Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1:

[0021] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the front frame connecting to the crossbeam punching die. Figure 2 This is a structural schematic diagram of the fixed tool holder 107. Figure 3 This is a cross-sectional view of the protective cover 103. This utility model provides a front-end frame connecting beam punching die: it includes a base 101, a guide and limiting mechanism 102, and an auxiliary mechanism. The auxiliary mechanism includes a protective cover 103, a mounting plate 104, a first driving component 105, a punching cutter 106, a fixed cutter holder 107, a limiting block 108, a pressure plate 109, a descending device, and a guiding device. The descending device includes a horizontal plate 110 and a second driving component 111. The guiding device includes a round rod 112 and a T-shaped sliding sleeve 113. The aforementioned solution solves the problem that in existing front-end frame connecting beam punching dies, small waste chips easily fly everywhere during punching, causing injury to workers around the die and hindering safe processing. It is understood that the aforementioned solution can prevent small waste chips from flying everywhere during punching, improving processing safety.

[0022] In this embodiment, a guide limiting mechanism 102 is symmetrically arranged on the base 101. The guide limiting mechanism 102 consists of a transverse base and multiple rotating rollers. The transverse base is fixed by positioning pins and bolts. The two ends of the multiple rotating rollers are installed by bearings and are arranged in a row to abut against the two ends of the workpiece.

[0023] The protective cover 103 consists of a connecting part 1031 and a protective part 1032. The connecting part 1031 is detachably connected to the base 101 via a connector 114. The mounting plate 104 is integrally mounted on the base 101. The first driving member 105 is mounted on the bottom of the mounting plate 104, and its output end is detachably connected to the punching cutter 106. The fixed blade holder 107 is mounted on the base 101 and located directly above the punching cutter 106, and is provided with a matching blade groove. The limiting block 108 is mounted on the fixed blade holder 107. The pressure plate 109 is vertically slidably disposed between the guide limiting mechanisms 102. The descending device is disposed on the top of the base 101 and connected to the pressure plate 109. The guide device is disposed on both sides of the pressure plate 109, and four sets are provided. The connecting part 1031 on the protective cover 103 is a rectangular block with holes, integrally formed with the protective part 1032. The connecting part 114 uses a T-shaped screw and nut for installing the protective cover 103. The first driving part 105 is a hydraulic cylinder, which is set at the bottom of the mounting plate 104. Its output end is connected to the mounting disc by a countersunk bolt. The disc is fixed to the punching tool 106 by bolts. The fixed tool holder 107 is used to cooperate with the punching tool 106 to realize the punching of the workpiece, and is provided with a matching tool groove for punching cooperation. The fixed tool holder 107 can also be integrally formed with the base 101 to improve strength. The limiting block 108 is fixed by a positioning pin and bolts and is used to set the end allowance when punching the workpiece.

[0024] Secondly, the limiting block 108 is composed of a fixing part 1081 and a limiting part 1082 forming an L-shaped structure, and the limiting block 108 of different lengths can be replaced for limiting purposes. By replacing the limiting block 108 of different sizes, specifically the limiting block 108 of different lengths of fixing part 1081, it is possible to perform punching processing on workpieces with different allowances using a single mold.

[0025] Then, the horizontal plate 110 is detached from the base 101 and located on top of the base 101; the second drive member 111 is mounted on the horizontal plate 110, and its output end is connected to the pressure plate 109. The horizontal plate 110 is fixed by positioning pins and bolts. The second drive member 111 is a hydraulic cylinder, located on top of the horizontal plate 110, and a disc is mounted on its output end by countersunk bolts. The disc is connected to the pressure plate 109 by bolts, and the pressure plate 109 slides vertically in contact with the rotating roller.

[0026] Finally, the round rod 112 is integrally formed with the pressure plate 109; the T-shaped sliding sleeve 113 is detachably connected to the horizontal plate 110 and slidably connected to the round rod 112. The T-shaped sliding sleeve 113 is fixed by positioning pins and bolts and slidably engages with the round rod 112. When the second driving member 111 moves to drive the pressure plate 109 upward, a feeding chamber is formed between the base 101 and the pressure plate 109, allowing the workpiece to be conveyed.

[0027] When using this invention to avoid the flying of small debris during punching and improve processing safety, the workpiece is first transported by the guide limiting mechanism 102 and limited by the limiting block 108 to ensure that the punching allowance of each workpiece is consistent. Then, the downward device drives the pressure plate 109 to move downward and press and fix the workpiece. Further, the first driving member 105 drives the punching cutter 106 to move upward and, with the cooperation of the fixed cutter holder 107, punches and cuts the end of the workpiece. Then, the debris that flies out during punching is isolated and protected by the protective part 1032 of the protective cover 103 to prevent it from flying away. After being ejected, the waste chips will cause impact to the operator. Finally, the waste chips will fall out through the bottom outlet of the protective cover 103. When the first driving component 105 drives the punching cutter 106 to reset downward, the punching cutter 106 and the upper surface of the mounting plate 104 have a safe distance to avoid the waste chips affecting its reset. The circular guide rods symmetrically arranged on the punching cutter 106 will directly slide and cooperate with the T-shaped linear sliding bearing installed on the mounting plate 104. This can solve the problem that when the existing front frame connecting beam punching die is punched, the small waste chips during punching are easy to fly around and will cause injury to the processing personnel around the die, which is not conducive to safe processing and production.

[0028] Example 2:

[0029] like Figure 4 and Figure 5 As shown, where Figure 4 This is a schematic diagram of the overall structure of the front frame connecting to the crossbeam punching die. Figure 5 yes Figure 4 The enlarged view at point A shows that, based on the first embodiment, this utility model provides a front-end frame connecting beam punching die, which further includes a quick-change mechanism, comprising a rectangular plate 201 and a threaded pin 202.

[0030] The rectangular plate 201 is detachably mounted on the protective cover 103 via the threaded pin 202 and is located on the inclined surface of the protective cover 103. Through holes are provided at the four corners of the rectangular plate 201 to facilitate the installation of the T-shaped threaded pin 202. A rectangular block is provided on the threaded pin 202 for easy rotation, and a through hole is provided on the rectangular block for easy insertion of a force-applying rod for assistance.

[0031] In this embodiment, when the limiting block 108 needs to be replaced later, the four threaded pins 202 can be removed directly, and then the rectangular plate 201 can be removed. Since the rectangular plate 201 is relatively lighter than the protective cover 103, it will be convenient to replace the limiting block 108.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
