Description

Technical Field

[0001] This application relates to the field of belt buckle production equipment technology, and in particular to a belt buckle pin production equipment. Background Technology

[0002] The belt buckle pin is a key component of a belt buckle, typically a thin, elongated metal needle. Its function is to pass through the hole in the belt and engage with the buckle housing to achieve reliable fastening and easy release of the belt. Therefore, the manufacturing quality and efficiency of the belt buckle pin directly affect the production cycle and cost of the entire belt product.

[0003] In existing technologies, the production of belt buckle pins mostly relies on manual or semi-automated methods. Operators need to manually or semi-manually straighten coiled wires using a simple straightening device, and then send the straightened wires to the punching station where operators control the punching machine to stamp and form one end of the buckle pin. After that, another machine or the same punching machine with a different die is needed to cut the wires to obtain a single buckle pin blank of a predetermined length. The entire process has a low degree of automation and slow production efficiency.

[0004] Therefore, how to improve the production efficiency of belt buckle pins has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To improve the production efficiency of belt buckle pins, this application provides a belt buckle pin production equipment.

[0006] The belt buckle pin production equipment provided in this application adopts the following technical solution: A belt buckle pin production device includes a feeding tray, a straightening mechanism, a forming mechanism, and a feeding drive. A strip to be processed is wound on the feeding tray. The straightening mechanism is located on one side of the feeding tray and is used to straighten the strip. The forming mechanism is located on the side of the straightening mechanism away from the feeding tray, and includes a punch, a forming column, and a top bend. The punch is located above the strip, the forming column is located below the strip, and the top bend is located on one side of the forming column. The feeding drive is located between the straightening mechanism and the forming mechanism and is used to drive the strip into the forming mechanism.

[0007] By adopting the above technical solution, the material strip to be processed is collected by the feeding tray, and the material strip is straightened by the straightening mechanism. No manual labor is required. The straightening mechanism and the forming mechanism are combined. After the material strip is straightened by the straightening mechanism, it is directly fed into the forming mechanism, where it is formed by the punch, forming column and top bend. The material strip is directly formed. The feeding drive component set between the straightening mechanism and the forming mechanism drives the material strip to be fed. The whole process is automated without manual labor, which greatly improves the production efficiency of belt buckle pins.

[0008] Preferably, the straightening mechanism includes a first pressure roller and a second pressure roller, and there are multiple first pressure rollers and multiple second pressure rollers; the multiple first pressure rollers are horizontally arranged on both sides of the material belt; the multiple second pressure rollers are vertically arranged on both sides of the material belt.

[0009] By adopting the above technical solution, multiple first pressure rollers and multiple second pressure rollers are used to straighten the material strip in different directions. The first pressure rollers straighten the material strip in the horizontal direction, and the second pressure rollers straighten the material strip in the vertical direction, which facilitates the material strip to enter the forming mechanism for forming. At the same time, the first and second pressure rollers restrict the feeding position of the material strip to a certain extent, eliminating the need to restrict the two ends of the material strip, thus saving costs to a certain extent.

[0010] Preferably, the forming mechanism further includes an abutment block and a limiting block; the abutment block is disposed on the side of the punch away from the straightening mechanism, and the abutment block is used to limit the feeding length of the strip; the limiting block is disposed on the other side of the punch, and the limiting block has a through hole for the strip to pass through.

[0011] By adopting the above technical solution, the abutment block abuts against the end face of the strip during feeding, limiting the feeding degree of the strip and preventing the strip from being too long or too short, which would lead to poor forming effect and product defects, thus increasing the product qualification rate to a certain extent. The limiting block has through holes for the strip to pass through, which restricts the position of the strip and also restricts the position of the strip during stamping. Stamping can be completed without the need for the lower die to clamp, which not only saves costs but also reduces the footprint of the equipment and increases space utilization.

[0012] Preferably, the limiting block has a protrusion on the side near the punch, and the punch has a groove that matches the protrusion; the through hole passes through the protrusion and faces the abutment block.

[0013] By adopting the above technical solution, the material strip is cut by using the protrusion on the limiting block and the groove on the punch that matches the protrusion. The through hole passes through the protrusion, and the material strip passes through the through hole and out of the protrusion, so that the cut of the material strip is arc-shaped, which reduces the sharpness of the material strip and reduces the possibility of accidental injury during use.

[0014] Preferably, there are several forming columns, all of which are disposed below the material strip, and there is a gap between the forming columns and the top bend, with at least a portion of the forming columns in contact with the material strip.

[0015] By adopting the above technical solution, multiple forming columns set below the material strip are used to bend and shape different parts of the material strip to different degrees, and at least a part of the forming column is in contact with the material strip, supporting the material strip during feeding and facilitating the punch to complete the stamping action; there is a gap between the forming column and the top bend to prevent the blade from colliding and causing damage to the forming column and the top bend.

[0016] Preferably, it further includes a push rod; the push rod is used to push out the finished product, the push rod is telescopically disposed between the forming column and the punch, and the axis of the push rod is parallel to the axis of the forming column.

[0017] By adopting the above technical solution, a push rod is set between the forming column and the punch, and the axis of the push rod is parallel to the axis of the forming column. After the punch presses the strip into shape, the retractable push rod extends to push out the finished part, eliminating the need for manual unloading and further improving production efficiency. When the punch is pressing the strip, the push rod is in a retracted state, which does not affect the up-and-down movement of the punch to press the strip.

[0018] Preferably, a bending drive is provided on the side of the top bend head away from the punch, and the bending drive is used to drive the top bend head to bend the strip.

[0019] By adopting the above technical solution, the bending head is moved by the bending drive component to bend the strip and shape it into the required shape.

[0020] Preferably, the feeding drive is used to drive the material strip through the through hole and abut against the abutting block, and the feeding drive is disposed on the side of the punch away from the abutting block.

[0021] By adopting the above technical solution, the feeding drive is used to feed the strip from the straightening mechanism, and the straightened strip is fed into the through hole and then into the forming mechanism, so that one end of the strip abuts against the abutting block, and the punch is used for stamping and forming. The feeding drive is set on the side of the punch away from the abutting block, which can both pull the strip out of the straightening mechanism and feed the strip into the forming mechanism, reducing the number of drive components and saving costs.

[0022] Preferably, a stamping drive is provided at the end of the punch away from the strip, and the output end of the stamping drive is connected to the punch.

[0023] By adopting the above technical solution, the punch is driven to move up and down to punch the strip material using a stamping drive component. The stamping drive component is located at the end of the punch that is away from the strip material, so that the punch punches from top to bottom during the stamping process.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating the straightening and forming mechanisms into one machine, the entire process can be automated without manual intervention, greatly improving production efficiency; 2. An abutment block is set on one side of the punch so that the end face of the material strip after feeding abuts against the abutment block, which limits the length of the material strip that the punch can punch, and prevents the problem of the stamped product being unqualified due to the material strip being too long or too short, thereby increasing the finished product qualification rate to a certain extent. 3. The stamped finished product is pushed out using the push rod, which facilitates the next stamping process and eliminates the need for manual unloading, further improving production efficiency.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a belt buckle pin production equipment.

[0029] Reference Figure 1 A belt buckle pin production equipment includes a material belt 1, a feeding tray 2, a straightening mechanism 3, a forming mechanism 4, a bending drive 5, a feeding drive 6, a stamping drive 7, and a housing 8. One end of the material belt 1 is wound around the feeding tray 2, which can rotate around an axis. The other end of the material belt 1 is straightened by the straightening mechanism 3 and then enters the forming mechanism 4. The housing 8 is located on one side of the feeding tray 2. Both the straightening mechanism 3 and the forming mechanism 4 are located on the housing 8. The straightening mechanism 3 is located on the side of the housing 8 closer to the feeding tray 2, and the forming mechanism 4 is located on the side of the straightening mechanism 3 away from the feeding tray 2.

[0030] Reference Figure 2 The straightening mechanism 3 includes multiple first pressure rollers 31 and second pressure rollers 32, and both the first pressure rollers 31 and the second pressure rollers 32 are arranged on both sides of the material belt 1. The first pressure rollers 31 are used to straighten the material belt 1 in the horizontal direction, and the second pressure rollers 32 are used to straighten the material belt 1 in the vertical direction. The first pressure rollers 31 and the second pressure rollers 32 are placed side by side along the axial direction of the material belt 1. There are multiple first pressure rollers 31, which are staggered on both sides of the material belt 1 in the horizontal direction; there are also multiple second pressure rollers 32, which are staggered on both sides of the material belt 1 in the vertical direction.

[0031] Reference Figure 2 The first pressure roller 31 is mounted on the horizontal mounting platform 91, and the second pressure roller 32 is mounted on the vertical mounting platform 92. The horizontal mounting platform 91 and the vertical mounting platform 92 are fixed to the housing 8 by a bracket.

[0032] In this embodiment, there are five first pressure rollers 31 and five second pressure rollers 32. All five first pressure rollers 31 are disposed on the horizontal mounting platform 91, with two located on the same side of the material belt 1 and the remaining three located on the other side of the material belt 1. The spacing between the first pressure rollers 31 located on the same side of the material belt 1 is equal, and the distance between the axes of two adjacent first pressure rollers 31 located on the same side of the material belt 1 is greater than the diameter of the first pressure roller 31. The distance between the projections of the axes of two adjacent first pressure rollers 31 located on both sides of the material belt 1 is greater than the radius of the first pressure roller 31 and less than the diameter of the first pressure roller 31. Five second pressure rollers 32 are all mounted on the vertical mounting platform 92, with two second pressure rollers 32 located on the same side of the material belt 1 and the remaining three second pressure rollers 32 located on the other side of the material belt 1. The spacing between the second pressure rollers 32 located on the same side of the material belt 1 is equal, and the distance between the axes of two adjacent second pressure rollers 32 located on the same side of the material belt 1 is greater than the diameter of the second pressure roller 32. The distance between the projections of the axes of two adjacent second pressure rollers 32 located on both sides of the material belt 1 on the material belt 1 is greater than the radius of the second pressure roller 32 and less than the diameter of the second pressure roller 32.

[0033] Reference Figure 2 The forming mechanism 4 includes a punch 41, a top bend 42, a limiting block 45, and an abutment block 44. The abutment block 44 abuts against one end of the material strip 1. The punch 41 is positioned above the material strip 1, and there is a certain distance between the punch 41 and the material strip 1 when no punching is being performed.

[0034] Reference Figure 2 The housing 8 is also provided with a feeding drive 6, which is located between the straightening mechanism 3 and the forming mechanism 4. The feeding drive 6 includes two feeding pressure rollers 61, which are symmetrically arranged on both sides of the vertical of the material strip 1 and clamp the material strip 1. The feeding drive 6 performs intermittent movement, intermittently pulling the material strip 1 out of the straightening mechanism 3 and then feeding it into the forming mechanism 4. The housing 8 is provided with an intermittent drive mechanism (not shown in the figure) that drives the feeding pressure rollers 61 to rotate intermittently. This intermittent drive mechanism can select a ratchet mechanism, an incomplete gear mechanism, or other mechanisms to drive the feeding pressure rollers to rotate intermittently.

[0035] Reference Figure 3 The forming mechanism 4 also includes a forming column 43, which is disposed under the material strip 1 and at least a portion of the forming column 43 is in contact with the material strip 1. The forming column 43 not only acts as a mold during stamping, but also provides a certain support during feeding.

[0036] Reference Figure 4 The housing 8 is equipped with a stamping drive 7 and a bending drive 5. The output end of the stamping drive 7 is connected to the punch 41, and the bending drive 5 is connected to the bending head 42. In this embodiment, the stamping drive 7 is a hydraulic cylinder that drives the punch 41 to move up and down and stamp the strip 1. Since the area to be stamped on the strip 1 in this application is small and the thickness is also thin, it is not necessary to cut the strip 1 with a large punching force. The bending drive 5 and the bending head 42 are a crank-slider mechanism. The bending head 42 is the output end, that is, the bending head 42 is a slider. Under the driving action of the bending drive 5, it slides back and forth continuously to complete the bending action. In other embodiments of this application, the bending drive 5 can be replaced with a hydraulic cylinder to reduce energy loss.

[0037] Reference Figure 5 The forming mechanism 4 further includes a limiting block 45 and a push rod 46. The limiting block 45 is disposed on the side of the punch 41 away from the abutment block 44. The limiting block 45 is provided with a protrusion 451 on the side of the punch 41 close to the punch 41. The punch 41 is provided with a groove 402 matching the protrusion 451 on the side of the limiting block 45 close to the limiting block 45. The limiting block 45 has a through hole 401 at the position corresponding to the material strip 1. The through hole 401 passes through the protrusion 451, and the material strip 1 passes through the through hole 401 and abuts against the abutment block 44. The push rod 46 is telescopically disposed within the housing 8. The push rod 46 is used to push out the stamped belt buckle pin, thereby facilitating the next stamping. When the push rod 46 is extended, at least a portion of it contacts the material strip 1, and the axial length of the material strip 1 when extended is greater than the axial length of the forming column 43. When the material strip 1 is retracted, the end face of the push rod 46 near the punch 41 is at least flush with the end face of the housing 8, or retracts into the housing 8. There is a gap between the push rod 46 and the punch 41 to prevent blade collision.

[0038] Reference Figure 3 There is a gap between the top bend 42 and the forming column 43. The top bend 42 is used to bend the strip 1 under the strip 1. After the punch 41 cuts the strip 1 and presses it downward to a certain extent, the top bend 42 is used to press and bend the strip 1 below, so that the strip 1 forms a semi-closed open ring. The stamping is completed, and the specific shape of the product is as follows. Figure 6 As shown.

[0039] Reference Figure 3One end of the material strip 1 abuts against the abutting block 44. There is a small gap between the abutting block 44 and the punch 41. There is also a small gap between the limiting block 45 and the punch 41, which is used to reduce friction when the punch 41 is pressed down.

[0040] Reference Figure 5 The protrusion 451 and the groove 402 work together to cut the material strip 1 when the punch 41 is pressed down. When the material strip 1 abuts against the abutting block 44, at least a portion of the forming column 43 contacts the material strip 1 and supports the material strip 1.

[0041] In this embodiment, there are two forming columns 43, which are set according to the forming shape of the strip 1; in other embodiments of this application, the number and position of the forming columns 43 can be adjusted according to actual needs.

[0042] Reference Figure 1 and Figure 2 The feeding drive 6 drives the material belt 1 to feed intermittently. There is sufficient friction between the feeding drive 6 and the material belt 1 so that the material belt 1 is fed when the feeding drive 6 rotates. The distance between the axes of the two feeding pressure rollers 61 is equal to or slightly less than the sum of the thickness of the feeding pressure rollers 61 and the material belt 1, thereby ensuring that the material belt 1 is also moved when the feeding drive 6 rotates, preventing slippage.

[0043] Reference Figure 2 Limiting blocks 10 are provided on both sides of the end of the punch 41 near the stamping drive 7. The two limiting blocks 10 are symmetrically arranged about the punch 41. The limiting blocks 10 are used to restrict the punch 41 during stamping to prevent the punch 41 from shaking when it is pressed down, which would result in poor stamping effect or even collision. The distance between the limiting block 10 and the abutment block 44 is less than the height of the punch 41. In this case, the punch 41 enters between the limiting block 45 and the abutment block 44 before it is completely separated from the limiting block 10.

[0044] Reference Figure 5 It also includes a support plate 11, which is disposed at the sliding bottom of the top bend head 42, and the top bend drive member 5 slides on the support plate 11 under the action of the top bend drive member 5.

[0045] In this embodiment, since the top bending drive 5 is a crank-slider mechanism, the crank rotates continuously around the axis. Therefore, to ensure safety, the time for the crank to rotate around the axis once is equal to the time for the punch 41 to press down twice consecutively. When the crank pushes the top bending head 42 to bend, the punch 41 is in a pressing state. Similarly, the feeding drive 6 rotates intermittently, and the time for the feeding drive 6 to stop is equal to the time for the punch 41 to press down and then fully lift up during a single punch.

[0046] In this embodiment, for ease of illustration, the strip 1 in the accompanying drawings is shown as a long cylindrical shape. In other embodiments of this application, the strip 1 can be a long rectangular strip with a smaller thickness and narrower width.

[0047] The implementation principle of a belt buckle pin production equipment according to an embodiment of this application is as follows: the material belt 1 is passed through multiple first pressure rollers 31, multiple second pressure rollers 32 and the feeding drive member 6 respectively, and the material belt 1 is inserted into the through hole 401 in the limiting block 45 and abuts against the abutting block 44; during stamping, the punch 41 presses down, the punch 41 completely cuts the material belt 1, and the forming column 43 is used for forming. After the punch 41 cuts the material belt 1, the top bend 42 is... Under the action of the bending drive 5, the material strip 1 is bent, and then the punch 41 retracts. The bending head 42 also slides back under the action of the bending drive 5. The push rod 46 extends out from the housing 8 and pushes down the formed belt buckle pin, so that the stamped belt buckle pin is separated from the forming post 43. Then the push rod 46 retracts into the housing 8. The feeding drive 6 drives the material strip 1 to feed, so that the material strip 1 abuts against the abutment block 44 again. Then the punch 41 performs the next stamping.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
