Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, specifically relating to a CNC bending machine mold changing mechanism. Background Technology

[0002] A CNC bending machine is a type of bending machine controlled by computer numerical control technology. It can precisely control the angle and position during the bending process, thereby achieving high-precision and high-efficiency bending operations. This type of machine is widely used in industries such as automotive, light industry, and hardware to process metal sheets of various complex shapes. When processing metal sheets, bending dies are usually required.

[0003] When processing different products, different types of molds need to be changed to meet these processing requirements. Some molds are fixed with bolts. When changing molds, manual replacement with the help of workpieces is required. Manual mold replacement is time-consuming, reduces production efficiency, and affects the overall normal schedule. Utility Model Content

[0004] The purpose of this invention is to provide a CNC bending machine mold changing mechanism that can quickly and automatically change the mold, shorten the mold change time, enable the production line to adapt to the needs of different products more quickly, reduce downtime, and improve the overall efficiency of product processing.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] The machine includes a bending machine body, a processing table, and a bending die. The processing table is set on the table surface of the bending machine body, and the bending die is installed on the top of the processing table. The interior of the processing table is hollow, and a fastening mechanism is provided inside the processing table. The fastening mechanism includes a horizontal plate, inclined grooves, cylinders, connecting rods, connecting columns, fasteners, and an electric telescopic rod. The horizontal plate is movably set inside the processing table. The inclined grooves are opened at the top of the horizontal plate and penetrate through the horizontal plate. There are several inclined grooves, which are evenly distributed at the top of the horizontal plate. The inclined grooves are octagonal in shape. The cylinders are slidably connected to the interior of the inclined grooves. The connecting rods are fixedly connected to the top of the cylinders. One end of each connecting column is fixedly connected to the top of the connecting rod, and the other end of the connecting column penetrates to the top of the processing table. The fasteners are fixedly connected to the top of the connecting column. The electric telescopic rod is fixedly installed inside the processing table, and the output end of the electric telescopic rod is fixedly connected to the horizontal plate.

[0007] Preferably, sliders are fixedly connected to both sides of the horizontal plate, and slide rods are fixedly connected to the inner wall of the processing table, with the sliders slidably connected to the surfaces of the slide rods respectively.

[0008] Preferably, the top of the processing table is equipped with limit posts, which are located on the front and rear sides of the bending die, respectively.

[0009] Preferably, the top of the processing table is provided with several horizontal grooves, and the connecting columns are slidably connected to the inside of the horizontal grooves.

[0010] Preferably, the processing table is internally fixedly connected to a limiting rod, and the connecting rods are slidably connected to the surface of the limiting rod.

[0011] Preferably, a ring is fitted onto the bottom of the cylindrical surface, and the ring is located at the bottom of the horizontal plate.

[0012] Preferably, there are several electric telescopic rods, which are evenly installed inside the processing table.

[0013] The technical effects achieved by this utility model are as follows:

[0014] In this invention, the use of a fastening mechanism allows for quick and automatic replacement of bending dies. The electric telescopic rod retracts inward, causing the horizontal plate to move forward. This forward movement compresses the cylinder, which slides outward along the inclined groove in an outward octagonal trajectory. Simultaneously, the cylinder's outward sliding causes the connecting rod and connecting column to move outward. The outward sliding of the connecting column causes the fasteners to slide outward, thus removing the limiting fastener position on the bending die. The operator then removes the die from the processing table and places the new bending die between the fasteners on the processing table. The fastening mechanism is then activated again, extending the output rod of the electric telescopic rod and pushing the horizontal plate backward. This reverses the process, securing the new bending die onto the processing table. This allows for rapid and automatic die replacement, reducing downtime and improving overall product processing efficiency.

[0015] In this invention, when the electric telescopic rod moves the horizontal plate, the horizontal plate will cause the slider to slide on the surface of the sliding rod. With the cooperation of the slider and the sliding rod, the vertical movement of the horizontal plate can be restricted. When the horizontal plate moves vertically, it can squeeze the cylinder to slide smoothly along the direction of the inclined groove, and allow the cylinder to move freely outward or inward, thus assisting the fastening mechanism to operate normally.

[0021] 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.

[0022] like Figure 1-3 As shown, the CNC bending machine die changing mechanism includes a bending machine body 1, a processing table 101, and a bending die 102. The processing table 101 is set on the table surface of the bending machine body 1, and the bending die 102 is installed on the top of the processing table 101. The interior of the processing table 101 is hollow, and a fastening mechanism is provided inside the processing table 101. The fastening mechanism includes a horizontal plate 201, a sloping groove 202, a cylinder 203, a connecting rod 204, a connecting column 205, a fastener 206, and an electric telescopic rod 207. The horizontal plate 201 is movably set inside the processing table 101. The sloping groove 202 is opened at the top of the horizontal plate 201 and penetrates through the horizontal plate 201. There are several sloping grooves 202, which are evenly distributed on the top of the horizontal plate 201. The sloping groove 202 is outwardly octagonal. The bending die 102 is slidably connected to the inside of the inclined groove 202. The connecting rod 204 is fixedly connected to the top of the cylinder 203. One end of the connecting column 205 is fixedly connected to the top of the connecting rod 204, and the other end of the connecting column 205 extends to the top of the processing table 101. Fasteners 206 are fixedly connected to the top of the connecting column 205. The electric telescopic rod 207 is fixedly installed inside the processing table 101. The output end of the electric telescopic rod 207 is fixedly connected to the horizontal plate 201. Through the cooperation of the fastening mechanism, the bending die 102 can be automatically and quickly changed, reducing labor intensity, reducing manual intervention and the time required for manual replacement of the bending die 102, reducing equipment downtime, and improving the normal efficiency of the equipment.

[0023] like Figure 2-3As shown, sliders 208 are fixedly connected to both sides of the horizontal plate 201, and slide rods 209 are fixedly connected to the inner wall of the processing table 101. The sliders 208 are slidably connected to the surface of the slide rods 209. When the electric telescopic rod 207 drives the horizontal plate 201 to move, the horizontal plate 201 will drive the sliders 208 to slide on the surface of the slide rods 209. With the cooperation of the sliders 208 and the slide rods 209, the vertical movement of the horizontal plate 201 can be restricted. When the horizontal plate 201 moves vertically, it can squeeze the cylinder 203 to slide smoothly along the direction of the inclined groove 202, and allow the cylinder 203 to move freely outward or inward, which helps the fastening mechanism to operate normally.

[0024] like Figure 1-2 As shown, a limiting post 3 is installed on the top of the processing table 101. The limiting post 3 is located on the front and rear sides of the bending die 102. When the bending die 102 is installed, it can be stably limited on the processing table 101 with the assistance of the limiting post 3, so as to avoid uneven force and displacement when the bending die 102 is squeezed and fixed.

[0025] like Figure 1 As shown, the top of the processing table 101 is provided with several horizontal grooves 4, and the connecting column 205 is slidably connected to the inside of the horizontal groove 4. When the connecting column 205 drives the fastener 206 to limit the installation of the bending die 102, the connecting column 205 will slide flexibly inside the horizontal groove 4, so that the connecting column 205 has sufficient moving space, and can fix the bending die 102 of different sizes, thereby improving the applicability of the fastening mechanism.

[0026] like Figure 2 As shown, a limiting rod 5 is fixedly connected inside the processing table 101. Connecting rods 204 are slidably connected to the surface of the limiting rod 5. When the connecting rod 204 drives the connecting column 205 to move, the connecting rod 204 will slide parallel to the surface of the limiting rod 5. This not only assists the connecting rod 204 to slide parallel, but also restricts the connecting rod 204 from driving the connecting column 205 to move parallel, thus preventing uneven force distribution when the horizontal plate 201 squeezes the cylinder 203, which would cause the top connecting rod 204 and connecting column 205 to tilt.

[0027] like Figure 3 As shown, a ring 6 is fitted onto the bottom of the surface of the cylinder 203. The ring 6 is located at the bottom of the horizontal plate 201. When the cylinder 203 slides, the ring 6 can help to limit the cylinder 203 to the inside of the inclined groove 202, thus preventing the cylinder 203 from leaving the inside of the inclined groove 202 when it slides.

[0028] like Figure 2-3As shown, there are several electric telescopic rods 207, which are evenly installed inside the processing table 101. Multiple electric telescopic rods 207 can provide a more even force application point, increase the stability of the fastening mechanism during operation, and can share the load, so as to more firmly install and limit the bending die 102 on the processing table 101.

[0029] The working principle of this utility model is as follows: When changing the bending die 102, the electric telescopic rod 207 can be operated and retracted inward. After the electric telescopic rod 207 retracts, it will drive the horizontal plate 201 to move forward. The forward movement of the horizontal plate 201 will squeeze the cylinder 203 to slide outward along the inclined groove 202 in an outward octagonal trajectory. When the cylinder 203 slides outward at the same time, it can drive the connecting rod 204 and the connecting column 205 to move outward. The outward sliding of the connecting column 205 can drive the fastener 206 to slide outward. The outward sliding of the fastener 206 can drive the fastener 206 to slide outward. Once the bending die 102 is removed from the machine, the operator removes the die from the processing table 101 and places the new bending die 102 between the fasteners 206 on the processing table 101. Then, the fastening mechanism is activated to extend the output rod of the electric telescopic rod 207 and push the horizontal plate 201 backward. The above steps can then be reversed to secure the new bending die 102 onto the processing table 101. This allows for quick and automatic replacement of the bending die 102, reducing downtime and improving the overall efficiency of product processing.

[0030] 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.
