Description

Technical Field

[0001] The utility model relates to the technical field of spring sheet processing, in particular to a spring sheet forming die. Background Art

[0002] A spring leaf is a part manufactured by a stamping process. It has functions such as energy storage, shock absorption, clamping, and measurement. It is easy to bend in one direction, but has greater tensile stiffness and bending stiffness in the other direction. The material used to make the spring leaf usually needs to have a high elastic limit, fatigue limit, impact toughness, and good heat treatment performance. Commonly used materials include carbon spring leaf steel, alloy spring leaf steel, stainless steel spring leaf, copper alloy, etc. During the processing of the spring leaf, a forming mold needs to be used to press and bend the spring leaf to form the desired shape.

[0003] During the extrusion and bending process, the existing spring sheet forming mold is prone to produce debris due to bending, which will cause the debris to adhere to the material. During the next bending process, the thickness of the debris will affect the bending angle, resulting in the bending effect of the spring sheet being different from the desired effect. To this end, in response to the above defects, the present application proposes a spring sheet forming mold. 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 , Figure 2 and Figure 4 The utility model provides a technical solution: comprising a shell 1 and a water pump 16, the upper wall of the shell 1 is penetrated by a cylinder 2, and the telescopic end of the cylinder 2 is connected to a mold body 3, a cleaning box 14 is installed behind the inner lower wall of the shell 1, and a filter plate 15 is arranged inside the cleaning box 14, the water pump 16 is located at the lower part of the cleaning box 14, and the water outlet end of the water pump 16 is connected to a water pipe 17, and a nozzle 18 is installed at one end of the water pipe 17 away from the water pump 16, and the cleaning box 14, the filter plate 15, the water pump 16, the water pipe 17 and the nozzle 18 constitute a cleaning structure;

[0021] After each bending step, the material is moved to the cleaning box 14 by a robot, and then the material is cleaned by water sprayed from the nozzle 18, so that the debris on the material is washed away and no foreign matter is adhered to the material, thereby facilitating the bending work of the equipment and preventing the equipment from being affected by foreign matter during operation.

[0022] like Figure 2 As shown, an electric slide rail 4 is installed at the front end of the inner lower wall of the housing 1, and a manipulator 5 is installed at the upper end of the electric slide rail 4;

[0023] The manipulator 5 grabs and moves the material, thereby facilitating the continuous operation of the equipment. The electric slide rail 4 can transport the manipulator 5, so that the manipulator 5 can carry the material to the next step of the process.

[0024] like Figure 3 As shown, the positioning structure is located at the position where the manipulator 5 stops loading, and the number of positioning structures is the same as the number of loading points. The positioning structure is composed of a connecting ring 6, a vertical column 7, a gear rod 8, a traction spring 9, a telescopic spring 10, a telescopic slider 11, a telescopic rod 12 and an electromagnet 13. The vertical column 7 is arranged inside the connecting ring 6, the gear rod 8 is connected to one side of the connecting ring 6, the traction spring 9 is connected to the upper and lower sides of the gear rod 8, and the telescopic spring 10 is installed inside the gear rod 8, the telescopic slider 11 is connected to one side of the telescopic spring 10, and the telescopic slider 11 is connected to the side of the telescopic slider 11 away from the telescopic spring 10. The electromagnet 13 is installed on the side of the telescopic rod 12 away from the telescopic slider 11;

[0025] The shift rod 8 and the telescopic rod 12 can block the movement of the manipulator 5, thereby blocking and positioning the displacement of the manipulator 5, so that the equipment manipulator 5 can accurately grab or put down the material, thereby facilitating the equipment to accurately load and unload materials. The electromagnet 13 can pull and fix the shift rod 8 after the two shift rods 8 are reset, to prevent the shift rod 8 from shaking, and also to prevent the shift rod 8 from shaking due to collision during the positioning process, which affects the positioning effect.

[0026] Working principle: First, the material is placed into the mold by the manipulator 5, and then the mold body 3 is driven by the cylinder 2 to close the mold, so as to bend the material. After the first bend is completed, the material is grabbed by the manipulator 5, and then the material bent for the first time is moved to the cleaning box 14, and the water pump 16 is turned on. Water is transported to the nozzle 18 through the water pipe 17 to clean the material. After the material is cleaned, the material is transported to the next step through the electric slide rail 4 and the manipulator 5. During the transportation process, the manipulator 5 is blocked and positioned by the gear lever 8 and the telescopic rod 12, so that the manipulator 5 can be accurately moved. Make sure to place the material at the second bending position of the mold, and perform the second bending according to the above steps. After the second bending process is completed, the robot 5 continues to move and pushes the gear rod 8, so that the gear rod 8 rotates around the vertical column 7 through the connecting ring 6, so that the gear rod 8 makes way for the passage of the robot 5. When the robot 5 has passed, the gear rod 8 can be reset by the traction spring 9, and the telescopic spring 10 can pull the telescopic slider 11 when the gear rod 8 rotates, so that the telescopic rod 12 contracts a certain distance in the gear rod 8, so that the two electromagnets 13 will not collide when the gear rod 8 is reset.
