Description

Spinning machine

The utility model relates to a kind of pressure forming processing unit (plant).

The existing device of making the hollw article of pot body class generally adopts hydraulic drawing press.Adopt the hollw article of hydraulic drawing press manufacturing pot body class to have following shortcoming: 1, the vessel appearance is subjected to the restriction of processing conditions, can only process the identical vessel of wall thickness dimension, the vessel moulding of being made is single, stiff, can not satisfy the requirement that one-shot forming processing has the distinctive appearance vessel of different wall size; 2, spillage of material is big, must compress the limit of blank during owing to stretching, and behind the drawing and forming, the limit of blank abandons with regard to cut, so with regard to consume material; 3, die cost is big, produce the product of different size and must make corresponding punch, die earlier, and the manufacturing cost of punch, die is than higher.

In order to overcome the above-mentioned shortcoming of hydraulic drawing press, people have invented a kind of rotation-formed technology again, and this technology is to affect the blank that is clamped by the tail top by the core that is rotating, and the sheet material that will rotate by roller is pressed into required shape then.Adopt this technology to solve the above-mentioned defective of hydraulic drawing press theoretically.But how this technology is realized effectively that people are also among constantly groping.

Goal of the invention of the present utility model is to provide a kind of simple in structure, reliable, spinning machine that production efficiency is high.

The utility model is to realize like this, comprise frame, power drive mechanism, core, the tail top, tail top clamp mechanism, roller, the roller feed arrangement, power drive mechanism, tail top clamp mechanism relatively is fixed on the frame, the roller feed arrangement is fixed on the frame of power drive mechanism and clamp mechanism side, tail top, core is fixed on the main shaft of power drive mechanism, the tail top is fixed on the clamp mechanism of tail top, roller is fixed on the roller feed arrangement, its special feature is that the roller feed arrangement is mainly by rolling wheel support, radially-directed guide rail and planker, axially directed guide rail and planker, power transmission oil cylinder radially, axial power transmission oil cylinder, controlling organization constitutes, rolling wheel support is movably connected in the radially-directed guide rail, on the planker and by radially power transmission oil cylinder drive, the radially-directed guide rail, planker is movably connected in axially directed guide rail, drive on the planker and by axial power transmission oil cylinder, controlling organization is controlled radially, axial power transmission cylinder action.

During work, controlling organization by pre-set programs control radially, axially the power transmission oil cylinder is done feed motion, drive rolling wheel support and make moving of two-dimensional directional, drive the blank that roller relies on rotation, at this moment, under the control of controlling organization, roller is spun into required shape by the track that pre-set programs sets with blank.The employing oil cylinder drives, and has both guaranteed that roller can accurately move in short distance, can export enough pressure again simultaneously.

Here, controlling organization can be the microcomputer controlling organization, also can be the mechanical type controlling organization.When adopting the mechanical type controlling organization, controlling organization mainly is made of profile mould rack device, hydraulic follow-up valve, template, the hydraulic follow-up valve is fixed on the rolling wheel support, template is arranged on the profile mould rack device, the valve rod of hydraulic follow-up valve leans against on the template, the hydraulic oil input of hydraulic follow-up valve links to each other with the output of Hydraulic Station hydraulic oil, the hydraulic oil output of hydraulic follow-up valve respectively with accordingly radially power transmission oil cylinder hydraulic oil input link to each other.During work, drive rail radially, planker drive rail at the uniform velocity vertically under the drive of axial power transmission oil cylinder, move on the planker, the hydraulic follow-up valve moves and moves along with rolling wheel support, the valve rod of hydraulic follow-up valve leans against on the template, when the track of the track of rolling wheel support motion and the stem movement on the hydraulic follow-up valve is inconsistent, valve rod can be regulated the hydraulic pressure servo valve automatically, supply with the radially oil mass and the direction of power transmission oil cylinder by the adjustment of hydraulic follow-up valve, make the running orbit of roller consistent along the running orbit of template operation with the valve rod on the hydraulic follow-up valve, like this, just can control the running orbit of roller, make the profile of the outside, hollow products cross section that is processed identical with the profile of template, the shape of its endoporus is identical with the shape of core.

Operate for convenience, enhance productivity, be provided with a material-supporting device on the frame below the core termination.During work, earlier blank is placed on the material-supporting device, start spinning machine then, spinning machine starts material-supporting device by pre-set programs makes the sheet material blank move to predeterminated position, then the tail top clamps and automatically blank is fixed between core and tail top, the roller feed arrangement starts then, by roller blank is processed into required product.After having adopted material-supporting device, both improved the automaticity of producing, improved production efficiency again, also alleviated the labour intensity of operation simultaneously, when preventing that the operator from placing blank, crushed, strengthened the security of operation by core, tail top.

The utility model compared with the prior art, because adopted radially, axially directed guide rail and planker, rolling wheel support and corresponding power transmission oil cylinder and controlling organization, thereby have the advantage of the hollow products of realizing that accurately, efficiently, reliably shear spinning processing appearance and modeling is abundant.
