Description

Technical Field

[0001] The invention belongs to the technical field of terminal cutting devices, and in particular relates to a terminal cutting device capable of cutting and taking materials from bottom to top. Background Art

[0002] In the field of metal processing, especially for the cutting of double-strip terminals, the existing process generally adopts a top-down cutting method (i.e., using the up and down movement of the cutting tool to achieve the cutting of the terminal strip) to cut the terminal with double strips once to form a single terminal with a small section of strip. However, this cutting method has gradually exposed a series of problems in practice, which has an adverse effect on processing quality and efficiency.

[0003] First, in the top-down cutting method, due to the direct collision and friction between the cutter and the metal part, more burrs are often generated during the cutting process. These burrs not only seriously affect the appearance quality of the metal part, but also may cause unnecessary interference to subsequent processing steps, such as pin insertion, and may even have a negative impact on the performance of the entire product;

[0004] Secondly, when it is necessary to cut the double-strip terminal into a single terminal with a small strip in one step, the existing method also faces the problem of stress concentration at the connection of the double strips. Since the material strength at the connection of the double strips is relatively high, the cutter is likely to produce large stress and deformation in this area during cutting, resulting in obvious deformation of the metal part after cutting. This deformation not only affects the dimensional accuracy and shape stability of the metal part, but may also cause difficulties in subsequent use and assembly;

[0005] Thirdly, the individual terminals with a small section of material strip formed after cutting usually fall into the product box in a disorderly manner, making it difficult to take out the materials one by one.

[0045] Reference Figures 1 to 6 In order to improve the cutting efficiency of the mold in the present invention, the lower mold 3 and the upper mold 2 are combined to form a plurality of feeding channels 5. The present invention preferably has two feeding channels 5, which are arranged at intervals and can be respectively loaded with a single strip of material to be cut 6. On the two feeding channels 5, the structure and position of the connecting cutting knife 24, the strip cutting knife 25, and the wedge block 4 are the same, so that two strips of material to be cut 6 can be cut at the same time. Two waste pipes 12 are provided on the discharge side of the upper mold 2, and two waste discharge holes 362 are provided at the bottom of the lower mold 3. The two waste discharge holes 362 are respectively connected to the waste pipes 12. 13 is connected with the two waste pipes 12 in a one-to-one correspondence.

The number of feeding columns 71 at the bottom of the feeding block 7 is two, which can be inserted into the two feeding holes 23 respectively and suck out the corresponding continuous material strip products 63.

[0046] Reference Figures 1 to 12 The working principle of the bottom-up cutting mold of the present invention is:

[0047] Manually insert the two strips 6 to be cut horizontally into the two feed slots of the feed plate 8, so that the teeth of the feed wheel 811 match the positioning holes of the strips 6 to be cut;

[0048] The two feeding motors 81 drive their respective feeding wheels 811 to rotate, thereby driving the two strips 6 to be cut to move forward, so that the strips 6 to be cut enter the mold from the entrance of the feeding channel 5;

[0049] The upward push cylinder 14 drives the bottom plate 33 and the panel 32 to move upward together, and elastically presses the lower template 31 upward, so that the lower mold 3 and the upper mold 2 are molded together. On the one hand, the two continuous material cutting knives 24 cut the two continuous material cutting parts 61 of the material strip 6 to be cut, and the waste generated by the cutting here enters the waste box from the respective waste holes 36 through the waste outlet holes 361, the continuous waste pipe 13, and the waste pipe 12 in sequence. On the other hand, the two material strip cutting knives 25 cut the material strip cutting parts 62 on both sides of the product to form a single continuous material strip product 63 (that is, a small section of material strip is connected to the metal terminal to facilitate the terminal insertion in the subsequent process);

[0050] The pressing column 43 is pressed down, the pressing spring 42 is compressed, the wedge block 4 moves down and is inserted into the insertion hole 441 of the pressing block 44, forcing the pressing block 44 to move outward and separate from the material belt of the material belt product 63. At this time, the material belt product 63 is supported on the product top column 34;

[0051] The transverse linear module 721 drives the slide plate 73 to slide transversely, and the slide seat 72, the vertical cylinder 722, the longitudinal cylinder 723 and the material taking block 7 move transversely together with the slide plate 73. The longitudinal cylinder 723 controls the longitudinal movement of the material taking block 7, so that the two material taking columns 71 are located directly above the two material taking holes 23. The vertical cylinder 722 drives the slide seat 72 to slide up and down, and the longitudinal cylinder 723 and the material taking block 7 move up and down together with the slide seat 72. The two material taking columns 71 at the bottom of the material taking block 7 extend into the two material taking holes 23 one by one, and the material taking nozzle 711 sucks away a single material belt product 63 from the material taking hole 23. The two material taking columns 71 move the sucked two material belt products 63 to the pin insertion station for the next station operation.

[0052] The lower die 3 is reset, the pressing column 43 is stopped, the wedge block 4 is reset, the pressing block 44 is reset, and is pressed again on the material strip 6 to be cut with the terminals connected thereto;

[0053] When the cut material strip 6 moves forward further, the waste material strip formed after cutting by the continuous material cutter 24 is pushed into the waste material pipe 12 from the outlet of the feeding channel 5 and finally enters the waste material box.

[0054] During the mold cutting process of the present invention, four cutters (i.e., two continuous material cutters 24 and two strip cutters 25) are cut synchronously. Due to the different positions of the four cutters, the cutting order of different parts on the strip 6 to be cut is different, i.e., first cut two adjacent continuous material cutting parts 61 on the strip 6 to be cut to separate the connecting parts of the two strips, and then cut the strip cutting parts 62 on both sides of the terminal strip, so that a single continuous material strip product 63 can be separated, which is convenient for the subsequent workstation to insert the terminals.

[0055] The terminal cutting device for cutting and taking materials from bottom to top of the present invention installs a continuous material cutter 24 and a pair of material strip cutters 25 on the upper mold 2, and uses the up and down movement of the lower mold 3 to cut from bottom to top, thereby realizing stable and accurate cutting of the double material strips of the metal part. At the same time, the continuous material cutter 24 is used to first cut the connecting part of the two material strips, and then the pair of material strip cutters 25 are used to cut the product near the material strip to form a single continuous material strip product 63, and then a secondary cutting is performed to reduce the stress concentration phenomenon at the connection of the double material strips, thereby improving the cutting quality and production efficiency of the metal part. After cutting, the pressing piece 45 is pressed down by the material taking block 7 to separate the pressing piece 44 from the material strip, and the material taking block 7 smoothly takes out the cut single continuous material strip product 63 in the material taking hole 23, which is convenient for the subsequent pin insertion production.

[0056] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention.
