Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, and in particular to a bending machine for embedding strips in civil defense door frames. Background Technology

[0002] As we all know, the cladding strip of the air-raid shelter door frame is one of the main components of the door frame. The quality of the cladding strip directly affects the airtightness of the air-raid shelter door frame. Therefore, ensuring the quality of the cladding strip is particularly important in the production of the door frame. According to national standards, the airtightness of the air-raid shelter door should be guaranteed after the cladding strip of the air-raid shelter door frame is welded.

[0003] Currently, in the past production process of the cladding strips for civil defense door frames, operators need to cut flat steel into eight sections according to the dimensions, then punch the four corners into arcs on a punch press, and then weld the four straight edges together. However, the applicant found that the cladding strips for civil defense door frames produced in this way not only have many welding joints, but also need to be ground after welding, which leads to low production efficiency and affects the appearance quality.

[0004] Therefore, in response to the aforementioned technologies, we propose a bending machine for the embedding strips of civil defense door frames. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-4 In this embodiment of the utility model, a bending machine for embedding strips in a civil defense door frame includes:

[0028] Workbench 1;

[0029] Electro-hydraulic push cylinder 2 is detachably connected to the worktable 1 via mounting plate 3, and its output end is detachably connected to a bending part 4.

[0030] The limiting post 5 is detachably connected to the workbench 1 via the connecting plate 6, and its limiting post 5 corresponds to the bending part 4.

[0031] A positioning component is provided on the worktable 1 and is used to fix and limit the material to be bent on the worktable 1.

[0032] A support assembly is provided at the bottom of the worktable 1, which is used to support the worktable 1 in the position of use.

[0033] This mortise and tenon door frame embedding strip bending machine can be used by setting up a support component to support and place its worktable 1 in the working position. Then, the sheet material to be bent is placed on the worktable 1. At the same time, a positioning component can be set up to fix and limit the sheet material on the worktable 1. Then, by activating the electro-hydraulic push cylinder 2, the sheet material is bent through the cooperation of the electro-hydraulic push cylinder 2, the bending part 4 and the limiting column 5.

[0034] exist Figure 1-3The positioning component includes an electro-hydraulic actuator 7 and a connecting frame 8. The electro-hydraulic actuator 7 is detachably connected to the worktable 1 via a connecting plate. The output end of the electro-hydraulic actuator 7 is fixedly connected to a positioning seat 9. The connecting frame 8 is fixedly connected to the worktable 1 and corresponds to the electro-hydraulic actuator 7. One end of the connecting frame 8 is fixedly connected to a limit seat 10. Anti-slip pads 11 are provided on the opposite ends of the positioning seat 9 and the limit seat 10.

[0035] This door frame embedding strip bending machine, through this structure, after the sheet material to be bent is placed on the workbench 1, can be activated by starting the electro-hydraulic push rod 7. The operation of the electro-hydraulic push rod 7 will drive its positioning seat 9 to move, so that the positioning seat 9 and the limiting seat 10 are tightly attached to the outer surface of the sheet material, thereby achieving the purpose of fixing and limiting the sheet material.

[0036] exist Figure 1-4 The support assembly includes four support columns 12, which are all installed in the workbench 1 through connecting grooves. The other end of each support column 12 is fixedly connected to a support base 13. The cooperation between the support column 12 and the support base 13 facilitates the placement of the workbench 1 in the usage position. The bottom of each support base 13 is fixedly connected to an anti-slip pad 14. The anti-slip pad 14 increases the contact friction between the support base 13 and the ground, preventing slippage during use. The limiting column 5 is fixedly fitted with an anti-slip rubber sleeve 15 to prevent the material from slipping on the limiting column 5.

[0037] In this embodiment, the electro-hydraulic cylinder 2 and the electro-hydraulic actuator 7 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, so we will not go into detail here. Both the electro-hydraulic cylinder 2 and the electro-hydraulic actuator 7 are equipped with matching control switches. The installation position of the control switches is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0038] The implementation principle of the blast furnace door frame embedding strip bending machine according to this application embodiment is as follows: First, the workbench 1 is supported and placed in the use position by the mutual cooperation of multiple support columns 12 and support seats 13. Then, the sheet material to be bent is placed on the workbench 1. The user can start the electro-hydraulic push rod 7. With the mutual cooperation of the electro-hydraulic push rod 7 connecting frame 8, positioning seat 9 and limiting seat 10, the positioning seat 9 and limiting seat 10 are tightly attached to the outer surface of the sheet material, thereby achieving the purpose of fixing and limiting the sheet material. Then, the electro-hydraulic push cylinder 2 can be started. The operation of the electro-hydraulic push cylinder 2 will drive its bending part 4 to move. Then, with the mutual cooperation of the bending part 4 and the limiting column 5, the purpose of bending the sheet material can be achieved.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
