Description

Technical Field

[0001] The utility model relates to the technical field of bending machine dies, and specifically relates to a split upper die structure for a bending machine. Background Technique

[0002] A bending machine is a machine that can bend thin plates with the help of bending dies. The bending dies usually include an upper die and a lower die. Among them, the upper die is usually fixedly connected to the upper slide plate of the bending machine through a pressing plate of the bending machine.

[0003] When bending a sheet with a special-shaped notch, there are usually multiple upper dies. The multiple upper dies are arranged side by side. When in use, it is necessary to install or remove the upper die at the corresponding position according to the notch position of the sheet with a special-shaped notch, and it is necessary to repeatedly tighten or loosen the bolts, which is time-consuming and laborious, inconvenient to use, and it is easy to cause uneven pressing force of the pressing plate due to inconsistent bolt locking force, thereby affecting the quality of the bent product.

[0004] As disclosed in a bending machine upper die installation structure proposed in Chinese Patent CN208853548U, through the upper slide plate and the upper die, with the front side of the upper slide plate facing the operator and the opposite side being the rear side, a rear clamping plate is rotatably connected to the rear side of the lower end of the upper slide plate. A front clamping plate is detachably connected to the rear clamping plate, and a hanging strip is arranged on the side of the front clamping plate facing the rear clamping plate. The upper end of the upper die has a hanging groove cooperating with the hanging strip, and the upper end of the upper die is clamped between the front clamping plate and the rear clamping plate. A fastening plate for fixing the rear clamping plate is rotatably connected to the front side of the lower end of the upper slide plate. By rotatably connecting the rear clamping plate to the upper slide plate, the rear clamping plate and the upper die as a whole can be rotated to the rear side of the upper slide plate to be hidden, and then reset when needed, without repeatedly installing and disassembling the upper die, which is more convenient to use and not prone to inconsistent locking forces of each upper die, and the product quality is relatively good.

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0027] Embodiment 1:

[0028] A split bending machine upper die structure includes an installation rod 1, an installation structure is connected to the outer surface of the installation rod 1, a positioning structure is installed at both left and right ends of the installation structure, and a limiting structure is installed in the middle of the installation structure.

[0029] The installation structure includes a disassembly and assembly unit and a positioning and connection unit. The disassembly and assembly unit includes an upper die clamping block 101. In the middle of the bottom surface of the upper die clamping block 101, a connecting plate 102 is connected. On the top surface of the connecting plate 102, a fixing bolt 103 is installed. The positioning and connection unit includes an arc-shaped die 104. Near the left and right ends in the middle of the top surface of the arc-shaped die 104, sliders 105 are installed. On the top of the sliders 105, guide grooves 106 are provided.

[0030] The outer surface of the fixing bolt 103 is threadedly connected to the internal thread of the threaded hole opened on the top surface of the connecting plate 102. The bottom end of the outer surface of the fixing bolt 103 is threadedly connected to the internal thread of the threaded groove opened on the top surface of the arc-shaped die 104. The outer surface of the slider 105 is slidably connected to the internal convex-shaped sliding groove opened in the middle of the bottom surface of the guide groove 106. The guide groove 106 is fixedly installed at the left and right ends in the middle of the bottom surface of the connecting plate 102.

[0031] Through the setting of the installation structure, the connecting plate 102 and the arc-shaped die 104 are connected by using the fixing bolt 103, so as to facilitate the disassembly and assembly of the arc-shaped die 104. At the same time, during installation, the guiding and positioning of the slider 105 and the guide groove 106 are utilized to make the installation more accurate and convenient.

[0032] When installing the arc-shaped die 104, first, the sliding connection between the outer surface of the slider 105 and the inner wall of the convex-shaped sliding groove opened in the middle of the bottom surface of the guide groove 106 is utilized to quickly guide and connect and position the arc-shaped die 104. Then, by rotating the fixing bolt 103 to be threadedly connected to the internal thread of the threaded groove opened on the top surface of the arc-shaped die 104, the quick installation and positioning of the arc-shaped die 104 are realized. And when it is necessary to disassemble, assemble and replace the arc-shaped die 104, it is also more convenient and fast.

[0033] Embodiment 2:

[0034] On the basis of Embodiment 1, the positioning structure includes a fixing plate 201. Near the bottom end in the middle of the left side of the fixing plate 201, a lower rivet 202 is installed. Near the top end in the middle of the left side of the fixing plate 201, an upper rivet 203 is installed. The outer surface of the lower rivet 202 is clamped in the internal installation groove opened in the middle of the left and right ends of the connecting plate 102. The outer surface of the upper rivet 203 is clamped in the internal installation groove 1 opened in the middle of the side far away from each other of the left and right upper die clamping blocks 101 near the bottom end.

[0035] The limiting structure includes a positioning post 301. A first limiting pin 302 is installed near the bottom end of the outer surface of the positioning post 301, and a second limiting pin 303 is installed near the top end of the outer surface of the positioning post 301. The outer surface of the positioning post 301 is slidably connected to the inner wall of a circular hole groove opened in the middle of the top surface of the connecting plate 102. The outer surface of the first limiting pin 302 is slidably connected to the inner wall of a limiting hole opened on the outer surface of the positioning post 301. The outer surface of the second limiting pin 303 is slidably connected to the inside of a first limiting hole opened near the top end of the outer surface of the positioning post 301. The outer surface of the first limiting pin 302 abuts against the bottom surface of the connecting plate 102.

[0036] Through the installation of the positioning post 301, the first limiting pin 302 and the second limiting pin 303, and by using the slidable connection between the positioning post 301 and the inside of the circular hole groove opened on the top surface of the arc-shaped mold 104, it is convenient to position the installation position of the arc-shaped mold 104. At the same time, during use, by the limitation of the first limiting pin 302 and the second limiting pin 303, it is convenient to perform point support on the force received by the arc-shaped mold 104, thereby ensuring the safety of using the arc-shaped mold 104.

[0037] When installing and connecting the overall upper mold structure, the fixing plate 201 is installed on the left and right sides of the installation structure by using the lower rivets 202 and the upper rivets 203. By using the clamping connection between the lower rivets 202 and the left and right ends of the connecting plate 102, and the clamping connection between the upper rivets 203 and the left and right upper mold clamping blocks 101, the installation and connection of the upper mold structure are further fixed by using the fixing plate 201. At the same time, the stability of the installation of the connecting plate 102 inside the rectangular groove in the middle of the bottom surface of the upper mold clamping block 101 is effectively increased. Then, by using the clamping connection between the positioning post 301 and the inside of the positioning groove opened on the top surface of the arc-shaped mold 104, the positioning and limitation during the installation of the arc-shaped mold 104 are realized. When the arc-shaped mold 104 is stressed during use, by the limitation of the first limiting pin 302 and the second limiting pin 303 on the positioning post 301, and the abutment between the first limiting pin 302 and the connecting plate 102, the force points of the arc-shaped mold 104 are shared to ensure the safety during the use of the arc-shaped mold 104.
