Embodiment 1

[0022] Such as figure 1 As shown, the three-roller plate bending machine with horizontally adjustable center distance of the lower rollers includes a bed 6, a frame 18, an upper roller 19, a lower roller device, a back-up roller device, a main transmission mechanism 20, and a lower roller horizontal driving device 17 , the lower roller device includes a lower roller 1, a lower roller bearing seat 16, the two ends of the lower roller 1 are fixedly connected with the lower roller bearing seat 16 by bearings, and there are 2 lower rollers 1; 2 lower rollers 1 are provided with 1-10 A set of back-up roll devices, each set of back-up roll devices consists of two back-up roll devices and are respectively located below the two lower rolls 1; each back-up roll device includes 1 or 2 back-up roll bearing housings 3, 2 or 1 Back-up roll 2; when there is one back-up roll bearing seat 3 (the back-up roll is a cantilever beam), two back-up rolls 2 are fixed on the back-up roll chock 3, an...

Embodiment 2

[0025] Such as image 3 As shown, the center distance level adjusting device is a hydraulic device, the plunger 5 of the hydraulic cylinder of the hydraulic device is fixed on the support 7 by a nut 9, and the support 7 is fixed on the bed 6 by bolts and keys. The bearing seat 3 also serves as the cylinder body of the horizontally driven plunger cylinder. The plunger 5 passes through the guide sleeve 4, and the guide sleeve 4 is fixed on the cylinder body. Under the action of the plunger cylinder, the convexity of the lower roller in the horizontal direction can be adjusted to withstand Horizontal force. Hydraulic devices are all provided on the 2 back-up roll chocks 3 of each set of back-up roll devices.

[0026] If the guide sleeve 4 is changed into a nut, the plunger 5 is changed into a rotatable screw rod, which can become a horizontal mechanical driving device. The dust cover between the back-up roller chocks and the plunger is not shown.

Embodiment 3

[0028] Such as Figure 4 As shown, the center distance level adjustment device is a nut 9, a screw 10, and an adjustment block 11. The two support roller bearing seats 3 of each set of support roller devices are provided with screw through holes, and the screw rod 10 runs through the two support rollers. The screw through hole of the bearing seat has a flange head at one end, and the other end is threaded and screwed with a nut 9. The tightness of the nut 9 is at the outer end of the support roller bearing seat 3. There are four adjusting pads 11, which are U-shaped and open. Facing down, the adjusting spacer 11 is inserted on the screw rod 10. After the nut 9 is loosened, it is not necessary to withdraw from the screw rod. The position of the adjusting spacer 11 can be adjusted arbitrarily, and the center distance L of the lower roller can be changed. If the thickness of the four adjusting spacers is the same, the lower roller The center distance L has five gears.

Abstract

A three-roller plate bender with horizontally adjustable central distance between lower rollers is composed of main body, machine frame, upper roller, lower roller unit, master drive mechanism and horizontal drive unit for lower roller. Said lower roller unit consists of two lower rollers, bearings and their holders, 1-10 sets of 2 supporting rollers under two lower rollers and relative bearing sets, and horizontal regulators of central distance (one for each set of a supporting rollers).

Description

technical field [0001] The invention relates to a three-roller plate bending machine, which is a forging equipment for bending metal plates, in particular to a three-roller plate bending machine whose center distance between two lower rolls can be adjusted in the horizontal direction. Background technique [0002] The existing three-roller plate bending machine with adjustable center distance between the two lower rollers in the horizontal direction has two types. One is that the lower roller has no support roller, and the two lower rollers are adjusted in the horizontal direction by two sets of hydraulic or mechanical drive devices. The center distance of the lower rollers, and control the parallelism of the two lower rollers. The advantage of this form is that it is easy to adjust, and it is stepless adjustment; the disadvantage is that the parallel accuracy of the two rollers is poor, the errors of the two sets of driving devices may be superimposed in the same direction,...
