Abstract
The present invention relates to stamping dies to demould field, specially a kind of stamping die with replacement and automatic demoulding, including workbench, suspension, hydraulic cylinder, upper die and lower die；It is connected through a screw thread between the lower die and workbench；The lower die is internally provided with stripper apparatus, and the stripper apparatus includes top plate, spring and the loading plate moved along lower die inner vertical direction.The present invention, which passes through, is arranged detachable lower die, and the spring of changeable type is arranged inside lower die；Solve it is existing when spring breaking down cannot provide elastic force, part can not just be taken out, along with spring cannot be replaced, so whole set of die will be dropped, the problem of causing the waste of resource and increase production cost；In addition of the invention easily operated and maintenance and repair, structure is simple, and cost is relatively low.
Description
Technical field
The present invention relates to stamping dies to demould field, specially a kind of stamping die with replacement and automatic demoulding
Tool.
Background technique
Stamping die is that material (metal or nonmetallic) is processed into the one of part (or semi-finished product) in Cold Press Working
Kind of special process device, referred to as cold punching die, using relatively broad in mold manufacture, but existing stamping die is being rushed
It after the completion of pressure, since the pressure that part is subject to is larger, is often bonded in lower die, needs manually to be drawn off, increase labor
Fatigue resistance；
In existing stamping die can have pickoff, pickoff be by spring connect mandril group
At being compressed using spring when punching press, the elastic force of spring ejects part after punching press；But such words spring is easily damaged,
When spring breaking down cannot provide elastic force, part can not just be taken out, and encounter such case, whole because spring cannot be replaced
Mold will be dropped, and caused the waste of resource and increased production cost.
Summary of the invention
It is existing to solve the purpose of the present invention is to provide a kind of stamping die with replacement and automatic demoulding
Because spring be easily damaged cannot replace and caused by the wasting of resources and increase production cost the problem of.
To achieve the goals above, technical scheme is as follows：
A kind of stamping die with replacement and automatic demoulding, including workbench are provided on the workbench outstanding
Frame is provided with hydraulic cylinder on the suspension, and the hydraulic cylinder is connected with upper mold, and the workbench is provided with compatible with upper mold
Lower die；
It is connected through a screw thread between the lower die and workbench；The lower die is internally provided with stripper apparatus, the demoulding
Device include can along inside lower die can the top plate that moves of vertical direction, the bottom of the top plate is connected with several springs,
Several lower spring ends are both connected on loading plate, and the loading plate setting is in workbench and is located inside lower die.
As a further improvement of the present invention, the upper surface of the top plate is flushed with the work bottom surface in lower die.
As a further improvement of the present invention, the surrounding of the lower die is provided with several No.1 threaded holes (5a), described
Be provided on workbench with several one-to-one No. two threaded holes of several No.1 threaded holes, several No.1 threaded holes with
Several No. two threaded holes are correspondingly connected with by bolt.
As a further improvement of the present invention, the connection that several springs and top plate, loading plate are buckled by screw respectively
Mode connects.
As a further improvement of the present invention, several springs are compressed spring.
The beneficial effects of the invention are as follows：
The present invention, which passes through, is arranged detachable lower die, and the spring of changeable type is arranged inside lower die；It solves
It is existing that when spring breaking down cannot provide elastic force, part can not just be taken out, along with the spring in this spline structure cannot be replaced, institute
The problem of will being dropped with whole set of die, causing the waste of resource and increase production cost；In addition of the invention easily operated
And maintenance and repair, structure is simple, and cost is relatively low.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples：
Fig. 1 is schematic view of the front view of the invention；
Fig. 2 is the A-A schematic cross-sectional view of Fig. 1；
Fig. 3 is the I partial enlarged view of Fig. 1；
Fig. 4 is the configuration schematic diagram of lower die in the present invention.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
It closes attached drawing and the present invention is further described in embodiment.
As shown in Figures 1 to 4, a kind of stamping die with replacement and automatic demoulding, including workbench 1, it is described
It is provided with suspension 2 on workbench 1, hydraulic cylinder 3 is provided on the suspension 2, the hydraulic cylinder 3 is connected with upper mold 4, the work
Platform 1 is provided with lower die 5 compatible with upper mold 4.
It is connected through a screw thread between the lower die 5 and workbench 1；The lower die 5 is internally provided with stripper apparatus, described de-
Mold device include can along inside lower die 5 can the top plate 6 that moves of vertical direction, the bottom of the top plate 6 is connected with several
Spring 7, several described springs 7 are compressed spring, and it is in order to prevent when one of them that multiple reasons, which is arranged, in the spring 7
Spring 7 damages, and still is able to provide elastic force there are also remaining spring 7, part is ejected；Several described 7 lower ends of spring are all connected with
On loading plate 8, the setting of loading plate 8 is in workbench 1 and is located inside lower die 5.
The 5 outside left and right sides of the lower die is respectively opened there are two No.1 threaded hole 5a, on the workbench 1 with have No.1 spiral shell
It is provided with No. two threaded holes 1a, the No.1 threaded hole 5a and No. two threaded hole 1a on the one-to-one position pit 5a and passes through spiral shell
Bolt 9 is correspondingly connected with, in order to reduce bolt 9 and abrasion, be provided with washer 10 between the bolt 9 and No.1 threaded hole 5a.
When spring breaking down, in order to facilitate the replacement of spring 7, several described springs 7 pass through with top plate 6, loading plate 8
The connection type connection of screw buckle.
Application method of the invention：
As shown in Figure 1, start when, top plate 6 is flushed with the work bottom surface in lower die 5, when needing to stamp plate, spring by
To pressure, compression will do it, after the completion of punching press, upper mold 4 rises, and top plate 6 will receive elastic force rising and part is ejected, and works as mold
After a period of work, spring damages, but because the reason of multiple spring 7 are arranged, top plate 6 still will receive bullet
Power, when the spring 7 of damage reaches certain amount；
As shown in figure 4, removing bolt 9, lower die 5 is taken away, takes out the stripper apparatus being located inside lower die 5, and because bullet
Spring 7 is to connect in such a way that screw snaps connection, therefore be easy to replace spring with top plate 6, loading plate 8, so
Afterwards, lower die 5 is installed again.Easily operated and maintenance and repair of the invention, structure is simple, and cost is relatively low；Avoid because
Existing middle spring cannot be replaced, and entire mold will abandon to cause the problem of the production cost increases.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
Improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent
Object defines.
