Description

Technical Field

[0001] The utility model relates to the technical field of hole-turning dies, in particular to a water tank press-forming hole-turning die. Background Art

[0002] The punching die is a special die that is mainly used to make round holes or special-shaped holes on sheet materials. This die is usually used for products that require solid round holes or special-shaped holes, such as printed products, mold manufacturing, etc. The working principle of the punching die is to turn the hole edge of the sheet material into a vertical edge through the punching pressure of the die, thereby creating a specific shape. In mold processing and assembly, the punching technology can be used to make the positioning holes required in the mold or the holes that ensure accurate fit between parts.

[0003] During the processing of the sink, some of its parts need to be punched. The existing punching die can only process the holes. It cannot complete multiple operations at the same time during the pressing process, including punching, bending and punching, which increases the time for machine die change. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , 2 As shown in Figures 3 and 4, the utility model provides a technical solution: a water tank profiling and hole-turning die, comprising: an upper template 3, a first punch 9 and a second punch 12 for turning holes are fixedly connected to the bottom of the upper template 3, a first pressing plate 7 is slidably provided on the outer side of the first punch 9, a second pressing plate 10 is slidably provided on the outer side of the second punch 12, a first spring 8 is provided on the top of the first pressing plate 7 and the second pressing plate 10, a shaping block 11 is fixedly connected to the bottom of the second pressing plate 10, and a sliding hole 13 for the movement of the second punch 12 is provided in the middle of the shaping block 11; a lower template 1, a first supporting plate 14 and a second supporting plate 16 are respectively provided on the top of the lower template 1 corresponding to the positions of the first pressing plate 7 and the second pressing plate 10, and a shaping groove 17 matched with the shaping block 11 is provided on the top of the shaping groove 17.

[0021] It should be noted that the utility model places the workpiece to be processed on the top of the first support plate 14 and the second support plate 16, and drives the upper template 3 to move downward through the extrusion equipment. During the movement, the shaping block 11 first contacts the workpiece. Under the action of the first spring 8, the shaping block 11 cooperates with the shaping groove 17 to punch and bend the workpiece into shape. Then, under the continued stamping of the extrusion equipment, the first punch 9 passes through the first pressing plate 7 and cooperates with the first punch hole 15, so as to perform hole turning under the stamping action of the first punch 9. At the same time, the second punch 12 penetrates the second pressing plate 10 and the shaping block 11 from the sliding hole 13, and cooperates with the hole corresponding to the shaping groove 17 to turn the bent workpiece. After the stamping is completed, when the upper template 3 is raised, the ejector pin 18 lifts the workpiece under the action of the second spring 2.

[0022] See also Figure 2 As shown, a plurality of limiting rods 6 are slidably connected inside the upper mold plate 3 , and the first pressing plate 7 and the second pressing plate 10 are both fixedly connected to the limiting rods 6 .

[0023] It should be noted that the setting of the limit rod 6 of the utility model ensures that the first pressure plate 7 and the second pressure plate 10 can only move vertically, avoiding horizontal movement or tilting, thereby improving the accuracy and stability during the processing; since the limit rod 6 ensures the vertical movement of the pressure plate, the stable motion trajectory provided by the limit rod 6 ensures the repeatability and consistency of each stamping process.

[0024] See also Figure 1 , 2 As shown, a first punch hole 15 is provided at a position of the first support plate 14 corresponding to the first punch 9 .

[0025] It should be noted that the first punch 9 of the utility model is made of two metal rods of different thicknesses, and the two connecting parts are truncated cone-shaped structures. The top of the first punch 15 is provided with a countersunk hole. The size and position of the first punch 9 and the first punch 15 are adapted to ensure that the two can be matched correctly during the punching process; when the first punch 9 is pressed down, the material is pushed into the first punch 15, and the hole is turned through plastic deformation.

[0026] See also Figure 3 , 4 As shown, the bottom of the second support plate 16 is slidably connected to a ejector pin 18 , and the bottom of the ejector pin 18 is fixedly connected to a second spring 2 .

[0027] It should be noted that the sliding connection between the second support plate 16 and the ejector pin 18 of the utility model allows the ejector pin to move freely in the vertical direction; when the mold of the ejector pin 18 is closed, the workpiece presses it into the second support plate 16, and when the punching force is applied to the workpiece and then released, the spring helps the ejector pin return to its original position, and the second spring 2 and the ejector pin 18 lift the workpiece to achieve demolding.

[0028] See also Figure 1 , 2 As shown, the tops of the first support plate 14 and the second support plate 16 are fixedly connected to limit plates, the first pressing plate 7 and the second pressing plate 10 are provided with slots corresponding to the positions of the limit plates, the four bottom corners of the upper template 3 are fixedly connected to guide rods 5, the outer side of the guide rods 5 is slidably connected to the guide tube 4, and the guide tube 4 is fixedly connected to the lower template 1.

[0029] It should be noted that the limit plate of the utility model is used to determine the placement position of the workpiece so that the position to be processed corresponds to the stamping position. The four corners of the bottom of the template 3 are fixed with guide rods 5, and the outer side of the guide rods is connected to the guide tube 4 by sliding. The guide tube is fixed to the lower template 1, ensuring that the upper template can maintain stability and precise vertical alignment during the pressing or rising process to reduce deviation.
