Description

Technical Field

[0001] This utility model relates to the field of iron core rubber ring production technology, specifically to a rubber ring built-in iron core pressing production device. Background Technology

[0002] Common rubber rings are often used in various mechanical equipment. Because they need to be in contact with water, oil and high-pressure fluids for a long time, rubber rings will inevitably age under pressure and high temperature, and their tensile strength, elongation at break and tear resistance will be seriously reduced.

[0003] Currently, to overcome this technical problem, engineers use the method of pressing steel wires into the rubber ring to improve its durability. However, in reality, the steel wires cannot be completely encapsulated in the rubber ring in a loop, resulting in uneven material distribution in the rubber ring. This easily leads to stress concentration within the rubber ring, and the efficiency of pressing the iron core into the rubber ring is also relatively low, which cannot meet the requirements of mass production. Utility Model Content

[0004] Therefore, this utility model provides a rubber ring with built-in iron core pressing production machine to solve the problem of low output caused by the low efficiency of pressing rubber rings with built-in iron cores in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model discloses a rubber ring with built-in iron core pressing production device, comprising:

[0007] The base frame has a stepper feeder mounted on top, and a heating tray is placed on the upper end of the stepper feeder, which drives the heating tray to move horizontally.

[0008] The pressing mold is mounted on the heating tray at the bottom and has an extrusion punch on top. The extrusion punch is slidably mounted on two gantry frames, which are symmetrically arranged on both sides of the base frame.

[0009] A crank drive device is installed inside the gantry frame. The crank drive device is connected to the stepper feeder and drives the extrusion punch to move up and down in the vertical direction.

[0010] The pressing mold contains a ring-shaped iron core and rubber granules. The heating tray is used to heat the rubber granules to a molten state. After the stepper feeder moves the heating tray a certain distance, the crank drive device drives the extrusion punch to move downwards to press the molten rubber granules onto the ring-shaped iron core.

[0011] Furthermore, the pressing mold includes:

[0012] The outer shell is embedded in the heating tray. A thermal isolation wall is coaxially arranged inside the outer shell. A flow channel is provided at the bottom of the thermal isolation wall. Rubber granules are placed between the outer shell and the thermal isolation wall.

[0013] A vent pipe is located at the center of the thermal insulation wall, and trapezoidal fins are provided on the outside of the vent pipe. The trapezoidal fins are suitable for placing an annular iron core.

[0014] The rubber particles are heated and then attached to the annular iron core through the flow channel.

The front of the frame body is provided with a guide groove, which is vertically arranged and has the extrusion punch slidably arranged inside. The maintenance ladder is provided on the back side of the frame body.

[0023] Furthermore, the extrusion punch includes:

[0024] The counterweight has a pair of sliders at both ends, the sliders being adapted to slide within the guide groove, and an extrusion head at the bottom of the counterweight.

[0025] A sliding shaft is fixedly disposed at the end of the slider, and the sliding shaft is adapted to slide within the straight groove.

[0026] Furthermore, the extrusion head is annular, and an air jet hole is provided at the center of the extrusion head.

[0041] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] Please refer to this as well. Figures 1-8 This utility model discloses a rubber ring with built-in iron core pressing production device, which is used to encapsulate the iron core into rubber to form a composite rubber ring and realize mass production. The technical solution disclosed in this utility model will be described below by way of specific embodiments.

[0043] In one specific embodiment of this utility model, the rubber ring built-in iron core pressing production device includes a base frame 1, a crank transmission device 3, and pressing molds 5. A stepping feeder 2 is installed on the top of the base frame 1, which can drive a heating tray 6 to move horizontally. The heating tray 6 is located above the stepping feeder 2, and several pressing molds 5 are evenly inserted into the heating tray 6. The heating tray 6 can heat the pressing molds 5, and the pressing molds 5 contain a pre-placed annular iron core and rubber material. The heating tray 6 is suitable for heating the rubber material to a molten state. On the other hand, an extrusion punch 4 is provided above the pressing molds 5, and the extrusion punch 4 is slidably mounted on two gantry frames 7, which are symmetrically arranged on both sides of the base frame 1. When the stepping feeder 2 drives the heating tray 6 a certain distance, the extrusion punch 4 presses the molten rubber particles onto the annular iron core. The extrusion punch 4 is mainly realized through the crank transmission device 3. Specifically, the crank transmission device 3 is installed in the gantry frame 7. Since the crank transmission device 3 is connected to the stepper feeder 2, it drives the extrusion punch 4 to move up and down in the vertical direction.

[0044] In this embodiment, as Figure 7 The heating tray 6 includes an electric heating plate 61 and sleeve holes 62. The electric heating plate 61 is fixedly installed on the stepper feeder 2. A number of sleeve holes 62 are evenly arranged on the electric heating plate 61. The sleeve holes 62 are suitable for installing the pressing mold 5.

[0045] In this embodiment, as Figure 2 and Figure 5 The power unit is installed inside the base frame 1 and is connected to the crank transmission device 3 via gear or chain drive, enabling continuous operation of the equipment. The crank transmission device 3 includes a crank turntable 31 and a connecting rod 32. The back side of the crank turntable 31 is coaxially connected to a single cam 25 of the stepper feeder 2, while a fixed shaft 34 is mounted on the front side of the crank turntable 31. The fixed shaft 34 is hinged to the tail end of the connecting rod 32, and the head end of the connecting rod 32 is provided with a straight groove 33. A pressing punch 4 is slidably disposed in the straight groove 33. As the crank turntable 31 rotates, the pressing punch 4 continues to fall under the action of gravity, causing the straight groove 33 and the pressing punch 4 to slide relative to each other for a certain distance until the end of the straight groove 33 abuts against the sliding shaft 43 of the pressing punch 4. This causes the inner side and bottom end of the straight groove 33 to support the sliding shaft 43, thereby pushing the pressing punch 4 to move vertically.

[0046] Correspondingly, in some embodiments, the stepper feeder 2 includes a transfer platform 21 and a fixed base 23. The transfer platform 21 is slidably disposed on the fixed base 23. The bottom of the transfer platform 21 is provided with a sliding groove 22, and both sides of the sliding groove 22 are provided with actuating grooves 26. (Refer to...) Figure 8The fixed base 23 has several cams 25 continuously arranged on both sides, and two adjacent cams 25 are connected by a synchronous belt 24. The cams 25 are adapted to push the actuating groove 26 and drive the transfer table 21 to move intermittently in a straight line along the slide 22. During the intermittent movement of the transfer table 21, the extrusion punch 4 moves vertically to seal the annular iron core into the rubber sealing ring in the pressing mold 5.

[0047] In one specific embodiment disclosed in this utility model, such as Figure 5 The pressing mold 5 includes a shell 51, a partition wall 53, and a vent pipe 55. A heating tray 6 heats the shell 51, while a thermal partition wall 53 is coaxially arranged inside the shell 51. A flow channel 52 is provided on the thermal partition wall 53. Rubber is placed between the shell 51 and the thermal partition wall 53. The shell 51 heats the rubber to a molten state, and the extrusion punch 4 forces the molten rubber through the flow channel 52 into the thermal partition wall 53. Meanwhile, the vent pipe 55 is located at the center of the thermal partition wall 53 and is connected to a transfer table 21 with several heat dissipation holes 27 for cooling purposes. Based on this, trapezoidal fins 54 are provided on the outer side of the thermal isolation wall 53. The trapezoidal fins 54 are suitable for placing the annular iron core and are used to support the annular iron core. When the molten rubber enters the thermal isolation wall, it can immerse the annular iron core. At the same time, as the heat of the molten rubber is dissipated from the vent pipe 55, the rubber solidifies, thereby effectively encapsulating the annular iron core inside the rubber. The indentations produced by the trapezoidal fins 54 are treated by subsequent shaping.

[0048] In this embodiment, as Figure 3 The gantry frame 7 includes a frame body 71, a guide groove 72, and a maintenance ladder 73. The base frame 1 is welded and fixed to the side of the frame body 71. The guide groove 72 is provided on the front of the frame body 71. The guide groove 72 is vertically arranged and has a pressing punch 4 slidingly installed inside. The maintenance ladder 73 is provided on the back of the frame body 71. The various components of the crank transmission device 3 can be inspected by climbing the frame body 71 via the maintenance ladder 73. The crank transmission device 3 is installed inside the frame body 71, and the crank transmission device 3 drives the pressing punch 4 to move. The guide groove 72 mainly serves as an auxiliary guide.

[0049] In this embodiment, as Figure 6The extrusion punch 4 includes a counterweight 41 and a sliding shaft 43. A pair of sliders 42 are provided at both ends of the counterweight 41, and the sliders 42 are adapted to slide within the guide groove 72. An extrusion head 44 is provided at the bottom of the counterweight 41. On the other hand, a sliding shaft 43 is fixedly provided at the end of each slider 42, and the sliding shaft 43 is adapted to slide within the straight groove 33. In this embodiment, the extrusion head 44 is annular, and an air jet hole is provided at the center of the extrusion head 44. The extrusion head 44 is adapted to enter between the outer shell 51 and the thermal isolation wall 53 to extrude molten rubber, thereby allowing all the molten rubber to be squeezed into the thermal isolation wall 53 through the flow channel 52. Then, air is sprayed through the air jet hole into the vent pipe 55 to cool it down, so as to fully dissipate heat and allow the molten rubber to solidify rapidly.

[0050] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
