[0002] Sheet metal is a metal processing technology that mainly performs comprehensive cold processing on metal sheets, including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming, etc. In the process of sheet metal production, bending machines are usually required for bending. Bending machine molds are tools used by bending machines to form and process sheet materials. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the formed material, and is used to make the blank into a part with a specific shape and size under the pressure of the bending machine.

[0003] The existing bending mold is usually composed of an upper mold driven downward by a driving part, a lower mold fixed on the top of a platform, a supporting structure and other components. The upper mold is used to press down the metal part on the lower mold to achieve bending of the metal part.

[0023] Example

[0024] See also Figure 1-Figure 3 , a bending die that is easy to replace as shown in the figure includes:

[0025] A sliding groove 101 is provided on the top of the platform 100, a sliding plate 110 is provided inside the sliding groove 101, a support column 130 is fixed to the top of the platform 100 by bolts, and a driving member 131 is provided on the side wall of the support column 130;

[0026] In some embodiments, the driving member 131 uses a common model of electric push rod on the market. The electric push rod is a device that combines an electric motor with a linear push rod and is used to provide linear motion in a mechanical system. The electric push rod is usually composed of a motor, a transmission system, and a push rod. The working principle of the electric push rod is to drive the transmission system through the motor to make the push rod produce linear motion, thereby prompting the upper mold 133 to move downward.

[0027] A rotating disk 132 is provided at the power output end of the driving member 131. The rotating disk 132 is composed of two upper and lower rotating disks that are rotatably connected. The two rotating disks are rotatably connected through a rotating column in the middle. An upper mold 133 is provided at the bottom of the rotating disk 132.

[0028] The lower mold 200 is arranged on the top of the sliding plate 110, and a rotating column 201 matched with the sliding plate 110 is arranged at the bottom of the lower mold 200, and a bending groove 210 matched with the upper mold 133 is arranged at the top of the lower mold 200, and a locking hole 211 matched with the telescopic column 310 is opened on the side wall of the lower mold 200, and a side locking strip 220 is fixed to the side wall of the lower mold 200 by bolts;

[0029] The limit member 300 is fixed to the top of the platform 100 by bolts. The side wall of the limit member 300 is equipped with a telescopic column 310. The telescopic column 310 uses a common electric push rod on the market. When the electric push rod is extended, the push rod enters the locking hole 211 or the clamping hole 221 to lock the lower mold 200. The telescopic column 310 is electrically connected to the control switch 320. The control switch 320 uses a common forward and reverse switch on the market.

[0030] Specifically, a positioning hole 120 is formed at the top of the sliding plate 110 , and a magnet sheet is disposed inside the positioning hole 120 .

[0031] Furthermore, a positioning block 121 that matches the side wall of the side locking strip 220 is provided at the top of the positioning hole 120 . The positioning block 121 is made of a common iron block and can be magnetically attracted to the inside of the positioning hole 120 .

[0032] Furthermore, a plurality of engaging holes 221 for engaging with the telescopic columns 310 are formed on the side wall of the side locking strip 220 .

[0033] Furthermore, the telescopic column 310 is fixed to the top of the platform 100 by bolts.

[0034] It is worth noting that the control switch 320 is fixed to the side wall of the platform 100 by bolts.

[0035] It is noteworthy that the upper mold 133 is matched with the top of the lower mold 200 .

[0036] In addition, the electrical components and electrical equipment mentioned above all use external power supplies. The circuits, electronic components and modules involved in the utility model are all prior art, and those skilled in the art can fully implement them. Needless to say, the content protected by the utility model does not involve improvements to the internal structure and methods.

[0037] Working principle: After the sliding plate 110 of the lower mold 200 is pushed and installed in cooperation with the sliding groove 101, the lower mold 200 is matched between the telescopic columns 310 at both ends of the platform 100, and then the telescopic columns 310 are extended and pass through the bottom of the limiter 300 to lock with the locking hole 211, so that the lower mold 200 can be conveniently installed, thereby facilitating the convenient replacement of the lower mold 200 of the bending mold, eliminating the trouble of using tools to tighten the bolts to install and disassemble the lower mold 200, saving manpower and increasing the convenience of using the bending mold; during installation When the lower mold 200 is moved, the positioning block 121 can be removed. At this time, the sliding plate 110 can be held to rotate the top lower mold 200 90 degrees, and then the lower mold 200 can be installed. At this time, the telescopic column 310 can be extended to cooperate with the clamping hole 221 of the side locking strip 220 to lock the lower mold 200, and when the upper mold 133 is rotated, the rotating disk 132 can be used to rotate the upper mold 133 90 degrees, so that the lower mold 200 and the upper mold 133 can be rotated and adjusted, which improves the applicability of the bending mold to various angle requirements when used, and facilitates the use of the bending mold.
