Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a slider-type punching and shearing structure. Background Technology

[0002] In the existing technology, when the profile arm is too high, the material strip floats up, causing the profile to be slightly uneven and have positioning errors. The punch is prone to interfering with the left and right end faces of the profile arm that have been side-cut. Therefore, a relatively large step is usually left to avoid interference between the punch and the two end faces, and then the front side is punched and sheared. However, the problem is that the step on the arm after punching will affect the product size and appearance. Therefore, this method is not suitable for products with high size requirements.

[0003] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0031] The features and performance of this utility model will be further described in detail below with reference to the embodiments. Example

[0032] like Figure 1-4 This application discloses a slider-type punching and shearing structure, comprising an upper die 100 and a lower die 200.

[0033] The upper mold 100 includes, from top to bottom, an upper mold base 101, an upper pad 102, an upper clamping plate 103, and a stripper plate 104. A first spring 105 is provided between the upper mold base 101 and the stripper plate 104. A punch fixing base 106 is mounted on the upper clamping plate 103. A punch 107 is mounted on the side of the punch fixing base 106 facing the lower mold 200. Punch sliders 108 that cooperate with the punch 107 are provided on both sides of the punch 107. A first driving inclined surface 1071 is provided on both sides of the punch 107. The punch slider 108 is provided with a function that interacts with the first driving inclined surface. The second driving inclined surface 1081 cooperates with 1071. Each of the punches 107 sliders is connected to a second spring 110 mounted on the upper clamping plate 103 via an ejector pin 109. The punches 107 and the two punch sliders 108 can pass through the stripper plate 104 and extend out of the stripper plate 104. The lower die 200 is provided with a cutting edge scrap shear 207 that cooperates with the punches 107 and the two punch sliders 108. Through the above structural design, the scrap of the product can be punched and sheared without interference between the punch and the side end face of the profile arm, and steps on the side end face of the profile arm can be prevented from affecting the product size and aesthetics.

[0034] When this invention is in operation, the upper die descends, and the punch slider is pushed downwards under the action of the first spring and the ejector pin, causing both punch sliders to retract towards the punch. This ensures that after the two punch sliders are pushed out, a 1mm gap remains between them and the side end face of the profile arm, preventing interference between the punch and the side end face of the profile arm and ensuring smooth mold closure. The upper die continues to descend, and the two punch sliders move left and right respectively under the action of the punch, aligning with the edge of the cutting waste and entering the punching and shearing process. The upper die continues to descend, and the two punch sliders cut the waste. After cutting the waste, the two punch sliders push the waste downwards under the action of the first spring and the ejector pin, and the two punch sliders retract towards the punch, thus entering the next motion cycle.

[0035] Specifically, an equalizing screw 111 is movably mounted on the upper mold base 101, the upper pad 102, and the upper clamping plate 103. The threaded end of the equalizing screw 111 is fixedly connected to the stripper plate 104. The height difference when the mold is opened and closed is controlled by the equalizing screw, which can effectively avoid collisions or friction between mold components caused by non-parallelism or misalignment of the mold plates, and reduce wear and damage to the mold.

[0036] Specifically, the lower mold 200 includes a lower template 201, a lower pad 202, a lower mold base 203, and a lower support plate 204 arranged sequentially from top to bottom. A plurality of lower pads 205 are provided between the lower mold base 203 and the lower support plate 204. A lower mold shearing opening 206 is provided on the lower template 201. The lower mold shearing opening 206 is provided with a cutting waste shearing opening 207. The diameter of the cutting waste shearing opening 207 gradually increases from top to bottom, thereby facilitating the falling of waste.

[0037] Specifically, the upper clamping plate 103 is provided with a spring seat 112, a third spring 113 is installed on the spring seat 112, and a movable positioning pin 114 is connected to the third spring 113. The lower template 201, the lower pad 202 and the lower mold base 203 are provided with blind holes that cooperate with the movable positioning pin 114. The positioning of the profile during processing is achieved by the cooperation between the movable positioning pin 114 and the blind holes.

[0038] Specifically, the upper pad 102 is provided with a plurality of inner guide pillars 115, and the lower pad 202 is provided with a plurality of inner guide sleeves 208, with each of the inner guide pillars 115 corresponding to one of the inner guide sleeves 208; the upper mold base 101 is provided with a plurality of outer guide pillars 116, and the lower mold base 203 is provided with a plurality of outer guide sleeves 209, with each of the outer guide pillars 116 corresponding to one of the outer guide sleeves 209; through the cooperation of the inner guide pillars and inner guide sleeves, as well as the outer guide pillars and outer guide sleeves, the opening and closing actions of the upper and lower molds are precisely guided during the closing process, so that the upper and lower molds are precisely aligned and the high-precision fit of the molds is maintained.

[0039] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, stable product quality, and good consistency.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
