In the modern steel door manufacturing industry, the roller rolling line production program occupies an extremely critical position. The program mainly focuses on all kinds of steel door frame molding processing, has excellent applicability. Whether it is civil security doors, building fire doors, or medical and electronic industry used in the purification of the door, it can easily cope with the complexity of the product size, fully meet the diversified production needs.

Compared with other production solutions, door frame molding line production solutions have obvious advantages. Compared with the traditional manual or single-machine processing solutions, the highly standardized workflow of the assembly line greatly reduces the dependence on the skills of workers, effectively avoiding the human factor caused by product defects, reducing scrap and rework. Compared with part of the semi-automated program, it is more coherent processes, the links closely cooperate, production efficiency is greatly improved.

From the working principle, the raw materials are loaded quickly and accurately by the automatic loading device, and then enter a series of professional mold stations in turn. During the transmission process, the door frame is gradually shaped by multiple sets of molds, and each step is monitored in real time by a high-precision inspection system to strictly control the dimensional accuracy. In order to meet the demand for different lengths, the assembly line is equipped with advanced length positioning devices. When the material reaches the specified position, the automatic cutter cuts off accurately, while the splicing port completes the synchronized molding. For special process requirements, such as door frame corner processing, hole stamping, etc., can be flexibly realized by adding professional equipment. The whole production process is smooth and efficient, which greatly reduces the defective rate and cuts down the production cost, showing a wide range of applicability and helping enterprises to complete the production of door frames with high efficiency and quality.

Recommended Requirements

Can be efficient and continuous operation, standardized operation, to ensure product quality;

Reduce labor costs

Standardized operation, effectively reduce the waste of raw materials

Standardized molds, the operating skills of workers do not require high;

Higher equipment procurement costs

Product molds and processes are fixed, such as changing products, mold replacement cycle is longer;

Door frame frame type is fixed, and the daily output demand ≥ 300;

can give full play to the advantages of automated assembly line of high efficiency and stability, to achieve large-scale, low-cost production, and further enhance market competitiveness.

Door frame automatic assembly line

Equipment Overview

is used for one-time punching and extrusion molding of door frame, the leveling can be completed at the same time when the coil material is fed, and after feeding, all kinds of holes can be formed through the front hydraulic press, after punching, the door frame can be formed through extrusion, and the rear hydraulic press can be selected to realize the molding of the holes that need to be punched, and the cut-off can be equipped with a straight cutter/circular saw with a flat cut of 90°, and a step cutter can be equipped with a step knife to complete the chopping and molding of the splicing port (most structures can be realized, and special structures may need a second chopping offline), and a combination of multiple knives can be selected as required. At the same time of cutting off, it can also be equipped with step knife to complete the chopping angle molding of the splicing mouth at one time (most of the structure can be realized, the special structure may need the second chopping angle under the line), and it can also be combined with multiple knives, according to the needs of the selection, and it can complete the chopping angle of a variety of splicing mouths in one machine, but it can't be chopped at 45 °, and it is necessary to individually configure the circular sawing machine or the hydraulic punching and shearing machine;
