Iron tooth trimming and shaping apparatus

Abstract

This application relates to the field of tooth cutting and shaping, and more particularly to a tooth cutting and shaping device, which includes a slide, a punch head, a first spring, and a stripper rod. The punch head is fixedly connected to the lower end of the slide, and the stripper rod is slidably connected to the outer wall of the slide. One end of the first spring is fixedly connected to the lower end of the slide, and the other end of the first spring is fixedly connected to one end of the stripper rod, the other end of which is used to abut against the workpiece. When the slide moves the punch head downward, the stripper rod abuts against the workpiece before the punch head and presses it tightly, and the first spring is compressed and stores energy. As the slide continues to move downward, the punch head completes the punching and separation. When the slide moves upward during its return stroke, the first spring releases its stored energy and pushes the stripper rod downward relative to the slide, pushing away any waste material that may be stuck to the outer ring of the punch head, thus achieving automatic unloading. By slidably connecting the stripper rod to the outer wall of the slide and directly connecting the first spring between the lower end of the slide and the stripper rod, the need for an external frame or additional support components is eliminated, simplifying the overall structure of the equipment and reducing manufacturing costs.

Description

Technical Field

[0001] This application relates to the field of iron tooth cutting edge shaping, and in particular to an iron tooth cutting edge shaping device. Background Technology

[0002] Toothed edge forming is a commonly used forming equipment in the metal processing industry. It uses a punch head to press down on a workpiece placed on a processing table, separating the workpiece into different parts. In toothed edge forming using a compound die structure, after one punching, the middle part of the workpiece falls off from the unloading port of the processing table, while the outer ring part must remain on the processing table for the operator to remove and replace with a new workpiece. To ensure the continuity and efficiency of the punching process, the outer ring part must reliably detach from the punch head and remain on the processing table during the return stroke of the punch head.

[0003] However, in actual production, during the return stroke of the stamping head, due to vacuum adsorption, plastic deformation of the material, etc., the outer ring often sticks to the stamping head and rises with it, failing to remain properly on the processing table. Alternatively, it may suddenly loosen and fall off after rising to a certain height, posing a safety hazard. This not only forces operators to frequently stop the machine for cleaning, severely reducing processing efficiency, but may also cause abnormal interference between the stamping head and the workpiece, damaging the mold or the workpiece. Summary of the Invention

[0004] To improve processing efficiency, this application provides a tool for cutting and shaping iron teeth.

[0005] The iron tooth trimming and shaping equipment provided in this application adopts the following technical solution: A toothed edge trimming and shaping device includes a slide, a punch head, a first spring, and a stripper rod. The punch head is fixedly connected to the lower end of the slide, and the stripper rod is slidably connected to the outer wall of the slide. One end of the first spring is fixedly connected to the lower end of the slide, and the other end of the first spring is fixedly connected to one end of the stripper rod. The other end of the stripper rod is used to abut against the workpiece.

[0006] By adopting the above technical solution, when the slide moves the punch head downwards, the unloading rod abuts against the workpiece before the punch head and presses it tightly, and the first spring is compressed and stores energy; as the slide continues to move downwards, the punch head completes the punching and separation; when the slide returns upwards, the first spring releases its stored energy and pushes the unloading rod downwards relative to the slide, pushing away any scrap material that may be stuck to the outer ring of the punch head, thus achieving automatic unloading. The unloading rod is slidably connected to the outer wall of the slide, and the first spring is directly connected between the lower end of the slide and the unloading rod, eliminating the need for an external frame or additional support components, simplifying the overall structure of the equipment and reducing manufacturing costs.

[0007] Preferably, the assembly includes a frame, a support base, a pressure plate, and a second spring. The frame is fixedly connected to the upper end of the support base, and the slide is slidably connected to the frame. The sliding direction of the slide is vertical. The pressure plate has a clearance opening for the punch head and the unloading rod to pass through. One end of the second spring is detachably connected to the pressure plate, and the other end of the second spring is detachably connected to the frame. Multiple second springs are provided, and the multiple second springs are arranged circumferentially along the edge of the pressure plate. The upper end surface of the pressure plate is used for the slide to abut against, and the lower end surface of the pressure plate is used to abut against the workpiece.

[0008] By adopting the above technical solution, the slide moves downward, driving the pressure plate downward. The second spring is stretched and stores energy. Since the height of the scrap part of the workpiece is higher than that of the punching part, the pressure plate first abuts against the scrap part, while the punch head abuts against the punching part. The slide continues to move downward, and the pressure plate presses the scrap part tightly, causing it to deform. Simultaneously, the punch head completes the punching and separation of the middle part. Utilizing the height difference of the workpiece itself, the parallel operation of pressing the scrap and punching the middle part is achieved. There is no need to wait for the pressure plate to be fully pressed before punching, shortening the time of a single punching cycle and improving processing efficiency. The pressure plate always presses the scrap part tightly during the punching process, effectively preventing the scrap from warping or shifting during punching and ensuring punching accuracy. At the same time, when the workpiece is stuck too tightly to the punch head, causing the unloading rod to be unable to push the workpiece away, as the punch head moves upward, the workpiece is driven to move continuously upward towards the pressure plate. The second spring is compressed, applying force to the pressure plate and assisting the scrap to detach from the punch head.

[0009] Preferably, the outer wall of the stamping head is provided with a groove, the length direction of the groove is vertical, the unloading rod is slidably connected to the groove wall, and the sliding direction of the unloading rod is vertical.

[0010] By adopting the above technical solution, the movement trajectory of the unloading rod is constrained to a vertical direction parallel to the stamping head, ensuring that the unloading rod always maintains accurate linear movement when it comes into contact with the workpiece and pushes away the scrap. The sliding fit structure between the slide and the unloading rod is compact, eliminating the need to add an independent guide bracket outside the stamping head, reducing the space occupied around the stamping head, and facilitating the miniaturization design of the mold.

[0011] Preferably, the inner wall of the clearance opening is provided with a limiting groove, and the unloading rod is slidably embedded in the limiting groove.

[0012] By adopting the above technical solution, the synergistic effect of the limiting groove and the slide groove precisely constrains the relative motion trajectory between the unloading rod, the punching head, and the pressure plate. This ensures the timing and positional accuracy of the three actions during the downward movement: the pressure plate pressing the waste, the punching head cutting the middle part, and the unloading rod pushing away the waste. It avoids interference and jamming with the punching head or pressure plate due to the offset of the unloading rod, further improving the reliability of the unloading action and the stability of the equipment operation.

[0013] Preferably, the frame includes a gantry and guide blocks. The gantry is fixedly connected to the upper end of the support base. The gantry and the support base together form a receiving opening. The guide blocks are fixedly connected to the inner wall of the receiving opening. There are four guide blocks, all of which are located on the outer periphery of the slide. The slide is slidably connected to the outer wall of the guide blocks.

[0014] By adopting the above technical solution, the guiding accuracy and anti-eccentric load capacity of the slide block during vertical reciprocating motion are improved, and the lateral offset or torsion that may occur due to uneven force during the stamping process is effectively suppressed, thereby ensuring the precise alignment between the stamping head fixed at the lower end of the slide block and the workpiece and pressure plate clearance below.

[0015] Preferably, the guide block is fixedly connected to a connecting column away from the outer wall of the slide, the outer wall of the pressure plate is provided with a connecting port, and both ends of the second spring are provided with hooks, with the two hooks respectively hung on the connecting port and the connecting column.

[0016] By adopting the above technical solution, the installation and removal of the second spring can be completed quickly without the need for additional tools. This greatly facilitates operators in replacing second springs of different specifications or stiffnesses based on the height difference, stiffness, and deformation characteristics of the workpiece scrap, thus improving the adjustment efficiency and adaptability of the equipment. The connecting column is fixed to the outer wall of the guide block, and the connecting port is located on the outer wall of the pressure plate. This allows the second spring to be positioned on the outer periphery of the pressure plate, avoiding the punching area directly below the punch head and the movement area of ​​the unloading rod. This ensures that the second spring is not disturbed by punching scrap and moving parts during extension and retraction, and also facilitates operators in observing the working status of the second spring and performing maintenance and replacement. The hook-and-connection structure of the hook, connecting port, and connecting column is simple and reliable. Replacing the second spring does not require disassembling other parts, further enhancing the ease of equipment maintenance.

[0017] Preferably, there are multiple connecting columns, and the multiple connecting columns are evenly spaced along the height direction.

[0018] By adopting the above technical solution, operators can hang the hook of the second spring on connecting columns at different heights according to the height difference, stiffness, and deformation characteristics of the scrap portion of the workpiece. This changes the initial tensile length and preload of the second spring, allowing for graded adjustment of the clamping force of the pressure plate on the scrap portion. Simultaneously, because the tilt angle of the second spring changes with the hanging height, the magnitude of the horizontal component force generated by the pressure plate during the clamping process is also adjustable, enabling the equipment to adapt to the processing needs of workpieces with different thicknesses, materials, and deformation characteristics. This graded adjustment structure allows for rapid adjustment of clamping performance without replacing the second spring, reducing debugging time and operating costs. Furthermore, the evenly spaced connecting columns along the height direction ensure the regularity and repeatability of the adjustment, facilitating accurate selection and recording by operators, further expanding the processing range of the equipment.

[0019] Preferably, it further includes a fixing block and a limiting post. The fixing block is fixedly connected to the outer wall of the guide block and is located on the outer periphery of the slide. The limiting post is detachably connected to the fixing block, and the lower end of the limiting post is used to abut against the upper end surface of the pressure plate.

[0020] By adopting the above technical solution, when the slide moves upward during the return stroke and the pressure plate rises due to the adhesion of the waste material, the forces of the first and second springs are insufficient to dislodge the waste material. The upper end of the pressure plate abuts against the lower end of the limiting post, preventing the pressure plate from continuing to rise. The punch head continues to move upward, and the limiting post applies force to the pressure plate, causing the waste material to fall. This ensures that the pressure plate remains in an appropriate position after completing the actions of pressing the waste material and assisting in unloading. It avoids the pressure plate rising excessively, causing the waste material to fall and bounce up and down significantly. When the pressure plate bounces downward, it is easy to dislodge from the punch head or even difficult to reset. The pressure plate getting stuck under the punch head affects subsequent punching and can easily lead to equipment damage.

[0021] Preferably, the fixing block is provided with an adjustment port, the adjustment port extends vertically through the fixing block, and the limiting post is threadedly connected to the inner wall of the adjustment port.

[0022] By adopting the above technical solution, operators can precisely change the contact position between the lower end of the limiting post and the upper surface of the pressure plate simply by rotating the limiting post. This allows for continuous and precise control of the pressure plate's upward stroke, eliminating the need to replace limiting posts of different lengths and greatly improving the convenience and efficiency of adjustment. Simultaneously, the threaded connection has excellent self-locking performance, reliably maintaining the adjusted height position during operation and preventing the limiting post from loosening due to vibration or impact, which could affect the pressure plate's stroke accuracy. Furthermore, the vertically penetrating design of the adjustment port through the fixed block ensures that the limiting post has a sufficient adjustment range while also facilitating observation and operation by operators from above or below the fixed block, further enhancing the equipment's maintainability and operational flexibility.

[0023] Preferably, the fixing block is provided with an adjustment port, the adjustment port extends vertically through the fixing block, and the limiting post is threadedly connected to the inner wall of the adjustment port.

[0024] By adopting the above technical solution, operators can precisely change the contact position between the lower end of the limiting post and the upper surface of the pressure plate simply by rotating the limiting post, thereby enabling continuous and precise control of the pressure plate's upward stroke. This eliminates the need to replace limiting posts of different lengths, greatly improving the convenience and efficiency of adjustment. Simultaneously, the threaded connection has excellent self-locking performance, reliably maintaining the adjusted height position during operation and preventing the limiting post from loosening due to vibration or impact, which could affect the pressure plate's stroke accuracy. Furthermore, the vertically penetrating design of the adjustment port through the fixed block ensures that the limiting post has a sufficient adjustment range while also facilitating observation and operation by the operator from above or below the fixed block, further enhancing the equipment's maintainability and operational flexibility. This stepless adjustment structure complements the aforementioned multi-stage connecting post's graded adjustment, achieving graded adjustment of the pressure plate's clamping force and continuous, precise adjustment of the pressure plate's stroke, jointly improving the equipment's adaptability to different workpieces.

[0025] Preferably, it also includes an air pump and a hose. The lower end face of the pressure plate is provided with an air blowing groove, the outer wall of the pressure plate is provided with an air inlet, the pressure plate is provided with an air intake channel, the air intake channel is connected to the air inlet and the air blowing groove, the pump body of the air pump is fixedly connected to the frame, one end of the hose is coaxially fixedly connected to the inner wall of the air outlet of the air pump, and the other end of the hose is coaxially fixedly connected to the inner wall of the air inlet.

[0026] By adopting the above technical solution, compressed gas is ejected from the air blowing groove, forming an air cushion or airflow auxiliary thrust between the workpiece scrap and the pressure plate. The airflow impact further pushes the adhered scrap away from the stamping head, significantly improving the reliability and thoroughness of unloading. This is particularly suitable for processing thin metal sheets with oil films on the surface or those prone to vacuum adsorption after stamping. The two ends of the hose are coaxially fixed to the air pump outlet and the inner wall of the pressure plate inlet, ensuring the air circuit's sealing and connection stability. The hose's flexibility allows the pressure plate to maintain unobstructed airflow during its up-and-down movement, without affecting its normal extension and retraction stroke. The air blowing groove is located on the lower end face of the pressure plate, allowing the airflow to directly act on the contact area between the scrap and the pressure plate. This results in a short airflow path, low pressure loss, and improved air-assisted efficiency. Simultaneously, it facilitates the cleaning of scrap generated during the stamping process.

[0027] In summary, this application includes at least one of the following beneficial technical effects: When the slide moves the punch head downwards, the unloading rod abuts against the workpiece before the punch head and presses it firmly, compressing and storing energy in the first spring. As the slide continues to descend, the punch head completes the punching and separation. When the slide returns upwards, the first spring releases its stored energy and pushes the unloading rod downwards relative to the slide, pushing away any scrap material that may be stuck to the outer ring of the punch head, thus achieving automatic unloading. The unloading rod is slidably connected to the outer wall of the slide, and the first spring is directly connected between the lower end of the slide and the unloading rod, eliminating the need for an external frame or additional support components, simplifying the overall structure of the equipment and reducing manufacturing costs. The slide moves downwards, causing the pressure plate to descend. The second spring is stretched and stores energy. Since the height of the scrap portion of the workpiece is higher than the punching portion, the pressure plate first abuts against the scrap portion, while the punch head abuts against the punching portion. The slide continues to descend, and the pressure plate presses the scrap portion tightly, causing it to deform. Simultaneously, the punch head completes the punching and separation of the middle portion. Utilizing the height difference of the workpiece itself, parallel operations of pressing the scrap and punching the middle portion are achieved, eliminating the need to wait for the pressure plate to fully press before punching. This shortens the time of a single punching cycle and improves processing efficiency. The pressure plate keeps the scrap portion pressed tightly during the punching process, effectively preventing the scrap from warping or shifting during punching and ensuring punching accuracy. Simultaneously, when the workpiece is too tightly adhered to the punch head, preventing the unloading rod from pushing the workpiece away, as the punch head moves upwards, the workpiece is driven upwards towards the pressure plate. The second spring is compressed, applying force to the pressure plate and assisting the scrap to detach from the punch head. When the slide returns upward and the pressure plate rises due to the adhesion of the scrap, the forces of the first and second springs are insufficient to dislodge the scrap. The upper end of the pressure plate abuts against the lower end of the limit post, preventing the pressure plate from continuing to rise. The punch head continues to move upward, and the limit post applies force to the pressure plate, causing the scrap to fall. This ensures that the pressure plate remains in an appropriate position after completing the actions of pressing the scrap and assisting in unloading. It avoids the pressure plate rising excessively, causing the scrap to bounce up and down significantly after falling. When the pressure plate bounces downward, it is easy to detach from the punch head or even be difficult to reset. If the pressure plate gets stuck under the punch head, it will affect subsequent punching and may easily damage the equipment. Attached Figure Description

[0040] The implementation principle of the iron tooth trimming and shaping equipment in this application embodiment is as follows: The operator hangs the hooks at both ends of the second spring 52 on the connecting column 121 at the corresponding height according to the characteristics of the workpiece, and rotates the limiting column 62 to adjust the upward stroke of the pressure plate 51; after starting the iron tooth trimming and shaping, the hydraulic cylinder 31 drives the slide 32 to slide vertically downward along the outer wall of the four guide blocks 12. The lower end face of the slide 32 abuts against the upper end face of the pressure plate 51 and pushes the pressure plate 51 downward synchronously. The second spring 52 is stretched, the lower end face of the pressure plate 51 abuts against the scrap part of the workpiece, and at the same time, the punch head 33 abuts against the punching part of the workpiece, the unloading rod 42 abuts against the scrap part of the workpiece, the first spring 41 contracts, the slide 32 continues to descend, the pressure plate 51 presses the scrap part to deform it, the punch head 33 completes the punching and separation, and the middle part passes through the discharge port 8. 2. The material falls into drawer 91; after punching, the slide 32 returns upward, and the pressure plate 51 rises synchronously. The first spring 41 and compressed gas exert force on the waste material, causing the waste material to separate from the punch head 33 and the pressure plate 51. When the first spring 41 can no longer separate the waste material from the punch head 33, the punch head 33 continues to rise. At this time, the second spring 52 begins to contract, and the second spring 52 exerts further force on the waste material, causing the waste material to separate from the punch head 33. If the waste material still cannot be separated from the punch head 33, when the upper end of the pressure plate 51 abuts against the lower end of the limiting post 62, the slide 32 and the punch head 33 continue to rise, pushing the waste material away from the punch head 33. The middle part after punching slides along the guide groove 911 to the unloading port 912 and falls into the receiving box 93. Fine debris is separated through the filter port 913 and falls into the debris box 92, completing the classification and collection.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
