Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sheet metal processing and forming, and particularly relates to a local heating assisted forming device. Background Technique
[0002] Sheet metal forming technology is a very widely used process for processing metal or non-metal sheets into required shapes. Sheet metal forming is widely used in many industries, including automobile manufacturing, aerospace, household appliances and construction. There are three sheet metal forming methods, namely cold forming, hot forming and composite forming. Cold forming requires the use of bending machines, stretching machines, punching presses, etc., and also requires molds. Among them, the mold cost is relatively high, and a set of molds is required for each shape of a product, which greatly increases the production cycle of the product. Content of the Utility Model
[0003] In order to make up for the deficiencies of the prior art, the utility model provides a local heating assisted forming device that saves costs and has a short processing cycle.
[0004] The utility model is realized by the following technical solutions:
[0005] A local heating assisted forming device includes a seat body for placing a sheet. The feature is that: a pressing column is arranged above the seat body, the pressing column is installed at the bottom of a pressing seat, a pressing oil cylinder is connected above the pressing seat, a concave cavity is provided in the seat body, a sealing plate installed on the seat body is arranged at the lower part of the concave cavity, a nitrogen inlet penetrates through the sealing plate, a robotic arm is installed on the sealing plate, and a laser heat source is installed at the top of the robotic arm.
[0006] A pressing wheel is installed at the bottom of the pressing column.
[0007] An intake valve is arranged on the nitrogen inlet.
[0008] The beneficial effect of the utility model is that the sheet can be formed by using the laser heat source, and for different shape requirements, by setting different rotation radii of the laser heat source, the forming can be completed without the need for a mold, which greatly saves the production cost and reduces the processing cycle. Description of the Drawings
[0009] The following further describes the utility model with reference to the drawings.
[0010] Att Figure 1 is a schematic structural diagram of the utility model;
[0011] In the figure, 1 is the sheet, 2 is the seat body, 3 is the pressing column, 4 is the pressing seat, 5 is the pressing oil cylinder, 6 is the concave cavity, 7 is the sealing plate, 8 is the nitrogen inlet, 9 is the robotic arm, 10 is the laser heat source, 11 is the pressing wheel, and 12 is the intake valve. Detailed Embodiment
[0012] The accompanying drawings are a specific embodiment of the utility model. This embodiment includes a seat body 2 for placing a plate 1, a pressing column 3 is provided above the seat body 2, the pressing column 3 is installed at the bottom of a pressing seat 4, a pressing cylinder 5 is connected above the pressing seat 4, a concave cavity 6 is opened in the seat body 2, a sealing plate 7 installed on the seat body 2 is provided at the lower part of the concave cavity 6, a nitrogen inlet 8 is penetrated in the sealing plate 7, a mechanical arm 9 is installed on the sealing plate 7, and a laser heat source 10 is installed on the top of the mechanical arm 9. A pressing wheel 11 is installed at the bottom of the pressing column 3. An air inlet valve 12 is provided on the nitrogen inlet 8.
[0013] The local heating auxiliary forming device of the utility model is used to place the plate 1 above the concave cavity 6 of the seat body 2, and the pressing cylinder 5 is started. The pressing cylinder 5 drives the pressing seat 4 and the pressing column 3 to press tightly on the plate 1. According to the shape requirements of the required forming, the movement trajectory program of the robot 9 is set, the air inlet valve 12 is opened, and nitrogen with a pressure greater than one atmosphere is injected into the concave cavity 6. The robot 9 is started to drive the laser heat source 10 to rotate directly toward the plate 1, so that the heated part can be deformed and convex upward under the air pressure until the plate 1 reaches the desired conical shape. In the process of the plate 1 moving toward the center, the pressing wheel 11 reduces the friction while pressing, greatly reducing the damage to the plate.
