Description

Technical Field

[0001] The present application relates to the technical field of cold heading machine bodies, and in particular to a cold heading machine for lighter grinding wheels. Background Art

[0002] A cold heading machine is a specialized piece of machinery used for cold working metals. It's primarily used to plastically deform metal materials at room temperature into components of various sizes and shapes. Its operating principle is to place the blank in the mold of an automatic cold heading machine or press at room temperature. Pressure is then applied to the mold, and the relative motion of the upper and lower dies allows the blank to be formed within the cavity.

[0003] In the related art, the surface of the tubular metal parts produced by the cold heading machine body will be adhered to oil stains, and metal debris will remain inside. When discharging, it will slide naturally through the inclined guide plate. During the sliding process, it is easy to cause the tubular metal parts to be discharged quickly, resulting in the lubricating oil on the surface and the metal debris inside cannot be cleaned in time, and it is impossible to provide a clean foundation for subsequent processing. As a result, manual cleaning is required in the later stage, and the operation is relatively complicated, affecting the efficiency of processing and production. Summary of the Invention

[0004] In order to improve processing efficiency, the present application provides a cold heading machine for lighter grinding wheels.

[0005] A cold heading machine for lighter grinding wheels comprises a cold heading machine body, a discharge port is provided on the cold heading machine body, and a cleaning device for cleaning the surface of the lighter grinding wheel produced by the cold heading machine body, the cleaning device comprising:

[0006] A guide rail is connected to the discharge port of the cold heading machine body, and the guide rail includes a raised section for reducing the sliding speed of the lighter grinding wheel;

[0007] A material limiting rod is inserted into the guide rail and is connected to a drive motor;

[0008] The first air duct is located above the guide rail and is connected to a forward and reverse blower through a pipe. The first air duct is provided with a plug-in slot. The forward and reverse blower draws air through the first air duct, so that the lighter grinding wheel is inserted into the plug-in slot.

[0009] The spiral duct is composed of multiple spiral plates. The spiral duct is connected to the guide rail through a guide pipe. The forward and reverse blower blows air through the first air duct, causing the lighter grinding wheel to enter the spiral duct along the guide rail and the guide pipe.

[0010] When the lighter grinding wheel slides in the spiral pipe, the spiral plate contacts the surface of the lighter grinding wheel, causing friction between the lighter grinding wheel and the spiral plate. The lighter grinding wheel rotates under the action of its own weight and friction.

[0011] The collecting box is located below the spiral plate, and a buffer block is provided in the collecting cylinder.

[0012] By adopting the above technical solution, the cleaning device can clean the surface of the lighter grinding wheel, and the raised section of the guide rail can reduce the sliding speed of the lighter grinding wheel, which is convenient for subsequent operation; the material limiting rod and the drive motor can control the unloading of the lighter grinding wheel to avoid accumulation; the forward and reverse rotating fans draw air through the first air duct to insert the lighter grinding wheel into the plug-in slot, which is convenient for cleaning the residue on the inner wall, and the air jet pushes the lighter grinding wheel into the spiral pipe; the spiral plate of the spiral pipe rubs with the lighter grinding wheel to make it rotate, and uses centrifugal force to throw off the oil stains on the surface; the buffer block in the collection box can reduce the damage when the lighter grinding wheel falls.

[0013] Optionally, an inner wall of the plug-in slot is provided with an elastic surface, the elastic surface is provided in a trumpet shape and the opening thereof is consistent with the opening of the plug-in slot.

[0014] By adopting the above technical solution, the elastic surface and the lighter grinding wheel are continuously squeezed, which can slow down the sliding speed of the lighter grinding wheel and increase the time the lighter grinding wheel is adsorbed, which is conducive to improving the cleaning effect.

[0015] Optionally, the bottom of the plug-in slot is connected to a pressure sensing piece, which is electrically connected to a drive motor and a forward and reverse fan. When the lighter grinding wheel collides with the pressure sensing piece, the drive motor controls the material limiting rod to move out of the guide rail, and the forward and reverse fan ejects air through the first air duct.

[0016] By adopting the above technical solution, the unloading of the cold heading machine body can be controlled, the accumulation of the lighter grinding wheel on the guide rail can be avoided, and the metal debris on the inner wall of the lighter grinding wheel can be completely cleaned, so that the lighter grinding wheel can be normally transported on the guide rail and spiral pipeline for subsequent cleaning operations.

[0017] Optionally, the guide pipe is connected to an oil retaining pipe, and the oil retaining pipe is sleeved outside the spiral pipe.

[0018] By adopting the above technical solution, when the lighter grinding wheel slides into the spiral pipe along the feeding section and guide tube of the guide rail under the blowing drive of the forward and reverse blower, the oil retaining pipe can be used to collect the oil stains thrown out by the centrifugal rotation of the lighter grinding wheel.

[0019] Optionally, the spiral plate is connected to a fan blade away from the guide tube, and the spiral extension direction of the fan blade is opposite to the spiral extension direction of the spiral plate; the end of the fan blade is fixedly connected to a drive ring, and the drive ring is connected to a rotating motor through a belt; a rotating shaft is fixedly connected to the oil retaining tube, and the end of the spiral plate away from the fan blade is connected to the rotating shaft.

[0020] By adopting the above technical solution, the rotating motor drives the driving ring to rotate through the belt, so that the fan blades rotate to form an airflow flowing toward the inner wall of the spiral pipe. Part of the airflow flows along the trumpet-shaped first partition, converges and concentrates, thereby increasing the flow rate of the airflow flowing into the spiral pipe. At the same time, the spiral plate rotates to form an airflow toward the inner wall of the oil baffle pipe and the upper surface of the first partition; when the lighter grinding wheel slides into the spiral pipe under the action of the first air duct and its own weight, the rotation of the spiral plate will drive the lighter grinding wheel to rotate further, increasing the rotation speed of the lighter grinding wheel. The airflow formed by the fan blades slows down the falling speed of the lighter grinding wheel, increases the residence time of the lighter grinding wheel in the spiral pipe, and thereby improves the cleanliness of the surface of the lighter grinding wheel; the airflow formed by the fan blades flows through the middle of the lighter grinding wheel, and blows out the remaining metal debris in cooperation with the own weight of the lighter grinding wheel; based on this structure, the wind force of the forward and reverse fans can be adaptably increased, thereby improving the cleaning speed and processing efficiency of the lighter grinding wheel.

[0021] Optionally, a transition rod is connected between the spiral plate and the fan blades, a rotating sleeve is provided on the transition rod, a first partition is provided on the outer sleeve of the rotating sleeve, the first partition is trumpet-shaped and the opening is opened toward the fan blades; an oil storage ring is provided on the outer sleeve of the oil retaining pipe, the oil storage ring is connected to the inside of the oil retaining pipe, one end of the oil storage ring is connected to the first partition, and the oil storage ring is connected to the oil storage tank through a pipeline.

[0022] By adopting the above technical solution, a transition rod is set to connect the spiral plate and the fan blades, and the rotating sleeve and the trumpet-shaped first partition are used, in conjunction with the oil storage ring arranged on the outer surface of the oil baffle pipe and the connected oil storage tank, the oil stains attached to the inner wall of the oil baffle pipe due to the rotation of the lighter grinding wheel and flowing onto the first partition under the action of gravity can be thrown out and transported to the oil storage tank through the oil storage ring and the pipeline for recovery.

[0023] Optionally, the oil retaining pipe is connected to a second air duct, and the second air duct is connected to a negative pressure fan through a pipeline.

[0024] By adopting the above technical solution, the cold heading machine body can utilize the second air duct with a negative pressure fan, and the air flow formed by the fan blades flows through the middle of the lighter grinding wheel and its own weight, blowing out the remaining metal debris and flowing it into the waste box through the second air duct, thereby improving the cleanliness of the lighter grinding wheel surface and ensuring the processing quality. At the same time, under the overall technical solution, it can adapt to increasing the forward and reverse wind force of the fan, thereby improving the cleaning speed and processing efficiency of the lighter grinding wheel.

[0025] Optionally, a second partition is connected to the collection box, which divides the collection box into a storage chamber and a cleaning chamber. A screening motor is connected to the storage chamber, and the driving rod of the screening motor passes through the second partition and is connected to the buffer block. The surface of the buffer block is provided with an arc surface.

[0026] By adopting the above technical solution, the collection box can be divided into a storage chamber and a cleaning chamber. The screening motor is used to control the rotation of the buffer block so that the lighter grinding wheel on the buffer block with an arc surface can slide down quickly due to centrifugal force. Combined with the different friction forces between the lighter grinding wheels with different cleanliness and the buffer block, the lighter grinding wheels with cleanliness that meet the standards can slide down to the storage chamber, and the lighter grinding wheels with unsatisfactory cleanliness can fall into the cleaning chamber for cleaning.

[0027] Optionally, a collecting block is connected to the cleaning chamber, the diameter of the collecting block is larger than the diameter of the buffer block, an arc-shaped groove is opened in the collecting block, the arc-shaped groove is connected to the storage chamber, and the cavity between the inner wall of the cleaning chamber and the collecting block is filled with cleaning liquid.

[0028] By adopting the above technical solution, the lighter grinding wheels that meet the cleanliness standards and fall from the buffer block can be collected into the storage chamber through the arc groove; for the lighter grinding wheels that do not meet the cleanliness standards, they are dropped into the cleaning liquid for further cleaning.

[0029] Optionally, a storage box is slidably connected to the storage chamber.

[0030] By adopting the above technical solution, the storage box can automatically collect the cleaned and qualified lighter grinding wheels, which is convenient for subsequent processing. The storage box can be slidably connected to the storage chamber, making it easy to remove and replace the storage box to continuously and effectively collect lighter grinding wheels.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The forward and reverse rotating blower absorbs the lighter grinding wheel through the first air duct, sucking the metal debris remaining on the inner wall of the lighter grinding wheel and the oil stains attached to the metal debris into the waste bin. When the lighter grinding wheel collides with the pressure sensor, it switches to the blowing mode and blows the lighter grinding wheel out of the first air duct, realizing automatic cleaning of the stains on the inner wall of the lighter grinding wheel and improving work efficiency.

[0033] 2. When the lighter grinding wheel slides in the spiral pipe, the spiral plate contacts the surface of the lighter grinding wheel to form friction, causing the lighter grinding wheel to rotate. The oil stains attached to the surface of the lighter grinding wheel can be thrown out and recovered under the action of centrifugal force, effectively cleaning the lighter grinding wheel surface. After production, the lighter grinding wheel falls into the collection box through the buffer block, which can reduce damage to the lighter grinding wheel surface.

[0034] 3.

[0047] The following is combined with Figure 1 -Attached Figure 11, further details of this application are given.

[0048] Example 1:

[0049] A cold heading machine for lighter grinding wheels, Figure 1 The cold heading machine body 1 includes a discharge port and a cleaning device disposed below the discharge port of the cold heading machine body 1. The cleaning device is used to clean oil stains and metal debris from the surface of the lighter grinding wheel produced by the cold heading machine body 1. The lighter grinding wheel is a hollow cylinder.

[0050] Reference Figure 1 、 Figure 2 The cold heading machine body 1 is fixedly connected to a discharge pipe 2 at the discharge port. The cleaning device includes a guide rail 3 fixedly connected to the discharge pipe 2. The guide rail 3 includes a receiving section 301, a raised section 302, and a feeding section 303. The receiving section 301 is arc-shaped, with one end fixedly connected to the inner wall of the discharge pipe 2 and the other end smoothly transitioning to the raised section 302. The raised section 302 has one end smoothly connected to the receiving section 301 and then arc-shapedly protrudes toward the end of the discharge pipe 2, forming a deceleration area. The other end smoothly transitions to the feeding section 303. The feeding section 303 extends horizontally away from the raised section 302.

[0051] When the lighter grinding wheel is unloaded from the discharge port, it first slides along the receiving section 301 and its posture gradually transitions from vertical to horizontal. When sliding to the raised section 302, the sliding speed of the lighter grinding wheel gradually decreases. After the lighter grinding wheel climbs up the raised section 302 and is between the raised section 302 and the feeding section 303, the lighter grinding wheel stops sliding.

[0052] Reference Figure 1 、 Figure 2 、 Figure 3 A forward and reverse fan 4 is installed on one side of the cold heading machine body 1, wherein the forward and reverse fan 4 is in a negative pressure suction state when turned on. The forward and reverse fan 4 is connected to the first air duct 5 through a pipeline, and the first air duct 5 is located above the raised section 302 of the guide rail 3. A plug-in slot 6 is provided at the end of the first air duct 5 facing away from the feeding section 303 of the guide rail 3, and an elastic surface 10 is fixedly connected to the arc-shaped inner wall of the plug-in slot 6, wherein the elastic surface 10 is arranged in a trumpet shape, and its opening is consistent with the opening of the plug-in slot 6. Moreover, a pressure sensing plate 7 is fixedly connected to the bottom of the plug-in slot 6, and the pressure sensing plate 7 is electrically connected to the forward and reverse fan 4. In addition, a drive motor 8 is installed on one side of the cold heading machine body 1, and the drive rod of the drive motor 8 is fixedly connected to the limiting rod 9, wherein the limiting rod 9 passes through and is inserted into the discharge pipe 2, and at the same time, the drive motor 8 is electrically connected to the pressure sensing plate 7.

[0053] When the lighter grinding wheel is between the raised section 302 and the feeding section 303, the forward and reverse blower 4 absorbs the lighter grinding wheel through the first air duct 5, causing the lighter grinding wheel to slide toward the bottom of the slot 6. During the sliding process of the lighter grinding wheel, the elastic surface 10 continuously presses against the lighter grinding wheel, thereby slowing the sliding speed of the lighter grinding wheel and increasing the time the lighter grinding wheel is absorbed. In addition, the surface of the forward and reverse blower 4 is connected to the waste bin 26 via an electric valve, and the electric valve is electrically connected to the pressure sensor 7. When the forward and reverse blower 4 absorbs the lighter grinding wheel, it can suck the metal debris remaining on the inner wall of the lighter grinding wheel and the oil stains attached to the metal debris into the waste bin 26.

[0054] When the lighter grinding wheel collides with the pressure sensing plate 7, the forward and reverse blower 4 is converted to the blowing mode, thereby blowing the lighter grinding wheel out of the first air duct 5, causing it to slide on the feeding section 303 of the guide rail 3; the driving motor 8 controls the limiting rod 9 to slide away from the cold heading machine body 1, so that a newly produced lighter grinding wheel of the cold heading machine body 1 is unloaded, and the frequency of lighter grinding wheel production is consistent with the frequency of sliding of the limiting rod 9; the electric valve is closed to prevent the waste in the waste box 26 from being blown out.

[0055] Reference Figure 2 、 Figure 4 、 Figure 5 The feeding section 303 of the guide rail 3 is fixedly connected to the guide tube 11, and the end of the wire tube is fixedly connected to the oil blocking tube 12. A spiral pipe is inserted in the oil blocking tube 12, and the diameter of the inner wall of the spiral pipe is consistent with the diameter of the outer wall of the lighter grinding wheel. In addition, the spiral pipe is composed of four spiral plates 13, and a gap is provided between two adjacent spiral plates 13.

[0056] Reference Figure 4 、 Figure 6 The inner wall of the bottom of the oil retaining tube 12 is fixedly connected to a first partition 14. A through hole corresponding to the diameter of the lighter grinding wheel is opened in the middle of the first partition 14, and the spiral plate 13 is inserted into the first partition 14. An oil storage ring 15 is axially sleeved on the surface of the oil retaining tube 12 above the first partition 14. The oil storage ring 15 is connected to the oil retaining tube 12 and is connected to the oil storage tank 16 through a pipeline.

[0057] When the lighter grinding wheel slides into the spiral pipe along the feed section 303 of the guide rail 3 and the guide pipe 11 under the blowing drive of the forward and reverse blower 4, the surface of the lighter grinding wheel rubs against the inner wall of the spiral plate 13, and the lighter grinding wheel falls downward under the action of its own weight, thereby causing the lighter grinding wheel to rotate in the spiral pipe. The oil stains attached to the surface of the lighter grinding wheel are thrown out by the centrifugal force and adhere to the inner wall of the oil baffle 12. The oil stains attached to the inner wall of the oil baffle gradually flow onto the first partition 14 under the action of gravity, and then flow into the oil storage ring 15 through the first partition 14, and finally flow into the oil storage tank 16 through the pipeline for recovery.

[0058] Reference Figure 5 The bottom plate of the oil retaining tube 12 is installed with a collection box 17, and a buffer block 18 is fixedly connected to the collection box 17. When the lighter grinding wheel falls from the oil retaining tube 12, it collides with the buffer block 18 to reduce damage to the surface of the lighter grinding wheel.

[0059] The implementation principle of the embodiment of the present application is as follows: by using the forward and reverse rotating blower 4 in conjunction with the first air duct 5, the metal debris remaining inside the lighter grinding wheel is first cleaned, thereby effectively reducing the damage caused by the lighter grinding wheel to the surface of the spiral plate 13. Moreover, by using the first air duct 5 to absorb the lighter grinding wheel and make it contact with the pressure sensing plate 7, the unloading of the cold heading machine body 1 is controlled, which can effectively avoid the accumulation of the lighter grinding wheel on the guide rail 3 and ensure that the metal debris on the inner wall of the lighter grinding wheel is completely cleaned. In addition, when the lighter grinding wheel is under the action of the thrust generated by the weight of the spiral pipe and the air blowing of the forward and reverse rotating blower 4, the spiral plate 13 of the spiral pipe contacts the lighter grinding wheel, and the friction force forces the lighter grinding wheel to rotate, thereby causing the oil stains on the surface of the lighter grinding wheel to be thrown out under the action of centrifugal force.

[0060] Example 2:

[0061] A cold heading machine for lighter grinding wheels, Figure 7 、 Figure 8 、 Figure 9 The difference between it and Example 1 is that the end of the spiral plate 13 away from the guide tube 11 is integrally connected to a vertically arranged transition rod 19. In addition, the first partition 14 is trumpet-shaped, and its trumpet opening is opened in the direction away from the guide tube 11, and the first partition 14 is divided into a rotating part 1401 and a fixed part 1402, and the rotating part 1401 is rotatably connected to the fixed part 1402, wherein the transition rod 19 is embedded in the rotating part 1401 of the first partition 14. The end of the transition rod 19 away from the spiral plate 13 is first bent close to the inner wall of the oil retaining tube 12, and then bent away from the inner wall of the oil retaining tube 12 to form a fan blade 20, and the spiral extension direction of the fan blade 20 is opposite to the spiral extension direction of the spiral plate 13. The end of the fan blade 20 is fixedly connected to a drive ring 21, and one end of the drive ring 21 extends out of the oil retaining tube 12. In addition, the other end of the drive ring 21 is fixedly connected to a plurality of limit rods, and one end of the limit tube is fixedly connected to the transition rod 19, so as to avoid contact between the lighter grinding wheel and the fan blade 20.

[0062] The portion of the drive ring 21 outside the oil retaining tube 12 is connected to a rotary motor 22 via a leather hose. Furthermore, a rotary shaft 23 is fixedly connected to the inner wall of the upper end of the oil retaining tube 12, and this shaft 23 is fixedly connected to the end of the spiral plate 13. Furthermore, a second air duct 24 is fixedly connected to the upper side wall of the oil retaining tube 12. This second air duct 24 is connected to a negative pressure blower 25 via a pipe, and this negative pressure blower 25 is also connected to a waste bin 26 via a pipe.

[0063] The operating principle of the embodiment of the present application is as follows: When the rotating motor 22 drives the drive ring 21 via a belt, the fan blades 20 rotate to generate airflow, which flows toward the inner wall of the spiral duct. At the same time, part of the airflow flows along the trumpet-shaped first baffle 14, thereby converging and concentrating the airflow, thereby increasing the flow rate of the airflow into the spiral duct. At the same time, the spiral plate 13 rotates to generate airflow toward the inner wall of the oil retaining tube 12 and the upper surface of the first baffle 14. When the lighter grinding wheel slides into the spiral duct under the first air duct 5 and under its own weight, the lighter grinding wheel rotates under the friction of the spiral plate 13. The rotation of the spiral plate 13 drives the lighter grinding wheel to rotate further, thereby increasing the rotation speed of the lighter grinding wheel. At the same time, the airflow generated by the fan blades 20 slows the falling speed of the lighter grinding wheel, thereby increasing the residence time of the lighter grinding wheel in the spiral duct and improving the cleanliness of the lighter grinding wheel surface.

[0064] In addition, the airflow formed by the fan blades 20 flows through the center of the lighter grinding wheel and, in conjunction with the weight of the lighter grinding wheel, blows out the remaining metal debris. The blown metal debris flows into the waste bin 26 through the second air duct 24. At the same time, based on the solution of Example 2, the wind force of the forward and reverse rotating blower 4 can be adaptively increased to increase the cleaning speed of the lighter grinding wheel, thereby improving processing efficiency.

[0065] Example 3:

[0066] A cold heading machine for lighter grinding wheels, Figure 10 、 Figure 11 The difference between this embodiment and Example 2 is that a second partition plate 28 is fixedly connected to the collection box 17, and the second partition plate 28 separates the collection box 17 into a storage chamber 1701 and a cleaning chamber 1702. A collection block 29 is fixedly connected to the cleaning chamber 1702, and an arc-shaped groove 30 is formed in the collection block 29. A through hole communicating with the storage chamber 1701 is formed at the bottom of the arc-shaped groove 30. In addition, the cavity between the outer wall of the collection block 29 and the inner wall of the cleaning chamber 1702 is filled with cleaning liquid 31, and an infrared sensor 32 is fixedly connected to the inner wall of the cleaning chamber 1702, and the infrared sensor 32 is connected to an alarm.

[0067] A screening motor 33 is fixedly connected to the inner wall of the storage chamber 1701. The drive rod of the screening motor 33 passes through a through hole and extends into the cleaning chamber 1702. The end of the drive rod of the screening motor 33 is fixedly connected to the buffer block 18. At the same time, the side of the buffer block 18 away from the screening motor 33 is provided with an arc surface. In addition, the outer cover of the screening crane is provided with a protective cover 34, which is fixedly connected to the inner wall of the storage chamber 1701. The storage box 27 is slidably connected to the storage chamber 1701, and the lighter grinding wheels after production are collected through the storage box 27.

[0068] The implementation principle of the embodiment of the present application is: when the lighter grinding wheel is cleaned and falls onto the buffer block 18, the buffer block 18 rotates under the drive of the screening motor 33, so that the lighter grinding wheel located on the buffer block 18 rotates synchronously, so that the lighter grinding wheel on the curved surface of the buffer block 18 will slide outward under the action of centrifugal force.

[0069] When the oil stain cleanliness on the surface of the lighter grinding wheel meets the standard, the friction between the lighter grinding wheel and the buffer block 18 is relatively large, so that after the lighter grinding wheel falls from the buffer block 18, it can fall into the collecting block 29 and enter the storage box 27 of the storage chamber 1701 along the arc groove 30 and the through hole.

[0070] When the oil stains on the surface of the lighter grinding wheel are not clean enough, the friction between the lighter grinding wheel and the buffer block 18 is small, so that after the lighter grinding wheel falls from the buffer block 18, it can fall into the cleaning fluid 31 to further clean the surface of the lighter grinding wheel. When too much oil stains accumulate on the lighter grinding wheel at the cleaning fluid 31 and are irradiated by the infrared sensor 32, the infrared sensor 32 triggers the alarm to remind the staff to inspect the equipment.

[0071] The cleaning and screening process of lighter grinding wheels can be further optimized, and the cleaning standards and those that do not are automatically distinguished, thereby ensuring the final quality of lighter grinding wheels and greatly improving production efficiency and product qualification rate. This is another improvement and innovation of existing technologies and can better meet the refined requirements of actual production.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
