Description

Desk type accurate punching machine

Technical field

The present invention relates to a kind of machining equipment, the desk type accurate punching machine that particularly a kind of volume is little, easy to use, safe and punching precision is high.

Background technology

The desk type accurate punching machine of present commercially available use, its brake part, clutch part is split type, and be installed in respectively frame before, on the back-end location, brake part is a brake ribbon, its two ends all are fixed on and form an annular ring on the frame, along with the rotation of bent axle constantly contacts with bent crank portion of shaft, therefore no matter the flywheel of Clutch Control is to drive or the disengaging bent axle, brake ribbon is all in running order always, promptly add according to the wearing and tearing of brake ribbon increase the consumption of energy again, make braking effect imprecise after time is long, therefore also exist hidden danger, simultaneously the undesirable operating cost that improved again of operating efficiency.Adopt the steel structure that closes of sliding friction in addition between its frame and crankshaft component, so the big coefficient of friction increase of contact area, lubricated insufficient, phenomenons such as heating, locking, serious wear easily produced.

In addition because of connecting rod and Slipper, adopted the ball head connecting rod structure to adjust the height of desk type accurate punching machine mould, but ball head connecting rod requirement on machining accuracy height, difficult processing, and the lower dead center instability, therefore there are many drawbacks such as punching precision is low, mold height adjusting inconvenience.

Summary of the invention

Technical problem to be solved by this invention is: a kind of desk type accurate punching machine is provided, can effectively increases work efficiency, and lubricated fully, brake property is good, punching precision is high, the class that can promote punch press reduces production costs, and practical.

The present invention addresses the above problem the technical scheme that is adopted: desk type accurate punching machine, comprise workbench, the motor of belt leather belt wheel, before, bonnet, bent axle all is installed on the abutment body, be connected with flywheel on the bent axle, clutch, brake, the crank throw place of bent axle is connected with the connecting rod slider device, and slide block cooperates with guide rail, described clutch, brake is a clutch brake component, by the brake pressure plate that has brake block, the clutching pressure plate be installed in body, the piston cooperation of band spring is formed in the cylinder, described clutching pressure plate is connected on the flywheel, described brake pressure plate is connected on the abutment body, described body is connected on the bent axle, it is that air inlet P is connected with source of the gas that there is the blind hole that communicates in length and breadth the centre of described crankshaft rear end, has air inlet to communicate with air inlet P on body one side surface; Described connecting rod slider device will be had an oscillating bearing by pin small end with adjust slide block and be connected, the connecting rod lower end that has needle bearing is connected with bent axle, the saw tooth that has nut, a screw mandrel connects into integral body with slide block and adjustment slide block and constitutes.

Compared with prior art, the invention has the advantages that: 1, original two clutch, brakes that disperse to install are merged into clutch brake component and install concentratedly, not only compact conformation, volume are little, also easily installation and maintenance, the effectively quick combination of control punch press and brake fast, brake property is good, not only enhances productivity, and also uses more flexible, safer; 2, bent axle all adopts rolling bearing with abutment body, flywheel, being connected of connecting rod, has both guaranteed the sufficient lubrication of punch press, has improved working environment again and has reduced resistance, has accelerated velocity of rotation and has improved operating efficiency; 3, be with the connecting rod of oscillating bearing and the connecting rod slider device that adjustment slide block, slide block connect and compose, its compact conformation, the shared useful space is little, dwindled the volume of complete machine greatly, and part is easily processed, easily installation, as long as the turn nut just can carry out the adjusting of mold height, punching precision height, simple to operate, easy to use alleviates working strength of workers and increases work efficiency again.
