Description

Technical Field

[0001] This utility model relates to the technical field of stamping equipment for irregular metal sheet processing, and in particular to a stamping equipment for irregular metal sheet processing. Background Technology

[0002] Currently, drilling of boards often requires interval array drilling, and the holes include both round and irregularly shaped holes. Using traditional equipment can easily lead to board warping, and the drilling efficiency is also low. This solution is proposed to improve and optimize upon these problems and shortcomings. Utility Model Content

[0003] A stamping device for irregularly shaped metal sheet processing includes a stamping machine body. A hydraulic stamping cylinder is fixedly mounted on the bent arm portion of the stamping machine body. A stamping head is disposed at the lower end of the hydraulic stamping cylinder. The stamping machine body also has a slotting fixture and a clamping plate detachably and fixedly connected to the slotting fixture. A metal sheet is inserted into the clamping plate and a pressure plate is mounted on the clamping plate. Bolts for fastening the pressure plate are threaded to the side of the clamping plate. The pressure plate and the clamping plate have holes of a predetermined shape for the stamping head to pass through during stamping.

[0004] Preferably, the slotted clamp is provided with through slots at intervals, and the lower end of the clamping plate is provided with an inverted T-shaped pin that is slidably disposed in the slot. Under the action of the T-shaped pin, the clamping plate cannot move back and forth relative to the slotted clamp, but can move left and right.

[0005] Preferably, electromagnets are embedded at intervals on the slotted clamp. When the electromagnets are energized, they magnetically attract the clamping plate to completely fix the clamping plate.

[0006] Preferably, the main body of the stamping machine is provided with two slide rails, and the left and right sides of the slot clamp are provided with slide grooves that slide with the slide rails, so that the metal sheet can move back and forth while being clamped by the clamping plate and the pressure plate to achieve back and forth interval punching.

[0007] Preferably, an electric push rod is fixedly installed inside the main body of the stamping machine, and the movable end of the electric push rod is fixed to the bottom of the slot fixture by bolts. The electric push rod extends and retracts to drive the slot fixture to move back and forth. An electric push rod is also fixedly installed on the main body of the stamping machine, and a laser calibration plate is arranged at the bottom of the slot fixture. The electric push rod shoots a laser at the laser calibration plate to detect the spacing. When it is necessary to move a specified distance to perform interval drilling, the laser calibration plate moves under the action of the electric push rod, and the laser rangefinder calibrates the amount of movement.

[0008] Preferably, a waste collection frame is provided at the bottom of the slot clamp by means of bolts or magnetic attraction to collect punching waste.

[0009] The advantages and positive effects of this utility model are:

[0010] 1. Pre-fixing by using a clamping plate and a pressure plate can maintain the flatness of the plate during drilling, making it easier to drill more regular and aesthetically pleasing holes.

[0011] 2. The grooved fixture, as a movable fixture carrier, can move back and forth at intervals, facilitating equidistant or non-equidistant drilling and improving efficiency. Attached Figure Description
