Description

Technical Field

[0001] The utility model relates to the technical field of band saw blade welding tooth machines, in particular to an alloy band saw blade welding tooth machine. Background Art

[0002] At present, when processing band saw blades, in order to improve the strength, wear resistance and service life of steel saw blades, the method of first processing the saw blade tooth roots and welding alloy tool heads on the tooth roots is usually adopted for processing band saw blades.

[0003] In the prior art, a Chinese patent document with the authorization announcement number CN209288555U discloses a band saw blade welding tooth machine, which includes a band saw blade guide groove that is arranged on a pedestal along the transverse direction of the pedestal, is used for movably arranging a base band, and has an opening vertically upward, a push belt mechanism that is arranged on the pedestal and is used for pushing the base band to intermittently move in the band saw blade guide groove, and a clamping belt mechanism that is arranged above the band saw blade guide groove and is used for intermittently clamping the band saw blade.

[0004] However, the above solution still has the following deficiencies in use:

[0005] 1. The inner size of the guide groove is matched with the thickness of the band saw blade. When the band saw blade moves along the path in the guide groove, the surface of the band saw blade will rub against the inner wall of the guide groove.

[0006] 2. When the inner size of the guide groove is larger than the thickness of the band saw blade, the band saw blade will tilt inside the guide groove, resulting in that the push belt mechanism cannot be smoothly connected with the tooth grooves of the band saw blade. At the same time, when the clamping belt mechanism intermittently clamps the band saw blade, the tooth roots of the band saw blade will be translated relative to the positions of the alloy tool heads.

There are two roller sets b4 provided at the top of the roller set a2, and the two roller sets b4 are arranged oppositely. Among them, guide plates 7 are provided at one end of each of the two roller sets b4 to guide the end of the band saw blade during use so that it moves between the two roller sets b4. The height of the roller set b4 is less than the width of the band saw blade to avoid the situation where the roller set b4 obstructs the welding point during the welding state. The length of the roller set b4 is less than the length of the roller set a2, and the roller set b4 and the roller set a2 are coaxially placed at the central position to support the ends of the band saw blade that have been welded and are to be welded during use, avoiding the end of the band saw blade applying tensile force to the middle part due to its own gravity.

[0042] The adjusting assembly 3 is installed at the top of one side of the roller set a2, and its side is connected to the roller set b4 and extends to the other side of the roller set a2 to move one roller set b4 towards the other roller set b4 and clamp the band saw blade during use.

[0045] In this embodiment, the adjusting assembly 3 drives one roller set b4 to move towards the other roller set b4, elastically adjusting the roller spacing between the two roller sets b4 to clamp and place band saw blades of different thicknesses between the two roller sets b4. At the same time, the driving assembly 6 drives the connecting frame 5 to move upward, making the distance between the connecting frame 5 and the roller set a2 greater than the width of the band saw blade, and placing the band saw blade on the roller set a2. One end of the band saw blade moves between the two roller sets b4 through the guide plate 7, and the position of the roller set b4 is adjusted according to the thickness of the band saw blade. The roller set a2 supports the whole band saw blade, and the driving assembly 6 drives the connecting frame 5 to descend, making the connecting frame 5 connect with the tooth root of the band saw blade. Then, the driving assembly 6 drives the connecting frame 5 to translate, making the tooth root of the connecting frame 5 move towards the alloy head welding point. When the tooth root moves to the welding position, the driving assembly 6 drives the connecting frame 5 to move upward, separating the connecting frame 5 from the tooth root, and making a circular movement path for resetting, so that the driving assembly 6 drives the connecting frame 5 to move the tooth root of the band saw blade to the welding position once.

[0054] The frame body 51 is mounted on the upper end surface of the push plate 52 and is connected to the upper end surface of the tooth root of the band saw blade, and the middle part extends downward to the side of the connecting frame 5 for being connected to the upper end surfaces of multiple tooth roots of the band saw blade and translating synchronously with the band saw blade through the push plate 52 in the use state, so as to horizontally translate the band saw blade and prevent the band saw blade from lifting;

[0055] The number of the vertical plates 53 is two. The two vertical plates 53 are arranged side by side and mounted on the lower end surface of the frame body 51 and are slidably connected to the driving component 6. A card slot for the driving component 6 is left between the two vertical plates 53; multiple groups of the above card slots are provided; for wrapping the driving component 6 by the card slots by the frame body 51 in the use state, so that the connecting frame 5 has a support point on the driving component 6.

[0056] In an optional embodiment, the driving component 6 includes a fixing plate 61, a motor 62 and a connecting block 63;

[0057] The fixing plate 61 is mounted on the upper end surface of the workbench 1, and a groove for accommodating the connecting rod 54 is provided on the side; wherein, the groove is annular, and the projection of the edge of the groove is square, and the corners of the groove are arc-shaped for enabling the connecting rod 54 to move smoothly in the arc, for making the connecting rod 54 perform actions of descending (ascending), translating, ascending (descending), and translating and resetting in the use state;

[0058] The motor 62 is installed on the side of the fixed plate 61, and the output shaft is located in the middle of the groove of the fixed plate 61, passing through the fixed plate 61 and extending to the other side of the fixed plate 61 to drive the connecting block 63 to rotate in the use state;

The saw blade is placed on the roller group a2, and one end of the saw blade moves towards the space between the two roller groups b4 through the guide plate 7. The saw blade is placed between the two roller groups b4, and the roller group a2 supports the whole saw blade. The motor 62 operates to drive the connecting block 63 to rotate. The connecting block 63 drives the connecting rod 54 to move inside the groove of the fixed plate 61 through the waist-shaped hole, so that the connecting rod 54 drives the frame body 51 to move up and down according to the shape of the groove of the fixed plate 61, so that the frame body 51 drives the push plate 52 to be inserted into the tooth grooves of the saw blade and connected to the tooth roots. The frame body 51 contacts the upper end surfaces of the multiple tooth roots of the saw blade to limit the movement of the saw blade. By continuously rotating the motor 62, the frame body 51 drives the push plate 52 to move horizontally according to the shape of the groove of the fixed plate 61, so that the push plate 52 pushes the tooth roots to move, so that the saw blade moves the tooth roots towards the welding point on the roller group a2. At the same time, through the shape of the groove of the fixed plate 61, the connecting frame 5 is reset, and the rotation of the motor 62 moves the connecting rod 54 in a circular motion through the groove of the fixed plate 61 and the through hole of the vertical plate 53, so that the frame body 51 performs a circular working path of descending, translational pushing, ascending, and translational resetting for secondary pushing, so that the frame body 51 drives the push plate 52 to push the multiple tooth roots of the saw blade to move to the welding position in sequence.
