Description

Technical Field

[0001] The utility model relates to a metal wire blanking device in the processing of a pet cage, in particular to a pneumatic blanking mechanism, and belongs to the technical field of pet cage processing. Background Art

[0002] The processing of pet cages is made by welding together multiple metal wire (iron wire) meshes. Each metal wire mesh is welded together by a rectangular wire frame and a number of horizontal / vertical wires. Therefore, in this step of processing, the wires need to be transported to the welding rack for material arrangement and subsequent welding work.

[0003] The common way to transport wires is to manually place them one by one on the welding machine; this method is cumbersome, time-consuming and labor-intensive, and cannot be operated in batches, which is inefficient. Therefore, in order to improve work efficiency, it is possible to use special equipment to directly complete the batch work (for example, using magnetic suction and presetting the wire arrangement spacing), and complete the adsorption of the wires according to the preset spacing before placing them on the welding rack. Then, the equipment with the adsorbed wires is moved to the position directly above the welding rack through a linear guide rail, and the equipment is demagnetized to allow several wires to align with the corresponding wire grooves of the welding rack for dropping;

[0004] During the blanking process, there may be a time difference in the partial disappearance of the magnetic force after the equipment is demagnetized, resulting in the situation that the iron wire cannot fall from the equipment in time, the blanking speed is slow, and the normal blanking is affected. Utility Model Content

[0005] In view of the difficulty in blanking the above-mentioned metal wire, the purpose of the utility model is to provide a pneumatic blanking mechanism, which adopts a pneumatic method to realize the synchronous blanking of metal wire in batches and improve the efficiency of the blanking process; it does not require manual blanking and has the characteristics of simple structural design and easy operation.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a pneumatic punching mechanism, including: a pressing unit and a punching unit; the pressing unit includes a pressing cylinder, a pressing plate, a buffer mechanism and a connecting beam; the telescopic end of the pressing cylinder is fixedly connected to the connecting beam, the lower part of the connecting beam is connected to the buffer mechanism, and the bottom of the buffer mechanism is installed on the pressing plate; the punching unit is arranged on the pressing plate, and a plurality of pressing grooves are arranged on the lower surface of the pressing plate for pressing materials;

[0007] Furthermore, a permanent magnet or an electromagnet is provided at the bottom of the pressing plate;

[0008] As described above, when the pressing unit needs to press the iron wire, a number of iron wires are laid flat on the plane, and the entire pressing unit is moved downward by the action of the pressing cylinder until the pressing plate is pressed on the iron wires; the iron wires are adsorbed in the corresponding pressing grooves on the lower surface of the pressing plate, and then the pressing cylinder is driven to move upward, thereby completing the material removal;

[0009] Furthermore, the connecting beam is two vertical plates parallel to each other, the pressing cylinder is located in the middle between the two vertical plates, and the telescopic rod of the pressing cylinder is fixedly connected to the two vertical plates;

[0010] Furthermore, the structures of the material pressing unit and the material beating unit respectively arranged below the two ends of the connecting beam are two identical and mutually symmetrical independent structures;

[0011] Furthermore, each of the independent structures comprises, from top to bottom: a buffer mechanism connecting plate, a buffer mechanism, two long pressing plates, a pressing connecting plate, bolts, and a punching unit located above both ends of the two long pressing plates; the punching unit is in two sets, each arranged at both ends of the long pressing plate;

[0012] Furthermore, the buffer mechanism includes four guide pillars, and a buffer spring is arranged at the lower end of each guide pillar near the upper end surface of the pressing plate; the four guide pillars are arranged in a rectangular shape and are fixedly connected to the four corners of the buffer mechanism connecting plate by bolts, and the upper end surface of the buffer mechanism connecting plate is fixedly connected to the lower end surface of the connecting beam end;

[0013] Furthermore, the lower ends of the four guide pillars are two long pressing plates arranged in parallel, and a gap is set between the two pressing plates; the two long pressing plates are parallel to each other and are both arranged vertically with the connecting beam in space, and the two ends of the two long pressing plates are connected together on the upper surface by a pressing connecting plate and fixed by bolts;

[0014] The purpose of setting the guide column on the long pressing plate is to provide a buffer for the pressing unit when pressing the wire, so as to prevent the wire from being bent or flattened by excessive impact force.

[0015] Furthermore, the punching unit is located between two long pressing plates; each set of the punching unit includes: a punching cylinder, a cylinder seat, a punching plate and bolts; the outside of the punching cylinder is fixedly connected to the long pressing plate by bolts through a semi-enclosed cylinder seat; the telescopic end of the punching cylinder is fixedly connected to the upper end of the punching plate and fits into the gap between the two pressing plates; the punching plate at the bottom is driven to move up and down by the reciprocating motion of the telescopic rod of the punching cylinder;

[0016] Furthermore, when the punching cylinder is compressed to the limit state, the lower end surface of the punching plate is lower than the lower end surface of the long pressing plate, so as not to affect the adsorption of the lower end surface of the long pressing plate on the iron wire;

[0017] With the above structure, when it is necessary to punch the iron wire adsorbed on the pressing plate, the punching oil cylinder extends its piston rod, driving the punching plate to move downward until it moves to the position of the lower end surface of the punching plate and protrudes downward from the lower end surface of the pressing plate, so that the iron wire is separated from the lower end surface of the pressing plate and falls into the welding rack, thereby completing the punching process;

[0018] Furthermore, the pressing groove on the lower surface of the pressing plate includes a plurality of pressing grooves parallel to each other in the axial direction, which are used for axial blanking of the welding rack; the axial iron wire falls into the radial bracket of the welding rack, and the radial bracket is provided with an iron wire groove corresponding to the pressing groove on the lower surface of the pressing plate; when the iron wire adsorption is completed, the two independent structures that adsorb the iron wire are moved to the upper part of the welding rack through the moving parts, and at this time, the iron wire in the pressing groove of the pressing plate is driven into the iron wire groove of the welding rack through the pressing unit, thereby completing the blanking;

[0019] Furthermore, the wire groove of the radial bracket is a structure with a trumpet opening at the top and a vertical groove at the bottom. The design of the groove with a large upper opening structure makes it easier for the wire to fall into the wire groove of the welding rack when it falls.

[0020] Furthermore, a detection device mounting plate is provided on the outer side of the two independent structures of the long pressing plate, and the detection device mounting plate extends the entire length of the long pressing plate, and a plurality of detection devices are arranged and installed on the detection device mounting plate; each detection device is aligned with each iron wire, and is used to detect whether each pressing groove of the pressing plate adsorbs the iron wire, so as to ensure that the amount of iron wire adsorbed is complete.

[0021] In the above structure, when the two independent units that adsorb the iron wire move to the moving part above the welding rack, the sliding rail is adopted. When it moves to the top of the welding rack, it stops, and then the iron wire falls into the iron wire groove of the welding rack through the punching unit.

[0022] The beneficial effects of the pneumatic punching mechanism of the utility model are:

[0023] This mechanism is used for the blanking of the welding rack of the equipment that has completed the material arrangement. It realizes batch and synchronous blanking of metal wires through magnetic attraction and adopts pneumatic method as driving force.
