Description

Technical Field

[0001] This disclosure relates to the field of mold stamping technology, specifically to a material lifting and discharging assembly and a stamping die. Background Technology

[0002] In related technologies, when stamping dies process long and straight stamping parts such as side beams and other beam structures, due to the large length of the stamping parts, interference with the functional mechanism of the die can easily occur during separation and ejection after the die is formed, resulting in the inability to separate or eject the parts. Summary of the Invention

[0003] This disclosure aims to at least partially address one of the technical problems in the related art.

[0004] Therefore, embodiments of this disclosure provide a lifting and discharging assembly that facilitates the lifting and discharging of stamped parts, thereby improving the output efficiency of stamped parts.

[0005] Embodiments of this disclosure also provide a stamping die.

[0006] The material lifting and discharging assembly of embodiments of this disclosure includes: A movable frame, the top surface of which is used to support the stamped part; A driving assembly is disposed on the lower die base of the stamping die and connected to the movable frame. The driving assembly is used to drive the movable frame to move in the vertical direction so that the movable frame has a stamping position and a discharge position. In the stamping position, the movable frame is supported on the lower die base. In the discharge position, the movable frame is located above the lower die base and has a first distance between it and the lower die base. A flipping assembly, the flipping assembly including a flipping plate, the flipping plate being rotatably disposed on the movable frame for driving the stamping part away from the movable frame.

[0007] The lifting and unloading assembly of this embodiment facilitates the adjustment of the position and height of the stamped part by setting a movable frame, avoiding obstruction of the stamped part by other components during the unloading operation. By setting a flipping assembly, the flipping plate can rotate at a set angle, and during the rotation, it drives the stamped part to move away from the flipping plate on the movable frame, thereby realizing the adjustment of the position of the stamped part on the movable frame, which facilitates the unloading operation of the stamped part. At the same time, the linkage control of the drive assembly and the flipping assembly can realize the braking lifting and unloading operation of the stamped part, further improving the output efficiency of the stamped part.

[0008] In some embodiments, the drive assembly is a nitrogen spring; or, The drive component is a hydraulic telescopic cylinder; or... The drive assembly is a pneumatic telescopic cylinder; or... The drive component is an electric telescopic cylinder.

[0009] In some embodiments, at least two drive components are provided at intervals along the front-to-back direction. By providing at least two drive components, the connection reliability between the movable frame and the lower mold base, as well as the reliability and stability of the movable frame when it is adjusted in the vertical direction, are improved.

[0010] In some embodiments, the flip plate has a maximum rotation angle relative to the movable frame, the maximum rotation angle being in the range of 60° to 180°.

[0011] In this embodiment, by limiting the maximum rotation angle of the flip plate, the rotation position of the flip plate is effectively controlled, which facilitates the discharge of stamped parts and reduces interference between the flip plate and other components of the upper module or stamping die during the rotation process, thereby improving the continuity and reliability of the flip plate rotation process.

[0012] In some embodiments, the flipping assembly includes a drive shaft and a drive motor. The drive shaft extends in a front-to-back direction and is rotatably mounted on the movable frame. The drive shaft is fixedly connected to the flipping plate, and the drive motor is fixedly mounted on the movable frame and is drively connected to the drive shaft.

[0013] In this embodiment, the rotation of the tilting plate is easily adjusted by setting a drive shaft and a drive motor. It is also easy to install and reliable to drive, which greatly improves the material discharge efficiency of stamped parts.

[0014] In some embodiments, the flip plate is generally L-shaped and includes a horizontal plate segment and a vertical plate segment. The end of the horizontal plate segment away from the vertical plate segment is rotatably connected to the movable frame, and the vertical plate segment is used to block the stamping frame in the left-right direction.

[0015] In this embodiment, by setting the flip plate to be roughly L-shaped, the vertical plate section can restrict the stamping parts while meeting the requirements for adjusting the position of the stamping parts for material discharge. This prevents the stamping parts from shifting in position and from moving towards the flip plate, which would affect the collection of the stamping parts and reduce the material discharge efficiency.

[0016] In some embodiments, the thickness of the horizontal plate segment increases in the direction close to the vertical plate segment. By limiting the thickness of the horizontal plate, the structural strength of the flip plate can be increased, thereby improving the reliability of the flip plate during use.

[0017] In some embodiments, the top of the horizontal plate segment is provided with an inclined surface, and the end of the inclined surface away from the vertical plate segment is lower than the end of the inclined surface near the vertical plate segment.

[0018] In this embodiment, by setting an inclined surface at the top of the horizontal plate segment, when the horizontal segment rotates by the same angle, the inclined surface has a larger slope than the horizontal surface, which means that the effect of pushing the stamping part relative to the movable frame is better, and the material discharge efficiency of the stamping part is further improved.

[0019] In some embodiments, a guide rod is provided on one side of the movable frame, and at least two guide rods are spaced apart in the front-back direction. By setting the guide rod, it is convenient to guide the drop position of the stamped parts discharged from the movable frame, thereby facilitating the collection of the stamped parts and further improving the discharge efficiency of the stamped parts.

[0020] In some embodiments, the guide rod is inclined, with the end of the guide rod furthest from the movable frame being lower than the end of the guide rod connected to the movable frame.

[0021] In this embodiment, by setting an inclined guide rod, when the stamped part moves onto the guide rod, it can slide down the guide rod under its own weight, avoiding the stamped part from accumulating on the guide rod, facilitating the collection of the stamped part, and thus improving the discharge efficiency of the stamped part.

[0022] The stamping dies of embodiments of this disclosure include the material lifting and discharging assembly of any of the above embodiments. Attached Figure Description

[0028] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0029] The following is a reference appendix. Figures 1 to 3 A lifting and discharging assembly is described in accordance with embodiments of the present disclosure.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the lifting and discharging assembly 100 of the present disclosure includes a movable frame 1, a driving assembly 2 and a flipping assembly 3. The thickness direction of the movable frame 1 is defined as the vertical direction, the length direction of the movable frame 1 is defined as the front-back direction, and the width direction of the movable frame 1 is defined as the left-right direction.

[0031] The top surface of the movable frame 1 is used to support the stamping part 7. The drive assembly 2 is located on the lower die base 5 of the stamping die and connected to the movable frame 1. The drive assembly 2 is used to drive the movable frame 1 to move in the vertical direction so that the movable frame 1 has a stamping position and a discharge position. In the stamping position, the movable frame 1 is supported on the lower die base 5. In the discharge position, the movable frame 1 is located above the lower die base 5 and has a first distance between it and the lower die base 5. It should be noted that the first distance is greater than the distance between the top of other fixed components on the lower die base 5, such as the side-tilting wedge, and the lower die base 5, so that the stamping part 7 will not be blocked or interfered with when moving in the left and right directions. The flipping assembly 3 includes a flipping plate 31, which is rotatably located on the movable frame 1 to drive the stamping part 7 away from the movable frame 1.

[0032] In use, the lifting and unloading assembly 100 of this embodiment has the movable frame 1 in the stamping position, the upper die holder 6 moving towards the lower die holder 5 to perform stamping operations on the stamped part 7, the upper die holder 6 resetting, and the drive assembly 2 driving the movable frame 1 to the unloading position through extension operations, thus completing the lifting operation of the stamped part 7. The flipping plate 31 rotates relative to the movable frame 1, and the flipping plate 31 drives the side of the stamped part 7 that is in contact with the flipping plate 31 to have an upward tendency, thereby causing the stamped part 7 as a whole to move away from the flipping plate 31. When the flipping plate 31 moves into position, the unloading operation of the stamped part 7 is completed, and the flipping plate 31 and the movable frame 1 are reset to prepare for the stamping operation and unloading operation of the next stamped part 7.

[0033] The lifting and unloading assembly 100 of this embodiment facilitates the adjustment of the position and height of the stamped part 7 by setting a movable frame 1, avoiding obstruction of the stamped part 7 by other components during the unloading operation. By setting a flipping assembly 3, the flipping plate 31 can also rotate at a set angle, and during the rotation, it drives the stamped part 7 to move away from the flipping plate 31 on the movable frame 1, thereby realizing the adjustment of the position of the stamped part 7 on the movable frame 1, which facilitates the unloading operation of the stamped part 7. At the same time, the linkage control of the drive assembly 2 and the flipping plate assembly can realize the braking, lifting and unloading operation of the stamped part 7, further improving the output efficiency of the stamped part 7.

[0034] In some implementations, the drive component 2 is a nitrogen spring.

[0035] In some implementations, the drive component 2 is a hydraulic telescopic cylinder.

[0036] In some implementations, the drive component 2 is a pneumatic telescopic cylinder.

[0037] In some implementations, the drive component 2 is an electric telescopic cylinder.

[0038] In some embodiments, the fixed end of the drive component 2 is fixedly connected to the lower mold base 5, and the movable end of the drive component 2 is fixedly connected to the movable frame 1.

[0039] In some embodiments, the fixed end of the drive assembly 2 is rotatably connected to the lower mold base 5 via a first shaft, and the movable end of the drive assembly 2 is rotatably connected to the movable frame 1 via a second shaft, wherein the extension direction of the first shaft is perpendicular to the extension direction of the second shaft.

[0040] In some implementations, such as Figure 1 and Figure 2 As shown, at least two drive components 2 are spaced apart along the front-to-back direction. By setting at least two drive components 2, the connection reliability between the movable frame 1 and the lower mold base 5, as well as the reliability and stability of the movable frame 1 when it is adjusted in the up-down direction, are improved.

[0041] In some embodiments, the drive components 2 are provided with two, three, four or five spaced apart in the front-to-back direction.

[0042] In some embodiments, the flip plate 31 has a maximum rotation angle relative to the movable frame 1, and the maximum rotation angle ranges from 60° to 180°.

[0043] In this embodiment, by limiting the maximum rotation angle of the flip plate 31, the rotation position of the flip plate 31 is effectively controlled, which facilitates the discharge of the stamping parts 7 and reduces interference between the flip plate 31 and other components of the upper module or stamping die during the rotation process, thereby improving the continuity and reliability of the flip plate 31 during the rotation process.

[0044] In some implementations, the maximum rotation angle is 60°, 75°, 90°, 105°, 120°, 135°, 150°, 165°, or 180°.

[0045] In some implementations, such as Figure 1 , Figure 2 and Figure 3 As shown, the flipping assembly 3 includes a drive shaft 32 and a drive motor. The drive shaft 32 extends in the front-to-back direction and is rotatably mounted on the movable frame 1. The drive shaft 32 is fixedly connected to the flipping plate 31. The drive motor is fixedly mounted on the movable frame 1 and is connected to the drive shaft 32 in a transmission manner.

[0046] In this embodiment, the drive motor drives the drive shaft 32 to rotate through the transmission assembly, and the drive shaft 32 drives the tilting plate 31 to rotate. By setting the drive shaft 32 and the drive motor, it is easy to adjust the rotation of the tilting plate 31, and the installation is convenient and the drive is reliable, which greatly improves the material discharge efficiency of the stamped parts 7.

[0047] In some embodiments, the drive motor and the drive shaft 32 are connected by gear transmission or coupling.

[0048] In some implementations, such as Figure 3 As shown, the flip plate 31 is generally L-shaped and includes a horizontal plate segment 311 and a vertical plate segment 312. The end of the horizontal plate segment 311 away from the vertical plate segment 312 is rotatably connected to the movable frame 1, that is, the drive shaft 32 is fixedly installed. The vertical plate segment 312 is used to block the stamping frame in the left and right directions.

[0049] In this embodiment, by setting the flip plate 31 to be generally L-shaped, the vertical plate section 312 can restrict the stamping part 7 while meeting the requirements for material discharge by adjusting the position of the stamping part 7, thereby preventing the stamping part 7 from shifting position and moving towards the flip plate 31, which would affect the collection of the stamping part 7 and reduce the material discharge efficiency of the stamping part 7.

[0050] In some implementations, such as Figure 3 As shown, the thickness of the horizontal plate segment 311 increases along the direction close to the vertical plate segment 312. By limiting the thickness of the horizontal plate, the structural strength of the flip plate 31 can be increased, thereby improving the reliability of the flip plate 31 during use.

[0051] In some implementations, such as Figure 3 As shown, the top of the horizontal plate segment 311 is provided with an inclined surface, and the end of the inclined surface away from the vertical plate segment 312 is lower than the end of the inclined surface near the vertical plate segment 312.

[0052] In this embodiment, by setting an inclined surface at the top of the horizontal plate segment 311, when the horizontal segment rotates by the same angle, the inclined surface has a larger slope than the horizontal surface, which means that the effect of pushing the stamping part 7 to move relative to the movable frame 1 is better, and the discharge efficiency of the stamping part 7 is further improved.

[0053] In some implementations, such as Figure 3 As shown, when the flip plate 31 is in the initial position, the bottom surface of the horizontal plate segment 311 is set horizontally, and the top surface of the horizontal plate segment 311 is set inclined. The end of the inclined surface away from the vertical plate segment 312 is lower than the end of the inclined surface close to the vertical plate segment 312. As a result, the thickness of the horizontal plate segment 311, that is, the dimension in the vertical direction, increases along the direction close to the vertical plate segment 312.

[0054] In some implementations, such as Figure 1 and Figure 2 As shown, a guide rod 4 is provided on one side of the movable frame 1. At least two guide rods 4 are spaced apart in the front-back direction. By setting the guide rods 4, it is convenient to guide the dropping position of the stamped parts 7 discharged from the movable frame 1, thereby facilitating the collection of the stamped parts 7 and further improving the discharge efficiency of the stamped parts 7.

[0055] In some embodiments, the top surface of the guide rod 4 is a plane. The plane increases the contact area between the guide rod and the stamping part 7, thereby improving the reliability of the stamping part 7 when it moves on the guide rod 4.

[0056] In some implementations, such as Figure 1 and Figure 2 As shown, the guide rod 4 is inclined, and the end of the guide rod 4 away from the movable frame 1 is lower than the end of the guide rod 4 connected to the movable frame 1.

[0057] In this embodiment, by setting an inclined guide rod 4, when the stamped part 7 moves onto the guide rod 4, it can slide down the guide rod 4 under its own weight, avoiding the stamped part 7 from accumulating on the guide rod 4, making it easier to collect the stamped part 7, thereby improving the discharge efficiency of the stamped part 7.

[0058] Embodiments of this disclosure also provide a stamping die.

[0059] like Figure 4 As shown, the stamping die of the present disclosure includes the lifting and discharging assembly 100 of any of the above embodiments.

[0060] The movable frame 1 is set between the upper mold base 6 and the lower mold base 5. The drive component 2 is fixedly set on the lower mold base 5 and extends in the vertical direction. The drive component 2 is used to drive the movable frame 1 in the vertical direction. The lower mold base 5 is provided with a discharge side. The flipping component 3 is set at the position of the movable frame 1 away from the discharge side.
