Description

Technical Field

[0001] This utility model relates to the field of work technology, and in particular to a cutting tool and an air conditioner assembly line. Background Technology

[0002] In the injection molding process of decorative strips for cabinet air conditioners, a two-part synchronous injection molding method is typically used to produce I-shaped structural parts. This injection molding process involves setting hot melt adhesive channels within the injection mold, resulting in multiple gate residue structures (i.e., sprue gates) distributed along the central axis of the molded workpiece. These sprue gates, as material flow channel residues from the injection molding process, must be completely removed in post-processing steps to obtain the final product – the decorative strip. However, existing sprue gate removal technologies have the following shortcomings:

[0003] First, the operation is inefficient. Because of the sequential cutting method, each sprue requires two shearing operations (a total of 2n shearing actions, where n is the number of sprues), resulting in significant time consumption. Second, there are prominent safety hazards. Due to the inherent elasticity of the injection molding material, coupled with the tensile stress on the sprue in the middle of the workpiece, unpredictable ejection motion can easily occur during shearing, posing a safety threat to operators or surrounding personnel. This ejection phenomenon can create cumulative risks in continuous operation environments, and the splashing material may cause secondary injuries. Utility Model Content

[0050] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0051] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0052] In the injection molding process of decorative strips for cabinet air conditioners, a two-part synchronous injection molding method is typically used to produce I-shaped structural parts. This injection molding process involves setting hot melt adhesive channels within the injection mold, resulting in multiple gate residue structures (i.e., sprue gates) distributed along the central axis of the molded workpiece. These sprue gates, as material flow channel residues from the injection molding process, must be completely removed in post-processing steps to obtain the final product – the decorative strip. However, existing sprue gate removal technologies have the following shortcomings:

[0053] First, the operation is inefficient. Because of the sequential cutting method, each sprue requires two shearing operations (a total of 2n shearing actions, where n is the number of sprues), resulting in significant time consumption. Second, there are prominent safety hazards. Due to the inherent elasticity of the injection molding material, coupled with the tensile stress on the sprue in the middle of the workpiece, unpredictable ejection motion can easily occur during shearing, posing a safety threat to operators or surrounding personnel. This ejection phenomenon can create cumulative risks in continuous operation environments, and the splashing material may cause secondary injuries.

[0054] Therefore, to solve the above problems, such as Figures 1-2 As shown, this utility model proposes a shearing fixture that improves operational efficiency and reduces safety hazards, comprising:

[0055] Base 10;

[0056] Tensioning device 20, which is located on the base 10, is used to fix workpiece 50;

[0057] An anti-bounce device 30 is located in the middle of the tensioning device 20; the anti-bounce device 30 is configured to correspond one-to-one with each sprue 501 of the workpiece 50.

[0058] A shearing device 40 is provided for each anti-bounce device 30, and the shearing device 40 is used to cut off the water inlet 501.

[0059] It is understood that the shearing fixture proposed in this embodiment also includes a control device 60, which is used to control the shearing fixture to shear each sprue 501 of the workpiece 50; and the control device 60 is composed of a button box and an electrical box, and is controlled by a PLC.

[0060] like Figure 3 As shown, the workpiece 50 proposed in this embodiment is preferably produced by a two-piece synchronous injection molding method to form an I-shaped structural part, and the formed workpiece 50 has four sprue 501 distributed along its central axis.

[0061] When the operator places the workpiece 50 on the tensioning device 20, and needs to position each sprue 501 of the workpiece 50 below the anti-bounce device 30, the control device 60 is activated. The control device 60 first activates the tensioning device 20, causing the tensioning device 20 to move accordingly to fix the workpiece 50 in a preset position, which is equivalent to the sprue 501 being directly below the anti-bounce device 30. The control device 60 then activates the shearing device 40, causing the shearing device 40 to move accordingly, so that both sides of the same sprue 501 are within the shearing range of the shearing device 40. Then, all sprue 501s of the same workpiece 50 are simultaneously sheared to obtain the final product - the decorative strip.

[0062] Therefore, by cooperating with the tensioning device 20 and the shearing device 40, this utility model enables the shearing device 40 to simultaneously cut off all the sprues 501 of the same workpiece 50, thereby improving operating efficiency and continuous operation stability; and the cut sprues 501 will be blocked by the anti-bounce device 30 after shearing, suppressing unpredictable ejection motion generated at the moment of shearing, preventing secondary injury, ensuring the safety of operators or surrounding personnel, and reducing safety risks.

[0063] The first direction proposed in this utility model is the X-axis direction or the length direction of the base 10; the second direction proposed in this utility model is the Y-axis direction or the width direction of the base 10, and so on.

[0064] In some embodiments, such as Figure 1 and Figure 6 As shown, the top edge of the base 10 is provided with an aluminum profile frame, which is connected by T-bolts to form a stable cuboid structure. The protective plate 70 is embedded in the profile groove to achieve a sealed dustproof effect. The side of the aluminum profile frame facing the control device 60 (equivalent to the loading area) does not have the protective plate 70 to facilitate the operator's handling of the workpiece 50. However, the side without the protective plate 70 is provided with a safety light curtain 80. When a person approaches the working shearing fixture and is detected by the safety light curtain 80, the safety light curtain 80 will send an emergency stop signal to the control device 60, so that the control device 60 can control the entire shearing fixture to stop operating. Thus, the safety light curtain 80 and the control device 60 form a "detection-blocking" closed-loop protection to avoid safety accidents.

[0065] In some embodiments, to ensure that the shearing device 40 can simultaneously shear the same gate 501 and to ensure the smoothness of the gate cut-off area, it is not necessary to repeatedly trim the gate cut-off area, such as... Figure 2As shown, the shearing device 40 includes a first shearing component 41 and a second shearing component 42; the first shearing component 41 and the second shearing component 42 are respectively disposed on both sides of each of the water inlets 501 along the second direction, and cooperate to shear the same water inlet 501.

[0066] It should be noted that each sprue 501 of the workpiece 50 is provided with a first cutting component 41 and a second cutting component 42 on both sides respectively. All the first cutting components 41 first cut off one side of the sprue 501 together, and at the same time, all the second cutting components 42 then cut off the other side of the sprue 501 together, thereby completing the removal of all sprue 501 of the workpiece 50; or all the second cutting components 42 first cut off one side of the sprue 501 together, and at the same time, all the first cutting components 41 then cut off the other side of the sprue 501 together, which is not limited here.

[0067] Thus, when the tensioning device 20 moves accordingly to fix the workpiece 50 to the preset position, it is equivalent to the sprue 501 being located directly below the anti-bounce device 30; the control device 60 then activates the first cutting component 41 and the second cutting component 42 to move accordingly, so that both sides of the same sprue 501 are respectively within the cutting range of the first cutting component 41 and the second cutting component 42, and then all sprues 501 of the same workpiece 50 are cut off at the same time, thereby obtaining the final product - decorative strip.

[0068] In some embodiments, such as Figure 1 As shown, the tensioning device 20 includes:

[0069] A sliding seat 201 and a fixed seat 202 extend along a first direction of the base 10, and the sliding seat 201 and the fixed seat 202 are spaced apart along a second direction;

[0070] At least one fifth drive component 203, the output end of which is connected to the sliding seat 201; the fifth drive component 203 is used to drive the sliding seat 201 to move along the second direction, forming an adjustable clamping space (not shown, same throughout) with the fixed seat 202, the clamping space being used to place the workpiece 50.

[0071] It should be noted that the fifth drive assembly 203 proposed in this embodiment is preferably a cylinder assembly; and when there are multiple fifth drive assemblies 203, the multiple fifth drive assemblies 203 are arranged side by side along the first direction. The shape of the clamping space is preferably rectangular.

[0072] Furthermore, the workpiece 50 proposed in this embodiment has various sizes and models. Different models of workpiece 50 correspond to different PLC control programs. The control device 60 has PLC control programs pre-inputted for different models of workpiece 50. When a certain model of workpiece 50 needs to have its sprue 501 cut off, the operator needs to select the corresponding PLC control program for the workpiece 50 so that the cutting tool can be used for subsequent steps, thereby improving work efficiency.

[0073] Initially, the tensioning device 20 is set such that the sliding seat 201 is far from the fixed seat 202, and the distance between them is greater than the width of the workpiece 50. When it is necessary to remove the sprue 501 of the workpiece 50, the workpiece 50 is first placed in the clamping space between the sliding seat 201 and the fixed seat 202. Then, the control device 60 activates all the fifth drive components 203. The fifth drive components 203 together drive the sliding seat 201 to move towards the fixed seat 202, thereby reducing the length of the clamping space along the second direction. This restricts the movement of the workpiece 50 in the second direction, eliminates the displacement deviation of the workpiece 50 in the second direction, ensures the relative positional accuracy of the first shearing component 41 and the second shearing component 42 with the sprue 501 of the workpiece 50, improves the stability of the shearing fixture, improves the smoothness of the sprue removal, and avoids dimensional deviations or shape distortions caused by offset, which could lead to burrs or incomplete shearing at the sprue removal point.

[0074] Specifically, to further eliminate the displacement deviation of the workpiece 50 in the second direction, ensure the relative positional accuracy of the first shearing assembly 41 and the second shearing assembly 42 with the sprue 501 of the workpiece 50, and improve the smoothness of the sprue removal, such as... Figure 1 As shown, the top of the fixed seat 202 is provided with a plurality of first limiting blocks 204 spaced apart along the first direction. The first limiting blocks 204 cooperate with the sliding seat 201 to limit the displacement of the workpiece 50 along the second direction.

[0075] In some embodiments, to eliminate the displacement deviation of the workpiece 50 in the first direction, further ensure the relative positional accuracy of the first shearing assembly 41 and the second shearing assembly 42 with the sprue 501 of the workpiece 50, and further improve the smoothness of the sprue removal, such as... Figure 1 As shown, the tensioning device 20 also includes a limiting device 21, which is used to limit the displacement of the workpiece 50 along the first direction.

[0076] Specifically, this embodiment proposes a structural composition of the limiting device 21:

[0077] The limiting device 21 includes a second limiting block 211, a pushing block 212, and a sixth driving component 213;

[0078] The base 10 at both ends along the axial direction of the tensioning device 20 is provided with a second limiting block 211 and a pushing block 212, respectively;

[0079] The push block 212 is connected to the output end of the sixth drive component 213;

[0080] The sixth driving component 213 drives the pushing block 212 to move along the first direction, and cooperates with the second limiting block 211 to limit the displacement of the workpiece 50 along the first direction.

[0081] It should be noted that the sixth drive component 213 proposed in this embodiment is preferably a cylinder component.

[0082] Thus, when it is necessary to remove the sprue 501 of workpiece 50, the operator first places workpiece 50 into the clamping space in its initial state. Then, the control device 60 activates all the fifth drive components 203. The fifth drive components 203 together drive the sliding seat 201 to move towards the fixed seat 202, thereby reducing the length of the clamping space along the second direction and thus restricting the movement of workpiece 50 in the second direction. Then, the control device 60 activates the sixth drive component 213. The sixth drive component 213 drives the push block 212 to move towards the second limit block 211, thereby reducing the length of the clamping space along the first direction and thus restricting the movement of workpiece 50 in the first direction. This eliminates the displacement deviation of workpiece 50 in the first and second directions, further ensuring the relative positional accuracy of the first shearing component 41 and the second shearing component 42 with the sprue 501 of workpiece 50, further improving the stability of the shearing fixture, further improving the smoothness of the sprue removal, and avoiding dimensional deviation or shape distortion caused by offset, which could lead to burrs or incomplete shearing at the sprue removal.

[0083] In some embodiments, to ensure that the first shearing component 41 can stably shear one side of the sprue 501, such as... Figure 1 and Figure 4 As shown, this embodiment proposes a structural composition of the first pruning component 41:

[0084] The first shearing component 41 includes a first driving component 411, a second driving component 412, and a first air shear 413;

[0085] The output terminal of the first drive component 411 is connected to the second drive component 412, and the output terminal of the second drive component 412 is connected to the first air shear 413.

[0086] The first driving component 411 drives the second driving component 412 to move along the second direction, so that one side of the water outlet 501 is within the cutting range of the first air shear 413; the second driving component 412 drives the first air shear 413 to open / close.

[0087] It should be noted that the first drive component 411 and the second drive component 412 proposed in this embodiment are both preferably cylinder components.

[0088] Thus, when the fifth drive assembly 203 moves the sliding seat 201 toward the fixed seat 202, the length of the clamping space along the second direction is reduced. At this time, the first air shear 413 is in the open state, and the cutting range of the first air shear 413 is at the same horizontal plane as the corresponding sprue 501. Then, the sixth drive assembly 213 moves the push block 212 toward the second limit block 211 to reduce the length of the clamping space along the first direction, so that the clamping space stably clamps the workpiece 50. At this time, the sprue 501 of the workpiece 50 is directly below the anti-bounce device 30, and the part between the middle and one side of the sprue 501 is inside the open first air shear 413.

[0089] Then, the control device 60 activates the first drive assembly 411, causing it to drive the second drive assembly 412 and the first air shear 413 to move along the second direction to one side of the sprue 501, so that one side of the sprue 501 is within the open first air shear 413 (equivalent to one side of the sprue 501 being within the shearing range of the first air shear 413). Then, the control device 60 activates the second shearing assembly 42, so that the other side of the sprue 501 is within the shearing range of the second shearing assembly 42. Then, the control device 60 activates the second drive assembly 412, so that the other side of the sprue 501 is within the shearing range of the second shearing assembly 42. 412 drives the first air shear 413 to close, so as to cut one side of the sprue 501 from the workpiece 50. At the same time, the control device 60 controls the second shearing component 42 to cut the other side of the same sprue 501 from the workpiece 50. After the shearing is completed, the control device 60 controls the first drive component 411 (including the first air shear 413 to return to the open state) and the second shearing component 42 to return to the open state. After the operator removes the final product - the decorative strip - from the clamping space, the control device 60 controls the fifth drive component 203 and the sixth drive component 213 to return to the open state, so as to perform the next shearing action of the workpiece 50.

[0090] In other embodiments, to ensure the smoothness of the displacement of the first driving component 411 along the second direction, such as... Figure 4 As shown, the first shearing component 41 also includes a first base 414, which faces the first drive component 411 and extends along the second direction with a first slide rail 415; the first drive component 411 is fitted with a first slide groove (not shown, same throughout) corresponding to the first slide rail 415.

[0091] The first drive component 411 forms a first sliding pair along the second direction through a clearance fit between the first slide groove and the corresponding first slide rail 415.

[0092] In some embodiments, the second shearing component 42 is guaranteed to stably shear off the other side of the sprue 501, such as... Figure 1 and Figure 5 As shown, this embodiment proposes a structural composition of the second pruning component 42:

[0093] The second shearing component 42 includes a third drive component 421, a fourth drive component 422, and a second air shear 423;

[0094] The output end of the third drive component 421 is connected to the fourth drive component 422, and the output end of the fourth drive component 422 is connected to the second air shear 423.

[0095] The third drive component 421 drives the fourth drive component 422 to move along the first direction, so that the other side of the sprue 501 is within the shearing range of the second air shear 423; the fourth drive component 422 drives the second air shear 423 to open / close.

[0096] It should be noted that the third drive component 421 and the fourth drive component 422 proposed in this embodiment are both preferably cylinder components.

[0097] Thus, when the fifth drive assembly 203 moves the sliding seat 201 toward the fixed seat 202, the length of the clamping space along the second direction is reduced. At this time, the first air shear 413 is in the open state, and the cutting range of the first air shear 413 and the second air shear 423 are at the same horizontal plane as the corresponding sprue 501. Then, the sixth drive assembly 213 moves the push block 212 toward the second limit block 211 to reduce the length of the clamping space along the first direction, thereby making the clamping space stably clamp the workpiece 50. At this time, the sprue 501 of the workpiece 50 is directly below the anti-bounce device 30, and the part between the middle and one side of the sprue 501 is inside the open first air shear 413. The other side of the sprue 501 is at the same height as the open second air shear 423 and is spaced apart along the first direction.

[0098] Then, the control device 60 activates the first drive assembly 411, causing it to drive the second drive assembly 412 and the first air shear 413 to move along the second direction to one side of the sprue 501, so that one side of the sprue 501 is within the open state of the first air shear 413 (equivalent to one side of the sprue 501 being within the shearing range of the first air shear 413); simultaneously, the control device 60 activates the third drive assembly 421, causing it to drive the fourth drive assembly 422 and the second air shear 423 to move along the first direction to the other side of the sprue 501, so that the other side of the sprue 501 is within the open state of the second air shear 423 (equivalent to the other side of the sprue 501 being within the shearing range of the second air shear 423); then The control device 60 then simultaneously activates all the second drive components 412 and the fourth drive components 422, so that the second drive component 412 drives the first air shear 413 to close, and the fourth drive component 422 drives the second air shear 423 to close, so that both sides of all the sprues 501 are cut off from the workpiece 50 at the same time. After the cutting is completed, the control device 60 controls the first air shear 413 and the second air shear 423 to return to the open state. Then the control device 60 controls the first drive component 411 and the third drive component 421 to reset. After the operator removes the final product - the decorative strip - from the clamping space, the control device 60 controls the fifth drive component 203 and the sixth drive component 213 to reset so as to perform the cutting action of the next workpiece 50.

[0099] In other embodiments, to ensure the smoothness of the displacement of the third drive component 421 along the first direction, such as... Figure 5 As shown, the second shearing component 42 also includes a second base 424, which faces the third drive component 421 and extends along the first direction with a second slide rail 425; the third drive component 421 is fitted with a second slide groove (not shown, same throughout) corresponding to the second slide rail 425.

[0100] The third drive component 421 forms a second sliding pair along the first direction through a clearance fit between the second slide groove and the corresponding second slide rail 425.

[0101] In some embodiments, such as Figure 2 As shown, the anti-bounce device 30 includes a baffle 301 that extends above the corresponding water inlet 501.

[0102] It should be noted that the baffle 301 is preferably a right-angled curved plate. Of course, the shape of the baffle 301 can also be U-shaped, semi-circular, or other shapes suitable for blocking the unpredictable ejection motion generated by the shearing moment of the sprue 501. This is not limited here.

[0103] The vertical side of the baffle 301 is connected to the base 10, and the horizontal side of the baffle 301 extends to the upper part of the middle of the corresponding sprue 501, so as to better block the unpredictable ejection motion generated by the shearing moment of the sprue 501, prevent secondary injury, ensure the safety of operators or surrounding personnel, and reduce safety risks.

[0104] In some embodiments, the present invention also proposes an air conditioner assembly line, wherein the air conditioner assembly line includes the shearing fixture described above.

[0105] Thus, when other tooling in the air conditioner assembly line needs to use decorative strips during the air conditioner installation process, the operator or other automated machinery (robotic arm) will place the workpiece 50 into the clamping space, and then press the start button in the control device 60. The control device 60 will then activate the fifth drive component 203, so that the fifth drive component 203 will move the sliding seat 201 toward the fixed seat 202 together to reduce the length of the clamping space along the second direction. Then the control device 60 will activate the sixth drive component 213, so that the sixth drive component 213 will move the push block 212 toward the second limit block 211 to reduce the length of the clamping space along the first direction, thereby making the clamping space stably clamp the workpiece 50. At this time, the sprue 501 of the workpiece 50 is directly below the corresponding baffle 301, and the part between the middle and one side of the sprue 501 is in the open state of the first air shear 413. The other side of the sprue 501 is at the same height as the open state of the second air shear 423 and is spaced apart along the first direction.

[0106] Then, control device 60 activates the first drive assembly 411, causing it to drive the second drive assembly 412 and the first air shear 413 to move along the second direction to one side of the sprue 501, so that one side of the sprue 501 is inside the open air shear 413; simultaneously, control device 60 activates the third drive assembly 421, causing it to drive the fourth drive assembly 422 and the second air shear 423 to move along the first direction to the other side of the sprue 501, so that the other side of the sprue 501 is inside the open air shear 423; then control device 60 simultaneously activates all the second drive assemblies 412 and the fourth drive assembly 422. The second drive assembly 412 drives the first air shear 413 to close, and the fourth drive assembly 422 drives the second air shear 423 to close, so that both sides of all the sprues 501 are simultaneously cut off from the workpiece 50. After the cutting is completed, the control device 60 controls the first air shear 413 and the second air shear 423 to return to the open state. Then the control device 60 controls the first drive assembly 411 and the third drive assembly 421 to reset. After the operator takes the final product - the decorative strip - out of the clamping space, the control device 60 controls the fifth drive assembly 203 and the sixth drive assembly 213 to reset so as to carry out the cutting action of the next workpiece 50.

[0107] Furthermore, if a malfunction occurs during any period of the shearing fixture or in any device, the control device 60 will issue a stop command based on the fault signal, causing the entire shearing fixture to stop in tandem. After the fault is repaired, the operator can manually restart the shearing fixture and restore the parameters to their pre-stop state.
