Abstract
The utility model discloses an ejection piece device for a cylinder, comprising the cylinder, a support frame (3) and an installation plate (4), wherein the cylinder is composed of a piston rod (2) and a cylinder body (1); the cross section of one end which is in nesting fit with the cylinder body (1), of the piston rod (2), is regular-polygonal; the outer end of the piston rod (2) is cylindrical; the end part of the outer end of the piston rod (2) is fixedly connected with the middle of the installation plate (4), and the piston rod (2) is vertical to the installation plate (4); and the both ends of the installation plate (4) are fixed with the support frame (3). The ejection piece device disclosed by the utility model adopts a non-rotating cylinder structure, and has no need to add a guide column and a guide sleeve to prevent rotation, so that the whole ejection piece device is simpler in structure, the error rate of a bench worker during installation is reduced, and the efficiency of the bench worker is increased, thus increasing the production efficiency of a mould and saving the cost of the mould; and moreover, the ejection piece device is wider in application range.
Description
Technical field
The utility model relates to a kind of cylinder head part device, be used for mould pickup, send part etc.
Background technology
Exist various plates in the automobile panel, these plates need to pass through Mould Machining, and a plate generally will divide multiple working procedure processing, comprising: drawing and moulding, side cut, punching, flange moulding etc.In the complete rear order of drawing and moulding, the unnecessary part in process complementary surface border that needs to do in the time of will drawing is cut away, because all need on every side to cut edge, so there is not vacant space pickup.In addition, when plate is larger (as: rear floor, front floor, top cover etc.), directly pickup, the one, plate is heavier; The 2nd, there is certain package power in plate at mould.At this moment, need to be by external force with plate from mold ejection, and then pickup.The head part device that cylinder is and front utilization is more, in addition, cylinder is except being used for pickup, and other utilizations are also more extensive in die industry.
And front, the piston rod cross section of the cylinder that extensively uses in the die industry is circular, can produce circumferential rotation, drives simultaneously bracing frame and rotates, and causes normally pickup of mould, and impact is produced continuously.So, existing cylinder head part device is except cylinder body, piston rod, piston rod installing plate and bracing frame, each side added a guide pillars and bushes at cylinder body, guide pin bushing installing plate of cylinder body upper end suit, guide pillar is fixed by piston rod installing plate and piston rod, and guide pin bushing is fixed by guide pin bushing installing plate and cylinder body, and guide pillars and bushes cooperates, circumferentially spacing to piston rod, thus play the effect of anti-rotation.Existing cylinder head part device has the following disadvantages:
1) complicated integral structure, error rate was higher when pincers worker was installed, and had reduced the production efficiency of whole mould.
2) need the die space of installation larger, reduced its scope of application.
3) increased the manufacturing cost of head part device.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of not rotary cylinder head part device simple in structure.
The technical solution of the utility model is as follows: a kind of cylinder head part device, comprise cylinder, bracing frame (3) and installing plate (4), described cylinder is made of piston rod (2) and cylinder body (1), it is characterized in that: described piston rod (2) is regular polygon with nested one section its cross section that cooperates of cylinder body (1), the outer end of piston rod (2) is cylindrical, the end of this piston rod (2) outer end is fixedly connected with the middle part of installing plate (4), and piston rod (2) is perpendicular with installing plate (4), and the two ends of described installing plate (4) and bracing frame (3) fix.
Adopt above technical scheme, because used piston rod is regular polygon with the nested one section cross section that cooperates of cylinder block, so piston rod will be by circumferentially spacing, and can not relatively rotate between the cylinder body, also interior fixing will be rotated in the indirect fixing bracing frame of piston rod like this, thereby guaranteed that bracing frame in upper and lower motion head part, also can limit circumferential rotation, improved the smoothness of device head part.
Described piston rod (2) is square with nested one section the cross section that cooperates of cylinder body (1).The piston rod construction of square cross section is simple, and foursquare four right angles have good screens effect, effectively limited piston bar circumferential movement.
For simplified structure, make things convenient for processing and fabricating, described installing plate (4) is the rectangular flat structure.
Support frame as described above (3) is made of two the first square steel and two the second square steel, two the first square steel are parallel to each other, and separation is in the both sides of installing plate (4), end face at every the first square steel is evenly distributed with the cylindrical cushion block, connect by two the second square steel that are parallel to each other between two the first square steel, the middle part of two the second square steel bottom surfaces fits with the end of installing plate (4) end face respectively, and is bolted between the second square steel and the installing plate (4).Square steel structure framework has higher weight capacity and anti-deformation ability, can improve the Rigidity and strength of bracing frame.
The beneficial effects of the utility model are:
1) cylinder adopts not revolving structure, need not add guide pillar, guide pin bushing anti-rotation, makes the structure of whole head part device simpler, has reduced the error rate when pincers worker is installed, and has improved pincers worker efficient, thereby has improved mould production efficiency.
2) reduced the installing space of mould, the scope of application is wider.
3) effectively saved die cost.
