Description

Technical Field

[0001] This utility model relates to the field of progressive drawing die technology, and more specifically, to a bidirectional progressive drawing die guide block. Background Technology

[0002] Biaxial stretching progressive die is a continuous stamping die designed specifically for thin material processing. It achieves biaxial stretching and forming through multi-station collaboration. In order to ensure that the strip can move forward stably on the progressive die without deviation, guide blocks are usually set on both sides of the bottom die to guide the strip.

[0003] The existing progressive die guide block has a relatively simple structure. The part that contacts the strip is a planar structure. When guiding the strip on the die, the edge of the strip will slide against the guide block. Since the edge of the strip is usually quite sharp, long-term sliding contact with the guide block can easily cause wear on the guide block, resulting in a short service life. In addition, the existing guide blocks are usually fixed to both sides of the bottom die with screws, so the distance between the guide block and the bottom die cannot be adjusted. It can only guide strips of a fixed width, resulting in low applicability of the guide block. Utility Model Content

[0004] This invention provides a bidirectional stretching progressive die guide block, which solves the technical problems in the prior art where the edge of the strip slides into contact with the guide block, easily causing wear on the guide block, and the inability to adjust the distance between the guide block and the bottom die, resulting in low applicability.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A bidirectional stretching progressive die guide block includes a die platform and a stretching bottom die. Supports are provided on both sides of the stretching bottom die on the die platform. Several sets of guide rollers are rotatably connected to the support facing one side of the stretching bottom die. The several sets of guide rollers are arranged in a row on the support. A driving assembly is provided between the die platform and the two sets of supports on both sides of the stretching bottom die. The driving assembly can make the two sets of supports on both sides of the stretching bottom die simultaneously receive opposite driving forces.

[0007] Furthermore, the drive assembly includes a bidirectional screw rotatably disposed inside the mold table, threaded sleeves threaded onto both ends of the bidirectional screw, and a connecting rod connecting the threaded sleeves and the bracket.

[0008] Furthermore, the end of the bidirectional screw extends out of the outside of the mold table and is fixedly connected to a knob, the surface of which is provided with anti-slip texture.

[0009] Furthermore, slide rails are provided on both sides of the bottom position of the support on the mold platform, and sliders are slidably connected on the slide rails, with the sliders fixedly connected to the bottom end of the support.

[0010] Furthermore, both the bracket and the guide roller are made of aluminum alloy, and the outer surface of the guide roller is also nested with a rubber sleeve.

[0011] Furthermore, the mold platform is provided with scale lines, and the bottom of the bracket is provided with a pointer pointing to the scale lines.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by rotating the guide rollers set on the brackets, when the strip is pushed forward along the direction of the stretching die, the edge of the strip can roll into contact with the guide rollers, thereby guiding the strip on the stretching die while preventing contact wear between the edge of the strip and the brackets. Furthermore, when the width of the strip placed on the die changes, the distance between the two sets of brackets and the stretching die can be adjusted in time by the drive assembly, so that the guide rollers on the brackets can closely abut against the edges of strips of different widths to guide the strip. Therefore, the two sets of brackets can adapt to strips of different widths, effectively improving the applicability of the guide block. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-5 A bidirectional progressive die guide block includes a die table 1 and a stretching bottom die 2. Supports 3 are arranged on both sides of the stretching bottom die 2 on the die table 1. Several sets of guide rollers 4 are rotatably connected to one side of the support 3 facing the stretching bottom die 2. The sets of guide rollers 4 are arranged in rows on the support 3. When the strip material is advanced forward on the stretching bottom die 2, the two edges of the strip material can roll into contact with the guide rollers 4. A drive assembly is arranged between the die table 1 and the two sets of supports 3 on both sides of the stretching bottom die 2. In this structure, the drive assembly includes a bidirectional screw 5 rotatably disposed inside the die table 1. The threaded sleeves 6 are threaded onto both ends of the bidirectional screw 5, and the connecting rod 7 connects the sleeves 6 and the bracket 3. The threads at both ends of the bidirectional screw 5 are in opposite directions. When the bidirectional screw 5 is rotated, it can drive the two sets of sleeves 6 in opposite directions. At this time, under the drive of the two sets of sleeves 6, the two sets of brackets 3 located on both sides of the stretching die 2 will be driven in opposite directions at the same time, so that the two sets of brackets 3 move towards or away from the stretching die 2 at the same time, thereby adjusting the distance between the two sets of brackets 3 and the stretching die 2 at the same time.

[0023] In use, the two sets of supports 3 on both sides of the stretching die 2 are moved simultaneously by the drive component, thereby adjusting the distance between the two sets of supports 3 and the stretching die 2. This ensures that the guide rollers 4 on the two sets of supports 3 can just abut against the edge of the strip on the stretching die 2. When the strip moves forward along the stretching die 2, the edge of the strip can roll into contact with the guide rollers 4, thus guiding the strip on the stretching die 2 while preventing contact wear between the edge of the strip and the supports 3. Furthermore, when the width of the strip placed on the die changes, the distance between the two sets of supports 3 and the stretching die 2 can be adjusted in time by the drive component, so that the guide rollers 4 on the supports 3 can closely abut against the edge of the strip of different widths to guide the strip. Therefore, the two sets of supports 3 can adapt to strips of different widths, effectively improving the applicability of the guide block.

[0024] For further details, please refer to Figure 1-5 The end of the bidirectional screw 5 extends out of the outside of the mold table 1 and is fixedly connected to a knob 8. The surface of the knob 8 is provided with anti-slip texture, and the user can easily control the bidirectional screw 5 to rotate by holding the knob 8.

[0025] For further details, please refer to Figure 1-5 The mold platform 1 is provided with slide rails 9 on both sides at the bottom position of the support 3. Slider 10 is slidably connected to the slide rails 9 and fixedly connected to the bottom of the support 3. Since the slider 10 can always slide horizontally along the direction of the slide rail 9, when the support 3 is driven to move, the slide rail 9 and the slider 10 can guide the movement of the support 3, so that the support 3 can always maintain a horizontal trajectory and move without deflection under the driving action.

[0026] For further details, please refer to Figure 1-5 Both the bracket 3 and the guide roller 4 are made of aluminum alloy, which has high strength and corrosion resistance, is not easily deformed and has a long service life. In addition, the outer surface of the guide roller 4 is also nested with a rubber sleeve 11, which can improve the wear resistance of the surface of the guide roller 4 and further prevent the edge of the material strip from causing wear on the surface of the guide roller 4.

[0027] For further details, please refer to Figure 1-5 The mold table 1 has scale lines 12 distributed on it, and the bottom of the support 3 is provided with a pointer 13 pointing to the scale lines 12. When the user controls the support 3 to move, the distance between the support 3 and the stretching bottom mold 2 can be determined by observing the position of the pointer 13 pointing to the scale line 12, so as to facilitate the precise adjustment of the distance between the two.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
