Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical devices, in particular to a mechanical device with a hand-pinching prevention function. Background Art

[0002] Mechanical parts are an important component of mechanical equipment. Mechanical parts are often extruded during the production and processing. The existing mechanical processing extrusion device with anti-pinch function can protect and avoid pinching during use, but when taking out the product, although it can be pulled and moved, the pulling structure is subjected to the punching force during stamping and may be deformed, which will affect the pulling and pulling process.

[0003] After searching, the Chinese patent document (authorization announcement number CN213856543U) discloses a mechanical processing extrusion device with an anti-pinch function, including a mounting plate and a base, and the four corners of the bottom end of the base are fixedly connected with feet. After the extrusion processing of the mechanical workpiece is completed, the guard plate is opened and the workbench is pulled out of the extrusion working area of ​​the cylinder from the slide grooves inside the top two sides of the mounting plate using the sliders fixed on both sides of the bottom. The limit block fixed on one end of the slider slides in the slide groove to limit and fix the pull-out position of the workbench. After the workbench is pulled out, the mechanical workpiece can be taken out through the ejection mechanism. After the workpiece is taken out, the workpiece to be extruded is placed in the reserved groove and the workbench is pushed back into the mounting frame, thereby achieving the purpose of preventing the user from pinching during the use of the device. Although it can be pulled out and moved, the pull-out structure is subjected to the punching force during punching, and may be deformed, which will affect the pulling process. Utility Model Content

[0004] The utility model aims to provide a mechanical device with a finger-pinch prevention function to solve the problems raised in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a mechanical device with an anti-pinch function, comprising:

[0006] A workbench, on which raw materials for mechanical stamping are arranged;

[0007] A counterweight seat is arranged below the counterweight seat, and a stamping assembly for stamping is connected to the top of the counterweight seat;

[0008] The bottom end of the workbench is connected with a plurality of limit rods, and the top end of the counterweight seat is provided with limit holes for the limit rods to be inserted;

[0009] Two mounting plates are respectively fixed and welded on both sides of the workbench. Multiple electric push rods are embedded in the two mounting plates. The moving parts of the electric push rods are fixedly connected with pulleys for movement. The top of the counterweight seat is provided with two rows of limit grooves adapted to the pulleys.

[0010] Two winches are installed on the top of the counterweight seat. The steel wire ropes of the two winches are connected and fixed to the two sides of the workbench, and are used to pull the workbench to one side to prevent fingers from being pinched when taking materials.

[0011] As a preferred embodiment, the stamping assembly includes:

[0012] Two hydraulic rods, both fixedly connected to the top of the counterweight seat, provide power for the mechanical punching;

[0013] An assembly plate connected to the top ends of the moving parts of the two hydraulic rods;

[0014] The punching block is detachably connected to the bottom end of the assembly plate.

[0015] As a preferred embodiment, a limit block adapted to the punching block is arranged above the workbench, and cameras for recording are installed on the bottom and sides of the assembly plate.

[0016] As a preferred embodiment, the limiting block is provided with a punching channel, and the top of the workbench is provided with a limiting channel for the limiting block to pass through.

[0017] As a preferred embodiment, a taking plate for facilitating taking the limiting block is fixedly connected to the outer periphery of the limiting block, and the workbench is fixedly connected to the taking plate by a locking buckle.

[0018] As a preferred embodiment, the bottom end of the limiting rod is configured as a hemispherical surface for easy insertion into the limiting groove.

[0019] As a preferred embodiment, a plurality of circular channels for the bolts to pass through are provided at the top of the counterweight seat.

[0020] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0021] The mechanical device with the function of preventing fingers from being pinched directly contacts the counterweight seat during stamping, which can increase the contact area compared with the design of the pull-out structure, and does not need to be pulled out, so deformation will not occur. The limit rod prevents the deformation of the workbench during stamping. When it is necessary to move, the electric push rod is controlled to extend, so that the pulley is against the inner wall of the limit groove, the limit rod is separated from the limit hole, the winch on one side is controlled to release the line, and then the winch on the other side is controlled to reel in the line, so as to pull the workbench to move.

[0022] The mechanical device with the function of preventing fingers from being pinched can cooperate with the punching block for punching. When it is necessary to take out the material, the fixing of the lock is released, the limit block is taken out, and the product can be taken away. Different punching needs can be met by replacing different limit blocks and punching blocks.

[0023] The mechanical device with the finger-pinch prevention function is not only more convenient to move, but also convenient to take away the product. BRIEF DESCRIPTION OF THE DRAWINGS
