Description

Aluminum rod bending device

Technical Field

The invention relates to the field of machining, in particular to an aluminum rod bending device.

Background Art

Aluminum has been widely used in many fields due to its light weight. Such as support frames for small household appliances, household hangers, shelves and other equipment parts. Since aluminum bars are in a straight state after production, they need to be bent into a suitable size before use in specific products. Traditionally, when bending aluminum bars, fully automatic bending machines are often used to achieve this, but the cost of fully automatic bending machines is high and is not suitable for small enterprises to achieve small-batch production. At the same time, when some products use bent aluminum bars, the ends of the aluminum bars need to be processed into a flat shape first, and the bending direction and the flattening direction of the flat part have certain relative position requirements. Due to the limited functions of traditional automatic bending machines, operator assistance is required to ensure the above relative position requirements, which increases the workload of workers and cannot automatically achieve automatic bending operations, all of which have certain limitations. Therefore, a method or device that can solve the above problems is now needed.

DETAILED DESCRIPTION

The specific implementation of the present invention will be described below with reference to the accompanying drawings. As shown in Figures 1 to 5: an aluminum bar bending device, comprising a bottom plate 1, two pairs of symmetrically distributed support columns 2 are arranged on the top surface of the bottom plate 1, the top ends of the support columns 2 are commonly connected to a top plate 3, a first-stage cylinder 4 is arranged on the top plate 3, the working end of the first-stage cylinder 4 is connected to a floating plate 5, and the floating plate 5 is slidably connected to all the support columns 2, and two sets of symmetrically distributed upper bending mechanisms are arranged on the bottom end surface of the floating plate 5.

The upper bending mechanism comprises an upper mold 6 and a bending cylinder 7. A pressure block 8 is connected to the working end of the bending cylinder 7, and a roller 9 is rotatably supported on the pressure block 8.

The bottom plate 1 is provided with a first lower mold 10 and a second lower mold 11 corresponding to the two upper molds 6, respectively. A linear cylinder 12 is also provided on the bottom plate 1. A support plate 13 is provided on the slide of the linear cylinder 12. A finger cylinder 14 is provided on the top of the support plate 13. A movable limit block 15 is also provided on the slide of the linear cylinder 12. The movable limit block 15 corresponds to the fixed limit block 16 provided on the first lower mold 10.

The second lower mold 11 includes a lower block 17 and an upper block 18 which are slidably connected to each other. A lower driving plate 19 is arranged on the side wall of the upper block 18, and a lower inclined surface 20 is arranged on the lower driving plate 19. An upper driving plate 21 is arranged on the side wall of the upper mold 6 corresponding to the second lower mold 11, and an upper inclined surface 22 matching the lower inclined surface 20 is arranged at the bottom of the upper driving plate 21. At the same time, an upper connecting block 23 is also connected to the side wall of the upper block 18, and the bottom of the upper connecting block 23 is connected to one end of a spring 24, and the other end of the spring 24 is connected to a lower connecting block 25 fixedly arranged on the side wall of the lower block 17.

The working process of the aluminum bar bending device of the embodiment of the present invention is as follows: when it is necessary to bend the aluminum bar 26 whose end has been flattened, the operator first places the aluminum bar 26 on two lower jigs, that is, the aluminum bar 26 is supported by the first lower jig 10 and the second lower jig 11. When placing the aluminum bar, the flattened part of its end needs to be kept roughly vertical. Then the operator presses the button, and the control system controls the linear cylinder 12 to work, and drives the support plate 13 and the finger cylinder 14 thereon to move to the end of the aluminum bar 26 through the slide. When the moving limit block 15 contacts the fixed limit block 16, it indicates that the finger cylinder 14 has moved into place. Then the finger cylinder 14 works to clamp the flattened part of the aluminum bar 26, so that the aluminum bar 26 is adjusted to a processing posture for the bending operation. After the finger cylinder 14 works, it is released, and the slide on the linear cylinder 12 returns to its initial position.

After that, the control system will control the first-stage cylinder 4 to work, and the first-stage cylinder 4 drives the floating plate 5 downward. When the first-stage cylinder 4 moves to its limit stroke, the upper mold 6 connected to the bottom of the floating plate 5 will press on the corresponding lower mold, that is, the upper mold 6 and the lower mold jointly press and fix the aluminum rod 26. After the first-stage cylinder 4 finishes working, the control system controls the two bending cylinders 7 to work simultaneously, and the pressure block 8 moves downward, and the roller 9 thereon directly contacts the aluminum rod 26 and bends it, and the straight aluminum rod 26 will be bent into a concave shape. During the bending process, the roller 9 and the aluminum rod 26 roll relative to each other, thereby ensuring that the pressure applied to the aluminum rod 26 is uniform, and the friction between the two is rolling friction, which can effectively reduce the scratches on the surface of the aluminum rod 26 during the bending process and ensure the quality of the product; after the bending operation is completed, the bending cylinder 7 is recovered, the first-stage cylinder 4 is recovered, and the upper mold 6 returns to the initial position;

When the upper jig 6 approaches the lower jig, the upper driving plate 21 arranged on the upper jig 6 corresponding to the second lower jig 11 moves downward, and the upper inclined surface 22 at the bottom thereof contacts the lower inclined surface 20 arranged on the lower driving plate 19, so that the longitudinal linear motion between the upper jig 6 and the lower jig is converted into horizontal linear motion under the action of the inclined surface, driving the upper block 18 to move horizontally relative to the lower block 17, and this motion causes the spacing between the upper block 18 in the second lower jig 11 and the first lower jig 10 to increase, and the aluminum rod 26 can also achieve bending operation at this spacing;

After the upper jig 6 moves upward, the upper block 18 returns to its initial position under the action of the spring 24, that is, the distance between the upper block 18 and the first lower jig 10 returns to the initial distance. Then, the vertical part of the bent aluminum rod 26 will form a certain gap with the two lower jigs to prevent the bent aluminum rod 26 from being clamped on the two lower jigs, so that the operator can smoothly remove the bent aluminum rod 26 from the lower jig.
