AI Technical Summary
Existing titanium alloy plate grinding equipment has problems such as difficulty in grinding both sides simultaneously and the grinding rollers rotating in the same direction, resulting in burr residue in the direction of rotation. This is especially problematic for large or heavy plates, where the flipping process is cumbersome and the burr shearing force is insufficient.
The four-roll synchronous grinding equipment, including the design of the top and bottom grinding rollers rotating in opposite directions, combined with the stepping conveyor mechanism, realizes the synchronous grinding of the upper and lower surfaces of the titanium alloy sheet, and removes burrs by reverse shearing force.
This has resulted in a 40%-60% reduction in grinding time for titanium alloy sheets, a 3-fold increase in burr shearing force, and improved finished product quality and grinding efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of titanium alloy product manufacturing technology, and in particular to a grinding device for titanium alloy product manufacturing. Background Technology
[0002] The grinding process in the production of titanium alloy products is a core step in improving their surface performance and quality. It plays a particularly crucial role in the processing of titanium alloy sheets. It can remove surface defects by mechanically rubbing away oxide scale, burrs, microcracks, and work-hardened layers generated on the surface of the sheet due to rolling or cutting, thus preventing such defects from affecting the adhesion of subsequent coatings or causing stress concentration.
[0003] In the actual grinding production of titanium alloy sheets, after grinding one side, the sheet needs to be flipped for grinding the other side, which requires additional time and manpower. This flipping process can be particularly cumbersome for large or heavy titanium alloy sheets. Furthermore, when the grinding roller rotates clockwise, the normal component (Fn) and tangential component (Ft) of the cutting edge on the sheet form a specific angle. When the angle between the burr direction and Ft is less than 45°, the shear force on the burr decreases by 60%, leading to a 3-fold increase in the probability of burr residue. Therefore, to solve these problems, a grinding device for titanium alloy product manufacturing is proposed. Utility Model Content
[0004] The purpose of this invention is to solve the shortcomings of existing technologies, such as the difficulty in synchronous grinding of both sides and the residual burrs caused by the unidirectional rotation of the grinding rollers, and to propose a grinding equipment for the production of titanium alloy products.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A grinding device for producing titanium alloy products includes a conveying mechanism and a titanium alloy plate. The conveying mechanism includes a guide rail, on which conveying chains are symmetrically arranged. The titanium alloy plate is mounted on the conveying chains, which are capable of step-by-step movement and are used to transport the titanium alloy plate.
[0007] A grinding assembly is provided on the guide rail. The grinding assembly includes a dustproof plate. A top first grinding roller and a top second grinding roller are rotatably arranged inside the dustproof plate. The top first grinding roller and the top second grinding roller rotate in opposite directions. A bottom first grinding roller and a bottom second grinding roller are rotatably arranged inside the guide rail. The bottom first grinding roller and the bottom second grinding roller rotate in opposite directions. The top first grinding roller, the top second grinding roller, the bottom first grinding roller, and the bottom second grinding roller are used together to simultaneously grind the upper and lower surfaces of the titanium alloy plate.
[0008] The above technical solution further includes:
[0009] The conveying mechanism also includes a control motor, which is mounted on the outside of the guide rail. A main gear shaft and a driven gear shaft are rotatably connected inside the guide rail, and the main gear shaft and the driven gear shaft are sleeved and connected to the conveying chain.
[0010] The main gear shaft extends to the outside of the guide rail and is equipped with a grooved wheel at one end near the control motor. A rotating shaft is installed at the output end of the control motor. A dial wheel is fixedly connected to the outside of the rotating shaft. The grooved wheel and the dial wheel mesh with each other.
[0011] The rotating shaft is rotatably mounted inside the guide rail, and a drive gear is fixedly connected to the end of the rotating shaft away from the control motor. The drive gear is sleeved and connected to the main chain.
[0012] The grinding assembly also includes a driven gear, which is installed at one end of the top first grinding roller extending to the outside of the dustproof plate, and is sleeved and connected to the main chain.
[0013] The top first grinding roller and the top second grinding roller are both fixedly connected to the top drive flywheel at the end near the control motor, and a top reverse belt is sleeved between the two top drive flywheels.
[0014] The bottom first grinding roller and the bottom second grinding roller are both fixedly connected to the bottom drive flywheel at the end near the drive gear. A bottom reverse belt is sleeved between the two bottom drive flywheels. The top second grinding roller and the bottom second grinding roller are also fixedly connected to the drive gear at the end near the drive gear. A drive chain is sleeved between the two drive gears.
[0015] The conveyor chain is equipped with multiple clamps, and the clamps are threaded with fixing bolts. The titanium alloy plate is disposed inside the multiple clamps.
[0016] This utility model has the following beneficial effects:
[0017] 1. In this utility model, the traditional process requires two clamping, positioning and inspection. This equipment uses four rollers to grind synchronously, which reduces the processing time of a single piece by 40%-60% (taking 0.5mm thick TC4 plate as an example, the traditional process requires 12 minutes / piece, while this equipment only requires 5 minutes / piece). In addition, the conveyor chain stepping drive realizes the dynamic matching between the grinding components and the plate, which improves the quality of the finished product.
[0018] 2. In this utility model, the top first and second grinding rollers and the bottom first and second grinding rollers are combined clockwise and counterclockwise to form a dual "shearing-peeling" force, which increases the shearing force on the burrs by 3 times. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example
[0026] like Figures 1-4 As shown, the present invention proposes a grinding equipment for the production of titanium alloy products. The conveying mechanism includes a guide rail 2, on which conveying chains 23 are symmetrically arranged. The titanium alloy plate 4 is installed on the conveying chain 23. The conveying chain 23 can move in a stepping motion and is used to transport the titanium alloy plate 4.
[0027] A grinding assembly is provided on the guide rail 2. The grinding assembly includes a dustproof plate 1. A top first grinding roller 10 and a top second grinding roller 11 are rotatably arranged inside the dustproof plate 1. The top first grinding roller 10 and the top second grinding roller 11 rotate in opposite directions. A bottom first grinding roller 12 and a bottom second grinding roller 13 are rotatably arranged inside the guide rail 2. The bottom first grinding roller 12 and the bottom second grinding roller 13 rotate in opposite directions. The top first grinding roller 10, the top second grinding roller 11, the bottom first grinding roller 12, and the bottom second grinding roller 13 are used together to simultaneously grind the upper and lower surfaces of the titanium alloy plate 4.
[0028] Furthermore, the conveyor chain 23 in the conveying mechanism drives the titanium alloy plate 4 to move in a stepping motion. At the same time, the top first grinding roller 10 and the top second grinding roller 11 grind the top of the titanium alloy plate 4, while the bottom first grinding roller 12 and the bottom second grinding roller 13 grind the bottom of the titanium alloy plate 4. The two grinding rollers on the same side rotate in opposite directions, forming a counter-shear flow field, which eliminates the "directional strengthening" effect of burrs in traditional co-directional grinding. The bottom grinding rollers are supported by bearing seats in the guide rail 2 and form a spatially opposite staggered layout with the top roller group to ensure that the grinding force vectors of the upper and lower surfaces are opposite, thus balancing the force on the plate.
[0029] The conveying mechanism also includes a control motor 20, which is installed on the outside of the guide rail 2. A main gear shaft 21 and a driven gear shaft 22 are rotatably connected inside the guide rail 2. The main gear shaft 21 and the driven gear shaft 22 are sleeved and connected to the conveying chain 23.
[0030] A grooved wheel 26 is installed at the end of the main gear shaft 21 that extends to the outside of the guide rail 2 and is close to the control motor 20. A rotating shaft 3 is installed at the output end of the control motor 20. A push wheel 27 is fixedly connected to the outside of the rotating shaft 3. The grooved wheel 26 and the push wheel 27 mesh with each other.
[0031] Furthermore, the control motor 20 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the actuating wheel 27 to rotate, causing the pin on it to move in a circular motion. The pin engages with the through groove of the grooved wheel 26. The through groove is distributed in a circular array. Therefore, when the pin moves in a circular motion, it drives the grooved wheel 26 to rotate in a step-by-step manner, thereby driving the conveyor chain 23 to move the titanium alloy plate 4 in a step-by-step manner. This design is intended to ensure that the titanium alloy plate 4 has sufficient contact time with the grinding roller, thereby improving the grinding quality.
[0032] The rotating shaft 3 is rotatably mounted inside the guide rail 2. The end of the rotating shaft 3 away from the control motor 20 is fixedly connected to the drive gear 30, and the drive gear 30 is sleeved and connected to the main chain 31.
[0033] Furthermore, the rotating shaft 3 drives the main chain 31 to rotate in a circular motion, and the main chain 31 drives the grinding assembly to perform grinding.
[0034] The grinding assembly also includes a driven gear 32, which is mounted on one end of the top first grinding roller 10 extending to the outside of the dustproof plate 1, and is sleeved and connected to the main chain 31.
[0035] The top first grinding roller 10 and the top second grinding roller 11 are both fixedly connected to the top transmission flywheel 14 at the end near the control motor 20, and a top reverse belt 15 is sleeved between the two top transmission flywheels 14.
[0036] Bottom first grinding roller 12 and bottom second grinding roller 13 are both fixedly connected to bottom drive flywheel 16 at the end near the drive gear 30. Bottom reverse belt 19 is sleeved between the two bottom drive flywheels 16. Top second grinding roller 11 and bottom second grinding roller 13 are also fixedly connected to drive gear 17 at the end near the drive gear 30. Drive chain 18 is sleeved between the two drive gears 17.
[0037] Furthermore, the control motor 20 starts and drives the drive gear 30 to rotate. The drive gear 30 is sleeved and connected to the main chain 31. Through the power transmission of the main chain 31, the top first grinding roller 10 rotates. At the same time, the top first grinding roller 10 and the top second grinding roller 11 are both fixedly connected to the top transmission flywheel 14 at the end near the control motor 20. The top reverse belt 15 is sleeved and connected between the two top transmission flywheels 14. With the help of the top reverse belt 15, the top second grinding roller 11 and the top first grinding roller 10 rotate synchronously in opposite directions.
[0038] Furthermore, a transmission gear 17 is fixedly connected to one end of the top second grinding roller 11 and the bottom second grinding roller 13 near the drive gear 30, and a transmission chain 18 is sleeved between the two transmission gears 17, so that the top second grinding roller 11 and the bottom second grinding roller 13 can rotate synchronously.
[0039] Furthermore, bottom first grinding roller 12 and bottom second grinding roller 13 are both fixedly connected to bottom drive flywheel 16 at the end near the drive gear 30. Bottom reverse belt 19 is sleeved between the two bottom drive flywheels 16, and bottom first grinding roller 12 and bottom second grinding roller 13 are made to rotate synchronously in opposite directions through bottom reverse belt 19.
[0040] Furthermore, the top first grinding roller 10, the top second grinding roller 11, the bottom first grinding roller 12, and the bottom second grinding roller 13 work together to complete the grinding action;
[0041] Multiple clamps 24 are installed on the conveyor chain 23, and fixing bolts 25 are threadedly connected to the clamps 24. Titanium alloy plates 4 are set inside the multiple clamps 24.
[0042] Furthermore, multiple clamping platforms 24 are installed on the conveyor chain 23, and fixing bolts 25 are threaded onto the clamping platforms 24. By turning the fixing bolts 25, the titanium alloy plate 4 is clamped. The operation of the conveyor chain 23 drives the clamping platforms 24 and the titanium alloy plate 4 to move, so that the titanium alloy plate 4 passes through each grinding roller in sequence for grinding.
[0043] In this embodiment, before grinding the titanium alloy plate 4, the operator first installs the titanium alloy plate 4 on the conveyor chain 23 using the clamping platform 24 and fixing bolt 25. Then, the control motor 20 is started. The control motor 20 realizes the step-by-step movement of the titanium alloy plate 4 through the grooved wheel 26 and the actuating wheel 27. At the same time, the control motor 20 drives the grinding roller to grind the upper and lower surfaces of the titanium alloy plate 4 synchronously. The grinding rollers on the same side are set to rotate in opposite directions, which is beneficial for removing burrs.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
