Heat exchanger for multi-line cutting machine

Abstract

The invention discloses a heat exchanger for a multi-line cutting machine. The heat exchanger comprises a shell fixed with a base, the shell is provided with a cooling water inlet and a cooling water outlet, the cooling water inlet is connected with a cooling water inlet pipe through one end of a tee joint, the other end of the tee joint is connected with a ball valve, the cooling water outlet is connected with a cooling water outlet pipe; both ends of the shell are respectively welded with a pipe plate, part of the pipe plate extending out of the shell is processed to be a flange; both ends of the shell are further respectively and fixedly connected with a first quicksand bore and a second quicksand bore by a flange, the first quicksand bore is connected with a mortar inlet, and the second quicksand bore is connected with a mortar outlet; and a plurality of pipes are arranged in a cavity of the shell, both ends of the pipe are respectively welded on the pipe plates on two ends of the shell, and arranged according to a concentric circle structure on the pipe plate, a pipe plate hole is processed at the connecting part of the pipe plate and the pipe to communciate the pipe. The heat exchanger provided by the invention can effectively control the temperature of the mortar and meets the production demand and the processing requirement.

Description

technical field [0001] The invention relates to the field of multi-wire cutting machines, in particular to a heat exchanger for multi-wire cutting machines. Background technique [0002] The multi-wire cutting machine will generate a lot of heat in the process of cutting the workpiece, and the mortar is attached to the steel wire to cut the workpiece, so it is necessary to accurately control the temperature of the mortar. An increase in mortar temperature can have adverse effects in several ways: [0003] 1). The viscosity of the mortar will decrease, and the sand-carrying ability of the steel wire will decrease; [0004] 2). The performance of the adhesive that will affect the bonding work; [0005] 3). It will cause thermal expansion of the wire rod and affect the machining accuracy; [0006] 4). Affect the ambient temperature, etc. SUMMARY OF THE INVENTION [0007] In order to overcome the deficiencies in the prior art, the present invention aims to provide a heat e...
