[0002] Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting, which are used to fix things, process things, and decorate. Stamping dies are a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the required parts.

The extrusion cylinder 83 is electrically connected to the external power supply to provide power for the extrusion cylinder 83.

[0035] The present invention provides an improved hardware stamping die capable of stamping different styles, and its working principle is as follows:

[0036] First, when using this device, first place the device in the work area, and then connect the device to an external power source to provide the power required for the device to work;

[0037] Secondly, when the recessed template 9 is installed in a limited position, the staff first drives the two sets of limiting slides 32 to slide in the inner groove of the limiting slide 31 by controlling the stretching cylinder 38. At this time, the sliding action of the two sets of limiting slides 32 is extended and limited by the limiting sleeve 37. Then the staff places the recessed template 9 on the top of the limiting slide 32 and applies a thrust to the recessed template 9, so that the recessed template 9 drives the slotted sphere 364 to rotate with the displacement. At the same time, the gravity squeezes the slotted sphere 364, so that it moves downward under the action of the elastic member 363, so that the slotted sphere 364 moves downward and contacts the lubricating oil (butter) inside the oil storage channel 362, and smears it on the bottom of the concave plate 9 by rotating, thereby reducing the wear of the concave plate 9 and the limiting slide 32 caused by friction. When the concave plate 9 moves and contacts the positioning plate 367, it reaches the working position. Then, the air flow inside the lifting cylinder 34 can be controlled to be extracted, so that the lifting cylinder 34 contracts and the clamping plate 35 moves downward under the action of gravity to clamp the concave plate 9, which is beneficial to improve the clamping effect of different types of molds while improving the clamping efficiency.

[0038] Third, when installing and clamping the convex template 10, the staff inserts the permanent magnet plate 86 on the left and right sides of the convex template 10 through the positioning rod 87, and then fixes the permanent magnet plate 86 and the convex template 10 to the bottom of the second T-shaped slide plate 84 through the hexagonal screw 85. At the same time, the two sets of slide plates 82 are pushed to the left and right directions by controlling the extrusion cylinder 83, and the second T-shaped slide plate 84 is placed into the inner groove at the bottom of the slide plate 82, and a thrust is applied to the convex template 10, so that the convex template 10 is displaced in the front and back directions on the top of the slide plate 82 under the limiting action of the second T-shaped slide plate 84. When the second T-shaped slide plate 84 slides and presses against the rear side of the inner groove of the slide plate 82, the concave template 9 and the convex template 10 complete the positioning action, which is conducive to improving the rapid installation and positioning effect of the convex template 10.

[0039] Fourth, during the stamping process, the high-precision electric push rod 71 can be controlled to drive the mounting shell 72 and the air jet 76 to perform height adjustment. At this time, the quick connector 77 is used to provide a connection between the air jet 76 and the external pipeline, and the transmission hand wheel 74 and the threaded section 75 are rotated to make the threaded installation between the threaded section 75 and the mounting shell 72 to adjust the angle of the coil ring 73 and the air jet 76. The air jet 76 is attracted by the magnetism of the coil ring 73, so that the air jet 76 can be displaced to different heights to perform blowing actions at different angles, which is beneficial to improving the air jet blowing effect on the concave template 9 and the convex template 10.

[0040] The present invention provides a stamping die for hardware parts of different styles through improvement. The limiting slide 31 and the stretching cylinder 38 provide a limiting and driving effect for the sliding of the limiting slide 32. Then, the clamping plate 35 is supported and limited by the return spring 33 and the lifting cylinder 34, so that the clamping plate 35 can cooperate with the limiting slide 32 to clamp, which is beneficial to improving the clamping effect of different types of molds. The lubricating oil is sent into the oil storage channel 362 through the oil injection hole 365, and the slotted ball 364 is limited by the elastic member 363, so that the slotted ball 364 moves up and down to send the lubricating oil to the surface of the concave template 9, which is beneficial to improving the clamping effect of the concave mold. The plate 9 is convenient for installation and limiting, and the wear of the concave template 9 and the limiting slide 32 caused by friction is reduced. The installation shell 72 and the air jet 76 are driven by the high-precision electric push rod 71 to adjust the height, and the coil ring 73 and the air jet 76 are adjusted in angle by the threaded installation of the transmission hand wheel 74 and the threaded segment 75 with the installation shell 72, which is beneficial to improve the adjustment effect of the jet blowing angle. The first T-shaped slide 81 and the second T-shaped slide 84 slide in both directions, and the convex template 10 is driven to slide by the permanent magnet plate 86 and the positioning rod 87 under the driving action of the extrusion cylinder 83, which is beneficial to improve the rapid installation and positioning of the convex template 10.
