block driven in synchronism left and right sides linkage, drive the motion of slide block by left and right sides linkage, the strength of sending when a high position is less, approaching with oil cylinder power, and strength is very big near lower dead center, is 10 to 20 times of oil cylinder power, this mechanical characteristic is particularly suitable for common, common pressure processing craft demand, as blanking, deburring, punching, press-bending, shaping, correction, the shaping of cold punching technology; Cold-heading and hot forging etc.Because the hydraulic press drive mechanism is simple, guiding requires low, the synchronous application of force of multiple spot to reduce the requirement of strength to slide block and fuselage, cost is low simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, it is as follows to further describe the utility model: a kind of hydraulic press, comprise base 7, be supported on upper beam 1 and slide block 6 on the base by column 3, slide block 6 leads by the guide rail 4 that and arranged on left and right sides is fixed on the column, oil cylinder 11 vertically be fixed on put the beams in place 1 directly over, the piston rod of oil cylinder is connected with small slide block 12, and small slide block 12 leads up and down in putting the beams in place; Be provided with left and right linkage between upper beam 1 and slide block 6, the mechanism of left and right linkage is identical, and symmetric arrangement; Left side linkage is made of last connecting rod 9 and lower link 8, is hinged between last connecting rod 9 and the lower link 8, and the upper end of last connecting rod 8 is hinged on the upper beam 1, and the lower end of lower link 8 is hinged on the slide block 6; Right connecting rod mechanism is made of last connecting rod 2 and lower link 5, is hinged between last connecting rod 2 and the lower link 5, and the upper end of last connecting rod 2 is hinged on the upper beam 1, and the lower end of lower link 5 is hinged on the slide block 6; One end of intermediate connecting rod 13 is hinged on the small slide block 12, and the other end of intermediate connecting rod 13 is hinged on the pin joint of connecting rod 2 and lower link 5 and goes up on the pin joint of connecting rod 9 and lower link 8, the left and right linkage swing of small slide block 12 drive synchronously.
Hydraulic press shown in Figure 1 because left and right sides connecting rod swing is synchronous, can guarantee that slide block makes the characteristic of parallel motion so this structure except that the basic mechanical characteristic with hydraulic press, also has; This specific character is extremely important, because actual suffered load usually is eccentric in the work of press slide block, for guaranteeing that slide block can also be done parallel motion when the load that is subjected to, the slider guide guide rail of existing press is all very long, also wants the limit load offset; This has strengthened the device fabrication cost undoubtedly, has limited the press scope of application; The mechanical characteristic of the synchronized parallel movement of this hydraulic press has overcome this problem preferably, and this structure is one of primary structure of middle work top hydraulic press.
