Abstract

The utility model relates to a follow-up roller way material support mechanism used for adjusting the height of sheet material in front and at rear of a pre-bending machine, comprising a base. The follow-up roller way material support mechanism is characterized in that the base is provided with a swing arm, and each swing arm is connected with left and right support seats by a rotating shaft; the left and the right support seats are respectively provided with a twisting shaft, the two ends of which are respectively and fixedly provided with a side beam, and front and rear follow-up rollers that are transversely distributed are installed on the two side beams by four bearing seats; furthermore, the base is provided with at least one set of driving mechanism which ensures the twisting shafts to do small angle rotation. The follow-up roller way material support mechanism solves the problem that the product quality is affected by gravity deformation of the sheet material when the sheet material is pre-bended by the pre-bending machine, so that the sheet material which is pre-bended has higher straightness and better quality after being molded.

Description

Servo-actuated roller-way material carrying mechanism

(1) technical field:

The utility model relates to the supporting use equipment of metal forming machinery in the mechanical engineering, is to be used for a kind of servo-actuated roller-way material carrying mechanism that slab height is adjusted in the prebending machine front and back.

(2) background technology:

At present, prebending machine is when the pre-bending plate, because of plate very long, prebending machine is very short, and the prebending machine working method is to drive down hydraulic oil cylinder driving, like this, plate deforms because of gravity in the course of the work, influence the quality and the yield rate of plate after the pre-bending,, prevent that with regard to a kind of mechanism of needs plate is out of shape because of gravity for reaching better pre-bending effect.

(3) summary of the invention:

The purpose of this utility model will solve prebending machine exactly when the pre-bending plate, and plate is out of shape because of gravity, influences the problem of product quality, and a kind of servo-actuated roller-way material carrying mechanism is provided.

Concrete scheme of the present utility model is: design has the steel construction base, it is characterized in that: left and right supporting base is housed on base, one swing arm is installed on left and right supporting base, each swing arm is connected with one by a rotating shaft and turns round axle, turn round a two ends and respectively be installed with a curb girder, the loose roll of two lateral arrangement in front and back is installed by four bearing blocks on two curb girders; And at least one cover is installed on base makes distortion make the driving mechanism of low-angle rotation.

For making the utility model when not working, overcome of the influence of the sagging gravity of curb girder and loose roll to driving mechanism, below two curb girders, two pedestals are being installed on the base in the utility model.

Being installed in described in the utility model to make on the base and turning round axle to make the driving mechanism of low-angle rotation can be fork driving mechanism or rack-and-pinion driving mechanism, can also be gear and other mechanism.

Fork driving mechanism described in the utility model includes and turns round the axle fork of fixedlying connected and be installed in oil cylinder on the base, and the push rod cup of oil cylinder is rotationally connected with fork employing bearing pin.

For satisfying the needs of the different thicknesss of slab of pre-bending, at the place ahead of cylinder putter head certain distance, the adjustable limiting device is installed in the utility model type, this adjustable limiting device includes limited block and and regulates bolt, regulates bolt and is installed on the nut seat on the base.

The utility model compact conformation, reliable operation is installed in the entrance end of prebending machine, can effectively solve the problem that plate deforms because of gravity, improves the quality and the yield rate of product.

(4) description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the A-A view of Fig. 1;

Fig. 3 is a vertical view of the present utility model.

Among the figure: the 1-loose roll, the 2-bearing block, 3-turns round axle, 4-curb girder, 5-pedestal, 6-supporting base, the 7-driving mechanism, 8-rotating shaft, 9-swing arm, 10-holder, 11-oil cylinder, 12-push rod cup, the 13-fork, the 14-bearing pin, the 15-limited block, the 16-nut seat, 17-regulates bolt, 18-base.

(5) specific embodiment:

Referring to Fig. 1,2,3, the utility model adopts steel construction to make rectangular base 18, particularly: left and right supporting base 6 is housed on base 18, on left and right supporting base 6, be equipped with one and turn round axle 3, turn round axle 3 two ends and respectively be installed with a curb girder 4, the loose roll 1 of two lateral arrangement in front and back is installed by four bearing blocks 2 on two curb girders 4; And two covers are installed on base make and turn round the driving mechanism 7 that axle is done low-angle rotation, and, promptly constitute the utility model over against two pedestals 5 of two curb girders, 4 belows.

Be installed in described in the utility model to make on the base 18 and turn round axle 3 to make the driving mechanisms 7 of low-angle rotation be to adopt fork driving mechanism (can also adopt driving mechanisms such as gear or rack-and-pinion certainly), described fork driving mechanism is referring to Fig. 2, it includes and turns round axle 3 forks of fixedlying connected 13, with the oil cylinder 11 (installing by holder 10) that is installed on the base 18, the push rod cup 12 of oil cylinder 11 adopts bearing pin 14 to be rotationally connected with fork 13.And also at the place ahead of cylinder putter head 12 certain distance, stopping means is installed in the utility model, this stopping means includes limited block 15 and and regulates bolt 17, regulates bolt 17 and is installed on the nut seat 16 on the base 18.

Operation principle of the present utility model is: under the control of hydraulic pressure assembly, and oil cylinder 11 work, its push rod cup 12 promotes forks 13 to be made and turns round axle 3 and rotate, and turns round axle 3 and drives swing arms 8 and make the loose roll 1 support plate that moves up and down by rotating shaft 8, curb girder 4, bearing block 2 again; Its stroke can be regulated by limited block 15.Front and back end loose roll 1 is when the support plate, because curb girder 4 is to be rotationally connected with rotating shaft 8, thus the inclination needs can adapt to Sheet Metal Processing preferably the time, thus the pre-bending quality guaranteed preferably.
