Description

Technical Field

[0001] The present application relates to the field of stamping die technology, and in particular to a stamping die for automobile parts. Background Art

[0002] The door sill is a device located just below the car door. Its main function is to beautify and protect the car paint. In addition, the door sill can effectively protect the parts of the car body that are prone to wear and tear, especially on vehicles with higher bodies. The welcome pedal can provide additional safety when getting on and off the car, avoiding the inconvenience and safety hazards caused by the high body.

[0003] In the prior art, when processing the inner panel of the automobile threshold, it is often necessary to perform multiple processes and bend the inner panel of the automobile threshold multiple times during the process. Although this can ensure processing accuracy to a certain extent, it cannot ensure work efficiency due to the large number of processing processes. In addition, since the inner panel of the threshold needs to be shifted back and forth between different processes, the error rate in the processing process is also increased. Utility Model Content

[0004] In order to simplify the processing procedures of the inner panel of the automobile threshold and ensure that the inner panel of the automobile threshold can be integrally formed while shortening the construction period, the present application provides an automobile part stamping die.

[0005] The present application provides an automobile parts stamping die adopting the following technical solution:

[0006] A stamping die for automobile parts is used for integrally forming the inner panel of an automobile door sill, comprising a pad, a base fixed on the pad, and a mounting seat installed on the base, the mounting seat comprising a plurality of mounting blocks arranged in sequence along the length direction of the base, the upper ends of the mounting blocks are adapted to the shape of the inner panel, and the upper ends of the plurality of mounting blocks jointly form a groove structure, a stamping plate for stamping the inner panel is provided on the side of the mounting seat away from the base, a stamping block matching the shape of the inner panel is installed on the side of the stamping plate close to the mounting seat, the stamping block is provided with a plurality of stamping holes penetrating along the length direction on the side away from the inner panel, and positioning blocks are installed at the positions of the plurality of stamping holes, and a stamping pin is penetratingly provided on the stamping plate, the bottom of which abuts against the side of the positioning block away from the inner panel.

[0007] By adopting the above technical solution, the plate to be processed is placed on the mounting base composed of several mounting blocks. Subsequently, the stamping block at the bottom of the stamping plate performs stamping operations on the plate, and at the same time, the punching pins arranged inside the positioning blocks punch holes in the formed inner plate. The inner plate of the car sill can be integrally stamped and formed, and punching of the inner plate can be achieved during the stamping process, simplifying the operation steps and die structure of the inner plate stamping and forming, improving the overall economic applicability of the stamping die, reducing the probability of errors in plate processing, and increasing the qualification rate of the inner plate finished products.

[0008] Optionally, rubber cushion blocks for buffering the impact caused by the stamping block are arranged on one side of several of the mounting blocks close to the base, and the rubber cushion blocks are fixedly embedded on one side of the mounting blocks close to the base.

[0009] By adopting the above technical solution, when the stamping block stamps the inner plate, the rubber cushion blocks arranged at the bottom of the mounting blocks can prevent the inner plate and the mounting blocks from being subjected to excessive impact force, ensuring that the parts are not easily damaged and making the stability of the die better during the stamping process.

[0010] Optionally, a jacking mechanism for preventing the inner plate from adhering to the mounting base is provided on the mounting base, including two elastic blocks symmetrically and movably penetrating along the length direction on one side of the mounting base close to the inner plate, a buffer plate embedded inside the elastic blocks, and a jacking pin with two ends respectively abutted against the buffer plate and one side of the inner plate close to the mounting block.

[0011] By adopting the above technical solution, it can prevent the situation where when the stamping pressure is too high, the inner plate and the mounting base are completely in close contact, resulting in the inability of the staff to smoothly remove the inner plate. After the inner plate is stamped and the stamping block is separated from the inner plate, the elastic blocks and the jacking pins inside the elastic blocks will jack up the inner plate. The structure is simple and will not affect the stamping process of the inner plate, improving the convenience of die operation.

[0012] Optionally, one end of the jacking pin close to the inner plate is of a hemispherical structure.

[0013] By adopting the above technical solution, it can be avoided that during stamping, the contact area between the jacking pin and the inner plate is too large, resulting in the impact force on the jacking pin exceeding its bearing limit and playing a protective role for the jacking mechanism.

[0014] Optionally, a number of hollow-out grooves for reducing the weights of the base and the stamping plate are provided on the sides of the base and the stamping plate away from each other, and the number of the hollow-out grooves is distributed in an array.

[0015] By adopting the above technical solutions, while ensuring the structural strength of the base and the stamping plate, the overall mass and material consumption of the base and the stamping plate can be reduced, thereby saving the manufacturing cost of the mold and the energy consumption during the stamping of the inner plate by the mold, and improving the economic practicality of the mold.

[0016] Optionally, a plurality of waist-shaped holes are symmetrically formed in the two opposite sides perpendicular to the length direction of the stamping block along the length direction. The plurality of waist-shaped holes are all arranged along the stamping direction, and a limiting pin is slidably connected in each of the plurality of waist-shaped holes. One end of the limiting pin away from the waist-shaped hole extends out of the side surface of the mounting block along the width direction. A connecting plate is sleeved on the limiting pin, and the connecting plate is detachably connected to the stamping plate.

[0017] By adopting the above technical solutions, the position of the stamping block on the stamping plate can be adjusted, avoiding the formation of a rigid connection structure between the stamping plate and the stamping block, resulting in excessive internal stress inside the two during the stamping process, and finally causing cracking on the surfaces of the stamping block and the stamping plate, effectively improving the service life of the parts.

[0018] Optionally, a limiting plate for preventing the stamping pin from punching out of the stamping plate is provided at the top of the stamping pin, and the limiting plate is detachably connected to the stamping plate.

[0019] By adopting the above technical solutions, the limiting plate can prevent the stamping pin from separating from the mounting block when the mold is unloaded, resulting in the abnormal operation of the jacking mechanism.

[0020] Optionally, a plurality of limiting blocks for limiting the inner plate are arranged on the base along the length direction. The plurality of limiting blocks are symmetrically installed on both sides of the inner plate on the base, and the sides of the plurality of limiting blocks close to each other are in close contact with the side edge of the inner plate.

[0021] By adopting the above technical solutions, a plurality of limiting blocks on both sides of the inner plate can clamp and limit the inner plate when the inner plate is on the mounting block, avoiding the displacement of the inner plate during stamping and resulting in errors in the stamping result.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. In the present application, a plurality of mounting seats composed of mounting blocks are provided to place the inner plate, and the shapes of the inner sides of the mounting seats and the stamping blocks are adapted to the shape of the inner plate, so that the stamping operation of integral forming of the inner plate can be carried out, improving the working efficiency of the stamping of the inner door sill and simplifying the stamping process;

[0024] 2. In the present application, by providing a jacking mechanism on the mounting block, the inner plate can be smoothly taken out after being stamped, making the production process more smooth and improving the production efficiency;

[0025] 3. The present application can punch the inner panel during the stamping process of the inner panel, improving the working ability of the mold and the forming efficiency of the inner panel. Description of the Drawings

Detailed Description of the Embodiment

[0036] The following will further describe the present application in detail with reference to the attached Figures 1-9 drawings.

[0037] The embodiment of the present application discloses a stamping die for an automotive part.

[0038] Referring to Figure 1 andFigure 2 and Figure 3 , a stamping die for automobile parts, which is used for the integral forming processing operation of the inner panel 1 of the automobile sill. Specifically, it includes a backing plate 2 placed on the ground, a base 3 fixedly installed on the side of the backing plate 2 away from the ground, and a mounting seat 4 fixedly installed on the side of the base 3 away from the backing plate 2. The mounting seat 4 is composed of a plurality of mounting blocks 41 arranged side by side in sequence, and the side of the mounting seat 4 away from the base 3 is a groove-shaped structure adapted to the shape of the side of the formed inner panel 1.

[0039] The purpose of setting the mounting seat 4 composed of a plurality of mounting blocks 41 here is to make the impact force acting on the mounting seat 4 during the stamping process be evenly distributed to each mounting block 41, so as to avoid damage to the mounting seat 4 caused by excessive local stress.

[0040] Refer to Figure 2 and Figure 5 , further, a stamping plate 5 for stamping and forming the inner panel 1 is arranged at intervals above the side of the mounting seat 4 away from the base 3. A stamping block 6 adapted to the shape of the side of the inner panel 1 away from the mounting seat 4 is detachably installed on the side of the stamping plate 5 close to the mounting seat 4. A plurality of stamping holes 61 are longitudinally penetrated through the stamping block 6, and positioning blocks 62 are installed at the positions of the stamping holes 61 on the side of the stamping block 6 close to the stamping plate 5. A stamping pin 63 for punching the inner panel 1 is movably inserted through the positioning block 62. One end of the positioning block 62 away from the stamping block 6 extends out of the upper side of the stamping plate 5, so as to facilitate the installation of the stamping pin 63 and the driving device to drive the stamping pin 63 to work. A limiting plate 51 for preventing the stamping pin 63 from punching out of the stamping plate 5 is arranged at the top of the stamping pin 63, and the limiting plate 51 is detachably connected to the stamping plate 5.

[0041] Among them, a plurality of hollow grooves are arranged in an array on the sides of the base 3 and the stamping plate 5 away from each other, so as to reduce the mass of the base 3 and the stamping plate 5 on the premise of ensuring their structural strength, reduce the load energy consumption of the whole die, and improve the economic applicability of the die.

[0042] It should be noted that since the hollow groove design is mainly to dig holes in the base 3 and the stamping plate 5 to achieve the purpose of reducing the mass of the base 3 and the stamping plate 5, there are no special requirements for the specific shape and structure of the hollow grooves, so they are not shown in the drawings of this embodiment.

[0043] Refer to Figure 4 and Figure 6 , furthermore, a rubber cushion block 411 for buffering the stamping operation of the stamping block 6 is arranged at the bottom of the mounting block 41. The rubber cushion block 411 is in a waist-shaped structure, and the rubber cushion block 411 is embedded in the bottom of the mounting block 41.

[0044] Preferably, two rubber cushion blocks 411 are embedded at the bottoms of the two mounting blocks 41 located at both ends of the mounting seat 4 in the length direction, so as to provide sufficient buffering and also provide frictional force to prevent the several mounting blocks 41 from sliding along the length direction of the mounting seat 4.

[0045] Refer to Figure 4 and Figure 6 , a number of limiting blocks 31 for internally clamping and limiting are provided on the base 3. The limiting blocks 31 are detachably connected to the base 3, and the several limiting blocks 31 are regularly distributed on both sides of the inner plate 1 on the mounting seat 4 and are in close contact with the side surface of the inner plate 1.

[0046] Refer to Figure 2 , Figure 7 and Figure 8 , a jacking mechanism 7 for preventing the inner plate 1 from adhering to the top surface of the mounting seat 4 after stamping is provided on the mounting seat 4. The jacking mechanism 7 specifically includes two elastic blocks 71 symmetrically and movably arranged on one side of the mounting seat 4 close to the inner plate 1 along the length direction of the mounting seat 4, a buffer plate 72 embedded inside the elastic blocks 71, and a jacking pin 73 with its bottom abutting against the buffer plate 72 and its top extending out of the surface of the mounting seat 4. The top of the jacking pin 73 extends out of the top of the mounting seat 4 and abuts against the bottom surface of the inner plate 1 close to the mounting seat 4.

[0047] When the inner plate 1 is stamped, the jacking pin 73 is pressed into the elastic block 71, and at the same time, the upper end surface of the elastic block 71 is compressed to be flush with the upper end surface of the mounting seat 4. After that, when the stamping of the inner plate 1 is completed, the jacking pin 73 and the elastic block 71 will jack up the inner plate 1.

[0048] It should be noted that in this embodiment, the end of the jacking pin 73 in contact with the inner plate 1 is of a hemispherical structure, so that the contact area between the jacking pin 73 and the inner plate 1 will not be too large, ensuring that the impact force received by the jacking pin 73 will not damage the jacking pin 73.

[0049] Refer to Figure 2 and Figure 9 , a number of waist-shaped holes 64 are symmetrically arranged along the length direction on the two opposite sides perpendicular to the length direction of the stamping block 6, and a limiting pin 65 fixedly connected to the stamping block 6 is fixedly connected inside the waist-shaped holes 64. Specifically, the waist-shaped holes 64 are arranged along the stamping direction, and the position of the limiting pin 65 in the waist-shaped holes 64 can be adjusted by rotation.

[0050] The end of the limiting pin 65 extends out of one side of the mounting block 41 in the width direction, that is, the distance between the mutually remote end faces of the two limiting pins 65 in the waist-shaped holes 64 on the two opposite sides of the stamping block 6 is greater than the width of the mounting block 41, so that the stamping block 6 will not collide with the mounting block 41 and protect the structural integrity of both.

[0051] A connecting plate 52 is sleeved on the limit pin 65, and the connecting plate 52 is fixedly connected to the stamping plate 5, which facilitates the disassembly and replacement of the stamping block 6.

[0052] The implementation principle of a stamping die for automotive parts in an embodiment of the present application is as follows:

[0053] Place the inner plate 1 on the mounting seat 4 composed of a number of mounting blocks 41, and then drive the stamping block 6 by the stamping plate 5 to stamp the inner plate 1 to form it integrally. After that, drive the stamping pin 63 located on the stamping block 6 by the driving device to punch holes in the already formed inner plate 1.

[0054] After stamping is completed, the stamping plate 5 drives the stamping block 6 to rise, and the elastic block 71 and the ejecting pin 73 located on the mounting block 41 eject the inner plate 1 under the action of elastic force, enabling the staff to smoothly take out the inner plate 1 and realizing the entire process of stamping the inner plate 1 completely.

[0055] The above are all the preferred embodiments of the present application. Without restricting the protection scope of the present application based on this, therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
