Abstract
The utility model relates to the field of blank processing equipment, and discloses a forged split type trimming lower die, which solves the problems that the conventional blank is easy to hold tightly with the trimming lower die and is not easy to separate from a die blank when being cooled; according to the utility model, the second lower die is connected with the first lower die through the matching of the bottom plate, the connecting bolt and the top plate, the two long lower dies are arranged, and the material returning mechanism is arranged in the middle of the top of the first lower die, so that a blank is prevented from being cooled and tightly clasped on the second lower die and is not easy to separate from the second lower die.
Description
Technical Field
The utility model belongs to the field of blank processing equipment, and particularly relates to a forged split type trimming lower die.
Background
The trimming die is a stamping die which is used for trimming the edge of a workpiece in a trimming process by utilizing a stamping die to enable the workpiece to have a certain height, diameter and shape, is mainly used for trimming the edge of a drawn workpiece, enables the end face to be flat and attractive, and is convenient for next-step assembly, and is widely applied to the fields of mechanical manufacturing, automobile part production, beverage bottle processing, fastener die matching and the like.
A whole set of traditional mould includes one set of mould and one set of lower mould, and every section wheel type corresponds one set of mould, and the subassembly is not public, needs whole the change during the remodelling, wastes time and energy, and the mould expense is also higher, and when the blank cools off, holds tightly with the side cut lower mould easily, and difficult mould base separation (see figure 1).
SUMMERY OF THE UTILITY MODEL
Aiming at the situation, in order to overcome the defects of the prior art, the utility model provides the forging split type trimming lower die, and effectively solves the problems that the blank is easy to hold with the trimming lower die and is difficult to separate from a die blank when being cooled at present.
In order to achieve the purpose, the utility model provides the following technical scheme: forge split type side cut lower mould, including first lower mould, the second lower mould is installed to the top of first lower mould, and the mould is installed to the top of second lower mould, goes up and installs the blank between mould and the second lower mould, and the top fixed mounting who goes up the mould has the mounting panel, and the top fixed mounting of first lower mould has the roof.
Preferably, a concave die is arranged at the top of the second lower die, and an independent component is arranged inside the concave die.
Preferably, a positioning pin is installed between the second lower die and the top plate.
Preferably, a bottom plate is installed at the bottom of the second lower die, and a connecting bolt is installed between the bottom plate and the top plate.
Preferably, a material returning mechanism is installed in the middle of the top of the first lower die.
Compared with the prior art, the utility model has the beneficial effects that:
(1) according to the utility model, the second lower die is connected with the first lower die through the matching of the bottom plate, the connecting bolt and the top plate, two longer lower dies are arranged, and the material returning mechanism is arranged in the middle of the top of the first lower die, so that a blank is prevented from cooling and tightly holding the second lower die and being not easy to separate from the second lower die;
(2) this is novel to set up the die through the top at the second lower mould to with the inside independent subassembly that sets to of die, convenient change, when the wheel type switches, labour saving and time saving, the cost of manufacture is low.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the first embodiment, as shown in fig. 1 to 3, the die comprises a first lower die 1, a second lower die 8 is mounted above the first lower die 1, an upper die 6 is mounted above the second lower die 8, a blank 5 is mounted between the upper die 6 and the second lower die 8, a mounting plate 7 is fixedly mounted at the top of the upper die 6, a top plate 3 is fixedly mounted at the top of the first lower die 1, a material returning mechanism 9 is mounted in the middle of the top of the first lower die 1, a bottom plate 4 is mounted at the bottom of the second lower die 8, a connecting bolt 2 is mounted between the bottom plate 4 and the top plate 3, the first lower die 1 and the second lower die 8 are arranged, and the material returning mechanism 9 is arranged, so that the blank 5 is prevented from being tightly held with the trimming lower dies, and the die blanks are not easy to separate.
In the second embodiment, on the basis of the first embodiment, a concave die 10 is arranged at the top of the second lower die 8, and the inside of the concave die 10 is arranged into an independent component;
the trimming lower die is designed to be shared, the die 10 is designed to be an independent component, replacement is convenient, time and labor are saved when the wheel type is switched, and the manufacturing cost is low.
In the third embodiment, on the basis of the first embodiment, a positioning pin 11 is installed between the second lower die 8 and the top plate 3;
and a female die is added for positioning, so that the positioning is more accurate, and the matching error of the blank 5 and the die is about 0.3 mm.
