Problems solved by technology

[0003] However, in the actual production and processing process, due to the thicker thickness of the cold-rolled steel door, in order to improve the thermal insulation performance, it is necessary to fill the thicker inner cavity with dense insulation Hot objects need to consume a large amount of heat-insulating filler, and at the same time increase the weight of the cold-rolled steel door, causing the cold-rolled steel door to bear a large load at the connection position, which is prone to deformation. At the same time, the existing cold-rolled steel door production filling device Lack of extruding device, so that the filler cannot be compactly pressed and filled in the inner cavity of the cold-rolled steel door, resulting in poor heat insulation effect
[0004] For this reason, a cold-rolled steel door with heat insulation and its production device are provided to solve the problem of overweight and dense filling of cold-rolled steel doors

Embodiment 1

[0052] Embodiment 1: For the filling production process of the cold-rolled steel door with a relatively short filling cavity 6, a single extrusion is used for compaction.

[0053] Through the cooperation of the clamping plate 18 and the fastener 19, the end of the cold-rolled steel door is clamped and fixed, and the convenient connection with the regulating air pump 20 is realized by setting the inner liner 10 with the connecting valve 9 , by adjusting the air pump 20 to drive the piston 28 in the lifting cavity 11, to drive the extruding rod 25 and the active rod 26 to slide back and forth, and by setting the slider 29 to cooperate with the chute 24, the sliding of the slide plate 22 is realized The positions are relative to ensure that the sliding plate 22 keeps sliding in parallel, so that the filling and pressing device 27 maintains a stable extrusion in the filling cavity 6, and the filling cavity 6 is filled with material by setting the filling port 4 and the feed pump 21...

Embodiment 2

[0054] Embodiment 2: When the filling length of the cold-rolled steel door is long, the filling port 4 is used to realize the filling and extrusion of multiple batches in sections. During the filling and driving process, the air intake is controlled by adjusting the air pump 20, so as to achieve the adjustment of driving and extrusion. The purpose of pressing the distance is to ensure the dense filling of the filler, thereby improving the filling quality and thermal insulation performance

Embodiment 3

[0055] Embodiment 3: Due to the deviation in the amount of the heat-insulating filler 7 entering once, there is also a deviation in the adjustment of the intake air volume of the air pump 20, which may easily cause the extrusion driving distance to be insufficient or too long. When the extrusion distance is insufficient, it cannot To achieve tight compaction, when the extrusion distance is too long, it is easy to cause the rod to break due to extrusion.

[0056] By setting the cooperation between the fixed plate 32 and the pressing plate 33 that can be extruded, in the error range where the extruding distance is insufficient or too long, the compression amount of the spring 30 is used for buffering, so that the clamping distance driven by the air pump 20 and the filling ratio can be adjusted. The width is adapted to achieve the purpose of improving the quality of filling compaction.

Abstract

The invention relates to the technical field of cold-rolled steel door production, in particular to a heat-insulation cold-rolled steel door and a production device.The heat-insulation cold-rolled steel door comprises a cold-rolled steel door body, the cold-rolled steel door body comprises a front plate, a rear plate and a heat-insulation composite frame, the heat-insulation composite frame is installed between the front plate and the rear plate in a sealed and clamped mode, and a pair of partition plates parallel to each other are vertically arranged in the heat-insulation composite frame; the thermal insulation composite frame has the advantages that the composite frame with the partition plate is arranged, so that a hollow inner cavity is formed in a filling inner cavity, the filling inner cavity is greatly reduced, the requirement for the filler is reduced, the weight is reduced, and the thermal insulation composite frame is convenient to mount and dismount. Meanwhile, two compactly-filled heat insulation filling layers are formed through fixing of the partition plate, the weight is reduced while the heat insulation quality is guaranteed, and the service life of the cold-rolled steel door is prolonged.

Description

technical field [0001] The invention relates to the technical field of cold-rolled steel door production, in particular to a heat-insulating cold-rolled steel door and a production device thereof. Background technique [0002] Cold-rolled steel doors are composite doors formed by cold-rolling. Because the thickness of cold-rolled steel doors is relatively thick, in order to improve their performance, cold-rolled steel doors are usually filled with insulation for the purpose of heat insulation. . [0003] However, in the actual production and processing process, due to the thicker thickness of the cold-rolled steel door, in order to improve the thermal insulation performance, it is necessary to fill the thicker inner cavity with dense thermal insulation, which consumes a large amount of thermal insulation filler and increases the temperature at the same time. The weight of the cold-rolled steel door is reduced, causing the cold-rolled steel door to bear a large load at the c...
