[0011] The present utility model will be further described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0012] As Figure 1 , Figure 2As shown in the figure, the workpiece feeding and heating tooling includes: two ground rails 1 arranged on the ground and respectively butt-jointed with two rails in the heating furnace 15. The two ground rails 1 are arranged in the front-back direction. Two roller frames 2 are arranged on each ground rail 1. Two rollers 3 arranged front and back and capable of rolling on the ground rail are arranged on each roller frame 2. Each roller frame 2 can move back and forth by rolling on the ground rail 1 through the two rollers 3 thereon. The two roller frames 2 located in the front are aligned left and right and are connected and fixed by a rod to form a front sliding frame 4. The two roller frames 2 located in the back are aligned left and right and are connected and fixed by a rod to form a rear sliding frame 5. Two connecting rods 6 are respectively located on the left and right sides of the front sliding frame 4 and the rear sliding frame 5. The two sides of the two sliding frames are respectively detachably connected to the connecting rod 6 on the corresponding side by pins. A plurality of pin holes are arranged on the connecting rod 6, so that the position where the sliding frame and the connecting rod 6 are pinned can be adjusted, and thus the front-back distance between the front sliding frame 4 and the rear sliding frame 5 can be adjusted. A vertical socket is arranged on each roller frame 2. Each roller frame 2 is equipped with a long column 7. The lower end of each long column 7 is provided with a plug-in section. Each long column 7 can be inserted into the vertical socket through the plug-in section at its lower end and is inserted and installed on the corresponding roller frame 2. Three cross bars 8 are successively arranged at intervals from bottom to top on the outer sides of the left and right sides of each long column 7. A limiting edge 9 is arranged on the upper surface of each cross bar 8. Three clamping joints 10 are successively arranged at intervals from bottom to top on the inner sides of the left and right sides of each long column 7. A plurality of cross beams 11 and a plurality of longitudinal beams 12 are also arranged. The longitudinal beam 12 can be placed on two cross bars 8 aligned front and back, so that the longitudinal beam 12 can be used to support the workpiece. The longitudinal beam 12 is limited left and right by the limiting edge 9. Clamping columns are arranged at both ends of the cross beam 11. Both ends of the cross beam 11 can be respectively clamped on two relatively left and right clamping joints 10, so that the cross beam 11 can be used to support the workpiece. The longitudinal beam 12 can also be placed on the cross beam 11. The clamping joint 10 is composed of two clamping plates arranged side by side. Slots are respectively arranged on the clamping plates. When the cross beam 11 is clamped, the clamping columns are inserted into the slots. The frame composed of the front sliding frame 4, the rear sliding frame 5, the connecting rod 6, the long column 7, the cross beam 11, the longitudinal beam 12 and the workpiece placed thereon can be driven to move along the ground rail 1 into the heating furnace 15. The placement positions and quantities of the cross beam 11 and the longitudinal beam 12 can be changed in real time to adapt to workpieces of different specifications.

[0013] In this embodiment, there are also provided a pulley 13 and a winch 14. The pulley 13 is installed in the middle of the entrance of the heating furnace 15. In the middle of the rear part of the rear sliding frame 5, there is a push-pull rod 16 placed horizontally. The front end of the push-pull rod 16 is hinged to the rear sliding frame 5. The push-pull rod 16 can be manually swung upward to lean against the rear sliding frame 5. The winch 14 is located behind the rear sliding frame 5. The steel wire rope on the winch 14 can be wound around the pulley 13 and can be hooked to the rear end of the push-pull rod 16 through a hook. When the winch 14 winds up the steel wire rope, under the pulling of the steel wire rope, the frame composed of the front sliding frame 4, the rear sliding frame 5, the connecting rod 6, the long upright column 7, the cross beam 11, and the longitudinal beam 12 and the workpieces placed thereon can be pulled into the heating furnace 15 along the ground rail 1. Then, after the push-pull rod 16 is driven to stand up, it can not hinder the closing of the furnace door of the heating furnace 15. With such a setting, the labor intensity of workers can be greatly reduced.

[0014] On both sides of the push-pull rod 16, there is respectively a chain. One end of each chain is connected to the rear sliding frame 5, and the other end of each chain is connected to the push-pull rod 16, so that when the push-pull rod 16 lies flat, it can be obliquely pulled and supported by the two chains. Such a setting is to prevent the push-pull rod 16 from being pulled and deformed.

[0015] Each roller rack 2 is also equipped with a short upright column 17. The lower end of each short upright column 17 is also provided with a plug-in section. Each short upright column 17 can be inserted onto the top of the corresponding long upright column 7 through the plug-in section at its lower end. On the outer sides of the left and right sides of each short upright column 17, there is a cross bar 8, and on the inner sides of the left and right sides of each short upright column 17, there is a clamping head 10. With such a setting, more workpieces can be placed on the frame.
