Description

Technical Field

[0001] This utility model belongs to the field of workpiece processing, and specifically relates to a cutting and punching device for workpieces. Background Technology

[0002] Workpiece machining is a series of operations performed on raw materials or semi-finished products to change their physical shape, dimensional accuracy, surface quality, and other properties, thereby producing parts or products that meet specific requirements. These operations typically include various processes such as turning, milling, drilling, grinding, casting, forging, welding, and heat treatment.

[0003] To ensure the accuracy of workpiece machining, it is usually necessary to fix the workpiece, especially for workpieces with thin sidewalls. Choosing a suitable fixing method is particularly important because such workpieces are prone to deformation under force, and improper fixing methods can also cause uneven stress during machining, leading to deformation. Therefore, when processing thin-walled workpieces, special attention must be paid to using appropriate clamping methods and techniques to reduce the risk of deformation caused by improper fixing methods. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is: to propose a cutting and punching device for workpieces, which ensures that the workpiece is firmly fixed by the joint action of the first support block, the second support block, the first fixing block and the second fixing block on the operating table. When cutting the workpiece, even if the inner wall of the workpiece is thin, the risk of deformation due to improper fixing method can be effectively avoided.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a cutting and punching device for workpieces, comprising:

[0006] An operating table is provided with a first support block and a second support block. The workpiece is placed on the first support block and abuts against the second support block.

[0007] The first fixing block is disposed opposite to the first support block and moves against the side of the workpiece away from the first support block;

[0008] The second fixing block is movably inserted into the second support block and moves against the side of the workpiece away from the second support block;

[0009] A push block is movably disposed below the operating table and movably abuts against the second fixed block. The second fixed block can move toward the second support block by being pushed by the push block.

[0010] The workpiece can be fixed on the operating table because its inner wall on one side abuts against the first support block, its outer wall abuts against the first fixing block, its outer wall on the other side abuts against the second support block, and its inner wall abuts against the second fixing block;

[0011] A punching part, which is movably disposed above the operating table, is used for punching holes in the workpiece;

[0012] A cutting component, which is movably disposed below the operating table, is used to cut the workpiece that has been fixed in place.

[0013] In the above-mentioned cutting and punching device for workpieces, the second fixing block is provided with a plug-in part, and the second support block is provided with a plug-in groove. The plug-in part is movably inserted into the plug-in groove for connecting the second fixing block and the second support block.

[0014] In the above-mentioned cutting and punching device for workpieces, a first elastic element is also provided in the insertion groove. One end of the first elastic element abuts against the inner wall of the insertion groove, and the other end abuts against the insertion part. The first elastic element can be compressed and undergo elastic deformation as the second fixing block approaches and abuts against the workpiece.

[0015] In the above-mentioned cutting and punching device for workpieces, a first driving member is also provided below the operating table, and the pushing block is connected to the output end of the first driving member. The first driving member is used to drive the pushing block to move.

[0016] In the above-mentioned cutting and punching device for workpieces, a second driving member is also provided below the operating table. The cutting member is connected to the output end of the second driving member, and the second driving member is used to drive the cutting member to move.

[0017] In the above-mentioned cutting and punching device for workpieces, a push rod is movably arranged on the operating table, which is located above the first fixed block. The push rod is provided with an inclined part, and the first fixed block is provided with an inclined surface. The first fixed block can be pushed closer to the workpiece because the inclined part moves along the inclined surface.

[0018] In the above-mentioned cutting and punching device for workpieces, a second elastic element is also provided inside the first fixing block. One end of the second elastic element abuts against the first support block, and the other end abuts against the inner wall of the first fixing block. The second elastic element can be compressed and undergo elastic deformation as the first fixing block approaches and abuts against the workpiece.

[0019] In the above-mentioned cutting and punching device for workpieces, a third driving member is also provided on the operating table, and its output end is connected to a movable seat. The pushing rod and the punching part are both arranged on the movable seat. The third driving member drives the pushing rod and the punching part to move in the vertical direction through the movable seat.

[0020] In the above-mentioned cutting and punching device for workpieces, a pre-pressing block is also provided on the movable seat, which has a through hole. The end of the punching part away from the movable seat is inserted into the through hole. The pre-pressing block movably abuts against one side of the workpiece in the vertical direction to fix the workpiece in the vertical direction.

[0021] In the above-mentioned cutting and punching device for workpieces, a third elastic element is also provided on the moving seat. One end of the third elastic element abuts against the moving seat, and the other end abuts against the pre-compression block. The elastic element can be compressed and undergo elastic deformation due to the pre-compression block pressing against the workpiece.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) When fixing the workpiece, the inner wall of one side of the workpiece abuts against the first support block and the outer wall abuts against the first fixing block. The outer wall of the other side abuts against the second support block and the inner wall abuts against the second fixing block. The first support block, the second support block, the first fixing block and the second fixing block work together to ensure that the workpiece is firmly fixed. When cutting the workpiece, even if the inner wall of the workpiece is thin, the risk of deformation due to improper fixing method can be effectively avoided.

[0024] (2) The pre-pressure block provides vertical fixation for the workpiece during the punching process, ensuring the accuracy of the punching process;

[0025] (3) The first elastic element, the second elastic element and the third elastic element provide the necessary clamping force while allowing a certain degree of flexible adjustment, thereby avoiding excessive force acting directly on the workpiece and reducing the risk of deformation caused by over-clamping; in addition, after the workpiece is processed, the first elastic element and the second elastic element push the first fixed block and the second fixed block away from the workpiece and return to the initial position; this not only ensures that the workpiece is in a free state after processing, but also provides convenience for subsequent operations (such as removing the workpiece, loading a new workpiece or repeating the processing process).

Detailed Implementation

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0036] like Figure 1 As shown, the cutting and punching device for workpieces in this solution is mainly used for cutting and punching workpieces. When processing the workpiece, a suitable fixing method is selected to ensure that the workpiece will not be deformed due to its thin sidewalls.

[0037] like Figures 1 to 7As shown, this solution provides a cutting and punching device for workpieces, comprising: an operating table 1, on which a first support block 2 and a second support block 3 are disposed; the workpiece is placed on the first support block 2 and abuts against the second support block 3; a first fixing block 4, which is disposed opposite to the first support block 2 and movably abuts against the side of the workpiece away from the first support block 2; a second fixing block 5, which is movably inserted into the second support block 3 and movably abuts against the side of the workpiece away from the second support block 3; a pushing block 6, which is movably disposed below the operating table 1 and movably abuts against the second fixing block 5; the second fixing block 5 can move towards the second support block 3 by being pushed by the pushing block 6; the workpiece can be fixed on the operating table 1 because its inner wall abuts against the first support block 2 on one side, its outer wall abuts against the first fixing block 4, its outer wall abuts against the second support block 3 on the other side, and its inner wall abuts against the second fixing block 5; a punching component 7, which is movably disposed above the operating table 1 for punching holes in the workpiece; and a cutting component 8, which is movably disposed below the operating table 1 for cutting the fixed workpiece.

[0038] The workpiece is accurately positioned on the operating table 1 through pre-drilled positioning holes. At this point, the workpiece is placed on the first support block 2 and abuts against the second support block 3. Next, the first fixing block 4 moves towards one outer wall of the workpiece to prepare for fixing it. Simultaneously, the punching component 7 moves towards the workpiece placed on the operating table 1 to prepare for punching. Then, the first fixing block 4 makes close contact with the workpiece, ensuring that one side of the workpiece is securely fixed. At the same time, the punching component 7 completes the punching of the workpiece. Subsequently, the pushing block 6 pushes the second fixing block 5 towards the other inner wall of the workpiece and makes close contact. At this time, the inner wall of one side of the workpiece abuts against the first support block 2, and the outer wall abuts against the first fixing block 4. The outer wall of the other side abuts against the second support block 3, and the inner wall abuts against the second fixing block 5. The workpiece is punched and fixed on the operating table 1. Then, the cutting part 8 cuts the fixed workpiece, and the cutting and punching of the workpiece are completed. In the whole process, the first support block 2, the second support block 3, the first fixing block 4 and the second fixing block 5 work together to ensure that the workpiece is firmly fixed. When the workpiece is cut, even if the inner wall of the workpiece is thin, the risk of deformation due to improper fixing can be effectively avoided.

[0039] In order to allow the second fixing block 5 to be movably inserted into the second support block 3, the second fixing block 5 is provided with a plug-in part 9, and the second support block 3 is provided with a corresponding plug-in groove 10, and the plug-in part 9 is movably inserted into the plug-in groove 10.

[0040] Furthermore, a first elastic element 11 is also provided in the insertion groove 10. One end of the first elastic element 11 abuts against the inner wall of the insertion groove 10, and the other end abuts against the insertion part 9. When the second fixing block 5 moves closer to the workpiece side and contacts the inner wall of the workpiece, the first elastic element 11 undergoes elastic deformation due to pressure.

[0041] When the second fixing block 5 is in the initial position, the first elastic element 11 is in its natural state. When the pushing block 6 pushes the second fixing block 5 to move, the insertion part 9 moves along the insertion groove 10, and the second fixing block 5 gradually approaches the inner wall on one side of the workpiece. At the same time, the first elastic element 11 is compressed by the pushing force of the insertion part 9 and produces elastic deformation. As the second fixing block 5 advances, the second fixing block 5 comes into close contact with the inner wall on one side of the workpiece, ensuring that the workpiece is firmly fixed. When the workpiece is processed, the pushing block 6 moves away from the second fixing block 5, and the first elastic element 11 is no longer pushed. At this time, the first elastic element 11 returns to its original shape and drives the second fixing block 5 away from the workpiece and back to the initial position through the insertion part 9. The first elastic element 11 provides the necessary clamping force while allowing a certain degree of flexible adjustment, thereby avoiding excessive force acting directly on the workpiece. The first elastic element 11 is preferably a spring.

[0042] In order to drive the push block 6 to move, a first drive component 12 is also provided below the operating table 1. The push block 6 is connected to the output end of the first drive component 12. The first drive component 12 can be a motor, a hydraulic cylinder or a pneumatic cylinder.

[0043] In order to move the cutting piece 8, a second driving component 13 is also provided below the operating table 1. The cutting piece 8 is connected to the output end of the second driving component 13. The second driving component 13 can be a motor, a hydraulic cylinder or a pneumatic cylinder.

[0044] In order to move the first fixed block 4, a push rod 14 is also movably arranged above the operating table 1. It is located above the first fixed block 4. The push rod 14 is provided with an inclined part 15, and the first fixed block 4 is provided with an inclined surface 16. The first fixed block 4 can be pushed closer to the workpiece because the inclined part 15 moves along the inclined surface 16.

[0045] Furthermore, a second elastic element 17 is also provided inside the first fixing block 4. One end of the second elastic element 17 abuts against the first support block 2, and the other end abuts against the inner wall of the first fixing block 4. The second elastic element 17 can be compressed and undergo elastic deformation as the first fixing block 4 approaches and abuts against the workpiece.

[0046] When not being processed, the first fixing block 4 is in its initial position, and the second elastic element 17 is in its natural state. When the push rod 14 moves vertically toward the first fixing block 4, the inclined portion 15 on the push rod 14 first contacts the inclined surface 16 on the first fixing block 4. As the push rod 14 continues to move downward, the inclined portion 15 slides along the inclined surface 16, pushing the first fixing block 4 toward the workpiece. At the same time, the second elastic element 17 is subjected to pressure and undergoes elastic deformation. The first fixing block 4 gradually approaches the workpiece and eventually makes close contact with the workpiece, ensuring that the workpiece is firmly fixed. When processing is completed, the push rod 14 moves away from the first fixing block 4, and the second elastic element 17 is no longer pushed. At this time, the second elastic element 17 returns to its original shape, driving the first fixing block 4 away from the workpiece and back to its initial position. The second elastic element 17 provides the necessary clamping force while allowing a certain degree of flexible adjustment, thereby avoiding excessive force acting directly on the workpiece. The second elastic element 17 is preferably a spring.

[0047] Furthermore, a third driving component 18 is also provided on the operating table 1, and its output end is connected to a movable seat 19. The push rod 14 and the punched part 7 are both set on the movable seat 19. The third driving component 18 drives the push rod 14 and the punched part 7 to move synchronously in the vertical direction through the movable seat 19. The third driving component 18 is preferably an electric cylinder, also known as an electric cylinder or electric push rod. It is an actuator that converts electrical energy into linear motion. It is usually composed of components such as a motor, reducer, lead screw and guide rail. Precise linear displacement control is achieved through the coordinated work of these components.

[0048] Furthermore, a pre-pressing block 20 is also provided on the movable seat 19. The pre-pressing block 20 is provided with a through hole. The end of the punched part 7 away from the movable seat 19 is inserted into the through hole. The pre-pressing block 20 moves against one side of the workpiece in the vertical direction to fix the workpiece in the vertical direction.

[0049] Furthermore, a third elastic element 22 is also provided on the movable seat 19. One end of the third elastic element 22 abuts against the movable seat 19, and the other end abuts against the pre-compression block 20. The elastic element can be compressed and undergo elastic deformation due to the abutment between the pre-compression block 20 and the workpiece. The setting of the third elastic element 22 provides the necessary clamping force while allowing a certain degree of flexible adjustment, thereby avoiding excessive force acting directly on the workpiece. The third elastic element 22 is preferably a spring.

[0050] The processing steps of the workpiece by the cutting-off punching device in this solution are as follows:

[0051] (1) Place the workpiece on the first support block 2 and abut against the second support;

[0052] (2) The third driving component 18 is started, which drives the moving seat 19 and its push rod 14, punching component 7 and pre-pressing block 20 to move down synchronously in the vertical direction.

[0053] (3) Initial contact: The inclined part 15 on the push rod 14 contacts the inclined surface 16 on the first fixed block 4;

[0054] (4) As the moving seat 19 continues to move down, the pre-pressing block 20 begins to contact the workpiece and initially fixes the workpiece in the vertical direction. At this time, the third elastic element 22 is subjected to pressure and undergoes elastic deformation. At the same time, the punching part 7 passes through the perforation on the pre-pressing block 20 and moves closer to the workpiece. The push rod 14 continues to move down, and the inclined part 15 slides along the inclined surface 16, pushing the first fixing block 4 closer to the side wall of the workpiece.

[0055] (5) The punching part 7 contacts the workpiece and completes the punching operation. At the same time, the first fixing block 4 is in close contact with the workpiece to fix the workpiece.

[0056] (6) The first driving component 12 drives the pushing block 6 to push the second fixing block 5 closer to the side wall of the workpiece until the second fixing block 5 abuts against the side wall of the workpiece; at this time, the workpiece is fixed in the horizontal direction as follows: the inner wall of one side of the workpiece abuts against the first support block 2, the outer wall abuts against the first fixing block 4, the outer wall of the other side abuts against the second support block 3, and the inner wall abuts against the second fixing block 5; the workpiece is fixed in the vertical direction by the pre-pressing block 20, and the punching operation has been completed;

[0057] (7) Cutting operation: The second driving component 13 drives the cutting component 8 to approach the workpiece and cut the workpiece.

[0058] (8) During the reset process, after the cutting operation is completed, the third drive member 18 reverses its action, causing the moving seat 19 to rise, the punching member 7 to move away from the workpiece and return to the initial position, the third elastic member 22 to restore its original shape, the pre-pressing block 20 to move away from the workpiece and return to the initial position, and at the same time, the push rod 14 moves away from the first fixed block 4, and the second elastic member 17 drives the first fixed block 4 to reset.

[0059] (9) The first driving member 12 drives the pushing block 6 away from the second fixed block 5, and the first elastic member 11 drives the second fixed block 5 to reset.
