Description

Technical Field

[0001] This invention belongs to the field of surface treatment technology, and more specifically, relates to a deburring device. Background Technology

[0002] As a widely used functional component in the furniture industry, handles are usually manufactured using casting. After the casting process is completed, in order to ensure the aesthetics and safety of the product, the outer edges must be carefully deburred.

[0003] However, handles are often designed in various shapes and are irregular in form, and their surface finish and integrity are subject to high quality requirements. If conventional deburring processes such as sandblasting or grinding are used in this stage, it may be difficult to completely remove all burrs due to their complex shapes. In addition, it is easy to cause unnecessary scratches, dents and other damage to the surface of the handle during the operation, thereby affecting the appearance quality of the product. Summary of the Invention

[0004] The main objective of this invention is to provide a deburring device that removes burrs from the outer edge of handles by stamping, thereby reducing damage to the handle surface.

[0005] According to a first aspect of the present invention, a deburring device is provided, comprising a frame, a platform and a stamping device on the frame, a mold on the platform, and a cavity adapted to a handle, the cavity extending vertically.

[0006] The stamping device includes a stamping head and a drive module. The drive module is used to drive the stamping head to rise and fall. The stamping head is located above the mold. A punch is provided on the side of the stamping head facing the mold. The punch is used to press down the handle so that the handle passes through the cavity to remove burrs.

[0007] In the aforementioned deburring equipment, a dust collection box is provided on the side of the platform facing away from the punch head. The dust collection box is slidably engaged with the platform, and the sliding direction of the dust collection box is a first direction. The dust collection box is connected to an external negative pressure device.

[0008] The platform is equipped with a traction mechanism and a winding mechanism. One end of the dust collection box along the first direction is connected to the stamping head through the traction structure, and the other end of the dust collection box along the first direction is connected to the winding mechanism.

[0009] When the stamping head rises, the traction mechanism drives the dust collection box to slide so that the dust collection box covers the lower end of the cavity;

[0010] As the stamping head descends, the winding mechanism causes the dust collection box to slide, allowing the dust collection box to move away from the lower end of the cavity.

[0011] In the above-mentioned deburring equipment, the traction mechanism includes a first fixed pulley, a second fixed pulley and a first traction rope. The first fixed pulley is disposed on the side of the platform away from the punch head, the second fixed pulley is disposed on the side of the platform facing the punch head, and the platform is provided with a wire passage hole.

[0012] One end of the first traction rope is fixedly connected to the dust collection box, and the other end of the first traction rope is fixedly connected to the punch head. The first traction rope passes around the first fixed pulley and the second fixed pulley and is threaded through the wire hole.

[0013] In the deburring device described above, a third fixed pulley is provided in the wire hole, the first traction rope passes around the third fixed pulley, and the second fixed pulley is located between the mold and the third fixed pulley.

[0014] In the deburring equipment described above, the winding mechanism includes a rotating shaft, an accumulator, and a second traction rope. The rotating shaft is rotatably disposed on the side of the platform opposite to the punch head. The accumulator is connected to the rotating shaft. One end of the second traction rope is fixedly connected to the dust collection box, and the other end of the second traction rope is fixedly connected to the rotating shaft. The axis of the rotating shaft is perpendicular to the moving direction of the dust collection box.

[0015] When the stamping head rises, the second traction rope is pulled out from the rotating shaft, and the accumulator stores energy;

[0016] As the stamping head descends, the accumulator drives the rotating shaft to wind up the second traction rope, causing the dust collection box to move in a direction close to the rotating shaft.

[0017] In the deburring device described above, the accumulator includes a housing and a planar spiral spring. The housing is fixedly connected to the platform, and the planar spiral spring is disposed in the housing. The outer end of the planar spiral spring is fixedly connected to the housing, and the inner end of the planar spiral spring is fixedly connected to the rotating shaft.

[0018] In the above-mentioned deburring equipment, the platform is provided with a limiting strip on the side facing away from the punch head. There are two limiting strips arranged at intervals. A support part protrudes from the limiting strip in the direction close to the other limiting strip, and a groove is formed between the support part and the platform.

[0019] The dustbin includes a box body, the top of which is bent outward to form an edge that engages with a slot, allowing the dustbin to slide along the slot.

[0020] In the deburring device described above, the box body includes a box bottom, the edge of which extends upward to form a box wall, and the top of the box wall bends outward to form the edge.

[0021] In the deburring equipment described above, the stroke of the stamping head is H, the length of the mold in the first direction is L, the depth of the cavity is d, and H>L+2d.

[0022] In the deburring equipment described above, the side of the platform facing away from the stamping head is flush with the side of the mold facing away from the stamping head.

[0023] One of the above-described technical solutions of the present invention has at least one of the following advantages or beneficial effects:

[0024] In this invention, a stamping method is used to remove burrs. Before processing, the handle has burrs and can be placed above the cavity. Then, the stamping head descends and the punch presses on the handle, pushing the handle through the cavity. Since the shape of the handle matches the shape of the cavity, the burrs are scraped off by the edge of the cavity, thereby achieving deburring and reducing damage to the surface of the handle.

[0025] After deburring, some burrs adhere to the inner wall of the cavity due to static electricity. This can easily damage the surface when the next handle passes through the cavity, and repeated pressing can also affect the precision of the cavity wall. Therefore, a dust collection box is installed. When the punch head rises, the dust collection box moves to the lower end of the cavity, covering it. Under the action of an external negative pressure device, the dust collection box creates negative pressure to suck up the burrs in the cavity, preventing them from adhering to the inner wall. When the punch head descends, the winding mechanism moves the dust collection box away from the lower end of the cavity, exposing the lower end of the cavity and ensuring that the handle can pass through the cavity normally to complete the deburring. This linkage method further avoids damage to the handle surface.

[0026] Furthermore, the winding mechanism uses an accumulator. When the punch head rises, it pulls the second traction rope, which is pulled out from the rotating shaft. During this process, the rotating shaft rotates to store energy in the accumulator. When the punch head descends, the accumulator drives the rotating shaft to reverse, thereby winding up the second traction rope. This allows the dust collection box to leave the lower end of the cavity autonomously without the need for additional power, making the entire structure simpler. Attached Figure Description

[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] Reference Figures 1 to 5 As shown, a deburring device includes a frame 1, a platform 2 and a stamping device 3 on the frame 1, a mold 4 on the platform 2, and a cavity 41 adapted to the handle on the mold 4, with the cavity 41 extending through the top and bottom.

[0037] The stamping device 3 includes a stamping head 31 and a drive module 32. The drive module 32 is used to drive the stamping head 31 to rise and fall. The stamping head 31 is located above the mold 4. A punch 33 is provided on the side of the stamping head 31 facing the mold 4. The punch 33 is used to press down the handle so that the handle passes through the cavity 41 to remove burrs.

[0038] The burrs are removed by stamping. Before processing, the handle has burrs and can be placed above the cavity 41. Then, the stamping head 31 descends, and the punch 33 presses onto the handle, pushing it through the cavity 41. Because the shape of the handle matches the shape of the cavity 41, the burrs are scraped off by the edge of the cavity 41, thus achieving deburring and reducing damage to the handle surface.

[0039] In this application, with the handle lying down as the reference, the cavity 41 is adapted to the shape of the handle lying down. Based on the design of the mold 4, the burrs of the handle are generally located on its outer periphery and protrude in the horizontal direction. Therefore, the handle can be placed on top of the cavity 41 in a lying down posture. Due to the burrs, the handle will not directly enter the cavity 41; only under the stamping of the punch 33 will the handle pass through the cavity 41 to remove the burrs.

[0040] After the burrs are scraped off, some burrs will adhere to the inner wall of the cavity 41 under the action of static electricity. When the next handle passes through the cavity 41, it is easy to damage the surface. In addition, repeated squeezing can also affect the precision of the inner wall of the cavity 41. Therefore, a dust collection box 5 is provided on the side of the platform 2 facing away from the punch head 31. The dust collection box 5 is slidably engaged with the platform 2. The sliding direction of the dust collection box 5 is the first direction. The dust collection box 5 is connected to an external negative pressure device.

[0041] Platform 2 is equipped with a traction mechanism 6 and a winding mechanism 7. One end of the dust collection box 5 along the first direction is connected to the punch head 31 through the traction structure, and the other end of the dust collection box 5 along the first direction is connected to the winding mechanism 7.

[0042] When the punch head 31 rises, the traction mechanism 6 drives the dust collection box 5 to slide. The punch head 31 rises to the upper limit position, and the dust collection box 5 just covers the lower end of the cavity 41. Under the action of the external negative pressure device, the dust collection box 5 will form a negative pressure to suck up the burrs in the cavity 41, so as to prevent the burrs from adhering to the inner wall of the cavity 41.

[0043] When the stamping head 31 descends, the winding mechanism 7 drives the dust collection box 5 to slide, gradually moving away from the lower end of the cavity 41, so that the lower end of the cavity 41 is exposed, ensuring that the handle can pass through the cavity 41 normally and complete the deburring.

[0044] The coordinated operation of the stamping head 31, the traction mechanism 6, and the winding mechanism 7 further prevents damage to the handle surface.

[0045] Specifically, the traction mechanism 6 includes a first fixed pulley 61, a second fixed pulley 62 and a first traction rope 63. The first fixed pulley 61 is located on the side of the platform 2 away from the punch head 31, and the second fixed pulley 62 is located on the side of the platform 2 facing the punch head 31. The platform 2 is provided with a wire passage hole.

[0046] One end of the first traction rope 63 is fixedly connected to the dust collection box 5, and the other end of the first traction rope 63 is fixedly connected to the punch head 31. The first traction rope 63 starts from the dust collection box 5, first passes around the first fixed pulley 61, then passes through the wire hole, then passes around the second fixed pulley 62, and finally connects to the punch head 31. In this way, when the punch head 31 rises, it will pull the first traction rope 63, thereby pulling the dust collection box 5 to move. When the punch head 31 descends, the first traction rope 63 will loosen, allowing the winding mechanism 7 to drive the dust collection box 5 to move.

[0047] In this embodiment, a third fixed pulley 64 is provided in the wire hole, the first traction rope 63 passes around the third fixed pulley 64, and the second fixed pulley 62 is located between the mold 4 and the third fixed pulley 64. The first fixed pulley 61, the second fixed pulley 62 and the second fixed pulley 62 cooperate to support the movement of the first traction rope 63.

[0048] Preferably, fasteners can be provided on the first fixed pulley 61, the second fixed pulley 62 and the third fixed pulley 64 to prevent the first traction rope 63 from coming off.

[0049] In this embodiment, the winding mechanism 7 includes a rotating shaft, an accumulator 71, and a second traction rope 72. The rotating shaft is rotatably disposed on the side of the platform 2 facing away from the punch head 31. The accumulator 71 is connected to the rotating shaft. One end of the second traction rope 72 is fixedly connected to the dust collection box 5, and the other end of the second traction rope 72 is fixedly connected to the rotating shaft. The axis of the rotating shaft is perpendicular to the moving direction of the dust collection box 5.

[0050] When the stamping head 31 rises, the pulling force of the stamping head 31 pulling the first traction rope 63 is greater than the pulling force of the accumulator 71. The dust collection box 5 gradually approaches the lower end of the cavity 41. At this time, the dust collection box 5 will pull the second traction rope 72 to move, pulling the second traction rope 72 cable out from the rotating shaft. At this time, the accumulator 71 stores energy.

[0051] When the punch head 31 descends, the punch head 31 no longer provides tension, and the first traction rope 63 will slacken. At this time, the accumulator 71 has a greater tension, and the accumulator 71 will drive the rotating shaft to wind up the second traction rope 72 so that the dust collection box 5 moves in the direction close to the rotating shaft and leaves the lower end of the cavity 41.

[0052] In this structure, when the stamping head 31 rises, it can automatically drive the dust collection box 5 to cover the lower end of the cavity 41 for dust collection. When the stamping head 31 falls, the dust collection box 5 can automatically leave the lower end of the cavity 41, allowing the handle to continue to be deburred. This is convenient, quick, and does not require additional power, and the cost is relatively low.

[0053] In this embodiment, the mold 4 is provided with a relief groove 42 on the side near the stamping head 31. The relief groove 42 extends along a second direction, which is horizontal and perpendicular to the first direction. Both ends of the relief groove 42 in the second direction are open ends.

[0054] In practice, the worker will be positioned at one end of the mold 4 along the second direction, use a tool to pick up the handle, and place the handle on the mold. The clearance groove 42 is used to avoid the tool. In this way, after the handle is placed with the tool, the tool can be pulled out from the clearance groove 42, making the placement of the handle more stable.

[0055] In this embodiment, the accumulator 71 includes a housing and a planar spiral spring. The housing is fixedly connected to the platform 2, and the planar spiral spring is disposed in the housing. The outer end of the planar spiral spring is fixedly connected to the housing, and the inner end of the planar spiral spring is fixedly connected to the rotating shaft.

[0056] When the second traction rope 72 is pulled out, it will drive the shaft to rotate. At this time, the shaft will twist the planar spiral spring, and the planar spiral spring will store energy. When the first traction rope 63 loses power, the planar spiral spring will return to its original state, thereby driving the shaft to reverse and rewind the second traction rope 72.

[0057] In this embodiment, a limiting strip 21 is provided on the side of the platform 2 facing away from the stamping head 31. There are two limiting strips 21 arranged at intervals. A support part 22 protrudes from the limiting strip 21 in the direction close to the other limiting strip 21, and a groove 23 is formed between the support part 22 and the platform 2.

[0058] The dust collection box 5 includes a box body, which includes a box bottom 51. The edge of the box bottom 51 extends upward to form a box wall 52, and the top of the box wall 52 bends outward to form an edge 53. The box bottom 51 can be set in a cone shape to facilitate the collection of burrs. The box bottom 51 is provided with a through hole, which is connected to an external negative pressure device through a pipe.

[0059] The edge 53 is inserted into the slot 23, which allows the dustbin 5 to be suspended on the limiting strip 21, and the dustbin 5 can slide along the slot 23. The limiting strip 21 limits the direction of movement of the dustbin 5.

[0060] In practice, there are four box walls 52 that form a rectangle. Therefore, the edge 53 forms a rectangular ring. When the edge 53 is inserted into the slot 23, the box cannot rotate and can only move along the extension direction of the slot 23.

[0061] Preferably, the side of the platform 2 facing away from the stamping head 31 is flush with the side of the mold 4 facing away from the stamping head 31. In this way, the edge 53 is close to the side of the mold 4 facing away from the stamping head 31, and the internal cavity of the box can be better connected with the cavity 41, resulting in better suction.

[0062] In this embodiment, the stroke of the stamping head 31 is H, the length of the mold 4 in the first direction is L, the depth of the cavity 41 is d, and H>L+2d;

[0063] The height of the handle after it is laid flat is less than the depth of the cavity 41. Therefore, during the process of the stamping head 31 descending, before the punch 33 touches the handle, the dust collection box 5 will completely leave the lower end of the cavity 41, ensuring that the handle can pass through the cavity 41 normally.

[0064] In this embodiment, the drive module 32 is a hydraulic cylinder.

[0065] In some other embodiments, the drive module 32 may be a cylinder, a lead screw mechanism driven by a servo motor, or a crank-connecting rod mechanism driven by a motor.

[0066] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
