Description

Technical Field

[0001] This utility model relates to the field of handrail processing technology, specifically a heating and bending device for stair handrails. Background Technology

[0002] Most furniture and stair railings are made of solid wood. Solid wood bending refers to a method of bending wood into shape through softening and pressure treatment. Curved parts produced using this method have natural, smooth lines, beautiful shapes, good strength, save labor and materials, and retain the rich natural texture and color of the wood, thus making it widely used in actual production. Wood is elastic; within a normal stress range, wood can bend and returns to its original shape when the stress is removed. If the stress limit is exceeded, permanent deformation and fiber splitting occur. A common method for bending wood with a small radius involves heating the wood to change its fiber properties, increasing its elasticity, and then immediately fixing it in a clamp until the fibers cool and dry to set the shape.

[0003] Currently, existing stair handrail bending devices require workers to heat the boards using other equipment before placing them into the bending device for manual bending, which affects the processing efficiency of stair handrails. Therefore, a stair handrail heating and bending device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a stair handrail heating and bending device to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stair handrail heating and bending device, including a processing table, on which a bending mechanism is provided;

[0006] The bending mechanism includes a motor and a fixed cylinder. A first rotating shaft is fixedly connected to the output end of the motor. A bearing is fixedly connected inside the fixed cylinder. The first rotating shaft is fixedly connected to the inner wall of the inner ring of the bearing. A connecting frame is fixedly connected to the first rotating shaft. A bending plate is fixedly connected to the fixed cylinder. A bending plate is fixedly connected to the connecting frame. A heating cylinder is fixedly connected to the processing table. An electric heating coil is fixedly connected inside the heating cylinder.

[0007] Preferably, the motor is fixedly connected to the bottom of the processing table, and the fixed cylinder is fixedly connected to the upper surface of the processing table. By starting the motor, the first rotating shaft can be driven to rotate, causing the bending plate to rotate.

[0008] Preferably, the heating cylinder has an inlet at its left end and an outlet at its right end, thus allowing the wood to be heated.

[0009] Preferably, the bottom of the processing table is fixedly connected to a support frame, and there are two support frames. The two support frames are respectively fixedly connected to the front end and the rear end of the bottom of the processing table, and the support frames can support the processing table.

[0010] Preferably, the processing table is provided with a guiding mechanism, which includes a second rotating shaft. The second rotating shaft is rotatably connected to the processing table through a bearing. The guiding mechanism can limit and guide the wood.

[0011] Preferably, a first guide wheel is fixedly connected to the second rotating shaft, and a second guide wheel is rotatably connected to the processing table via a bearing. The guide wheel arrangement can prevent the plate from shifting position.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This stair handrail heating and bending device involves inserting one end of a piece of wood into the heating cylinder, activating the electric heating coil to heat the wood, then pushing the heated wood out and inserting it between the bending plate and the folding plate. The motor is then activated to drive the first rotating shaft to rotate, which in turn drives the connecting frame to rotate. At this time, the folding plate will rotate and bend the heated section of the wood, achieving integrated heating and bending. This eliminates the need for manual bending and improves the bending efficiency of stair handrails.

[0014] 2. This stair handrail heating and bending device, by setting a first guide wheel and a second guide wheel, can guide and limit the wood, avoiding the problem of the wood shifting position during movement, thereby improving the accuracy of the wood bending and further improving the practicality of the heating and bending device.

[0024] Please see Figure 1-4 One embodiment of this utility model is: a stair handrail heating and bending device, including a processing table 1, on which a bending mechanism 2 is provided;

[0025] The bending mechanism 2 includes a motor 201 and a fixed cylinder 202. A first rotating shaft 204 is fixedly connected to the output end of the motor 201. A bearing 203 is fixedly connected inside the fixed cylinder 202. The first rotating shaft 204 is fixedly connected to the inner wall of the inner ring of the bearing 203. A connecting frame 206 is fixedly connected to the first rotating shaft 204. A bending plate 205 is fixedly connected to the fixed cylinder 202. A bending plate 207 is fixedly connected to the connecting frame 206. A heating cylinder 208 is fixedly connected to the processing table 1. An electric heating plate is fixedly connected inside the heating cylinder 208. The heating coil 209 heats the wood by inserting one end of the wood into the heating cylinder 208. The heated wood is then pushed out and inserted between the bending plate 205 and the bending plate 207. The motor 201 is then started to drive the first rotating shaft 204 to rotate, which in turn drives the connecting frame 206 to rotate. At this time, the bending plate 207 will rotate and bend the heated section of the wood, realizing integrated heating and bending. This eliminates the need for manual bending and improves the bending efficiency of the stair handrail.

[0026] The motor 201 is fixedly connected to the bottom of the processing table 1, and the fixed cylinder 202 is fixedly connected to the upper surface of the processing table 1. By starting the motor 201, the first rotating shaft 204 can be driven to rotate, causing the bending plate 207 to rotate.

[0027] The heating cylinder 208 has an inlet 210 at the left end and an outlet 211 at the right end, which allows the wood to be heated.

[0028] The bottom of the processing table 1 is fixedly connected to a support frame 4. There are two support frames 4, which are fixedly connected to the front end and the rear end of the bottom of the processing table 1, respectively. The support frames 4 can support the processing table 1.

[0029] Working principle: By inserting one end of the wood into the heating cylinder 208, the electric heating coil 209 is activated to heat the wood. Then, the heated wood is pushed out and inserted between the bending plate 205 and the bending plate 207. Then, the motor 201 is activated to drive the first rotating shaft 204 to rotate, which in turn drives the connecting frame 206 to rotate. At this time, the bending plate 207 will rotate and bend the heated section of the wood, realizing integrated heating and bending. No manual bending is required, which improves the bending efficiency of stair handrails.

[0030] Please see Figure 1-4 Based on the above embodiments, in another embodiment of the present invention, a guide mechanism 3 is provided on the processing table 1.
