Description

Technical Field

[0001] The invention relates to the technical field of thin plate bending production, and in particular to an adjustable thin plate short side bending tool. Background Art

[0002] The heat shield is a key component for heat insulation in the brake system. It is used to prevent the brake pads from generating high temperatures during braking and damaging other components in the brake system. It is generally made of thin plates. During its production process, the edges of the thin plates need to be bent at a certain angle. The bending efficiency and quality directly affect the subsequent usability and safety.

[0003] Traditionally, the short side bending of the heat insulation screen mostly relies on manual operation. The short side bending position of the heat insulation screen is clamped with a vise or other tools, and the short side is bent manually with a hammer. This method cannot ensure the uniformity of the hammer force, which leads to cracks, surface scratches and inconsistent dimensions at the bend. It requires high experience from the operator and is labor-intensive. Summary of the invention

[0004] In order to solve the problems mentioned in the above background technology, the present invention provides an adjustable thin plate short edge bending tool to solve the problem of low product qualification rate caused by manual bending of the short edges of the heat insulation screen thin plates in the prior art.

[0005] The present invention discloses the following technical scheme: an adjustable thin plate short edge bending tool, comprising a punch and a base, wherein the bottom of the punch is a V-shaped angle structure with a mounting hole on the top, the base is provided with a V-shaped groove corresponding to the punch, and the base is provided with a T-shaped groove in a direction perpendicular to the V-shaped groove, and a screw, a gasket and a nut are installed in the T-shaped groove.

[0006] Furthermore, the bottom of the V-shaped angle at the bottom of the punch is a rounded angle of R0.3 to R0.5, and the root of the V-shaped groove of the base is a rounded angle of R0.3 to R0.5.

[0007] Furthermore, the angle between the bottom of the V-shaped angle on the punch and the root of the V-shaped groove on the base is 30 to 50 degrees.

[0008] Furthermore, the inclined surface of the V-shaped angle at the bottom of the punch is provided with a horizontal groove.

[0009] Furthermore, there are two T-shaped slots on the base, and scales are provided on the T-shaped slots.

[0010] Beneficial effects: Compared with the prior art, the adjustable thin plate short edge bending tool of the present invention can realize the bending of the short edges of thin plate parts by punching equipment, and is a multifunctional tool that can be adjusted according to the size of the heat insulation screen and the size of the bent short edge, thereby reducing manual labor intensity, improving production efficiency, reducing the damage rate of the heat insulation screen, and ensuring the consistency, reliability and pass rate of product size. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the overall structure of the present invention; Figure 2 It is a front view of the punch of the present invention; Figure 3 It is a schematic diagram of the base structure of the present invention; In the figure: 1-punch, 2-base, 3-screw, 4-washer, 5-nut. DETAILED DESCRIPTION

[0012] like Figures 1 to 3 As shown, an adjustable thin plate short edge bending tool includes a punch 1 and a base 2. The bottom of the punch 1 is a V-shaped angle structure, which is used to bend the thin plate. A mounting hole is provided on the top to facilitate the installation of the punch 1 on the punch press. The base 2 is provided with a V-shaped groove corresponding to the punch 1, and cooperates with the punch 1 to bend the thin plate. A T-shaped groove is provided on the base 2 in a direction perpendicular to the V-shaped groove. A screw 3, a gasket 4 and a nut 5 are installed in the T-shaped groove, which is used to position the bent short edge of the thin plate to ensure the accuracy of the short edge size, and the position of the screw 3 can be adjusted according to short edges of different lengths.

[0013] The bottom of the V-shaped angle at the bottom of the punch 1 is a rounded angle of R0.3 to R0.5, and the root of the V-shaped groove of the base 2 is a rounded angle of R0.3 to R0.5, which prevents stress concentration from damaging the thin plate during bending; the angle between the bottom of the V-shaped angle on the punch 1 and the root of the V-shaped groove on the base 2 is 30 to 50 degrees, which is convenient for bending operations; the inclined surface of the V-shaped angle at the bottom of the punch 1 is provided with a horizontal groove, and when the short side of the thin plate is bent, the short side of the thin plate will rebound at a certain angle due to its toughness, and the edge of the short side will bend toward the groove to ensure the accuracy of the bending angle; there are two T-shaped grooves on the base 2, and scales are provided at the T-shaped grooves, which is convenient for quickly adjusting the position of the screw 3 according to the size of the short side of the thin plate to ensure the accuracy of the bending size.

[0014] When in use, the punch 1 is installed on the punch press, and the base 2 is installed on the workbench of the punch press, so that the V-shaped groove of the base 2 corresponds to the V-shaped angle position of the punch 1, and the position of the screw 3 is adjusted according to the short side size that needs to be bent, and the thin plate part is placed on the base 2 and abutted against the edge of the gasket 4, and the punch press is started. The punch 1 moves downward to bend the thin plate part. The tooling is easy to operate, the bending short side size is accurate, the product qualification rate is high, and the labor intensity is reduced.

[0015] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
