Embodiment 1

[0033] An automatic fastening device for the production of refrigerator liners, comprising a base 1, a first moving plate 5 is slidably connected to both sides of the top of the base 1, and a second moving plate is slidably connected to the tops of the two first moving plates 5 17. The tops of the two second moving plates 17 are fixedly connected with expansion boards 23 for binding the inner container of the refrigerator, and the top of the base 1 is fixedly connected with two U-shaped plates 24, and the sides of the two U-shaped plates 24 are close to each other. Both are provided with an extruding mechanism for fastening the inner container of the refrigerator, and the middle part of the top of the base 1 is fixedly connected with an inner formwork 29, and the two inner formworks 29 are located at the middle position between the two U-shaped plates 24. The interior of the inner formwork 29 is provided with a positioning mechanism for initially fixing the refrigerator inner c...

Embodiment 2

[0043] An automatic fastening device for the production of a freezer liner. On the basis of Embodiment 1, the extrusion mechanism includes two sets of oil cylinders 25, and the two sets of oil cylinders 25 are installed inside the corresponding U-shaped plate 24. The two sets of oil cylinders 25 The sides close to each other are equipped with cylinders 26, and the sides of the two sets of cylinders 26 close to each other are fixedly connected with buckling mold strips 27 that squeeze the inner liner of the refrigerator, and one side of the buckle mold strips 27 is provided with a notch 35.

[0044] In this embodiment, there are two sets of oil cylinders 25 in each of the two sets of oil cylinders 25 , and oil cylinder joints 36 are installed on one side of each set of oil cylinders 25 , and oil pipes 37 are communicated between each set of oil cylinder joints 36 .

[0045] Specifically, the oil cylinder joints 36 are connected through oil pipes 37, which is convenient for refu...

Embodiment 3

[0049] An automatic fastening device for the production of a freezer liner. On the basis of Embodiment 1, the positioning mechanism includes a T-shaped plate 33, and the inside of the inner template 29 is provided with a chute 30 and a T-shaped groove 32. The chute 30 and The T-shaped grooves 32 communicate with each other, the inner thread of the chute 30 is connected with a nut 31 , the inner sliding connection of the T-shaped groove 32 is connected with a T-shaped plate 33 , and a spring 34 is fixedly connected between the nut 31 and the T-shaped plate 33 .

[0050] Specifically, when the fastening positions of the large and small templates are located inside the notch 35, the T-shaped plate 33 fixes one side of the templates, preventing the large and small templates from sliding when they are engaged.

[0051] Working principle: Start the first driving device 8, drive the first screw 9 and the second screw 10 to rotate, thereby driving the first moving plate 5 to move, so t...

Abstract

The invention discloses an automatic buckling device for refrigerator inner production, relates to the field of refrigerator liner production, and aims to solve the problems that multiple workers and multiple processes are needed to assist in buckling of existing refrigerator liners, the efficiency is low, the number of workers is large, the product size is unstable, and a special blanking machine and a bending machine have the risk of mechanically hurting people. The following scheme is now put forwards. According to the technical scheme, the device comprises bases, the top ends of the bases are fixedly connected with two U-shaped plates, the sides, close to each other, of the two U-shaped plates are each provided with an extrusion mechanism used for buckling a refrigerator liner, and the middles of the top ends of the bases are fixedly connected with inner mold plates. Positioning mechanisms for preliminarily fixing the refrigerator liner when the refrigerator liner is placed on the device are arranged in the two inner mold plates. Buckling mold strips are driven by oil cylinders to firmly buckle a large coaming and a small coaming of the refrigerator liner, the whole buckling process only needs to be assisted by a single person beside, automatic buckling is achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of production of refrigerator liners, in particular to an automatic fastening device for the production of refrigerator liners. Background technique [0002] Freezer is another name for refrigerator and freezer. The freezer is composed of three parts: a shell, a refrigeration system, and a temperature control device. The shell is mainly composed of an outer box and an inner tank. The production process of the inner tank requires the inner tank The size of the hoarding boards are fastened together. [0003] In the prior art, the fastening of the refrigerator liner requires multiple workers and multiple processes to assist the fastening, which is inefficient, takes up a lot of personnel, the product size is unstable, and there is a risk of mechanical injury on the special punching machine and bending machine. Therefore, how to Efficiently and safely snapping together the large and small enclosures of the inner tank is ...
