Description

Technical Field

[0001] This utility model relates to the field of steel structure processing and manufacturing technology, and more specifically, it relates to a bending fixture. Background Technology

[0002] Sheet bending is a common process in the metal processing field, and is widely used in industries such as automobile manufacturing, home appliance production, and building decoration. Traditional sheet bending fixtures mostly use methods such as die bending, hydraulic bending, or roll forming, which use external force to cause plastic deformation of the sheet to achieve the target bending angle or curvature.

[0003] However, while traditional sheet metal bending fixtures can meet the needs of mass production, they suffer from problems such as high equipment costs, large floor space, and complex operation. In particular, they are not flexible enough, have high energy consumption, and high maintenance costs for processing small and thin sheets, making them unsuitable for small-batch, multi-variety processing scenarios.

[0004] Therefore, a bending fixture is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a bending fixture to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A bending fixture includes a base with a positioning groove for inserting a sheet metal. Both sides of the base are fixedly connected to baffles, and both sides of the base are rotatably connected to drive arms. The drive arms are located on the side of the baffles away from the base. The baffles and the drive arms are respectively provided with a through-hole limiting groove one and a limiting groove two. The base is provided with a rolling roller that abuts against its surface, and the rotating shaft of the rolling roller is simultaneously located within the limiting groove one and the limiting groove two.

[0008] The technical solution of this utility model is further configured such that the limiting groove is parallel to the surface of the base.

[0009] The technical solution of this utility model is further configured as follows: a receiving groove is formed on the surface of the base, a mold base is detachably connected in the receiving groove, and the positioning groove is formed by the distance between the mold base and the inner wall of the receiving groove.

[0010] The technical solution of this utility model is further configured such that: a plurality of abutting members are detachably connected to the side of the baffle facing the base, and the abutting members are arranged in an array along the length direction of the positioning groove.

[0011] The technical solution of this utility model is further configured such that: a plurality of ejector components are detachably connected to the mold base, and the top end of the ejector component extends out from the mold base.

[0012] The technical solution of this utility model is further configured such that: both the clamping member and the ejecting member include a threaded connection part, a spring and a contact part, the contact part extends out from the threaded connection part, one end of the spring is fixedly connected to the threaded connection part, and the other end of the spring is fixedly connected to the contact part.

[0013] The technical solution of this utility model is further configured such that: the two drive arms are connected by a connector, and a control handle is fixedly connected to the connector.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] By creating limiting groove one and limiting groove two on the baffle and drive arm respectively, the drive arm can drive the rolling roller to move along limiting groove one when it rotates, thereby bending the sheet material with its bottom end located in the positioning groove along the surface of the mold base. This achieves the processing of small and thin sheet materials. Moreover, this method is simple to operate and highly flexible. The mold base can be disassembled and replaced according to actual needs to meet the needs of mass production.

[0016] The clamping parts on the baffle plate restrict the plate material located in the positioning groove, thereby ensuring its stability during processing and preventing displacement. The ejector parts on the mold base can lift the plate material after bending, making it easy for operators to remove the processed plate material. Furthermore, the ejector parts can retract into the mold base during the bending process, without affecting the bending effect. Attached Figure Description

[0022] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Example

[0023] refer to Figures 1 to 3 As shown, this utility model provides a bending fixture, including a base 1, a positioning groove 2 for inserting a sheet metal, baffles 3 fixedly connected to both sides of the base 1, and drive arms 4 rotatably connected to both sides of the base 1. The drive arms 4 are located on the side of the baffles 3 away from the base 1. The baffles 3 and the drive arms 4 are respectively provided with a through-hole limiting groove 5 and a limiting groove 6. The limiting groove 5 is parallel to the surface of the base 1. A rolling roller 7 is provided on the base 1 and abuts against its surface. The rotating shaft of the rolling roller 7 is located in both the limiting groove 5 and the limiting groove 6.

[0024] refer to Figures 1 to 3 As shown, a receiving groove 8 is provided on the surface of the base 1. A mold base 9 is detachably connected to the receiving groove 8. The positioning groove 2 is formed by the distance between the mold base 9 and the inner wall of the receiving groove 8. Two drive arms 4 are connected by a connector 15. A control handle 16 is fixedly connected to the connector 15. With the above structure, the mold base 9 can be removed from the base 1 and replaced according to the actual needs, so that this bending fixture can meet the needs of more scenarios. The presence of the connector 15 restricts the rotation of the two drive arms 4, which can only rotate together in the same direction. This makes it convenient for the operator to control the two drive arms 4 at the same time through the control handle 16, so as to realize the operation of the rolling roller 7 to bend the sheet metal.

[0025] refer to Figures 2 to 4As shown, a plurality of abutment members 10 are detachably connected to the side of the baffle 3 facing the base 1. The abutment members 10 are arrayed along the length direction of the positioning groove 2. A plurality of ejector members 11 are detachably connected to the mold base 9. The top end of the ejector member 11 extends out of the mold base 9. Both the abutment member 10 and the ejector member 11 include a threaded connection part 12, a spring 13 and a contact part 14. The contact part 14 extends out of the threaded connection part 12. One end of the spring 13 is fixedly connected to the threaded connection part 12, and the other end of the spring 13 is fixedly connected to the contact part 14. With the above structure, after the plate to be bent enters the positioning groove 2, the contact part 14 on the abutment member 10 is pushed by the spring 13, thereby moving towards the plate and pressing the plate against the inner wall of the positioning groove 2. After the plate has completed the bending work, the contact part 14 on the ejector member 11 is pushed by the spring 13, giving the plate an upward push, thereby causing the plate to separate from the surface of the mold base 9, making it easy for the operator to remove the processed plate.

[0026] refer to Figures 1 to 4 As shown above, when small, thin sheets need to be bent in large quantities, the corresponding mold base 9 can be installed into the receiving groove 8 of the base 1 with screws. Then, the sheet is inserted into the positioning groove 2, and the clamping member 10 clamps it to achieve the limit. Then, the control handle 16 can be operated to make the drive arm 4 rotate, thereby driving the rolling roller 7 to move from top to bottom along the limiting groove 5, bending the part of the sheet that extends out of the positioning groove 2. After the sheet has completed the bending work, the ejector 11 lifts the sheet, and the operator can take it out and place the next sheet. The whole process is simple, fast, flexible and efficient.
