Description

Technical Field

[0001] The utility model relates to the field of copper and aluminum bar processing, in particular to an assembly and bending jig. Background Art

[0002] Copper and aluminum busbars are a type of conductive material with a bright, round, and defect-free surface. They are suitable for electrical engineering projects such as high and low voltage electrical appliances, switch contacts, distribution equipment, and bus ducts. They are also widely used in ultra-high current electrolytic smelting projects such as metal smelting, electrochemical plating, and chemical caustic soda.

[0003] Currently, most copper and aluminum bars are bent using CNC machines. A copper and aluminum bar fixture and a bending jig with mechanical tension work together to quickly bend the bar. For example, for a 90° horizontal bend of a copper and aluminum bar, the bar to be bent is clamped into the fixture, and the end cap presses it. The rotating bending wheel on the side of the fixture then rotates, squeezing the bar and bending it at a certain angle.

[0004] When the bending wheel rotates and extrude the copper-aluminum bar, it needs to extrude from the other side of the bent side. Therefore, the clamp of the copper-aluminum bar not only fixes the copper-aluminum bar, but also acts as a bending support point. The bending wheel will exert a large force to prevent the bending wheel from damaging the surface of the copper-aluminum bar. Therefore, the bending wheel is usually made of non-metallic material and has a certain toughness, which can reduce the damage to the surface of the copper-aluminum bar caused by the bending wheel. However, the clamp of the copper-aluminum bar is usually a metal clamp, and the side of the copper-aluminum bar is usually semi-arc-shaped. This makes the clamp work as a bending support point, which will cause certain indentation wear on the inner side of the copper-aluminum bar bend. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide an assembly bending jig to solve the technical problems mentioned in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an assembly bending jig, comprising a chassis, a column installed on the top of the chassis, a chassis provided on the top of the column, and a clamping block movably installed on the top of the chassis, the outer part of the column is rotatably connected to a turntable, and the turntable is connected to a drive assembly, and a bending assembly is installed on the top of the turntable.

[0007] By adopting the above technical solution, a concave arc bending groove is set on the inner side of the clamping block, and the bending grooves on both sides of the copper-aluminum bar raw material are equal. Then, when the copper-aluminum bar is bent, the side of the copper-aluminum bar is engaged into the bending groove, so that the side of the copper-aluminum bar fits into the bending groove as a whole, thereby increasing the force-bearing area of the side of the copper-aluminum bar and reducing the local pressure on the side of the copper-aluminum bar, thereby achieving the effect of seamless bending.

[0008] The present invention is further configured such that two groups of clamping blocks are symmetrically arranged, and bending grooves are provided on the inner sides of the two groups of clamping blocks, and the curvature of the bending grooves matches the curvature of the side surfaces of the copper-aluminum bar.

[0009] By adopting the above technical solution, the copper-aluminum busbar can be better fixed by setting two sets of clamping blocks, and the requirement of bending the copper-aluminum busbar to both sides can be met.

[0010] The utility model is further configured such that the bending assembly is provided with a mounting bottom and a bending wheel, and the bending wheel is made of a non-metallic material and has good toughness.

[0011] By adopting the above technical solution, a bending assembly is provided to extrude the copper-aluminum bar so that the copper-aluminum bar is bent, and the bending wheel is made of non-metallic material with good toughness, which can reduce the indentation of the copper-aluminum bar.

[0012] The utility model is further configured such that two groups of tilt limit blocks are symmetrically arranged on the top of the chassis, a guide groove matching the tilt limit blocks is provided inside the clamping block, and a spring is provided between the clamping block and the chassis.

[0013] By adopting the above technical solution and providing two sets of tilting limit blocks and springs, the two sets of clamping blocks can slide on the tilting limit blocks, thereby realizing the separation and closing of the two sets of clamping blocks.

[0014] The utility model is further configured such that end covers are provided above the two groups of clamping blocks, and the tops of the end covers are connected to telescopic components.

[0015] By adopting the above technical solution, the clamping blocks can be compressed by setting the end covers, and while limiting the copper and aluminum bars from above, the two groups of clamping blocks can also be pushed to close and separate.

[0016] The utility model is further configured such that two groups of square grooves are opened on the top of the end cover, and the square grooves match the tilt limit blocks, so that the square grooves can avoid interference between the end cover and the tilt limit blocks.

[0017] By adopting the above technical solution and providing two sets of square grooves at the bottom of the end cover, the end cover and the tilt limit block are prevented from interfering with each other in movement when the end cover is pressed down.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The utility model sets a concave arc bending groove on the inner side of the clamping block, and the bending grooves on both sides of the copper-aluminum bar raw material are equal. Then, when the copper-aluminum bar is bent, the side of the copper-aluminum bar is engaged with the bending groove, so that the side of the copper-aluminum bar fits the bending groove as a whole, thereby increasing the force-bearing area of the side of the copper-aluminum bar and reducing the local pressure on the side of the copper-aluminum bar, thereby achieving the effect of seamless bending.

[0020] 2. The utility model is conducive to the rapid loading and unloading of copper and aluminum bars by arranging springs and inclined limit blocks between the chassis and the clamping blocks. Due to the arrangement of the bending grooves, the two sets of clamping blocks are tightly fitted with the copper and aluminum bars when closed. Therefore, when the clamping blocks are in the closed state, the copper and aluminum bars cannot be removed. The springs and inclined limit blocks can push the clamping blocks to separate a short distance, so that the copper and aluminum bars can be removed smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] The following describes an embodiment of the present invention based on its overall structure.

[0029] Example 1

[0030] An assembly bending jig, such as Figure 1-5As shown, it includes a chassis 1, a column 2 is installed on the top of the chassis 1, and a chassis 3 is provided on the top of the column 2, and a clamping block 4 is movably installed on the top of the chassis 3, the outer rotatable connection of the column 2 is connected to a turntable 7, and the turntable 7 is connected to a driving component, and a bending component 8 is installed on the top of the turntable 7. By providing a concave arc bending groove 6 on the inner side of the clamping block 4, the bending grooves 6 on both sides of the copper-aluminum bar raw material are equal, and then when the copper-aluminum bar is bent, the side of the copper-aluminum bar is engaged into the bending groove 6, so that the side of the copper-aluminum bar is fitted into the bending groove 6 as a whole, thereby increasing the force area of the side of the copper-aluminum bar and reducing the local pressure on the side of the copper-aluminum bar, thereby achieving the effect of seamless bending.

[0031] See also Figure 4 There are two groups of clamping blocks 4 symmetrically arranged, and the inner sides of the two groups of clamping blocks 4 are provided with bending grooves 6. The curvature of the bending grooves 6 matches the curvature of the side of the copper-aluminum bar. By setting two groups of clamping blocks 4, the copper-aluminum bar can be better fixed, and the requirements of bending the copper-aluminum bar to both sides can be met.

[0032] See also Figure 5 The bending component 8 is provided with an installation bottom and a bending wheel. The bending wheel is made of non-metallic material and has good toughness. By setting the bending component 8, it can be used to extrude the copper-aluminum bar so that the copper-aluminum bar is bent. The bending wheel is made of non-metallic material and has good toughness, which can reduce the indentation of the copper-aluminum bar.

[0033] Example 2

[0034] An assembly bending jig, such as Figure 1-5 As shown, two groups of tilting limit blocks 5 are symmetrically arranged on the top of the chassis 3, and a guide groove matching the tilting limit block 5 is provided inside the clamping block 4, and a spring is provided between the clamping block 4 and the chassis 3. By arranging the spring and the tilting limit block 5 between the chassis 3 and the clamping block 4, it is beneficial to the rapid loading and unloading of the copper and aluminum bars. Because of the setting of the bending groove 6, the two groups of clamping blocks 4 are tightly fitted with the copper and aluminum bars when closed. Therefore, when the clamping block 4 is in the closed state, the copper and aluminum bars cannot be removed, and the spring and the tilting limit block 5 can push the clamping block 4 to separate a short distance, so that the copper and aluminum bars can be smoothly removed.

[0035] See also Figure 1 An end cover 9 is provided above the two groups of clamping blocks 4, and a telescopic component is connected to the top of the end cover 9. By providing the end cover 9, the clamping block 4 can be pressed, and while limiting the copper and aluminum bars from above, the two groups of clamping blocks 4 can also be pushed to close and separate.

[0036] See also Figure 2Two groups of square grooves 10 are provided on the top of the end cover 9, and the square grooves 10 match the tilt limit block 5. The square grooves 10 can avoid interference between the end cover 9 and the tilt limit block 5. By providing two groups of square grooves 10 at the bottom of the end cover 9, the end cover 9 can avoid movement interference between the end cover 9 and the tilt limit block 5 when it is pressed down.

[0037] The working principle of the utility model is as follows: the telescopic assembly on the top of the end cover 9 contracts, driving the end cover 9 to rise, and then the two groups of clamping blocks 4 move obliquely upward along the inclined limit block 5 under the push of the bottom spring, so that the two groups of clamping blocks 4 are separated. At this time, the copper and aluminum bars are pushed between the two groups of clamping blocks 4 by conveying equipment or manually.

[0038] Next, the telescopic assembly on the top of the end cover 9 extends, pushing the end cover 9 to re-tighten the two sets of clamping blocks 4, and then the two sets of clamping blocks 4 begin to reset, and the excess tilt limit blocks 5 will extend into the square groove 10 to avoid interference between the square groove 10 and the tilt limit blocks 5.

[0039] At this time, the bending grooves 6 on the inner sides of the two sets of clamping blocks 4 are tightly fitted with the copper-aluminum bars. The driving assembly inside the chassis 1 is started to drive the turntable 7 to rotate, thereby driving the bending assembly 8 to rotate. The bending assembly 8 squeezes the copper-aluminum bar from one side of the copper-aluminum bar, pushing the copper-aluminum bar to bend to one side until it bends to a specified angle. The bending assembly 8 is a non-metallic material with a certain toughness, so the bending groove 6 and the bending assembly 8 can reduce the indentations on both sides of the copper-aluminum bar.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
