Description

Technical Field

[0001] The utility model relates to the technical field of connector processing equipment, specifically a 90° through-hole solder socket pin integral bending device, which is suitable for the pin bending processing of ultra-micro 90° through-hole solder sockets, realizing the overall precise bending of the socket pins, and ensuring product consistency and production efficiency. Background Art

[0002] In the production of ultra-micro connectors (90° through-hole solder sockets), the socket pin diameter is typically only 0.25mm. Machining accuracy and assembly consistency directly impact product performance. Currently, the industry typically bends these socket pins using a "sequential bending" process. The process follows: machining the socket on a mandrel machine → barrel plating → individual pin bending → assembly → pin cutting.

[0003] This processing method has obvious defects:

[0004] 1. Poor consistency: When bending a single part, the jack pins are easily deformed by external forces due to their small diameter, and the internal stress of the material after bending will cause secondary deformation of the pins. The overall position of the connector is difficult to control after assembly. Most products require additional tooling to adjust the position to meet the standards.

[0005] 2. Low efficiency: The single-step bending processing mode has cumbersome steps. It requires repeated operations to complete the bending of all the pins of a socket, which cannot meet the needs of mass production.

[0006] 3. High assembly difficulty: The pin position deviation is large after bending, and repeated calibration is required during assembly, further increasing production time and labor costs.

[0007] In response to the above problems, there is an urgent need for a special device that can achieve overall bending of socket pins, ensure processing consistency and improve efficiency. Utility Model Content

[0008] The purpose of the present utility model is to overcome the defects of poor consistency, low efficiency and difficult assembly caused by single bending of 90° through-hole solder socket pins in the prior art, and to provide a 90° through-hole solder socket pin overall bending device, which realizes precise bending and batch processing of pins through the overall bending structure design.

[0009] The above-mentioned purpose of the utility model is achieved through the following technical solutions: a 90° through-hole soldering socket pin integral bending device, comprising a first upper mounting plate, a second upper mounting plate and a lower mounting plate,

[0010] A first cylinder is fixed on the upper side of the first upper mounting plate, and an upper fixing plate is provided on the lower side. The first telescopic rod of the first cylinder is connected to the upper fixing plate, and a pressure block is fixed on the lower side of the upper fixing plate. The first upper mounting plate and the lower mounting plate are fixed by a support column, and a small guide column is provided between the first upper mounting plate and the lower mounting plate, and a first compression spring is sleeved on the small guide column.

[0011] A second cylinder is fixed on the upper side of the second upper mounting plate, a slider fixing plate is fixed on the front side, a linear guide assembly is fixed on the rear side of the slider fixing plate, and a right reinforcement plate and a left reinforcement plate are fixed on the front side; a bending head that can slide up and down is provided on the linear guide assembly, a second telescopic rod of the second cylinder is connected to the bending head, and a bending shaping end is provided at the lower end of the bending head;

[0012] The lower side of the lower mounting plate is fixed with a pad, a right support plate and a left support plate, the upper side is fixed with a right positioning block, a left positioning block, a top block, a lower bending assembly and the above-mentioned right reinforcement plate and left reinforcement plate, and the rear side is fixed with a cylinder mounting plate; a third cylinder is fixed on the cylinder mounting plate, and the third cylinder is connected to the top block through a third telescopic rod, and both sides of the top block cooperate with the right positioning block and the left positioning block;

[0013] The lower bending assembly consists of an oblique locking block, a right block, an upper block, a lower block, a left block, a first bending piece, a second bending piece, a third bending piece, and a fourth bending piece. The upper end of the lower bending assembly is provided with a complete set of shaping grooves adapted to the socket pins.

[0014] Furthermore, the bending head and the lower bending assembly are arranged in a group, and can be replaced as a whole according to the needs of sockets with different numbers of cores, and are suitable for bending processing of products of various specifications.

[0015] Furthermore, the linear guide rail assembly is provided with a dovetail groove, which plays a positioning and guiding role for the up and down sliding of the bending head, thereby ensuring the movement accuracy of the bending head during the bending process.

[0016] Furthermore, a second compression spring is provided between the top block and the lower mounting plate. When the third cylinder drives the top block to press the socket tightly, the second compression spring can provide a buffer to avoid excessive squeezing and damaging the socket housing.

[0017] The advantages of this utility model compared with the prior art are:

[0018] 1. High bending consistency: The socket pin root is positioned by the shaping groove of the lower bending component, and the overall bending action of the bending head is coordinated to achieve synchronous bending of all pins, avoiding position deviation caused by a single bend, effectively controlling the 90° bending angle accuracy and the overall position of the pin, and reducing subsequent adjustment processes;

[0019] 2. Improved production efficiency: Compared with bending one pin at a time, the overall bending method can complete the processing of all pins of the socket at one time, significantly shortening the processing time of a single product, adapting to batch production scenarios, and reducing labor costs;

[0020] 3. Strong adaptability: The bending head and the lower bending component are designed as a group, which can be quickly replaced according to the requirements of different core numbers and different bending points without the need for overall device modification, thus expanding the scope of application of the equipment;

[0021] 4. Stable and reliable operation: The right positioning block, left positioning block and top block cooperate to achieve the coarse positioning of the socket. The pressing block presses the socket shell to prevent up and down displacement. The linear guide assembly ensures the movement accuracy of the bending head. The multiple positioning and fixing structures ensure the stability of the bending process and reduce the risk of pin deformation.

[0022] 5. Reasonable structural design: The buffering effect of the compression spring, the guiding effect of the dovetail groove and other detailed designs not only protect the product from damage, but also improve the long-term stability of the device and extend the life of the equipment.

[0039] (2) Second upper mounting plate and bending assembly: The second upper mounting plate 7 is made of 45# steel plate, and the upper side is fixed with bolts to the second cylinder 9 (optional model SC40×80); the slider fixing plate 5 is made of aluminum alloy, and the rear side is fixed with bolts to the linear guide assembly 25 (including dovetail guide and slider), and the front side is welded with the right reinforcement plate 4 and the left reinforcement plate 8 (both are 45# steel plates); the bending head 23 is made of Cr12MoV mold steel, which is quenched and processed with a bent shaping end at the lower end. The upper end is connected to the slider of the linear guide assembly 25 with bolts, and is also welded to the second telescopic rod 24 of the second cylinder 9.

[0040] (3) Lower mounting plate and positioning and bending components: The lower mounting plate 2 is made of 45# steel plate, with the right support plate 1, the left support plate 13 (all angle steel) and the pad 11 (10mm thick steel plate) welded on the lower side; the right positioning block 15, the left positioning block 17 (all nylon material to avoid scratching the socket) and the lower bending component 37 are fixed on the upper side by bolts (each part is fixed by bolts, and the width of the forming groove is adapted to the diameter of the socket pin); the cylinder mounting plate 10 is an L-shaped steel plate, welded to the rear side of the lower mounting plate 2, and the third cylinder 12 (optional model SC32×30) is fixed by bolts on the upper side.

[0041] 2. The overall bending operation process of the socket pins.

[0042] Taking "bending a two-row pin socket into a four-row pin socket" as an example, the specific steps are as follows:

[0043] 1. Product loading and rough positioning:

[0044] Place the 90° through-hole welding socket to be bent into the molding groove of the lower bending component 37 so that the socket pins are completely embedded in the molding groove; start the third cylinder 12, and the third cylinder pushes the top block 16 forward through the third telescopic rod 14. The top block 16 cooperates with the right positioning block 15 and the left positioning block 17 to push the socket tightly in the bending position. At this time, the second compression spring 36 is compressed to provide buffering force.

[0045] 2. Press and fix the socket:

[0046] Start the first cylinder 22, and the first telescopic rod 26 of the first cylinder extends downward, driving the upper fixing plate 20 and the pressure block 19 to move downward along the small guide column 21 until the pressure block 19 is tightly attached to the upper surface of the socket shell, fixing the socket to prevent up and down displacement during the bending process; at this time, the first compression spring 18 is compressed to store the reset force.

[0047] 3. Overall bending forming:

[0048] Start the second cylinder 9, and the second telescopic rod 24 of the second cylinder extends downward, driving the bending head 23 to slide downward along the dovetail groove of the linear guide assembly 25; the bending shaping end at the lower end of the bending head 23 first enters the limiting groove of the lower bending assembly 37, and then continues to move downward, applying a bending force to the socket pins in the shaping groove, so that the pins complete a 90° overall bend along the shaping groove; when the limiting surface at the lower end of the bending head 23 presses against the lower mounting plate 2, the bending action is completed.

[0049] 4. Component reset and product removal:

[0050] After the bending is completed, the second cylinder 9 is controlled to exhaust, and the second telescopic rod 24 drives the bending head 23 to reset upward along the linear guide assembly 25 and separate from the lower bending assembly 37;

[0051] Then the first cylinder 22 is controlled to exhaust, and the upper fixing plate 20 and the pressing block 19 are reset upward under the rebound action of the first compression spring 18 and separated from the socket housing;

[0052] Finally, the third cylinder 12 is controlled to exhaust, and the top block 16 is reset backward under the rebound action of the second compression spring 36, releasing the tightness on the socket;

[0053] Use tweezers to gently remove the bent socket to complete the single bending operation.

[0054] 5. Specification change operation:

[0055] If you need to process sockets with different numbers of cores, just turn off the air source of the equipment, disassemble the existing bending head 23 and the lower bending assembly 37 by bolts, replace them with bending heads and lower bending assembly 37 that are adapted to the new specifications, and then re-tighten the bolts to continue production.
