Description

Technical Field

[0001] The present application relates to the technical field of titanium forging processing, and in particular to a sawing auxiliary device for improving the sawing of titanium forging forming bodies. Background Art

[0002] Titanium forgings refer to titanium alloy products made by forging. They have many characteristics, including high strength, high hardness, excellent high and low temperature performance, strong corrosion resistance, etc. Compared with other metals, they also have better biocompatibility and are widely used in the field of medical technology. Titanium forgings can be divided into different types, such as plates, bars, pipes, rings, flanges, targets, gears, etc. according to their shapes and sizes.

[0003] There are many forging processes for titanium forgings, including free forging, open die forging, closed die forging, extrusion die forging, multi-directional die forging, partial die forging and isothermal die forging. The main process includes melting titanium sponge or titanium waste at high temperature to form an ingot structure, and then forging it through a forging press in a heated state to form titanium forgings. According to the finished product structure and the forging method of the forging press, conventional titanium forgings include square and long strip structures, or post-plate structures. Since forging is to apply a forging force on the surface of the ingot to deform it, the surface flatness of the formed titanium forging is poor. As an intermediate billet, it still needs further machining in the future.

[0004] Before machining, the surface of the titanium forging needs to be trimmed first. The specific method is as follows: Since titanium forgings are usually long strips with a length greater than the width, it is not convenient to clamp them vertically for milling. Therefore, the treatment of their end faces is usually as shown in the attached manual. Figure 3-4 As shown, the titanium forging is clamped on a sawing machine and then sawed. After sawing, the flat end face is clamped on a milling machine to perform large-area milling on the surface and side of the titanium forging.

[0005] like Figure 5 As shown in the figure, since the surface flatness of the titanium forging is poor in the later stage of forming, more pits are formed during the forging process. Therefore, after being clamped by the clamping plate of the sawing machine, the clamping plate cannot be completely flat against the side wall of the titanium forging (such as Figure 5 As shown in a in the figure). Then as Figure 6 As shown in the figure, during the later sawing process, the unidirectional sawing force will cause the titanium forging to deflect ( Figure 6 The saw blade is driven to rotate ( Figure 7 As shown in the figure, due to the small thickness of the saw blade, the saw blade will break under the torsion ( Figure 8 shown).

[0006] When the saw blade can resist the torsion of the titanium forging, the torsion of the titanium forging will cause the end face sawing to deflect, and then when the surface and side milling are performed in the later clamping, the milling amount will increase ( Fig. 9 The dotted line in the middle is the milling surface), which reduces the size of the titanium forging and increases the waste of material and energy consumption in the processing process. Summary of the invention

[0007] In view of the above-mentioned problems, the present application aims to provide a sawing auxiliary device for improving the titanium forging formed body. By setting a fitting and clamping component, it can be attached to the titanium forging with different side wall structures on the basis of the clamping plate, thereby solving the problem of unstable clamping of the titanium forging by the clamping plate, and thus overcoming the deflection of the titanium forging during the sawing process, ensuring that the rear end face of the sawing is perpendicular to the titanium forging as a whole, reducing the milling amount during the later milling process, and increasing the size of the formed body.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a sawing auxiliary device for improving the sawing of titanium forging formed bodies, including a sawing machine, which has a sawing platform composed of a plurality of rollers arranged at intervals, and clamping plates are symmetrically arranged on both sides of the front end of the sawing platform, characterized in that: a fitting and clamping member that fits the surface shape of the titanium forging is arranged on each of the clamping plates, and a mechanism for driving the titanium forging to turn is also arranged on the sawing platform.

[0009] Preferably, the fitting and clamping member is a clamping screw which is arranged on each of the clamping plates at intervals and can be pressed against different positions of the titanium forging.

[0010] Preferably, the end of each pressing screw in contact with the titanium forging is configured as a spherical structure.

[0011] Preferably, the turning mechanism is a support plate arranged between adjacent rollers in the middle of the sawing platform, a vertical adjustment rod is rotatably arranged at the bottom of the support plate, and the support plate is adjusted up and down to drive the titanium forging to contact or disengage from the rollers.

[0012] The beneficial effect of the present application is that the sawing auxiliary device can be attached to titanium forgings with different side wall structures on the basis of the clamping plate through the provided fitting and clamping component, thereby solving the problem of unstable clamping of the titanium forgings by the current clamping plate, and thus overcoming the deflection of the titanium forgings during the sawing process, ensuring that the rear end face of the sawing is perpendicular to the titanium forging as a whole, reducing the milling amount during the later milling process, and increasing the size of the formed body.

[0013] By setting up a turning mechanism, the titanium forging can be driven to turn on the sawing platform after the titanium forging is separated from the clamping plate, thereby solving the problems of long turning cycle and poor safety of the sling, and effectively improving the processing efficiency of continuous sawing.

[0031] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0032] See attached Figures 1 to 14 The sawing auxiliary device for improving the titanium forging forming body shown in the figure comprises a sawing machine 1, which has a sawing platform composed of a plurality of rollers 2 arranged at intervals, and clamping plates 3 are symmetrically arranged on both sides of the front end of the sawing platform. When sawing the end of the titanium forging, the titanium forging is clamped between the symmetrical clamping plates 3 of the sawing machine, and the length of the sawing end is adjusted (by driving the titanium forging to move on the roller 2), and then the sawing machine drives the saw blade to move downward to realize the sawing operation of the end of the titanium forging.

[0033] In order to solve the problem that the poor surface flatness of the titanium forging causes deflection during the sawing process, which in turn leads to excessive subsequent milling and affects the size of the titanium forging formed body, the present application provides a fitting clamping component that fits the surface shape of the titanium forging on each of the clamping plates 3. On the basis of the clamping plate 3, it can be attached to titanium forgings with different side wall structures, thereby solving the current problem of unstable clamping of the titanium forging by the clamping plate 3, thereby overcoming the deflection of the titanium forging during the sawing process, ensuring that the rear end face of the sawing is perpendicular to the titanium forging as a whole, reducing the milling amount during the subsequent milling process, and increasing the size of the formed body.

[0034] like Fig.11 As shown, after the sawing of one end of the titanium forging is completed, the titanium forging needs to be moved and separated from the clamping plate 3, and then the titanium forging is lifted and rotated with a sling to saw the other end. The volume of the titanium forging is usually large, and a single lifting rope can easily cause the titanium forging to deflect and fall off, which poses certain safety hazards. At the same time, a crane is required for the lifting and rotation, which makes the lifting and rotation cycle long, and the processing efficiency cannot be effectively improved during continuous sawing. Therefore, in order to solve this problem, the present application also provides a turning mechanism for driving the titanium forging at the sawing platform, which can drive the titanium forging to turn at the sawing platform after the titanium forging is separated from the clamping plate, thereby solving the problem of long turning cycle and poor safety of the sling, and effectively improving the processing efficiency of continuous sawing.

[0035] Specifically, Fig.10 As shown, the fitting and clamping member is a clamping screw 4 which is arranged at intervals on each of the clamping plates 3 and can be pressed against different positions of the titanium forging. After adjusting the sawing length of the end of the titanium forging, the clamping plate 3 is first abutted against the side wall of the titanium forging, and then the clamping screw 4 is rotated to make its end abut against different positions of the side wall of the titanium forging, thereby achieving a stable clamping effect on titanium forgings with different structural surfaces, effectively overcoming the problem of titanium forging deflection caused by the sawing force of the saw blade in subsequent sawing, and thereby ensuring the forming amount of subsequent milling processing.

[0036] Since the surface of the titanium forging is an irregular structure, in order to make each pressing screw 4 stably abut against the side wall of the titanium forging, preferably, the end of each pressing screw 4 that contacts the titanium forging is set to a spherical structure. The spherical structure can stably abut against the pit on the side wall of the titanium forging, thereby improving the stability of the titanium forging clamping.

[0037] In order to facilitate the rapid rotation of titanium forgings, Figure 12-14 As shown, the turning mechanism is a support plate 5 disposed between the adjacent rollers 2 at the middle position of the sawing platform, and a vertical adjustment rod 6 is rotatably disposed at the bottom of the support plate 5. The support plate 5 is adjusted up and down to drive the titanium forging to contact or separate from the roller 2. After the sawing of one end of the titanium forging is completed and the clamping plate 3 is removed, the vertical adjustment rod 6 is rotated to make the support plate 5 rise and lift the titanium forging, and the titanium forging is separated from the contact with the roller 2. Then the titanium forging is rotated (the support plate 5 is preferably rotatably connected to the vertical adjustment rod 6), so that the titanium forging can be quickly turned around, as shown in FIG. Fig.13 As shown, the vertical adjustment rod 6 is then rotated in the opposite direction to descend, so that the titanium forging contacts the roller 2 again, and then the titanium forging is driven to move so that its end enters the lowered saw blade and is clamped again, so that the sawing operation of the other end can be realized.

[0038] The principle of the present application is: when sawing the end of a titanium forging, it is hoisted and placed on the roller 2 of the sawing machine, and its end is driven to enter under the saw blade, and then it is first abutted against the side wall of the titanium forging through the clamping plate 3, and then the clamping screw 4 is rotated to make its end abut against different positions of the side wall of the titanium forging, and then the sawing machine drives the saw blade downward to complete the sawing of the end.

[0039] After sawing one end of the titanium forging is completed and the clamping plate 3 is removed, the vertical adjusting rod 6 is rotated to make the support plate 5 rise and lift the titanium forging, and the titanium forging is separated from the contact with the roller 2. Then the titanium forging is rotated (the support plate 5 is preferably rotatably connected to the vertical adjusting rod 6) to achieve a rapid turn of the titanium forging, and then the vertical adjusting rod 6 is rotated in the opposite direction to descend, so that the titanium forging contacts the roller 2 again, and then the titanium forging is driven to move so that its end enters the lowering of the saw blade and is clamped again to achieve the sawing operation of the other end.

[0040] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
