Description

Technical Field

[0001] The utility model belongs to the technical field of plate bending, in particular to a plate bending machine. Background Art

[0002] Sheet metal bending is a common metal processing technology. It mainly uses equipment such as bending machines to bend and deform metal sheets to form components with certain angles and shapes.

[0003] For example, the Chinese patent with publication number CN207343508U discloses a sheet metal bending machine, including a machine body, a first power assembly, an upper mold driven by the first power assembly to vertically lift and lower mold for punching with the upper mold, the machine body includes an upper workbench and a lower workbench, the first power assembly is arranged on the upper workbench, the upper mold is arranged at the lower end of the first power assembly; the lower mold is arranged on the lower workbench; and also includes a second power assembly that drives the lower mold to move horizontally and position, the second power assembly is arranged on the lower workbench. The second power assembly of the utility model is arranged on the lower workbench, and the second power assembly can not only drive the lower mold to move horizontally on the lower workbench when working, so as to realize the rapid installation of the lower mold and save labor costs; but also can realize the positioning of the lower mold when not working, so as to avoid the lower mold being shaken or moved by the impact of the upper mold, which affects the accuracy of the workpiece.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: when the device is bending the sheet, some rust will exist on some sheets, and during the bending process, some rust will fall into the lower mold. If more rust accumulates together, it will affect the bending of the sheet, so it needs to be cleaned manually, which is inconvenient. In addition, when installing the lower mold, the device needs to push the lower mold onto the screw rod by hand. During the pushing process, the screw rod is in a rotating state. If a person accidentally touches the screw rod, it will cause injury. This process has certain safety hazards. In view of this, we propose a sheet metal bending machine. Utility Model Content

[0006] The purpose of the utility model is to provide a plate bending machine to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a sheet metal bending machine, comprising:

[0008] A workbench, a sliding groove is provided on the top of the workbench, a discharging groove is provided at the bottom of the sliding groove, a placing groove is provided at the bottom of the discharging groove, a collecting box is provided in the placing groove, a plurality of limit grooves are provided at the bottom of the sliding groove and on both sides of the discharging groove, a lower pressing plate is provided in the sliding groove and on both sides of the discharging groove, a plurality of springs fixed to the inner wall of the sliding groove are fixedly installed on the top of the lower pressing plate, a lower mold is provided in the sliding groove and between the two lower pressing plates, and limited blocks are fixedly installed on both sides of the lower mold and at the bottom of the two lower pressing plates, one end of the limit block extends into the corresponding limit groove, and a through groove connected with the discharging groove is provided in the lower mold;

[0009] An L-shaped plate is fixedly mounted on the top of the workbench. Two hydraulic cylinders are fixedly mounted on the top of the L-shaped plate and directly above the sliding groove. The output shafts of the two hydraulic cylinders both pass through the top of the L-shaped plate and are fixedly mounted with an upper mold.

[0010] When the lower mold is moved to the left side of the workbench, the two limit blocks on both sides of the lower mold will squeeze the lower pressure plate to move upward. At this time, the springs will be squeezed and will shrink. Then, the lower mold will drive the limit blocks on both sides to move in the sliding groove. While moving, the staff will lift the lower mold to ensure that one end of the two limit blocks can be located above the limit groove, so that the lower mold can move normally. Then, when the lower mold moves to the leftmost side of the sliding groove, release your hand. Under the action of the rebound of the springs, the spring will push the lower pressure plate to move downward. Then, the two lower pressure plates will push the two limit blocks and the lower mold to move downward respectively, until one end of the two limit blocks is inserted into the two limit grooves on the leftmost side. Multiple lower molds can be added in sequence through the above operation.

[0011] Subsequently, when performing press bending, the staff places the sheet on the lower mold, and then starts the two hydraulic cylinders so that the output shafts of the two hydraulic cylinders drive the upper mold to move downward. Subsequently, the upper mold will contact the sheet and press and bend it. During the pressing and bending process, the rust on the sheet will fall off, and then the rust on the sheet will leak out from the through groove on the lower mold, and then the rust will pass through the discharge chute into the collection box for collection, ensuring that the rust on the sheet can be collected to avoid rust accumulation on the lower mold. No personnel are required to clean it, which is more convenient.

[0012] In the above technical solution, further, the collection box is plugged into and matched with the placement slot.

[0013] In this technical solution, it is ensured that the collection box can be drawn out from the placement slot.

[0014] In the above technical solution, further, the lower mold is slidably connected to the sliding groove, and the limit block is slidably connected to the sliding groove.

[0015] In this technical solution, it is ensured that the lower mold can slide in the sliding groove; it is ensured that the limit block can slide in the sliding groove

[0016] In the above technical solution, further, one end of the limit block is plugged into the limit groove, the other end of the limit block is in an inclined structure, and the limit block and the lower mold are an integrally formed structure.

[0017] In this technical solution, it is ensured that one end of the limit block can be inserted into the limit groove; the other end of the limit block is in an inclined structure, and when the other end of the limit block contacts and moves with the lower pressure plate, it can squeeze the lower pressure plate to move upward; the structural stability between the limit block and the lower mold is ensured.

[0018] In the above technical solution, further, the output shaft of the hydraulic cylinder is slidably connected to the L-shaped plate.

[0019] In this technical solution, it is ensured that the hydraulic cylinder can operate normally.

[0020] In the above technical solution, further, the plurality of limit grooves are linearly distributed with equal spacing.

[0021] In this technical solution, it is ensured that a plurality of lower molds can be fixed so that the plurality of lower molds can be arranged neatly.

[0022] The beneficial effects of the utility model are:

[0023] 1. The sheet metal bending machine, through the cooperation between the lower die, through the slot, discharge slot, placement slot and collection box, the rust falling on the sheet metal will leak out from the through slot on the lower die, and then the rust will pass through the discharge slot into the collection box for collection, ensuring that the rust on the sheet metal can be collected to avoid rust accumulation on the lower die, without the need for personnel to clean up, which is more convenient.

[0024] 2. The sheet metal bending machine, through the cooperation between the set sliding groove, the lower pressure plate, the spring, the limit groove and the limit block, does not need to use the motor and the screw rod. It is more convenient to install the lower mold, and there is no safety hazard and no personal injury. BRIEF DESCRIPTION OF THE DRAWINGS
