Referring to fig. 4, after the residue 3211 is extruded from the sealing hose 51, the residue falls down to the edge of the upper port of the extrusion hole 81, in order to reduce the residue 3211 remaining at the edge of the upper port of the extrusion hole 81, a guide inclined plane 82 for guiding the residue 3211 to fall down to the extrusion plate 8 is disposed at the upper surface of the extrusion plate 8, the guide inclined plane 82 is distributed around the edge of the upper port of the extrusion hole 81, and the guide inclined plane 82 inclines from the extrusion hole 81 to the edge of the extrusion plate 8, so that when the residue 3211 falls on the upper surface of the extrusion plate 8, the residue 3211 slides along the guide inclined plane 82 to the edge of the extrusion plate 8, and the residue 3211 remaining at the edge of the upper port of the extrusion hole 81 is greatly reduced, so that the subsequent residue 3211 can fall down more smoothly.
Referring to fig. 3 and 4, a gap is formed between the edge of the extrusion plate 8 and the side wall of the accommodating space 311, a plurality of connecting rods 83 are arranged in the gap, the connecting rods 83 are made of stainless steel, the two connecting rods 83 are vertically arranged, the two connecting rods 83 are symmetrically distributed, the upper ends of the connecting rods 83 are welded with the edge of the extrusion plate 8, the lower ends of the connecting rods 83 penetrate through the linkage plate 73 and are welded at the bottom of the through groove 313, and the connecting rods 83 are slidably connected with the linkage plate 73; the excess material 3211 that slides to the edge of the upper surface of the extrusion plate 8 can drop downward from the gap, so that the excess material 3211 on the extrusion plate 8 can be effectively prevented from being accumulated more.
Referring to fig. 4, in this embodiment, because there are a plurality of key holes 41 (refer to fig. 1A) on the aluminum shell 4 (refer to fig. 1A), there are a plurality of stamping holes 321, and one suction pipe 5 and one sealing hose 51 can only suck the remainder 3211 in one stamping hole 321, therefore, each stamping hole 321 is provided with a group of suction pipes 5 and sealing hoses 51, correspondingly, the driving assembly 7 is also provided at each group of suction pipes 5 and sealing hoses 51, but in order to save the driving member 74, a plurality of linkage plates 73 in a plurality of groups of driving assemblies 7 are welded to form one large linkage plate 73, at this time, only one driving member 74 needs to be installed, so as to achieve the purpose of simultaneously driving a plurality of groups of suction pipes 5 and sealing hoses 51 to move up and down.
Referring to fig. 4, in order to clean the excess material 3211 at the through groove 313, the upper surface of the linkage plate 73 is convex upward, so that the excess material 3211 falling on the linkage plate 73 can slide toward the edge of the linkage plate 73, and a gap also exists between the edge of the linkage plate 73 and the side wall of the through groove 313, so that the excess material 3211 can finally slide into the through groove 313, and at this time, the worker can clean the excess material 3211 at the through groove 313.
The implementation principle of the embodiment is as follows: when the aluminum shell 4 is punched, firstly, the aluminum shell 4 needs to be sleeved on the lower die assembly 32, then the upper die assembly 2 is driven to move downwards at a high speed, so that the upper die 22 and the lower die assembly 32 complete die assembly, at the moment, the press key hole 41 is punched on the upper side surface of the aluminum shell 4 by the press rod 221, the punched excess material 3211 is plugged into the punching hole 321, then the upper die assembly 2 moves upwards again to perform die opening, a worker takes out the punched aluminum shell 4 after die opening, and finally the excess material 3211 in the punching hole 321 is cleaned.
When cleaning the remainder 3211 in the punching hole 321, firstly, the driving member 74 is started, the piston rod of the driving member 74 pushes the linkage plate 73 upward, so that the linkage plate 73 pushes the suction pipe 5 and the sealing hose 51 upward through the linkage rod 72 and the fixing ring 71, until the upper end port of the sealing hose 51 abuts against the edge of the lower end port of the punching hole 321, at this time, the suction member 6 generates suction in the suction pipe 5, so that the remainder 3211 is sucked into the sealing hose 51 by the suction pipe 5, then the piston rod of the driving member 74 contracts, the piston rod pulls the linkage plate 73 downward, so that the linkage plate 73 pulls the suction pipe 5 and the sealing hose 51 downward through the linkage rod 72 and the fixing ring 71, the sealing hose 51 enters the accommodating space 311, and at the same time, the sealing hose 51 slides in the extruding hole 81, so that the hole wall of the extruding hole 81 extrudes the remainder 3211 in the sealing hose 51 upward, the excess 3211 falls off the sealing hose 51 and then falls on the upper surface of the extrusion plate 8, slides down the upper surface of the extrusion plate 8 along the guide inclined plane 82, falls on the upper surface of the linkage plate 73, and finally slides down to the bottom of the through groove 313 from the upper surface of the linkage plate 73, and when more excess 3211 is left at the bottom of the through groove 313, the excess 3211 can be poked out from openings at two ends of the through groove 313 by using a tool.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
