Abstract

The invention discloses a three-roller plate bending machine, and belongs to the field of the machine manufacturing. The three-roller plate bending machine comprises a base, left and right brackets, an upper roller, two lower rollers and a reducing mechanism; two lower rollers are installed between the left and right bracket, two lower rollers are parallel mutually, and two lower rollers are connected with the reducing mechanism; the upper roller is installed above the lower rollers; the tops of the left and right brackets are respectively provided with hydraulic cylinders; two ends of the upper roller are respectively connected with two hydraulic cylinders; two hydraulic cylinders drive the upper roller to be moved upwards and downwards; the outer side of the lower rollers is provided with an assistant support roller; the assistant support roller is installed on a guide rail connected between the left and right brackets, and slid along the guide rail. Through the assistant support roller installed at the outer side of the lower rollers, a winding roller can be assisted to execute the dynamic support control to the plate in the winding process, and the winding roller is prevented to generate the pull force by the dead weight, so that the winding efficiency and precision are affected; and the assistant support roller can be moved along the guide rail so as to meet the winding requirements of different types of the plates.

Description

Three rolls plate bending machine

Technical field

The present invention relates to a kind of veneer reeling machine, be specifically a kind of three rolls plate bending machine, belong to mechanical manufacturing field.

Background technology

Veneer reeling machine carries out the bending moulding lathe of continuity point to sheet material, has the function of the difformity sheet materials such as the O type that rolls, U-shaped, multistage R.The field difference of veneer reeling machine owing to using, kind is also different, is divided into three rolls plate bending machine and four-roll plate bending machine from roller number.Existing three rolls plate bending machine controls sheet material by means of only winding up roller itself in coiling process, and because sheet metal deadweight is heavier, easily form lower pulling force to winding up roller at coiling process, what reduce veneer reeling machine rolls efficiency, affects the precision of final finished.

Summary of the invention

Technical problem to be solved by this invention is to overcome prior art defect, provides the three rolls plate bending machine that effectively can carry out support and control in a kind of coiling process to sheet material.

In order to solve the problems of the technologies described above, three rolls plate bending machine provided by the invention, comprises base, left and right support, top roll, two lower rolls and reducing gear, and install two lower rolls between the support of described left and right, two lower rolls parallel, and two lower rolls are connected with reducing gear; Above described lower roll, top roll is installed; Hydraulic cylinder is installed respectively in the top of left and right support, two hydraulic cylinders in two ends and difference of top roll are connected, and two Driven by Hydraulic Cylinder top rolls run up and down, and the outside of described lower roll is provided with supplemental support roller, described supplemental support roller is installed on the guide rail that is connected between the support of left and right, along slide.

In the present invention, described supplemental support roller comprises slide block, be arranged on movable block inside slide block and expansion screw, is provided with multiple circle and rolls bar inside described movable block; Described expansion screw is connected with movable block through the silk hole on slide block.

In the present invention, the support between described top roll and lower roll is provided with spacing pulley.

Beneficial effect of the present invention is: (1), by being arranged on the supplemental support roller outside lower roll, winding up roller can be assisted in coiling process to carry out dynamic support control to sheet material, and avoid its deadweight to produce to pull to winding up roller and draw, impact rolls efficiency and precision; Supplemental support roller can move along guide rail, rolls requirement with what adapt to different model sheet material; (2) the multiple circles, in coiling process in movable block roll bar in company with sheet material-rolling, continue to be formed sheet material to support, and improve support effect; (3) support, between top roll and lower roll is provided with spacing pulley, avoids sheet material in coiling process to depart from.

Accompanying drawing explanation

Fig. 1 is three rolls plate bending machine structural representation of the present invention;

Fig. 2 is supplemental support roller sectional view of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in further detail.

As shown in Figure 1, a kind of three rolls plate bending machine of the present invention, comprises base 1, left and right support 5, top roll 9, two lower rolls 8, reductor 4, drive motors 3 and control cabinets 2.Left and right support 5 is fixed on base 1, and install two lower rolls, 8, two lower rolls 8 between left and right support 5 and parallel setting, the right-hand member of two lower rolls 8 is connected with reductor 4, and reductor 4 is connected with drive motors 3 output shaft, and drive motors 3 is electrically connected control cabinet 2.

Top roll 9 is installed in the top of two lower rolls 8, hydraulic cylinder 6 is installed at the top of left and right support 5 respectively, hydraulic cylinder 6 is installed downwards, the piston-rod lower end connection sliding block (not shown) of hydraulic cylinder 6, the two ends of top roll 9 are connected with the slide block of two hydraulic cylinder 6 upper piston rod lower ends respectively, and two hydraulic cylinders 6 drive top roll 9 to run along left and right support about 5.Support between top roll 9 and lower roll 8 is provided with spacing pulley, for controlling sheet material in coiling process, prevents from departing from.

As shown in Figure 2, be provided with supplemental support roller 8 in the outside of lower roll 8, supplemental support roller 8 is installed on two guide rails 7 being connected between left and right support 5, can slide along guide rail 7.Supplemental support roller 8 comprises slide block 8-1, be arranged on movable block 8-2 inside slide block and expansion screw 8-4, and be provided with 4 circles inside movable block 8-2 and roll bar 8-3, it is parallel with lower roll 8 that circle rolls bar 8-3, can rotate.Slide block 8-1 side is provided with two through holes, so that two guide rails 7 pass.Slide block 8-1 front is provided with a hole, and expansion screw 8-4 is connected with movable block 8-2 through the silk hole on slide block, and rotary extension screw rod 8-4 drives movable block 8-2 to run back and forth to lower roll 8 direction, realizes supporting to sheet material.

The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
