[0021] An upper end sealing door 4 is fixed on one end of the heating furnace cover 13 near the two supporting inclined plates 6, a rectangular feeding port one is arranged in the middle of the upper end sealing door 4 and at the junction of the supporting inclined plates 6 and the ramp conveying frame 2, a rectangular discharge port two is reserved above the two ramp conveying frames 2 at the discharge port of the heating furnace cover 13, and a plurality of chains are arranged above the rectangular discharge port two, since a plurality of chains arranged side by side are arranged, not only can a part of heat be blocked from being dissipated, but also the impurities on the surface of the copper bar body 22 after heating can be removed.

[0022] With reference to Figure 1 and Figure 3The lower surfaces of the front and rear ends of the cantilever beam are respectively fixed with mutually symmetrical fixed pulley sets 12, and the fixed pulley sets 12 are provided with fixed pulleys with the same diameter, the front and rear ends of the inclined pressing plate 7 are provided with extension strips, and the sides of the two extension strips away from the heating furnace cover 13 are respectively fixed with vertical arc-shaped guide plates 701, the two arc-shaped guide plates 701 are respectively slidably connected with counterweight slide columns 8, and the upper and lower ends of the counterweight slide column 8 are respectively fixed with a steel wire rope 9 and a steel drill rod 801, the sides of the two support inclined plates 6 away from each other are respectively fixed with a limiting clamping frame 5 with a diameter matched with the steel drill rod 801 below the corresponding counterweight slide column 8, and the steel wire rope 9 is fixed on the upper surface of the extension strip on the side through the fixed pulley at the top thereof.

[0023] With reference to Figure 1 and Figure 3 , the side of the circumferential outer wall of the counterweight slide column 8 close to the arc-shaped guide plate 701 is reserved with an anti-slip block, and the groove bottom of the arc-shaped guide plate 701 is provided with a vertically extending strip-shaped sliding hole, the anti-slip block is slidably inserted into the corresponding strip-shaped sliding hole, so that the counterweight slide column 8 and the steel drill rod 801 can vertically descend even if they are extruded from the copper bar body 22 above, and then are smoothly inserted into the corresponding limiting clamping frame 5 to form effective interception.

[0024] With reference to Figures 1-2 , the inside of the heating furnace cover 13 is provided with a three-section heating cavity, and the front of the heating furnace cover 13 close to the discharge port and one end of the support inclined plate 6 are provided with observation windows 15, and the observation windows 15 are provided with devices that can observe the internal operation, so that the running condition of the copper bar body 22 on the slope conveying frame 2 can be observed in real time, so as to adjust the rhythm of feeding and discharging.

[0025] With reference to Figures 4-6 , the overall shape of the slope conveying frame 2 is a right-angled triangular plate structure, and the slope surface of the slope conveying frame 2 is a wave-shaped structure, and the wave crests and wave troughs are straight sections. Since the slope surface is provided with a wave-shaped structure, when the copper bar body 22 rolls forward, it avoids being in contact with the slope surface at all times, which causes uneven heating and then causes the internal crystal grains and performance to differ too much.

[0026] With reference to Figure 1 and Figure 4The minimum distance between the two ramp conveying frames 2 is equal to the distance between the two supporting inclined plates 6, and the maximum distance between the two ramp conveying frames 2 is less than the length of the copper bar body 22, and the front and rear sides of the heating furnace cover 13 are provided with abutting rods near the running track of the copper bar body 22, so as to ensure that the axial deviation of the copper bar body 22 is not too large and always falls on the two ramp conveying frames 2 to roll.

[0027] With reference to Figures 4-8 The inclined surfaces of the ramp conveying frames 2 are provided with combined sliding grooves 201 at the wave crests and wave troughs, and the combined sliding grooves 201 include cylindrical grooves and rectangular grooves that are partially overlapped together. The groove bottoms of the rectangular grooves are provided with through holes 202 that pass through the bottom plate 16 below. The discharging pull rods 21 are slidingly inserted into the through holes 202. The top ends of the discharging pull rods 21 are fixedly connected with the limiting sliding insertion plates 14. The limiting sliding insertion plates 14 are provided with arc-shaped notches near the feeding end for blocking the copper bar body 22. Since the limiting sliding insertion plates 14 that are slidingly connected in the combined sliding grooves 201 can slide up and down, the adjacent two copper bar bodies 22 can be separated, so as to ensure that the adjacent two copper bar bodies 22 always maintain a parallel state during heating, so that the heating is uniform. When it is needed to advance the copper bar body 22, the discharging pull rods 21 are only pulled downward, so that the limiting sliding insertion plates 14 are entirely retracted into the combined sliding grooves 201.

[0028] With reference to Figures 4-8 The bottom ends of the discharging pull rods 21 are fixedly connected with the double-head slats 20. The upper surfaces of the double-head slats 20 are fixedly connected with the return tension springs 19 and the wear-resistant cross bars at the front and rear ends of the discharging pull rods 21. The lower surfaces of the bottom plate 16 are fixedly connected with the bearing hangers 24 at the two ends of the ramp conveying frames 2. A same transmission rod is slidingly inserted between the two bearing hangers 24. The outer wall of the transmission rod is fixedly connected with the sawtooth pull rods 3 that are vertically arranged on the plate surface. The sawtooth pull rods 3 are located between the adjacent two discharging pull rods 21. The fluctuation amplitude of the sawtooth pull rods 3 is greater than the groove depth of the combined sliding grooves 201, so that when the sawtooth pull rods 3 axially move, the discharging pull rods 21 can be pulled downward to move downward. The supporting frame 1 near the discharging port is provided with the hydraulic jacks 17. The end portions of the extension rods of the hydraulic jacks 17 are fixedly connected with the same U-shaped connecting rods 18. The two ends of the U-shaped connecting rods 18 are fixedly connected with the end portions of the two discharging pull rods 21, so as to simultaneously and synchronously control the limiting sliding insertion plates 14 on the inclined surfaces of the two ramp conveying frames 2 to rise or retract.

[0029] With reference to Figure 7The top opening of the cylindrical groove is fixed with a wear-resistant sliding ring 23, and a downward extending auxiliary ejector rod 25 is slidingly inserted into the wear-resistant sliding ring 23, the circumferential outer wall of the auxiliary ejector rod 25 is fixed with a spring retainer ring near the middle part, a compression spring is fixed between the top end of the spring retainer ring and the lower surface of the wear-resistant sliding ring 23, and the hinged part of the groove bottom of the cylindrical groove and the rectangular groove is hinged with a rocker 26; when the limiting sliding plate 14 is completely lowered, the auxiliary ejector rod 25 is arranged to drive the other end of the rocker 26 to rise, thereby pushing the originally static copper bar body 22, and preventing the copper bar body 22 from being stuck in the original position.

[0030] Working principle: when the device is used, a plurality of copper bar bodies 22 are arranged in order on the inclined surfaces of the two supporting inclined plates 6, and are pressed and positioned by the inclined pressing plate 7; when feeding and heating are needed, the inclined pressing plate 7 and the convex ridge rod at the end thereof are lifted to a preset lifting height and rhythm; at this time, the copper bar body 22 closest to the bottom is released, and at the same time, the counterweight slide column 8 and the steel spike insertion rod 801 arranged synchronously and reversely with the inclined pressing plate 7 are operated; when the inclined pressing plate 7 is lifted to release the copper bar body 22 closest to the heating furnace cover 13, the steel spike insertion rod 801 is lowered and inserted into the corresponding limiting clamping frame 5, so as to block the next copper bar body 22, and ensure that only one copper bar body 22 is fed each time; the released copper bar body 22 continues to roll into the heating furnace, reaches the two slope conveying frames 2 and is blocked by the two highest limiting sliding plates 14, and is heated for a set time; during the set time, the extension rod of the electric push rod 10 is retracted to the initial position, the steel spike insertion rod 801 is pulled out, the second copper bar body 22 is blocked and reaches the position before the first copper bar body 22 is released, i.e. the obliquely upward position of the convex ridge rod, for the next release, and the automatic following is performed. Then, the hydraulic ejector rod 17 at the bottom of the device is controlled to start at a predetermined rhythm, and the two limiting sliding plates 14 are pulled down quickly; at this time, the first copper bar body 22 rolls down one station, and at the same time, the blanking and releasing action is performed again, so that the feeding and discharging can be realized in cycles.

[0031] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
