Description

Cladding drilling equipment

Technical Field

The invention relates to a mechanical device, in particular to a leather drilling device.

Background

Leather or leather is widely used in social life, and the processing of the round hole on the leather is simple but puzzles the industrial process due to the characteristics of soft quality, toughness and thickness of the leather; the mode of adopting a thread-shaped common drill bit to process holes on the multilayer overlapped leather can be wound to destroy a tool; a plurality of leather processing places adopt a punch stamping mode for processing, the processing mode is feasible for single-layer leather, but multilayer overlapped leather is not feasible, and the work efficiency is difficult to improve; the feasible processing mode is to use a circular-tube-shaped thin-wall drill pipe to process a circular hole on a plurality of layers of superposed leather materials by adopting a circular cutting process, but the problem that the cutting excess materials are plugged into the pipe cavity of the drill pipe to cause the heat dissipation difficulty of the drill pipe and the temperature rise of the drill pipe cutting edge (namely, the pipe opening) hardness reduction and the like often occur when the circular hole is continuously processed on the drill pipe with a simple tubular structure is solved, and meanwhile, the hole reserved on a bedplate under the leather materials for protecting the cutting edge of the drill pipe to accommodate the cutting edge end of the drill pipe penetrating through the leather materials also often influences the processing precision of the hole.

Disclosure of Invention

The invention aims to provide a leather drilling device which can solve the problems.

The technical scheme of the invention comprises the following steps: the drill pipe comprises a drilling machine, a drill pipe and a bedplate, wherein a circle of groove is processed on the circumference of the outer wall surface of the middle area of the drill pipe in length, the areas above and below the groove in a drill pipe barrel are embedded with a spiral spring, namely an upper spring, and the outer end of the upper spring extends to the pipe orifice of the drill pipe and is equal to the pipe orifice; the table plate is provided with a circular socket in the area opposite to the pipe orifice of the drill pipe, a cylindrical cushion box is embedded in the socket, and an upper cushion plate, a bearing, a lower cushion plate and a lower spring are respectively arranged in the cushion box from top to bottom; when the drill pipe is driven by the rotation of a drilling machine to downwards process round holes in leather materials stacked on the bedplate, each layer of residual materials cut off in a circle are sequentially filled into a pipe barrel of the drill pipe, an upper spring in the drill pipe is upwards extruded and compressed by the residual materials, when a stack of stacked leather materials are completely drilled through, a pipe orifice at the lower end of the drill pipe can downwards impact and touch the upper baffle plate of the cushion box, a lower spring can play a role in buffering the lower pressure, and meanwhile, the rotating drill pipe can drive the upper cushion plate to rotate in the same speed and direction so as to avoid the lower end cutting edge of the drill pipe from being collided and worn; the drill pipe is drawn out from the hole of the cladding, and the spring in the drill pipe can eject the excess material plugged in the drill pipe barrel out so as to be beneficial to heat dissipation and processing of the next hole.

The invention has the beneficial effects that: the device can avoid the blockage of the residual material to the pipe barrel, and simultaneously, the leather is powerfully supported to punch a high-precision round hole and protect the cutting edge of the drill pipe.

Detailed Description

The design is illustrated below with reference to the accompanying drawings.

As shown in the illustration in fig. 2, when the hole 7 is processed in the stacked cladding 3 cut into a circle in the drill pipe 2, the excess material is inevitably filled in the pipe barrel of the drill pipe, which is not favorable for heat dissipation of the drill pipe and subsequent continuous drilling operation; as shown in fig. 1 and fig. 3, the drilling device of the design comprises a drilling machine 1, a drill pipe 2 and a bedplate 4, wherein a circle of groove 8 is processed on the circumference of the outer wall surface in the middle of the length of the drill pipe 2, a spiral spring, namely an upper spring 6, is embedded in the upper and lower areas of the groove in the drill pipe barrel, the outer end of the upper spring extends to the pipe orifice of the drill pipe 2 and is equal to the pipe orifice, the upper spring is embedded and fixed at the inner end of the upper spring through the diameter of the drill pipe reduced at the groove, the two ends of the drill pipe are subjected to cutting edge processing and the upper spring is arranged, so that the two ends of the drill pipe can continuously work in sequence to improve the working efficiency, the drill pipe is drawn out from the hole of the leather material after drilling, and the spring in the drill pipe, namely the upper spring 6 can pop out the residual material in the drill pipe barrel so as to be beneficial to heat dissipation and; the table plate 4 is provided with a circular socket in the area facing the mouth of the drill pipe, when drilling, the lower end of the drill pipe will extend into the socket of the table plate after drilling down through the cladding to serve as a buffer area for the drill pipe to rotate upwards (so as to avoid the impact of the table plate surface on the drill pipe cutting edge from touching), however, the hole processing of many cladding workpieces requires accurate positioning, the table top facing the drill pipe loses strong support due to the existence of the socket for accommodating the drill pipe, the drilling position often generates slight deviation from the drawing requirement, the quality requirement of the workpiece is greatly reduced due to the drilling precision, in view of this, a cylindrical pad box 5 is embedded in the socket, and as shown in fig. 1, 4 and the enlarged view thereof, the pad box 5 is respectively provided with an upper pad plate 9, a bearing 10, a lower pad plate 11, and a lower pad plate from top to bottom in the box, A lower spring 12; when the drill pipe is driven by the rotation of a drilling machine to downwards process round holes in leather materials stacked on the bedplate, each layer of residual materials cut off in a circle can sequentially enter a pipe barrel of the drill pipe, an upper spring in the drill pipe is upwards extruded and compressed by the residual materials, when a stack of stacked leather materials are completely drilled through, a pipe orifice at the lower end of the drill pipe can downwards impact and touch the upper baffle plate of the cushion box, a lower spring can play a role in buffering the impact of downward force at the time, and meanwhile, the rotating drill pipe can drive the upper cushion plate to rotate at the same speed and in the same direction so as to avoid the lower end cutting edge of the drill pipe from being collided and worn; the powerful supporting requirement of high accuracy perforation to the cladding has been satisfied on the one hand in the setting of pad box, and on the other hand does not influence the drill pipe and is becoming ascending buffering conversion by downwards for awkward cladding operation problem of punching has obtained thorough solution.
