Description

Technical Field

[0001] The utility model relates to the field of metal processing, in particular to a precision hardware molding die. Background Art

[0002] Precision hardware is usually used in precision instruments, equipment and machinery. These parts are usually made of metal materials and have complex shapes and strict size requirements. During processing, a metal strip of sufficient length is required for stamping operations, and a complex stamping process is carried out continuously. During the stamping process of the metal strip, since the metal strip is actually very thin, the physical impact pressure will cause the metal strip to move during stamping. At the same time, the metal strip is prone to bending and stacking during the transportation process, which will cause creases on the surface of the metal strip, affecting the final quality of the product.

[0003] Therefore, a kind of precision hardware molding die is now developed for the problems mentioned above. Utility Model Content

[0004] In order to overcome the shortcomings of the existing device in the process of stamping the metal strip, since the metal strip is actually very thin, the metal strip will be displaced due to the physical impact pressure during stamping, and the metal strip is also prone to bending and stacking during transportation, which will cause creases on the surface of the metal strip and affect the final quality of the product, the utility model provides a precision hardware molding die.

[0005] The technical solution of the utility model is: a precision hardware molding die, including a base, a concave die connected to the top of the base, guide columns connected to the four corners of the top of the concave die, a convex die slidably arranged between the guide columns, and a flattening mechanism for guiding the feeding of the metal strip and extruding it flat at the same time is arranged between the concave die and the convex die.

[0006] Furthermore, the flattening mechanism includes a mounting frame, which is connected to the right side of the concave mold, a long guide roller is rotatably provided on the mounting frame, a sliding roller is slidably and rotatably provided on the right side of the mounting frame, two second springs are connected between the sliding roller and the mounting frame, a mounting block is connected to the right side of the convex mold, a rotating roller is rotatably connected to the mounting block, and two torsion springs are connected between the rotating roller and the adjacent mounting block.

[0007] Furthermore, it also includes a receiving mechanism, which includes a guide frame, the guide frame is connected to the left side of the concave mold, a bidirectional screw is rotatably connected to the guide frame, two sliding blocks are slidably connected to the guide frame, and multiple short guide rollers are rotatably provided on the sliding blocks.

[0008] Furthermore, a transfer seat is installed on the male mold through bolts.

[0009] Furthermore, two limiting plates for pressing and limiting the metal strip are slidably connected to the male mold, and two first springs are connected between the limiting plates and the male mold.

[0010] Furthermore, the front end of the bidirectional screw rod is connected with a rotating handle.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The utility model uses a sliding roller to press and limit the metal belt to be processed, so that the metal belt can be stably conveyed, and during the stamping process, the metal belt is always pressed flatly through the cooperation between the rotating roller and the torsion spring, avoiding the bending and stacking of the metal belt during the conveying process.

[0013] 2. After the metal strip is stamped, the utility model rotates and adjusts the bidirectional lead screw according to the width of the metal strip, so that the sliding blocks are close to each other along the guide frame. As the sliding blocks continue to approach, the short guide rollers will fit with the edges on both sides of the metal strip, thereby achieving limited guidance for the metal strip, making it convenient for the operator to receive and roll the metal strip after the stamping process.

DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0019] Example 1

[0020] A precision hardware molding die, such as Figure 1As shown, it includes a base 1, a concave mold 2 is connected to the top of the base 1, and guide columns 4 are connected to the four corners of the top of the concave mold 2. A convex mold 3 for stamping is slidably arranged between the guide columns 4, and a transfer seat is installed on the convex mold 3 by bolts. Two limit plates 5 for pressing and limiting the metal strip are slidably connected to the convex mold 3, and two first springs 6 are connected between the limit plates 5 and the convex mold 3. A flattening mechanism 7 for guiding the feeding of the metal strip and extruding it flat is arranged between the concave mold 2 and the convex mold 3.

[0021] like Figure 1 and Figure 2 As shown, the flattening mechanism 7 includes a mounting frame 71, the mounting frame 71 is connected to the right side of the concave mold 2, a long guide roller 72 for supporting and guiding the metal strip is rotatably provided on the mounting frame 71, a sliding roller 73 is slidably and rotatably provided on the right side of the mounting frame 71, two second springs 74 are connected between the sliding roller 73 and the mounting frame 71, a mounting block 75 is connected to the right side of the male mold 3, a rotating roller 76 is rotatably connected to the mounting block 75, and two torsion springs 77 are connected between the rotating roller 76 and the adjacent mounting block 75.

[0022] It should be noted that when performing precision hardware processing, a metal strip of sufficient length is required for stamping operations, and a complex stamping process is continuously performed. First, the sliding roller 73 is pulled upward so that the second spring 74 is compressed, and then the metal strip is transported to the left along the long guide roller 72. Then the sliding roller 73 is released. Under the action of the second spring 74, the sliding roller 73 will slide downward along the mounting frame 71, so that the sliding roller 73 presses and limits the metal strip, and then the metal strip is transported. During the transportation process, the long guide roller 72 will guide the movement of the metal strip, and then the rotating part at the top of the male mold 3 is rotated. The seat is connected to the hydraulic cylinder, and then the hydraulic cylinder is started to drive the male mold 3 to move downward, so that the male mold 3 and the female mold 2 cooperate to perform stamping operations on the metal strip. As the male mold 3 moves downward, the limit plate 5 will also move downward synchronously and contact with the metal strip to achieve extrusion limitation of the metal strip and avoid displacement of the metal strip during the stamping process. At the same time, as the male mold 3 moves downward, the mounting block 75 will also move downward synchronously, so that the rotating roller 76 contacts with the metal strip. Relying on the rotation of the rotating roller 76 and the cooperation of the torsion spring 77, the metal strip is guided smoothly to avoid bending of the metal strip, so that the metal strip can always fit with the long guide roller 72.

[0023] Example 2

[0024] On the basis of Example 1, Figure 1 and Figure 3As shown, it also includes a receiving mechanism 8, which includes a guide frame 81. The guide frame 81 is connected to the left side of the concave mold 2. A bidirectional screw rod 82 is rotatably connected to the guide frame 81. A rotating handle is connected to the front end of the bidirectional screw rod 82. Two sliding blocks 83 are slidably connected to the guide frame 81, and a plurality of short guide rollers 84 are rotatably provided on the sliding blocks 83.

[0025] It should be noted that after the stamping process of the metal strip is completed, the bidirectional screw 82 is adjusted by rotating according to the width of the metal strip, so that the sliding blocks 83 are close to each other along the guide frame 81. As the sliding blocks 83 continue to approach, the short guide rollers 84 will fit with the edges on both sides of the metal strip, thereby achieving limited guidance for the metal strip, making it easier for the operator to receive and roll the metal strip after the stamping process.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
