[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 9 As shown, the present embodiment is a hollowing device for the surface of an aluminum gusset plate which is capable of eliminating burrs on the edges of the hollowed-out parts. The main structure includes a hollowing stamping assembly 100, a movable hollowing die 200 and a hollowing stamping base 300. The movable hollowing die 200 is arranged on the hollowing stamping base 300. The hollowing stamping assembly 100 is arranged above the hollowing stamping base 300. The movable hollowing die 200 is slidably connected to the hollowing stamping base 300. When in use, the present embodiment places the aluminum gusset plate on the corresponding movable hollowing die 200, and the hollowing stamping assembly 100 stamps the aluminum gusset plate to squeeze out excess material from the movable hollowing die 200. The hollowing stamping assembly 100 realizes the hollowing of the aluminum gusset plate by cooperating with the movable hollowing die 200.

[0022] Compared with a fixed stamping machine, the mobile hollowing mold 200 proposed in this embodiment can slide on the hollow stamping base 300. When the mobile hollowing mold 200 slides, it drives the aluminum gusset plate to slide on the hollow stamping base 300, changing the relative position with the hollow stamping assembly 100. After the hollow stamping assembly 100 completes a stamping, the mobile hollowing mold 200 will drive the aluminum gusset plate to move a distance, and move the hollowed-out part away from under the hollow stamping assembly 100, so that the hollow stamping assembly 100 can perform the next stamping and hollowing. There is no need to manually carry the aluminum gusset plate, which improves work efficiency. It is suitable for aluminum gusset plates that need to be hollowed out in large quantities of the same shape.

[0023] The hollow stamping assembly 100 proposed in this embodiment includes a stamping block 103, on which a swing rod 105 is provided, and the swing rod 105 is located on the side of the stamping block 103, and the swing rod 105 is rotatably connected to the stamping block 103, and the angle opening direction between the swing rod 105 and the stamping block 103 is upward, and a grinding roller 107 is provided on the end of the swing rod 105 away from the stamping block 103, and the grinding roller 107 is rotatably connected to the swing rod 105. Configured to grind the burrs on the hollow edge, the hollow stamping assembly 100 proposed in this embodiment includes a stamping block 103, and the stamping block 103 is used to stamp the aluminum gusset plate. Compared with the existing stamping head, the stamping block 103 is provided with a rotating swing rod 105, and the swing rod 105 is provided with a rotating grinding roller 107. When the stamping block 103 stamps the aluminum gusset plate, the grinding roller 107 contacts the edge of the hollow position, and the grinding roller 107 is squeezed and rubbed with the edge, thereby removing defects such as burrs on the hollow edge.

[0024] When this embodiment is in use, the hollow stamping assembly 100 drives the stamping block 103 to move downward and contact the aluminum gusset plate to stamp and hollow it, and at the same time drives the swing rod 105 and the grinding roller 107 to pass through the aluminum gusset plate. After the swing rod 105 passes through the aluminum gusset plate, it drives the grinding roller 107 to rotate downward. After the stamping and hollowing is completed, the stamping block 103 rises. During the rising process of the stamping block 103, the grinding roller 107 contacts the edge of the hollow position. The stamping block 103 applies an upward lifting force to the swing rod 105 and the grinding roller 107, so that the grinding roller 107 is squeezed with the edge of the hollow position. The friction force generated pushes the grinding roller 107 to rotate relative to the swing rod 105, thereby grinding the burrs on the edge of the hollow position, reducing the subsequent work steps.

[0025] The side of the stamping block 103 proposed in this embodiment is provided with a side groove 104, the swing arm 105 and the grinding roller 107 are arranged inside the side groove 104, when the swing arm 105 is rotated to a vertical state, the grinding roller 107 is in the side groove 104, and the swing arm 105 is also provided with a torsion spring 106, the two ends of the torsion spring 106 are respectively connected to the swing arm 105 and the stamping block 103, so that the swing arm 105 and the grinding roller 107 can be retracted into the side groove 104, and the swing arm 105 and the grinding roller 107 do not exceed the surface of the stamping block 103 when they are in the side groove 104, and at the same time, the swing arm 105 is connected to the stamping block 103 through the torsion spring 106, so that the swing arm 105 always maintains a fixed angle without being subjected to external force.

[0026] When the punching block 103 is in use, the swing rod 105 and the grinding roller 107 on the punching block 103 move downward synchronously to punch the aluminum gusset plate. When the punching block 103 passes through the aluminum gusset plate, the swing rod 105 is in extrusion contact with the aluminum gusset plate, and the thrust generated pushes the swing rod 105 to rotate on the punching block 103, and at the same time applies a torsional torque to the torsion spring 106. When the swing rod 105 and the grinding roller 107 rotate to be retracted into the side groove 104, the punching The pressing block 103 can pass through the aluminum gusset plate. After the punching block 103 passes through the aluminum gusset plate, the torsional torque in the torsion spring 106 is released, and the swing rod 105 and the grinding roller 107 rotate out of the side groove 104 and return to their original positions; then the punching block 103 rises upward, and the swing rod 105 and the grinding roller 107 are lifted synchronously. At this time, the grinding roller 107 is located outside the side groove 104, so the grinding roller 107 can contact the edge of the hollow position, thereby realizing the grinding of the burrs on the edge of the hollow position.

[0027] This embodiment is provided with a swing rod 105 and a grinding roller 107 that can be retracted into the side groove 104, which can prevent the swing rod 105 and the grinding roller 107 from interfering with the stamping work of the stamping block 103 and ensure that the shape punched out by the stamping block 103 remains accurate.

[0028] The hollow stamping assembly 100 proposed in this embodiment includes a stamping base 101, a stamping telescopic rod 102 and a stamping block 103. The stamping block 103 is connected to the stamping base 101 through the stamping telescopic rod 102. The stamping telescopic rod 102 is configured to drive the stamping block 103 to rise and fall relative to the stamping base 101. When punching and hollowing out, the stamping telescopic rod 102 first extends out from the stamping base 101, driving the stamping block 103 to move downward to punch and hollow out the aluminum gusset plate. After the hollowing out is completed, the stamping telescopic rod 102 retracts into the stamping base 101, thereby driving the stamping block 103 to move upward away from the aluminum gusset plate.

[0029] The mobile hollowing mold 200 proposed in this embodiment includes a mold pad 201, and the mold pad 201 is slidably set on the hollow stamping base 300. The stamping base 101 is located above the mold pad 201. When this embodiment is in use, the corresponding mold pad 201 is selected according to the required hollow shape, and the aluminum gusset plate is fixed on the mold pad 201. Then the mold pad 201 drives the aluminum gusset plate to pass under the stamping block 103. The stamping block 103 punches and hollows out multiple positions on the aluminum gusset plate in turn, which improves work efficiency.

[0030] In this embodiment, the mold pad 201 proposed in this embodiment is provided with a punching hole 203, and the punching hole 203 corresponds to the position of the punching block 103. A plurality of the punching holes 203 are arranged along a linear array on the mold pad 201, and the hollow stamping base 300 is provided with a hollow groove 301 and a moving drive assembly 303. The mold pad 201 is slidably arranged on the hollow groove 301, and the moving drive assembly 303 is configured to drive the mold pad 201 to move on the hollow groove 301.

[0031] When the punching block 103 proposed in this embodiment punches and hollows out the aluminum gusset plate, excess material squeezed out falls into the hollowing groove 301 through the punching hole 203, so as to avoid material adhesion and incomplete hollowing. At the same time, a moving drive component 303 is arranged on the hollowing punching base 300 to drive the mold pad 201 to move on the hollowing groove 301. Whenever the punching block 103 completes a punching and hollowing, the moving drive component 303 drives the mold pad 201 to move once. Each time the moving drive component 303 drives the mold pad 201 to move, the punching hole 203 is moved to the bottom of the punching block 103, so that the punching block 103 can perform punching and hollowing.

[0032] In this embodiment, the plurality of punching holes 203 are sequentially matched with the punching blocks 103 by moving the driving assembly 303 and the die pad 201, so that a plurality of identical hollowing holes can be made on an aluminum gusset plate.

[0033] The mold pad 201 proposed in this embodiment is provided with support rods 204, and multiple support rods 204 are symmetrically arranged on both sides of the mold pad 201. Symmetrical slide rails 302 are symmetrically arranged on both sides of the hollow stamping base 300. The support rods 204 are arranged in the symmetrical slide rails 302, and the support rods 204 are slidably connected to the symmetrical slide rails 302. When the mobile driving component 303 drives the mold pad 201 to slide on the hollow groove 301, the support rods 204 slide in the symmetrical slide rails 302, and the mold pad 201 is limited bidirectionally and symmetrically to prevent the mold pad 201 from being offset in position on the hollow groove 301, resulting in inaccurate hollow position.

[0034] The mobile driving assembly 303 proposed in this embodiment includes a spur gear 306, and a gear support 308 is arranged on the hollow stamping base 300. The spur gear 306 is arranged on the gear support 308, and the spur gear 306 is rotatably connected with the gear support 308. A spur rack 202 is provided on the bottom surface of the mobile hollow mold 200, and the spur rack 202 is fixedly connected to the mobile hollow mold 200. The spur rack 202 is meshed with the spur gear 306, and the gear support 308 is configured to drive the spur rack 202 to move when rotating. This embodiment realizes power transmission by arranging the spur rack 202 and the spur gear 306 to mesh with each other.

[0035] When this embodiment is in use, the spur gear 306 rotates on the gear support 308 to drive the spur rack 202 meshing with it to move, thereby pushing the mold pad 201 fixedly connected to the spur rack 202. The conversion of torque is completed through the meshing of the punching hole 203 and the spur gear 306. The moving direction of the mold pad 201 can be changed by changing the rotation direction of the spur gear 306.

[0036] The mobile drive component 303 proposed in this embodiment also includes a servo motor 304 and a motor shaft 305. The servo motor 304 is arranged on the hollow stamping base 300. The motor shaft 305 is rotatably connected to the servo motor 304. The spur gear 306 is fixedly connected to the motor shaft 305. The servo motor 304 is configured to drive the rotation of the spur gear 306 through the motor shaft 305. The spur gear 306 proposed in this embodiment is driven by the servo motor 304. When in use, the motor shaft 305 can accurately control the rotation angle and rotation speed of the spur gear 306. After the stamping block 103 completes a stamping, the servo motor 304 drives the mold pad 201 to move a specific distance, so that the position of the stamping hole 203 accurately corresponds to the position of the stamping block 103.

[0037] The hollow stamping base 300 proposed in this embodiment is provided with a motor protection shell 307, and the motor protection shell 307 is located above the servo motor 304. The servo motor 304 is arranged inside the motor protection shell 307. The motor protection shell 307 protects the servo motor 304. After the excess material squeezed out by the punching block 103 during punching and hollowing falls down, the motor protection shell 307 isolates the excess material from the servo motor 304 to prevent the excess material from affecting the operation of the servo motor 304.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0039] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
