Description

Technical Field

[0001] The utility model relates to the technical field of the manufacture of bolt rods, in particular to a bar drawing machine and a guiding device thereof. Background Art

[0002] In the automobile manufacturing industry, bolts for fixing wheel hubs are required. The raw material of such bolts is a bar stock with a diameter close to the bolt rod diameter, and the length of the bar stock is about 6 - 8 meters. When the bar stock enters the factory, there are defects such as ovality and bending. In order to make the defective bar stock round and straight, it needs to go through annealing treatment and bar drawing process in sequence in the subsequent processing to meet the requirements. The bar stock after annealing treatment will become soft, and since the bar stock is supported by spacer blocks in the annealing furnace, there is a certain distance between the spacer blocks to make the bar stock heated evenly, which causes the unsupported parts of the bar stock to bend downward under the action of gravity, making the bar stock form an S shape, and the deformation at both ends of the bar stock is more serious. In the bar drawing process, a bar drawing machine is used to correct the above defects of the bar stock. When the existing bar drawing machine is working, the bar stock needs to be conveyed into the bar drawing die through manual or automatic feeder. However, the method of manually conveying the bar stock requires the operator to hold one end of the bar stock and send it into the bar drawing die, which is not only time-consuming and laborious, but also has low efficiency; when the bar stock is conveyed by the existing automatic feeder, there are problems such as jamming, binding, and even damage to the equipment, which poses a safety hazard. Especially when the long bar stock cannot automatically enter the bar drawing die, it seriously affects the working efficiency of the bar drawing machine. Summary of the Utility Model

[0032] The first adjustment assembly 23 includes a first cylinder 31 mounted on a first mounting portion 214, a first movable plate 32 driven by the first cylinder 31, and a first pressing block 34 mounted on an end of the first movable plate 32 away from the first cylinder 31. The first cylinder 31 is a QSC63-50-TC cylinder. The first movable plate 32 is engaged in the first slide rail 211. Preferably, the first movable plate 32 is roughly L-shaped. The corner of the first movable plate 32 is set to a first inclined surface 321 to prevent the entry of the bar 3 from being blocked. A first connecting seat 33 is installed on the side of the first movable plate 32 away from the frame 1, and the output shaft of the first cylinder 31 is connected to the first connecting seat 33. The first pressing block 34 is connected to the first movable plate 32 through a first pressing plate 35. Preferably, a bolt passes through the first pressing plate 35 and the first pressing block 34 and is connected to the first movable plate 32 to clamp the first pressing block 34 between the first pressing plate 35 and the first movable plate 32.

[0033] The second adjusting component 24 includes a second cylinder 41 mounted on the second mounting portion 214, a second moving plate 42 driven by the second cylinder 41, and a second pressing block 44 mounted on one end of the second moving plate 42 away from the second cylinder 41. The second cylinder 41 is a QSC63-50-TC cylinder. The second moving plate 42 is engaged in the second sliding rail 211. Preferably, the second moving plate 42 is generally L-shaped. The corner of the second moving plate 42 is provided with a second inclined surface 421 to prevent the entry of the bar stock 3. A second connecting seat 43 is mounted on the side of the second moving plate 42 facing away from the frame 1, and the output shaft of the second cylinder 41 is connected to the second connecting seat 43. The second pressing block 44 is connected to the second moving plate 42 through a second pressing plate 45. Preferably, bolts pass through the second pressing plate 45 and the second pressing block 44 and are connected to the second moving plate 42 to clamp the second pressing block 44 between the second pressing plate 45 and the second moving plate 42. The guiding channel is formed between the first pressing block 34 and the second pressing block 44. The distance between the first pressing block 34 and the second pressing block 44 is larger than the diameter of the bar stock 3. Preferably, according to the thickness of the bar stock 3, the distance between the first pressing block 34 and the second pressing block 44 is adjusted to be about 3 mm larger than the diameter of the bar stock 3. More preferably, the lower ends of the first pressing block 34 and the second pressing block 44 are respectively flush with the lower end of the feeding port.

[0034] During use, when the bar stock 3 is conveyed to the position of the guiding component 22, if the degree of bending of the bar stock 3 is large, the head of the bar stock 3 will touch the first guiding member 221 or the second guiding member 222. When the head of the bent bar stock 3 touches the first guiding member 221 or the second guiding member 222, it will be naturally straightened, so that the bar stock 3 travels along a predetermined path. If the degree of bending of the bar stock 3 is small, it will continue to move forward without touching the guiding component 22; when the head of the bar stock 3 reaches the position of the adjusting component, the proximity switch sends a signal, and the control system instructs the two cylinders to act. The first pressing block 34 and the second pressing block 44 form a guiding channel, so that the head of the bar stock 3 continues to move forward along the guiding channel until it reaches the bar drawing die. When the bar stock 3 reaches the bar drawing die, another proximity switch sends a signal to the control system, and the adjusting component resets and waits to repeat the next cycle of actions.

[0035] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
