[0025] like Figure 4-5 As shown, this example can achieve the effect of heating the metal part.

[0026] Since the heat treatment device includes a heating tube 101, a heating wire 103 is arranged on the inner wall of the heating tube 101, and the left and right ends of the inner circumference of the heating tube 101 are connected with fixing rods 102 by screws, the heating wire 103 is clamped between the heating tube 101 and the fixing rods 102, the heating wire 103 can generate heat, and the heating tube 101 prevents the heat of the heating wire 103 from dissipating. The two fixing rods 102 can stably set the heating wire 103 on the inner side of the heating tube 101, and the metal part can be heated by putting it into the heating tube 101.

[0027] like Figure 4-7 As shown, this example can achieve the effect of allowing the metal part to enter the heating tube 101 for heating.

[0028] Since the rear side of the heating cylinder 101 is welded with a rear frame 105, and the upper side of the rear frame 105 is welded with a column 104, the rear part of the cross bar 201 is vertically slidably connected to the column 104, and the cross bar 201 is driven to rise and fall by a hydraulic cylinder. The front and rear ends of the cross bar 201 are slidably connected with clips 209, and the clips 209 are driven to slide by a hydraulic cylinder. A plurality of ridges 210 are provided on the opposite surfaces of the two clips 209; a plurality of through holes 211 are provided on the opposite surfaces of the two clips 209, and the cross bar 201 can slide vertically on the column 104, thereby driving the two clips 209 to rise and fall. After the two clips 209 approach each other to clamp the metal parts, the cross bar 201 and the two clips 209 are driven to slide downward, thereby allowing the metal parts to enter the heating cylinder 101 for heating. The plurality of ridges 210 can play an anti-slip role when clamping a metal piece, and the plurality of through holes 211 can prevent the clip 209 from excessively shielding the metal piece, thereby avoiding affecting the heating of the metal piece.

[0029] like Figure 6-7 As shown, this example can achieve the effect of driving the metal piece to eject downward quickly by the pressure head 208.

[0030] Since the middle part of the cross bar 201 is a hollow structure, two support columns 202 are welded on the upper side of the middle part of the cross bar 201, and a disc 203 is welded on the upper ends of the two support columns 202. A spring rod 204 is vertically slidably connected to the disc 203, and a pressure head 208 is welded at the lower end of the spring rod 204. A stopper 205 is welded at the upper end of the spring rod 204. A compression spring is sleeved on the spring rod 204, and the compression spring is located between the disc 203 and the pressure head 208, so that the pressure head 208 can be pressed against the upper side of the metal part. When the two clips 209 are loosened, the spring on the spring rod 204 drives the pressure head 208 to move downward quickly, and then drives the metal part to eject downward quickly through the pressure head 208.

[0031] like Figure 6-7 As shown, this example can achieve the effect of applying elastic force to the metal part through the pressing head 208.

[0032] Since a side strip 206 is welded to the right side of the disc 203, an L-shaped rod 207 is connected to the side strip 206 for transverse sliding. The L-shaped rod 207 blocks the lower side of the pressure head 208. The L-shaped rod 207 is driven to slide by a hydraulic cylinder. When the pressure head 208 is not needed to press against the upper side of the metal part, the L-shaped rod 207 is driven to slide to the left on the side strip 206, so that the L-shaped rod 207 blocks the lower side of the pressure head 208, thereby preventing the pressure head 208 from moving downward. When the pressure head 208 needs to press against the upper side of the metal part, the L-shaped rod 207 is driven to move to the right on the side strip 206, so that the L-shaped rod 207 leaves the pressure head 208. At this time, the lock on the pressure head 208 is released, so that the pressure head 208 is pressed on the upper side of the metal part, and an elastic force is applied to the metal part through the pressure head 208.

[0033] like Figure 4-9 As shown, this example can achieve the effect of metal parts being able to bounce into the cooling medium and cool quickly.

[0034] Since the lower end of the rear frame 105 is connected to the rear side of the rectangular box 301 by screws, a flat plate 302 is welded to the middle of the inner side of the rectangular box 301, and a circular hole 307 is provided at the center of the flat plate 302. A container is formed by the flat plate 302 and the rectangular box 301, and a cooling medium is placed in the container. Metal parts can be ejected into the cooling medium for rapid cooling.

[0035] like Figure 8-9 As shown, this example can achieve the effect of supporting the rectangular box 301 through four legs 303 .

[0036] Since legs 303 are welded at the four corners of the lower part of the rectangular box 301, the rectangular box 301 is supported by the four legs 303.

[0037] like Figure 8-9 As shown, this example can achieve the effect of conveniently taking out the metal parts from the rectangular box 301 .

[0038] Since the lower part of the rectangular box 301 is vertically slidably connected with the piston plate 304, two vertical columns 305 are welded on the lower side of the piston plate 304, and convex plates 306 are welded on the left and right ends of the lower side of the rectangular box 301. The two vertical columns 305 are respectively connected to the two convex plates 306 in a vertical sliding manner. The vertical columns 305 are driven to slide by a hydraulic cylinder, and a sealing strip is provided at the edge of the piston plate 304. The two vertical columns 305 can be lifted and slid on the two convex plates 306 respectively, so that the piston plate 304 slides vertically at the lower part of the rectangular box 301, and then the cooling medium on the upper side of the flat plate 302 in the rectangular box 301 enters the lower side of the flat plate 302 through the circular hole 307 through the lifting of the piston plate 304, so that the liquid level of the cooling medium in the rectangular box 301 drops, so that it is convenient to take out the metal parts from the rectangular box 301.

[0039] like Figure 8-9 As shown, this example can achieve the effect of rapidly cooling the metal part in the cooling medium.

[0040] Since support bars 407 are welded to the left and right ends of the upper side of the flat plate 302, side shafts 408 are fixed to the left and right ends of the receiving basket 401, and the two side shafts 408 are respectively rotatably connected to the upper parts of the two support bars 407, multiple leak holes 402 are arranged on the receiving basket 401 from left to right, and convex plates 403 are fixed to the front and rear ends of the inner side of the receiving basket 401. After the metal parts are ejected into the cooling medium, they enter the receiving basket 401. The receiving basket 401 can swing back and forth between the two support bars 407 through the two side shafts 408, thereby making the metal parts in the receiving basket 401 swing back and forth in the cooling medium, thereby making the metal parts quickly cool in the cooling medium. Multiple leak holes 402 can facilitate the cooling medium to enter and exit the receiving basket 401, and the convex plates 403 can block the metal parts in the receiving basket 401 to prevent the metal parts from being thrown out of the receiving basket 401.

[0041] like Figure 8-9 As shown, this example can achieve the effect of driving the receiving basket 401 to swing back and forth between the two support bars 407 through the two side shafts 408.

[0042] Since a slot rod 406 is welded to one of the side shafts 408, a seat plate 409 is welded to the upper part of the rectangular box 301, and a lifting column 404 is vertically slidably connected to the seat plate 409, and a round rod 405 is welded to the lifting column 404, and the round rod 405 is inserted into the linear groove on the slot rod 406. The lifting column 404 is driven to slide by a hydraulic cylinder, which can drive the lifting column 404 to rise and fall and slide on the seat plate 409, thereby driving the round rod 405 to rise and fall and slide, and further driving the receiving basket 401 to swing back and forth between the two support bars 407 through the two side shafts 408.

[0047] S4: Take the cooled metal part out of the cooling medium.
