Abstract
The invention discloses a kind of pipe indent processing molds, comprising: upper half tube core and lower half tube core are formed by same die separation, and the cut surface of upper half tube core and lower half tube core is obliquely installed, and the left end of cut surface is higher than right end, offer multiple grooves at the top of upper half tube core；Cross bar, both ends are fixed in lower template through upright bar respectively, and the right side of cross bar and the left side of upper half tube core are fixed；Holding rod, one end and the left side of lower half tube core are fixed；Work as hollow pipe, when covering outside the upper half tube core and lower half tube core of closure and being placed in lower template, passes through formed punch, press hollow pipe top surface on position corresponding with groove, hollow pipe top surface can generate indent, holding rod and lower half tube core towards after left extraction, and hollow pipe can take out to the right from upper half tube core.The beneficial effect that the present invention has simple structure and convenient processing, reduces product cost and weight.
Description
Technical field
The present invention relates to a kind of pipe indent processing molds.
Background technique
High-grade chair, is provided with the headrest, and the height of the headrest can be adjusted up and down according to the height of human body, in order to compared with
The good fixation headrest, needs support rod, multiple indents is opened up on support rod, block indent by fixture block, thus fixing head
The position of pad, in the prior art, support rod are process using solid core metallic rod, and indent is opened up in metallic rod, existing for
The disadvantage is that solid core metallic rod weight ratio is heavier, when processing, the press tonnage needed is big.
Summary of the invention
The present invention can be used to process hollow pipe, by hollow pipe according to the above deficiency, provide a kind of pipe indent processing mold
Support rod as the fixed headrest.
The technical scheme is that
A kind of pipe indent processing mold, characterized in that include:
Upper half tube core and lower half tube core, are formed by same die separation, and the cut surface of upper half tube core and lower half tube core is obliquely installed,
The left end of cut surface is higher than right end, offers multiple grooves at the top of upper half tube core；
Cross bar, both ends are fixed in lower template through upright bar respectively, and the right side of cross bar and the left side of upper half tube core are fixed；
Holding rod, one end and the left side of lower half tube core are fixed；
Work as hollow pipe, when covering outside the upper half tube core and lower half tube core of closure and being placed in lower template, by formed punch, with it is recessed
Press hollow pipe top surface on the corresponding position of slot, and hollow pipe top surface can generate indent, holding rod and lower half tube core towards after left extraction,
Hollow pipe can take out to the right from upper half tube core.
It should be noted that if tube core is not cut into upper half tube core and lower half tube core, when extruding indent on hollow pipe
When, tube core can not be extracted out.The present invention just easily can first be extracted lower half tube core out using the cut surface being obliquely installed, finally
Hollow pipe is extracted out.
In use, the present invention can be fixed on press, formed punch is directly anchored to below upper die of punching press plate.
Mobile lower half tube core is positioned for convenience, the holding rod is provided with limited block, when the upper half
When tube core and lower half tube core are closed, limited block can touch the cross bar or upright bar.
In order to increase contact area, while facilitating positioning, the lower template offers the circular arc indent coincideing with hollow pipe.
Further include scale bar in order to find the position of groove accurately, be fixed on the side of upper half tube core and lower half tube core,
Label impression corresponding with groove is offered on scale bar, when the formed punch alignment mark impression, formed punch can be also aligned
The groove.
Faster processing method, the formed punch have multiple, and multiple formed punches are fixed on cope plate by the spacing of groove
Lower section.
The beneficial effect that the present invention has simple structure and convenient processing, reduces product cost and weight.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention.
Specific embodiment
Now in conjunction with attached drawing, the present invention is further illustrated:
As shown, a kind of pipe indent processing mold, characterized in that include:
Upper half tube core 32 and lower half tube core 31, are formed by same die separation, the cut surface of upper half tube core 32 and lower half tube core 31
34 are obliquely installed, and the left end of cut surface 34 is higher than right end, and the top of upper half tube core 32 offers multiple grooves 33；
Cross bar 51, both ends are fixed in lower template 1 through upright bar 52 respectively, the right side of cross bar 51 and the left end of upper half tube core 32
Face is fixed；
Holding rod 41, one end and the left side of lower half tube core 31 are fixed；
When hollow pipe 2, when covering outside the upper half tube core 32 and lower half tube core 31 of closure and being placed in lower template 1, pass through formed punch
6, press 2 top surface of hollow pipe on position corresponding with groove 33, and 2 top surface of hollow pipe can generate indent 21, and holding rod 41 is under
Towards after left extraction, hollow pipe 2 can take out to the right half tube core 31 from upper half tube core 32.
Holding rod 41 is provided with limited block 42, and when upper half tube core 32 and the closure of lower half tube core 31, limited block 42 can be touched
Cross bar 51 or upright bar 52.
Lower template 1 offers the circular arc indent coincideing with hollow pipe 2.
Further include scale bar, be fixed on the side of upper half tube core 32 and lower half tube core 31, offered on scale bar with it is recessed
The corresponding label impression of slot 33, when 6 alignment mark impression of formed punch, formed punch 6 also can alignment indentation 33.
Formed punch 6 has multiple, and multiple formed punches 6 are fixed on the lower section of cope plate by the spacing of groove 33.
