Description

Technical Field

[0001] The utility model relates to the technical field of sculpture processing, in particular to a side bending mechanism for metal sculptures. Background Art

[0002] A sculpture refers to an ornamental object and a memorial object that is carved and shaped to beautify a city or for commemorative purposes, with certain implications, symbols or pictograms. Statues are widely used in squares, parks, etc. Most existing sculptures are processed by welding a metal shell on an internal skeleton.

[0003] When processing the metal shell, it is necessary to perform a bending operation on the side of the metal shell to prevent injury to people. Traditional bending methods are all completed by a bending machine, and it is necessary to manually stand up the metal shell and bend it by the bending machine, resulting in a large labor intensity. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above problems, and provide a side bending mechanism for metal sculptures, which can bend the side of the metal shell without standing up the metal shell, thereby reducing the labor intensity.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A side bending mechanism for metal sculptures includes an upper die and a lower die. An elevating plate that ascends and descends within the upper die is provided inside the upper die. A pressing head is provided at the lower end of the elevating plate. A positioning head that is inclined and inclinedly ascends and descends within the upper die is provided inside the upper die. A positioning groove that cooperates with the pressing head is provided at the lower end of the positioning head.

[0007] Further, a support plate is provided at the upper end of the elevating plate. A guide rod that passes through the support plate and is slidably connected to the support plate is provided at the upper end of the upper die. A first compression spring is provided on the guide rod.

[0008] Further, a guide groove that is inclined is provided inside the upper die. The guide groove is inclined outward from top to bottom, and the positioning head is arranged in the guide groove.

[0009] Further, a first groove is provided at the upper end of the guide groove. A second compression spring is provided in the first groove.

[0010] Further, a limiting groove is provided outside the upper end of the guide groove. A limiting head that moves within the limiting groove is provided on the outside of the positioning head.

[0011] Further, a second groove is provided at the left end of the lower die.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model includes an upper die and a lower die. An elevating plate that elevates within the upper die is provided inside the upper die. A pressing head is provided at the lower end of the elevating plate. A positioning head that is inclined and inclinedly elevates within the upper die is provided inside the upper die. A positioning groove that cooperates with the pressing head is provided at the lower end of the positioning head. When bending, one side of the metal shell is placed on the lower die. The upper die descends. The lower end of the positioning head first contacts the metal shell and retracts into the upper die under force. At the same time, the positioning head moves towards the side of the metal shell. Then the elevating plate descends, and the positioning head at the lower end of the elevating plate cooperates with the positioning groove to squeeze the side plate position of the metal shell, achieving bending and forming. The metal shell is placed flat on the lower die without the need to stand up, with low labor intensity and convenient positioning.

[0014] 2. A guiding groove that is inclined is provided inside the upper die. The guiding groove is inclined outward from top to bottom. The positioning head is arranged inside the guiding groove. When the upper die descends, the positioning head will move inward a small distance to squeeze the side plate of the metal shell. When the upper die ascends, the positioning head will move outward a small distance, and the lower end of the positioning head will separate from the side plate of the metal shell. When the upper die ascends, the lower end of the positioning head will not interfere with the bending position, that is, the upper die will not lift the metal shell when ascending.
