Abstract
The utility model discloses a double-ejection structure of a part forming machine, which comprises a base. A vertical left punched hole and a vertical right punched hole are arranged on the base, and a left ejector rod and a right ejector rod are arranged in the left punched hole and the right punched hole respectively. The double-ejection structure is characterized in that a horizontal ejector plate is movably arranged below the left ejector rod and the right ejector rod, the ends of the left ejector rod and the right ejector rod are connected with the upper surface of the ejector plate, and the ejector plate is connected with the base through a plurality of elastic elements. The double-ejection structure has the advantages that synchronism of the two ejector rods is better, and the defective rate of products is lower.
Description
Technical field
The utility model relates to a kind of parts shaping machine, relates in particular to a kind of Double Tops material structure of parts shaping machine.
Background technology
Present stage, the stamped metal product need be with original workpiece drawing in its production process; This process mainly relies on punching and drift to cooperate and accomplishes, and during punching press, a movable push rod is arranged in the punching; This push rod can move up and down, and this push rod contacts with the workpiece that is positioned at punching, after workpiece is stamped moulding; The workpiece that push rod moves upward and is in contact with it with jack-up, workpiece ejects punching the most at last, and the workpiece that is ejected punching is clamped to the material stock zone by chuck again; When workpiece is retained in the process in material stock district, push rod moves downward to starting point.The metal current compacted products adopts the parts shaping machine with Double Tops material structure usually in its production process; This Double Tops material structure production efficiency is higher; But it requires the synchronism of two push rod motions in the Double Tops material structure better in actual use; Thereby the defect rate that guarantees product is lower, generally is provided with left push rod and right push rod in the Double Tops material structure of existing parts shaping machine, and moving up and down of this left side push rod and right push rod is to rely on the top board of power set jack-up to realize; The qualification rate higher requirement that satisfies the stamped metal product is that an end of top board is when making progress jack-up left side push rod to peak; Right push rod then moves downward to minimum point, but since top board of the prior art be connected with the support of make-up machine is non-resilient, to such an extent as to left push rod when perhaps right push rod does not often move to minimum point just owing to stopping of top board stops; Therefore two push rod synchronisms are relatively poor, to such an extent as to the defect rate of product is higher.
Summary of the invention
It is better that the utility model technical problem to be solved provides a kind of push rod synchronism, the Double Tops material structure of the parts shaping machine that the defect rate of product is lower.
For solving the problems of the technologies described above; The utility model provides a kind of Double Tops material structure of parts shaping machine, comprises support, has vertical left punching and right punching on the said support; Be respectively arranged with left push rod and right push rod in said left punching and the said right punching; The underside of said left push rod and said right push rod be provided with a horizontal top, the upper surface joint of the end of said left push rod and said right push rod and said top board, said top board is connected with said support through a plurality of flexible members.
Said flexible member is a helical spring.
The quantity of said flexible member is four, and evenly is provided with at interval.
Compared with prior art, the beneficial effect of the utility model is:
Because the top board of the Double Tops material structure of a kind of parts shaping machine of the utility model is connected with support through a plurality of flexible members; Thereby make left push rod or right push rod when moving downward, can continue to compress top board downwards to minimum point; Finally make left push rod or right push rod move to minimum point; Thereby when having guaranteed that in left push rod or the right push rod one moves to peak; In left side push rod or the right push rod another can move to minimum point, so the utility model push rod synchronism is better, and the defect rate of product is lower.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: support 10, left punching 12, right punching 14, left push rod 16, right push rod 18, top board 19, helical spring 20.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details
Referring to shown in Figure 1; A kind of Double Tops material structure of parts shaping machine; Comprise support 10, vertically on this support 10 offer the ccontaining left punching 12 and right punching 14 of treating the pressed metal part, movable respectively left push rod 16 and the right push rod 18 of being provided with in left punching 12 and right punching 14; This left side push rod 16 can move up and down in left punching 12 and right punching 14 with right push rod 18; The underside of left side push rod 16 and right push rod 18 is provided with a horizontal top 19, the end of left push rod 16 and 18 right push rods and top board 19 joints, and this top board 19 is connected with support 10 through four helical springs 20 that are provided with at interval; Thereby through helical spring 20 top board 19 is connected with support 10 and makes left push rod 16 or right push rod 18 when moving downward, can continue to compress top board 19 downwards to minimum point; Finally make left push rod 16 or right push rod 18 move to minimum point, thereby when having guaranteed that in left push rod 16 or the right push rod 18 one moves to peak, another can move to minimum point; Thereby the synchronism that guarantees push rod is better, and the qualification rate of product is higher.
Therefore the synchronism of two push rods of the utility model is better, and the defect rate of product is lower.
The above is merely the preferred embodiments of the utility model; The protection domain of the utility model does not exceed with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
