Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping template with a positioning auxiliary structure. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts. The stamping template is an important part of the stamping die.

[0003] Publication number "CN211965642U" provides a guide limiter for a stamping template in a multi-link stamping machine. The guide limiter for a stamping template in a multi-link stamping machine is manufactured by optimizing the overall design of the upper frame, the lower frame, the limiter column and the guide column. This solves the problem that the stamping template is prone to slight deviation when the multi-link stamping machine is stamping the workpiece. When stamping the workpiece with high stamping precision requirements, the stamping failure is easy to occur due to the slight deviation of the stamping template, and the workpiece is seriously scrapped. The workpiece with high stamping precision requirements cannot be stamped.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] The guide limit device for the stamping template can solve the problem that the stamping template is prone to slight deviation, but the lower frame in the guide limit device cannot firmly fix the lower template, which causes the lower template to easily shake slightly due to stamping vibration during use, thereby reducing the stamping accuracy of the stamping template. In addition, the limit pipe column and guide column in the guide limit device have poor wear resistance, which requires staff to frequently maintain or replace the limit pipe column and guide column during use, and its practicality needs to be improved.

[0028] A fixing component 5 is provided at the lower end of the fixed die seat 3, and the fixing component 5 is used to install and fix the fixed die seat 3 to prevent the fixed die seat 3 from displacement or shaking during use. An auxiliary limiting component 6 is provided on the side of the stamping template 2, and the auxiliary limiting component 6 is used to perform auxiliary limiting on the stamping template 2 to prevent the stamping template 2 from offset during use, thereby ensuring the stamping accuracy of the stamping template 2.

[0029] The fixing assembly 5 includes a fixing base plate 52, a connecting screw 53, a fixing nut 54, a limiting block 55 and a limiting groove 56. The fixing base plate 52 is installed on the upper end surface of the support platform 4, and the fixing base plate 52 will fix the fixed mold base 3. Connecting screws 53 are symmetrically installed on the left and right sides of the fixed base plate 52. The connecting screws 53 and the limiting blocks 55 are connected by welding.

[0030] A positioning through groove 57 is provided inside the fixed base plate 52, and the positioning through groove 57 matches the fixed mold base 3. The positioning through groove 57 not only facilitates the fixed mold base 3 to be located inside the fixed base plate 52, but also enables the fixed base plate 52 to fix the fixed mold base 3 to avoid displacement of the fixed mold base 3 during use. Mounting through holes 58 are symmetrically provided on the left and right sides of the fixed base plate 52, and the mounting through holes 58 match the connecting screws 53. The mounting through holes 58 facilitate the connecting screws 53 to be inserted into the fixed base plate 52.

The limiting groove 56 will guide the limiting block 55.

[0031] Embodiment 2:

[0032] On the basis of embodiment one, the limit rod 62 in this embodiment will limit and guide the extension seat 64 through the wear-resistant inner sleeve 65, so that the extension seat 64 can limit and guide the stamping template 2 through the follower frame 66, thereby ensuring the stamping accuracy of the stamping template 2, and the wear-resistant inner sleeve 65 made of wear-resistant ceramic and the limit rod 62 made of wear-resistant steel have good wear resistance, thereby extending the maintenance period of the extension seat 64 and the limit rod 62.

[0033] The auxiliary limiting assembly 6 includes a limiting rod 62, an extension seat 64, a wear-resistant inner sleeve 65 and a follower frame 66. The follower frame 66 is installed on the upper end of the stamping template 2. The follower frame 66 is connected to the extension seat 64 by welding. The follower frame 66 will drive the extension seat 64 to move up and down. The left and right end surfaces of the follower frame 66 are symmetrically provided with extension seats 64. The extension seat 64 facilitates the limiting rod 62 to limit and guide the follower frame 66. A wear-resistant inner sleeve 65 is installed inside the extension seat 64. The wear-resistant inner sleeve 65 matches the limiting rod 62. The wear-resistant inner sleeve 65 is made of wear-resistant ceramic. The wear-resistant inner sleeve 65 made of wear-resistant ceramic has high hardness and good wear resistance, thereby improving the service life of the extension seat 64.

[0034] A limit rod 62 is arranged inside the wear-resistant inner sleeve 65, and the limit rod 62 is connected to the fixed bottom plate 52 by welding. The limit rod 62 and the fixed bottom plate 52 are both made of wear-resistant steel.

A first reinforcing rib 61 is fixedly connected to the lower side of the annular side of the limit rod 62. The first reinforcing rib 61 makes the connection between the limit rod 62 and the fixed bottom plate 52 more stable. A second reinforcing rib 651 is fixedly connected to the upper end surface of the extension seat 64. The second reinforcing rib The piece 651 makes the connection between the extension seat 64 and the follower frame 66 more stable. The right end face of the extension seat 64 is provided with an internal threaded hole 641, and a fixing screw 63 is installed inside the internal threaded hole 641. The internal threaded hole 641 and the fixing screw 63 are convenient for fixing the wear-resistant inner sleeve 65 inside the extension seat 64 to prevent the wear-resistant inner sleeve 65 from loosening during use. The upper end face of the follower frame 66 is symmetrically provided with fixing through holes 661 on both sides. The fixing through holes 661 facilitate external bolts to install the follower frame 66 on the outer surface of the stamping template 2.

[0035] Working principle: During the use of the fixed die seat 3, the connecting screw 53, the fixing nut 54 and the limit block 55 will fix the fixed base plate 52 on the upper end surface of the support platform 4, so that the fixed base plate 52 can position the fixed die seat 3 through the positioning groove 57 to prevent the fixed die seat 3 from displacement or shaking during use. When the installer loosens and disassembles the fixing nut 54 with the help of an external wrench, the fixed base plate 52 can be moved upward and disassembled, and the fixed die seat 3 can be disassembled and replaced at this time; during the use of the punching machine body 1 driving the punching template 2 to move up and down, the limit rod 62 will limit and guide the extension seat 64 through the wear-resistant inner bushing 65, so that the extension seat 64 can be extended. The extension seat 64 limits and guides the stamping template 2 through the follower frame 66, so as to avoid the stamping template 2 from deflecting during the up and down movement, thereby ensuring the stamping accuracy of the stamping template 2. At the same time, the wear-resistant inner sleeve 65 made of wear-resistant ceramic can increase the service life of the extension seat 64, and the limit rod 62 made of wear-resistant steel has good wear resistance, thereby extending the maintenance cycle of the extension seat 64 and the limit rod 62. In the later use process, when the wear-resistant inner sleeve 65 needs to be replaced, the installer only needs to loosen and disassemble the fixing screw 63 with the help of an external wrench, and then the wear-resistant inner sleeve 65 can be moved up, disassembled and replaced.
