Description

Technical Field

[0001] This application relates to the technical field of automotive front bumper beam support plates, specifically a drawing die for automotive front bumper beam support plates. Background Technology

[0002] The front bumper support plate is a crucial component of the front structure of a car. Its primary function is to absorb and disperse impact forces during a collision, protecting vital components such as the engine, transmission, and fuel tank from damage. The working principle of a drawing die is based on using a punch and die to press the sheet metal. Under the action of a press, the punch pushes the sheet metal towards the die, while the blank holder controls the material feed rate, ensuring uniform material entry into the die cavity. During this process, certain portions of the sheet metal are stretched or drawn to form the desired part shape. Drawing dies have wide applications in automotive manufacturing. For example, in the production of the front bumper support plate, by designing a drawing die with asynchronous blank holders, the combined action of the upper and lower blank holders ensures sufficient forming during the sheet metal flow, solving the stamping process problem of cracking and wrinkling coexisting in the drawing of complex-shaped internal covering aluminum alloy products with small curvature.

[0003] After the front bumper beam support plate is processed, it will remain inside the groove of the lower mold. At this point, personnel need to remove the support plate from the lower mold for further processing. During removal, the support plate may become too tightly fitted to the inner wall of the groove. Therefore, before further processing, lubricating grease needs to be injected into the groove to improve demolding efficiency. However, manually injecting lubricating grease can be difficult due to limitations in precise control over the application location and amount. Insufficient grease may cause demolding difficulties, while excessive grease can form a thick film on the mold surface, affecting the surface quality of the product and potentially causing accumulation and sagging. Utility Model Content

[0004] The purpose of this application is to provide a drawing die for a front bumper beam support plate of an automobile, so as to solve the problem mentioned in the background art that when the lubricating grease is injected manually, it is difficult for the operator to accurately control the precise position and amount of the grease. Too little lubricating grease may lead to demolding difficulties, while too much lubricating grease will form a thick film on the mold surface, affecting the surface quality of the product, and may also cause problems such as accumulation and sagging.

[0005] To achieve the above objectives, this application provides the following technical solution: a drawing die for a front bumper beam support plate of an automobile, comprising: a fixed frame, a lower die, a lifting upper die, an opening mechanism, and a conveying mechanism. The main body of the drawing die includes a fixed frame, a lower die disposed at the bottom of the fixed frame, and a lifting upper die disposed at the top of the fixed frame. The inner wall of the groove of the lower die has a horizontal through hole, and a vertical hole is vertically connected inside the horizontal through hole of the lower die. The opening mechanism is disposed in the horizontal through hole of the lower die. The opening mechanism includes an insert rod slidably connected in the horizontal through hole of the lower die, a fixed plate welded to one end of the insert rod, positioning blocks disposed on both sides of the bottom of the lower die, a connecting rod slidably connected inside the positioning blocks, one end of the connecting rod welded to the outer wall of the fixed plate, a trapezoidal block welded to the other end of the connecting rod, a spring sleeved on the connecting rod, a large air cylinder disposed at the center of the bottom of the lower die, and a conical block fixed to the output end of the large air cylinder. The conveying mechanism is disposed in the vertical hole of the lower die.

[0006] By adopting the above technical solution, the lubricating grease can be automatically delivered in equal and specified amounts to the inner wall of the groove of the lower mold.

[0007] Preferably, the lifting upper mold consists of a small cylinder fixed to the top of the fixed frame and an upper mold body fixed to the output end of the small cylinder.

[0008] By adopting the above technical solution, the upper mold body can be driven by the push of the small cylinder to squeeze and push the raw material into the interior of the lower mold.

[0009] Preferably, the conveying mechanism includes a first connecting pipe with one end fixed in a vertical hole in the lower mold, and the first connecting pipe is distributed at both ends above the lower mold.

[0010] By adopting the above technical solution, when lubrication of the lower mold is required, lubricating grease can be quickly delivered to the inner wall of the groove of the lower mold.

[0011] Preferably, the conveying mechanism further includes a second connecting pipe connected to the other end of the first connecting pipe.

[0012] By adopting the above technical solution, the subsequent delivery of lubricating grease can be achieved through pipeline connection.

[0013] Preferably, the conveying mechanism further includes a storage tank disposed on the second connecting pipe, wherein a water pump is disposed inside the storage tank and the water pump inside the storage tank is connected to the second connecting pipe.

[0014] By adopting the above technical solution, the lubricating grease in the storage tank can be delivered through the connection of a water pump.

[0015] Preferably, the inner diameter of the first connecting pipe above the lower mold near the storage box is smaller than the inner diameter of the first connecting pipe above the lower mold away from the storage box.

[0016] By adopting the above technical solution, the consistency of lubricating grease can be maintained during the transportation process.

[0017] In summary, this application offers the following advantages: The present invention includes an opening mechanism and a conveying mechanism. The opening mechanism allows the holes at various points on the inner wall of the lower mold to open, precisely delivering lubricating grease to designated locations within the lower mold's groove during opening. During closing, the lubricating grease remains flush with the inner wall of the lower mold's groove, thus not affecting the processing of the workpiece. The conveying mechanism ensures that the lubricating grease is applied to the designated locations on the inner wall of the lower mold's groove each time, and the automated control during application avoids the problems of excessive or insufficient application caused by traditional manual application.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The following is in conjunction with the appendix Figure 1-4The embodiments of this application will be described in further detail.

[0025] Example 1

[0026] Please see Figures 1-4 This embodiment provides a technical solution: a drawing forming mold for a front anti-collision beam support plate of an automobile, including: a fixed frame 1, a lower mold 2, a lifting upper mold 3, an opening mechanism 4, and a conveying mechanism 5;

[0027] The main body of the drawing die includes a fixed frame 1, a lower die 2 set at the bottom of the fixed frame 1, and a lifting upper die 3 set at the top of the fixed frame 1. The inner wall of the groove of the lower die 2 is provided with a horizontal through hole, and a vertical hole is vertically connected inside the horizontal through hole of the lower die 2. The lifting upper die 3 is composed of a small cylinder fixed at the top of the fixed frame 1 and an upper die body fixed at the output end of the small cylinder. The above is the prior art, and will not be described in detail below.

[0028] The opening mechanism 4 is set in the horizontal through hole of the lower mold 2. The opening mechanism 4 includes a plug rod 401 slidably connected in the horizontal through hole of the lower mold 2, a fixing plate 402 welded to one end of the plug rod 401, positioning blocks 403 set on both sides of the bottom of the lower mold 2, a connecting rod 404 slidably connected inside the positioning block 403, one end of the connecting rod 404 welded to the outer wall of the fixing plate 402, a trapezoidal block 405 welded to the other end of the connecting rod 404, a spring 406 sleeved on the connecting rod 404, a large air cylinder 407 set in the middle of the bottom of the lower mold 2, a conical block 408 fixed on the output end of the large air cylinder 407, and a conveying mechanism 5 set in the vertical hole of the lower mold 2.

[0029] When it is necessary to inject lubricating grease into the inner wall of the groove of the lower mold 2, the atmospheric cylinder 407 is started to work, thereby driving the conical block 408 on the output end to move. During the movement of the conical block 408, it can push the trapezoidal block 405 to produce displacement. At this time, the trapezoidal block 405 is connected to the fixed plate 402 through the connecting rod 404, so that the connecting rod 404 located inside the positioning block 403 maintains a stable sliding displacement. During the movement, the fixed plate 402 is no longer pulled by the elastic force of the spring 406, so that the insertion rod 401 of the fixed plate 402 moves synchronously, thus preventing the vertical hole connected through the horizontal through hole of the lower mold 2 from being blocked.

[0030] The conveying mechanism 5 can deliver lubricating grease to the inner wall of the lower mold 2. The raw material is placed above the lower mold 2. By activating the lifting upper mold 3 at the top of the fixed frame 1, the vertical movement of the lifting upper mold 3 will squeeze the raw material into the groove of the lower mold 2, thereby realizing the processing of the automotive front anti-collision beam support plate.

[0031] Example 2

[0032] Please see Figures 1-4 This embodiment provides a technical solution: a drawing forming mold for a front anti-collision beam support plate of an automobile, including: a first connecting pipe 501, a second connecting pipe 502 and a storage box 503;

[0033] The conveying mechanism 5 includes a first connecting pipe 501 with one end fixed in the vertical hole of the lower mold 2, the first connecting pipe 501 being distributed at both ends above the lower mold 2, a second connecting pipe 502 connected to the other end of the first connecting pipe 501, a storage box 503 disposed on the second connecting pipe 502, a water pump being disposed inside the storage box 503, and the water pump inside the storage box 503 being connected to the second connecting pipe 502, the inner diameter of the first connecting pipe 501 above the lower mold 2 near the storage box 503 being smaller than the inner diameter of the first connecting pipe 501 above the lower mold 2 away from the storage box 503.

[0034] After being pumped from the storage tank 503, the lubricating grease first flows through the first connecting pipe 501 closest to the storage tank 503. The smaller inner diameter of this first connecting pipe increases the flow resistance of the lubricating grease. Then, it flows to the first connecting pipe 501 furthest from the storage tank 503, where the larger inner diameter reduces the flow resistance. This process prevents excessive lubricating grease from being sprayed out of the first connecting pipe 501 near the storage tank 503 due to excessive pressure, while also preventing insufficient lubricating grease from being discharged from the first connecting pipe 501 furthest from the storage tank 503 due to insufficient pressure. It also avoids uneven distribution of lubricating grease due to distance differences, ensuring a consistent amount of lubricating grease.

[0035] Start the water pump inside the storage tank 503. At this time, the water pump inside the storage tank 503 will transport the lubricating grease to the inside of the first connecting pipe 501 through the second connecting pipe 502. Since the first connecting pipe 501 is connected to the vertical hole of the lower mold 2, the lubricating grease is transported to the designated position on the inner wall of the lower mold 2.

[0036] The implementation principle of the drawing die for the front bumper beam support plate of an automobile in this application is as follows:

[0037] First, when it is necessary to inject lubricating grease into the inner wall of the groove of the lower mold 2, the large air cylinder 407 is started to work, thereby driving the conical block 408 on the output end to move. During the movement of the conical block 408, it can push the trapezoidal block 405 to produce displacement. At this time, the trapezoidal block 405 is connected to the fixed plate 402 through the connecting rod 404, so that the connecting rod 404 located inside the positioning block 403 maintains a stable sliding displacement. During the movement, the fixed plate 402 is no longer pulled by the elastic force of the spring 406, so that the insertion rod 401 of the fixed plate 402 moves synchronously, thus preventing the vertical hole connected through the horizontal through hole of the lower mold 2 from being blocked.

[0038] Next, the water pump inside the storage tank 503 is started. At this time, the water pump inside the storage tank 503 delivers the lubricating grease to the inside of the first connecting pipe 501 through the second connecting pipe 502. Since the first connecting pipe 501 is connected to the vertical hole of the lower mold 2, the lubricating grease is delivered to the designated position on the inner wall of the lower mold 2.

[0039] Finally, the raw material is placed above the lower mold 2. By activating the lifting upper mold 3 at the top of the fixed frame 1, the vertical movement of the lifting upper mold 3 squeezes the raw material into the groove of the lower mold 2, thereby realizing the processing of the automotive front anti-collision beam support plate.

[0040] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
