Description
Technical Field
The utility model relates to an automobile sleeve production facility, especially an automobile sleeve production is with thin rod material forging die that flattens.
Background
The patent with application number "201921213512.0" a four-column hydraulic press with a flat forging function "is a patent filed 2019 by the same company. The background section of this patent mentions: in order to realize the lowest-cost product forming process in the production process of automobile sleeve (automobile maintenance tool, used for disassembling nuts and the like) products produced by the company, the head of a metal bar needs to be upset (part of specifications needs to be upset twice), and then an inner hole is reversely extruded, so that the shape shown in fig. 8 is formed. The existing production equipment of the company only has one 800T four-column hydraulic press, and the press only has a vertical forging function, so that the production process of products with twice upsetting and once reverse extruding inner holes cannot be realized. If a special horizontal forging machine is additionally purchased, the production requirements of the company are not met, and the cost is high. Therefore, through the improvement of the equipment with low cost, the common four-column hydraulic machine has a practical flat forging function and has common practical significance for related industries. This patent is through improving original hydraulic press, sets up the lower die that can press from both sides tight mound to the bar, goes up the die to die one side sets up cylindric terrace die and the square head terrace die to bar extrusion under, utilizes the propelling movement of second pneumatic cylinder can accomplish mound, backward extrusion hole, and is simple, convenient, guarantees that the product accords with the production technology requirement.
The diameter of the bar stock adopted by the device is 30mm, and the corresponding holes on the lower concave die and the upper concave die are also corresponding to the bar stock. The length of the deformation involved in forging is no more than 3 times the diameter of the bar, as per the forging specification requirements. Therefore, the method can be directly finished by adopting thick bar stock through twice upsetting. But in the later period, the non-upsetting part of the bar stock needs to be processed into a semi-finished product with the diameter of 24mm on a machine tool, so that the material is greatly wasted, and the working efficiency is low. However, if a thinner bar such as 26mm is used, the length of deformation involved in forging exceeds 3 times the diameter of the bar and is not in accordance with the forging specification because of the tendency to destabilize deformation during too long upsetting.

And the lower die and the upper die are provided with standby holes which are the same as the first clamping holes.
The side die is provided with a mounting hole, and the male die is detachably fixed in the mounting hole.
The male dies comprise a cylindrical male die and a square-head male die, wherein the outer diameter of the cylindrical male die is consistent with the inner diameter of the rear positioning hole; the square-head male die and the automobile sleeve need to be punched in the same size.
The utility model relates to an automobile sleeve production is with thin bar material plain forging mould has following technological effect:
1) through with original lower mould, the aperture of the first clamping hole that the lower mould made up, second clamping hole changes 26mm into by 30mm to moving backward the mound portion in first clamping hole, can accomplish the mound of thin bar like this, solve and forge the problem that can't carry out thin bar long distance mound.
2) The upsetting of the thick bar can be completed by twice, the upsetting of the thin bar can be completed by once, and the front positioning hole and the rear positioning hole are arranged in front of and behind the first upsetting hole, so that the fixed positioning can be completed, and the deformation of the thin bar is avoided; in addition, the thin rod material can also reduce the later processing time and save materials.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the middle side mold of the present invention.
Fig. 3 is a top view of the middle and lower molds of the present invention.
In the figure: the die comprises a lower die 1, a lower die base 2, an upper die 3, a first clamping hole 4, a second clamping hole 5, a front positioning hole 4-1, a first pier coarse hole 4-2, a rear positioning hole 4-3, a fixing hole 5-1, a second pier coarse hole 5-2, a side die 6, a male die 7, a spare hole 8 and a mounting hole 9.
Detailed Description
As shown in figures 1-3, the fine bar material flat forging die for the production of the automobile sleeve comprises a lower die 1, wherein the lower die 1 is arranged on a lower die base 2, and an upper die 3 is arranged at the upper end of the lower die 1 in a right-to-right mode. The lower die 1 and the upper die 3 form a first clamping hole 4 and a second clamping hole 5 after being closed.
The first clamping hole 4 comprises a front positioning hole 4-1, a first upsetting hole 4-2 and a rear positioning hole 4-3, wherein the diameters of the front positioning hole 4-1 and the rear positioning hole 4-3 are the same and are both 26 mm. While the first upsetting hole 4-2 is consistent with the required upsetting portion of the bar.
The second clamping hole 5 comprises a fixing hole 5-1 and a second heading hole 5-2. Wherein the diameter of the fixing hole 5-1 is 26mm, and the second heading hole 5-2 is consistent with the first heading hole 4-2.
The lower die 1 and the upper die 3 are provided with spare holes 8 similar to the first chucking holes 4. After the first clamping hole 4 is roughened for a long time and deformed and worn, the spare hole 8 can be used for replacing and continuing to use, and the service life of the lower die 1 and the upper die 3 is prolonged.
One side of the lower die 1 is opposite to a side die 6, three mounting holes 9 are formed in the side die 6, and the mounting holes 9 correspond to the first clamping holes 4, the second clamping holes 5 and the standby holes 8 one to one. The two punches 7 are mounted in the corresponding mounting holes 9.
The male die 7 comprises a cylindrical male die 7-1 and a square-head male die 7-2, wherein the outer diameter of the cylindrical male die 7-1 is consistent with the inner diameter of the rear positioning hole 4-3, and the cylindrical male die 7-1 is opposite to the first clamping hole 4; when the first clamping hole 4 is worn, the cylindrical male die 7-1 is arranged at a position opposite to the spare hole 8. The square-head male die 7-2 is opposite to the second clamping hole 5, and the size of the square-head male die 7-2 required to be punched is consistent with that of the automobile sleeve.
The working principle and the process are as follows: a bar of 26mm diameter is placed in the first clamping hole 4. The upper die 3 moves downwards under the action of the first hydraulic oil cylinder and presses the bar stock tightly. The side die 6 is pushed towards the lower die 1 under the action of a second hydraulic oil cylinder, the cylindrical male die 7-1 enters the first clamping hole 4 and continuously extrudes the bar stock, and the redundant part of the bar stock is continuously extruded and enters the first upsetting hole 4-2. Because the first upsetting hole 4-2 is arranged between the front positioning hole 4-1 and the rear positioning hole 4-3, the diameters of the front part and the rear part of the bar are always kept unchanged until the front part of the bar completely enters the first upsetting hole 4-2 for forming.
And (3) placing the bar stock after upsetting into a second clamping hole 5, placing the upsetting part into a second upsetting hole 5-2, moving the side die 6 forwards again, and punching the upsetting part of the bar stock through the square-head male die 7-2.
