Description

Technical Field

[0001] The utility model relates to the technical field of metal parts processing, in particular to a bottom plate hardware punching and cutting device. Background Art

[0002] A long metal base plate with mounting holes at both ends (such as Figure 6 As shown), during production and processing, the base plate is continuously rolled by a metal coil through a roller press to roll the cross section of the base plate into the required shape. The existing production process is to cut the rolled strip raw material and then manually transfer the cut base plate to the punching machine. However, this manufacturing process is relatively cumbersome and requires manual transfer processing. There are also problems. For example, when punching, the base plate needs to be repositioned. During the secondary positioning, it is easy for the distance between the mounting hole and the end edge of the base plate to have a certain deviation. The margin tolerance requirement of the mounting hole is relatively high. The secondary positioning punching form easily leads to a low yield rate and low production efficiency. Therefore, the utility model proposes a base plate hardware stamping and cutting device to improve the production efficiency and yield rate of the base plate. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0028] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically specified.

[0029] Reference Figure 1-6 As shown, a bottom plate 11 hardware stamping and cutting device includes:

[0030] An upper die base 1, the lower end surface of which is connected to an upper stripping plate 4 via a spring, a cutter 2 for cutting the strip material and two punches 3 located on the feed side and the discharge side of the cutter 2 are provided on the lower end surface of the upper die base 1, and the upper stripping plate 4 is provided with holes passing through the upper and lower ends for avoiding the cutter 2 and the punches 3;

[0031] The lower die base 6 has a lower die plate 5 on its upper end surface. The lower die plate 5 has a first punching hole 5011 for clearance fit with the cutter 2 to achieve blanking, and a second punching hole 5012 for clearance fit with the two punch rods 3 to achieve blanking. A guide column is provided between the upper die base 1 and the lower die base 6.

[0032] The upper die base 1 can be driven by a hydraulic mechanism, driving the upper die base 1 to move up and down. When the upper die base 1 moves toward the lower die base 6, the upper stripping plate 4 first contacts the strip raw material and presses it onto the lower template 5; the upper die base 1 continues to move toward the lower die base 6 and compresses the spring, and the cutter 2 contacts the strip raw material and cuts it; the upper die base 1 continues to move toward the lower die base 6, and the punch rod 3 contacts the strip raw material and punches it through, forming the mounting hole 1103 on the bottom plate 11. It should be noted that the feeding positioning of the strip raw material is performed by the roller press, and the hardware stamping and cutting device of the bottom plate 11 is arranged at the discharge end of the roller press.

[0033] Specifically, the upper stripping plate 4 is provided with two avoidance channels 401 running through the feed side and the discharge side, which are used to avoid the vertical part 1101 of the bottom plate 11. When the upper stripping plate 4 is in contact with the lower template 5, the upper stripping plate 4 presses the horizontal part 1102 of the bottom plate 11 against the lower template 5.

[0034] Specifically, a die 501 is embedded in the lower template 5, and a first punching hole 5011 and two second punching holes 5012 are provided on the die 501. The first punching hole 5011 and the second punching hole 5012 are provided on the die 501. Since the first punching hole 5011 and the second punching hole 5012 are used for punching, the required material hardness is relatively high. Embedding a die 501 in the lower template 5 can save the material cost of the parts and facilitate maintenance.

[0035] Specifically, an upper pad 10 is also fitted and fixed to the lower end surface of the upper die base 1, and an upper clamping plate 9 is also fitted and fixed to the lower end surface of the upper pad 10. The cutter 2 and the punch 3 are both fixed to the upper clamping plate 9. The upper end surface of the spring passes through the upper pad 10 and the upper clamping plate 9. The upper clamping plate 9 is used to install and position the position of the cutter 2 and the punch 3. It is easier to disassemble and adjust than directly installing it on the upper die base 1, and an upper pad 10 is provided on the upper end surface of the upper clamping plate 9 to prevent the cutter 2 and the punch 3 from directly abutting against the upper die base 1, thereby improving its durability.

[0036] Specifically, a lower pad 7 is provided between the lower die base 6 and the lower mold plate 5 for connecting the lower mold plate 5 and the lower die base 6. Because the lower die base 6 is large in size and high in cost, a lower pad 7 is provided to improve the durability of the lower die base 6.

[0037] Specifically, a group of limit blocks 8 are also provided on the lower template 5. The limit blocks 8 are used to limit the position of the strip material in the left and right directions. Although the position positioning of the strip material is not easy to shift when it is output from the roller press, two limit blocks are set to improve the accuracy of the distance between the mounting holes 1103 and the left and right sides; the corresponding upper stripping plate 4 is provided with holes for avoiding the limit blocks 8, and the limit blocks 8 are also provided with notches for avoiding the cutting knife 2.

[0038] Specifically, the two limit blocks 8 are installed on the lower template 5 in a plug-in manner, which is convenient for maintenance and disassembly, and the limit block 8 is provided with a limit part that passes through the feed side and the discharge side. The contour of the limit part corresponds to the vertical part 1101 of the bottom plate 11, and the sliding clearance is matched, which can also prevent the vertical part 1101 from excessive deformation when the cutter 2 is pressed down for cutting.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
