Description

Technical Field

[0001] This utility model belongs to the field of wheel production technology, and in particular relates to a combined blanking die for steel wheel production. Background Technology

[0002] A wheel is a rigid device that holds the inner edge of a tire in place, supports the tire, and shares the load with it. The tire, rim, and spokes, when combined, are collectively referred to as a wheel. A wheel assembly consists of these two main components: the wheel and the tire. In the production of steel wheels, a blanking die is used to define the shape of the product for stamping.

[0003] Chinese Patent No. CN217617139U discloses a blanking die for steel wheel production, comprising a base, with fixed tubes fixedly connected to both sides of the top of the base, and a worktable arranged above it. Movable rods are fixedly connected to both sides of the bottom of the worktable, with the bottom ends of the movable rods inserted into the fixed tubes. Bolts are threaded to the top wall of the fixed tubes. Several positioning holes that mate with the bolts are formed on the surface of the movable rods. A limiting groove is formed on the top surface of the worktable. The limiting groove is circular, with a blanking port at its bottom. The die body is placed in the limiting groove. Several clamping mechanisms are arranged around the die body. A material collecting mechanism is arranged below the worktable.

[0004] The aforementioned patent has the following problems:

[0005] The aforementioned patent describes a clamping block that limits the die body. However, the clamping block is only held in place by a spring. When a collision occurs or the spring force decreases, it may loosen, causing the die body to fall off. This affects the use of the die body, and the disassembly of the die body requires manual operation. The automation level is low and it is not suitable for the current need for convenient disassembly. Therefore, we propose a combined blanking die for steel wheel production. Utility Model Content

[0006] The purpose of this invention is to provide a combined blanking die for the production of steel wheels, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a combined blanking die for steel wheel production, comprising:

[0008] The mounting box has a mounting groove on its top surface, and a die body is movably fitted inside the mounting groove. The bottom surface of the mounting groove has a material discharge port.

[0009] A limiting component is disposed within the mounting box and is used to limit the die body;

[0010] Multiple ejector holes are formed inside the bottom surface of the mounting groove. Support rods are fixedly installed at the four corners of the bottom surface of the mounting box. The same base plate is fixedly installed on the bottom surface of the support rods. The same lifting plate is slidably installed on the four support rods. Multiple ejector rods are fixedly installed on the top surface of the lifting plate. The multiple ejector rods correspond to the positions of the multiple ejector holes, and the multiple ejector rods are sleeved with the multiple ejector holes. The top ends of the multiple ejector rods are in contact with the bottom surface of the die body.

[0011] The lifting assembly is mounted on the base plate and is used to drive the lifting plate to rise and fall. After the two insert rods disengage from the two first insert holes, the motor can be started to drive the rotating shaft to rotate. When the rotating shaft rotates, the lifting plate will rise through the cooperation of the first connecting rod, the connecting seat, and the second connecting rod. After the lifting plate rises to a certain height, multiple ejector rods will pass through multiple ejector holes and contact the bottom surface of the die body. At this time, the ejector rods that continue to rise will push the die body out of the mounting groove, thereby realizing the quick disassembly of the die body and enhancing the convenience of disassembling the die body, which is quite practical.

[0012] In the above technical solution, the limiting component further includes two moving blocks, which are slidably installed in the mounting box. A rod is fixedly installed on each side of the two moving blocks that are close to each other. Second insertion holes are provided on both sides of the mounting groove, and the two second insertion holes are connected to the interior of the mounting box. First insertion holes are provided on both sides of the die body. The two rods are movably sleeved in the two first insertion holes and the two second insertion holes, respectively. When the two moving blocks are moved away from the die body to a certain position, the two rods will disengage from the two first insertion holes, thus releasing the limiting effect on the die body.

[0013] In the above technical solution, the limiting component further includes two circular rotating blocks, which are rotatably installed on both sides of the inner side of the mounting box. Protrusions are symmetrically installed on both sides of each of the two circular rotating blocks. Movable rods are rotatably installed on one side of each of the four protrusions. Two mounting seats are fixedly installed on the bottom surface of each of the two movable blocks. One end of each of the four movable rods is rotatably installed in one of the four mounting seats. When one of the movable blocks moves away from the die body, the four movable rods, in conjunction with the four protrusions, will drive the two circular rotating blocks to rotate. Simultaneously, the rotation of the two circular rotating blocks will drive the other movable block to move, thereby adjusting the distance between the two movable blocks.

[0014] In the above technical solution, an electric push rod is further fixedly installed on one side of the inner side of the mounting box. One end of the electric push rod is fixedly connected to one end of one of the moving blocks. When the electric push rod is activated, it drives one of the moving blocks away from the die body.

[0015] In the above technical solution, the lifting assembly further includes two side plates, which are fixedly installed on the top surface of the base plate. A common rotating shaft is rotatably installed between the two side plates. Multiple first connecting rods are fixedly installed on the rotating shaft. Multiple connecting seats are fixedly installed on the bottom surface of the lifting plate. A second connecting rod is rotatably installed in each of the multiple connecting seats. One side of each of the multiple second connecting rods is rotatably connected to one side of each of the multiple first connecting rods. When the rotating shaft rotates, the lifting plate will be driven to rise through the cooperation of the first connecting rods, connecting seats, and second connecting rods. After the lifting plate rises to a certain height, multiple ejector rods will pass through multiple ejector holes and contact the bottom surface of the die body. At this time, the ejector rods that continue to rise will push the die body out of the mounting groove, thereby realizing the quick disassembly of the die body.

[0016] In the above technical solution, a motor is further fixedly installed on one side of one of the side plates, and one end of the motor output shaft is fixedly connected to one end of the rotating shaft. The motor is started to drive the rotating shaft to rotate.

[0017] In the above technical solution, furthermore, multiple fixing plates are fixedly installed on both sides of the base plate, and each of the multiple fixing plates is provided with mounting holes. By setting multiple fixing plates and multiple mounting holes, the base plate can be conveniently installed and fixed.

[0018] The beneficial effects of this utility model are:

[0019] 1. The combined blanking die for steel wheel production, when disassembling the die body, activates an electric push rod to move one of the moving blocks away from the die body. When one of the moving blocks moves away from the die body, the four movable rods and four protrusions will drive two circular rotating blocks to rotate. When the two circular rotating blocks rotate, they will simultaneously drive another moving block to move, thereby adjusting the distance between the two moving blocks. After the two moving blocks move away from the die body to a certain position, the two insert rods will disengage from the two first insert holes, at which point the limitation on the die body is released.

[0020] 2. This combined blanking die for steel wheel production allows the motor to be started to drive the rotating shaft after the two insert rods disengage from the two first insert holes. When the rotating shaft rotates, the lifting plate will rise through the cooperation of the first connecting rod, the connecting seat, and the second connecting rod. After the lifting plate rises to a certain height, multiple ejector rods will pass through multiple ejector holes and contact the bottom surface of the die body. At this time, the ejector rods that continue to rise will push the die body out of the mounting slot, thereby realizing the quick disassembly of the die body and enhancing the convenience of disassembling the die body, which is quite practical.
