Description

Technical Field

[0001] This utility model relates to the field of chamfering machine technology, and in particular to a quick-change chamfering mold mechanism and a chamfering machine. Background Technology

[0002] After metal parts are formed, a chamfering machine is needed to chamfer them, both to remove burrs generated during machining and to facilitate assembly. Because chamfering machines need to be suitable for chamfering metal parts of different sizes, various chamfering dies of different sizes need to be designed. The appropriate chamfering die size is selected based on the size of the metal part to be chamfered, and then installed on the chamfering base mold. Existing chamfering dies are installed on the chamfering base mold using multiple bolts, making installation and disassembly relatively complex. Therefore, a quick-change chamfering die mechanism and chamfering machine need to be designed to simplify the installation and disassembly of the chamfering die, thus facilitating its removal from the chamfering base mold. Utility Model Content

[0003] To address the problems in the prior art, this application proposes a quick-change chamfering mold mechanism and chamfering machine, which simplifies the installation and disassembly of the chamfering mold, thereby facilitating the removal and installation of the chamfering mold from the chamfering base mold.

[0004] One aspect of this utility model provides a quick-change chamfering mold mechanism, which includes a chamfering bottom mold and a chamfering mold. The chamfering bottom mold includes at least two bottom mold segments, each with a mounting cavity. The bottom mold segments surround each mounting cavity to form a mounting cavity, and the chamfering mold can be positioned within the mounting cavity. The chamfering mold includes at least two mold segments, each mold segment correspondingly installed within each mounting cavity. Each mold segment has a limiting rod with a limiting groove. The bottom mold segment has a limiting hole penetrating the inner wall of the mounting cavity, and the limiting rod can extend into the limiting hole. A limiting mechanism is installed on the bottom mold segment, and the limiting mechanism can be confined within the limiting groove on the limiting rod extending into the limiting hole to fix the mold segment to the bottom mold segment.

[0005] As a further improvement to the above technical solution:

[0006] Furthermore, in the aforementioned quick-change chamfering mold mechanism, the limiting groove is opened along the circumference of the limiting rod.

[0007] The aforementioned quick-change chamfering mold mechanism further includes a limiting mechanism comprising a limiting base, an elastic element, and a limiting pin. The bottom mold piece has a mounting hole, and the limiting base is fixedly installed within the mounting hole. The limiting base also has a sliding hole, and the limiting pin is slidably installed within the sliding hole. A limiting annular groove is formed on the inner sidewall of the sliding hole, and the elastic element is installed within the limiting annular groove. A limiting block is provided on the sidewall of the limiting pin, and the limiting block can extend into the limiting annular groove. Both ends of the elastic element abut against the ends of the limiting block and the limiting annular groove, respectively. The elastic element can drive the limiting pin to extend into the limiting groove on the limiting rod within the limiting hole.

[0008] Furthermore, in the aforementioned quick-change chamfering mold mechanism, a drive handle is installed at the end of the limiting pin away from the limiting hole. The drive handle is used to pull the limiting pin to overcome the action of the elastic element so that the limiting pin exits from the limiting groove on the limiting rod in the limiting hole.

[0009] Furthermore, in the aforementioned quick-change chamfering mold mechanism, the bottom mold piece is provided with bolt holes, through which bolts can pass to install the bottom mold piece onto the frame of the chamfering machine.

[0010] Another aspect of this utility model provides a chamfering machine, which includes the quick-change chamfering mold mechanism as described above.

[0011] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of this utility model can be achieved.

[0012] This utility model provides a quick-change chamfering mold mechanism and chamfering machine, which, compared with the prior art, has at least the following advantages: When the chamfering mold to be replaced needs to be installed on the chamfering bottom mold, firstly, the limiting rods on each mold segment are installed one by one into the limiting holes on each bottom mold segment. Then, the limiting mechanisms on each bottom mold segment are driven to be limited to the limiting grooves on the limiting rods extending into the limiting holes, so as to fix the mold segment on the bottom mold segment. Finally, each bottom mold segment is installed on the frame of the chamfering machine, thereby completing the replacement of the chamfering mold. When the chamfering mold to be disassembled needs to be removed from the chamfering bottom mold, firstly, each bottom mold segment is removed from the frame of the chamfering machine. Then, the limiting mechanisms on each bottom mold segment are driven to retract from the limiting grooves on the limiting rods extending into the limiting holes. Finally, the limiting rods on each mold segment are retracted from the limiting holes on each bottom mold segment. This quick-change chamfering mold mechanism only requires the driving limiting mechanism to extend into or retract into the limiting groove on the limiting rod extending into the limiting hole to realize the installation and removal of the chamfering mold on the chamfering bottom mold. Compared with the existing technical solutions, the technical solution of this application simplifies the installation and removal of the chamfering mold, thereby facilitating the removal and installation of the chamfering mold from the chamfering bottom mold.

The limiting mechanism 140 can be limited within the limiting groove 131 on the limiting rod 130 that extends into the limiting hole 114, so as to fix the mold piece 121 onto the bottom mold piece 111.

[0033] When the chamfering mold 120 to be replaced needs to be installed on the chamfering bottom mold 110, firstly, the limiting rods 130 on each mold segment 121 are installed one by one into the limiting holes 114 on each bottom mold segment 111.

When the chamfering mold 120 to be disassembled needs to be removed from the chamfering bottom mold 110, firstly, each bottom mold piece 111 is removed from the machine frame of the chamfering machine.

Figure 5 The limiting groove 131 is opened along the circumference of the limiting rod 130.

[0036] When the chamfering mold 120 to be replaced needs to be installed on the chamfering bottom mold 110, firstly, the limiting pins 143 on each bottom mold segment 111 are driven to overcome the elastic element 142 so that the limiting pins 143 are withdrawn from the limiting holes 114. Then, the limiting rods 130 on each mold segment 121 are installed one by one into the limiting holes 114 on each bottom mold segment 111. Then, under the action of the elastic element 142, the limiting pins 143 on each bottom mold segment 111 extend into the limiting grooves 131 on the limiting rods 130 in the limiting holes 114 to fix the mold segment 121 to the bottom mold segment 110. 1.

In this embodiment, the drive handle 147 is arranged around the end of the limiting pin 143 away from the limiting hole 114. When driving, a person holds the drive handle 147 to pull the limiting pin 143 to overcome the action of the elastic member 142, so that the limiting pin 143 exits from the limiting groove 131 on the limiting rod 130 in the limiting hole 114. A bolt hole 116 is provided on the bottom mold piece 111, and a bolt can pass through the bolt hole 116 to install the bottom mold piece 111 on the frame of the chamfering machine.
