Description

Technical Field

[0001] This utility model relates to the field of digital tube processing technology, and in particular to a tooling for bending the pins of digital tubes. Background Technology

[0002] In the field of digital tube manufacturing, the existing technology requires the processing of PIN pins for digital tubes with three bending angles to be completed in two stages: the first stage is completed by an operator using a double bending machine to complete the first two bends; the second stage is completed by a single bending machine and another operator to complete the third bend. This results in low processing efficiency and waste of human resources. Even if a three-bending mold exists in the existing technology, some products will have a shortage of PIN pins when the three-bending mold is formed in one go, which affects the product qualification rate. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0004] Therefore, one objective of this utility model is to provide a digital tube PIN bending tool to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, this utility model provides a digital tube PIN bending fixture, comprising: a base with a sliding groove thereon; a lower cutter assembly disposed in the sliding groove and capable of sliding along the sliding groove; and an upper cutter disposed above the lower cutter assembly, the upper cutter having a fixing groove, and a first folding surface and a first inclined surface below the fixing groove.

[0006] The cutting assembly includes: a fixed block; a first folding blade, one end of which is connected to the fixed block via an elastic component; and a second folding surface at the other end of the first folding blade, which cooperates with the first folding surface.

[0007] The second folding blade has one end connected to the fixed block; the other end of the second folding blade is provided with a second bevel.

[0008] The second inclined plane mates with the first inclined plane.

[0009] The bottom surface of the first folding blade mates with the top surface of the second folding blade. When the elastic component is in its natural state, the distance from the second folding surface to the fixed block is greater than the distance from the second inclined surface to the fixed block.

[0010] Preferably, the elastic component includes a spring and a limiting post. The bottom surface of the first folding blade is provided with a first semi-circular groove, and the top surface of the second folding blade is provided with a second semi-circular groove. The first semi-circular groove and the second semi-circular groove cooperate to form a circular groove. One end of the spring abuts against the bottom of the circular groove, and the other end of the spring abuts against the fixing block. The limiting post passes through the fixing block and is connected to one end of the first folding blade. The limiting post can slide relative to the fixing block along the axial direction of the limiting post.

[0011] In any of the above solutions, it is preferred that there are two spring assemblies.

[0012] In any of the above solutions, it is preferred that a pin groove is provided at the bottom of the fixing groove.

[0013] In any of the above embodiments, the first fold surface preferably includes:

[0014] The first extension section and the first bending section are: the first extension section extends from the bottom end of the pin groove in a direction away from the lower cutting assembly and forms a first angle with the bottom of the upper cutting assembly; the first bending section bends from the end of the first extension section in a direction closer to the lower cutting assembly to form a predetermined angle.

[0015] In any of the above embodiments, it is preferred that the first inclined surface extends from the end of the first bent section in a direction away from the cutting assembly, and the first inclined surface is arranged parallel to the first extension section.

[0016] In any of the above embodiments, the second folded surface preferably includes:

[0017] The second extension section extends from the top of the first folding blade toward the direction close to the first folding surface; the second bending section bends from the end of the second extension section toward the direction away from the first folding surface to form a predetermined angle.

[0018] In any of the above embodiments, it is preferred that the second inclined surface extends from the top of the second folding blade toward the direction close to the first folding surface, and the second inclined surface is arranged parallel to the second extension segment.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0020] This invention utilizes the synergistic action of the first and second folding facet groups to achieve two precise bends on the PIN pin. A third fold is then achieved through the guiding cooperation of the first and second inclined planes, forming a three-stage progressive bending process that significantly improves processing efficiency. The first folding blade preferentially contacts the first folding facet group to complete the initial bend, while the second folding blade intervenes after a delay, cooperating with the first inclined plane to perform a secondary bend. This time-sharing action design effectively disperses bending stress, solves the PIN pin breakage problem, and significantly improves product yield.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figures 1 to 7 As shown, a digital tube PIN bending fixture according to an embodiment of the present invention includes: a base 1 with a sliding groove 2 thereon; a lower cutter assembly disposed within the sliding groove 2 and capable of sliding along the sliding groove 2; and an upper cutter 3 disposed above the lower cutter assembly, the upper cutter 3 having a fixing groove 4, and a first folded surface and a first inclined surface 5 below the fixing groove 4.

[0034] The cutting assembly includes: a fixed block 6, a first folding blade 7, one end of which is connected to the fixed block 6 via an elastic component; the other end of the first folding blade 7 has a second folding surface that mates with the first folding surface. A second folding blade 8, one end of which is connected to the fixed block 6; the other end of the second folding blade 8 has a second inclined surface 16 that mates with the first inclined surface 5. The bottom surface of the first folding blade 7 mates with the top surface of the second folding blade 8. When the elastic component is in its natural state, the distance from the second folding surface to the fixed block 6 is greater than the distance from the second inclined surface 16 to the fixed block 6.

[0035] The fixing slot 4 is used to fix the digital tube. One end of the fixing slot 4 is provided with multiple pin slots 11, which are used to fix the PIN pins on the digital tube. The blade holder is a C-shaped mechanism. The lower blade assembly is placed in the slide groove 2 inside the blade holder and can move in the slide groove 2. The upper blade 3 is fixed to the blade holder by M4 bolts. Through the cooperation of the upper blade 3 and the lower blade assembly, the PIN pins of the digital tube can be folded at three angles at one time.

[0036] The lower blade can reciprocate within the blade holder, with a travel distance of 2-4cm. The upper blade 3 is fixed to the surface of the blade holder by four M4 bolts. The lower blade assembly consists of two parts, an upper and a lower blade, including a first folding blade 7 and a second folding blade 8. The sequential movement of the first folding blade 7 and the second folding blade 8 is controlled by a spring assembly 9 to complete the operation. The hardness of the upper blade 3, the first folding blade 7, and the second folding blade 8 is HRC60-62HRC. The sequential movement of the first folding blade 7 and the second folding blade 8 completely avoids the PIN pins from easily breaking when bending.

[0037] Furthermore, the elastic component includes a spring 9 and a limiting post 10. The bottom surface of the first folding blade 7 has a first semi-circular groove, and the top surface of the second folding blade 8 has a second semi-circular groove. The first and second semi-circular grooves cooperate to form a circular groove. One end of the spring 9 abuts against the bottom of the circular groove, and the other end abuts against the fixing block 6. The limiting post 10 passes through the fixing block 6 and is connected to one end of the first folding blade 7. The limiting post 10 can slide relative to the fixing block 6 along its axial direction. The other end of the limiting post 10 is provided with a nut or screw head. The limiting post 10 can slide relative to the fixing block 6 along its axial direction. When the first folding blade 7 translates relative to the second folding blade 8, it can compress the spring 9.

[0038] As another embodiment, a complete circular groove can be directly opened on the first folding blade 7 to accommodate the spring 9.

[0039] The bottom surface of the first folding blade 7 is in contact with the top surface of the second folding blade 8, and the first folding blade 7 can slide on the top surface of the second folding blade 8.

[0040] Specifically, there are two spring 9 assemblies. There are two spring 9 assemblies and two limiting posts 10 assemblies. One end of the first folding blade 7 is provided with two circular grooves, and one spring 9 is provided in each circular groove. One end of the limiting post 10 passes through the fixing block 6 and is connected to one end of the first folding blade 7. The limiting post 10 is used to prevent the first folding blade 7 from disengaging from the fixing block 6.

[0041] The bottom end of the fixing groove 4 is provided with a pin groove 11, which includes a plurality of parallel grooves for fixing PIN pins. The grooves are inclined, and as an optional embodiment, the pin groove 11 has an angle of 30 degrees with the horizontal plane.

[0042] Specifically, the first fold includes: a first extension segment 12, the bottom end of the needle corner groove extends away from the lower blade assembly and forms a first angle with the bottom of the upper blade 3; and a first bending segment 13, which bends from the end of the first extension segment 12 toward the lower blade assembly to form a predetermined angle.

[0043] The first extension segment 12 is an inclined plane. In a preferred embodiment, the first extension segment makes an angle of 60 degrees with the horizontal plane. The first bending segment 13 is an inclined plane. Optionally, the angle between the first bending segment 13 and the first extension segment 12 is 90 degrees. The angle between the first inclined plane 5 and the first bending segment 13 is 90 degrees. One end of the first bending segment 13 is connected to the first extension segment 12, and the other end of the first bending segment 13 is connected to the first inclined plane 5.

[0044] Specifically, the first inclined surface 5 extends from the end of the first bent section 13 in a direction away from the cutting assembly, and the first inclined surface 5 is arranged parallel to the first extension section 12.

[0045] Furthermore, the second fold includes:

[0046] The second extension 14 extends from the top of the first folding blade 7 towards the direction close to the first folding surface; and

[0047] The second bending segment 15 bends from the end of the second extension segment 14 away from the first bending surface to form a predetermined angle.

[0048] The second inclined surface 16 extends from the top of the second folding blade 8 towards the direction close to the first folding surface, and the second inclined surface 16 is arranged parallel to the second extension section 14. The second folding blade 8 cooperates with the slide groove 2, and the second folding blade 8 slides on the slide groove 2, driving the first folding blade 7 to move.

[0049] Both the second extension section and the second bending section are inclined planes. The second extension section is parallel to the first extension section, and the second bending section is parallel to the first bending section. The second inclined plane is parallel to the first inclined plane. The angle between the second extension section and the second bending section is 90 degrees. In its natural state, the distance from the first folding blade to the first folding surface is greater than the distance from the second folding blade to the first folding surface. During operation, the second folding blade moves along the slide, causing the first folding blade to move closer to the first folding surface. The first folding blade first cooperates with the first folding surface to complete two bends on the PIN pin. The first bend of the PIN pin is at the bottom of the pin groove. The first folding blade first applies force to the PIN pin, causing the PIN pin to bend at the bottom of the pin groove. The second bend occurs at the intersection of the first extension section and the second bending section. The PIN pin is bent between the first and second bends. As the first bend continues to apply force, the PIN pin is bent between the first extension and the first bend. At this time, the first bend presses the PIN pin completely onto the first bend surface. As the second bend continues to move, it drives the fixing block to compress the spring connected to the first bend. The second bend moves relative to the first bend and presses the end part of the PIN pin onto the first bend through the second slope. The PIN pin is bent between the first bend and the first slope. The second bend completes the third bend of the PIN pin.

[0050] The working principle of this utility model of digital tube PIN bending fixture is as follows: The digital tube is installed in a fixed groove, and the PIN pins on the digital tube are fixed in the pin groove. The excess part of the PIN pin extends into the bottom of the pin groove. The second folding surface on the first folding blade first contacts the first folding surface, and performs two precise bending processes on the PIN pin. Then, the second folding blade continues to move along the slide, compressing the spring. The second inclined surface on the second folding blade cooperates with the first inclined surface to complete the third bending of the PIN pin. Three bending angles of the PIN pin can be achieved in one operation, which improves efficiency and saves costs.
