DETAILED DESCRIPTION

[0019] The first embodiment of the present application is:

[0020] See also Figure 1-Figure 2 , Figure 1 It is a structural diagram of a mechanical parts stamping machine. Figure 2 It is a cross-sectional view of a punching machine for mechanical parts.

[0021] The utility model provides a mechanical parts stamping machine, including a base 101, a stamping machine body 102, a protective plate 103 and a limiting mechanism 104, wherein the limiting mechanism 104 includes a driving assembly 105, two push plates 106, two rollers 107, two slide bars 108, two fixed plates 109, a guide rail 110, a guide block 111, two baffles 112, two reset springs 113, two guide rods 114 and two limit blocks 115, and the driving assembly 105 includes a cylinder 116, a piston rod 117 and a cross plate 118. The above-mentioned scheme solves the problem that when stamping parts, the parts may be displaced by external forces, resulting in a decrease in the stamping yield of the parts. It can be understood that the above-mentioned scheme can be used in the scene of fixing the parts to be processed, and can also be used to solve the problem that the slide bar 108 cannot be reset.

[0022] According to this specific embodiment, the punch body 102 is arranged on one side of the base 101, the protective plate 103 is arranged on the side of the base 101 close to the punch body 102, the driving assembly 105 is arranged in the base 101, the two push plates 106 are arranged on one side of the driving assembly 105, the two rollers 107 are respectively abutted against the two push plates 106, the two sliding rods 108 are respectively rotatably connected to the rollers 107, and are respectively slidably connected to the base 101, and the two fixed plates 109 are respectively fixedly connected to the two sliding rods 108, and are both located on the side of the sliding rod 108 away from the rollers 107. The punching machine body 102 is a punching machine and an electric control box as described in the prior art. The electric control box is fixedly installed on the right side of the punching machine. A protective mechanism is arranged on the front side of the punching machine. A positioning mechanism is arranged inside the protective mechanism. By setting up the cooperation of the punching machine, the electric control box, the protective mechanism and the positioning mechanism, the user pushes the transmission block toward the side close to the shell, and the transmission block cooperates with the positioning assembly to make the positioning rod leave the inside of the positioning hole. At this time, the shell and the protective plate are rotated around the rotating rod so that the protective plate is located in front of the position where the punching machine punches the mechanical parts. After that, the protective plate is positioned by the positioning mechanism, which solves the problem that the existing punching machine does not have a protective function. When processing some special parts, the waste on the parts may fly out due to the pressure of the punching machine during the punching, causing accidental injury to the user. The base 101 provides installation conditions for the punching machine body 102, the protective plate 103 and the limiting mechanism 104. The punching machine body 102 can be used to process parts. The protective plate 103 can prevent debris from splashing during the processing of parts. The driving component 105 can drive the two push plates 106 to move. The movement of the two push plates 106 can drive the two rollers 107 to move. The movement of the two rollers 107 can drive the two slide bars 108 to slide in the base 101. The sliding of the two slide bars 108 can drive the two fixed plates 109 to move closer to or away from each other. The parts to be processed on the base 101 can be limited and fixed by the two fixed plates 109.

[0023] The cylinder 116 is fixedly connected to the base 101 and is located inside the base 101. The piston rod 117 is fixedly connected to the output end of the cylinder 116. The cross plate 118 is fixedly connected to the piston rod 117 and is fixedly connected to the two push plates 106. The cylinder 116 can drive the piston rod 117 to extend and retract, and the piston rod 117 can drive the cross plate 118 to move toward or away from the cylinder 116. The movement of the cross plate 118 can drive the two push plates 106 to move.

[0024] Secondly, the guide rail 110 is fixedly connected to the base 101 and is located inside the base 101, and the guide block 111 is fixedly connected to the cross plate 118 and is slidably connected to the guide rail 110. The guide rail 110 provides installation conditions for the guide block 111, and when the cross plate 118 moves, the guide block 111 is driven to slide on the guide rail 110, and the cross plate 118 can be guided and limited by the guide block 111.

[0025] At the same time, the two baffles 112 are respectively fixedly connected to the two slide bars 108, and are both located on the side of the slide bar 108 close to the roller 107. The two return springs 113 are respectively fixedly connected to the two baffles 112, and are respectively fixedly connected to the base 101, and are both located between the baffles 112 and the base 101. The two baffles 112 provide installation conditions for the two return springs 113. When the two slide bars 108 approach each other, the two return springs 113 are contracted, and the two slide bars 108 can be pushed to reset by the resilience of the two return springs 113, so that the roller 107 on the slide bar 108 abuts against the push plate 106.

[0026] In addition, the two guide rods 114 are respectively fixedly connected to the two fixing plates 109, and are respectively slidably connected to the base 101, and both penetrate the base 101. The two limit blocks 115 are respectively fixedly connected to the two guide rods 114, and are both located on the side of the guide rods 114 away from the fixing plates 109. When the two fixing plates 109 move, the two guide rods 114 are driven to slide on the base 101. The two guide rods 114 can guide the two fixing plates 109 to improve the stability of the two fixing plates 109 when they move. At the same time, the two limit blocks 115 can limit the two guide rods 114 to prevent the two guide rods 114 from moving out of the preset range.

[0027] When it is necessary to fix the parts, the parts are placed on the stamping machine body 102, and the cylinder 116 is started. The cylinder 116 drives the piston rod 117 to extend, and the piston rod 117 drives the cross plate 118 to move to the side away from the cylinder 116. The cross plate 118 drives the two push plates 106 to move, and the two push plates 106 drive the two rollers 107 to move on the push plates 106. The two rollers 107 drive the two slide bars 108 to approach each other, and then drive the two fixed plates 109 on the two slide bars 108 to approach each other until the two fixed plates 109 contact the parts and clamp the parts. In this way, the parts can be fixed to prevent the parts from being displaced during the stamping process, thereby solving the problem that when the parts are stamped, the parts may be displaced by external forces, resulting in a decrease in the stamping yield of the parts.

[0028] The second embodiment of the present application is:

[0029] See also Figure 3 , Figure 3 It is a structural diagram of a punching machine for mechanical parts.

[0030] On the basis of the first embodiment, in a mechanical parts stamping machine of the utility model, the limiting mechanism 104 further includes a plurality of electric push rods 201 and a plurality of support plates 202 .

The operation of the plurality of electric push rods 201 can drive the plurality of support plates 202 to move toward the side close to the ground or away from the ground, and the plurality of support plates 202 can support the base 101, thereby improving the stability of the base 101, and further improving the stability of the punching machine body 102 when working.

[0032] The operation of the multiple electric push rods 201 can drive the multiple support plates 202 to move toward the side close to the ground or away from the ground. The multiple support plates 202 can support the base 101, improve the stability of the base 101, and further improve the stability of the punch body 102 during operation.
