Description

Technical Field

[0001] This utility model relates to the field of space forming mold technology for micro-sized semi-rigid cables, and more specifically to the field of a special mold technology for space forming of micro-sized semi-rigid cables. Background Technology

[0002] The outline curve of the semi-rigid cable should be consistent with the shape of the arc groove on the antenna feed plate to meet the technical requirement of tight and reliable fit after assembly.

[0003] Currently, the forming process of 1.2mm diameter semi-rigid cables is mainly carried out by the operator using both hands to bend the cable according to the groove of the cable mold, and repeatedly correcting the deformation until it fits the shape and size of the mold.

[0004] This manual forming method is not only labor-intensive but also requires employees to possess high skill levels, precisely controlling numerous factors affecting curve accuracy, such as bending angle, bending radius, and bending force. Furthermore, the fixed-person operation model significantly limits production capacity. Specifically, the manual forming method has the following drawbacks:

[0005] 1. The forming of each cable requires multiple bends and frequent adjustments by hand, resulting in a large workload and extremely low production efficiency.

[0006] 2. There are many uncontrollable factors in the cable forming process. As the shape and position errors accumulate, the size and shape and position accuracy of the product are poor, and the yield of the workpiece is low.

[0007] 3. Each bend in the cable is misaligned and twisted within the die, posing a potential quality hazard of sheath tearing and abrasion.

[0008] 4. The physical unfolded length of the cable has a large dimensional error, and it is not easy to guarantee the consistency of the cable phase angle. Utility Model Content

[0009] The purpose of this utility model is to provide a special mold for spatial forming of micro-sized semi-rigid cables in order to solve the above-mentioned technical problems.

[0010] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0011] This utility model provides a special mold for spatial forming of micro-sized semi-rigid cables, including a base, a horizontal pressing die on one side of the base, a spatial oblique insertion die on the other side of the base, a horizontal push-pull quick clamp for opening and closing the horizontal pressing die, and an oblique push-pull quick clamp for opening and closing the spatial oblique insertion die.

[0012] Specifically, the combined mold proposed in this solution mainly consists of four parts: a horizontal pressing die, a spatial oblique insertion die, a base plate, and a push-pull quick clamp. The horizontal pressing die, the spatial oblique insertion die, and the push-pull quick clamp (horizontal push-pull quick clamp or oblique push-pull quick clamp) are assembled into a whole on the base plate using screws.

[0013] Its working principle is: the movable modules of the horizontal pressing die and the spatial oblique insertion die are gradually closed by the normal thrust of the push-pull quick clamp, so that the cable is gradually squeezed and formed under the constraint of the two semi-circular grooves of the module.

[0014] In one embodiment, the horizontal pressing die includes a horizontal fixed die and a horizontal movable punch that cooperates with the horizontal fixed die. A horizontal push-pull quick clamp reciprocates horizontally with the horizontal movable punch. The horizontal fixed die is provided with a first shaped semi-circular groove for placing the micro-sized semi-rigid cable to be pressed, and the horizontal movable punch is provided with a second shaped semi-circular groove for placing the micro-sized semi-rigid cable to be pressed. The first shaped semi-circular groove and the second shaped semi-circular groove have the same shape and cooperate with each other.

[0015] In one embodiment, two horizontal guide rods are fixedly provided on the horizontal fixed die, and a horizontal movable punch is provided with horizontal guide holes through which the corresponding two horizontal guide rods pass.

[0016] In one embodiment, horizontal springs are provided on both horizontal guide rods between the horizontal fixed die and the horizontal movable punch.

[0017] In one embodiment, the spatial oblique insertion die includes an oblique insertion fixed die and an oblique insertion movable die that cooperates with the oblique insertion fixed die. The oblique insertion push-pull quick clamp and the oblique insertion movable die reciprocate horizontally. The oblique insertion fixed die is provided with a third shaped semi-circular groove for placing the micro-miniature semi-rigid cable to be pressed. The oblique insertion movable die is provided with a fourth shaped semi-circular groove for placing the micro-miniature semi-rigid cable to be pressed. The third shaped semi-circular groove and the fourth shaped semi-circular groove have the same shape and cooperate with each other.

[0018] In one embodiment, two oblique insertion guide rods are fixedly provided on the oblique insertion fixed die, and oblique insertion movable punch is provided with oblique guide holes through which the corresponding two oblique insertion guide rods pass.

[0019] In one embodiment, inclined insertion springs are provided on both horizontal guide rods between the inclined insertion fixed die and the inclined insertion movable punch.

[0020] In one embodiment, the inclined insertion push-pull quick clamp includes an inclined insertion fixed seat fixed on a base, an inclined insertion telescopic rod sliding through the top of the inclined insertion fixed seat and fixed on the inclined insertion movable punch, and an inclined insertion drive clamp that drives the inclined insertion telescopic rod to move.

[0021] In one embodiment, the horizontal push-pull quick clamp includes a horizontal fixed seat fixed to a base, a horizontal telescopic rod sliding through the top of the horizontal fixed seat and fixed to a horizontal movable punch, and a horizontal drive clamp that moves the horizontal telescopic rod.

[0022] The working principle is as follows: This solution utilizes a specialized combined mold for the entire process of tortuous deformation of a 1.2mm outer diameter micro-miniature semi-rigid cable (SWFCT-50-1-51) in space at different angles, orientations, and bending radii. It achieves fast, efficient, precise, and non-destructive forming of the cable. The working process is as follows:

[0023] Step 1: Insert a semi-rigid cable with a diameter of 1.2 mm into the middle position of the horizontal pressing die and the spatial oblique insertion die in the open state, and place it in the combined space formed by the first shaped semi-circular groove and the second shaped semi-circular groove, and place it in the combined space formed by the third shaped semi-circular groove and the fourth shaped semi-circular groove.

[0024] Step 2: Pull the handle of the inclined push-pull quick clamp to drive the inclined movable punch of the space inclined die to close and lock seamlessly with the inclined movable die; horizontal push-pull quick clamp, 5-inclined push-pull quick clamp.

[0025] The third step is to pull the handle of the horizontal push-pull quick clamp to drive the horizontal movable punch of the horizontal pressing die to close and lock it in place with the horizontal fixed die.

[0026] Step 4: By hand, bend the protruding right end cable along the 90° semi-circular groove on the first shaping semi-circular groove of the horizontal pressing die until it contacts the positioning slider.

[0027] Step 5: Loosen the handles of the two inclined push-pull quick clamps and the handle of the horizontal push-pull quick clamp. The horizontal fixed die and the horizontal movable punch will spring back to the open state under the action of the horizontal spring. The inclined fixed die and the inclined movable punch will spring back to the open state under the action of the inclined spring. Carefully remove the workpiece. The cable forming work is complete.

[0028] The beneficial effects of this utility model are as follows:

[0029] 1. Fast and efficient: The cable is formed by pressing with a mold, combining the previous three processes of straightening, forming, and straightening into one, which greatly improves processing efficiency. According to statistics, the original manual forming of cables took an average of 510 seconds per cable, while the mold forming of this application takes an average of 20 seconds per cable, improving work efficiency by 510-20 / 510≈96% or more.

[0030] 2. Precise and Non-destructive: The mold pressing process reduces the impact of human factors, significantly improving processing accuracy. The cable dimensions and positional accuracy are consistent, the bending deformation is minimal, the cable sheath is smooth and undamaged, and the product qualification rate has increased from 75% to over 99.5%.
