Technical Field

[0001] This utility model relates generally to the technical field of container production machinery, and more specifically to an automatic waste discharge assembly and a punch press. Background Technology

[0002] In related technologies, punch presses need to discharge waste material during processing. Waste material discharge is generally achieved using cylinders or other power-assisted methods. These technologies require an additional power source and sensors to coordinate the material discharge with the punch press's mold opening and closing actions, resulting in high programmability and cost. Utility Model Content

[0003] The present invention includes a series of simplified concepts, which will be further explained in detail in the detailed description section. This present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] To at least partially solve the above problems, the first aspect of this utility model provides an automatic waste discharge assembly, the automatic waste discharge assembly comprising:

[0005] A first link, the first end of which is adapted to be connected to the upper die holder of the punch press;

[0006] The second link has a first end adapted to be connected to the lower die holder of the punch press. The second link is rotatably connected to the first link about a first axis. The second link is the same as the first link. The first axis is located between the first end of the second link and the second end of the second link.

[0012] The second link is symmetrical to the first link about the plane containing the first axis and the fourth axis, and the first end of the first link, the first axis and the second axis are not coplanar.

[0013] According to the automatic waste removal assembly of this utility model, when applied to a punch press, the first end of the first connecting rod is connected to the upper die holder, and the first end of the second connecting rod is connected to the lower die holder. This allows the motion of the upper die holder relative to the lower die holder to drive the first connecting rod to rotate around the first axis relative to the second connecting rod, thereby linking the third, fourth, fifth, and sixth connecting rods. This, in turn, drives the material transfer component to move, achieving the purpose of discharging waste material from the lower die holder. By adopting the above technical solution, no additional power source is required, and no modification to the punch press's automation control program is needed. This not only helps reduce costs but also facilitates the application of the automatic waste removal assembly to the upgrading and modification of punch presses using related technologies, while also reducing the cost of punch press modification.

The first end of the first connecting rod is rotatably connected to the upper mold base around a sixth axis parallel to the first axis. The first end of the second connecting rod is rotatably connected to the lower mold base around a seventh axis parallel to the first axis. The material transfer member is movably connected to the guide portion along the first horizontal direction between a clearance position and a discharge position. The material transfer member protrudes from the upper surface of the lower mold base. The material transfer member in the clearance position is adapted to avoid the workpiece. During the process of the material transfer member moving from the clearance position to the discharge position, the material transfer member drives the waste material to move to the outside of the lower mold base.

[0033] According to the punch press of the second aspect of this utility model, by applying the aforementioned automatic waste removal assembly, the upper die assembly can be driven by the motion of the upper die assembly relative to the lower die assembly, thereby enabling the material transfer component to move relative to the lower die holder in the first horizontal direction, and thus discharging the waste material from the lower die holder. By adopting the above technical solution, no additional power source is required, and no modification to the punch press's automation control program is needed. This not only helps reduce costs but also does not affect the punch press's own program control.

[0066] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0067] This invention provides an automatic waste removal component 100 and a punch press having the automatic waste removal component 100. The punch press is used to perform processes such as punching sheet metal. This invention achieves the purpose of waste removal during the punch press processing by setting up the automatic waste removal component 100.

[0068] The following will be referred to Figures 1 to 4 The automatic waste discharge assembly 100 and the punch press having the automatic waste discharge assembly 100 provided in the embodiments of this utility model will be described in detail.

[0069] See Figure 1 and Figure 2The present invention provides an automatic waste removal assembly 100 in a first aspect. The automatic waste removal assembly 100 may include a first connecting rod 101, a second connecting rod 102, a third connecting rod 103, a fourth connecting rod 104, a fifth connecting rod 105, a sixth connecting rod 106, and a material transfer component 107. The first end of the first connecting rod 101 is adapted to connect to the upper die holder 121 of a punch press. The first end of the second connecting rod 102 is adapted to connect to the lower die holder 131 of the punch press. The second connecting rod 102 is rotatably connected to the first connecting rod 101 about a first axis AX1. The second connecting rod 102 is identical to the first connecting rod 101. The first axis AX1 is located between the first end and the second end of the second connecting rod 102. That is, the first axis AX1 is located at a certain intermediate position of the second connecting rod 102. Correspondingly, the first axis AX1 is located at a certain intermediate position of the first connecting rod 101. With the first end of the first link 101 connected to the upper mold base 121 and the first end of the second link 102 connected to the lower mold base 131, the first link 101 and the second link 102 rotate about the first axis AX1 as the upper mold base 121 moves relative to the lower mold base 131. The first end of the first link 101 moves in the opposite direction to the first end of the second link 102. The second end of the first link 101 moves in the opposite direction to the second end of the second link 102. The first end of the third link 103 is rotatably connected to the second end of the first link 101 about a second axis AX2 parallel to the first axis AX1. The first end of the fourth link 104 is rotatably connected to the second end of the second link 102 about a third axis AX3 parallel to the first axis AX1. The fourth link 104 is the same as the third link 103. The first end of the fifth link 105 is rotatably connected to the second ends of the third link 103 and the fourth link 104 about a fourth axis AX4 parallel to the first axis AX1. During the rotation of the first link 101 relative to the second link 102 about the first axis AX1, the second end of the first link 101 and the second end of the second link 102 move relative to each other. The third link 103 and the fourth link 104 apply a pushing or pulling force along the first horizontal direction D1 to the fifth link 105. The first end of the sixth link 106 is rotatably connected to the second end of the fifth link 105 about a fifth axis AX5 parallel to the first axis AX1. The transfer member 107 is connected to the second end of the sixth link 106. The transfer member 107 is located on the side of the first end of the first link 101 away from the second end of the first link 101. The sixth link 106 drives the transfer member 107 to move under the action of the pushing or pulling force transmitted by the fifth link 105. The transfer member 107 is adapted to be movably connected to the guide portion of the lower die holder 131 along the first horizontal direction D1 so as to discharge the waste material located in the lower die holder 131. The material transfer component 107 can discharge waste material to the outside of the lower mold base 131 by pushing or pulling the waste material.

[0070] The second link 102 is symmetrical to the first link 101 about the plane containing the first axis AX1 and the fourth axis AX4. When the automatic waste discharge assembly 100 is installed on the punch press, the plane containing the first axis AX1 and the fourth axis AX4 can be perpendicular to the height direction D3. The first end of the first link 101, the first axis AX1, and the second axis AX2 are not coplanar.

[0071] According to an embodiment of the present invention, the automatic waste removal assembly 100, when applied to a punch press, has its first end of the first connecting rod 101 connected to the upper die holder 121, and its first end of the second connecting rod 102 connected to the lower die holder 131. This allows the motion of the upper die holder 121 relative to the lower die holder 131 to drive the first connecting rod 101 to rotate relative to the second connecting rod 102 around the first axis AX1, thereby linking the third connecting rod 103, the fourth connecting rod 104, the fifth connecting rod 105, and the sixth connecting rod 106. This, in turn, drives the material transfer component 107 to move, achieving the purpose of discharging waste material from the lower die holder 131. By adopting the above technical solution, no additional power source is required, and no modification to the punch press's automation control program is needed. This not only helps reduce costs but also facilitates the application of the automatic waste removal assembly 100 to the modification and upgrading of punch presses using related technologies, while also reducing the cost of punch press modification.

[0072] Since the first link 101 and the second link 102 have the same structure, the following description will take the first link 101 as an example and will not describe the structure of the second link 102 separately.

[0073] The structure of the second link 102 is implemented with reference to the structure of the first link 101.

[0074] For example, the plane containing the first end of the first link 101 and the first axis AX1 forms a clamp with the plane containing the first axis AX1 and the second axis AX2. The plane containing the first end of the second link 102 and the first axis AX1 forms another clamp with the plane containing the first axis AX1 and the third axis AX3. The orientation of the first clamp is opposite to the orientation of the other clamp. Preferably, the first clamp is arranged facing upwards, and the other clamp is arranged facing downwards.

[0075] See Figure 1 and Figure 2 In some embodiments, the distance between the second axis AX2 and the first axis AX1 is greater than the distance between the first axis AX1 and the first end of the first connecting rod 101. This increases the travel distance of the material transfer component 107.

[0076] In some other embodiments, the distance between the second axis AX2 and the first axis AX1 may be less than or equal to the distance between the first axis AX1 and the first end of the first connecting rod 101. In these embodiments, the movable stroke of the transfer member 107 is relatively small.

[0077] See Figure 1 and Figure 2 In some embodiments, the distance between the fourth axis AX4 and the fifth axis AX5 is greater than the distance between the second axis AX2 and the first end of the first connecting rod 101. This increases the travel distance of the material transfer member 107. In this embodiment, the material transfer member 107 can be driven to move towards the discharge position by the movement of the upper mold base 121 and the lower mold base 131 away from each other, thereby achieving the purpose of discharging waste material.

[0078] In some other embodiments, the distance between the fourth axis AX4 and the fifth axis AX5 can be less than the distance between the second axis AX2 and the first end of the first connecting rod 101. Compared to the technique where the distance between the fourth axis AX4 and the fifth axis AX5 is greater than the distance between the second axis AX2 and the first end of the first connecting rod 101, the direction of movement of the material transfer member 107 will be different. For example, the movement of the upper mold base 121 and the lower mold base 131 closer to each other can be used to drive the material transfer member 107 to move towards the discharge position, thereby achieving the purpose of discharging waste material.

[0079] See Figure 1 and Figure 2 In some embodiments, the first link 101 may include a first link portion 101a, a second link portion 101b, a third link portion 101c, and a fourth link portion 101d arranged sequentially. The first link portion 101a and the second link portion 101b are arranged intersecting to form a first clamping opening α. The first axis AX1 is located at the connection between the first link portion 101a and the second link portion 101b. The second link portion 101b and the third link portion 101c are arranged intersecting to form a second clamping opening α. The orientation of the second clamping opening α is opposite to that of the first clamping opening α. The third link portion 101c and the fourth link portion 101d are arranged intersecting to form a third clamping opening α. The orientation of the third clamping opening α is the same as that of the first clamping opening α. By providing two intersecting structures between the second axis AX2 and the first axis AX1, the movable stroke of the material transfer member 107 can be increased while the space occupied by the first link 101 is reduced, thereby improving the flexibility of the movement of the first link 101.

[0080] In some other embodiments, a number of intersecting structures, such as three or more, are provided between the second axis AX2 and the first axis AX1. The clamps of adjacent intersecting structures face opposite directions.

[0081] In some other embodiments, the first link 101 may be a V-shaped member. Correspondingly, the second link 102 is also a V-shaped member. The orientation of the V-shaped clamp of the first link 101 is opposite to the orientation of the V-shaped clamp of the second link 102. Preferably, the V-shaped clamp of the first link 101 faces upward, and the V-shaped clamp of the second link 102 faces downward.

[0082] In some embodiments, the angle of the first clamp α is smaller than the angle of the second clamp α.

[0083] In other embodiments, the angle of the second clamp α is smaller than the angle of the third clamp α.

[0084] See Figure 1 and Figure 2 In some embodiments, the angle of the first clamp α is smaller than the angle of the second clamp α. Furthermore, the angle of the second clamp α is smaller than the angle of the third clamp α. This increases the travel distance of the material transfer component 107 while ensuring the normal movement of the first connecting rod 101.

[0085] See Figure 1 and Figure 2 In some embodiments, the length of the second rod 101b is less than the length of the first rod 101a and the length of the third rod 101c. This reduces the space occupied by the second rod 101b, thereby improving its adaptability to confined spaces and its flexibility of movement.

[0086] See Figure 1 and Figure 2 In some embodiments, the fourth axis AX4 is located on the side of the plane containing the second axis AX2 and the third axis AX3 that is away from the first axis AX1. This increases the movable stroke of the transfer member 107, while also preventing the third link 103 and the fourth link 104 from having too much room to move, and making assembly easier.

[0087] See Figure 1 and Figure 2In some embodiments, the automatic waste discharge assembly 100 may include a pair of first links 101, a pair of second links 102, a pair of third links 103, a pair of fourth links 104, a pair of fifth links 105, a pair of sixth links 106, and a pair of transfer elements 107. The pair of first links 101 are spaced apart along a second horizontal direction D2 parallel to the first axis AX1. The pair of second links 102 are spaced apart along a second horizontal direction D2 parallel to the first axis AX1. The pair of third links 103 are spaced apart along a second horizontal direction D2 parallel to the first axis AX1. The pair of fourth links 104 are spaced apart along a second horizontal direction D2 parallel to the first axis AX1. The pair of fifth links 105 are spaced apart along a second horizontal direction D2 parallel to the first axis AX1. The pair of sixth links 106 are spaced apart along a second horizontal direction D2 parallel to the first axis AX1. The pair of transfer elements 107 are spaced apart along a second horizontal direction D2 parallel to the first axis AX1. By setting up a pair of the above-mentioned components, it is beneficial to transmit power to the automatic waste discharge assembly 100 more evenly between the upper mold base 121 and the lower mold base 131, thereby helping to discharge waste more smoothly and steadily through the material transfer component 107.

[0088] See Figure 3 and Figure 4 and combined Figure 1 and Figure 2This utility model also provides a punch press. The punch press may include an upper die assembly 120, a lower die assembly 130, and the aforementioned automatic waste removal assembly 100. The upper die assembly 120 includes an upper die base 121 and an upper die 122. The lower die assembly 130 is located below the upper die assembly 120. The lower die assembly 130 includes a lower die base 131 and a lower die 132. The lower die base 131 is provided with a guide portion. The automatic waste removal assembly 100 is located outside the upper die assembly 120 in a first horizontal direction D1. The first end of the first connecting rod 101 is rotatably connected to the upper die base 121 about a sixth axis AX6 parallel to the first axis AX1. The first end of the second connecting rod 102 is rotatably connected to the lower die base 131 about a seventh axis AX7 parallel to the first axis AX1. The material transfer member 107 is movably connected to the guide portion along the first horizontal direction D1 between a clearance position and a discharge position. During the movement of the upper die assembly 120 relative to the lower die assembly 130 in the height direction D3, the transfer member 107 moves between a clearance position and a discharge position along the first horizontal direction D1. The transfer member 107 protrudes from the upper surface of the lower die base 131. The transfer member 107 in the clearance position is adapted to avoid the workpiece. During the movement of the transfer member 107 from the clearance position to the discharge position, the transfer member 107 drives the waste material to move to the outside of the lower die base 131. The upper die 122 and the lower die 132 are arranged opposite each other to achieve one or more processing purposes such as stamping and punching of sheet metal. The movement of the upper die assembly 120 toward the lower die assembly 130 can be called "die closing". The movement of the upper die assembly 120 away from the lower die assembly 130 can be called "die opening".

[0089] According to the embodiments of this utility model, the punch press, by applying the aforementioned automatic waste removal assembly 100, can be driven by the motion of the upper die assembly 120 relative to the lower die assembly 130, thereby enabling the material transfer component 107 to move relative to the lower die holder 131 in the first horizontal direction D1, and thus discharge the waste material from the lower die holder 131. By adopting the above technical solution, no additional power source is required, and no modification to the punch press's automation control program is needed. This not only helps reduce production costs but also does not affect the punch press's own program control. Compared to related technologies using other power sources, it reduces the complexity of program control. Furthermore, it improves production efficiency and product quality.

[0090] See Figures 1 to 4 In some embodiments, a first connecting lug 111 may be provided between the first end of the first connecting rod 101 and the upper mold base 121. The first connecting lug 111 is fixed to the upper mold base 121. The first connecting rod 101 is rotatably connected to the first connecting lug 111 about a sixth axis AX6. A second connecting lug 112 may be provided between the first end of the second connecting rod 102 and the lower mold base 131. The second connecting lug 112 is fixed to the lower mold base 131. The second connecting rod 102 is rotatably connected to the second connecting lug 112 about a seventh axis AX7.

[0091] Continue reading Figures 1 to 4 In some embodiments, the sixth link 106 is movably connected to the guide (not shown) along the first horizontal direction D1. This arrangement reduces the swaying of the sixth link 106 in the second horizontal direction D2, which is perpendicular to the first horizontal direction D1, thereby improving the movement accuracy and stability of the sixth link 106.

[0092] Optionally, the sixth link 106 extends along the first horizontal direction D1. The sixth link 106 is fixed to the transfer member 107.

[0093] See Figure 3 and Figure 4 In some embodiments, the distance between the transfer member 107 located in the avoidance position and the seventh axis AX7 is a first distance. The distance between the transfer member 107 located in the discharge position and the seventh axis AX7 is a second distance. The first distance is greater than the second distance. That is, compared to the transfer member 107 located in the discharge position, the transfer member 107 located in the avoidance position is closer to structures such as the first connecting rod 101 and the second connecting rod 102. As the upper mold assembly 120 moves away from the lower mold assembly 130 in the height direction D3, the transfer member 107 pulls the waste material to move outward of the lower mold base 131.

[0094] See Figure 1 In some embodiments, the upper part of the transfer member 107 has a guide surface 107a adapted to guide the falling waste material. The upper and lower ends of the guide surface 107a are spaced apart in a first horizontal direction D1. By providing the guide surface 107a, it is possible to ensure that the waste material falls smoothly and prevents it from being partially suspended due to interference.

[0095] In the illustrated example, guide surface 107a is a plane inclined to the height direction D3.

[0096] In some embodiments, the guide portion may be configured as a guide groove. The cross-section of the guide groove perpendicular to the first horizontal direction D1 may be dovetail-shaped, inverted T-shaped, or the like.

[0097] Furthermore, one of the upper mold assembly 120 and the lower mold assembly 130 may also include a guide sleeve 123. The other of the upper mold assembly 120 and the lower mold assembly 130 may also include a guide post 133. Through the cooperation of the guide sleeve 123 and the guide post 133, the upper mold assembly 120 and the lower mold assembly 130 are guided to move in the height direction D3.

[0098] The working principle of the punch press in this embodiment of the utility model is as follows:

[0099] When the punch press performs blanking, the upper die assembly 120 moves downward and drives the first connecting rod 101, which in turn drives the second connecting rod 102, the third connecting rod 103, the fourth connecting rod 104, the fifth connecting rod 105, and the sixth connecting rod 106 to move, pushing the transfer component 107 to the origin. The origin is the position where the transfer component 107 can avoid the workpiece.

[0100] After the blanking is completed, when the upper die assembly 120 moves upward, it drives the first connecting rod 101, and at the same time drives the second connecting rod 102, the third connecting rod 103, the fourth connecting rod 104, the fifth connecting rod 105 and the sixth connecting rod 106 to move, so as to move the material transfer component 107 to the edge of the lower die base 131, thereby automatically discharging the waste material.

[0101] The automatic waste removal component 100 and the punch press incorporating it according to this utility model employ a linkage mechanism, utilizing the power of the punch press's mold opening and closing to achieve automated waste removal. The structure is reliable with a low failure rate. It improves production efficiency and reduces labor costs. Furthermore, it requires no additional power assistance, resulting in low operating costs, strong economic efficiency, and high applicability. It possesses high practical value and widespread application potential. The automatic waste removal component 100 is particularly effective for high-speed punch presses.
