[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] Example 1, please refer to Figure 1-5This utility model provides an auxiliary mold for bending metal sheets, including a lower mold base 1, a first positioning frame 101, a first positioning block 102, a first positioning mold 103, a first storage groove 104, a first positioning strip 105, a lower bending mold 106, a sliding rod 107, an upper mold 2, a second positioning frame 201, a second positioning block 202, a second positioning mold 203, a second storage groove 204, a second positioning strip 205, an upper bending mold 206, a buffer block 3, a buffer plate 301, a buffer pad 302, a slider 303, a sliding groove 304, a telescopic rod 305, and a spring 306. The first positioning mold 103 is fixed inside the lower mold base 1. The first positioning mold 103 and... A first storage groove 104 is provided at the connection of the lower bending mold 106. A first positioning strip 105 is fixed inside the first storage groove 104. The first positioning strip 105 is slidably connected to the lower bending mold 106. The cross-section of the first positioning strip 105 is an inverted isosceles trapezoidal structure. A groove with the same cross-sectional shape as the first positioning strip 105 is provided at the connection between the lower bending mold 106 and the first positioning strip 105. In this way, the position of the lower bending mold 106 can be fixed by the first positioning strip 105, so as to prevent the lower bending mold 106 from vertically separating from the first positioning mold 103. When bending the metal plate through the lower bending mold 106, the lower bending mold 106 is prevented from shaking up and down.
[0025] Specifically, such as Figure 1 and Figure 2 As shown, a first positioning frame 101 is provided on one side of the lower mold base 1. A first positioning block 102 is provided at the connection between the side of the first positioning frame 101 and the lower mold base 1. The first positioning block 102 is inserted and connected to the lower mold base 1 and the first positioning frame 101, and the first positioning block 102 is screwed to the lower mold base 1. The first positioning frame 101 can limit the side of the lower bending mold 106 to prevent the lower bending mold 106 from shaking, which would affect the bending of the metal plate. By removing the first positioning block 102, the first positioning frame 101 can be removed, and then the lower bending mold 106 can be slid out from one side, which is convenient for replacing the lower bending mold 106.
[0026] Specifically, such as Figure 1 and Figure 2As shown, the first positioning frame 101 is slidably connected to the lower mold base 1. Four sets of lower bending molds 106 are distributed on the side of the first positioning mold 103. The lower bending molds 106 are slidably connected to the first positioning mold 103. Four sets of sliding rods 107 are fixed on the top of the lower mold base 1. The spacing of the sliding rods 107 is greater than the width of the lower bending molds 106. The spacing of the sliding rods 107 is also greater than the width of the upper bending mold 206. This can avoid the sliding rods 107 from affecting the metal plate passing by and facilitate the bending of the metal plate. The upper mold 2 is slidably connected to the top of the sliding rods 107.
[0027] Specifically, such as Figure 2 and Figure 3 As shown, a second positioning mold 203 is fixed inside the upper mold 2. A second storage groove 204 is provided at the connection between the second positioning mold 203 and the upper bending mold 206. A second positioning strip 205 is fixed inside the second storage groove 204. The second positioning strip 205 is slidably connected to the upper bending mold 206. The cross-section of the second positioning strip 205 is an inverted isosceles trapezoidal structure. A groove with the same cross-sectional shape as the second positioning strip 205 is provided at the connection between the lower bending mold 106 and the second positioning strip 205. The second positioning strip 205 can limit the position of the upper bending mold 206 vertically, preventing the upper bending mold 206 from separating from the second positioning mold 203, and facilitating the bending of metal sheets by the upper bending mold 206.
[0028] Specifically, such as Figure 3 and Figure 4 As shown, four sets of upper bending molds 206 are distributed on the side of the second positioning mold 203. The upper mold 2 is provided with a second positioning frame 201 on the same side as the first positioning frame 101. A second positioning block 202 is provided at the connection between the side of the second positioning frame 201 and the upper mold 2. The second positioning block 202 is inserted and connected to the upper mold 2 and the second positioning frame 201, and the second positioning block 202 is screwed to the upper mold 2. After the second positioning block 202 is removed, the upper bending mold 206 can be taken out by sliding, which makes it easy to replace the upper bending mold 206 in use and facilitates bending metal plates into different styles.
[0029] Example 2, specifically, as follows Figure 3 , Figure 4 and Figure 5As shown, the second positioning frame 201 is slidably connected to the upper mold 2. A buffer block 3 is fixed inside the upper mold 2. A buffer plate 301 is provided on the top of the buffer block 3. A slider 303 is fixed at one end of the buffer plate 301 near the buffer block 3. A groove 304 is provided at the connection between the buffer block 3 and the slider 303. Two sets of telescopic rods 305 are fixed inside the groove 304. The telescopic rods 305 are slidably connected to the slider 303. A spring 306 is provided on the outside of the telescopic rods 305. The spring 306 can buffer the lower bending mold 106 when it is connected to it.
[0030] Specifically, such as Figure 4 and Figure 5 As shown, buffer pads 302 are distributed at the bottom of the buffer block 3 and the connection between the first positioning mold 103 and the buffer block 3. A set of second positioning strips 205 is also fixed in the middle of the top of the first positioning mold 103. The buffer pads 302 can buffer the buffer plate 301 with the lower bending mold 106, reducing the pressure wear between the lower bending mold 106 and the first positioning mold 103.
[0031] In use, this embodiment of the application sets a first positioning mold 103 and distributes four sets of lower bending molds 106 on the side of the first positioning mold 103. The four sets of lower bending molds 106 are provided with different bending grooves. After disassembling the first positioning block 102, the first positioning frame 101 is removed from the lower mold base 1. The lower bending mold 106 can be taken out from the first storage groove 104 of the first positioning mold 103 by sliding and replaced with the lower bending mold 106 on the buffer plate 301 to meet different metal plate bending requirements.
[0032] The second positioning mold 203 is also provided with four sets of upper bending molds 206 distributed on the side. By removing the second positioning block 202 and separating the second positioning frame 201 from the upper mold 2, the position of the upper bending mold 206 can be adjusted to correspond with the lower bending mold 106. This allows the mold to bend the metal plate while meeting four different bending requirements. The different lower bending molds 106 and upper bending molds 206 are stored inside the lower mold base 1 and the upper mold 2 for easy adjustment and use.
[0033] The set of lower bending dies 106 used on the lower die base 1 is set on the buffer plate 301. In this way, when bending the metal plate, the buffer pad 302 of the buffer plate 301 and the sliding telescopic compression spring 306 of the slider 303 and the groove 304 can play a buffering role with the first positioning die 103, protecting the first positioning die 103 and the lower bending die 106. In this way, the auxiliary die for bending metal plates is completed. It should be noted that this utility model is an auxiliary die for bending metal plates.
