Description

Technical Field

[0001] This utility model relates to the field of screw technology, and in particular to a screw thread rolling device. Background Technology

[0002] A thread rolling machine consists of two identical rolling plates with the same thread profile and helix angle as the bolt thread. As the rolling plates move against each other, they roll threads onto the bolt blank between them. One round trip of the rolling plates completes the processing of one bolt thread, making it quite fast. Thread rolling is mostly used for processing small bolts.

[0003] Referring to the patent document with application number "CN202222812005.7" entitled "A thread rolling machine for screw processing", this patent document uses a thread rolling wheel to rotate the screw clockwise, so that the screw is processed by thread rolling under the action of the thread rolling plate and the thread rolling wheel. Compared with the two thread rolling plates repeatedly rolling back and forth, the time of repeated rolling of the thread rolling plate is reduced, thereby improving the screw processing effect and thus improving the efficiency of the entire thread rolling machine.

[0004] Existing technology requires the oil return assembly to re-extract the lubricating oil collected inside the oil receiving chamber into the lubricating oil tank during operation, thereby reducing the use of lubricating oil and saving costs. This improves the lubrication effect when the thread rolling machine is processing screws. However, the existing lubrication method can only add lubricating oil to the equipment once every certain period of time during screw processing. It is not possible to continuously add lubricating oil during the thread rolling process. Therefore, the lubrication effect when the screw is thread rolled is low. At the same time, the thread rolling equipment cannot clean the debris generated during screw processing during operation. The debris adheres to the screw surface and affects subsequent processing.

[0005] To address this, we designed a screw thread rolling device. Utility Model Content

[0006] The purpose of this invention is to provide a screw thread rolling device to solve the problems of lubrication and cleaning in existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A screw thread rolling device includes a support platform, a support seat disposed on the side wall of the support platform, a cylinder disposed on the top of the support seat, a piston rod disposed at the output end of the cylinder, a first rolling plate disposed at the end of the piston rod away from the cylinder, and a second rolling plate disposed on the side wall of the support platform, and further includes;

[0009] The oil pump assembly includes a first connecting rod disposed at the bottom of a first washboard, a push rod disposed on the side wall of a second washboard, an air cylinder disposed at the end of the push rod away from the second washboard, and an oil injection assembly disposed at the output end of the air cylinder.

[0010] A chip removal assembly is disposed between the support base and the first washboard for cleaning iron filings adhering to the outer wall of the screw.

[0011] Preferably, the oil injection assembly includes a mounting box disposed on the side wall of the second washboard via a connecting rod, an oil reservoir disposed inside the mounting box for storing lubricating oil, a connecting pipe disposed between the oil reservoir and the air cylinder, and an oil nozzle disposed on the side wall of the oil reservoir and extending to the space between the first and second washboards.

[0012] Preferably, the top of the oil storage tank is provided with an oil delivery pipe that passes through the mounting box and extends outward, and the top of the oil storage tank is provided with a one-way valve.

[0013] Preferably, the first rubbing plate has an air storage chamber inside, and the lint removal assembly includes a blower disposed on the top of the support base, an air pipe disposed between the output end of the blower and the first rubbing plate, and a number of jet nozzles disposed on the top of the first rubbing plate and connected to the air storage chamber.

[0014] Preferably, the bottom of the second washboard is further provided with a cleaning assembly, which includes a cleaning chamber disposed at the bottom of the second washboard via a second connecting rod, a motor disposed on the side wall of the cleaning chamber, and a cleaning fan blade disposed at the output end of the motor.

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

[0016] 1. This utility model, through the setting of the first connecting rod and the mounting box, enables the first washboard to drive the screw to be processed on the second washboard. Under the repeated stretching action of the cylinder, lubricating oil can be sprayed onto the first washboard, thereby ensuring that each screw maintains a lubricating effect during processing. This prevents the first washboard from losing its lubricating effect and affecting the processing efficiency of the screw, thereby improving the overall processing effect of the screw.

[0017] 2. By setting up the jet head and cleaning fan blades, this utility model can effectively reduce the amount of water debris remaining on the screw and the second cleaning plate when the first scrubbing plate drives the screw to process. This avoids errors in the next screw processing that could render the screw unusable. At the same time, the cleaning fan blades can drive the water flow in the cleaning chamber to form a vortex, which can improve the removal of metal debris from the screw surface and cool it down, thereby improving the screw's shaping and cleaning effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-5 A screw thread rolling device includes a support platform 303, a support seat disposed on the side wall of the support platform 303, a cylinder 1 disposed on the top of the support seat, a piston column 101 disposed at the output end of the cylinder 1, a first rubbing plate 2 disposed at the end of the piston column 101 away from the cylinder 1, and a second rubbing plate 3 disposed on the side wall of the support platform 303. It also includes an oil pump assembly and a chip removal assembly. The oil pump assembly is disposed between the first rubbing plate 2 and the second rubbing plate 3 and can spray lubricating oil onto the screw surface when the first rubbing plate 2 reciprocates. The chip removal assembly is disposed between the support seat and the first rubbing plate 2 and is used to clean iron filings adhering to the outer wall of the screw.

[0026] When thread rolling is required, the screw is first placed between the first rolling plate 2 and the second rolling plate 3. Then, the cylinder 1 is started, and the piston column 101 pushes the first rolling plate 2 to reciprocate relative to the second rolling plate 3, thereby working with the second rolling plate 3 to roll the screw's outer wall. At the same time, through the oil pump assembly, lubricating oil can be evenly sprayed onto the screw, the first rolling plate 2, and the second rolling plate 3 during the reciprocating motion of the first rolling plate 2, thereby lubricating the equipment and the screw. Compared with the prior art, which can only provide oil once every certain period of time, this application can provide oil lubrication continuously during the thread rolling process, thereby improving the thread rolling effect. In addition, through the chip removal assembly, the iron filings generated by the screw during the thread rolling process can be cleaned, preventing iron filings from adhering to the outer wall of the screw after thread rolling, thereby improving the thread rolling quality.

[0027] Specifically, the oil pump assembly includes a first connecting rod 201 disposed at the bottom of the first washboard 2, a push rod 202 disposed on the side wall of the second washboard 3, an air cylinder 203 disposed at the end of the push rod 202 away from the second washboard 3, and an oil injection assembly disposed at the output end of the air cylinder 203.

[0028] The oil injection assembly includes a mounting box 7 disposed on the side wall of the second rubbing plate 3 via a connecting rod, an oil reservoir 703 disposed inside the mounting box 7 for storing lubricating oil, a connecting pipe 701 disposed between the oil reservoir 703 and the air cylinder 203, and an oil nozzle 705 disposed on the side wall of the oil reservoir 703 and extending to the space between the first rubbing plate 2 and the second rubbing plate 3.

[0029] The top of the oil storage tank 703 is provided with an oil delivery pipe 702 that passes through the mounting box 7 and extends outward, and the top of the oil storage tank 703 is provided with a one-way valve 704;

[0030] First, connect the oil pump to the oil supply pipe 702. Start the oil pump to input lubricant into the oil storage tank 703. Therefore, when the screw is placed between the first rubbing plate 2 and the second rubbing plate 3 for thread rolling, the reciprocating first rubbing plate 2 will drive the push rod 202 at its bottom to reciprocate. The first connecting rod 201 will reciprocate under the restriction of the slide groove 301. The push rod 202 will squeeze the air cylinder 203 back and forth, so that the air cylinder 203 will continuously inflate the oil storage tank 703. Under the action of air pressure, the lubricating oil inside the oil storage tank 703 will be squeezed into several oil spray nozzles 705. Finally, when the oil is sprayed by multiple oil spray nozzles 705 onto the first rubbing plate 2, the second rubbing plate 3 and the screw, it can not only lubricate the screw, but also lubricate the equipment, preventing the equipment and screw from being damaged under long-term friction. In addition, it can also provide oil lubrication during the thread rolling process, improving the thread rolling effect of the screw.

[0031] The first rubbing board 2 has an air storage chamber inside. The lint removal assembly includes a blower 5 set on the top of the support base, an air pipe set between the output end of the blower 5 and the first rubbing board 2, and several jet nozzles 204 set on the top of the first rubbing board 2 and connected to the air storage chamber.

[0032] The gas storage chamber inside the first washboard 2 is a cavity for storing gas. When the cylinder 1 is started, the blower 5 set on the support platform 303 will also start. During operation, the blower 5 transmits the collected gas to the gas storage chamber inside the first washboard 2 through the air pipe. Under the continuous input of the blower 5, the gas in the storage chamber is discharged from several jet nozzles 204 on the top of the first washboard 2. In this way, when the first washboard 2 is used to roll the screw, the jet nozzles 204 can blow air onto the first washboard 2, the second washboard 3, and the screw, reducing the residue of metal debris on their surfaces. At the same time, the air pipe is an existing flexible hose, which can be connected to the output end of the blower 5 without disconnecting when the cylinder 1 drives the first washboard 2, thereby reducing the retention of metal debris. In addition, the blowing can also cool down the first washboard 2, the second washboard 3, and the screw, preventing the first washboard 2, the second washboard 3, and the screw from being damaged due to excessive temperature caused by mutual friction.

[0033] The bottom of the second washboard 3 is also provided with a cleaning assembly, which includes a cleaning chamber 4 set at the bottom of the second washboard 3 via a second connecting rod 302, a motor 6 set on the side wall of the cleaning chamber 4, and a cleaning fan blade 401 set at the output end of the motor 6.

[0034] After the screw completes the thread-rolling work of the first washboard 2 and the second washboard 3, it will fall into the cleaning chamber 4 at the bottom of the second washboard 3. The cleaning chamber 4 contains purified water. After the screw falls into the cleaning chamber 4, it will first come into contact with the purified water under the impact effect, cleaning away any metal debris that may be adsorbed on the surface. Then, the cleaning fan blades 401 in the cleaning chamber 4, under the output of the motor 6, will agitate the purified water and form a vortex. This allows the screw to follow the vortex and come into contact with the inner wall of the cleaning chamber 4 and the cleaning fan blades 401, thereby cleaning away the metal debris adsorbed inside the screw threads. At the same time, the vortex-shaped purified water can prevent the screw from getting stuck on the inner wall corners after falling into the cleaning chamber 4, thus improving the cleaning efficiency of the screw after processing. In order to ensure that each screw is cleaned, the motor 6 needs to be started synchronously when the cylinder 1 is started, so that the purified water in the cleaning chamber 4 can enter the vortex state as soon as possible.

[0035] The working principle of this utility model is as follows: First, cylinder 1 is started. Cylinder 1 transmits power to the first rubbing plate 2 through piston rod 101. The first rubbing plate 2 drives the screw to perform thread rolling on the second rubbing plate 3. The first connecting rod 201 at the bottom of the first rubbing plate 2 pulls the push rod 202 to generate air pressure on the air cylinder 203, causing the lubricating oil in the mounting box 7 to be sprayed out from the oil nozzle 705 along with the air pressure. At the same time, it is evenly sprayed on the screw, the first rubbing plate 2, and the second rubbing plate 3. After cylinder 1 is started, the blower 5 and motor 6 on the support platform 303 need to be started simultaneously to ensure that the jet nozzle 204 on the first rubbing plate 2 can output air and reduce the screw, the first rubbing plate 2, and the second rubbing plate 3. Metal debris residue on the first and second washboards 2 and 3 ensures that after the screws fall into the cleaning chamber 4, the screws can be cleaned more effectively by the water vortex, reducing the likelihood of screws getting stuck in the cleaning chamber 4. The water in the cleaning chamber 4 also reduces the high temperature of the screws processed by the first and second washboards 2 and 3. Through the first connecting rod 201 and the mounting box 7, lubricating oil can be sprayed onto the first washboard 2 by the repeated stretching action of the cylinder 1, thus keeping each screw lubricated during processing and preventing the first washboard 2 from losing its lubricating effect, which would affect the processing efficiency of the screws and improve the overall processing effect of the screws.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
