Technical Field
[0001] The utility model relates to the technical field of mechanical parts manufacturing, in particular to a shearing machine used for manufacturing mechanical parts. Background Art
[0002] Mechanical parts refer to parts made by cutting, drilling and grinding raw materials through mechanical processing methods. They are an indispensable part of mechanical equipment. During the production and processing of these mechanical parts, the raw materials of the mechanical parts often need to be sheared for further processing.

[0013] Preferably, a reinforcing plate is welded to one side of the bottom end of the fixed plate, and the other side of the reinforcing plate is welded to one side of the shearing machine body to reinforce the structural strength of the fixed plate itself and improve the bearing and compression resistance of the fixed plate itself.

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Example 1
[0028] The preferred embodiment of the shearing machine for manufacturing mechanical parts provided by the utility model is as follows: Figures 1 to 5 As shown: A shearing machine for manufacturing mechanical parts includes a shearing machine body 1, one side of the top of the shearing machine body 1 is rotatably connected with guide rollers 3 at equal intervals, one side of the shearing machine body 1 is provided with a centering component 2, the upper end of the other side of the shearing machine body 1 is provided with a discharge groove 5, and the two ends of the other side of the shearing machine body 1 below the discharge groove 5 are provided with fixed length components 4.
[0029] The centering component 2 includes a reserved groove 203, which is arranged at the upper end of one side of the inner part of the shearing machine body 1. The inner wall of the reserved groove 203 is rotatably connected with a positive and negative threaded rod 205, one end of the positive and negative threaded rod 205 is fixedly connected with a turning handle 201 extending to the outside of the shearing machine body 1, and both ends of the surface of the positive and negative threaded rod 205 are threadedly connected with a threaded block 206, and one side of the threaded block 206 is fixedly connected with a centering plate 202 extending to the outside of the shearing machine body 1. The positive and negative threaded rods 205 are rotated by rotating the turning handle 201, so that the threaded block 206 slides and drives the centering plate 202 to slide until the distance between them is slightly larger than the width of the plate to be cut. After that, the staff places the plate at the top of the shearing machine body 1 between the centering plates 202 for horizontal centering and transportation, so as to avoid the error caused by the tilt of the cutting surface caused by the tilt of the plate during traditional transportation, thereby ensuring the accuracy of the plate cutting processing.
[0030] In this embodiment, one side of the inner wall of the center plate 202 is beveled, and the cross-section of the center plate 202 is an inverted L-shape. By using the center plate 202 with beveled edges, the two center plates 202 form a trumpet shape, which facilitates the plate to pass through between the center plates 202.
[0031] In this embodiment, one end of the center plate 202 is rotatably connected to a guide wheel 204 at equal intervals. The center plate 202 and the guide wheel 204 are symmetrically distributed about the vertical center axis of the shearing machine body 1. The rotating guide wheel 204 is utilized to reduce the friction between the two sides of the plate and the center plate 202, so that the plate can slide out more smoothly from between the center plates 202.
[0032] In this embodiment, a sliding structure is formed between the thread block 206 and the inside of the reserved groove 203. The cross-sections of the reserved groove 203 and the thread block 206 are inverted convex. By sliding between the inverted convex thread block 206 and the inside of the reserved groove 203, the thread block 206 can drive the center plate 202 to slide more smoothly.
[0033] Example 2
[0034] On the basis of Example 1, the preferred embodiment of the shearing machine for manufacturing mechanical parts provided by the utility model is as follows Figures 1 to 5 As shown: the fixed length component 4 includes a fixed plate 402, which is fixedly connected to the two ends of the other side of the shearing machine body 1, and a fixing groove 407 is opened inside the fixed plate 402. A scale slide 403 extending to the outside of the fixed plate 402 is movably connected inside the fixing groove 407. A thrust block 404 is fixedly connected to one side of the top of the scale slide 403, and a rubber block 405 is fixedly connected to one side of the bottom end of the fixed plate 402 at an equal angle. A locking bolt 406 is threadedly connected to one side of the bottom end of the fixed plate 402. The thrust block 404 is pulled to drive the scale slide 403 to slide, and the scale value at the top of the scale slide 403 is used to judge that the distance between one side of the thrust block 404 and the shearing machine body 1 is equal to the length to be cut, and then the locking bolt 406 is tightened to achieve the limited fixation of the scale slide 403 after sliding. After that, the staff only needs to push the plate until one end of it is against the thrust block 404 to achieve fixed-length cutting, avoiding the cumbersome inconvenience of frequent measurements before each cutting in the traditional way.
[0035] In this embodiment, a reinforcement plate 401 is welded to one side of the bottom end of the fixed plate 402, and the other side of the reinforcement plate 401 is welded to one side of the shearing machine body 1. The welded reinforcement plate 401 is used to reinforce the structural strength of the fixed plate 402 itself, thereby improving the bearing and compressive resistance of the fixed plate 402 itself.
[0036] In this embodiment, a sliding structure is formed between the scale slide 403 and the interior of the fixed groove 407. The cross-section of the scale slide 403 and the fixed groove 407 is in the shape of an I-shape. The sliding of the I-shaped scale slide 403 and the interior of the fixed groove 407 is utilized to improve the sliding stability of the two.
[0037] In this embodiment, the shape of the rubber block 405 in the top view is arc-shaped, and there are three rubber blocks 405 distributed at equal angles. The equal-angle and arc-shaped rubber blocks 405 are used to improve the tightness of the locking bolt 406 after tightening, thereby preventing the locking bolt 406 from accidentally rotating and causing the scale slide 403 to slip.
[0038] The working principle and use process of the utility model are as follows: first, the locking bolt 406 is loosened, and then the thrust block 404 is pulled to drive the scale slide 403 to slide inside the fixing groove 407, and the distance between one side of the thrust block 404 and the shearing machine body 1 is judged by the scale value at the top of the scale slide 403, and the distance is made equal to the length to be cut, and then the locking bolt 406 is tightened to achieve the limited fixation of the scale slide 403 after sliding, and the arc-shaped rubber block 405 is used to improve the tightness of the locking bolt 406 after tightening, so as to avoid the sliding of the scale slide 403 caused by the accidental rotation of the locking bolt 406;
[0039] Then, the handle 201 is rotated to drive the positive and negative threaded rods 205 to rotate, and the threads of the positive and negative threaded rods 205 and the threaded block 206 are matched, so that the threaded block 206 slides and drives the center plate 202 to slide, until the distance between the sides of the center plate 202 is slightly larger than the width of the plate to be cut. Then, the staff puts the plate on the top of the shearing machine body 1 between the center plates 202, and uses the rotating guide wheel 204 and the guide roller 3 to make the plate more smoothly and horizontally transported to it, avoiding the error caused by the tilt of the cutting surface caused by the tilt of the plate during traditional transportation, thereby ensuring the accuracy of the plate cutting process;
[0040] The staff continues to push the plate until one end of the plate is against the thrust block 404, and then the shearing machine body 1 works to cut the plate. Because the distance between one end of the thrust block 404 and one side of the shearing machine body 1 is fixed, the length of the plate is fixed after each cutting, thereby achieving fixed-length cutting, avoiding the tedious and inconvenient need for frequent measurements before each cutting, and reducing the workload of the staff during cutting.
[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
