Description

Technical Field

[0001] This utility model relates to the field of transmission component manufacturing technology, specifically to a near-net-shape forming equipment for transmission components. Background Technology

[0002] Transmission components are essential parts of mechanical systems, primarily designed to transmit power and motion. They achieve the transmission of power and motion within mechanical equipment through various transmission methods, such as mechanical transmission, fluid transmission, and electric transmission. The main types of transmission components include shafts, keys, bearings, couplings, and clutches.

[0003] For gears, die casting is usually used in the production process. In the near-net-shape forming process of gears, the metal material usually needs to be heated and melted, and then introduced into the forming equipment for cooling. After cooling, it is then die-cast. Due to the different heating and melting times, the metal material introduced into the forming equipment may not be completely melted, which can easily affect the subsequent forming quality.

[0004] Therefore, it is necessary to design a near-net-shape forming equipment for transmission components to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a near-net-shape forming equipment for transmission components to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A near-net-shape forming equipment for transmission components includes a base body. Support columns are fixedly installed at the four corners of the top of the base body. A connecting plate is fixedly installed on the top of the support columns. A top frame is fixedly connected to the top of the connecting plate through the support columns. A drive cylinder is fixedly installed on the top of the connecting plate. A forming cylinder is fixedly installed at the bottom of the connecting plate. A bearing platform is fixedly installed at the bottom of the forming cylinder. A metal material injection pipe is provided on one side of the forming cylinder. A hot and cold integrated machine is connected to the other side of the forming cylinder through a hot and cold pipe.

[0008] As a preferred embodiment of this utility model, a mold head is provided inside the forming cylinder, a cooling and heating layer is provided between the forming cylinder and the mold head, and a forming mold is provided at the bottom of the forming cylinder. The mold head and the forming mold are used in cooperation with each other.

[0009] As a preferred embodiment of this utility model, the top of the support platform is provided with multiple support rods, and the tops of the multiple support rods and the bottom of the connecting plate are fixedly connected by bolts.

[0010] As a preferred embodiment of this utility model, the inner wall of the molding cylinder is provided with a plurality of guide blocks, and the outer surface of the die head is provided with a guide groove, wherein the guide blocks and the guide groove are slidably connected.

[0011] As a preferred embodiment of this utility model, the molding cylinder is provided with a connection interface that extends into the internal cavity of the cooling and heating layer. One side of the cooling and heating pipe is threadedly connected to the connection interface, and the other side of the cooling and heating pipe is threadedly connected to the output interface of the integrated cooling and heating machine.

[0012] As a preferred embodiment of this utility model, the metal material injection pipe is a heat-resistant pipe, and a one-way valve body is provided between it and the forming cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a near-net-shape forming equipment for transmission components is provided. Since the near-net-shape forming equipment is connected to a heating and cooling integrated machine, a heating and cooling pipe, and a heating and cooling layer, the heating and cooling integrated machine can generate hot or cold air.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0025] A near-net-shape forming equipment for transmission components includes a base body 1. Support columns 2 are fixedly installed at the four corners of the top of the base body 1. A connecting plate 3 is fixedly installed on the top of the support columns 2. A top frame 4 is fixedly connected to the top of the connecting plate 3 via the support columns 2. A drive cylinder 5 is fixedly installed on the top of the connecting plate 3. A forming cylinder 6 is fixedly installed at the bottom of the connecting plate 3. A bearing platform 7 is fixedly installed at the bottom of the forming cylinder 6. A metal material injection pipe 8 is provided on one side of the forming cylinder 6. A hot and cold integrated machine 10 is connected to the other side of the forming cylinder 6 via a hot and cold pipe 9.

[0026] Specifically, a mold head 61 is provided inside the molding cylinder 6. The top of the mold head 61 is fixedly connected to the bottom output end of the drive cylinder 5. A cooling and heating layer 62 is provided between the molding cylinder 6 and the mold head 61. A molding mold 63 is provided at the bottom of the molding cylinder 6. The mold head 61 and the molding mold 63 cooperate with each other. Multiple support rods 11 are provided on the top of the support platform 7. The top of the multiple support rods 11 is fixedly connected to the bottom of the connecting plate 3 by bolts. Multiple guide blocks 64 are provided on the inner wall of the molding cylinder 6. A guide groove 65 is opened on the outer surface of the mold head 61. The guide blocks 64 and the guide groove 65 are slidably connected.

[0027] In this embodiment, the lower die head 61 is driven downward by the drive cylinder 5, and the guide block 64 moves downward synchronously in the guide groove 65. This causes the die head 61 to press the molten and cooled metal material in the forming mold 63 located inside the forming cylinder 6, thereby achieving near-net-shape forming. Under the guidance of the guide block 64 and the guide groove 65, the vertical displacement of the die head 61 and the forming mold 63 can be avoided, thus improving the quality of near-net-shape forming.

[0028] The metal material injection pipe 8 is connected to the injection system of the equipment, which mainly consists of an injection cylinder, an injection piston, an injection head, and a nozzle. The metal material injection pipe 8 is a heat-resistant pipe, and a one-way valve 12 is installed between it and the molding cylinder 6. The metal material is first heated to a molten state, and then pushed into the injection cylinder by the injection piston. Then, under high pressure, the molten metal is injected into the molding mold 63 through the nozzle, quickly filling the mold cavity. The one-way valve 12 prevents the metal material from flowing back from the metal material injection pipe 8.

[0029] Specifically, the molding cylinder 6 is provided with a connection interface that extends into the internal cavity of the cooling and heating layer 62. One side of the cooling and heating pipe 9 is threadedly connected to the connection interface, and the other side of the cooling and heating pipe 9 is threadedly connected to the output interface on the integrated cooling and heating machine 10.

[0030] In this embodiment, hot or cold air can be generated by the integrated heating and cooling machine 10 as needed. The hot or cold air is introduced into the cooling and heating layer 62 inside the molding cylinder 6 through the heating and cooling pipe 9, so as to reheat and melt or cool the metal material located in the molding mold 63, thereby improving the efficiency of subsequent near-net-shape molding.

[0031] The working process of this utility model is as follows: When using the near-net-shape forming equipment with this transmission component, the pre-molten metal material is introduced into the forming mold 63 located inside the forming cylinder 6 through the metal material injection pipe 8 via the injection system. After the introduction is completed, the one-way valve 12 is opened to prevent further introduction of metal material. Then, the integrated heating and cooling machine 10 is started. First, the heating mode is activated, and hot air is introduced into the heating and cooling layer 62 through the heating and cooling pipe 9 to heat the metal material in the forming mold 63 inside the forming cylinder 6, so that the metal material is completely melted. Then, the driving cylinder 5 drives the lower die head 61 to move downward, while simultaneously... The guide block 64 moves synchronously downwards in the guide groove 65, thereby causing the die head 61 to press the molten and cooled metal material in the forming mold 63 located below the inside of the forming cylinder 6, so as to achieve near-net-shape forming operation. Under the guidance of the guide block 64 and the guide groove 65, the die head 61 and the forming mold 63 can be prevented from shifting in the vertical direction, thus improving the quality of near-net-shape forming. After the die casting is completed, the integrated cooling and heating machine 10 is adjusted to the cooling mode, and the cold air is introduced into the cooling and heating layer 62 through the cooling and heating pipe 9. After a period of time, the transmission components in the forming mold 63 inside the forming cylinder 6 are rapidly cooled, thus improving the near-net-shape forming efficiency of the transmission components.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
