Description

Technical Field

[0001] This invention belongs to the field of heat treatment technology for bearing parts, specifically a stamping device for heat treatment protection of asbestos pads for bearing parts. Background Technology

[0002] Typical defects in heat treatment quenching include deformation, cracking, insufficient hardness, and oxidation / decarburization, among which quenching cracking is the most serious and irreparable. The main causes of cracking include excessively rapid cooling, stress concentration, overheating, failure to temper promptly after quenching, and material defects. Parts with complex shapes and multiple steps, and relatively thin dimensions (approximately 2mm-3mm), are prone to stress concentration at these transition points, leading to cracking. Protecting these areas and slowing down the cooling rate can prevent cracking caused by excessively rapid cooling under thermal and structural stress.

[0003] Without the aid of a stamping device, asbestos was manually bound to protect the parts. The specific method involved the operator cutting 20mm x 100mm rectangular strips from a whole sheet of asbestos mat, wrapping them around the parts requiring protection, and securing them with wire. This method was cumbersome, requiring 3-4 people to bind one batch of parts simultaneously, resulting in very low efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is: a stamping device for heat treatment protection of asbestos pads for bearing parts, comprising: a first die and a layering component, wherein a circular cutting edge is provided at the bottom of the first die;

[0005] The first die is internally fitted with a stamping component;

[0006] The stamping component includes a connecting rod disposed above the inner wall of the first die and a second die disposed at the bottom end of the connecting rod;

[0007] The bottom of the second die has a circular cutting edge, and the diameter of the cutting edge of the second die is smaller than the diameter of the cutting edge of the first die.

[0008] The outer ring of the bottom of the second die has a groove, and the first die is sleeved on the outside of the second die. The groove creates a diameter difference between the cutting edge of the second die and the cutting edge of the first die, and this diameter difference is the required asbestos gasket ring width.

[0009] Furthermore, it also includes a moving mechanism disposed below the layered component, the moving mechanism surrounding the outside of the first die;

[0010] The layered component is fitted onto the end of the stamping component away from the cutting edge.

[0011] Furthermore, the stamping component also includes a second cleaning ring and an elastic ring;

[0012] The second cleaning ring is fitted inside the end of the second die near the cutting edge;

[0013] The elastic ring is fitted on the inner wall of the first die near the cutting edge and fits against the outer wall of the second die.

[0014] Furthermore, the stamping component also includes a second punch and an extrusion block;

[0015] The second punch block is installed above the second punch die, and the outer wall of the second punch block is fitted with the inner wall of the layered component;

[0016] The extrusion blocks are evenly arranged in the inner ring of the first die. The other end of the extrusion block is connected to the outer ring of the elastic ring. The elastic ring is in contact with the outer wall of the second die by the force provided by the extrusion block away from the first die. The extrusion block is made of elastic material, so that the bottom of the elastic ring is in a raised state. The other end of the extrusion block is connected to the outer ring of the elastic ring. The elastic ring is in contact with the outer wall of the second die by the force provided by the extrusion block away from the first die.

[0017] Furthermore, the layered component includes a mounting plate, a locking block, and a support column;

[0018] The mounting plate is disposed at the end of the first punch away from the cutting edge, and the inner wall of the mounting plate is sleeved with the outer wall of the second punch.

[0019] The support columns are symmetrically arranged on both sides of the mounting plate, and one end of the support column is rotatably connected to the inner wall of the mounting plate.

[0020] The locking blocks are symmetrically arranged at both ends of the top of the mounting plate. The locking blocks are made of elastic material and vertically lock the support column onto the mounting plate.

[0021] Furthermore, the layered component also includes a first punch block, a limiting block, and a telescopic column;

[0022] The first punch is installed at the end of the support column away from the mounting plate. The first punch is semi-circular and has a groove near the center of the top.

[0023] The limiting block is placed inside the groove;

[0024] The telescopic columns are evenly arranged around the inner circular surface of the mounting plate.

[0025] Furthermore, the moving mechanism includes a base, a frame, a support rod, and rollers;

[0026] The frame rod is mounted on two adjacent bases, and the frame rod is rotatably connected to the bases;

[0027] The roller is limited by a support rod, so that the roller rolls on the frame rod with the frame rod as the axis.

[0028] The support rods are symmetrically arranged on both sides of the roller. One end of the support rod is sleeved on the outside of the frame rod, and the other end of the support rod is rotatably connected to the inner wall of the base.

[0029] Furthermore, the moving mechanism also includes a telescopic assembly, a fixing rod, an inflation tube, and a first cleaning ring;

[0030] The telescopic components are evenly arranged below the mounting plate, and the telescopic components surround the outside of the first punch.

[0031] The first cleaning ring is installed on the outer wall of the telescopic assembly by a fixing rod, and the inner wall of the first cleaning ring is sleeved with the outer wall of the first punch.

[0032] The inflation tube is installed on the outer wall of two adjacent telescopic components.

[0033] Furthermore, the telescopic assembly includes a sleeve, a movable rod, and a resilient column;

[0034] The sleeve is mounted on the base, and an air hole is provided on the lower part of the sleeve near the air pipe;

[0035] The movable rod is sleeved on the inner wall of the sleeve, and the lower part of the movable rod is connected to the elastic column. The elastic column is installed at the bottom of the inner wall of the sleeve, and the length of the elastic column is greater than the distance between the air hole and the bottom of the inner wall of the sleeve.

[0036] The beneficial effects of this invention are as follows:

[0037] 1. This invention, by setting up a stamping component, allows the elastic ring and the second cleaning ring to clean the cutting edge of the second die during the up-and-down movement of the second die, reducing asbestos debris adhering to the bottom of the second die. During the movement of the first die by the moving mechanism, the first cleaning ring moves up and down relative to the first die, thus cleaning the outer wall of the first die. This reduces contact between the worker and the cutting edge, avoiding danger. Stamping the asbestos pad with the stamping component directly produces a ring-shaped protective asbestos pad, which can be directly fitted onto the part without the need for wire binding, simplifying the operation and improving work efficiency.

[0038] 2. By setting up layered components, when the first die is stamping, the two pillars bypass the locking block and are locked in the vertical direction, so that the first punch block is merged into a circle and locked by the limiting block. At this time, tapping the first punch block can help the first die to stamp quickly. Then, when stamping the second die, it is only necessary to remove the limiting block and open the first punch block. The operation is relatively simple and convenient, and it can be completed in one device, avoiding frequent changes that may cause worker injury during the change process.

[0039] 3. This invention, through the setting of a moving mechanism, allows the first die to contact the asbestos pad under the drive of the telescopic component. By striking the first punch block, the first disc can be stamped. Subsequently, the telescopic component lifts the first die upward away from the asbestos pad, and the layering component lowers the second die to stamp the second disc, forming an alternation of the two dies. During this movement, the first cleaning ring cleans the cutting edge of the first die. Then, the frame is bent back to its original position and moved to the next position, enabling the entire equipment to move quickly, reducing the workload of workers, and preventing workers from contacting the cutting edge. The telescopic component allows for adjustable up and down movement of the first die, reducing contact between the cutting edge and the hard surface at the bottom of the asbestos pad, thus protecting the first die.

[0040] 4. This invention incorporates a telescopic component. An inflation device connected to the inflation tube inflates the inside of the sleeve, causing the moving rod to move upward and lift the first punch. This prevents the first punch from directly striking the asbestos pad during the frame's transformation, thus avoiding initial stamping defects. After the base is stably placed on the asbestos pad, inflation is gradually stopped, allowing the first punch to descend naturally under gravity. The elastic rod cushions the first punch, preventing the blade from striking downwards directly. After the first punch completes its stamping, inflation resumes, lifting the first punch and protecting its blade from the impact of the second punch's pressure. This prevents the first punch from impacting the bottom of the asbestos pad again, reducing wear on the first punch. Attached Figure Description

Detailed Implementation

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0051] Example 1, please refer to Figures 1-8 The present invention provides a technical solution: a stamping device for heat treatment protection of asbestos pads for bearing parts is described below.

[0052] Includes: a first die 1 and a layered component 2, wherein the bottom of the first die 1 has a circular cutting edge;

[0053] The first die 1 is internally fitted with a stamping component 4;

[0054] It also includes a moving mechanism 3 disposed below the layered component 2, the moving mechanism 3 surrounding the outside of the first punch 1;

[0055] The layered component 2 is fitted onto the end of the stamping component 4 that is away from the cutting edge.

[0056] To use, lay the entire asbestos pad flat on a platform and draw parallel lines spaced 50mm apart on it. First, place the first die 1 along the drawn lines on the asbestos pad, starting from one end. After moving the moving mechanism 3 to the appropriate position, place the first die 1 on the asbestos pad and strike the layered component 2 with a hammer. This will punch out a circular asbestos pad. Then, disassemble the layered component 2, keeping the first die 1 stationary and ensuring the asbestos pad is not moved. Place the stamping component 4 on the asbestos pad and strike it again with a hammer to obtain a ring-shaped asbestos pad. After stamping at one position, lift the entire device upwards, allowing the rollers at the bottom of the moving mechanism 3 to move the device to the next position for stamping again. Repeat this process until the ring-shaped asbestos pad is placed on the bearing or similar parts that require protection, thus completing the protection of the parts.

[0057] The stamping component 4 includes a connecting rod 401 disposed above the inner wall of the first die 1 and a second die 402 disposed at the bottom end of the connecting rod 401;

[0058] The bottom of the second die 402 has a circular cutting edge, and the diameter of the cutting edge of the second die 402 is smaller than the diameter of the cutting edge of the first die 1.

[0059] The bottom outer ring of the second die 402 has a groove. The first die 1 is sleeved on the outside of the second die 402. The groove creates a diameter difference between the cutting edge of the second die 402 and the cutting edge of the first die 1. This diameter difference is the required asbestos gasket ring width.

[0060] The stamping component 4 also includes a second cleaning ring 403 and an elastic ring 404;

[0061] The second cleaning ring 403 is sleeved on the inner side near the cutting edge of the second die 402, and the second cleaning ring 403 is used to clean the inner side of the second die 402.

[0062] The elastic ring 404 is sleeved on the inner wall of the first die 1 near the cutting edge and fits against the outer wall of the second die 402. The elastic ring 404 is used to clean the outer side of the second die 402.

[0063] The stamping component 4 also includes a second punch 405 and an extrusion block 406;

[0064] The second punch block 405 is installed above the second punch die 402, and the outer wall of the second punch block 405 is sleeved with the inner wall of the layered component 2.

[0065] The extrusion blocks 406 are evenly arranged in the inner ring of the first die 1. The extrusion blocks 406 are made of elastic material, so that the bottom of the elastic ring 404 is in a raised state. The other end of the extrusion blocks 406 is connected to the outer ring of the elastic ring 404. The elastic ring 404 is in contact with the outer wall of the second die 402 by the force provided by the extrusion blocks 406 that moves away from the first die 1.

[0066] After the moving mechanism 3 moves the stamping component 4 to the corresponding position on the asbestos pad, the second die 402 and the first die 1 are placed on the asbestos pad. Initially, the layering component 2 moves the second die 402 away from the asbestos pad. At this time, the blade of the first die 1 is in contact with the asbestos pad, and the layering component 2 is in a locked state. The layering component 2 is struck with a hammer to stamp a circular piece off the asbestos pad. Then, the layering component 2 lowers the second die 402 and opens the layering component 2. By striking the second punch block 405 with a hammer, the second die 402 stamps out the small circle in the middle of the circular piece, thus completing the required asbestos pad ring. During the up-and-down movement of the die 402, the elastic ring 404 and the second cleaning ring 403 clean the cutting edge of the second die 402, reducing the asbestos debris adhering to the bottom of the second die 402. As the moving mechanism 3 moves the first die 1 left and right and lowers it, the first cleaning ring 308 moves up and down relative to the first die 1, thereby completing the cleaning of the outer wall of the first die 1, reducing contact between the operator and the cutting edge, and avoiding danger. The stamping part 4 can be used to stamp on the asbestos pad to directly obtain a ring-shaped protective asbestos pad. The asbestos pad can be directly put on the part without the need for wire binding, simplifying the operation steps and improving work efficiency.

[0067] Layered component 2 includes mounting plate 201, locking block 202, and support column 203;

[0068] Mounting plate 201 is located at the end of the first punch 1 away from the cutting edge, and the inner wall of mounting plate 201 is sleeved with the outer wall of the second punch 405.

[0069] The support columns 203 are symmetrically arranged on both sides of the mounting plate 201, and one end of the support column 203 is rotatably connected to the inner wall of the mounting plate 201.

[0070] The locking blocks 202 are symmetrically arranged at both ends of the top of the mounting plate 201. The locking blocks 202 are made of elastic material. The locking blocks 202 vertically lock the support column 203 onto the mounting plate 201. The shape of the locking blocks 202 is wide at both ends and narrow in the middle, so that the two first punch blocks 204 are locked.

[0071] The layered component 2 also includes a first punch block 204, a limiting block 205, and a telescopic column 206;

[0072] The first punch 204 is installed on the end of the support column 203 away from the mounting plate 201. The first punch 204 is semi-circular and has a groove near the center of the top.

[0073] The limiting block 205 is placed in the groove;

[0074] The telescopic columns 206 are evenly arranged around the inner circular surface of the mounting plate 201.

[0075] When the support column 203 is vertical, it splices the two first punch blocks 204 into one circular plate, which is fixed by the locking block 202.

[0076] When the first die 1 is being stamped, the two pillars 203 bypass the locking block 202 and are locked in the vertical direction, causing the first punch block 204 to merge into a circle and be locked by the limiting block 205. At this time, striking the first punch block 204 can help the first die 1 to stamp quickly. Then, when the second die 402 is being stamped, it is only necessary to remove the limiting block 205 and open the first punch block 204. The operation is relatively simple and convenient, and can be completed in one device, avoiding frequent changes that may cause workers to be injured during the change process.

[0077] The moving mechanism 3 includes a base 301, a frame rod 302, a support rod 303, and a roller 304;

[0078] The support rod 302 is installed on two adjacent bases 301, and the support rod 302 is rotatably connected to the base 301;

[0079] The roller 304 is limited by the support rod 303, so that the roller 304 rolls on the frame rod 302 with the frame rod 302 as the axis;

[0080] Support rods 303 are symmetrically arranged on both sides of roller 304. One end of the support rod 303 is sleeved on the outside of the frame rod 302, and the other end of the support rod 303 is rotatably connected to the inner wall of the base 301.

[0081] The moving mechanism 3 also includes a telescopic assembly 305, a fixing rod 306, an inflation tube 307, and a first cleaning ring 308;

[0082] The telescopic components 305 are evenly arranged below the mounting plate 201, and the telescopic components 305 surround the outside of the first punch 1;

[0083] The first cleaning ring 308 is installed on the outer wall of the telescopic assembly 305 via the fixing rod 306, and the inner wall of the first cleaning ring 308 is sleeved with the outer wall of the first punch 1.

[0084] The inflation tube 307 is installed on the outer wall of two adjacent telescopic components 305.

[0085] In use, first rotate the support rod 302 90 degrees around the base 301, so that the limiting rod is downward, allowing the roller 304 on the support rod 302 to move freely on the asbestos pad. When it moves to the appropriate position, pry the support rod 302 open to both sides, so that the support rod 302 is separated from the asbestos pad, and the base 301 contacts the asbestos pad. At this time, the first punch 1, driven by the telescopic component 305, contacts the asbestos pad. By striking the first punch block 204, the first round piece can be punched. Then, the telescopic component 305 lifts the first punch 1 upward away from the asbestos pad. The layered component 2 lowers the second die 402 to stamp the second disc, forming an alternation of the two dies. During this movement, the first cleaning ring 308 cleans the blade of the first die 1. Then, the support rod 302 is pushed back to its original position and moved to the next position, enabling the entire equipment to move quickly, reducing the workload of workers and preventing workers from contacting the blade. The telescopic component 305 allows the first die 1 to move up and down in an adjustable manner, reducing the contact between the blade and the hard surface of the asbestos pad at the bottom, thus protecting the first die 1.

[0086] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the telescopic component 305 includes a sleeve 3051, a moving rod 3052 and an elastic column 3053;

[0087] The sleeve 3051 is mounted on the base 301, and an air hole 3054 is provided on the lower part of the sleeve 3051 near the air pipe.

[0088] The movable rod 3052 is sleeved on the inner wall of the sleeve 3051. The lower part of the movable rod 3052 is connected to the elastic column 3053. The elastic column 3053 is installed at the bottom of the inner wall of the sleeve 3051. The length of the elastic column 3053 is greater than the distance between the air hole 3054 and the bottom of the inner wall of the sleeve 3051.

[0089] After the support rod 302 is pried open, when the base 301 contacts the top of the asbestos pad, the inflation device connected to the inflation pipe 307 inflates the inside of the sleeve 3051, causing the moving rod 3052 to move upward, thereby lifting the first punch 1. This prevents the first punch 1 from directly hitting the asbestos pad during the transformation of the support rod 302, which could cause the initial stamping to result in a defective product. After the base 301 is placed stably on the asbestos pad, the inflation is gradually stopped, allowing the first punch 1 to descend naturally by gravity. The elastic rod cushions the first punch 1, preventing the blade from hitting directly downward. After the first punch 1 completes the stamping, it is inflated again to lift the first punch 1, protecting the blade from being affected by the stamping force of the second punch 402, so that it can impact the bottom of the asbestos pad again, reducing the wear of the first punch 1.

[0090] The specific workflow is as follows:

[0091] When in use, the whole asbestos pad is laid flat on the platform. Parallel lines with a spacing of 50mm are drawn on the asbestos pad. First, the first punch 1 is placed in the parallel lines drawn on the asbestos pad from one end. The support rod 302 is rotated 90 degrees around the base 301 so that the limit rod is downward, so that the roller 304 on the support rod 302 can move freely on the asbestos pad. When it moves to the appropriate position, the support rod 302 is pried open to both sides so that the support rod 302 is separated from the asbestos pad and the base 301 contacts the asbestos pad. At this time, the first punch 1 contacts the asbestos pad under the drive of the telescopic component 305.

[0092] Initially, the layering component 2 moves the second punch 402 away from the asbestos pad. At this time, the blade of the first punch 1 is in contact with the asbestos pad, and the layering component 2 is in a locked state. The layering component 2 is struck with a hammer to make a round piece punched off the asbestos pad. Then the telescopic component 305 lifts the first punch 1 upward away from the asbestos pad, and the layering component 2 lowers the second punch 402 to punch the second round piece, forming an alternation of the two punches. During this movement, the blade of the first punch 1 is cleaned by the first cleaning ring 308. Then the support rod 302 is turned back to its original position and moved to the next position.

[0093] When the first die 1 is stamping, the two pillars 203 bypass the locking block 202 and are locked in the vertical direction, so that the first punch 204 is merged into a circle and locked by the limiting block 205. At this time, tapping the first punch 204 can help the first die 1 to stamp quickly. Then, when the second die 402 is stamping, it is only necessary to remove the limiting block 205 and open the first punch 204. Finally, the annular asbestos pad is put on the bearing part that needs protection to complete the protection of the part.

[0094] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
