[0016] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0017] like Figure 1-2As shown, a saw blade substrate heat treatment equipment includes a furnace body 1, a furnace cavity 11 is provided inside the furnace body 1, a movable door 12 is provided on the side wall of the furnace body 1, and a plurality of electric radiation tubes 13 are symmetrically provided on the inner wall of the furnace cavity 11 corresponding to the two sides of the movable door 12, including a base 2 arranged at the bottom of the furnace body 1 and slidingly matched with the bottom of the furnace body 1, a support seat 14 for placing batches of circular saw blades is provided at the bottom of the furnace body 1, a first annular gear group 15 is provided on the outer wall of the furnace body 1, a driving motor 21 connected to the base 2 is provided on the adjacent side of the furnace body 1, and a first transmission gear 211 engaged with the first annular gear group 15 is provided on the output shaft of the driving motor 21, the support seat 12 is rotatably connected to the base 2, and the support seat 12 can rotate in different directions relative to the furnace body 1; a fixed cavity 18 for accommodating the movable door 12 is provided on the side wall of the furnace body 1, and the movable door 12 can move circumferentially in the fixed cavity 18, and the first annular gear group 15 is located below the movable door 12.

[0018] The above-mentioned electric radiation tube is a product currently available on the market and is prior art, and will not be described in detail here. When the above-mentioned saw blades are subjected to tempering heat treatment, batches of saw blades are fixed by external clamps and placed on the top surface of the support seat, the movable door moves in the fixed cavity to form a closure for the furnace cavity, the electric radiation tube is started to heat the electric radiation tube in the furnace cavity, the drive motor drives the first transmission gear to rotate, and drives the furnace body to rotate on the base through engagement with the first annular gear group, the furnace body drives the electric radiation tube to rotate around the saw blade, uniformly heating the batch of saw blades, making the saw blades heated more evenly and stably, and the support seat is rotatably connected to the base, so that when the furnace body rotates relative to the base, it can avoid the support seat rotating synchronously with the base and failing to achieve uniform heat treatment of the saw blade.

[0019] like Figure 2 As shown, an annular groove 22 is provided at the edge of the top surface of the base 2, and an annular slider 16 is provided on the bottom surface of the furnace body 1 to cooperate with the annular groove 22. A number of balls 221 are laid on the bottom of the annular groove 22. When the annular slider 16 is located in the annular groove 22, the upper top surface of the ball 221 abuts against the bottom surface of the annular slider 16; the above-mentioned several balls are laid in the annular groove, and the annular slider is always located in the annular groove and abuts against the balls. When the furnace body rotates, the annular groove is used to limit the rotation of the furnace body to avoid the furnace body from deviating and affecting the rotation stability. The setting of the annular slider and the balls maintains the smooth rotation of the furnace body and ensures that the furnace body rotates stably on the base.

[0020] like Figure 2-3As shown, the bottom of the support seat 12 is provided with a rotating shaft 121 rotatably connected to the base 2, and the rotating shaft 121 and the support seat 12 are coaxially arranged with the annular slider 16 and the annular slide groove. A through hole 111 is provided on the circumferential side of the rotating shaft 121 at the bottom of the furnace chamber 11, and a second annular gear set 112 is provided on the inner wall of the through hole 111. A third annular gear set 122 corresponding to the second annular gear set 112 is provided on the side wall of the rotating shaft 121. A second transmission gear 17 is provided between the rotating shaft 121 and the through hole 111, which is respectively meshed with the second annular gear set 112 and the third annular gear set 122. An annular sealing block 141 connected to the bottom of the furnace chamber 11 is provided at the bottom of the support seat 14, and the top surface of the annular sealing block 141 is slidably matched with the bottom surface of the support seat 14; the support seat is supported by the rotating shaft. The support rotates on the base. When the furnace body is driven to rotate, the second annular gear set in the through hole drives the second transmission gear to rotate in the same direction by meshing with the second transmission gear. The second transmission gear drives the rotating shaft to rotate in the opposite direction relative to the second annular gear set by meshing with the third annular gear set, thereby driving the support seat and the saw blade on the support seat to rotate in the opposite direction relative to the furnace body and the electric radiation tube. While the furnace body and the electric radiation tube rotate around the saw blade, the saw blade rotates on itself, thereby effectively enhancing the sufficient heat treatment of the saw blade and further enhancing the uniformity of heating of the saw blade. The setting of the above-mentioned annular sealing block can seal the structure at the through hole, reduce the influence of high temperature on structural components, and at the same time support the rotation of the support seat to ensure the stability of the support seat when driving the saw blade.

[0021] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
