Abstract
A seamless tube forming device comprises a squeezing barrel, a hollow squeezing rod, a needle support and a mold. The hollow squeezing rod is sleeved in the squeezing barrel, the needle support is sleeved in the hollow squeezing rod, the mold is installed on the squeezing barrel, and the mold is coaxially arranged with the needle support. The seamless tube forming device is characterized in that the matching surface of the squeezing barrel and the mold is in conical surface slope matching, and a guide copper sleeve is sleeved on the hollow squeezing rod. By designing the matching surface of the squeezing barrel and the mold into conical surface slope matching, the seamless tube forming device effectively improves centering performance and stability of the mold. Simultaneously, by assembling the guide copper sleeved on the hollow squeezing rod, the seamless tube forming device can improve the centering accuracy and strength of the needle support corresponding to the mold and effectively solves the problem of eccentricity. The eccentricity degree of a seamless aluminum tube is improved to 5%-7% from original 15%, and passing rate of products is remarkably improved.
Description
Technical field
The utility model relates to technical field of mold, specifically a kind of seamless pipe shaped device that is used for preparing seamless Al-alloy pipe.
Background technology
Utilizing aluminium bar to produce in the process of seamless aluminium tubing, because the design of existing forming die structure is unreasonable, having the eccentric problem of aluminum pipe, the eccentric request of national standard that surpasses will be scrapped, and cause loss.
The utility model content
The purpose of the utility model is to provide a kind of seamless pipe shaped device, improves the qualification rate of seamless aluminium tubing product.
The technical scheme that its technical problem of the utility model solution is taked is: this kind seamless pipe shaped device, comprise that recipient, hollow pressure ram, pin support and mould, and said hollow pressure ram is nested with in recipient; Said pin supports and is nested with in hollow pressure ram; Said mould is installed on the recipient, and said mould supports coaxial setting with pin, it is characterized in that; Said recipient cooperates for conical surface gradient with the mating surface of mould, is nested with a guiding copper sheathing on the said hollow pressure ram.
The beneficial effect of the utility model is: the utility model becomes conical surface gradient to cooperate through the registration interface designs with mould and recipient, effectively improved mould to neutral and stable; Assembling guiding copper sheathing on hollow pressure ram can improve pin and support accuracy of alignment and intensity with respect to mould simultaneously, efficiently solves eccentric problem.Make the degree of eccentricity of seamless aluminium tubing bring up to 5% to 7% by original about 15%, the qualification rate of product increases considerably.
Description of drawings
Fig. 1 is the full sectional view of the utility model;
Among the figure: 1 recipient, 2 hollow pressure rams, the support of 3 pins, 4 moulds, 5 guiding copper sheathings.
The specific embodiment
It is as shown in Figure 1,
The seamless pipe shaped device comprises recipient 1, hollow pressure ram 2, pin support 3 and mould 4.
Recipient 1 is the parts of a tubular, and a hollow pressure ram 2 is nested with in recipient, and the other end of recipient 1 is installed a mould 4, and mould is columned.Recipient cooperates for conical surface gradient with the mating surface of mould, and uses bolted, so just can guarantee installation accuracy.Hollow pressure ram 2 is the parts of a tubular; Can in recipient 1, slide front and back; A pin supports 3 and is nested with in hollow pressure ram, and pin support 3 also can be slided front and back in hollow pressure ram, precision and stability when supporting slip for the assurance pin; On hollow pressure ram, be nested with a guiding copper sheathing 5, the guiding copper sheathing is that the pin support provides a strong point.
In the process of installing, should guarantee pin support, hollow pressure ram and the coaxial setting of mould.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
