Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing springs, and particularly relates to a coil forming device. Background Art

[0002] The forming process of the leather bag of the shock-absorbing spring is a process of winding rubber materials and cord wires layer by layer into a cylindrical shape; the process of forming the leather bag is as follows: the material is pre-cut into the width of the semi-finished product according to the width of the finished product and the process allowance, and the length of the rolled material is preset according to the diameter of the mandrel and the thickness of the material. In order to make each layer of material completely spliced, each layer of material is cut longer, so when it is rolled into a cylindrical shape, the starting end and the ending end will overlap; the feeding direction of the material is perpendicular to the walking direction of the coiling mandrel. It is necessary for workers to manually pick up the material from the feeding and cutting place with both hands, rotate it 90° and lay it flat on the sponge table surface where the mandrel walks. When the mandrel walks, it rolls up 5 pieces of material at a time, and then the semi-finished product is taken out from the mandrel by workers.

[0003] In the existing forming process, the lap width of the material is large, and when it is made into a finished product, the larger the lap joint, the easier it is to break; at the same time, after each layer of material is rolled into a cylindrical shape, there is more or less air between the inner interlayers, which affects the service life of the leather bag; the mandrel is long and only fixed at one end, and it is easy to tilt after long-term use, and the amount of cut material will increase, and the process waste is relatively large.

[0036] Refer to Figure 6, the roll pressing and exhausting mechanism 3 includes a top plate 31, a second horizontal driving structure 32, a second vertical driving structure 33, and a roll pressing wheel 34.

In this embodiment, through holes are provided on the top plate 31, and both groups of vertical driving structures 33 penetrate through the through holes to connect the roll pressing wheel 34. Specifically, drive the second horizontal driving structure 32 to drive the second vertical driving structure 33 to be above the mandrel 222, and then drive the second vertical driving structure 33 to drive the roll pressing wheel 34 to move vertically and fit onto the coiled material on the mandrel 222 to exhaust the air inside the coiled material.

[0037] Furthermore, the second horizontal driving structure 32 is a lead screw transmission structure.

[0038] The diameter detection mechanism 4 is fixed at the bottom of the top plate 31, and the detection end is arranged towards the center direction of the mandrel 222. In this embodiment, the diameter detection mechanism 4 is a diameter detector that can be purchased in the market.

[0039] The working principle of this embodiment is as follows: Taking the rolling and pressing of 5 layers of materials as an example, the inner rubber 1, inner rubber 2, cord fabric 1, cord fabric 2, and outer rubber are cut into appropriate widths and then fed onto the feeding rack. The length of the mandrel 222 is parallel to the width of the materials.

[0040] The first step: Start. Drive the first vertical driving structure 232 to drive the first horizontal driving structure 233 to move vertically. When the center height of the mandrel support wheel 234 is the same as the center of the mandrel 221, stop the vertical movement. Then drive the first horizontal driving structure 233 to drive the mandrel support wheel 234 to move horizontally and abut against the mandrel 221.

[0041] The second step: The cutting length of the first layer of rubber material is determined according to the diameter of the mandrel 222 and is conveyed to the front end of the feeding rack. The coiling device moves according to the position of the rubber material visually detected on the feeding rack, so that the final stopping position of the movement of the mandrel 222 can match the position where the rubber material is adhered. At the same time, the forming drive motor 212 that drives the mandrel 222 to rotate stops driving. The first layer of rubber material is driven to rotate by the conveyor belt that is in close contact with the mandrel 222, and the mandrel 222 is synchronously driven to rotate together. The vacuum inside the mandrel 222 is also synchronized to wind up the first layer of rubber material.

[0042] Step 3: After the first layer of rubber material is rolled into a round shape, the vacuum inside the core rod 222 stops, and the diameter detection mechanism 4 starts to detect the thickness after rolling, thereby calculating the length of the next material to be cut, cutting in real time, and eliminating the overlapping part; when the second layer of rubber material is delivered to the front end of the feed rack, the forming mechanism 2 moves in the same way as the second step of the material rolling process. After rolling, the second horizontal drive structure 32 and the second vertical drive structure 33 are driven to drive the roller 34 to move vertically and fit on the coiled material on the core rod 222, and then move from the middle to both sides to expel the air inside the coiled material. After the air is exhausted, the roller 34 is lifted and moved to the middle, and the diameter detection mechanism 4 again detects the thickness after rolling, and then calculates the length of the next material to be cut.

[0043] Step 4: Roll the third, fourth, and fifth layers of rubber material onto the surface of the second layer of rubber material in sequence. The coil forming device moves in sequence with the servo. The process of rolling each layer is the same as that of the second layer of material.

[0044] Step 5: After the fifth layer of rubber material is rolled and exhausted, the core shaft support wheel 222 retreats to its initial position, and exhaust is exhausted from the core rod 222 through the air supply equipment box, so that the gas is discharged from the air outlet, and the product on the core rod 222 is taken out. At this point, one cycle is completed.

[0045] The coil forming device in this embodiment can move in real time according to the feeding position through the setting of the walking mechanism 1, and the material width margin is reduced or eliminated to save material; and after roller pressing and exhausting, the detected diameter data is made more accurate, the overlap is reduced or eliminated, and the service life of the product is improved; the support component 23 and the forming component 22 move and coil synchronously to ensure the stability of the core rod during use.
