Description

Technical Field

[0001] The invention relates to the technical field of spinning processing, in particular to a reverse mold clamping device. Background Art

[0002] Spinning technology is also called metal spinning forming technology. It is a technology that rotates the spinning machine to make the force point change from point to line and from line to surface, and at the same time gives a certain pressure in a certain direction to make the metal material deform and flow along this direction to form a certain shape. Traditional spinning machines can only spin once in the same direction. After the semi-finished product, the mold needs to be changed and spun again, which reduces the production efficiency of the product. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a reverse mold clamping device, which does not require machine replacement or product disassembly. After the first spinning, another set of execution components pushes the second set of molds, and then reverse spinning is performed once to form the mold. The mold can also be fixed during the clamping process to prevent it from falling, thereby saving mold costs, spinning processing time, and mold replacement time, thereby achieving high efficiency and energy saving.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A reverse mold clamping device comprises a tail shaft of a spinning machine, a first mold is fixedly installed on one end of the tail shaft of the spinning machine, and a tail shaft connecting plate is fixedly installed on the other end; a second mold mounting plate located on one side of the first mold is movably sleeved on the tail shaft of the spinning machine, and a second mold is fixedly installed on one side of the second mold mounting plate; a hydraulic rear baffle and a hydraulic front baffle are inserted on the tail shaft of the spinning machine, and the hydraulic front baffle and the hydraulic rear baffle are fixedly installed on the tail stock of the spinning machine; a second hydraulic cylinder and a first hydraulic cylinder in opposite directions are fixedly installed between the hydraulic rear baffle and the hydraulic front baffle, and one end of the second hydraulic cylinder and the first hydraulic cylinder are both drivingly connected with a hydraulic telescopic shaft, one end of the hydraulic telescopic shaft on the second hydraulic cylinder is fixedly connected to one side of the second mold mounting plate, and one end of the hydraulic telescopic shaft on the first hydraulic cylinder is fixedly connected to the tail shaft connecting plate.

[0006] As a preferred technical solution of the present invention, a connecting support plate located between the hydraulic front baffle plate and the second mold mounting plate is mounted on the tail shaft of the spinning machine, and the hydraulic telescopic shaft at one end of the second hydraulic cylinder is movably connected to the connecting support plate.

[0007] As a preferred technical solution of the present invention, a guide rod is movably inserted between the hydraulic rear baffle, the hydraulic front baffle and the connecting support plate, one end of the guide rod is fixedly connected to one side of the second mold mounting plate, and the other end is connected to the spinning machine.

[0008] As a preferred technical solution of the present invention, two guiding rods are provided, and the two guiding rods are symmetrically distributed on both sides of the tail shaft of the spinning machine.

[0009] As a preferred technical solution of the present invention, two groups of second hydraulic cylinders are provided, and the two groups of second hydraulic cylinders are symmetrically distributed on both sides of the tail shaft of the spinning machine.

[0010] Compared with the prior art, the beneficial effects that the present invention can achieve are:

[0011] In the present invention, more than two sets of multi-executing components (such as hydraulic cylinders, air cylinders, etc.) are added to the clamping rod. A clamping die is arranged in front of the executing component, and thus the die is pressed in the reverse direction. The traditional spinning machine can only perform spinning once. After the semi-finished product, the die needs to be replaced and spun again. After adding this device, there is no need to change the machine or disassemble the product. Only after the first set of executing components push the die, spinning is carried out. After completion, the second set of executing components push the second set of dies to perform reverse spinning. The device can be formed by one-time processing of forward spinning and reverse spinning, and can be fixed during the clamping process to prevent the die from falling, saving the die cost, saving the spinning processing time, saving the die replacement time, and achieving the effect of high efficiency and energy saving.

[0014] The following is a description of the preferred embodiments of the present invention with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] The tail shaft 1 of the spinning machine is provided with a connecting support plate 9 located between the hydraulic front baffle plate 6 and the second mold mounting plate 3. The hydraulic telescopic shaft 8 is movably plugged into the connecting support plate 9, and the telescopic shaft can be limited by the connecting support plate 9 to make the operation of the telescopic shaft more stable.

[0017] A guide rod 10 is movably inserted between the hydraulic rear baffle 5, the hydraulic front baffle 6 and the connecting support plate 9. One end of the guide rod 10 is fixedly connected to one side of the second mold mounting plate 3, and the other end is connected to the spinning machine. The guide rod and the connecting support plate 9 can be used to connect and support the entire device to the spinning machine.

[0018] Two guide rods 10 are provided, and the two guide rods 10 are symmetrically distributed on both sides of the tail shaft 1 of the spinning machine, which can improve the stability of the connection.

[0019] The second hydraulic cylinders 7 are provided in two groups, and the two groups of second hydraulic cylinders 7 are evenly distributed on both sides of the tail shaft 1 of the spinning machine, which can ensure that the second mold mounting plate 3 and the second mold 4 are evenly stressed.

[0020] Specifically, when the device is used, the first hydraulic cylinder 12 is first opened to drive the tail shaft connecting plate 11 and the tail shaft 1 of the spinning machine forward, so that the first spinning process can be performed through the first mold 2; then the second hydraulic cylinder 7 is opened, and the second hydraulic cylinder 7 drives the second mold mounting plate 3 and the second mold 4 to move forward as a whole through the hydraulic telescopic shaft 8, and the product is subjected to a second reverse spinning molding.
