Before the device is used for stamping, an upper die frame 1 and a lower die frame 2 of a main die frame are required to be installed on a press through hoisting holes, die frame positioning grooves arranged on the front side and the rear side of the upper die frame 1 and the rear side of the lower die frame 2 are fixedly connected with the press through a thread external connection fixing device, and therefore the upper die frame 1 and the lower die frame 2 can complete fully matched stamping actions under the control of the press.
After the main die frame is installed, an upsetting die, a finish forging die and a trimming and punching die are required to be installed in sequence:
when installing the upsetting forging, the two upsetting die holders 31 need to be respectively positioned and installed on the upper die carrier 1 and the lower die carrier 2 through the die guide grooves, and then the upsetting die upper die 33 and the upsetting die lower die 32 with corresponding specifications are selected according to the specification of the blank to be processed and respectively installed on the two upsetting die holders 31, wherein the specific installation steps of the upsetting die lower die 32 are as follows:
step 100, firstly, aligning wedge positioning grooves 321 at four corners of an upsetting die lower die 32 to positioning wedges 311 at four corners of a boss structure of an upsetting die holder 31, and in the process of attaching the upsetting die lower die 32 to the upsetting die holder 31, fully fitting and accurately butting the upsetting die lower die 32 and the upsetting die holder 31 under the action of the four wedge positioning grooves 321 and the four positioning wedges 311;
200, after the lower upsetting die 32 and the upsetting die holder 31 are fully attached, at the moment, the die plate countersunk holes 322 at the four corners of the lower upsetting die 32 coincide with the wedge table screw holes 312 at the four corners of the upsetting die holder 31, and the lower upsetting die 32 is fixed on the upsetting die holder 31 through the bolts screwed in the four corners by putting the bolts into the die plate countersunk holes 322 and screwing the bolts into the wedge table screw holes 312.
Step 300, after the upsetting die lower die 32 and the upsetting die holder 31 are fully attached and fixed, the bottom opening of the blank upsetting lower cavity 323 in the middle of the upsetting die lower die 32 is butted with the top opening of the die holder blank cavity 313 in the middle of the upsetting die holder 31, the spring 61 is firstly placed into the cavity screw 314 in the die holder blank cavity 313, and then the die holder cavity inner slide block 62 is placed into the die holder blank cavity 313, so that the spring 61 elastically lifts the die holder cavity inner slide block 62 to slide up and down along the die holder blank cavity 313 to support the placed blank.
When the upper upsetting die 33 is installed, the fixed connecting screw 333 needs to be screwed into the cavity screw 314 of the other upsetting die holder 31 in advance until the upper cavity inner slide 332 at the top end of the fixed connecting screw 333 presses the upsetting die holder 31, so that the pressure applied to the upper cavity inner slide 332 is applied to the upsetting die holder 31, and then according to the steps, the upper upsetting die 33 is installed on the upsetting die holder 31, and the upper cavity inner slide 332 is ensured to extend into the blank upsetting upper cavity 331 at the middle part of the upper upsetting die 33 in the installation process, so that the installation of the upper upsetting die 33 can be completed.
After the upper upsetting die 33 and the lower upsetting die 32 are mounted, the blank heated to a proper temperature is placed into the lower die holder blank cavity 323 at the middle part of the lower upsetting die 32, then the blank naturally falls into the upper die holder blank cavity 313 of the upper upsetting die holder 31 at the bottom end and is elastically supported by the slide block 62 in the die holder cavity, at this time, the press machine is started to control the upper die holder 1 to move towards the lower upsetting die 32 together with the upper upsetting die 33 until the upper part of the blank extends into the upper blank upsetting cavity 331 at the middle part of the upper upsetting die 33 until the top end of the blank is in contact with the upper cavity inner slide block 332 in the upper blank upsetting cavity 331, at this time, the blank is extruded by the upper cavity inner slide block 332 and the slide block 62 in the die holder cavity along with the continuous descending of the upper upsetting die 33, and the outline of the blank is limited by the lower blank upsetting cavity 323, the upper blank cavity 323 and the blank cavity 313 until the upper die holder 33 and the lower die 32 are completely closed, the shape of the blank is stamped to form a head upset blank that conforms to the local configuration of the lower blank upset cavity 323, the upper blank upset cavity 331, and the die holder blank cavity 313.
When the blank is positioned in the blank upsetting lower cavity 323, the blank upsetting upper cavity 331 and the die holder blank cavity 313 and is punched by the upper cavity inner slide block 332 and the die holder inner slide block 62, the die holder inner slide block 62 transmits the received pressure to the spring 61, and continuously moves downwards along the die holder blank cavity 313 under the compression action of the spring 61 until the die holder inner slide block 62 is supported by the cavity inner screw hole 314 and does not descend any more, so that after the blank is upset, the upper die holder 1 is controlled by the press to lift the upsetting die upper die 33 upwards to separate from the upsetting die lower die 32, the spring 61 releases the elastic force to lift the die holder inner slide block 62 upwards along the die holder blank cavity 313, and simultaneously, the head upsetting blank positioned in the blank upsetting lower cavity 323 and the die holder blank cavity 313 is lifted by a distance, so as to facilitate subsequent processing and material taking.
The upsetting die 3 is of a vertically assembled structure, positioning is provided by the installation of the lower upsetting die holder and the main die carrier, blanks are stamped by the assembled templates, when the specification of the upset blanks needs to be switched, only the assembled templates need to be replaced, and the upsetting die holder does not need to be detached from the main die carrier, so that the upsetting die can be quickly installed and detached while the stamping precision is guaranteed, and the production efficiency is improved;
the die holder blank cavity 313 and the cavity inner screw 314 which are butted with the die plate are arranged in the upsetting die holder 31, and the die holder cavity inner slide block 62 and the spring 61 are arranged in the inner cavity of the upsetting die holder 31 on the lower die holder 2 for automatically ejecting the upset blank so as to be convenient for taking out the head upset blank from the upsetting die subsequently,
in addition, the die holder fixing screw 333 and the upper cavity inner slide block 332 are installed in the cavity screw 314 of the upsetting die holder 31 on the upper die holder 1 to replace the upsetting die main body to punch blanks, and the service life of the whole device is prolonged by subsequently replacing the die holder upper cavity inner slide block 332 and the fixing screw 333.
The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
