Description

Technical Field

[0001] The utility model belongs to the technical field of tooling and relates to a folding tooling. Background Art

[0002] When a product is produced and processed, one of the components is welded to another component, and a certain space needs to be left between the two components. This requires bending the edge of one of the components, such as a plate.

[0003] The existing bending method is that the operator uses a hammer to hit the edge of a component, such as a plate, to achieve the folding. However, this bending method has low production efficiency and is purely based on the operator's experience and feel, so the product quality is difficult to guarantee. Summary of the invention

[0004] The utility model aims to solve the above problems existing in the prior art and proposes a folding tool to improve the folding efficiency of the plate.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a folding tool, including a frame, on which at least one driver is fixedly connected, characterized in that a connector is fixedly connected to the output shaft of each driver, all the connectors are connected to a pressure strip, the bottom of the pressure strip has a bending portion with a long strip shape and a sharp cross-section, the frame is fixedly connected to a pressure seat, the pressure seat has a bending groove with a long strip shape and a sharp cross-section, the bending groove is located directly below the bending portion, and the driver can drive the bending portion to move into the bending groove.

[0006] When working, the position where the plate needs to be folded is placed on the pressure seat, the driver works, and the pressure strip is driven to move through the connecting head, so that the bending part contacts the plate, and the driver continues to work to apply force. The bending groove plays a role of avoidance, and the bending part presses the plate into the bending groove, so that the edge of the plate is bent by the bending part. The bending part and the bending groove are both sharp-angled, so that the edge of the plate can be bent better. This folding tool realizes automated operation through the driver, the pressure strip and the pressure seat, improves the folding efficiency of the plate, and improves the folding accuracy of the plate.

[0007] In the above-mentioned folding tool, the angle of the sharp corner of the bending portion is smaller than the angle of the sharp corner of the bending groove. After the plate is bent, part of the plate and the bending portion will enter the bending groove. This structure allows the bending groove to have a better accommodating space to prevent the problem of jamming.

[0008] In the above-mentioned folding tool, the bottom of the bending part is rounded in a sharp angle. This structure enables the bending part to bend the plate better without damaging the plate.

[0009] In the above-mentioned folding tool, the bottom of the bending groove in a pointed shape has a buffer groove recessed downward, and the buffer groove is arranged along the length direction of the bending groove. The setting of the buffer groove has a certain buffering and avoiding effect, which can prevent the sharp corners of the bent plate from being damaged.

[0010] In the above-mentioned hemming tool, the top of the connector has a first avoidance groove, the bottom has a second avoidance groove, the output shaft of the driver is partially embedded in the first avoidance groove, the output shaft of the driver is hinged to the connector via a first hinge shaft, the pressure strip is partially embedded in the second avoidance groove, and the pressure strip is hinged to the connector via a second hinge shaft. This structure allows the output shaft to be better connected to the pressure strip, thereby improving the firmness of the pressure strip connection.

[0011] In the above-mentioned folding tool, the output shaft of the driver is perpendicular to the first hinge shaft and the second hinge shaft, and the central axis of the output shaft of the driver, the central axis of the first hinge shaft and the central axis of the second hinge shaft are located on the same plane. This structure allows the force of the driver to be better transmitted to the pressure strip, so that the bending part can better bend the plate.

[0012] In the above-mentioned folding tool, the pressure strip and the pressure seat are both in the shape of long strips, the pressure strip and the pressure seat have the same length, and the two ends of the pressure strip and the pressure seat are flush. This structure can improve the folding accuracy of the plate.

[0013] In the above-mentioned folding tool, there are two drivers, and the output shafts of the two drivers are respectively connected to the pressure strips, and the distance between the pressure strips and the two output shafts is slightly greater than the sum of the distances between the pressure strips and the two output shafts. This structure makes the pressure strips more uniform at all locations, so that the pressure strips can better bend the sheet.

[0014] In the above-mentioned folding tool, the frame includes a table plate, the pressure seat is in the shape of an elongated strip, and the pressure seat protrudes and is fixedly connected to the table plate.

[0015] In the above-mentioned folding tool, the driver is a pneumatic cylinder or an oil cylinder.

[0016] Compared with the prior art, the folding tool provided by the utility model has the following advantages:

[0017] 1. This folding tool realizes automatic operation through the driver, pressure strip and pressure seat, improves the folding efficiency of the plate, and improves the folding accuracy of the plate.

[0018] 2. The folding tool pushes the plate through the bending part so that the plate is partially embedded in the bending groove, thereby realizing the folding of the plate and making the bending of the plate convenient. BRIEF DESCRIPTION OF THE DRAWINGS
