technical field

The invention relates to a press brake, in particular to a heat and cold cycle press brake for metal plates.

Background technique

Some arc-shaped metal sheets or arc-shaped metal strips are often used in conventional machinery. Due to the small amount used, if a special press brake is used, not only the equipment cost is high, but also the workshop area is occupied, resulting in high production costs. However, the work efficiency of manual bending is low, and the processed parts are not standard. Therefore, in mechanical processing, a bending machine that can process both arc-shaped metal sheets and arc-shaped metal strips is needed.

For example, the application number is a hand-operated multifunctional press brake, including a transmission mechanism, a pressing mechanism, an arc-shaped metal plate pressing mechanism, an arc-shaped metal strip pressing mechanism and a workbench, a transmission mechanism, a pressing mechanism, an arc-shaped metal The plate pressing mechanism and the curved metal strip pressing mechanism are fixed on the workbench. Although the present invention is simple in structure, easy to manufacture, low in manufacturing cost, convenient to install, easy to operate, takes up little space, and is easy to use, the press brake cannot bend thicker plates because the driving force is manual.

Another example is the hydraulic press brake with application number 201610061844.6, which includes: a frame, the lower part of the frame extends forward from the work table, the work table is provided with a lower die, and the top of the frame is provided with a beam arm protruding forward. There is a pair of guide rails on the frame between the beam-lifting arm and the worktable, and the guide slots of the two vertically-set guide rails are set opposite to each other on the left and right; a bending cylinder is fixed on the beam-lifting arm, and the piston rod of the bending cylinder is downward. After stretching out the cantilever arm, it is connected with the large pallet. The bottom of the large pallet is equipped with an upper mold. The two sides of the large pallet are respectively movable and embedded in the guide grooves of the two guide rails. It can move up and down in the two guide rails, so that the upper mold and the lower mold can be closed or separated from each other. Although the present invention has the advantages of simple structure, low production cost, and can eliminate the gap between the guide rail and the large carriage by adjusting the position of the guide rail to improve the quality of the bent pipe, the cost is relatively high, and the bending can only be formed at one time, and The temperature treatment cannot be carried out according to the characteristics of the metal.

As shown in Figure 1, a metal plate heat-cooling cycle press brake of the present invention includes a plane seat 1 with a depression, a pair of columns 2 are arranged on the plane seat 1, and a Rotating shaft 3, rotating shaft 3 is perpendicular to column 2, rotating shaft 3 runs through the upper end of column 2, and rotates in the end of column 2, is provided with two screw rods 4 continuously on this rotating shaft 3, and the thread direction of two screw rods 4 is arranged oppositely, one The outside of the column 2 has a runner 5 connected to the rotating shaft 3, and turning the runner 5 can drive the rotating shaft 3 to rotate together;

The lower part of the rotating shaft 3 is provided with a lifting seat 6, and the lifting seat 6 is located at the lower position between the two screw rods 4. The two screw rods 4 are respectively provided with threaded cylinders 7, and the threaded cylinders 7 cooperate with the screw rods 4. Each threaded cylinder 7 There is a movable arm 8 between the lifting seat 6, one end of the movable arm 8 is hinged on the threaded cylinder 7, and the other end is hinged on the lifting seat 6, and the lifting seat 6 is provided with a corresponding The arc-shaped pressing surface 9 and the threaded cylinder 7 move relative to the screw 4. When the rotating shaft 3 rotates, the two screw rods 4 rotate accordingly. Since the two screw rods 4 have opposite thread directions, they cancel each other out when they rotate. Since the threaded cylinder 7 is jointly connected on the lifting seat 6, it cannot rotate, and can only be driven by the thread on the screw rod 4 to move on the screw rod 4, thereby realizing that the two threaded cylinders 7 can move towards each other and move away from each other at the same time. Since the height of the threaded barrel 7 is constant, the length of the movable arm 8 is constant. Therefore, after the threaded barrel 7 moves horizontally, the lifting seat 6 is pushed and pulled to lift, thereby realizing the lifting of the arc-shaped pressing surface 9.

The bottom of the runner 5 is provided with a stepper motor 10, and a transmission belt 11 is arranged between the runner 5 and the stepper motor 10. Realize automatic operation, accurately realize the pressing height of the arc-shaped pressing surface 9, the continuous pressing time, and the pressing speed, and can perform high-frequency pressing on the metal plate, repeatedly pressing and lifting the action, and at the same pressing force It can quickly change the arrangement of metal molecules, help the metal to deform, and maintain long-term metal deformation memory.

One gas nozzle 15 corresponds to a strip groove 12. Repeatedly In the process of pressing down, in order to speed up the deformation process of the metal, hot gas can be injected into the strip groove 12 to increase the temperature of the metal plate, and the arc-shaped pressing surface 9 maintains a high-frequency pressing action to accelerate the deformation of the metal plate, and then quickly presses the metal plate into the strip groove. Cool air is injected into 12. At this time, the arc-shaped pressing surface 9 maintains a downward pressure without rising action, giving the metal plate a continuous pressure-holding process, which is convenient for the metal to quickly deform and shape at low temperature, and accelerate the release of internal stress.

The plane seat 1 is provided with a slide rail, and the end of the column 2 is provided with a slide seat 16, and the slide seat 16 moves in the slide rail, and the slide rail and the strip groove 12 are perpendicular to each other in the plane direction.
