Description

Technical Field

[0001] This utility model belongs to the field of steel plate bending technology, and specifically relates to a steel plate bending device. Background Technology

[0002] Steel plates are sheet metal produced through metal processing. They have high hardness and a long service life, and can be found in various fields. Steel plates need to undergo different processing when they are manufactured into different items. Some steel plates need to be cut, while others need to be bent. For bending steel plates, a steel plate bending machine is required.

[0003] Problems with existing technology: Currently, existing steel plate bending machines typically require manual measurement and marking of the steel plate using measuring tools before bending can begin. This method is prone to marking loss and cannot be verified, thus affecting bending accuracy. In addition, the existing bending die structure is relatively simple, requiring frequent replacements, which in turn affects bending efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a steel plate bending machine that can conveniently and accurately control bending through a limiting mechanism and a laser rangefinder set at the top of the frame. Therefore, it can improve bending accuracy and facilitate measurement and positioning. At the same time, by improving the bending mold, bending efficiency can also be improved.

[0005] The specific technical solution adopted by this utility model is as follows: A steel plate bending machine includes a frame, on the top of which a side plate is fixedly mounted; A bending mold is provided on one side of the side plate, and a limit mechanism is provided on the top of the frame; The limiting mechanism includes an adjusting rod rotatably installed inside the side plate. The adjusting rod is used to drive the gear to mesh with the toothed plate, and the toothed plate is used to drive the sliding seat and the baffle to move linearly, so that the baffle moves axially to one side of the bending pressure plate.

[0006] A hydraulic cylinder is fixedly installed inside the frame. The output shaft of the hydraulic cylinder abuts against one end of the connector. The hydraulic cylinder is used to push the connector to rotate on the surface of the shaft.

[0007] The other end of the connector is hinged to the top of the bending plate, which is slidably mounted on one side of the side plate, so that the hydraulic cylinder pushes the bending plate to move vertically through the connector.

[0008] The sliding seat is provided in two sets, and the baffle is fixedly installed on the top of the sliding seat. The top of the baffle is provided with a vertical plate, and the vertical plate and the baffle are an integral structure.

[0009] The sliding seat is slidably installed with the side plate, and a laser rangefinder is fixedly installed on one side of the upright plate.

[0010] The toothed plate is correspondingly arranged with the sliding seat, and two sets of the toothed plate and gear are correspondingly arranged.

[0011] The bending die includes a limiting block fixedly installed on the top of the frame, and one side of the limiting block is inserted into the die body through a cross groove.

[0012] The technical effects achieved by this utility model are as follows: This invention utilizes an adjusting rod rotatably mounted inside the side plate. Rotating the adjusting rod drives the gear to rotate. Through the meshing of the gear and the gear plate, the sliding seat drives the laser rangefinder to move linearly via the baffle and the upright plate, thereby adjusting the distance between the laser emitted by the laser rangefinder and the bending pressure plate. Therefore, this device eliminates the need for manual pre-measurement marking during use, effectively improving bending accuracy and facilitating bending measurement.

[0013] This invention features four bending grooves of different specifications on the four axes of the mold body, and cross grooves at both ends of the mold body. The mold body can be fixed to the top of the frame by the insertion of the cross grooves and the limiting block. Therefore, compared with the existing single bending mold that needs to be frequently replaced during use, the bending mold of this device is more convenient and flexible to use.

Detailed Implementation

[0016] 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.

[0017] like Figure 1-4 As shown, a steel plate bending machine includes a frame 1, and a side plate 2 is fixedly installed on the top of the frame 1. A bending die 6 is provided on one side of the side plate 2, and a limit mechanism 7 is provided on the top of the frame 1; The limiting mechanism 7 includes an adjusting rod 73 rotatably installed inside the side plate 2. The adjusting rod 73 is used to drive the gear 74 to mesh with the toothed plate 75. The toothed plate 75 is used to drive the sliding seat 72 and the baffle 71 to move linearly, so that the baffle 71 moves axially to one side of the bending pressure plate 5.

[0018] See attached document Figure 1 , Figure 2 and Figure 4 In this embodiment, a hydraulic cylinder 8 is fixedly installed inside the frame 1. The output shaft of the hydraulic cylinder 8 abuts against one end of the connector 4. The hydraulic cylinder 8 is used to push the connector 4 to rotate on the surface of the rotating shaft 3.

[0019] In the above embodiment, since the other end of the connector 4 is hinged to the top of the bending pressure plate 5, and the bending pressure plate 5 is slidably installed on one side of the side plate 2, when the hydraulic cylinder 8 is activated to push one end of the connector 4 to swing, the connecting shaft 3 can be driven to rotate through the connector 4, and at the same time the other end of the connector 4 flips and rotates, and pushes the bending pressure plate 5 to move vertically.

[0020] Furthermore, the bottom of the bending pressure plate 5 is at the same level as the bending groove of the bending die 6, and the steel plate is located between the bending pressure plate 5 and the bending die 6. Therefore, during the downward movement of the bending pressure plate 5, the steel plate at the top of the bending die 6 can be bent.

[0021] It should be noted that the limiting block 63 of the bending die 6 is fixedly installed on the top of the frame 1, and a cross groove 62 is provided on one side of the die body 61. By inserting the limiting block 63 into the cross groove 62, the die body 61 can be limited and fixed by the limiting block 63. Since four different bending grooves are provided around the circumference of the die body 61, it is possible to easily switch between different bending effects. Furthermore, since a limiting mechanism 7 is also installed on the top of the frame 1, the limiting mechanism 7 can limit the end of the steel plate at a fixed distance, thereby improving the bending accuracy of the steel plate.

[0022] Please refer to the appendix for details. Figure 2 and 3The limiting mechanism 7 has two sets of sliding seats 72, and the baffle 71 is fixedly installed on the top of the sliding seat 72. The toothed plate 75 is correspondingly set with the sliding seat 72. Therefore, when the baffle 71 is manually driven to drive the gear 74 to rotate, the sliding seat 72 can be driven to drive the baffle 71 to adjust axially through the meshing of the gear 74 and the toothed plate 75.

[0023] More specifically, the upright plate 76 and the baffle 71 are an integral structure. At the same time, a laser rangefinder 77 is fixedly installed on one side of the upright plate 76. The rangefinder 77 emits a range-measuring laser that irradiates the surface of the bending pressure plate 5, thus achieving fixed-distance positioning of the steel plate and ensuring the accuracy and effect of bending.

[0024] The working principle of this utility model is as follows: According to the specific bending requirements, the gear 74 is driven to rotate by manually driving the adjusting rod 73, so that the gear 74 drives the sliding seat 72 to move axially through the toothed plate 75. In turn, the sliding seat 72 drives the laser rangefinder 77 to move synchronously through the baffle 71 and the upright plate 76. The laser beam emitted by the laser rangefinder 77 is irradiated on the back of the bending pressure plate 5. By observing the data of the laser rangefinder 77 and cooperating with the adjusting rod 73, the bending accuracy can be controlled. After the steel plate is sent between the bending pressure plate 5 and the bending mold 6, the hydraulic cylinder 8 can be activated to push the connecting piece 4 to move the bending pressure plate 5 down and bend the steel plate. When it is necessary to change the bending effect, simply remove the limit block 63 and rotate the mold body 61 ninety degrees to achieve flexible switching of the bending effect.

[0025] 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.
