Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to a precision mechanical stamping device. Background Technique

[0002] A stamping device is a forming processing method that uses a press and a die to apply an external force to plates, strips, tubes, profiles, etc., so that they undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) with the required shape and size. The stamping device mainly relies on the action of the press and the die, and makes the material undergo plastic deformation by applying an external force. This processing method belongs to the category of plastic processing (or pressure processing), and is called forging together with forging. Stamping processing is widely used in many fields such as automobiles, electrical appliances, instruments, household appliances, office machinery, etc. Among them, the body, chassis, fuel tank, etc. of automobiles are typical applications of stamping processing. In precision machinery manufacturing, the shape and dimensional accuracy requirements of parts are extremely high. Through precise die design and control, the stamping device can quickly and accurately stamp the raw material into the required shape.

[0003] In the processing of existing precision machinery, various required shapes can be formed through stamping. When discharging, generally, the elastic ejector pin of the stamping device itself is used to eject the workpiece. However, during the stamping process, the workpiece is prone to uneven residual stress distribution, which will cause some parts of the workpiece to fit too tightly with the die, increasing the difficulty of ejection.

[0004] Therefore, a precision mechanical stamping device is proposed. Content of the Utility Model

[0005] In view of the above problems, the utility model provides a precision mechanical stamping device to solve the problems raised in the above background technique.

[0006] The technical solution of the utility model is as follows:

[0007] A precision mechanical stamping device includes a workbench, a gantry, a stamping head, and a stamping plate. The gantry is fixed on the top surface of the workbench, the stamping head is installed on the top surface of the gantry, the stamping plate is fixedly connected to the bottom surface of the telescopic end of the stamping head. On the top surface of the workbench, there is a die block. A die groove is opened on the top surface of the die block. A support plate is arranged on the inner wall of the die groove. An installation opening is opened on the outer surface of the bottom end of the die block. A top block is hinged on the inner wall of the installation opening. The top block is inclined, and the high end is located in the die groove. The bottom end of the top block is located outside the die block and is fixedly connected with a sealing block. A spring wire is fixedly connected between the end of the sealing block away from the top block and the top surface of the workbench.

[0008] The working principle of the above technical solution is as follows:

[0009] Place the material to be stamped on the pallet in the mold groove on the top surface of the mold block. Supported by the gantry, the telescopic end of the stamping head drives the stamping plate to move downward. The stamping plate contacts the material and continuously presses down, causing the pallet to move downward in the mold groove. As the pallet moves downward, it contacts the high end of the inclined top block, and the top block is pressed down until it fits against the bottom of the mold groove. While the top block is being pressed down, the sealing block at its bottom end inserts into the inner wall of the mounting opening to ensure the sealing of the mold groove during the stamping process and prevent material overflow. Subsequently, the stamping head drives the stamping plate to move upward to complete the stamping action.

[0010] In a further technical solution, an arc block is fixedly connected to the side surface of the sealing block away from the spring wire, and the side of the arc block away from the sealing block is an arc-shaped convex surface.

[0011] Through the above technical solution, the arc-shaped convex surface can reduce the contact area between the workpiece and the sealing block. During the process of ejecting the material, the smaller contact area can reduce the frictional force. When the stamped workpiece contacts the sealing block, the arc-shaped convex surface can reduce the frictional resistance between the two, making the ejection action smoother and improving the material discharge efficiency.

[0012] In a further technical solution, a second magnetic attraction block is fixedly connected to the outer surface of the spring wire, and a first magnetic attraction block is fixedly connected to the top surface of the workbench. The first magnetic attraction block and the second magnetic attraction block are used in cooperation.

[0013] Through the above technical solution, during the process of the spring wire dragging the sealing block and the top block to reset, when the first magnetic attraction block and the second magnetic attraction block approach each other, the magnetic attraction force generated between the first magnetic attraction block and the second magnetic attraction block can accelerate the reset speed of the top block, thereby improving the work efficiency.

[0014] In a further technical solution, the spring wire is composed of a first strong spring and a second strong spring. One end of the first strong spring is fixed on the surface of the sealing block. The bottom end of the second strong spring is fixedly connected to the top surface of the first magnetic attraction block. The second magnetic attraction block is fixed at the top end of the second strong spring. The opposite surfaces of the first strong spring and the second strong spring are fixedly connected. The elastic strength of the first strong spring is greater than that of the second strong spring.

[0015] Through the above technical solution, first of all, the first strong spring has a large elastic strength and can provide strong support and stability during the stamping process. When the top block is pressed down, it can effectively resist the pressure, ensure the stable position of the sealing block, maintain the good sealing of the mold groove, and prevent material leakage. Secondly, the second strong spring has a relatively small elastic strength. When the top block resets, it can provide a relatively gentle and precise elastic force control, which helps to avoid impact and damage to the device caused by excessive force during the reset of the top block, and at the same time can more accurately control the reset position of the top block.

[0016] In a further technical solution, a shock pad is fixedly connected to a side surface of the sealing block close to the spring wire, and the shock pad is larger than the length and width of the sealing block.

[0017] Through the above technical solution, it is convenient to provide a shock-absorbing effect during the movement when the sealing block is inserted into the inner wall of the installation opening, and at the same time, it is convenient to further seal the opening of the installation opening.

[0018] In a further technical solution, hinge blocks are fixedly connected to both sides of the connection between the sealing block and the top block, and the sealing block and the top block are hinged to the inner wall of the installation opening through the hinge blocks.

[0019] Through the above technical solution, it is convenient to stably rotate the sealing block and the top block.

[0020] In a further technical solution, four installation openings are provided, and they are arranged in pairs opposite to each other.

[0021] Through the above technical solution, the stability of using the top block to jack up the pallet can be improved, and the stability of blanking can be improved.

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

[0023] 1. For this precision mechanical stamping device, the inclined top block can be pressed down to fit the bottom of the mold groove through the downward movement of the pallet. At the same time, the sealing block can be inserted into the inner wall of the installation opening to keep the mold groove sealed, avoiding material overflow. At the same time, the setting of the spring wire can facilitate dragging the sealing block and the top block to return to their original state after the pressurization is completed, so as to jack up the pallet upward and facilitate discharging.

[0024] 2. Through the restraint and reset of the sealing block and the top block by the spring wire, the second magnetic attraction block can gradually approach the first magnetic attraction block, so that the first magnetic attraction block and the second magnetic attraction block generate suction force, making the top block quickly reset to an inclined state to eject the material from the mold groove.

[0035] Embodiment:

[0036] Please refer to Figures 1-5, A precision mechanical stamping device, including a workbench 1, a gantry 2, a stamping head 3, and a stamping plate 4. The gantry 2 is fixed on the top surface of the workbench 1, the stamping head 3 is installed on the top surface of the gantry 2, and the stamping plate 4 is fixedly connected to the bottom surface of the telescopic end of the stamping head 3. There is a mold block 5 on the top surface of the workbench 1. A mold groove 51 is opened on the top surface of the mold block 5. A support plate 6 is arranged on the inner wall of the mold groove 51. An installation opening 7 is opened on the outer surface of the bottom end of the mold block 5. A top block 9 is hinged on the inner wall of the installation opening 7. The top block 9 is inclined, and the high end is located in the mold groove 51. The bottom end of the top block 9 is located outside the mold block 5 and is fixedly connected with a sealing block 8. A spring wire 10 is fixedly connected between the end of the sealing block 8 away from the top block 9 and the top surface of the workbench 1.

[0037] The working principle of the above technical solution is as follows:

[0038] Place the material to be stamped on the support plate 6 in the mold groove 51 on the top surface of the mold block 5. Supported by the gantry 2, the telescopic end of the stamping head 3 drives the stamping plate 4 to move downward. The stamping plate 4 contacts the material and continues to press down, causing the support plate 6 to move downward in the mold groove 51. As the support plate 6 moves downward, it contacts the high end of the inclined top block 9, and the top block 9 is pressed down until the top block 9 fits against the bottom of the mold groove 51. While the top block 9 is being pressed down, the sealing block 8 at its bottom end is inserted into the inner wall of the installation opening 7 to ensure the sealing of the mold groove 51 during the stamping process and prevent the material from overflowing. Subsequently, the stamping head 3 drives the stamping plate 4 to move upward to complete the stamping action.

[0039] Please refer to Figure 3 and Figure 4 , An arc block 14 is fixedly connected to the side surface of the sealing block 8 away from the spring wire 10, and the side of the arc block 14 away from the sealing block 8 is an arc-shaped convex surface.

[0040] The arc-shaped convex surface can reduce the contact area between the workpiece and the sealing block 8. During the process of ejecting the material, the smaller contact area can reduce the frictional force. When the stamped workpiece contacts the sealing block 8, the arc-shaped convex surface can reduce the frictional resistance between the two, making the ejection action smoother and improving the material ejection efficiency.

[0041] Please refer to Figure 3 and Figure 5 , A second magnetic attraction block 12 is fixedly connected to the outer surface of the spring wire 10, and a first magnetic attraction block 11 is fixedly connected to the top surface of the workbench 1. The first magnetic attraction block 11 and the second magnetic attraction block 12 are used in cooperation.

[0042] During the process of the spring wire 10 dragging the sealing block 8 and the top block 9 to reset, when the first magnetic attraction block 11 and the second magnetic attraction block 12 approach each other, the magnetic attraction force generated between the first magnetic attraction block 11 and the second magnetic attraction block 12 can accelerate the reset speed of the top block 9, thereby improving the working efficiency.

[0043] Please refer to Figure 3 and Figure 5 As shown, the spring wire 10 is composed of a first powerful spring 101 and a second powerful spring 102. One end of the first powerful spring 101 is fixed on the surface of the sealing block 8, the bottom end of the second powerful spring 102 is fixedly connected to the top surface of the first magnetic attraction block 11, the second magnetic attraction block 12 is fixed at the top end of the second powerful spring 102, the opposite surfaces of the first powerful spring 101 and the second powerful spring 102 are fixedly connected, and the elastic strength of the first powerful spring 101 is greater than that of the second powerful spring 102.

[0044] First of all, the first powerful spring 101 has a large elastic strength and can provide strong support and stability during the stamping process. When the top block 9 is pressed down, it can effectively resist the pressure, ensure the stable position of the sealing block 8, maintain the good sealing of the die groove 51, and prevent material leakage. Secondly, the elastic strength of the second powerful spring 102 is relatively small. When the top block 9 returns to its original position, it can provide a relatively gentle and precise elastic force control, which helps to avoid impact and damage to the device caused by excessive force when the top block 9 returns to its original position, and can also more accurately control the return position of the top block 9.

[0045] Please refer to Figure 2 and Figure 4 As shown, a shock pad 13 is fixedly connected to one side of the sealing block 8 close to the spring wire 10, and the shock pad 13 is larger than the length and width of the sealing block 8.

[0046] It is convenient to provide a shock-absorbing effect during the movement when the sealing block 8 is inserted into the inner wall of the installation opening 7, and at the same time, it is convenient to further seal the opening of the installation opening 7.

[0047] Please refer to Figure 3 and Figure 4 As shown, hinge blocks 91 are fixedly connected to both sides of the connection between the sealing block 8 and the top block 9, and the sealing block 8 and the top block 9 are hinged to the inner wall of the installation opening 7 through the hinge blocks 91.

[0048] It is convenient to stably rotate the sealing block 8 and the top block 9.

[0049] Please refer to Figure 1 and Figure 3 As shown, there are four installation openings 7 in total, and they are arranged in pairs opposite to each other.

[0050] It can improve the stability of the top block 9 when lifting the supporting plate 6 and improve the stability of material stripping.

[0051] During operation, place the material to be stamped on the pallet 6 in the die groove 51. Then, the operator drives the stamping head 3 to drive the stamping plate 4 to move downward to stamp the material in the die groove 51. During the stamping process, the pallet 6 moves downward with the material, pressing down the inclined ejector block 9 so that the ejector block 9 fits against the bottom of the die groove 51. At the same time, the sealing block 8 is inserted into the inner wall of the mounting opening 7 to keep the die groove 51 sealed and prevent the material from overflowing. In this process, the spring wire 10 is stretched. When the stamping action is completed, the stamping head 3 drives the stamping plate 4 to reset upward, and the spring wire 10 drags the sealing block 8 and the ejector block 9 to return to their original states. During the reset process, the second magnetic block 12 gradually approaches the first magnetic block 11, and the two generate suction force, causing the ejector block 9 to quickly reset to an inclined state. Subsequently, the ejector block 9 pushes the pallet 6 upward, thereby ejecting the stamped material from the die groove 51 to complete the material removal.

[0052] The above-described embodiments only represent the specific implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
