Description

Technical Field

[0001] This utility model relates to the field of strip forming technology, and more specifically, to a strip forming system. Background Technology

[0002] In the prior art, there is a door structure in which glass is embedded in the middle of the door. In order to install the glass on the door, a through hole for installing the glass must first be machined in the door (this through hole is usually a rectangular hole). Then, a pressure strip needs to be installed in this through hole, and then the glass is fixed in the through hole by the pressure strip.

[0003] The molding strips used to produce this type of door have a variety of cross-sectional structures, so a special production line is required to produce them.

[0004] However, some existing production lines for this type of pressing strip have the following problems: after the pressing strip is rolled into shape by the forming equipment, it is inconvenient to cut the pressing strip according to the actual situation, because some assemblies require the pressing strip to be completely cut off, while other assemblies cannot completely cut off the pressing strip.

[0005] Therefore, a strip forming system is proposed. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a strip forming system.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A strip forming system includes a feeding device. A roll forming machine, a punching die, and a corner cutting die are sequentially arranged at the outlet of the feeding device. The arrangement direction of the roll forming machine, the punching die, and the corner cutting die is the same as the feeding direction of the feeding device. The corner cutting die can cut or partially cut the formed and punched strip.

[0009] Furthermore, in this utility model, the aforementioned corner-cutting mold includes a 90° non-cutting mold and a 90° cutting mold, wherein the 90° non-cutting mold is located between the aforementioned punching mold and the aforementioned 90° cutting mold.

[0010] Furthermore, in this utility model, the aforementioned 90° non-cutting mold includes a first lower mold frame and a first upper mold frame connected by a guide rod, and an ejector device disposed on the first lower mold frame. The first upper mold frame is slidably connected to the guide rod. A die is disposed on the side wall of the first lower mold frame near the first upper mold frame, and a punch adapted to the die is disposed on the side wall of the first upper mold frame near the first lower mold frame. The sliding direction of the first upper mold frame is parallel to the central axis of the guide rod. A punch is disposed inside the punch, and the punch has two interconnected cutting side walls, which are perpendicular to each other.

[0011] Furthermore, in this utility model, the punching die includes a second lower die frame and a second upper die frame connected by precision guide pillars. The second upper die frame is slidably connected to the precision guide pillars. A contouring die is provided on the side wall of the second lower die frame near the side wall of the second upper die frame. A contouring punch adapted to the contouring die is provided on the side wall of the second upper die frame near the side wall of the second lower die frame. A punching pin is provided on the side wall of the contouring punch near the side wall of the contouring die. The central axis of the punching pin and the sliding direction of the second upper die frame are both parallel to the central axis of the precision guide pillars.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a strip forming system. The strip is conveyed by a feeding device and passes through a roll forming machine, a punching die, a 90° non-cutting die and a 90° cutting die in sequence.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution:

[0022] A strip forming system includes a feeding device 1, a roll forming machine 2, a punching die 3, and a corner-cutting die 4, which are arranged in a straight line. The feeding device 1 is used to transport the strip 5 to be processed to the roll forming machine 2. In this embodiment, the feeding device 1 adopts a belt conveyor mechanism. The corner-cutting die 4 can cut or partially cut the formed and punched strip 5. The roll forming machine 2 adopts equipment commonly used in the prior art, and its structure and working principle are all prior art, so they will not be described in detail here.

[0023] After the pressing strip 5 is rolled and formed on the rolling forming machine 2, it continues to move to the punching die 3, where the punching die 3 punches out the corresponding threaded holes on the pressing strip 5. For details, refer to... Figure 5 In this embodiment, the punching die 3 includes a second lower die frame 302 and a second upper die frame 303 connected by a precision guide post 301. The second upper die frame 303 is slidably connected to the precision guide post 301. A contouring die 304 is mounted on the top of the second lower die frame 302, and a contouring punch 305 adapted to the contouring die 304 is mounted on the bottom of the second upper die frame 303. A punching pin 306 is located at the bottom of the contouring punch 305. The central axis of the punching pin 306 and the sliding direction of the second upper die frame 303 are both parallel to the central axis of the precision guide post 301. When the rolled strip 5 moves onto the contouring die 304, the second upper die frame 303 moves downward under the control of a corresponding control mechanism, so that the contouring punch 305 and the punching pin 306 move downward synchronously. The punching pin 306 can then pierce the strip 5 to punch out the required hole in the strip 5.

[0024] In this embodiment, the corner cutting mold 4 is divided into two molds, including a 90° non-cutting mold 41 and a 90° cutting mold 42, and the 90° non-cutting mold 41 is located between the punching mold 3 and the 90° cutting mold 42.

[0025] Specifically, refer to Figure 2 and Figure 3 The 90° non-cutting mold 41 includes a first lower mold base 412 and a first upper mold base 413 connected by a guide rod 411, and an ejector device 414 mounted on the first lower mold base 412. The first upper mold base 413 is slidably connected to the guide rod 411. A die 415 is mounted on the top of the first lower mold base 412, and a punch 416 adapted to the die 415 is mounted on the bottom of the first upper mold base 413. The sliding direction of the first upper mold base 413 is parallel to the central axis of the guide rod 411. A punch 417 is mounted inside the punch 416. The punch 417 has two interconnected cutting sidewalls that are perpendicular to each other. In this embodiment, the ejector device 414 is a cylinder, and its actuating end is connected to a push block. After the pressure strip 5, which is punched by the punching die 3, is moved to the die cavity 415, the ejector device 414 first fixes the pressure strip 5 on the first lower die set 412. Then, the first upper die set 413 moves downward under the control of the corresponding control mechanism so that the punch 416 and the punch 417 inside the punch 416 move downward synchronously. The punch 417 can then cut a certain notch in the pressure strip 5.

[0026] Reference Figure 3 and Figure 4 The only structural difference between the 90° cutting die 42 and the 90° non-cutting die 41 is that the 90° cutting die 42 also has a rectangular strip with a rectangular cross-section installed at the connection between the two cutting sidewalls. Figure 4 From the perspective of the 90° cutting die 42, since a rectangular strip is installed at the connection of the two cutting side walls, the presence of this rectangular strip can increase the size of the punch 417 in the left and right directions, thereby enabling a complete cutting operation on the pressure strip 5.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
