Description

Technical Field

[0001] The present invention relates to the technical field of micro-sized semi-rigid cable space forming moulds, and more specifically to the technical field of a special mould for micro-sized semi-rigid cable space forming. Background Art

[0002] The shape curve of the semi-rigid cable should be consistent with the shape of the arc groove on the antenna feed plate (see Figure Ⅰ ) to keep them consistent, meeting the technical requirements of tight and reliable fit after assembly.

[0003] At present, the forming work of semi-rigid cable with a diameter of 1.2mm is mainly done by the processor using both hands to control the cable according to the cable embedding pattern (see Figure II ) are bent in sequence, and the deformation is repeatedly corrected to fit the shape and size of the mold.

[0004] This manual forming method is not only labor-intensive, but also requires employees to have a high level of skills and be able to accurately control many factors that affect the accuracy of the curve, such as bending angle, bending radius and bending force, etc., and the fixed-person operation mode greatly limits the improvement of production capacity. Specifically, the manual forming method has the following defects:

[0005] 1. The forming of each cable requires multiple bending and frequent manual adjustment, which results in heavy workload and extremely low production efficiency.

[0006] 2. There are many uncontrolled factors in the cable forming process. With the accumulation of shape and position errors, the product's size and shape accuracy are poor, and the workpiece yield is low.

[0007] 3. Each bend of the cable is misaligned and twisted inside the mold, posing a quality risk of tearing and abrasion of the outer skin.

[0008] 4. The physical unfolded length of the cable has a large error, and the consistency of the cable phase angle is difficult to ensure. Summary of the invention

[0009] The purpose of the present invention is to solve the above-mentioned technical problems and provide a special mold for spatially forming a micro-sized semi-rigid cable.

[0010] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0011] The invention provides a special mold for spatial forming of a miniature semi-rigid cable, comprising a base, a horizontal pressing concave-convex mold arranged on one side of the base, a spatial oblique insertion concave-convex mold arranged on the other side of the base, a horizontal push-pull type quick clamp for opening and closing the horizontal pressing concave-convex mold, and an oblique insertion push-pull type quick clamp for opening and closing the spatial oblique insertion concave-convex mold.

[0012] Specifically, the combined mold proposed in this scheme is mainly composed of four components: a horizontal pressing punch and concave mold, a spatial oblique insertion punch and concave mold, a base plate, and a push-pull quick clamp. The horizontal pressing punch and concave mold, the spatial oblique insertion punch and concave mold and the push-pull quick clamp (horizontal push-pull quick clamp or oblique insertion 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 concave-convex die and the spatial oblique insertion concave-convex die are gradually closed by the normal thrust of the push-pull type quick clamp, so that the cable is gradually extruded and formed under the constraints of the two semicircular grooves of the module.

[0014] In one embodiment, the horizontal pressing die and punch include a horizontal fixed die and a horizontal movable punch cooperating with the horizontal fixed die, the horizontal push-pull quick clamp and the horizontal movable punch horizontally reciprocate, the horizontal fixed die is provided with a first shaping semicircular groove for placing the micro-sized semi-rigid cable to be pressed, and the horizontal movable punch is provided with a second shaping semicircular groove for placing the micro-sized semi-rigid cable to be pressed, the first shaping semicircular groove and the second shaping semicircular groove have the same shape and cooperate with each other.

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

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

[0017] In one embodiment, the spatial oblique inserting concave and convex molds include an oblique inserting fixed concave mold, an oblique inserting movable convex mold cooperating with the oblique inserting fixed concave mold, the oblique inserting push-pull type quick clamp and the oblique inserting movable convex mold reciprocate horizontally, the oblique inserting fixed concave mold is provided with a third shaping semicircular groove for placing the micro-sized semi-rigid cable to be pressed, and the oblique inserting movable convex mold is provided with a fourth shaping semicircular groove for placing the micro-sized semi-rigid cable to be pressed, and the third shaping semicircular groove and the fourth shaping semicircular groove have the same shape and cooperate with each other.

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

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

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

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

[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 until it fits seamlessly with the horizontal fixed die and is locked.

[0026] Step 4: Use your hands to bend the protruding right end cable into a 90° semicircular arc groove on the first semicircular groove of the horizontal pressing concave and convex mold until it contacts the positioning slider.

[0027] Step 5. Loosen the handles of the two oblique push-pull quick clamps and the handles of the horizontal push-pull quick clamps. The horizontal fixed die and the horizontal movable punch rebound to an open state under the action of the horizontal spring. The oblique fixed die and the oblique movable punch rebound to an open state under the action of the oblique spring. Carefully take out the workpiece and the cable forming work is completed.

[0028] The beneficial effects of the present invention are as follows:

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

[0030] 2. Precision and non-destructive: The influence of human factors is reduced during the mold pressing process, and the processing accuracy is greatly improved. The cable size and shape accuracy are consistent, the bending section deformation is subtle, the cable outer skin is smooth and undamaged, and the product qualification rate is increased from 75% to more than 99.5%.
