Technical Field
[0001] This utility model relates to the field of bar stock feeding, specifically a batch heat treatment bar stock feeding device. Background Technology
[0002] In the heat treatment industry, batch feeding of bar stock has always been a critical step. Current feeding methods often rely on manual operation, which leads to problems such as unstable feeding, low efficiency, and significant safety hazards. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, this utility model provides a batch heat treatment bar feeding device.
[0004] The technical solution adopted by this utility model is as follows:
[0005] A batch heat treatment bar feeding device includes a furnace inlet with an opening at the top. Two furnace inlets are distributed front to back. Slide rails are fixedly connected to the top right side walls of both furnace inlets. The slide rails extend to the right and are symmetrical. The cross-section of the slide rails is semi-circular. The left end of the slide rails passes through the right side wall of the furnace inlet. A feeding pipe is fixedly connected to the top center of both slide rails. The feeding pipe is rectangular in shape. The bottom of the left and right side walls of the feeding pipe are semi-circularly arched upwards. A hopper is fixedly connected to the top of the feeding pipe. The bottom of the hopper is connected to both ends of the top of the feeding pipe. A cylinder is installed between the two slide rails. The piston rod of the cylinder extends to the right. The end of the piston rod is fixedly connected to the middle of a connecting plate. Push rods are vertically fixed to the front and rear ends of the left side wall of the connecting plate. The push rods pass through the bottom of the feeding pipe. There is a gap between the outer wall of the push rod and the bottom of the feeding pipe. The outer wall of the push rod slides in conjunction with the slide rail.

[0016] like Figure 1-5 As shown: A batch heat treatment bar feeding device includes a furnace inlet 1 with an opening at the top. Two furnace inlets 1 are distributed front to back. A slide rail 2 is fixedly connected to the top right side wall of each of the two furnace inlets 1, extending to the right. The two slide rails 2 are symmetrical front to back, and their cross-sections are semi-circular. The left end of each slide rail 2 penetrates the right side wall of the furnace inlet 1. A discharge pipe 5 is fixedly connected to the top center of each of the two slide rails 2. The discharge pipe 5 is rectangular in shape, and the bottom of both its left and right side walls are semi-circular upwards. The top of the feeding pipe 5 is fixedly connected to the hopper 6, and the bottom of the hopper 6 is connected to both ends of the top of the feeding pipe 5. A cylinder 7 is set between the two slide rails 2. The cylinder barrel of the cylinder 7 is fixed to the outer wall of the feed inlet 1. The piston rod of the cylinder 7 extends to the right and the end of the piston rod of the cylinder 7 is fixedly connected to the middle of the connecting plate 8. The front and rear ends of the left side wall of the connecting plate 8 are vertically fixedly connected to the push rod 9. The push rod 9 passes through the bottom of the feeding pipe 5. There is a gap between the outer wall of the push rod 9 and the bottom of the feeding pipe 5. The outer wall of the push rod 9 slides in cooperation with the slide rail 2.
[0017] The furnace door 3 is rotatably connected to the top of the rear side wall of the furnace inlet 1. The sealing block 4 is fixedly connected to the right end of the furnace door 3. The sealing block 4 is semi-circular and fits against the top of the left end of the slide rail 2.
[0018] The bar stock 10 that needs to be heat treated is neatly arranged in the hopper 6. Since the bottom of the hopper 6 is connected to the top of the discharge pipe 5, the bar stock 10 will move downward along the discharge pipe 5 under the action of gravity. The length of the pipe 5 is slightly greater than the length of the bar stock 10, and the thickness of the pipe 5 is slightly greater than the thickness of the bar stock 10. The bar stock 10 is cylindrical. The shape and thickness of the bar stock 10 and the push rod 9 are the same. The length of the push rod 9 is greater than the length of the bar stock 10.
[0019] When the bar stock moves to the bottom of the feed pipe 5, it will stay there temporarily, waiting to be pushed by the push rod 9.
[0020] When cylinder 7 starts working, its cylinder column retracts to the left, causing connecting plate 8 to move to the left. Since push rod 9 is vertically fixed at both the front and rear ends of the left side wall of connecting plate 8, push rod 9 will also move to the left.
[0021] There is a gap between the outer wall of the push rod 9 and the bottom of the feeding pipe 5, which allows the push rod 9 to push the bar that has fallen to the bottom without interfering with the falling of the bar. At the same time, the outer wall of the push rod 9 slides in conjunction with the slide rail 2 to ensure that the push rod 9 remains stable and guided during movement.
[0022] When push rod 9 moves to the position of the bar stock, it pushes the bar stock along slide rail 2 into the furnace feed port 1. The cross-section of slide rail 2 is semi-circular, which helps the bar stock maintain smooth and directional movement during the pushing process.
[0023] After the bar stock is pushed into the furnace feed inlet 1, the bottom of the feed inlet 1 is connected to the furnace. The furnace is an existing technology device, and its specific structural features will not be described further. The furnace door 3 will be closed, and the sealing block 4 will fit against the top of the left end of the slide rail 2 to ensure that the heat inside the furnace feed inlet 1 will not leak.
[0024] The bottom of the furnace feed inlet 1 is connected to a heat treatment furnace, which heat-treats the bar stock.
[0025] After one batch of bar stock is processed, cylinder 7 will operate again, pulling connecting plate 8 and push rod 9 back to their original positions, ready for the next batch of bar stock to be fed. This utility model only protects the mechanical parts; functions implemented through software control are not within the scope of protection of this utility model.
