Description

Technical Field

[0001] The invention relates to the technical field of presses, and more particularly to a pressure forming device for producing a tooth spline sleeve. Background Art

[0002] A spline sleeve is a mechanical part used to connect a shaft to other rotating parts (such as gears, pulleys or couplings) to transmit torque. It consists of an outer ring gear and an inner ring gear, similar to the structure of a spline. A spline is a structure with multiple protrusions (teeth). The inner teeth of the spline sleeve match the splines on the shaft, and the outer teeth connect to the inner splines of the mating part. There are many different types of equipment to produce spline sleeves, covering multiple manufacturing processes such as stamping, cold extrusion, precision machining, etc. Each type of equipment has its specific application.

[0003] Among them, cold extrusion, hot extrusion, stamping and other methods are usually formed by a press. The process of processing spline sleeves by a press has the advantages of high efficiency, batch production and low cost in the production process. It is particularly suitable for mass production of spline sleeves with medium precision and regular shapes.

[0004] Each time the press machine processes the spline sleeve, it needs to apply lubricant manually. Usually, the lubricant is applied to the mold manually by dipping a sponge. Since the mold surface is distributed with teeth for forming the inner wall of the spline sleeve, it is difficult to evenly apply it to the gaps between the teeth when applying it manually. In addition, only one side of the mold faces the worker, and the lubricant application on the other side of the mold depends entirely on manual blind application. It is difficult to ensure that the lubricant fully covers the mold surface, which reduces the lubrication effect. Therefore, it is necessary to propose a pressure forming device for producing spline sleeves to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] For example, see Figure 1-Figure 11 As shown, the present invention discloses a pressure forming device for producing a tooth spline sleeve, comprising a main body mechanism 1, the main body mechanism 1 comprises a support platform 11, and a base 12 and a box body 15 are installed on the top surface of the support platform 11;

[0040] A moving mechanism 2 is installed inside the box 15. The moving mechanism 2 includes a hydraulic push rod 21 installed inside the box 15. A support arm 22 is installed at the output end of the hydraulic push rod 21. A pressure plate 23 is installed at the end of the support arm 22. A mold 25 is installed on the bottom surface of the pressure plate 23.

[0041] A stabilizing mechanism 3 is mounted on the base 12, and the stabilizing mechanism 3 includes columns 31 mounted in an array on the top surface of the base 12;

[0042] A feeding mechanism 4 is installed on the column 31, and the feeding mechanism 4 includes a shell 41 slidably connected to the column 31, a storage tank 42 and a pump body 43 are installed on the top surface of one end of the shell 41, and the pump body 43 is connected to the bottom of the storage tank 42, and a plurality of rotating blocks 45 are symmetrically installed on the top surface of the other end of the shell 41, a nozzle 46 is installed on one side of the rotating block 45, and the pump body 43 is connected to the other side of the rotating block 45 through a pipe 44;

[0043] The shell 41 is provided with a smearing mechanism 6 , which includes a first slider 61 slidably connected to the other end of the shell 41 , and a brush head 62 is installed on the first slider 61 .

[0044] The base 12 is provided with a plurality of columns 31 in a circumferential array, which are sleeved on the columns 31 through the side ears 24, so as to better ensure the vertical lifting of the pressure plate 23, so that the mold 25 is accurately inserted into the molding hole 14, which helps to improve the production quality of the product. The housing 41 is suspended on the column 31 through the support of the first spring 32. In the initial stage, the shell 41 is suspended, and the mold 25 at the bottom of the pressure plate 23 is higher than the shell 41. First, the storage tank 42 is filled with lubricant for lubricating the mold 25. The lubricant is pumped into the rotating block 45 through the pump body 43, and then sprayed onto the brush head 62 from the nozzle 46; then the hydraulic push rod 21 is started, and the hydraulic push rod 21 drives the pressure plate 23 to descend through the support arm 22. The pressure plate 23 drives the side ear 24 to slide on the column 31, and at the same time drives the mold 25 to descend. The mold 25 passes through the brush head 62, and the brush head 62 smears the lubricant on the surface of the mold 25 to achieve the purpose of automatic smearing. A plurality of brush heads 62 are arranged around the mold 25, which can ensure that the surface of the mold 25 is coated with lubricant 360 degrees without dead angles.

[0045] Example 2: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 11 The main body mechanism 1 also includes a mold table 13 installed on the top surface of the base 12, the top surface of the mold table 13 is provided with a forming hole 14, one side of the box body 15 is provided with a lifting groove 16, and the support arm 22 is slidably connected in the lifting groove 16.

[0046] The moving mechanism 2 further includes a plurality of side ears 24 arranged in a circumferential array on the cylindrical surface of the pressure plate 23 , and each side ear 24 is sleeved on a corresponding column 31 , and an adjustment rod 26 is fixed to the bottom surface of each side ear 24 , and the adjustment rod 26 passes through the corresponding shell 41 .

[0047] The stabilizing mechanism 3 further includes a first spring 32 mounted on the outside of each column 31 , and the bottom surface of the housing 41 contacts the top of the corresponding first spring 32 . Two side plates 33 are symmetrically fixed on the surface of the column 31 , and each side plate is provided with a wavy guide rail 34 .

[0048] The feeding mechanism 4 also includes a through hole 47 penetrating through one end of the shell 41. The shell 41 is sleeved on the column 31 through the through hole 47, and the shell 41 is slidably connected with the column 31 and the side plate 33 through the through hole 47. A material distribution groove 48 is provided on the top surface of the other end of the shell 41, and the nozzle 46 is located directly above the material distribution groove 48.

[0049] A cloth mechanism 5 is installed on the top surface of the shell 41, and the cloth mechanism 5 includes a plurality of sleeves 52 equidistantly installed on the top surface of the shell 41, and the sleeves 52 are slidably connected to a long rod 53, and a slider 51 is installed at one end of the long rod 53, and the slider 51 is slidably connected to the corresponding guide rail 34, and the other end of the long rod 53 is rotatably connected to a short rod 54, and the end of the short rod 54 is installed on the side of the corresponding rotating block 45.

[0050] The pressure plate 23 drives the mold 25 downward, and after passing the brush head 62, the mold 25 is coated with lubricant, and the pressure plate 23 continues to move downward, and drives the housing 41 to move synchronously, and the through hole 47 on the housing 41 slides relative to the column 31 and the side plate 33, and the housing 41 compresses the first spring 32. At the same time, the pump body 43 is started, and the lubricant in the storage tank 42 is pumped into the rotating block 45 through the pipeline 44, and then sprinkled on the brush head 62 from the nozzle 46, so as to replenish the lubricant for the next coating of the brush head 62. The lubricant used in the process of processing the spline by a press is usually in a paste form, and its paste has strong adhesion but poor fluidity. When sprayed through the nozzle 46, the lubricant is difficult to spread automatically and evenly adhere to the brush head 62, which will cause the brush head 62 to apply the lubricant unevenly, especially for the gaps between the teeth, which are difficult to fully cover with the lubricant. Therefore, the housing 41 is driven to slide downward along the column 31 by the pressure plate 23, and the slider 51 is driven to slide in the guide rail 34 of the side plate 33. Through the restriction of the wavy guide rail 34, the slider 51 drives the long rod 53 slides back and forth horizontally, the long rod 53 drives the short rod 54 to swing, and the short rod 54 drives the rotating block 45 to rotate on the top surface of the shell 41 (the long rod 53 and the short rod 54 are rotatably connected together by a pin shaft, and the pin hole on the long rod 54 and the rotating part of the short rod 54 are clearance-matched to avoid the rotating part getting stuck during the swinging process of the long rod 53 driving the short rod 54), thereby driving the nozzle 46 to swing, which drives the nozzle 46 to swing in a regular fan shape, and can evenly sprinkle the lubricant on the brush head 62, thereby improving the uniformity of the lubricant applied to the brush head 62.

[0051] During the descent of the shell 41, the pump body 43 is turned on for a certain period of time (the nozzle 46 sprays a sufficient amount of lubricant) and is accompanied by the swing of the nozzle 46. During other processes, the pump body 43 is turned off. For example, during the ascending stage of the shell 41, although the material distribution mechanism 5 still drives the nozzle 46 to swing under the action of the guide rail 34, it does not affect the normal operation of other mechanisms.

[0052] Example 3: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 11 The smearing mechanism 6 further includes a toothed belt 63 disposed on the bottom surface of the first slider 61 , and a gear 64 is rotatably connected inside the housing 41 .

[0053] A scraping mechanism 7 is installed inside the other end of the shell 41, and the scraping mechanism 7 includes a second slider 71 slidably connected to the inside of the other end of the shell 41. A scraper 72 and a comb plate 73 are installed at the end of the second slider 71. The comb plate 73 is inserted into the brush head 62. A toothed belt 63 is provided on the top surface of the second slider 71, and the gear 64 is meshed and connected with the toothed belts 63 on the bottom surface of the first slider 61 and the top surface of the second slider 71 at the same time. Side grooves 74 are symmetrically provided on both sides of the second slider 71.

[0054] The housing 41 is provided with a locking mechanism 8, which includes a top rod 81 slidably connected to the housing 41, a second spring 82 being sleeved at the bottom end of the top rod 81, and the top rod 81 being elastically connected to the housing 41 through the second spring 82, a rack 83 being slidably connected to the housing 41, and the rack 83 being meshed with the gear 64, a slot 84 being provided on the side of the bottom end of the rack 83, a fourth spring 88 being installed at the bottom of the rack 83, and the rack 83 being elastically connected to the housing 41 through the fourth spring 88, and a lock head 85 being installed inside the base 12. One end of the lock head 85 is engaged with the card slot 84, and the other end of the lock head 85 is provided with an extrusion hole 86. The bottom end of the top rod 81 is slidably connected to the extrusion hole 86. The lock head 85 is elastically connected to the inside of the shell 41 through the third spring 87. The inside of the shell 41 is also slidably connected with a lock rod 89, and a fifth spring 891 is sleeved on the lock rod 89. The lock rod 89 is elastically connected to the inside of the shell 41 through the fifth spring 891. One end of the lock rod 89 is provided with an extrusion hole 86, and the bottom end of the adjusting rod 26 is slidably connected to the extrusion hole 86 at the end of the lock rod 89.

[0055] In the initial stage, the brush head 62 protrudes from the end of the shell 41 so that the brush head 62 can contact the surface of the mold 25 during the descent of the mold 25. The scraper 72 also protrudes from the end of the shell 41, but the protruding length of the scraper 72 is less than the brush head 62, and the scraper 72 will not contact the mold 25 during the descent of the mold 25; the top surface of the shell 41 is exposed with the push rod 81 and the rack 83, and the top height of the push rod 81 is higher than the top height of the rack 83; inside the shell 41, the bottom end of the adjustment rod 26 is in the extrusion hole at the end of the locking rod 89 The bottom end of the push rod 26 is in contact with the inner wall of the extrusion hole 86, so that the locking rod 89 cannot slide freely, and the fifth spring 891 is in a state of storing force; the bottom end of the push rod 81 is above the extrusion hole 86 at the end of the lock head 85, so that the lock head 85 is inserted into the card slot 84, thereby locking the rack 83, so that the rack 83 cannot slide up and down, thereby controlling the smearing mechanism 6 to prevent the smearing mechanism 6 from shaking.

[0056] The pressure plate 23 drives the side ear 24 and the mold 25 to descend, and the brush head 62 applies lubricant. At the same time, the adjustment rod 26 at the bottom of the side ear 24 descends and passes through the corresponding extrusion hole 86, thereby releasing the lock rod 89, and the fifth spring 891 drives the lock rod 89 to move a certain distance to the left (as shown in the attached figure). Fig. 9The pressure plate 23 first contacts and presses down the ejector pin 81, causing the ejector pin 81 to slide a certain distance into the shell 41, and the ejector pin 81 compresses the second spring 82, and the bottom of the ejector pin 81 squeezes the eight pairs of squeezing holes 86, causing the lock head 85 to slide out of the card slot 84, thereby releasing the lock on the rack 83. The third spring 87 is compressed during the sliding process of the lock head 85. When the ejector pin 81 is lowered to the same height as the rack 83, the pressure plate 23 drives the ejector pin 81 and the rack 83 to slide into the shell 41 together. The rack 83 compresses the fourth spring 88 and drives the gear 64 to rotate, and the gear 64 passes through the compression of the fourth spring 88. The toothed belt 63 drives the first slider 61 to slide toward the inside of the shell 41, and the first slider 61 drives the brush head 62 to slide, and the brush head 62 enters the material feeding groove 48; the second slider 71 slides outward, driving the scraper 72 to move away from the shell 41, and at the same time drives the comb plate 73 to move. The movement directions of the brush head 62 and the comb plate 73 are opposite. In the process of applying lubricant, the brush head 62 will inevitably carry some impurities such as metal chips adhered to the mold 25, which will contaminate the brush head 62 and the newly supplied lubricant. Therefore, the comb plate 73 is inserted into the brush head 62, and the two move in opposite directions, so as to scrape the brush head 62 and scrape off the lubricant with impurities.

[0057] When the rack 83 moves to the lowest point, the scraping mechanism 7 is in place, and the locking rod 89 is inserted into the slot 84, locking the rack 83 again to prevent the scraping mechanism 7 from shaking. The mold 25 enters the forming hole 14 and the spline sleeve is processed. After completion, the hydraulic push rod 21 drives the pressure plate 23 to rise through the support arm 22. Under the elastic force of the first spring 32, the feeding mechanism 4 moves synchronously with the pressure plate 23 until the first spring 32 returns to its initial state. The housing 41 then stops, and the pressure plate 23 continues to drive the mold 25 to rise. Then, when the mold 25 passes, the scraper 72 scrapes the lubricant on the surface of the mold 25 from top to bottom. The scraper 72 is designed to have the same tooth shape as the mold 25, which can better fit the surface of the mold 25 and has a better effect in scraping the lubricant.

[0058] Finally, the pressure plate 23 drives the mold 25 to reset, the adjusting rod 26 returns to the initial state, and pushes the locking rod 89, so that the other end of the locking rod 89 slides out of the slot 84. Then, the fourth spring 88 pushes the rack 83 to rise and return to the initial position, and the lock head 85 is inserted into the slot 84 again to lock the rack 83 (the push rod 81 stops rising when the shell 41 stops, and the pressure plate 23 moves away from the shell 41. The lock head 85 is now acted upon by the elastic force of the third spring 87 and contacts the side of the rack 83). During the rising process of the rack 83, the smearing mechanism 6 is pushed out again, and the scraping mechanism 7 is retracted.

[0059] Example 4: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 11A recovery mechanism 9 is installed inside the second slider 71, and the recovery mechanism 9 includes a material receiving box 91 rotatably connected to the bottom of the second slider 71. Both sides of the material receiving box 91 are elastically connected to the second slider 71 through torsion springs 92. Adjustment grooves 93 are symmetrically provided at the two end portions of the material receiving box 91, and the adjustment grooves 93 are aligned with the corresponding side grooves 74. A lower pressing plate 94 is installed inside the shell 41, and the top side portion of the lower pressing plate 94 is slidably connected to the side groove 74. An oblique groove 95 is provided on the lower pressing plate 94. A fork rod 96 is slidably connected to the inside of the shell 41. One end of the fork rod 96 is slidably connected to the corresponding oblique groove 95. The fork rod 96 is elastically connected to the inside of the shell 41 through a sixth spring 97. An extrusion block 98 is fixed to the other end of the fork rod 96, and the extrusion block 98 is located below the extrusion hole 86 at the end of the locking rod 89. A recovery box 99 is embedded in the bottom of the shell 41.

[0060] When the second slider 71 drives the scraper 72 to slide out of the shell 41, the second slider 71 will drive the receiving box 91 to slide synchronously. The receiving box 91 is located below the scraper 72 and can receive the lubricant impurities scraped off by the scraper 72 and collect the impurities to avoid polluting the working environment. In addition, when the second slider 71 slides, the top end of the lower pressure plate 94 slides in the side groove 74.

[0061] When the pressure plate 23 begins to descend, the side ear 24 drives the adjustment rod 26 to slide downward, and the bottom end of the adjustment rod 26 contacts and pushes the extrusion block 98 to move horizontally. The extrusion block 98 drives the fork rod 96 to slide in the housing 41, and the other end of the fork rod 96 slides to the left in the inclined groove 95 (as shown in the attached figure). Fig.10 The lower pressing plate 94 is lowered, and the top end of the lower pressing plate 94 is in the side groove 74 and the adjustment groove 93 (as shown in the attached Figure 8 As shown, the lower part of the left end of the side groove 74 is an open structure, which is convenient for the lower pressure plate 94 to detach from the side groove 74), and the lower pressure plate 94 descends, and drives the receiving box 91 to rotate in the second slider 71 through the adjustment groove 93. During the rotation of the receiving box 91, the torsion spring 92 accumulates force, and the receiving box 91 is tilted, so that the impurities received by the receiving box 91 can be dumped into the recovery box 99. The recovery box 99 is embedded in the bottom surface of the shell 41 and can be easily taken out to dump the lubricant impurities collected inside.
