Abstract
The utility model relates to a plunger oil cylinder of a hydraulic press. The plunger oil cylinder of a hydraulic press comprises a cylinder body; one end of the cylinder body is a closed end, and the other end is an open end; a guide sleeve is mounted on the inner wall of the cylinder body at the open end; a plunger matched with the guide sleeve is inserted into the inner chamber of the cylinder body from the inner hole of the guide sleeve; seal rings and a wear ring are arranged on the inner wall of the guide sleeve; a copper lining is embedded on the inner wall of one end, close to the inner chamber of the cylinder body, of the guide sleeve; and the inner wall of the copper lining is matched with the outer wall of the plunger. In the plunger oil cylinder of a hydraulic press, the guide length of the plunger is increased, and the running precision of a slide block is improved; due to tenacity of copper, when the plunger deflects, the friction between the plunger and the copper lining enables copper to deform and copper cuttings are not produced, so that falling of the copper cuttings is avoided, and the normal running of the oil cylinder and a hydraulic system is ensured; besides, the copper lining is convenient to change after being worn, and time and labor are saved.
Description
Technical field
The utility model relates to a kind of hydraulic press, particularly a kind of hydraulic press plunger cylinder.
Background technique
Existing hydraulic press plunger cylinder comprises cylinder body; One end of cylinder body is a closed end; The other end is an opening end, and the inboard wall of cylinder block of opening end is equipped with guide sleeve, inserts the inner chamber of cylinder body from the endoporus of guide sleeve with the suitable plunger of guide sleeve; The inwall of guide sleeve is provided with seal ring and wear ring, and the wear ring coupled columns is filled in the row guiding.There is following deficiency in such structure:
(1) use sufficient stroke when plunger, unbalance loading occurs or lead when bad, plunger will with the guide sleeve friction, cause the damage of guide sleeve.
(2) guide sleeve damages and causes plunger crooked more, causes the interior wall friction of plunger and cylinder body, causes inboard wall of cylinder block to damage.
(3) after the guide sleeve wearing and tearing, repair difficulty and maybe can not repair.
(4) metal fillings of guide sleeve damage formation falls in the hydraulic oil, will cause phenomenons such as oil cylinder leakage of oil, especially can cause the fault of hydraulic system.
The model utility content
The purpose of the utility model is, overcomes the problem that exists in the existing technology, provides a kind of reliability high hydraulic press plunger cylinder.
For solving above technical problem; A kind of hydraulic press plunger cylinder that the utility model provided comprises cylinder body, and an end of said cylinder body is a closed end; The other end is an opening end; The inboard wall of cylinder block of said opening end is equipped with guide sleeve, inserts the inner chamber of said cylinder body with the suitable plunger of said guide sleeve from the endoporus of guide sleeve, and the inwall of said guide sleeve is provided with seal ring and wear ring; The inwall near inner chamber of cylinder block one end of said guide sleeve is embedded with copper bush, and the inwall of said copper bush and the outer wall of said plunger are suitable.
With respect to existing technology, the utility model has been obtained following beneficial effect: at the inner termination setting-in copper bush of guide sleeve, increased the guiding length of plunger, improved the running precision of slide block; The toughness of copper makes when plunger is crooked that the friction of plunger and copper bush can only make the copper distortion, can't produce copper scale, thereby avoid dropping of metal fillings, has guaranteed the normal operation of oil cylinder and hydraulic system; In addition, it is convenient that copper bush wearing and tearing back is changed, and material-saving saves time.
Description of drawings
Fig. 1 is the structural representation of the utility model hydraulic press plunger cylinder.
Fig. 2 is the enlarged view at A position among Fig. 1.
Among the figure: 1 cylinder body; 2 plungers; 3 guide sleeves; The 3a seal ring; The 3b wear ring; The 3c copper bush.
Embodiment
Like Fig. 1 and shown in Figure 2, the hydraulic press plunger cylinder of the utility model comprises cylinder body 1; One end of cylinder body 1 is a closed end, and the other end is an opening end, and the inboard wall of cylinder block of opening end is equipped with guide sleeve 3; Insert the inner chamber of cylinder body 1 from the endoporus of guide sleeve with the suitable plungers 2 of guide sleeve 3; The inwall of guide sleeve 3 is provided with seal ring 3a and wear ring 3b, and the inwall near inner chamber of cylinder block one end of guide sleeve 3 is embedded with copper bush 3c, and the outer wall of the inwall of copper bush 3c and plunger 2 is suitable.
Except that the foregoing description, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
