Description

sheet metal bending machine

technical field

The invention relates to a sheet metal bending machine for bending sheet metal or strips.

Background technique

The bending machine is divided into manual bending machine, hydraulic bending machine and CNC bending machine. Manual bending machine is divided into mechanical manual bending machine and electric manual bending machine, and hydraulic bending machine can be divided into synchronous mode: torsion shaft synchronous, machine-hydraulic synchronous, and electro-hydraulic synchronous. According to the movement mode, the hydraulic bending machine can be divided into: up-moving type and down-moving type. The metal plate bending machine referred to in this patent refers to an electric manual bending machine, which is an improvement on the electric manual bending machine.

The traditional electric manual bending machine includes a base, a slide rail and a fixed block are arranged on the base, a slide block is arranged on the slide rail, a driving device is connected to the slide block, and a first bending surface is provided at one end of the slide block. The fixed block is provided with a second bending surface, and the first bending surface and the second bending surface cooperate to bend metal plates or metal strips, etc. When in use, a metal plate or metal strip is inserted between the sliding block and the fixed block , the sliding block of the driving device is started to hit the fixed block, and the bending of the metal plate or metal strip is realized according to the bending shape of the first bending surface and the second bending surface, but the first bending surface and the second bending surface of this bending machine The second bending surface has a fixed bending angle and shape, so to change the bending angle, the sliding block and the fixing block need to be replaced, so it is troublesome to use, and if the bending angle is changed, it is necessary to prepare multiple fixing blocks and multiple Fixed blocks, thus causing waste of material.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a metal plate bending machine, which can be applied to bending operations with different bending angles and can also reduce the use cost.

In order to solve the above technical problems, the present invention is solved by the following technical solutions: a metal plate bending machine, including a base, a slide rail and a fixed block are arranged on the base, a slide block is arranged on the slide rail, the The sliding block is connected with a driving device, one end of the sliding block is provided with a first mounting groove, the fixed block is provided with a second mounting groove, and a set is provided between the first mounting groove and the second mounting groove There is a bending mold, and the bending mold is formed by splicing several modules with different bending angles. In this way, the front and back modules in the bending mold can be connected. When the bending angle needs to be changed, it is enough to splice the modules on one side to the other side. The original splicing surface is used as the bending surface, so that A bending tool can bend different angles.

In the above technical solution, preferably, each module is provided with a protrusion on one side and a groove on the other side, the protrusion is provided with a first screw hole, and the groove is provided with a second screw hole. holes, the protrusion of any one of the modules can cooperate with the groove of one of the modules so that the first screw hole and the second screw hole are coaxial. The first screw hole and the second screw hole can be fixed by bolts. When in use, the first screw hole and the second screw hole on both sides of the bending surface to be used are not fixed by bolts, and the rest of the modules are fixed by bolts.

In the above technical solution, preferably, the protrusion and the groove are arranged at the lower part of the module, and the two sides of the sliding block are provided with retaining strips, and the height of the retaining strip is higher than that of the protrusion on the module. high. Arranging the bumps and grooves at the lower part of the module can enable the bending machine to bend metal plates with a higher height, and setting the stop bar can prevent the cooperation between the bumps and the grooves from affecting the bending of the plate body.

Compared with the prior art, the present invention has the following beneficial effects: the modules in the bending die of the present invention can be connected front and back, and when the bending angle needs to be changed, it is enough to splice the modules on one side to the other side. The original splicing surface is used as the bending surface, so that a bending mold can bend different angles, save space, save material, and be easy to operate.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments: Referring to Figures 1 to 3, a sheet metal bending machine includes a base 1 on which a slide rail 2 and a fixed block 3 are arranged. A sliding block 4 is arranged on the slide rail 2, and a driving device 5 is connected to the sliding block 4. In this embodiment, the driving device 5 may be an air cylinder, a hydraulic cylinder, etc., and one end of the sliding block 4 is provided with a first Mounting groove 41, the second mounting groove 31 is provided on the fixed block 3, and a bending die 6 is arranged between the first mounting groove 41 and the second mounting groove 31, and the bending die 6 consists of several Modules 7 with different bending angles are spliced together, three in the present embodiment. In this way, the modules 7 in the bending die 6 can be connected front and back. When the bending angle needs to be changed, it is enough to splice the modules 7 on one side to the other side, and use the original splicing surface as the bending angle. surface, so that a bending die 6 can bend different angles.

Each module 7 is provided with a protrusion 71 on one side and a groove 72 on the other side, the protrusion 71 is provided with a first screw hole 73, and the groove 72 is provided with a second screw hole 74 The protrusion 71 of any one of the modules 7 can cooperate with the groove 72 of one of the modules 7 so that the first screw hole 73 and the second screw hole 74 are coaxial. The first screw hole 73 and the second screw hole 74 can be fixed by bolts 9. When in use, the first screw hole 73 and the second screw hole 74 on both sides of the bending surface to be used are not fixed by bolts 9, and the remaining modules 7 All adopt bolt 9 to fix between.

The protrusion 71 and the groove 72 are arranged on the lower part of the module 7, and the sliding block 4 is provided with stop bars 8 on both sides, and the height of the stop bars 8 is higher than that of the protrusion 71 on the module 7. high. Setting the bump 71 and the groove 72 at the lower part of the module 7 can enable the bending machine to bend a metal plate with a higher height, and setting the stop bar 8 can prevent the bump 71 from matching the groove 72 against the plate body Bending affects.
