Description

Technical Field

[0001] The invention relates to the field of mold processing production equipment, and in particular to an adaptive quick-detachable waste guide rail and an operating method thereof. Background Art

[0002] In the mold manufacturing process, the generation of waste is inevitable. These wastes include metal waste, plastic waste, scraps, etc. The main goal of dealing with these wastes is to achieve resource recycling and reuse while reducing the impact on the environment. During mold stamping production, the stamping production auxiliary equipment has problems such as long matching time, inconvenient installation, and non-smooth material guiding process when connecting the waste guide rail, resulting in waste often accumulating in the rail. There is also a large clearance between the waste guide rail and the outer edge of the template. Therefore, waste is easily stuck in the gap during production, which eventually leads to mold abnormalities and other problems that become the main contradiction affecting production efficiency.

[0003] In order to further improve production efficiency, it is necessary to standardize and standardize the scrap linear guide rail. In order to achieve standardization and standardization, the scrap linear guide rail needs to be redesigned and processed to make it have a wide range of applications, reliable material guidance, and quick installation. The present invention provides an adaptive quick-detachable scrap guide rail and its operation method. Summary of the invention

[0004] (1) Technical issues to be resolved The present invention aims at the above-mentioned problems in the prior art and, in order to make up for the deficiencies of the prior art, provides an adaptive quick-detachable waste guide rail and an operating method thereof that can be reasonably manufactured and used.

[0005] (2) Technical solution In order to solve the above technical problems, the present invention provides an adaptive quick-detachable waste guide, including a linear guide installed above the work table of the punch press and on the waste discharge side of the mold, and a waste guide is provided on the linear guide. The receiving end of the waste guide is elastically pressed against the waste discharge end of the mold when in use.

[0006] Preferably, a slider is sleeved on the linear guide rail, the waste guide rail is installed above the slider, the outward side of the slider is pressed against by a preload spring, and the preload spring is also sleeved on the linear guide rail, so that the waste guide rail is pressed against the waste discharge end of the mold in real time through the preload spring; At least two linear guide rails are provided to effectively maintain the stability of the waste guide rail when it moves.

[0007] Preferably, the linear guide rail is horizontally installed above a support plate, and the support plate is detachably installed above a work surface of the punch press and on a side where mold waste is discharged.

[0008] Preferably, the linear guide rail fixing seat is locked on the support plate by a first fixing screw, and the linear guide rail is sleeved in the middle of the linear guide rail fixing seat; At least two linear guide rail fixing seats are provided on one linear guide rail for limiting. The two linear guide rail fixing seats are provided to improve the convenience of installation. Of course, the linear guide rail fixing seats can also be installed on a large fixed plate near the mold waste discharge end.

[0009] Preferably, the end of the support plate facing the mold waste discharge is assembled with the fixed plate, the fifth fixing screw is screwed in from bottom to top to assemble the support plate and the fixed plate into one piece, and the fixed plate is locked on the outward side of the mold lower mold base by the fourth fixing screw. Preferably, a plunger disposed vertically upward is mounted in the middle of the slide block, a connecting platform is disposed on the plunger, the connecting platform and the plunger are perpendicular to each other, and the connecting platform is disposed toward one side of the mold.

[0010] Preferably, a limit plunger is provided in the middle of the slider for resisting against the insert knife to maintain verticality, and the intersection surface of the slider and the insert knife is arranged in a slanted downward closing shape. By providing the limit plunger, the risk of the component driven by the insert knife slipping during the waste collection process can be prevented, and when production is completed, it only takes a little more effort to pull it out.

[0011] Preferably, the limit plunger is cylindrical at one end facing outwards and has a funnel-shaped closing end facing inwards for pressing on the insert knife. A ball is provided at the end of the limit plunger that cooperates with the insert knife. The purpose of such a setting is, on the one hand, to effectively limit the insert knife, and on the other hand, the spherical surface can play a guiding role when the insert knife is inserted and removed, making it easy to enter and exit.

[0012] Preferably, the connecting platform is locked with the inserting knife by a second fixing screw, a hinge matching with the bottom of the waste guide rail is installed above the connecting platform, and a reinforcing plate is also provided between the hinge and the waste guide rail; At least two hinges are provided to facilitate a more stable waste conveying guide rail, and one side of the hinge is locked on the connecting platform by a third fixing screw.

[0013] Preferably, a power assist screw perpendicular to the moving direction of the slider is installed on the slider, and the length of the power assist screw extends to the outer end of the waste guide rail. The power assist screw extends to the outer end of the waste guide rail in order to better operate the waste guide rail.

[0014] Preferably, the waste guide rail is made of stainless steel. In order to reduce the impact on the processing between the molds, the end of the waste guide rail facing the mold waste discharge should be lower than the lowest height of the upper mold when the mold is processed. When in use, the waste guide rail is tilted to facilitate material guiding. In addition, the width of both sides of the non-material guiding end of the waste guide rail can be set to be greater than the width of the upper mold on the same side, thereby effectively wrapping the periphery of the mold, expanding the material guiding area, and avoiding material leakage, while not affecting the processing of the mold.

[0015] Preferably, the second fixing screw, the third fixing screw and the fourth fixing screw are installed in staggered positions and do not affect each other during use.

[0016] Preferably, the matching scheme of the fixing plate and the supporting plate can be replaced by an L-shaped plate structure.

[0017] The present invention also provides another solution, a method for operating an adaptive quick-detachable waste guide rail, comprising the following steps: S1. Assemble the linear guide assembly: fix the hinge, the reinforcement plate and the scrap guide together by argon arc welding, and integrate them with the connecting bridge and the insert by the second fixing screw and the third fixing screw, and open an opening with a diameter of 10.0 mm on the insert; S2. Assemble the preload mechanism, which includes a support plate, a linear guide rail, a linear guide rail fixing seat, a first fixing screw, a preload spring, a limit plunger, a slider, a fixing plate, and a fifth fixing screw. Assemble the above parts and debug them according to the size of the product; S3. After the above dimensions are adjusted, place the preload mechanism in the middle of the mold side, fix it to the lower mold base of the mold through the fourth fixing screw, hold the power screw installed on the slider with both hands, pull it back more than 10.0mm, then hold the power screw on one side with one hand to stop it, take the linear guide rail assembly with the other hand, align the insert knife with the limit hole of the slider and press it to the bottom with force. In order to prevent the linear guide rail assembly from slipping during the production process, after the assembly is completed, the opening on the insert knife is assembled with the limit plunger and limited by the limit plunger; S4. Press the rear section of the linear guide assembly, that is, press the part of the waste guide, so that the rear section of the linear guide assembly is close to the bottom of the punching machine worktable, and the installation is completed; During operation, the preloaded spring always transmits a certain thrust to the slider, causing the waste guide rail on the slider to abut against the waste discharge end of the mold. When the slider moves to the left, the linear guide rail assembly moves to the left until it abuts against the right side of the column mold board.

[0018] (3) Beneficial effects The present invention overcomes the problem that the gap between the waste guide rail and the outer edge of the mold in the prior art is too large, and waste is easily stuck in the gap during production, which leads to abnormal production and defective products. A horizontally arranged linear guide rail is installed on the lower mold base of the mold, and a guide rail assembly is matched on the linear guide rail, that is, a waste guide rail that can be elastically pressed on the waste discharge side of the mold. A preload spring is installed on the linear guide rail, so that the preload spring provides a continuous and certain preload force to the slider, so that it can drive the guide rail assembly to be elastically pressed on the waste discharge side of the mold, so that the waste guide rail and the mold discharge side are seamlessly fitted, and no waste is stuck or accumulated at the fitting place. In addition, since the height of the waste guide rail receiving end is higher, the waste guide rail has a larger inclination angle, and the waste flows out more smoothly. It is convenient, quick, safer, and more in line with the 5S specification when installed. During use, the preload spring pushes against the slider, and then the pressure is transmitted to the waste guide rail, so that the waste guide rail is pressed at the waste discharge place of the mold to automatically achieve the adaptation effect. At the same time, the present invention can be installed on molds of different sizes, and is applicable to a wide range of molds, and can be assembled in this form, and has strong applicability; by using the present invention to perform gapless matching during mold processing, the material guide is smoother. In addition, the parts contained in the present invention are relatively simple, convenient for processing and production, easy to achieve standardized processing, and can effectively reduce production costs and improve efficiency.

[0021] The present invention is further described in conjunction with the accompanying drawings and embodiments.

[0022] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "vertical", "horizontal", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] like Figure 1-8 As shown, the present invention provides an embodiment of an adaptive quick-detachable waste guide rail, including a linear guide rail 2 installed above the punching machine worktable 20 and on the waste discharge side of the mold, and a waste guide rail 11 is provided on the linear guide rail 2. When the waste guide rail 11 is processed, the fitter finds a suitable 0.2mm thick thick material strip according to the length of each set of molds, the width of the product, and the length of the punching machine worktable, and bends its two sides into U-shaped parts, and sets the height of the waste guide rail 11 according to the matching height of the mold to avoid the situation where the waste guide rail 11 is affected during stamping. In specific processing, a certain flat section can be left at the receiving end of the waste guide rail 11 to reduce the impact caused by stamping. The receiving end of the waste guide rail 11 is elastically pressed against the waste discharge end of the mold when in use. Specifically, it includes a linear guide assembly and a pre-tightening mechanism, wherein the linear guide assembly includes a hinge 10, a reinforcement plate 13 and a waste guide 11, the hinge 10, the reinforcement plate 13 and the waste guide 11 are fixed together by argon arc welding, one end of the hinge 10 is connected to the connecting platform 14 by a third fixing screw 15, and the plunger 9 is connected to the connecting platform 14 by a second fixing screw 8, so that the slider 7 can drive the plunger 9 and the parts above the plunger 9 to move when sliding, and the connecting platform 14 is locked with the plunger 9 by the second fixing screw 8, and the hinge 10 that cooperates with the bottom of the waste guide 11 is installed above the connecting platform 14, and a reinforcement plate 13 is further provided between the hinge and the waste guide 11, and at least two hinges 10 are provided, and one side of the hinge 10 is locked on the connecting platform 14 by a third fixing screw 15; The preload mechanism comprises a support plate 1, a linear guide rail 2, a linear guide rail fixing seat 3, a first fixing screw 4, a preload spring 5, a limit plunger 6, a slider 7, a fixing plate 17, and a fifth fixing screw 18. The above parts are assembled and debugged according to the size of the product. In order to maintain a stable waste guide rail 11 and smooth movement, the linear guide rail 2 is provided with at least two. The slider 7 is sleeved on the linear guide rail 2, and the waste guide rail 11 is installed above the slider 7. The outward side of the slider 7 (shown as the right side in the figure) is supported by a preload spring 5, and the preload spring 5 is also sleeved on the linear guide rail 2. The linear guide rail 2 is horizontally installed above the support plate 1. The support plate 1 is detachably installed above the punching machine worktable 20 and on the side where the mold waste is discharged. The support plate 1 is locked by screws from bottom to top. In order to facilitate the installation of the linear guide rail 2 , the linear guide rail fixing seat 3 is locked on the support plate 1 by the first fixing screw 4, and the linear guide rail 2 is sleeved in the middle of the linear guide rail fixing seat 3. In order to achieve aesthetics and balance, at least two linear guide rail fixing seats 3 are provided on one linear guide rail 2 for limiting. Of course, in specific practice, the linear guide rail fixing seat 3 on the left side (in the direction shown in the figure) can also be removed, and the fixing plate 17 can be extended to the front and rear ends, and holes and grooves for convenient installation of the linear guide rail 2 can be provided on the fixing plate 17. This is also feasible as a substitute solution. The end of the support plate 1 facing the waste material discharge of the mold is assembled with the fixing plate 17, and the fifth fixing screw 18 is screwed in from bottom to top to assemble the support plate 1 and the fixing plate 17 as a whole. The fixing plate 17 is locked on the outward side of the lower mold base 19 of the mold by the fourth fixing screw 16 to facilitate fixation; The middle part of the slide block 7 is equipped with a plunger 9 arranged vertically upward, and a connecting platform 14 is arranged on the plunger 9. The connecting platform 14 and the plunger 9 are perpendicular to each other, and the connecting platform 14 is arranged toward one side of the mold. The plunger 9 is driven by the slide block 7, and the plunger 9 drives the connecting platform 14, and then the connecting platform 14 drives the waste guide rail 11 above to be close to the waste discharge end of the mold. In order to realize the limit of the plunger 9, see the attached Figure 8 and 9 The middle part of the slider 7 is provided with a limit plunger 6 for resisting the inserting knife 9 to keep it vertical. The inserting knife 9 is provided with an opening with a diameter of 10.0 mm. The end of the limit plunger 6 cooperating with the inserting knife 9 is provided with a ball. When in use, the ball is inserted into the opening. The ball here can limit the inserting knife 9 on the one hand, and on the other hand, during the insertion and withdrawal of the inserting knife 9, the ball surface guides the inserting knife through the ball surface, which facilitates the entry and withdrawal of the inserting knife and realizes the assembly and quick release effect. The intersection surface of the slider 7 and the inserting knife 9 is set in an inclined downward closing shape, which also plays a good limiting effect. See attached for details Figure 7In order to facilitate the control of the slider 7, an assist screw 12 perpendicular to the moving direction of the slider 7 is installed on the slider 7, and the length of the assist screw 12 extends to the outer end of the waste guide rail 11. In this way, the moving distance of the slider 7 can be controlled by the outer assist screw 12 during use, thereby indirectly pulling the waste guide rail 11 to move outward. During use, the present invention is committed to making the waste guide rail 11 seamlessly abut against the waste discharge end of the mold.

[0024] It should be noted that the parts in this solution are all disassembled and simplified structures in order to facilitate the early assembly and subsequent quick disassembly. For example, the fixing plate 17 and the support plate 1 can be directly replaced by an L-shaped plate structure, which has no effect. However, since the L-shaped plate processing is more complicated in actual operation, it is easier to realize standardized production by splitting it into several simple structural parts.

[0025] The operation process of this adaptive quick-release waste guide is divided into the following steps: 1. Assemble the linear guide assembly The hinge 10, the reinforcing plate 13 and the waste guide rail 11 are fixed together by argon arc welding, and the second fixing screw 8 and the third fixing screw 15 are used to form an integral body with the connecting bridge 14 and the inserting knife 9, and an opening with a diameter of 10.0 mm is opened on the inserting knife 9; 2. Assemble the preload mechanism The preload mechanism is composed of a support plate 1, a linear guide rail 2, a linear guide rail fixing seat 3, a first fixing screw 4, a preload spring 5, a limit plunger 6, a slider 7, a fixing plate 17, and a fifth fixing screw 18, and is adjusted according to the size of the product; 3. Assemble the above structure with the mold and stamping workbench After the above dimensions are adjusted, place the pre-tightening mechanism in the middle of the mold side, fix it to the mold lower die seat 19 through the fourth fixing screw 16, hold the power-assisting screw 12 installed on the slider 7 with both hands, pull it back by more than 10.0 mm, then hold the power-assisting screw 12 on one side with one hand to stop it, take the linear guide rail assembly with one hand, align the insert knife with the limiting hole of the slider and press it to the bottom with force, in order to prevent the linear guide rail assembly from slipping during the production process, after the assembly is completed, the opening on the insert knife 9 is assembled with the limiting plunger 6 and limited by the limiting plunger 6; Press the rear section of the linear guide assembly, that is, press the part of the waste guide, so that the rear section of the linear guide assembly is close to the bottom of the punch press worktable, and the installation is completed.

[0026] During operation, the preload spring 5 always transmits a certain thrust to the slider 7, causing the waste guide rail 11 on the slider 7 to abut against the waste discharge end of the mold. When the slider 7 moves to the left, the linear guide rail assembly moves to the left until it abuts against the right side of the column mold board.

[0027] During specific use, after the mold on the stamping workbench is punched, the waste is cut and ejected from the waste discharge end, and then seamlessly guided to the waste guide rail 11 receiving end. Since the waste guide rail 11 is inclined, the waste can be smoothly sent out from the waste guide rail 11, and this solution can effectively cooperate with different molds and has strong applicability. In addition, it should be noted that the present invention has a quick-release function. Since each part has a standard and standardized size, it is simpler to assemble than special-shaped parts during the installation process, so it is also simpler to disassemble. It has the function of automatically adapting to the waste discharge end of the pressing mold and the quick-release effect of standardized parts.

[0028] The above embodiments only express the preferred embodiments of the present invention, and the description thereof is relatively specific and detailed, but the present invention is not limited to these embodiments. It should be noted that it is obvious to those skilled in the art.
