Description

Technical Field

[0001] This invention relates to the field of sheet metal transfer technology, and in particular to a U-shaped cross-section sheet metal transfer mechanism and sheet metal loading method. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Products processed through sheet metal processing are called sheet metal parts.

[0003] U-shaped cross-section sheet metal parts are mostly used to connect and reinforce joints, providing localized reinforcement at the joints. The fabrication process for this structure includes... Figure 1 As shown, the U-shaped sheet metal part needs to be fed into the mold groove of the stamping equipment with the opening facing upward. Then, the folded plate on the side of the joint is inserted into the opening of the U-shaped sheet metal part. Subsequently, the stamping equipment is used to perform the pressing and buckling process to achieve the connection and edge binding.

[0004] These U-shaped sheet metal parts must be loaded with the opening facing upwards. According to the operating procedures, for safety reasons, the parts cannot be loaded by hand. Tools must be used to grab and place the parts. However, the current tools cannot hold the U-shaped sheet metal parts in place well, making them prone to rotation and tipping during the transfer process, and making it impossible to keep the opening facing upwards for loading. Summary of the Invention

[0005] To overcome the problems existing in related technologies, the present invention provides a U-shaped cross-section sheet metal transfer mechanism and sheet metal loading method, which can realize the rapid and stable gripping and release of long strip U-shaped cross-section sheet metal parts, ensuring that the magnet is transferred with the slot facing upward.

[0006] One of the objectives of this invention is to provide a U-shaped cross-section sheet metal transfer mechanism. The U-shaped cross-section sheet metal part includes a base plate, the two sides of which are bent upward to form side plates. The side plates and the base plate together form a groove, and the width of the opening end of the groove is not greater than the width of the bottom end of the groove.

[0007] Includes transplanting base and magnet;

[0008] The transplanting base is provided with a receiving area for magnetically fixing a U-shaped sheet metal part. The receiving area is provided with a limiting member for restricting the rotation and tilting of the U-shaped sheet metal part. The limiting member is connected to the transplanting base. After magnetic attraction, if the U-shaped sheet metal part becomes loose on one side, it cannot rotate or tilt further due to the obstruction of the limiting member, thus keeping the groove facing upward.

[0009] The magnet is mounted on the transplanting base. The lower end of the magnet can move into or out of the receiving area. The lower end face of the magnet can magnetically attract the slot end face of the U-shaped cross-section sheet metal part.

[0010] When the magnet moves upward, the U-shaped sheet metal part that is attracted by the magnet will be separated from the magnet by the transfer seat, thus realizing the material dropping.

[0011] In a preferred embodiment of the present invention, the limiting member includes a first limiting part and / or a second limiting part;

[0012] The first limiting part is located outside the slot of the U-shaped cross-section sheet metal part that is magnetically attached to the magnet. The first limiting part can guide when gripping the U-shaped cross-section sheet metal part. In conjunction with magnetic gripping, it is conducive to quick orientation and removal of parts. The first limiting part can limit the outer end face of the side plate of the U-shaped cross-section sheet metal part after magnetic gripping.

[0013] The second limiting part can extend into the slot of the U-shaped sheet metal part magnetically attached to the magnet; the second limiting part can extend into the slot after the magnetically attached U-shaped sheet metal part is magnetically attached, so as to limit the inner end of the side plate of the U-shaped sheet metal part.

[0014] The above structure ensures that even if the contact position on one side of the U-shaped sheet metal part becomes loose, the path of the part flipping outward is blocked by the first limiting part and the second limiting part, thereby keeping the groove of the U-shaped sheet metal part facing upward.

[0015] In a preferred embodiment of the present invention, at least one of the first limiting portions is arranged along the length direction of the accommodating area.

[0016] In a preferred embodiment of the present invention, an auxiliary magnet is installed at the lower end of the second limiting part, and the auxiliary magnet can be magnetically attracted to the bottom end face of the slot of the U-shaped cross-section sheet metal part.

[0017] In a preferred embodiment of the present invention, the first limiting part includes two symmetrically arranged outer limiting members, which are arranged along the width direction of the accommodating area.

[0018] Two external limiting members and the lower side of the transplanting seat form a receiving area for accommodating a U-shaped sheet metal part. The cross-sectional shape of the receiving area is adapted to the cross-sectional shape of the U-shaped sheet metal part. The lower end of the magnet can move down and extend into the upper part of the receiving area.

[0019] In a preferred embodiment of the present invention, the side of the outer limiting member facing the receiving area forms a limiting surface, and the limiting surface is adapted to the outer side of the slot, thereby providing adaptive guidance and restriction to the outer side of the side plate.

[0020] In a preferred embodiment of the present invention, the second limiting part includes at least one inner limiting member, the inner limiting member being arranged along the length direction of the accommodating area, and the outer limiting member being arranged along the width direction of the accommodating area.

[0021] The inner limiting member can extend into the slot of the U-shaped cross-section sheet metal part that is magnetically attracted within the accommodating area to limit the U-shaped cross-section sheet metal part.

[0022] In a preferred embodiment of the present invention, the transplanting base is a frame, the limiting member is installed on the side of the frame, the magnet is disposed inside the frame, and a drive plate for driving the magnet to move is disposed above the transplanting base.

[0023] When the magnet is in the magnetic attraction position, the lower end face of the magnet is horizontal and extends into the receiving area.

[0024] When the magnet is in the unloading position, the lower end face of the magnet is above the receiving area. At this time, the frame acts as a block to separate the magnet from the U-shaped section sheet metal part.

[0025] In a preferred embodiment of the present invention, the drive plate includes a base plate and a pressing handle connected in sequence. The magnet is mounted on the lower side of the base plate, and the middle part of the pressing handle is hinged to the transplanting seat. By operating the pressing handle, the magnet is driven to move.

[0026] In a preferred embodiment of the present invention, a transplanting handle is provided below the pressing handle, the transplanting handle is connected to the transplanting base, the transplanting handle is used by the operator to hold and operate, so as to perform transplanting, and the pressing handle is hinged to the transplanting handle.

[0027] In a preferred embodiment of the present invention, the pressing handle is bent in the middle, the inner end of the pressing handle is a connecting plate part and the outer end is a pressing plate part, the bent part of the pressing handle is hinged to the transplanting handle, and the included angle between the connecting plate part and the pressing plate part is an obtuse angle.

[0028] In a preferred embodiment of the present invention, in order to ensure a stable magnetic attraction and a strong magnetic force, at least one magnet is provided, and the magnet is arranged along the length of the receiving area.

[0029] The second objective of this invention is to provide a sheet metal loading method, based on the aforementioned U-shaped cross-section sheet metal transfer mechanism, comprising the following steps:

[0030] Adjust the orientation of the U-shaped section sheet metal part so that the groove faces upward;

[0031] Move the transplanter down to fit the side of the U-shaped sheet metal part against the top, so that the magnet can magnetically attract the U-shaped sheet metal part.

[0032] The movable transfer stand is used to transfer U-shaped section sheet metal parts to a designated location;

[0033] Move the magnet upwards to separate it from the U-shaped sheet metal part;

[0034] Remove the transplanting base and complete the feeding.

[0035] The beneficial effects of this invention are as follows:

[0036] It can quickly and stably grasp and release long, U-shaped sheet metal parts;

[0037] The limiting component can restrict the rotation and tilting of U-shaped sheet metal parts after magnetic attraction;

[0038] The limiting component does not affect the blanking of U-shaped sheet metal parts, and there is no need for workers to repeatedly adjust the position of U-shaped sheet metal parts after relocation;

[0039] The first limiting part can guide the gripping of U-shaped sheet metal parts. In conjunction with magnetic gripping, it is conducive to quick orientation and removal of parts. After the U-shaped sheet metal parts are magnetically gripped, the outer end face of the side plate of the U-shaped sheet metal parts can be limited to prevent the sheet metal parts from rotating and tipping over during the transfer process.

[0040] The second limiting part can extend into the groove behind the magnetic U-shaped sheet metal part to limit the inner end of the side plate of the U-shaped sheet metal part and prevent the sheet metal part from rotating and tipping over during the transplanting process.

[0051] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0052] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0053] It should be understood that although the terms "first," "second," "third," etc., may be used in this invention to describe various types of information, these information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as information, and similarly, information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0054] Example 1

[0055] U-shaped cross-section sheet metal parts are mostly used to connect and reinforce joints, providing localized reinforcement at the joints. The fabrication process for this structure includes... Figure 1 As shown, the U-shaped sheet metal part needs to be fed into the mold groove 1 of the stamping equipment with the opening facing upward. Then, the folded plate of the joint end 2 is inserted into the opening of the U-shaped sheet metal part. Subsequently, the stamping equipment is used to perform the pressing and buckling process to achieve the connection and edge binding.

[0056] These U-shaped sheet metal parts must be loaded with the opening facing upwards. According to the operating procedures, for safety reasons, the parts cannot be loaded by hand. Tools must be used to grab and place the parts. However, the current tools cannot hold the U-shaped sheet metal parts in place well, making them prone to rotation and tipping during the transfer process, and making it impossible to keep the opening facing upwards for loading.

[0057] Common methods for loading sheet metal parts include clamping or magnetic attraction, but these methods are not suitable for loading U-shaped sheet metal parts. For example... Figure 2 As shown, if clamping tool 4 is used to directly clamp a U-shaped sheet metal part, the part is very easy to rotate and tip over, and it is impossible to keep the opening facing upwards. Figure 3 As shown, when using the magnetic tool 5 to directly grasp the U-shaped sheet metal part using magnetic attraction, only the upper side surface of the U-shaped sheet metal part contacts the magnet 7. This means that only two lines of the U-shaped sheet metal part are in contact with the magnet 7, resulting in a small contact area and unstable magnetic attraction. During part transfer, the contact point on one side is prone to loosening, causing the part to flip. After the part flips, its side plate is magnetically attracted to the magnet 7, making it impossible to maintain the upward orientation of the opening during unloading.

[0058] To address the aforementioned issues, this embodiment provides a U-shaped cross-section sheet metal transfer mechanism, which enables rapid and stable gripping and release of long U-shaped cross-section sheet metal parts, ensuring that the magnet 7 is transferred with the slot facing upwards.

[0059] like Figure 3-7 As shown, a U-shaped cross-section sheet metal part transfer mechanism is provided. The U-shaped cross-section sheet metal part 3 includes a base plate 10. The base plate 10 is bent upward on both sides to form side plates. The side plates on both sides and the base plate 10 form a groove. The width of the opening end of the groove is not greater than the width of the bottom end of the groove.

[0060] Specifically, the transplanting mechanism includes a transplanting base 6 and a magnet 7;

[0061] The transplanting base 6 is provided with a receiving area for magnetically fixing the U-shaped cross-section sheet metal part 3. The receiving area is provided with a limiting member for restricting the rotation and tilting of the U-shaped cross-section sheet metal part 3. The limiting member is connected to the transplanting base 6.

[0062] The magnet 7 is mounted on the transfer base 6. The lower end of the magnet 7 can move into or out of the receiving area, and the lower end face of the magnet 7 can magnetically attract the slot end face of the U-shaped cross-section sheet metal part 3. When the magnet 7 moves upward, the magnetically attracted U-shaped cross-section sheet metal part 3 is blocked by the transfer base 6 and will separate from the magnet 7, thereby realizing the material dropping.

[0063] In this embodiment, the limiting member includes a first limiting part 8 and / or a second limiting part 9.

[0064] The first limiting part 8 is located outside the slot of the U-shaped cross-section sheet metal part 3 that is magnetically attracted to the magnet 7, to prevent the sheet metal part 3 from rotating and tipping over during the transplanting process, and is used to limit the outer side of the side plate.

[0065] The second limiting part 9 can extend into the slot of the U-shaped section sheet metal part 3 that is magnetically attracted to the magnet 7, and is used to limit the inner side of the side plate to prevent the sheet metal part 3 from rotating and tipping over during the transplanting process.

[0066] For example, such as Figure 8 As shown, even if the contact position on one side of the U-shaped cross-section sheet metal part 3 becomes loose, the path of the part flipping outward is restricted and blocked by the first limiting part 8 and the second limiting part 9, thereby keeping the groove of the U-shaped cross-section sheet metal part 3 facing upward.

[0067] In this embodiment, in order to ensure a stable magnetic attraction and a strong magnetic force, at least one magnet 7 is provided for gripping, and the magnet 7 is arranged along the length of the receiving area.

[0068] In this embodiment, to ensure sufficient limiting, at least one of the first limiting parts 8 is arranged along the length direction of the accommodating area.

[0069] When using:

[0070] First, move the transplanting base 6 down to fit its side against the upper end of the U-shaped section sheet metal part 3, so that the magnet 7 magnetically attracts the U-shaped section sheet metal part 3;

[0071] Then, the U-shaped section sheet metal part 3 can be transferred;

[0072] After the transplant is in place, the drive magnet 7 moves upward. The U-shaped sheet metal part 3 that is attracted by the magnet is blocked by the transplant seat 6 and will separate from the magnet 7, thereby realizing the material dropping.

[0073] This type of U-shaped cross-section sheet metal part 3 transfer mechanism can quickly and stably grasp and release long strip-shaped U-shaped cross-section sheet metal parts 3. The first limit part 8 and the second limit part 9 do not affect the unloading of the U-shaped cross-section sheet metal parts 3, eliminating the need for workers to repeatedly adjust the position of the U-shaped cross-section sheet metal parts 3 after transfer.

[0074] For example, an auxiliary magnet can be installed at the lower end of the second limiting part 9. The auxiliary magnet can be magnetically attracted to the bottom end face of the slot of the U-shaped cross-section sheet metal part 3. The total magnetic force of all auxiliary magnets is less than the weight of the U-shaped cross-section sheet metal part 3.

[0075] In practical applications, the magnetic attraction force is small due to the small contact area between the magnet 7 and the U-shaped cross-section sheet metal part 3. To ensure stable magnetic attraction and ease of use, the total magnetic force of all magnets 7 is 10-40 times the weight of the U-shaped cross-section sheet metal part 3. Taking the sheet metal connecting plate of the water tank shell as an example, the total length of the part is about 2m. The U-shaped cross-section sheet metal part 3 is selected for joint gripping by the transfer mechanism. Since the magnetic contact surface only has two lines in contact, the magnetic force is selected to be about 20 times the weight of the part.

[0076] For example, in practical applications, the first limiting part 8 and the second limiting part 9 can be retained or removed according to the actual part requirements. The number of the first limiting part 8 and the second limiting part 9 can be selected according to the actual part requirements. For example, when the contact area between the upper end face of the sheet metal part 3 and the magnet 7 is large, only at least one first limiting part 8 can be provided. For example, when the side plate is vertically arranged, only at least one second limiting part 9 can be provided.

[0077] In this embodiment, the first limiting part 8 includes two symmetrically arranged outer limiting members, which are connected to the transplanting base 6;

[0078] Two external limiting members and the lower side of the transplanting seat 6 form a receiving area for accommodating the U-shaped cross-section sheet metal part 3. The cross-sectional shape of the receiving area is adapted to the cross-sectional shape of the U-shaped cross-section sheet metal part 3. The lower end of the magnet 7 can move down and extend into the upper part of the receiving area.

[0079] In this embodiment, the side of the outer limiting member facing the receiving area forms a limiting surface, which is adapted to the outer side of the slot, thereby limiting the adaptability of the outer side of the side plate. It can provide a certain guidance when gripping the U-shaped sheet metal part 3. At the same time, when the magnetic attraction on one side is detached, the side plate cannot be flipped outward against the limiting surface.

[0080] In this embodiment, the second limiting part 9 includes at least one inner limiting member. Preferably, the inner limiting member is located between the two outer limiting members of a first limiting part 8. The inner limiting member can extend into the slot of the U-shaped cross-section sheet metal part 3 that is magnetically attracted in the accommodating area. When the magnetic attraction on one side is detached, the side plate cannot be flipped outward against the limiting surface.

[0081] In this embodiment, the transplanting seat 6 is a frame, and the inner and outer limiting members are both installed on the side of the frame. The magnet 7 is disposed inside the frame, and a drive plate for driving the magnet 7 to move is disposed above the transplanting seat 6. When the magnet 7 is in the magnetic attraction position, the lower end face of the magnet 7 is horizontal and extends into the receiving area. When the magnet 7 is in the unloading position, the lower end face of the magnet 7 is above the receiving area. At this time, the frame acts as a blocking mechanism to achieve the separation of the magnet 7 from the U-shaped section sheet metal part 3.

[0082] In this embodiment, the drive plate includes a base plate 10 and a pressing handle 11 connected in sequence. The magnet 7 is installed on the lower side of the base plate 10. The middle part of the pressing handle 11 is hinged to the transplanting seat 6. By operating the pressing handle 11, the base plate 10 is driven to move, thereby causing the magnet 7 to move.

[0083] In this embodiment, a transplanting handle 12 is provided below the pressing handle 11. The transplanting handle 12 is connected to the transplanting seat 6, and the pressing handle 11 and the transplanting handle 12 are hinged together. The transplanting handle 12 is used by the operator to hold and operate it for transplanting. Of course, the transplanting handle 12 can also be installed on the execution end of the robot arm to realize automatic transplanting. Due to the internal space limitation for transplanting and feeding the stamping equipment, manual feeding is preferred.

[0084] In this embodiment, the middle part of the pressing handle 11 is bent, the inner end of the pressing handle 11 is a connecting plate part, and the outer end is a pressing plate part. The bent part of the pressing handle 11 is hinged to the transplanting handle 12. The included angle between the connecting plate part and the pressing plate part is an obtuse angle. By pressing the pressing plate part, the hinge shaft of the substrate 10 is made to swing, thereby realizing the up and down movement of the magnet 7.

[0085] Example 2

[0086] This embodiment only describes the differences from Embodiment 1; the remaining technical features are the same as those in the above embodiment. Furthermore, a sheet metal feeding method is provided, based on the U-shaped cross-section sheet metal part 3 transfer mechanism in Embodiment 1, and is suitable for stamping equipment.

[0087] Sheet metal loading method includes the following steps:

[0088] Adjust the orientation of the U-shaped section sheet metal part 3 so that the groove faces upward;

[0089] Move the transplanting base 6 down to fit its side against the upper end of the U-shaped section sheet metal part 3, so that the magnet 7 magnetically attracts the U-shaped section sheet metal part 3;

[0090] The movable transfer seat 6 is used to transfer the U-shaped cross-section sheet metal part 3 to a designated position, which is the mold groove 1 of the stamping equipment;

[0091] Move magnet 7 upwards to separate magnet 7 from U-shaped sheet metal part 3;

[0092] Remove transplanting seat 6 to complete the feeding process.

[0093] In this embodiment, after the U-shaped section sheet metal part 3 is loaded, the folded plate of the joint end side 2 is inserted into the opening of the U-shaped section sheet metal part 3. Then, the pressing process is carried out by the stamping equipment to achieve the connection edge binding.

[0094] This sheet metal loading method uses a U-shaped cross-section sheet metal part 3 transfer mechanism for loading, which can quickly and stably grasp and release long strips of U-shaped cross-section sheet metal parts 3. It eliminates the need for workers to repeatedly adjust the position of the U-shaped cross-section sheet metal parts 3 after transfer, thereby improving the processing efficiency of stamping equipment.
