Abstract

The invention relates to a novel three-roll plate bending machine which is characterized in that two lower rolls are respectively arranged on a swing module; the base of the swing module is a reinforcing beam; the lower rolls and a carrier roller device are arranged on the reinforcing beam; a swing hinged seat is arranged below the reinforcing beam; two lower roll swinging modules are arranged on the same foundation in a hinged joint way; positions of the lower roll swinging modules are symmetrical to an up-and-down moving track plane of an upper roll centre line; the swing of the lower roll swinging modules is controlled by an oil cylinder; the two lower rolls can be swung arbitrarily to ensure that the mutual centre distance can be regulated; and the two lower rolls are always supported by a carrier roller at the same time. The novel three-roll plate bending machine is capable of increasing the plate bending accuracy and the plate bending ability and expanding the use range on the premise of not increasing the cost.

Description

Novel three rolls plate bending machine

Technical field

The present invention relates to a kind of forging machine tool equipment, especially veneer reeling machine.

Background technology

At present, in the known three rolls plate bending machine, there are a kind of two lower rolls to be mounted on the same base; The position is changeless, and its major advantage is that two lower rolls can rely on base to implement carrying roller and support; Its rigidity of lower roll that has carrying roller to support is best; Can effectively improve the roll bending precision and reduce investment outlay, its major defect is that two lower roll centre-to-centre spacing are fixing dead, and the centre-to-centre spacing size is non-adjustable; The veneer reeling machine of this type is domestic to be called " top roll universal veneer reeling machine ", and domestic production producer is numerous specifically not to be enumerated; It is unfixed that a kind of two lower rolls are arranged, and on guide rail, can move horizontally individually or simultaneously, and its major advantage is; Two lower roll centre-to-centre spacing are adjustable, when centre-to-centre spacing strengthens, with onesize top roll plus-pressure; Can roll thicker steel plate, can roll up the circle than minor diameter when centre-to-centre spacing reduces, its major defect is; Because two lower rolls are unfixed with respect to base, can't obtain carrying roller and support.This veneer reeling machine is domestic to be called " horizontal downward-adjusting type lapping machine ", and famous brand has " MAV " veneer reeling machine of Italian DAVI company etc.Lower roll has carrying roller to support and the lower roll adjustable center distance; This is two extraordinary functions, does not have a kind of veneer reeling machine to possess this two functions all over the body unfortunately, or has adjustable lower roll centre-to-centre spacing; But two lower rolls just can not get carrying roller to be supported; Two lower rolls can obtain carrying roller and support, but two lower roll centre-to-centre spacing are just non-adjustable, the present situation of Here it is countries in the world veneer reeling machine.

Summary of the invention

In order to change the deficiency of the above-mentioned present situation of veneer reeling machine, the present invention provides a kind of novel three rolls plate bending machine, and two lower rolls of this veneer reeling machine can change centre distance to each other, can obtain the support of carrying roller again all the time.

The technical solution adopted for the present invention to solve the technical problems is: novel three rolls plate bending machine is by top roll, and lower roll swing chunk is swung hinged seat, and oil cylinder is controlled in swing; Base, left frame, right frame, top roll left end pressurization oil cylinder; Top roll right-hand member pressurization oil cylinder, top roll left end overturning bearing body, overturning oil cylinder, top roll right-hand member bearing body; The top roll Power Component, the lower roll Power Component is formed, and it is characterized in that: two lower roll swing chunks respectively are installed on the base with the swing hinged seat; The position is symmetrical in the top roll center line and moves up and down trajectory plane, controls oil cylinder with swing and controls the swing of lower roll swing chunk, to change the centre-to-centre spacing between two lower rolls; Lower roll is swung chunk by lower roll, lower roll left end shaft bearing, lower roll right-hand member bearing block; Buckstay, support roller device is swung hinged support member; The oil cylinder Connection Block is formed; It is characterized in that: lower roll is fixed on the buckstay upper surface through its left and right two end axles bearing, and support roller device is installed in the middle of two bearing blocks of buckstay upper surface, swings hinged support member and is fixed on the buckstay lower surface.

The invention has the beneficial effects as follows that two lower rolls can be swung arbitrarily to regulate centre distance each other, two lower rolls can both obtain carrying roller all the time and support.Novel three rolls plate bending machine both can improve the roll bending precision under the prerequisite that does not raise the cost, can improve the roll bending ability again and enlarge the scope of application.

The specific embodiment

In Fig. 1 embodiment, lower roll swing chunk (5) is installed on the base (12) with swing hinged seat (13).Lower roll is swung between the certain activity of chunk and left frame (2) and right frame (11) maintenance, not hinder the swing of lower roll swing chunk.Top roll right-hand member pressurization oil cylinder (7) drives top roll right-hand member bearing body (8) and moves up and down at right frame (11) slideway place.Top roll left end pressurization oil cylinder (1) is connected in hinged way with top roll left end overturning bearing body (4) and drives it through its piston rod earrings (15) and moves up and down at left frame (2) slideway place.Top roll left end overturning bearing body (4) can by with 90 ° of the shared jointed shaft overturnings of oil cylinder piston bar earrings.Select top roll to drive as required, or lower roll drives, or up-down rollers all drive.

In Fig. 2 embodiment, two oil cylinder Connection Blocks (25) can be fixed on buckstay (22), and the position can be at lower roll right-hand member bearing block (21), in the middle of the space of support roller device (23) and lower roll left end shaft bearing (26).The position of three hinged support members of swing (27) preferably is aligned in the lower roll right-hand member bearing block of installing above the buckstay (21) respectively, support roller device (23) and lower roll left end shaft bearing (26) below the buckstay.The buckstay cross sectional shape can the side of being, can be other shapes also, as long as enough torsional rigidities and local compressive resistance are arranged.
