Description

Technical Field

[0002] In the existing technology, metal fasteners made of special alloys are widely used in high-end industries. These metal fasteners are hard and can perform high-strength structural connections. They are widely used in high-tech industries such as machinery manufacturing, wind turbines, and aerospace.

[0003] In the process of processing metal fasteners, it is necessary to divide the long rod raw material made of special alloy into many small rods of equal length to form the fastener rod body. In the existing technology, the dividing process of the long rod raw material is usually achieved by cutting operation. Each small rod needs to be cut once. Due to the hard texture of special alloy, the single cutting efficiency takes a long time. In order to improve the efficiency of the metal long rod raw material dividing process, multiple cutting knives are usually set to work simultaneously to cut the long rod raw material into multiple small rods at one time. In order to ensure the stability of the cutting and dividing, the multiple cutting knives need to maintain a stable structure. This makes the distance adjustment between the multiple cutting knives not flexible and needs to rely on manual adjustment. When performing equal-length dividing processing, after the position of one cutting knife is adjusted, the positions of the other cutting knives need to be adjusted synchronously, which is cumbersome. When faced with diverse fastener rod body size requirements, this manual adjustment method cannot respond quickly, which is easy to affect the overall production efficiency.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] Example: This example provides a separating device for processing raw materials of metal fasteners, see Figure 1 - Figure 10 Specifically, it includes a machine base 1, on the left and right sides of the machine base 1, symmetrically arranged support platforms 101 are fixed, and a slide 102 is installed on the support platform 101, and an electric chuck 103 is rotated on the side close to each other on the slide 102. A cutting mechanism is provided on the back of the machine base 1, and the cutting mechanism includes a bracket 2 fixed to the machine base 1, a longitudinally arranged first slide rail 201 is fixed on the bracket 2, and a transversely arranged second slide rail 202 is fixed on the sliding end of the first slide rail 201, and a plurality of tool seats 203 are slid on the second slide rail 202, and a cutting blade 204 is fixed on the front end of each tool seat 203, and a plurality of tool seats 203 are slid on the second slide rail 202. The clamping platforms 205 on the left and right sides of the multi-tool holder 203, and the first screw 206 arranged parallel to the second slide rail 202 rotate between the left and right ends, and the first screw 206 can move through the numerous tool holders 203, and the clamping platforms 205 on the left and right sides are screwed with the first screw 206, and the thread directions of the left and right sides of the first screw 206 are opposite. A spring 207 movably sleeved on the outside of the first screw 206 is connected between the adjacent two tool holders 203, and between the tool holder 203 and the clamping platform 205. A first electric push rod 208 arranged longitudinally is fixed on the bracket 2, and the telescopic end of the first electric push rod 208 is fixedly connected to the second slide rail 202.

[0046] When the device is used, the staff uses it to cut the metal rod material, cutting the hard metal long rod material into a large number of small rods of equal length, which is convenient for the subsequent use of the small rods to process and produce high-strength metal fasteners. The device flexibly adjusts the distance between two adjacent cutting blades 204 according to the required length of the small rod. The end position of the second slide rail 202 is equipped with a servo motor for driving the first screw 206 to rotate. After the servo motor is powered on and started, it will drive the first screw 206 fixedly connected to its drive shaft to rotate. With the help of the first screw 206 The engagement with the clamping platform 205 drives the left and right clamping platforms 205 to move synchronously relative to each other. Through the synchronous movement of the left and right clamping platforms 205, the total length of the distribution of the plurality of tool seats 203 is flexibly adjusted with the middle position of the second slide rail 202 as a reference. Since the plurality of tool seats 203 are equidistantly distributed between the left and right clamping platforms 205 under the elastic support of a plurality of equal-length springs 207, the distance between the left and right clamping platforms 205 can be adjusted by adjusting the distance. Then, the distance between the two adjacent tool seats 203 can be adjusted, and then the distance between the two adjacent cutting blades 204 can be adjusted.

[0047] In this device, the clamping platform 205 at one end can also be fixedly connected to the second slide rail 202, so that the first screw 206 can be movably inserted into the clamping platform 205, and the clamping platform 205 at the other end remains slidably connected to the second slide rail 202 and is threadedly screwed to the first screw 206. Under such a structure, when adjusting the spacing of the cutting blades 204, only one clamping platform 205 will be controlled to move, and the distance between the two clamping platforms 205 will be adjusted. Although this structure will reduce the efficiency of adjusting the spacing of many cutting blades 204 to a certain extent, it will adjust many cutting blades 204 at equal distances based on one side of the fixed clamping platform 205. Compared with the structure in which the left and right clamping platforms 205 move relative to each other at the same time for adjustment, it can be suitable for different usage requirements.

[0048] During the cutting process, the long rod material to be processed is clamped between the left and right electric chucks 103. A servo motor is installed on the machine base 1 to drive the electric chucks 103 on the left and right sides to rotate synchronously, driving the long rod material to rotate at high speed and stably. Then, the many first electric push rods 208 arranged behind the bracket 2 are started, and their telescopic ends push the second slide rails 202 to drive the cutting blades 204 fixed at the front ends of the many tool holders 203 to move forward step by step. In the process of the cutting blades 204 moving forward, they gradually come into contact with the high-speed rotating long rod material. As the many cutting blades 204 gradually penetrate into the long rod material, during the high-speed rotation process, the long rod material is turned and cut into many small rods of equal length, thereby realizing deep processing of the metal long rod material. The first electric push rods 208 can be replaced with a screw mechanism as needed.

[0049] During the use of the device, the metal long rod stock is clamped between the left and right electric chucks 103 and rotated at high speed, and a plurality of cutting blades 204 are respectively fixed on a plurality of equally spaced tool holders 203, and the first electric push rod 208 is used to push the plurality of cutting blades 204 together to gradually penetrate into the long rod stock, thereby realizing the cutting and cutting operation of the long rod stock, and facilitating the one-time cutting of the long rod stock into a plurality of equal-length small rods. At the same time, the tool holder 203 is slidably installed on the second slide rail 202, and a clamping platform 205 is respectively provided on the left and right sides of the plurality of tool holders 203. By means of the threaded connection between the clamping platforms 205 on both sides and the two ends of the first screw rod 206, and the elastic support of a plurality of equal-length springs 207, the distance between two adjacent cutting blades 204 can be flexibly adjusted, and equal-length small rods of different sizes can be cut out according to actual processing requirements, thereby improving the flexibility of the device in actual use to a certain extent, and effectively improving the efficiency of the metal long rod stock cutting processing with mutual cooperation.

[0050] In the specific implementation process, Figure 4 、 Figure 6 - Figure 8 and Figure 10As shown, a self-locking mechanism is installed on the bracket 2, and the self-locking mechanism includes a limit shaft 3 rotatably installed between the left and right ends of the second slide rail 202, the limit shaft 3 is arranged parallel to the second slide rail 202, a sleeve 301 movably sleeved on the outside of the limit shaft 3 is fixed in the tool holder 203, and an elastic snap ring 302 tightly clamped on the outside of the limit shaft 3 is installed in the sleeve 301, an oil inlet joint 303 and an oil outlet joint 304 are installed on the tool holder 203, and the oil inlet joint 303 and the oil outlet joint 304 are respectively fixed to the sleeve 3 01 is connected at both ends. When the device is in use, many oil inlet joints 303 are connected to the oil pump, and many oil outlet joints 304 are connected to the oil pumping unit. The oil pump can deliver oil to the oil inlet joint 303, and the oil pumping unit can pump oil through the oil outlet joint 304. Under normal circumstances, the elastic retaining ring 302 is tightly clamped on the outside of the limit shaft 3, so that the tool holder 203 is stably connected to the limit shaft 3, avoiding the cutting blade 204 from deflecting when cutting the long metal rod, which can effectively ensure the stability of the device during operation.

[0051] After the oil is pumped into the oil pump 303, the oil in the oil pump 303 is pumped out of the oil pump 303. When the oil is pumped into the oil pump 303, the oil in the oil pump 303 is pumped out of the oil pump 303. The oil in the oil pump 303 is pumped out of the oil pump 303.

[0052] In the specific implementation process, Figure 6 and Figure 7As shown, an oil passage 305 is provided in the tool holder 203, which is connected between the oil inlet joint 303 and the oil outlet joint 304, and the oil passage 305 is wrapped around the outside of the cutting blade 204. When the device is in use, during the process of cutting and separating the long metal rod material using a plurality of cutting blades 204, the oil pump and the oil extraction unit can be started at the same time. Since the oil passage 305 is directly connected between the oil inlet joint 303 and the oil outlet joint 304, the oil will not enter the shaft sleeve 301 to squeeze and support the elastic retaining ring 302. Instead, the oil will enter the oil outlet joint 304 through the oil channel 305 and be discharged. By continuously starting the oil pump and the oil extraction unit, the oil is driven to flow continuously in the oil channel 305. Since the oil channel 305 is wrapped around the outside of the cutting blade 204, the heat generated by the cutting friction of the cutting blade 204 will be efficiently discharged outward through the flow of oil, thereby realizing the heat dissipation operation of the cutting blade 204 during the cutting and breaking process, which can effectively ensure the stability of the cutting blade 204 in the continuous cutting and breaking processing of the metal long rod.

[0053] In the specific implementation process, Figure 4 、 Figure 6 and Figure 8 As shown, an auxiliary support mechanism is fixed on the bracket 2, and the auxiliary support mechanism includes a connecting rod 4 extending to the front of the numerous cutting blades 204, and a vertically arranged stop column 401 is fixed to the front end of the connecting rod 4. A third slide rail 402 is fixed on the bracket 2 and is arranged parallel to the rear of the second slide rail 202, and a connecting platform 403 corresponding to the numerous tool seats 203 is slid on the third slide rail 402. The number of connecting rods 4 corresponds one-to-one to the numerous tool seats 203, and the numerous connecting rods 4 slide through the numerous tool seats 203 and are fixedly connected to the corresponding connecting platforms 403 respectively. A roller 404 is rotatably installed in the stop column 401, and the roller 404 is at the same height as the electric chuck 103, and the roller 404 is in front of the electric chuck 103.

[0054] When the device is in use, the metal long rod raw material is clamped between the left and right electric chucks 103 and rotated at high speed. The stop column 401 erected at the front end of the connecting rod 4 stops the front of the metal long rod, and the roller 404 rotatably installed in the stop column 401 will roll and abut against the front of the metal long rod. When the cutting blade 204 moves from the back to the front and gradually penetrates into the metal long rod for turning processing, the stop column 401 erected at the front end of the connecting rod 4 can block and support the front of the metal long rod, which can effectively ensure the stability of the cutting blade 204 when cutting and separating the metal long rod, and in the cutting and separating process, the roller 404 rolls and abuts against the metal long rod, which can avoid direct contact between the high-speed rotating metal long rod and the stop column 401, and can effectively ensure the stability of the metal long rod during high-speed rotation while ensuring the stability of the support.

[0055] When the stop column 401 is used in conjunction with the roller 404 for rolling support, the device can also provide drive for the roller 404. Many rollers 404 are in the same straight line. The same spline shaft can be slidably inserted on the central axis of the many rollers 404 and connected to a servo motor. When the metal long rod is clamped by the electric chuck 103 and rotated at high speed, the spline shaft is driven to rotate at high speed by the servo motor, driving the many rollers 404 to rotate synchronously. With the help of the rolling contact between the roller 404 and the metal long rod, the rotation of the metal long rod can be auxiliary driven, which is beneficial to further improve the stability of the metal long rod during the rotation, cutting and cutting process. The internal size of the roller 404 is adapted to the external size of the spline shaft, so that when the roller 404 slides relative to the spline shaft, it will not affect the transmission drive.

[0056] During the use of the device, numerous connecting platforms 403 are slidably installed on the third slide rail 402, and numerous connecting platforms 403 are fixedly connected to numerous connecting rods 4, so that the connecting rods 4 slide and penetrate into the tool holder 203. With the help of the longitudinal sliding connection between the connecting rods 4 and the tool holder 203, when the tool holder 203 moves in the horizontal direction, it will drive the connecting rods 4 to move synchronously in the horizontal direction. During the adjustment of the spacing between the cutting blades 204, the auxiliary support mechanism adaptively adjusts synchronously with the corresponding cutting blades 204, and always maintains a state where one cutting blade 204 corresponds to one roller 404, which improves the convenience and flexibility of the device in actual use to a certain extent.

[0057] In the specific implementation process, Figure 1 and Figure 5As shown, the slide 102 slides horizontally on the support platform 101, and the left and right slides 102 move synchronously relative to each other. A longitudinally arranged step-type bar conveying mechanism 5 is fixed in front of the machine base 1. A transversely arranged second screw 6 rotates between the left and right support platforms 101, and the left and right ends of the second screw 6 are respectively equipped with threads in opposite directions on the outer sides. The left and right slides 102 are respectively screwed with the left and right ends of the second screw 6. When the device is in use, the rear end of the step-type bar conveying mechanism 5 extends between the left and right electric chucks 103. The left and right slides 102 can move synchronously relative to each other under the drive of the second screw 6. A servo motor for driving the second screw 6 to rotate is installed on the machine base 1. With the help of the threads of the two ends of the second screw 6 engaging with the left and right slides 102, the left and right slides 102 can be driven to move away from each other synchronously, and then The step-by-step bar conveying mechanism 5 conveys the metal long rod raw material to between the left and right electric chucks 103, and the second screw 6 is driven to rotate in the opposite direction, driving the left and right slides 102 to drive the electric chucks 103 closer to each other, so that the left and right ends of the metal long rod respectively enter the left and right electric chucks 103, and then the electric chucks 103 start to close, firmly clamping the left and right ends of the metal long rod, and then the electric chucks 103 are driven to rotate for cutting and separating processing. The device can realize automatic loading operation of the metal long rod raw material and intelligent processing and conveying through the relative movement of the left and right slides 102, combined with the step-by-step conveying of the metal long rod raw material by the step-by-step bar conveying mechanism 5 and the automatic opening and closing of the electric chuck 103, which can improve the efficiency of the device in the separation processing of metal fastener long rod raw materials to a certain extent.

[0058] In the specific implementation process, Figure 5 As shown, a transmission shaft 7 is rotated through the second screw 6, and a first spline cylinder 701 arranged parallel to the transmission shaft 7 is rotated on the support platform 101, and the first spline cylinder 701 is slidably plugged into the end of the first spline cylinder 701 close to the slide 102 with a first spline shaft 702 fixedly connected to the electric chuck 103. The left and right first spline cylinders 701 are respectively connected to the left and right ends of the transmission shaft 7. When the device is used, the servo motor installed on the machine base 1 is powered on and started to drive the transmission shaft 7 to rotate. The left and right ends of the transmission shaft 7 are connected to the first spline cylinders 700 on the left and right sides through the sprocket transmission assembly. 1 transmission connection, which allows the left and right first spline cylinders 701 to rotate synchronously. The first spline shaft 702 is slidably inserted into the first spline cylinder 701. This ensures that the left and right movement and adjustment of the slide 102 will not affect the transmission of rotational power. Under the transmission connection between the transmission shaft 7, the first spline cylinder 701 and the first spline shaft 702, the left and right electric chucks 103 are driven to rotate synchronously, applying rotational power to the left and right ends of the metal long rod stock at the same time, making the force drive more balanced, and further improving the stability of the metal long rod stock during cutting and breaking.

[0059] In the specific implementation process, Figure 2 and Figure 5 As shown, a power switching mechanism is provided on the outside of the second screw 6 and the transmission shaft 7, and the power switching mechanism includes a second spline shaft 8 rotatably mounted on the left side of the machine base 1 and arranged parallel to the second screw 6, a first gear 801 is fixed to the left end of the second screw 6, and a second gear 802 of the same size as the first gear 801 is fixed to the left end of the transmission shaft 7, a second spline cylinder 803 is slidably sleeved on the second spline shaft 8, and a third gear 804 meshing with the second gear 802 is fixed on the second spline cylinder 803, a shaft seat 805 is slidably mounted on the machine base 1, the second spline cylinder 803 is rotatably connected to the shaft seat 805, a second electric push rod 806 arranged parallel to the second spline shaft 8 is fixed on the machine base 1, and the telescopic end of the second electric push rod 806 is fixedly connected to the shaft seat 805.

[0060] When the device is in use, the power switching mechanism can control the output direction of the servo motor on the machine base 1. When the servo motor is needed to rotate and drive the second screw 6, the second electric push rod 806 is powered on and started, pulling the shaft seat 805 to move, so that the third gear 804 is engaged with the first gear 801. In this state, after the servo motor is powered on and started, it will drive the second spline shaft 8 to rotate, driving the third gear 804 fixed on the second spline cylinder 803 to rotate, and with the help of the meshing of the third gear 804 and the first gear 801, the second screw 6 is driven to rotate, which is inverted to the left. The slides 102 on the right side are controlled to move relative to each other. When a servo motor is needed to rotationally drive the transmission shaft 7, the second electric push rod 806 is powered on and started to drive the third gear 804 to engage with the second gear 802. In this state, the rotational drive will be transmitted to the transmission shaft 7 to provide rotational power for the electric chucks 103 on the left and right sides. By providing a power switching mechanism, the rotational drive of the second screw 6 and the transmission shaft 7 can share a servo motor, which is beneficial to reducing the manufacturing cost of the device, and further beneficial to reducing the cost of cutting and processing long metal rod raw materials.

[0061] Specifically, the working principle and operation method of the present invention are as follows:

[0062] The third gear 804 is controlled to mesh with the first gear 801 through the power switching mechanism, driving the second screw 6 to rotate, and with the help of the threaded connection between the two ends of the second screw 6 and the slide 102, the slides 102 on both sides are driven to move away from each other synchronously, and then the metal long rod is transported to between the electric chucks 103 on the left and right sides through the stepping bar conveying mechanism 5, and the second screw 6 is driven in the reverse direction to rotate, driving the slides 102 on the left and right sides to drive the electric chucks 103 to move closer to each other, and the two ends of the metal long rod are inserted into the electric chucks 103 on both sides and clamped and fixed by the electric chucks 103, and then the third gear 804 is controlled to mesh with the second gear 802 through the power switching mechanism, driving the transmission shaft 7 to rotate, controlling the electric chucks 103 on the left and right sides to drive the metal long rod raw material to rotate at high speed, synchronously, the first electric push rod 208 is energized and started, pushing the many tool holders 203 installed on the second slide rail 202 to drive the cutting blade 204 to move forward, gradually penetrating into the high-speed rotating metal long rod, and through many cutting blades 204 cuts the long metal rod and efficiently breaks it into small rods of equal length. During the cutting and breaking process, the oil pump and the pumping unit are started synchronously to drive the oil to circulate in the oil channel 305, quickly taking away the heat generated by the cutting blade 204 during cutting and breaking, thereby improving the stability during cutting and breaking. When the spacing of the cutting blades 204 needs to be adjusted, the oil pump is started and the pumping unit is stopped. The oil is pumped into the shaft sleeve 301 through the oil inlet joint 303 and supported from the inside of the elastic retaining ring 302. , so that the elastic retaining ring 302 is separated from the limit shaft 3, and then the first screw 206 is driven to rotate, and with the help of the threaded engagement of the first screw 206 and the clamping platforms 205 on both sides, the clamping platforms 205 are driven to move, and the distance between the left and right clamping platforms 205 is adjusted. With the help of the elastic support of many equal-length springs 207, the tool holder 203 drives the cutting blades 204 to be evenly distributed between the left and right clamping platforms 205, thereby realizing the adjustment of the equal-length distance between the cutting blades 204, which is convenient for processing small metal rods of different lengths.

[0063] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
