[0002] Punching processing refers to punching various patterns on metal parts, leather, cloth, wood and other materials to meet different needs. During the processing of metal parts, punching operations are often required.

[0003] The main method of processing holes on metal parts is mechanical processing, including drilling and milling. In mass production, punching is used instead of drilling and milling, which has the characteristics of high production efficiency and reduced processing costs. Existing metal parts need to be fixed at both ends before punching. Generally, the two ends of the metal parts are clamped by a cylinder-driven clamping block, and then the metal parts are punched by a punching machine. Although this can also punch the metal parts, the punching process is not very stable, resulting in poor punching quality. In addition, metal parts cannot be punched in batches, and the punching efficiency is low. Utility Model Content

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0016] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0017] Combination Figure 1-3As shown, the punching device includes a machine table 1, on which a material discharge table 2 is provided, a pushing mechanism is provided on one side of the material discharge table 2, and a punching mechanism is provided on the other side, the punching mechanism includes a frame 3 installed on the machine table 1, a punching machine 4 is provided on the top of the frame 3 facing downward, a mold mounting block 5 is provided on the front side of the bottom of the frame 3, and a pushing cylinder 6 is provided on the rear side, the mold mounting block 5 is provided with a mold column 7 outwardly, a mold hole 8 is opened on the mold column 7, a pushing block 9 is slidably provided on the mold column 7, a connecting block 10 is provided at the end of the driving shaft of the pushing cylinder 6, a pair of push rods 11 are provided between the connecting block 10 and the pushing block, a positioning mechanism is also provided on the front side of the pushing mechanism, and a material picking mechanism is provided between the pushing mechanism and the positioning mechanism.

[0018] This device is mainly used for punching metal pipes, such as Figure 2-3 A feeding mechanism is provided in front of the positioning mechanism, and the feeding mechanism can be a synchronous belt conveyor 31. An inclined material receiving rack 32 is provided at the end of the synchronous belt conveyor. A pushing mechanism is provided between the material receiving rack 32 and the positioning mechanism. The pushing mechanism includes a pushing rack 33. The two ends of the top of the pushing rack 33 are inclined surfaces. A pushing cylinder 34 is provided in the machine platform, and the driving shaft of the pushing cylinder 34 passes through the machine platform and is connected to the pushing rack 33.

[0019] When punching a certain amount of metal parts, the metal parts first fall onto the receiving rack one by one under the conveyance of the synchronous belt conveyor 31. At this time, the top of the push rack is flush with the end of the receiving rack, and the metal parts fall onto the push rack. At this time, the push cylinder drives the push rack to move upward, and the metal parts move upward until they are pushed onto the positioning mechanism. After that, the material picking mechanism transfers the metal parts to the unloading table, and a V-shaped groove is opened on the top surface of the unloading table. The metal parts are located in the V-shaped groove. The V-shaped groove limits the metal parts to make them more stable during the punching process.

[0020] In an embodiment, the inner diameter of the metal part is slightly larger than the outer diameter of the mold column. When the metal part is transferred to the V-shaped groove, the pusher mechanism pushes the metal part so that the metal part moves toward the mold column until the corresponding end of the metal part is inserted into the mold column and contacts the push block. At this time, the metal part is clamped and fixed, and then the punching machine punches the corresponding position of the metal part. The punching shaft of the punching machine passes through the metal part and is located in the mold hole. At this time, the punching of the metal part is completed. Next, the punching machine and the pusher mechanism return to their positions respectively, and the push cylinder drives and pushes the connecting block outward. Under the action of the push rod, the push block is pushed outward. During the movement, the metal part will be pushed outward until the metal part is separated from the mold column. Then the material taking mechanism transfers the metal part that has been punched to the receiving rack.

[0021] Before punching the metal part, the metal part is put on the mold column through the pushing mechanism, which can clamp and fix the metal part well. In addition, the metal part is put on the mold column and the inner diameter of the metal part is slightly larger than the outer diameter of the mold column. The mold column can support the punching position, which can improve the stability during punching and improve the punching quality.

[0022] In this structure, Figure 1 , Figure 3 The pushing mechanism includes a pushing rack 12, a sliding rod 13 is inserted into the pushing rack 12, a connecting plate 14 is provided at the end of the sliding rod 13, a connecting rod 15 is provided on the connecting plate 14, and a pushing plate 16 is provided at the end of the connecting rod 15, and a pushing cylinder 17 is provided on the pushing rack 12, and a driving shaft of the pushing cylinder 17 passes through the pushing rack 12 and is connected to the connecting plate 14.

[0023] When the metal part is transferred to the V-shaped groove, the push cylinder drives and pushes the connecting plate toward the unloading table, and the push plate also moves toward the unloading table and pushes the metal part until the corresponding end of the metal part is sleeved on the mold column and the metal part contacts the push block.

[0024] As a preferred structure, Figure 2 The positioning mechanism includes two left and right vertical plates, a placement groove 18 is opened in the middle of the vertical plates, a positioning plate 20 is provided on the right side of the right vertical plate 19 and the positioning plate 20 is higher than the vertical plate, a vertical frame 22 is provided on the left side of the left vertical plate 21, and a positioning cylinder 23 is provided on the vertical frame 22 facing the vertical plate, and a positioning block 24 is provided at the end of the positioning cylinder 23.

[0025] In this structure, the vertical plate and both sides of the placement slot are inclined surfaces inclined toward the placement slot. When the metal part falls on the push frame, the push cylinder drives the push frame to move upward, and the metal part is lifted to the adjacent inclined surface, and then rolls into the placement slot. Finally, the positioning cylinder drives the positioning block, and the positioning block pushes one end of the metal part toward the positioning plate until the other end of the metal part contacts the positioning plate, and the positioning block returns to its position to achieve the positioning of the metal part before taking the material.

[0026] Further as a preferred structure, the material picking mechanism includes a material picking rack 25, a slide 26 is provided on the material picking rack 25 and facing the material unloading platform, a slide seat 27 is provided on the slide 26, a material picking plate 28 is provided on the slide seat 27, and clamps 29 are provided downward at both ends of the material picking plate 28, and a material picking cylinder 30 for pushing the slide seat to slide is provided on the side wall of the material picking rack 25.

[0027] In this structure, there are two grippers, front and back, and the distance between the two grippers is equal to the distance between the placement groove and the V-shaped groove. When gripping, the front gripper grips the metal piece to be punched on the positioning mechanism, and the rear gripper grips the punched metal piece on the placement table. Then, the slide is driven backward by the material-picking cylinder until the metal piece to be punched moves above the V-shaped groove, and the punched metal piece is located on the material receiving rack. Finally, the two grippers are released at the same time, the metal piece to be punched falls on the V-shaped groove, and the punched metal piece falls on the material receiving rack for collection after punching. By setting up a material-picking mechanism to feed the metal piece before punching, the punching efficiency is improved, and the gripper is not the focus of this device, so it will not be specifically explained here.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
