[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts. Various stamping dies are also needed in the processing of automobile chassis.

[0003] Publication No. CN205763197U discloses a stamping die for automobile chassis, which can fix multiple processed parts by installing multiple sets of lower die seats on the working platform, and can drive the working platform to rotate through a rotating table, so that the working platform drives the lower die seat to rotate, and the upper film seat can be driven by a hydraulic device to process parts, so that large-scale production can be achieved. However, during the production process, the mold will be damaged after long-term use, reducing the service life of the mold, and when there is large friction, regular lubrication and maintenance are required to ensure the normal use of the mold to reduce the wear caused by friction and affect the stamping effect. To this end, we propose a stamping die for automobile chassis. Utility Model Content

[0025] An extrusion spray component 10 is slidably installed on the top of the mold frame 1 through an elastic reset structure. A spray port 11 is opened through the top of the inner side wall of the extrusion spray component 10. A buffer pad 9 for buffering is provided on the top of the extrusion spray component 10. A stamping component 12 is arranged above the mold frame 1. The top of the stamping component 12 is fixedly installed on the bottom end of the extension rod 13. The two sides of the extension rod 13 are respectively fixedly connected to the limiting rod 14, and the limiting rod 14 is slidably connected to the outer periphery of the limiting rod 14 in the auxiliary support frame 15.

[0026] When in use, multiple buffer structures are used to reduce the damage to the die frame 1 when the stamping part 12 impacts the die frame 1 during stamping, so that the entire die frame 1 can buffer the impact force, and the stamped automobile chassis can be quickly and conveniently removed from the stamping equipment, and the service life of the bottom die is extended. The structure that sprays lubricating oil during the buffering process reduces the wear caused by contact between structures, further improving the service life of the equipment.

[0027] As shown in the figure, the extension rod 13 pushes the punching part 12 through the hydraulic punch 16 to punch the plate.

[0028] When in use, the hydraulic punch 16 operates to push the punching piece 12 at the bottom of the extension rod 13 to punch the sheet material.

[0029] As shown in the figure, the outer wall of the extrusion spraying member 10 is connected with an oil delivery pipe.

[0030] When in use, lubricating oil is delivered to the extrusion spray member 10 through the oil delivery pipe.

[0031] As shown in the figure, buffer pillars 8 for buffering and unloading force are installed at the four corners of the bottom end of the mold frame 1.

[0032] When in use, the mold frame 1 is supported by the buffer pillar 8 to move downward to complete the buffering, and the collecting table 2 is assisted to place the stamped automobile chassis to prevent it from moving on the collecting table 2 and falling.

[0033] As shown in the figure, a material unloading platform 4 for unloading materials is arranged on the side of the collecting platform 2 away from the electric push rod 6 .

[0034] When in use, the chassis pushed out of the collecting station 2 is collected by the unloading station 4 .

[0035] The working principle and use process of the utility model are as follows: a sheet is placed on the top surface of the extrusion spraying part 10, and then the hydraulic punch 16 is operated to push the stamping part 12 installed at the bottom end of the extension rod 13 to move downward, thereby extruding the sheet into shape. During the stamping process, the stamping part 12 abuts against and pushes the extrusion spraying part 10 and the mold frame 1 to move downward. The stamping part 12 is vertically displaced under the restriction of the limiting slide column in the limiting rod 14 in the auxiliary support frame 15. The mold frame 1 abuts against the collecting table 2 under the buffering of the buffer support 8 at the bottom end. The collecting table 2 is supported and fixed in position by the support base 3 to cooperate with the stamping. Forming, the sheet starts to be stamped and formed, and at the same time, the extrusion spray part 10 is squeezed into the interior of the mold frame 1 and squeezed out. The lubricating oil stored in the bottom end of the extrusion spray part 10 inside the mold frame 1 is sprayed out from the spray port 11, and the buffer pad 9 is used to prevent the mold frame 1 and the extrusion spray part 10 from being squeezed and damaged. Then the hydraulic punch 16 drives the extension rod 13 and the stamping part 12 to reset, and the extrusion spray part 10 is reset by the action of pressure. The stamped chassis is driven by the electric push rod 6 installed on the side wall of the support seat 5 to push the unloading push plate 7 to move to the surface of the unloading table 4, thereby completing automatic unloading.
