Description

Technical Field

[0001] The utility model relates to the technical field of hardware material strip production, in particular to a three-dimensional stamping device for hardware material strips. Background Art

[0002] At present, in the production process of the hardware strips of the LED bracket, the hardware strips need to be stamped and formed. In the prior art, the structure adopted is that a fixing seat is provided, a bearing block is installed inside the fixing seat, one end of the bearing block is provided with a forming groove, and the other end is provided with a spring. A punch is provided above the fixing seat. Under the action of the punching machine, the punch can be driven to press down and press the strip into the forming groove. Finally, the punch is reset, and the formed strip is ejected through the bearing block under the action of the spring. However, since the thickness of the forming part of the strip is very thin, it is easy to damage the forming part of the strip or cause the forming part of the strip to deform, thereby increasing the defective rate.

[0003] Based on the above problems, we propose a three-dimensional stamping device for hardware strips. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a three-dimensional stamping device for hardware strips, which, after being improved, can effectively solve the problems raised in the above-mentioned background technology.

[0005] The technical solution of the utility model is:

[0006] A three-dimensional stamping device for hardware strips comprises a mounting seat and a base; the top surface of the mounting seat is mounted with a base, a cavity is arranged inside the base, a fixing seat is mounted inside the cavity, a forming groove is arranged on the top surface of the fixing seat, a bearing block and a first spring are also mounted inside the cavity, one end of the bearing block extends to the bottom surface of the forming groove, the other end of the bearing block is fixedly connected to the base, one end of the first spring is fixedly connected to the fixing seat, and the other end is fixedly connected to the base;

[0007] A punch is arranged above the base, one end of the punch is connected to the punch head, a hardware strip is arranged between the punch and the base, and the punch head drives the punch to move in the vertical direction to press the hardware strip into the forming groove.

[0008] Furthermore, the number of the first springs is two, and they are arranged at both ends of the bearing block.

[0009] Furthermore, the number of the forming grooves is two; the number of the supporting blocks is two, which are arranged corresponding to the two forming grooves.

[0010] Furthermore, the punching device is also provided with a stripping plate, and the punch is arranged in the stripping plate and is slidably connected to the stripping plate.

[0011] Furthermore, a floating pin is provided inside the base, and a second spring is provided inside the mounting seat, one end of the second spring is connected to the mounting seat and the base and is fixedly connected to the floating pin, the other end of the second spring is fixedly connected to the mounting seat, and one end of the floating pin away from the second spring is connected to the base and exposed outside the base.

[0012] The beneficial effects of the utility model are:

[0013] Compared with the prior art, the utility model is provided with a fixed seat, a first spring, a floating pin and a second spring. When the punch resets after completing stamping, the first spring can push the fixed seat upward, and then eject the material strip from the forming groove. Since the contact area between the fixed seat and the material strip is large, the material strip is evenly stressed during ejection, so the material strip forming part will not be damaged or deformed during the ejection process. Moreover, under the action of the floating pin and the second spring, the material strip can be completely ejected from the fixed seat and returned to the original horizontal position, and the stamping of the next position of the material strip can be continued. During the ejection process of the material strip, the utility model will not cause deformation or damage to the forming part of the material strip, thereby greatly reducing the defective rate, effectively ensuring the quality of the material strip during the stamping process, and having strong practicality.

[0020] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0021] like Figure 1-5 As shown,

[0022] A three-dimensional stamping device for hardware strips, comprising a mounting seat 1 and a base 2; the top surface of the mounting seat 1 is mounted with the base 2, the interior of the base 2 is provided with a cavity, the interior of the cavity is mounted with a fixing seat 3, the top surface of the fixing seat 3 is provided with a forming groove 4, the interior of the cavity is also mounted with a bearing block 5 and a first spring 6, one end of the bearing block 5 extends to the bottom surface of the forming groove 4, the other end of the bearing block 5 is fixedly connected to the base 2, one end of the first spring 6 is fixedly connected to the fixing seat 3, and the other end is fixedly connected to the base 2; the base 2 A punch 7 is arranged above the punch 7, one end of which is connected to the punch head, and a hardware strip 11 is arranged between the punch 7 and the base 2. The punch head drives the punch 7 to move in the vertical direction to press the hardware strip 11 into the forming groove 4; in this embodiment, the supporting block 5 is fixedly arranged, the purpose of which is to limit the forming groove 4 so that the punch 7 will not be too large or too small during stamping; in addition, the forming groove 4 is arranged to communicate with the top surface of the fixed seat 3, and a sliding hole is also arranged between the forming groove 4 and the top surface of the fixed seat 3, so that the punch 7 can press the hardware strip 11 in.

[0023] As a preferred embodiment, the number of the first springs 6 is two and they are arranged at both ends of the bearing block 5; the purpose of this design is to make the elastic force on the fixing seat 3 more uniform and the fixing seat 3 more stable when rising or falling.

[0024] As a preferred embodiment, the number of the forming grooves 4 is two; the number of the bearing blocks 5 is two, corresponding to the two forming grooves 4; and the number of the punches 7 is also two.

[0025] As a preferred embodiment; the stamping device is also provided with a stripper plate 8, the punch 7 is arranged in the stripper plate 8, and is slidably connected to the stripper plate 8; it can be understood that the stripper plate 8 is also arranged on the stamping head, and is fixedly installed. When the stamping head is descending and reaches the descending position, the stripper plate 8 will no longer continue to descend. At this time, the stamping block on the stamping head will continue to drive the punch 7 to descend, so that the punch 7 slides along the stripper plate 8, and finally presses the hardware strip 11 into the molding groove 4.

[0026] As a preferred embodiment; a floating pin 9 is also provided inside the base 2, and a second spring 10 is provided inside the mounting seat 1, one end of the second spring 10 is connected to the mounting seat 1 and the base 2 and fixedly connected to the floating pin 9, and the other end of the second spring 10 is fixedly connected to the mounting seat 1, and the end of the floating pin 9 away from the second spring 10 is connected to the base 2 and exposed outside the base 2; it can be understood that the first spring 6 and the fixing seat 3 can only push the molding part of the hardware strip 11 out of the molding groove 4, but not completely leave it, so the floating pin 9 is needed to continue to push the hardware strip 11 up, and then push the hardware strip 11 out completely. Under this structure, the secondary ejection structure reduces the ejection strength each time, and can further protect the molding part of the hardware strip 11 from damage.

[0027] The working principle of the utility model is as follows: the hardware material strip 11 is arranged between the punch 7 and the base 2, and the hardware material strip 11 is arranged in a roll, and a reeling mechanism and a reeling mechanism are respectively arranged at both ends; when working, under the action of the external punch head, the punch 7 is moved down, and when the stripping plate 8 is limited, the punch 7 can continue to slide along the stripping plate 8, and the forming part of the hardware material strip 11 is pressed into the forming groove 4, and the fixing seat 3, the first spring 6, the floating pin 9 and the second spring 10 will be squeezed during the stamping process; during the stamping After the punch 7 is reset (the force of the punch 7 is lost), the first spring 6 will first bounce the fixing seat 3 upward, and push the hardware strip 11 out of the forming groove 4 (but not completely). When the first spring 6 reaches the maximum extension distance, the fixing seat 3 can no longer push the hardware strip 11, but the second spring 10 still has elastic force at this time, and can continue to push the hardware strip 11 out, until the second spring 10 reaches the maximum extension distance, the hardware strip 11 is completely pushed out and returns to the original horizontal position;

[0028] It should be pointed out that the main problems in the prior art are: the thickness of the strip forming part is very thin, and directly using the bearing block to push it out can easily damage the strip forming part or cause the strip forming part to deform, thereby increasing the defective rate;

[0029] Therefore, through the improvement of the present application, during the process of ejecting the material strip, deformation or damage to the forming part of the material strip will not be caused, thereby greatly reducing the defective rate and effectively ensuring the quality of the material strip during the stamping process.

[0030] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
