Description

Technical Field

[0001] This utility model relates to the field of wheel rim forming mold technology, and in particular to a wheel rim forming mold that is easy to position. Background Technology

[0002] Carbon fiber wheels are characterized by high strength, high rigidity, and light weight. In the bicycle industry, carbon fiber wheels are popular due to their lightweight properties, and in the automotive industry, they are also used because of their lightweight and high strength.

[0003] Carbon fiber wheels are typically formed by heating and pressing. During the wheel forming process, multiple ring-shaped clamps are required for fixation. These clamps are usually secured by multiple bolts. After the wheel is formed, the clamps need to be removed. Each clamp installation and removal takes a lot of time, which affects the wheel processing efficiency. Utility Model Content

[0004] This application provides a wheel rim forming mold that is easy to position, solving the problem that in the prior art, multiple annular clamps are needed to fix the wheel rim during forming. The clamps are usually fixed by multiple bolts, and the clamps need to be removed after the wheel rim is formed. Each clamp installation and removal takes a lot of time, which affects the wheel rim processing efficiency. This application enables the clamps to be removed quickly after the wheel rim is formed, reducing the time spent on clamp installation and removal and improving the processing efficiency of wheel rim forming.

[0005] This application provides a wheel rim forming mold that is easy to position, including a worktable and a forming ring, wherein the forming ring is fixed on the worktable;

[0006] It also includes a fixing component; the fixing component includes a fixing ring, a sliding groove, a rotating motor, a rotating seat, a rotating rod, and a pushing cylinder;

[0007] The bottom of the workbench is provided with multiple sliding grooves, which are distributed around the push cylinder. The rotating seat is slidably connected in the sliding grooves, and the push cylinder is fixed at the center position of the bottom of the workbench.

[0008] The rotating rod is rotatably connected to the rotating seat, and a fixing ring is fixed on the rotating rod. The fixing ring consists of four arc-shaped cast iron rings that can form a complete circular ring. The fixing ring contacts the outer wall of the wheel rim and clamps and fixes the wheel rim through the fixing ring.

[0009] The push cylinder is a multi-head cylinder, with the piston rod of the push cylinder facing the rotating seat, and the push cylinder can simultaneously drive the rotating seat to slide.

[0010] The rotating motor is located at the bottom of the workbench and fixed on the rotating seat. The rotating rod is driven to rotate by the rotating motor, which causes the fixed ring to rotate to the upper side of the workbench. This pushes the cylinder to pull the rotating seat to move in the opposite direction, so that the fixed ring clamps the wheel rim.

[0011] Furthermore, the forming ring is fixed to the base plate, and the base plate is fixed to the worktable by bolts.

[0012] Furthermore, the rotating seat is provided with a groove;

[0013] The rotating rod is rotatably connected in the groove. The rotating rod is a telescopic rod composed of multiple rectangular rods sleeved together. The telescopic rod is fixed to a specified length by screws. The length of the rotating rod can be adjusted according to the diameter of the wheel rim to be formed.

[0014] Furthermore, the portion of the rotating seat that is slidably connected within the sliding groove is I-shaped;

[0015] The sliding groove is an I-shaped groove, which is used to fix the rotating seat to the bottom of the worktable.

[0016] Furthermore, a connecting block is fixed on the rotating seat, and the fixing ring is fixed on the connecting block. The thickness of the connecting block is equal to the thickness of the worktable plus the forming ring. When the rotating rod rotates from the bottom of the worktable to the outside of the worktable, the fixing ring can be on the upper side of the forming ring, and the bottom of the fixing ring and the upper side of the forming ring are in contact.

[0017] Furthermore, the fixing ring is fixed to the connecting block by a fixing bolt;

[0018] The fixing bolt is a bolt rod, and a suitable fixing ring can be selected according to the required wheel rim diameter.

[0019] Furthermore, the connecting block has a through threaded hole, and the fixing bolt passes through the threaded hole on the connecting block and is threaded onto the rotating rod, thereby fixing the connecting block onto the rotating rod.

[0020] Furthermore, the rotating motor is a miniature servo motor.

[0021] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0022] By pushing the cylinder to drive the rotating seat to move to the end of the sliding groove away from the pushing cylinder, the rotating rod rotates to the upper side of the worktable under the drive of the rotating motor. The pushing cylinder causes the fixed ring to move towards the forming ring and form a ring on the forming ring. Through the cooperation of the forming ring and the fixed ring, the carbon fiber material is formed into a wheel rim after heating and pressurization. This solves the problem that the fixture needs to be removed after the wheel rim is formed. The installation and removal of the fixture takes a lot of time, which affects the wheel rim processing efficiency. It enables the fixture to be removed quickly after the wheel rim is formed, reducing the time spent on installing and removing the fixture. Attached Figure Description

Driven by the rotating motor 203, the rotating rod 205 rotates 180°, causing the fixed ring 201 located on the lower side of the worktable 101 to rotate to the upper side of the worktable 101. At this time, the push cylinder 208 drives the rotating seat 204 to move in the opposite direction, causing the fixed ring 201 to move towards the forming ring 103 and form a ring on the forming ring 103. Then, the material is placed in the groove on the forming ring 103.
