Description

Technical Field

[0001] The invention relates to the technical field of product processing, in particular to a necking processing device for a coil pin. Background Art

[0002] Coiled spring pins, also known as spiral pins, coil pins, disc pins, or simply spring pins, offer advantages such as excellent elasticity, balanced and even stress distribution, tighter diameter tolerances, no interlocking, seamless automatic feeding, and cost reduction. More than just a fastener, they also provide shock absorption, enhancing integrity and flexibility during assembly.

[0003] A coiled pin is made of rolled metal sheets and includes a cylindrical body with chamfered edges at each end. Prior art processes for chamfering the ends of coiled pins require manual processing, resulting in low processing efficiency and a high incidence of unqualified workmanship, impacting subsequent use. Summary of the Invention

[0004] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides a shrinkage processing equipment for a coil pin, which can automatically perform shrinkage processing on the coil, and has high processing efficiency and high shrinkage precision on each coil pin.

[0005] The technical solution of the present invention is a coil pin necking processing device, comprising a workbench, on which are provided:

[0006] Loading channel, used to transfer the coiled pins to be processed to the workbench;

[0007] The clamping member includes a fixed arm and a movable arm, wherein the movable arm is hingedly provided on the fixed arm so as to be openable or closable, and an elastic member for driving the movable arm to close is provided between the fixed arm and the movable arm;

[0008] Two necking forming parts are provided opposite to each other, and the two necking forming parts are arranged opposite to each other to form a necking forming area, and chamfered necking is provided on the opposite side of the two necking forming parts, and the interiors of the two necking forming parts are hollow;

[0009] A pressing member is provided on the side of the clamping member away from the necking forming area, and is used to drive the movable arm to open. The pressing member is provided with a guide surface for facilitating the sliding of the movable arm;

[0010] The driving member I is used to drive the clamping member to move toward the shrinking forming area to transfer the coil pin to be processed on the clamping member to the shrinking forming area;

[0011] Driving member II is used to drive the two shrinking forming parts to move toward or away from each other to perform shrinking processing on the coil pin;

[0012] The blanking channel is set below the necking forming area and is used to transfer the processed coil pins to the outside of the workbench;

[0013] The ejector pin is used to drive the processed coil pin to separate from the necking molded part. Two ejectors are provided opposite to each other and are respectively arranged in the hollow parts of the corresponding necking molded parts.

[0014] By adopting the above technical solution, the coil pins can be automatically processed for shrinking, with high processing efficiency and high processing precision. A vibration plate is installed outside the workbench, and the coil pins to be processed are arranged neatly by using the vibration plate, and are transferred one by one to the clamping member through the feeding channel. The clamping member clamps the coil pins and drives the clamping member to move toward the shrinking forming area through the driving member I, and transfers the coil pins to be processed to the forming area. The driving member II drives the two shrinking forming members to move in opposite directions, and performs shrinking processing on both ends of the coil pins on the clamping member together. After the processing is completed, the driving member I drives the clamping member to move in the direction of the shrinking forming area. The holding part returns to its position, and the driving part II drives the two shrinking forming parts to move in opposite directions, exposing the ejector pin. The processed coil pin is separated from the shrinking forming part through the ejector pin, and then automatically falls into the blanking channel. The guiding surface on the pressing part makes it convenient for the clamping part to return to its initial position and slide under the pressing part. The movable arm is opened by the pressing part to facilitate the entry of the next coil pin to be processed. The setting of the elastic part makes the movable arm automatically reset after it is separated from the pressing part, so that the movable arm is closed to clamp the coil pin to be processed to prevent it from falling during transportation.

[0015] The present invention is further configured as follows: the fixed arm is provided with a clamping groove I for installing the coil pin to be processed, and the movable arm is correspondingly provided with a clamping groove II, and a clamping area is formed between the two clamping grooves, and the clamping area corresponds to the discharge port of the loading channel.

[0016] The above-mentioned further setting makes the clamping part more stable when clamping the coiled pin to be processed, and better transfers the coiled pin to the shrinkage forming area, preventing the coiled pin to be processed from falling during the transfer process. The clamping area is set corresponding to the discharge port, so that the coiled pin to be processed can be directly put into the clamping area, saving processing time.

[0017] A further configuration of the present invention is that the workbench is further provided with a sensor for detecting whether there is a coil pin to be processed on the clamping member.

[0018] By further adopting the above-mentioned setting, it is possible to detect in real time whether there is a coil pin to be processed on the clamping part. If there is no coil pin on the clamping part, the driving part I will not work and will not drive the clamping part to move toward the necking molding area, thereby preventing the machine from doing useless work.

[0019] The present invention is further configured as follows: a fixing seat is provided on the workbench corresponding to the position of the ejector pin, and the ejector pin is fixedly arranged on the fixing seat.

[0020] By adopting the above-mentioned further arrangement, the ejector pin structure is stabilized, and the processed coil pin can be better separated from the necked molded part.

[0021] The present invention is further provided with: a mounting seat is provided on the workbench, a feeding pipe is provided on the mounting seat, and the feeding pipe is hollow to form the feeding channel.

[0022] By adopting the above-mentioned further arrangement, the structure is stable and the coiled pins to be processed can be better transported.

[0023] The present invention is further provided with a baffle I on the workbench to prevent the coil pin to be processed from falling, and the baffle I is arranged on both sides of the clamping member opposite to the mounting seat.

[0024] The above-mentioned further arrangement is adopted to prevent the coil pins to be processed from falling from the other side of the clamping member when they are transported from the feeding channel to the clamping area, thereby ensuring that each coil pin to be processed can be transferred to the processing area.

[0025] The present invention is further configured as follows: two slides are slidably provided on the workbench, the slides are connected to the output shafts of the corresponding driving members II, the two slides are slidably provided between two fixed seats, and the necking forming member is provided on the corresponding slides.

[0026] By adopting the above-mentioned further arrangement, the movement of the necking molding can be better driven, and the structure is stable.

[0027] The present invention is further provided with a baffle II on the workbench, wherein the baffle II is fixedly arranged between the two slides and is arranged opposite to the clamping member.

[0028] The above-mentioned further arrangement is adopted to prevent the processed coil pins from falling to other places when they are separated from the necking molded part, so that the processed coil pins can be better collected and time can be saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1-5 As shown, a coil pin necking processing device includes a workbench 1, on which are provided:

[0039] The loading channel 2 is used to transfer the coiled pins to be processed to the workbench 1. In order to facilitate the loading of the coiled pins, a vibration plate is set outside the workbench 1. The coiled pins to be processed are placed in the vibration plate, and the vibration plate is used to make the coiled pins enter the loading channel 2 one by one. The vibration plate is an existing technology and can be purchased on the market according to the use requirements and then used in conjunction with the processing equipment.

[0040] The clamping member 3 includes a fixed arm 31 and a movable arm 32. The movable arm 32 is hingedly provided on the fixed arm 31 so as to be openable or closable. An elastic member for driving the movable arm 32 to close is provided between the fixed arm 31 and the movable arm 32. The elastic member can be a spring or a spring.

[0041] Two necking forming parts 4 are provided opposite to each other, and the two necking forming parts 4 are provided opposite to each other to form a necking forming area, and chamfered necking 41 is provided on the opposite side of the two necking forming parts, and the interiors of the two necking forming parts 4 are hollow;

[0042] The pressing member 5 is provided on the side of the clamping member 3 away from the necking forming area, and is used to drive the movable arm 32 to open. The pressing member 5 is provided with a guide surface 51 for the movable arm 32 to slide in. The guide surface 51 is inclined.

[0043] The driving member I6 is used to drive the clamping member 3 to move toward the shrinkage forming area to transfer the coil pin to be processed on the clamping member 3 to the shrinkage forming area. The driving member I6 is set by a cylinder or an electric cylinder, which can drive the clamping member 3 to move more quickly. In order to make the structure of the clamping member 3 more stable when sliding, the workbench 1 is provided with a slide groove 10. The clamping member 3 is slidably set in the slide groove 10, and the sliding distance of the clamping member 3 can also be limited to ensure that the discharge port corresponds to the clamping area.

[0044] The driving member II7 is used to drive the two shrinking forming members 4 to move toward or away from each other to perform shrinking processing on the rolling pin. The driving member II7 is set by a cylinder or an electric cylinder, which can more quickly drive the two shrinking forming members 4 to move toward or away from each other. One or two driving members II7 can be provided. In this embodiment, two driving members II7 are provided, and one driving member II7 corresponds to each shrinking forming member 4;

[0045] The blanking channel 8 is provided below the necking forming area and is used to transfer the processed coil pins to the outside of the workbench 1;

[0046] The ejector pin 9 is used to drive the processed coil pin out of the necking molded part 4. Two ejector pins are provided opposite to each other and are respectively arranged in the hollow part 42 of the corresponding necking molded part 4.

[0047] The coil pins can be automatically processed for shrinking, with high processing efficiency and high processing precision. A vibration plate is installed outside the workbench 1, and the coil pins to be processed are arranged neatly by the vibration plate, and are transferred one by one to the clamping member 3 through the feeding channel 2. The clamping member 3 clamps the coil pins and drives the clamping member 3 to move toward the shrinking forming area through the driving member I6 to transfer the coil pins to be processed to the forming area. The driving member II7 drives the two shrinking forming members 4 to move in opposite directions, and performs shrinking processing on both ends of the coil pins on the clamping member 3 together. After the processing is completed, the driving member I6 drives the clamping member 3 to return to its original position, and the driving member I I7 drives the two shrinking forming parts 4 to move in opposite directions, exposing the ejector pin 9. The processed coil pin is separated from the shrinking forming part through the ejector pin 9, and then automatically falls into the blanking channel 8. The guide surface 51 of the pressing part 5 makes it easy for the clamping part 3 to return to the initial position and slide under the pressing part 5. The movable arm 32 is pressed by the pressing part 5 to open, so that the next coil pin to be processed can enter. The setting of the elastic part makes the movable arm 32 automatically reset after it is separated from the pressing part 5, so that the movable arm 32 closes and clamps the coil pin to be processed to prevent it from falling during transportation. The workbench 1 is also provided with a sensor for detecting whether there is a coil pin to be processed on the clamping part. It can detect whether there is a coil pin to be processed on the clamping part in real time. If there is no coil pin on the clamping part, the driving part I will not work and will not drive the clamping part to move toward the shrinking forming area to prevent the machine from doing useless work.

[0048] Specifically, the fixed arm 31 is provided with a clamping groove I311 for installing the coiled pin to be processed, and the movable arm 32 is correspondingly provided with a clamping groove II321. A clamping area is formed between the two clamping grooves. The clamping area corresponds to the discharge port of the loading channel 2, so that the clamping member 3 is more stable when clamping the coiled pin to be processed, and the coiled pin can be better transferred to the shrinkage forming area to prevent the coiled pin to be processed from falling during the transfer process. The clamping area is set corresponding to the discharge port, so that the coiled pin to be processed can be directly put into the clamping area, saving processing time.

[0049] In this embodiment, a fixing seat 11 is provided on the workbench 1 at the position corresponding to the ejector pin 9. The ejector pin 9 is fixedly mounted on the fixing seat 11, so that the ejector pin structure is stable and the processed coil pin can be better separated from the shrink molded part. The workbench 1 is provided with a mounting seat 12, and a feeding tube 121 is provided on the mounting seat 12. The feeding tube 121 is hollow and forms the feeding channel 2. The structure is stable and the coil pin to be processed can be better transported. The workbench 1 is also provided with a baffle 1 to prevent the coil pin to be processed from falling. The baffle 1 and the mounting seat 12 are arranged on both sides of the clamping member 3 opposite to each other to prevent the coil pin to be processed from falling from the other side of the clamping member 3 when it enters the clamping area from the feeding channel 2, thereby ensuring that each coil pin to be processed can be transported to the processing area. Two slides 14 are slidably mounted on the workbench 1. These slides 14 are connected to the output shafts of the corresponding drive members II7. The two slides 14 are slidably mounted between the two fixed seats 11. The necking molding member 4 is mounted on the corresponding slides 14, effectively driving the necking molding member 4 and maintaining structural stability. The workbench 1 is also provided with a baffle II15, which is fixedly mounted between the two slides 14 and positioned opposite the clamping member 3. This baffle II15 prevents the processed coil pins from falling to other locations when they detach from the necking molding member 4, allowing for better collection of the processed coil pins and saving time.
