Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, and in particular to a bending die head. Background Technology

[0002] Sheet metal refers to flat, rectangular building material sheets of standard size, used in the construction industry as components for walls, ceilings, or floors. It also often refers to metal sheets produced by forging, rolling, or casting. Bending dies can bend metal sheets. Existing bending dies require workers to remove the bent sheet after bending, which not only increases the number of steps involved in the bending process but also carries the risk of damage during removal, hindering sheet processing. Therefore, we propose a new bending die. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a bending die. This invention solves the problem that existing bending dies require workers to remove the bent sheet metal after bending, which not only increases the number of steps involved in the bending process but also carries the risk of damage during removal, hindering sheet metal processing.

[0004] A bending die head according to this utility model includes a U-shaped support base, a lower die base above the U-shaped support base, four guide rods arranged in a matrix above the lower die base, an upper die base sleeved on the upper end of the four guide rods, an installation groove in the middle of the lower end of the upper die base, an upper die fixedly installed in the installation groove, a die head in the middle of the lower part of the upper die base, a first die groove matching the die head in the middle of the upper end of the lower die base, a clearance groove below the first die groove in the lower die base, a plurality of equidistant movable rods inserted into the clearance groove in the lower die base, a push plate fixedly connected above the movable rods, and a spring sleeved between the movable rods and the push plate.

[0005] Preferably, the upper end of the push plate is provided with a second mold groove that matches the mold head.

[0006] Preferably, mounting plates are provided on both sides below the lower mold base, and the mounting plates are provided with a plurality of equally spaced mounting holes.

[0007] Preferably, an L-shaped connecting plate is provided in the middle of the upper part of the upper mold base, and two connecting holes are provided on both sides of the upper end of the L-shaped connecting plate.

[0008] Preferably, the upper mold has multiple equally spaced first threaded holes on both sides, and the upper mold base has a second threaded hole that matches the first threaded holes. Bolts are inserted into the first threaded holes and the second threaded holes.

[0009] Preferably, the bolt head is provided with an internal hexagon countersunk head.

[0010] Compared with related technologies, this utility model has the following beneficial effects:

[0011] This invention provides a bending die head. The die head enters the first die groove and squeezes the push plate, causing the push plate to enter the clearance groove. The spring is compressed under force. The first and second die grooves form a die groove structure that matches the die head. Through the cooperation between the die head and the first and second die grooves, the bending of the sheet metal can be completed. After the sheet metal is bent, the push plate can automatically eject the bent sheet metal under the action of the spring force. This die head has a simple structure, high bending accuracy, and the sheet metal can be automatically ejected after bending, which improves the bending efficiency of the sheet metal and effectively ensures the quality of the bent sheet metal product.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] like Figure 1-3As shown, this utility model is a bending die head, including a U-shaped support base 1, a lower die base 2 above the U-shaped support base 1, four guide rods 3 arranged in a matrix above the lower die base 2, an upper die base 4 sleeved on the upper end of the four guide rods 3, the guide rods 3 and the upper die base 4 being movably connected, so that the upper die base 4 can reciprocate vertically on the guide rods 3, an installation groove 5 is provided in the middle of the lower end of the upper die base 4, an upper die 6 is fixedly installed in the installation groove 5, a die head 7 is provided in the middle of the lower part of the upper die 6, a first die groove 8 matching the die head 7 is provided in the middle of the upper end of the lower die base 2, a clearance groove 9 is opened below the first die groove 8 of the lower die base 2, and a plurality of equidistant movable rods 10 are inserted into the clearance groove 9 of the lower die base 2, the movable rods 10 and The lower mold base 2 is movably connected, allowing the movable rod 10 to drive the push plate 11 to move vertically on the lower mold base 2. The upper part of the movable rod 10 is fixedly connected to the push plate 11. A spring 13 is sleeved between the movable rod 10 and the push plate 11. When the upper mold 6 drives the mold head 7 to move downward, the mold head 7 enters the first mold groove 8 and squeezes the push plate 11, causing the push plate 11 to enter the relief groove 9. The spring 13 is compressed by force, and the first mold groove 8 and the second mold groove 12 form a mold groove structure that matches the mold head 7. Through the mutual cooperation between the mold head 7 and the first mold groove 8 and the second mold groove 12, the bending of the sheet material can be completed. After the sheet material is bent, the push plate 11 can automatically push out the bent sheet material under the action of the spring force of the spring 13.

[0019] The upper end of the push plate 11 is provided with a second mold groove 12 that matches the mold head 7.

[0020] The lower mold base 2 is provided with mounting plates 14 on both sides below. The mounting plates 14 are provided with a plurality of equally spaced mounting holes 15, through which the lower mold base 2 can be fixedly installed.

[0021] An L-shaped connecting plate 16 is provided in the middle of the upper part of the upper mold base 4. Two connecting holes 17 are provided on both sides of the upper end of the L-shaped connecting plate 16. The upper mold base 4 can be fixedly installed through the connecting holes 17 on the L-shaped connecting plate 16.

[0022] The upper mold 6 has multiple equally spaced first threaded holes 18 on both sides. The upper mold base 4 has a second threaded hole 19 that matches the first threaded hole 18. Bolts 20 are inserted into the first threaded hole 18 and the second threaded hole 19. The bolts 20 have external threads that match the first threaded hole 18 and the second threaded hole 19. The bolts 20 enable a stable connection between the upper mold base 4 and the upper mold 6.

[0023] The bolt 20 has an internal hexagon countersunk head 21 at the screw head end, which makes it easier to install and remove the bolt 20.

[0024] Specifically, when the upper mold 6 moves the mold head 7 downward, the mold head 7 enters the first mold groove 8 and the mold head 7 squeezes the push plate 11, causing the push plate 11 to enter the relief groove 9. The spring 13 is compressed, and the first mold groove 8 and the second mold groove 12 form a mold groove structure that matches the mold head 7. Through the cooperation between the mold head 7 and the first mold groove 8 and the second mold groove 12, the bending of the sheet can be completed. After the sheet is bent, under the action of the spring force of the spring 13, the push plate 11 can automatically push out the bent sheet. The setting of the bolt 20 enables the upper mold base 4 and the upper mold 6 to be stably connected. The setting of the internal hexagon countersunk head 21 makes it easier to install and remove the bolt 20. The lower mold base 2 can be fixedly installed through the mounting hole 15, and the upper mold base 4 can be fixedly installed through the connecting hole 17 on the L-shaped connecting plate 16.
