Description

Technical Field

[0001] This invention belongs to the technical field of terminal cutting devices, and particularly relates to a terminal cutting device that cuts and picks up materials from bottom to top. Background Technology

[0002] In the field of metal processing, especially for the cutting of double-strip terminals, existing processes generally adopt a top-down cutting method (that is, using the up-and-down movement of the cutting tool to cut the terminal strip) to cut the terminal with double strips into a single terminal with a small section of strip attached in one go. However, this cutting method has gradually revealed a series of problems in practice, which have adversely affected processing quality and efficiency.

[0003] Firstly, the top-down cutting method often produces a lot of burrs during the cutting process due to the direct collision and friction between the cutting tool and the metal part. These burrs not only seriously affect the appearance quality of the metal part, but may also cause unnecessary interference to subsequent processing steps, such as pin insertion, and may even negatively affect the performance of the entire product.

[0004] Secondly, when it is necessary to cut a double-stripe terminal into a single terminal with a small strip attached in one step, the existing method still faces the problem of stress concentration at the connection point of the double-stripe. Because the material strength at the connection point of the double-stripe is relatively high, the cutting tool is prone to generating significant stress and deformation in this area during cutting, resulting in noticeable deformation of the cut metal part at this location. 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] Secondly, the individual terminals formed after cutting, each connected to a small section of material strip, usually fall haphazardly into the product box, making it difficult to retrieve them one by one.

[0006] Therefore, the inventors dedicated themselves to designing a cutting die to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a terminal cutting device that cuts and picks up materials from bottom to top, which can not only reduce the generation of burrs, but also reduce the stress concentration phenomenon at the connection of double strips, thereby improving the cutting quality and production efficiency of metal parts, and facilitating material picking and subsequent production processes.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0009] A terminal cutting device for bottom-up cutting and material handling includes a base, an upper mold fixedly supported above the base, and a lower mold with vertical movement function located directly below the upper mold. The lower mold and the upper mold are joined to form a feeding channel. A connecting cutter and a pair of strip cutters are sequentially fixedly installed on the mating surface of the upper mold along the feeding direction of the feeding channel. A pressure block for pressing the strip is slidably and elastically connected in a sliding hole on the side of the feeding channel. A pressing element for pushing the pressure block away from the strip is vertically and movably connected to the pressure block. The component passes through the upper mold and is elastically connected to the upper mold. The top of the upper mold is provided with a material picking hole, which is located between the same pair of strip cutters and communicates with the feeding channel. Above the material picking hole is a material picking block for pressing down the pressing component and taking out a single strip product from the material picking hole. The mold closing surface of the lower mold is provided with a waste discharge hole at the position opposite to the strip cutter. A waste pipe is fixed on the discharge side of the upper mold. The waste discharge hole is connected to the waste pipe through the waste pipe. The discharge port at the end of the feeding channel is located on the side wall of the waste pipe.

[0010] As an improvement of the terminal cutting device of the present invention for cutting and picking up materials from bottom to top, the bottom of the picking block is provided with a picking column for extending into the picking hole to pick up materials, and the bottom of the picking column is provided with a picking suction nozzle.

[0011] As an improvement of the terminal cutting device of the present invention for cutting and picking up materials from bottom to top, a slide plate is slidably connected to the bracket next to the base, and a slide block is slidably connected to the slide plate. The picking block is vertically moved and arranged on the slide block.

[0012] As an improvement of the terminal cutting device of the present invention for cutting and picking up materials from bottom to top, the feeding end of the lower die is provided with a feeding plate, and a feeding wheel for feeding the material strip to be cut is vertically and rotatably passed through the feeding plate. The outer wall of the feeding wheel is provided with a plurality of wheel teeth for cooperating with the positioning holes of the material strip to be cut.

[0013] As an improvement of the terminal cutting device for bottom-up cutting and material picking of the present invention, the pressing member includes a pressing column and a wedge block. The wedge block is elastically mounted on the mold closing surface of the upper mold. The wedge block is located between the same pair of strip cutters and is movably connected to the pressing block. The pressing column is arranged on the top of the wedge block along the axial direction of the wedge block.

[0014] As an improvement of the terminal cutting device of the present invention for cutting and picking up materials from bottom to top, the wedge block is arranged perpendicularly to the pressure block, the lower end of the wedge block is inclined to form an inclined surface away from the feeding channel, and the pressure block is provided with an insertion hole for the lower end of the wedge block to be inserted.

[0015] As an improvement of the terminal cutting device of the present invention for cutting and picking up materials from bottom to top, the wedge block is T-shaped, the upper end of the wedge block is inserted into the upper mold and its two shoulders are elastically connected to the upper mold through pressing springs, and the pressing column passes vertically through the upper mold and extends out of the upper mold.

[0016] As an improvement of the terminal cutting device of the present invention for cutting and picking up materials from bottom to top, the lower mold includes a lower template, a panel and a base plate. The lower template is located above the panel, and the base plate is fixed to the bottom of the panel and elastically connected to the lower template through a lower mold spring.

[0017] As an improvement of the terminal cutting device of the present invention for cutting and picking up materials from bottom to top, the base plate is vertically fixed with a product top column for supporting the product and two material strip top plates for supporting the two material strips. The product top column and the two material strip top plates pass through the panel and the lower template.

[0018] As an improvement of the terminal cutting device of the present invention for cutting and picking up materials from bottom to top, the number of continuous material cutters is multiple and they extend into the same feeding channel. The lower template is provided with multiple waste holes in the position of the continuous material cutters. The panel and the bottom plate are provided with a waste outlet hole. All the waste holes are connected to the waste outlet hole to form the waste discharge hole.

[0019] Compared with the prior art, the terminal cutting device of the present invention, which cuts and picks up materials from bottom to top, installs a connecting cutter and a pair of strip cutters on the upper mold. By moving the lower mold up and down, it cuts from bottom to top, achieving stable and accurate cutting of the two strips of metal parts. At the same time, the connecting cutter first cuts the connecting part of the two strips, and then the pair of strip cutters cuts the area near the strip of the product to form a single connecting strip product for secondary cutting. This reduces the stress concentration at the connection of the two strips, thereby improving the cutting quality and production efficiency of the metal parts. After cutting, the picking block presses down on the pressing part to make the pressing block detach from the strip. The picking block smoothly picks up the single connecting strip product that has been cut in the picking hole, which facilitates the subsequent production process. Attached Figure Description

A wedge block 4 is perpendicular to the pressure block 44 and is used to push the pressure block 44 away from the material strip. 4 is located between the same pair of strip cutters 25 and is movably connected to the pressure block 44. Specifically, the side of the pressure block 44 is L-shaped and is limited and matched with the limiting groove at the bottom of the sliding hole 51. The pressure block 44 is provided with an insertion hole 441 for the lower end of the wedge block 4 to be inserted. The side of the pressure block 44 away from the feeding channel 5 is elastically connected to the lower template 31 by two springs. In this embodiment, the number of connecting cutters 24 in the same feeding channel 5 is preferably two, so that the two connecting cutting parts 61 of the strip to be cut can be cut at the same time. The lower ends of the two connecting cutters 24 extend into the same feeding channel 5. The lower template 31 is provided with two waste holes 36 in the position directly opposite the connecting cutters 24. The panel 32 and the bottom plate 33 are provided with a waste outlet hole 361. The waste outlet hole 361 is located directly below the two waste holes 36. All waste holes 36 and waste outlet holes 361 are connected to form the waste discharge hole 362.

The lower mold 3 is guided and connected to the upper mold 2 through all the guide pillars 26. The discharge side of the upper mold 2 is fixed with a waste pipe 12. The lower mold 3 is driven to move up and down by an upward push cylinder 14. The upward push cylinder 14 is located directly below the lower mold 3. The entire lower mold 3 is set at the output end of the upward push cylinder 14. The upward push cylinder 14 is fixed on a base 1. The base 1 is supported and connected to the upper mold plate 22 through multiple fixed pillars 11. All the fixed pillars 11 are arranged around the lower mold 3.

The discharge port at the end of the feeding channel 5 is located on the side wall of the waste pipe 12 so that the waste in the feeding channel 5 can fall directly into the waste pipe 12.

[0043] Reference Figures 1 to 4The lower die 3 has a feeding plate 8 at its feeding end. A feeding wheel 811 for feeding the strip 6 to be cut is vertically and rotatably mounted on the feeding plate 8. The outer wall of the feeding wheel 811 is provided with a plurality of gear teeth for cooperating with the positioning holes of the strip 6 to be cut. A feeding motor 81 is provided on the side of the feeding plate 8, and the feeding wheel 811 is located on the output shaft of the feeding motor 81.

[0044] Reference Figure 1 A sliding plate 73 is slidably connected to a bracket on the side of the base 1. A horizontal linear module 721 is provided on the bracket. The sliding plate 73 is located on the horizontal linear module 721. A sliding block 72 is slidably connected to the sliding plate 73. A vertical cylinder 722 is fixed at the upper end of the sliding plate 73. The sliding block 72 is located at the output end of the vertical cylinder 722. A longitudinal cylinder 723 is fixed on the sliding block 72.

The bottom of the material picking block 7 is provided with a material picking column 71 for extending into the material picking hole 23 to pick up material. The bottom of the material picking column 71 is provided with a material picking suction nozzle 711.

[0045] Reference Figures 1 to 6 To improve the cutting efficiency of the mold in this invention, the lower mold 3 and the upper mold 2 are joined to form multiple feeding channels 5. Preferably, two feeding channels 5 are used, spaced apart, and each can hold a single strip of material to be cut 6. The connecting cutter 24, the strip cutter 25, and the wedge block 4 on the two feeding channels 5 have the same structure and position, allowing for simultaneous cutting of two strips of material 6. The upper mold 2 has two waste pipes 12 on its discharge side, and the lower mold 3 has two waste discharge holes 362 at its bottom, which are connected to the waste pipes. 13 is connected to the two waste pipes 12 one by one. On the two feeding channels 5, the waste generated by the connecting cutter 24 can enter the waste pipe 12 through the corresponding connecting waste pipe 13. The waste generated at the outlet of the two feeding channels 5 can directly enter the corresponding waste pipe 12. There are also two feeding wheels 811, which are controlled by different feeding motors 81 to feed the two strips 6 to be cut separately. There are two picking columns 71 at the bottom of the picking block 7, which can be inserted into the two picking holes 23 respectively and suck out the corresponding connecting strip products 63.

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

[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 engage with the positioning holes of the strips 6 to be cut.

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

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

[0050] Press down the pressing column 43, compress the pressing spring 42, and the wedge block 4 moves down and inserts into the insertion hole 441 of the pressing block 44, forcing the pressing block 44 to move outward and detach from the material belt of the connecting strip product 63. At this time, the connecting strip product 63 is supported on the product top column 34.

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

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

[0053] The material strip 6 to be cut moves further forward, and together with the waste strip formed after being cut by the connecting material cutter 24, it is pushed from the outlet of the feeding channel 5 into the waste pipe 12, and finally into the waste bin.

[0054] In the mold cutting process of the present invention, the four cutting blades (i.e., two connecting material cutting blades 24 and two strip cutting blades 25) cut simultaneously. Due to the different positions of the four cutting blades, the cutting order of different parts on the strip 6 to be cut is different. That is, first, the two adjacent connecting material cutting parts 61 on the strip 6 to be cut are cut to separate the connecting parts of the two strips. Then, the strip cutting parts 62 on both sides of the terminal strip are cut off, so that a single connecting strip product 63 can be separated, which is convenient for the subsequent work station to insert the terminal.

[0055] The terminal cutting device of the present invention, which cuts and picks up materials from bottom to top, installs a connecting material cutter 24 and a pair of strip cutting blades 25 on the upper mold 2. By moving the lower mold 3 up and down, it cuts from bottom to top, realizing stable and accurate cutting of the double strips of metal parts. At the same time, the connecting material cutter 24 first cuts the connecting part of the two strips, and then the pair of strip cutting blades 25 cuts the strips near the product to form a single connecting strip product 63, performing a second cutting to reduce the stress concentration at the connection of the two strips, thereby improving the cutting quality and production efficiency of metal parts. After cutting, the picking block 7 presses down on the pressing member 45 to make the pressing block 44 detach from the strip, and the picking block 7 smoothly takes out the cut single connecting strip product 63 from the picking hole 23, which facilitates the subsequent pin insertion production.

[0056] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Therefore, any equivalent variations made in accordance with the scope of the patent application of the present invention are still within the scope of the present invention.
