Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically a pressing device for the production and processing of mechanical parts. Background Technology

[0002] The production process of a machine refers to the entire process of turning raw materials or semi-finished products into finished products. For machine production, this includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly and debugging, painting and packaging, etc. The production process is very extensive. In the production and processing of mechanical parts, the edge pressing process is crucial to product quality.

[0003] In the current technology for edge pressing of mechanical parts, the overall synchronous edge pressing method is generally adopted. This process completes the edge pressing of the entire circumference in a single punching, which has the advantages of high processing efficiency and suitability for mass standardized production.

[0004] This synchronous edge pressing method has significant technical limitations: because the entire perimeter is subjected to force simultaneously, material stress cannot be effectively released, easily leading to stress concentration in localized areas. This, in turn, causes problems such as wrinkling at the workpiece edges and uneven thickness, severely affecting product quality. Especially for difficult-to-deform materials such as high-strength steel and aluminum alloys, the scrap rate of traditional synchronous edge pressing processes can be as high as 15% or more, not only wasting materials but also increasing the cost of subsequent finishing processes.

[0005] Therefore, this utility model provides a pressing device for the production and processing of mechanical parts to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model provides a pressing device for the production and processing of mechanical parts, such as... Figure 1-5 As shown, it includes a base 1, a pressing device 2 installed on the top of the base 1, and a worktable 3 installed on the base 1;

[0034] The base 1 has a fixed chamber 4 inside, and a sleeve 5 is rotatably connected inside the fixed chamber 4. The top of the sleeve 5 is connected to the bottom of the workbench 3.

[0035] The fixed chamber 4 is equipped with a drive mechanism 6, which drives the sleeve 5 to rotate the worktable 3 90° back and forth to realize the switching of the workpiece pressing position.

[0036] Two sliding clamps 7 are symmetrically arranged on the base 1;

[0037] The fixed chamber 4 is also equipped with a linkage mechanism 8, which is mechanically coupled to the drive mechanism 6. It is used to drive the two clamping plates 7 to move towards each other to clamp the workpiece after the worktable 3 is rotated into position. The workpiece is placed on the worktable 3, and the drive mechanism 6 drives the worktable 3 to rotate precisely by 90°. With the help of the linkage mechanism 8, the worktable 3 rotates and drives the clamping plates 7 to move towards each other until the two clamping plates 7 are attached to the side wall of the workpiece, thereby positioning the workpiece. Then, the edge pressing device 2 performs edge pressing processing on both sides of the workpiece. After the edge pressing on both sides is completed, the drive mechanism 6 drives the worktable 3 to rotate in the opposite direction by 90°. The above process is repeated until all four sides are processed.

[0038] like Figure 1 As shown, the pressing device 2 includes a support 21;

[0039] A bracket 21 is connected to the top of the base 1. A first electric push rod is installed on the bracket 21. A pressing die 22 is connected to the end of the first electric push rod. Two sliding rods 23 are slidably connected to the bracket 21. The bottom ends of the two sliding rods 23 are connected to the top of the pressing die 22. The first electric push rod pushes the pressing die 22 down along the sliding rods 23. The sliding rods 23 ensure that the pressing die 22 moves vertically. The pressing die 22 is used to press the edges of the workpiece.

[0040] like Figure 3 and Figure 4 As shown, the drive mechanism 6 includes a gear 61;

[0041] A gear 61 is connected to the outer wall of the sleeve 5. Two racks 62 are meshed on the outer wall of the gear 61. Both racks 62 are slidably connected inside the fixed chamber 4. A second electric push rod is installed on the outer wall of the base 1. The end of the second electric push rod is connected to the end of either rack 62. The second electric push rod pushes the rack 62 connected to it to move, causing the rack 62 to drive the gear 61 to rotate, thereby driving the sleeve 5 to drive the worktable 3 to rotate precisely 90°.

[0042] like Figure 3 and Figure 4As shown, two T-shaped grooves 63 are provided inside the fixed chamber 4. A T-shaped slider 64 is slidably connected inside each T-shaped groove 63. The top of each T-shaped slider 64 is connected to the rack 62. When the rack 62 moves, it drives the T-shaped slider 64 connected to it to slide inside the T-shaped groove 63, thereby ensuring the stability of the rack 62 when it moves.

[0043] like Figure 3 and Figure 4 As shown, the linkage mechanism 8 includes a connecting rod 81;

[0044] Each rack 62 has a connecting rod 81 rotatably connected to its side wall, and each connecting rod 81 has a vertical rod 82 rotatably connected to its top. The base 1 has two symmetrically opened limiting grooves 83. Each vertical rod 82 is slidably connected inside the corresponding limiting groove 83, and the upper end of each vertical rod 82 is connected to the clamping plate 7. When the rack 62 moves, the connecting rod 81 pushes the vertical rod 82 to slide along the limiting groove 83. The two vertical rods 82 drive the clamping plate 7 to move towards each other until the two clamping plates 7 are in contact with the side wall of the workpiece, thereby positioning the workpiece.

[0045] like Figure 3 and Figure 5 As shown, a movable seat 31 is slidably connected inside the worktable 3, and a movable rod 32 is connected to the bottom end of the movable seat 31. The movable rod 32 is slidably connected to the inner wall of the sleeve 5. A third electric push rod is installed inside the base 1, and the end of the third electric push rod is connected to the bottom end of the movable rod 32. After the four sides of the workpiece are processed, the movable rod 32 is driven by the third electric push rod to drive the movable seat 31 to rise and eject the workpiece, thereby facilitating the demolding of the workpiece.

[0046] like Figure 1 As shown, rubber pads are provided on the side walls of both clamping plates 7; the rubber pads provide flexible clamping force.

[0047] Working principle: First, the workpiece is placed on the worktable 3. The second electric actuator pushes the rack 62 connected to it to move, causing the rack 62 to drive the gear 61 to rotate, which in turn drives the sleeve 5 to drive the worktable 3 to rotate precisely 90°. When the rack 62 moves, it drives the T-shaped slider 64 connected to it to slide inside the T-shaped groove 63, thus ensuring the stability of the rack 62 during movement. When the rack 62 moves, it pushes the upright 82 to slide along the limiting groove 83 through the connecting rod 81. The two uprights 82 drive the clamping plates 7 to move towards each other. Until the two clamping plates 7 are attached to the side wall of the workpiece, thus positioning the workpiece, the first electric push rod pushes the pressing die 22 down along the slide rod 23. The slide rod 23 ensures that the pressing die 22 moves vertically. The pressing die 22 performs pressing processing on both sides of the workpiece. After the pressing of both sides is completed, the drive mechanism 6 drives the worktable 3 to rotate 90° in the opposite direction. The above process is repeated until the processing of all four sides is completed. Then, the third electric push rod drives the movable rod 32 to drive the movable seat 31 to rise, ejecting the workpiece and facilitating demolding.

[0048] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
