Description

Technical Field

[0001] The utility model relates to the technical field of bending moulds, in particular to a bending mould with a synchronous seesaw. Background Art

[0002] In the process of bending products, a punch is often used to press the bent product downward into a die to force the product to bend. However, since the shape of the product is large before the bend, the inertia is large during the bending process. After bending, the inertial resistance of the product's periphery causes the product to be severely deformed, resulting in serious product failures. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the utility model provides a bending mold with a synchronous seesaw. When the product starts to bend, the synchronous bending plate follows the periphery of the product and synchronously lifts it up in the direction required by the product. Due to the different hardness and softness of the product material, the rebound of the product during the bending process will vary greatly. By adjusting the adjustment block, the synchronous bending plate can advance or delay the product to compensate for the rebound.

[0004] To achieve the above-mentioned purpose, a bending mold with a synchronous seesaw includes a base, the base is connected to a bending die, a bending punch matching the bending die is provided above the bending die, an auxiliary bending structure is provided between the bending die and the bending punch, the auxiliary bending structure includes a fixed groove, a synchronous lifting bracket and a connecting plate, fixed grooves are respectively provided on the base surfaces on the left and right sides of the bending die, two synchronous lifting brackets are provided in the fixed grooves on the same side, the synchronous lifting brackets on the left and right sides are connected by a connecting plate, and one end of the synchronous lifting bracket is rotatably connected to the base through an intermediate shaft.

[0005] The synchronous lifting bracket and the connecting plate are an integrated structure.

[0006] A plurality of protrusions are arranged in the fixing groove, and grooves matching with the protrusions are arranged on the synchronous lifting bracket.

[0007] The connecting plate is connected to the bent product via fasteners.

[0008] The middle of the bending punch structure is a thick plate, and thin plates are connected to both sides of the thick plate.

[0009] The upper end of the bending punch is connected to the driving mechanism, and an adjusting block is arranged between the bending punch and the driving mechanism.

[0010] The regulating block is a rectangular cushion block with elasticity.

[0011] The inner wall of the base is provided with an axis groove for fixing the intermediate shaft, and a fixing plate is provided above the axis groove.

[0012] Compared with the prior art, the utility model has the advantage that the inertia of the product periphery is offset by the addition of a synchronous bending plate, and the product quality is guaranteed. The structure plays a role in guaranteeing the forming of similar products in the future. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The utility model is further described below with reference to the accompanying drawings.

[0025] like Figures 1 to 4As shown, the base 5 is connected to the bending die 2, and a bending punch 1 cooperating with the bending die 2 is provided above the bending die 2, and an auxiliary bending structure is provided between the bending die 2 and the bending punch 1, and the auxiliary bending structure includes a fixing groove 7, a synchronous lifting bracket 4.1 and a connecting plate 4.2. The surfaces of the base 5 on the left and right sides of the bending die 2 are respectively provided with fixing grooves 7, and two synchronous lifting brackets 4.1 are provided in the fixing grooves 7 on the same side. The synchronous lifting brackets 4.1 on the left and right sides are connected by a connecting plate 4.2, and one end of the synchronous lifting bracket 4.1 is rotatably connected to the base 5 through an intermediate shaft 10.

[0026] The synchronous lifting bracket 4.1 and the connecting plate 4.2 are an integrated structure.

[0027] A plurality of protrusions 8 are arranged in the fixing groove 7, and a groove 9 matching with the protrusions 8 is arranged on the synchronous lifting bracket 4.1. The protrusions 8 and the groove 9 are connected to limit the displacement of the synchronous lifting bracket 4.1.

[0028] The bending product 3 is connected to the connecting plate 4.2 by fasteners. In the present utility model, the fasteners are detachable bolts, which are used to fix during operation and are disassembled after the operation is completed.

[0029] like Figure 5 The structure of the bending punch 1 is divided into three parts, with a thick plate in the middle and thin plates connected on both sides of the thick plate.

[0030] The upper end of the bending punch 1 is connected to the driving mechanism, and an adjustment block 6 is provided between the bending punch 1 and the driving mechanism. By adjusting the padding or not of the adjustment block 6, the synchronous lifting bracket 4.1 can be lifted in advance or delayed to push the bent product 3 through the connecting plate 4.2 to solve the compensation rebound.

[0031] The adjusting block 6 is a rectangular cushion block with elasticity.

[0032] The inner wall of the base 5 is provided with an axis groove 12 for fixing the intermediate shaft 10, and a fixing plate 11 is provided above the axis groove 12. The fixing plate 11 serves to prevent the synchronously lifted bracket 4.1 from falling out.

[0033] During the actual operation of the utility model, the two synchronous lifting brackets 4.1 are first connected through the connecting plate 4.2, and the synchronous lifting bracket 4.1 is rotatably connected to the shaft groove 12 of the base 5 through the intermediate shaft 10. Finally, the fasteners are installed to fix the intermediate shaft 10, wherein the fasteners are detachable bolts. The staff starts the driving mechanism, and the driving mechanism makes the bending punch 1 press the bending product 3 and the synchronous lifting brackets 4.1 on the left and right sides into the bending die 2 respectively. When the bending product 3 starts to bend, the two ends of the synchronous lifting brackets 4.1 on both sides are tilted to support the connecting plate 4.2 to push the two ends of the bending product 3 to tilt synchronously. The connecting plate 4.2 offsets the inertia of the periphery of the bending product 3. At the same time, according to the hardness of the actual processing of the bending product 3, the pad or no pad adjustment block 6 is selected, so that the synchronous lifting bracket 4.1 is advanced or delayed to push the bending product 3 through the connecting plate 4.2 to solve the compensation rebound, so that the bending product 3 is not easily deformed due to the inertial resistance of the bending, so that the quality of the bending product 3 is guaranteed. After the operation is completed or the structure fails, the fasteners are removed.
