[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Embodiment 1

[0029] See also Figures 1 to 5 The utility model provides a short material drawing device, comprising: a workbench 1, a drawing die set, a material clamping device 6 and a drawing drive device. The drawing die set comprises a male die 2, a female die 3, a mold clamping drive device 4 and a drawing drive plate 5. The drawing drive plate 5 is slidably mounted on the table of the workbench 1. The female die 3 and the mold clamping drive device 4 are both fixed on the drawing drive plate 5. The male die 2 is slidably mounted on the drawing drive plate 5 and connected to the mold clamping drive device 4. The mold clamping drive device 4 can drive the male die 2 to move toward the female die 3.

[0030] Among them, the male mold 2 can be used to place the short material 100 to be drawn. The short material 100 in this embodiment is a square tube with a certain length. When the mold driving device 4 drives the male mold 2 to dock with the female mold 3, the short material 100 on the male mold 2 can be inserted into the female mold 3.

[0031] Furthermore, the clamping device 6 is fixed on the workbench 1, and is used to clamp one end of the short material 100 passing through the female mold 3. The drawing drive device is used to drive the drawing die set to move, so that the short material 100 clamped by the clamping device 6 is drawn and formed under the cooperation of the male mold 2 and the female mold 3.

[0032] The male mold 2 in the utility model also acts as a jig. After the short material 100 to be drawn is manually placed on the male mold 2, the mold driving device 4 is used to drive the male mold 2 to connect with the female mold 3, so that the short material 100 passes through the female mold 3 and is clamped and fixed by the clamping device 6, and then the drawing drive device is used to drive the drawing die set to move. During the movement of the male mold 2 and the female mold 3, pressure is applied to the short material 100, thereby stretching it to obtain a desired shape. The overall structure of the drawing equipment is simple, the footprint is small, the operation is simple, and there is no need to train fixed operators. It can be used for small-batch production and as a backup equipment for existing fully automatic drawing equipment. It can be put into use when a failure or unstable material factors occur during the mass production of the existing fully automatic drawing equipment to ensure production progress. At the same time, the drawing equipment of the utility model is also convenient for providing effective trial production. In addition, the existing drawing equipment drives the material to move during the drawing process, and the drawing stability is poor. However, the short material 100 of the utility model is clamped and fixed by the clamping device 6, and the drawing drive device drives the male mold 2 and the female mold 3 to move to draw and form the short material 100. Compared with the existing technology, it can provide a better and more stable drawing and forming effect.

[0033] See also Figure 1 and Figure 2 The female mold 3 is fixed on the top of the drawing driving plate 5 through the female mold base 7, and is located between the male mold 2 and the clamping device 6. A drawing hole 301 is opened in the middle of the female mold 3, and the shape of the drawing hole 301 matches the shape of the short material 100 to be drawn and formed, and the drawing hole 301 is arranged opposite to the male mold 2.

[0034] It should be noted that the short material 100 in the present invention is headed (i.e. flattened) before drawing, so that one end of the short material 100 forms a head end 1001, and the size of the head end 1001 is smaller than the size of the drawing hole 301, so that the head end 1001 of the short material 100 can pass through the drawing hole 301. The male mold 2 is fixed to one end of the male mold fixing plate 201, and the male mold fixing plate 201 is roughly in the shape of a strip. When the short material 100 is sleeved on the male mold fixing plate 201 along one end where the male mold 2 is located, the head end 1001 of the short material 100 can be stopped by the male mold 2.

[0035] Furthermore, a mold closing motion slide rail 8 is provided on the drawing driving plate 5 along the drawing direction, a male mold base 9 is slidably mounted on the mold closing motion slide rail 8 via a slider, and the male mold 2 is fixedly connected to the male mold base 9 via a male mold fixing plate 201 .

[0036] like Figure 3 As shown, the mold closing drive device 4 adopts a cylinder, which is installed at the bottom of the drawing drive plate 5 and connected to the male mold base 9. The mold closing drive device 4 is used to drive the male mold base 9 to drive the male mold 2 to move along the mold closing motion slide rail 8.

[0037] Continue reading Figure 1 and Figure 2 A drawing motion slide rail 10 is arranged on the table surface of the workbench 1 along the drawing direction, and the drawing drive plate 5 is slidably installed on the drawing motion slide rail 10 through a plurality of sliders.

[0038] Optionally, the drawing drive device includes a drawing drive reduction motor 12 fixed on the drawing drive plate 5, a gear 13 fixed on the output shaft of the drawing drive reduction motor 12, and a rack 14 fixed on the workbench 1 along the drawing direction, and the gear 13 is meshed with the rack 14. When the drawing drive reduction motor 12 is working, the drawing drive plate 5 and the male mold 2 and the female mold 3 thereon can be driven to move along the drawing motion slide rail 10 under the transmission of the gear 13 and the rack 14.

[0039] See also Figure 4 The clamping device 6 includes two opposite clamping plates 601, a transmission mechanism and a clamping cylinder 602. The two clamping plates 601 are provided with serrations on one side facing each other. The clamping cylinder 602 is used to drive the two clamping plates 601 to move toward the middle through the transmission mechanism to clamp the head end 1001, and the serrations make the clamping more reliable.

[0040] Among them, the transmission mechanism is not an improvement of the present invention. It adopts the existing conventional technology and can be realized by a variety of structures. For example, by fixing sliders on the two clamping plates 601, the sliding direction is toward or away from each other, and the sliders are fixed with inner conical blocks. The clamping cylinder 602 is fixed with two outer conical blocks through the transmission rod, and the inclined surface of the outer conical block is in contact with the inclined surface of the inner conical block. When the clamping cylinder 602 pushes the outer conical block to extend, the outer conical block pushes the inner conical block to the middle, thereby driving the two clamping plates 601 to clamp the heading end 1001.

[0041] In addition, an oil spraying device is also installed on the workbench 1, and the oil spraying device includes an oil tank 15, an oil pump, and an oil spraying pipe 16 connected to the oil tank 15 through the oil pump. The oil spraying pipe 16 is installed on one side of the mother mold base 7 and is arranged toward the drawing hole 301. The mother mold base 7 is provided with an oil receiving groove 701, and an oil return pipe 17 is connected between the oil receiving groove 701 and the oil tank 15. During the drawing process, the lubricating oil in the oil tank 15 is sprayed on the short material 100 through the oil spraying pipe 16 by the oil pump, so that the friction is reduced during the drawing process, the short material 100 is avoided from being scratched, and the drawing effect is improved. At the same time, the lubricating oil sprayed by the oil spraying pipe 16 will be collected in the oil receiving groove 701, and returned to the oil tank 15 through the oil return pipe 17 to achieve recycling.

[0042] The working principle of this embodiment is as follows:

[0043] Figure 1The figure shows the initial state of the short material drawing device. First, the short material 100 to be drawn is manually mounted on the male mold 2 and the male mold fixing plate 201 until the leading end 1001 of the short material 100 is stopped by the male mold 2; then, the mold clamping drive device 4 drives the male mold 2 to move along the mold clamping motion slide rail 8, so that the male mold 2 and the female mold 3 are docked, and the leading end 1001 of the short material 100 passes through the drawing hole 301 of the female mold 3 and extends between the two clamping plates 601; then, the clamping cylinder 602 is driven The two clamping plates 601 move toward the middle to clamp and fix the leading end 1001; then, the drawing drive reduction motor 12 drives the gear 13 to rotate, and the gear 13 and the rack 14 drive the drawing drive plate 5 and the male mold 2 and the female mold 3 thereon to make a drawing movement, and finally the short material 100 is drawn and formed under the cooperation of the male mold 2 and the female mold 3; finally, the clamping cylinder 602 drives the two clamping plates 601 to open outward to release the leading end 1001, and the drawn short material 100 is taken away manually. The above steps can be repeated for small batch production.

[0044] Embodiment 2

[0046] It can be seen that the short material drawing equipment of the utility model utilizes the clamping drive device 4 to drive the male mold 2 and the female mold 3 to dock, so that the short material 100 mounted on the male mold 2 passes through the female mold 3 and is clamped and fixed by the clamping device 6, and then the drawing drive device is used to drive the drawing die set to move. During the movement of the male mold 2 and the female mold 3, pressure is applied to the short material 100, thereby stretching it to obtain the desired shape. The overall structure of the drawing equipment is simple, the footprint is small, the operation is simple, and there is no need to train fixed operators. It can be used for small-batch production and as a backup equipment for existing fully automatic drawing equipment. It can be put into use when a fault or unstable material factor occurs during the mass production of the existing fully automatic drawing equipment, so as to ensure the production progress and facilitate effective trial production. At the same time, the short material 100 of the utility model is clamped and fixed by the clamping device 6, and the male mold 2 and the female mold 3 are driven by the drawing drive device to move to draw and form the short material 100. Compared with the prior art, it can provide a better and more stable drawing and forming effect.
