Description

Technical Field

[0001] The present application relates to the field of stamping technology, and in particular to a seamless stamping device for a garage door edging bracket. Background Art

[0002] When the stamping die is stamping a workpiece, if the friction between the punch and the workpiece is large, the surface of the workpiece will easily be scratched by the punch and leave marks.

[0003] In this regard, China's patent application number CN202123179062.8 discloses a markless metal stamping die. This solution mainly arranges sponge rings on both sides of the punch to apply lubricating oil to the outer surface of the punch to reduce the friction between the punch and the product, thereby reducing scratches.

[0004] However, in the process of implementing the technical solution in the embodiments of the present application, the inventor of the present application found that the above technology has at least the following technical problems:

[0005] 1. The sponge ring will have a better effect if it is set around a relatively round punch. However, for a relatively long workpiece such as a garage door edging bracket, a longer punch is required, and the sponge ring is difficult to fix;

[0006] 2. For relatively long workpieces such as garage door edging brackets, conventional stamping methods have fewer force points, which can easily lead to inconsistent force at both ends of the workpiece, affecting the stamping effect. Utility Model Content

[0007] In order to make up for the above shortcomings, the present application provides a garage door edging bracket seamless stamping device, which aims to improve the problems mentioned in the above background technology.

[0008] An embodiment of the present application provides a seamless stamping device for a garage door edging bracket, comprising a frame, a pressure plate and a push plate, wherein the pressure plate is vertically slidably connected to the frame, and the push plate is laterally slidably connected to the frame, the frame and the pressure plate are respectively provided with a concave mold and a convex mold, the pressure plate is hinged with support rods in an array, all of the support rods are hinged with the push plate, and the push plate is dynamically connected with a reciprocating member.

[0009] In a specific implementation manner, the frame includes a square frame, a polished rod is fixedly connected inside the square frame, and the pressure plate is slidably connected to the polished rod.

[0010] In the above implementation process, the light rod is vertically arranged to guide the vertical movement of the pressing plate and to carry the punch to form a stamping action.

[0011] In a specific embodiment, the frame further includes a slot frame, the slot frame is fixedly connected to the square frame, and the push plate is slidably connected to the slot frame.

[0012] In the above implementation process, the slot frame is horizontally arranged to guide the push plate to move horizontally, and a plurality of support rods are used to push the pressure plate to move vertically to achieve a uniform force effect.

[0013] In a specific embodiment, the reciprocating member includes a connecting rod and an eccentric wheel, two ends of the connecting rod are respectively hinged to the eccentric wheel and the push plate, and the eccentric wheel is rotatably connected to the frame.

[0014] In a specific embodiment, the reciprocating member further includes a motor, the motor is mounted on the frame, and the output end of the motor is connected to the eccentric wheel shaft.

[0015] In the above implementation process, the motor drives the eccentric wheel to rotate, and drives the push plate to reciprocate horizontally through the connecting rod, thereby generating a stamping action.

[0016] In a specific embodiment, the mouth of the die is rotatably connected to a guide roller.

[0017] In the above implementation process, the guide roller converts the sliding friction between the workpiece and the die into rolling friction, thereby reducing scratches during the stamping process.

[0018] In a specific embodiment, a support wheel is rollingly connected to the inner side of the guide roller, and the support wheel is rotationally connected to the die.

[0019] In the above implementation process, since the guide roller is very long and is supported only at two ends, a plurality of support wheels are arranged along the axial direction of the guide roller to reduce deformation and displacement of the guide roller during the stamping process.

[0020] In a specific implementation manner, the die is divided into a movable part and a fixed part, the movable part is connected to the frame in a transverse sliding manner, and a hydraulic cylinder is provided between the movable part and the frame.

[0021] In the above implementation process, during stamping, the hydraulic cylinder presses the movable part against the fixed part to form a complete concave mold. When the stamping is completed, the hydraulic cylinder retracts and the movable part leaves the fixed part to facilitate the extraction of the edging bracket. In this embodiment, the movable part is connected to the dovetail groove of the square frame in a sliding manner.

[0022] Compared with the prior art, the beneficial effects of the present application are: the horizontally moving push plate pushes the pressure plate to move vertically through the array of support rods, thereby achieving a multi-point force effect, which is beneficial to uniform force on the mold and the workpiece, reducing scratches on the workpiece during squeezing in through guide rollers, and achieving scratches on the workpiece during demolding through a detachable die.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0030] See also Figure 1-Figure 4 The present application provides a garage door edging bracket seamless punching device, including a frame 10, a pressing plate 20 and a push plate 30, wherein the pressing plate 20 is vertically slidably connected to the frame 10, and the push plate 30 is horizontally slidably connected to the frame 10, and a concave mold 40 and a convex mold 50 are respectively arranged on the frame 10 and the pressing plate 20, and a support rod 60 is hingedly arranged on the pressing plate 20, and all the support rods 60 are hingedly connected to the push plate 30, and a reciprocating member 70 is dynamically connected to the push plate 30. Among them, the horizontally moving push plate 30 pushes the pressing plate 20 to move vertically through the support rods 60 of the array, so as to achieve the effect of multi-point force generation, which is conducive to uniform force on the mold and the workpiece.

[0031] See also Figure 1-Figure 4 The frame 10 includes a square frame 11, a polished rod 12 is fixedly connected in the square frame 11, and a pressing plate 20 is slidably connected to the polished rod 12. The polished rod 12 is vertically arranged to guide the pressing plate 20 to move vertically and form a stamping action with the punch 50.

[0032] See also Figure 1-Figure 4 The frame 10 further includes a slot frame 13, which is fixedly connected to the frame 11, and the push plate 30 is slidably connected to the slot frame 13. The slot frame 13 is horizontally arranged to guide the push plate 30 to move horizontally, and to push the pressing plate 20 to move vertically through a plurality of support rods 60 to achieve a uniform force effect.

[0033] See also Figure 1-Figure 4 The reciprocating member 70 includes a connecting rod 71 and an eccentric wheel 72. The two ends of the connecting rod 71 are respectively hinged with the eccentric wheel 72 and the push plate 30. The eccentric wheel 72 is rotatably connected to the frame 11. The reciprocating member 70 also includes a motor 73. The motor 73 is mounted on the frame 11. The output end of the motor 73 is connected to the shaft of the eccentric wheel 72. The motor 73 drives the eccentric wheel 72 to rotate, and drives the push plate 30 to reciprocate horizontally through the connecting rod 71, thereby generating a stamping action.

[0034] See also Figure 1-Figure 4 The mouth of the die 40 is rotatably connected with a guide roller 44. The guide roller 44 converts the sliding friction between the workpiece and the die 40 into rolling friction, thereby reducing scratches during the stamping process.

[0035] See also Figure 1-Figure 4 A support wheel 45 is rollingly connected to the inner side of the guide roller 44, and the support wheel 45 is rotatably connected to the die 40. Since the guide roller 44 is very long and only supported at both ends, a plurality of support wheels 45 are arranged along the axial direction of the guide roller 44 to reduce the deformation and displacement of the guide roller 44 during the stamping process.

[0036] See also Figure 1-Figure 4 The die 40 is divided into a movable part 41 and a fixed part 42. The movable part 41 is connected to the frame 11 in a transverse sliding manner. A hydraulic cylinder 43 is provided between the movable part 41 and the frame 11. During stamping, the hydraulic cylinder 43 presses the movable part 41 against the fixed part 42 to form a complete die 40. When the stamping is completed, the hydraulic cylinder 43 retracts, and the movable part 41 leaves the fixed part 42, which facilitates the extraction of the hemming bracket. In this embodiment, the movable part 41 is connected to the frame 11 in a dovetail groove-type sliding manner.

[0037] The working principle of the seamless stamping device for the garage door edging bracket is as follows: during stamping, the motor 73 drives the eccentric wheel 72 to rotate, and drives the push plate 30 to move horizontally through the connecting rod 71, and pushes the pressure plate 20 to move downward along the light rod 12 through multiple support rods 60 to realize the stamping action of the punch 50. When the workpiece is squeezed into the die 40, the two sides roll with the guide rollers 44, which reduces friction, is beneficial to stamping and reduces scratches. When the stamping is completed, the hydraulic cylinder 43 retracts, and the movable part 41 leaves the fixed part 42, which is convenient for the edging bracket to be pulled out, further reducing scratches during demolding. In summary, the horizontally moving push plate 30 pushes the pressure plate 20 to move vertically through the array of support rods 60, achieving a multi-point force effect, which is beneficial to uniform force on the mold and the workpiece, and reduces scratches when the workpiece is squeezed in through the guide rollers 44, and achieves scratches when the workpiece is demolded through the detachable die 40.
