Description

Strip-shaped sheet metal bending machine

Technical Field

The utility model relates to the technical field of bending equipment, in particular to a strip-shaped sheet metal bending machine.

Background

The production of burglary-resisting doors requires the use of a large number of metal sheets, typically a burglary-resisting door can be up to two meters in height, and for some high-end doors or custom doors, can be up to three meters in height or even higher. In the production process, for example, the side edges or the side frames of the burglary-resisting door or the supporting parts in the middle and other sectional materials, the whole strip-shaped metal plate needs to be bent, and the crease direction is consistent with the length direction of the metal plate. Under such processing demands, conventional means are as follows: in the method, a feeding device is required to be arranged, and when the bending angle is large, the bending capability of a single press roller is weak, and a plurality of press rollers with different shapes are required to be arranged for gradual roll forming, so that the occupied area is increased. At present, the current common stamping and bending equipment can only be loaded with a shorter die, namely, the crease is shorter, so the application intends to propose an equipment scheme suitable for stamping and bending of the strip-shaped metal plate. In addition, the device should also meet the stamping and bending requirements of various types, because the production factory cannot customize the device for the processing requirements of one part only, but the stamping and bending requirements of various parts are met as much as possible.

Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

Referring to fig. 1-4, the utility model provides a strip sheet metal bending machine, which comprises a machine body 1. The machine body 1 is provided with a working table surface, and the working table surface is positioned in the middle of the machine body 1. Three hydraulic cylinders 2 are fixed at the top of the machine body 1, the hydraulic cylinders 2 are vertically arranged, piston rods extend downwards, and the hydraulic cylinders 2 are located right above the working table surface. The top of the machine body 1 is fixedly connected with a baffle 11, and the baffle 11 shields the hydraulic cylinder 2.

A supporting beam 3, a female die 5 and a male die 4 are arranged between the working table surface and the hydraulic cylinder 2. The male die 4 is arranged below the upper female die 5, and the opposite surface of the male die 4 and the female die 5 is a working surface. The male die 4 and the female die 5 are pressed up and down, so that the plate can be punched and bent.

The female die 5 is arranged on a workbench surface, limiting ribs 12 are arranged on two sides of the width direction of the female die 5, the limiting ribs 12 are fixed on the workbench surface, the limiting ribs 12 cling to the female die 5, and the female die 5 is fixed through jackscrews.

The male die 4 is fixed to the bottom of the support beam 3. The support beam 3 comprises a beam body 31 and a backing plate 32 arranged at the top of the beam body 31, wherein the backing plate 32 is horizontally arranged and fixedly connected with the end parts of the piston rods of the three hydraulic cylinders 2. The hydraulic cylinder 2 is actuated to drive the punch 4 up and down.

The fixing structure of the male die 4 and the supporting beam 3 comprises a first clamping block 6, a second clamping block 7, a connecting block 8 and a supporting block 9. First, the bottom of the beam body 31 and the top of the punch 4 are both of a stepped structure. The bottom surface and the side surface of the first clamping block 6 are tightly attached to the top of the male die 4; the top and side surfaces of the connection block 8 are closely attached to the bottom of the beam body 31. The top surface of the first clamping block 6 is propped against the beam body 31 at the same time, but the bottom surface of the connecting block 8 is spaced between the male dies 4. Further, the first clamping block 6 and the second clamping block 7 are respectively located at two opposite sides of the connecting block 8, and clamp the top of the male die 4 through bolt connection, and meanwhile, the bolts penetrate through the connecting plate, so that the first clamping block 6 and the connecting plate are connected into a whole. Further, a waist-shaped hole is provided in the connection block 8, the waist-shaped hole is horizontally provided, and the connection block 8 is fixedly connected with the beam body 31 by means of bolts penetrating through the waist-shaped hole. Further, the support blocks 9 are fixed to the beam body 31 by bolts, while the support blocks 9 compress the connection blocks 8 in the horizontal direction.

The first clamping block 6, the second clamping block 7, the connecting block 8 and the supporting block 9 form a mounting unit, and the supporting beam 3 and the male die 4 are connected through a plurality of mounting units.

The structure is characterized in that when the bolts connected between the first clamping block 6 and the second clamping block 7 are loosened, the clamping of the male die 4 is canceled, and then different male dies 4 can be replaced according to the needs, and the female die 5 can be replaced by matching with the male dies 4 because the female die 5 is also fixed by jackscrews on the limit convex ribs 12. Since there are a plurality of mounting units, the lengths of the male die 4 and the female die 5 can be adjusted according to the use requirement, and even if the male die 4 and the female die 5 are long-bar-shaped plate-shaped structural members, the supporting beam 3 and the plurality of mounting units can provide sufficient restraint and support for the male die 4 and fully connect the male die 4 with the supporting beam 3, as long as the lengths of the male die 4 and the female die 5 do not exceed the supporting beam 3. In this scheme, can directly punching press buckle to the sheet metal component of integration in the burglary-resisting door.

The relative distance between the connecting blocks 8 can be adjusted through the action of the waist-shaped holes, and the adjustment is carried out according to actual use requirements. As shown in the drawing, the punches 4 are preferably arranged at equal intervals in each of the connection blocks 8, and if a shorter die is replaced, the intervals between a plurality of connection blocks 8 used locally can be shortened.

The function of the supporting block 9 is to apply constraint to the connecting block 8, so that the acting force is prevented from being completely borne by the bolts in the waist-shaped holes, and the stability of the connecting block 8 is improved.
