Description

Technical Field

[0001] This invention relates to the field of piston pin heat treatment, and more specifically, to an intelligent piston pin heat treatment production line and its process control technology. Background Technology

[0002] The intelligent heat treatment production line for piston pins is a specialized production line that utilizes automation, digitalization, and intelligent technologies to realize the heat treatment process for piston pins. Its core function is to steadily improve the hardness, wear resistance, fatigue strength, and dimensional accuracy of piston pins.

[0003] For example, the specification of the Chinese utility model patent (application number: 202020917925.3) "A heat treatment device for piston pin production" discloses that: it includes a furnace body, a rotating box rotatably connected to the bottom of the furnace body cavity, a worm gear provided on one side of the rotating box, a worm wheel meshing with the outer side of the worm gear, a threaded rod fixedly connected to the axis of the worm wheel, a threaded block threadedly connected to the outer side of the threaded rod, a slide rod fixedly connected to the top of the threaded block, a through groove for cooperating with the slide rod on the top of the rotating box, a sliding connection between the outer side of the slide rod and the inner wall of the through groove, a clamping plate fixedly connected to one side of the top of the slide rod, and two slide rods and two clamping plates symmetrically set.

[0004] However, the aforementioned heat treatment equipment for piston pin production has some shortcomings in actual use: In the prior art, by driving the clamping plate to slide and clamping and fixing the piston pin, the clamping end of the clamping plate will block the piston pin. When the piston pin is heat treated, the area of ​​the piston pin blocked by the clamping plate cannot directly receive the heat source, which makes the area heat up slowly, resulting in poor surface hardness uniformity of the piston pin and a low piston pin qualification rate.

[0005] Therefore, we have made improvements to this and proposed an intelligent heat treatment production line for piston pins and its process control technology. Summary of the Invention

[0006] The purpose of this invention is to address the problem that, during the heat treatment of piston pins, the area blocked by the clamping plate cannot directly receive the heat source, resulting in a low pass rate for piston pin heat treatment.

[0017] As a preferred technical solution of this application, the electric telescopic rod is provided with an adjusting shaft, the connecting block is rotatably mounted on the adjusting shaft, and the furnace body is provided with a discharge plate.

[0018] As a preferred technical solution of this application, the connecting block and the discharge plate are adapted to each other, and the adjusting shaft and the connecting block are connected by a torsion spring.

[0019] The process control method for the intelligent heat treatment production line of piston pins is as follows:

[0020] Step S1: Place the piston pin into the feed inlet. The piston pin enters the feed inlet and is pressed and fixed by the extrusion rollers. The elasticity of the spring drives the extrusion rollers to press the piston pin, so that the piston pin is fixed at the center of the four extrusion rollers. Start the motor. The motor output drives the transmission shaft and transmission gear to rotate synchronously. The transmission gear drives the transmission gear ring to rotate. The transmission gear ring and drive gear ring rotate synchronously. The drive gear ring drives the drive gear to rotate. The drive gear rotates and drives the drive shaft to rotate synchronously. The drive shaft drives the rectangular block and the extrusion rollers to rotate synchronously. The piston pin rotates and drives the piston pin to rotate. The piston pin rotates and cooperates with the furnace body. The furnace body heats the piston pin, so that the piston pin is heated evenly. The piston pin and the extrusion rollers are always in a sliding state due to the rotation of the extrusion rollers.

[0021] Step S2: Start the electric telescopic rod one. The electric telescopic rod one drives the adjusting rod to slide upward. The adjusting rod drives the sliding ring to slide upward along the adjusting groove. The wedge block three on the sliding ring is adapted to wedge block one. When the motor drives the transmission shaft to rotate, the transmission shaft drives the adjusting groove to squeeze the sliding ring, so that the sliding ring rotates synchronously. The wedge block three on the sliding ring squeezes the wedge block one, so that the wedge block one and the synchronous gear rotate synchronously. At this time, the synchronous gear drives the synchronous gear ring to rotate. The arc groove on the synchronous gear ring rotates synchronously. The arc groove rotates and squeezes the top column, so that the top column slides along the strip groove. The top column slides and squeezes the annular groove, so that the extrusion roller slides synchronously with the top column. At this time, the rectangular block slides along the sliding groove, the spring is compressed, the extrusion roller unfolds and releases the limit on the piston pin. Start the electric telescopic rod two. The electric telescopic rod two drives the connecting block to slide. The connecting block drives the support column to slide synchronously. The piston pin is pushed by the support column. The position of the piston pin in the furnace body is adjusted by the sliding of the support column, so that the piston pin is at the optimal temperature during heat treatment.

[0022] Step S3: Start the electric telescopic rod two. The electric telescopic rod two drives the connecting block to slide and unfold and squeeze the discharge plate. The discharge plate squeezes the connecting block and makes it rotate. The connecting block rotates and makes the support column rotate synchronously. The piston pin on the support column rotates and makes the piston pin automatically discharge material.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] In the scheme of this application:

[0025] 1. In order to solve the problem that the area blocked by the clamping plate cannot directly receive the heat source during the heat treatment of piston pins in the prior art, resulting in a low pass rate of piston pin heat treatment, this application sets up a synchronous adjustment mechanism. The synchronous adjustment mechanism drives the contact end of the piston pin and the extrusion roller to always be in a sliding state, so that the piston pin is heated evenly. This method avoids the situation of the existing clamping mechanism blocking the piston pin and improves the pass rate of piston pin heat treatment.

[0026] 2. By using a synchronized adjustment mechanism, the piston is flexibly clamped and the pressure is evenly distributed, avoiding the deformation of the piston pin during heat treatment caused by the existing rigid extrusion, thus improving the quality of the piston pin after heat treatment and solving the problem of easy deformation caused by rigid clamping in the prior art.

[0027] 3. By setting a synchronous adjustment mechanism, the position of the piston pin in the furnace body is adjusted so that the piston pin is at the optimal temperature during heat treatment, reducing the energy consumption of the furnace body and improving the heat treatment efficiency of the piston pin, thus solving the problem of low efficiency caused by fixed-position heat treatment in the prior art.

[0028] 4. By setting up a synchronous adjustment mechanism, the piston pin is automatically discharged, reducing the number of steps for workers to discharge materials, improving work efficiency, and solving the problem of low efficiency in material discharge work by existing technical workers.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0041] As described in the background art, when piston pins undergo heat treatment, the area shielded by the clamping plate cannot directly receive the heat source, resulting in a low pass rate for piston pin heat treatment.

[0042] To address this technical problem, the present invention provides an intelligent heat treatment production line for piston pins and its process control technology, which is applied to the heat treatment of piston pins.

[0043] For details, please refer to Figure 1 - Figure 8 As shown, the intelligent heat treatment production line for piston pins specifically includes: a furnace body 1, including a synchronous adjustment mechanism 2 installed on the furnace body 1;

[0044] The synchronous adjustment mechanism 2 includes a drive shaft 201 rotatably disposed inside the furnace body 1, a feed inlet 202 disposed on the furnace body 1, a rectangular block 203 disposed on the drive shaft 201, a pressing roller 204 disposed on the rectangular block 203, a sliding groove 205 disposed on the pressing roller 204, a spring 206 disposed on the sliding groove 205, a drive gear 207 disposed on the drive shaft 201, a drive gear ring 208 rotatably disposed on the furnace body 1, a transmission shaft 209 rotatably disposed on the furnace body 1, a motor 210 disposed on the furnace body 1, a transmission gear 211 disposed on the transmission shaft 209, and a transmission gear ring 212 disposed on the drive gear ring 208.

[0045] The intelligent heat treatment production line for piston pins and its process control technology provided by this invention address the problem in the prior art where the area blocked by the clamping plate cannot directly receive the heat source during piston pin heat treatment, resulting in a low pass rate for piston pin heat treatment. This application uses a synchronous adjustment mechanism 2 to drive the contact end between the piston pin and the extrusion roller 204 to always be in a sliding state, so that the piston pin is heated evenly. This method avoids the situation where the existing clamping mechanism blocks the piston pin, thereby improving the pass rate of piston pin heat treatment.

[0046] By using the synchronous adjustment mechanism 2, the piston is flexibly clamped and the pressure is evenly distributed, avoiding the deformation of the piston pin during heat treatment caused by the existing rigid extrusion, thus improving the quality of the piston pin after heat treatment and solving the problem of easy deformation of rigid clamping in the prior art.

[0047] By setting the synchronous adjustment mechanism 2, the position of the piston pin in the furnace body 1 is adjusted so that the piston pin is at the optimal temperature during heat treatment, thereby reducing the energy consumption of the furnace body 1 and improving the heat treatment efficiency of the piston pin. This solves the problem of low efficiency caused by fixed-position heat treatment in the prior art.

[0048] By setting up a synchronous adjustment mechanism 2, the piston pin is automatically discharged, reducing the number of steps for workers to discharge materials, improving work efficiency, and solving the problem of low efficiency in material discharge work by existing technology workers.

[0049] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0050] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0051] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0052] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a piston pin intelligent heat treatment production line has a rectangular block 203 slidably disposed on a sliding groove 205, two ends of a spring 206 respectively disposed on the corresponding surfaces of the sliding groove 205 and the rectangular block 203, a drive gear 207 and a drive gear ring 208 adapted to each other, a transmission shaft 209 disposed on a motor 210, and a transmission gear 211 and a transmission gear ring 212 adapted to each other.

[0053] In use, the piston pin is placed into the feed inlet 202. The piston pin enters the feed inlet 202 and is then pressed and fixed by the extrusion rollers 204. Four extrusion rollers 204 are provided. Figure 2 As shown, the spring 206 elastically drives the extrusion roller 204 to press the piston pin, fixing the piston pin at the center of the four extrusion rollers 204. The initial positions of the drive shaft 201 and the rectangular block 203 are eccentric positions of the extrusion rollers 204. When the piston pin is at the center of the four extrusion rollers 204, it presses the extrusion roller 204, causing it to shift. This positions the drive shaft 201 and the rectangular block 203 at the center of the extrusion roller 204. At this time, the motor 210 is started. The output of the motor 210 drives the transmission shaft 209 and the transmission gear 211 to rotate synchronously. The transmission gear 211 drives the transmission gear ring 212 to rotate. The transmission gear ring 212 and the drive gear ring 208 rotate synchronously. The drive gear ring 208 drives the drive gear 207 to rotate. The drive gear 207 rotates and drives the drive shaft 201 to rotate synchronously. 01 drives the rectangular block 203 and the extrusion roller 204 to rotate synchronously. The rotation of the four extrusion rollers 204 drives the piston pin to rotate. The piston pin rotates and cooperates with the furnace body 1. The furnace body 1 heats the piston pin, making the piston pin heated evenly. The rotation of the extrusion rollers 204 keeps the contact end between the piston pin and the extrusion rollers 204 in a sliding state, avoiding the piston pin clamping end from being in a stationary state. This method avoids the situation where the existing clamping mechanism blocks the piston pin, improving the pass rate of piston pin heat treatment. The elasticity of the spring 206 drives the extrusion rollers 204 to clamp the piston pin. Compared with the existing technology, the extrusion rollers 204 slide and extrude along the surface of the piston pin. The flexible clamping makes the pressure distribution uniform, avoiding the deformation of the piston pin during heat treatment caused by the existing rigid extrusion.

[0054] Furthermore, an annular groove 213 is provided on the extrusion roller 204, and a top moving column 214 is slidably provided on the annular groove 213. A fixing plate 215 is provided inside the furnace body 1, and a strip groove 216 is provided on the fixing plate 215. A synchronous gear ring 217 is rotatably provided on the fixing plate 215, and an arc groove 218 is provided on the synchronous gear ring 217.

[0055] When the synchronous gear ring 217 is driven to rotate, the arc groove 218 on the synchronous gear ring 217 rotates synchronously. The arc groove 218 rotates and squeezes the push column 214, causing the push column 214 to slide along the strip groove 216. The push column 214 slides and squeezes the annular groove 213, causing the extrusion roller 204 to slide synchronously with the push column 214. At this time, the rectangular block 203 slides along the sliding groove 205, and the spring 206 is compressed. In this way, the extrusion roller 204 unfolds and releases the limit on the piston pin. At this time, the piston pin achieves automatic discharge by its own weight, which improves the efficiency of work.

[0056] Furthermore, the jacking column 214 is slidably disposed on the strip groove 216, and the jacking column 214 is slidably disposed on the arc groove 218;

[0057] Furthermore, the transmission shaft 209 is provided with an adjustment groove 219, a sliding ring 220 is slidably provided on the adjustment groove 219, a synchronous gear 221 is rotatably provided on the transmission shaft 209, wedge block 1 222 and wedge block 223 are respectively provided on the corresponding surfaces of the synchronous gear 221 and the transmission gear 211, wedge block 3 224 is respectively provided at both ends of the sliding ring 220, an adjustment rod 225 is rotatably provided on the sliding ring 220, an electric telescopic rod 1 226 is provided on the furnace body 1, and a discharge port 227 is provided on the furnace body 1;

[0058] like Figure 3As shown, when the electric telescopic rod 226 is activated, the adjusting rod 225 is driven to slide upwards via the electric telescopic rod 226. The adjusting rod 225 then drives the sliding ring 220 to slide upwards along the adjusting groove 219. The wedge block 224 on the sliding ring 220 matches the wedge block 222. When the motor 210 drives the transmission shaft 209 to rotate, the transmission shaft 209 drives the adjusting groove 219 to press against the sliding ring 220, causing the sliding ring 220 to rotate synchronously. The wedge block 224 on the sliding ring 220 presses against the wedge block 222, causing the wedge block 222 and the synchronous gear 221 to rotate synchronously. At this time, the synchronous gear 221 drives the synchronous gear ring 217 to rotate, and the rotation of the synchronous gear ring 217 achieves automatic discharge of the piston pin. Similarly, when the electric telescopic rod 226 is activated, the electric telescopic rod 225 is driven to slide upwards via the electric telescopic rod 226. When rod 226 drives adjusting rod 225 to slide downward, adjusting rod 225 drives sliding ring 220 to slide downward along adjusting groove 219. Wedge block 224 and wedge block 223 on sliding ring 220 are matched. When motor 210 drives transmission shaft 209 to rotate, transmission shaft 209 drives adjusting groove 219 to squeeze sliding ring 220, so that sliding ring 220 rotates synchronously. Wedge block 224 on sliding ring 220 squeezes wedge block 223, so that wedge block 223 and transmission gear 211 rotate synchronously. At this time, transmission gear 211 drives transmission gear ring 212 to rotate. The rotation of transmission gear ring 212 realizes the rotation of squeezing roller 204, so that the contact end of piston pin and squeezing roller 204 is always in a sliding state, avoiding the clamping end of piston pin from being in a stationary state.

[0059] Furthermore, the synchronous gear 221 and the synchronous gear ring 217 are adapted to each other, the transmission gear 211 is rotatably mounted on the transmission shaft 209, the third wedge block 224 is adapted to the first wedge block 222 and the second wedge block 223 respectively, and the adjusting rod 225 is mounted at the output end of the electric telescopic rod 226.

[0060] The synchronous adjustment mechanism 2 drives the contact end between the piston pin and the extrusion roller 204 to always be in a sliding state, avoiding the piston pin clamping end from being in a stationary state, so that the piston pin is heated evenly. This method avoids the situation where the existing clamping mechanism blocks the piston pin, improves the pass rate of piston pin heat treatment. The synchronous adjustment mechanism 2 flexibly clamps the piston and makes the pressure distribution uniform, avoiding the deformation of the piston pin during heat treatment caused by the existing rigid extrusion, thus improving the quality of the piston pin after heat treatment.

[0061] Example 2 further optimizes the intelligent heat treatment production line for piston pins provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, an electric telescopic rod 228 is installed inside the furnace body 1. A connecting block 229 is installed on the electric telescopic rod 228. A support column 230 is installed on the connecting block 229. The support column 230 is slidably installed inside the furnace body 1.

[0062] Start the electric telescopic rod 228. The electric telescopic rod 228 drives the connecting block 229 to slide. The connecting block 229 drives the support column 230 to slide synchronously. The support column 230 pushes the piston pin. The position of the piston pin in the furnace body 1 is adjusted by the sliding of the support column 230, so that the piston pin is at the optimal temperature during heat treatment. By adjusting the position of the piston pin in the furnace body 1, the energy consumption of the furnace body 1 is reduced and the heat treatment efficiency of the piston pin is improved.

[0063] Furthermore, an adjusting shaft 231 is provided on the electric telescopic rod 228, and a connecting block 229 is rotatably mounted on the adjusting shaft 231. A discharge plate 232 is provided inside the furnace body 1.

[0064] Furthermore, the connecting block 229 and the discharge plate 232 are compatible, and the adjusting shaft 231 and the connecting block 229 are connected by a torsion spring;

[0065] When the electric telescopic rod 228 drives the connecting block 229 to slide and unfold and squeeze the discharge plate 232, the discharge plate 232 squeezes the connecting block 229 and makes it rotate. The rotation of the connecting block 229 causes the support column 230 to rotate synchronously. The piston pin on the support column 230 rotates and causes the piston pin to automatically discharge. By rotating the support column 230 and automatically discharging the piston pin, the height of the piston pin's free fall is reduced, the compression deformation of the piston pin during automatic discharge is reduced, and the quality of the piston pin is improved. The elasticity of the torsion spring drives the connecting block 229 to rotate and reset.

[0066] The position of the piston pin in the furnace body 1 is adjusted by the synchronous adjustment mechanism 2 so that the piston pin is at the optimal temperature during heat treatment, thereby reducing the energy consumption of the furnace body 1 and improving the heat treatment efficiency of the piston pin. The synchronous adjustment mechanism 2 drives the piston pin to automatically discharge, reducing the number of steps for workers to discharge the material and improving work efficiency.

[0067] Example 3: A process control technology for an intelligent heat treatment production line for piston pins, comprising the following steps:

[0068] In step S1, the piston pin is placed into the feed inlet 202. The piston pin enters the feed inlet 202 and is pressed and fixed by the extrusion rollers 204. The elasticity of the spring 206 drives the extrusion rollers 204 to press the piston pin, fixing it at the center of the four extrusion rollers 204. The motor 210 is then started. The output of the motor 210 drives the transmission shaft 209 and the transmission gear 211 to rotate synchronously. The transmission gear 211 drives the transmission gear ring 212 to rotate, and the transmission gear ring 212 and the drive gear ring 208 rotate synchronously. The drive gear ring 208 drives the drive gear 207 to rotate, the drive gear 207 rotates and drives the drive shaft 201 to rotate synchronously, the drive shaft 201 drives the rectangular block 203 and the extrusion roller 204 to rotate synchronously, the four extrusion rollers 204 rotate and drive the piston pin to rotate, the piston pin rotates and cooperates with the furnace body 1, the furnace body 1 heats the piston pin so that the piston pin is heated evenly, the extrusion rollers 204 rotate so that the contact end between the piston pin and the extrusion rollers 204 is always in a sliding state;

[0069] Step S2: Activate the electric telescopic rod 226. The electric telescopic rod 226 drives the adjusting rod 225 to slide upward. The adjusting rod 225 drives the sliding ring 220 to slide upward along the adjusting groove 219. The wedge block 224 on the sliding ring 220 matches the wedge block 222. When the motor 210 drives the drive shaft 209 to rotate, the drive shaft 209 drives the adjusting groove 219 to squeeze the sliding ring 220, causing the sliding ring 220 to rotate synchronously. The wedge block 224 on the sliding ring 220 squeezes the wedge block 222, causing the wedge block 222 and the synchronous gear 221 to rotate synchronously. At this time, the synchronous gear 221 drives the synchronous gear ring 217 to rotate, and the arc groove 218 on the synchronous gear ring 217 rotates synchronously. The rotating arc groove 218 rotates and presses the top column 214, causing the top column 214 to slide along the strip groove 216. The top column 214 slides and presses the annular groove 213, causing the pressing roller 204 to slide synchronously with the top column 214. At this time, the rectangular block 203 slides along the sliding groove 205, the spring 206 is compressed, the pressing roller 204 unfolds and releases the limit on the piston pin, and the electric telescopic rod 228 is activated. The electric telescopic rod 228 drives the connecting block 229 to slide, and the connecting block 229 drives the support column 230 to slide synchronously. The piston pin is pushed by the support column 230, and the position of the piston pin in the furnace body 1 is adjusted by the sliding of the support column 230, so that the piston pin is at the optimal temperature during heat treatment.

[0070] Step S3: Start the electric telescopic rod 228. The electric telescopic rod 228 drives the connecting block 229 to slide and unfold and squeeze the discharge plate 232. The discharge plate 232 squeezes the connecting block 229 and makes it rotate. The connecting block 229 rotates and makes the support column 230 rotate synchronously. The piston pin on the support column 230 rotates and makes the piston pin automatically discharge material.
