Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stamping dies, and more specifically to a continuous forming die for stamping an energy-absorbing box. Background Technology
[0002] Energy-absorbing boxes are important energy-absorbing devices in automotive safety systems. They are installed between the crossbeams and the longitudinal beams of the vehicle frame, serving as a safety protection system. As a thin-walled metal component, the energy-absorbing box is prone to wrinkling and deformation during a collision. In low-speed collisions, it effectively absorbs collision energy and minimizes the impact force on the vehicle body. The energy-absorbing box improves the passive safety of the vehicle and reduces the repair costs caused by a collision.
[0003] Energy-absorbing boxes are typically manufactured using a stamping process. The strip is first trimmed by a trimming stamping machine, then shaped by a forming stamping machine, and finally cut off by a cutting stamping machine to complete the process. However, this method requires three machines—the trimming stamping machine, the forming stamping machine, and the cutting stamping machine—to work together. This is not only costly but also requires frequent adjustments to ensure coordination, making the operation cumbersome. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the processing of energy-absorbing boxes in the prior art requires the coordinated operation of three machines: a trimming stamping machine, a forming stamping machine, and a cutting stamping machine. This not only results in high costs but also cumbersome operation due to the need for frequent adjustments to ensure coordination.
[0005] To address the aforementioned problems, this utility model provides a continuous forming die for an energy-absorbing box, comprising a fixed die table and a movable die table that is vertically and flexibly positioned above the fixed die table. The fixed die table has a trimming station, a forming station, and a cutting station arranged from front to back. The trimming station includes a trimming table with a trimming groove on its upper side. The forming station includes a forming table with a forming surface on its upper side. The cutting station includes a cutting table and a blanking hole on the upper side of the fixed die table. The cutting table is adjacent to the blanking hole, and a cutting support is provided on the side of the cutting table closest to the blanking hole. The movable die table has a trimming pressure head corresponding to the trimming station, a forming pressure head corresponding to the forming station, and a cutting pressure head corresponding to the cutting station.
[0006] Compared with existing technologies, the above solution integrates the trimming station, forming station, and cutting station on the same fixed mold table. When the strip is conveyed from front to back, the trimming head will cooperate with the trimming station to trim the corresponding position of the strip, the forming head will cooperate with the forming station to form the corresponding position of the strip, and the cutting head will cooperate with the cutting station to cut the corresponding position of the strip. That is, each time the moving mold table punches, the three positions on the strip will be trimmed, formed, and cut off respectively, with good synchronization. Moreover, only one set of moving mold table and fixed mold table is needed, which effectively reduces the overall equipment cost and maintenance cost.
[0007] In an improved embodiment, the cutting grooves are two, located on the upper left and right sides of the cutting table, respectively. Each cutting groove includes a longitudinal groove segment extending in the front-to-back direction and a transverse groove segment extending in the left-to-right direction. The two transverse groove segments are located on the same straight line and between the two longitudinal groove segments. The length of the longitudinal groove segment is less than the length of the workpiece. The longitudinal groove segment is used to cut the left and right sides of the workpiece relative to the strip, and the transverse groove segment is used to cut the rear side of the previous workpiece to the front side of the next workpiece, thereby causing most of the edge of the workpiece to detach from the strip, so as to facilitate deformation in subsequent forming stations. The length of the longitudinal groove segment is less than the length of the workpiece, ensuring that the workpiece does not completely detach from the strip.
[0008] In an improved embodiment, the front and / or rear sides of the forming surface are provided with a downward first bend, thereby enabling the workpiece to deform along the first bend.
[0009] In an improved embodiment, the fixed mold table is further provided with a pre-pressing station located between the trimming station and the forming station. The pre-pressing station includes a pre-pressing table, the upper side of which is provided with a pre-pressing surface. The front and / or rear sides of the pre-pressing surface are provided with a second bending portion, the bending angle of which is greater than that of the first bending portion. The moving mold table is provided with a pre-pressing head corresponding to the pre-pressing station, so that the workpiece is pre-pressed and deformed first through the pre-pressing station, so that the subsequent workpiece can be better formed when it enters the forming station, effectively reducing the probability of the workpiece cracking due to excessive deformation at one time.
[0010] In an improved embodiment, the cutting station has two cutting tables located on the left and right sides of the material drop hole, respectively. The cutting tables of the cutting station, together with the cutting pressure head, completely cut off the remaining connection position of the workpiece relative to the material strip.
[0011] In an improved embodiment, the fixed mold table is further provided with a punching station located between the forming station and the cutting station. The punching station includes a punching table, the upper side of which has the same shape as the forming surface, and a clearance hole is provided on the upper side of the punching table. The moving mold table is provided with a punching head corresponding to the punching station, so that the workpiece can be punched through the punching station according to design requirements.
[0012] In an improved embodiment, the cutting groove extends vertically through the cutting table, and a conveyor belt is provided at a position below the cutting table to collect and transfer the waste material falling from the cutting groove via the conveyor belt. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0023] Please see Figures 1-4 The present invention provides an energy-absorbing box stamping continuous forming mold, including a fixed mold table 1 and a movable mold table 2 that can be lifted and lowered above the fixed mold table 1. The fixed mold table 1 is provided with a trimming station, a forming station and a cutting station from front to back. The trimming station includes a trimming table 3, and a trimming groove 31 is provided on the upper side of the trimming table 3. The forming station includes a forming table 4, and a forming surface 41 is provided on the upper side of the forming table 4. The cutting station includes a cutting table 5 and a blanking hole 52 opened on the upper side of the fixed mold table 1. The cutting table 5 is arranged adjacent to the blanking hole 52, and a cutting support part 51 is provided on the side of the cutting table 5 near the blanking hole 52. The movable mold table 2 is provided with a trimming pressure head 21 corresponding to the trimming station, a forming pressure head 22 corresponding to the forming station and a cutting pressure head 23 corresponding to the cutting station.
[0024] Compared with the existing technology, the above solution integrates the trimming station, forming station and cutting station on the same fixed mold table 1. When the strip is conveyed from front to back, the trimming head 21 will cooperate with the trimming station to trim the corresponding position of the strip, the forming head 22 will cooperate with the forming station to form the corresponding position of the strip, and the cutting head 23 will cooperate with the cutting station to cut the corresponding position of the strip. That is, each time the moving mold table 2 punches, the three positions on the strip will be trimmed, formed and cut respectively, with good synchronization. Moreover, only one set of moving mold table 2 and fixed mold table 1 is needed, which effectively reduces the overall equipment cost and maintenance cost.
[0025] The trimming station is used to cut part of the workpiece's edge relative to the strip material, providing a basis for the subsequent deformation of the workpiece in the forming station. In this embodiment, there are two trimming grooves 31, located on the upper left and right sides of the trimming table 3, respectively. The trimming groove 31 includes a longitudinal groove segment 31a extending in the front-back direction and a transverse groove segment 31b extending in the left-right direction. The two transverse groove segments 31b are located on the same straight line and are located between the two longitudinal groove segments 31a. The length of the longitudinal groove segment 31a is less than the length of the workpiece. The longitudinal groove segment 31a is used to cut the left and right sides of the workpiece relative to the strip material, and the transverse groove segment 31b is used to cut the rear side of the previous workpiece to the front side of the next workpiece, thereby causing most of the workpiece's edge to detach from the strip material, so as to facilitate deformation in the subsequent forming station; while the length of the longitudinal groove segment 31a is less than the length of the workpiece, ensuring that the workpiece does not completely detach from the strip material.
[0026] The shape of the cutting head 21 corresponds to the upper side of the cutting table 3. Specifically, the lower side of the cutting head 21 is the same as the cutting groove 31. Thus, when the moving mold table 2 presses down, the cutting head 21 can cooperate with the cutting groove 31 to cut the edge of the workpiece relative to the strip.
[0027] In this embodiment, the front and / or rear sides of the forming surface 41 are provided with downward first bending portions 42, thereby enabling the workpiece to deform along the first bending portions 42. The forming surface 41 is designed according to the needs of the workpiece. Since the energy-absorbing box is generally U-shaped, the front and rear sides of the forming surface 41 are provided with first bending portions 42.
[0028] The shape of the forming head 22 corresponds to the upper side of the forming table 4. Specifically, the lower side of the forming head 22 has the same shape as the forming surface 41.
[0029] In this embodiment, the fixed mold table 1 is further provided with a pre-pressing station located between the trimming station and the forming station. The pre-pressing station includes a pre-pressing platform 6, with a pre-pressing surface 61 on its upper side. The front and / or rear sides of the pre-pressing surface 61 are provided with a second bending portion 62, the bending angle of which is greater than that of the first bending portion 42. The moving mold table 2 is provided with a pre-pressing head 24 corresponding to the pre-pressing station, thereby performing pre-pressing deformation through the pre-pressing station, so that the subsequent workpiece can be better formed when it enters the forming station, effectively reducing the probability of cracking due to excessive deformation of the workpiece at one time. The shape of the pre-pressing head 24 corresponds to the upper side of the pre-pressing platform 6, specifically, the lower side of the pre-pressing head 24 has the same shape as the pre-pressing surface 61.
[0030] In this embodiment, since the length of the longitudinal groove 31a is less than the length of the workpiece, there are remaining connection positions on the left and right sides of the workpiece relative to the strip. Therefore, there are two cutting tables 5 in the cutting station, located on the left and right sides of the drop hole 52, respectively. The position of the cutting head 23 corresponds to the cutting table 5 in the cutting station. More specifically, the cutting head 23 is directly opposite the cutting support part 51 of the cutting table 5. When the cutting head 23 presses down, it completely cuts off the remaining connection positions of the workpiece relative to the strip.
[0031] According to design requirements, it may be necessary to punch the workpiece. Therefore, in this embodiment, a punching station located between the forming station and the cutting station can be further provided on the fixed mold table 1. The punching station includes a punching table 7. The upper side of the punching table 7 has the same shape as the forming surface 41. An avoidance hole 71 is provided on the upper side of the punching table 7. The moving mold table 2 is provided with a punching pressure head 25 corresponding to the punching station, so that the workpiece can be punched through the punching station.
[0032] In this embodiment, the cutting groove 31 extends vertically through the cutting table 3, and the fixed mold table 1 is provided with a conveyor belt 11 located below the cutting table 3, so that the waste material falling from the cutting groove 31 can be collected and transferred by the conveyor belt 11.
