Abstract

The utility model relates to a part structure of a processing device for automobile parts, in particular to a multi-station pipe end forming device for a manifold applied to the exhaust manifold processing of automobile engines. The device comprises an upper mould and a lower mould which can be fastened with each other. After the upper mould and the lower mould are fastened with each other, an inner cavity which is matched with the shape of a manifold to be processed and can clamp and fix the manifold is formed. Four hydraulic cylinder supports are fixedly arranged on a base body of the lower mould, and each hydraulic cylinder support is provided with a hydraulic cylinder. Extensible parts of four hydraulic cylinders respectively drive a circle pipe end sizing mould head, a circle pipe end cutting mould head, a special-shaped pipe end forming mould head and a special-shaped pipe end cutting mould head. The multi-station pipe end forming device for the manifold has wide application, is convenient to install and use, enables the pipe end of the whole manifold to be once formed in a process, avoids position errors caused by multi-positioning, improves processing accuracy of products, and reduces scrappage.

Description

Multistation manifold forming apparatus for forming pipe end

Technical field

The utility model relates to a kind of equipment part structure of auto parts, specifically is a kind of multistation manifold forming apparatus for forming pipe end that is used for the processing of automobile engine to exhaust manifold.

Background technology

The automobile engine to exhaust manifold is the complicated special-shaped tubular part of a kind of shape, and its main body is a warp architecture, and in two pipe ends, an end is common circular pipe end, and the other end is the special-shaped pipe end of polymorphic structure.Because it is complex-shaped, need just can finish the moulding and the cutting of the two ends mouth of pipe in traditional process by multiple working procedure, the process complexity, repeatedly the location fiducial error is caused in the location, and making has increased manufacturing cost by product processed percent defective height.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of processing technology that can simplify the engine exhaust manifold is provided, improves the accuracy of manufacture, improves yield rate, reduces the multistation manifold forming apparatus for forming pipe end of manufacturing cost.

Multistation manifold forming apparatus for forming pipe end of the present utility model include a pair of can involutory mutually upper die and lower die, the involutory back of upper and lower mould forms one and adapts, also can grip the inner chamber of manifold with manifold shapes to be processed; Be installed with four hydraulic cylinder legs on the matrix of counterdie, a hydraulic cylinder is installed on each hydraulic cylinder leg, and the telescopic section of four hydraulic cylinders drives a circular pipe end plug die head respectively, a round tube end-grain cutting is cut die head, a special-shaped pipe end molding die and a special pipe end-grain cutting and cut die head; The flexible direction of described circular pipe end plug die head can be carried out the sizing moulding to the circular pipe end of manifold to be processed over against the circular pipe end of manifold to be processed; The flexible direction that die head is cut in described round tube end-grain cutting parallels with the end face of the circular pipe end of manifold, can cut the end face that forms circular pipe end; The flexible direction of described special-shaped pipe end molding die can be carried out extrusion modling to the special-shaped pipe end of manifold to be processed over against the special-shaped pipe end of manifold to be processed; It is parallel with the end face of the special-shaped pipe end of manifold that the flexible direction of die head is cut in described special pipe end-grain cutting, can cut the end face that forms special-shaped pipe end.

The utility model can equally with common mould be installed on the pressure forming machine, can utilize four the hydraulic cylinder fuel feeding of the Hydraulic Station of equipment for the utility model device, wide adaptability, easy to install; Because the die head to the moulding and the cutting of two pipe ends has been installed on same clamping jig simultaneously, make the pipe end of whole manifold be molded in the operation and can once finish, avoided repeatedly locating the position error that causes, improved processing precision of products, reduced scrappage.

The specific embodiment

As shown in the figure, this device includes a pair of patrix 1 and counterdie 2 that can be involutory mutually, and the involutory back of upper and lower mould forms one and adapts, also can grip the inner chamber 4 of manifold with manifold 3 shapes to be processed; Be installed with four hydraulic cylinder legs 5 on the matrix of counterdie, the telescopic section that 6, four hydraulic cylinders of a hydraulic cylinder are installed on each hydraulic cylinder leg drives a circular pipe end plug die head 7, round tube end-grain cutting respectively and cuts die head 8, a special-shaped pipe end molding die 9 and a special pipe end-grain cutting and cut die head 10; The flexible direction of circular pipe end plug die head 7 can be carried out the sizing moulding to the circular pipe end of manifold to be processed over against the circular pipe end of manifold to be processed; The flexible direction that die head 8 is cut in the round tube end-grain cutting parallels with the end face of the circular pipe end of manifold, can cut the end face that forms circular pipe end; The flexible direction of abnormity pipe end molding die 9 can be carried out extrusion modling to the special-shaped pipe end of manifold to be processed over against the special-shaped pipe end of manifold to be processed; It is parallel with the end face of the special-shaped pipe end of manifold that the flexible direction of die head 10 is cut in the special pipe end-grain cutting, can cut the end face that forms special-shaped pipe end.

Each hydraulic cylinder alternating movement in this device busy process, earlier carry out moulding, cut die head 8 and special pipe end-grain cutting by the round tube end-grain cutting again and cut die head 10 the redundance cutting of pipe end is removed by circular pipe end plug die head 7 and 9 pairs of two pipe ends of special-shaped pipe end molding die.
