Abstract

A demoulding buffer device comprises an air cylinder, a connecting rod and two or more support arms, wherein the tops of the support arms are respectively provided with a rubber block, the air cylinder, the connecting rod and one of the support arm are hinged together, other support arms are hinged with the connecting rod, space between each two adjacent support arms is 1 meter, and the air cylinder forwards or backs to control ascent and descent of the support arms. During usage of the demoulding buffer device, a sleeper falling on the support arms of the buffer device can be buffered well, momentum of the falling sleeper is reduced effectively, cracking of the bottom of the sleeper is overcome effectively, accordingly damage to the sleeper in demoulding is controlled effectively, rejection rate is reduced, and qualification rate of finished products is increased. The demoulding buffer device is simple in structure, and is simple in maintenance and low in maintenance amount as design strengths of all parts of the buffer device are enhanced.

Description

A kind of demoulding buffer

Technical field

The utility model belongs to the railroad sleeper production field, is specifically related to a kind of demoulding buffer that uses in the railroad sleeper manufacturing process.

Technical background

At present, sleeper releasing process: after the hook punching block of die turning-over device rotated 120 °, when punching block decline distance had certain altitude with the finished product roller-way, sleeper fell on the finished product roller-way because of deadweight and model disengaging.But stick together because of a variety of causes causes sleeper and punching block inner bag to be stained with sometimes, sleeper can not separate with the punching block inner bag by deadweight is disposable, and die turning-over device catches punching block and roller-way to collide with repeatedly, just makes sleeper break away from punching block.Because the finished product roller-way is rigidity, as the steel roller, when sleeper falls, certain altitude is arranged, so sleeper forms momentum when dropping to the cylinder of finished product roller-way, cause sleeper to make the bottom surface corner angle collapse piece and fall to take on because of the power of having certain impact.More very be, can not rely on deadweight during the disposable demoulding as sleeper, sleeper is because of being subjected to more external force, even more serious collapse piece and falls mass defect such as shoulder and cause.

The utility model content

The purpose of this utility model be to provide a kind of in the sleeper manufacturing process demoulding damage less, avoid the sleeper bottom to collapse the demoulding buffer of piece.

For realizing this purpose, the utility model has adopted following technical scheme:

A kind of demoulding buffer comprises cylinder, connecting rod and trailing arm.

Described trailing arm is provided with two or more, and the top of described trailing arm is provided with block rubber.

Described cylinder, described connecting rod and a described trailing arm three are hinged, remaining trailing arm and described rod hinge connection, and wherein, two adjacent trailing arm spacings are 1 meter.

Wherein, described cylinder is the helical-lobe compressor cylinder, and pressure is greater than 7Mpa, and moving forward and backward of described cylinder controlled the rising and the decline of trailing arm.The described connecting rod of described air cylinder driven moves backward, and described connecting rod drives trailing arm and rises to the extreme higher position, and demoulding sleeper falls on the trailing arm; When the described connecting rod of described air cylinder driven travels forward, described connecting rod drives trailing arm and reduces to lowest order, and demoulding sleeper falls on the roller on the finished product roller-way, in this motion process, described link motion stroke 450mm, between the extreme higher position of described trailing arm and the extreme lower position drop be 70mm.

In using process of the present utility model, sleeper falls and played good cushioning effect on the trailing arm of buffer, momentum when the minimizing sleeper comes off, realize sleeper " soft landing ", efficiently solve the sleeper bottom and collapse the piece phenomenon, be damaged when the demoulding thereby effectively controlled sleeper, reduce percent defective, improved product qualified rate.This apparatus structure is simple, because each position design strength of buffer is strengthened, it is simple to make device safeguard, maintenance load is little.

Figure of description

Accompanying drawing 1 is a structure chart of the present utility model;

Accompanying drawing 2 is user mode figure of the present utility model;

Accompanying drawing 3 is another user mode figure of the present utility model.

The specific embodiment

Now, further specify the utility model in conjunction with Figure of description.

Referring to accompanying drawing 1, a kind of demoulding buffer comprises cylinder 1, connecting rod 2 and trailing arm.

Present embodiment is provided with two trailing arms, is respectively the first trailing arm 3-1 and the second trailing arm 3-2, and both level intervals are 1 meter, and are in sustained height.The top of the first trailing arm 3-1 is provided with the first block rubber 4-1, and the top of the second trailing arm 3-2 is provided with the second block rubber 4-2.

One end of cylinder 1 and connecting rod 2 and the first trailing arm 3-1 three are hinged, and the second trailing arm 3-2 and connecting rod 2 are hinged.

Rising and the decline of the control first trailing arm 3-1 and the second trailing arm 3-2 that move forward and backward of cylinder 1, when cylinder 1 drive link 2 move backward, the connecting rod 2 drive first trailing arm 3-1 and the second trailing arm 3-2 rise to the extreme higher position; When cylinder 1 drive link 2 travelled forward, connecting rod 2 drives the first trailing arm 3-1 and the second trailing arm 3-2 reduces to extreme lower position.

When using this buffer; shown in accompanying drawing 2 and accompanying drawing 3; the other end of cylinder 1 is hinged on the demoulding finished product roller-way machine frame main beam 5; the first trailing arm 3-1 and the second trailing arm 3-2 are fixed on the crossbeam 6 of demoulding finished product roller-way machine frame; crossbeam 5 is provided with a plurality of sleeper finished product tracks 7, is provided with an ingot stripper 8 simultaneously above the first trailing arm 3-1 and the second trailing arm 3-2.

Before turning over mould, the position of the position of cylinder 1 and connecting rod 2 is on same horizontal linear, and trailing arm rises to the extreme higher position, and the trailing arm top exceeds sleeper finished product track 640mm.At this moment, begin to turn over mould, after sleeper separated from ingot stripper 8, sleeper dropped on trailing arm.

After sleeper fell on the trailing arm, ingot stripper 8 left finished product roller-way 7 tops, and cylinder 1 travels forward; move top along girder 4, and at this moment, trailing arm drops to extreme lower position; sleeper is along with the decline of trailing arm is fallen on the finished product roller-way 7 from the block rubber of trailing arm, and the trailing arm top is than finished product roller-way 7 low 30mm.

By finished product roller-way 7 sleeper is transported at last, entered next operation.

The cylinder source of the gas is that the helical-lobe compressor by the HD-50 type provides, and pressure is greater than 7Mpa.Connecting rod 2 movement travel 450mm, between the extreme higher position of trailing arm and the extreme lower position drop be 70mm.

Above-described the utility model embodiment does not constitute the qualification to the utility model protection domain.Any modification of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
