Description
Technical field
It the utility model is related to metal can body forming machine field, and in particular to a kind of jumper bar of metal can body forming machine
Structure.
Background technology
Metal can, such as pop can, generally there are two kinds of aluminum and irony, its structure is made up of can body and lid two parts,
Wherein can body is formed by metal stretching mostly.Body forming machine, also known as stretching-machine, it is important in metal can production set
It is standby, directly affect the quality of product.Body forming machine, generally by can body and tank bottom shaped device（Mould）, enter cup mechanism, go out
Tank mechanism, blank body, jumper bar and a few part compositions of jumper bar drive mechanism.Wherein, body forming device（Mould）For stretching
Can body, enter cup mechanism be used for convey stretching before tank base（The cup shell of pre-stretching）, Chu Guan mechanisms be used for stretch after discharging and
Tank body is exported, and blank body is provided when can body stretches for compressing tank base edge, jumper bar and jumper bar drive mechanism when stretching
Punching stroke.
In body forming machine, jumper bar is a strength member, at work, be from jumper bar with punch-head assembly make high speed toward
Multiple motion.Existing jumper bar includes：Jumper bar body, drift pad, punch-head assembly and drift screw；The punch-head assembly is to be arranged
In the front end of jumper bar body, the center of punch-head assembly wears the drift screw, afterbody and the jumper bar sheet of drift screw towards jumper bar
Body is threadedly coupled.Because punch-head assembly is shaping dies, generally provided by client, and outside dimension in the punch-head assembly of different clients
And punch-head assembly length is different.Therefore, the body forming machine of even same model is also required to produce various sizes of
Jumper bar and the punch-head assembly of different clients match.This aspect causes the manufacturing cost of jumper bar to rise, and management difficulty increases；It is another
Aspect also rises the use cost of client, needs to order the jumper bar of different size when remodeling, and need more when remodeling
Change whole jumper bar, it is a comparatively laborious thing, it is necessary to readjust precision to change jumper bar, is wasted time and energy.
The content of the invention
The utility model purpose is to provide a kind of jumper bar structure of metal can body forming machine, to solve prior art presence
Need standby various various sizes of jumper bars to match with punch-head assembly, stock amount is big, jumper bar manufacturing cost is increased, management
The problem of difficulty increases and client's use cost rises.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of jumper bar of metal can body forming machine
Structure, including jumper bar body, punch-head assembly and drift screw, in addition to a jumper bar adaptor, the jumper bar adaptor is located at punching
Between the front end of bar body and punch-head assembly, the drift screw along jumper bar axially across punch-head assembly, jumper bar adaptor after
It is threadedly coupled, i.e., lock onto punch-head assembly, jumper bar adaptor on jumper bar body front end simultaneously through drift screw with jumper bar body.
In such scheme, the jumper bar body is provided with middle cavity, and jumper bar filler is provided with middle cavity.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
The utility model jumper bar body can standardize, and be advantageous to produce in enormous quantities, reduce price, shorten delivery cycle,
Client also need to only change corresponding jumper bar adaptor when changing drift, without jumper bar body is removed, greatly save work
Amount, shortens the operating time.
Brief description of the drawings
Fig. 1 is the structure complete section schematic diagram of the utility model embodiment；
In the figures above：1st, jumper bar body；2nd, punch-head assembly；3rd, drift screw；4th, jumper bar adaptor；5th, jumper bar is filled
Thing；6th, jumper bar filler；7th, jumper bar filler；8th, jumper bar filler.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment：It is shown in Figure 1：
A kind of jumper bar structure of metal can body forming machine, including jumper bar body 1, punch-head assembly 2 and drift screw 3,
Mainly also include a jumper bar adaptor 4, the jumper bar adaptor 4 is between the front end of jumper bar body 1 and punch-head assembly 2, institute
State drift screw 3 to be threadedly coupled with jumper bar body 1 axially across after punch-head assembly 2, jumper bar adaptor 4 along jumper bar, i.e., through punching
Punch-head assembly 2, jumper bar adaptor 4 are lock onto on the front end of jumper bar body 1 by head screw 3 simultaneously.
The jumper bar body 1 is provided with middle cavity, and jumper bar filler 5,6,7,8 is provided with middle cavity.
The jumper bar body 1 that the present embodiment makes production requirement higher standardizes, and uniform specification of getting ready the goods, can be mass-produced, and
Outside dimension and punch-head assembly length in the punch-head assembly according to client is only needed to configure jumper bar adaptor 4, and jumper bar adaptor 4 is given birth to
Production difficulty is relatively low, and speed of production is also fast, therefore without largely get ready the goods, manufacturing cost is significantly reduced, reduces management difficulty.It is another
Aspect, when changing punch-head assembly 2 in the use of client, also only need to change jumper bar adaptor 4, without jumper bar body 1 is torn open
Remove, greatly save workload, shorten the time of remodeling.
For above-described embodiment only to illustrate technical concept of the present utility model and spy and feature, its object is to allow be familiar with this
The personage of technology can understand content of the present utility model and implement according to this, and protection model of the present utility model can not be limited with this
Enclose.All equivalent change or modifications made according to the utility model Spirit Essence, it should all cover in protection model of the present utility model
Within enclosing.
