Description

Rim punching machine

Technical field

The present invention relates to a kind of equipment with impact style punching on wheel rim.

Background technology

The rim punching machine of the wheelchair of prior art, wheel rim are to fix by the anchor clamps that are fixed on the pedestal.Drift is arranged on the wheel rim periphery, and die is arranged within the wheel rim circumference, and the Driven by Hydraulic Cylinder drift carries out punching to wheel rim, and during punching, die will coincide well with wheel rim, otherwise impression can appear in the wheel rim surface.In addition, drift and die poor fit or have to a certain degree after the wearing and tearing, burr can appear in the wheel rim inner surface, and the wheel rim by this operation is produced generally will increase polishing process after the punching, bothers very much and increases cost.When diverse location punching that need be at wheel rim, need to rotate wheel rim, finish punching everywhere successively, so just make a wheel rim often will expend a large amount of circulating times, be unfavorable for reducing production costs and enhancing productivity.

Summary of the invention

Technical problem to be solved by this invention provides a kind of high efficiency and cuts wheel rim is not had the carrot-free substantially rim punching machine of the punching that weighs wounded and process.

For solving above technical problem, the present invention takes following technical scheme:

A kind of rim punching machine, the a plurality of hole punched devices that comprise pedestal, are arranged on the pedestal and distribute along the circumferencial direction of wheel rim, hole punched device comprise punching with drift, be used to drive described drift and finish the driving mechanism of punching press action, be resisted against the die on the inner circumferential surface of wheel rim, described hole punched device also comprises the hold mode on the side surface that is supported on wheel rim, and rim punching machine also comprises and is used to make die to push against strainer at the inside circumference face of wheel rim.

Offer a plurality of slide rails that radially extend on the described pedestal along wheel rim, rim punching machine also comprises the slide that is slidingly arranged on the slide rail, a plurality of hole punched devices are fixedly installed on respectively on a plurality of slides, described strainer comprises the lifting round platform of the center that is positioned at wheel rim, is arranged on regulating wheel on the die rotationally, and the part surface of regulating wheel is adjacent to mutually with the outer surface of lifting round platform.

Rim punching machine also comprises and is used to drive the driving cylinder that the lifting round platform moves up and down, and the lifting round platform is fixedly connected on the free end of piston rod of described driving cylinder.

Described hole punched device has four, and the direction of motion of adjacent hole punched device is perpendicular.

The cross section of described drift is square.

Described driving mechanism is an oil cylinder, and drift is fixedly mounted on the free end of beam hanger of oil cylinder.

Thereby described hole punched device also comprises be used for compressing the hold-down mechanism that wheel rim prevents that it from popping up when punching.

Described hold-down mechanism comprises hold-down cylinder and is plugged in the interior depression bar of described hold-down cylinder slidably that during punching, described compressor arm is against on the upper side of described wheel rim.

Offer the hole that can supply drift to pass on the described die.

Because the utilization of technique scheme, the present invention has the following advantages compared to existing technology:

Wheel rim supports by a hold mode, and is tight against side within it by die, and drift is positioned at the circle lateral surface, and this rim punching machine does not have the punching that weighs wounded and process to wheel rim and do not have burr substantially; Owing to have a plurality of hole punched devices, improved the operating efficiency of rim punching machine greatly; In addition, this rim punching machine also has simple advantage is set.

Description of drawings

The present invention will be further described in detail below in conjunction with specific embodiment:

Fig. 1 is a schematic top plan view of the present invention;

Fig. 2 is that master of the present invention looks schematic diagram;

Wherein: 1, pedestal; 2, hole punched device; 20, drift; 21, driving mechanism; 22, prop up hold mode; 23, die; 24, hold-down mechanism; 3, wheel rim; 4, strainer; 40, lifting round platform; 41, regulating wheel; 42, tensioner arm; 5, driving cylinder; 6, slide rail; 7, slide; 8, hole.

The specific embodiment

Rim punching machine according to present embodiment mainly comprises pedestal 1, is arranged on four hole punched devices 2 on the pedestal 1.

Wheel rim 3 is the center positions that are positioned at pedestal 1.Offer four slide rails 6 on the pedestal 1, these four slide rails 6 distribute along the excircle direction of wheel rim 3, and bearing of trend between any two meets at right angles.Being provided with 7, four above-mentioned hole punched devices 2 of slide on each slide rail 6 slidably is fixedly installed on respectively on the slide 7.

Each above-mentioned hole punched device 2 comprises the driving mechanism 21 of punching with

drift

20,20 motions of driving drift, and the cross section of drift 20 is square, is used to form square opening.Hole punched device 2 also comprises the hold mode 22 that is used to support wheel rim 3, be tight against at the die 23 on interior all sides of wheel rim 3 and be fixedly installed in being used on the described slide 7 and apply a downward power to wheel rim 3, prevents the hold-down mechanism 24 that wheel rim 3 can pop up in punching course.Offer the hole of passing for drift 23 8 on the die 23.

Hole punched device 2 also comprises makes recessed film 23 can be tight against the strainer 4 on interior all sides of wheel rim 3.The tensioner arm 42 that described strainer 4 comprises the inboard center that is positioned at wheel rim 3 and the lifting round platform 40 that can move up and down along its direction of axis line, removably connect mutually with above-mentioned slide 7, be arranged on the regulating wheel 41 of described tensioner arm 42 medial ends rotationally, the part surface of regulating wheel 41 is adjacent to mutually with the circumferential lateral surface of lifting round platform 40.When lifting round platform 40 moved upward, slide 7 will outwards move along slide rail 6, drove the inner surface motion of recessed film 23 towards wheel rim 3, thereby was tight against side within it.

This rim punching machine also comprises the driving cylinder 5 that is used to drive 40 oscilaltions of lifting round platform.

Hold-down mechanism 24 comprises hold-down cylinder 240 and is plugged in depression bar 241 in the described hold-down cylinder 240 slidably that during punching, depression bar 241 is against on the upper side of wheel rim 3.

Above-mentioned driving mechanism 21, driving cylinder 5 and hold-down cylinder 241 are oil cylinder.

To sum up, can not cause weighing wounded of wheel rim basically during rim punching machine punching of the present invention, the hole of going out does not have burr substantially yet; And because a plurality of hole punched devices are set, the operation simultaneously of control hole punched device can will be gone out a plurality of holes, production efficiency height simultaneously on the wheel rim.
