Technical field

The present invention relates to auto parts and components manufacture field, specifically a kind of automobile plastic interior trim moulding hole punched device.

Background technique

Automobile interior decoration plastics have an inner casing, ceiling, seat accommodating groove etc., involved functionality, safety and Engineering attribute is very abundant.Automotive trim plastic parts need to punch wherein during assembly, are fastened on plastics Together, convenient for assembly.

Hole punched device is one of common equipment of automobile interior decoration plastic processing, and hole punched device is downward by the formed punch of top It is mobile, it acts on plastic part, and cooperate the recessed stamping out holes of lower section, Chinese patent (notification number: 208960755 U of CN) A kind of disclosed hole punched device, the product to punching is first placed on to the surface of locating piece, and product is connected to expeller In product limiting slot, product is positioned, but for automotive upholstery, its structure is complicated, the position of punching is more, More support location structure is needed to be replaced, very inconvenient using replacing, therefore, it is necessary to carry out to existing punching position It improves, the punching demand of a variety of positions can be adapted to.

Summary of the invention

The purpose of the present invention is to provide a kind of automobile plastic interior trim moulding hole punched devices, to solve above-mentioned background technique The problem of middle proposition.

To achieve the above object, the invention provides the following technical scheme:

A kind of automobile plastic interior trim moulding hole punched device, including pedestal, support post, hydraulic cylinder and crossbeam；The support is vertical Column is fixedly welded on pedestal vertically, and horizontal crossbeam is fixed in the upper end of support post, and crossbeam is located at the surface of pedestal, Vertical hydraulic cylinder is fixedly installed on crossbeam, the output end of hydraulic cylinder is straight down；In the output end upper and lower sides of hydraulic cylinder Formed punch detachably is installed, is moved down by Driven by Hydraulic Cylinder formed punch, the plastic part of lower section is punched out, it can be according to need Different formed punches is selected, the processing of multiple hole is carried out；It is provided with the positioning plate for placing plastic part below formed punch, leads to Positioning plate support is crossed, is fixed with support frame on the downside of positioning plate, support frame lower end is fixed on the base, and positioning plate is made to be fixed on bottom On seat, plastic part is placed on positioning plate, then is punched out downwards by the formed punch of top；It is arranged in the surface of positioning plate There is horizontal pressing plate, compresses the plastic part of lower section；The adjusting top of vertical face upper platen is installed on the positioning plate Tight block, adjusts the material-dropping hole offered on the central axis of withstanding tight block with formed punch cooperation, and formed punch is moved down from hole on plastic part After extend into material-dropping hole, the plastics to fall off are cleared up away from material-dropping hole；Outer spiral shell is provided on the outer wall for adjusting withstanding tight block Line, corresponding adjusting withstanding tight block position opens up mounting hole on positioning plate, is provided with internal screw thread on the inner wall of mounting hole, makes to adjust For withstanding tight block by being threadably mounted on positioning plate, adjusting withstanding tight block by rotation makes its Level Change, is placed on positioning plate Irregular plastic part can be held out against around punching position by the adjusting withstanding tight block risen or fallen, can not when avoiding punching Support and cause the breakage of other positions；Horizontal toothed disc, toothed disc are coaxially fixed in the lower end for adjusting withstanding tight block Center and adjusting be connected to inside withstanding tight block, convenient for blanking, horizontal spacer pin is provided on the side of toothed disc.

Further: spacer pin includes cap body, cylinder and pinboard, and cap body is fixed on one end of cylinder, and pinboard is solid It is scheduled on the other end of cylinder, is arranged with reset spring on cylinder, one end of reset spring is fixed on the support frame, and in addition one End is fixedly connected in cap body, and the pinboard is laminated structure, and thickness is less than the space width of toothed disc, so as to make to insert Pin plate extend into the between cog of toothed disc, limiting gear disk rotation, when needing pinboard to be detached from out of toothed disc, it is only necessary to outward The tooth disengaging of the pinboard and toothed disc that pull spacer pin to make thereon.

Further: cylinder is prism, cylinder and the support frame clearance fit, and realization is slidably connected, and makes spacer pin It can move in the horizontal direction.

Further: cylinder is quadrangular.

Further: the spacer pin is located at the rightmost side to reset spring in its natural state.

Further: the height of pinboard is the 1/4-1/3 of toothed disc height, can also be led to after moving up and down toothed disc It crosses pinboard to be limited, avoids its rotation.

It is further: vertical gas-pressure mandril is fixedly connected on pressing plate.

Further: gas-pressure mandril is symmetrical set at least provided with two, and two gas-pressure mandril connections are same In gas circuit, moved up and down by two gas-pressure mandril synchronous averaging band dynamic pressure plates.

It is further: it is equipped with cleaning set in the outer sheath of the formed punch, cleaning, which is arranged with, cooperates clean-up port with the formed punch, Formed punch can be passed through out of clean-up port, keep the gap of formed punch and clean-up port small, and the material adhered on formed punch is scraped, and cleaning set is logical Multiple fixed support rods are crossed to be connected on crossbeam.

It is further: to be provided with rubber layer on the inner wall of clean-up port, keep it even closer with punch. contact, by material thereon Material all scrapes.

Compared with prior art, the beneficial effects of the present invention are: the present invention being capable of height by the adjusting withstanding tight block of setting It adjusts, by its rotation and lifting, holds out against it from below in punching position, adapt to automotive trim plastic parts of different shapes, push up Tight punching position can guarantee the integrality of the punching on plastic part, and stress is avoided to concentrate and damage to it, serviceable vehicle The use of upper difference plastics interior trim moulding, improves use scope；The cleaning set of setting can scrape material remaining on formed punch Under, so that formed punch is not carried material when carrying out punching next time, improves the accuracy of punching.
