[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0037] Please see Figure 1-8 The present invention provides the following technical solution:

[0038] Example 1, see Figure 1 A punching mechanism for cutting and pulling materials with different strengths on both sides includes a placement component 1. Above the placement component 1, a conveying component 3, two sets of guiding components 4, a punching component 5, a material pulling component 6, and a limiting component 7 are arranged in sequence. A workpiece 2 is arranged in the middle position of the punching component 5.

[0039] In the actual processing, workpiece 2 is conveyed by conveying component 3, and two sets of guiding components 4 limit workpiece 2. When workpiece 2 reaches the position of stamping component 5, stamping component 5 punches workpiece 2. The remaining strip after being punched by stamping component 5 is pulled up by material pulling component 6, completing one processing of electronic products.

[0040] The workpiece 2 is in two different states: when it is in the position of the conveying component 3, it is in the position of the pulling component 6. When the workpiece 2 is in the position of the conveying component 3, it is in the un-punched state. When the workpiece 2 is in the position of the pulling component 6, it is in the punched state. That is, the workpiece 2 has completed the processing of electronic products at the position of the stamping component 5.

[0041] Since the workpiece 2 is in different states on both sides of the stamping assembly 5, different conveying and pulling devices of different strengths are set for the workpiece 2 on both sides of the stamping assembly 5, that is, the workpiece 2 is conveyed by the conveying assembly 3 and the workpiece 2 is pulled by the pulling assembly 6.

[0042] During the conveying process of the conveying component 3 to the workpiece 2, the conveying component 3 achieves the conveying force of the workpiece 2, and at the same time, the guide component 4 provides assistance so that the workpiece 2 can complete the punching work normally at the position of the stamping component 5.

[0043] During the process of the pulling component 6 pulling the workpiece 2, the pulling component 6 drives the workpiece 2 to move horizontally. After the pulling component 6 pulls the workpiece 2, the limiting component 7 provides auxiliary limiting to reduce the possibility of the workpiece 2 retracting.

[0044] The state of the workpiece 2 on both sides of the stamping assembly 5 is controlled by the combination of the conveying component 3, the guiding component 4, the pulling component 6, and the limiting component 7, so that the workpiece 2 can complete the punching normally at the position of the stamping assembly 5 and continue to complete the subsequent pulling work, thus meeting the different strength requirements of the workpiece 2 on both sides of the stamping assembly 5.

[0045] See Figure 2 and Figure 3 The placement component 1 includes a worktable 11, and a guide rail 12 is provided on the top of the worktable 11.

[0046] The workbench 11 provides a platform for the entire device, and the guide rail 12 provides a channel for the material pulling assembly 6 to be pulled. The material pulling assembly 6 is located on top of the guide rail 12.

[0047] See Figure 2 and Figure 5 The conveying assembly 3 includes a limiting roller 31, a conveying roller 33 is arranged above the limiting roller 31, and a motor 32 is arranged on one side of the conveying roller 33.

[0048] See Figure 2 and Figure 5 At the top of 11, motor 32 is located on one side of one set of limiting rollers 31. The output end of motor 32 passes through mounting frame 34 and is connected to conveying roller 33. Workpiece 2 is located at the middle position between conveying roller 33 and limiting roller 31.

[0049] Two sets of mounting brackets 34 are located on the top of the workbench 11, and the two sets of mounting brackets 34 are used to provide installation space for the conveyor roller 33 and the motor 32.

[0050] The motor 32 provides the power to rotate the conveyor roller 33. When the motor 32 starts, it can drive the conveyor roller 33 to rotate. Under the action of the rotation of the conveyor roller 33, the workpiece 2 is driven by the conveyor roller 33 to be conveyed.

[0051] A motor 32 is installed below the conveyor roller 33. The motor 32 limits the lower part of the workpiece 2, so that the conveyor roller 33 can drive the workpiece 2 to be conveyed.

[0052] After the workpiece 2 is conveyed by the conveying roller 33, the workpiece 2 may deform under the action of the conveying roller 33. For example, the workpiece 2 may be bent under the conveying roller 33. When the bent workpiece 2 is conveyed to the stamping assembly 5, the stamping assembly 5 will have errors in processing the workpiece 2. Therefore, by setting the guide assembly 4 to assist in limiting the workpiece 2, the workpiece 2 is placed horizontally when it reaches the stamping assembly 5, which facilitates the processing of the workpiece 2 by the stamping assembly 5 and improves the processing effect of the stamping assembly 5 on the workpiece 2.

[0053] See Figure 7 and Figure 8 The guide component 4 includes a limiting block 41, a column 42 is provided at the bottom of the limiting block 41, and an adapter block 43 is provided on one side of the column 42. The height of the adapter block 43 is lower than the height of the column 42.

[0054] Among them, the guide component 4 is provided in two sets. The two sets of guide components 4 are symmetrically arranged and can limit the workpiece 2 on both sides, so that the workpiece 2 can move in the horizontal direction after being output by the conveying component 3.

[0055] The length of the limiting block 41 is greater than the length of the column 42 and the adapter block 43. When the workpiece 2 output by the conveying assembly 3 is first conveyed along the limiting block 41, and then due to the height difference between the column 42 and the adapter block 43, the adapter block 43 is set close to the column 42, and the limiting block 41 is set above the column 42 and the adapter block 43, at this time, the height difference between the column 42 and the adapter block 43 and the limiting block 41 can form a conveying channel. Therefore, the workpiece 2 guided by the limiting block 41 is then conveyed by the conveying channel formed by the column 42 and the adapter block 43.

[0056] Since there are two sets of guide components 4, there are two sets of conveying channels. The two sets of conveying channels can provide conveying space on both sides of the workpiece 2. After the workpiece 2 is conveyed by the conveying component 3, it immediately enters the conveying channel for conveying, reducing the possibility of workpiece 2 deformation and facilitating the normal operation of the subsequent stamping component 5.

[0057] After the workpiece 2 is conveyed along the two sets of conveying channels, the workpiece 2 reaches the position of the stamping assembly 5, and the workpiece 2 is punched by the stamping assembly 5.

[0058] See Figure 2 and Figure 3 The stamping assembly 5 includes an upper die 55, a cutter 53 is provided at the bottom of the upper die 55, and a lower die 56 is provided below the cutter 53.

[0059] See Figure 2 and Figure 3 The stamping assembly 5 also includes a mounting base 57, on the top of which are provided four sets of slide bars 54, and the lower die 56 is located in the middle of the four sets of slide bars 54.

[0060] See Figure 2 and Figure 3 An upper mold 55 is provided above the mounting base 57. A mounting plate 52 is provided on the side of the upper mold 55 away from the mounting base 57. Four sets of sliding rods 54 pass through the upper mold 55 and are connected to the mounting plate 52 respectively. The four sets of sliding rods 54 are slidably connected to the upper mold 55 respectively. A hydraulic cylinder 51 is provided on the top of the mounting plate 52. The output end of the hydraulic cylinder 51 passes through the mounting plate 52 and is connected to the upper mold 55.

[0061] The lower mold 56 has a hollow channel in the middle, and a collection box is set inside the worktable 11 opposite to the hollow channel. The collection box is used to collect the punched electronic products.

[0062] Specifically, the hydraulic cylinder 51 is activated, which drives the upper mold 55 to move downward along the four sets of slide bars 54. The upper mold 55 gradually approaches the lower mold 56. When the upper mold 55 contacts the lower mold 56, the cutter 53 punches the workpiece 2. The punched product falls into the collection box through the hollow channel in the middle of the lower mold 56.

[0063] After workpiece 2 is punched, the remaining strip is pulled up by the pulling component 6. The pulling component 6 adjusts workpiece 2 to the next punching position, which facilitates the normal operation of subsequent punching work.

[0064] See Figure 4 and Figure 6 The material pulling assembly 6 includes a base 61, a material pulling cylinder 66 is provided below the base 61, the output end of the material pulling cylinder 66 is connected to the base 61 through a connecting shaft, two sets of sliding rods 62 are symmetrically arranged on the top of the base 61, a tension block 63 is provided above the base 61, and a top plate 64 is provided at the end of the tension block 63 away from the base 61.

[0065] See Figure 4 and Figure 6 Two sets of sliding rods 62 pass through the tension block 63 and are connected to the top plate 64 respectively. The two sets of sliding rods 62 are slidably connected to the tension block 63 respectively. A telescopic cylinder 65 is provided on the top of the top plate 64. The output end of the telescopic cylinder 65 passes through the top plate 64 and is connected to the tension block 63.

[0066] The base 61 has a slider at its bottom, the top of the slider is connected to the base 61, and the bottom of the slider is slidably connected to the guide rail 12. The base 61 is connected to the material pulling cylinder 66 through a connecting shaft. When the material pulling cylinder 66 is activated, it can drive the slider to move horizontally along the guide rail 12 through the connecting shaft. Thus, the base 61 moves horizontally under the action of the slider. When the base 61 moves horizontally, the sliding rod 62, the stretching block 63, the top plate 64, and the telescopic cylinder 65 at the top of the base 61 move horizontally along with it.

[0067] In addition, the stretching block 63 is composed of a first connector and a second connector. The first connector is a component that is slidably connected to the two sets of sliding rods 62, and the second connector is a component that pulls up the workpiece 2. In actual application, the second connector is in contact with the workpiece 2.

[0068] The specific process of workpiece 2 being pulled out is as follows:

[0069] After punching is completed, the telescopic cylinder 65 is activated. The telescopic cylinder 65 drives the stretching block 63 to move vertically downward along the two sets of sliding rods 62 until the second connecting piece of the stretching block 63 contacts the workpiece 2. The second connecting piece limits the workpiece 2 and reduces the shaking of the workpiece 2. Then the pulling cylinder 66 is activated. The pulling cylinder 66 drives the base 61 to move as a whole through the connecting shaft. At this time, since the workpiece 2 is limited by the second connecting piece, the workpiece 2 moves horizontally along with the base 61 as a whole, thereby achieving the purpose of pulling the workpiece 2.

[0070] After being pulled up, the workpiece 2 is limited by the limiting component 7 during the conveying process, and the limiting component 7 assists in the normal operation of the pulling work.

[0071] See Figure 4 and Figure 6 The limiting component 7 includes a base plate 71, a bracket 72 is provided on the top of the base plate 71, a limiting plate 73 is provided above the bracket 72, and two sets of adjusting cylinders 74 are symmetrically arranged in the middle of the bracket 72. The output ends of the two sets of adjusting cylinders 74 pass through the bracket 72 and are respectively connected to the limiting plate 73.

[0072] Two sets of adjusting cylinders 74 are slidably connected to the bracket 72. When the two sets of adjusting cylinders 74 are activated, the two sets of adjusting cylinders 74 can drive the limiting plate 73 to move down. The limiting plate 73 moves down and contacts the workpiece 2. When the workpiece 2 is limited by the second connecting piece of the stretching block 63, the limiting plate 73 can first limit the workpiece 2. Then, the second connecting piece of the stretching block 63 releases the workpiece 2 under the action of the telescopic cylinder 65. The pulling action is then realized again under the action of the pulling cylinder 66.

[0073] When the material pulling assembly 6 pulls the material, the limiting plate 73 moves away from the workpiece 2. After the material pulling assembly 6 finishes pulling the material, the limiting plate 73 can limit the workpiece 2, reducing the possibility of displacement of the workpiece 2 when the material pulling assembly 6 pulls it again.

[0074] Obviously, the embodiments described above 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 should fall within the protection scope of this utility model.
