Description

Technical Field

[0001] The utility model relates to the technical field of plate punching devices, in particular to a plate punching and demoulding mechanism. Background Art

[0002] Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature, causing it to separate or plastically deform, thereby obtaining the required parts. The stamping mold is a special process equipment that processes the material into parts during the stamping process. The stamping mold generally includes a fixed lower mold and a movable upper mold that is movable along the upper and lower sides. The upper punch is fixed on the movable upper mold, and the lower concave mold is fixed on the fixed lower mold. The stamping mold needs to be demolded once each time the pressurization is completed.

[0003] At present, the demoulding of stamping dies is generally completed by a lifting mechanism, that is, a gas rod or a hydraulic rod is embedded in the die. After the stamping process is completed, the gas rod or the hydraulic rod is started to lift the stamped workpiece and separate it from the stamping die. This demoulding method has the following defects:

[0004] Since the metal sheet will deform during the stamping process, the stamping die will not deform, and the sheet may be stuck on the stamping die. Directly using pneumatic rods or hydraulic rods to lift it without eliminating the deformation stress may cause the stamping workpiece to be scratched by the pneumatic rods or hydraulic rods, affecting production efficiency.

[0031] Hereinafter, a sheet material stamping and demolding mechanism according to one embodiment of the present invention will be described with reference to the accompanying drawings.

[0032] Please refer to Figure 1-Figure 3 As shown, a plate stamping and demoulding mechanism includes a base plate 1, a stamping assembly and a demoulding assembly arranged on the base plate 1, the stamping assembly is used to stamp the metal plate, and the demoulding mechanism is used to separate the plate processed by the stamping assembly from the stamping assembly;

[0033] Among them, since the metal sheet is deformed during the stamping process, the stamping die 102 does not deform, and the sheet may be stuck on the stamping die 102, which makes manual demoulding difficult. Therefore, a demoulding mechanism is required to demould the metal sheet.

[0034] A rack 101 is provided on the bottom plate 1. The rack 101 is provided in a U-shaped frame and is fixedly assembled with the bottom plate 1. Both ends of the U-shaped frame are respectively fixed on the bottom plate 1.

[0035] About stamped components, including:

[0036] There are two stamping dies 102, one of which is set on the base plate 1, and the other is installed on the inner side of the frame 101 close to the base plate 1 through a hydraulic cylinder 104;

[0037] Each stamping die 102 is provided with a stamping block 102 - 1 ;

[0038] Specifically, the shape of the stamping block 102-1 is determined according to the process requirements. The two stamping blocks 102-1 schematically depicted in the accompanying drawings are a rectangular stamping block 102-1 and a groove-shaped stamping block 102-1, and the two stamping blocks 102-1 are adapted to each other.

[0039] The positioning post 103 is installed on one of the stamping dies 102, and the other stamping die 102 is provided with a positioning hole 103-1 adapted to the positioning post 103;

[0040] Specifically, the positioning column 103 and the positioning hole 103-1 are used to assist in positioning the two stamping dies 102 toward each other, reduce the deviation of the two stamping dies 102 toward each other, and improve the stamping processing accuracy;

[0041] When in use, the staff places the metal sheet to be stamped into the punching block 102-1 on the punching die 102 on the base plate 1, starts the hydraulic cylinder 104, and drives the punching die 102 at the output end of the hydraulic cylinder 104 to move toward the punching die 102 on the base plate 1. When the two punching blocks 102-1 on the two punching dies 102 are pressed together, the part is stamped (including punching cutting and punching forming);

[0042] Regarding demoulding components, including:

[0043] The vibration motor 3 is fixed to the outer wall of the stamping die 102 through the mounting plate 3-1;

[0044] The mounting plate 3-1 is configured as a flange plate or an electromagnet. When the flange plate is used to mount the vibration motor 3, the vibration motor 3 is mounted using a threaded assembly process. When the electromagnet is used to mount the vibration motor 3, it can only be used when the stamping die 102 is made of ferromagnetic metal and the electromagnet has a housing made of ferromagnetic metal. However, compared to the flange plate connection with threaded assembly, it has the characteristics of easy assembly and disassembly, reducing the workload of the staff.

[0045] Specifically, the number of vibration motors 3 is set to be several, and at least one is set on each stamping die 102;

[0046] When in use, after the stamping process is completed, since the sheet material is stuck on the stamping die 102, it is relatively laborious for the staff to directly remove it. Therefore, the vibration motor 3 is started to drive the stamping die 102 and the stamping block 102-1 to vibrate at a high frequency, thereby releasing the deformation stress of the sheet material after the stamping process, thereby releasing the stuck state between the sheet material and the stamping die 102, and facilitating the staff to remove the stamped workpiece;

[0047] Regarding demoulding components, it also includes:

[0048] The mounting channel 4 is provided inside the stamping die 102 and the stamping block 102-1 and is used for mounting the parts included in the demoulding assembly;

[0049] Specifically, the mounting channel 4 on the inner side of the punch block 102 - 1 is connected to the mounting channel 4 on the inner side of the punch die 102 ;

[0050] The mounting channel 4 located inside the punching block 102 - 1 extends to the outside of the punching block 102 - 1 and points to another punching block 102 - 1 included in another punching die;

[0051] The cylinder 401 is fixed in the mounting channel 4, and a gas rod 402 is provided at the output end of the cylinder 401;

[0052] Shock absorber 402-1 is provided at the free end of cylinder 401;

[0053] The output end of the cylinder 401 points to the punching block 102-1 included in the other punching die 102. During the punching process, the end face of the damping block 402-1 close to the other punching die 102 and the end face of the punching block 102-1 on which the damping block 402-1 is installed are located in the same plane. That is, the damping block 402-1 fills the mounting channel 4, thereby preventing the blind hole on the punching block 102-1 from affecting the punching process accuracy.

[0054] The air pipe 401-1 is provided in the mounting channel 4, one end of which is connected to the cylinder 401 and the other end of which extends to the outside of the stamping die 102;

[0055] Specifically, the end of the air pipe 401 - 1 extending to the outside of the stamping die 102 is fixed to the stamping die 102 via a fixing plate 401 - 1 a ;

[0056] When in use, the air pipe 401-1 is connected to the high-pressure air connector (an industrial high-pressure gas supply connector, derived from the prior art, for providing compressed air). After the stamping process is completed, the air cylinder 401 is started, and the plate on the stamping block 102-1 is lifted by the air rod 402 to complete the demoulding operation between the plate and the stamping die 102 and the stamping block 102-1. The shock-absorbing block 402-1 can prevent the plate from being scratched or broken during the lifting process of the air rod 402, resulting in a poor surface of the plate. In addition, in conjunction with the above-mentioned vibration motor 3, the demoulding efficiency can be further improved to prevent the air rod 402 from damaging the plate during operation.

[0057] Regarding demoulding components, it also includes:

[0058] Control button 2, arranged on the bottom plate 1;

[0059] Specifically, the above-mentioned cylinder 401 and vibration motor 3 are controlled by a PLC controller or a single-chip microcomputer, and the control button 2 is connected to the PLC controller or the single-chip microcomputer to realize the control of the cylinder 401 and the vibration motor 3, making it convenient for the staff to remove the plate located on the stamping die 102 and the stamping block 102-1.

[0060] Compared with the prior art, the present invention has the following features:

[0061] The vibration motor 3 is easy to install and adjust, which can realize vibration demoulding and is easy to use;

[0062] Based on the demoulding by vibration and the demoulding by lifting by the cylinder 401 , the deformation stress on the plate during the stamping process can be eliminated in advance, thereby avoiding damage to the plate during the lifting process of the gas rod 402 .

[0063] The present invention is not limited to the embodiment, and various modifications can be made without departing from the spirit of the present invention.
