The technical purpose of the utility model is achieved in that
A kind of spacing block set stamping die of angle grinder protective cover, it is characterised in that: including upper die and lower die, upper mold is by liquid
Cylinder pressure driving is simultaneously positioned opposite with lower die, and lower die is installed on the base by guide post, and uprighting spring is arranged on guide post；Lower die
Top is formed with the boss of a hexagon, and the center of boss offers one for being inserted into the circular heavy of protective cover neck
Slot, deep gouge inside form mold core；The each edge of boss is designed with a punching mechanism along outside, the punching mechanism include column,
Mandril, swinging block and reset spring offer the vertical through-hole being adapted with column in lower die, are formed on the inside of the upper end of column
Inclined-plane, the lower end of column are fixed on the base after passing through vertical through-hole；It is offered on boss from toward outer side edges edge and penetrates into deep gouge
Horizontal through hole, mandril is slidably mounted in horizontal through hole, and mandril inner end is formed with the top for punching press spacing block set, mould
It is offered on core for the molding die hole of spacing block set, mandril outer end is formed with the inclined-plane matched with column inclined-plane；Swinging block is logical
It crosses support and the first pin shaft is hinged on lower die top surface, the both sides of swinging block extend to mandril outer end by side plate, and side plate prolongs
It is hinged by the second pin shaft and mandril outer end to stretch end, the side plate of two sides also passes through the hinged axis connection of third, one end of reset spring
The edge of lower die is fixed on by fixed plate, the other end is connected on the second articulated shaft after bypassing third articulated shaft.
The top surface of the boss is equipped with the backer of arc, and the both ends of backer are used to position two radial edges of protective cover,
Complete circle is formed after backer and protective cover splicing.
After the utility model has the beneficial effect that the utility model positions protective cover, multiple punching presses can be passed through
Mechanism once stamps out multiple spacing block sets in neck, and stable product quality, work efficiency is high.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model.
Fig. 2 is the overlooking structure diagram of lower die.
Fig. 3 is the schematic perspective view of protective cover.
Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the spacing block set stamping die of a kind of angle grinder protective cover provided by the utility model, including
Upper mold 1 and lower die 15, upper mold is positioned opposite with lower die, and upper mold can opposite lower die oscilaltion under the driving of hydraulic cylinder.Lower die
Bottom surface offer several pilot holes, pilot hole is mounted on pedestal 17 by guide post 18, and uprighting spring 19 is arranged on guide post.
The boss 2 of a hexagon is formed at the top of lower die, the center of boss offers one for being inserted into the circle of protective cover neck
The deep gouge of shape, deep gouge inside form mold core 4.The each edge of boss is designed with the (punching there are six altogether of a punching mechanism along outside
Press mechanism).
The punching mechanism includes column 16, mandril 7, swinging block and reset spring 11, is offered in lower die and column phase
The vertical through-hole adapted to, the upper end inside of column are formed with inclined-plane, and the lower end of column is fixed on the base after passing through vertical through-hole.It is convex
It is offered on platform from toward outer side edges, along the horizontal through hole 20 for penetrating into deep gouge, mandril is slidably mounted in horizontal through hole, top
Bar inner end is formed with the top 6 for punching press spacing block set, is offered on mold core for the molding die hole 5 of spacing block set, outside mandril
End is formed with the inclined-plane matched with column inclined-plane.Swinging block is hinged on lower die top surface by support 13 and the first pin shaft 12, puts
The both sides of motion block extend to mandril outer end by side plate 9, and the elongated end of side plate is hinged by the second pin shaft 8 and mandril outer end, and two
The side plate of side also passes through the connection of third articulated shaft 10, and third articulated shaft 10 is located at the rear side of column, and one end of reset spring passes through
Fixed plate 14 is fixed on the edge of lower die, and the other end is connected on the second articulated shaft after bypassing third articulated shaft.
The top surface of the boss is equipped with the backer 3 of arc, and the both ends of backer are used to position two radial edges of protective cover,
Complete circle is formed after backer and protective cover splicing.
The working principle of the utility model is: protective cover is inverted by worker, neck is inserted into groove, two of protective cover
Radial edges are resisted against the both ends of arc backer.Then start hydraulic cylinder, upper mold pushes, by protective cover, boss and lower die to
Push, lower die, boss move down under the guidance of guide post, and column remains stationary, mandril under the action of inclined-plane, on one side under
Drop, overcomes spring force to move inward on one side, and the top of mandril inner end squeezes the neck of protective cover, and the region that is squeezed is deformed inward,
Spacing block set is formed in die hole.After the completion of punching press, hydraulic cylinder resets, and upper mold rises, and lower die and boss reset, and mandril is resetting
It under the active force of spring, bounces back while rising, after lower die resets completely, worker can take out protective cover.
The above is only the preferred embodiment of the present invention, and for those skilled in the art, this is practical new
Type can have various modifications and variations.Within the spirit and principle of the utility model, it is made it is any modification, equally replace
It changes, improve, should be included within the scope of protection of this utility model.
