Description

Technical Field

[0001] This utility model belongs to the field of stamping technology for automotive seat belt mounting plates, specifically relating to a stamping die for an automotive seat belt mounting plate. Background Technology

[0002] The car seat belt mounting plate is a key component in the car body structure used to fix the seat belt assembly. It is usually made of stamped metal sheet and is generally installed on the car body frame near the seat, such as under the seat, B-pillar or C-pillar. Its main function is to provide a stable mounting base for the seat belt retractor, buckle and other components, to ensure that the seat belt can effectively restrain the body of the driver and passengers in the event of a collision or sudden braking, and reduce the injury caused by inertia.

[0003] In the stamping production process of automotive seat belt mounting plates, the stamping operation of the mounting plate is usually achieved by merging the upper and lower dies. Although traditional stamping dies can complete the basic stamping operation, there are many problems in practical applications: Since multiple mounting plates are usually stamped from a single sheet, after stamping one mounting plate, the sheet needs to be moved for the next stamping. During this process, due to the lack of stable guiding and limiting structures, the sheet is very prone to warping at both ends during stamping, which leads to positional deviation when the sheet enters the stamping area, seriously affecting stamping accuracy and product quality. Utility Model Content

[0004] In view of this, the present invention provides a stamping die for an automotive seat belt mounting plate, which can prevent the two ends of the plate from warping by guiding and limiting, and avoid positional deviation of the plate when entering the stamping area, thus affecting stamping accuracy and product quality.

[0005] To solve the above-mentioned technical problems, this utility model provides a stamping die for an automotive seat belt mounting plate, including a worktable and a stamping unit for stamping the mounting plate. Both ends of the worktable have guide units, each guide unit including fixed plates symmetrically arranged on both sides of the upper end of the worktable. Guide rollers are rotatably connected to the upper ends of the two fixed plates on the same side. A rectangular rod is provided at the lower end of each of the two fixed plates on the same side, and a sliding plate is slidably connected to each rectangular rod. The sliding plates are movably fitted onto the outer arc surface of the adjacent guide rollers on the same side. A bidirectional lead screw is rotatably connected to the lower end of each of the two fixed plates on the same side. The two ends of the bidirectional lead screw are threadedly connected to screw holes provided on the adjacent sliding plates on the same side. A pressing component is provided at the upper end of each sliding plate, ensuring that the sheet metal smoothly enters the stamping area. Throughout the process, the guiding and limiting mechanisms prevent the ends of the sheet metal from warping, avoiding positional deviation when the sheet metal enters the stamping area, which would affect stamping accuracy and product quality.

[0006] The pressing assembly includes slide grooves respectively set on the upper end of the sliding plate. Each slide groove has a slider slidably connected in it and a threaded rod rotatably connected in it. The threaded rods are threadedly connected to the sliders located in the same slide groove, which serves as a pressing limit.

[0007] The pressing assembly also includes several rotating wheels respectively disposed on the lower inner side of the slider, which reduces the coefficient of friction against the mounting plate.

[0008] It also includes an oiling assembly, which includes an oil cylinder rotatably connected to the inside of the slider. Each oil cylinder has a sealing plug movably installed in the opening at the inner end. Each sealing plug has a sponge sleeve movably fitted on its outer arc surface. The inner arc surface of the sponge sleeve is provided with several capillary ropes. Each capillary rope passes through the cylinder wall of the oil cylinder and extends into the interior, thus achieving the function of uniformly applying oil.

[0009] The stamping unit includes a bottom die set on the upper part of the worktable, a support frame at the upper end of the worktable, an upper die slidably connected between the four rods of the support frame, and a hydraulic cylinder at the upper end of the support frame. The telescopic end of the hydraulic cylinder is fixedly connected to the upper end of the upper die, thus achieving the purpose of rapid stamping.

[0010] The top of the guide rollers is flush with the top of the bottom die, ensuring that the sheet metal enters the stamping area smoothly.

[0011] The two oil cylinders on the same side are staggered to ensure even oil application.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. Based on the width of the car seat belt mounting plate, rotate the double-ended lead screw sequentially. When the double-ended lead screw rotates, the sliding plates connected to its two ends by threads slide along the rectangular rod, thereby adjusting the distance between the two sliding plates located on the same guide roller to accommodate plates of different widths. At the same time, rotate the threaded rod to drive the slider to slide along the slide groove, adjusting the relative position of the slider until several rollers at the lower inner side of the slider contact the plate. This, in conjunction with the guide roller, achieves stable conveying of the plate and prevents its ends from tilting up. The uppermost end of the guide roller is flush with the uppermost end of the bottom die to ensure that the plate enters the stamping area smoothly. The entire process prevents the ends of the plate from tilting up through guidance and limiting, avoiding positional deviation of the plate when entering the stamping area, which would affect stamping accuracy and product quality.

[0014] 2. The lubricating oil in the oil cylinder penetrates into the sponge sleeve through the capillary rope. The sponge sleeve contacts the plate and applies oil to the plate surface. The two oil cylinders on the same side are staggered to ensure uniform oil application and form an oil film on the plate surface. Applying oil reduces friction and wear during die stamping.

[0015] 3. The sheet metal is conveyed to the stamping unit. The hydraulic cylinder at the upper end of the support frame drives the upper die to slide down along the rod of the support frame, and cooperates with the bottom die at the upper end of the worktable to complete the stamping of the sheet metal.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a stamping die for an automotive seatbelt mounting plate, such as... Figure 1-4The worktable 100 includes a stamping unit for stamping mounting plates. Both ends of the worktable 100 have guide units. Each guide unit includes fixed plates 200 symmetrically arranged on both sides of the upper end of the worktable 100. Guide rollers 201 are rotatably connected to the upper ends of the two fixed plates 200 on the same side. Rectangular rods 202 are provided at the lower ends of the two fixed plates 200 on the same side. Sliding plates 203 are slidably connected to the rectangular rods 202. The sliding plates 203 are movably fitted onto the outer arc surfaces of the adjacent guide rollers 201 on the same side. A bidirectional lead screw 2 is rotatably connected to the lower ends of the two fixed plates 200 on the same side. 04. The two ends of the bidirectional lead screw 204 are respectively threaded to the screw holes provided on the adjacent sliding plate 203 on the same side. The upper end of the sliding plate 203 is provided with a pressing component. The uppermost end of the guide roller 201 is flush with the uppermost end of the bottom mold 500. The pressing component includes a slide groove 300 respectively provided on the upper end of the sliding plate 203. A slider 301 is slidably connected in the slide groove 300. A threaded rod 302 is rotatably connected in the slide groove 300. The threaded rod 302 is threadedly connected to the slider 301 located in the same slide groove 300. The pressing component also includes a number of rotating wheels 303 respectively provided on the lower inner side of the slider 301.

[0023] First, based on the width of the car seat belt mounting plate, the double-acting screw 204 is rotated sequentially. When the double-acting screw 204 rotates, the sliding plates 203 connected to its two ends slide along the rectangular rod 202, thereby adjusting the distance between the two sliding plates 203 located on the same guide roller 201 to accommodate plates of different widths. At the same time, the threaded rod 302 is rotated, thereby driving the slider 301 to slide along the groove 300 and adjusting the relative position of the slider 301 until several rotating wheels 303 at the lower inner side of the slider 301 contact the plate. This, in conjunction with the guide roller 201, achieves stable conveying of the plate and prevents its ends from tilting up. The uppermost end of the guide roller 201 is flush with the uppermost end of the bottom mold 500 to ensure that the plate enters the stamping area smoothly. The entire process prevents the ends of the plate from tilting up through guidance and limiting, and reduces friction and wear during mold stamping by applying oil.

[0024] like Figure 1-4As shown, it also includes an oiling assembly, which includes oil cylinders 400 rotatably connected to the inner side of the slider 301. Each oil cylinder 400 has a sealing plug 401 movably disposed in the opening at its inner end. Each sealing plug 401 has a sponge sleeve 402 movably fitted on its outer arc surface. The inner arc surface of the sponge sleeve 402 is provided with several capillary ropes 403. Each capillary rope 403 passes through the cylinder wall of the oil cylinder 400 and extends into the interior. The two oil cylinders 400 on the same side are staggered left and right. During the conveying of the sheet metal, the oiling assembly starts to work. The lubricating oil in the oil cylinder 400 penetrates into the sponge sleeve 402 through the capillary ropes 403. The sponge sleeve 402 contacts the sheet metal and applies oil to the surface of the sheet metal. The staggered arrangement of the two oil cylinders 400 on the same side ensures uniform oiling and forms an oil film on the surface of the sheet metal.

[0025] like Figure 1-3 As shown, the stamping unit includes a bottom die 500 disposed on the upper end of the worktable 100. A support frame 501 is provided at the upper end of the worktable 100. An upper die 502 is slidably connected between the four rods of the support frame 501. A hydraulic cylinder 503 is provided at the upper end of the support frame 501. The telescopic end of the hydraulic cylinder 503 is fixedly connected to the upper end of the upper die 502. When the sheet metal is transported to the stamping unit, the hydraulic cylinder 503 at the upper end of the support frame 501 drives the upper die 502 to slide downward along the rods of the support frame 501, cooperating with the bottom die 500 at the upper end of the worktable 100 to complete the stamping of the sheet metal.

[0026] The working principle of the stamping die for an automotive seatbelt mounting plate provided by this utility model is as follows: First, according to the width of the automotive seatbelt mounting plate, the double-acting screw 204 is rotated sequentially. When the double-acting screw 204 rotates, the sliding plates 203 connected to its two ends by threads slide along the rectangular rod 202, thereby adjusting the distance between the two sliding plates 203 located on the same guide roller 201 to accommodate plates of different widths. At the same time, the threaded rod 302 is rotated, thereby driving the slider 301 to slide along the slide groove 300, adjusting the relative position of the slider 301 until several rotating wheels 303 at the lower inner end of the slider 301 contact the plate. This, together with the guide roller 201, achieves stable conveying of the plate, preventing the two ends from warping up when moving the plate for the next stamping after stamping one mounting plate. During the sheet material conveying process, the oiling assembly starts working. The lubricating oil in the oil cylinder 400 permeates into the sponge sleeve 402 through the capillary rope 403. The sponge sleeve 402 contacts the sheet material, applying oil to the surface of the sheet material. The two oil cylinders 400 on the same side are staggered to ensure uniform oiling, forming an oil film on the surface of the sheet material. Subsequently, the sheet material is conveyed to the stamping unit. The hydraulic cylinder 503 at the upper end of the support frame 501 drives the upper die 502 to slide downward along the rod of the support frame 501, cooperating with the bottom die 500 at the upper end of the worktable 100 to complete the stamping of the sheet material. The uppermost end of the guide roller 201 is flush with the uppermost end of the bottom die 500, ensuring that the sheet material enters the stamping area smoothly. Throughout the process, the guide and limit functions prevent the two ends of the sheet material from warping, and the oiling reduces friction and wear during die stamping.

[0027] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
