Description

Die holder

Affiliated technical field

The utility model relates to and is used to adjust stamping parts in a kind of mechanical manufacturing field, particularly the inhomogeneity die holder of hub axle tube wall thickness difference.

Background technology

In the manufacturing process of hub axle tube, die holder is the important component part of fixed mould, and the reasonability of its structural design is for the production important influence of product.Hub axle tube is the product of producing under the hot extrusion state, the quality of its quality not only depend on burning, overheated, fillet is excessive, subside and the defective of interior outward appearance, the more important thing is the total quality important influence of the uniformity of wall thickness difference to blank.Blank is subjected to the influence of numerous factors such as the reasonability of equipment, temperature, frock and adjustment under the hot extrusion state, and adjusting centering is to make the uniformity of blank wall thickness difference reach one of quick method of standard-required.This just requires appropriate design die holder mechanism, and is poor to reach accurate, practical effect and can control wall thickness effectively, to satisfy the processing quality requirement of product.In the traditional mode of production process, when wall thickness difference during, to adjust frock just must be connected die holder with workbench fastening T type bolt and all unclamp greater than the scope of technological requirement, whole mobile die holder just can reach mould centering.Not only want breaks in production, and waste time and energy, also might cause the generation of waste product in the follow-up adjustment.

Summary of the invention

For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of die holder, adjust bolt and water service pipe by increasing in the die holder side, between mould and die sleeve, increase the profit water system, to reach convenient, fast adjustment centering, make the uniformity of blank wall thickness difference reach standard-required, and make the effective cooling purpose of mould.

The technical solution of the utility model is: workbench and die holder are connected as a single entity by connector, along die holder axial centre symmetry stepped bore is arranged, die-cushion is equipped with at the lower boss place in hole, the upper surface of die-cushion is equipped with die-cushion, its axial centre symmetry all has through hole, on die-cushion, be provided with mould, be with water jacket and die sleeve between mould, die-cushion and the die holder, die sleeve is at the upper surface of die-cushion, gland and die holder are connected as a single entity by connector, it is characterized in that: the die holder footpath is porose towards periphery, and the adjusting bolt is housed in the hole.

Hole towards periphery, die holder of the present utility model footpath is a stairstepping, in the hole, the circumference of regulating bolt is with and inserts, and studs with non-slipping block at the circumference of inserting, shoulder hole boss place.

Be with water jacket between mould of the present utility model and the die sleeve, along water jacket axial centre symmetry through hole is arranged, annular water tank is arranged on the hole wall, the top of water jacket is radially porose, die holder, die sleeve radially porose respectively, water service pipe is equipped with in its hole in the hole on same axis, gapped between water jacket and the die sleeve, communicate with water service pipe, the radially bottom of die sleeve (11) is porose, and a cooling system is formed with the radial hole on die sleeve bottom, water jacket top in the gap between water service pipe, annular water tank, water jacket and the die sleeve.

The utility model is adjusted bolt by increasing in the die holder side, only need use the spanner that matches adjustment bolt fastening or loosening symmetry just can reach the purpose of mould centering when adjusting centering; Simultaneously, cooling water is by water service pipe, through the outer wall of the even cooling die of annular water tank of die sleeve and water jacket, and cooperatively interacts inside and outside the cooling water of cooling endoporus, can effectively improve the service life of mould.

The utility model compared with prior art has the following advantages:

1, can convenient and swift adjustment wall thickness poor, alleviate operative employee's labour intensity;

Needn't stop the continuation heating of raw material when 2, adjusting, avoid post bake, guarantee ongoing operation, can effectively enhance productivity;

3, can effectively avoid burning, superheating phenomenon, reduce the waste product that the secondary debugging produces, in time adjust centering, reduce overproof product, the percent defective of control product;

4, can avoid the heating for multiple times of shaping blank not and the secondary of supplementary energy to take place, energy savings, reduce and consume.

Accompanying drawing is a structure diagram of the present utility model.

The specific embodiment

As shown in drawings, on the die holder 2, the bottom is a flange arrangement, there is through hole at workbench 1 center, workbench 1 is connected as a single entity by screw with the bottom of die holder 2, along die holder 2 axial centre symmetries stepped bore is arranged, die-cushion 3 is equipped with at the lower boss place in hole, to be used at punching course protection die holder 2, the upper surface of die-cushion 3 is equipped with die-cushion 4, its height, in, the variety classes of external diameter and mould 8 matches, die-cushion 3, the axial centre symmetry of die-cushion 4 all has through hole, is provided with mould 8 on die-cushion 4, by gland 12 it is pushed down mould 8, be with water jacket 10 successively between mould 8 and the die holder 2, die sleeve 11, between water jacket 10 and the die sleeve 11, all gapped between die sleeve 11 and the die holder, water jacket 10, all at the upper surface of die-cushion 3, gland 12 is connected as a single entity by screw with the upper surface of die holder 2 die sleeve 11; Die holder 2 footpaths have four stepped bore towards periphery, be equipped with in the hole and regulate bolt 6, be used for when the blank evenness of wall thickness is overproof, adjusting centering, only need use the spanner that matches adjustment bolt 6 fastening or loosening symmetry just can reach the purpose of mould centering when adjusting centering, in the hole, the circumference of regulating bolt 6 is with and inserts 7, inserting 7 has tapped through hole, studs with non-slipping block 5 at insert 7 circumference, shoulder hole boss place, is securely fixed in the hole so that regulate bolt 6.

In hot extrusion was produced, mould was subjected to high temperature and huge impact pressure for a long time, and turned blank produces strong friction to mould in thermal deformation process simultaneously, makes mould very easily cause fatigue, wearing and tearing, even cracking causes mould to scrap.In the very high continuous production of frequency, effectively cooling is particularly important in many measures, waters water cooling improperly the inhomogeneous initial failure that causes of mold temperature is scrapped.Be with water jacket 10 between mould 8 of the present utility model and the die sleeve 11, along water jacket 10 axial centre symmetries through hole is arranged, annular water tank is arranged on the hole wall, the top of water jacket 10 is radially porose, die holder 2, die sleeve 11 radially porose respectively, its hole is on same axis, water service pipe 9 is housed in the hole, gapped between water jacket 10 and the die sleeve 11, communicate with water service pipe 9, the radially bottom of die sleeve 11 is porose, and a cooling system is formed with the radial hole on die sleeve 11 bottoms, water jacket 10 tops in the gap between water service pipe 9, annular water tank, water jacket 10 and the die sleeve 11.Cooling water by the even cooling die of cooling system outer wall and the cooling water of cooling endoporus inside and outside cooperatively interact, it is even to reach the mould internal and external temperature, has reduced the thermal stress that monolateral local cooling causes and has concentrated the service life that can effectively improve mould.
