Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die for punching holes in sheet metal. Background Technology

[0002] In the field of sheet metal processing, punching is an important process operation. However, traditional sheet metal punching dies have some obvious shortcomings in practical applications.

[0003] Traditional stamping dies are not effective in fixing sheet metal. During the stamping process, the sheet metal is prone to positional displacement, resulting in low punching accuracy and affecting product quality. At the same time, traditional dies are cumbersome in fixing and separating sheet metal, lacking convenience and reliability, which reduces production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a stamping die for punching sheet metal, comprising: a floating joint block; a force equalizing plate, the top of which is fixedly connected to the bottom of the floating joint block by bolts; a top plate, the top of which is fixedly connected to the bottom of the force equalizing plate by bolts; a cover plate, the top of which is fixedly connected to the bottom of the top plate by bolts; a partition plate, the top of which is fixedly connected to the bottom of the top plate by bolts; a stamping assembly, the top of which is fixedly connected to the bottom of the partition plate by bolts; a sliding assembly, the outer wall of which is slidably connected to the inner wall of the stamping assembly by bolts; a lower die assembly, the top of which is fixedly connected to the top of the sliding assembly; the stamping assembly includes an upper die plate, the inner wall of which is slidably connected to an unloading plate via an inner hard guide post, and the outer wall of the inner hard guide post is slidably connected to the inner wall of the upper die plate; a punch is slidably connected to the inner wall of the unloading plate, and a suction cup is fixedly connected to the bottom of the punch.

[0005] Preferably, the inner wall of the unloading plate is slidably connected with an inner hard guide post, the top of the inner hard guide post is fixedly connected to the inner wall of the cover plate, the inner wall of the partition is fixedly connected to the outer wall of the inner hard guide post, and the inner wall of the top plate is fixedly connected with an equal-height screw sleeve, the height of the equal-height screw sleeve is equal to the height of the inner hard guide post.

[0006] Preferably, the outer wall of the equal-height screw steel sleeve is fixedly connected to the inner wall of the top plate, a pre-compression spring is fixedly connected to the inner wall of the top plate, the top of the unloading plate contacts the bottom of the upper template, the upper template restricts the position of the unloading plate, and a positioning top rod is fixedly connected to the inner wall of the unloading plate.

[0007] Preferably, the end of the pre-compression spring away from the top plate is fixedly connected to the top of the upper template, a PIN cylinder sleeve is fixedly connected to the inner wall of the top plate, the inner wall of the PIN cylinder sleeve is slidably connected to the outer wall of the top of the positioning rod, and the height of the positioning rod is equal to the height of the PIN cylinder sleeve.

[0008] Preferably, the lower mold assembly includes a lower template, on the top of which a sheet body is mounted. The top of the lower template contacts the bottom of the unloading plate, the top of the sheet body contacts the bottom of the punch, and the top of the sheet body contacts the bottom of the suction cup, which restricts the position of the sheet body.

[0009] Preferably, the sliding component includes limiting posts, and four sets of limiting posts are provided. The top of each set of limiting posts is slidably connected to a linear bearing, which limits the position of the limiting post. The outer wall of the linear bearing is fixedly connected to the inner wall of the upper template, and the bottom of the limiting post is fixedly connected to the top of the lower template.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting a unique stamping component, allows the suction cup at the bottom to adsorb the sheet metal after the punch contacts the sheet metal body, ensuring the stability of the sheet metal position during the stamping process and improving stamping accuracy. At the same time, the combination of the internal through groove of the punch, the top plate cavity and the external air pipe enables effective control of the suction cup adsorption force, which facilitates the fixing and separation of the sheet metal and improves the convenience and reliability of the stamping operation.

[0012] 2. This utility model, by setting a pre-compression spring, is compressed and accumulates elastic potential energy when the top plate moves continuously downward. The equal-height screw steel sleeve and PIN cylinder sleeve respectively restrict the position of the upper die equal-height screw and the positioning ejector rod. The inner hard guide post on the cover plate and partition plate further restricts the position of the stripper plate. These structures work together to ensure the stability and safety of the stamping process and effectively prevent stamping quality problems caused by uneven pressure or positional deviation.

[0013] 3. By setting a limiting post, the upper and lower templates are connected by the limiting post, and a linear bearing is set on the upper template to assist the movement of the limiting post. This makes the relative position of the upper and lower templates more accurate during the stamping process, improves the stamping precision and consistency, reduces the scrap rate caused by template misalignment, and improves the overall production efficiency and product quality.

[0014] 4. By setting up a floating joint block, the force equalizing plate below the floating joint block can disperse the pressure of the floating joint block, so that the pressure is evenly distributed on the top plate, avoiding excessive local pressure from damaging the equipment, extending the service life of the equipment, and reducing maintenance costs.

The top of component 3 is fixedly connected; the stamping component 5 includes an upper template 59, the inner wall of the upper template 59 is slidably connected to an unloading plate 54 via an inner hard guide post 55, and the outer wall of the inner hard guide post 55 is slidably connected to the inner wall of the upper template 59. The inner wall of the unloading plate 54 is slidably connected to a punch 56, and the bottom of the punch 56 is fixedly connected to a suction cup 58, which is adsorbed onto the plate body 42 by the suction cup 58, thereby restricting the position of the plate body 42. The inner wall of the unloading plate 54 is slidably connected to an inner hard guide post 55, the top of the inner hard guide post 55 is fixedly connected to the inner wall of the cover plate 7, the inner wall of the partition plate 8 is fixedly connected to the outer wall of the inner hard guide post 55, and the inner wall of the top plate 6 is fixedly connected to an equal-height screw steel sleeve 51.

[0026] The outer wall of the equal-height screw steel sleeve 51 is fixedly connected to the inner wall of the top plate 6. A pre-compression spring 53 is fixedly connected to the inner wall of the top plate 6. The top of the unloading plate 54 is in contact with the bottom of the upper template 59. A positioning push rod 57 is fixedly connected to the inner wall of the unloading plate 54. The end of the pre-compression spring 53 away from the top plate 6 is fixedly connected to the top of the upper template 59. A PIN cylinder sleeve 52 is fixedly connected to the inner wall of the top plate 6. The inner wall of the PIN cylinder sleeve 52 is slidably connected to the outer wall of the top of the positioning push rod 57. The PIN cylinder sleeve 52 restricts the position of the positioning push rod 57.

[0027] The lower mold assembly 4 includes a lower mold plate 41, on the top of which a plate body 42 is mounted. The top of the lower mold plate 41 contacts the bottom of the unloading plate 54, the top of the plate body 42 contacts the bottom of the punch 56, and the top of the plate body 42 contacts the bottom of the suction cup 58. Air is blown back into the suction cup 58 through the air pipe on the top plate 6, thereby releasing the restriction on the plate body 42. The external sliding assembly 3 includes a limiting post 31, which is provided in four sets. The top of each set of limiting posts 31 is slidably connected to a linear bearing 32. The outer wall of the linear bearing 32 is fixedly connected to the inner wall of the upper mold plate 59, and the bottom of the limiting post 31 is fixedly connected to the top of the lower mold plate 41.

[0028] Working principle:

[0029] In use, the sheet metal body 42 is first placed on the lower die assembly 4. Then, the external stamping head is installed on the floating joint block 1, so that the external stamping head can drive the stamping assembly 5 at the bottom of the top plate 6 to move downward through the floating joint block 1. The force equalizing plate 2 below the floating joint block 1 is used to disperse the pressure of the floating joint block 1, so that the pressure is distributed on the top plate 6. After the stamping assembly 5 contacts the lower die assembly 4, it performs pre-pressing work on the sheet metal body 42. Then, under the continuous push of the external stamping head, it drives the stamping assembly 5 to move downward along the sliding assembly 3, so as to complete the stamping work on the sheet metal body 42.

[0030] After the punch 56 in the stamping assembly 5 contacts the sheet metal body 42, the suction cup 58 at the bottom of the punch 56 also adheres to the sheet metal body 42. The air in the suction cup 58 moves to the external air pipe through the through groove inside the punch 56 and the cavity in the top plate 6, so that the suction cup 58 holds the sheet metal body 42. Then, as the top plate 6 continues to move downward, the upper die equalizing screw on the stripper plate 54 will press the pre-compression spring 53 upward, so that the pre-compression spring 53 is compressed and deformed, thus accumulating elastic potential energy. The equalizing screw steel sleeve 51 in the top plate 6 is used to limit the position of the upper die equalizing screw. The top plate 6 is also provided with a PIN cylinder sleeve 52, which is used to limit the position of the positioning ejector rod 57. The inner hard guide post 54 on the cover plate 7 and the partition plate 8 is used to further limit the position of the stripper plate 55, thereby limiting the sliding position of the stripper plate 54.

[0031] After the punch 56 continues to move downward and cuts the plate body 42 on the lower template 41, the plate body 42 is punched into a round piece corresponding to the punch 56. After the punching is completed, the external punch head moves upward, and the suction cup 58 moves upward synchronously under the drive of the punch 56, thereby driving the round piece to move upward and separating the plate body 42 from the round piece. After the plate body 42 is removed, air can be blown back into the suction cup 58 through the air pipe on the top plate 6 to release the restriction on the round piece.

[0032] The upper template 59 and the lower template 41 are connected by a limiting post 31, and a linear bearing 32 is fixed on the upper template 59 to assist the movement of the limiting post 31.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
