Description

Technical Field

[0001] This utility model relates to the field of metal door and window technology, specifically to a metal door and window processing bending device. Background Technology

[0002] Metal doors and windows refer to the collective term for ferrous and non-ferrous metal materials used in construction projects. These materials mainly include steel, cast iron, aluminum, and copper products. Metal doors and windows not only include traditional metal doors and windows, but also encompass other metal products such as metal gates, metal railings, metal fences, and railings.

[0003] Application number CN211588122U discloses a metal material bending processing device. The device places the metal material between the processing surfaces of a die and a punch, and a linear telescopic actuator drives the die towards the punch to bend the metal material. Because the punch is fixed in position, the die can only move along the die groove, solving the problems of slow efficiency, uncontrolled bending angle, and poor dimensional accuracy of the original manual method. This device can be used for bending metal doors and windows. However, the design still has shortcomings. The upper surface of the device lacks a limiting mechanism, causing the metal material to spring up during bending, potentially posing a safety hazard.

[0004] Therefore, we propose a bending device for metal door and window processing. Utility Model Content

[0005] The main purpose of this utility model is to provide a bending device for metal door and window processing. By using a limiting mechanism, it can prevent metal door and window workpieces located in the bending channel from being ejected from the upper surface of the mounting plate due to force, thereby improving its safety and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A metal door and window processing bending device includes a punch, a die, and a mounting plate. The punch and die are respectively mounted on one side of the mounting plate. The punch and die are arranged opposite to each other. A bending channel for placing metal door and window workpieces is provided between the punch and die. Limiting mechanisms for limiting the position of metal door and window workpieces are also installed at both ends of the mounting plate near the punch and die.

[0008] The limiting mechanism includes a base, a column, an assembly plate, a top plate, a lead screw, a fixing bolt, a limiting plate, a mounting sleeve, a protective pad, and a protrusion. The base, column, and mounting sleeve are each provided in two sets. The lower part of both sides of the base is vertically connected to the assembly plate, and the assembly plate is fixedly connected to the upper surface of the mounting plate by a first bolt.

[0009] By adopting the above technical solution, a limiting mechanism for limiting the position of metal door and window workpieces is installed at both ends of the mounting plate near the punch and die. The assembly plates at the lower part of both sides of the column are fixedly connected to the upper surface of the mounting plate by the first bolt. The mounting sleeve with the top plate is placed on the column. According to the size of the metal door and window workpiece, the height of the limiting plate can be adjusted. By turning the screw, the screw can push the limiting plate towards the metal door and window workpiece through the threaded engagement between the screw and the top plate, until the limiting plate is pushed to the designated position. It has the advantage of simple operation.

[0010] Specifically, the top plate is a horizontally arranged rectangular plate structure, and both ends of the top plate are fixedly engaged with the top of the mounting sleeve. A limit plate is also slidably connected between the two sets of mounting sleeves.

[0011] Specifically, one end of the lead screw passes through the top plate and is rotatably connected to one side of the limiting plate.

[0012] Specifically, the limiting plate has a protrusion on the side away from the lead screw, and a protective pad is fixedly glued to the side of the protrusion away from the limiting plate.

[0013] Specifically, the mounting sleeve is placed on the column, the top of the mounting sleeve is threaded with a fixing bolt, the bottom of the fixing bolt passes through the mounting sleeve and is threaded to the top of the column, and the top of the column is provided with a threaded hole that matches the fixing bolt.

[0014] Specifically, a limiting cavity is provided between the two sets of mounting sleeves, and a sliding groove is provided on the side of the mounting sleeve near the limiting cavity that is adapted to both ends of the limiting plate.

[0015] The beneficial effects of this utility model are:

[0016] (1) The metal door and window processing bending device of this utility model has a limiting mechanism for limiting the position of the metal door and window workpiece installed at both ends of the mounting plate near the punch and die. The assembly plates at the lower part of both sides of the column are fixedly connected to the upper end of the mounting plate by the first bolt. The mounting sleeve with the top plate is placed on the column. By using the limiting mechanism, the metal door and window workpiece located in the bending channel can be prevented from popping out from the upper end of the mounting plate due to force, thereby improving its safety.

[0017] (2) The metal door and window processing bending device of this utility model can adjust the height of the limiting plate according to the size of the metal door and window workpiece. By turning the screw, the screw can push the limiting plate towards the metal door and window workpiece through the threaded engagement between the screw and the top plate, until the limiting plate is pushed to the designated position. It has the advantage of simple operation. Attached Figure Description
