Abstract
Description
Technical Field
[0001] This utility model belongs to the field of testing devices, specifically relating to a die-cutting waste discharge testing device. Background Technology
[0002] Currently, waste discharge breakage is a frequent problem in die-cutting production. Therefore, in order to avoid material breakage during waste discharge, it is usually necessary to test the die-cutting waste before production to obtain the stress data of the die-cutting material under breakage, so as to provide process personnel with reference and effectively control the relevant parameters in the production process.
[0003] Existing testing devices generally use a method of fixing one end of the material and tightening the other end to conduct the test. By gradually increasing the tension at one end of the material until the material breaks, the tension value is recorded as a reference.
[0004] However, in actual testing, because the waste material bypasses the bottom roller and is continuously conveyed during die-cutting production, the position of the waste material contacting the bottom roller changes constantly as the waste material is conveyed. That is, the waste material is dynamic in actual working conditions, while the existing testing device is tested when the waste material is static. Obviously, the existing testing device cannot simulate the actual working conditions, thus affecting the accuracy and reliability of the test results. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved die-cutting waste discharge test device.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A die-cutting waste discharge testing device includes a clamping unit and a tension unit. The clamping unit includes a first clamp and a second clamp arranged at a distance from front to back. The material to be tested extends from front to back and is clamped on the first clamp and the second clamp from both ends respectively. The tension unit is used to drive the first clamp and the second clamp away from each other to apply tension to the material to be tested. The testing device also includes a dynamic simulation unit disposed between the first clamp and the second clamp. The dynamic simulation unit includes a moving part that reciprocates along the front-back direction and an abutting module disposed on the moving part and abutting the material to be tested to form a V-shaped moving part. The contact position between the material to be tested and the abutting module in the moving part reciprocates synchronously along the front-back direction with the movement of the moving part.
[0008] Preferably, the contact module extends along the width of the material to be tested.
[0009] Preferably, the length of the contact module is greater than or equal to the width of the material to be tested.
[0010] Preferably, the contact module contacts the material under test from bottom to top, forming a V-shaped moving part. Here, the dynamic simulation unit is located below the material under test to facilitate observation of the fracture by the tester. Furthermore, the structure is simple and easy to install and implement.
[0011] Preferably, the contact module is recessed from the top and forms a U-shaped groove extending along the width of the material to be tested. The V-shaped moving part includes a first section extending obliquely upward to one side of the U-shaped groove, a second section extending horizontally from one side of the U-shaped groove to the other side, and a third section extending obliquely downward from the other side of the U-shaped groove.
[0012] Furthermore, one side wall or opposite side walls of the U-shaped groove are formed with multiple comb teeth arranged side-by-side at intervals along the width of the material to be tested. As the tension increases, the corresponding part of the material to be tested deforms downward and is positioned between two adjacent comb teeth, forming a motion guide in the front-back direction during the movement of the moving part. Here, based on the three-segment V-shaped motion section, simulating the actual die-cutting waste removal process, while the waste material bypasses the bottom roller, the horizontal second segment and the cooperation of multiple comb teeth form a motion guide in the reciprocating motion, preventing the material from shifting laterally and detaching. In addition, during the gradual tensile deformation of the material, the gaps between the multiple comb teeth comb the material, keeping it flat to ensure that the material breaks under tension.
[0013] Preferably, multiple comb teeth are formed on the opposite side walls of the U-shaped groove, and the multiple comb teeth on both sides are aligned in the front-back direction.
[0014] Preferably, the testing device further includes two slide rails arranged side-by-side at intervals. The moving parts include sliders slidably connected to each slide rail and connecting rods vertically connected to each slider. Each connecting rod is adjustable up and down, and an abutment module is fixedly connected between the tops of the two connecting rods. Here, the V-angle of the V-shaped moving part is adjusted by extending and retracting the connecting rods to simulate different working conditions.
[0015] Preferably, the first clamp is fixedly installed, the second clamp is slidably connected to the slide rail, and the tension unit is connected to the second clamp and drives the second clamp to move towards or away from the first clamp.
[0016] In addition, the first clamp and the second clamp each include a seat rod that is arranged side by side and extends vertically, a pressure rod and a bottom rod that are connected between the two seat rods and arranged vertically. The inner wall of each seat rod forms a vertically extending guide groove. The pressure rod is inserted into the corresponding guide groove from both ends and can be adjusted downward to press the end of the material to be tested against the bottom rod or adjusted upward to release the end of the material to be tested.
[0017] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:
[0018] During die-cutting production, waste material bypasses the bottom roller and continues to be conveyed. The contact position between the waste material and the bottom roller changes constantly as the waste material is conveyed, meaning the waste material is dynamic in actual working conditions. However, existing testing devices test the waste material when it is static. Obviously, existing testing devices cannot simulate actual working conditions, thus affecting the accuracy and reliability of test results. This application redesigns the structure of the die-cutting waste removal testing device, cleverly solving the shortcomings and defects of existing technologies. With this testing device, the two ends of the material to be tested are clamped on the first clamp and the second clamp, respectively. The contact module forms a V-shaped moving part by contacting the material to be tested. The tension unit drives the first clamp and the second clamp to move away from each other to apply pressure to the material to be tested. At the same time, the moving part is driven by motorized or manual operation, which drives the contact module to move back and forth. This causes the contact position between the material to be tested and the contact module in the moving part to change synchronously along the back and forth direction with the movement of the moving part, simulating the continuous conveyance of material bypassing the bottom roller in actual waste removal. Finally, the pressure is gradually increased until the material to be tested breaks. The pressure value is recorded to complete the test. Therefore, compared with the prior art, this utility model has two advantages. First, it is based on the dynamic simulation of die-cutting waste removal under actual working conditions by the reciprocating motion of the moving part under the contact between the contacting part and the material to be tested, which effectively improves the accuracy and reliability of the test results. Second, it has a simple structure and is convenient to operate. Attached Figure Description

[0033] Combination Figures 1 to 3 As shown, the die-cutting waste discharge test device of this embodiment includes a clamping unit 1, a tensile unit 2, and a dynamic simulation unit 3.
[0034] Specifically, the clamping unit 1 includes a first clamp 11 and a second clamp 12 arranged at a distance from front to back. The material to be tested M extends from front to back and is clamped from both ends to the first clamp 11 and the second clamp 12 respectively.
[0035] For ease of implementation, the testing device in this embodiment also includes two slide rails 4 arranged side by side on the testing machine platform and extending front to back. The first clamp 11 is fixedly installed, and the second clamp 12 is slidably connected to the slide rail 4. The tension unit 2 is connected to the second clamp 12 and drives the second clamp 12 to move closer to or away from the first clamp 11. The tension unit 2 is used to drive the first clamp 11 and the second clamp 12 to move away from each other to apply tension to the material M to be tested. The tension unit 2 can be any conventional tension testing machine.
[0036] In some specific embodiments, the first clamp 11 and the second clamp 12 have similar structures. The first clamp 11 and the second clamp 12 respectively include a seat body a0, seat rods a1 arranged side by side on the seat body a0 and extending vertically, a pressure rod a2 connected between the two seat rods a1 and arranged vertically, and a bottom rod a3. The seat body a0 in the first clamp 11 is fixedly installed, and the seat body a0 in the second clamp 12 is slidably connected to the slide rail 4. The tension end of the tension unit 2 is connected to the seat body a0 in the second clamp 12. The inner wall of each seat rod a1 forms a vertically extending guide groove a10. The two ends of the bottom rod a3 are fixedly connected to the seat rod a1. The pressure rod a2 is inserted into the corresponding guide groove a10 from both ends and can be adjusted downward by bolts to press the end of the material to be tested M against the bottom rod a3 or adjusted upward to loosen the end of the material to be tested M.
[0037] In this example, the dynamic simulation unit 3 is disposed between the first clamp 11 and the second clamp 12. The dynamic simulation unit 3 includes a moving part 30 that reciprocates along the front-back direction and a contact module 31 disposed on the moving part 30 and abutting against the material to be tested to form a V-shaped moving part b. The contact position between the material to be tested M and the contact module 31 in the moving part b changes synchronously along the front-back direction as the moving part 30 moves.
[0038] In some specific embodiments, the moving component 30 includes a slider 300 correspondingly slidably connected to each slide rail 4 and a connecting rod 301 vertically connected to each slider 300. The movement of the slider 300 is driven manually or by a conventional power source. Each connecting rod 301 is a telescopic rod and can be adjusted vertically. The abutment module 31 is fixedly connected between the tops of the two connecting rods 301. Here, the V-angle of the V-shaped moving part is adjusted by the vertical telescopic adjustment of the connecting rods to simulate and match different working conditions.
[0039] Meanwhile, the contact module 31 extends along the width of the material under test M, and the length of the contact module 31 is greater than or equal to the width of the material under test M. The contact module 31 contacts the material under test M from bottom to top and forms a V-shaped moving part b. Here, the dynamic simulation unit is located below the material under test to facilitate the tester's observation of the fracture. At the same time, the structure is simple and easy to install and implement.
[0040] In addition, the contact module 31 is recessed from the top and forms a U-shaped groove c that extends along the width of the material to be tested. The V-shaped moving part b includes a first section b1 that extends obliquely from bottom to top to one side of the U-shaped groove c, a second section b2 that extends horizontally from one side of the U-shaped groove c to the other side, and a third section b3 that extends obliquely downward from the other side of the U-shaped groove c.
[0041] To further facilitate implementation, one side wall or opposite side walls of the U-shaped groove c are formed with multiple comb teeth c0 arranged side-by-side at intervals along the width direction of the material M to be tested. As the tension increases, the corresponding part of the material M to be tested deforms downward and is positioned between two adjacent comb teeth c0, forming a motion guide in the front-back direction during the movement of the moving part 30. Here, based on the three-segment V-shaped motion part, simulating the actual die-cutting waste removal process where the waste material bypasses the bottom roller, the horizontal second segment and the cooperation of multiple comb teeth form a motion guide in the reciprocating motion, preventing the material from shifting laterally and detaching. In addition, during the gradual tensile deformation of the material, the gaps between the multiple comb teeth comb the material, keeping it flat to ensure that the material breaks under tension.
[0042] Specifically, multiple comb teeth c0 are formed on the opposite side walls of the U-shaped groove c, and the multiple comb teeth c0 on both sides are aligned in the front-back direction; at the same time, the top surface of each comb tooth c0 is a plane.
[0043] In summary, using this testing device, the two ends of the material to be tested are clamped onto the first clamp and the second clamp, respectively. The contact module forms a V-shaped moving part by contacting the material to be tested. The tension unit drives the first clamp and the second clamp to move away from each other to apply pressure to the material to be tested. At the same time, the moving part is driven by motor or manual operation, which drives the contact module to move back and forth. This causes the contact position between the material to be tested and the contact module in the moving part to change synchronously along the back and forth direction with the movement of the moving part, so as to simulate the working condition of material continuously being transported around the bottom roller in actual waste discharge. Finally, the pressure is gradually increased until the material to be tested breaks. The pressure value is recorded to complete the test. Therefore, compared with the prior art, this utility model has several advantages. First, it effectively improves the accuracy and reliability of test results by dynamically simulating the actual working conditions of die-cutting waste removal through the reciprocating motion of the moving parts under the contacting component and the material under test. Second, it has a simple structure and is easy to operate. Third, the dynamic simulation unit is located below the material under test, making it easier for testers to observe the fracture. Fourth, based on the three-section V-shaped motion section, it simulates the waste material bypassing the bottom roller in actual die-cutting waste removal. Through the cooperation of the horizontal second section and multiple comb teeth, a motion guide is formed in the reciprocating motion to prevent the material from shifting laterally and detaching. In addition, during the gradual stretching and deformation of the material, the gaps between the multiple comb teeth are used to comb the material to keep it flat and ensure that the material breaks under tension. Fifth, the V-shaped angle of the V-shaped motion section can be adjusted by the up-and-down extension and retraction of the connecting rod to simulate and match different working conditions.
[0044] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
