[0001] The present application relates to the field of bolt processing, and in particular to a post-processing device of a thread rolling machine for bolt processing. Background Art

[0002] The thread rolling machine is a mature device used to form threads on cylindrical workpieces. It is generally composed of a stationary thread rolling plate and a movable thread rolling plate that move relative to each other to achieve thread rolling. The bolts after thread rolling are easily contaminated with a lot of waste chips, and the thread rolling oil contaminated during thread rolling makes the bolts need to be cleaned before packaging.

[0003] For example, a fully automatic bolt thread rolling machine and its process with publication number CN118180299A, in which the threaded bolts are moved into the mounting holes of the fixed plate of the conveyor belt in sequence, so that the conveyor belt can drive the bolts forward individually, and then the bolts are moved to the top of the cleaning ring. The cleaning ring is provided with several cleaning heads to spray cleaning liquid onto the bolts, and the cleaning ring can also be raised and lowered to achieve more comprehensive cleaning of the bolts.

[0004] With regard to the above-mentioned related technologies, the cleaning ring can only clean the bolt screw, while the bolt head cannot be cleaned and is still easily contaminated with waste chips and threading oil, and the cleaning is not comprehensive enough. Summary of the invention

[0005] In order to more comprehensively clean the thread-rolled bolts, the present application provides a post-processing device for a thread rolling machine for bolt processing.

[0006] The present application provides a post-processing device for a thread rolling machine for bolt processing, which adopts the following technical solution.

[0007] A post-processing device for a thread rolling machine for bolt processing, comprising a conveyor belt that can be circulated and driven, and a belt plate fixedly connected to the conveyor belt and used to convey the threaded bolts one by one in sequence, wherein a front frame and a rear frame are provided around the conveyor belt, the front frame is detachably connected to a top nozzle that faces the bolt head and sprays a cleaning liquid from top to bottom, the rear frame is detachably connected to a bottom nozzle that faces the bottom of the screw rod of the bolt and sprays a cleaning liquid from bottom to top, the rear frame is detachably connected to a magnetic suction piece that can force the bolt to move upward so that there is a distance between the bolt head and the belt plate, and a liquid passage port is penetrated at the position of the belt plate opposite to the bolt head for the cleaning liquid sprayed by the bottom nozzle to pass through.

[0008] By adopting the above technical solution, the surrounding area and upper surface of the bolt head are cleaned when passing through the top nozzle, and the bolt is adsorbed and moved upward when passing through the bottom nozzle, so that there is a gap between the bolt head and the strip plate, so that the bottom nozzle can clean the bolt stud and the bottom surface of the head, thereby improving the comprehensiveness of the bolt cleaning.

[0009] Optionally, the liquid passage openings are arranged in several circles, and several liquid passage openings are arranged in each circle around the center line of the bolt, and the liquid passage openings in two adjacent circles are arranged in a staggered manner.

[0010] By adopting the above technical solution, the cleaning liquid sprayed by the top nozzle can contact the bottom surface of the bolt head more, so that when the distance between the stud and the strip plate of the bolt is small, the bottom nozzle can also fully clean the bottom surface of the bolt head.

[0011] Optionally, the top nozzle is located in front of the bottom nozzle along the bolt conveying direction.

[0012] By adopting the above technical solution, the bolt head is cleaned first, and then the bolt screw is cleaned, so as to prevent a part of the cleaning liquid mixed with threading oil from flowing down to the bolt screw part that has been cleaned when cleaning the bolt head, thereby reducing the occurrence of insufficient and incomplete cleaning.

[0013] Optionally, the rear frame is equipped with two synchronous belts that can perform circulating transportation along the transmission direction of the conveyor belt. The two synchronous belts are fixedly connected to a group of baffles. The baffles in the two groups correspond to each other one by one. The ends of the two corresponding baffles can be close to each other. The two baffles that can be close to each other are provided with magnetic ports on one end that can be directly opposite to the bolt head and can prevent the bolt head from passing through. The transmission speed of the synchronous belt is consistent with the transmission speed of the conveyor belt.

[0014] By adopting the above technical solution, the bolt head is not easily in direct contact with the magnetic suction part, so as to prevent the cleaning liquid remaining on the bolt head from contaminating the magnetic suction part. It can also prevent the bolt from generating friction with the magnetic suction part during the process of moving forward with the conveyor belt, which helps to improve the service life of the magnetic suction part.

[0015] Optionally, the rear frame is detachably connected with a bottom drying pipe facing the bottom of the screw rod of the bolt and sending hot air from bottom to top, and a top drying pipe facing the bolt head and sending hot air from top to bottom.

[0016] By adopting the above technical solution, the cleaned bolt head and screw rod are dried.

[0017] Optionally, the bottom baking tube is located in front of the top baking tube in the conveying direction of the bolts, the bottom baking tube is directly opposite to the magnetic attraction component, and there is a distance between the top baking tube and the area directly below the magnetic attraction component.

[0018] By adopting the above technical solution, the bolt screw is first dried when the bolt is attracted by the magnetic element and fits against the baffle, and then the bolt head is dried again when the bolt is away from the magnetic element so that the bolt head abuts against the belt plate, so that the bolt is fully dried.

[0019] Optionally, the rear frame is detachably connected to a plate drying tube capable of delivering hot air to the belt plate, the plate drying tube is inclined and located between the bottom drying tube and the top drying tube, and the bottom end of the plate drying tube is further forward than the upper end in the bolt transmission direction.

[0020] By adopting the above technical solution, when the bolt abuts against the baffle, that is, when there is a gap between the bolt head and the strip plate, the plate drying tube can send hot air toward the bolt head and the upper surface of the strip plate for drying, so that when the bolt falls away from the magnetic suction part, it is difficult for cleaning liquid to exist on the surface of the strip plate where the bottom surface of the bolt head contacts.

[0021] Optionally, there are inclined drying tubes around the bottom drying tube that can deliver hot air to the bolts, and two inclined drying tubes are arranged along the bolt conveying direction, and the closer the two inclined drying tubes are to the two ends of the belt plate, the smaller the distance between them.

[0022] By adopting the above technical solution, it is difficult for cleaning liquid to remain in the screw groove part of the screw rod of the bolt.

[0023] Optionally, the front frame and the rear frame are detachably connected with a liquid receiving box for receiving the cleaning liquid, and the lowest point of the bottom surface of the liquid receiving box is connected with a drain pipe for conveying the cleaning liquid.

[0024] By adopting the above technical solution, the cleaning liquid can be received and recovered for treatment.

[0025] Optionally, the surface of the belt plate against which the bolt head abuts is fixedly connected to two liquid baffles, the liquid baffles are located directly above the area of ​​the liquid receiving box for the cleaning liquid to enter, the position where the belt plate is inserted into the bolts is located between the two liquid baffles, and the projection of the belt plate on the liquid baffles is completely located within the surface of the liquid baffles.

[0026] By adopting the above technical solution, it is difficult for the cleaning liquid to flow along the belt plate to the conveyor belt.

[0027] In summary, the present application includes at least the following beneficial effects.

[0028] When passing through the top nozzle, the surrounding area and upper surface of the bolt head are cleaned. When passing through the bottom nozzle, the bolt is adsorbed and moved upward so that there is a gap between the bolt head and the strip plate, so that the bottom nozzle can clean the bolt stud and the bottom surface of the head, thereby improving the comprehensiveness of the bolt cleaning.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a post-processing device for a thread rolling machine for bolt processing, referring to Figure 1 , including two conveyor belts 1 placed on the ground, the conveyor belts 1 are specifically belt conveyors, a belt plate 2 is fixedly connected between the two conveyor belts 1, the length direction of the belt plate 2 is the width direction of the conveyor belt 1, the belt plates 2 form two upper and lower rows on the conveyor belt 1, and a plate hole 45 for inserting a screw rod of a bolt is opened in the center of the belt plate 2, so that each belt plate 2 can drive one bolt forward at a time.

[0033] Reference Figure 1 and Figure 2 A front frame 3 is placed on the ground at the front end of the conveyor belt 1. The front frame 3 is detachably connected to a top spray head 5 located above the belt plate 2. The top spray head 5 is connected to an external diaphragm pump to spray the cleaning liquid vertically downward to form a liquid column to clean the top surface and the surrounding area of ​​the bolt head. A rear frame 4 is placed on the ground at the middle and rear part of the conveyor belt 1. The rear frame 4 is detachably connected to a bottom spray head 51 located between the upper and lower rows of belt plates 2. The bottom spray head 51 is connected to an external diaphragm pump to spray the cleaning liquid vertically upward to form a liquid column. In addition, the rear frame 4 is detachably connected to a magnetic suction member 52 located above the conveyor belt 1. The magnetic suction member 52 can be an electromagnet or a permanent magnet, so that the bolts located in the belt plate 2 can be attracted and moved upward by magnetic force.

[0034] Reference Figure 2, the rear frame 4 is equipped with two synchronous belts 43 that are circulated along the transmission direction of the conveyor belt 1. The rear frame 4 is provided with a pulley and a motor to drive the synchronous belt 43 for transmission. Both synchronous belts 43 are fixedly connected with a set of baffles 54. The two sets of baffles 54 correspond to each other one by one. The two ends of the corresponding two baffles 54 can be close to each other, and the ends of the two close baffles 54 are provided with a magnetic port 55. The transmission speed of the synchronous belt 43 is consistent with that of the conveyor belt 1. The corresponding two baffles 54 can be located directly above a belt plate 2 and move synchronously at a distance. The baffle 54 is located between the magnetic suction piece 52 and the belt plate 2, so that when the bolt is adsorbed and moved upward, its head can abut against the lower surface of the baffle 54, so that it is not easy for the bolt head and the magnetic suction piece 52 to directly contact each other. And the top spray head 5 is located in front of all the baffles 54 in the direction of bolt transmission, so that before the baffle 54 moves directly above the bolt, the top spray head 5 will clean the bolt head. The bottom spray head 51 is located directly below the magnetic attraction member 52 , so that the bolt will move to the bottom spray head 51 for cleaning only after the bolt moves upward.

[0035] Reference Figure 2 and Figure 3 , the belt plate 2 is provided with several circles of liquid ports 53, each circle of liquid ports 53 is provided with several circles around the plate hole 45, and the adjacent circles of liquid ports 53 are staggered, so that the cleaning liquid sprayed by the bottom nozzle 51 can pass through the liquid ports 53 to clean the bottom surface of the bolt head more comprehensively. In addition, the front frame 3 and the rear frame 4 are detachably connected with the same liquid receiving box 58 for receiving the cleaning liquid, and the lowest point of the bottom surface of the liquid receiving box 58 is connected with a drain pipe 59, which is connected to an external diaphragm pump to regularly discharge the cleaning liquid in the liquid receiving box 58. In addition, each belt plate 2 is fixedly connected with two liquid baffle plates 41, and the plate hole 45 is located between the two liquid baffle plates 41. The projection of the belt plate 2 on the liquid baffle plate 41 is completely located within the surface of the liquid baffle plate 41, so that when the top nozzle 5 sprays the cleaning liquid onto the upper surface of the belt plate 2, the cleaning liquid is not easy to flow along the belt plate 2 to the conveyor belt 1. At the same time, when the belt plate 2 moves to the positions of the bottom nozzle 51 and the top nozzle 5, the liquid baffle plate 41 is located directly above the opening of the liquid receiving box 58 for receiving the cleaning liquid.

[0036] Reference Figure 2The rear frame 4 is detachably connected to a bottom drying tube 56, two inclined drying tubes 42, a plate drying tube 44 and a top drying tube 57. The bottom drying tube 56, the inclined drying tube 42, the plate drying tube 44 and the top drying tube 57 are all connected to an external electric hot air blower to send out hot air. The bottom drying tube 56 is located in front of the top drying tube 57 along the conveying direction of the conveyor belt 1. The two inclined drying tubes 42 are located on both sides of the bottom drying tube 56 in a one-to-one correspondence. The connection direction of the two inclined drying tubes 42 is consistent with the conveying direction of the conveyor belt 1. The distance between the upper air outlets of the two inclined drying tubes 42 is the smallest, and the inclined drying tube 42 and the bottom drying tube 56 are both located directly below the magnetic attraction member 52, so that when the bolt is magnetically attracted to the baffle 54, the inclined drying tube 42 and the bottom drying tube 56 can fully dry the bottom surface of the bolt head, the stud of the bolt and the inside of the screw groove.

[0037] Reference Figure 2 The top drying tube 57 is far away from the magnetic member 52, so that when the bolt is no longer attracted by the magnetic member 52 and the baffle 54 is no longer located directly above the bolt, the bottom air outlet of the top drying tube 57 can dry the bolt head. The plate drying tube 44 is located between the top drying tube 57 and the magnetic member 52, and the air outlet of the plate drying tube 44 is tilted downward, and the lower end of the plate drying tube 44 is the front end in the conveying direction of the conveyor belt 1, so that when the bolt abuts against the baffle 54 and is dried by the inclined drying tube 42 and the bottom drying tube 56, the plate drying tube 44 can dry the peripheral surface of the plate hole 45 and the liquid outlet 53 of the belt plate 2, so that the bolt is not easily contaminated by the cleaning liquid remaining on the upper surface of the belt plate 2 after falling.

[0038] The implementation principle of the post-processing device of a thread rolling machine for bolt processing in the embodiment of the present application is as follows: the bolt enters the plate hole 45 and moves forward along with the transmission of the conveyor belt 1, first passes through the top spray head 5 to clean the bolt head, then the bolt moves between the two synchronous belts 43, the two baffles 54 move to the top of the bolt and move forward synchronously with the bolt, when the bolt passes directly below the magnetic suction piece 52, it is adsorbed and moved upward to abut against the baffle 54, and then the bottom spray head 51 cleans the bolt's screw and the bottom surface of the head. The bolt then moves through the inclined drying tube 42 and the bottom drying tube 56 so that the bolt's screw and the bottom surface of the head can be dried, and at the same time, the plate drying tube 44 will also dry the upper surface of the belt plate 2. Then the bolt moves away from the magnetic suction piece 52 so that the bolt can fall and abut against the belt plate 2, and then the top drying tube 57 dries the bolt head, and then the conveyor belt 1 sends the bolt to the downward station for subsequent processing.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
