Abstract

The invention provides a method for manufacturing a mortar pump. The method comprises the steps of conventionally manufacturing a component motor, an upper pump shell, a pump shaft and a feeding pipe, and then combining all the components and connecting all the components by using bolts, thereby forming the mortar pump. The method is characterized in that a lower pump shell and an impeller are respectively manufactured by welding or bonding more than two sub-components which are machined by using section bars. The method has the beneficial effects: 1) the qualified rate and precision of parts are high; 2) the production cost is greatly lowered; and 3) the waste caused by material utilization during the manufacturing process is avoided.

Description

Make the method for mortar pump

Technical field: the present invention relates to the making method of mortar pump in a kind of improved solar silicon wafers multi-line cutting machine, particularly a kind of method of making mortar pump.

Background technique: the making of mortar pump in the existing solar silicon wafers multi-line cutting machine, see accompanying drawing 1, mainly connected and composed after combination and by bolt by shell 2, pump shaft 3, impeller 4, pump lower casing 5, supply pipe 6 these parts on the motor 1 of making according to a conventional method, the pump; Wherein parts pump lower casing 5 and impeller 4 conventional making methods are to form through casting by die sinking.By die sinking through lower pump casing 5 that casting forms and impeller 4 parts and then and other parts after combination and the deficiency that is in use existed by the mortar pump that bolt connects and composes be: 1, the defect rate of lower pump casing 5 and impeller 4 parts is higher, validity is not high, this is because these parts are formed by casting, produce easily the flaws such as trachoma in the parts, burr appears in surface easily; 2, cost of production is high, because mortar pump is the production of corresponding solar silicon wafers multi-line cutting machine, and the yielding capacity of solar silicon wafers multi-line cutting machine is very little, so the yielding capacity of mortar pump is also very little, and pump casing 5 and impeller 4 parts are produced by the die sinking casting up and down, it then is a very high number that its die sinking expense is spread out on each mortar pump, and this is so that each mortar pump cost is very high; 3, cause easily waste in the utilization of material, because its material of parts that forms through casting is single, the requirement to material is different and same parts are at different positions, following pump casing 5, it only will have very high wear resistance to its face that contacts with mortar, and other position does not then require; If with the very high material of the wear resistance whole parts of casting, then cause the waste on the material use, increase cost of production.

Summary of the invention: the object of the invention is to, the deficiency that on the make exists for existing mortar pump, and a kind of parts percentage of A-class goods is proposed, validity is high, cost of production is low, the method for the making mortar pump that material use is good.

Can realize the object of the invention by following technical proposals, a kind of method of making mortar pump, comprise the routine making of shell, pump shaft, supply pipe on component motor, the pump and will connect and compose mortar pump behind whole component combinations and by bolt, it is characterized in that, lower pump casing, impeller are respectively by making through welding or bonding mode through the branch that machinery (cut, grind, dig, cut etc., as follows) processes with section bar more than two.

Described lower pump casing refers to the machined good branch of section bar: three branches, these three branches are three branches in upper, middle and lower that lower pump casing are split to form with vertical mortar pump axis horizontal.

The thickness of middle branch is the width of eccentric groove in the lower pump casing.

Described impeller refers to the machined good branch of section bar: impeller matrix and single impeller blade.

For improving the shock proof function of impeller blade, the impeller matrix is provided with the groove of machined inserted impeller blade part pedestal.

Effect of the present invention is: 1, the percentage of A-class goods of parts, validity height, this is because change has occured in the production method of these parts, having been made into by the production method of casting is the parts branch of cutting apart with the good people of section bar machining first, and then branch is combined into component end item by welding or the mode such as bonding, because component end item is to finish by machining fully, they have not had casting making parts content easily to produce the flaws such as trachoma, and the problem of burr appears in surface easily, and validity is high; 2, cost of production greatly reduces, and this is mainly reflected in this making method and need not die sinking, has saved high die sinking expense; In addition, its percentage of A-class goods is high, and defect rate is low, has saved in the prior art because of the high loss that causes of defect rate; 3, can not cause waste on the material use in making, because described parts are that the branch of cutting apart forms by the people, thereby can be to selecting different materials to make because of different parts to the difference of material requirements in the parts, wear and tear easily such as the blade in the impeller, then can will select high-abrasive material to make as the blade of branch; Eccentric groove place in the pump casing needs very high wear resistance as follows, then can be with the part at the corresponding eccentric groove of upper pump casing place as a branch, select the material making of high wear resistance or heat treatment is done on the surface at eccentric groove place, so can not cause the waste on the material use.

Below in conjunction with drawings and Examples the present invention is further set forth:

Description of drawings:

Accompanying drawing 1 is the structural representation of prior art mortar pump.

Accompanying drawing 2 is the separation structure schematic representation of three branches cutting apart by the people for lower pump casing among the present invention;

Accompanying drawing 3 is the separation structure schematic representation that is divided into branch by the people for impeller among the present invention.

Embodiment:

Referring to accompanying drawing 1,2,3, a kind of method of making mortar pump, the characteristics of the method are parts different in the mortar pump to be made by different production methods, and then parts are connected into the mortar pump finished product in the usual way.The parts of this mortar pump are identical with existing mortar pump, comprise shell 2 on motor 1, the pump, pump shaft 3, impeller 4, pump lower casing 5, supply pipe 6.Shell 2, pump shaft 3, supply pipe 6 these parts are made in the usual way on motor 1, the pump; 5 of impeller 4 and pump lower casings are respectively by being making through welding or bonding mode with the machined good branch of section bar of cutting apart through the people more than two.Impeller 4 or pump lower casing 5 people can determine according to making needs for being divided into several branches.For being divided into three branches in the present embodiment with pump lower casing 5 people, referring to accompanying drawing 2, lower pump casing 5 people are three branches cutting apart: upper branch 51, middle branch 52, lower branch 53, these three branches are split to form lower pump casing 5 with vertical mortar pump axis horizontal.These three branches are machined good with section bar.Three branches can select different materials as required with material.The thickness of middle branch 52 is the width of eccentric groove in the lower pump casing 5.Be that the branch of cutting apart is with impeller 4 people in the present embodiment, referring to accompanying drawing 3, the impeller blade 42 of impeller matrix 41 and several monomers.For improving impeller blade 42 shock proof functions, impeller matrix 41 is provided with the groove 43 of machined inserted impeller blade 42 part pedestals.The impeller blade 42 usefulness section bars of impeller matrix 41 and several monomers are machined good.Impeller matrix 41 and impeller blade 42 can be selected different materials as required.
