[0003] In the prior art, stamping of metal clamps is mostly done by stamping, that is, stamping a metal sheet into a specified shape through a die. However, most of the forming equipment in the prior art can only process one metal sheet at a time, and metal clamps are usually used in pairs, and the two metal clamps need to be accurately matched after processing. However, due to possible errors in processing, the two metal clamps processed individually may not be completely matched during the later pairing process. Summary of the invention

[0006] A forming module, wherein the forming module comprises a driving member mounted on a mounting frame, the telescopic end of the driving member is connected to a top plate, a forming column is mounted on the bottom surface of the top plate, and a slot matching the forming column is also provided on the frame, and an inclined surface is symmetrically provided on the bottom of the forming column;

[0007] A positioning module, wherein two groups of positioning modules are provided, and the two groups of positioning modules are symmetrically arranged on both sides of the slot, the positioning module comprises a mounting plate installed on the frame, a side plate is provided on the side of the mounting plate close to the slot, a guide rod is provided on the side of the side plate close to the mounting plate, the guide rod is slidably installed on the side plate (along the X direction), and a first spring is also provided between the guide rod and the mounting plate, a first electromagnet is also provided on the mounting plate, two clamping plates are symmetrically provided on the side of the side plate close to the slot, the clamping plate is slidably installed on the side plate (along the Y direction), and a control unit for driving two clamping plates in the same group of positioning modules to slide towards or in the opposite direction at the same time is also provided on the top plate;

[0008] The auxiliary forming unit comprises two pre-bending rods symmetrically installed in the slots, the pre-bending rods are slidably installed in the slots along the vertical direction, and the pre-bending rods are connected to the bottom of the slots through a second spring, and the top of the pre-bending rods is provided with a V-shaped groove with matching inclined surface.

[0009] According to a further technical solution, the driving member is a hydraulic telescopic rod.

[0010] According to a further technical solution, a sliding seat is provided at the bottom of each clamping plate, the sliding seat is slidably installed on the bottom of the clamping plate (along the X direction), and a sliding groove is also provided on the frame for the sliding seat to slide (along the Y direction).

[0011] A further technical solution is that the control unit is provided with two groups, which are respectively connected to the two groups of positioning modules, and the control unit includes two extension seats symmetrically installed on both sides of the top plate, and the first connecting seat is slidably installed in the extension seat (along the Y direction), and the extension seat is also provided with a third spring connected to the first connecting seat, and the extension seat is also provided with a second electromagnet, the bottom of the first connecting seat is hinged with a connecting rod, the end of the connecting rod away from the first connecting seat is hinged to the second connecting seat, and the second connecting seat is slidably installed on the top of the clamping plate (along the X direction).

[0012] According to a further technical solution, each positioning module is also provided with a punching unit for punching holes in the processed metal clamp.

[0013] According to a further technical solution, the punching unit comprises a mounting seat mounted on a clamping plate, a telescopic member is mounted on the mounting seat, a telescopic end of the telescopic member is connected to a punching head, and a punching hole is opened at a corresponding position on the other clamping plate.

[0014] According to a further technical solution, the second electromagnet starts and stops synchronously with the first electromagnet.

[0015] A metal hoop forming device provided by an embodiment of the present invention, in the initial state, the first electromagnet is in the power-on state, at which time the side plate is adsorbed by the first electromagnet and cannot move along the X direction. When in use, the operator only needs to place two metal sheets on both sides of the auxiliary forming unit, and then start the driving member, which can drive the top plate to move downward, and the top plate drives the forming column to move downward synchronously, so that the inclined surface at the bottom of the forming column is inserted into the V-shaped groove. In this process, the top plate can drive the two clamping plates in each group of positioning modules to move toward each other through the control unit, so as to clamp one end of the two metal sheets, and both ends of the metal sheets can be fixed by the two groups of positioning modules. At the same time, the first electromagnet will be powered off, and the elastic force provided by the first spring will push the side plate to move toward the side close to the slot, and the side plates in the two groups of positioning modules will cooperate with each other, so that the two ends of the two metal sheets can be aligned. When the two ends of the metal sheet are clamped, since the pre-bent rod is located between the two metal sheets, the metal sheet will be deformed to produce a gap, which is convenient for the forming column to be inserted between the two metal sheets. As the top plate drives the forming column to continue to move downward, the forming column will gradually be inserted between the two sheets, thereby forming the two metal sheets through the side walls of the forming column and processing them into metal hoops. In this process, the forming column will simultaneously push the pre-bent rod downward, and eventually make the top of the pre-bent rod not higher than the lowest point of the metal sheet, which will not affect the forming process. In addition, the elastic force provided by the first spring can make the side plate always be subjected to a force toward the slot. When the two ends of the metal sheet move due to deformation, the side plate will always abut against its end, causing the two metal sheets to be misaligned. The device can complete the processing of a pair of hoops at one time, and the formed hoops have a high matching degree. At the same time, the forming and punching of the metal hoop can be realized at one time, which effectively simplifies the processing process of the metal hoop and greatly improves the work efficiency.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1-Figure 3 As shown, a metal hoop forming device provided by an embodiment of the present invention includes a frame 1, on which a mounting frame 12 is mounted; and further includes:

[0026] The forming module 2 comprises a driving member 21 mounted on the mounting frame 12, the telescopic end of the driving member 21 is connected to a top plate 22, a forming column 23 is mounted on the bottom surface of the top plate 22, and a slot 11 matching the forming column 23 is further provided on the frame 1, and an inclined surface 231 is symmetrically provided on the bottom of the forming column 23;

[0027] A positioning module 3, wherein two groups of the positioning modules 3 are provided, and the two groups of the positioning modules 3 are symmetrically arranged on both sides of the slot 11, the positioning module 3 comprises a mounting plate 34 mounted on the frame 1, a side plate 31 is provided on the side of the mounting plate 34 close to the slot 11, a guide rod 35 is provided on the side of the side plate 31 close to the mounting plate 34, the guide rod 35 is slidably installed on the side plate 31 (along the X direction), and a first spring 37 is further provided between the guide rod 35 and the mounting plate 34, a first electromagnet 36 is further provided on the mounting plate 34, two clamping plates 32 are symmetrically provided on the side of the side plate 31 close to the slot 11, the clamping plates 32 are slidably installed on the side plate 31 (along the Y direction), and a control unit 5 for driving the two clamping plates 32 in the same group of positioning modules 3 to slide towards or in the opposite directions at the same time is further provided on the top plate 22;

[0028] The auxiliary forming unit 4 includes two pre-bending rods 41 symmetrically installed in the slot 11, and the pre-bending rods 41 are slidably installed in the slot 11 along the vertical direction, and the pre-bending rods 41 are connected to the bottom of the slot 11 through a second spring 42, and the top of the pre-bending rod 41 is provided with a V-shaped groove 411 matching the inclined surface 231.

[0029] In the embodiment of the present invention, the driving member 21 is a hydraulic telescopic rod, and the 27 is a tension spring. In the initial state, the first electromagnet 36 is in an energized state, at which time the side plate 31 is adsorbed by the first electromagnet 36 and cannot move along the X direction. When in use, the operator only needs to place the two metal sheets on both sides of the auxiliary forming unit 4, and then start the driving member 21. The driving member 21 can drive the top plate 22 to move downward, and the top plate 22 drives the forming column 23 to move downward synchronously, so that the inclined surface 231 at the bottom of the forming column 23 is inserted into the V-shaped groove 411. In this process, the top plate 22 can drive the two clamping plates 32 in each group of positioning modules 3 to move toward each other through the control unit 5, so as to clamp one end of the two metal sheets, and both ends of the metal sheets can be fixed by the two groups of positioning modules 3. At the same time, the first electromagnet 36 will be powered off, and the elastic force provided by the first spring 37 will push the side plate 31 to move toward the side close to the slot 11. The two sets of side plates 31 in the positioning modules 3 cooperate with each other to align the two ends of the two metal sheets. When the two ends of the metal sheet are clamped, the pre-bent rod 41 is located between the two metal sheets, so the metal sheet will be deformed to produce a gap, which is convenient for the forming column 23 to be inserted between the two metal sheets. As the top plate 22 drives the forming column 23 to continue to move downward, the forming column 23 will gradually be inserted between the two sheets, so that the two metal sheets are formed through the side wall of the forming column 23 and processed into a metal hoop. In this process, the forming column 23 will simultaneously push the pre-bent rod 41 to move downward, and finally make the top of the pre-bent rod 41 not higher than the lowest point of the metal sheet, which will not affect the forming process. In addition, the elastic force provided by the first spring 37 can always cause the side plate 31 to be subjected to a force toward the slot 11. When the two ends of the metal sheet move due to deformation, the side plate 31 will always abut against its ends, causing the two metal sheets to be misaligned.

[0030] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, a sliding seat 33 is provided at the bottom of each clamping plate 32, and the sliding seat 33 is slidably installed at the bottom of the clamping plate 32 (along the X direction), and a sliding groove for the sliding seat 33 (along the Y direction) to slide is also provided on the frame 1.

[0031] In the embodiment of the present invention, when the clamping plate 32 slides on the side plate 31 along the Y direction, the clamping plate 32 can drive the sliding seat 33 to slide synchronously along the slide groove on the frame 1. When the side plate 31 pushes the clamping plate 32 to move toward or away from the slot 11 (i.e., along the X direction), the sliding seat 33 will slide relative to the sliding seat 33, and will not move synchronously along the X direction. By providing the sliding seat 33, the stability of the clamping plate 32 during movement can be increased.

[0032] like Figure 1, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, as a preferred embodiment of the present invention, the control unit 5 is provided with two groups, which are respectively connected to the two groups of positioning modules 3, and the control unit 5 includes two extension seats 51 symmetrically installed on both sides of the top plate 22, and a first connecting seat 53 is slidably installed in the extension seat 51 (along the Y direction), and a third spring 54 connected to the first connecting seat 53 is also provided in the extension seat 51, and a second electromagnet 55 is also provided in the extension seat 51, and a connecting rod 52 is hinged at the bottom of the first connecting seat 53, and one end of the connecting rod 52 away from the first connecting seat 53 is hinged on the second connecting seat 56, and the second connecting seat 56 is slidably installed (along the X direction) on the top of the clamping plate 32.

[0033] In the embodiment of the present invention, the third spring 54 is a compression spring. In the initial state, the second electromagnet 55 is energized, and the first connection seat 53 can be adsorbed by the second electromagnet 55, so that the first connection seat 53 cannot slide in the extension seat 51. At this time, as the top plate 22 moves downward, the first connection seat 53 can drive the connecting rod 52 to rotate around the hinge point on the first connection seat 53 while moving downward, and the connecting rod 52 can drive the clamping plate 32 to slide along the Y direction through the second connection seat 56, so that the two clamping plates 32 in the same group of positioning modules 3 move toward each other at the same time, thereby clamping the two metal sheets. And when the two clamping plates 32 clamp the metal sheets, the inclined surface 231 at the bottom of the forming column 23 has not yet contacted the 4 slots 11 at the top of the pre-bent rod 41. When the two clamping plates 32 clamp the metal sheet, the second electromagnet 55 is de-energized. At this time, as the top plate 22 continues to move downward, due to the reaction of the clamping plate 32 below, the connecting rod 52 will rotate around the hinge point on the second connecting seat 56, thereby pushing the first connecting seat 53 to slide in the extension seat 51 and compressing the third spring 54.

[0034] During the upward movement of the top plate 22, the elastic restoring force of the third spring 54 causes the first connection seat 53 to move toward the side close to the second electromagnet 55 until the first connection seat 53 contacts the second electromagnet 55 again, at which time the second electromagnet 55 is energized to adsorb the first connection seat 53. Then, the corresponding clamping plate 32 can be driven by the connecting rod 52 to return to the initial position in the Y-upward direction.

[0035] like Figure 1-Figure 3As shown, as a preferred embodiment of the present invention, each positioning module 3 is further provided with a punching unit 6 for punching the processed metal clamp. After the metal sheet is processed into the clamp, the punching unit 6 can be used to punch holes on both sides of the clamp, thereby achieving one-time complete processing of the clamp, without the need to remove the clamp for a separate punching operation.

[0036] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the punching unit 6 includes a mounting base 61 installed on a clamping plate 32, a telescopic member 62 is installed on the mounting base 61, the telescopic end of the telescopic member 62 is connected to a punching head 63, and a punching hole 64 is opened at a corresponding position on the other clamping plate 32.

[0037] In the embodiment of the present invention, the telescopic member 62 is also a hydraulic telescopic rod. In the initial state, the telescopic member 62 is in a retracted state. When the forming column 23 completes the forming process of the metal sheet, it is only necessary to control the telescopic member 62 to extend, and the telescopic member 62 can drive the punching head 63 to move synchronously, so that the punching head 63 passes through the two metal sheets and is inserted into the punching hole 64, thereby completing the punching and punching of the metal hoop.

[0038] As a preferred embodiment of the present invention, the second electromagnet 55 and the first electromagnet 36 maintain synchronous start and stop, that is, in the initial state, the second electromagnet 55 and the first electromagnet 36 are both in the power-on state, and when the second electromagnet 55 is powered off, the first electromagnet 36 will be powered off synchronously, and when the second electromagnet 55 is powered on and started, the first electromagnet 36 will also be started synchronously.

[0039] Working principle: In the initial state, the first electromagnet 36 is in the energized state, and the side plate 31 is adsorbed by the first electromagnet 36 and cannot move along the X direction. At the same time, the second electromagnet 55 is energized, and the first connecting seat 53 can be adsorbed by the second electromagnet 55, so that the first connecting seat 53 cannot slide in the extension seat 51. When in use, the operator only needs to place two metal sheets on both sides of the auxiliary forming unit 4, and then start the driving member 21. The driving member 21 can drive the top plate 22 to move downward, and the top plate 22 drives the forming column 23 to move downward synchronously, so that the inclined surface 231 at the bottom of the forming column 23 is inserted into the V-shaped groove 411. In this process, as the top plate 22 moves downward, the first connecting seat 53 can drive the connecting rod 52 to rotate around the hinge point on the first connecting seat 53 while moving downward, and the connecting rod 52 can drive the clamping plate 32 to slide along the Y direction through the second connecting seat 56, so that the two clamping plates 32 in the same group of positioning modules 3 move toward each other at the same time, thereby clamping the two metal sheets. After the two clamping plates 32 clamp the metal sheets, the second electromagnet 55 is powered off. At this time, as the top plate 22 continues to move downward, due to the reaction of the clamping plate 32 below, the connecting rod 52 will rotate around the hinge point on the second connecting seat 56, thereby pushing the first connecting seat 53 to slide in the extension seat 51 and compressing the third spring 54, which will not interfere with the movement of the top plate 22. At the same time, the first electromagnet 36 will be powered off, and the elastic force provided by the first spring 37 will push the side plate 31 to move toward the side close to the slot 11. The two sets of side plates 31 in the positioning modules 3 cooperate with each other to align the two ends of the two metal sheets. When the two ends of the metal sheet are clamped, the pre-bent rod 41 is located between the two metal sheets, so the metal sheet will be deformed to produce a gap, which is convenient for the forming column 23 to be inserted between the two metal sheets. As the top plate 22 drives the forming column 23 to continue to move downward, the forming column 23 will gradually be inserted between the two sheets, so that the two metal sheets are formed through the side wall of the forming column 23 and processed into a metal hoop. In this process, the forming column 23 will simultaneously push the pre-bent rod 41 to move downward, and finally make the top of the pre-bent rod 41 not higher than the lowest point of the metal sheet, which will not affect the forming process. In addition, the elastic force provided by the first spring 37 can always cause the side plate 31 to be subjected to a force toward the slot 11. When the two ends of the metal sheet move due to deformation, the side plate 31 will always abut against its ends, causing the two metal sheets to be misaligned. After the forming column 23 completes the forming process of the metal sheet, it is only necessary to control the extension of the telescopic member 62, and the telescopic member 62 can drive the punching head 63 to move synchronously, so that the punching head 63 passes through the two metal sheets and is inserted into the punching hole 64, thereby completing the punching and punching of the metal clamp, realizing a one-time complete processing of the clamp, and no longer needing to remove the clamp for a separate punching operation.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
