Description

Technical Field

[0001] This utility model relates to the field of silicone rubber component cutting technology, and more specifically, to a ring-shaped silicone rubber component cutting device. Background Technology

[0002] In the rubber products processing industry, cyclic silicone rubber parts are an important raw material or semi-finished product, widely used in various fields such as seals, shock absorbers, and medical devices. With the increasing market demand, higher requirements are being placed on the processing precision, efficiency, and quality of cyclic silicone rubber parts.

[0003] Traditional continuous rotary cutting methods struggle to ensure uniform stress distribution across the ring-shaped silicone rubber parts during the cutting process, resulting in uneven cut lines and inconsistent widths, impacting product precision and appearance. Furthermore, the instability and difficulty in precisely controlling speed variations during cutting make it challenging to achieve high-precision cutting. To address these issues, this device was invented. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a ring-shaped silicone rubber part cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ring-shaped silicone rubber part cutting device, including a worktable, a column rotatably mounted at the middle position of the top of the worktable, a rotating plate fixedly mounted on the top of the column, multiple slots equally spaced on the rotating plate, and an arc-shaped sliding groove equal in number to the slots equally spaced on the rotating plate, a receiving pad fixedly mounted on the top of the column, a vertical shaft rotatably mounted on the worktable, a contact element adapted to the arc-shaped sliding groove fixedly mounted on the top of the vertical shaft, a crossbar fixedly mounted on the vertical shaft, a locking post adapted to the slot fixedly mounted at one end of the crossbar, a driving assembly for driving the vertical shaft to rotate on the worktable, and a cutting assembly on one side of the top of the worktable.

[0006] Furthermore, the card slot has a U-shaped structure.

[0007] Furthermore, the card slot and the arc-shaped slide are alternately arranged.

[0008] Furthermore, the diameter of the arc-shaped groove is equal to the diameter of the contact element.

[0009] Furthermore, the receiving pad is made of polytetrafluoroethylene (PTFE).

[0010] Furthermore, the drive assembly includes a motor fixedly mounted on the workbench, a small gear fixedly mounted on the motor output shaft, and a large gear fixedly mounted on the vertical shaft that meshes with the small gear.

[0011] Furthermore, the cutting assembly includes a bracket fixedly mounted on one side of the top of the workbench, a frame plate fixedly mounted on the top of the bracket, a cylinder fixedly mounted on the frame plate, and a cutter connected to the end of the cylinder piston rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention achieves intermittent rotation of the rotating plate by designing slots and arc-shaped sliding grooves on the rotating plate to cooperate with the locking pins and contact parts on the vertical shaft. This ensures that the annular silicone rubber parts can rotate evenly and stably during the slitting process. Combined with the cutting assembly, it avoids the uneven cutting problem that may be caused by traditional continuous rotation, thereby improving slitting efficiency and accuracy. The method of using a motor to drive a small gear to drive a large gear reduces the rotation speed of the vertical shaft, making the entire slitting process smoother. Attached Figure Description

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.

[0022] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example:

[0024] See attached document Figures 1-4 This embodiment of a ring-shaped silicone rubber part cutting device includes a worktable 1. A column 2 is rotatably mounted at the center of the top of the worktable 1, and a rotating plate 3 is fixedly mounted on the top of the column 2, providing stable support and a rotating platform for the ring-shaped silicone rubber part, ensuring the stability and accuracy of the cutting process. Multiple slots 4 are formed at equal angles on the rotating plate 3, and the slots 4 have a U-shaped structure. The rotating plate 3 also has an equal number of arc-shaped grooves 5 formed at equal angles, with the slots 4 and arc-shaped grooves 5 alternating to ensure that the rotating plate 3 can rotate intermittently and stably, improving the cutting efficiency. To improve efficiency and precision, the number of slots 4 and arc-shaped slides 5 on the rotating plate 3 is determined according to the actual situation during use. A receiving pad 11 is fixedly installed at the top of the column 2. The receiving pad 11 has a circular cross-section and is used to receive annular silicone rubber parts. A vertical shaft 6 is also rotatably installed on the worktable 1. A contact element 7 that matches the arc-shaped slide 5 is fixedly installed at the top of the vertical shaft 6. The contact element 7 is crescent-shaped. The diameter of the arc-shaped slide 5 is equal to the diameter of the contact element 7. A crossbar 8 is fixedly installed on the vertical shaft 6. A locking post 9 that matches the slot 4 is fixedly installed at one end of the crossbar 8.

[0025] The receiving pad 11 is made of polytetrafluoroethylene (PTFE). The PTFE receiving pad 11 has good wear resistance and chemical stability, which can effectively protect the annular silicone rubber parts from scratches or contamination.

[0026] See attached document Figure 1 and Figure 2The workbench 1 is equipped with a drive assembly 10 that drives the vertical shaft 6 to rotate. The drive assembly 10 includes a motor 1001 fixedly mounted on the workbench 1. A pinion 1002 is fixedly mounted on the output shaft of the motor 1001. A large gear 1003 that meshes with the pinion 1002 is fixedly mounted on the vertical shaft 6. When in use, the motor 1001 is turned on, and the motor 1001 drives the pinion 1002 to rotate, thereby realizing the rotation of the large gear 1003 and the vertical shaft 6. Furthermore, the pinion 1002 acts as the driving element to drive the large gear 1003 and the vertical shaft 6 to rotate, which reduces the rotational speed of the vertical shaft 6 and improves the safety and stability of the operation.

[0027] When in use, the operator turns on the motor 1001, and the rotation of the vertical shaft 6 is achieved through the meshing between the small gear 1002 and the large gear 1003. The contact element 7, the crossbar 8 and the locking pin 9 rotate synchronously with the vertical shaft 6. The locking pin 9 intermittently engages in the locking groove 4, and the contact element 7 intermittently contacts the arc-shaped sliding groove 5, thereby realizing the intermittent rotation of the rotating plate 3, that is, realizing the intermittent rotation of the receiving pad 11 and the annular silicone rubber part.

[0028] See attached document Figure 1 A cutting assembly 12 is provided on one side of the top of the workbench 1. The cutting assembly 12 includes a bracket 1201 fixedly installed on one side of the top of the workbench 1. A frame plate 1202 is fixedly installed on the top of the bracket 1201. A cylinder 1203 is fixedly installed on the frame plate 1202. A cutter 1204 is connected to the end of the piston rod of the cylinder 1203. When in use, the cylinder 1203 is turned on, and the piston rod of the cylinder 1203 drives the cutter 1204 to move longitudinally, thereby realizing the cutting operation of the annular silicone rubber part.

[0029] The annular silicone rubber part cutting device drives the contact 7, crossbar 8 and locking pin 9 on the vertical shaft 6 to rotate synchronously via motor 1001. The locking pin 9 intermittently engages with the locking groove 4 on the rotating plate 3, pushing the rotating plate 3 and the annular silicone rubber part it carries to rotate intermittently. At the same time, the cylinder 1203 drives the cutter 1204 to move longitudinally, realizing the continuous cutting operation of the annular silicone rubber part.
