Description

A kind of thrust structure being applied to sand core drying production line

Technical field

This utility model is related to casting field and in particular to a kind of thrust structure being applied to sand core drying production line.

Background technology

Core pallet is disposed on the roller-way of sand core drying production line, core pallet mobile transport sand is promoted by roller-way Core, when transporting core to core Hoisting Position, needs to dispose stone tongs in core both sides, core is clamped lifting；And This position, often due to core pallet is mutually adjacent, leads to the spacing between two cores too small, and suspender cannot be introduced into two sand Gap between core, can only be clamped to core in the both sides of roller-way so that operator cannot smoothly complete lifting Work, is needed at least two operator to divide row core to be clamped with production line roller-way both sides simultaneously, or then needs one Name operator beat up and down installations in the both sides of production line, increased human cost and time cost, have impact on and entirely produce The production efficiency of line.

Utility model content

For the problems referred to above, the technical problems to be solved in the utility model is to provide and is applied to sand core drying production line Thrust structure, when core pallet is along roller-way movement to Hoisting Position, coordinates thrust terminator structure to follow-up by limit switch Core pallet carries out thrust, thus ensureing that core two ends are left enough suspenders and entered space.For achieving the above object, this practicality New employing technical scheme is as follows：

A kind of thrust structure being applied to sand core drying production line, including production line roller-way, is placed on production line roller-way Core pallet；It is sequentially provided with limit switch and thrust terminator at the position of lifting core on described production line roller-way；Described only Thruster includes bearing and is arranged at the cylinder in bearing and travel(l)ing rest, and described bearing is by base plate and vertical with base plate both sides The side wall composition connecting, the U-shaped profile of bearing, the cylinder ends of described cylinder are connected with bearing by first rotating shaft, institute State travel(l)ing rest and include two pivoted arms, arbitrarily described pivoted arm is all the L-shaped structure being formed by connecting by forward arm and rear pivoted arm, described Front pivoted arm is adjacent with the junction of rear pivoted arm and the base plate of bearing, and the front pivoted arm described in two passes through the second rotating shaft and holder top Connect, between the rear pivoted arm described in two, be connected with the 3rd rotating shaft, and the end of pivoted arm is connected with and cuts somebody's hair after two；Described gas The piston rod end of cylinder is connected with the 3rd rotating shaft.

Further, described limit switch and thrust terminator are located on the center line of production line roller-way, and described limit switch with only The distance between thruster is more than the length of core pallet.

Further, described core pallet is provided with the recess matching of cutting somebody's hair with described thrust terminator.

The beneficial effects of the utility model are：This utility model construction convenient, the core lifting on production line roller-way Position, setting limit switch and thrust terminator structure, when at previous core pallet movement is to limit switch, thrust terminator cylinder moves Cutting somebody's hair as jack-up stops follow-up core pallet from moving on, and the suspender leaving abundance to the core two ends in previous pallet enters Enter space；After previous core pallet leaves limit switch, thrust terminator cylinder action is packed up and is cut somebody's hair, follow-up core pallet with Can be again introduced into Hoisting Position, repeat a upper process；This utility model structure is simple, repacking facility, can effectively solve Core is difficult to a lifting difficult problem because what spacing closely led to excessively, decreases the burden of operator, saves the operating time, improves life Produce efficiency.

Brief description

Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in further detail, wherein：

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the front view of thrust terminator；

Fig. 3 is the top view of thrust terminator；

Fig. 4 is the right view of thrust terminator.

Specific embodiment

With reference to a kind of thrust structure being applied to sand core drying production line shown in Fig. 1, including production line roller-way 1, dispose Core pallet 2,3 on production line roller-way 1.

Production line roller-way 1 is only to arrange conveying roll, centre no drum structure in both sides；In lifting on production line roller-way 1 It is sequentially provided with limit switch 4 and thrust terminator 6 at the position of core；Described limit switch 4 and thrust terminator 6 are located at production line roller-way 1 Center line on, limit switch 4 is located immediately at below core pallet, and thrust terminator 6 is arranged in the fluting 5 in the middle of production line roller-way 1, The distance between described limit switch 4 and thrust terminator 6, more than the length of core pallet 2,3, prevent thrust terminator 6 from interfering core pallet Normal transport.

With reference to shown in Fig. 2 to Fig. 4, described thrust terminator 6 includes bearing 61 and the cylinder 62 being arranged in bearing 61 and lives Dynamic support 63.

Described bearing 61 is to form, the U-shaped profile of bearing by base plate and with base plate both sides side connected vertically wall.Institute The cylinder ends stating cylinder 62 are connected with bearing 61 by first rotating shaft 64, and described travel(l)ing rest 63 includes two pivoted arms, arbitrarily Described pivoted arm is all the L-shaped structure being formed by connecting by forward arm 63a and rear pivoted arm 63b, described front pivoted arm 63a and rear pivoted arm 63b Junction adjacent with the base plate of bearing 1, pass through the second rotating shaft 65 between the front pivoted arm 63a described in two with bearing 1 top even Connect, between the rear pivoted arm 63b described in two, be connected with the 3rd rotating shaft 67, and the end of pivoted arm 63b is connected with and cuts somebody's hair after two 66；The piston rod 62a end of described cylinder 62 is connected with the 3rd rotating shaft 67.

Described core pallet 3 is provided with 66 recesses 7 matching of cutting somebody's hair with described thrust terminator 6.

Utility model works process is as follows：Preceding core pallet 2 moves to spacing opening after entering lifting core position Close above in the of 4, limit switch controls source of the gas to make cylinder 62 action, and the piston rod 62a of cylinder 62 stretches out promotion travel(l)ing rest 63 and makes Travel(l)ing rest 63 is lifted up so that cutting somebody's hair 66 interceptions on the path of follow-up core pallet 3, recessed on follow-up core pallet 3 Mouthfuls 7 contact stopping and move on cutting somebody's hair；The both sides that suspender is clamped in the core having been enter into station by staff complete to lift； After the completion of lifting, core pallet 2 moves on and leaves above limit switch 4, and the piston rod 62a of cylinder 62 retracts therewith, activity Frame 63 falls, and cutting somebody's hair 66 is separated with the recess 7 of core pallet 3, and core pallet 3 can enter Hoisting Position, the action before repetition Process.

The above, the only preferable specific embodiment of this utility model, but this utility model protection domain does not limit to In this, any those familiar with the art in the technical scope that this utility model discloses, the change that can readily occur in Change or replace, all should cover within protection domain of the present utility model.Therefore this utility model protection domain is with claim The protection domain of book is defined.
