Description

A kind of air-conditioning heat transfer sheet multi-station progressive die shut-off mechanism

Technical field

The utility model relates to a kind of air-conditioning heat transfer sheet multi-station progressive die shut-off mechanism, belongs to punch press technical field.

Background technology

Heat transfer sheet is a kind of member being widely used on the equipment such as automobile aluminum radiator of water tank, cocurrent flow type condenser, parallel flow evaporators, radiator or surface cooler, air quantity variable air conditioner cabinet, fan coil and heat exchanger, and its Main Function is the effect of playing heat radiation.In heat transfer sheet is produced, due to the shape of heat transfer sheet various (that the shape of heat transfer sheet has is straight, stagger arrangement and corrugated etc.) feature, the accurate cut-out of heat transfer sheet length is an industry difficult problem always.Existing cutting machine remainder erron is large, the rabbet needs that can not meet actual production of poor quality, is now badly in need of the special-purpose cutting machine of a kind of accurate, high-quality, efficient heat transfer sheet and meets need of production.How steadily to advance heat transfer sheet to move, and with the layout of shearing device be realize accurate, high-quality, efficiently cut off the key of fin.

Utility model content

The utility model object is that the more efficient and accurate air-conditioning heat transfer sheet of a kind of severing multi-station progressive die shut-off mechanism is provided in order to overcome the deficiencies in the prior art.

For achieving the above object, the technical solution adopted in the utility model is: a kind of air-conditioning heat transfer sheet multi-station progressive die shut-off mechanism, comprise cope match-plate pattern, lower bolster, and cut off patrix, cut off counterdie and pushing component; Described cut-out patrix is arranged on the top of lower bolster by upper bolster, between this upper bolster and lower bolster, have elastic parts; Described cut-out counterdie is fixed on lower bolster by die shoe, now cuts off patrix directly over cut-out counterdie one side; Described pushing component comprises cylinder, movable block and connecting plate; Described connecting plate is fixed on cope match-plate pattern, and described cylinder block end is fixed on connecting plate, and cylinder piston rod end is connected on movable block; When cope match-plate pattern moves upward, cylinder operation promotes movable block and moves to and cut off directly over patrix, and when cope match-plate pattern moves downward, the downward crush-cutting of the movable block patrix that break, cuts off patrix and cut off counterdie and coordinate realization cut-out.

As the utility model, further improve, described movable block the place ahead is provided with a block; Described block is fixed on connecting plate, is provided with a spring between this block and movable block.

Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:

A kind of air-conditioning heat transfer sheet multi-station progressive die shut-off mechanism of the utility model scheme, by cutting off patrix, cutting off counterdie and pushing component structural design, realizes efficiently and accurately the cutting off of workpiece, simple in structure, the high and dependable performance of automaticity.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:

Accompanying drawing 1 is the original state schematic diagram of shut-off mechanism for a kind of air-conditioning heat transfer sheet multi-station progressive die of the present utility model;

Accompanying drawing 2 is the working state schematic representation of shut-off mechanism for a kind of air-conditioning heat transfer sheet multi-station progressive die of the present utility model;

Wherein: 1, lower bolster; 2, cope match-plate pattern; 61, cut off patrix; 62, cut off counterdie; 63, upper bolster; 64, elastic parts; 65, die shoe; 66, pushing component; 661, cylinder; 662, movable block; 663, connecting plate; 664, block; 665, spring.

The specific embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.

Accompanying drawing 1,2 is that adjustable clearance shut-off mechanism described in the utility model comprises cope match-plate pattern 1, lower bolster 2, cuts off patrix 61, cuts off counterdie 62 and pushing component 66; Described cut-out patrix 61 is arranged on the top of lower bolster 2 by upper bolster 63, between this upper bolster 63 and lower bolster 2, have elastic parts 64; Described cut-out counterdie 62 is fixed on lower bolster 2 by die shoe 65, now cuts off patrix 61 directly over cut-out counterdie 62 1 sides; Described pushing component 66 comprises cylinder 661, movable block 662 and connecting plate 663; Described connecting plate 663 is fixed on cope match-plate pattern 1, and described cylinder 661 cylinder body end are fixed on connecting plate 663, and cylinder piston rod end is connected on movable block 662; When mould rises, when cope match-plate pattern 1 moves upward, cylinder 661 Work Promote movable blocks 662 move to and cut off directly over patrix 61, when mould declines, when cope match-plate pattern 1 moves downward, the downward crush-cutting of movable block 662 patrix 61 that breaks, cuts off patrix 61 and cuts off counterdie 62 and coordinates realization cut-out;

Described movable block 662 the place aheads are provided with a block 664; Described block is fixed on connecting plate, is provided with a spring 665 between this block 664 and movable block 662, thereby guarantees that cylinder promotes the stability of movable block 662 operations.

Accompanying drawing 1 is shut-off mechanism original state schematic diagram, when cope match-plate pattern 1 is during in extreme lower position, movable block 662 with cut off no matter right side of patrix 61, or 1-1.5mm gap is arranged at top, therefore cut off patrix 61 and can not move, workpiece can pass through shut-off mechanism smoothly, and is not cut off.

Accompanying drawing 2 is shut-off mechanism working state schematic representation, when controller sends shutoff signal, cylinder 661 actions, cylinder piston end stretches out and makes movable block move (10mm) left, now when cope match-plate pattern 1 falls, movable block 662 will promote to cut off patrix 61 whereabouts, coordinate and will make cutting workpiece with cut-out counterdie 62.

When cope match-plate pattern 1 goes back up to most significant end, controller sends stop signal, and cylinder 661 returns to home position, when now cope match-plate pattern 1 falls again, will can not produce cut-out situation.

This adjustable clearance shut-off mechanism, simple in structure, automaticity is high, can realize product and fast and accurately cut off, dependable performance.

Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
