Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a novel stamping die insert structure. Background Art

[0002] At present, most of the metal backplane structures of televisions are C-shaped or F-shaped structures. The backplane is produced and processed by stamping dies. The C-shaped or F-shaped backplane structures require side pushing for forming. The side pushing structure is an important part of the backplane die. The horizontal movement of the side pushing structure is achieved by converting the vertical movement of the punching press into horizontal movement through an insert on the die. As shown in the attached drawings of the specification, Figure 1 as shown, where 1 in the figure is the insert; 2 is the side pushing slider; 3 is the inner support mechanism. Its working principle is as follows: when the upper and lower dies are closed, the insert contacts and pushes the slider to move horizontally. At the same time, the upper die contacts and moves the lower die, and the inner support mechanism also generates a horizontal displacement under the contact and cooperation of the wedge block, thus completing the stamping operation of the television backplane.

[0003] Since the punching frequency of the backplane stamping die is hundreds of thousands or millions of punches, each time a punch is made, the insert needs to work once to push the side pushing structure to move. The traditional insert is installed on the upper die, and the local work of the insert is stressed. The uneven stress of the insert may cause fracture during hundreds of thousands or millions of punches, which will cause serious damage to the die. If the insert breaks from the upper die and falls onto the lower die, it will not only damage the die but also hurt the employees due to the broken pieces of the die iron flying, posing a major safety hazard. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art that when the insert breaks from the upper die and falls onto the lower die, it not only damages the die but also may hurt the employees due to the broken pieces of the die iron flying, etc., and to propose a novel stamping die insert structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] Design a novel stamping die insert structure, including:

[0007] An upper die base installed with an upper template;

[0008] And a lower die base installed with a lower template;

[0009] Wherein, a driving block is fixedly installed below the upper die base, a side pushing slider is slidably connected above the lower die base, and an insert assembly is further arranged on the lower die base and on the side of the side pushing slider. The insert assembly is used to contact the driving block and push the side pushing slider to move.

[0010] Further, the insert assembly includes an insert and a guide seat;

[0011] On the opposite surfaces of the plug cutter and the side push slider, there are contact portions provided, and the contact portions are inclined surface structures;

[0012] Among them, the plug cutter is slidably connected between the guide seat side push slider.

[0013] Furthermore, a guide rod is movably inserted on the guide seat through a spring, and one end of the guide rod is connected to the side push slider;

[0014] Among them, the middle part of the plug cutter has an avoidance opening, and the guide rod slides in the avoidance opening.

[0015] Furthermore, a guide block is fixedly connected to the top of the lower die base through a fastener, and the avoidance opening is adapted to and slides with the guide block.

[0016] Furthermore, an upper stop block is fixedly installed on the top of the guide seat, a part of the upper stop block stops above the plug cutter, and a part of it is vertically offset from the driving block.

[0017] Furthermore, there is a notch on the side of the side push slider, and a contact head is slidably connected in the notch through a compression spring.

[0018] A novel plug cutter structure of a stamping die proposed by the present utility model has the beneficial effects that: in the present utility model, by changing the structural design of the plug cutter, the action of the plug cutter on the upper die inserting into the side push slider is removed, thereby eliminating the situation of local stress on the plug cutter, and effectively solving the problem of local stress in the traditional plug cutter structure;

[0019] Secondly, since the situation of local stress on the plug cutter is eliminated, the possibility of the plug cutter breaking and falling from the upper die is also eliminated, greatly improving the operation safety. Since the novel plug cutter structure scheme of the present can fundamentally solve the problem of excessive local stress on the plug cutter, it can also effectively improve the service life of the plug cutter.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Refer to Figures 2-4 For an embodiment of the present invention, specifically, it discloses a new type of insert knife structure for a stamping die. The insert knife structure includes an upper die holder 2 installed with an upper template 1; and a lower die holder 4 installed with a lower template 3. It should be noted that the lower template 3 and the lower die holder 4 are connected to move up and down in this embodiment, and specifically, they can be guided and matched through a guide rod and a spring. An inner support mechanism is also provided in the lower template 3, which is used to support the inner bent surface of the TV backplane by moving against the inclined ejector rod when the upper die holder 2 and the lower die holder 4 are closed. Its specific structure is the prior art and will not be elaborated here;

[0027] Among them, a driving block 5 is fixedly installed below the upper die holder 2, a side pushing slider 6 is slidably connected above the lower die holder 4, and an insert knife assembly 7 is also provided on the lower die holder 4 and on the side of the side pushing slider 6. The insert knife assembly 7 is used to contact the driving block 5 and push the side pushing slider 6 to move.

[0028] In some embodiments, the insert knife assembly 7 in the present invention includes an insert knife 71 and a guide seat 72, and the guide seat 72 is fixedly installed on the lower die holder 4;

[0029] Contact parts 77 are provided on the opposite surfaces of the insert knife 71 and the side pushing slider 6. The contact parts 77 are inclined surface structures, and the cooperation of the two inclined surface structures is used to realize the lateral driving of the side pushing slider 6 by the insert knife 71;

[0030] Among them, the insert knife 71 is slidably connected between the guide seat 72 and the side pushing slider 6.

[0031] On the basis of the above embodiment, in this embodiment, a guide rod 74 is movably inserted into the guide seat 72 through a spring 73, and one end of the guide rod 74 is connected to the side pushing slider 6;

[0032] Among them, an avoidance opening 711 is provided in the middle of the insert knife 71, and the guide rod 74 slides in the avoidance opening 711.

[0033] That is, in this embodiment, when working, when the upper die base 2 and the lower die base 4 are closed, the driving block 5 on the upper die base 2 abuts against the insert knife 71 to move it downward, and when the insert knife 71 moves downward, it abuts against the side push slider 6 to move horizontally, so as to realize the side stamping and bending operation of the TV back panel. Of course, after the stamping is completed, the upper die base 2 is separated from the lower die base 4, and under the action of the spring 73, the side push slider 6 moves backward and resets, thus completing the stamping operation.

[0034] Furthermore, in this embodiment, a clearance opening 711 is provided on the lower side of the inserting blade 71 , so that the inserting blade 71 can avoid the guide rod 74 during the upward and downward movement, so as to avoid interference in their movement.

[0035] Furthermore, in this embodiment, a guide block 75 is fixedly connected to the top of the lower die base 4 by a fastener, and the avoidance opening 711 is adapted to and slides with the guide block 75. Specifically, the guide block 75 described in this embodiment is used to guide the insertion movement of the inserting knife 71, and the fastener is set as a bolt.

[0036] In addition, an upper stop block 76 is fixedly installed on the top of the guide seat 72, a part of which stops above the inserting knife 71, and the part is vertically offset from the driving block 5. The vertically offset design is adopted to ensure that the driving block 5 can stably contact the inserting knife 71.

[0037] In some embodiments, the side of the side-pushing slider 6 in the utility model has a notch, and a contact head 62 is slidably connected to the notch through a compression spring 61. The elastic and telescopic contact head 62 is designed to achieve the stamping and bending stability of the low TV back panel. It should be noted that in this embodiment, a mounting hole is provided in the notch, and the compression spring 61 is installed in the mounting hole and can be retracted into the inner side of the mounting hole.

[0038] In summary, the present invention changes the structural design of the inserting knife 71, removes the action of the inserting knife 71 of the upper mold inserting into the side push slider 6, thereby eliminating the situation where the inserting knife 71 is subjected to local force, and effectively solves the problem of local force in the traditional inserting knife 71 structure;

[0039] Secondly, since the local force on the insert knife 71 is eliminated, the possibility of the insert knife 71 breaking and falling from the upper mold is also eliminated, which greatly improves the safety of operation. Since the new insert knife structure solution can fundamentally solve the problem of excessive local force on the insert knife, it can also effectively improve the service life of the insert knife.

[0040] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
