Description
Technical Field
[0001] The utility model relates to the technical field of plate heat exchanger maintenance, and particularly relates to a plate heat exchanger plate shaping tooling. Background Art
[0002] A plate heat exchanger is an efficient heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. The plate heat exchanger is an ideal device for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small floor area, wide application, long service life, etc.
[0003] In the prior art, micro-leakage may occur during the actual use of the plate heat exchanger.

[0031] The following will describe the embodiments of the present utility model in detail with reference to the drawings.
[0032] As shown Figures 1 to 5 in the figure, the utility model discloses a plate heat exchanger plate shaping tooling, which includes a shaping table 1. The shaping table 1 is rectangular. An edge groove shaping mechanism 3 and a circular groove shaping mechanism 2 are arranged on the shaping table 1. When the plate is placed on the shaping table 1, the edge groove shaping mechanism 3 and the circular groove shaping mechanism 2 quickly shape the sealing grooves of the plate to make it return to normal.
[0033] The edge groove shaping mechanism 3 is arranged at one end of the shaping table 1 and includes a vertically arranged support column 31. A slider 32 is slidably arranged on the side wall of the support column 31, and an edge groove pressing rod 33 is hinged on the slider 32. A chute 37 is vertically opened on the side wall of the support column 31 close to the inner side of the shaping table 1. The slider 32 is slidably connected with the chute 37, and an adjusting component is arranged between the slider 32 and the chute 37. The height of the slider 32 in the chute 37 can be adjusted through the adjusting component. The adjusting component includes an adjusting screw rod 36 rotatably arranged in the chute 37. The adjusting screw rod 36 is vertically arranged and is in threaded cooperation with the slider 32. The bottom end of the adjusting screw rod 36 is rotatably connected with the support column 31 at the bottom of the chute 37. The top end of the adjusting screw rod 36 is rotatably connected with a support plate 38, and the support plate 38 is connected with the inner wall of the chute 37. The top end of the adjusting screw rod 36 above the support plate 38 is coaxially connected with a regular hexagonal prism-shaped head. The head can be rotated by a socket wrench to make the adjusting screw rod 36 rotate, and the threaded cooperation between the adjusting screw rod 36 and the slider 32 realizes the lifting of the slider 32 in the chute 37.
[0034] An edge groove pressing block 34 in contact with the lower part of the edge groove pressing rod 33 is arranged. The edge groove pressing block 34 is strip-shaped, and the shape and size of its bottom are adapted to the edge groove of the plate. A cushion block 35 is arranged on the top of the edge groove pressing block 34. The cushion block 35 is frustum-shaped, the smaller end of the cushion block 35 is connected with the top of the edge groove pressing block 34, and the larger end of the cushion block 35 is in contact with the edge groove pressing rod 33.
[0035] The circular groove shaping mechanism 2 is arranged at the other end of the shaping table 1 and includes two vertically arranged columns 21. The gap between the two columns 21 is greater than the width of the plate, and a plurality of vertically arranged and equally spaced insertion holes are respectively arranged on the two columns 21. The circular groove shaping mechanism 2 further includes a pressing frame and a circular groove pressing block 26. The pressing frame includes an insertion column 22 that can be inserted into the insertion hole. A circular groove pressing rod 23 is movably connected to the insertion column 22, and a support rod 25 in contact with the circular groove pressing block 26 is connected to the bottom of the circular groove pressing rod 23.
[0036] The round groove pressing rod 23 is L-shaped, including a connecting part 231 and a holding part 232 that are vertically connected. The connecting part 231 has a cylindrical structure. The connecting part 231 is slidably sleeved outside the inserting post 22. A locking screw rod 24 arranged radially along it is threadedly connected to the connecting part 231. Loosen the locking screw rod 24, and the connecting part 231 can slide on the inserting post 22 to adjust its axial position. Tighten the locking screw rod 24, and the locking screw rod 24 presses inward against the inserting post 22, which can fixedly connect the connecting part 231 and the inserting post 22. The support rod 25 is vertically connected to the bottom of the holding part 232. A layer of cushion is provided at the bottom end of the support rod 25. The bottom end of the support rod 25 contacts the top surface of the round groove pressing block 26 and presses down the round groove pressing block 26. The shape and size of the bottom of the round groove pressing block 26 are adapted to the round groove of the plate.
[0037] A layer of soft copper is provided on the bottom surfaces of both the round groove pressing block 26 and the edge groove pressing block 34. During the process of shaping the plate by the round groove pressing block 26 and the edge groove pressing block 34, the bottoms of the round groove pressing block 26 and the edge groove pressing block 34 are respectively press-connected to the round groove and the edge groove of the plate.
[0038] Generally, the plate has four round grooves, and a circle of edge grooves is provided at the edge of the plate. When performing the edge groove shaping of the plate, place the plate on the shaping table 1. According to the position and thickness of the plate, adjust the height of the slider 32 in the sliding groove 37 so that when the edge groove pressing rod 33 presses against the edge groove pressing block 34, it is in a horizontal state. Place the edge groove pressing block 34 on the edge groove of the plate, and press down the edge groove pressing rod 33 to apply a downward pressure on the edge groove pressing block 34. The edge groove pressing block 34 presses the edge groove of the plate to shape it. Since the length of the edge groove pressing block 34 is limited, it is necessary to adjust the position of the plate multiple times so that the edge groove pressing block 34 presses and shapes all the edge grooves of the plate. When performing the round groove shaping of the plate, place the plate on the shaping table 1, place the round groove pressing block 26 on the round groove and make the two coaxial. Insert the inserting post 22 into the jack, fix the round groove pressing rod 23 on the inserting post 22 through the locking screw rod 24, press down the round groove pressing rod 23 so that the support column contacts the center of the round groove pressing block 26. The round groove pressing rod 23 presses down to apply a downward pressure on the round groove pressing block 26, and the round groove pressing block 26 presses and shapes the round groove of the plate.
[0039] The utility model has a simple structure, is convenient to operate and use, and has a low production and manufacturing cost. Through the edge groove pressing block 34 and the round groove pressing block 26, the sealing grooves of the plate can be quickly pressed and shaped, with high operation efficiency. There is no need for the plate to be returned to the factory or outsourced for repair, saving a large amount of repair costs, greatly reducing the time consumption, enabling the plate to be put into use as soon as possible, and greatly reducing the impact on production. A layer of copper provided at the bottoms of the edge groove pressing block 34 and the round groove pressing block 26 avoids scratching the plate.
[0040] The above embodiments are only preferred embodiments of the present utility model and do not limit the technical solutions of the present utility model. Any technical solutions that can be achieved on the basis of the above embodiments without creative efforts shall be regarded as falling within the scope of the protection of the rights of the patent of the present utility model.
