DETAILED DESCRIPTION

[0029] In order to make the skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings.

[0030] As shown in Figures 1-7 , the bending and stamping integrated device provided in the embodiment of the present application comprises a support 1 and a punch 2 and a recess 3 arranged on the support 1 for bending a plate material 12, the punch 2 can move towards the recess 3 by the driving of a first driving member 9, two positioning rods 5 are arranged oppositely and simultaneously slide against the left side surface of the plate material 12 and are elastically arranged on the support 1, a protruding part of the punch 2 is located between the two positioning rods 5 and abuts against the right side surface of the plate material 12 so that the plate material 12 is pressed and positioned between the punch 2 and the positioning rods 5;

[0031] The bending position of the plate 12 is in abutment with the protruding portion of the punch 2, and the punch 2 drives the plate 12 to move synchronously in the process of moving towards the die 3, so that the plate 12 is bent in the state of abutment with the protruding portion of the punch 2 at the bending position of the plate 12.

[0032] The bending and punching integrated device provided by the embodiment is used for sequentially bending and punching a metal plate. The terms related to directions and positions in the embodiment are relative to the drawings. Specifically, the punch 2 and the die 3 are oppositely arranged, the side of the punch 2 facing the die 3 is a protruding portion, the side of the die 3 facing the punch 2 is an inner recess portion matched with the protruding portion, and the plate 12 is located between the punch 2 and the die 3. When the punch 2 and the die 3 are relatively close, the plate 12 can be bent. The protruding portion of the punch 2 has two inclined sides, and the two sides of the plate 12 are respectively in abutment with the two inclined sides of the protruding portion of the punch 2 when the plate 12 is bent. The first driving member 9 is a pneumatic cylinder or a hydraulic cylinder, the output end of the first driving member 9 is fixedly connected with the punch 2, and the punch 2 can be driven to move towards the die 3 and move away from the die 3 by starting the first driving member 9. The die 3 is fixedly installed on the support 1, and the plate 12 can be bent when the punch 2 moves towards the die 3. After the bending is completed, the punch 2 moves away from the die 3. The two positioning rods 5 are elastically and slidably connected with the support 1, so that the two positioning rods 5 have elastic tension. The two positioning rods 5 are respectively located on the front and back sides of the left side of the plate 12 and are in abutment with the left side of the plate 12, and the protruding portion of the punch 2 is located between the two positioning rods 5 and is in abutment with the right side of the plate 12. Under the action of the elastic tension of the two positioning rods 5, the plate 12 is pressed and positioned between the protruding portion of the punch 2 and the positioning rods 5. When the punch 2 is driven by the first driving member 9 to move towards the die 3, the plate 12 can be driven to move synchronously. Therefore, as long as the position of the plate 12 to be bent is in abutment with the protruding portion of the punch 2, the plate 12 can be accurately bent at the position to be bent. In work, the two positioning rods 5 are first pulled away from the punch 2, so that the plate 12 can be inserted between the protruding portion of the punch 2 and the positioning rods 5. The position of the plate 12 is adjusted, so that the position of the plate 12 to be bent is in abutment with the protruding portion of the punch 2. The plate 12 is pressed and fixed on the punch 2 under the action of the tension of the two positioning rods 5. Then, the first driving member 9 is started to drive the punch 2 to move towards the die 3 together with the plate 12, so that the plate 12 is deformed under pressure, until the plate 12 is bent. Since the bending position of the plate 12 is in abutment with the protruding portion of the punch 2, the bending position of the plate 12 is not easy to deviate when the plate 12 is bent, and accurate bending is achieved. In the prior art, when the plate is placed between the punch and the die, the plate cannot be positioned, so that the bending position of the plate cannot be accurately matched with the protruding portion of the punch, and the bending position is easy to deviate when bent.

[0033] In the embodiment, the two positioning rods 5 are elastically slidably arranged on the support 1, and the convex part of the convex die 2 is located between the two positioning rods 5, so that when the plate 12 is placed between the convex part of the convex die 2 and the positioning rods 5, the plate 12 can be pressed and positioned between the convex die 2 and the positioning rods 5 under the action of the elasticity, and the positioned plate 12 can move synchronously with the convex die 2, and when the bending part of the plate 12 abuts against the convex part of the convex die 2, the plate 12 can be accurately bent at the bending position when the convex die 2 and the concave die 3 press the plate 12, and the bending position offset of the plate 12 is not prone to occur. Therefore, compared with the prior art, the plate 12 can be positioned on the convex part of the convex die 2 by the elastic sliding of the two positioning rods 5 before bending, and as long as the bending position of the plate 12 corresponds to the convex part of the convex die 2, the plate 12 can be bent at the required position during bending, and the bending position offset of the plate 12 is not prone to occur, thereby effectively solving the problems in the prior art.

[0034] In the embodiment, the two positioning rods 5 are elastically slidably arranged on the support 1, and the convex part of the convex die 2 is located between the two positioning rods 5, so that when the plate 12 is placed between the convex part of the convex die 2 and the positioning rods 5, the plate 12 can be pressed and positioned between the convex die 2 and the positioning rods 5 under the action of the elasticity, and the positioned plate 12 can move synchronously with the convex die 2, and when the bending part of the plate 12 abuts against the convex part of the convex die 2, the plate 12 can be accurately bent at the bending position when the convex die 2 and the concave die 3 press the plate 12, and the bending position offset of the plate 12 is not prone to occur. Therefore, compared with the prior art, the plate 12 can be positioned on the convex part of the convex die 2 by the elastic sliding of the two positioning rods 5 before bending, and as long as the bending position of the plate 12 corresponds to the convex part of the convex die 2, the plate 12 can be bent at the required position during bending, and the bending position offset of the plate 12 is not prone to occur, thereby effectively solving the problems in the prior art.

[0035] Further, the two L-shaped plates 4 corresponding to the two positioning rods 5 are fixedly arranged on the support 1, the opposite surfaces of the L-shaped plates 4 and the support 1 are each provided with a slide 8, the top of the positioning rod 5 is slidably arranged in the slide 8 on the L-shaped plate 4, the bottom of the positioning rod 5 is slidably arranged in the slide 8 on the support 1, the slide 8 is used for providing a guiding action for the positioning rod 5, so that the positioning rod 5 can only slide left and right and cannot move up and down, so that the two positioning rods 5 can provide a stable fixing action for the plate 12. When the plate 12 is finished processing, the first driving member 9 drives the convex die 2 to move away from the concave die 3 to drive the two positioning rods 5 to gradually slide to the right side of the slide 8, and when the two positioning rods 5 abut against the right side of each slide 8 (the right side of each slide 8 is located in the same vertical plane), the two positioning rods 5 stop sliding, at this time, the slide 8 plays a role of limiting the positioning rod 5, and as the convex die 2 continues to move, the distance between the convex part of the convex die 2 and the two positioning rods 5 gradually increases, so that the plate 12 is released from positioning, at this time, the plate 12 can be taken out from between the convex die 2 and the positioning rods 5 to realize discharging.

[0036] The top and bottom of the positioning rod 5 are both sliding blocks 501, the opposite sides of the two sliding blocks 501 are respectively embedded with a ball 502, and the two balls 502 are in abutment with the corresponding sliding grooves 8 to reduce the sliding friction of the positioning rod 5. The part of the positioning rod 5 between the two sliding blocks 501 is a cylinder, and the part of the positioning rod 5 in abutment with the plate 12 is a cylinder, so that the relative sliding between the two positioning rods 5 and the plate 12 during the deformation of the plate 12 during bending reduces the sliding friction, thereby reducing the wear of the plate 12.

[0037] In the embodiment, the convex die 2 and the concave die 3 pull the two positioning rods 5 to slide during the extrusion of the plate 12 for bending, so that the two positioning rods 5 respectively extrude the two sides of the plate 12 until the two positioning rods 5 respectively extrude the two sides of the plate 12 and are attached to the two inclined surfaces of the convex die 2 to fix the two sides of the plate 12 when the plate 12 is bent. That is, when the plate 12 is bent, the tension spring 6 is still in a stretched state, so that the two positioning rods 5 are still extruded to the two sides of the plate 12 under the elastic force of the tension spring 6, thereby stably attaching the two sides of the plate 12 to the two inclined surfaces of the convex die 2, fixing the two sides of the plate 12, thereby improving the stability and firmness of the plate 12, and improving the punching quality of the plate 12. In the prior art, the plate can only be fixed by extruding the plate with the convex die and the concave die, and the two sides of the plate cannot be fixed, which can easily cause the two sides of the plate to shake when the plate is punched, thereby the punching quality cannot be effectively guaranteed. Therefore, the two positioning rods 5 not only have the effect of positioning the plate 12 during bending to prevent the bending position of the plate 12 from deviating, but also have the effect of fixing the two sides of the plate 12 during punching to prevent the plate 12 from shaking during punching, thereby improving the punching quality.

[0038] In the embodiment, the inclined surface of the protruding part of the punch 2 is provided with a punching hole 201, the number and position of the punching hole 201 are set according to actual needs, the punching hole 201 is located on one of the inclined surfaces of the protruding part of the punch 2 or on both of the inclined surfaces of the protruding part of the punch 2, and the plate 12 covers the punching hole 201 when the plate 12 is bent. At this time, the protruding part of the punch 2 plays a role in supporting the plate 12, so that the plate 12 will not be deformed when punching. The support 1 is provided with a punching rod 11 corresponding to the punching hole 201 through a second driving element 10. The second driving element 10 is a pneumatic cylinder or a hydraulic cylinder, and is fixedly installed on the support 1. The punching rod 11 is fixedly installed on the output end of the second driving element 10 and can move towards the punching hole 201 and away from the punching hole 201 under the action of the second driving element 10. The punching rod 11 is perpendicular to the inclined surface of the protruding part of the punch 2. When both of the inclined surfaces of the protruding part of the punch 2 are provided with the punching hole 201, two second driving elements 10 are needed. When the plate 12 is bent, the punching hole 201 is located on the axis of the punching rod 11, so that after the plate 12 is bent, the second driving element 10 drives the punching rod 11 to move towards the punching hole 201 to punch the bent plate 12.

[0039] In the embodiment, the inside of the punch 2 is provided with a cavity communicating with the punching hole 201. The waste and debris generated when the plate 12 is punched are pushed into the cavity of the punch 2 by the punching rod 11, preventing the waste and debris generated during the punching process from scattering outside, so as to facilitate the collection of the waste and debris. Thus, the punch 2 also plays a role in collecting the waste and debris generated during punching.

[0040] Further, the bottom of the punch 2 is in sliding fit with the top surface of the support 1, the bottom of the punch 2 is provided with an open hole 202, and the support 1 is provided with a leakage hole 102 matched with the open hole 202. The open hole 202 and the leakage hole 102 are staggered when the punching rod 11 punches the plate 12, at which time the waste and debris entering the cavity of the punch 2 are concentrated in the cavity of the punch 2 to achieve concentrated collection. After punching, the open hole 202 gradually coincides with the leakage hole 102 during the sliding process of the punch 2 away from the concave die 3, so that the waste and debris in the cavity of the punch 2 are scraped into the leakage hole 102 by the punch 2, and then collected in a specific position, thereby automatically realizing the cleaning of the waste and debris in the cavity of the punch 2.

[0041] Further, the bracket 1 is fixedly embedded with a filter screen 7 between the concave die 3 and the leakage hole 102, the top and bottom of the filter screen 7 are exposed, the top of the filter screen 7 is in the same plane with the top of the bracket 1 so that the bottom of the convex die 2 is in sliding fit with the top surface of the filter screen 7, the filter screen 7 is used for filtering the waste and the debris, the debris with small volume can pass through the filter screen 7, the waste with large volume cannot pass through the filter screen 7, when the punching rod 11 punches the plate 12, the open hole 202 coincides with the leakage hole 102 so that the debris in the cavity of the convex die 2 passes through the filter screen 7 and the waste is left on the top of the filter screen 7, because the waste is left on the top of the filter screen 7, when the convex die 2 moves away from the concave die 3, the convex die 2 can push the waste from the filter screen 7 until the waste is sent into the leakage hole 102 and discharged, and the debris is discharged through the filter screen 7, so that the discharge directions of the debris and the waste are different, thereby realizing the separation of the debris and the waste. Therefore, the waste and the debris can be separated and recycled during the movement of the convex die 2 away from the concave die 3 to release the positioning of the plate 12 by the positioning rod 5 and the convex die 2.

[0042] The bottom of the bracket 1 is fixedly installed with a track plate 15, the track plate 15 is slidably inserted with a debris collection box 13 and a waste collection box 14, the debris collection box 13 covers the filter screen 7 so that the debris passing through the filter screen 7 enters the debris collection box 13, the waste collection box 14 covers the leakage hole 102 so that the waste entering the leakage hole 102 falls into the waste collection box 14, thereby separating the collection of the waste and the debris, and the subsequent operation of separating the waste and the debris is omitted.

[0043] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
