Description

Technical Field

[0001] This utility model relates to the technical field of quenching processing, and specifically to a furnace feeding conveyor for quenching processing. Background Technology

[0002] In the quenching process, the furnace feeding conveyor is a key piece of equipment that connects the preceding and following processes and ensures the stable entry of the workpiece into the quenching furnace. In the existing technology, the guiding structure is mostly just a simple baffle, lacking a constraint channel that is adapted to the shape of the workpiece, and the guiding surface has no flexible protection. When the workpiece collides with the baffle, it is easy to cause surface scratches or deformation. Its support structure is usually a fixed leg, and the height cannot be adjusted. The existing device lacks an elastic buffer mechanism. When the workpieces accumulate due to uneven rhythm of the preceding process, the subsequent workpieces directly hit the preceding workpieces, which not only causes damage to the surface of the workpieces, but may also cause the conveying to stop due to excessive impact force. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a furnace feeding conveyor for quenching processing. The conveyor uses a guide plate on the conveyor frame to guide the workpiece and maintain its correct posture. The guide plate has a guide groove on its inner side that matches the shape of the workpiece. Combined with anti-collision strips installed in the guide grooves, this reduces surface scratches and deformation of the workpiece during collisions, while also reducing equipment vibration and noise and extending the service life of the guide plate. The outermost layer of the anti-collision strip is a smooth layer, reducing the coefficient of friction with the workpiece. The elastic layer uses rubber to reduce the impact force generated by the workpiece's inertia or vibration through elastic deformation. The buffer layer uses honeycomb-hole sponge to further absorb impact energy. The support layer uses rigid plastic to maintain the structural stability of the anti-collision strip. The height is adjusted by support legs at the bottom of the conveyor frame. The support legs have support columns with external threads on their bases. The connecting column of the adjusting top seat is sleeved on the support column and adjusted by an adjusting nut. The threaded connection and the adjustment nut drive the connecting column to move along the support column, adjusting all support legs to the same height to ensure the conveyor frame is flush with the quenching furnace inlet. An elastic buffer mechanism at the feed end of the conveyor frame prevents workpiece accumulation and collision. The drive component of the elastic buffer mechanism consists of a telescopic cylinder, a connecting shaft, and a sliding optical shaft. The buffer component consists of a mounting base and an elastic pad. The telescopic cylinder drives the sliding optical shaft to move vertically along the mounting bracket via the connecting shaft, causing the elastic pad to rise and contact the workpiece, absorbing impact energy and preventing conveying stagnation. A transmission mechanism ensures synchronous rotation of the conveyor rollers. The motor's speed is reduced and torque amplified by a reducer, and the transmission shaft transmits power to the conveyor rollers via a chain. Each conveyor roller rotates synchronously via a synchronous belt. The conveyor rollers also feature raised or engraved cross-textured anti-slip patterns on their surface, increasing the coefficient of friction with the workpiece and preventing workpiece deviation due to speed differences.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A furnace feeding device for quenching includes a conveyor frame. One end of the conveyor frame is equipped with a transmission mechanism for providing conveying power to the workpiece. The transmission mechanism includes a motor, a reducer, and a drive shaft disposed within the conveyor frame. The output end of the motor is connected to the reducer, and one end of the drive shaft is connected to the output end of the reducer. The drive shaft is mounted within the conveyor frame via a bearing seat. Several conveyor rollers are arranged parallel to each other within the conveyor frame. Both ends of the conveyor rollers are mounted on the conveyor frame via bearing plates. One end of each conveyor roller is connected to the drive shaft via a chain drive, and the other end of each conveyor roller is connected to a synchronous belt drive via a synchronous pulley. The conveyor rollers are used to provide sufficient support force to the workpiece. Two guide plates are arranged opposite each other on both sides of the conveyor frame. The inner side of each guide plate is provided with a guide groove adapted to the shape of the workpiece. An anti-collision strip is provided within the guide groove. The anti-collision strip includes a smooth layer on the outermost layer, an elastic layer on one side of the smooth layer, a buffer layer on one side of the elastic layer, and a support layer on one side of the buffer layer.

[0006] The conveyor frame is a cuboid frame, which is used to meet the length and conveying requirements of the workpiece.

[0007] The bottom of the conveyor frame is provided with multiple support legs, which are used to adjust the height of the conveyor frame.

[0008] The surface of the conveying roller is provided with anti-slip texture, which is used to increase the coefficient of friction and improve the conveying stability of the workpiece.

[0009] The guide plate is fixed to the conveyor frame with bolts, and the height position of the guide plate is adjusted by tightening or loosening the bolts.

[0010] The guide plate has a thickness of 10mm and a height of 100mm.

[0011] The feed end of the conveyor is equipped with an elastic buffer mechanism to prevent workpieces from colliding due to accumulation or uneven spacing, which could cause surface scratches or deformation.

[0012] The elastic buffer mechanism includes a drive assembly mounted on one end of the conveyor frame via a mounting bracket and a buffer assembly mounted on the output end of the drive assembly. The drive assembly is used to drive the buffer assembly to move, and the buffer assembly is used to buffer the impact of the workpiece.

[0013] The drive assembly includes a telescopic cylinder, a connecting shaft located at the output end of the telescopic cylinder, and a sliding optical shaft sleeved on the mounting bracket via a sliding shaft.

[0014] The buffer assembly includes a mounting base at one end of the sliding optical axis and an elastic pad on one side of the mounting base.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The guide plate on the conveyor frame guides the workpiece to maintain the correct posture. The inner side of the guide plate is equipped with a guide groove that matches the shape of the workpiece. In conjunction with the anti-collision strip installed in the guide groove, it reduces surface scratches and deformation of the workpiece when it collides with the workpiece, while reducing equipment vibration and noise and extending the service life of the guide plate. The outermost layer of the anti-collision strip is a smooth layer, which reduces the coefficient of friction with the workpiece. The elastic layer is made of rubber, which reduces the impact force generated by the inertia or vibration of the workpiece through elastic deformation. The buffer layer is made of honeycomb sponge to further absorb the impact energy. The support layer is made of rigid plastic to maintain the structural stability of the anti-collision strip.

[0017] 2. Adjust the height by using the support legs at the bottom of the conveyor frame. The support base of the support leg is equipped with a support column with external threads. The connecting column of the adjusting top seat is sleeved on the support column and connected by the threaded adjusting nut. Turn the adjusting nut to drive the connecting column to move along the support column, so that each support leg is adjusted to the same height, ensuring that the conveyor frame is flush with the inlet of the quenching furnace.

[0018] 3. The elastic buffer mechanism at the feed end of the conveyor frame prevents workpieces from accumulating and colliding. The drive component of the elastic buffer mechanism consists of a telescopic cylinder, a connecting shaft, and a sliding optical shaft. The buffer component consists of a mounting base and an elastic pad. The telescopic cylinder drives the sliding optical shaft to move vertically along the mounting bracket through the connecting shaft, causing the elastic pad to rise and contact the workpiece, absorbing the impact kinetic energy and preventing the conveyor from stopping.

[0019] 4. The transmission mechanism makes the conveyor rollers rotate synchronously. After the motor speed is reduced and the torque is amplified by the reducer, the transmission shaft transmits power to the conveyor rollers through the chain. Each conveyor roller keeps rotating synchronously through the synchronous belt. The cross-textured anti-slip pattern engraved or engraved on the surface of the conveyor roller increases the friction coefficient with the workpiece and avoids the workpiece from shifting due to speed differences.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figure 1-9As shown, this utility model relates to a furnace feeding conveying device for quenching processing, including a conveying frame 1. One end of the conveying frame 1 is provided with a transmission mechanism 2, which is used to provide conveying power to the workpiece. The transmission mechanism 2 includes a motor 20, a reducer 21, and a transmission shaft 22 disposed within the conveying frame 1. The output end of the motor 20 is connected to the reducer 21, and one end of the transmission shaft 22 is connected to the output end of the reducer 21. The transmission shaft 22 is mounted within the conveying frame 1 through a bearing seat 23. A plurality of conveying rollers 3 are arranged in parallel within the conveying frame 1, and both ends of the conveying rollers 3 are respectively connected by a bearing plate 4. Mounted on the conveyor frame 1, one end of the conveyor roller 3 is connected to the drive shaft 22 via a chain 5, and the other end of the conveyor roller 3 is connected to the drive shaft 22 via a synchronous belt 32 via a synchronous pulley 31. The conveyor roller 3 has a diameter of 50mm-65mm and is used to provide sufficient support for the weight of the workpiece and the conveying requirements. The motor 20 is the power source, and the speed is reduced and the torque is amplified by the reducer 21, so that the drive shaft 22 obtains a suitable driving force for conveying the workpiece. The drive shaft 22 synchronously transmits power to the conveyor roller 3 via the chain 5, while the synchronous belt 32 drives the conveyor roller 3. The conveyor rollers 3 rotate synchronously to prevent the workpiece from shifting due to speed differences. Two guide plates 6 are respectively provided on opposite sides of the conveyor frame 1. These guide plates 6 ensure the workpiece maintains the correct posture before entering the quenching furnace, avoiding processing defects caused by posture errors. The inner side of the guide plate 6 is provided with a guide groove 60 that matches the shape of the workpiece. An anti-collision strip 7 is provided within the guide groove 60. The anti-collision strip 7 includes a smooth layer 70 on the outermost layer, an elastic layer 71 on one side of the smooth layer 70, a buffer layer 72 on one side of the elastic layer 71, and a support layer 73 on one side of the buffer layer 72. 7. The outermost smooth layer 70 reduces the coefficient of friction with the workpiece, preventing surface scratches during transport; the elastic layer 71 is formed of elastically deformable rubber, and the buffer layer 72 is formed of sponge with honeycomb holes. The elastic layer 71 and the buffer layer 72 are used to reduce the impact force of the workpiece caused by inertia or vibration; the support layer 73 is formed of rigid plastic to maintain the structural stability of the anti-collision strip 7 and prevent deformation and failure after long-term use. The anti-collision strip 7 allows the workpiece to slide in the guide groove 60, and reduces equipment vibration and noise through flexible protection, while extending the service life of the guide plate 6.

[0033] like Figure 1 , 7As shown in Figure 9, the conveyor frame 1 is a cuboid frame. This conveyor frame 1 is used to meet the length and conveying requirements of the workpiece. The bottom of the conveyor frame 1 is provided with multiple support legs 8, which are used to adjust the height of the conveyor frame 1. Each support leg 8 includes a support base 80, an adjusting top seat 81, and an adjusting nut 82. The support base 80 has a base plate 800 and a support column 801 mounted on the base plate 800. The support column 801 has external threads. The adjusting top seat 81 has a top plate 810 and a support column 801 mounted below the top plate 810. A connecting column 811 is provided with a connecting hole for accommodating the support column 801. The connecting column 811 is sleeved on the support column 801. The adjusting nut 82 is threadedly connected to the support column 801. When adjusting the height of the support leg 8, the height of the adjusting nut 82 and the base plate 800 is measured with a triangle ruler. The adjusting nut 82 is turned by turning the knob with a wrench, so that the adjusting nut 82 rotates along the external thread, driving the connecting column 811 to move along the support column 801, thereby adjusting the other support legs 8 to the same height.

[0034] like Figure 1 , 6 As shown, the surface of the conveyor roller 3 is provided with anti-slip texture 30. The anti-slip texture 30 is used to increase the coefficient of friction and improve the conveying stability of the workpiece. The anti-slip texture 30 is a cross-texture that is raised on the surface of the conveyor roller 3 or a cross-texture that is recessed on the surface of the conveyor roller 3 by engraving, and is arranged around the surface of the conveyor roller 3.

[0035] like Figure 1 As shown, the guide plate 6 is fixed to the conveyor frame 1 by bolts. The guide plate 6 has a thickness of 10mm and a height of 100mm. The side wall of the conveyor frame 1 is provided with several bolt holes, which are arranged linearly at their heights. The installation position of the guide plate 6 can be adjusted by adjusting the height of the bolts.

[0036] like Figure 1 , 7As shown in Figure -8, the feed end of the conveyor frame 1 is equipped with an elastic buffer mechanism 9. This elastic buffer mechanism 9 is used to prevent collisions caused by accumulation or uneven spacing of workpieces during conveying, which could result in surface scratches or deformation. The elastic buffer mechanism 9 includes a drive assembly 91 mounted on one end of the conveyor frame 1 via a mounting bracket 90 and a buffer assembly 92 located at the output end of the drive assembly 91. The drive assembly 91 is used to drive the buffer assembly 92 to move, and the buffer assembly 92 is used to buffer the impact of the workpieces. The drive assembly 91 includes a telescopic cylinder 910, a connecting shaft 911 located at the output end of the telescopic cylinder 910, and a sliding optical shaft 913 mounted on the mounting bracket 90 via a sliding bushing 912. The telescopic cylinder 910 is the power source, which moves the buffer assembly 92 vertically along the mounting bracket 90 via the connecting shaft 911. By adjusting the telescopic cylinder 910, the elastic pad 921 of the buffer assembly 92 is driven to rise. When the elastic pad 921 contacts and absorbs the impact kinetic energy of the workpiece, it prevents the workpiece from stopping due to excessive buffering force. The buffer assembly 92 includes a mounting seat 920 at one end of the sliding optical shaft 913 and an elastic pad 921 on one side of the mounting seat 920. A connecting plate is provided on each side of the mounting seat 920. The connecting plate has an L-shaped cross section. One connecting plate is fixedly connected to one end of the sliding optical shaft 913, and the other connecting plate is fixedly connected to one end of the connecting shaft 911.

[0037] Workflow: First, based on the workpiece size and quenching furnace height, adjust the overall height of the conveyor frame 1 by adjusting the adjusting nuts 82 of the support legs 8 to ensure that the conveyor rollers 3 are flush with the quenching furnace inlet; after the transmission mechanism 2 starts the motor 20, the output power of the motor 20 is reduced in speed and amplified in torque by the reducer 21, and then transmitted to the conveyor rollers 3 via the chain 5 through the transmission shaft 22. At the same time, each conveyor roller 3 rotates synchronously through the synchronous belt 32 to prevent the workpiece from shifting due to speed differences; the anti-slip texture 30 on the surface of the conveyor rollers 3 ensures stable conveying of the workpiece; when the workpiece enters the conveyor frame 1, the guide grooves 60 of the guide plates 6 on both sides are aligned with the shape of the workpiece. The matching constraint channel guides it to maintain the correct posture. The anti-collision strip 7 in the guide groove 60 buffers the impact force of the workpiece. The telescopic cylinder 910 of the elastic buffer mechanism 9 drives the connecting shaft 911, which drives the sliding optical shaft 913 to move upward along the mounting bracket 90, so that the elastic pad 921 of the buffer assembly 92 rises to contact the workpiece, absorbs the impact kinetic energy of the workpiece and stops it from moving forward. At this time, the motor 20 stops working. After the previous workpiece is transferred, the telescopic cylinder 910 drives the connecting shaft 911 to descend, so that the elastic pad 921 of the buffer assembly 92 is separated from the workpiece. The motor 20 works again to transport the workpiece to the next station, and the cycle continues.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
