Description

Technical Field

[0001] This application belongs to the field of stamping die technology, and particularly relates to a device for adjusting the height of a balance block, a balance block system, and a stamping die. Background Technology

[0002] The balance block is a key component in stamping dies. Traditional balance blocks are solid cylindrical or rectangular metal blocks. By adding or removing shims under the balance block, the height of the balance block can be changed, thereby adjusting the mold clearance between the upper and lower dies and controlling the forming result of the stamped parts.

[0003] Traditional balance blocks do not have the function of automatically changing their height. If the balance block height needs to be adjusted, the press must be stopped, the balance block must be manually removed, and then balance block shims must be added or removed at the bottom of the balance block. The balance block removal and installation time is long, and the equipment downtime affects production efficiency, which is a key factor restricting stamping production. Utility Model Content

[0004] The purpose of this application is to provide a device, a balance block system, and a stamping die for adjusting the height of a balance block, so as to solve the technical problem in the prior art that traditional balance blocks require the addition or removal of shims to adjust their height, which affects the stamping production efficiency.

[0018] In some implementations, the side of the housing with a visible window is called the window side, and a boss is provided on the window side. The top surface of the boss is flush with the area below the window hole wall along the height direction, and the scale line extends to the top surface of the boss.

[0019] In some implementations, an anti-detachment structure is formed between the balance block and the housing to prevent the balance block from detaching from the housing through the opening.

[0020] A second aspect of this application provides a balance block system, including a balance block and a device for adjusting the height of the balance block as provided in any of the above technical solutions, wherein the balance block is located on the support surface of the device.

[0053] Please see Figures 1-2 , Figure 1 A schematic diagram of the structure of the device 100 for adjusting the height of the balance block and the balance block 200 provided in the embodiments of this application; Figure 2 This is a cross-sectional schematic diagram showing the interaction between the device 100 for adjusting the height of the balance block 200 and the balance block 200, as provided in an embodiment of this application. For ease of description, in this embodiment, the width direction of the device 100 for adjusting the height of the balance block 200 is defined as the X-axis direction, the length direction of the device 100 for adjusting the height of the balance block 200 is defined as the Y-axis direction, and the height direction of the device 100 for adjusting the height of the balance block 200 is defined as the Z-axis direction, wherein the X-axis direction, Y-axis direction, and Z-axis direction are mutually perpendicular.

[0054] The device 100 for adjusting the height of the balance block provided in this application embodiment is used in a stamping die and can automatically adjust the height of the balance block 200 to meet the needs of adjusting the gap between the upper and lower dies.

[0055] Specifically, the device 100 for adjusting the height of the balance block includes a housing 1, a drive structure 2, and a shuttle block 3. See also... Figure 1The diagram illustrates housing 1. Housing 1 provides support for the drive structure 2 and the shuttle block 3. Please refer to [link / reference]. Figure 2 The diagram illustrates the drive structure 2 and the shuttle block 3 connected to the drive structure 2. When the drive structure 2 is working, it can drive the shuttle block 3 to move.

[0056] A support surface 301 is formed on the shuttle block 3, please refer to Figure 2 The balance block 200 is supported on the support surface 301 of the shuttle block 3. The support surface 301 is an inclined surface; please refer to [link / reference]. Figure 2 ,exist Figure 2 In the example, along the direction indicated by the arrow on the Y-axis, the height of the support surface 301 gradually increases along the Z-axis.

[0057] In one example, the balance block 200 is slidably connected to the housing 1 along the height direction. This can be understood as the housing 1 restricting the balance block 200 to move only vertically along the Z-axis relative to the housing 1. See also... Figure 2 When shuttle block 3 moves to the right along the direction indicated by the Y-axis arrow, the height of balance block 200 gradually decreases; when shuttle block 3 moves to the left along the direction opposite to the direction indicated by the Y-axis arrow, the height of balance block 200 gradually increases.

[0058] When the device 100 for adjusting the height of the balance block provided in this application embodiment is installed on the stamping die, the height of the balance block 200 can be adjusted simply by controlling the working state of the drive structure 2. Unlike traditional balance blocks, which require stopping the equipment and adjusting the height by adding or removing balance block shims, the device 100 for adjusting the height of the balance block provided in this application embodiment is easy to use, can quickly adjust the height of the balance block 200, and can achieve height adjustment without stopping the equipment or disassembling the balance block.

[0059] Regarding the balance block 200, in one embodiment, please refer to Figure 2 The bottom surface of the balance block 200 is in contact with the support surface 301, that is, the bottom surface of the balance block 200 is also an inclined surface, so as to achieve the fit between the bottom surface of the balance block 200 and the inclined support surface 301, so as to facilitate the balance block 200 to be better supported on the shuttle block 3.

[0060] Optionally, the top surface of the balance block 200 is a plane.

[0061] Optionally, the projection of the balance block 200 onto the shuttle block 3 falls on the shuttle block 3. This can be understood as the entire bottom area of ​​the balance block 200 being supported on the shuttle block 3 during the height adjustment process. If only a portion of the bottom area of ​​the balance block 200 is supported on the shuttle block 3, the unsupported portion of the bottom area of ​​the balance block 200 becomes suspended. However, the impact load during the stamping die production process is large, causing the balance block 200 to experience uneven stress.

[0062] Regarding the dimensional relationship between the balance block 200 and the shuttle block 3, specifically, the width of the balance block 200 along the X-axis is smaller than the width of the shuttle block 3 along the X-axis, and the length of the shuttle block 3 along the Y-axis is greater than the sum of the length of the balance block 200 along the Y-axis and the travel distance of the shuttle block 3 along the Y-axis. This ensures that during the height adjustment of the balance block 200, the entire bottom surface of the balance block 200 is always supported on the shuttle block 3. It should be noted that the travel distance of the shuttle block 3 refers to the maximum distance it moves along the Y-axis.

[0063] In this embodiment, by setting the entire area of ​​the bottom surface of the balance block 200 to be supported on the locking block 3 during the height adjustment process, the balance block 200 is subjected to balanced force, thereby improving the durability of the device 100 for adjusting the height of the balance block.

[0064] Regarding the drive structure 2, in one embodiment, the drive structure 2 is a linear drive mechanism, such as a drive cylinder. The telescopic shaft of the drive structure 2 is connected to the shuttle block 3. The drive structure 2 works to drive the shuttle block 3 to move in the horizontal direction, thereby adjusting the height of the balance block 200.

[0065] Regarding the drive structure 2, in another embodiment, the drive structure 2 includes a drive motor 201 and a transmission assembly, wherein the drive motor 201 is connected to the shuttle block 3 via the transmission assembly. See also... Figure 2 The diagram illustrates the drive motor 201. The drive motor 201 includes a rotating shaft 2011, which is connected to the shuttle block 3 via a transmission assembly. The motor housing of the drive motor 201 is fixed to the housing 1.

[0066] In this embodiment, the rotational motion of the rotating shaft 2011 is converted into the linear motion of the shuttle block 3 through a transmission assembly, thereby achieving the adjustment of the height of the balance block 200. Specifically, for example, when the rotating shaft 2011 of the drive motor 201 rotates in the forward direction, it drives... Figure 2 The shuttle block 3 moves to the right along the direction indicated by the Y-axis arrow, and the height of the balance block 200 gradually decreases; when the shaft 2011 of the drive motor 201 rotates in the opposite direction, it drives the shuttle block 3 to move to the left along the direction opposite to the direction indicated by the Y-axis arrow, and the height of the balance block 200 gradually increases.

[0067] In this embodiment, the rotational motion of the drive motor 201 is converted into the linear motion of the shuttle block 3 by the transmission component, so as to facilitate accurate adjustment of the height of the balance block 200.

[0068] Regarding the transmission component, in one embodiment, the transmission component is a gear and rack structure. The gear in the transmission component is connected to the rotating shaft 2011 of the drive motor 201, and the rack in the transmission component is connected to the shuttle block 3. The rotational motion of the rotating shaft 2011 is converted into the linear motion of the shuttle block 3 through the gear and rack structure, thereby realizing the adjustment of the height of the balance block 200.

[0069] Regarding the transmission assembly, in one embodiment, the transmission assembly includes a lead screw, one end of which is connected to the rotating shaft 2011 of the drive motor 201, and the other end of which passes through the shuttle block 3 and is threadedly connected to the shuttle block 3. The inner side of the housing 1 guides the shuttle block 3 so that the shuttle block 3 moves in a direction parallel to the axis of the lead screw. When the drive motor 201 is activated, the drive motor 201 drives the lead screw to rotate. When the lead screw rotates, it drives the shuttle block 3 to move in a horizontal direction. That is, through the cooperation of the lead screw and the shuttle block 3, the rotational motion of the rotating shaft 2011 is converted into the linear motion of the shuttle block 3, thereby realizing the adjustment of the height of the balance block 200.

[0070] Regarding the transmission assembly, in one embodiment, please refer to... Figure 2 The transmission assembly includes a lead screw 202 and a threaded block 203. The rotating shaft 2011 of the drive motor 201 is inserted into the lead screw 202 from one end of the lead screw 202. The lead screw 202 and the rotating shaft 2011 are slidably connected along the axial direction of the rotating shaft 2011. The threaded block 203 is fixed on the inner side of the housing 1. The lead screw 202 passes through the threaded block 203 and the two are threadedly connected. The other end of the lead screw 202 is rotatably connected to the shuttle block 3.

[0071] When the drive motor 201 is activated, the rotating shaft 2011 drives the lead screw 202 to rotate together. Since the lead screw 202 is threadedly connected to the threaded block 203 and the threaded block 203 is fixed on the inner side of the housing 1, the lead screw 202 moves along the axis of the rotating shaft 2011 while rotating. Because one end of the lead screw 202 is rotatably connected to the shuttle block 3, the rotation of the lead screw 202 does not drive the shuttle block 3 to rotate together, but the movement of the lead screw 202 along the axis of the rotating shaft 2011 will drive the shuttle block 3 to move together. That is, the rotational motion of the rotating shaft 2011 is converted into the linear motion of the shuttle block 3 through the lead screw 202 and the threaded block 203, thereby realizing the adjustment of the height of the balance block 200.

[0072] Please see Figure 3 and Figure 4 , Figure 3 and Figure 4 This is a cross-sectional schematic diagram of the device 100 for adjusting the height of the balance block provided in the embodiments of this application on the YOZ plane. Figure 3 and Figure 4 The black arrows in the image indicate the movement direction of shuttle block 3 and balance block 200.

[0073] Please see Figure 3 ,exist Figure 3 In the example, when the shaft 2011 rotates counterclockwise, the lead screw 202 and the shuttle block 3 move to the left, the shuttle block 3 moves upward along the Z-axis, and the height of the balance block 200 increases; see also Figure 4 ,exist Figure 4 In the example, when the shaft 2011 rotates clockwise, the lead screw 202 and the shuttle block 3 move to the right, the shuttle block 3 moves downward along the Z-axis, and the height of the balance block 200 decreases.

[0074] Regarding the connection between the rotating shaft 2011 and the lead screw 202, optionally, the lead screw 202 is provided with a rotating shaft insertion hole 2021. The cross-sectional shape of the rotating shaft insertion hole 2021 is consistent with the cross-sectional shape of the rotating shaft 2011. The rotating shaft 2011 can be positioned close to (but not tightly fitted) the wall of the rotating shaft insertion hole 2021, or a gap can be provided between the rotating shaft 2011 and the wall of the rotating shaft insertion hole 2021. Regarding the shape of the rotating shaft 2011, in one specific example, the cross-sectional shape of the rotating shaft 2011 is elliptical or polygonal; in other examples, please refer to [reference needed]. Figure 3 A horizontal cutting surface 2012 is formed on the rotating shaft 2011, that is, the shape of the rotating shaft 2011 is a cylindrical shaft with a cutting surface parallel to the axis. When the rotating shaft 2011 rotates, the rotating shaft 2011 can drive the lead screw 202 to rotate together, and the lead screw 202 will also move along the axial direction of the rotating shaft 2011.

[0075] The threaded block 203 is fixed to the inner side of the housing 1. In one example, the threaded block 203 is integrally formed with the housing 1, for example, the threaded block 203 is integrally cast with the housing 1; in other examples, the threaded block 203 is detachably fixed inside the housing 1 by a connector. Preferably, the threaded block 203 is integrally formed with the housing 1 to reduce the number of assembly parts of the device 100 for adjusting the height of the balance block.

[0076] The lead screw 202 is rotatably connected to the shuttle block 3. See a specific example. Figure 5 , Figure 5 This is a schematic diagram of the lead screw 202 provided in the embodiment of this application. The lead screw 202 has one or more annular protrusions 2022. The annular protrusions 2022 are located near one end of the lead screw 202. Please refer to [link / reference needed]. Figure 6 The shuttle block 3 is provided with a shuttle block insertion hole 304. The wall of the shuttle block insertion hole 304 is provided with an annular groove that mates with the annular protrusion 2022. When the lead screw 202 rotates, the shuttle block 3 does not rotate with the lead screw 202, but due to the engagement of the annular protrusion 2022 and the annular groove, the lead screw 202 can drive the shuttle block 3 to move horizontally together. Please refer to... Figure 5 ,exist Figure 5In the example, two annular protrusions 2022 are provided at intervals on the lead screw 202.

[0077] Please see Figure 6 ,exist Figure 6 In the example, the shuttle block insertion hole 304 extends to the bottom surface of the shuttle block 3, that is, the shuttle block insertion hole 304 has an opening on the bottom surface of the shuttle block 3, so that one end of the lead screw 202 with the annular protrusion 2022 can be inserted into the shuttle block insertion hole 304 through the opening.

[0078] Regarding the rotatable connection between the lead screw 202 and the shuttle block 3, in other examples, one end of the lead screw 202 can be rotatably connected to the shuttle block 3 via a bearing. Specifically, the outer ring of the bearing is fixed on the shuttle block 3, and one end of the lead screw 202 is fixedly connected to the inner ring of the bearing.

[0079] Optionally, the inner surface of the housing 1 can guide the shuttle block 3 to move horizontally. See also... Figure 7 , Figure 7 This is a cross-sectional view of the device 100 for adjusting the height of the balance block provided in this application embodiment on the XOZ plane. The bottom surface of the shuttle block 3 is a plane. Guide protrusions 303 are provided on two opposite sides of the shuttle block 3 along the direction perpendicular to the horizontal movement of the shuttle block 3. Please refer to [link to relevant documentation]. Figure 7 The diagram illustrates the guide protrusion 303. The length of the guide protrusion 303 extends along the moving direction of the shuttle block 3. A guide groove 109 is provided on the inner side of the housing 1. The guide protrusion 303 extends into the corresponding guide groove 109. Through the cooperation between the guide protrusion 303 and the guide groove 109, the inner side of the housing 1 guides the shuttle block 3 to move horizontally and restricts the shuttle block 3 to move along the Z-axis, so that the shuttle block 3 can move stably in the horizontal direction under the drive of the drive structure 2.

[0080] Optionally, the four corners of shuttle block 3 are chamfered.

[0081] The transmission assembly provided in this embodiment includes a lead screw 202 and a threaded block 203. The transmission assembly provides stable transmission and facilitates accurate adjustment of the height of the balance block 200. In addition, the drive structure 2 in this embodiment has a simple structure and is easy to process and assemble.

[0082] Regarding the positional relationship between the drive structure 2 and the shuttle block 3 on the housing 1, in one embodiment, please refer to [link to relevant documentation]. Figures 2-4 The housing 1 has a receiving cavity 101, the drive structure 2 and the shuttle block 3 are located in the receiving cavity 101; the top surface of the housing 1 has an opening 102, which is connected to the receiving cavity 101, and the balance block 200 is inserted into the opening 102 and located on the shuttle block 3.

[0083] In this embodiment, by placing the drive structure 2 and the shuttle block 3 inside the receiving cavity 101, the drive structure 2 and the shuttle block 3 are protected by the housing 1, thereby improving the service life of the drive structure 2.

[0084] Regarding housing 1, please refer to Figure 8 , Figure 8 The exploded view of the device 100 for adjusting the height of the balance block provided in the embodiment of this application shows that, in one embodiment, the housing 1 includes an upper cover 103 and a base 104. The upper cover 103 is supported on the base 104 and connected to the base 104. A receiving cavity 101 is formed between the upper cover 103 and the base 104.

[0085] Optionally, the upper cover 103 and the base 104 are detachably connected by connectors (such as bolts). For details, please refer to [link to relevant documentation]. Figure 8 A first mounting hole 1041 is provided on the base 104. There are multiple first mounting holes 1041. The connector passes through the first mounting hole 1041 from the bottom of the base 104 and is inserted into the upper cover 103 to realize the connection between the upper cover 103 and the base 104.

[0086] In a specific example, a second mounting hole 1042 is provided on the base 104. There are multiple second mounting holes 1042, and a connector (such as a bolt) can pass through the second mounting hole 1042 from the top of the base 104 to connect with the stamping die.

[0087] Optionally, the threaded block 203 of the drive structure 2 is integrally formed with the base 104.

[0088] For a specific example, please see Figure 8 The base 104 includes a first segment 1041 and a second segment 1042. The first segment 1041 is disposed on one side of the second segment 1042 and the two are connected. The first segment 1041 and the second segment 1042 are integrally formed along the width direction of the base 104. Figure 8 In the direction of the X-axis, the width of the first section 1041 of the base is greater than the width of the second section 1042 of the base.

[0090] In this embodiment, the housing 1 is provided with an upper cover 103 and a base 104 so that the drive structure 1, the shuttle block 3 and the balance block 200 can be assembled on the housing 1.

[0091] In one embodiment, an anti-detachment structure is formed between the balance block 200 and the housing 1 to prevent the balance block 200 from detaching from the housing 1 through the opening 102.

[0092] Regarding the anti-detachment structure formed between the balance block 200 and the housing 1, please refer to one example. Figure 8 The outer peripheral side of the balance block 200 is provided with an anti-detachment protrusion 210, which contacts the inner wall of the housing 1 receiving cavity 101 to prevent the balance block 200 from detaching from the housing 1 through the opening 102.

[0093] In one specific example, a single anti-detachment protrusion 210 is provided on the balance block 200. In other examples, two or more anti-detachment protrusions 210 are provided on the balance block 200, with each anti-detachment protrusion 210 located on a different side of the balance block 200.

[0094] In one specific example, the anti-slip protrusion 210 on the balance block 200 is located on one side near the bottom of the balance block 200.

[0095] In one specific example, the anti-detachment protrusion 210 is integrally formed with the balance block 200; in other examples, the anti-detachment protrusion 210 is welded to the balance block 200.

[0096] In one specific example, the anti-detachment protrusion 210 is detachably connected to the balance block 200.

[0097] Regarding the anti-detachment structure formed between the balance block 200 and the housing 1, in one example, a limiting protrusion is provided on the housing 1, and a limiting groove is provided on the balance block 200. The limiting protrusion extends into the limiting groove, the length direction of the limiting groove extends along the height direction of the balance block 200, and there is a gap between the limiting groove and the bottom surface of the balance block 200.

[0098] In one specific example, the top of the limiting groove extends to the top surface of the balance block 200.

[0099] In one specific example, there is one or more limiting protrusions and one or more limiting grooves, with each limiting protrusion corresponding to a limiting groove.

[0100] As mentioned above, the balance block 200 is slidably connected to the housing 1 along the height direction. In a specific example, the shape of the opening 102 matches the shape of the balance block 200, for example, see [reference needed]. Figure 8 The opening 102 is a square hole and the balance block 200 is a rectangular block, or for example, the opening 102 is a circular hole and the balance block 200 is a cylindrical shape. By matching the shape of the opening 102 with the shape of the balance block 200, the balance block 200 and the shell 1 can be slidably connected along the height direction.

[0101] In one example, one of the side surface of the balance block 200 and the wall surface of the opening 102 is provided with a groove, and the other is provided with a protrusion extending into the groove. The matching groove and protrusion guide the balance block 200 to move in the height direction.

[0102] In this embodiment, by providing an anti-detachment structure on the side of the balance block 200, the balance block 200 is prevented from detaching from the housing 1 through the opening 102, thereby stabilizing the overall structure of the device 100 for adjusting the height of the balance block.

[0103] Please see Figures 9-10 , Figure 9 This is a schematic diagram of the structure of the upper cover 103 provided in the embodiments of this application. Figure 10 for Figure 1 A magnified view of a portion of point A in the middle.

[0104] In one embodiment, please refer back to [link to previous document]. Figure 1 A viewing window 105 is provided on at least one of the two opposite sides of the housing 1. The viewing window 105 is connected to the receiving cavity 101 inside the housing 1. Please refer to [link to relevant documentation]. Figure 8 The shuttle block 3 is provided with scale lines 302 for observation through the viewing window 105. Please refer to [link / reference]. Figure 10 The housing 1 is provided with scale lines 106 that cooperate with the scale lines 302.

[0105] A viewing window 105 is provided on the housing 1. Preferably, the viewing window 105 is provided on the upper cover 103 of the housing 1. Please refer to [link / reference]. Figure 9 This illustrates the visible window 105 located on the upper cover 103, with the shuttle block 3 extending along the length of the upper cover 103. Figure 9 The movement along the Y-axis of the upper cover 103 is along the width direction. Figure 9 A view window 105 is provided on at least one of the two opposite sides along the X-axis.

[0106] When viewing windows 105 are provided on two opposite sides of the upper cover 103, scale lines 302 are provided on two opposite sides of the shuttle block 3, and the two scale lines 302 are observed through the two viewing windows 105 respectively. Scale lines 106 are provided on two opposite sides of the upper cover 103 along the width direction, and the scale lines 106 on each side correspond to the scale lines 302 on the shuttle block 3.

[0107] In this embodiment, by setting a scale line 302 on the shuttle block 3 and setting a scale line 106 on the housing 1 that cooperates with the scale line 302, the movement of the shuttle block 3 can be displayed intuitively and quantitatively. Different positions of the shuttle block 3 in the horizontal direction correspond to different heights of the balance block 200, which makes it easier to accurately adjust the height of the balance block 200.

[0108] In one embodiment, the viewing window 105 is a strip-shaped hole, and the length of the viewing window 105 extends along the moving direction of the shuttle block 3. The viewing window 105 includes a window hole wall 1051, and a scale line 106 is provided on the lower region of the window hole wall 1051 along the height direction. Please refer to [link to relevant documentation]. Figure 9 The diagram illustrates the scale lines 106 set on the wall surface 1051 of the window hole, with each scale of the scale lines 106 set sequentially along the length of the visible window 105.

[0109] In this embodiment, a scale line 106 is provided in the lower region along the height direction of the window hole wall 1051 to facilitate observation of the positional relationship between the scale line 106 and the ruler line 302.

[0110] In one embodiment, please refer to Figure 9 The side of the viewing window 105 on the housing 1 is called the window side 107. A boss 108 is provided on the window side 107. The top surface of the boss 108 is flush with the area below the window hole wall 1051 along the height direction. The scale line 106 extends to the top surface of the boss 108.

[0111] Please see Figure 9 The diagram illustrates the boss 108. In one example, the boss 108 extends along the length of the upper cover 103, and the bottom surface of the boss 108 is flush with the bottom surface of the upper cover 103.

[0112] When the upper cover 103 has two viewing windows 105 on its two opposite sides, two window sides 107 are formed on the housing 1. The two window sides 107 are arranged opposite each other and each window side 107 has a protrusion 108.

[0113] In this embodiment, by setting the top surface of the boss 108 to be flush with the area below the window hole wall 1051 along the height direction and extending the scale line 106 to the top surface of the boss 108, the length of each scale line 106 can be increased to facilitate observation of the scale line 106.

[0114] In one embodiment, please refer to Figure 8 The bottom surface of the boss 108 is provided with a downwardly extending positioning protrusion 110, and the base 104 is provided with a positioning groove 111, into which the positioning protrusion 110 is inserted.

[0115] When assembling the upper cover 103 and the base 104, the positioning protrusion 110 is inserted into the positioning groove 111 to achieve the positioning of the upper cover 103 and the base 104, so that the upper cover 103 and the base 104 can be further fixed by the connector.

[0117] The device 100 for adjusting the height of the balance block includes a housing 1, a drive structure 2, and a shuttle block 3. The specific structure of the device 100 for adjusting the height of the balance block has been described above and will not be repeated here.

[0118] In one example, the balance block 200 is slidably connected to the housing 1 along the height direction, meaning that the housing 1 restricts the balance block 200 to move only up and down along the Z-axis relative to the housing 1. The specific details of the fit between the balance block 200 and the housing 1 have been described above and will not be repeated here.

[0119] The balance block system provided in this application embodiment is easy to use and can quickly adjust the height of the balance block 200. It can also achieve height adjustment without stopping the equipment or disassembling the balance block.
