Description
Technical Field
[0001] This utility model belongs to the field of connecting strip processing technology, and in particular relates to a product end heat shrink tubing cutting device. Background Technology
[0002] (Flexible and rigid) connectors are high-current conductive devices widely used in electrical engineering. They are mainly used for current transmission and connection in power distribution systems, new energy equipment, and industrial fields. Their main materials include aluminum and copper. In the production process of copper connectors, rigid connector ends (usually conductive metals, such as iron) are fixed at both ends for connection. Functional protective sleeves (such as fireproof braided sleeves) are fitted on the copper connectors. Heat shrink sleeves are fitted on the rigid connector ends and heat shrink them to achieve the function of tightening the protective sleeves in the aforementioned process onto the copper connectors (while also achieving waterproofing at the ends).
[0003] Due to the soft nature of heat shrink tubing, it is usually required to be manually fitted when used with connecting strips, especially flexible connecting strips. The fitting must ensure that there is enough allowance at the ends. In order to ensure that the connection at the ends is not affected, a corresponding cutting and removal process is required. Currently, the conventional cutting process is to manually control the cutting blade to cut the two wide sides of the hard connecting end, and then manually remove the excess heat shrink tubing by cutting or tearing the two narrow sides with a knife.
[0004] The above processing steps are mainly done manually for cutting and removing parts, which is quite cumbersome. Therefore, a more automated solution is needed to improve production efficiency and reduce labor costs. Utility Model Content
[0005] The purpose of this invention is to provide a product end heat shrink tubing cutting device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, one technical solution adopted by this utility model is: a product end heat shrink tubing cutting device, including a worktable and a lower blade, an upper blade, a left blade and a right blade, wherein the lower blade is disposed on the worktable; The workbench is equipped with drive component one and drive component two; The first drive component is used to control the upper blade to move closer to or away from the lower blade, and the second drive component is used to control the left blade and the right blade to move closer to or away from each other. The workbench is also equipped with a length positioning fixture. After the connecting end of the product extends into and abuts against the length positioning fixture from the lower blade, upper blade, left blade and right blade, the drive component one and drive component two move and realize the cutting of the heat shrink sleeve.
[0007] Preferably, a guide post is provided on the worktable along the direction of the upper blade movement, a guide block slides on the guide post, and the upper blade is mounted on the guide block.
[0008] Preferably, an elastic buffer is fitted on the guide post, and the guide block will compress the elastic buffer when it slides along the guide post toward the downward blade.
[0009] Preferably, the worktable is further provided with an adjustable limiting member, and the guide block has a limiting part that can abut against the adjustable limiting member. When the limiting part abuts against the adjustable limiting member, the maximum stroke of the drive assembly is reached.
[0010] Preferably, the adjustable limiting component includes a limiting bolt disposed on the worktable and a limiting nut threaded thereon, wherein the limiting part abuts against the limiting nut to prevent the travel from exceeding the limit.
[0011] Preferably, both the second driving component and the length positioning fixture are mounted on a moving platform; The worktable is equipped with a drive assembly three to control the moving table to move closer to or away from the cutting tool, so as to realize the pulling action of the heat shrink sleeve after cutting.
[0012] Preferably, the workbench is provided with a discharge channel, and the heat shrink sleeve pulled down can fall along the discharge channel. A receiving box / waste conveyor belt is provided below the discharge channel.
[0013] Preferably, the second drive assembly includes a drive cylinder that controls the movement of the left and right blades respectively.
[0014] Preferably, the length positioning fixture has an L-shaped cross-section, and the connecting end of the product overlaps on the horizontal section of the length positioning fixture. A side stop is provided on the horizontal section of the length positioning fixture. The horizontal section of the length positioning fixture is set to face the processing personnel, and the left hand of the operator is set as the left side. The side stop is set on the left side of the horizontal section of the length positioning fixture to achieve positioning of the left side of the connecting end of the product.
[0015] The beneficial effects of this utility model are as follows: This solution achieves the positioning of the product connection end by setting a length positioning fixture, and then the upper blade, left blade and right blade are driven by drive component one and drive component two respectively to achieve the cutting of the heat shrink sleeve. This process realizes the automatic cutting of the side of the heat shrink sleeve, which effectively improves production efficiency. By setting guide posts and guide blocks, the stability of the upward tool running direction is ensured; Among them, by setting up an elastic buffer, the jerking sensation of the upper blade running is reduced, and the stability of the cutting effect is improved; In order to reduce the wear of the upper tool and avoid damage to the workpiece, it is necessary to control the maximum stroke of the upper tool. The maximum stroke of the upper tool is limited by setting an adjustable limit component. With its adjustable performance, the device of this solution can also quickly adjust the limit position of the maximum stroke of the upper tool when facing the end of the product with different thicknesses. Among them, by setting the third drive component, the equipment in this solution can realize the pulling and detaching action of the cut heat shrink sleeve, further improving the processing efficiency; The design of the side stop on the length positioning fixture can further improve the positioning effect. The way it is set on the left side is based on the worker's (right-handed) feeding habit. Based on daily user feedback, since the positioning fixture is set inside, it is not easy to observe and thus difficult to position because there are stops on both sides. If the side stop is installed on the right side, the person's wrist will bend backward during positioning, and the backward perception is not strong, thus affecting the positioning effect.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0018] Example: See Figure 1-4 A product end heat shrink tubing cutting device includes a worktable 1 and a lower blade 7, an upper blade 6, a left blade 8 and a right blade 9, wherein the lower blade 7 is disposed on the worktable 1; The workbench 1 is provided with drive assembly 5 and drive assembly 14. The first drive assembly 5 is used to control the upper blade 6 to move closer to or away from the lower blade 7. The second drive assembly 14 is used to control the left blade 8 and the right blade 9 to move closer to or away from each other. Specifically, a column 2 and a guide column 3 arranged along the movement direction of the upper blade 6 are fixed on the worktable 1. A mounting base 4 is fixed on the guide column 3 and the guide block 10. The first drive assembly 5 is a cylinder and is fixed on the mounting base 4. A partition plate 21 is fixed on it to prevent personnel from touching the cylinder and causing burns. The guide block 10 slides on the guide column 3. The upper blade 6 is mounted on the guide block 10. The second drive assembly 14 includes a drive cylinder that controls the movement of the left blade 8 and the right blade 9 respectively.
[0019] The guide post 3 is fitted with an elastic buffer, which can be a spring. When the guide block 10 slides along the guide post 3 toward the lower cutter 7, it compresses the elastic buffer to buffer the stroke. The worktable 1 is also provided with an adjustable limiter. The guide block 10 has a limiting part that can abut against the adjustable limiter. When the limiting part abuts against the adjustable limiter, the maximum stroke of the drive assembly 5 is reached. Preferably, the adjustable limiter includes a limiting bolt fixed on the worktable 1 and a limiting nut threaded onto the limiting bolt. The limiting part abuts against the limiting nut to prevent the stroke from exceeding the limit.
[0020] The workbench 1 is also equipped with a length positioning fixture 16. The connecting end 19 of the product 18 extends into and abuts against the length positioning fixture 16 from the lower blade 7, upper blade 6, left blade 8 and right blade 9. The drive assembly 1 5 and drive assembly 2 14 move to cut the heat shrink sleeve 20. Specifically, the length positioning fixture 16 has an L-shaped cross-section. The connecting end 19 of the product 18 overlaps on the horizontal section of the length positioning fixture 16. A side stop 17 is provided on the horizontal section of the length positioning fixture 16. The horizontal section of the length positioning fixture 16 is set to face the operator. The operator's left hand is set to the left side. The side stop 17 is set on the left side of the horizontal section of the length positioning fixture 16 to achieve positioning of the left side of the connecting end 19 of the product 18.
[0021] The drive assembly 14 and the length positioning fixture 16 are both mounted on a moving stage 11, which slides on a guide rail 12. The worktable 1 is equipped with a drive assembly 13 to control the moving stage 11 to move closer to or away from the cutting blade 7, so as to realize the pulling action of the heat shrink sleeve 20 after cutting. The drive assembly 13 can be a cylinder mounted on the worktable 1.
[0022] The workbench 1 is provided with a material discharge channel 15, and the heat shrink sleeve 20 pulled down can fall along the material discharge channel 15. A material collection box / waste conveyor belt is provided below the material discharge channel 15 to collect the waste material after cutting.
[0023] Working principle and process: When using the equipment in this solution, the user manually picks up the product 18 and places it onto the length positioning fixture 16 based on experience until it contacts its vertical section. For equipment with side stops 17, lateral movement is then performed. The equipment is then started, and drive assembly 1 5 and drive assembly 2 14 drive the upper cutter 6, left cutter 8, and right cutter 9 to move, thus attempting to cut the heat shrink tubing 20. Next, drive assembly 1 5 drives the upper cutter 6 to rise, and drive assembly 3 13 drives the left cutter 8 and right cutter 9 to pull the cut heat shrink tubing backward. After the heat shrink tubing separates from the product 18, it will fall along the feeding groove 15 under the action of gravity. Then, drive assembly 2 14 drives the left cutter 8 and right cutter 9 to move away from each other, and drive assembly 3 13 drives the length positioning fixture 16 to reset and wait for the next operation.
