Abstract
Description
Technical Field
[0001] The invention relates to the technical field of polytetrafluoroethylene-lined pipe fittings, in particular to a sintering furnace for processing polytetrafluoroethylene-lined pipe fittings. Background Art
[0002] The sintering process is an important step in the production of PTFE lined pipe fittings. Sintering refers to heating the PTFE material at high temperature to improve the mechanical strength and heat resistance of the pipe fittings and ensure their stability and durability during use.
[0003] Although the existing sintering furnace can complete the sintering process of PTFE-lined pipe fittings, there are still some obvious defects in actual operation. First, the furnace body of the traditional sintering furnace is usually designed to be low, and the sintering bed is located at the bottom of the furnace body. After it is taken out of the furnace, the height of the sintering bed is low, and the staff needs to bend or squat to take out the high-temperature pipe fittings. This operation method is easy to cause the operator to be scalded due to improper posture or accidentally touching the high-temperature sintering bed. Secondly, the existing equipment lacks a stable support mechanism after the sintering bed is taken out of the furnace. The sintering bed is prone to shaking during movement. The sintering bed that can be fixedly supported is heavy, so the flexibility of movement will be limited. Therefore, after taking out the sintering bed, the traditional sintering furnace is very inconvenient and dangerous to take out the parts.
[0004] Therefore, a sintering furnace for processing polytetrafluoroethylene lined pipe fittings is urgently needed to solve the technical defects proposed in the above-mentioned technology. Summary of the invention
[0005] The object of the present invention is to provide a sintering furnace for processing polytetrafluoroethylene lined pipe fittings, so as to solve the problem in the above background technology that after taking out the sintering bed, it is very inconvenient and dangerous to take out the parts.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a sintering furnace for processing polytetrafluoroethylene lined pipe fittings, comprising a furnace body and a mounting seat, a base is arranged at the right side of the furnace body near the furnace door, two groups of mounting seats are fixedly connected in the base, two groups of bottom columns are movably connected in each group of mounting seats, racks are fixedly sleeved on the bottom columns, a motor slot is opened at the bottom end of the bottom column, a lifting motor is installed in the motor slot, the output shaft of the lifting motor is fixedly connected with a first gear, the top of the first gear is fixedly connected with a second gear, the first gear and the rack are respectively meshed and connected, a rotating shaft is arranged on one side of the mounting seat, the rotating shaft is movably assembled in the base, a support plate is sleeved on the outside of the rotating shaft, a fourth gear is arranged between the two groups of support plates, a connecting shaft is arranged between the fourth gear and the first gear, a scissors frame is arranged on the top of the bottom column, a furnace car is fixedly connected to the top of the scissors frame, and a sintering bed is arranged above the furnace car.
[0007] Preferably, the scissors frame is in an "X" shape, and grooves for the bottom column to move are provided at both ends of the inner wall of the mounting seat.
[0008] Preferably, two groups of stoppers are welded to the bottom end of the sintering bed, and the support plates are in contact with the stoppers in a vertical state.
[0009] Preferably, four groups of support plates are provided in total, and the length of the support plates is equal to the vertical distance from the bottom end of the sintering bed to the base.
[0010] Preferably, a winding seat is provided on the right side of the base, a metal rope is wound on the winding seat, and an iron hook is installed on the right side of the bottom end of the sintering bed.
[0011] Preferably, the metal rope is hung and fixed with an iron hook, and a winding motor is installed at the front end of the winding seat.
[0012] Preferably, a handle is installed on the edge of the sintering bed, rollers are installed at both ends of the bottom of the sintering bed, guide rods are installed at both ends of the furnace car, and the rollers and the guide rods form a rolling connection.
[0013] Preferably, the rollers are arranged in five groups, and the rollers are evenly spaced at the bottom of the sintering bed.
[0014] Preferably, a plurality of pipes are arranged in the sintering bed, and each group of pipes is placed at equal intervals.
[0015] Preferably, third gears are fixedly sleeved on both sides of the sintering bed, and the third gears are meshed and connected with the first gear and the fourth gear respectively.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: by arranging a furnace body, a sintering bed, pipe fittings, handles, an iron hook, a metal rope, a winding motor, a winding seat, a furnace car, a base, a guide rod, a block, a lifting motor, a mounting seat, a scissors frame, a motor slot, a roller, a first gear, a rack, a bottom column, a second gear, a fourth gear, a rotating shaft, a connecting shaft, a third gear, and a support plate, after sintering is completed, the metal rope is hung on the bottom end of the iron hook, and the winding motor is started. Under the pull of the metal rope, the sintering bed comes to the furnace car, and the smooth movement of the sintering bed is ensured by the rolling of multiple groups of rollers at the guide rod.

At this time, the support plate flips from a horizontal state to a vertical state and presses against the bottom end of the sintering bed to provide support for the sintering bed. Two sets of blocks press against the support plate to ensure the stability of the support force. At this time, the scissors frame has also moved to the maximum lifting angle, realizing the automatic lifting of the sintering bed while providing the sintering bed with a flippable support force at the bottom, which is convenient for the staff to remove the pipe fittings and prevents the staff from touching the high-temperature sintering bed and getting burned due to careless operation when bending over to remove the high-temperature pipe fittings. It also improves the safety of cooling, ensures the flexibility of the sintering bed movement and the stability after shutdown. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, after sintering is completed, the metal rope 6 is hung to the bottom end of the iron hook 5, and the winding motor 7 is started. Under the pulling of the metal rope 6, the sintering bed 2 comes to the furnace car 9, and the smooth movement of the sintering bed 2 is ensured by the rolling of multiple groups of rollers 17 at the guide rod 11. When the sintering bed 2 moves to the top of the furnace car 9, the winding motor 7 stops rotating, and the lifting motor 13 is started at this time. The lifting motor 13 drives the first gear 18 to rotate, thereby driving the two groups of racks 19 to move relative to each other, and the bottom column 20 moves relative to each other, and the scissors frame 15 changes its angle accordingly to support the furnace car 9 upward, so that the sintering bed 2 is lifted as a whole from a lower position.

[0029] Working principle: After sintering is completed, the metal rope 6 is hung to the bottom end of the iron hook 5, and the winding motor 7 is started. Under the pull of the metal rope 6, the sintering bed 2 comes to the furnace car 9, and the smooth movement of the sintering bed 2 is ensured by the rolling of multiple groups of rollers 17 at the guide rod 11. When the sintering bed 2 moves to the top of the furnace car 9, the winding motor 7 stops rotating, and the lifting motor 13 is started at this time. The lifting motor 13 drives the first gear 18 to rotate, thereby driving the two groups of racks 19 to move relative to each other, and the bottom column 20 moves relative to each other, and the scissors frame 15 changes its angle accordingly to support the furnace car 9 upward, so that the sintering bed 2 is lifted as a whole from a lower position.

The two sets of blocks 12 abut against the support plate 26 to ensure the stability of the support force. At this time, the scissors frame 15 has also moved to the maximum lifting angle, realizing automatic lifting of the sintering bed 2 while providing a bottom flip support force for the sintering bed 2, which is convenient for the staff to take out the pipe fittings 3 and prevents the staff from touching the high-temperature sintering bed 2 and getting burned due to careless operation when bending over to take out the high-temperature pipe fittings 3.
