Description

Technical Field

[0001] This utility model belongs to the field of elastic bar production technology, and in particular relates to an elastic bar feeding device. Background Technology

[0002] Elastic bars are made of materials such as steel bars that have been heat-treated and then twisted into different shapes according to their intended use, and are used as connecting parts. For example, E-shaped elastic bars are often used as connecting parts on train tracks.

[0003] During the production and processing of spring clips, the bar stock for producing spring clips needs to be pushed into the furnace for heat treatment. After heat treatment, the bar stock at high temperature can not only be easily processed into spring clip connectors of specific shapes, but heat treatment can also increase the material properties such as hardness.

[0004] Since different types of spring clip connectors have different uses, the diameter (thickness) of the spring clip rods used is different. Therefore, during the production process, depending on the needs of the products being processed, it is often necessary to push spring clip rods of different diameters into the furnace body, specifically from the feed port of the furnace body.

[0005] Currently, the workshop uses a chain-based feeding method for the bar stock. This involves installing baffles on the chain, and the chain rotation feeds the bar stock into the heating furnace. The spacing of the chain baffles is determined based on the length and diameter of the bar stock. Therefore, in actual production, if the diameter of the bar stock changes (for processing different product models), a different type of chain needs to be used.

[0006] Meanwhile, since the position of the chain is fixed, when the diameter of the bar stock changes, the bar stock will no longer be aligned with the furnace feed port. The disadvantage of the chain feeding method is that it is difficult to correct the position of the chain and align the bar stock loaded on the chain with the furnace feed port.

[0041] Example 1

[0042] like Figure 1-6 As shown, a spring bar feeding device includes a feeding mechanism 3. The feeding mechanism 3 includes a horizontal pushing component for horizontally pushing bar stock 2 into a heating furnace 2. The feeding mechanism 3 also includes a transverse moving component and a lifting moving component for correcting and aligning bar stock 2 of different diameters with the feed inlet of the heating furnace 2. The horizontal pushing component is installed on top of the transverse moving component, and the transverse moving component is installed on top of the lifting moving component.

[0043] During operation, bar stock 2 is first loaded onto the horizontal pushing component and pushed towards the feed inlet of the heating furnace 2. During this pushing process, the relative position of bar stock 2 and the feed inlet of the heating furnace 2 is adjusted according to the diameter of bar stock 2 to ensure precise alignment. Specifically, the horizontal movement component corrects the horizontal direction, and the lifting movement component corrects the height position. This method enables precise feeding and pushing of bar stock 2 of various specifications.

[0044] The specific structure of the horizontal pushing component is as follows: The horizontal pushing component includes a horizontal lead screw frame 32, within which a first lead screw is rotatably connected (in the existing method, bearing seats rotatably connected to the first lead screw are installed at both ends of the horizontal lead screw frame 32, and the first lead screw is fixedly installed on the inner ring of the bearing in the bearing seat). A lead screw servo motor 31 is installed on the first lead screw. Simultaneously, a horizontal pushing slide 35 is threadedly connected to the first lead screw. Specifically, a first lead screw threaded seat 352 is fixedly connected to the bottom center position of the horizontal pushing slide 35, and the first lead screw threaded seat 352 is threadedly connected to the first lead screw; first slide blocks 353 are fixedly connected to both sides of the bottom of the horizontal pushing slide 35, and first slide rails slidably connected to the first slide blocks 353 are fixedly connected to both sides of the horizontal lead screw frame 32.

[0045] During operation, driven by the lead screw servo motor 31, the horizontal push slide 35 moves horizontally on the horizontal lead screw frame 32.

[0046] Meanwhile, the horizontal pushing component also includes push-limiting rails 34 fixedly installed on both sides of the horizontal lead screw frame 32, and a push channel is formed between the push-limiting rails 34. The side walls of the push-limiting rails 34 facing each other are sloping surfaces, and a V-shaped push channel is formed between the push-limiting rails 34 (the push channel is an open structure at the top and bottom, that is, the lower ends of the push-limiting rails 34 are spaced apart).

[0047] The V-shaped structure design allows for the feeding and positioning of bars 2 of different thicknesses within the V-shaped push channel 341 during operation. Larger diameter bars 2 are positioned on the upper side of the V-shaped push channel 341, while smaller diameter bars 2 are positioned on the lower layer.

[0048] Meanwhile, a pusher hook plate 351 for pushing the bar stock 2 forward is fixedly connected to the top of the horizontal push slide 35 (the shape of the pusher hook plate 351 is: the pusher hook plate 351 includes a base portion fixedly connected to the top position of the horizontal push slide 35, and the base portion is integrally formed with a vertically arranged hook plate portion). The upper end of the pusher hook plate 351 is located inside the push channel 341 (the pusher hook plate 351 passes through the gap between the bottoms of the push channel 341 and enters the V-shaped push channel 341).

[0049] The two ends of the aforementioned push-limiting track 34 are respectively fixedly connected to mounting brackets 33, which are fixed on the outer side wall of the horizontal screw frame 32.

[0050] During operation, the operator turns on the lead screw servo motor 31. Driven by the lead screw servo motor 31, the slide table 35 is moved horizontally and the pusher hook plate 351 pushes the bar stock 2 into the feed port of the heating furnace 2.

[0051] Example 2

[0052] like Figure 1-6 As shown, in order to achieve the relative position of the horizontal straightening bar 2 and the feed inlet of the heating furnace 2, the above-mentioned transverse moving component includes a transverse screw frame 37 arranged perpendicularly to the horizontal screw frame 32. A second screw 38 is rotatably connected inside the transverse screw frame 37 (same as the existing method, bearing frames for rotatably connecting the screw are fixedly connected to both ends of the transverse screw frame 37, and the inner ring of the bearing on the bearing frame is fixed on the second screw 38). A first handle wheel 381 is fixedly installed at the end of the second screw 38.

[0053] Similarly, the second lead screw 38 is threadedly connected to the transverse slide 36, and the horizontal lead screw frame 32 is fixedly installed on the top of the transverse slide 36. Specifically, a second lead screw thread seat 361, which is threadedly connected to the second lead screw 38, is fixedly connected to the center position of the bottom of the transverse slide 36.

[0054] Meanwhile, the bottom sides of the transverse slide table 36 are respectively fixedly connected to the second slide block 362, and the top sides of the transverse screw frame 37 are fixedly connected to the second slide rail that slides to connect the second slide block 362.

[0055] During operation, the operator manually drives the first handle wheel 381, and under the drive of the first handle wheel 381, the transverse slide 36 carries the horizontal pushing component and moves horizontally.

[0056] Example 3

[0057] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, in order to achieve the relative position between the bar stock 2 and the feed inlet of the heating furnace 2 at the height position, the above-mentioned lifting and moving assembly includes a lifting platform 39, and the transverse screw frame 37 is fixedly connected to the top position of the lifting platform 39.

[0058] Specifically, the lifting and moving assembly also includes a lifting screw 391 for lifting the lifting platform 39 (the top of the lifting screw 391 is rotatably connected to the center of the bottom of the lifting platform 39; specifically, similar to existing methods, the upper end of the lifting screw 391 is a smooth end, and the lifting platform 39 has a groove for rotatably connecting the upper end of the lifting screw 391). The lifting screw 391 is threadedly connected to a worktable 5 (the worktable 5 serves as the platform for the entire device). During the rotation of the lifting screw 391, the screw thread drives the lifting screw 391 to rise or fall.

[0059] Meanwhile, a drive wheel is fixedly connected to the bottom of the lifting screw 391. In order to increase the stability of lifting, several slide rods 392 are fixedly connected to the bottom of the lifting platform 39 and slidably connected to the worktable.

[0060] The above method is used to correct the relative position between the bar stock 2 and the feed inlet of the heating furnace 2 during the pushing process of the bar stock 2.

[0061] Example 4

[0062] like Figure 1-6 As shown, this embodiment, based on the structure of embodiment 2, installs upper limit switches on both mounting brackets in the existing manner. Specifically, an end-point limit sensor 42 is installed on the mounting bracket near the feed inlet of the heating furnace 2, and a start-point limit sensor 41 is installed on the mounting bracket near the lead screw servo motor 31. During operation, when the bar stock 2 exceeds the distance between the start-point limit sensor 41 and the end-point limit sensor 42 due to excessive length, the sensors trigger an alarm, indicating that the bar stock 2 is too long.

[0063] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
