Description

Technical Field

[0001] This application relates to the field of die stamping, and particularly to an inclined slide block piercing device. Background Art

[0002] A stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly known as a cold punching die).

[0003] In the related art, a conventional punching mechanism includes an upper die and a lower die. The upper die includes a punch, and the lower die is provided with a concave hole corresponding to the punch. The product is pierced through the cooperation of the punch and the concave hole, and after piercing the product, the structure at the pierced part is punched off from the product.

[0004] In the conventional process, an inclined slide block structure is mostly used. When the punch press table moves downward, the stop baffle moves downward under the action of the nitrogen spring force. After moving a certain distance, the stop baffle contacts the product, and the inclined slide block moves downward along the slide block groove under the action of the force of the stop baffle until the lower bottom surface contacts the lower template. Then, the insert knife pushes the lower slide plate forward, and the punch starts to enter the inclined slide block to work and complete the piercing.

[0005] However, when multiple piercings are close to each other, or when the piercing is large or the material is thick, due to the large volume of the inclined slide block, the required pressure is also large, and it is difficult for the inclined slide block to return to its position by virtue of the restoring force of the spring, and there is a risk of spring breakage. Summary of the Invention

[0006] An embodiment of this application provides an inclined slide block piercing device to solve the problem that the spring force in the related art cannot adapt to the material of the workpiece to be pierced and the piercing requirements.

[0011] A stop baffle, which is placed on the inclined slide block assembly;

[0012] A first ejector rod, the top of which abuts against the stop baffle, and the bottom of which passes through the base and abuts against the first elastic mechanism;

[0013] A piercing assembly, which is movably assembled on the base;

[0020] In some embodiments, the mounting part includes a mounting table and a limiting plate, the limiting plate is connected to the bottom of the mounting table, and the elastic member is connected between the lower stripping plate and the limiting plate.

[0021] In some embodiments, the mounting table uses a sleeve, the elastic member uses a spring, the spring is sleeved on the sleeve and is limited between the lower stripping plate and the limiting plate.

[0022] In some embodiments, the inclined slider assembly includes a moving block and a fixed block, the fixed block is fixed above the base, and the moving block slides on the fixed block;

[0023] A docking port for connecting with the piercing assembly is formed on the moving block, and the bottom of the moving block abuts against the second ejector rod.

[0026] In some embodiments, at least one of the walls of the piercing assembly that abuts against the insert knife is an inclined surface.

[0027] In some embodiments, a wear-resistant plate is arranged between the piercing assembly and the insert knife.

[0028] In some embodiments, the second elastic mechanism uses a nitrogen spring.

Specific implementation manners

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0046] The embodiments of the present application provide an inclined slider puncturing device, which can solve the problem in the related art that the spring force cannot adapt to the material and puncturing requirements of the workpiece to be punctured.

[0047] See Figures 1 to 8 As shown, the present application provides an inclined slider puncturing device, including a base, a first elastic mechanism 5, a stop baffle 3, an inclined slider assembly 4, a first ejector rod 6, a second ejector rod 7, a puncture assembly 12, and an upper die base assembly 13. Among them, the inclined slider assembly 4 is arranged above the base, the stop baffle 3 is placed above the inclined slider assembly 4, and an accommodation cavity for placing the workpiece 1 is formed between the stop baffle 3 and the inclined slider assembly 4;

[0048] Specifically, a first elastic mechanism 5 is assembled under the base. The top of the second ejector rod 7 abuts against the inclined slider assembly 4, and the bottom passes through the base and abuts against the first elastic mechanism 5. The top of the first ejector rod 6 abuts against the stop plate 3, and the bottom passes through the base and abuts against the first elastic mechanism 5.

[0049] Further, as shown in Figure 1 and Figure 2 , the piercing assembly 12 is movably assembled on the base, and the upper die base assembly 13 is located above the stop plate 3. The second elastic mechanism 2 is disposed between the upper die base assembly 13 and the stop plate 3 and is used to drive the stop plate 3 to drive the inclined slider assembly 4 to move downward, and to drive the upper die base assembly 13 to press downward, so that the piercing assembly 12 is inserted into the inclined slider assembly 4 to complete the piercing of the workpiece 1.

[0050] Specifically, an upper die base assembly 13 is disposed above the stop plate 3, and a second elastic mechanism 2 is disposed between the upper die base assembly 13 and the stop plate 3. When the upper die base assembly 13 moves downward, it pushes the second elastic mechanism 2 to drive the stop plate 3 to drive the inclined slider assembly 4 to move downward. Then the upper die base assembly 13 pushes the piercing assembly 12 so that the piercing assembly 12 is inserted into the inclined slider assembly 4 to complete the piercing of the workpiece 1.

[0051] The first ejector rod 6 abuts between the stop plate 3 and the first elastic mechanism 5, and the second ejector rod 7 abuts between the inclined slider assembly 4 and the first elastic mechanism 5. When it is necessary to return the pierced workpiece 1 to its original position, the second elastic mechanism 2 jacks up the upper die base assembly 13 at its top. At the same time, the first ejector rod 6 jacks back the stop plate 3 under the action of the first elastic mechanism 5 to provide a restoring force for the reset of the upper die base assembly 13 and the stop plate 3. As the upper die base assembly 13 resets, the piercing assembly 12 is disengaged from the inclined slider assembly 4, and the second ejector rod 7 jacks up the inclined slider assembly 4 to reset under the action of the first elastic mechanism 5.

[0052] In this way, through the first ejector rod 6 and the second ejector rod 7 respectively connected to the stop plate 3 and the inclined slider assembly 4, the restoring ability of the upper die base assembly 13 and the stop plate 3 is improved, and the problem that when the piercing is large and the material is thick, the spring force cannot adapt to the material of the workpiece to be pierced and the piercing requirement can be solved.

[0053] Specifically, refer to Figure 1 and Figure 9 shown, Figure 9 are the elevation view and cross-sectional view of the workpiece. The piercing opening 101 is the place to be pierced. Since the blank holding surface of the workpiece 1 has an inclined surface, the inclined slider assembly 4 will be subjected to a lateral force when sliding. If the sliding clearance is uneven, the inclined slider will shake in the slider groove and the service life will be shortened. Therefore, as shown in Figure 4 , there are two second ejector rods 7 abutting against the inclined slider assembly 4 to apply forces on both sides simultaneously to ensure uniform force.

[0054] Preferably, there are a plurality of second ejector rods 7, which are uniformly arranged at intervals along the length direction of the workpiece 1 between the inclined slider assembly 4 and the first elastic mechanism 5.

[0055] Of course, the first ejector rod 6 also has multiple roots like the second ejector rod 7, and they are respectively arranged on both sides of the workpiece 1.

[0056] In some alternative embodiments, refer to Figure 1 and Figure 2 As shown, the first elastic mechanism 5 includes a mounting portion 502, a lower stripping plate 501 and an elastic member 503. Specifically, the mounting portion 502 is fixedly connected to the base, the lower stripping plate 501 is sleeved on the mounting portion 502, and bears the bottoms of the first ejector rod 6 and the second ejector rod 7. The elastic member 503 is assembled on the mounting portion 502, and its top is assembled on the lower stripping plate 501.

[0057] For the first elastic mechanism 5, the present application provides the following two embodiments:

[0058] Embodiment 1:

[0059] Refer to Figure 1 As shown, the mounting portion 502 includes a mounting table and a limiting plate 504. Specifically, the limiting plate 504 is arranged at one end of the mounting table far from the lower stripping plate 501. The elastic member 503 uses a spring, and the spring is sleeved on the mounting table and limited between the lower stripping plate 501 and the limiting plate 504;

[0060] When the stop plate 3 and the inclined slider assembly 4 sink together, the first ejector rod 6 and the second ejector rod 7 push the first elastic mechanism 5 to move away from the base, that is, the lower stripping plate 501 moves away from the base, and compresses the spring sleeved on the mounting portion 502; when the stop plate 3 and the inclined slider assembly 4 need to be reset, the restoring force of the spring provides an upward pushing force for the first ejector rod 6 and the second ejector rod 7. The first ejector rod 6 pushes the stop plate 3 to assist the second elastic mechanism 2 to push the upper die base assembly 13 to reset, that is, to release the insertion connection between the piercing assembly 12 and the inclined slider assembly 4.

[0061] Preferably, the spring uses a rectangular spring. Of course, the elastic member 503 can also use other elastic parts, and the purpose is to be able to be compressed and to be restored after being compressed to lift the lower stripping plate 501 to its original height.

[0062] Optionally, the mounting table uses a sleeve, and the cross-section of the sleeve is circular, which can better adapt to the inner diameter of the spring, will not scrape the spring, and prolong the service life of the spring.

[0063] Embodiment 2:

[0064] The installation part 502 includes an installation table and a limiting plate 504. Specifically, the limiting plate 504 is installed at the bottom of the installation table. The elastic member 503 uses a spring. Different from the first embodiment, the spring in this embodiment is not sleeved on the installation table, but is directly connected between the lower stripping plate 501 and the limiting plate 504;

[0065] Specifically, the length of the spring in the free state is equal to the distance between the lower stripping plate 501 and the limiting plate 504 when the lower stripping plate 501 is not pressed down. The upper end of the spring is connected to the lower stripping plate 501, or the lower end of the spring is connected to the limiting plate 504. It can also be that the upper end of the spring is connected to the lower stripping plate 501 and the lower end is connected to the limiting plate 504.

[0066] Of course, the elastic member 503 can also use other elastic parts, which will not be elaborated here.

[0067] Optionally, there are multiple installation parts 502. It should be noted that the reset speed of the stop baffle 3, the inclined slider assembly 4 and the upper die base assembly 13 can be controlled by increasing the number of elastic members 503 in the first elastic mechanism 5; it can adapt to the pressure resistance when piercing is large and can solve the problem of difficult push-back reset when the material is thick.

[0068] In some alternative embodiments, referring to Figure 2 、 Figure 7 and Figure 8 as shown, the inclined slider assembly 4 includes a moving block 402 and a fixed block 401: The fixed block 401 is fixed above the base, and the moving block 402 slides on the fixed block 401;

[0069] A docking port 403 for connecting with the piercing assembly 12 is formed on the moving block 402, and in combination with Figure 7 as shown, the bottom of the moving block 402 abuts against the second ejector rod 7.

[0070] Specifically, referring to Figure 3 as shown, the piercing assembly 12 includes a punch 121. Combining with Figure 8 as shown, Figure 8 is the position diagram of the fixed block 401 and the moving block 402 when the stop baffle 3 and the inclined slider assembly 4 sink. At this time, the punch 121 is inserted into the docking port 403 and pierces the workpiece 1 here.

[0071] Combining with Figure 7 and Figure 8 as shown, the contact surface between the moving block 402 and the fixed block 401 is an inclined surface, and the moving block 402 also undergoes a lateral displacement during the process of sliding down along this inclined surface. This can be seen from the changes in Figures 7 to 8 : Figure 7 There is a gap between the workpiece 1 in and the inclined slider assembly 4, Figure 8When the inclined slider assembly 4 is in the downward pressing state, it fits together with the workpiece 1, which also facilitates the piercing assembly 12 to penetrate the workpiece 1.

[0072] In some alternative embodiments, referring to Figures 1 to 5 As shown, the piercing assembly 12 further includes a slider 122, and the punch 121 is disposed on one side of the slider 122 close to the inclined slider assembly 4;

[0073] The upper die base assembly 13 includes an upper die base 133 and an insert knife 131. The upper die base 133 is connected to the second elastic mechanism 2. The insert knife 131 is located below the upper die base 133 and abuts against the piercing assembly 12.

[0074] Specifically, when the upper die base assembly 13 moves downward, the second elastic mechanism 2 also presses the stop plate 3 and the inclined slider assembly 4 to a specified position. During this process, the upper die base 133 pushes the insert knife 131 below it, and the insert knife 131 then pushes the piercing assembly 12 in contact with it, causing the punch 121 facing the inclined slider assembly 4 to move toward the side where the inclined slider assembly 4 is located until the punch 121 enters the moving block 402 to pierce the workpiece 1.

[0075] Optionally, at least one of the walls of the piercing assembly 12 in contact with the insert knife 131 is an inclined surface. Specifically, one surface of the piercing assembly 12 facing the insert knife 131 is an inclined surface, or one surface of the insert knife 131 facing the piercing assembly 12 is an inclined surface. Or, as Figures 1 to 2 As shown, the walls of the piercing assembly 12 in contact with the insert knife 131 are both inclined surfaces.

[0076] Preferably, a wear-resistant plate 11 is disposed between the piercing assembly 12 and the insert knife 131. The wear-resistant plate 11 can be disposed on the piercing assembly 12 or on the insert knife 131 to avoid wear between the piercing assembly 12 and the insert knife 131. Optionally, the wear-resistant plate 11 is embedded in the piercing assembly 12 or the insert knife 131 and can be replaced at any time after wear occurs.

[0077] Optionally, the upper die base assembly 13 further includes an upper backing plate 132. The upper backing plate 132 is located between the upper die base 133 and the insert knife 131 and is used to increase the height of the upper die base assembly 13 to offset the height of the second elastic mechanism 2 and the stop plate 3. Of course, the upper die base 133 and the upper backing plate 132 can also be an integral structure, which can also achieve the effect of pushing the insert knife 131 downward.

[0078] In some alternative embodiments, the second elastic mechanism 2 uses a nitrogen spring.

[0079] In some alternative embodiments, referring to Figures 1 to 5 As shown, the base includes a lower die base 8, the mounting portion 502 is fixed to the bottom of the lower die base 8, and the lower stripping plate 501 abuts against the lower part of the lower die base 8;

[0080] Optionally, a bottom plate 9 is connected below the lower die base 8 through support feet 10, and the bottom plate 9 is placed on a machine tool or a tabletop.
