Description

Technical Field

[0001] This utility model belongs to the field of sheet metal shearing technology, specifically relating to a shearing device for cold-formed steel sheets. Background Technology

[0002] Cold-formed steel sheets refer to steel profiles formed by bending metal sheets into specific shapes through cold working (i.e., at room temperature, without heating or with only slight heating). This process is mainly used for steel materials, but it can also be used for other metals such as aluminum.

[0003] Problems with existing technology:

[0004] The prior art, disclosed in CN215998905U, "An Automatic Shearing Device for Cold-Formed Steel Sheet Material," "includes a shearing device body and a shearing blade block installed at the center of the shearing device body. A connecting component for replacing the shearing blade block is provided at the connection between the shearing device body and the shearing blade block. The connecting component includes a first elastic element. A through groove matching the shearing blade block is opened at the center of the shearing device body. The shearing blade block is located inside the through groove. The first elastic element is symmetrically arranged at the connection between the shearing blade block and the through groove."

[0005] The shearing device in the above-mentioned apparatus lacks an automatic feeding structure, requiring manual feeding during use. This method poses significant safety hazards. Furthermore, the absence of a pressure structure at the shearing position during shearing makes the sheared sheet material prone to bending, thus affecting the effectiveness of the shearing device. Utility Model Content

[0006] The purpose of this invention is to provide a cold-formed steel sheet shearing device that can solve the problems of insufficient safety during use of existing sheet shearing devices due to the lack of a feeding structure, and the easy bending of the sheet during the shearing process.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A cold-formed steel sheet shearing device includes a frame, a housing fixedly installed on the top of the frame, a conveyor frame provided on one side of the frame, and a slide rail fixedly installed on the top of the frame via a frame.

[0009] A feeding mechanism is slidably installed on the top of the slide rail, and a shearing mechanism is fixedly installed on the top of the frame.

[0010] The feeding mechanism includes a moving mechanism and a fixed mechanism, wherein the moving mechanism drives the sliding seat to move the fixed mechanism horizontally;

[0011] The moving mechanism includes a first motor and a connecting seat. A lead screw is driven to one side of the first motor, and the connecting seat is threadedly installed with the lead screw.

[0012] The fixing mechanism includes a fixing frame, a cylinder, and a second motor. The cylinder drives the moving seat to move the pressure block vertically, and the second motor drives the bidirectional screw to move the pressure block axially.

[0013] The moving mechanism is used to drive the sliding seat to move horizontally on the top of the slide rail, so that the feeding mechanism moves toward the shearing mechanism.

[0014] The first motor is fixedly installed on the frame. The first motor drives the lead screw to rotate, so that the connecting seat drives the sliding seat and the fixing mechanism to move synchronously.

[0015] The fixed frame is fixedly installed on the top of the sliding seat, and a cylinder is fixedly installed on the top of the fixed frame. A sliding rod is fixedly installed on the top of the movable seat, so that the movable seat and the fixed frame are slidably installed.

[0016] Two sets of pressure blocks are provided and are threadedly installed with the bidirectional screw, which is rotatably installed inside the movable seat.

[0017] The shearing mechanism includes a mounting frame, a hydraulic cylinder, a shearing blade, and a pressure seat. A top plate is fixedly mounted on the top of the mounting frame. The hydraulic cylinder drives the blade holder to move the shearing blade vertically, causing the pressure seat to move synchronously.

[0018] The tool holder is slidably installed with the mounting frame, and the pressure seat is slidably installed with the tool holder.

[0019] A spring is connected between the pressure seat and the top plate.

[0020] The technical effects achieved by this utility model are as follows:

[0021] This invention features a sliding seat at the top of a slide rail, with a moving mechanism at the bottom. When the moving mechanism is activated, the sliding seat drives the fixed mechanism toward the shearing mechanism. Simultaneously, a cylinder is installed at the top of the fixed frame. When the cylinder is activated, the moving seat drives the pressure block to clamp the sheet metal between the sliding seat and the pressure block. Thus, under the action of the moving mechanism, automatic feeding is achieved. Therefore, this device eliminates the need for manual operation when feeding sheet metal, thereby improving the safety of the shearing device and saving time and effort.

[0022] This invention features a top plate mounted on the top of the mounting frame, with a hydraulic cylinder installed on top of the top plate. The hydraulic cylinder causes the cutter holder to move the pressure seat downwards synchronously. Since the pressure seat and the cutter holder are slidably installed, and the pressure seat contacts the sheet material first under the action of the spring, bending at the cutting position can be avoided during the shearing process, thereby improving the effectiveness of the shearing device.

[0030] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0031] like Figure 1-5 As shown, a cold-formed steel sheet shearing device includes a frame 1, a housing 2 fixedly installed on the top of the frame 1, a conveyor frame 3 provided on one side of the frame 1, and a slide rail 5 fixedly installed on the top of the frame 1 through a frame 4.

[0032] A feeding mechanism 6 is slidably installed on the top of the slide rail 5, and a shearing mechanism 7 is fixedly installed on the top of the frame 4.

[0033] The feeding mechanism 6 includes a moving mechanism 61 and a fixed mechanism 63. The moving mechanism 61 drives the sliding seat 62 to drive the fixed mechanism 63 to move horizontally.

[0034] The moving mechanism 61 includes a first motor 611 and a connecting seat 613. A lead screw 612 is drivenly connected to one side of the first motor 611, and the connecting seat 613 is threadedly installed with the lead screw 612.

[0035] The fixing mechanism 63 includes a fixing frame 631, a cylinder 632, and a second motor 634. The cylinder 632 drives the moving seat 633 to move the pressure block 636 vertically, and the second motor 634 drives the bidirectional screw 635 to move the pressure block 636 axially.

[0036] See attached document Figure 2 , Figure 3 and Figure 4 In this embodiment, the moving mechanism 61 is used to drive the sliding seat 62 to move horizontally on the top of the slide rail 5, so that the feeding mechanism 6 moves toward the shearing mechanism 7.

[0037] In the above embodiment, the sliding seat 62 can be moved by activating the moving mechanism 61. Since the fixing mechanism 63 at the top of the sliding seat 62 can clamp and fix the sheet material, the sheet material can be sent to the shearing mechanism 7 for shearing when the feeding mechanism 6 moves.

[0038] Specifically, the first motor 611 of the moving mechanism 61 is fixedly installed with the frame 4, and the first motor 611 can drive the lead screw 612 to rotate. Since the lead screw 612 is threadedly installed with the connecting seat 613, the sliding seat 62 and the fixed mechanism 63 can be driven to move synchronously through the connecting seat 613.

[0039] More specifically, the fixing frame 631 is fixedly installed on the top of the sliding seat 62, and the top of the fixing frame 631 is fixedly installed with a cylinder 632. The cylinder 632 can drive the moving seat 633 to move the pressure block 636, so that the pressure block 636 cooperates with the sliding seat 62 to clamp and fix the sheet material. At the same time, a sliding rod is fixedly installed on the top of the moving seat 633, so that the moving seat 633 and the fixing frame 631 can be slidably installed.

[0040] Furthermore, a second motor 634 is fixedly installed on one side of the movable base 633. The second motor 634 is connected to the bidirectional screw 635 for transmission. Two sets of pressure blocks 636 are provided and threadedly installed with the bidirectional screw 635. The bidirectional screw 635 is rotatably installed inside the movable base 633. Therefore, when the second motor 634 is started, the spacing between the two sets of pressure blocks 636 can be adjusted, making it suitable for fixing plates of different sizes.

[0041] See attached document Figure 1 , Figure 2 and Figure 5 In this embodiment, the shearing mechanism 7 includes a mounting frame 71, a hydraulic cylinder 73, a shearing blade 75, and a pressure seat 76. A top plate 72 is fixedly mounted on the top of the mounting frame 71. The hydraulic cylinder 73 drives the blade holder 74 to move the shearing blade 75 vertically, causing the pressure seat 76 to move synchronously.

[0042] In the above embodiment, the feeding mechanism 6 can feed the sheet material between the cutter holder 74 and the mounting frame 71, while the hydraulic cylinder 73 can drive the cutter holder 74 and the shearing blade 75 to move, thereby realizing the shearing of the sheet material.

[0043] Furthermore, the tool holder 74 is slidably mounted to the mounting frame 71, and the pressure seat 76 is slidably mounted to the tool holder 74. At the same time, a spring 77 is abutting between the pressure seat 76 and the top plate 72. Therefore, under the action of the spring 77, when the tool holder 74 moves, it can drive the pressure seat 76 to move synchronously. The spring 77 can make the pressure seat 76 contact the sheet material first and fix the sheet material, thereby preventing the sheet material from bending.

[0044] The working principle of this utility model is as follows: The sheet material is placed on top of the conveyor frame 3. The first motor 611 is started, driving the lead screw 612 to rotate. This causes the connecting seat 613 to move the sliding seat 62 and the fixing mechanism 63 towards the sheet material to a suitable position. One end of the sheet material is then fed between the pressure block 636 and the sliding seat 62. The cylinder 632 is started, causing the moving seat 633 to move the pressure block 636 downwards to clamp and fix the sheet material. Under the action of the moving mechanism 61, the sheet material moves towards the shearing mechanism 7 and enters between the shearing blade 75 and the mounting frame 71. The cylinder 632 is started again, causing the moving seat 633 to move upwards. This releases the clamping of the sheet metal. Under the action of the moving mechanism 61, the fixing mechanism 63 returns a certain distance and can clamp and fix the sheet metal again. Under the action of the moving mechanism 61, the sheet metal is transported to the shearing mechanism 7. Therefore, by using the cycle start-stop cylinder 632 and the first motor 611, and linking with the shearing mechanism 7, the automatic shearing and feeding of the sheet metal is realized. During the shearing process, the hydraulic cylinder 73 causes the blade holder 74 to move the pressure seat 76 downward. Under the action of the spring 77, the pressure seat 76 first contacts and fixes the sheet metal. Then, the shearing blade 75 moves downward to complete the shearing of the sheet metal.

[0045] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
