Description

Technical Field

[0001] The utility model relates to the technical field of die punches, in particular to a floating structure of a punching die punch. Background Technique

[0002] In the design of punching dies, the selection of punching punches is crucial. The punch needs to achieve precise and efficient up-and-down movement within the die fixing plate to ensure the accuracy and stability during the punching process. However, traditional special-shaped punch designs often lack a floating structure, which easily causes the punch to frequently fall under the influence of gravity in the punch fixing plate, and then perform a punching reset movement.

[0003] In the punch design without a floating structure, after the punching is completed, due to the action of its own gravity, the punch will quickly fall to the initial position of the punch fixing plate. This rapid falling process will not only generate impact noise, but also cause wear to the precision components of the die, thereby affecting the service life of the die.

[0004] Moreover, the gravity fall and reset movement of the punch will directly lead to a reduction in the guiding accuracy. The guiding accuracy is a very crucial parameter in punching dies, which determines the movement trajectory and positioning accuracy of the punch during the punching process. When the punch frequently performs gravity fall and reset movements, its movement trajectory and positioning accuracy will be severely affected, resulting in problems such as dimensional deviation and shape distortion of the punched products. Therefore, it is necessary to develop a floating structure for a punching die punch. Content of the Utility Model

[0030] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the implementation manners of the present utility model in detail in conjunction with the accompanying drawings.

[0031] Please refer to Figures 1-7 , which shows a schematic structural diagram of an implementation manner of a floating structure of a punch of a stamping die. Please refer to Figures 1-7 , and a detailed introduction to a floating structure of a punch of a stamping die will be given.

[0032] A floating structure of a punch of a stamping die includes a mounting block 100. A first inclined surface 110 with a higher left and a lower right is provided in the middle of the top wall of the mounting block 100. A vertical punch 120 is detachably provided at the bottom of the mounting block 100. Vertical buffer springs 130 are symmetrically arranged on the left and right of the punch 120 at the bottom of the mounting block 100;

[0033] On the top of the mounting block 100, a mounting rail 200 is arranged along the upper surfaces of the mounting block 100 and the first inclined surface 110. A regulating block 210 is slidably arranged in the left-right direction on the top of the mounting rail 200. In the middle of the bottom wall of the regulating block 210, a second inclined surface 220 with a higher left side and a lower right side is arranged. Chute grooves 230 are arranged on the front and rear side walls of the mounting rail 200. On the right side of the bottom of the regulating block 210, side plates 240 protrude around the front and rear. The distance between the front and rear side plates 240 is equal to the overall width of the mounting rail 200. On one side of the four side plates 240 close to the chute grooves 230, mounting rods 250 protrude. The rod bodies of the mounting rods 250 are arranged in the chute grooves 230 with a clearance, and a runner 260 is arranged on the rod body of each mounting rod 250. The runner 260 rolls in the chute grooves 230 in a fitting manner. By arranging the side plates 240 and the runners 260 rolling in the chute grooves of the side plates 240, the regulating block 210 can only move horizontally left and right relative to the mounting block 100. By adding a buffer spring 130 between the punch 120 and the punch holder (the punch holder is not shown in the figure), the punch 120 will not fall immediately after stamping is completed, but stay above the punch holder until the next stamping starts to move.

[0034] Furthermore, buffer blocks 140 are arranged at the upper and lower ends of the two buffer springs 130 respectively. The outer diameter of the buffer blocks 140 is larger than that of the buffer springs 130. The upper buffer block 140 is fixed to the bottom of the mounting block 100. Compared with the buffer spring 130, the buffer block 140 has a larger contact area with the surface of the punch holder at its bottom, so it is more stable.

[0035] Further, a rectangular groove 300 is opened at the bottom of the front side wall of the mounting block 100. A rectangular mounting head 310 is fixedly arranged at the top end of the punch 120. The mounting head 310 is fitted and slid into the groove 300. A transverse mounting cavity 320 is opened in the housing of the mounting block 100 behind the groove 300. A transverse double-headed positive and negative lead screw 330 is rotatably arranged in the inner cavity of the mounting cavity 320. Movable plates 340 are screwed and driven on the threads on both sides of the double-headed positive and negative lead screw 330. The two movable plates 340 are symmetrically arranged left and right with respect to the mounting head 310. A transverse insertion rod 350 is protruded on the side of the two movable plates 340 close to the mounting head 310. Insertion holes 360 for the insertion rod 350 to fit into are opened on the left and right side walls of the mounting head 310. A limiting groove 380 for the left and right horizontal movement of the movable plate 340 is opened in the housing of the mounting block 100. The upper and lower walls of the movable plate 340 are respectively in contact with the upper and lower walls in the groove of the limiting groove 380. The right end of the double-headed positive and negative lead screw 330 extends and rotatably penetrates through the right side wall of the mounting block 100, and a knob 370 is arranged at the right end of the double-headed positive and negative lead screw 330. When the punch 120 needs to be replaced, the double-headed positive and negative lead screw 330 is rotated by the knob 370, so that the two movable plates 340 gradually move away from each other, and the insertion rod 350 is withdrawn from the hole of the insertion hole 360. Then, when the punch 120 and the mounting head 310 are slid out of the groove 300 in the forward direction, the punch 120 can be disassembled.

[0036] Further, when the rear side wall of the mounting head 310 is in contact with the rear side wall in the groove of the groove 300, the insertion rod 350 and the insertion hole 360 are collinearly aligned. When assembling other punches 120, the mounting head 310 is inserted into the groove 300. When the rear side wall of the mounting head 310 is in contact with the rear side wall in the groove of the groove 300, the insertion rod 350 and the insertion hole 360 are collinearly aligned. Then, the double-headed positive and negative lead screw 330 is rotated in the reverse direction, so that the two movable plates 340 gradually approach each other, driving the insertion rod 350 to insert into the hole of the insertion hole 360, and completing the rapid installation of the punch 120.

[0037] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any way. The exhaustive description of the combinations in this specification is omitted only for the consideration of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
