Abstract

The utility model relates to a semi-automatic hydraulic sheet-bending machine with two rollers. The bending part of the utility model is composed of an upper rigid roller and a lower elastic roller, one end of the rigid roller is provided with a floating cantilever, and the other end is provided with a swinging support. The rigid roller is rotated by the friction of the rigid roller and sheets when the sheets are bent, the contact pressure of two rollers can be adjusted by a loading oil cylinder, and workpieces can be automatically pushed out by a workpiece pushing sheet. The discharge and the unloading of the made pieces, etc. are all completed automatically except that the sheets are loaded by manpower, and the sheets are bent by the pressure stressed by the swinging support. The utility model has the advantages of compact structure, high processing precision, convenient operation, the capability of bending pieces of various standards with one machine, etc. The utility model is a bending device of high efficiency and high precision.

Description

Semi-automatic hydraulic sheet-bending machine with two rollers

At present, in China's mechanical processing industry, sheet metal is rolled into products such as garden tube or arc, generally all adopts three rolls plate bending machine to finish, it rolls low precision, and efficient is low.

The utility model overcomes above-mentioned deficiency, provides a novel hydraulic semi-automatic pair of roller rolling machine.It is fast that this machine rolls speed, and single-piece can be finished about 5 seconds.Roll the precision height, the no any cut in product surface.The two ends straight portion is short, 2～3 times of about thickness of slab.

Sheet metal is rolled into garden tube or arc, must make to be rolled sheet material one end generation flexural deformation, form certain radius of curvature, radius of curvature is stablized also to go down continuously, finish one and play flow shape process, will obtain needed desirable garden.

Key of the present utility model is the flexible multiple layer of the roller strap in two rollers.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is that two rollers roll job analysis figure.

Fig. 2 is the utility model structure chart.

With reference to accompanying drawing 1, two rollers are controlled up and down by vertical direction, rigid roller (1) is last, resilient roller (2) is following, when applying power P in vertical direction, the multiple layer of the rubber of resilient roller (2) (4) forms drafts β, produce local deformation, produce bounce-back simultaneously, i.e. counter-pressure is if it is crooked to rigid roller (1) one side to be rolled part (5) this moment, owing to be subjected to the restriction of rigid roller (1) curved surface, sheet material and rigid roller contact portion must form certain radius of curvature R, and under rubber multiple layer (4) thickness and roller core (3) diameter one stable condition thereof, the radius of curvature R size is relevant with pressure P, stable and drive resilient roller (2) when at the uniform velocity rotating when pressure P, the garden tube of curvature unanimity will be obtained,, just the different size product can be obtained as long as change the pressure P value.

With reference to accompanying drawing 2, the rotation of resilient roller (2) is driven by motor (18), by cycloidal planetary gear speed reducer (19), shaft coupling (20), gear (21) is delivered to the input of resilient roller (2), rigid roller (1) one end can move about in the supporting seat (22) that connects with lathe bed (11), frictional force reliable simultaneously and that sheet material produces is rotated, the other end is established swing and is supported (6), so that withdraw from product, swing is supported (6) by support arm (8), oscillating oil cylinder (9) connects together it by bearing pin (10), and link by bearing pin (10) and lathe bed (11) respectively, taper sheath (7) is housed in the support arm (8).Applying plastic force P realizes by being located at the following load cylinder (12) of resilient roller (2), the piston rod (13) of load cylinder (12) connects together with joist (15), be lined with sphere cushion block (14) therebetween, joist (15) holds up crossbeam (16) support slipper (17), and load cylinder (12) is fixed on the lathe bed (11).Push piece device (23) is located at supporting seat (22) top of rigid roller (1), and shape of a saddle push piece plate (28) falls it by adjustment screw rod (24) drive slide block (25) and rides on the rigid roller (1).Piston rod (27) on the push piece oil cylinder (26) drives push piece plate (28) will roll the part release along rigid roller (1).Change pressure P or conversion rigid roller (1) diameter or go up cover one external diameter and the corresponding heavy wall steel bushing of product size, just can roll the different size product at rigid roller (1).

The utility model complete machine is that hydraulic pressure is semi-automatic, and mode of operation is manually and automatically, can swing when automatic support, afterburning, roll, arrange support, off-load, move back action such as part and finish automatically, Hydraulic Station is established on the lathe bed side provides system pressure oil for complete machine.

The utlity model has compact conformation, easy to operate, good processing accuracy, a machine can roll the characteristics such as plurality of specifications product, is a high efficiency, the high-precision equipment that rolls.
