Embodiment

[0047] Such as Figure 5 The cold extrusion stretching production process of the shown T-shaped sleeve comprises the following steps:

[0048] 1) Cut the material to form a blank;

[0049] 2) Preforming, forming preforms through cold heading;

[0050] 3) Stretching, stretching the preform to a specified size;

[0051] 4) Punching to form a finished product.

[0052] Specifically, the cold extrusion stretching production process of the above-mentioned T-shaped sleeve also includes the following steps:

[0053] 1) The cold heading machine first cuts the blank;

[0054] 2) The clamping table sends the blank into the mouth of the first die, and the first punch sends the blank into the main mold of the first die for pre-heading;

[0055] 3) After the pre-upsetting is completed, the clamping table sends the pre-upsetting material of the first die into the second die opening, and then the second punch performs the initial upsetting to shape the shape of the head, the diameter of...

Abstract

The invention discloses a cold extruding and drawing production technology of a T-type sleeve, and belongs to the technical field of molds. The cold extruding and drawing production technology comprises the following steps that (1) a cold header cuts a blank first; (2) the blank is sent into an opening of a mold I by a clamping platform, and the blank is sent into a master mold of the mold I by astamping mold I to be pre-upset; (3) after pre-upsetting is finished, the clamping platform sends a mold I pre-upset material into an opening of a mold II, then a stamping mold II performs initial upsetting, the shape and bore diameter of a head part and a tail part chamfering are molded; (4) after initial upsetting is finished, the clamping platform sends a mold II initial upsetting material intoan opening of a mold III, a stamping mold III performs final upsetting, the diameter and the bore diameter of the head part are subjected to upsetting into required sizes, and a tail part is punched;(5) after final upsetting is finished, the clamping platform sends a mold III final upsetting material into an opening of a mold IV, and the tail part bore diameter is drawn; (6) after drawing is finished, the clamping platform sends a mold IV drawing material into an opening of a mold V, and a hole which is closed after drawing is pierced; and (7) after piercing is finished, the clamping platformsends a mold V piercing material into an opening of a mold VI, the a cylinder waste material of the head part is cut off, and molding is finished.

Description

technical field [0001] The invention belongs to the field of advanced production and manufacturing technology, and in particular relates to a cold extrusion and stretching production process of a T-shaped sleeve. Background technique [0002] At present, the cold extrusion and stretching production process of T-shaped sleeves: ①Procedure: first blank the plate, ②process: punch the plate into the diameter of the required size, ③process: punch the plate into the required size, ④Procedure: Bend the blanked sheet, ⑤Process: Side bend, ⑥Process: Bending and shaping, ⑦Process: Hemming. [0003] The iron plate is punched out to the shape and size required by the product by the punching machine, and the plate is punched, bent, and shaped to meet the required shape and size requirements (such as figure 1 , 2 shown). [0004] Due to the process, the plate is formed into a cylindrical shape after hemming, and after the plate is punched, burrs are often generated, and subsequent pers...
